Tool clamp suitable for turning end face outer circle of double-sided boss groove wheel at one step

Abstract

The invention discloses a tool clamp suitable for turning the end face outer circle of a double-sided boss groove wheel at one step, and mainly relates to a clamp. Each supporting clamp body comprisesa frame rod and a supporting block, one end of the frame rod is detachably and fixedly connected with clamping jaws of a three-jaw chuck, and the supporting block is located on one side, away from the clamping jaws, of the frame rod. A positioning device is arranged on one of the supporting clamp bodies. The tool clamp has the beneficial effects that two A end faces, two B outer circles and two Cend faces on the two sides can be subjected to turning finish machining under the condition of clamping and positioning at one step, the clamping and positioning mode is simple, the machining time ofthe working procedure is greatly shortened, and the production efficiency is improved; and the clamp in the clamping mode is not in contact with the to-be-machined faces, the machining faces are notdamaged, and the finish machining quality is improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a tooling fixture suitable for the outer circle of the one-time car end face of a grooved wheel with a double-sided boss. Background technique [0002] As attached in the manual Image 6 For the double-sided boss sheave part shown, the A end face, B outer circle, and C end face of this part need to be turned and finished, and there are a set of A end face, B outer circle, and C end face on both sides of the sheave. The manufacturer adopts the following processing methods when performing turning finishing on two A end faces, two B outer circles, and two C end faces: [0003] First, the three-jaw chuck clamps the boss on one side, and performs turning and finishing on the A end face, B outer circle, and C end face on the other side; then remove the part from the three-jaw chuck, turn the part over, and then use three The jaw chuck clamps the boss on the other side, and performs turning finishing on th...

Problems solved by technology

[0004] The above-mentioned processing method requires two times of clamping, positioning and turning, which increases the processing time of this process and causes parts to accumulate in this process, which greatly affects the processing efficiency; and when the second clamping is performed, the three-jaw chuck clamps The outer circular surface of the boss processed by turning is very easy to damage the outer circular surface of the boss and reduce the quality of finishing
