Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring clamping, in particular to a bearing ring grinding and clamping device. Background Art

[0002] Grinding and clamping bearing rings are crucial steps in the bearing ring processing process. Grinding and clamping bearing rings are crucial for ensuring machining accuracy, improving production efficiency, and ensuring product quality. Precise clamping ensures that the bearing rings maintain a stable position during the grinding process, avoiding errors and ensuring that the finished bearing rings meet design requirements.

[0003] The utility model with announcement number CN219075604U discloses a bearing ring clamp that is easy to clamp. It is equipped with a fixed seat, a limit rod, a clamping plate, a slide plate, a mounting seat, a screw, a turntable and a bearing seat, and the rotation of the screw is controlled by the turntable, so that the slide plate cooperates with the clamping plate and the fixed seat to clamp the bearing ring. It has a simple structure, is easy to manufacture, and is conducive to cost savings.

[0004] However, the above-mentioned clamp can only play a fixing role by clamping the outer wall of the bearing ring. When the outer wall of the bearing ring needs to be processed, the above-mentioned clamp cannot cooperate because the above-mentioned clamp will block the outer wall of the bearing ring when clamping, making it impossible to carry out the grinding work. In addition, the above-mentioned device can only play a stable and reliable clamping role for bearing rings of specific sizes. When the size of the bearing ring changes, the clamping effect will be poor due to the size mismatch. Therefore, a bearing ring grinding and clamping device is proposed to address the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a bearing ring grinding and clamping device, which can drive the two transmission slides through a screw drive mechanism, and then drive the arc clamping plates to approach or move away synchronously. When it is necessary to clamp the outer wall of the bearing ring, the two arc clamping plates are brought closer together synchronously to achieve clamping and fixation. When it is necessary to clamp the inner wall of the bearing ring, the two arc clamping plates are moved away synchronously to press against the inner wall of the bearing ring to achieve clamping and fixation, which can meet different grinding requirements. In addition, the arc clamping plates and the transmission slides are detachably connected, so by replacing the matching arc clamping plates according to the size of the bearing to be clamped, it can ensure that bearing rings of different sizes are stably clamped, which solves the technical problems in the prior art that it is difficult for the clamp to freely change the clamping method, which brings inconvenience to grinding, and when the size of the bearing ring changes, the clamping effect is poor due to size mismatch.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] The cam is adapted to move the two guide rails together so that the cam can move relative to the bearing ring and thereby enable the cam to move relative to the bearing ring.

[0008] In one possible implementation, the transmission slider includes a sliding block, and anti-slip end plates and transmission blocks are fixedly provided at the upper and lower ends thereof, respectively. The anti-slip end plates and the transmission block can play a role of clamping and limiting the sliding block to prevent the transmission slider from falling out of the composite slide groove as a whole. A through threaded hole is provided on the transmission block. The above structural form provides the necessary structural basis for the screw drive mechanism and its transmission connection.

[0009] In one possible implementation, the screw drive mechanism includes a central connecting piece fixedly arranged in the middle of the lower end surface of the clamp plate, on which a bidirectional screw is rotatably connected, and both ends of the bidirectional screw pass through the bottom cover plate and are rotatably connected thereto. This structural form can realize the installation and fixation of the bidirectional screw, and at the same time, the two ends of the bidirectional screw are respectively threadedly connected to the corresponding transmission blocks. When the bidirectional screw rotates, it can drive the transmission block threaded thereto to move.

[0010] In one possible implementation, threads are provided at both ends of the bidirectional screw rod, and the directions of the two sets of threads are opposite. This type of thread arrangement can drive the transmission sliders connected on both sides to run in opposite directions when the bidirectional screw rod rotates, that is, the transmission sliders can move closer or farther away synchronously. In addition, an adjustment handwheel is fixedly connected to the end of the bidirectional screw rod, and this structure can facilitate the user to twist the bidirectional screw rod.

