Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting positioning tooling, and specifically relates to a laser cutting positioning bracket. Background Art

[0002] Stamping parts in the automotive trial production industry are usually not manufactured using trimming and punching dies, but are instead processed using laser cutting. Currently, laser cutting in the industry requires the workpiece to be placed on a fixed bracket for cutting to ensure the stability of the parts. Different parts may require different brackets, and the brackets for different parts need to be redesigned as a whole. After the design is completed, a series of processing processes such as plate cutting, assembly, and welding are required to remake the brackets, which increases design and production costs and consumes a lot of materials. Especially for trial production projects, the demand for parts is small, the reuse rate is low, and the cost is higher. After the brackets are used up, they are often piled up in the corner to take up space, resulting in serious waste of materials.

[0003] Therefore, a laser cutting positioning bracket is used to solve the above problems. Utility Model Content

The matching installation of the corresponding base plate mounting positions is achieved according to the different positions of the bottom supporting surfaces of different parts. The installation is simple and quick, the versatility is extremely high, and the part design cost is low. Only one set of laser cutting positioning brackets is required to meet the cutting and fixing requirements of different parts.

[0005] To achieve the above-mentioned purpose, the utility model provides a laser cutting positioning bracket, including a base plate and a positioning bracket assembly; the top of the base plate has a plurality of mounting positions, and the positioning bracket assemblies have multiple positions, and the top surface of each positioning bracket assembly has a contoured surface that matches the bottom supporting surface of the part to be cut, and each positioning bracket assembly is installed corresponding to the plurality of mounting positions of the base plate based on the position of the bottom supporting surface of the part to be cut.

[0006] Furthermore, the positioning bracket assembly includes a support plate, a positioning block, a fixing rod and a stabilizing bracket; the support plate is installed on the top of the positioning block, and the top surface of the support plate has a contoured surface that matches the bottom supporting surface of the part to be cut; one end of the fixing rod is installed on the positioning block, and the other end is installed in the mounting position of the base plate; the stabilizing bracket is installed on the fixing rod and the base plate respectively.

[0007] Furthermore, the upper end surface of the positioning block has a fixing groove, and the bottom of the support plate is installed in the fixing groove.

[0008] Furthermore, the side surface of the positioning block has at least one threaded hole, the threaded hole of the positioning block is communicated with the fixing groove of the positioning block, and a corresponding fastener is installed in the threaded hole of the positioning block and abuts against and locks with the support plate.

[0009] Furthermore, the stabilizing bracket includes a latch and a pressure plate, the lower end of the fixing rod has a latch hole, and the top surface of the base plate has a latch mounting groove and a pressure plate fixing hole; the latch passes through the latch hole of the fixing rod and is installed in the latch mounting groove on the top surface of the base plate, and there are two pressure plates, one end of each of the pressure plates is pressed on one end of the top surface of the latch, and the other end is pressed on the top surface of the base plate for fixation.

[0011] Furthermore, the fixing groove of the positioning block is a cross-shaped groove, and the supporting plate is a cross-shaped plate.

[0012] The beneficial effects of the utility model are:

[0013] First, the top of each positioning bracket assembly of the utility model is designed with different contour surfaces according to the bottom support surfaces of different parts, so that the positioning bracket assembly and the bottom plate can be installed in combination, and the matching installation of the corresponding bottom plate installation position can be achieved according to the different positions of the bottom support surfaces of different parts. The installation is simple and fast, the versatility is extremely high, and the part design cost is low. Only one set of laser cutting positioning brackets is needed to meet the cutting and fixing requirements of different parts;

[0033] Refer to the instruction manual Figure 3-5 This embodiment includes all the structures of embodiment 1, and the positioning bracket assembly 2 includes a support plate 20, a positioning block 21, a fixing rod 22 and a stabilizing bracket 23. The plurality of mounting positions on the top of the base plate 1 are mounting holes 10, and the plurality of mounting holes 10 are arranged in a matrix.

[0034] The support plate 20 is mounted on the top of the positioning block 21, and the top surface of the support plate 20 has a contoured surface that matches the bottom support surface of the part to be cut.

[0037] Example 3

[0038] Refer to the instruction manual Figure 6 On the basis of Embodiment 2, the upper end surface of the positioning block 21 has a fixing groove, and the supporting plate 20 adopts a matching structure. The bottom of the supporting plate 20 is inserted into the fixing groove of the positioning block 21 and fixed.

[0039] Preferably, the fixing groove of the positioning block 21 is a cross-shaped groove, and the supporting plate 20 is a cross-shaped plate.
