Embodiment 1

[0029] refer to Figure 1-13, a new energy vehicle manufacturing grinding device, including a base 1 and an upper shell 2, the two symmetrical outer walls of the base 1 and the upper shell 2 are fixed and welded with a connecting plate 3, the connecting plate 3 on the base 1 and the upper shell 2 A vertically arranged hydraulic telescopic rod 4 is fixedly installed between the upper connecting plates 3, and a notch 39 is provided at the edge of the top surface of the base 1, and the bottom end of the upper shell 2 can be inserted into the notch 39, and the notch 39 There are soundproof rubber strips attached to the internal fixation, and a closed cavity 5 can be formed between the base 1 and the upper shell 2. When grinding the brake disc, first control the hydraulic telescopic rod 4 to drive the upper shell 2 to move upward, and then put the brake disc into the bottom between the seat 1 and the upper shell 2, and then control the hydraulic telescopic rod 4 to drive the upper ...

Embodiment 2

[0038] It is mentioned in Example 1 that if we control the rotation of the brake disc through a rotating shaft, the rotating shaft needs to be at the center of the brake disc, otherwise the brake disc will shake when it rotates. In Example 1, we can measure the brake disc It is placed at the center of the active grinding sheet 24 and the passive grinding sheet 25, but this method is cumbersome, and it is very unreasonable to need to measure each time the brake disc is placed. For this reason, we improve embodiment 1. Refer to figure 2 with 4 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the center of the top surface of the passive grinding sheet 25 is fixedly provided with a center alignment mechanism, and the center alignment mechanism includes a smooth surface fixedly welded on the center of the top surface of the passive grinding sheet 25. Rod 27, the outer wall of smooth rod 27 is slidably provided with round table 28...

Embodiment 3

[0040] In Example 1, we only grind the two sides of the brake disc, but when grinding the two sides of the brake disc, there will be sticky debris at the edge of the brake disc. When taking the brake disc, these debris will melt on the edge of the brake disc, which not only affects the aesthetics of the brake disc, but also affects the performance of the brake disc. For this reason, we further improve the embodiment 1, refer to Figure 5 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that an edge grinding mechanism is provided on the opposite side walls of the active grinding sheet 24 and the passive grinding sheet 25, and the edge grinding mechanism includes 24 and the strip groove 30 at the edge of the passive polishing sheet 25, the extension line of the strip groove 30 passes through the center of the active polishing sheet 24 and the passive polishing sheet 25, and the inside of the strip groove 30 is slidably provided with ...

Abstract

The invention relates to the technical field of mechanical polishing, in particular to a polishing device for new energy automobile manufacturing. The polishing device comprises a base and an upper shell, connecting plates are fixedly welded to the two symmetrical outer walls of the base and the upper shell, and a vertically-arranged hydraulic telescopic rod is fixedly installed between the connecting plate on the base and the connecting plate on the upper shell. A closed cavity can be formed between the base and the upper shell, a polishing mechanism is arranged in the closed cavity and comprises a motor fixedly installed in the middle of the top face of the upper shell through a support, the output end of the motor is fixedly connected with a circular shaft, the outer wall of the circular shaft is sleeved with a second cylinder, and a second external spline is fixedly welded to the outer wall of the circular shaft. A second internal spline used in cooperation with the second externalspline is arranged on the inner wall of the second cylinder, and the second external spline is inserted into the second internal spline all the time. The problem that in the prior art, the polishingdegrees of the two faces of a brake disc are inconsistent is solved, the beneficial effect is obvious, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical grinding, in particular to a grinding device for manufacturing new energy vehicles. Background technique [0002] In the manufacture of new energy vehicles, the brake disc is an indispensable part. There are many types of brake discs, which are characterized by thin walls. The disc and the center are formed by sand cores. Porosity, porosity, trachoma and other casting defects, the metallographic structure is medium flake type, graphite type, uniform structure, and low fracture sensitivity. At present, the automobile industry is in a stage of rapid development, so the demand for brake discs is also large. Since brake discs play a key role in automobile braking, the quality of brake discs will affect the braking effect and The safety factor of the car, when the current brake disc grinding device is grinding the brake disc, most of them are polished on one side. After one side is polished, the ot...
