Problems solved by technology
[0002] The pressure ring is one of the parts on the converter of the microscope, which is a thin-walled cylinder; there is a pressure ring, the outer circle and end face of the pressure ring have high requirements for dimensional accuracy and position accuracy, and the inner circle has a coaxiality with the outer circle. Requirements; the current processing method of the pressure ring is to process the clamping piece by piece. The processing steps are: 1. Roughly turn the inner hole, 2. Turn around, use the inner circle to locate the outer circle and end face of the rough and finish turning; 3. Use the outer circle Circular positioning of the inner circle of fine turning; the above processing method uses three sets of turning fixtures, which have the problems of low efficiency and high processing cost in the production process

The invention discloses a turning clamp for pressing rings and relates to the technical field of clamp manufacturing. The turning clamp comprises a barrel body, wherein the barrel body is provided with a flange connection portion. The barrel body is internally provided with a sleeve portion. An inner hole of the sleeve portion is provided with a pressing sleeve. One end of the pressing sleeve is adjacent to a locating ring, and the other end of the pressing sleeve is provided with a pressing block locating portion, wherein the pressing block locating portion extends out of the inner hole of the sleeve portion. Multiple pressing claws are arranged between the sleeve portion and the side wall of the barrel body and each connected to a locating disc in a hinged manner. The locating disc is connected with the movable end of an air cylinder through a pull rod. Compared with the prior art, by means of the turning clamp, massive turning machining can be conducted on inner circles of the multiple pressing rings; machining efficiency is improved; and machining cost is lowered.
Description
technical field [0001] The invention relates to the technical field of clamp manufacturing, in particular to a vehicle clamp used for a pressure ring on a microscope. Background technique [0002] The pressure ring is one of the upper parts of the microscope converter, which is a thin-walled cylinder; there is a pressure ring, the outer circle and end face of the pressure ring have high requirements for dimensional accuracy and position accuracy, and the inner circle has a coaxiality with the outer circle. Requirements; the current processing method of the pressure ring is to process the clamp one by one. The processing steps are: 1. Roughly turn the inner hole; Circular positioning of the inner circle of fine turning; the above processing method uses three sets of turning fixtures, which have the problems of low efficiency and high processing cost in the production process. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
