Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0021] Please refer to Figures 1-5 The utility model provides a technical scheme: a die casting aluminum alloy motor end cover detection clamp, including fixed plate 1, one side surface of fixed plate 1 is fixedly connected with the lug 2, the upper surface of fixed plate 1 is fixedly connected with motor knob 3, the upper surface of fixed plate 1 is fixedly connected with the protection ring 4, the inside surface of fixed plate 1 is provided with clamping mechanism 5;
[0022] The clamping mechanism 5 comprises a lower groove base plate 501, a rotary motor 502, a rotating ball 503, an upper sliding ring 504, a connecting plate 505, a pushing block 506, a sliding ball 507, a clamping bottom plate 508, a clamping groove 509, a spring 510, a clamping block 511, a clamping slot 512, a driven block 513 and a plastic clamping pad 514. The inner side surface of the fixed plate 1 is fixedly connected with the lower groove base plate 501. The upper surface of the lower groove base plate 501 is fixedly connected with the rotary motor 502. The upper surface of the lower groove base plate 501 is slidingly connected with the rotating ball 503. The upper surface of the rotating ball 503 is slidingly connected with the upper sliding ring 504. One side surface of the upper sliding ring 504 is fixedly connected with the connecting plate 505. One side surface of the upper sliding ring 504 is fixedly connected with the pushing block 506. One side surface of the pushing block 506 is fixedly connected with the sliding ball 507. One side surface of the upper sliding ring 504 is slidingly connected with the clamping bottom plate 508. The upper surface of the clamping bottom plate 508 is provided with the clamping groove 509. The inner side surface of the clamping groove 509 is fixedly connected with the spring 510. One side surface of the spring 510 is fixedly connected with the clamping block 511. The upper surface of the clamping block 511 is fixedly connected with the clamping slot 512. One side surface of the clamping slot 512 is fixedly connected with the driven block 513. One side surface of the clamping slot 512 is fixedly connected with the plastic clamping pad 514. Through the arrangement of the lower groove base plate 501, the rotary motor 502, the rotating ball 503, the upper sliding ring 504, the connecting plate 505, the pushing block 506, the sliding ball 507, the clamping bottom plate 508, the clamping groove 509, the spring 510, the clamping block 511, the clamping slot 512, the driven block 513 and the plastic clamping pad 514, the fixed plate 1 and the clamping mechanism 5 are fixed on the plane through the hanging ear 2 during use. Then the alloy motor end cover to be detected is placed above the clamping bottom plate 508. The motor knob 3 starts the rotary motor 502. The motor 502 drives the upper sliding ring 504 and the pushing block 506 to rotate due to the arrangement of the connecting plate 505. The sliding friction of the lower groove base plate 501 and the upper sliding ring 504 is changed to rolling friction through the arrangement of the rotating ball 503, which reduces the wear between mechanisms and improves the service life of the device. Then the pushing block 506 pushes the driven block 513. The clamping block 511 carries the clamping slot 512 and the plastic clamping pad 514 to shrink inward due to the limiting of the clamping groove 509, so as to clamp the alloy motor end cover. The synchronous clamping of the alloy motor end cover in multiple ranges is ensured due to the arrangement of the upper sliding ring 504, the pushing block 506 and the driven block 513, which reduces the deviation of the motor end cover detection and reflects the true quality condition of the end cover. Moreover, the use of the motor 502 can save human resources during use.
[0023] Further, the hanging ears 2 are symmetrically arranged on both sides of the fixing plate 1, and the outer surface of the motor knob 3 is provided with a plurality of anti-skid lines. When the device is fixed horizontally, the hanging ears 2 and the motor knob 3 can provide uniform distributed support force. The symmetrically arranged hanging ears 2 can ensure that the fixing plate 1 and the whole device are balanced in the horizontal direction, and can prevent the device from tilting or shaking due to excessive force on one side, thereby providing a stable operating environment for subsequent motor end cover detection work. The anti-skid lines can increase the friction between the fingers and the surface of the knob, and can prevent the operator's hand from slipping when rotating the knob, especially in a working environment where the hands may be contaminated with oil or other liquids. This anti-skid design can effectively reduce accidents caused by hand slipping, such as finger injury caused by rotating parts.
