Description

A wire cutting grooving tooling

Technical field:

The utility model relates to a tool for cutting grooves by wire cutting.

Background technique:

In the process of mechanical processing, it is often encountered that the hardened workpiece is subjected to inclined groove cutting. The method of planing and milling increases with the increase in the hardness of the workpiece, and the requirements for the tool are higher, and the efficiency of the grinding method is very low. These methods The cutting heat is large, the workpiece is prone to local stress concentration, and the processing cost is high.

Utility model content:

The technical problem to be solved by the utility model is to provide a wire cutting and grooving tool that is easy to install, the positioning surface is the same as the design reference surface, the clamping precision is high, and the stress concentration is not easy to be generated during the processing. There is no limit to the hardness of the workpiece, and the processing cost is low.

The technical solution of the present invention is to provide a wire cutting tool for cutting grooves, which includes an angle adjustment device, a fixed table and a positioning piece. The rotating shaft is rotatably connected to the fixed plate, and the lower surface of the movable plate is provided with a support column on the side away from the rotating shaft. The support column is arranged horizontally and the top of its circumferential surface is fixed to the movable plate. The side surface of the fixed table close to the movable plate is concavely provided with a thread letting groove, and the fixed table is provided with a positioning piece for locating the workpiece to be processed.

After adopting the above structure, compared with the prior art, the utility model has the following advantages: use pads to raise the support column to a suitable height, then place a plane of the workpiece to be processed on the fixed table, and use the positioning piece for positioning, Then the utility model is placed on the workbench of the wire cutting machine tool, thereby processing the workpiece.

Preferably, the positioning member is one or more of positioning columns, positioning pins and positioning blocks. The positioning members are arranged on the fixed table according to the size of the workpiece to be processed, and the number of positioning members is not less than two.

Preferably, the locating member is a locating post or a locating pin, and the locating post or locating pin is fixed on the fixed platform by interference fit, screw connection or glue.

Further, it also includes a pressing block, which is directly pressed on the workpiece to be processed or pressed on the workpiece to be processed by bolts.

Fig. 2 is the use state diagram of the utility model.

Fig. 3 is a schematic structural view of the fixed platform of the present invention.

Detailed ways:

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

As shown in Figure 1-3, a wire cutting grooving tool includes an angle adjustment device, a fixed table 1 and a positioning piece 2, the angle adjustment device includes a fixed plate 3, and a movable plate 4 is horizontally arranged on the fixed plate 3, and the movable plate One side of the 4 is rotationally connected with the fixed plate 3 through the rotating shaft 6, and the rotating shaft is set on the lug on one side of the fixed plate, and at the same time is set on the connecting plate extending from the lower part of the movable plate side, and the lower surface of the movable plate 4 is far away from One side of the rotating shaft is provided with a support column 5, the support column 5 is horizontally arranged and its circumferential surface top is fixed with the movable plate 4, the support column 5 is arranged along the width direction of the movable plate, and the fixed table 1 can be fixed on the movable plate 4 by bolts, also It can be connected and fixed with clamps and clamping columns. The upper surface of the fixed table 1 is flat, and the side of the fixed table close to the side of the movable plate is concavely provided with a groove 11, and the fixed table 4 is provided with positioning for the positioning of the workpiece to be processed. Part 2, there are generally more than two positioning parts 2. Specifically, the locating piece is a combination of one or more of locating columns, locating pins and locating blocks, and the locating piece is set on the fixed table according to the size of the workpiece to be processed, such as two locating columns or two locating pins , It can also be the cooperation of a positioning column and 2 positioning pins, etc. In this embodiment, the positioning member 2 is a positioning column or a positioning pin, and the positioning column or positioning pin is fixed on the fixed table through interference fit, screw connection or glue, so as to position the workpiece 7 to be processed. In order to adapt to light-weight workpieces or workpieces with rough surfaces, it is difficult to completely position them solely by the above-mentioned positioning parts. At this time, external force is required for reinforcement, such as including a pressing block, which is directly pressed on the workpiece to be processed or pressed by bolts. Press on the workpiece to be processed, that is to say, the workpiece can be pressed by the weight of the briquetting block alone, or the workpiece can be fixed on the body with a bolted briquetting block. Since the workpiece to be processed is often arc-shaped, the positioning member can be provided with a positioning member according to the size of its center distance, and the positioning member is pressed against the outer surface of the workpiece to be processed for collision. In order to adjust the specific angle, the spacer 8 can be used in conjunction with different heights of the spacer to adapt to the angle required by different tooling.

When in use, one plane of the workpiece to be processed is placed on the fixed table plane of the tooling, and the other or two planes or curved surfaces are positioned by two or more positioning columns, and the tooling is adjusted by adjusting the height of the pad of the angle adjustment device. To the required angle, the angle adjustment device is connected with the tooling and placed on the workbench of the wire cutting machine tool, which can process grooves inclined to the plane on the workpiece.

The above is only a description of the preferred embodiments of the present utility model, but should not be construed as a limitation on the claims. Any equivalent structure or equivalent process transformation made by using the description and drawings of the utility model is included in the patent protection scope of the utility model.
