Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing ring processing, in particular to a clamping tooling for machining bearing rings by machine. Background Technique
[0002] As a key component of a bearing, the processing precision and quality of a bearing ring directly affect the overall performance and service life of the bearing. Therefore, in the process of machining a bearing ring, high-precision and high-stability machine tools need to be used to ensure that the machined bearing ring meets the requirements. When drilling a bearing ring, the drilling machine tool needs to have a high-precision positioning system to ensure the accuracy of the drilling position. The machining process of the bearing ring also requires the machine tool to maintain high stability to reduce the influence of vibration and tremor on the machining precision. Therefore, it is particularly important to stably fix and clamp the bearing ring during the machining process and ensure that there is no offset and vibration when machining each hole during movement.
[0003] When the existing bearing ring processing device processes a bearing ring with a large size, the clamping stability is insufficient, and the device is also limited by the size and cannot adapt to the processing of more bearing rings with larger size ranges, so the use is restricted.

Detailed implementation manners
[0024] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0025] As Figure 1 - Figure 2 shown, an automatic processing device for a bearing ring to which the clamping tool for machining a bearing ring of the present utility model is applied. This processing device mainly includes the clamping tool of the present utility model and a driving rotation mechanism for driving the clamping tool and the bearing ring workpiece to rotate. The rotation function provided by the driving rotation mechanism can meet the needs of machining different positions of the bearing ring, and at the same time provides a supporting role for the clamping tool of the present utility model. Specifically, the present utility model can be implemented as follows:
[0026] Please refer to Figure 1 - Figure 3, the positioning and mounting seat 1 of the present utility model is mainly composed of multiple positioning steel pipes. Preferably, two positioning steel pipes are perpendicularly and crosswise combined to form a cross-shaped steel pipe positioning and mounting seat 1, enabling the bearing ring workpiece 32 to be positioned, fixed, and clamped at four positions on the cross-shaped steel pipe. More positioning steel pipes can also be provided, maintaining a uniform and equal angle with each other to further improve the positioning and clamping accuracy and stability. The multiple positioning and mounting holes 2 provided on the positioning steel pipes can ensure that bearing ring workpieces 32 within different size ranges can be installed, fixed, and clamped on the positioning and mounting seat 1, expanding the applicable range of device processing. The positioning, fixing, and clamping of the bearing ring workpiece 32 are mainly completed by multiple groups of positioning and fixing mechanisms installed on the positioning and mounting holes 2. When the number of positioning steel pipes is two, the bearing ring workpiece 32 needs to be positioned, fixed, and clamped at four positions on the ring, so a total of four groups of positioning and fixing mechanisms are provided. And so on, for each additional positioning steel pipe, two groups of positioning and fixing mechanisms are provided on that positioning steel pipe to ensure uniform force during positioning and clamping. The positioning and fixing mechanism mainly consists of an internal fixing and clamping member 3 arranged close to the center of the positioning and mounting seat 1 and an external positioning and clamping member 4 arranged away from the center of the positioning and mounting seat 1. They clamp and fix the bearing ring workpiece 32 from two positions and directions, namely the inside and outside of the bearing ring workpiece 32 (including horizontal and vertical directions, etc.), improving the clamping stability. Moreover, the internal fixing and clamping member 3 and the external positioning and clamping member 4 are installed and used in cooperation with multiple positioning and mounting holes 2, which can make the adjustable distance precision of the fixed clamping unit higher, the clamping position more accurate, and the clamping effect better.
[0027] Please refer to Figure 7 , to solve the problem that when the size of the bearing ring workpiece 32 is larger than the size of the positioning and mounting seat 1, it cannot be installed and processed, the present utility model is provided with an extension member 24 that can be connected to the end of the positioning steel pipe of the positioning and mounting seat 1. The extension member 24 can also adopt a steel pipe structure for convenient connection. The extension member 24 is divided into a butt joint section 241 for butt-jointing with the positioning steel pipe and an extension section 242 for extending the range of the positioning and mounting seat 1. The diameter size of the extension member 24 in the butt joint section 241 is slightly larger than the diameter size of the positioning steel pipe, so that it can be sleeved on the end of the positioning steel pipe, while the extension section 242 can be set to have the same size as the positioning steel pipe to ensure that all mounting positions of the positioning and mounting seat 1 are on the same plane. Multiple extension holes 243 with the same function as the positioning and mounting holes 2 are also provided on the extension section 242 to meet the installation of the clamping mechanism.
