Description

Technical Field

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

[0002] In the field of motor manufacturing, the processing quality of the motor housing plays a crucial role in the performance and service life of the motor. During the processing, such as drilling, milling, and grinding, the motor housing needs to be firmly fixed to ensure processing accuracy and quality.

[0003] Traditional motor housing clamping often uses flat clamping plates. The contact area between the flat clamping plate and the motor housing is small, and the clamping force is unevenly distributed, which can easily cause the motor housing to rotate or shift during processing, affecting the processing accuracy. In addition, although some clamping devices have clamping functions, they lack multi-directional fixation. The motor housing is easily shaken by external vibration, collision or processing force, resulting in processing errors and reducing product quality. Therefore, a clamping device for motor processing is proposed to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for motor processing. By setting up a clamping component and a clamping component, it solves the problems of traditional motor housing clamping, which mostly uses flat clamping plates. The contact area between the flat clamping plate and the motor housing is small and the clamping force is unevenly distributed, which makes the motor housing easy to rotate or shift during processing, affecting the processing accuracy. In addition, although some clamping devices have a clamping function, they lack multi-directional fixation. The motor housing is easily shaken by external vibration, collision or processing force, resulting in processing errors and reducing product quality.

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

[0006] This utility model is a clamping device for motor processing, including a base plate, a clamping assembly and a pressing assembly. The base plate has two T-shaped grooves. The clamping assembly is disposed on the base plate and includes a bidirectional threaded rod with two connecting plates threadedly engaged on it. A T-shaped plate is installed at the bottom of the connecting plate and slides in the T-shaped groove. A clamping plate is installed on the connecting plate and has an arc-shaped groove. The pressing assembly is disposed on the clamping assembly.

[0007] Furthermore, the clamping assembly also includes a support plate, which is mounted on the substrate. A first circular groove is formed on the support plate. One end of the bidirectional threaded rod is rotatably engaged with the first circular groove through a bearing. The other end of the bidirectional threaded rod is mounted to the power output shaft of the drive source. The drive source is mounted on the substrate. The bottom of the clamping plate is slidably attached to the surface of the substrate.

[0008] Furthermore, the clamping assembly includes a connecting frame and a threaded rod. The connecting frame is mounted on the clamping plate and has a through hole and a second circular groove. The power output shaft of the drive source passes through the through hole and is installed at one end of the threaded rod. The other end of the threaded rod is rotatably engaged with the second circular groove through a bearing. A cross plate is threaded onto the threaded rod, and a pressure plate is mounted on the cross plate.

[0009] Furthermore, grooves are provided on both sides of the connecting frame, and two sliding plates are installed on the horizontal plate, which slide in conjunction with the grooves.

[0010] Furthermore, the pressure plate is designed in an arc shape.

[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 drive a bidirectional threaded rod to rotate. The bidirectional threaded rod drives two connecting plates to move in opposite directions simultaneously, causing the connecting plates to clamp the motor housing with the arc-shaped groove on the clamping plate. This solves the problem that traditional motor housing clamping often uses flat clamping plates, which have a small contact area with the motor housing, uneven clamping force distribution, and are prone to causing the motor housing to rotate or shift during processing, affecting processing accuracy.

[0013] 2. This utility model, by setting up a clamping component, uses a servo motor to drive the power output shaft of the servo motor to rotate the threaded rod. The threaded rod moves the horizontal plate downwards, which in turn moves the pressure plate downwards until the pressure plate clamps the motor housing. By combining the clamping component and the clamping component, this invention solves the problem that some clamping devices, although having a clamping function, lack multi-directional fixation, and the motor housing is prone to shaking due to external vibration, collision, or processing force, resulting in processing errors and reduced product quality.

[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

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a clamping device for motor processing, including a base plate 1, a clamping assembly 2 and a clamping assembly 3. The clamping assembly 2 is disposed on the base plate 1, and the clamping assembly 3 is disposed on the clamping assembly 2. A support leg is fixedly installed at the bottom of the base plate 1. The support leg is used to support the entire clamping device and prevent the device from tilting or shaking due to external collisions. Two T-shaped grooves 101 are opened on the base plate 1. The T-shaped grooves 101 not only provide guidance for the movement of the connecting plate 202, but also prevent the connecting plate 202 from detaching from the base plate 1 during movement, thus ensuring the stability of the clamping assembly 2 during operation.

