Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, and particularly relates to a reaction force device that synchronously operates with press-fitting. Background Art
[0002] The processing production line of new energy vehicles often involves the press-fitting of important components such as shafts, bearings, and sealing rings. When the press-fitting mechanism performs press-fitting, it always clamps the workpiece through something like a jaw, and then presses the workpiece through the extension and retraction of a cylinder. However, the jaws used in traditional clamping may not be firmly fixed, which may cause the workpiece to deviate from the original position during press-fitting, affecting the normal progress of press-fitting; moreover, both the loading and unloading during press-fitting are carried out under the press head, resulting in limited operating space. Content of the Utility Model
[0003] In view of the deficiencies of the above-mentioned prior art, the utility model provides a reaction force device that synchronously operates with press-fitting to solve the above technical problems.
[0004] A reaction force device that synchronously operates with press-fitting includes a support base. A workbench is rotatably sleeved on the central column of the support base. Symmetrical press-fitting seats are slidably sleeved on the workbench. The press-fitting seats are connected with a limit ring through a return spring. A lifting cylinder is arranged at the right end of the support base. The top end of the lifting cylinder is fixedly connected with a reaction force support block. A press-fitting cylinder is installed above the reaction force support block on the support base. The bottom end of the press-fitting cylinder is fixedly connected with a profiling press head. The profiling press head pushes the limit ring higher than the press-fitting seat to move downward, so that the top end of the limit ring is lower than the top end of the press-fitting seat.
[0005] An outer peripheral gear is arranged at the bottom end of the workbench. The outer peripheral gear meshes with a straight rack. The straight rack is fixedly connected with an electric telescopic arm. The electric telescopic arm is installed on the extension column of the support base. When the electric telescopic arm contracts completely to fully extend, the workbench rotates 180°.
[0006] Furthermore, edge columns are arranged at both ends of the support base. Ball bearings are installed at the top ends of the edge columns. The workbench rotates and abuts against the ball bearings.
[0007] Furthermore, auxiliary electric telescopic arms are installed on both the central column and the right edge column. The auxiliary electric telescopic arms are fixedly connected with support plates. When the auxiliary electric telescopic arms extend, the support plates abut against the lifting cylinder.
[0008] Furthermore, a lifting rod is slidably connected to the left edge column.
[0009] Due to the adoption of the above technical solutions, compared with the prior art, the beneficial effects of the utility model include:
[0010] The position of the bearing to be press-fitted is limited by a limit ring higher than the press-fitting seat to prevent the position of the bearing to be press-fitted from shifting and affecting the normal progress of press-fitting. During press-fitting, the limit ring squeezes the return spring and does not interfere with the progress of press-fitting;
[0011] By the telescoping of the electric telescopic arm, the workbench is driven to rotate. The operator only needs to load and unload materials on the left, providing sufficient space for loading and unloading operations, and improving the orderliness of loading, press-fitting, and unloading.

[0019] The operator loads the bearing to be press-fitted on the left side. Without external force, under the action of the return spring 4, the top of the limit ring 5 is higher than the top of the press-fitting seat 3, which is convenient for the operator to put it into the press-fitting seat 3 in the limit ring 5. The electric telescopic arm 12 is fully extended to fully retracted, and the press-fitting seat 3 loaded on the left side rotates to the bottom of the profiling press head 9, the lifting cylinder 6 extends upward, and the press-fitting cylinder 8 extends downward, thereby press-fitting the bearing; while press-fitting, the operator continues to load the bearing to be press-fitted on the left side; after the press-fitting is completed, the electric telescopic arm 12 is fully retracted to fully extended, the press-fitted bearing rotates to the left side for unloading, and the bearing to be press-fitted that is loaded again rotates to the bottom of the profiling press head 9 for press-fitting, and the operation is cyclic.
