Description

Swift sectional fixture of sealing washer for hole

Technical Field

The utility model relates to an anchor clamps installation technical field especially relates to a swift sectional fixture of sealing washer for hole.

Background

In the sealing element industry, the rubber sealing element is generally well installed due to good elasticity and free expansion and contraction. The plastic sealing element is inferior to rubber in hardness, elasticity, flexibility and the like, so that the plastic sealing element needs to be designed with consideration for installation. The polytetrafluoroethylene sealing element has certain elasticity but poor elasticity, and the sealing element produced by the material can be not easily assembled in a closed groove, particularly the closed groove for a hole. Therefore, for this type of product, a good mounting jig is very obvious for improving the mounting efficiency.

At present, two common installation modes of polytetrafluoroethylene products in closed grooves for holes are provided, wherein one mode is manual installation; and the other is auxiliary installation by using a traditional installation clamp.

As shown in FIG. 1: manual installation drawing, fig. 2: the conventional mounting jig has a problem in products in which either of the above methods is used.

The piston needing to be provided with the sealing element at present is not just the same as a common piston, but is provided with 8 grooves side by side, one end of the piston is closed, and the distance between the innermost groove and the end surface reaches up to 230 mm. (see FIG. 3).

When using a conventional mounting fixture, it is difficult to manufacture the fixture in practice because the fixture must be extended with the mounting mandrel in the fixture in order to accommodate the shape and size of the piston itself so that the fixture can cover no groove. Firstly, the right side 0.3 thick part of the clamp which is made of engineering plastics is too long to be processed by a common method, and secondly, the thin part which is long and thin is easy to be damaged even if the thin part is processed when in use.

The manual installation has two problems, 1, in the installation process, the sealing ring can be installed in the groove after being enlarged actually, but in the stretching process, excessive stretching or uneven stretching is easily caused, so that the piston can not be installed in the cylinder body smoothly during further installation or the sealing performance of the sealing element is influenced; 2. the work efficiency of pure manual installation is very low.
