Description

General type turning frock

Technical Field

The invention belongs to the technical field of machine manufacturing, and particularly relates to a universal type turning tool for end face positioning and screw fixing.

Background

In the mechanical manufacturing process, particularly in the precise turning stage of weak rigid parts, the parts cannot be stressed radially, need to be positioned by an end face, and are pressed on a disc chuck by screws for clamping. Due to the fact that the parts are different in structure and size, one flower disc is required to be manufactured on one part, and therefore machining cost is greatly improved. The existing clamping tool cannot well solve the problem.

In order to reduce the production cost and improve the utilization rate of the tool, the invention provides the universal type turning tool which can adjust the hole pitch, the uniform distribution quantity of holes and the aperture size.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: at the accurate turning stage of weak rigidity part, remedy the not enough of current processing frock, provide a hole pitch is adjustable, the aperture is optional, the general type processing frock that hole equipartition quantity can set up, and can realize just with turning over two kinds of operating modes, convenient operation combines the processing current situation, reduction in production cost improves production efficiency.

In order to solve the technical problems, the invention is realized by the following scheme:

a universal turning tool comprises a sector block, a first screw, a graduated scale, a T-shaped block, a double-sided workbench, a transfer shaft and a second screw; the fan-shaped block is connected with the double-sided workbench through a first screw and a T-shaped block, threaded holes and unthreaded holes with different sizes are distributed on the fan-shaped block so as to adapt to the sizes of the mounting holes of the parts, and the holes on the fan-shaped block are also uniformly distributed because the fan-shaped block is uniformly distributed, and the fan-shaped block can adapt to the mounting holes with various sizes and can realize two clamping modes of a front handle and a reverse handle; the double-sided workbench is fixed on the transfer shaft through a second screw, is used for clamping other tool parts, and can adapt to 3, 4, 6, 8 and 12 uniformly distributed mounting holes; the adapter shaft is connected with a main shaft of the machine tool through a screw; the graduated scale is installed on a workbench of the machine tool through screws and used for displaying the radial position of the installation hole; the T-shaped block fixes the fan-shaped block in a T-shaped groove of the workbench through a first screw, and the fan-shaped block can adapt to the size of an inner hole of a part when moving along the T-shaped groove, so that the parts with different sizes are fixed.

Compared with the existing turning tool for faceplates, the turning tool has the advantages that:

1. the invention has simple structure and wide application range, both sides of the workbench can be used, one side is provided with 12T-shaped grooves which can be suitable for 3, 4, 6 and 12 uniformly distributed mounting holes, the other side is provided with 8T-shaped grooves which can be suitable for 4 and 8 uniformly distributed mounting holes, and the number of the mounting holes which are commonly used by parts is covered;

2. the fan-shaped block can slide along the T-shaped groove, so that the installation of parts with different hole pitches is adapted;

3. the fan-shaped block is of an I-shaped structure, and can realize a forward handle and a backward handle;

4. holes with various apertures are distributed on the fan-shaped block so as to adapt to the size of a part mounting hole;

5. compared with other disc chuck tools, the disc chuck tool has the advantages of wide application range and high repeated utilization rate, and greatly reduces the production cost.
