Description

Technical Field

[0001] This utility model relates to the field of motor housing processing technology, specifically a fixture for processing motor housings. Background Technology

[0002] In the process of machining motor housings, such as drilling or milling, it is crucial to clamp and fix the motor housing stably and properly, as this directly affects the precision and quality of the motor housing machining.

[0003] Traditional clamping devices often employ single-point or two-point clamping. However, since motor housings are subjected to significant impacts during drilling and milling, single-point or two-point clamping may be insufficient to resist the swaying and displacement of the motor housing in various directions, easily causing the motor housing to shift and resulting in decreased machining accuracy. Furthermore, existing clamping devices typically use bolts to fix the clamping plate. Since different specifications of motor housings require different specifications of clamping plates, the traditional bolt replacement method is cumbersome, requiring a significant amount of time and manpower, thus limiting the flexibility of the production line. Therefore, a fixture for motor housing machining is proposed to improve upon the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for machining motor housings. By setting up a clamping component and a quick-release component, it solves the problem that traditional clamping devices mostly use single-point or two-point clamping. Since motor housings are subjected to significant impacts during drilling and milling, single-point or two-point clamping may not be able to resist the shaking and displacement of the motor housing in various directions, which can easily cause the motor housing to shift and reduce machining accuracy. In addition, existing clamping devices generally fix the clamping plate by bolt installation. Since different specifications of motor housings require different specifications of clamping plates, the traditional bolt replacement method is cumbersome, requires a lot of time and manpower, and limits the flexibility of the production line.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a fixture for processing motor housings, including a base plate, a clamping assembly, and a quick-release assembly. The clamping assembly is disposed on the base plate and includes a first circular plate and a second circular plate. The first circular plate has four sliding grooves, and the second circular plate is equipped with four guide posts. An L-shaped plate is rotatably fitted on the guide posts, and a cylinder is rotatably fitted on the L-shaped plate. A sliding plate is mounted on the cylinder, and the sliding plate is slidably fitted with the sliding grooves. The quick-release assembly is disposed on the clamping assembly and is equipped with a clamping plate.

[0007] Furthermore, a support plate is installed at the bottom of the first circular plate, and the end of the support plate away from the first circular plate is mounted on the substrate. The bottom of the second circular plate is mounted with the power output shaft of the drive source, and the drive source is mounted on the substrate.

[0008] Furthermore, the quick-release assembly includes a connecting plate, a T-shaped plate, and a limiting post. The connecting plate is mounted on the sliding plate and has a T-shaped groove. The T-shaped plate is mounted on the bottom of the clamping plate and slides in conjunction with the T-shaped groove. Both the connecting plate and the T-shaped plate have corresponding through holes. The limiting post engages with the through holes and has a threaded limiting ring.

[0009] Furthermore, one end of the limiting post is provided with an external thread structure, and the other end of the limiting post is fixedly installed with a handle.

[0010] Furthermore, an arc-shaped groove is provided on the clamping plate, and a rubber pad is provided on the arc-shaped groove.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up a clamping assembly, starts a stepper motor, causing the power output shaft of the stepper motor to rotate, which in turn drives the second circular plate to rotate and simultaneously drives the four guide columns to rotate. The guide columns drive the L-shaped plate to rotate and simultaneously drive the cylinder to rotate. The cylinder drives the slide plate to slide in the slide groove. The slide plate drives the connecting plate and the clamping plate to move. The four clamping plates move towards the center at the same time, thereby clamping the motor housing in the arc groove. This solves the problem that traditional clamping devices mostly use single-point or two-point clamping. Since the motor housing is subjected to great impact during drilling and milling, single-point or two-point clamping may not be able to resist the shaking and displacement of the motor housing in various directions, which can easily cause the motor housing to shift and lead to a decrease in machining accuracy.

[0013] 2. The utility model, by setting a quick-release component, allows for the rapid disassembly of the clamping plate by unscrewing the limiting ring from the limiting post, pulling the limiting post out of the through hole, and finally sliding the T-shaped plate at the bottom of the clamping plate out of the T-slot. This solves the problem that existing clamping devices generally use bolts to fix the clamping plate, and since different specifications of motor housings require different specifications of clamping plates, the traditional bolt replacement method is cumbersome, consumes a lot of time and manpower, and limits the flexibility of the production line.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a jig for machining motor housing, including a base plate 1, a clamping assembly 2 and a quick-release assembly 3. The clamping assembly 2 is disposed on the base plate 1, the quick-release assembly 3 is disposed on the clamping assembly 2, and a clamping plate 4 is disposed on the quick-release assembly 3. The base plate 1 can be mounted on a machining tool as needed.

