Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] like figure 1 Shown, the present invention comprises cylinder 1, first, two connecting rods 6,7 and upper and lower clamping block 4,5, and cylinder 1 is hinged on cylinder support 2. One end of the cylinder connecting rod 3 is connected with the output end of the cylinder 1, and the other end is respectively connected with one end of the first and second connecting rods 6 and 7 through pin shafts. The cylinder connecting rod 3 reciprocates left and right relative to the cylinder 1, and can reciprocate left and right relative to the cylinder support 2, and can also rotate. The lower clamping block 5 is interlocked with the other end of the first connecting rod 6 through a pin shaft, and the other end of the second connecting rod 7 is hinged on the fixing base 8 . The upper clamping block 4 is fixed on the frame, and the lower clamping block 5 can rec...

Abstract

The invention relates to a clamp, in particular to a clamping device which is applicable for a rotation body with external surfaces of rotating body and used for screwing threads; the clamping device comprises a cylinder, a first connecting rod, a second connecting rod, an upper clamping block and a lower clamping block; the cylinder is arranged on a cylinder supporter; one end of the cylinder connecting rod is connected with the output end of the cylinder and the other end thereof is respectively connected with one end of the first connecting rod and the second connecting rod by a pin shaft; the lower clamping block is connected with the other end of the first connecting rod by the pin shaft; the other end of the second connecting rod is pivotally connected on the fixed base; the cylinder is pivotally connected on the cylinder supporter; the cylinder supporter is arranged on a frame; the upper clamping block is fixed on the frame; the lower clamping block can reciprocate upwards and downwards correspondingly to the upper clamping block; the fixed base is arranged on the frame; the clamping parts of the upper clamping block and the lower clamping block are respectively provided with a concave trough; the clamping device has large clamping force, uses a connecting rod reinforcement mechanism and the driving cylinder with small diameter so as to realize large clamping force, firmly and reliably clamps the workpiece, saves the operation space and site, and has small volume, light weight and low manufacturing cost.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamping device suitable for thread tightening whose outer surface is a rotating body. Background technique [0002] At present, constant torque tightening has been more and more used in various production fields. The existing workpiece clamping methods can be divided into vertical clamping and horizontal clamping according to different workpiece placement methods. Horizontal clamping usually adopts the method of direct pressing up or down. The outer surface of the workpiece is clamped by the fixture, and one end is threaded, which can tighten other workpieces; when the clamping force of the fixture is large, the solution is usually Increase driving force. And when it is necessary to improve production efficiency, online automatic clamping and save operating space and operating site, and require a large clamping force, it is difficult to meet the work requirements by using the above-mentioned form....
