System composition and function

Comprehensive training device for mechanical installation and adjustment technology This device is mainly composed of training platform, power source, mechanical installation and adjustment objects (mechanical transmission mechanism, multi-stage gearbox, two-dimensional table, intermittent rotary table, dental clutch mechanism, punch Mechanism, etc.) consists of tools, measuring tools and other parts commonly used by fitters.

1. Training platform: It adopts iron double-layer matte dense grain spray plastic structure, including operation area and mechanical equipment adjustment area. The operation area is mainly composed of solid wood countertops, rubber pads, etc., which are used for benchwork processing and assembling various mechanical parts (the box part is made of aluminum alloy material); the mechanical installation and adjustment area uses aluminum alloy profile operation tabletops, where students can install and Adjust various mechanical mechanisms.

2. Mechanical transmission mechanism: It is mainly composed of timing belt, chain, gear, worm and other transmission mechanisms; through the installation, adjustment and detection of students on the platform, master the assembly and adjustment skills of mechanical transmission mechanism.

3. Multi-stage gearbox: It has a dual-shaft three-stage variable-speed output, one of which has a forward and reverse function, and the top is protected by transparent plexiglass. It is mainly composed of box, gear, spline shaft, spacer sleeve, key, angular contact bearing, deep groove ball bearing, spring, end cover, sliding fork, rack and pinion mechanism, gear shift mechanism, etc., which can complete multiple stages Gearbox assembly process training.

4. Two-dimensional worktable: It is mainly composed of ball screw, linear guide, table, pad, bearing, support, end cover, etc. The table top is made of aluminum alloy, and it is divided into upper and lower (X-axis, Y-axis) two layers. The lower layer is controlled by a multi-stage gearbox via gear transmission to achieve back and forth operation of the table. The hand wheel realizes manual control; it can complete the assembly process of linear guides, ball screws, two-dimensional worktables and accuracy testing training.

5. Reducer: It is mainly composed of spur gear, angular contact bearing, deep groove ball bearing, bracket, shaft, end cover, key, etc. Can complete the assembly process training of the reducer.

6. Intermittent rotary table: It is mainly composed of four-slot sheave mechanism, worm gear, thrust ball bearing, angular contact bearing, table surface, bracket, etc. The multi-stage gearbox realizes the intermittent turning function after indexing by chain drive, gear drive, worm gear and four-slot sheave mechanism; it can complete the assembly and adjustment training of worm gear, four-slot sheave, bearing, etc.

7, tooth-embedded clutch mechanism: mainly composed of bracket, bearings, two half clutches, operating levers, etc., at work, use the joystick to drive the slip ring to axially move the half clutch to achieve separation and engagement. Can complete the assembly process training of the clutch mechanism.

8. Punch mechanism: It is mainly composed of crankshaft, connecting rod, slider, bracket, bearing, etc., and cooperates with intermittent rotary table to realize the simulation of the material pressing function. Can complete the assembly process training of the punch mechanism.

9. Power source: equipped with AC geared motor, governor, power control box, etc. to provide power source for mechanical system. The power control box is equipped with a speed regulating motor power interface and a travel switch interface.

10. Installation and adjustment tools: There are mainly set tools (34 pieces), bench vise, scribe plate, pull horse, copper rod, impact sleeve, chain cutter, impact wrench. The set of tools consists of a tool box, an allen wrench, a dead wrench, an adjustable wrench, a file, a tap, a hinge, a gauge, a sample punch, a hammer, a die, a die holder, a screwdriver, a saw bow, a needle-nose pliers, a vise, and the like.

11. Commonly used measuring tools: mainly composed of vernier calipers, universal vernier protractors, width protractors, dial gauges, micrometers, feeler gauges, spirit levels, etc .; through the use of measuring tools to measure, enable students to master the use of commonly used measuring tools, and master the testing methods of mechanical assembly Wait.
