[0003] Sheet metal parts include parts with regular shapes and parts with special shapes. Parts with regular shapes can be clamped using traditional positioning clamping plates, but they cannot adapt to the positioning and fixation of special-shaped sheet metal parts. Different clamping tools are often required for clamping special-shaped sheet metal parts with different configurations, which is rather troublesome. Based on this, a special-shaped sheet metal parts processing and positioning tool is proposed herein, which is very important to realize the rapid replacement of the clamping head and the positioning of special-shaped sheet metal parts with different configurations.

[0006] Preferably, each of the positioning parts comprises a clamping plate, a clamping surface of the clamping plate is provided with a clamping groove, and the clamping groove is one of a square groove, a triangular groove, a polygonal groove or a circular groove.

[0007] Preferably, the driving part is a cylinder, and the cylinder is installed on the upper end surface of the base plate near the edge.

[0008] Preferably, a mounting block is fixed to the output end of the cylinder, a T-shaped slot is provided on the upper end surface of the mounting block, a T-shaped plug-in block is fixed to the side of the clamping plate away from the clamping slot, and the T-shaped plug-in block is inserted and matched with the T-shaped slot.

[0009] Preferably, the side wall of the mounting block is connected to a frame body, an embedding rod is passed through the frame body, an embedding groove is opened on the outer wall of the T-shaped plug block, the inner end of the embedding rod can be embedded in the embedding groove, a fixing plate is connected to the outer wall of the embedding rod and located inside the frame body, a spring is connected to the outside of the embedding rod and located between the fixing plate and the frame body, and a pull ring is installed on the outer end of the embedding rod.

[0010] Preferably, a chip collecting groove is provided in the middle of the upper end surface of the bottom plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model is provided with a detachable positioning part, which is convenient for removal and replacement. When dealing with special-shaped sheet metal parts of different configurations, it is only necessary to replace the clamping plates with different structural clamping grooves to position and fix the sheet metal parts. There is no need to equip and produce a variety of positioning tooling, which is more flexible and convenient.

[0013] (2) When the T-shaped insert block is inserted into the T-shaped slot, the pull ring can be pulled outward first to compress the spring. At this time, the inner end of the embedded rod retracts into the outer wall of the mounting block. After the T-shaped insert block is inserted, the pull ring can be loosened. During the process of the spring returning to its original state, the inner end of the embedded rod can be driven to embed into the embedded slot, thereby limiting the upward movement of the T-shaped insert block from leaving the T-shaped slot, thereby ensuring the stability of the splint installation.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Figure 1This is a top view of the utility model. As shown in the figure, the special-shaped sheet metal parts processing and positioning tooling includes a base plate 1. The upper middle part of the base plate 1 is a positioning area. A chip collection groove 14 is opened in the middle of the upper end surface of the base plate 1. The positioning area is used to place the special-shaped sheet metal parts to be positioned and fixed. The debris generated by the processing can fall into the chip collection groove 14, which is conducive to subsequent centralized processing. A plurality of positioning components are arranged in a circular array on the upper end surface of the base plate 1 and located at the periphery of the positioning area. The positioning components clamp and fix the special-shaped sheet metal parts. Each positioning component includes a positioning part and a driving part. The driving part is used to drive the positioning part to approach or move away from the center of the positioning area. The positioning part is detachably mounted on the driving part, and the detachable positioning part is easy to remove and replace.

[0020] Among them, see Figure 1 As shown, each positioning part includes a clamping plate 6, and a clamping groove 7 is opened on the clamping surface of the clamping plate 6. The clamping groove 7 is one of a square groove, a triangular groove, a polygonal groove or a circular groove. For special-shaped sheet metal parts with different configurations, the clamping plate 6 with clamping grooves 7 of different structures can be replaced to position and fix the sheet metal parts.

[0021] In a specific embodiment of the utility model, the driving part is a cylinder 2, which is installed on the upper end surface of the base plate 1 near the edge, and a mounting block 3 is fixed to the output end of the cylinder 2. A T-shaped slot 4 is provided on the upper end surface of the mounting block 3. A T-shaped plug-in block 5 is fixed to the side of the clamping plate 6 away from the clamping groove 7, and the T-shaped plug-in block 5 is inserted and matched with the T-shaped slot 4.

[0022] As described above, the cylinder 2 can be used to drive the mounting block 3 to move, and then the clamping plate 6 can be used to clamp and position the special-shaped sheet metal parts to be processed.

[0023] When installing the clamping plate 6, the T-shaped insert block 5 is inserted into the T-shaped slot 4 from top to bottom, and then the position is limited.

[0024] In addition, see Figure 1-Figure 3 As shown, the side wall of the mounting block 3 is connected to a frame body 10, an embedding rod 9 is passed through the frame body 10, an embedding groove 8 is opened on the outer wall of the T-shaped plug block 5, the inner end of the embedding rod 9 can be embedded in the embedding groove 8, a fixing plate 12 is connected to the outer wall of the embedding rod 9 and located inside the frame body 10, a spring 11 is connected to the outside of the embedding rod 9 and located between the fixing plate 12 and the frame body 10, and a pull ring 13 is installed on the outer end of the embedding rod 9.

[0025] Through the above technical solution:

[0026] When in use, when the T-shaped plug block 5 is inserted into the T-shaped slot 4 from top to bottom, the pull ring 13 can be pulled outward first to compress the spring 11. At this time, the inner end of the embedded rod 9 retracts into the outer wall of the mounting block 3. After the T-shaped plug block 5 is inserted, the pulled pull ring 13 can be released. During the process of the spring 11 returning to its original state, the inner end of the embedded rod 9 can be driven to embed into the embedded groove 8, which can limit the T-shaped plug block 5 from moving up and out of the T-shaped slot 4 to ensure the stability of the installation of the splint 6.