[0011] In one possible implementation, the anti-slip end plate and the sliding block are provided with connecting plug-in grooves, and the arc-shaped clamping plate includes a plug-in block that matches the size of the plug-in groove. This connection method can facilitate the replacement of the entire arc clamping plate. The plug-in block is fixedly connected to the arc plate, and rubber gaskets are attached to the inner and outer sides of the arc plate. The arc plate can ensure a larger contact area with the bearing ring to ensure the clamping and fixing effect, and the rubber gasket can increase the friction with the bearing ring to improve the fixing effect. In addition, the arc plate and the anti-slip end plate are fixedly connected by connecting bolts. This scheme can achieve fixed installation of the entire arc clamping plate.

[0012] In one possible implementation, the cross-section of the rubber gasket is trapezoidal, and the length of the upper base of the trapezoid is greater than the length of the lower base. At the same time, the outer surface of the rubber gasket is provided with granular protrusions. The above-mentioned structural form can strengthen the restraining effect of the rubber gasket on the bearing ring and prevent the rubber gasket from falling off the arc-shaped splint due to sliding.

[0013] In one possible implementation, the composite slide includes a main slide and a sinking slide opened on its upper side, wherein the groove width of the main slide is consistent with the width of the sliding block, and the groove width of the sinking slide is consistent with the diameter of the anti-slip end plate. The above structural form provides the necessary structural basis for the sliding connection between the transmission slider and the composite slide.

[0014] In a possible implementation, a plurality of symmetrical mounting ears are fixedly provided on the bottom of the bottom cover plate, and through mounting holes are provided on the mounting ears. This structural form can facilitate the installation and fixation of the entire clamping device.

[0015] In one possible implementation, a plurality of symmetrically arranged guide rail plates are fixedly provided on the lower end surface of the clamp plate, and the spacing between the guide rail plates matches the width of the transmission block. The setting of the guide rail plates can make the transmission block more stable during the sliding process, so that the arc-shaped clamp plate as a whole will not shake or deflect when moving.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] The two transmission slides are driven to move synchronously closer or farther away through the screw drive mechanism, thereby driving the two arc-shaped clamping plates installed thereon to move synchronously closer or farther away. When the outer wall of the bearing ring needs to be clamped, the two arc-shaped clamping plates are moved closer synchronously to achieve clamping and fixing. When the inner wall of the bearing ring needs to be clamped, the two arc-shaped clamping plates are moved away synchronously to press against the inner wall of the bearing ring to achieve clamping and fixing, which can meet different grinding requirements.

[0018] In addition, the arc-shaped clamping plate and the transmission slider are detachably connected, so by replacing the matching arc-shaped clamping plate according to the size of the bearing to be clamped, it can ensure that bearing rings of different sizes are stably clamped.

[0025] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0026] like Figure 1 - Figure 2 When the cam 2 is in the working state, the cam 2 is in the working state, and the cam 2 is in the working state, so the cam 2 is in the working state, and the cam 2 is in the working state, so the cam 2 is in the working state, and the cam 2 is in the working state, so the cam 2 is in the working state, and the cam 2 is in the working state, so the cam 2 is in the working state, and the cam 2 is in the working state, so the cam 2 is in the working state, and the cam 2 is in the working state.

[0027] like Figure 3 As shown, the transmission slider 3 includes a sliding block 31, and anti-slip end plates 33 and a transmission block 32 are fixedly provided at the upper and lower ends thereof. The anti-slip end plates 33 and the transmission block 32 can play a role of clamping and limiting the sliding block 31 to prevent the transmission slider 3 from falling out of the composite slide 2 as a whole. A through threaded hole is provided on the transmission block 32. The above structural form provides the necessary structural basis for the screw drive mechanism 5 to be connected to its transmission.

[0028] like Figure 2 、 Figure 4As shown, the screw drive mechanism 5 includes a central connecting piece 51 fixedly arranged in the middle of the lower end surface of the clamp plate 1, on which a bidirectional screw 52 is rotatably connected, and both ends of the bidirectional screw 52 pass through the bottom cover plate 6 and are rotatably connected thereto. This structural form can realize the installation and fixation of the bidirectional screw 52, ​​and at the same time, the two ends of the bidirectional screw 52 are respectively threadedly connected to the corresponding transmission block 32. When the bidirectional screw 52 rotates, it can drive the transmission block 32 threadedly connected thereto to move; wherein, both ends of the bidirectional screw 52 are provided with threads, and the directions of the two sets of threads are opposite. This thread setting form can drive the transmission sliders 3 connected on both sides to run in reverse when the bidirectional screw 52 rotates, that is, the transmission sliders 3 are synchronously approached or synchronously moved away. In addition, the ends of the bidirectional screw 52 are fixedly connected to the adjusting handwheel 53. This structure can facilitate the user to twist the bidirectional screw 52.

