[0025] Referring to the attached Figure 1-2 , the present utility model provides a clamping and placing device, including:

[0026] A clamping mechanism 100, the clamping mechanism 100 includes a fixing bracket 110 and symmetrically arranged jaw units 120. The jaw units 120 are fixed to the fixing bracket 110, and the jaw units 120 can approach or move away from each other;

[0027] The lifting mechanism 200 includes a positioning frame 210 and a lifting cylinder 220. The positioning frame 210 is pivotally connected to the clamping mechanism 100. The lifting cylinder 220 is used to drive the positioning frame 210 to move upward and downward.

[0028] The horizontal cylinder 300 has one end hinged to the positioning frame 210 , and the other end hinged to the fixing frame 110 .

[0029] Based on the above technical features, the clamping or loosening of the object is achieved through the relatively arranged clamping claw units 120, and through the pivot connection between the positioning frame 210 and the fixing frame 110, the lifting cylinder 220 drives the positioning frame 210 to rise and fall while driving the clamping mechanism 100 to achieve lifting and placement processing, and the positioning frame 210 and the fixing frame 110 are hingedly connected by the horizontal cylinder 300. Since the positioning frame 210 and the fixing frame 110 are pivotally arranged, when the horizontal cylinder 300 is dragged horizontally, the two ends rotate and the pivot rotation between the positioning frame 210 and the fixing frame 110 is achieved, so that the placement angle of the object of the clamping mechanism 100 is adjusted, and the control placement of the clamping mechanism 100 is achieved through the linkage between the lifting cylinder 220 and the horizontal cylinder 300, which simplifies the equipment components and can meet the adjustment of the horizontal angle and lifting height.

[0030] Furthermore, the clamping unit 120 includes a clamping member 121 and a clamping cylinder 122. The clamping cylinder 122 is fixed to the fixing frame 110. The driving end of the clamping cylinder 122 is transmission-connected to the clamping member 121. The clamping cylinder 122 is used to drive the clamping members 121 to move closer to or away from each other, thereby achieving the relatively arranged clamping members 121 to move closer to or away from each other.

[0031] Specifically, the clamping member 121 includes a connecting member 121A and a clamping member 121B. One end of the connecting member 121A is transmission-connected to the clamping cylinder 122, and the clamping member 121B is connected to the other end of the connecting member 121A. The movement of the clamping member 121B is controlled by driving the connecting member 121A, and an enclosure structure is formed by the horizontally arranged clamping member 121B and the vertically arranged connecting member 121A, thereby satisfying the clamping and movement of the object.

[0032] It also includes a rotating mechanism 400, the clamping jaw member 121B is hinged with the connecting member 121A, and the rotating mechanism 400 is transmission-connected with the clamping jaw member 121B, and is used to drive the clamping jaw member 121B to rotate, thereby realizing the rotation of the clamping jaw member 121B in the vertical direction. By making the relatively arranged clamping jaw members 121B in a hinged state, the rotation adjustment of the object in the horizontal direction is realized.

[0033] Specifically, the rotating mechanism 400 includes an abutting cylinder 410 and a dial assembly 420. The free end of the abutting cylinder 410 is drivingly connected to the input end of the dial assembly 420, and the output end of the dial assembly 420 is drivingly connected to the jaw member 121B. The rotation of the output end of the dial assembly 420 drives the jaw member 121B to rotate hingedly on the connecting member 121A. The input end of the dial assembly 420 is hinged to the abutting cylinder 410. When the abutting cylinder 410 pushes or contracts, the dial assembly 420 rotates forward or reversely, thereby realizing the rotation drive of the jaw member 121B in the horizontal direction.

[0034] Further, a preloading mechanism 500 is included. The preloading mechanism 500 is disposed on the top of the jaw member 121B. The preloading mechanism 500 can approach or move away from the jaw member 121B. A pressing space is formed between the jaw members 121B through the preloading mechanism 500, thereby realizing the stable positioning of the workpiece and facilitating the clamping of the workpiece by the jaw members 121B approaching each other.

[0035] Specifically, the preloading mechanism 500 includes a pressing cylinder 510 and a pressing member 520. The pressing member 520 is arc-shaped. The pressing cylinder 510 is fixed to the fixed frame 110. The pressing cylinder is drivingly connected to the pressing member 520. The pressing cylinder is used to drive the pressing member 520 to approach or move away from the jaw member 121B in the horizontal direction. The abutment against different workpieces is better realized through the arc-shaped setting, covering more positions on the horizontal plane.

[0036] In this embodiment, both ends of the horizontal cylinder 300 are on the same side. One end of the horizontal cylinder 300 is connected to the end of the positioning frame 210, and the other end of the horizontal cylinder 300 is hinged to a position near the middle of the fixed frame 110, which is convenient for increasing the rotation stroke of the fixed frame 110 and better realizing the rotation of the jaw mechanism in the horizontal direction.

[0037] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
