Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch equipment manufacturing, in particular to a guide block processing tool and processing equipment. Background Art

[0002] The guide block is a key component in high-voltage switch equipment. During the closing and opening process of the high-voltage switch, the guide block can ensure that moving parts such as the moving contact or moving blade move according to the predetermined trajectory and position, thereby achieving accurate electrical connection or disconnection. At the same time, since the high-voltage switch will generate large mechanical impact and friction during operation, the design of the guide block can also effectively reduce the wear of these impacts and friction on the moving parts, thereby extending the service life of the equipment. In addition, the guide block also plays the role of supporting and fixing other key components to ensure the stability and reliability of the entire switch structure. The guide block is a bonding part that is made by bonding two semi-finished parts, the guide plate and the insulating plate, together and then processed. The two semi-finished parts are bonded together with industrial glue, left to stand for a certain period of time, and cured. After curing, one surface of the guide plate and one surface of the insulating plate are processed. The drawing requires that the angle between the two processed surfaces must be 45° after processing. 0.2°. The closer the angle between the two faces of the guide block is to the theoretical angle, the better the guiding effect. Figure 1 , is a physical picture of the existing guide block. The right end face and the left inclined surface of the guide block are processing surfaces, and there are two through holes on the bottom surface of the guide block.

[0003] In the prior art, a V-shaped fixture and a vise are typically used for assembly. First, the vise is secured to the lathe's workbench, and the V-shaped fixture is placed on top of the vise. Depending on the part's shape, the parts can be grouped end-to-end. Depending on the size of the vise's jaws, a group can hold up to four parts. During machining, a group of four parts is first placed on the 90° V-shaped fixture, with the insulation plate machining surface facing the lathe spindle. The vise clamps the sides of the parts to machine the insulation plate surface. After machining a group of parts, the parts are manually adjusted in orientation and placed on the 45° V-shaped fixture, with the guide plate machining surface facing the lathe spindle. The vise clamps the sides of the parts to machine the guide plate machining surface. This method requires two assembly steps, each using different reference surfaces. This can lead to out-of-tolerance part angles during production. Furthermore, only four parts can be machined in one assembly, requiring two assembly steps to complete the finished product. This method presents problems with out-of-tolerance machining angles and low efficiency. Utility Model Content

[0014] Furthermore, equal-height blocks are respectively provided at both ends of the rotating seat, and the height of the equal-height blocks is consistent with the height of the guide blocks.

[0015] A guide block processing device comprises the above-mentioned processing tooling.

[0040] In the prior art, a V-shaped tooling and a vise are usually used for clamping.

[0043] The clamping and fixing device can be any type of clamping device, and it only needs to stably fix the guide block 6 on the rotating seat 1 for easy processing.

[0044] The tooling uses the bottom surface of the guide block 6 as the only reference surface, and relies on the rotation of the tooling to clamp and process the two processing surfaces of the guide block at a time, which can easily ensure the angular tolerance between the two processing surfaces and thus ensure the processing accuracy. At the same time, when the tooling is in use, it is only necessary to position and clamp the guide block 6 corresponding to the positioning pin hole 2, and then use the electric chuck to clamp the rotating seat 1, and then align the processing surface of the guide block 6, and simultaneously process a group of end faces of the guide block. After processing, the electric chuck rotates a certain angle to drive the tooling to rotate to the predetermined position, and process a group of 45° inclined surfaces of the guide block. Several guide blocks can be processed at a time, and the preparation stage for clamping the guide block 6 on the tooling is carried out outside the workbench, reducing the equipment downtime caused by loading and unloading parts on the workbench, giving full play to the advantages of vertical processing, reducing the frequency of guide block clamping, and reducing the labor intensity of workers. At the same time, the processing efficiency is high, providing a basis for continuous automated production of guide blocks, with a simple structure and easy implementation.

Several guide blocks 6 are arranged along a straight line and positioned sequentially on the flat surface of the rotating base 1. Adjacent guide blocks 6 are secured by threaded holes that engage screws 3 and washers 4, allowing the washers 4 to simultaneously press against the tops of two adjacent guide blocks 6. The guide blocks 6 at both ends of the rotating base 1 are secured by the washers 4 by simultaneously pressing against the contour blocks 5.

During compression, the washers 4 press against the tops of the guide blocks 6 and the contour blocks 5.

The rotary seat is rotated 180 °, and several guide blocks 6 are positioned and fixed on the plane on the other side of the processing tool in the same way to complete the positioning and installation of the guide blocks 6 to be processed.

Use the electric chuck to clamp the outer circle of the rotating seat 1 at one end, and use the top point to support the top hole of the rotating seat 1 at the other end to clamp the processing tooling.
