Description

A fixture for machine tool parts

technical field

The utility model relates to the field of fixtures for machinery, in particular to a fixture for machine tool sleeve parts.

Background technique

A machine tool fixture is a device on a machine tool for clamping a workpiece (and guiding a tool). Its function is to position the workpiece so that the workpiece can obtain the correct position relative to the machine tool and the tool, and clamp the workpiece reliably. The functions of machining work are: (1) to ensure the machining accuracy; (2) to increase productivity and reduce costs; (3) to expand the range of machine tools; (4) to reduce the labor intensity of workers.

At present, when planing, milling, and grinding machines process cylindrical workpieces, most of them use a slender slot on the fixture, place the cylinder wall at the chuck, and then tighten and fix it with screws. This internal clamping method has the disadvantages of cutting Falling into the slender groove, poor chip removal and other defects.

Utility model content

The technical problem to be solved by the utility model is to provide a fixture for machine tool sleeve parts with simple structure, the fixture can be easily adjusted according to the thickness of the sleeve, and the clamping is convenient and fast.

The utility model is realized through the following technical solutions: a fixture for machine tool sleeve parts, including an inverted T-shaped fixed clamp seat installed on the machine tool, and chucks sleeved at the steps on both sides of the fixed clamp seat , and the long-axis bolts that pass through the fixed clip seat to fix the chucks on both sides to the fixed clip seat laterally, and the two ends of the long-axis bolt are installed with nuts for fastening, and the lateral position near the step of the fixed clip seat is A threaded hole is provided, and a short-axis bolt is installed in the threaded hole. The outer end of the short-axis bolt is provided with a hemispherical plug, and the corresponding part inside the lower end of the chuck is provided with a hemispherical plug that matches the hemispherical plug. groove.

As a preferred technical solution, the length of the threaded hole is shorter than the length of the short-axis bolt, and the short-axis bolt and the threaded hole are fitted with coarse threads.

As a preferred technical solution, the long-axis bolt is specifically passed through the middle part of the chuck.

As a preferred technical solution, the nuts are fastened with double nuts.

As a preferred technical solution, the upper end of the chuck is configured as a curved pyramid head, and the inner surface of the pyramid head is provided with convex rubber for increasing friction.

The beneficial effects of the utility model for the fixture for machine tool sleeve parts are: it improves the shortcomings of the existing external clamp fixture such as cumbersome disassembly and inconvenient adjustment, simplifies the operation steps, improves the processing and work efficiency, and has a simple structure, and the fixture can be conveniently adjusted according to the set. The barrel thickness is adjusted, the clamping is convenient, fast and stable, and the work efficiency is improved.

Description of drawings

For ease of description, the utility model is described in detail by the following specific embodiments and accompanying drawings.

Fig. 1 is a structural schematic diagram of a fixture for machine tool sleeve parts of the present invention.

1. Fixed clip seat; 2. Chuck; 3. Long axis bolt; 4. Nut; 5. Threaded hole; 6. Short axis bolt; 7. Hemispherical head; 8. Pyramid head;

Detailed ways

As shown in Fig. 1, a kind of fixture for machine tool cover type parts, comprises and is installed on the machine tool and is the fixed fixture seat 1 of inverted T shape, and the collet 2 that is sheathed at the steps on both sides of the fixed fixture seat 1, and through The fixed clip seat 1 fixes the collets 2 on both sides laterally to the long-axis bolt 3 of the fixed clip seat 1, and the two ends of the long-axis bolt 3 are installed with nuts 4 for fastening. A threaded hole 5 is opened horizontally on the step part, and a short-axis bolt 6 is installed in the threaded hole 5. A hemispherical plug 7 is arranged on the outer end of the short-axis bolt 6, and a corresponding The position is provided with a hemispherical groove that cooperates with the hemispherical top 7 to play a positioning role.

Wherein, the length of the threaded hole 5 is shorter than the length of the short-axis bolt 6 , and the short-axis bolt 6 and the threaded hole 5 are fitted with coarse threads.

The long-axis bolt 3 is specifically pierced through the middle part of the chuck 2 .

The nut 4 is fastened with double nuts to improve fastness.

The upper end of the chuck 2 is set as a curved pyramid head 8, and the inner surface of the pyramid head 8 is provided with a bump rubber 9 for increasing friction.

Its basic working steps are as follows:

First of all, install the fixed clamp seat on the machine tool table, place the cylindrical workpiece to be clamped on the port of the clamping part, adjust the long-axis bolt according to the wall thickness of the processed cylinder, and tighten the two long-axis bolts at the same time. The nut at the end can be clamped to start the processing operation; another way is to adjust the length of the short axis bolt to adjust the size of the clamping force. question.

The beneficial effects of the utility model for the fixture for machine tool sleeve parts are: it improves the shortcomings of the existing external clamp fixture such as cumbersome disassembly and inconvenient adjustment, simplifies the operation steps, improves the processing and work efficiency, and has a simple structure, and the fixture can be conveniently adjusted according to the set. The barrel thickness is adjusted, the clamping is convenient, fast and stable, and the work efficiency is improved.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
