Specific embodiments

[0023] Hereinafter, in combination with the accompanying drawings and specific embodiments, the technical solutions of the present utility model will be further described in detail.

[0024] As Figures 1-6 shown, the laser cutting workpiece positioning device for sheet metal processing provided in this embodiment includes a base 1. A placement groove for placing a drive motor 2 is opened in the base 1. A drive motor 2 is arranged in the placement groove of the base 1. Heat dissipation holes 23 communicating with the placement groove are opened on the base 1 to achieve the heat dissipation effect of the drive motor 2. The output end of the drive motor 2 is connected to a first base 3. The drive motor 2 can be used to drive the first base 3 to rotate and adjust. The upper end surface of the first base 3 is slidably provided with a drive base 4 through an electric slide rail 7.

[0025] Furthermore, the drive base 4 includes a sliding base 8 connected to the electric slide rail 7, a sliding groove 9 opened inside the sliding base 8, a lead screw 10 rotatably connected inside the sliding groove 9, and a first drive motor 11 for driving the lead screw 10.

[0026] Furthermore, the sliding base 8 and the electric slide rail 7 are in a cross shape, ensuring that the second base 5 can perform synchronous sliding or independent sliding adjustment in the horizontal and vertical directions, further improving the flexibility of the device during use. The first drive motor 11 is fixedly arranged outside one end of the sliding base 8 through a fixed rod.

[0027] Furthermore, a sliding block 12 which is slidably connected to the inside of the sliding groove 9 and threadedly connected to the lead screw 10 is provided on the lower end surface of the second base 5. Two mutually staggered and cross-shaped sliding grooves 13 are formed on the upper end surface of the second base 5. When it is necessary to adjust the position of the second base 5 clamping the sheet metal part, the electric slide rail 7 is used to drive the driving base 4 and the second base 5 to slide longitudinally. At the same time, the first driving motor 11 is used to drive the lead screw 10 to rotate, driving the sliding block 12 to slide in the sliding groove 9, realizing the lateral sliding adjustment of the second base 5 clamping the sheet metal part, so as to improve the flexibility of the positioning device during use.

[0028] Furthermore, an annular groove 24 is formed on the upper end surface of the base 1. An annular ring 25 which is slidably connected to the annular groove 24 is provided on the lower end surface of the first base 3. A plurality of steel balls 26 are rotatably connected to the lower end surface of the annular ring 25. The arrangement of the annular groove 24 and the annular ring 25 can improve the support for the rotation of the first base 3, and the plurality of steel balls 26 rotatably provided on the lower end surface can realize the flexibility of the annular ring 25 during rotation.

[0029] The second base 5 is slidably connected to the driving base 4, and a sheet metal part clamping mechanism 6 is provided on the upper end surface of the second base 5.

[0030] Furthermore, the sheet metal part clamping mechanism 6 includes a first bidirectional lead screw 15 and a second bidirectional lead screw 16 which are respectively rotatably connected to the inside of the two sliding grooves 13, a second driving motor 17 and a third driving motor 18 for driving the first bidirectional lead screw 15 and the second bidirectional lead screw 16, and clamping plates 19 slidably arranged at both ends of the sliding grooves 13.

[0031] Even further, the second driving motor 17 and the third driving motor 18 are both fixed to the outside of the second base 5 through fixing rods. The first bidirectional lead screw 15 and the second bidirectional lead screw 16 are arranged in a mutually staggered manner, so that the first bidirectional lead screw 15 and the second bidirectional lead screw 16 do not affect each other during rotation. A sliding block 20 which is slidably connected to the sliding groove 13 is provided on the lower end surface of the clamping plate 19. A plurality of sliding blocks 20 are respectively threadedly connected to the first bidirectional lead screw 15 and the second bidirectional lead screw 16. When clamping and fixing the sheet metal part, the second driving motor 17 and the third driving motor 18 are used to drive the first bidirectional lead screw 15 and the second bidirectional lead screw 16 to rotate, adjusting the positions of the plurality of clamping plates 19. After the adjustment is completed, the sheet metal part is placed on the surface of the second base 5, and then the second driving motor 17 and the third driving motor 18 are used to drive the first bidirectional lead screw 15 and the second bidirectional lead screw 16 to rotate, driving the plurality of clamping plates 19 to approach and clamp the sheet metal part, realizing the clamping and fixing of the sheet metal part.

[0032] Furthermore, a second electric slide rail 21 is vertically arranged inside a group of opposite clamping plates 19. A pressing plate 22 is slidably connected through the second electric slide rail 21. By driving the pressing plate 22 to slide downward by the second electric slide rail 21, the fixing effect on the clamped sheet metal parts can be further improved.
