Description

Technical Field

[0001] This utility model relates to the field of bearing processing, and more specifically, to a bearing processing end face device. Background Technology

[0002] In the bearing manufacturing industry, end face chamfering is a key process to ensure bearing assembly accuracy and service life. Traditional manual chamfering operations suffer from problems such as low efficiency, poor consistency of chamfer angles, and large fluctuations in product qualification rates. In particular, it is difficult to meet the stringent requirements of modern industry for bearing end face geometric accuracy (such as chamfer symmetry and surface roughness) in mass production scenarios.

[0003] Although existing semi-automatic chamfering equipment has partially replaced manual labor, it still generally relies on the operator's experience in the bearing clamping and positioning process. Frequent manual adjustment of the fixture not only increases auxiliary time, but may also cause deformation of the bearing raceway due to improper clamping force control. Utility Model Content

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: A bearing end face processing device includes an end face chamfering mounting table, an automatic processing positioning component is provided on one side of the end face chamfering mounting table, a bearing placement component is provided on one side of the automatic processing positioning component, and a chamfering mounting component is provided on one side of the bearing placement component. To achieve automatic positioning during processing, the automatic positioning component includes a drive motor, which is installed inside the end face chamfering mounting platform. The output end of the drive motor is connected to a bearing fixing plate, and a positioning rod is connected around the bottom of the bearing fixing plate. A positioning plate is provided on one side of the positioning rod, and a trigger switch is installed inside the positioning plate. A positioning electric push rod is connected to the bottom of the positioning plate, and a locking electric push rod is provided on one side of the positioning electric push rod. A locking frame is connected to the output end of the locking electric push rod, and the locking frame locks into the positioning rod.

[0006] Furthermore, the positioning electric actuator and the engaging electric actuator are respectively installed above the end face chamfering mounting platform.

[0007] Furthermore, a controller is installed on one side of the end face chamfering mounting platform, and the drive motor, positioning electric push rod, and locking electric push rod are electrically connected to the controller.

[0008] Furthermore, in order to achieve the function of bearing placement, the bearing placement assembly includes a bearing placement groove, which is opened around the inside of the end face chamfered mounting platform. A bearing fixing arc plate is symmetrically connected to the outside of the bearing placement groove. A sliding rod is connected to one side of the bearing fixing arc plate. A sliding rod limiting plate is slidably fitted around the sliding rod. A thrust spring is connected between the bearing fixing arc plate and the sliding rod limiting plate.

[0009] Furthermore, the sliding rod limiting plate is connected to the positioning plate.

[0010] Furthermore, in order to achieve the chamfering effect, the chamfering mounting assembly includes a chamfering mounting bracket, which is mounted above the end face chamfering mounting platform. A chamfering electric push rod is installed inside the chamfering mounting bracket, and a motor mounting bracket is connected to the output end of the chamfering electric push rod.

In actual use, by processing the automatic positioning component, it solves the problem that although the existing semi-automatic chamfering equipment has partially replaced manual labor, it still generally relies on the operator's experience in the bearing clamping and positioning process. Frequent manual adjustment of the fixture not only increases the auxiliary time, but may also cause the bearing groove to deform due to improper clamping force control.

[0013] (2) In actual use, after precise positioning is completed, the chamfering process begins. The controller commands to cut off the drive motor constraint and start the chamfering motor. The chamfering electric push rod begins to press down along the height direction of the end face chamfering mounting table. At this time, the chamfering limit rod is limited to feed along the straight hole trajectory that is slidably fixed to the chamfering mounting bracket. The chamfering motor synchronously drives the chamfering grinding head to rotate at high speed, so that it moves down at a uniform speed to contact the end of the bearing to be chamfered and produce a continuous grinding effect.

[0017] 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.

[0018] According to an embodiment of the present invention, a bearing processing end face device is provided, including an end face chamfering mounting table 1, an automatic processing positioning component 2 is provided on one side of the end face chamfering mounting table 1, a bearing placement component 3 is provided on one side of the automatic processing positioning component 2, and a chamfering mounting component 4 is provided on one side of the bearing placement component 3.

[0019] like Figure 1-4As shown, according to the bearing processing end face device of this utility model embodiment, the automatic positioning component 2 includes a drive motor 201, which is installed inside the end face chamfering mounting platform 1. The output end of the drive motor 201 is connected to a bearing fixing plate 202. A positioning rod 203 is connected around the bottom of the bearing fixing plate 202. A positioning plate 204 is provided on one side of the positioning rod 203. A trigger switch 205 is installed inside the positioning plate 204. A positioning electric push rod 206 is connected to the bottom of the positioning plate 204. A locking electric push rod 207 is provided on one side of the positioning electric push rod 206. A locking frame 208 is connected to the output end of the locking electric push rod 207. The locking frame 208 locks with the positioning rod 203. The positioning electric push rod 206 and the locking electric push rod 207 are respectively installed above the end face chamfering mounting platform 1. A controller 5 is installed on one side of the end face chamfering mounting platform 1. The drive motor 201, the positioning electric push rod 206, and the locking electric push rod 207 are electrically connected to the controller 5.

