[0002] In the field of bearing manufacturing, the machining accuracy of both end faces directly affects the assembly quality and performance of the bearing. Grinding is a core process that ensures key indicators such as end face flatness and perpendicularity. With the rapid development of the machinery industry, the requirements for bearing machining efficiency and precision are increasing.

In addition, during the grinding process, the bearing can only rotate relative to the turntable and the grinding device, and the bearing cannot rotate on its own. The two end faces of the bearing do not rotate sufficiently relative to the grinding device, which makes the grinding effect of the end faces relatively poor, thereby affecting the subsequent grinding of the bearing.

[0023] In one embodiment of the present invention, the limiting pressure plate 9 includes: a supporting base plate 30, a pressure plate 31, an arc-shaped portion 28 and a rack 29, wherein the supporting base plate 30 is connected to the groove 32, the groove 32 is centrally opened on the surface of the device body 1, the pressure plate 31 is fixedly set on the supporting base plate 30, the arc-shaped portion 28 is opened on one side surface of the pressure plate 31, and the rack 29 is distributed along the surface of the arc-shaped portion 28.

[0025] In one embodiment of the present invention, an adaptive clamping cavity 27 is further provided at the bottom of the material trough 10, and the adaptive clamping cavity 27 is provided with: a clamping roller 23 and a support plate 26, wherein the support plate 26 is fixedly arranged on the inner bottom surface of the adaptive clamping cavity 27, and the clamping roller 23 is symmetrically arranged on the support plate 26 and is located on both sides of the bottom of the material trough 10, and the clamping roller 23 and the roller 17 are rubber rollers with anti-slip grooves on the surface, and the clamping roller 23 is connected to a telescopic rod 25, which is fixedly arranged on the support plate 26, and the telescopic rod 25 is connected to a compression spring 24.

[0026] In one embodiment of the present invention, buffer portions are provided at both the upper and lower ends of the arc portion 28 , and the buffer portions are arc-shaped rounded structures.

[0027] In one embodiment of the present invention, the thickness of the pressing plate 31 is smaller than the thickness of the feeding turntable 7 .

[0028] Specifically, when batch processing is performed on both ends of the bearing, the relevant personnel first adjusts the position of the grinding device 2 according to the processing requirements, and then turns on the grinding device 2 to drive the grinding disc 3 to rotate in preparation for grinding. Then the relevant personnel turns on the driving device to drive the feed turntable 7 to rotate, and then places the bearings to be processed one by one into the material trough 10 in the feed turntable 7, so that the feed turntable 7 rotates to feed the bearings to be processed between the two grinding devices 2, and a processing area is formed between the two grinding discs 3. The passive clamping component 11 provided on each material trough 10 can cooperate with the limiting pressure plate 9 provided in the groove 32 to clamp and fix the bearings to be processed in the corresponding material trough 10 when the feed turntable 7 rotates into the processing area, so as to ensure the stability of the end faces on both sides during the grinding process and avoid affecting the end face processing due to looseness.

[0029] When both ends of each bearing to be processed placed in the trough 10 run to the processing area, the passive pressing assembly 11 provided on the trough 10 can move under the drive of the limit pressure plate 9, wherein the limit pressure plate 9 will first contact the driving gear 12 (such as Figure 10 As shown), at this time, the driving gear 12 receives the extrusion force and applies downward pressure to the clamping rod 15 through the gear seat 13, so that the clamping rod 15 slides downward on the packaging plate 18, thereby pressing the roller mounting seat 16 installed at the end of the clamping rod 15 downward, so that the two rollers 17 symmetrically installed on the roller mounting seat 16 press down and fix the two ends of the bearing to be processed placed in the material trough 10, so that it maintains a stable posture when entering the processing area, so that the grinding sheets 3 on both sides can grind the two end surfaces of the bearing.

[0030] It should be noted that the packaging plate 18 closes the opening of the material trough 10 and is fixed to the surface of the feed turntable 7 by bolts. Relevant personnel can remove the passive clamping assembly 11 for maintenance by removing the bolts, which makes maintenance simple and convenient.

[0031] Specifically, during the coordinated movement of the passive pressing assembly 11 and the limiting pressure plate 9 , the driving gear 12 rotates along the rack 29 provided on the surface of the arc-shaped portion 28 , thereby driving the roller 17 to rotate under the transmission of the transmission assembly 22 .

