Specifically, when a person uses it, the person first places the bearing into the interior of the placing frame 6, and the person rotates the handle 4 to drive the bidirectional screw rod 3 to rotate, and the two screw sleeves 5 are simultaneously forced to approach each other, and the screw sleeves 5 move It also drives the corresponding cross bar 13 to move, and the cross bar 13 drives the corresponding long rod 10 to move, and the long rod 10 drives the arc plate 9 to move inside the placement frame 6 until the two arc plates 9 are in contact with the outer ring of the bearing to be processed to achieve the effect of extrusion and clamping. At this point, the auxiliary fixing operation is completed to facilitate the subsequent operation of the personnel. Through the structural design, the personnel can quickly rotate the bidirectional screw 3 to control the arc plate 9 to assist in clamping the bearing. The adjustment method is simple and easy to use, and can provide a stable supporting locking force for the arc plate 9 in the clamping state, and will not slip due to excessive force, thereby increasing the safety of the production process.
[0025] This program has the following working process:
[0026] When in use, personnel first place the bearing into the placement frame 6, and then rotate the handle 4 to drive the bidirectional screw 3 to rotate. The two screw sleeves 5 are simultaneously forced to move closer to each other, and the displacement of the screw sleeves 5 also drives the corresponding cross bar 13 to move. The cross bar 13 drives the corresponding long rod 10 to move, and the long rod 10 drives the arc plate 9 to move inside the placement frame 6 until the two arc plates 9 are in contact with the outer ring of the bearing to be processed to achieve the effect of extrusion and clamping. At this point, the auxiliary fixing operation is completed, which is convenient for subsequent operations by personnel.
[0027] According to the above working process, we can know that:
[0028] Through the structural design, personnel can quickly rotate the bidirectional screw 3 to control the auxiliary clamping operation of the arc plate 9 on the bearing. The adjustment method is simple and easy to use, and can provide a stable supporting locking force for the arc plate 9 in the clamping state.

[0034] To sum up: when personnel use it, they first place the bearing into the placement frame 6, rotate the handle 4 to drive the bidirectional screw 3 to rotate, and the two screw sleeves 5 are simultaneously forced to move closer to each other, and the displacement of the screw sleeve 5 also drives the corresponding cross bar 13 to move, and the cross bar 13 drives the corresponding long rod 10 to move, and the long rod 10 drives the arc plate 9 to move inside the placement frame 6 until the two arc plates 9 are in contact with the outer ring of the bearing to be processed to achieve the effect of extrusion and clamping. At this point, the auxiliary fixing operation is completed to facilitate the subsequent operation of the personnel. The stability of the placement frame 6 is guaranteed by the setting of the support column 7, and the bidirectional screw is maintained by the setting of the vertical plate 2. The balance of 3 is maintained by the setting of the long rod 10, which maintains the screw sleeve 5 not to rotate with the bidirectional screw rod 3. The setting of the handle 4 increases the friction force when the person rotates the bidirectional screw rod 3. The setting of the spring 11 and the baffle 12 enables the long rod 10 to have the ability of buffering during the displacement process.
