A groove 402 is opened in the middle of the supporting tray 401, and a lifting plate 403 is provided on the inner side of the groove 402 for sliding and rotating. A motor carrier plate 406 is also provided on the lower side of the supporting tray 401, and a plurality of push-pull cylinders C407 are fixedly distributed circumferentially on the upper side of the motor carrier plate 406, and the upper end of the push-pull cylinder C407 is fixedly connected to the supporting tray 401, and a rotating motor 404 is fixed to the lower side of the motor carrier plate 406, and the output end of the rotating motor 404 rotates and extends into the groove 402 and is fixedly connected to the middle of the bottom of the lifting plate 403.

[0033] The height of the supporting plate 401 can be adjusted by the push-pull cylinder B405, and can be well adapted to the clamping blocks A202 and B203. When the workpiece 3 needs to be lifted, the lifting plate 403 can be made to protrude from the surface of the supporting plate 401 by controlling the shortening of the push-pull cylinder C407, thereby lifting the workpiece 3. The rotating motor 404 can also be started as needed to drive the lifting plate 403 to rotate, thereby driving the workpiece 3 to turn, thereby meeting the needs of flexible welding.

[0035] The present invention improves the efficiency and reliability of clamping the workpiece 3 by optimizing the clamping assembly 2 and the supporting assembly 4. In the test of producing 1,000 welding products, the number of welding defects (such as pores, cracks, etc.) produced by the traditional device was 70-90, and the defect rate was 7%-9%; while the number of welding defects produced by the device of the present invention was 10-20, and the defect rate was only 1%-2%. The clamping time of the traditional device is an average of 2-5 minutes per piece, while the clamping time of the device of the present invention can be shortened to 1-1.5 minutes per piece through the quick clamping mechanism and automatic adjustment function. For example, in the mass production of a certain model of mechanical parts, 90-100 pieces can be produced per day (calculated based on 8 hours of working time) using the traditional device, while 400-500 pieces can be produced per day using the device of the present invention.

[0036] The above embodiment of the present invention provides a product welding clamping device, and its working principle is as follows: The support assembly 4 is installed on the device base 1 through multiple push-pull cylinders B405 at the bottom, and the height of the support tray 401 can be adjusted as needed to adapt to different processing requirements.

[0037] A groove 402 is provided in the middle of the tray 401, which contains a lifting plate 403 that can slide and rotate. When the workpiece 3 to be processed needs to be lifted, the lifting plate 403 is lifted from the groove 402 by controlling the push-pull cylinder C407 located at the lower side of the tray 401 to be shortened, thereby lifting the workpiece 3 to be processed.

[0038] The rotating motor 404 is fixed below the motor carrier plate 406 and connected to the bottom of the lifting plate 403 through its output end, so as to realize the rotation function of the workpiece 3 to be processed, and facilitate the angle adjustment during the welding process.

[0039] The clamping assembly 2 is composed of an inverted U-shaped frame B216, a placement plate 214, a turntable 213, an inverted U-shaped frame A210, an angle frame 208, etc. The placement plate 214 can be adjusted along the inverted U-shaped frame B216, and the turntable 213 allows rotation, which increases the flexibility of the clamping position.

[0040] The push-pull cylinder A209 on the angle frame 208 drives the top pressure frame 201 to move up and down, and the clamping block A202 fixed on the lower side of the top pressure frame 201 is used to apply pressure to the top of the workpiece 3 to be processed.

[0041] The side pressure frame 204 on the guide rod 207 moves toward the side of the workpiece 3 to be processed when the push-pull cylinder A209 is shortened through the wedge block B206 that cooperates with the wedge block A205, so that the clamping block B203 clamps the side of the workpiece.

[0042] The spring is arranged at one end of the guide rod 207 away from the angle frame 208 to ensure that the side pressure frame 204 can return to its original position after release. In addition, by adjusting and locking the position of the wedge block B206, the pressing position can be flexibly adjusted according to the needs of different workpieces 3 to be processed.

[0043] In summary, the welding clamping device of this product realizes height adjustment and angle rotation through the support component 4, and combined with the two adjustable clamping components 2, it realizes efficient and reliable top and side clamping and fixation of the workpiece 3 at the same time, meeting the needs of diversified welding processes.

[0044] The PLC controller disclosed in the prior art can be used to control each component. The model and circuit connection of each component are not specifically limited and can be flexibly set in actual application.

[0045] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.
