Embodiment
[0028] Embodiment: a kind of special tooling for cylinder bore turning, such as figure 2 As shown, it includes the insertion rod 1, the connecting rod 2 and the limit tube 3 which are coaxially fixed in sequence. Diameter, the diameter of the insertion rod 1 is greater than the diameter of the limit tube 3, and a step 11 is formed between the insertion rod 1 and the connecting rod 2; the outer diameter of the limit tube 3 matches the inner diameter of the cylinder 7, and the connecting rod 2 is close to the insertion One end of the rod 1 is provided with a support platform 21, the support platform 21 has the same diameter as the limit tube 3, and the support platform 21 is chamfered at one end facing the limit tube 3, so that the support platform 21 and the connecting rod 2 make a smooth transition.
[0029] A plurality of adjustment grooves 31 are evenly opened on the pipe wall of the limiting pipe 3 along its axis, and the adjusting grooves 31 penetrate the end of the limit...

The invention discloses a special tool for cylinder barrel turning. The special tool comprises an insertion rod, a connecting rod, a limiting pipe, and a fixed casing pipe sleeving the connecting rodand the limiting pipe; the fixed casing pipe is fixed on the insertion rod; gaps are formed between the fixed casing pipe and the limiting rod, the limiting pipe; a round table type adjusting block ismovably connected into the limiting pipe; the internal shape of the limiting pipe is matched with the adjusting block; multiple adjusting grooves are formed in the axis of the pipe wall of the limiting pipe; an ejecting piece is inserted in the adjusting block; and the ejecting piece is in threaded fit with the connecting rod to drive the adjusting block to move into the limiting pipe. The special tool for cylinder barrel turning can stably clamp cylinder barrels, and reduces the deformation of barrel walls of the cylinder barrels.
Description
technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a special tooling for turning cylinder barrels. Background technique [0002] At present, the processing of the cylinder barrel is done by honing the inner hole of the cylinder barrel first, and then the length, chamfering and thread turning of the cylinder barrel are performed. Such as figure 1 As shown, the thickness of the wall of the existing cylinder 7 is relatively thin, and it is easy to deform the wall of the cylinder 7 when clamping on a lathe, so that deformation problems such as bell mouth are likely to occur when the cylinder 7 is processed at the end of the inner step hole, and it is difficult to Meet the requirements of machining accuracy. Contents of the invention [0003] The object of the present invention is to provide a special tool for turning the cylinder, which can clamp the cylinder stably and reduce the deformation of the cylinder wall. [00...
