Description

A multifunctional clamping device for turning

technical field

The invention relates to a turning tool for rotating parts, in particular to a multifunctional clamping device for turning.

Background technique

There are a large number of irregular rotating parts in the field of machinery manufacturing. The inner and outer circles of these irregular parts have coaxiality requirements, which cannot be directly clamped on a lathe for one-time processing to ensure the coaxiality requirements. For post-processing, it is difficult to align the datum, and there will be accumulated errors after multiple alignments, which makes the processing efficiency of the parts low and the accuracy difficult to meet the assembly requirements.

Contents of the invention

The object of the present invention is to provide a device for turning rotating parts with simple structure and capable of realizing multiple functions.

The technical solution of the present invention is: a multi-functional clamping device for turning, which is characterized in that: the device includes a mandrel 1, a compression nut 2, a washer 3, a pressure plate 4 and a bolt 5, and the mandrel 1 is threaded on the circumferential surface, and a boss is provided on the inner circumferential surface of one end of the compression nut 2, and a washer 3 is installed on the boss;

The compression nut 2 is mounted on the mandrel 1 through threaded connection; the end surface of the mandrel 1 has a screw hole, the bolt 5 is installed in the screw hole, and the pressure plate 4 is set on the bolt 5 .

Beneficial effects of the present invention: through precise positioning of the mandrel, the parts are fixed on the lathe by washers, compression nuts and bolts for processing, and at the same time, different parts of the compression parts can be processed by replacing the gaskets, compression nuts and bolts. This device It solves the problem of one-time positioning processing of irregularly rotating parts on the lathe, which makes the parts have high processing precision, stable product quality and improved processing efficiency.

Among the figure: 1 is a mandrel, 2 is a compression nut, 3 is a washer, 4 is a pressing plate, 5 is a bolt, and 6 is a part.

detailed description

The technical solution will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the described device comprises a mandrel 1, a compression nut 2, a washer 3, a pressing plate 4 and a bolt 5, the circumferential surface of the mandrel 1 is threaded, and the inner circumference of one end of the compression nut 2 is There is a boss on the surface, and a washer 3 is installed on the boss; the compression nut 2 is installed on the mandrel 1 through threaded connection; the end face of the mandrel 1 has a screw hole, and the bolt 5 is installed in the screw hole, and the pressure plate 4 Set on bolt 5.

As shown in FIG. 2 , only the mandrel 1 , the compression nut 2 and the washer 3 are required for machining the inner hole. Part 6 is set on the mandrel 1, and the compression nut 2 is set on the mandrel 1 through threaded connection. A boss is provided on the inner peripheral surface of one end of the compression nut 2. After the compression nut is tightened, the boss passes through the washer 3 Compressed on the boss on the outer peripheral surface of the part 6. The tooling is positioned with the inner hole of the part through the mandrel 1, and positioned with the outer peripheral surface of the part through the compression nut 2, finally ensuring the positioning accuracy of the part.

At the same time, as shown in FIG. 3 , when the inner hole needs to be processed and the outer peripheral surface needs to be processed, only the compression nut 2 needs to be removed, and the part itself does not need to be removed from the mandrel 1 . At this time, it is only necessary to press the pressure plate 4 on the mandrel 1 and the step of the inner hole of the part through the bolt 5 . While achieving double positioning, the device avoids secondary clamping and positioning when processing different parts, avoids the accumulation of positioning errors, improves the processing accuracy of the entire part, and improves the processing efficiency.
