Problems solved by technology

During processing, it is necessary to fix the index plate A, counterweight A, index plate B and counterweight B to the workpiece with screws, and then fix the index plate A, counterweight A, and index plate after the drilling is completed. B and the counterweight block B are fixed to the workpiece by loosening the screws, so that the processing of different workpieces is realized repeatedly, which makes the process more complicated and low work efficiency in actual use; On the workpiece, it is difficult to guarantee the positioning accuracy of the workpiece, and may cause damage to the surface of the workpiece

Abstract

The invention relates to the field of mechanical manufacturing, in particular to a lathe processing eccentric deep hole clamp which comprises a clamping sleeve. The center line of the clamping sleeve is coaxial with the center line of a lathe main shaft. The front end and the rear end of the clamping sleeve are provided with a front eccentric flange and a rear eccentric flange respectively. An installation hole I is formed in the front eccentric flange and an installation hole II is formed in the rear eccentric flange. The center line of the installation hole I and the center line of the installation hole II are coaxial with the center line of a workpiece to be processed. A balancing weight is arranged on the outer side of the clamping sleeve. The lathe processing eccentric deep hole clamp has the advantages of being capable of conveniently and rapidly detaching and assembling the workpiece, high in processing precision, little in damage to the workpiece and suitable for batched eccentric deep hole processing.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a lathe machining eccentric deep hole fixture. Background technique [0002] In the field of mechanical processing, when the ratio of the diameter of the hole to the depth of the hole exceeds 1:25, it belongs to the scope of deep hole processing. The hole gun drill is processed on a lathe, or a special deep hole drilling machine is used for drilling; but when the position of the deep hole is eccentric to the center line of the slender shaft, most of the holes are drilled on a boring machine with a gun drill, but the boring machine The rotation speed is low, and it is necessary to add a special speed increaser for the gun drill to increase the rotation speed of the spindle. Compared with the ordinary lathe, the value of the boring machine is much higher than that of the lathe. The situation of "pulling a small cart" will obviously increase the manufacturing cost, which is ...
