Description

Technical Field

[0001] The utility model relates to the field of bearing outer rings, and more specifically, to a fixing component for machining bearing outer rings. Background Art

[0002] The outer ring of the bearing is an important component of the bearing. It is annular in structure and has precisely set inner diameter, outer diameter and width dimensions. It is usually made of high-carbon chromium bearing steel, carburized steel, stainless steel and other materials with good strength, hardness, wear resistance and toughness.

[0003] During the processing of the outer ring of the bearing, both its inner and outer surface areas need to be polished. The outer surface of the outer ring is polished to ensure that its dimensional accuracy and surface roughness meet the requirements, so that it can achieve good cooperation with the installation components and ensure the stability and accuracy of the installation. The inner surface is polished mainly to form a precise raceway so that the rolling elements can roll smoothly, reduce friction and wear, and improve the operation accuracy and service life of the bearing. This requires the outer ring of the bearing to be fixed inside and outside by two types of clamps, that is, the outer ring of the bearing is fixed by clamping the outer surface of the outer ring of the bearing, or the outer ring of the bearing is fixed by clamping the inner surface of the outer ring of the bearing. (By fixing the bearing by clamping the inner surface, the outer surface of the bearing can be processed, and vice versa. This can avoid obstructions during grinding) before the grinding of the outer ring of the bearing can be completed, which is more troublesome.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a fixing assembly for machining a bearing outer ring. Utility Model Content

The inner and outer surfaces of the bearing outer ring can be fixed by driving the two clamping blocks to move synchronously through the transmission mechanism.

[0007] Preferably, the transmission mechanism is operated by a pneumatic cylinder.

[0009] Preferably, baffles are installed on both the front and rear sides of the clamping block to prevent the outer ring of the bearing from moving in the axial direction after being fixed, mainly to deal with large-scale movement.

[0010] Preferably, the clamping block and the baffle are detachably connected, and the staff can choose whether to install them according to needs.

[0011] Preferably, limiting square blocks are welded on the front and rear sides of the clamping block, and a square through groove is opened inside the baffle for the limiting square block to pass through. The surface of the limiting square block is fixedly connected with a screw threadedly connected to the nut on the outer wall, which is easy to disassemble.

[0012] Preferably, anti-skid pads are bonded to the surfaces of the arc-shaped portion A and the arc-shaped portion B, and the anti-skid pads are used to prevent the outer ring of the bearing from sliding slightly, thereby improving the processing accuracy.

Such a fixing assembly can realize the clamping and fixing of the inner surface of the outer ring of the bearing and the clamping and fixing of the outer surface of the outer ring of the bearing, thereby solving the problem of the background technology that the outer ring of the bearing needs to be fixed inside and outside respectively by two clamps, which is relatively troublesome;

[0016] 3. The utility model passes the square through slot on the baffle through the limiting square block. After passing through, a nut is installed on the screw of the limiting square block. The nut moves along the screw and slowly presses against the surface of the baffle, thereby completing the fixing of the baffle. When disassembling, it only needs to rotate the nut in the opposite direction to remove the nut, and then pull the baffle off the limiting square block to realize its disassembly, which is relatively convenient for disassembly and assembly;

[0017] 4. The transmission mechanism in the utility model can ensure the synchronous operation of the two clamping blocks. In addition, compared with the traditional method of driving the clamping blocks to operate synchronously through cylinders and connecting rods, the two clamping blocks have a larger range of motion and are more suitable for use with the fixing assembly.

[0026] like Figure 1-4As shown, the utility model provides a fixing assembly for processing a bearing outer ring, comprising a transmission mechanism 1 for driving two clamping blocks 2 to move, wherein the opposite sides of the two clamping blocks 2 are arc-shaped portions A201 that match the outer surface of the bearing outer ring, and the other sides of the clamping blocks 2 are arc-shaped portions B202 that match the inner surface of the bearing outer ring. The inner and outer surfaces of the bearing outer ring can be fixed by driving the synchronous movement of the two clamping blocks 2 through the transmission mechanism 1.

