[0004] However, existing laser welding fixtures also have certain shortcomings. Most existing laser welding fixtures use a fixed-position clamping method to hold the workpiece, which makes it difficult to adjust the welding position of the workpiece, which is very inconvenient for subsequent welding operations. Utility Model Content

[0021] 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.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A laser welding fixture includes a base 1, an annular groove 2 at the upper end of the base 1, a support plate 3 fixedly connected to the right end of the base 1, a motor 4 fixedly mounted at the upper end of the support plate 3, the output shaft of the motor 4 being rotatably connected to the support plate 3, and a table 5 fixedly sleeved on the outside of the output shaft of the motor 4, the table 5 being rotatably connected to the support plate 3.
[0023] The output shaft of motor 4 has a positioning hole 6. The inner wall of the support plate 3 is slidably connected to a positioning component 7. The horizontal part of the positioning component 7 is slidably connected to the positioning hole 6. An elastic component 8 is bonded to the end plate of the positioning component 7. The other end of the elastic component 8 is bonded to the support plate 3. A support rod 9 is fixedly connected to the lower end of the table 5.
[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4Multiple positioning holes 6 are provided, and the multiple positioning holes 6 are arranged in a ring array on the output shaft of motor 4. The positioning holes 6 are provided to facilitate the use of positioning parts 7 for snap-fit. The lower end of the support rod 9 is fixedly connected to a movable ball 10, which contacts the annular groove 2. Through the cooperation of the movable ball 10 and the annular groove 2, the table surface 5 can be moved and supported. Two elastic elements 8 are provided, and the two elastic elements 8 are symmetrically distributed on the end plate of positioning part 7. The positioning part 7 can be connected and used through the setting of elastic elements 8.
[0025] Please see Figure 1 , Figure 2 , Figure 3 A clamping mechanism 11 is provided on the table surface 5. The clamping mechanism 11 includes guide plates 111. Guide plates 111 are fixedly connected to the front and rear ends of the table surface 5. A guide block 112 is slidably sleeved on the outer side of each guide plate 111. A clamping plate 113 is fixedly connected to the upper end of the guide block 112. The clamping plate 113 is slidably connected to the table surface 5. Multiple friction grooves are opened on the end face of the clamping plate 113. The multiple friction grooves are evenly distributed on the clamping plate 113. The friction effect of the clamping plate 113 can be improved by setting the friction grooves. The left end of the table surface 5 is fixed. A second motor 114 is installed, and a first gear 115 is fixedly sleeved on the outer side of the output end of the second motor 114. A second gear 116 meshes with the first gear 115, and a positive and negative threaded screw 117 is fixedly sleeved inside the second gear 116. The positive and negative threaded screw 117 is threadedly connected to both clamping plates 113. Through the cooperation of the second motor 114, the first gear 115 and other structures, the positive and negative threaded screw 117 can be driven to rotate, thereby driving the two clamping plates 113 to move and automatically clamp the workpiece.
[0026] The specific implementation process of this utility model is as follows: When in use, the workpiece is placed on the table 5, and the output end of the second motor 114 is started to rotate, which drives the first gear 115 to rotate. Under the meshing relationship, the first gear 115 drives the second gear 116 to rotate, which in turn drives the positive and negative threaded screw 117 to rotate. Under the threaded connection relationship, since the threads on the surface of the positive and negative threaded screw 117 are symmetrically distributed and in opposite directions, the two clamping plates 113 can be driven to move towards each other, and the workpiece on the table 5 is automatically clamped and fixed.
[0027] The starting motor 4 drives the output shaft to rotate, thereby rotating the table 5. The table 5 can be deflected to adjust the position of the workpiece. When the table 5 deflects, it can drive the support rod 9 to deflect, which in turn drives the moving ball 10 to slide along the inner wall of the annular groove 2 to support the table 5 and ensure the stability of the table 5's deflection.
[0028] When the output shaft of motor 4 rotates, the inner wall of the positioning hole 6 presses against the positioning member 7, pushing the positioning member 7 to move. The elastic member 8 deforms, eventually causing the positioning member 7 to disengage from the positioning hole 6. Under the action of force, the positioning member 7 moves along the surface of the output shaft of motor 4. When the positioning member 7 slides into the next positioning hole 6, the elastic member 8 restores its deformation, pulling the positioning member 7 into the positioning hole 6, limiting the output shaft of motor 4, positioning the table 5, and finally adjusting and positioning the workpiece.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
