Clamping clamp for circumferential uniform machining of grooves in cam surface of swing sliding base

Abstract

The invention discloses a clamping clamp for the circumferential uniform machining of grooves in the cam surface of a swing sliding base. A rotating shaft is connected to a seat body in a rotating manner, the rotating shaft is connected with a turn plate through a key, and two locating holes are arranged in the turn plate. Locating nails penetrate through connecting holes in a lower connecting plate and extend into the locating holes. A pressing plate is fixed to the turn plate through a fastening screw, the fastening screw is tightened, and the pressing plate is pressed on the lower connecting plate. A reference base is fixedly connected to the seat body, and the reference base is located at the outer side of the turn plate and coaxially arranged with the turn plate. An even number of reference nails are inserted to the circumferential wall of the reference base, steel balls are connected to the circumferential wall of the turn plate through the elastic support of springs, and the steel balls are pressed against the reference nails. A fixed plate is fixedly connected to the turn plate, butterfly screws are connected to the fixed plate through threads, and the bottom ends of the butterfly screws are pressed against the reference nails against which the steel balls are pressed. The clamping number is low, the repeated locating of the swing sliding base is avoided, and the machining efficiency is greatly increased.

Description

Technical field: [0001] The invention relates to a clamping fixture which is machined with evenly distributed grooves on the cam surface of an oscillating sliding seat. Background technique: [0002] The shape of the swing slide is extremely complex (such as figure 1 ), when the milling machine is processing the groove 100 to be processed on the cam surface 14 in the swing slide, it adopts a step-by-step processing method, so it needs to clamp the part multiple times, so the processing efficiency is low, and at the same time due to Multiple clamping and inconsistent positioning surfaces lead to error accumulation and affect the improvement of machining accuracy. Invention content: [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a clamping fixture in which grooves are uniformly distributed in the circumferential direction of the cam surface of the swing slide seat. [0004] The technical solution adopted in the ...
