Automobile hub double-face full-automatic polishing production line

Abstract

The invention discloses an automobile hub double-face full-automatic polishing production line which comprises a rack and a polishing mechanism. The rack is sequentially provided with a feeding mechanism, a hub polishing rotary table and a discharging mechanism, the polishing mechanism is located above the polishing mechanism, and the characteristics are that the feeding mechanism comprises a first chain plate conveyor, two guide plates and a stopping air cylinder; the hub polishing rotary table comprises a grinding collecting box, a hub polishing jacking table and an overturning tool; the overturning tool comprises a vertical plate, a wide type gas claw, two clamping connecting plates, two rotary air cylinders and two clamping blocks; the polishing mechanism comprises a support, an X-axisguide rail, an X-axis sliding base, a Y-axis sliding base, an X-axis electric cylinder, a Y-axis electric cylinder, a Z-axis electric cylinder, a Z-axis stretchable cylinder, an electric polishing head and a carrying mechanical arm; and the discharging mechanism at least comprises a second chain plate conveyor. The automobile hub double-face full-automatic polishing production line is used for automobile hub full-automatic polishing production, the front and back faces of a hub can be switched at will, and the reliability and the stability can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobile wheel hub production, in particular to a double-sided fully automatic grinding production line for automobile wheel hubs. Background technique [0002] The wheel hub is an important load-bearing part of the car. At present, most of the car hubs use aluminum alloy wheels. Therefore, in the production of automobile wheels, it is necessary to polish the outer surface of the wheels to remove burrs and flashes. [0003] In the Chinese utility model patent with the application number 201620942517.7, it discloses a wheel hub robot deburring production line, which is used to realize automatic grinding and deburring of the wheel hub, and its entire production line can automatically position, identify, deburr and grind and discharge the workpiece , the operator only needs to detect the workpiece at a long distance on the discharge roller table, which greatly protects the health of the workers and reduce...

AI Technical Summary

Problems solved by technology

[0004] First, because the loading and unloading system is transported by a roller table, a large and uneven gap is formed between adjacent rollers, so the force is not stable during the transportation of the wheel hub, and the wheel hub shakes, vibrates, and interacts with each other. Serious problems such as friction and collision are easy to damage the outer surface of the hub, and are also very unfavorable for the safety protection of the structure and shape of the product;

[0005] Second, because the hub is in slidable contact with each other on the rollers transported by the roller table, the hub will slide laterally along the width direction of the roller table during transportation, so when the hub moves to the end position, there is a position along the side Since the grabbing robot uses fixed-point coordinates to grab, when there is uncertainty in the position of the wheel hub, it cannot be accurately grabbed, and there is a problem that the grabbing robot is difficult to grab or empty, and the production stability and reliability are poor. ;

[0006] Third, because the hub on the hub fixture turntable cannot be reversed and switched, when grinding, only one side of the upper side can be polished, and double-sided grinding cannot be completed at one time, which has the problems of low production efficiency and high processing cost;

[0007] Fourth, when the wheel hub is grinding the wheel hub of the wheel hub fixture turntable, the grinding is dropped along the periphery of the wheel hub fixture turntable, and the grinding cannot be collected centrally, so there are problems such as low cleaning efficiency and poor effect