[0020] Through the above technical solution, the end face chamfering mounting platform 1 serves as the basic platform, and its core functions are achieved collaboratively by the automatic machining positioning component 2, the bearing placement component 3, and the chamfering mounting component 4. During operation, the bearing to be processed is first placed in the bearing placement groove 301. At this time, the outer ring of the bearing is fixed by a pair of symmetrically arranged bearing fixing arc plates 302 through pre-clamping force. The sliding rod 303 retracts under the guidance of the sliding rod limiting plate 304, compressing the thrust spring 305, forming a floating adaptive positioning. The automatic machining positioning component 2 then activates: the positioning electric push rod 206 drives the positioning plate 204 to approach the bearing fixing plate 202. When the trigger switch 205 built into the positioning plate 204 contacts the bearing edge, the positioning displacement signal triggers the locking electric push rod 207 to operate through the controller 5. The locking frame 208 then extends, forming a rigid locking with the circumferentially distributed positioning rods 203, simultaneously triggering the drive motor 201 to start operating.

[0021] like Figure 1-4 As shown, according to the bearing processing end face device of this utility model embodiment, the bearing placement assembly 3 includes a bearing placement groove 301, which is formed around the inside of the end face chamfering mounting platform 1. A bearing fixing arc plate 302 is symmetrically connected to the outer periphery of the bearing placement groove 301. A sliding rod 303 is connected to one side of the bearing fixing arc plate 302. A sliding rod limiting plate 304 is slidably fitted around the sliding rod 303. The sliding rod limiting plate 304 is connected to the end face chamfering mounting platform 1. A thrust spring 305 is connected between the bearing fixing arc plate 302 and the sliding rod limiting plate 304. The sliding rod limiting plate 304 is connected to the positioning plate 204.

[0022] Through the above technical solution, the bearing fixation during the positioning process is guaranteed by dual constraints: axial constraint is achieved by the precise positioning reference surface of the positioning plate 204, while radial constraint relies on the elastic preload design of the bearing placement assembly 3. The thrust spring 305 generates radial pressure on the bearing through the bearing fixing arc plate 302, ensuring that the bearing is always in close contact with the reference inner wall of the bearing placement groove 301. The sliding rod limiting plate 304 is rigidly fixed to the end face chamfered mounting platform 1 and directly connected to the positioning plate 204. During the advancement of the positioning electric push rod 206, the sliding rod 303 is pulled synchronously, so that the entire bearing pre-clamping state is dynamically synchronized with the precise position of the positioning plate 204. Subsequently, the locking frame 208 locks the circumferentially arranged positioning rods 203, and the drive motor 201 can drive the bearing fixing plate 202 to rotate, ensuring that the linkage zero position error is maintained. The positioning signal is managed by the trigger switch 205 through the controller 5, which manages the start, stop, and lock logic of the locking electric push rod 207 and the drive motor 201.

[0023] like Figure 1-4 As shown, according to an embodiment of the present invention, the bearing processing end face device includes a chamfering mounting assembly 4, which is mounted on the end face chamfering mounting platform 1. A chamfering electric push rod 402 is installed inside the chamfering mounting frame 401. A motor mounting frame 403 is connected to the output end of the chamfering electric push rod 402. A chamfering limiting rod 404 is connected above the motor mounting frame 403. The chamfering limiting rod 404 is slidably engaged with the chamfering mounting frame 401. A chamfering motor 405 is mounted at the bottom of the motor mounting frame 403. A chamfering grinding head 406 is connected to the output end of the chamfering motor 405. The chamfering motor 405 is electrically connected to the controller 5.

[0024] After precise positioning is achieved using the above technical solution, the chamfering process begins. Controller 5 instructs the drive motor 201 to cut off its constraint and starts the chamfering motor 405. The chamfering electric push rod 402 begins to press down along the height direction of the end face chamfering mounting table 1. At this time, the chamfering limit rod 404 is limited to feed along the straight hole trajectory slidably fixed to the chamfering mounting bracket 401. The chamfering motor 405 synchronously drives the chamfering grinding head 406 to rotate at high speed, causing it to move down at a uniform speed to contact the end of the bearing to be chamfered and produce a continuous grinding effect. After processing, the chamfering electric push rod 402 drives the chamfering motor 405 and the motor mounting bracket 403 to rise to the predetermined exit high position. Controller 5 decouples the locking mechanism, releasing the locking of the locking bracket 208 and returning it to the positioning rod position 203. The positioning and bearing placement components complete their electrical control actions, releasing all cylinder components and restoring them to the standby state. The control loop is integrated with the drive system through the controller 5. Each actuator must be individually and correctly connected to the control box via a clear electrical connection.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
