Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a piston press-fitting fixture for connecting seat components, especially suitable for piston press-fitting of connecting seat components in travel reducers. Background Technology

[0002] Currently, in travel reducers, pistons are mainly used in the connecting seat components with brakes. Because the braking effect needs to be controlled in the braking structure, a spring needs to be installed inside the piston to cancel the brake. At the same time, in order to facilitate the installation of the snap ring while pressing the piston during the piston installation process, a piston press-fitting fixture is required.

[0003] When installing the piston, the piston and spring need to be pressed down together, so that the upper end of the piston exceeds the lower end of the retaining ring groove to ensure that the retaining ring can be installed in place. This process requires maintaining a lot of pressure, which is very difficult to maintain manually, and the retaining ring will be difficult to install.

[0004] Therefore, how to provide a piston press-fitting fixture for connecting seat components that can facilitate the installation of snap rings by operators has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a piston press-fitting fixture for connecting seat components, which solves the technical problem of difficulty in installing snap rings when press-fitting pistons in the connecting seat components of travel reducers in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A piston press-fitting fixture for a connecting seat component includes: a press-fitting sleeve and a press-fitting plate; a press-fitting bolt passing through the press-fitting plate and contacting the press-fitting sleeve for press-fitting; and a positioning bolt passing through the press-fitting plate and screwed into a threaded hole in the connecting seat for positioning.

[0007] In practical applications, there are two positioning bolts, and the two positioning bolts are located on both sides of the press-fit bolt.

[0008] Compared with the prior art, the piston press-fitting fixture for connecting seat components described in this utility model has the following advantages: In the piston press-fitting fixture for connecting seat components provided by this utility model, the press-fitting bolt penetrates the press-fitting plate and contacts the press-fitting sleeve for press-fitting, while the positioning bolt penetrates the press-fitting plate and is screwed into the threaded hole of the connecting seat for positioning. Therefore, during use, only the middle press-fitting bolt needs to be tightened to press the piston downwards, and the pressure is maintained by the press-fitting bolt. Finally, the snap ring can be installed normally from the side using snap ring pliers. Analysis shows that the piston press-fitting fixture for connecting seat components provided by this utility model maintains pressure during the press-fitting process and facilitates snap ring installation through the cooperation of the fixture and bolts. At the same time, this fixture has a simple structure, is easy to process, has high versatility, low cost, and is easy to operate, effectively reducing the workload of workers and increasing the efficiency of the fixture. Furthermore, relying on the bolts to maintain pressure and positioning frees up manpower for maintenance, ensuring the safety of operators. Attached Figure Description

[0011] For ease of understanding, the piston press-fitting fixture for connecting seat components provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This utility model embodiment provides a piston press-fitting fixture for a connecting seat component, such as... Figure 1 As shown, it includes: a press-fit sleeve 1 and a press-fit plate 2; a press-fit bolt 3 passing through the press-fit plate 2 and contacting the press-fit sleeve 1 for press-fitting; and a positioning bolt 4 passing through the press-fit plate 2 and screwed into the threaded hole of the connecting seat 5 for positioning.

[0013] Compared with the prior art, the piston press-fitting fixture for connecting seat components described in this embodiment of the present invention has the following advantages: In the piston press-fitting fixture for connecting seat components provided in this embodiment of the utility model, the press-fitting bolt 3 penetrates the press-fitting plate 2 and contacts the press-fitting sleeve 1 for press-fitting, while the positioning bolt 4 penetrates the press-fitting plate 2 and is screwed into the threaded hole of the connecting seat 5 for positioning. Therefore, during use, only the middle press-fitting bolt 3 needs to be tightened to press the piston downwards, and the pressure is maintained by the press-fitting bolt 3. Finally, the snap ring can be installed normally from the side using snap ring pliers. Analysis shows that the piston press-fitting fixture for connecting seat components provided in this embodiment of the utility model maintains pressure during the press-fitting process and facilitates snap ring installation through the cooperation of the fixture and bolts. At the same time, this fixture has a simple structure, is easy to process, has high versatility, low cost, and is easy to operate, effectively reducing the workload of workers and increasing the efficiency of the fixture. Furthermore, relying on the bolts to maintain pressure and positioning frees up manpower for maintenance, ensuring the safety of operators.

[0014] In practical applications, such as Figure 1 As shown, the above-mentioned positioning bolts 4 may include two bolts, and the two positioning bolts 4 may preferably be located on both sides of the press bolt 3, thereby providing better positioning support.

[0015] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
