Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

The first embodiment is as follows:

a positioning device for a cutting jig, as shown in fig. 1 and 2, comprising: base 100, ball 200, locating piece 300 and knob 400, base 100 is used for being fixed in the operation platform of cutting machine on, and ball 200 includes: the cutting jig comprises a screw 201 and a nut 202, wherein the screw 201 is installed on the base 100 and can rotate, the knob 400 is fixed at one end of the screw 201, and the positioning block 300 is fixed on the nut 202 and used for installing the cutting jig.

When in use, the position of the cutting jig can be moved by rotating the knob 400, and the operation is convenient; the ball screw 200 can realize continuous movement and has high position precision; the machine adjusting efficiency of the cutting machine is improved.

In this embodiment, it is necessary to ensure that the screw 201 has a certain degree of rigidity.

In order to prevent the positioning block 300 from bending the screw 201, a linear guide 500 is further provided, a guide 501 of the linear guide 500 is fixed on the base 100, and a slider 502 of the linear guide 500 is fixedly connected with the positioning block 300. The positioning block 300 is pressed on the base 100 through the linear guide 500, so that the damage to the screw 201 is avoided.

Example two:

this embodiment is a further improvement of the first embodiment, and as shown in fig. 3 and 4, a locking assembly 600 is added for fixing the position of the positioning block 300. After being adjusted to a preset position, the locking assembly 600 is locked, and then the cutting jig is fixedly connected with the operation table. The rest of this embodiment is the same as the first embodiment, and is not described again.

Specifically, as shown in fig. 3 and 4, the locking assembly 600 includes: two are flat-plate-shaped baffle plates 601, two baffle plates 601 parallel arrangement are fixed in respectively on locating piece 300, are provided with two-way cylinder 602 between two baffle plates 601, and two-way cylinder 602 is the product of selling, includes: a body 602a fixed on the base 100 and a piston rod 602b located at both sides of the body 602a, the piston rod 602b is perpendicular to the baffle 601, and the end of the piston rod 602b is used to be set on the baffle 601. When the positioning block 300 moves to a predetermined position, the bidirectional cylinder 602 is activated, the piston rod 602b extends to abut against the baffle 601, and a friction force is generated between the piston rod and the baffle 601 to limit the position of the positioning block 300.