[0022] The quick-release assembly 3 includes a connecting plate 301, a T-shaped plate 303, and a limiting post 305. The connecting plate 301 is bolted to the slide plate 207. The connecting plate 301 has a T-shaped groove 302, and multiple T-shaped grooves 302 can be set according to actual needs. The T-shaped plate 303 is bolted to the bottom of the clamping plate 4. The T-shaped plate 303 and the T-shaped groove 302 slide together. The connecting plate 301 and the T-shaped plate 303 both have corresponding through holes 304. The limiting post 305 cooperates with the through holes 304. The limiting post 305 has a threaded limiting ring 306. One end of the limiting post 305 has an external thread structure, and the other end of the limiting post 305 is fixedly installed with a handle.

[0023] When quick installation of the clamping plate 4 is required, first select a suitable clamping plate 4, slide the T-shaped plate 303 at the bottom of the clamping plate 4 into the T-shaped groove 302, align the through holes 304 on the connecting plate 301 and the T-shaped plate 303, then insert the limiting post 305 into all the through holes 304 in sequence until the end of the limiting post 305 with the external thread structure passes through all the through holes 304, and at the same time, the handle of the limiting post 305 abuts against the connecting plate 301. Then screw on the limiting ring 306 to fix it, so that the clamping plate 4 can be installed quickly. When quick disassembly of the clamping plate 4 is required, first unscrew the limiting ring 306 from the limiting post 305, then pull the limiting post 305 out of the through hole 304, and finally slide the T-shaped plate 303 at the bottom of the clamping plate 4 out of the T-shaped groove 302 of the connecting plate 301, so as to realize the quick disassembly of the clamping plate 4, which is convenient for changing clamping plates 4 of different specifications according to different work requirements.

[0024] The clamping plate 4 has an arc-shaped groove 401, which can adapt to various round or near-round motor housings and has strong versatility. When clamping round or elliptical motor housings, the arc-shaped groove 401 increases the contact area. Compared with traditional flat clamping, the larger contact area can avoid deformation of the motor housing due to excessive local pressure. A rubber pad is provided on the arc-shaped groove 401. The rubber pad has good elasticity and wear resistance and can absorb some of the impact force, reducing the damage to the surface of the motor housing caused by vibration or collision during the clamping process.

[0025] The clamping assembly 2 includes a first circular plate 201 and a second circular plate 203. The first circular plate 201 has four sliding grooves 202. The second circular plate 203 is bolted with four guide posts 204. An L-shaped plate 205 is rotatably fitted on the guide posts 204. The L-shaped plate 205 has holes, and the guide posts 204 are rotatably fitted in the holes via bearings. A cylinder 206 is rotatably fitted on the L-shaped plate 205. The L-shaped plate 205 has holes, and the cylinder 206 is rotatably fitted in the holes via bearings. A sliding plate 207 is bolted to the cylinder 206, and the sliding plate 207 is slidably fitted with the sliding grooves 202.

[0026] A support plate 5 is bolted to the bottom of the first circular plate 201. The end of the support plate 5 away from the first circular plate 201 is bolted to the base plate 1. The bottom of the second circular plate 203 is connected to the power output shaft of the drive source via a coupling. The drive source can be a suitable stepper motor, which is bolted to the base plate 1.

[0027] When the motor housing needs to be clamped, the stepper motor is started by an external controller, causing the power output shaft of the stepper motor to drive the second circular plate 203 to rotate through the coupling. The second circular plate 203 drives the four guide posts 204 to rotate. The guide posts 204 drive the L-shaped plate 205 to rotate, and at the same time drive the cylinder 206 to rotate. The cylinder 206 drives the slide plate 207 to slide in the slide groove 202. The sliding of the slide plate 207 drives the connecting plate 301 and the clamping plate 4 to move. The four clamping plates 4 move towards the center at the same time, thereby clamping the motor housing in the arc groove 401. The four-corner clamping can apply force at four different positions of the motor housing, forming a stable support structure. Compared with the traditional single-point or two-point clamping, it can better resist the shaking and displacement of the motor housing in all directions.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
