Description

Technical Field

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

[0002] Both the inner and outer walls of the bearing race need to be ground. Grinding the inner and outer walls is a necessary step in the manufacturing process of the bearing race to ensure its precision and performance. To improve the stability of the bearing race during grinding, a positioning device is used to fix it in place.

[0003] Chinese Utility Model Announcement No. CN222003355U includes a worktable with a first equipment groove on its upper surface. The beneficial effect of this utility model is that the bearing inner ring is placed between four first fixed plates and four second fixed plates. By rotating the first wheel, corresponding two first fixed plates are moved away from each other, thus supporting the bearing inner ring and restricting its rotation. The equipment can position the bearing inner ring. By rotating the second wheel, the assembly block moves downwards on the screw, causing the four second fixed plates to move towards the center of the worktable. The four converging second fixed plates can clamp and fix the bearing outer ring, thus fixing the bearing outer ring. By fixing the bearing outer and inner rings, the equipment prevents the bearing from rotating during processing, improving the quality and efficiency of bearing processing.

[0004] The applicant discovered some shortcomings in the use of the patent: threaded holes are provided on the first and second moving blocks, and bolts are provided at the bottom of the first and second fixing plates. The fixing is achieved by screwing the bolts into the threaded holes. When it is necessary to replace the fixing plates with different curvatures, it is necessary to rotate the fixing plates several times to remove them, and then rotate them several times to install them. This is not convenient. Moreover, after frequent twisting, the threaded holes and bolts may become stripped, affecting the installation of the fixing plates.

[0005] Therefore, this utility model designs a bearing processing positioning device to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a bearing processing positioning device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bearing processing positioning device, comprising: a base, wherein long grooves are provided on both sides and the middle of the top of the base, a screw is rotatably installed in the long grooves on both sides, and a positive and negative threaded rod is rotatably installed in the long groove in the middle, a screw block is slidably installed on the outer wall of the screw through a thread, and thread blocks are slidably installed on the outer walls of both ends of the positive and negative threaded rod through a thread, and an insert block is installed on one side of the screw block and one end of the thread block, and a clamping plate is provided on the insert block through a replaceable component.

[0008] Preferably, the replacement component includes two grooves, which are respectively formed on both sides of the insert block. A movable block is slidably installed in the groove. The movable block and the insert block are connected by a spring. The clamping plate has a slot for inserting into the insert block. The clamping plate has two finger grooves and two through grooves. The two finger grooves are respectively located on both sides of the slot. The finger grooves are connected to the slot through the through grooves. The movable block and the through grooves are slidably connected.

[0009] Preferably, the surface of the movable block is provided with a sponge layer, which can improve the comfort of finger pressing.

[0010] Preferably, the surface of the clamping plate is provided with a rubber anti-slip pad, which can improve the stability of the clamping plate and the bearing.

[0011] Preferably, a knob is installed on one side of the screw and one end of the positive and negative threaded rods, and the knob makes it easy to turn the screw and the positive and negative threaded rods.

[0012] Preferably, one side of the screw block, one end of the thread block, and the base are all connected by a corrugated dust cover. The corrugated dust cover is fitted on the outside of the screw and the forward and reverse threaded rods. The corrugated dust cover can reduce the amount of debris generated during grinding that adheres to the screw and the forward and reverse threaded rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By changing the component settings, this utility model allows for easy installation. Simply press the two movable blocks to allow them to enter the grooves and compress the springs. Then, align the slot of the clamping plate with the insert block and insert it. The restoring force of the spring will cause the movable blocks to pop out a certain distance and enter the through groove, thus completing the installation of the insert block and the clamping plate. For disassembly, insert your finger into the finger groove and press the movable block again to remove it from the through groove, thus removing the clamping plate. This makes disassembly and replacement much more convenient. 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 an embodiment of a bearing processing positioning device, comprising: a base 1, with elongated grooves 2 on both sides and in the middle of the top of the base 1; a screw 3 rotatably installed in the elongated grooves 2 on both sides; a positive and negative threaded rod 4 rotatably installed in the elongated groove 2 in the middle; a screw block 5 slidably installed on the outer wall of the screw 3 via a thread; threaded blocks 6 slidably installed on the outer walls of both ends of the positive and negative threaded rod 4 via threads; an insert block 7 is installed on one side of the screw block 5 and one end of the threaded block 6; a clamping plate 8 is provided on the insert block 7 via a replacement component 9; when grinding the outer side of the bearing ring, the positive and negative threaded rod 4 in the middle is rotated, so that the two clamping plates 8 in the middle clamp and fix the inner wall of the bearing ring, making it convenient for the worker to grind the outer wall; when grinding the inner wall of the bearing ring, the two clamping plates 8 in the middle move closer to each other and away from the bearing ring, and then the screw is rotated, so that the two clamping plates 8 on both sides move closer to each other, thus clamping and fixing the outer wall of the bearing ring, making it convenient for the worker to grind the inner wall.

[0022] Please see Figure 1-3In this embodiment: the replacement component 9 includes two grooves 901, which are respectively opened on both sides of the insert block 7. A movable block 902 is slidably installed in the groove 901. The movable block 902 and the insert block 7 are connected by a spring 903. The clamping plate 8 is provided with a slot 904 for inserting into the insert block 7. The clamping plate 8 is provided with two finger grooves 905 and two through grooves 906. The two finger grooves 905 are respectively located on both sides of the slot 904. The finger grooves 905 are connected to the slot 904 through the through grooves 906. The movable block 902 and the through groove 906 are slidably connected.

[0023] Please see Figure 1-3 In this embodiment: the surface of the movable block 902 is provided with a sponge layer.

[0024] Please see Figure 1-3 In this embodiment: the surface of the clamping plate 8 is provided with a rubber anti-slip pad 10.

[0025] Please see Figure 1-3 In this embodiment, a knob 11 is installed on one side of the screw 3 and one end of the positive and negative threaded screw 4.
