[0027] Such as figure 1 , figure 2 with image 3 As shown, the body of the insulated strain clamp in the prior art is formed by casting aluminum material.

The upper two sides of the insulating strain clamp are symmetrically provided with wire clip ears 104. The insulating strain clamp after casting needs Machining the ear 104 of the wire clip, that is, process the threaded blind hole at the ear of the wire clip, figure 1 with image 3 The X-lead in the pointed out that the threaded blind hole is processed and formed. The threaded blind hole is used to connect the pull plate to form an insulating strain clamp assembly for the drainage of the overhead transmission line. When the existing ordinary drilling machine is used for processing, it is necessary Positioning the insulation strain clamp, there is no special tooling for clamping and positioning it. Due to the shape of the insulation strain clamp and the arrangement of the ribs and lugs, the clamping and positioning of the insulation strain clamp is very difficult During machining, it is easy to appear asymmetry in the threaded blind holes of the clip ears on both sides. For example, the threaded blind holes on both sides have different axes, and the threaded blind holes are inclined. When the overhead transmission line is drained The insulating strain clamp cannot realize the above-mentioned functions. Therefore, this traditional processing method results in poor product quality, high rejection rate and low labor efficiency of the insulated strain clamp.
