DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Please refer to the attached Figure 1-6The utility model provides a positioning bracket for stamping automobile parts, comprising a stamping table 1 and a part body 2 to be stamped, a gantry 3 is fixed at both ends of the top of the stamping table 1, a base 4 is fixed at the center of the top of the stamping table 1, a stamping assembly is arranged on the gantry 3, and the part body 2 is detachably fixed to the top of the base 4 by a clamping positioning assembly;

[0026] The stamping assembly includes a transversely arranged X-axis electric linear slide 5. It should be noted that the electric linear slide is a device that realizes linear motion by being driven by a motor. The top of the X-axis electric linear slide 5 is fixed to the lower surface of the top of the gantry 3. The output end of the X-axis electric linear slide 5 is fixed with a first connecting plate 6. The bottom of the first connecting plate 6 is longitudinally fixed with a Y-axis electric linear slide 7. The output end of the Y-axis electric linear slide 7 is fixed with a second connecting plate 8. The bottom of the second connecting plate 8 is fixed with a mounting frame 9. The mounting frame 9 is U-shaped, that is, when the X-axis electric linear slide 5 is running, it can drive the mounting frame 9 to move transversely and longitudinally. When the Y-axis electric linear slide 7 is running, it can drive the mounting frame 9 to move linearly and reciprocatingly in the longitudinal direction. A hydraulic cylinder 10 is vertically fixed to the bottom of the inner wall of the mounting frame 9. The bottom end of the output shaft of the hydraulic cylinder 10 vertically passes through the bottom of the mounting frame 9, and a punch head 11 is fixed to the bottom end of the output shaft of the hydraulic cylinder 10. Specifically, when the hydraulic cylinder 10 is running, it can drive the punch head 11 to do feeding movement, and the punch head 11 can be controlled by the X-axis electric linear slide 5 and the Y-axis electric linear slide 7 to move linearly and reciprocatingly in the horizontal direction and linearly and reciprocatingly in the longitudinal direction, so that the part body 2 can be punched at different positions.

[0027] The clamping and positioning assembly includes an open groove 12, which is opened at the center of the top of the base 4. A partition 13 is horizontally fixed above the inside of the open groove 12. A limiting hole 14 is vertically opened in the center of the partition 13. A pressure rod 15 vertically penetrates the limiting hole 14, and the hole wall of the limiting hole 14 fits with the surface of the pressure rod 15. A ball head 16 is fixed on the top of the pressure rod 15, that is, when the staff places the part body 2 to be stamped on the base 4, the part body 2 can press down the ball head 16 under the action of its own weight, and a guide block 17 is fixed to the bottom end of the pressure rod 15, that is, when the part body 2 presses down the ball head 16, it will drive the guide block 17 through the pressure rod 15. The guide block 17 moves downward in the opening groove 12, and a return spring 18 is fixed on the top of the guide block 17. The top of the return spring 18 is fixed to the bottom of the partition 13. Therefore, when the guide block 17 is forced to move downward, the return spring 18 can be stretched to make the return spring 18 elastically deformed to generate elastic force. Under the action of this elastic force, when the part body 2 is removed, that is, when the ball head 16 is no longer pressed down, the guide block 17 can automatically move up and return to its original position. The four side ends of the base 4 are provided with strip holes 19, and the strip holes 19 are penetrated by guide rods 20, and the wall of the strip hole 19 is in contact with the surface of the guide rod 20. The strip hole 19 is set as a rectangular hole, and the cross-section of the guide rod 20 is rectangular (such as Figure 5As shown), the guide rod 20 with a rectangular cross section cannot rotate with the strip hole 19 set as a rectangular hole, that is, the guide rod 20 can stably move in a straight line, and the ends of the four guide rods 20 extending into the open groove 12 are all set as inclined surfaces, and the end surfaces of the four guide rods 20 extending into the open groove 12 are respectively abutted against the four side ends of the guide block 17. Specifically, when the guide block 17 moves downward, the ends of the guide rods 20 set as the inclined surfaces can be squeezed downward to control the movement of the four guide rods 20;

[0028] A group of end plates 21 are also fixed to the four side ends of the base 4, and each group of end plates 21 has two end plates 21. An extrusion plate 22 is rotatably connected between the two end plates 21 of the same group. The end of the guide rod 20 away from the guide block 17 abuts against the bottom end of the extrusion plate 22, that is, when the guide rod 20 is squeezed and moved by the guide block 17 downward, it can push the bottom end of the extrusion plate 22. An extrusion block 23 is fixed to the top of the extrusion plate 22, and the extrusion block 23 is set to a cylindrical shape. The four ends of the top of the base 4 are slidably connected with a clamping plate 24 in a rectangular array. The end of the clamping plate 24 close to the part body 2 abuts against the four side ends of the part body 2 respectively. The clamping plate The end of 24 away from the part body 2 is respectively in contact with the surfaces of the four extrusion blocks 23. Specifically, when the guide rod 20 pushes the bottom end of the extrusion plate 22, according to the lever principle, the extrusion block 23 at the top of the extrusion plate 22 can apply an extrusion force to the clamping plate 24. Then, when the punch head 11 moves down to punch the part body 2, as the pressure on the part body 2 increases, the extrusion force applied by the extrusion block 23 to the clamping plate 24 increases, thereby effectively increasing the clamping force of the clamping plate 24 on the part body 2. That is, when the part body 2 is punched, the greater the pressure it is subjected to, the greater the clamping force it is subjected to, and the better the clamping effect;

[0029] An upper limit block 25 is fixed to the side of the inner wall of the opening groove 12, and a lower limit block 26 is fixed to the bottom of the inner wall of the opening groove 12. When the top of the guide block 17 fits with the lower surface of the upper limit block 25, the side end of the guide block 17 abuts against the upper inclined end of the inclined surface of the end of the guide rod 20. When the bottom of the guide block 17 fits with the upper surface of the lower limit block 26, the side end of the guide block 17 abuts against the lower inclined end of the inclined surface of the end of the guide rod 20. Specifically, under the joint limiting action of the upper limit block 25 and the lower limit block 26, the four side ends of the guide block 17 can be effectively prevented from being separated from the four inclined surfaces of the end of the guide rod 20, thereby ensuring the stability of the positioning bracket during use.

[0030] The use process of the utility model is as follows: the staff first places the part body 2 to be stamped between the four clamping plates 24 at the top of the base 4. The part body 2 can press the ball head 16 under the action of its own weight, thereby driving the guide block 17 to move downward. When the guide block 17 moves downward, the four guide rods 20 can be controlled to move by squeezing the end of the guide rod 20 set as an inclined surface downward, so as to push the bottom end of the extrusion plate 22. When the guide rod 20 pushes the bottom end of the extrusion plate 22, according to the lever principle, the extrusion block 23 at the top of the extrusion plate 22 can apply an extrusion force to the clamping plate 24, so as to preliminarily position and clamp the part body 2. Then, when the punch head 11 moves downward to punch the part body 2, as the pressure on the part body 2 increases, the extrusion force applied by the extrusion block 23 to the clamping plate 24 is greater, thereby effectively increasing the clamping force of the clamping plate 24 on the part body 2, that is, when the part body 2 is subjected to stamping, the greater the pressure it is subjected to, the greater the clamping force it is subjected to, and the better the clamping effect.

[0031] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
