Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting, in particular to a flexible automatic press-fitting device. Background Art

[0002] Press-fitting equipment is widely used in industry. Press-fitting equipment in the prior art mostly adopts a rigid fixed press head design. When the pressed position structure of the parts has a small range of deviation, the existing press head has no adaptive adjustment capability. However, many hole positions do not require very high position accuracy in terms of product performance, and high-precision processing directly leads to increased difficulty in parts processing and high costs. Therefore, there is an urgent need for a flexible and adaptive press-fit assembly tool.

[0003] Therefore, when it comes to press-fitting parts that allow for a small range of deviation, how the press-fitting equipment can adapt to the precision of the parts is a problem that needs to be solved. Utility Model Content

[0004] In order to solve the technical problems mentioned in the background technology, the utility model provides a flexible automatic press-fitting device, which can adaptively float laterally without affecting the verticality of the press-fitting direction.

[0005] In the first aspect, the utility model provides a flexible automatic pressing device including a fixing cap having a through hole at the center thereof; a pressing head, the front portion of which extends out from the through hole, and the rear portion abuts against the inner wall of the through hole of the fixing cap, and an annular gap is formed between the rear side wall of the pressing head and the inner side wall of the fixing cap; and a lateral spring, which is arranged in the annular gap to hold the pressing head laterally.

[0006] Specifically, at least two lateral springs are provided, and each lateral spring is equidistantly mounted on the pressure head.

[0007] Preferably, the pressure head is provided with grooves matching with each lateral spring.

[0008] Furthermore, the flexible automatic press-fitting device also includes a thrust rod, which is detachably connected to the fixing cap.

[0009] Furthermore, the thrust rod and the fixing cap are connected by threaded connection.

[0010] Furthermore, a recess adapted to the press-fit workpiece is provided at the front end of the press head.

[0011] The beneficial effect of the utility model is that, when a certain position deviation is allowed in the processing of the part hole, the pressure head can be laterally adjusted in the annular gap between the pressure head and the lateral spring in the inner wall of the fixing cap through the elastic force of the lateral spring. This can not only ensure that the axis of the pressure head is always parallel to the pressure direction, but also allow the pressure head to float laterally adaptively, thereby meeting the manufacturing requirements of parts and components, reducing production costs and improving production efficiency.

[0012] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model. The purpose and other advantages of the utility model are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0013] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0019] like Figure 1As shown, this embodiment provides a flexible automatic pressing device including a fixing cap 1, a through hole is provided in the center thereof; a pressing head 3, the front portion of which extends out from the through hole, and the rear portion abuts against the inner wall of the through hole side of the fixing cap 1, and an annular gap 5 is formed between the rear side wall of the pressing head 3 and the inner side wall of the fixing cap 1; and a lateral spring 4, which is arranged in the annular gap 5 to hold the pressing head 3 laterally.

[0020] Specifically, at least two lateral springs 4 are provided, and each lateral spring 4 is installed on the pressure head 3 at equal distances.

[0021] Preferably, the pressure head 3 is provided with grooves matching with each lateral spring 4 .

[0022] Furthermore, the flexible automatic press-fitting device also includes a lateral spring 4, and the lateral spring 4 is detachably connected to the fixing cap 1.

[0023] Furthermore, the lateral spring 4 and the fixing cap 1 are connected by threaded connection.

[0024] Furthermore, a recess adapted to the press-fit workpiece is provided at the front end of the press head 3 .

[0025] like Figure 2 As shown, taking a steel ball press-fitting device as an example, during the use of the press-fitting device, after the thrust rod 6 is driven, the pressure in the vertical direction is decomposed into a circumferential force through a contoured pit with a steel ball diameter provided at the front end of the pressure head 3, and the circumferential force is dispersed into the elastic force of multiple lateral springs 4; since each lateral spring 4 is in the annular gap 5 formed by the pressure head 3 and the fixed cap 1, under the elastic force of each lateral spring 4, the pressure head 3 can cooperate to adjust the position laterally in the annular gap 5; on the one hand, the elastic force of the lateral spring 4 enables the pressure head 3 to be better adjusted to the coaxial position with the through hole in the center of the fixed cap 1, ensuring that the axis of the pressure head 3 is always parallel to the pressure direction; on the other hand, since the pressure head 3 is sleeved in the annular gap 5 of the fixed cap 1, it can follow the circumferential floating to adjust the position by a small amount. Preferably, in order to ensure that the pressure head 3 is not affected by the friction force generated by the pressure when floating on the side, grease can be applied to the axial gap between the pressure head 3 and the fixed cap 1 and the lateral spring 4 to reduce the friction.

[0026] To sum up, when there is a certain position deviation in the processing of part holes, the utility model can provide a pressing device that is adaptive to lateral floating without affecting the verticality of the pressing direction, adapting to the manufacturing requirements of parts, reducing production costs and improving production efficiency.