[0027] During use, when it is necessary to clamp the inner surface of the bearing outer ring, the two clamping blocks 2 can be first pulled to the shortest distance through the transmission mechanism 1, and then the bearing outer ring is sleeved on the periphery of the two clamping blocks 2 and flush with the clamping blocks 2, and then the two clamping blocks 2 are driven to move to both sides by the transmission mechanism 1, and the inner surface of the bearing outer ring can be fixed by the arc portion B202 on the clamping block 2, so that its outer surface can be processed. Conversely, the two clamping blocks 2 are first pulled to the farthest distance through the transmission mechanism 1, and then the bearing outer ring is placed between the two clamping blocks 2 and flush with the clamping blocks 2, and then the two clamping blocks 2 are driven to move to the middle part by the transmission mechanism 1, and the outer surface of the bearing outer ring is clamped and fixed by the arc portion A201, so that its inner surface can be processed. In this way, a fixing component can clamp and fix the inner surface of the bearing outer ring and the outer surface of the bearing outer ring.

[0028] Furthermore, baffles 3 are installed on both the front and rear sides of the clamping block 2 to prevent the bearing outer ring from moving in the axial direction (large-scale movement) after being fixed. The distance between the baffles 3 is slightly larger than the width of the bearing outer ring. The surfaces of the arc portion A201 and the arc portion B202 are bonded with anti-slip pads 8. When clamping, the bearing outer ring will be squeezed and contacted with the anti-slip pad 8. The anti-slip pad 8 can prevent the bearing outer ring from sliding slightly, thereby improving the processing accuracy. The above two improvements can be selected and applied according to needs.

[0029] The clamping block 2 and the baffle 3 are detachably connected, and the staff can choose whether to install it as needed to improve the convenience of the fixed assembly. The following is the specific detachable structure: the front and rear sides of the clamping block 2 are welded with limiting square blocks 4, and the interior of the baffle 3 is provided with a square through groove 5 for the limiting square block 4 to pass through. The surface of the limiting square block 4 is fixedly connected with a screw 6 threadedly connected to the nut 7 on the outer wall, that is, the square through groove 5 on the baffle 3 is passed through the limiting square block 4. After passing through, the nut 7 is installed on the screw 6 of the limiting square block 4. The nut 7 moves along the screw 6 and slowly presses against the surface of the baffle 3, thereby completing the fixation of the baffle 3. When disassembling, you only need to rotate the nut 7 in the opposite direction to remove the nut 7, and then pull the baffle 3 off the limiting square block 4 to achieve its disassembly, which is relatively easy to disassemble and assemble (the method of limiting first and then fixing is more convenient for the staff to operate).

[0030] The transmission mechanism 1 is controlled and operated by the cylinder 101. The transmission mechanism 1 includes a frame plate 102. The back of the frame plate 102 is fixedly connected to a vertical plate 103, and a bearing 104 is embedded and fixed inside the vertical plate 103. A rotating rod 105 is fixedly connected to the inner ring of the bearing 104. The head of the rotating rod 105 is fixedly connected to a gear 106. The upper and lower sides of the inner surface of the frame plate 102 are fixedly connected to guide rails 107 for sliding sliders 108. The top of the slider 108 is installed with a tooth plate 109, and the tooth plate 109 and the gear 106 are meshed and connected with each other. The surface of the tooth plate 109 is fixed to the back of the clamping block 2 through a connecting plate 110. The cylinder 101 is fixed to the back of the vertical plate 103, and drives one of the clamping blocks 2 to move through the transmission plate 111.

[0031] That is, when the cylinder 101 drives one of the clamping blocks 2 to move toward the position of the gear 106 or away from the position of the gear 106 through the transmission plate 111, the clamping block 2 will drive the movement of one of the gears 106 through the connecting plate 110, and the toothed plate 109 will drive the rotation of the gear 106, the gear 106 drives the rotation of the rotating rod 105, the rotating rod 105 drives the rotation of the inner ring of the bearing 104, and the inner ring of the bearing 104 rotates along its outer ring to support the gear 109 for rotation through the bearing 104, and drive the movement of another toothed plate 109 through the gear 106, and finally drive the movement of another clamping block 2. Thereby, the two clamping blocks 2 are driven to move toward the middle or to both sides at the same time. During the movement of the tooth plate 109, the slider 108 is driven to move, and the slider 108 slides along the guide rail 107. The advantage of this design is that it can ensure the synchronous operation of the two clamping blocks 2. In addition, compared with the traditional method of driving the clamping blocks 2 to run synchronously by the cylinder 101 and the connecting rod, the two clamping blocks 2 have a larger range of movement and are more suitable for use with this fixing component (this fixing component must not only move the two clamping blocks 2 to the middle for clamping, but also move the two clamping blocks 2 to the closest distance for the outer ring of the bearing 104 to be inserted).

[0032] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
