Follow-up clamping device

Abstract

The invention discloses a follow-up clamping device for clamping and positioning pipe pieces. The device comprises a first bearing body, a second bearing body arranged on the first bearing body in a sliding manner, a clamping mechanism fixed on the first bearing body, and a bearing mechanism arranged on the second bearing body in a lifting manner, wherein the clamping mechanism comprises two groups of telescopic butting heads forming angles; the two groups of butting heads are symmetrically arranged left and right; the bearing mechanism comprises two rows of rollers symmetrically arranged left and right; rotating axle lines of the rollers in one group are parallel to one another, and are positioned in a same plane; two planes, where the rotating axle lines of the two rows of rollers are positioned, are intersected with each other; the pipe pieces are clamped between the two groups of butting heads and the two rows of rollers; and each of the rollers is arranged along the tangential direction of the pipe pieces. The pipe pieces are stably clamped and positioned through the two rows of rollers and the two groups of butting heads so as to provide guarantee to the technique precision of following operations for the pipe pieces; and the device has a reasonable structure, is easily and reliably adjusted, and is suitable for the pipe pieces with different pipe diameters.

Description

technical field [0001] The invention relates to a device for clamping and positioning pipe fittings, in particular to a follow-up clamping device. Background technique [0002] as attached figure 1 and attached figure 2 As shown, the clamping device used for clamping and positioning the pipe fittings in the traditional technology first supports the pipe fittings through the lower supporting parts, and then controls the corresponding four cylinders at an angle of 90 degrees to each other through four cylinders. The clamping head clamps the pipe fittings, so that the weight of the entire pipe fitting is completely borne by the two pressing heads below. Generally, the quality of the pipe fittings is relatively large. When the pipe fittings are cut and other operations are performed, the center of gravity of the pipe fittings will often occur. Deviation, and it is difficult to re-adjust the center, it will lead to the loosening of the clamping head in the corresponding direc...

Problems solved by technology

[0002] As attached Figure 1 and attached Figure 2 It is shown that the clamping device used for clamping and positioning the pipe fittings in the traditional technology first supports the pipe fittings through the supporting parts below, and then controls the corresponding four resisting parts at an angle of 90 degrees through four cylinders. The clamping head clamps the pipe fitting, so that the weight of the entire pipe fitting is completely borne by the two lower clamping heads. Generally, the quality of the pipe fitting is relatively large. When cutting the pipe fitting, etc., the center of gravity of the pipe fitting will often deviate. , and it is difficult to re-adjust the center, it will cause the clamping head in the corresponding direction to loosen and can no longer clamp the pipe stably, making it difficult to meet the accuracy requirements in subsequent operations
