Fixtures for Turning Ball Head Shaft Parts

Abstract

The invention discloses a fixture for a turning ball head shaft type part. The fixture comprises a fixture body, a supporting body and a gland; the supporting body is of a stepped shaft structure, thesmall-diameter segment of the back portion of the supporting body is inserted into a guiding blind hole formed in the front end face of the fixture body in a clearance fit mode, the large-diameter segment of the front portion of the supporting body is inserted into a guiding hole formed in the back end face of the gland in a clearance fit mode, and the guiding hole comprises a circular guiding portion arranged at the front end and a conical clamping portion arranged at the back end; a conical positioning groove is formed in the front end face of the supporting body, and a ball head of the part is fixedly clamped through the conical positioning groove and the conical clamping portion; and the gland is provided with an axial through hole which communicates with the guiding hole and is usedfor allowing a part shaft body to penetrate. According to the fixture for the turning ball head shaft type part, the workpiece ball head is fixed to the interior of the fixture through relative extrusion of the supporting body and the gland, a compression spring between the supporting body and the fixture body can ensure that a workpiece is always fixedly compressed, the shaft body of the workpiece stretches out of the gland, subsequent machining is convenient, and the fixing mode is reliable and stable.

Description

technical field [0001] The invention relates to the field of ball head shaft processing, in particular to a fixture for turning ball head shaft parts. Background technique [0002] Ball head shaft parts are widely used in the machinery industry. As a joint, the ball head can rotate in all directions to provide a great degree of freedom for the parts. In machining, it is often encountered such as figure 1 For the processing of the ball head parts shown, the ball head is generally processed first, and then the other end of the part is processed. Due to the particularity of the shape of the part, the general fixture with a smooth ball head cannot be clamped at all, which will bring a lot of trouble to the subsequent processing of the part. come difficult. Contents of the invention [0003] The invention overcomes the existing defects and provides a fixture for turning ball head shaft parts, which is firm in installation, fast and convenient in clamping workpieces, and facili...
