Detailed Implementation

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A fully automatic positioning device for a laser welding machine includes a laser welding machine body 1. A welding protective cover 2 is fixedly installed on the right side of the laser welding machine body 1. The welding protective cover 2 is used for the installation and fixation of a welding head 3, and also provides safety protection for the operator. A welding head 3 is fixedly installed on the inner wall of the laser welding machine body 1, directly opposite the welding protective cover 2. The welding head 3 is used to perform welding operations on the sheet metal parts to be welded, which are clamped and positioned by a circular placement seat 5. The welding head 3 is prior art and will not be described in detail here. The side of the laser welding machine body 1 facing the welding head 3... A circular positioning seat 4 is fixedly connected to the wall. A circular placement seat 5 is provided on the right side wall of the circular positioning seat 4. Four rectangular slots 6 are arranged in a cross shape on the annular side wall of the circular positioning seat 4. A propulsion assembly is provided in the four rectangular slots 6. The propulsion assembly includes several hydraulic cylinders 7, which are fixedly installed on the inner wall of the four rectangular slots 6 away from the circular placement seat 5. A pusher block 8 is fixedly connected to the piston rod of each of the hydraulic cylinders 7. The four pusher blocks 8 are associated with the clamping mechanism. The hydraulic cylinders 7 are used to drive the pusher blocks 8 to move horizontally along the direction of the rectangular slots 6.

[0018] A clamping mechanism is provided on the side wall of the circular placement base 5 away from the circular positioning base 4. The clamping mechanism includes four T-shaped limiting grooves 9 on the side wall of the circular placement base 5 away from the circular positioning base 4. The inner walls of the four T-shaped limiting grooves 9 are all connected to the annular side wall of the circular placement base 5. The four T-shaped limiting grooves 9 are respectively positioned opposite four rectangular grooves 6. A matching T-shaped limiting block 10 is slidably connected in each of the four T-shaped limiting grooves 9. When the T-shaped limiting block 10 moves along the T-shaped limiting groove 9, it can effectively provide limiting support for the clamping block 12, so that the pusher block 8 can drive the clamping block 12 to move and adjust smoothly. A rectangular opening 11 is provided between each of the four T-shaped limiting grooves 9 and the four rectangular grooves 6. The pusher block 8 passes through four rectangular openings 11 and is fixedly connected to the T-shaped limiting block 10. Each of the four T-shaped limiting blocks 10 is fixedly connected to a clamping block 12 at the end away from the circular placement seat 5. The T-shaped limiting block 10 and the clamping block 12 are integrally cast. The sheet metal part to be welded is placed on the circular placement seat 5. The hydraulic cylinder 7 in the four rectangular slots 6 is activated to drive the pusher block 8 to move and adjust along the direction of the rectangular openings 11. This allows the four pusher blocks 8 to drive the clamping block 12 to move along the direction towards the center of the circular placement seat 5 under the limiting action of the T-shaped limiting slots 9 and the T-shaped limiting block 10, and clamp and position the sheet metal part to be welded on the circular placement seat 5, which facilitates quick clamping and positioning of the sheet metal part to be welded.

[0019] Each of the four clamping blocks 12 has a groove 13 on its side wall facing the center of the circular placement base 5. Three hydraulic buffers 14 are inserted into each of the four grooves 13. Bolts 15 are fixedly connected between the clamping blocks 12 and the three hydraulic buffers 14. Rectangular abutments 16 are movably inserted into each of the four grooves 13. The three hydraulic buffers 14 on the same side are fixedly connected to the rectangular abutments 16. The rectangular abutments 16 are made of elastic rubber. When the four clamping blocks 12 move toward the center of the circular placement base 5 and clamp and position the sheet metal to be welded, the hydraulic buffers 14 in the grooves 13, together with the rectangular abutments 16 made of elastic rubber, provide buffer protection for the sheet metal to be welded, avoiding damage to the sheet metal to be welded during the clamping and positioning process.

[0020] In use, the sheet metal part to be welded is placed on the circular placement seat 5. The hydraulic cylinders 7 in the four rectangular grooves 6 are activated to drive the pusher blocks 8 to move and adjust along the direction of the rectangular opening 11. This causes the four pusher blocks 8 to drive the clamping blocks 12 to move towards the center of the circular placement seat 5 under the limiting action of the T-shaped limiting grooves 9 and T-shaped limiting blocks 10, thus clamping and positioning the sheet metal part to be welded on the circular placement seat 5. This facilitates quick clamping and positioning of the sheet metal part to be welded. When the four clamping blocks 12 move towards the center of the circular placement seat 5 and clamp and position the sheet metal part to be welded, the hydraulic buffer 14 in the groove 13, together with the rectangular abutment block 16 made of elastic rubber, provides buffer protection for the sheet metal part to be welded, avoiding damage to the sheet metal part to be welded during the clamping and positioning process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
