The novel energy automobile aluminum alloy engine end cover processing device and the working principle of the novel energy automobile aluminum alloy engine end cover processing method are as follows:
after the engine end cover is placed on the bearing plate 5, under the action of the common gravity of the engine end cover and the bearing plate 5, the bearing plate 5 drives the screw rod 4 to move downwards, and as the thread lead angle of the screw rod 4 is larger than the equivalent friction angle of the inner side wall of the central disc 3, when the screw rod 4 moves downwards, the central disc 3 rotates by a certain angle under the limit action of the bearing sleeve 2, the connecting clamp 61 rotatably arranged on the outer side of the central disc 3 rotates along with the central disc, and under the limit action of the slide rail 62, the slide block 63 drives the connecting column 64 fixedly arranged on the upper part of the connecting clamp to move towards the inner side of the slide rail 62, so that three clamping seats 7 are synchronously close to each other at the moment, and the whole device can complete the function of clamping the side wall of the engine end cover at the moment;
when the clamping block 83 is attached to the engine end cover, under the reaction force of the clamping block 83 extruding the pressure of the engine end cover, the clamping block 83 extrudes the piston column 82 to enable the piston plate 81 to move towards the outer side of the inner cavity of the clamping seat 7, at the moment, the piston plate 81 can extrude the air in the inner cavity of the clamping seat 7, when the air pressure reaches the threshold value of the one-way air valve arranged at the air outlet pipe 86, the high-pressure air in the inner cavity of the clamping seat 7 can be sprayed out through the air outlet pipe 86, at the moment, dust and fragments on the outer wall of the engine cover plate can be blown off, the outer wall of the engine cover plate is prevented from being cleaned manually before workers process, meanwhile, under the elastic action of the buffer spring 84, the clamping block 83 can play a certain buffering role in clamping the engine end cover, and the safety of the whole device in clamping is ensured;
it should be noted that when the engine end cover is required to be taken out after being processed, the three clamping seats 7 drive the clamping blocks 83 to retract, at the moment, under the action of the elastic force of the buffer springs 84, the piston plate 81 returns to the middle part of the inner cavity of the clamping seat 7 again, so that the air pressure inside the clamping seat 7 is smaller than the external atmospheric pressure, the one-way valve at the air inlet pipe 85 is opened at the moment, and then the external air can supplement the air inside the clamping seat 7 through the air inlet pipe 85, thereby ensuring that the whole device plays a role of automatic cleaning again when clamping the next engine end cover;
when polishing the other surfaces of the engine end cover, and polishing the parts clamped by the engine end cover, the moving wheel 91 is rotated by starting the moving motor 92, and at the moment, the moving wheel 91 drives the engine end cover to rotate under the friction force of the moving wheel 91, and at the moment, the clamping parts clamped by the clamping blocks 83 are changed, so that the whole device is used for processing all the surfaces of the engine end cover under the condition that the engine end cover is not required to be clamped for the second time, the precision of workers during processing is ensured, and the working efficiency of the workers is greatly improved;
it should be noted that, when the moving wheel 91 rotates, because the magnetic blocks on the moving wheel 91 are arranged in an indirect array, when the magnetic blocks and the magnetic plate 94 are on the same straight line, the magnetic force between the magnetic blocks and the magnetic plate 94 is larger, the magnetic plate 94 can be adsorbed, at this time, the magnetic plate 94 moves towards the left side of the inner cavity of the movable cavity 93, the return spring 97 is in a stretched state, the movable rod 95 drives the valve 96 to move to the left side, when an included angle exists between the magnetic blocks and the magnetic plate 94, the magnetic force between the magnetic blocks is smaller, under the action of the elastic force of the return spring 97, the magnetic plate 94 drives the movable rod 95 to move the valve 96 to the right side, so that the valve 96 can shake back and forth along with the air to a certain extent, and then air current is generated to realize the blowing of adhered scraps on the side wall of the engine end cover, so that the moving wheel 91 is prevented from rolling on the scraps when rotating, the clamping center of the whole device is changed, and the precision of the whole device for clamping the engine end cover is further ensured.

and setting the clamping contact area and the clamping surface radian of the clamping block (83) according to the comprehensive clamping area and the clamping radian, and manufacturing the clamping block (83).
Wherein, the clamping area and the clamping radian are obtained by the following formula:
wherein S represents the clamping surface area of the clamping block (83); s is S mini Indicating that the ith type of engine end cover reaches a theoretical clamping contact area lower limit value for stable clamping; s is S 0i Indicating the theoretical optimal clamping contact area for the i-th type of engine end cover to achieve stable clamping; n represents the number of types of engine end covers; s is S minm Representing the minimum value in the area corresponding to the clamping range of the n types of engine end covers; h represents the clamping radian of the clamping block (83); h m The radian maximum for n types of engine end caps; h i Representing the radian of a clamping surface corresponding to the clamping range area corresponding to the clamping position of the ith type of engine end cover; h s The arc minimum for n types of engine end covers is indicated.
