Description

Technical Field

[0001] This utility model relates to the field of end cap production technology, and in particular to a fixture for producing motor end caps. Background Technology

[0002] The motor end cover is an important component of the motor, often made of high-strength, corrosion-resistant metal materials such as aluminum alloy and cast iron. Its processing includes material pretreatment, milling, drilling, and tapping. In the material pretreatment stage, the selected material needs to be cut, sawed, and deburred to ensure a smooth surface free of scratches and burrs. Milling removes one or more layers from the material surface using a milling tool to achieve the required dimensional dimensions and surface roughness. Drilling involves creating holes in the milled material to secure the stator coils and rotor. Tapping involves threading the drilled holes to install bolts and nuts; a fixture is required to hold these components in place during the process.

[0003] The publication (announcement) number CN219986900U discloses a fixture for producing pump covers, including a fixed base plate, a mounting bracket mounted on the top of the fixed base plate, a drive motor mounted in the middle of the mounting bracket, and a motor drive shaft mounted on one end of the drive motor.

[0004] While the above solution uses two sets of fixing plates to hold and secure the pump cover to be processed, it cannot accurately position the end cover during clamping. This inability to achieve precise positioning will directly lead to uneven force distribution during clamping. This not only affects processing accuracy but may also damage the motor end cover, thereby impacting the overall performance and lifespan of the motor. Utility Model Content

[0005] The main purpose of this utility model is to provide a fixture for producing motor end caps. By setting a positioning mechanism, it solves the problem that the inability to accurately position the motor end cap directly leads to uneven force during the clamping process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixture for manufacturing motor end caps, comprising:

[0008] The base has a support frame fixedly connected to its top;

[0009] The positioning mechanism includes a hydraulic cylinder fixedly connected to the inner wall of the base, and a positioning cone fixedly connected to the output end of the hydraulic cylinder for supporting the motor end cover.

[0010] The clamping mechanism includes a drive member movably disposed on the top of the support frame, and a first clamping member and a second clamping member movably disposed on the outer side wall of the drive member for fixing the motor end cover.

[0011] Preferably, the positioning mechanism further includes an electric lift fixedly connected to the top of the support frame, a transmission block fixedly connected to the output end of the electric lift, and a connecting frame connected to the transmission block.

[0012] Preferably, the positioning mechanism includes a connecting rod fixedly connected to the bottom of the connecting frame, a drive motor fixedly connected to the inner side wall of the connecting rod, and a fixing plate fixedly connected to the output end of the drive motor.

[0013] Preferably, the top of the horizontal plate of the connecting frame has a through hole, and there are two sets of the overall structure consisting of the connecting rod, the drive motor and the fixing plate, with the two sets of the overall structure arranged symmetrically about the central axis of the through hole.

[0014] Preferably, the driving component includes a servo motor fixedly connected to the inner wall of the connecting frame, and a forward and reverse ball screw fixedly connected to the output end of the servo motor, wherein the perpendicular plane of the forward and reverse ball screw coincides with the perpendicular line of the through hole.

[0015] Preferably, the first clamping member includes a clamping plate threaded to the outer wall of the forward and reverse ball screw, a through hole formed in the side wall of the clamping plate, a mounting groove formed in the inner wall of the through hole, and a pulley rotatably connected to the inner wall of the mounting groove.

[0016] The second clamping member has the same structure as the first clamping member, and the two are symmetrically arranged about the vertical plane of the forward and reverse ball screw.

[0017] Preferably, the clamping mechanism further includes a slide rod fixedly connected to the inner sidewall of the support frame, the clamping plate being sleeved on the outer sidewall of the slide rod through a through hole, and the outer sidewall of the pulley extending to the outer surface of the mounting groove and abutting against the outer sidewall of the slide rod.

[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 fitted onto the positioning cone. Due to the shape of the positioning cone, it can be adapted to motor end covers with different inner diameters. After the motor end cover is fitted, the hydraulic cylinder is activated, and the transmission block drives the connecting frame to descend. The fixing plate can be rotated by the drive motor to adjust the position of the fixing plate, so that the other end of the fixing plate is always above the motor end cover. Then, the two fixing plates are pressed against the top of the motor end cover, so that the motor end cover is horizontally fitted onto the outer surface of the positioning cone, thereby achieving the positioning of the motor end cover.

[0020] II. In this utility model, the servo motor drives the forward and reverse ball screw to rotate, thereby moving the two clamping plates downward to clamp and fix the motor end cover. During this process, the pulley will roll on the outer wall of the slide bar, which not only achieves the stability of the clamping plate movement, but also reduces the wear on the slide bar and improves the service life of the device. After the motor end cover is fixed, the hydraulic cylinder is started, which drives the positioning cone to move downward until the positioning cone separates from the motor end cover. At this time, the motor end cover can be processed. Attached Figure Description

[0027] 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.

