The pressure maintaining block 210 is formed with a receiving groove 220 for placing a product to be processed, a receiving block 221 is arranged in the receiving groove 220, a limiting protrusion 222 for placing the product is also arranged in the receiving groove 220, and the limiting protrusions 222 are symmetrically arranged in the receiving groove 220. When the product is placed in the receiving groove 220, the side wall of the limit protrusion 222 contacts the outer wall of the product, thereby fixing the product.

As shown in fig. 1 to 4, an elastic module is disposed in the pressure maintaining block 210 along the Z-axis direction, and the elastic module is used for elastic pressure maintaining of the product. The elastic module comprises a first stop 310 contacting with the product, a plurality of second stop 330 penetrating through the pressure maintaining block 210 and connected with the accommodating block 221, and a plurality of first elastic members 320, wherein the first elastic members 320 are preferably springs. The spring has good elastic deformability and is low in cost. The number of second stoppers 330 is four and the arrays are distributed in the pressure-maintaining block 210. One end of the second stop block 330 penetrates through the pressure maintaining block 210 and is connected with the accommodating block 221, a stud is arranged at one end of the second stop block 330 connected with the accommodating block 221, and a screw groove matched with the stud is formed in the accommodating block 221. The first stopper 310 and the second stopper 330 are embedded in the pressure-maintaining block 210, and the first stopper 310 is located on the bottom surface of the receiving groove 220. When the product is placed in the limiting boss 222 and the jig main body is reversely buckled on the tool, the first stop block 310 abuts against the product on the tool through gravity, and similarly, the second stop block 330 abuts against the accommodating block 221 on the tool. One end of the first elastic member 320 is connected to the first stopper 310 or the second stopper 330, and the other end of the first elastic member 320 is disposed in the base block 100. The first stopper 310 includes a stopper rod 311 embedded in the pressure-maintaining block 210 and the base block 100, and a spring block 312 fixed to one end of the stopper rod 311. The spring 312 is in contact with the product. The spring 312 is made of a flexible material, such as rubber, to prevent the spring 312 from contacting the product and scratching the product.

As shown in fig. 1 and 5, a clamping block 400 capable of sliding along the Y-axis direction is inserted into the pressure maintaining block 210, and the other end of the clamping block 400 extends into the accommodating groove 220 and abuts against the product. The clamping block 400 is in a hook shape, one end of the clamping block 400 extends out of the pressure maintaining block 210, and the other end of the clamping block 400 extends into the accommodating groove 220 and abuts against the product. A worker may manually press a portion of the cartridge 400 extending out of the pressure maintaining block 210 such that the cartridge 400 can slide along the Y axis; the cartridge 400 may be also be assembled into an automatic pressing device by an air pump or other structures to press the cartridge in the Y-axis direction. The side of the cartridge 400 is provided with a second elastic member 410 elastically deformed in the Y-axis direction. The second elastic member 410 is a spring. The other end of the second elastic member 410 abuts against the inner wall of the pressure maintaining block 210. The cartridge 400 compresses the second elastic member 410 during the movement along the Y-axis, and at this time, the product is placed in the receiving groove 220. Thereafter, the force applied to the cartridge 400 is removed, so that the cartridge 400 moves in the opposite direction of the Y-axis by the second elastic member 410 until the other end of the cartridge 400 abuts against the outer wall of the product and the product is fixed in the receiving groove 220.

As shown in fig. 1 and 6, jaw assemblies 500 and grooves 600 for accommodating the jaw assemblies 500 are provided on both sides of the pressure maintaining block 210 in the X-axis direction, and the grooves 600 are provided in the Z-axis direction. The clamping jaw assembly 500 is used for fixing the whole jig body on a tool along the Z-axis direction. The pressure block 210 is internally penetrated with a connecting piece, and both ends of the connecting piece are connected with the grapple 510. Wherein preferably the connection member is a wire rope. The jaw assembly 500 includes a grapple 510 positioned within a recess 600. A rotation shaft 520 is provided in the groove 600 in the Y-axis direction and the rotation shaft 520 passes through the grapple 510, and the grapple 510 rotates about the rotation shaft 520. The grapple 510 is provided on a side thereof with a third elastic member 530, and the third elastic member 530 is located above the rotation shaft 520 and is disposed in the X-axis direction. The third elastic member 530 is preferably a spring. The third elastic member 530 applies a force in the X-axis direction to the grapple 510 so that the grapple 510 can rotate. A stopper 540 for restricting rotation of the grapple 510 is provided on an end surface of the pressure maintaining block 210. The stopper 540 is in a long bar shape and is fixed to the bottom surface of the pressure-maintaining block 210 by bolts. The working end of the grapple 510 will abut against the stopper 540. When the grapple 510 is operated, the third elastic members 530 located at both sides apply a force to the grapple 510 so that the grapple 510 can be rotated. However, at the same time, one end of the grapple 510 is limited by the connector and the other end is limited by the stopper 540, so that the grapple 510 can be maintained in a vertical state in the Z-axis direction.

Working principle: the cartridge 400 is pressed by a manual or automatic means. The product is then placed into the receiving groove 220 and the pressing of the cartridge 400 is released. Thus, the fixture block 400 primarily fixes the product. The jig body is reversely buckled on the workbench and is preliminarily fixed through the positioning rod 110. The worker applies a force to the grapple 510 such that the working end of the grapple 510 is embedded in the tool, and then the worker removes the force. Under the action of the connecting member, the third elastic member 530 and the limiting block 540, the grapple 510 is fixed, so as to fix the whole fixture body.

Under the action of gravity, the first stop 310 moves downward, and the first stop 310 drives the first elastic member 320 to stretch. The second block 330 and the accommodating block 221 in the pressure maintaining block 210 will move downward, and the second block 330 and the accommodating block 221 will drive the first elastic member 320 to stretch out and draw back. When the jig main body is buckled on the fixture, the product can apply a force on the first stop block 310, and the fixture can also apply a force on the accommodating block 221, so that a force is applied on the first elastic piece 320. The first stop block 310 is abutted against the product by the elastic deformation force of the first elastic piece 320, and the second stop block 330 is abutted against the tool, so that a better pressure maintaining effect is achieved.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and it should be noted that it is possible for those skilled in the art to make several improvements and modifications without departing from the technical principle of the present utility model, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
