Description

A fixed-point rotating T-shaped fixture and locking block

technical field

The invention relates to the technical field of mechanical processing accessories, in particular to a T-shaped fixture placed in a T-shaped chute for clamping workpieces on a machine tool workbench and a lock block matched with it.

Background technique

In the prior art, placing the T-shaped fixture into the T-shaped chute usually requires the T-shaped fixture to enter the T-shaped chute from the initial part of the workbench, and when the T-shaped fixture slides to the designated position of the T-shaped chute , fasten the T-shaped fixture with bolts. However, this T-shaped jig needs to enter the T-shaped chute from the initial part of the workbench, and then slide to the designated position of the T-shaped chute, which reduces work efficiency. When iron filings are piled up in the T-shaped chute, it is not only difficult to replace the T-shaped fixture, but also hinders the normal sliding of the T-shaped fixture in the T-shaped groove, further reducing work efficiency.

Preferably, the orthographic projection of the flat head is a rectangle, and the length of the diagonal of the rectangle is ≤ the width of the bottom end of the T-shaped chute.

Preferably, the two sides of the long end of the orthographic projection of the flat head are arc-shaped, and the diameter of the arc is ≤ the width of the bottom end of the T-shaped chute.

The lock block provided by the present invention includes a body, and the body has two directions of X and Y. When the lock block is matched with the T-shaped clip and the T-shaped chute provided by the present invention, the upper edge of the lock block The direction of the length direction of the T-shaped chute is the X direction, and the direction perpendicular to the X direction on the lock block is the Y direction, and the length of the Y direction is equal to the distance between the tops of the T-shaped chute; The body includes a head and two legs, the two legs are respectively fixedly connected to both sides of the head along the X direction, the head is provided with a through hole, and the gap between the two legs is An accommodating space is provided, and the accommodating space communicates with the through hole. When the T-shaped fixture provided by the present invention is placed in the T-shaped chute and the long end of the flat head is connected to the T-shaped When the length direction of the chute is vertical, the lock block can cooperate with the T-shaped fixture provided by the present invention to fill the T-shaped chute. At this time, the lock block rides on the flat head, and the The screw rod passes through the through hole, and the two legs respectively hang on the two sides of the short end.

Preferably, the head and the two legs are integrally formed.

Preferably, the lock block further includes two shoulders, and the two shoulders are respectively fixedly connected to both sides of the head of the body along the Y direction.

Preferably, the two shoulders are integrally formed with the body.

When the fixed-point rotating T-shaped jig provided by the present invention is used, the long end is parallel to the length direction of the T-shaped chute. Since the size of the short end is smaller than the width of the top of the T-shaped chute, the T-shaped chute can be placed at the specified position. Put it directly into the bottom of the T-shaped chute. At this time, let the flat head rotate on the bottom of the T-shaped chute with the screw as the axis, so that the long end of the flat head is perpendicular to the length direction of the T-shaped chute. Therefore, the T-shaped fixture does not need to enter the T-shaped chute from the initial part of the workbench, and then slide to the designated position of the T-shaped chute, but can be directly inserted into the designated position of the T-shaped chute, which improves the work efficiency. Efficiency, even when the T-shaped chute is full of iron filings, it will not affect the assembly of the T-shaped fixture and the T-shaped chute. Utilize the through hole provided by the head of the lock block provided by the present invention and the accommodating space between the two legs of the lock block to make the lock block cooperate with the T-shaped clamp to fill the T-shaped chute, and the T-shaped clamp can be realized. with self-locking in that designated position. When using the T-shaped fixture, the T-shaped fixture can be disassembled by the reverse process of assembling the T-shaped fixture and the lock block to the T-shaped chute, so as to replace the T-shaped fixture.
