Description

Technical Field

[0001] This utility model relates to a testing device for the elastic force of an elastic retaining ring, specifically a testing fixture for the elastic force of an elastic retaining ring used in a hole. Background Technology

[0002] Elastic retaining rings for bores are mainly used to fix parts within bores, such as in mechanical devices. Installed within the groove of a round hole, they prevent axial displacement of shafts, bearings, and other parts, serving an axial positioning function and ensuring stable positioning during operation. Therefore, elastic retaining rings for bores are required to have a certain elasticity. Elasticity testing is a common method for detecting the elasticity of elastic retaining rings for bores. Some retaining rings require clamping two holes to a certain size, with the pressure conforming to a specific range, or clamping two holes together, with the pressure conforming to a specific range. Currently, handheld installation pliers cannot measure the elasticity of elastic retaining rings for bores. Utility Model Content

[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide a testing fixture for the elastic force of a retaining ring for a hole, thereby solving the problem that handheld installation pliers cannot measure the elastic force of a retaining ring for a hole.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A testing fixture for the elastic force of a retaining ring for holes includes an upper base and a lower base, which are rotatably connected at one end. An upper fixed shaft is provided at the other end of the upper base, and a lower fixed shaft is provided at the other end of the lower base. The upper fixed shaft and the lower fixed shaft pass through two holes at the end of the retaining ring for holes.

[0006] Preferably, an elastic retaining ring placement groove is formed on the lower base, the elastic retaining ring placement groove is surrounded by a bottom surface, a vertical side surface and an arc-shaped side surface, the vertical side surface and the arc-shaped side surface are disposed on the bottom surface, the arc-shaped side surface intersects with the vertical side surface, and the lower fixing shaft is disposed on the vertical side surface.

[0007] Preferably, the vertical side and the side of the upper base on which the upper fixed axis is located are on the same plane.

[0008] Preferably, the upper substrate is made of aluminum alloy.

[0009] The positive and beneficial effects of this utility model are as follows:

[0010] 1. The tooling for testing the elastic force of the retaining ring for holes is easy to assemble, disassemble and install, and measure, thus solving the problem that handheld installation pliers cannot measure the elastic force of the retaining ring for holes. Attached Figure Description

[0015] The present invention will be further described below with reference to some specific embodiments.

[0016] See Figure 1 and Figure 2 A test fixture for testing the elasticity of a retaining ring for holes includes an upper base 1 and a lower base 2. A connecting hole is opened at one end of the upper base 1 and the lower base 2, and a cylindrical pin passes through the connecting hole. The upper base 1 and the lower base 2 are rotatably connected by the cylindrical pin. An upper fixed shaft 3 is fixed at the other end of the upper base 1, and a lower fixed shaft 4 is correspondingly fixed at the other end of the lower base 2. The retaining ring for holes 6 is a ring shape with an opening, and holes are opened at both ends. The upper fixed shaft 3 and the lower fixed shaft 4 pass through the two holes at the ends of the retaining ring for holes 6.

[0017] Furthermore, an elastic retaining ring placement groove 5 is formed on the lower base 2. The elastic retaining ring placement groove 5 is surrounded by a bottom surface 51, a vertical side surface 52, and an arc-shaped side surface 53. The vertical side surface 52 and the arc-shaped side surface 53 are set on the bottom surface 51. The vertical side surface 52 is perpendicular to the bottom surface 51, and the arc-shaped side surface 53 intersects with the vertical side surface 52. The lower fixed shaft 4 is fixed on the vertical side surface 52. The elastic retaining ring placement groove facilitates the installation of the elastic retaining ring and the observation of the deformation of the elastic retaining ring. The arc-shaped side surface is set away from the lower fixed shaft to prevent the elastic retaining ring from deforming and colliding with the inner wall of the placement groove during the elastic force test, which would affect the test results.

[0018] Furthermore, the vertical side 52 and the side of the upper base 1 that is fixed to the upper fixed shaft 3 are located on the same plane, and the hole is installed with an elastic retaining ring in its natural state to ensure accurate force measurement.

[0019] Furthermore, the upper substrate 1 is made of aluminum alloy and its volume is as small as possible to avoid the influence of the test fixture's own weight on the test force measurement.

[0020] The method for using the testing fixture for the elastic force of the hole retaining ring of this utility model is described in [reference needed]. Figure 3The upper and lower fixed shafts pass through the two holes at both ends of the elastic retaining ring, which is then installed onto the testing fixture. The testing fixture is then placed on the worktable of a spring elasticity testing machine or an electronic universal testing machine. Pressure is applied to the upper substrate through displacement control, and the value displayed by the force sensor is the elastic force of the retaining ring at this time.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
