Embodiment Construction

[0019] Such as Figure 1 to 3 Shown

[0020] The positioning tool includes a positioning body 1 and an expansion assembly.

[0021] The outer wall of the positioning body 1 fits the contour of the inner hole of the hydraulic cylinder barrel 5. The outer wall of the positioning body 1 extends with a retaining ring 11 that matches the front face of the hydraulic cylinder barrel 5, and the rear face of the positioning body 1 is provided with an expansion groove 12 and an expansion groove 12 The direction is consistent with the axial direction of the positioning body 1, the expansion groove 12 has a threaded hole 13 on the front side groove wall, the rear circumferential groove wall of the expansion groove 12 has a taper α, and the positioning body 1 has a circumferential uniform distribution on the rear surface Two expansion joints 14 extending axially along the positioning body 1 and penetrating the rear of the positioning body 1, a thin-walled expansion clamp that can be expanded o...

Abstract

The invention provides a novel hydraulic cylinder barrel machining and positioning tool comprising a positioning body and an expansion assembly. The outer wall of the positioning body is matched withthe outline of an inner hole of a cylinder barrel of a hydraulic cylinder, a baffle ring matched with the front end face of the cylinder barrel of the hydraulic cylinder extends from the outer wall ofthe positioning body, an expansion groove is formed in the rear end face of the positioning body, a threaded hole extending towards the interior of the positioning body is formed in the groove wall of the front side of the expansion groove, the circumferential groove wall at the rear part of the expansion groove has taper, and a plurality of expansion gaps which extend axially along the positioning body and penetrate through the rear part of the positioning body are arranged on the rear end face of the positioning body; and the expansion assembly at least comprises a bolt and a frustum block,the taper of the side wall of the frustum block is matched with the taper of the circumferential groove wall at the rear part of the expansion groove, and the bolt penetrates through the frustum block and is matched with the threaded hole of the expansion groove. The positioning tool has the advantages that the positioning tool adopts the inner hole of the cylinder barrel for positioning, the processing of the inner hole, trenches and threads can be finished by one-time clamping, the processing efficiency is high, no reference conversion exists, and the processing precision is improved.

Description

Technical field [0001] The invention relates to a positioning tool, in particular to a novel hydraulic cylinder cylinder barrel processing positioning tool. Background technique [0002] At present, most of the inner holes of the blanks before turning of the general hydraulic cylinders are processed. The existing positioning methods mostly use the chuck and the center frame to cooperate, and the process circle is converted into the inner hole reference to perform the inner hole and groove And thread processing. This kind of processing positioning method causes many procedures, long processing time, and there is a conversion of the reference, and the processing accuracy will be reduced due to the increase of the number of reference replacements. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a novel hydraulic cylinder cylinder barrel processing positioning tool with reasonable structure and convenient use. [0004] In ord...
