Description
Technical Field
[0001] This utility model relates to the technical field of bearing precision machining, specifically a quick clamping device for bearing precision machining. Background Technology
[0002] In the utility model patent application CN114683193B, published on August 2, 2022, entitled "A Fixture for Precision Machining of Bearings," this invention relates to the field of bearing precision machining technology, specifically a fixture for precision machining of bearings. The fixture includes a disc body with a clamping module and a feeding module. Multiple grooves are formed on the top of the disc body. In this invention, an electric push rod is activated, extending its movable end. The turntable then rotates two V-shaped plates, which in turn drive two pressing plates via insert plates. During this process, the movable rod and the remaining V-shaped plates undergo angle and position changes due to mechanical transmission. These changes do not affect the feeding operation. Once the inner angles of the two V-shaped plates are aligned with the arc-shaped plate, the electric push rod is deactivated. After the bearing enters between the V-shaped and arc-shaped plates, the electric push rod is activated again. The bearing, limited by the arc-shaped plate, is firmly fixed under the pressure of the two pressing plates. Multiple bearings can be fixed simultaneously under mechanical operation, improving fixing efficiency.
[0003] In the prior art, including the aforementioned patents, even tiny impurity particles, such as dust and metal shavings, may become embedded in the bearing surface during the bearing finishing process. When subsequent turning, grinding, and other machining operations are performed, these impurities will scratch the bearing surface like tiny cutting tools. Therefore, it is necessary to design a quick clamping device for bearing finishing that can clean the clamping position. Utility Model Content

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 The present invention provides a technical solution as follows:
[0022] Example 1:
[0023] A quick clamping device for precision machining of bearings includes a base 1, a side plate 2 fixedly connected to the top of the base 1, a connecting shaft 3 installed on the outer wall of the base 1, a closing plate 4 connected to the outer wall of the base 1 via the connecting shaft 3, a guide rail 5 fixedly connected to the top of the base 1, an adjusting cylinder 6 installed on the outer wall of the side plate 2, a compressed air port 7 installed on the outer wall of the adjusting cylinder 6, an air pipe 8 fixedly connected to the output end of the adjusting cylinder 6, a clamping assembly 9 fixedly connected to the outside of the air pipe 8, and an adjusting assembly 10 installed through the output end of the adjusting cylinder 6.
[0024] The above structure is connected to an external air blowing device, and the compressed air port 7 is connected to the air pipe 8. By using air blowing, the clamping base 1 and guide rail 5 can be cleaned during the clamping process, reducing the blockage of the guide rail 5 by machining debris during the bearing finishing process.
[0025] Furthermore, two sets of closing plates 4 are provided on both sides of the base 1 via connecting shaft 3, and clamping assembly 9 and adjusting assembly 10 are slidably installed along guide rail 5.
[0026] The above structure can adapt to these diverse sizes by changing the clamping range through an adjustable quick clamping device, that is, the front, back, left and right positions of the quick clamping device can be adjusted.
[0027] Furthermore, the clamping assembly 9 includes a clamping seat 901, a central shaft washer 902, and a cleaning tube 903 inside. The clamping seat 901 is fixedly connected to the outside of the air tube 8. The central shaft washer 902 is engaged inside the clamping seat 901. The cleaning tube 903 is installed at the bottom of the clamping seat 901.
[0028] The structure described above can be adjusted according to the thickness of the bearing via the clamping assembly 9, thereby adapting to the processing of bearings with different heights and thicknesses.
[0029] Furthermore, the clamping assembly 9 is provided in two sets, and the other set of clamping seats 901 is fixedly connected to the right side plate 2.
[0030] The above structure can effectively clamp different types of bearings by changing the clamping angle or the point of force, thereby reducing the frequency of equipment replacement.
[0031] Furthermore, the internal components of the adjusting assembly 10 include a slider 1001, a support shaft 1002, a linkage rod 1003, a limit block 1004, and a spring 1005. The slider 1001 is slidably mounted on the output end of the adjusting cylinder 6. The support shaft 1002 is mounted on the outer wall of the slider 1001. The linkage rod 1003 is mounted on the outer wall of the slider 1001 through the support shaft 1002. One end of the linkage rod 1003 is slidably connected to the limit block 1004. The spring 1005 is fixedly connected to the inner side of the limit block 1004.
[0032] The above structure clamps and limits the bearing at the middle position by sliding the slider 1001.
[0033] Furthermore, the slider 1001 is located between the two sets of clamping components 9, and the center of the arc surface of the limiting block 1004 and the center of the central shaft washer 902 are on the same horizontal line.
[0034] The above structure uses the central shaft washer 902 to position the shaft center, which facilitates the limiting and fixing of the front and rear ends.
[0035] Furthermore, the limiting blocks 1004 are connected by springs 1005, and the other end of the air pipe 8 is connected to the slider 1001. An air hole is provided on the inner side of the bottom of the slider 1001, and the air hole is located on both sides of the guide rail 5.
[0036] The above structure uses the pulling force of spring 1005 to pull the limiting block 1004, thereby limiting and fixing it.
[0037] Working principle: When in use, first, the quick clamping device is installed in the machining position of the precision machining device. Then, the bearing that needs to be precision machined is clamped in the middle of the quick clamping device. The adjusting component 10 is used to limit and fix the arc surface of the bearing. Under the tension of the spring 1005, the limiting block 1004 presses against the middle, so that the arc surface of the bearing is limited.
[0038] Secondly, the adjusting cylinder 6 drives the clamping assembly 9 to move, thereby causing the clamping seats 901 to come into contact with each other, and causing the adjusting assembly 10 to squeeze each other, thereby limiting the bearing. The adjusting assembly 10 can be adjusted according to the bearing diameter. At the same time, the adjustable clamping equipment can be appropriately adjusted according to the specific shape and structural characteristics of the bearing, changing the clamping angle or force point, thereby achieving effective clamping of different types of bearings, reducing the frequency of equipment replacement, and improving production efficiency. The outer wall of the adjusting cylinder 6 is connected to an external air pump.
[0039] Finally, the system is connected via compressed air ports 7. One of the compressed air ports 7 is connected to the adjusting cylinder 6, and the other is connected to the clamping seat 901 and the slider 1001 via an air pipe 8. Air is introduced into the base 1 and the guide rail 5. An external air blowing device is connected, and the compressed air port 7 is connected to the air pipe 8. By using air blowing, the clamping base 1 and the guide rail 5 can be cleaned during the clamping process. This reduces the blockage of the guide rail 5 by machining debris during the bearing finishing process. It also facilitates sliding and cleaning along the guide rail 5 using clamping power. A clean bearing surface ensures better fit between the clamping device and the bearing. Air cleaning provides good conditions for precise clamping, ensuring the concentricity and perpendicularity of the bearing during the clamping process and reducing machining errors.
