Clamping device and method for machining slots of screw parts

Abstract

The present invention provides a clamping device and method for machining slots of screw parts. The device comprises a clamping base. The front of the clamping base is vertically processed with 1-2 rows of mounting holes, and the middle part of the mounting holes is provided with a As for the slot groove, a transition groove is provided on the side of the mounting hole close to the side of the clamping base, and a threaded hole is provided penetrating from the transition groove to the side of the clamping base, and a compression screw is arranged in the threaded hole. The method includes: inserting screws into the mounting holes of the clamping base in a row, screwing in the compression screws to compress the elastic clamping pieces, making the elastic clamping pieces close to the screws and compressing them, and at the same time produce uneven deformation, and tighten all the screws Press tight. The invention is simple and convenient to operate, and the labor intensity of workers is low; 1-2 rows of screws can be clamped at one time, and the processing efficiency is more than doubled; the processing cost is reduced and the yield is improved; product quality.

Description

technical field [0001] The invention relates to the technical field of screw slot processing, in particular to a clamping device and method for slot machining of screw parts. Background technique [0002] There are usually three processing methods for screw slots, one is direct molding, the other is milling, and the other is wire cutting. The mold is directly formed, the processing speed is very fast, the efficiency is high, and the cost is relatively small, but the disadvantage is that the two sides of the slot will produce "eight" characters, and the slot is not smooth; The word groove is flat and smooth, and there are no outer "eight" characters on both sides of the word groove, but it needs to be clamped with a clamping device during processing, otherwise it cannot be processed. The clamping methods mainly include bench vise clamping, three-jaw chuck clamping, and pressure plate clamping. When bench vise clamping and three-jaw chuck clamping are used, only one part can ...

Problems solved by technology

However, there is a certain error in the diameter of the screw, and the holding position is not the same, so it is easy to cause the screw with a larger diameter to be clamped, and the screw with a smaller diameter to loosen. , even the thread of the screw with a larger diameter will be damaged; secondly, the center of the positioning hole will have a certain central symmetry deviation during the upper and lower closing process, resulting in a certain degree of symmetry of the milled slot relative to the axis center. Deviation; and only one row of screws can be clamped, which is inconvenient to operate, and the smaller the screw, the more difficult it is to clamp
