The lower ends of the positioning components are lifted and lowered to fix the product on the positioning platform.

[0007] As a further optimization scheme of the utility model, the positioning assembly includes a guide seat slidably set on the positioning rod and a screw rod with a vertical thread passing through the middle of the guide seat, a second knob is set at the upper end of the screw rod, and a clamping assembly is set at the lower end of the screw rod.

[0008] As a further optimization scheme of the utility model, the clamping assembly includes a connecting plate arranged at the lower end of the screw rod and a pressure plate vertically slidably arranged on the lower side of the connecting plate, a plurality of springs are arranged between the pressure plate and the connecting plate, and a sliding rod sliding through the connecting plate is fixedly arranged on the upper side of the pressure plate.

[0009] As a further optimization solution of the utility model, a guide groove with a cross-shaped cross section is horizontally opened on the inner side of the positioning rod, and the guide seat is a cross-shaped structure and slides in the guide groove.

[0011] As a further optimization solution of the present invention, the locking assembly includes a positioning screw that slides through the positioning platform and is threadedly connected to the slide seat, and a first knob that is fixedly arranged at one end of the positioning screw.

[0012] The beneficial effect of the utility model is that: in the utility model, the slide seat is made to slide on the slide groove, driving the positioning rod on the upper side of the slide seat to slide on the upper side of the positioning platform, so that the positioning component on the positioning rod fixes the metal product on the upper side of the positioning platform, and the positioning component can slide on the positioning rod, so that the positioning tooling can be flexibly adjusted according to the shape and size of the product, and the product is pressed down to position, and multiple positioning components are arranged on the guide rod, which can fix different positions of the product according to the shape of the product, thereby preventing the product from being locally deformed during laser welding, affecting the subsequent welding quality.

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example

[0019] like Figure 1 As shown, a positioning tool for a metal processing laser welding machine includes a positioning platform 1, a laser welding machine (not shown in the figure) is arranged above the positioning platform 1, two positioning rods 4 are relatively slidably arranged on the upper side of the positioning platform 1, a guide groove 6 with a "cross" cross section is horizontally opened on the inner side of the positioning rod 4, and a number of positioning components 5 are slidably arranged in the guide groove 6. This embodiment only shows two positioning components 5, and the specific number of positioning components 5 can be determined according to the size and number of products. The lower end of the positioning component 5 is lifted and lowered to fix the product on the positioning platform 1. When in use, it is only necessary to place the product to be welded on the positioning platform 1, and then slide the two positioning rods 4, and then slide the two positioning components 5 on the positioning rod 4, so that the positioning component 5 is located above the product to be positioned, and the positioning component 5 is used to position the product.

[0020] like Figure 1 , Figure 2 As shown, the positioning assembly 5 includes a guide seat 501 slidably arranged on the positioning rod 4 and a screw rod 503 with a vertical thread penetrating the middle of the guide seat 501, a second knob 502 is arranged at the upper end of the screw rod 503, a connecting plate 507 arranged at the lower end of the screw rod 503, and a pressing plate 504 slidably arranged at the lower side of the connecting plate 507, a plurality of springs 506 are arranged between the pressing plate 504 and the connecting plate 507, and a sliding rod 505 slidably penetrating the connecting plate 507 is fixedly arranged on the upper side of the pressing plate 504. When in use, the screw rod 503 can be driven to rotate by rotating the second knob 502, so that the screw rod 503 moves vertically downward on the guide seat 501, driving the connecting plate 507 and the pressing plate 504 to descend together, so that the product on the upper side of the positioning platform 1 can be quickly positioned, and through the spring 506, when the pressing plate 504 presses the product, the pressing force can be slowly increased to prevent the product from being crushed.

[0021] like Figure 1 , Figure 3 As shown, slide grooves 2 are provided on both sides of the positioning platform 1, and slide seats 3 slidably connected to the slide grooves 2 are fixedly provided at both ends of the positioning rod 4.

[0022] It should be noted that, when using the positioning fixture of the metal processing laser welding machine, the product to be welded is first placed on the positioning platform 1, and then the two positioning rods 4 are slid so that the slide seats 3 at both ends of the two positioning rods 4 slide on the inner side of the slide groove 2. When the two positioning rods 4 are moved to the top of the product to be welded, the first knob 8 is rotated to drive the positioning screw 7 to engage with the thread of the slide seat 3. Since one side of the first knob 8 is against the side of the positioning platform 1, the slide seat 3 can be fixed on the positioning platform 1 at a certain position, and then the guide seat 501 on the two positioning rods 4 is slid. When the guide seat 50 When the positioning platform 1 moves to the top of the product, the second knob 502 is rotated to drive the screw rod 503 to rotate, so that the screw rod 503 moves downward vertically on the guide seat 501, driving the connecting plate 507 and the pressing plate 504 to descend together, so that the product on the upper side of the positioning platform 1 can be quickly positioned, and through the spring 506, when the pressing plate 504 presses the product, the pressing force can be slowly increased to prevent the product from being crushed, and finally the product can be positioned. The positioning tooling of this solution can be flexibly adjusted according to the shape and size of the product, so that products of different shapes and sizes can be positioned, expanding the application range of welding.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
