Clamp for screw rod machining and grinding

Abstract

The invention discloses a clamp for screw rod machining and grinding. The clamp comprises four corner supporting legs, and a working plate is fixedly connected to the tops of the four corner supporting legs. A supporting rod is fixedly connected to the right side of the top of the working plate, and a transverse plate is fixedly connected to the top of the supporting rod. An adjusting rod penetrates through the top of the transverse plate. According to the clamp for screw rod machining and grinding, through arrangement of a fixing sleeve, cooperative use of the transverse plate, the adjustingrod, a first bearing, a U-shaped clamping piece, a movable rod, a fixed plate, a telescopic rod, a tension spring, a second bearing, a sliding rod, a sliding sleeve, a pull rod, a clamping piece and aclamping plate, the screw propelling principle of the adjusting rod and the transverse plate, elastic acting force of the tension spring and the vertical displacement of the movable rod, the effect that the fixing sleeve vertically moves is achieved, through the effect of rotating clamping of the clamping piece and the sliding sleeve, the effect that a machined screw rod is fixed is achieved, andthus, the effects that machined screw rod is more firmly fixed, and rotation and deviation cannot occur are achieved.

Description

technical field [0001] The invention relates to the technical field of thread processing tools, in particular to a clamp for screw processing and grinding. Background technique [0002] A cylinder with spiral grooves cut on the outer surface of the screw or a cone cut with spiral grooves on the conical surface is threaded with parts such as nuts connected with thread grooves. It is a basic part used to fix or reinforce mechanical equipment. Its characteristics are: The production and processing are simple, and the usability is wide. Among them, the screw rod needs to be polished during the processing process, and it is usually fixed by a clamp, and then the screw rod grinding process is started. However, when the existing clamps are used to fix the screw rod, the screw rod is generally fixed by the cooperation of the pressure spring and the clamp, so that the processed screw rod is easy to rotate and shift when processing, thus causing the screw rod to be in the process of g...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a fixture for screw processing and grinding, which solves the problem that when the existing fixture fixes the screw, it usually fixes the screw through the cooperation of a pressure spring and a clip, so that the screw can be fixed during processing. At the same time, the processed screw is easy to rotate and misalign, which leads to low precision of the screw during grinding, which affects the quality of the screw
