Description

Technical Field

[0001] The utility model relates to the field of shaft collar processing, in particular to a clamping device suitable for shaft collars with different diameters. Background Art

[0002] The shaft collar is a separate annular part that can be fitted onto the shaft. It has the same function as the shaft shoulder and is used for axial positioning of the part. The shaft shoulder and shaft collar are the most reliable positioning methods for parts on the shaft. During the processing of the shaft collar, a clamping device is required to fix the shaft collar to prevent movement during the processing.

[0003] According to a Chinese patent with publication number CN215588645U, a bearing processing and grinding device is disclosed. The utility model adopts a rotating block, a clamping block, a positioning column and a bidirectional screw. The bearing to be processed is set on the positioning column, and then the rotating block is rotated to drive the bidirectional screw to rotate. Since the bidirectional screw and the clamping block are threadedly connected, the two clamping blocks are pushed against the bearing ring, thereby fixing the bearing ring. This fixing method is relatively stable, will not deviate, and has high processing accuracy.

[0004] With regard to the above-disclosed patent content, a positioning column is provided so that the bearing can be positioned on the positioning column, but the diameter of the positioning column is fixed, so that it can only be assembled with bearings with the same inner diameter. When the inner diameter of the bearing increases, there is a gap between the positioning column and the bearing, which makes it impossible for the bearing to be firmly mounted on the positioning column. Therefore, it is necessary to replace positioning columns of different diameters in order to assemble bearings with different inner diameters. This operation process is relatively cumbersome, thereby reducing the scope of application of the clamping device. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a clamping device suitable for low-shaft rings of different diameters, so as to solve the technical problem that it is inconvenient to sleeve bearings of different inner diameters on the positioning column, thereby reducing the application range of the clamping device.

[0010] Furthermore, the length of the fastening bolt is greater than the length of the threaded rod, and the fastening bolt is threadedly connected to the threaded rod and the positioning tube.

[0011] By adopting the above technical solution, when the fastening bolt is screwed into the interior of the positioning tube, the threaded rod can be limited to prevent the threaded rod from rotating at will.

[0012] Furthermore, a plurality of protrusions are installed on one end of the slide rod, and the slide seat is slidably connected to the slide rod.

[0013] By adopting the above technical solution, the slide seat can slide on the slide rod, thereby improving the stability of the slide seat when moving, and facilitating the slide seat to drive the top block to move.

[0014] Furthermore, the push plate is rotatably connected to the slide seat via a rotating shaft.

[0015] By adopting the above technical solution, the setting of the rotating shaft facilitates the rotation of the push plate, and the push plate will push the slide seat to move after rotating.

[0016] Furthermore, one side of the top block is arc-shaped, and the size of the top block is smaller than the size of the through opening.

[0017] By adopting the above technical solution, the side wall of the top block is in an arc shape, which is convenient for contacting with the inner wall of the shaft ring, thereby preliminarily positioning the shaft ring.

[0020] Furthermore, two movable seats are sleeved on the outer wall of the bidirectional screw rod, and a clamping plate is installed on the top of the movable seat.

[0021] By adopting the above technical solution, when the bidirectional screw rod rotates, it drives the two movable seats to move simultaneously, and the movable seats drive the two clamping plates to move closer or farther away.

[0022] Furthermore, the positioning tube is located between two clamping plates, an arc groove is provided on one side of the clamping plate, and the thickness of the clamping plate is smaller than the thickness of the positioning tube.

[0023] By adopting the above technical solution, the arrangement of the arc groove facilitates the clamping of the shaft collar, and the arrangement of the positioning tube allows the shaft collar to be sleeved on its outer wall, thereby positioning the shaft collar.

[0024] Furthermore, the movable seat is threadedly connected to the bidirectional screw rod, and one end of the bidirectional screw rod is connected to the inner wall of the groove through a bearing.

The positioning cylinder 3 is located between the two clamping plates 2. An arc groove 8 is provided on one side of the clamping plate 2. The setting of the arc groove 8 is convenient for clamping the outer wall of the shaft ring. The thickness of the clamping plate 2 is less than the thickness of the positioning cylinder 3. The movable seat 7 is threadedly connected to the two-way screw rod 5. One end of the two-way screw rod 5 is connected to the inner wall of the groove 4 through a bearing. The setting of the bearing can improve the stability of the two-way screw rod 5 when it rotates.

[0039] Specifically, the adjustment component 9 includes a threaded rod 901 arranged inside the positioning cylinder 3 through a bearing, a plurality of through openings 907 opened on the outer wall of the positioning cylinder 3 and a plurality of sliding rods 903 installed on the inner wall of the positioning cylinder 3. The outer walls of the plurality of sliding rods 903 are all sleeved with a sliding seat 904. A plurality of protrusions 905 are installed at one end of the sliding rod 903. The setting of the protrusion 905 can prevent the sliding seat 904 from sliding off the sliding rod 903. The sliding seat 904 is slidably connected to the sliding rod 903. The sliding seat 904 can slide on the sliding rod 903, thereby improving the stability of the sliding seat 904 when moving, making it easier for the sliding seat 904 to drive the top block 906 to move.

When clamping collars of different diameters, it is only necessary to adjust the distance between the two clamping plates 2.

[0045] When it is necessary to clamp the shaft rings with different inner diameters, the user can first rotate the fastening bolt 902 so that the fastening bolt 902 no longer contacts the positioning tube 3. At this time, the fastening bolt 902 no longer limits the threaded rod 901. Then the user can rotate the threaded rod 901 through the turntable 910. After the threaded rod 901 is rotated, the adjustment seat 908 can be moved. Then the slide seat 904 can be pushed to move through the push plate 909. The slide seat 904 drives the top block 906 to move. The top block 906 can be moved out from the inside of the through opening 907, thereby facilitating the adjustment of the position of the top block 906 so as to be able to assemble shaft rings with different inner diameters.
