DETAILED DESCRIPTION
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-4 The laser cutting auxiliary device shown includes a table 1, a fixture base 2, a pressure ring 3, and a cooling element 4. The fixture base 2 has a cylindrical structure, and its bottom is fixed to the table 1 by the pressure ring 3. A disc-shaped workpiece 8 is fitted onto the top of the fixture base 2. The fixture base 2 supports and mounts the disc-shaped workpiece 8 to cooperate with the laser cutter to complete the laser drilling operation. The fixture base 2 has a through-hole 21 for collecting waste rings cut off during the laser cutting process. Figure 5 As shown, the top of the disc-shaped workpiece 8 is drilled along the laser cutting line 81. Since the laser cutting line 81 is relatively close to the inner wall of the workpiece, the fixture 2 can only be designed as a thin-walled cylindrical structure. During laser cutting, the top of the fixture 2 will experience high temperature. To prevent high-temperature damage to the top of the fixture 2, this invention designs a cooling element 4 to solve the above problem. Each fixture 2 is equipped with a cooling element 4, which includes a groove base 41 and a groove ring 42. The groove ring 42 is vertically connected to the groove base 41 and is fitted onto the outside of the fixture 2. The groove base 41 and the groove ring 42 form a water tank structure. A water cavity 43 is formed between the groove ring 42 and the fixture 2. The top of the water cavity 43 is open so as not to affect the installation of the disc-shaped workpiece 8. The water cavity 43 is filled with cooling water 44. The fixture 2 and the disc-shaped workpiece 8 are immersed in the cooling water 44. The cooling water 44 has a cooling effect on the fixture 2 and the disc-shaped workpiece 8 to suppress the temperature rise of the top of the fixture 2. After the cooling element 4 is installed, the temperature of the top of the fixture 2 is good, and there is no longer a problem of high temperature deformation or high temperature damage. In this way, the disc-shaped workpiece 8 can be continuously fed on the fixture 2 to complete the laser drilling operation. This utility model has a very good practical effect.
[0022] like Figure 1 As shown, the table 1 has waist-shaped grooves 11 at all four corners. This utility model can be fixed to the operating platform of the laser equipment through the table 1, which is convenient for modification and installation.
[0023] like Figure 3As shown, the bottom of the fixture 2 is turned outward to form a raised edge 22, and the inner hole of the pressure ring 3 is formed with a pressing flange 31. The pressing flange 31 of the pressure ring 3 can press against the raised edge 22 of the fixture 2. The pressure ring 3 and the platform 1 are fixedly connected by bolts. When installing the fixture 2, first place it in position, then put on the pressure ring 3, and then lock and fix the fixture 2 by the pressure ring 3. This structure makes the installation and replacement of the fixture 2 very convenient.
[0024] like Figure 3 As shown, the groove base 41 adopts a Z-shaped cross-section design, and the groove ring 42 is welded to the outer edge of the groove base 41. The groove ring 42 and the groove base 41 are designed separately for easy processing. The groove ring 42 and the groove base 41 form a water tank structure. When the groove base 41 is installed, the inner ring hole surface of the groove base 41 is in contact with the outer wall of the tooling seat 2. A sealing ring 411 is installed on the inner ring hole surface of the groove base 41. The sealing ring 411 forms a sealed connection between the groove base 41 and the outer wall of the tooling seat 2, which can ensure the sealing of the side and bottom of the water cavity 43.
[0025] like Figure 3 As shown, the water level of the cooling water 44 in the water cavity 43 should not be too high or too low. If it is too high, it will overflow the top of the water cavity 43, and if it is too low, the cooling effect will be poor. In actual application, it has been found that the optimal water level of the cooling water 44 is 85%-90% of the total height of the water cavity 43. At this water level, most of the disc-shaped workpiece 8 and the tooling seat 2 are surrounded by the cooling water 44, resulting in the best cooling effect. Moreover, the cooling water 44 will not overflow and will not cause water pollution around the equipment.
[0026] like Figure 1 As shown, a tooling base 2 and a cooling element 4 form a pair. A pair of tooling bases 2 and cooling elements 4 can only complete the laser cutting operation of one disc-shaped workpiece 8. In order to improve production efficiency, this utility model has several pairs of tooling bases 2 and cooling elements 4 installed on the table 1. In this way, multiple disc-shaped workpieces 8 can be laser cut continuously. When the next disc-shaped workpiece 8 is to be operated, the previous pair of tooling bases 2 and cooling elements 4 can be used to replace the new disc-shaped workpiece 8.
[0027] like Figure 2As shown, the laser cutting auxiliary device further comprises a water inlet main pipe 5 and a water return main pipe 6, both of which are connected to each cooling element 4, each cooling element 4 has a water inlet branch and a water return branch, and the water temperature is stabilized by circulating the cooling water 44 during the laser cutting operation, and a water valve 7 is installed on each connecting branch of the water inlet main pipe 5 and the water return main pipe 6, the water valve 7 can control the opening and closing of the water inlet branch and the water return branch, the water inlet branch and the water return branch on one cooling element 4 need to be opened or closed at the same time, and when a certain tool holder 2 is not used, the water inlet branch and the water return branch on the matching cooling element 4 need to be closed at the same time.
[0028] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application shall be considered as the protection scope of the present application.