[0029] like Figure 3 As shown, a connecting plug-in groove 34 is provided on the anti-slip end plate 33 and the sliding block 31, and the arc-shaped splint 4 includes a plug-in block 41 that matches the size of the plug-in groove 34. This connection method can facilitate the replacement of the arc-shaped splint 4 as a whole. An arc plate 42 is fixedly connected to the plug-in block 41, and rubber gaskets 43 are affixed to the inner and outer sides of the arc plate 42. The arc plate 42 can ensure a larger contact area with the bearing ring to ensure the clamping and fixing effect, while the rubber gasket 43 can increase the friction with the bearing ring and improve the fixing effect. In addition, the arc plate 42 and the anti-slip end plate 33 are fixedly connected by connecting bolts 44. This scheme can achieve the fixed installation of the arc splint 4 as a whole.

[0030] Among them, the cross-section of the rubber gasket 43 is a trapezoid, and the upper base length of the trapezoid is greater than the lower base length. At the same time, the outer surface of the rubber gasket 43 is provided with granular protrusions. The above structural form can strengthen the restraining effect of the rubber gasket 43 on the bearing ring and prevent the rubber gasket 43 from falling off from the arc-shaped splint 4 due to sliding.

[0031] like Figure 2 As shown, the composite chute 2 includes a main chute 21 and a sinking chute 22 opened on its upper side, wherein the groove width of the main chute 21 is consistent with the width of the sliding block 31, and the groove width of the sinking chute 22 is consistent with the diameter of the anti-slip end plate 33. The above structural form provides the necessary structural basis for the sliding connection between the transmission slider 3 and the composite chute 2.

This structural form can facilitate the installation and fixation of the entire clamping device.

[0033] like Figure 4As shown, a plurality of symmetrically arranged guide rail plates 11 are fixedly provided on the lower end surface of the clamp plate 1, and the spacing between the guide rail plates 11 matches the width of the transmission block 32. The setting of the guide rail plates 11 can make the transmission block 32 more stable during the sliding process, so that the arc-shaped clamping plate 4 as a whole will not shake or deflect when moving.

[0034] The use principle and use process of this utility model:

[0035] The two transmission slides 3 are driven to approach or move away synchronously through the screw drive mechanism 5, thereby driving the two arc clamping plates 4 installed thereon to approach or move away synchronously. When it is necessary to clamp the outer wall of the bearing ring, the two arc clamping plates 4 are brought close to each other synchronously to achieve clamping and fixing. When it is necessary to clamp the inner wall of the bearing ring, the two arc clamping plates 4 are moved away synchronously to press against the inner wall of the bearing ring to achieve clamping and fixing, which can meet different grinding requirements.

[0036] The above scheme is specifically manifested as driving the bidirectional screw 52 to rotate by adjusting the hand wheel 53 to drive the transmission sliders 3 connected on both sides to run in the opposite direction, that is, to achieve synchronous approach or synchronous distance of the transmission sliders 3, so that the arc plate 42 is close to the bearing ring to be clamped and fixed, so as to achieve clamping and fixing of its inner wall or outer wall.

[0037] In addition, the arc-shaped clamping plate 4 is detachably connected to the transmission slider 3. Therefore, by replacing the matching arc-shaped clamping plate 4 according to the size of the bearing to be clamped, it can be ensured that the bearing rings of different sizes are stably clamped. During installation, the plug-in block 41 is inserted into the plug-in groove 34, and then the arc plate 42 is fixedly connected to the anti-slip end plate 33 with the connecting bolt 44 to achieve the installation and fixation of the arc-shaped clamping plate 4. When it needs to be disassembled, the above steps can be reversed.

[0038] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
