Description

Technical Field

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

[0002] When installing or processing bearings, positioning fixtures or tools are needed to hold and fix them in place, ensuring that they are secure and do not shift during installation or operation, thus guaranteeing the accuracy of installation and operation. However, traditional positioning fixtures or tools have limited functionality and cannot meet the needs of clamping and fixing bearings of various models, sizes, and those with screws.

[0003] Existing bearing clamping and positioning fixtures have limited functionality and cannot meet the needs of fixing and clamping various types of bearings. For example, a bearing production polishing clamping and positioning fixture disclosed in CN220481326U includes a worktable, an operating table mounted on the top of the worktable, and a bearing high-efficiency polishing mechanism mounted on the top of the operating table; one end of a threaded screw is fixedly connected to the output end of a drive motor, and the other end of the threaded screw is rotatably connected to one end of the inner wall of a guide groove; a sliding block is threadedly sleeved on the threaded screw, and a clamping plate slides... The movable clamp is attached to the top of the guide groove, and the bottom of the clamping plate is fixedly connected to the top of the sliding block. The limiting clamp is slidably attached to the clamping surface of the clamping plate. Therefore, by driving the drive motor, the threaded screw can be rotated, which in turn can drive the sliding block to move in the guide groove, and thus drive the clamping plate to clamp the bearing. Under the action of the limiting clamp, the clamping effect of the bearing can be further improved. However, the clamp in this solution can only be used to clamp the bearing inside the hub or the outer sleeve of the shaft. If it is a bearing with a screw, it is not easy to clamp it firmly.

[0004] Therefore, it is necessary to invent a bearing positioning fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a bearing positioning fixture to solve the problems of the current bearing positioning fixture having a single function that cannot adapt to bearings of various sizes and cannot clamp and fix bearings with screws.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bearing positioning fixture includes a main body, a first positioning ring, a second positioning ring, an air extraction hole, and a third positioning ring. The main body is provided with the first and second positioning rings. The diameter of the first positioning ring is larger than that of the second positioning ring. Multiple air extraction holes are evenly distributed on the inner bottom surfaces of the first and second positioning rings. A one-way valve is installed through the air extraction hole at the bottom of the main body. The one-way valve is connected to one end of a gas hose, and the other end of the gas hose is installed on an air extraction pump. The main body is also provided with multiple limiting plates. The third positioning ring is slidably connected to the limiting plates. The positioning hole in the third positioning ring allows the screw on the bearing to be inserted.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] This utility model utilizes positioning rings of various diameters, including two positioning rings, to accommodate bearings of different diameters. These rings, along with an air pump and air extraction port, ensure secure clamping of the bearings. A third positioning ring is used to clamp bearings with screws. The entire positioning fixture is highly practical and has a wider range of applications. The sliding fit between the third positioning ring and the limiting plate allows for fine-tuning of the ring's position, facilitating the fixing of bearings with screws of different diameters. The third positioning ring offers multiple clamping methods for screw-bearings: one downward insertion clamping, and another side bolt insertion into a fixing bolt hole. This dual-fixing effect enhances the clamping's stability. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figures 1-3 The bearing positioning fixture shown includes a positioning fixture body 1, a positioning ring 1 2, a positioning ring 2 3, an air extraction hole 4, and a positioning ring 3 9. The positioning fixture body 1 is provided with positioning ring 1 2 and positioning ring 2 3. The diameter of positioning ring 1 2 is larger than that of positioning ring 2 3. Multiple air extraction holes 4 are evenly opened on the bottom surface of positioning ring 1 2 and positioning ring 2 3. The air extraction hole 4 passes through the bottom of the positioning fixture body 1 and is equipped with a one-way valve 5. The one-way valve 5 is connected to one end of a gas hose 6. The other end of the gas hose 6 is installed on an air extraction pump 7. Multiple limiting plates 8 are also provided on the positioning fixture body 1. The positioning ring 3 9 is slidably connected to the limiting plate 8. The positioning hole 901 opened in the positioning ring 3 9 can insert the screw on the bearing.

[0019] The entire positioning fixture body 1 can accommodate the fixing and clamping of bearings of different diameters, as well as bearings with screws, making it widely applicable.

[0020] The limiting plate 8 has a sliding groove 801, which is arrow-shaped. Circular insertion holes 802 are evenly distributed on two opposite sides of the sliding groove 801. A positioning hole 901 is provided at the center of the positioning ring 9. Multiple fixing bolt holes 902 of the same diameter are provided on the side of the positioning ring 9, and each fixing bolt hole 902 is connected to the positioning hole 901. Multiple clamping members 903 are slidably connected inside the positioning ring 9. The initial state of the multiple clamping members 903 is that multiple strong magnetic adsorption layers 904 are tightly attached. The multiple clamping members 903 are distributed in a ring array about the center of the positioning ring 9.

[0021] The cooperation between the positioning ring 39 and the slide groove 801 allows for fine adjustment of the position of the positioning ring 39 within the slide groove 801, better adapting to the clamping and fixing of bearings with screws of different diameters.

[0022] The bottom of the positioning ring 9 is fixedly connected to the base 905. The push button 906 is installed on the side of the base 905 and is located in the middle of the two insertion rods 907. The diameter of the insertion rods 907 matches the diameter of the insertion hole 802. When the push button 906 is squeezed, it will cause the insertion rods 907 on both sides to retract, releasing the fixation between the base 905 and the slide groove 801.

[0023] The diameter of the fixing bolt hole 902 is adapted to the diameter of the general-purpose bolt rod. The sliding trajectory of the multiple clamping parts 903 is to spread outward along the positioning ring 9 as the center. The bottom of the multiple clamping parts 903 does not contact the base 905.

[0024] Working principle of this utility model:

[0025] Refer to the instruction manual appendix Figures 1-3 When using this utility model, firstly, when the bearing body needs to be processed or installed, the positioning fixture body 1 needs to be used for fixing and clamping. The positioning ring 2 and positioning ring 3 of the positioning fixture body 1 can adapt to the placement of bearing parts of different diameters.

[0026] After the bearing components are placed, the switch on the air pump 7 is turned on, and the one-way valve 5 is opened, which strongly adsorbs and fixes the bearing components placed within the range of positioning ring 1 2 or positioning ring 2 3.

[0027] Refer to the instruction manual appendix Figures 3-5 When using this utility model, the design of multiple positioning rings 9 can meet the clamping and fixing of bearings with screws. When the screw is inserted into the positioning hole 901, the multiple clamping parts 903 that were originally attracted together are spread apart, and under the action of the strong magnetic adsorption layer 904, they still maintain a force that keeps them close to each other, thus clamping the screw.

[0028] It can also further insert the bolt into the fixing bolt hole 902 to tighten the screw on the bearing (when it is necessary to make a fine adjustment to the position of the positioning ring 9, the push button 906 needs to be pressed, and the two side rods 907 are retracted into the base 905, and the originally fixed rods 907 and the insertion hole 802 are loosened, so that the position of the positioning ring 9 in the slide groove 801 can be flexibly adjusted. After releasing the push button 906, the positioning ring 9 can be restored to the state of being fixed to the limiting plate 8).