[0028] Please refer to Figure 1 , Figure 2 and Figure 6, the multiple positioning steel pipes provided by the present utility model can be configured with different combinations of upper positioning steel pipes 9 and lower positioning steel pipes 10 for connection. The steel pipe upper combination groove 11 at the center of the bottom of the upper positioning steel pipe 9 and the steel pipe lower combination groove 12 at the center of the top of the lower positioning steel pipe 10 can be combined up and down in a crossed relative position. When the depths of the upper and lower grooves are both half of the outer diameter of the positioning steel pipe, the height of the formed positioning and mounting seat 1 after combination is equal to the outer diameter of one positioning steel pipe. As a preferred implementation, after the steel pipe upper combination groove 11 and the steel pipe lower combination groove 12 are combined and connected to each other, the combination can be fixedly connected by welding to improve its stability. To further enhance the stability and strength of the positioning and mounting seat 1, a steel pipe strengthening and fixing member 13 can also be added at the center of the positioning and mounting seat 1, that is, at the crossed connection of multiple positioning steel pipes (either at the top or bottom), and all the positioning steel pipes are fixedly connected by the steel pipe strengthening and fixing member 13 at this position to further improve the stability of the positioning and mounting seat 1.
[0029] Please refer to Figure 2 , since the surface of the positioning steel pipe is a cylindrical surface, the stability is insufficient when installing other mechanisms on it. To facilitate the installation of the positioning and fixing mechanism on the positioning steel pipe and improve its stability, the present utility model has opened a planar mounting groove 14 along the positioning mounting holes 2 on the positioning steel pipe, and the positioning mounting holes 2 are arranged uniformly along the planar mounting groove 14, so that the mounting surface of the positioning and fixing mechanism changes from a curved surface to a planar surface, improving its positioning, fixing and clamping stability. The spacing of the positioning mounting holes 2 can be selected and set according to processing requirements. At the same time, the positioning mounting holes 2 at different positions can be grouped, and the hole distances between the positioning mounting holes 2 within each group are uniform and the same, while the hole distances between different groups are different, so as to flexibly adapt to more processing conditions.
[0030] Please refer to Figure 3 - Figure 5, which is a schematic diagram of the specific structures of the internal fixed clamping member 3 and the external positioning clamping member 4 of the present utility model. The internal fixed clamping member 3 includes a telescopic guiding member 15 installed on the positioning steel pipe in the vertical direction. A fixed pressing block 16 is connected to the top end of the telescopic guiding member 15. The fixed pressing block 16 can be lifted and lowered in the vertical direction through the telescopic adjustment of the telescopic guiding member 15 to adapt to the height of the bearing ring workpiece. The bottom end of the telescopic guiding member 15 can be installed in the positioning installation hole 2 for fixation. A pressing block groove 17 is formed on the fixed pressing block 16. A pressing block pressing rod 18 whose bottom end is threadedly connected to the positioning installation hole 2 is installed through the pressing block groove 17. The pressing block pressing rod 18 is installed in the vertical direction, and its own height can be adjusted through the threaded connection with the positioning installation hole 2. A pressing rod nut 19 connected to the top end of the pressing block pressing rod 18 applies a downward pressure to the positioning pressing block, pressing the positioning pressing block onto the upper surface of the bearing ring workpiece 32, so that it is fixed under force in the vertical direction and does not displace; while the external positioning clamping member 4 includes a limiting block 20 installed on the positioning steel pipe. The end face of the limiting block 20 contacts the outer surface of the bearing ring workpiece 32. A limiting adjustment groove 21 is formed on the limiting block 20, and a limiting adjustment rod 22 is installed through the limiting adjustment groove 21. Through the threaded connection of the bottom end of the limiting adjustment rod 22 with the positioning installation hole 2 and the adjustment of the limiting adjustment nut 23 at the top end of the limiting adjustment rod 22, the external positioning clamping member 4 can be fixedly installed on the positioning steel pipe, and a pressure from the outside to the inside of the bearing ring workpiece 32 is applied through the contact between the limiting block 20 and the bearing ring workpiece 32. Cooperating with the external positioning clamping members 4 in multiple directions, the horizontal position of the bearing ring workpiece 32 on the positioning installation seat 1 is limited and fixed, so that the bearing ring workpiece 32 is firmly locked on the horizontal plane and does not undergo horizontal displacement, improving its stability during the processing process.
[0031] The above-described embodiments only represent the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
