Shear mouth processing mechanism for pinchers

Abstract

The invention relates to a shear mouth processing mechanism for pinchers. A machine frame is provided with three vertical locating and locking screws, the locating and locking screws are sleeved withclamping lower plates and clamping upper plates, the pinchers are arranged between the clamping lower plates and the clamping upper plates, and the pinchers passes through locating and locking screwson the clamping upper plates to be locked through locating and locking nuts. Arc material-placing locating blocks matched with the rotating portions of the pinchers are arranged on the clamping lowerplates, and the clamping block portions of the pinchers and handle rear portions are beyond the clamping lower plates and the clamping upper plates. Shear mouth processing devices matched with the clamping block lower portions and handle clamping devices matched with the handle rear portions are arranged on the lower portion of the machine frame. The shear mouth processing mechanism for the pinchers clamps the pinchers through the clamping lower plates and the clamping upper plates, the material-placing locating blocks on the clamping lower plates can realize the locating of the rotating portions of the pinchers, the handle clamping portions are matched to clamp the handles of the pinchers, the whole locating of the pinchers can be realized, and the shear mouth processing devices adopt a processing method from bottom to top can conveniently process falling materials of chippings.

Description

technical field [0001] The invention relates to the field of pliers processing equipment, in particular to a notch processing mechanism for pliers. Background technique [0002] Pliers are a commonly used hand tool with a wide range of applications, and there are various types according to specific needs, such as figure 1 As shown, it is the most conventional pliers, which includes two halves consisting of a handle 1, a rotating part and a pincer block 2, and a centering shaft 3 is sleeved in the center of the rotating part of the two halves. Parts are provided with notches and bayonets. In the processing engineering, the two halves must first be cast, and then the notches are processed by a milling machine or a grinder, and then the two halves are assembled. Notch processing, its positioning and clamping operations are simple, and can ensure the processing accuracy of a single half block, but when the two half blocks are assembled, it is easy to cause a large error when th...

[0002] Pliers are a commonly used hand tool with a wide range of applications, and there are various types according to specific needs, such as figure 1 As shown, it is the most conventional pliers, which includes two halves consisting of a handle 1, a rotating part and a pincer block 2, and a centering shaft 3 is sleeved in the center of the rotating part of the two halves. Parts are provided with notches and bayonets. In the processing engineering, the two halves must first be cast, and then the notches are formed by a milling machine or a grinder, and then the two halves are assembled. Notch processing, its positioning and clamping operations are simple, and can ensure the processing accuracy of a single half block, but when the two half blocks are assembled, it is easy to cause a large error when the two notches are matched due to the errors in their respective processing , affecting the quality of the pliers, so it is urgent to design a notch processing mechanism that can facilitate the precise positioning of the assembled pliers
