HRA-1003 Basic Mechanical and Mechanical Automatic Control Set-up Training Equipment

I. Overview of equipment

This device is combined with the vocational schools, technical colleges and universities "machinery manufacturing technology", "electromechanical equipment installation and maintenance", "mechanical assembly", "mechanical equipment assembly and automatic control" and other specialties. Mechanical equipment assembly and automatic control" and other professional and developed, the students through the assembly and adjustment of power transmission mechanism, extrusion crusher, punch press mechanism, lifting and handling machine, chain conveyor and other institutions, strengthen the students of various types of transmission fault diagnosis and maintenance of the comprehensive ability to cultivate the reading and drawing of assembly drawings and parts drawings, basic operation of clamping, assembly of parts and mechanisms Craft and adjustment, assembly quality inspection and other skills, so that students can achieve "learning to use" and learn new knowledge in practice.

Second, the characteristics of the equipment

Strong practicality: set up various practical tasks according to relevant vocational standards, industry standards and job requirements, based on improving students' vocational skills, and really improve students' vocational competitiveness in a comprehensive manner.

Wide applicability: based on the work process of basic operation, assembly, measurement and adjustment, and quality inspection of clamp work in mechanical assembly and adjustment technology, it can meet the needs of practical training teaching, engineering training and vocational skills competition.

Modular design: It consists of two major components, mechanical basic mechanism and mechanical automation mechanism. Mechanical basic mechanism is composed of another seven small parts, such as: power transmission mechanism, extrusion crusher, press mechanism, lifting and carrying machine, and so on. Can do to realise the machine tool automatic tool automation control module training, can also be done to the small parts of the series and parallel connection of the mechanical foundation module training.

Strong synthesis Including ratchet mechanism, worm gear mechanism, topological mechanism and other institutions, can train students to read the map ability, how to correctly select and use common tools and gauges, assembly quality inspection, choose the appropriate assembly process, perfect the defects of the students, improve the comprehensive professional level of the students.

Third, the system composition and function

This device is mainly composed of training table, power source, mechanical adjustment objects (power transmission mechanism, extrusion crusher, punch press mechanism, lifting and carrying machine, etc.), adjustment tools, commonly used gauges and other components.

Training table: the use of plastic spraying structure, including the operation area and mechanical adjustment of two parts of the area. The operation area is mainly composed of solid wood table and rubber pads, etc., used for clamp processing and assembly of various types of mechanical parts; mechanical assembly and adjustment of the area using casting table, students can install and adjust a variety of mechanical institutions on it.

Power transmission mechanism: mainly consists of sprocket, chain, synchronous belt, synchronous belt wheel, deep groove ball bearings, angular contact bearings, through the cover, bearing housing, sleeve, T-screw M8, etc., is responsible for the transmission of power from the source of the power to other positions, so as to achieve the movement of the whole machine. Can complete the assembly process of power transmission mechanism practical training.

Extruding crusher: it is mainly composed of bearing seat, crank, joint bearing, double stud, connecting rod, rocker, angular contact bearing, deep groove ball bearing, through cover, T-screw M8, etc. It can simulate crushing and extruding through the four-bar mechanism. It can complete the assembly and adjustment of extrusion crusher practical training.

Punching mechanism: mainly composed of joint bearings, double-headed studs, punches, seats, etc. It can realise the simulation of pressing function. It can complete the assembly process of press mechanism practical training.

Lifting and carrying machine: it is mainly composed of pawl, ratchet wheel, tension spring, straight tooth cylindrical gear, deep groove ball bearing, angular contact bearing, sleeve, L block, T screw M8, etc. By stopping the intermittent climbing movement of the pawl and the movement of the L block driven by double crank mechanism, it can simulate the function of lifting and carrying heavy loads, etc. It can complete the practical training of assembly process of press mechanism. It can complete the assembly and adjustment training of ratchet mechanism and bearing.

Chain conveyor: It is mainly composed of worm gear, worm gear, chain wheel, chain, deep groove ball bearing, single row tapered roller bearing, bearing seat, L-shaped block, T-shaped screw M8, etc. The power is transmitted to the active chain wheel through the worm gear mechanism, so as to realise the slow movement of the chain and achieve the continuous feeding of materials. It can complete the assembly and adjustment training of worm gear and bearing.

Lathe automatic tool mechanism: mainly composed of cam, gear, rack, T-guide, pendulum, L-block, push rod, deep groove ball, etc., can simulate the automatic tool in the lathe. Can complete the assembly process of lathe automatic tool mechanism practical training.

Tandem-parallel topology mechanism: mainly composed of crank, joint bearing, double stud, connecting rod, deep groove ball bearing, rod, inner cam, T-screw M8 and so on. Can complete the assembly process of series-parallel topology mechanism practical training.

One-axis lathe automatic tooling mechanism: mainly composed of base plate, middle slide plate, linear guide, crank, joint bearing, double-headed stud, slider, isometric block, motor support, etc. It can realise the longitudinal feeding of lathe automatic tooling and automatic round-trip filter function simulation. It can complete the linear guide assembly process and accuracy testing practical training.

2-axis lathe automatic tooling mechanism: it is mainly composed of upper slide plate, slider, contour block, screw, crank, joint bearing, double-head bolt, double-row angular contact bearing, deep groove ball bearing, etc. It can realise the transverse feeding of lathe automatic tooling through the movement of screw. It can complete the assembly process of linear guide and ball screw and precision testing practical training.

Power source: equipped with AC gear motor, power control box, etc. to provide power source for the mechanical system.

Assembly tools: mainly include set of tools (19 pieces), table vise, purple copper bar, pulling horse, round nut wrench, chain cutter, etc. The set of tools consists of tool box, hexagonal spanner, dull wrench, movable spanner, taps, reamer, hammer, screwdriver, sharp-nosed pliers and so on.

Commonly used gauges: mainly consists of vernier calipers, straightedge, lever-type percentile table, etc. Through the use of gauges for measurement, it can enable students to master the use of commonly used gauges, and master the quality inspection of mechanical assembly and so on.