[0023] The clamping assembly 2 includes a bidirectional threaded rod 201, on which two connecting plates 202 are threadedly engaged. A T-shaped plate 203 is bolted to the bottom of the connecting plate 202, and the T-shaped plate 203 is slidably engaged with the T-shaped groove 101. A clamping plate 204 is fixedly mounted on the connecting plate 202, and an arc-shaped groove 205 is provided on the clamping plate 204. The arc-shaped groove 205 can better fit the shape of the motor housing, increase the contact area with the motor housing, thereby improving the clamping stability and preventing the motor housing from rotating or displacing during processing.

[0024] The clamping assembly 2 also includes a support plate 206, which is bolted to the base plate 1. The support plate 206 has a first circular groove 207. One end of the bidirectional threaded rod 201 is rotatably engaged with the first circular groove 207 through a bearing. The outer ring of the bearing is fixedly installed in the first circular groove 207, and the inner ring of the bearing is rotatably engaged with one end of the bidirectional threaded rod 201. The other end of the bidirectional threaded rod 201 is installed with the power output shaft of the drive source through a coupling. The drive source can be a suitable stepper motor, which is bolted to the base plate 1. The bottom of the clamping plate 204 slides against the surface of the base plate 1.

[0025] When the motor housing needs to be clamped, the power output shaft of the stepper motor is driven to rotate by an external controller. The power output shaft of the stepper motor drives the bidirectional threaded rod 201 to rotate. The bidirectional threaded rod 201 drives the two connecting plates 202 to move towards each other at the same time, so that the two connecting plates 202 move closer to each other. The connecting plates 202 drive the T-shaped plate 203 to slide in the T-shaped groove 101. The connecting plates 202 drive the clamping plate 204 to move, so that the arc groove 205 on the clamping plate 204 gradually moves closer to the motor housing until the two arc grooves 205 clamp the motor housing.

[0026] The clamping assembly 3 includes a connecting frame 301 and a threaded rod 304. The connecting frame 301 is bolted to the clamping plate 204. The connecting frame 301 has a through hole 302 and a second circular groove 303. The power output shaft of the drive source passes through the through hole 302 and is installed with one end of the threaded rod 304 through a coupling. The drive source can be a suitable servo motor. The servo motor is bolted to the connecting frame 301. The other end of the threaded rod 304 is rotatably engaged with the second circular groove 303 through a bearing. The outer ring of the bearing is fixedly installed in the second circular groove 303, and the inner ring of the bearing is rotatably engaged with the other end of the threaded rod 304. A horizontal plate 305 is threaded onto the threaded rod 304, and a pressure plate 306 is fixedly installed on the horizontal plate 305.

[0027] Both sides of the connecting frame 301 are provided with sliding grooves 307. Two sliding plates 308 are fixedly installed on the horizontal plate 305. The sliding plates 308 slide in the sliding grooves 307. The sliding grooves 307 can guide the sliding plates 308, preventing the sliding plates 308 and the horizontal plate 305 from shifting during the up and down movement. This ensures that the pressure plate 306 can vertically press the motor housing, preventing the pressure plate 306 from tilting and affecting the pressing effect.

[0028] The pressure plate 306 is arc-shaped. The arc shape can better fit the surface of the motor housing, increase the contact area with the motor housing, and make the clamping force more evenly distributed on the motor housing. This prevents excessive local pressure from damaging the motor housing and also improves the stability of clamping.

[0029] When it is necessary to press the motor housing, the power output shaft of the servo motor is driven to rotate by an external controller. The power output shaft of the servo motor drives the threaded rod 304 to rotate through the coupling. The threaded rod 304 drives the horizontal plate 305 to move downward. The horizontal plate 305 drives the slide plate 308 to slide downward in the slide groove 307. The horizontal plate 305 drives the pressure plate 306 to move downward until the pressure plate 306 is in contact with the surface of the motor housing, thereby pressing the motor housing.

[0030] The clamping device combines the clamping component 2 and the clamping component 3, which can fix the motor housing in multiple directions, improve the stability of the motor housing during the processing, reduce processing errors caused by the shaking of the motor housing, and ensure processing quality.
