[0026] The utility model is described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, an automatic feeding and positioning clamping mechanism of the utility model comprises a clamping device 1 and a feeding device 2 used in conjunction with the clamping device 1, wherein the clamping device 1 is used to clamp the material to be processed and load the material to be processed onto the feeding device 2, wherein the feeding device 2 is used to transport the material to be processed clamped and loaded via the clamping device 1, wherein the feeding device 2 comprises a workbench 21, a linear module 22 for driving the workbench 21 to move, a pressing assembly 23 arranged on one side of the workbench 21, a moving piece 24 arranged on the other side of the workbench 21, and a moving cylinder 25 for driving the moving piece 24 to pass through the pressing assembly 23, wherein the moving direction of the workbench 21 is perpendicular to the moving direction of the moving piece 24.

[0028] During operation, the material to be processed is first clamped by the clamping device 1 and transported to the feeding device 2. The linear module 22 drives the workbench 21 to move toward the position of the clamping device 1, so that the position of the pressing component 23 faces the position of the clamping device 1. Then, the material moving member 24 is driven by the material moving cylinder 25 to pass through the pressing component 23, so that the material moving member 24 extends outward to the outside of the feeding device 2, so that the clamping device 1 clamps the material to be processed and accurately places the material to be processed on the material moving member 24. The material moving cylinder 25 drives the material moving member 24 to retract inward to the pressing component 23. In the material assembly 23, the upper surface of the material to be processed placed on the material moving piece 24 is pressed downward by the material pressing assembly 23, and the pressing contact area is large, so as to press and fix the position of the material to be processed, and finally the material to be processed pressed and fixed by the material pressing assembly 23 is transported to the processing station by the feeding device 2 for corresponding processing operations. The operation is convenient and efficient, and the positioning accuracy is high. The workbench 21 moves horizontally, and the material moving piece 24 moves longitudinally. The moving direction of the workbench 21 is perpendicular to the moving direction of the material moving piece 24, which is conducive to the dual role of directional transfer and position fixing of the material to be processed. The utility model can press and fix the position of the material, has high positioning accuracy, is simple and convenient to operate, and improves production efficiency and production quality.

[0029] The pressing assembly 23 of this embodiment includes a pressing seat 231, a pressing block 232 arranged on the pressing seat 231, and a pressing cylinder 233 for driving the pressing block 232 to approach or move away from the material moving piece 24. The pressing block 232 is a T-shaped structure, and both sides of the pressing seat 231 are protruding with limit blocks 234. The limit blocks 234 stop and resist the pressing block 232. The material moving piece 24 is provided with a storage groove 235 at one end away from the material moving cylinder 25. Specifically, first, the clamping device 1 clamps the material to be processed and accurately places the material to be processed in the storage slot 235 of the material moving piece 24. Then, the material moving cylinder 25 drives the material moving piece 24 to retract inward into the material pressing seat 231, and drives the material pressing block 232 to move downward through the material pressing cylinder 233 and make the material pressing block 232 close to the material moving piece 24. Since the material pressing block 232 is a T-shaped structure, through the setting of two limit blocks 234, the two limit blocks 234 can simultaneously block and resist both sides of the material pressing block 232, so that the stopping force on both sides of the material pressing block 232 is balanced left and right, avoiding the material pressing block 232 from being skewed due to uneven force, thereby limiting the up and down movement of the material pressing block 232 in the material pressing seat 231, ensuring that the material pressing block 232 applies appropriate pressing force to the material to be processed, and the positioning effect is good.

[0030] The pressing assembly 23 of this embodiment also includes an adjustment plate 236, a first slider 237 arranged on the adjustment plate 236, and a first guide rail 26 arranged on the workbench 21. The front side of the adjustment plate 236 is connected to the pressing seat 231, and the rear side of the adjustment plate 236 is slidably connected to the first guide rail 26 through the first slider 237. A stop plate 27 is arranged on the top of the workbench 21, and a fine-tuning screw 28 is arranged on the bottom of the workbench 21, and the fine-tuning screw 28 abuts against the adjustment plate 236. Specifically, the front side surface of the adjustment plate 236 is connected to the pressure seat 231, and the rear side surface of the adjustment plate 236 is slidably connected to the first guide rail 26 through the first slider 237. A stop plate 27 is provided on the top of the workbench 21, and a fine-tuning screw 28 is provided on the bottom of the workbench 21. In order to facilitate the adjustment of the position of the pressure assembly 23 to accurately align with the position of the clamping device 1, the fine-tuning screw 28 is abutted against the adjustment plate 236. The fine-tuning screw 28 is rotated to contact the bottom wall of the adjustment plate 236, so as to fine-tune the height of the adjustment plate 236, so that the adjustment plate 236 slides up and down along the first guide rail 26 through the first slider 237, and the position fine-tuning effect is good. The stop plate 27 blocks and abuts the top wall of the adjustment plate 236, effectively limiting the up and down fine-tuning stroke of the adjustment plate 236, and the limiting effect is good.

[0031] A mounting seat 29 is provided on the rear side of the adjustment plate 236 of this embodiment, and the material moving cylinder 25 is connected to the mounting seat 29. The adjustment plate 236 and the material pressing seat 231 are respectively provided with a first through hole 238 and a second through hole 239, and the central axes of the first through hole 238 and the second through hole 239 coincide with each other. The output end of the material moving cylinder 25 passes through the first through hole 238 and the second through hole 239 in sequence and is drivingly connected to the material moving member 24. Specifically, a through groove (not shown) is opened in the middle of the workbench 21, and the through groove can allow the mounting seat 29 and the material moving cylinder 25 to pass through. The material moving cylinder 25 is installed on the rear side of the adjustment plate 236 through the mounting seat 29, so that the adjustment plate 236 is used to synchronously drive the material moving cylinder 25 to fine-tune the position. The central axes of the first through hole 238 and the second through hole 239 coincide with each other, ensuring accurate alignment between the adjustment plate 236 and the material pressing seat 231, so that the output end of the material moving cylinder 25 passes through the first through hole 238 and the second through hole 239 in turn and is driven and connected to the material moving member 24, thereby improving assembly efficiency and having a compact structure, so that the material moving cylinder 25 drives the material moving member 24 to extend out of the material pressing seat 231 or retract into the material pressing seat 231.

[0032] The clamping device 1 of this embodiment includes a moving seat 11, a driving cylinder 12 for driving the moving seat 11 to move, a clamping claw cylinder 13 arranged on the moving seat 11, and a clamping claw 14 drivingly connected to the clamping claw cylinder 13, wherein the clamping claw cylinder 13 controls the clamping claw 14 to pick up and place the material to be processed. Specifically, the clamping claw cylinder 13 is arranged on the moving seat 11, and the driving cylinder 12 drives the moving seat 11 to approach the feeding device 2, so that the clamping claw cylinder 13 controls the clamping claw 14 to clamp and pick up the material to be processed to the feeding device 2, and the material transfer efficiency is high.

[0033] The clamping device 1 of this embodiment further includes a base 15 and a second guide rail 16 disposed on the base 15, and the movable seat 11 is provided with a second slider 17 slidably connected to the second guide rail 16. Specifically, when the driving cylinder 12 drives the movable seat 11 to move back and forth, the movable seat 11 is slidably connected to the second guide rail 16 through the second slider 17, so that the movable seat 11 moves smoothly and stably with low friction resistance.
