[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Please refer to the instruction manual appendix. Figure 1-5 This application provides a quick-change device for a laser cutting edge support block in a laser cutting equipment, comprising: a base 1 and a laser cutting edge support block 2. The base 1 has a length and width of 36mm and a height of 10mm. A set of fixing holes is provided on each of the left and right sides of the base 1. The fixing holes are fixedly connected to a worktable (not shown in the figure). Each set of fixing holes consists of two fixing holes 10 and a guide hole 11. The guide hole 11 is located between the two fixing holes 10, and a guide pin is provided inside the guide hole 11. The fixing holes 10 are fixedly connected to the worktable by bolts. The middle position of the seat 1 is fixedly connected to one end of the connecting support 3. The other end of the connecting support 3 is provided with a fixing block 4. The cross-section of the fixing block 4 is square, and the four sides of the fixing block 4 are rounded. The four corners of the upper surface of the fixing block 4 are chamfered. The upper end of the laser cutting support block 2 is provided with a contour groove 5, and the contour groove 5 is provided with a countersunk hole 6. The lower end of the laser cutting support block 2 is provided with a fixing slot 7. The fixing block 4 is fitted into the fixing slot 7. The fixing block 4 is provided with a threaded hole 8, and the threaded hole 8 is connected to the countersunk hole 6 by a bolt 9.

[0018] The base 1 has a 36×36mm square cross-section and a thickness of 10mm. It has six holes: two guide holes 11 for use with guide pins, and four fixing holes 10 with countersunk heads for use with bolts. The base 1 is fixed to the worktable of the laser cutting equipment (model: 1000W laser cutting machine) via guide pins (not shown in the figure) and bolts. The connecting support 3 is machined from cylindrical 45# round steel. One end connects to the base 1 and is further fixed by welding. The other end has a fixing block 4, which has a square cross-section, rounded edges, and a chamfered top. The side length of the fixing block 4 should be smaller than the cylindrical diameter of the connecting support 3. A 10mm deep M5×0.8 threaded hole 8 is designed in its center for fixing. The laser cutting support block 2 is designed with a contour groove 5 that conforms to the forging, used for quick positioning and fixing of the forging. The bottom of the laser cutting support block 2 has a fixing groove 7 that connects to the fixing block 4. The shape of the fixing groove 7 corresponds to that of the fixing block 4. The corners of the fixing groove 7 are rounded and chamfered. The side length of the fixing groove 7 is less than the maximum diameter of the connecting support 3. A through hole and a countersunk hole 6 are designed in the center of the contour groove 5 for further fixing with bolts 9. The consistent connection shape design ensures that different models of laser cutting support blocks 4 can be quickly replaced during production. This design also prevents rotation and shaking, ensuring stability and reliability during laser cutting production. When not in use, the fixing base 1 and connecting support 3 can be installed on the worktable of the laser cutting equipment (not shown in the figure). During operation, only the laser cutting support block 2 corresponding to the production part number needs to be installed. The connection position shape is designed with different sizes and specifications, but the overall shape is consistent, which can meet different production needs. After the laser cutting quick-change device and laser cutting support block 2 are installed, place the handle to be cut on the laser cutting support block 2, start the laser cutting equipment, set the corresponding cutting program, and the laser cutting work can be carried out. When it is necessary to change the product to be cut, the laser cutting support block can be quickly replaced.

[0019] Furthermore, the guide pin is a cylindrical pin, and the circumferential gap between the guide pin and the pin hole of the worktable is 0.1 mm on one side; this improves installation efficiency and prevents the cutting edge position from deviating during the shearing process.

[0020] Furthermore, the circumferential gap between the connecting support 3 and the laser cutting block 2 is 0.05 mm when they are assembled; this improves installation efficiency and prevents the cutting position from deviating during the cutting process.

[0021] Furthermore, both the base 1 and the connecting support 3 are made of 45# steel; the heat treatment hardness is HRC35~40, and the tempering temperature is not lower than 500℃. This improves the rigidity and durability of the fixed base 1 and the connecting support 3.

[0022] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: By setting a fixing block 4 on the connecting support 3 and cooperating with the fixing slot 7 on the laser cutting edge support block 2, the connecting support 3 and the laser cutting edge support block 2 can be quickly spliced ​​together, realize quick replacement, reduce installation time, improve installation efficiency, and also effectively prevent the cutting edge position from deviating during the cutting process.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