[0028] Example 1: As Figure 1-5 As shown, a fixture for producing motor end caps includes:

[0029] Base 1, with a support frame 2 fixedly connected to the top of base 1;

[0030] The positioning mechanism includes a hydraulic cylinder 301 fixedly connected to the inner wall of the base 1, and a positioning cone 302 fixedly connected to the output end of the hydraulic cylinder 301 for supporting the motor end cover.

[0031] The clamping mechanism includes a drive member movably disposed on the top of the support frame 2, and a first clamping member and a second clamping member movably disposed on the outer side wall of the drive member for fixing the motor end cover.

[0032] The positioning mechanism also includes an electric lift 303 fixedly connected to the top of the support frame 2, a transmission block 304 fixedly connected to the output end of the electric lift 303, and a connecting frame 305 connected to the transmission block 304. The connecting frame 305 is located at the bottom of the support frame 2 and is moved by the electric lift 303 and the transmission block 304.

[0033] The positioning mechanism includes a connecting rod 306 fixedly connected to the bottom of the connecting frame 305, a drive motor 307 fixedly connected to the inner wall of the connecting rod 306, and a fixing plate 308 fixedly connected to the output end of the drive motor 307. The drive motor 307 drives the fixing plate 308 to rotate, thereby adjusting the position of the fixing plate 308 so that the other end of the fixing plate 308 is above the motor end cover.

[0034] The top of the horizontal plate of the connecting frame 305 has a through hole. There are two sets of the overall structure consisting of the connecting rod 306, the drive motor 307 and the fixing plate 308. The two sets of overall structures are symmetrical about the central axis of the through hole.

[0035] By fitting the motor end cover onto the positioning cone 302, the shape of the positioning cone 302 can accommodate motor end covers with different inner diameters. After the motor end cover is fitted, the hydraulic cylinder 301 is activated, causing the transmission block 304 to drive the connecting frame 305 to descend. The fixing plate 308 can be rotated by the drive motor 307, thereby adjusting the position of the fixing plate 308 so that the other end of the fixing plate 308 is always above the motor end cover. Then, the two fixing plates 308 are pressed against the top of the motor end cover, so that the motor end cover is horizontally fitted onto the outer surface of the positioning cone 302, thus achieving the positioning of the motor end cover.

[0036] Example 2: Figure 1-5 As shown, a fixture for producing motor end caps includes:

[0037] Base 1, with a support frame 2 fixedly connected to the top of base 1;

[0038] The positioning mechanism includes a hydraulic cylinder 301 fixedly connected to the inner wall of the base 1, and a positioning cone 302 fixedly connected to the output end of the hydraulic cylinder 301 for supporting the motor end cover.

[0039] The clamping mechanism includes a drive member movably disposed on the top of the support frame 2, and a first clamping member and a second clamping member movably disposed on the outer side wall of the drive member for fixing the motor end cover.

[0040] The driving component includes a servo motor 401 fixedly connected to the inner wall of the connecting frame 305, and a forward and reverse ball screw 402 fixedly connected to the output end of the servo motor 401. The perpendicular plane of the forward and reverse ball screw 402 coincides with the perpendicular line of the through hole.

[0041] The first clamping member includes a clamping plate 403 threadedly connected to the outer wall of the forward and reverse ball screw 402, a through hole opened in the side wall of the clamping plate 403, a mounting groove 404 opened in the inner wall of the through hole, and a pulley 405 rotatably connected to the inner wall of the mounting groove 404.

[0042] The second clamping member has the same structure as the first clamping member, and the two are symmetrically arranged about the vertical plane of the forward and reverse ball screw 402. The forward and reverse ball screw 402 is rotated by the servo motor 401, which in turn drives the two clamping plates 403 to move towards or away from each other.

[0043] The clamping mechanism also includes a slide rod 406 fixedly connected to the inner side wall of the support frame 2. The clamping plate 403 is sleeved on the outer side wall of the slide rod 406 through a through hole. The outer side wall of the pulley 405 extends to the outer surface of the mounting groove 404 and abuts against the outer side wall of the slide rod 406. When the clamping plate 403 moves, the pulley 405 will roll on the outer side wall of the slide rod 406.

[0044] Once the motor end cover is positioned, the servo motor 401 is started, causing the servo motor 401 to drive the forward and reverse ball screw 402 to rotate, which in turn drives the two clamping plates 403 to move downwards, thereby clamping and fixing the motor end cover. During this process, the pulley 405 will roll on the outer wall of the slide bar 406, which not only ensures the stability of the movement of the clamping plate 403, but also reduces the wear on the slide bar 406 and improves the service life of the device. Once the motor end cover is fixed, the hydraulic cylinder 301 is started, which in turn drives the positioning cone 302 to move downwards until the positioning cone 302 separates from the motor end cover. At this point, the motor end cover can be processed.