[0024] Further, the rotating motor 502 is symmetrically provided with thirty groups of rotating balls 503, the upper sliding ring 504 is rotatably connected to the lower groove base 501 through the rotating balls 503, and the pushing block 506 is symmetrically provided with four groups of pushing blocks 506. When in use, the force between the lower groove base 501 and the upper sliding ring 504 can be evenly distributed on the rotating balls 503, so as to avoid excessive local pressure. When the rotating motor 502 drives the upper sliding ring 504 to rotate, the symmetrically distributed rotating balls 503 can make the support force of the upper sliding ring 504 from the lower groove base 501 more uniform, so as to ensure the smooth rotation of the upper sliding ring 504 and reduce the shaking caused by uneven force.
[0025] Further, the sliding ball 507 is provided with six groups of sliding balls 507 on one side surface of each group of pushing blocks 506, and the clamping groove 512 is linearly moved in the clamping groove 509 through the sliding ball 507. When in use, the large number of sliding balls 507 can significantly improve the smoothness of movement. When the pushing block 506 pushes the clamping groove 512 to move, the sliding ball 507 acts like a small roller, reducing the friction between the pushing block 506 and the clamping groove 512. This smooth movement can ensure that the clamping groove 512 can quickly and stably respond to the force of the pushing block 506, improve the response speed of the device, and multiple sliding balls 507 can effectively reduce the pressure on each sliding ball 507, which helps to reduce the wear of the sliding ball 507 and prolong its service life, thereby ensuring that the whole device can work stably for a long time.
[0026] Further, the clamping grooves 509 are symmetrically provided with four groups along the central axis of the clamping bottom plate 508, and the springs 510 are symmetrically provided with four groups along the central axis of the clamping bottom plate 508. Through the arrangement of the clamping grooves 509 and the springs 510, in use, the four symmetrically arranged clamping grooves 509 can ensure that the clamping grooves 512 uniformly shrink from four directions to the center, thereby exerting uniform clamping force on the motor end cover. This uniform clamping force can prevent the motor end cover from being damaged due to excessive local force, ensure that the motor end cover is tightly and uniformly clamped at the center position, and is conducive to improving the accuracy of detection.
[0027] Further, the clamping blocks 511 are slidably connected with the clamping grooves 509 through the springs 510, and the clamping blocks 511 are fixedly connected with the driven blocks 513 through the clamping grooves 512. Through the arrangement of the springs 510, in use, the springs 510 can play a buffering role, can absorb part of the impact force, prevent the clamping blocks 511 and the components connected therewith from being damaged due to sudden receipt of a large force, protect the clamping blocks 511 and the clamping grooves 512 and other components, prolong the service life of the device, and after a round of clamping is completed, the springs make the device return to the original position, realizing reciprocating work of the instrument.
[0028] Further, the plastic clamping pads 514 are symmetrically provided with four groups along the central axis of the clamping bottom plate 508, and the side surface of the plastic clamping pad 514 is provided with a plurality of anti-skid lines. Through the arrangement of the plastic clamping pads 514, in use, the four plastic clamping pads 514 symmetrically arranged along the central axis of the clamping bottom plate 508 can ensure that uniform clamping force is exerted on the motor end cover from four directions when the motor end cover is clamped, and when the plastic clamping pad 514 contacts and clamps the motor end cover, the anti-skid lines can increase the friction between the plastic clamping pad 514 and the motor end cover, effectively preventing the motor end cover from sliding during clamping, and ensuring that the motor end cover always remains in the correct detection position.
[0029] Working principle: when using, the fixed plate 1 and the clamping mechanism 5 are fixed on the plane through the hanging ear 2, then the alloy motor end cover to be detected is placed above the clamping bottom plate 508, the motor knob 3 is rotated, the motor knob 3 starts the motor 502, the motor 502 drives the upper sliding ring 504 and the pushing block 506 to rotate due to the setting of the connecting plate 505, the setting of the rotating bead 503 can change the sliding friction of the lower groove bottom plate 501 and the upper sliding ring 504 into rolling friction, reduce the wear between mechanisms, and improve the service life of the device, then the pushing block 506 pushes the driven block 513, the clamping block 511 carries the clamping groove 512 and the plastic clamping pad 514 inwards due to the limiting of the clamping groove 509, the alloy motor end cover is clamped, the process ensures the synchronization of the alloy motor end cover clamping in multiple ranges due to the setting of the upper sliding ring 504, the pushing block 506 and the driven block 513, reduces the deviation of the motor end cover detection, reflects the real quality condition of the end cover, and saves human resources during use, after use, the motor rotates, the driven block 513 rebounds to the original position due to the setting of the spring 510, and a cycle is completed.
