DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The clamping component includes four rotating components, a driving component and an adsorption component. A mounting seat 21 is fixedly installed at the bottom of the fixed track 1. Four mounting holes 22 are opened on the top of the mounting seat 21, and the four mounting holes 22 are respectively arranged at the four corners of the mounting seat 21. When in use, rivets or screws can be used to pass through each mounting hole 22 in turn to fix the device at a specified position.

[0030] A moving seat 2 is slidably connected in the fixed track 1, and the moving seat 2 is driven by a moving assembly. The moving assembly includes a screw rod 19 rotatably installed in the fixed track 1, and the screw rod 19 is threadedly penetrated through the outer side of the moving seat 2. A third motor 20 for driving the screw rod 19 is fixedly installed on the outer side of the fixed track 1. During use, the third motor 20 can also be started to drive the screw rod 19 to rotate, so that the moving seat 2 can drive the adjustable robot arm 4 to move along the fixed track 1, so as to realize the adjustment of the position of the mechanical workpiece clamped by the device, thereby increasing the use range of the device.

[0031] A rotating column 3 is rotatably installed on the top of the moving base 2, and the rotating column 3 is driven by a rotating component.

A second gear 18 is meshed with the outside of the first gear 17, and the second gear 18 is fixedly sleeved on the surface of the rotating column 3. During use, the second motor 16 can also be controlled to drive the first gear 17 to rotate, and then the second gear 18 meshed with it can be used to drive the rotating column 3 and the adjustable robot arm 4 to rotate, thereby further adjusting the pickup range of the adjustable robot arm 4, thereby further increasing the use range of the device.

[0032] A hollow disk 5 is fixedly mounted on one end of the adjustable robot arm 4 away from the rotating column 3. Four rotating components are distributed in a circular array at the bottom of the hollow disk 5, and the rotating components include a fixed bracket 6 fixedly mounted on the bottom of the hollow disk 5. A worm gear 7 is rotatably mounted on the fixed bracket 6, and the worm gear 7 movably passes through the bottom of the hollow disk 5. Four through holes are opened at the bottom of the hollow disk 5, and the through holes are matched with the worm gear 7 to provide a rotation space for each worm gear 7.

[0033] A clamping claw 8 is fixedly installed on the side of the worm wheel 7, and a worm 9 is meshed with one end of the worm wheel 7 located in the hollow disk 5. A fixing plate 23 is movably sleeved on the outer wall of each worm 9, and the fixing plate 23 is vertically fixedly installed in the hollow disk 5, thereby increasing the stability of each worm 9 during rotation.

[0034] The end of the worm 9 away from the center of the hollow disk 5 is rotatably mounted on the inner wall of the hollow disk 5, and the other end of the worm 9 is fixedly mounted with a driven bevel gear 10; the driving assembly is used to drive the four rotating assemblies, and the driving assembly includes a first motor 11 fixedly mounted on the top of the hollow disk 5, the output shaft end of the first motor 11 is vertically downward and fixedly mounted with a driving bevel gear 12, and the driving bevel gear 12 is meshed with each driven bevel gear 10. When clamping a mechanical workpiece, each clamping jaw 8 is first placed in a fixed position by controlling the moving assembly, the rotating assembly and the adjustable robot arm 4. The outer side of the workpiece to be clamped, at this time, start the first motor 11 again to drive the active bevel gear 12 to rotate, and use each driven bevel gear 10 meshing therewith to make each worm 9 drive the corresponding worm 9 to rotate, and then the worm 9 drives each clamping jaw 8 to rotate the center of the hollow disk 5 through the worm wheel 7 meshing therewith, until each clamping jaw 8 is tightly pressed against the surface of the mechanical workpiece, so that the mechanical workpiece can be firmly clamped, and at the same time, by changing the distance between the ends of each clamping jaw 8, it can also adapt to the clamping of mechanical workpieces of different sizes, thereby improving the application range of the device.

[0035] Furthermore, the adsorption component includes a suction pump 13 fixedly mounted on the inner bottom wall of the hollow disk 5, the air extraction end of the suction pump 13 passes through the inner bottom wall of the hollow disk 5 and is fixedly connected to a suction cup 14, and the suction cup 14 is fixedly mounted on the bottom of the hollow disk 5, and a plurality of negative pressure adsorption holes 15 are provided at the bottom of the suction cup 14, and a rubber sealing ring 24 is commonly provided around the periphery of the plurality of negative pressure adsorption holes 15, and the rubber sealing ring 24 is fixedly mounted on the bottom of the hollow disk 5.

At the same time, when the suction cup 14 is close to the surface of the mechanical workpiece, the sealing between the suction cup 14 and the mechanical workpiece can be increased under the action of the rubber sealing ring 24, so as to improve the adsorption effect of the suction cup 14 on the mechanical workpiece, thereby improving the versatility of the device.

[0036] The working principle of the present invention is:

[0037] When in use, firstly, according to the position of the mechanical workpiece to be clamped, the third motor 20 is controlled to drive the screw 19 to rotate, so that the movable seat 2 can drive the adjustable robot arm 4 to move along the fixed track 1, and the second motor 16 is controlled to drive the first gear 17 to rotate, and the second gear 18 meshing therewith can drive the rotating column 3 and the adjustable robot arm 4 to rotate. At the same time, the automatic adjustment of the adjustable robot arm 4 is coordinated to realize the adjustment of the position of the mechanical workpiece clamped by the device, until each clamping claw 8 is placed on the periphery of the mechanical tool to be clamped;

[0038] Then, the first motor 11 is started to drive the active bevel gear 12 to rotate, and each driven bevel gear 10 meshing therewith is used to make each worm 9 drive the corresponding worm 9 to rotate, and then the worm 9 drives each clamping jaw 8 to rotate around the center of the hollow disk 5 through the worm wheel 7 meshing therewith, until each clamping jaw 8 is tightly pressed against the surface of the mechanical workpiece, so that the mechanical workpiece can be firmly clamped;

[0039] Finally, when it is necessary to clamp a workpiece that is difficult to clamp, the first motor 11 can be controlled to drive in reverse so that each clamping jaw 8 rotates in opposite directions until it remains parallel to the hollow disk 5, and finally the suction cup 14 is pressed against the surface of the mechanical workpiece through the adjustable robot arm 4, and then the suction pump 13 is started to extract the air in the suction cup 14, so that the negative pressure generated at each negative pressure adsorption hole 15 can be used to complete the adsorption and clamping of the mechanical workpiece, thereby improving the versatility of the device.

[0040] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
