Description

Technical Field

[0001] The utility model relates to a bushing test fixture structure. Background Art

[0002] The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to a ring sleeve that acts as a gasket. In the field of valve application, the bushing is inside the valve cover, and generally corrosion-resistant materials such as polytetrafluoroethylene or graphite are used for sealing. For example, a bushing pressure deformation detection device with patent number CN216049795U, the cylinder drives the upper movable pressing seat to rise and reset, and the pressing tooling is opened, the standard measuring tool can be removed, and the detected bushing is placed in the positioning groove, and the cylinder is started again. The driving end of the cylinder drives the upper connecting plate and the upper movable pressing seat to descend, and the cylinder pressure is adjusted to 0.2MPA, and the bushing can be pressed by the lower fixed pressing base and the upper movable pressing seat. The two-hand start switch is started again to control the start of the electronic press, so that the pressure head of the electronic press is pressed down and pressed onto the pressure head touch plate, and the contact is pressed to control the pressurization until the pressure of the electronic press reaches 500N, and the pressing tooling is pressed to a position by the upper movable pressing seat. At this time, the distance moved by the upper movable pressing seat can be measured by the distance meter, which is the deformation of the bushing.

[0003] This embodiment can satisfy the bushing pressure deformation detection device to measure the bushing pressure and ensure the qualified rate of the product, but it has the following defects:

[0004] 1. The bushing is fixed and placed by setting the pressing tool, which is convenient for the electronic press to perform pressure testing on the bushing.
