Problems solved by technology
Considering the manufacturing error, the use of the mandrel tool does not guarantee a high degree of coaxiality between the machining circular surface and the positioning circular surface
The coaxiality requirement that this type of tooling can guarantee is up to 0.03mm, which cannot meet the processing requirements of the workpiece for coaxiality

The invention discloses a workpiece positioning tool for a machine tool. The workpiece positioning tool for the machine tool comprises a cone, an inner cone sleeve, an elastic positioning ring, a gland, an elastic part, a rotation handle and a base. The cone comprises a first end face and a second end face, and the cross section area of the cone is gradually enlarged in the direction from the first end face to the second end face. The inner cone sleeve is arranged on the periphery of the cone in a sleeved mode. The elastic positioning ring is arranged on the periphery of the inner cone sleeve in a sleeved mode. The gland abuts against the end, close to the first end face of the cone, of the inner cone sleeve. The elastic part is connected between the gland and the cone in an abutted mode. The base is connected with the machine tool and connected with the second end face of the cone. With the arrangement, the high coaxiality of round faces at different positions can be ensured when the round faces at the different positions are machined with the workpiece positioning tool for the machine tool.
Description
technical field [0001] The invention relates to the technical field of lathes, in particular to a workpiece positioning tool for a lathe. Background technique [0002] During the machining process of the lathe, the workpiece needs to be fixed on the worktable of the lathe first, the worktable rotates to drive the workpiece to move together, the tool is fixed on the tool holder, and the tool holder is controlled during processing to realize the contact between the tool and the workpiece. The relative movement realizes the cutting function. Due to the rotary motion of the worktable, the processed surfaces are mostly round surfaces, such as shafts, holes, cones, etc. [0003] The processing requirements of many workpieces are multiple axes, holes, etc., and the process requires high coaxiality. For this kind of parts, it is necessary to realize the workpiece clamping once to complete multiple holes or axes with high coaxiality requirements. surface processing. [0004] Howev...