[0032] Among them, as the driving gear 12 rotates, the gear toothed disc 19 connected thereto drives the transmission toothed disc 20 to rotate through a chain transmission, and then the transmission toothed disc 20 drives the rolling toothed discs 21 distributed on both sides thereof to rotate through the chain, thereby rotating the rollers 17 symmetrically mounted on the roller mounting seat 16. At this time, the rollers 17 on the roller mounting seat 16 apply downward rolling pressure to both ends of the bearing to be processed, clamping both ends of the bearing while driving it to rotate, thereby further increasing the grinding effect of the grinding sheet on its end face; When the limiting pressure plate 9 cooperates with the passive clamping assembly 11 to clamp the bearing to be processed, the supporting base plate 30 arranged on the groove 32 provides support for the pressure plate 31, so that the arc portion 28 opened on one side of the pressure plate 31 is docked with the passive clamping assembly 11 on each material trough 10, and the passive clamping assembly 11 rotated to the processing area is pressurized by the arc portion 28. At this time, the arc portion 28 applies downward pressure to the driving gear 12 and drives it to rotate through the engagement of the rack 29 with the driving gear 12. When the passive clamping assembly 11 leaves the processing area, the pressure plate 31 is separated from the passive clamping assembly 11. In the state without extrusion force, the driving gear 12 can drive the entire assembly to reset under the support of the reset spring 14, thereby releasing the clamped and fixed processed bearing.

[0033] It should be noted that buffer portions (not shown in the figure) are provided at both ends of the arc-shaped portion 28. The buffer portion is an arc-shaped rounded structure. By providing the rounded buffer portion, gradual pressure can be achieved through the rounded surface when the driving gear 12 rotates to the working area, thereby avoiding structural damage caused by direct hard collision.

[0034] In order to further realize the self-rotation of the bearing during processing, an adaptive clamping cavity 27 can be set at the bottom of the material trough 10, and two symmetrical clamping rollers 23 with a certain elastic contraction function can be set therein. When the passive clamping component 11 presses down on both ends of the bearing to be processed, the two symmetrically arranged clamping rollers 23 can provide elastic rolling support for the bottom of the bearing to be processed, so that the bearing can rotate better during processing, thereby increasing the contact effect of its end face larger than the grinding sheet 3, and having a better grinding effect.

[0035] It should be noted that the clamping roller 23 is elastically supported by a telescopic rod 25 equipped with a compression spring 24, and provides stable support in the adaptive clamping cavity 27 through the support plate 26. It can achieve relatively stable elastic clamping of the bearing to be processed, and at the same time, it can clamp bearings of different sizes according to its own telescopic cooperation with the passive clamping component 11, so that it can be expanded and contracted according to the size of the bearing, making it more flexible and versatile to use and having a wider range of applications.

[0036] In one embodiment of the present invention, the clamping roller 23 and the roller can be made of rubber material, which can increase the contact effect with the metal surface of the bearing, increase friction, and make the metal easier to realize automatic movement.

[0037] Specifically, relevant personnel can control the position of the grinding device 2 and the operation of the grinding sheet 3 through the controller, and can also control the start and stop of the driving device to ensure the normal operation of the entire equipment.

[0038] It should be noted that the control method of this application can be automatically controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0039] In summary, the present invention provides a double-end surface grinding device for bearing processing, which rotates the bearing to be processed and feeds it between the grinding sheets for double-end surface grinding through a feed turntable with multiple material troughs, and the loading is convenient and fast; a passive clamping component is set in each material trough, and when the bearing in the material trough moves to the grinding area, the limit pressure plate cooperates with the passive clamping component to apply downward pressure to the driving gear and thus press the bearing to be processed into the material trough, thereby ensuring its stability during the grinding process and avoiding the end face shaking caused by loose clamping and affecting the grinding effect of the end face; before entering the grinding area, there is ample space in the material trough, which is convenient for placing the bearing, and the bearing to be processed can be directly placed until it enters the grinding area, and the automatic clamping of the bearing to be processed can be realized after entering the grinding area. When leaving the grinding area, the passive clamping component is disengaged from the contact with the limit pressure plate, and the passive clamping component can be reset, so that The loosened bearing after grinding is easy to remove, which brings convenience to the processing process; through the transmission assembly arranged on the passive clamping assembly and the clamping roller in the material trough, the driving gear can be squeezed by the pressure plate, and the gear tooth plate can be driven by the meshing transmission of the rack and the driving gear through the chain drive to drive the transmission tooth plate and drive the rolling tooth plate, so that the roller and the clamping roller on the roller mounting seat can achieve a rolling clamping effect on the bearing, clamping the bearing while driving it to rotate, thereby further increasing the grinding effect of the grinding sheet on its end face; the clamping roller arranged in the material trough is elastically supported by a telescopic rod equipped with a compression spring, which can achieve relatively stable elastic clamping of the bearing to be processed, and can achieve clamping of bearings of different sizes according to its own telescopic cooperation with the passive clamping assembly, which is more flexible and versatile to use and has a wider range of applications.
