The motor end cover, a rear cover installed behind the motor housing, serves one of the main functions of precisely fixing and supporting the motor rotor through bearing housings and stops, ensuring the correct spatial position of its shaft. Therefore, holes need to be drilled to install bearings and other fixing components. These components play a crucial role in maintaining the internal structure of the motor. After drilling, burrs or flash may remain around the holes, requiring manual grinding and finishing.

The other end of the fixed sleeve is connected to a fixed frame through a rotating rod, and a limit rod is provided at the upper end of the fixed frame. A first motor is installed at the upper end of one set of adjusting rods.
[0004] While the above solution achieves the grinding of the motor end cover, it can only grind the outer surface of the motor end cover and cannot grind the holes on the motor end cover, making it difficult to accurately install bearings or other components during assembly. Utility Model Content
[0005] The main purpose of this utility model is to provide a grinding device for the production of motor end caps. By setting up a positioning mechanism and a clamping mechanism, it solves the problem that it is impossible to grind the holes on the motor end caps, making it difficult to accurately install bearings or other components in place during the assembly process.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A grinding device for producing motor end caps, comprising:
[0008] The support frame is connected to a grinding device via a drive component;
[0009] The positioning mechanism includes a hydraulic cylinder fixedly connected to the inner wall of the support frame, and a support platform fixedly connected to the output end of the hydraulic cylinder for positioning the motor end cover.
[0010] The clamping mechanism includes a servo motor fixedly connected to the inner wall of the support frame, a forward and reverse ball screw fixedly connected to the output end of the servo motor, and a first clamping member and a second clamping member movably disposed on the outer wall of the forward and reverse ball screw.
[0011] Preferably, the first clamping member includes a movable seat threadedly connected to a forward and reverse ball screw, a clamping block fixedly connected to the outer wall of the movable seat, and a limiting plate fixedly connected to the outer wall of the clamping block.
[0012] Preferably, the first clamping member further includes a drive motor fixedly connected to the outer wall of the clamping block, and a guide plate fixedly connected to the output end of the drive motor.
[0013] Preferably, the first clamping member further includes a storage groove formed on the inner side wall of the clamping block, a connecting spring fixedly connected to the bottom of the storage groove, a locking block fixedly connected to the end face of the connecting spring, an electromagnet embedded in the storage groove, and two sets of locking grooves arranged in a ring array on the outer side wall of the guide plate.
[0014] Preferably, the clamping mechanism further includes a slide rod fixedly connected to the opposite side of the support frame, and the outer side walls of both sets of limiting plates are provided with through holes that match the size of the slide rod.
[0015] Preferably, the second clamping member and the first clamping member have the same structure, and the two are symmetrically arranged about the vertical plane of the forward and reverse ball screw.
[0016] Preferably, the driving component includes a horizontal push rod fixedly connected to the inner side wall of the support frame, a transmission block fixedly connected to the output end of the horizontal push rod, an electric lift fixedly connected to the bottom of the transmission block, a bearing plate fixedly connected to the output end of the electric lift, a rotary motor fixedly connected to the bottom of the bearing plate, and a bearing disk fixedly connected to the output end of the rotary motor.
[0017] The grinding device is fixedly connected to the bottom of the support plate.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] I. In this utility model, the motor end cover is sleeved on the outer surface of the support platform and manually made to be horizontal. Then, the servo motor is started, which drives the forward and reverse ball screw to rotate, thereby driving the two movable seats and the clamping block to move towards each other until the outer surface of the guide plate abuts against the bottom edge of the motor end cover. At this time, the clamping block will continue to move, thereby driving the motor end cover to move towards each other until the outer wall of the motor end cover abuts against the clamping block. Finally, the motor end cover is fixed by the two clamping blocks.
[0020] II. In this utility model, by energizing the electromagnet, it becomes magnetic, thereby attracting the locking block and compressing the connecting spring until the locking block is completely retracted into the storage groove. Then, the drive motor is started, thereby driving the guide plate to rotate until the opening of the other locking groove is aligned with the storage groove. At this time, the electromagnet is de-energized. Under the action of the connecting spring, the locking block will slide half out of the storage groove and insert into the inside of the locking groove, thereby fixing the guide plate. At this time, the guide plate is in a horizontal state, thus preventing the motor end cover from falling off. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] Example 1: As Figure 1-6 As shown, a grinding device for producing motor end caps includes:
[0030] Support frame 1, and grinding device 2 is connected to support frame 1 via drive component;
[0031] The positioning mechanism includes a hydraulic cylinder 301 fixedly connected to the inner wall of the support frame 1, and a support platform 302 fixedly connected to the output end of the hydraulic cylinder 301 for positioning the motor end cover. The support platform 302 is shaped like a frustum and can be adapted to motor end covers with different inner diameters.
[0032] The clamping mechanism includes a servo motor 401 fixedly connected to the inner wall of the support frame 1, a forward and reverse ball screw 402 fixedly connected to the output end of the servo motor 401, and a first clamping member and a second clamping member movably disposed on the outer wall of the forward and reverse ball screw 402.
