Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: an adjustable clamping device for bearing processing, comprising a plurality of support rods 1, the plurality of support rods 1 are arranged in a ring shape, a plurality of first through holes 11 are equidistantly provided on the top of the support rods 1, a plurality of clamping rings 2 are provided on the outer ring of the support rods 1, two slide grooves 21 are provided on the right side of the outer ring of the clamping ring 2, a fixing groove 22 is provided on the left side of the inner wall of the slide groove 21, a slide rod 8 is connected through the inner cavity of the slide groove 21, a clamping piece 4 is connected between the top and the bottom of the slide rod 8, a first threaded hole 41 is provided on the right side of the clamping piece 4, and a fixing groove 22 is provided between the two front and rear adjacent clamping rings 2 at the top.

[0024] When assembling the device, multiple clamping rings 2 can be put on the support rod 1, and then the clamping member 4 can be pushed to the right in the sliding groove 21, and a certain distance can be left between the right side of the inner wall of the clamping member 4 and the right side of the clamping ring 2. At this time, the sliding rod 8 will stretch the spring 7 to the right, and the spring 7 will produce elastic deformation. Then the elastic band 3 can be passed through the inner ring of the clamping member 4 and the first through hole 11 in turn, and the clamping member 4 can be loosened. At this time, the spring 7 returns to its original state and drives the clamping member 4 to move to the left. The clamping member 4 returns to its original position and clamps the elastic band 3. Then the fixing screw 10 can be passed through the first threaded hole 41 and tightened, and the elastic band 3 can be firmly fixed on the clamping ring 2. At the same time, the two ends of the elastic band 3 are respectively inserted into the two through grooves 91, and the fixing screw 10 is passed through the second threaded hole 92 and tightened. In this way, the elastic band 3 can be fixedly connected to the fixing block 9, and the installation of the entire splint can be completed.

[0025] Furthermore, when in use, the bearing workpiece can be passed through the clamping plate, and through the tightening effect of the elastic band 3, the clamping ring 2 can wrap and firmly clamp the bearing workpiece, thereby facilitating the processing of the bearing workpiece.

[0026] Furthermore, the device can adjust the clamping area of ​​the device by increasing or decreasing the number of support rods 1 and clamping rings 2. In this way, the clamping area of ​​the device can be adjusted according to the outer diameter of the bearing workpiece, so that bearing workpieces of different sizes can be clamped, providing convenience for bearing processing.

[0027] Specifically, the support rod 1 is hollow and has openings on both sides. Extension rods 5 are provided on both sides of the inner cavity of the support rod 1. A plurality of second through holes 51 are provided at equal distances on the top of the extension rod 5.

[0028] When the device is in use, the block 6 can be pressed into the slot 52, at which time the spring 7 is squeezed and deformed, and then the extension rod 5 can be pulled out of the support rod 1. When the block 6 slides to the next first through hole 11, the spring 7 returns to its original state and pushes the block 6 into the first through hole 11, so that the extension rod 5 can be re-fixed in the support rod 1, thereby increasing the length of the support rod 1.

[0029] Furthermore, after adjusting the length of the support rod 1, a clamping ring 2 can be added to the support rod 1, so that the overall length of the device can be increased. In this way, the length of the device can be adjusted according to the length of the bearing workpiece, so as to clamp bearing workpieces of different sizes, providing convenience for bearing processing.
