The first notch and the second notch are identical in size and shape.

The inner walls of the first notch and the second notch are provided with protruding teeth.

Four corners of the bottom of the outer wall of the support are fixedly connected with the inner sides of the supporting legs respectively.

The utility model has the beneficial effects that: the utility model can realize the rapid centering and fixing of the round tube. The bull stick rotates at the inner wall of riser, and pivoted bull stick drives first gear and rotates to first gear drives the second gear and rotates, and the screw rod rotates and makes can drive the triangle and move downwards, and this can make the inner wall top of first notch gradually to work piece department remove, until the inner wall top of first notch supports tightly with the work piece top after, stops rotating the bull stick, accomplishes the centre gripping of work piece, and first notch and second notch cooperation can be realized fast and press from both sides the centering of pipe tightly fixedly.

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic diagram of the connection relationship between the riser, the rotating rod and the first gear in FIG. 1;

FIG. 3 is a schematic cross-sectional view of FIG. 2;

fig. 4 is a schematic structural diagram of the connection relationship between the first gear, the second gear and the screw in fig. 1.

In the figure: 1. the device comprises a bracket, 101, square plates, 2, a control mechanism, 201, a rotating rod, 202, a first gear, 203, a second gear, 204, a screw, 205, a triangular plate, 206, a first notch, 3, supporting legs, 4, vertical plates, 5, a second notch, 6 and a cylinder.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

please refer to fig. 1-4: the round tube to be clamped and fixed is inserted into the area surrounded by the second notch 5 and the first notch 206. After the rotating rod 201 is rotated, the first gear 202 rotates to drive the second gear 203 to rotate, the second gear 203 rotates to drive the screw 204 to rotate, and the screw 204 rotates to drive the triangular plate 205 to lift; the triangular plate 205 can be lifted to reduce the range of the first notch 206 and the second notch 5, the first notch 206 and the second notch 5 can be extruded to the outer wall of the circular tube by reducing the range, and then the clamping is realized, and the centering clamping can be realized because the first notch 206 and the second notch 5 are both triangular.

The inner walls of the first groove 206 and the second notch 5 are both machined with protruding teeth, which can increase friction with the workpiece.

When the centering fixture is used, the bottoms of the supporting legs 3 are contacted with the ground, the whole fixture is supported, a workpiece passes through the front second notch 5, then passes through the first notch 206, finally passes through the rear second notch 5, then the rotating rod 201 rotates, the rotating rod 201 drives the first gear 202 to rotate, the first gear 202 drives the second gear 203 to rotate, the rotating second gear 203 drives the screw 204 to rotate on the inner wall of the cylinder 6, the triangular plate 205 is driven to move downwards due to the limitation of the inner wall of the bracket 1 on the position of the triangular plate 205 by rotating the screw 204, the top of the inner wall of the first notch 206 gradually moves towards the workpiece until the top of the inner wall of the first notch 206 abuts against the top of the workpiece, the rotating rod 201 stops rotating, the clamping of the workpiece is completed, and the centering clamping and fixing of the round tube can be realized by matching the first notch 206 and the second notch 5.

The utility model can realize the rapid centering and fixing of the round tube.