[0033] The first clamping component includes a movable seat 403 threadedly connected to the forward and reverse ball screw 402, a clamping block 404 fixedly connected to the outer wall of the movable seat 403, and a limiting plate 407 fixedly connected to the outer wall of the clamping block 404. The forward and reverse ball screw 402 is rotated by the servo motor 401, thereby driving the clamping block 404 to make linear motion.
[0034] The first clamping component also includes a drive motor 405 fixedly connected to the outer wall of the clamping block 404, and a guide plate 406 fixedly connected to the output end of the drive motor 405. The angle of the guide plate 406 can be adjusted by the drive motor 405, thereby rotating the guide plate 406 to an inclined state or a horizontal state.
[0035] The first clamping component also includes a storage groove formed on the inner side wall of the clamping block 404, a connecting spring 409 fixedly connected to the bottom of the storage groove, a locking block 4010 fixedly connected to the end face of the connecting spring 409, an electromagnet 4011 embedded in the storage groove, and two sets of locking slots 4012 arranged in a ring array on the outer side wall of the guide plate 406. The outer diameter of the locking block 4010 is equal to the inner diameter of the locking slot 4012, and the locking block 4010 is made of ferromagnetic material. When the electromagnet 4011 is energized and has magnetic force, it will attract the locking block 4010 and compress the connecting spring 409 until the locking block 4010 is completely retracted into the storage groove.
[0036] The clamping mechanism also includes a slide rod 408 fixedly connected to the opposite side of the support frame 1, and the outer side walls of the two sets of limiting plates 407 are provided with through holes that match the size of the slide rod 408.
[0037] The second clamping member has the same structure as the first clamping member. Both are symmetrically arranged about the vertical plane of the forward and reverse ball screw 402. The limiting plates 407 of both clamping members are sleeved on the outer surface of the slide bar 408. The vertical plane of the forward and reverse ball screw 402 coincides with the central axis of the bearing platform 302.
[0038] By fitting the motor end cover onto the outer surface of the support platform 302 and manually aligning it horizontally, the servo motor 401 is started, driving the forward and reverse ball screw 402 to rotate. This causes the two movable seats 403 and the clamping block 404 to move towards each other until the outer surface of the guide plate 406 abuts against the bottom edge of the motor end cover. At this point, the clamping block 404 moves, causing the motor end cover to move towards each other until the completed motor end cover abuts against the clamping block 404. Finally, the two clamping blocks 404 fix the motor end cover in place. Then, the electromagnet 4011 is energized, giving it the ability to... The magnetic force attracts the locking block 4010 and compresses the connecting spring 409 until the locking block 4010 is fully retracted into the storage slot. Then, the drive motor 405 is started, which drives the guide plate 406 to rotate until the opening of the other locking slot 4012 is aligned with the storage slot. At this time, the electromagnet 4011 is de-energized. Under the action of the connecting spring 409, the locking block 4010 will slide halfway out of the storage slot and insert into the inside of the locking slot 4012 to fix the guide plate 406. At this time, the guide plate 406 is in a horizontal state, thus preventing the motor end cover from falling off.
[0039] Example 2: Figure 1-6 As shown, a grinding device for producing motor end caps includes:
[0040] Support frame 1, and grinding device 2 is connected to support frame 1 via drive component;
[0041] The positioning mechanism includes a hydraulic cylinder 301 fixedly connected to the inner wall of the support frame 1, and a support platform 302 fixedly connected to the output end of the hydraulic cylinder 301 for positioning the motor end cover, wherein the support platform 302 is in the shape of a frustum.
[0042] The clamping mechanism includes a servo motor 401 fixedly connected to the inner wall of the support frame 1, a forward and reverse ball screw 402 fixedly connected to the output end of the servo motor 401, and a first clamping member and a second clamping member movably disposed on the outer wall of the forward and reverse ball screw 402.
[0043] The driving components include a horizontal push rod 501 fixedly connected to the inner wall of the support frame 1, a transmission block 502 fixedly connected to the output end of the horizontal push rod 501, an electric lift 503 fixedly connected to the bottom of the transmission block 502, a bearing plate 504 fixedly connected to the output end of the electric lift 503, a rotary motor 505 fixedly connected to the bottom of the bearing plate 504, and a bearing disk 506 fixedly connected to the output end of the rotary motor 505.
[0044] The grinding device 2 is fixedly connected to the bottom of the bearing plate 506.
[0045] After the motor end cover is fixed, the hydraulic cylinder 301 drives the support platform 302 to move down until the support platform 302 separates from the motor end cover. Then, the horizontal push rod 501 is activated to move the grinding device 2 horizontally, thereby adjusting the projection position of the grinding device 2 in the front-to-back direction on the motor end cover. The rotary motor 505 is activated to drive the grinding device 2 to rotate, thereby adjusting the projection position of the grinding device 2 in the left-to-right direction on the motor end cover. Through the cooperation of the horizontal push rod 501 and the rotary motor 505, the grinding device 2 can grind the holes at different positions on the motor end cover.
