Abstract

The invention relates to a T-shaped adjustable clamp for a wire cutting machine tool, which relates to the field of clamps. The invention can be used for the clamping of workpieces processed on electric discharge wire cutting machine tools. The fixture includes a fixture block, a guide rail with a T-shaped slot, a compression bolt, a spacer, and a compression piece. Among them, a transverse T-shaped slot matching the shape of the lower part of the fixture block is machined on the guide rail, the fixture block is placed in the T-shaped slot, and the fixture block and the T-shaped slot slide relative to fix the workpiece from both sides. The compression piece is installed, and the compression bolt can rotate up and down relative to the two shoulders of the fixture block. Due to the different sizes of the workpieces, the positions of the two clamping blocks are adjusted by the tightness of the compression bolts. Therefore, the fixture can be clamped flexibly accordingly, does not affect the processing efficiency, and is easy to process.

Description

A T-shaped adjustable fixture for a wire cutting machine tool

technical field

The invention relates to a fixture on a wire electric discharge machine tool.

Background technique

At present, in the actual processing process, the thickness and specification of the workpiece are changeable and replaced frequently, which not only affects the clamping efficiency, but also increases the labor load of workers. The previous clamping method not only slows the loading speed but also takes a long time for calibration, which greatly reduces the processing efficiency.

Contents of the invention

The invention provides a T-shaped slot fixture for clamping workpieces on a wire electric discharge machine tool. In order to achieve the above purpose, a transverse T-shaped slot matching the shape of the lower part of the fixture block is processed on the guide rail, and the fixture block is placed on the In the T-shaped slot, the clamp block and the T-shaped slot slide relative to each other to fix the workpiece from both sides. A compression piece can be installed on the clamp block, and the compression bolt can rotate up and down relative to the two shoulders of the clamp block.

When the workpiece is placed in a certain processing position, the T-shaped blocks on both sides can be slid to clamp the workpiece from both sides. Then turn the compression bolt to move up and down relative to the T-shaped block to compress or loosen the T-shaped block, thereby realizing tightening or loosening the processed workpiece.

The advantage of the invention is that even if the thickness of the workpiece varies, the fixture can be flexibly clamped accordingly, without affecting the processing efficiency, and the fixture body is easy to process. The upper side of the fixture block can be installed with a compression piece according to the shape of the workpiece, and the upper and lower sides of the fixture block can be fitted with the upper and lower sides of the T-shaped slot, which can effectively prevent the shaking of the fixture block due to the positioning force of the workpiece, and can effectively ensure the accuracy.

Description of drawings

Fig. 1 is a schematic structural view of the present invention.

Detailed ways

In Fig. 1, 1, guide rail 2 with T-shaped groove, clamp block 3, clamp body 4, compression bolt 5, compression piece 6, spacer. The invention can be used for the clamping of workpieces processed on electric discharge wire cutting machine tools. The fixture includes a fixture block, a guide rail with a T-shaped slot, a compression bolt, a spacer, and a compression piece. The gasket is placed in the groove of the fixture block to prevent the compression bolt from destroying the precision of the guide rail with the T-shaped groove after long-term use. The tightening bolt can be placed on the gasket and rotated up and down, so that the fixture block can move back and forth. The upper side of the fixture block can be equipped with different shapes of pressing pieces according to the shape of the workpiece, and the surface of the fixture body perpendicular to the direction of the guide rail can also prevent the workpiece from tilting.

When in use, the distance between the clamp blocks can be adjusted according to the size of the workpiece to be processed. The workpiece is installed between the two clamp blocks, and the clamping bolt is adjusted to fix the clamp block, thereby limiting the movement of the workpiece. The surface of the clamp body perpendicular to the direction of the guide rail can also limit the relative movement of the workpiece. The upper side of the clamp block can be installed with a compression piece according to the shape of the workpiece. The upper and lower sides of the clamp block can be fitted with the upper and lower sides of the T-shaped slot, which can effectively prevent clamping The shaking caused by the positioning force of the workpiece can effectively ensure the accuracy.

Claims (3)

1. a kind of electric spark linear cutting machine T-slot fixture, the workpiece with flexible clamping different-thickness, feature include pressing from both sides Have block, the guide rail with T-slot, hold-down bolt, gasket, compress piece.

2. clamp block position can be adjusted with the difference of thickness of workpiece, in T-slot opposite sliding occurs for clamp block.
