A clamping and positioning tool for solid-sealed poles

Abstract

The invention discloses a clamping and location fixture for a solid-encapsulated post. According to the invention, a location shaft used for being inserted in a first line-outgoing hole of the solid-encapsulated post in a fit manner is arranged on a location support to realize coaxial location fit, a fixed support body used for realizing gap sleeving for a second line-outgoing hole of the solid-encapsulated post, a movable support body moving in the radial direction of the second line-outgoing hole relative to the fixed support body through a guide structure so as to tightly support the second line-outgoing hole, and a locking mechanism used for locking the tightly supported movable support body, are arranged on a location support. The clamping and location fixture disclosed by the invention is capable of forming a whole after clamping the solid-encapsulated post and then assembling the solid-encapsulated post, and location during installation is carried out by virtue of an assembly and location datum on the fixture, so that scraping and collision of the solid-encapsulated post can be avoided; and the high-accuracy line-outgoing holes in the solid-encapsulated post are clamped and matched with corresponding location structures on the fixture, so that dimensional accuracy can be ensured, assembly efficiency can be increased, and collision damages of the post can be avoided.

Description

technical field [0001] The invention relates to a clamping and positioning tool for a solid-sealed pole installed in electrical equipment. Background technique [0002] The solid-sealed poles that need to be positioned and installed in electrical equipment such as figure 1 As shown, it includes a cylinder 4, and the cylinder 4 is fixedly connected with two upper and lower outlet seats distributed up and down, the upper outlet seat is provided with an upper outlet hole 1, and the lower outlet seat is provided with a lower outlet hole 2, There is also a base 41 at the bottom of the cylinder 4, and the bottom surface of the base 41 is provided with a bottom mounting hole for fixing the solid-sealed pole in related equipment. [0003] Since the solid-sealed pole is a product whose exterior is cast with epoxy resin, the appearance of the solid-sealed pole casted by epoxy resin is relatively smooth and it is easy to scratch and cause scratches. If the scratch is minor, it needs t...

Problems solved by technology

Although the solid-sealed pole has high dimensional accuracy requirements in production, in the actual production process, epoxy resin casting will shrink during the cooling process, and the size will produce certain uncertain distortions. In order to be able to adapt to Due to certain deformation and machining error, the mounting hole on the bottom surface of the solid-sealed pole has a large clearance margin, which will cause a certain gap between the bolts on the chassis and the mounting hole, which cannot play a necessary role in the pole. In this way, a large assembly size error will be generated, so that some key dimensions of the pole positioning cannot be guaranteed, which will affect the matching accuracy of the pole and other components in the electrical equipment, and greatly reduce the pole in the main switch. The electrical performance of the circuit reduces the reliability and electrical life of the pole to a certain extent.
