[0025] The outer edge of the top surface of the box base 3 can be detachably fixed to the outer edge of the bottom surface of the top plate 2, wherein the outer edge of the top plate 2 can be fixed to the outer edge of the top surface of the box base 3 by screws; the front and rear ends of the bottom of the inner cavity of the box base 3 are respectively provided with bottom slide grooves 3.2 along the horizontal direction, the front and rear walls of the inner cavity of the box base 3 are respectively provided with inner slide grooves 3.1 along the horizontal direction, and the bottoms of the front and rear walls of the box base 3 are respectively provided with outer slide grooves 3.3 along the horizontal direction.

[0026] The clamping plate 4 includes a pair of clamping plate bodies 4.1, the top ends of which are respectively slidably engaged with the bottom of the box base 3 in the transverse direction, and a plurality of threaded sleeves 4.4 fixedly sleeved on the outer side walls of the clamping plate bodies 4.1. Positions in the clamping plate bodies 4.1 corresponding to the threaded sleeves 4.4 are respectively provided with cylindrical cavities 4.1.2 in the transverse direction, and positions on the inner side walls of the clamping plate bodies 4.1 corresponding to the cylindrical cavities 4.1.2 are respectively provided with through holes 4.1.3. The elastic telescopic rod 5 includes an end bolt 5.1 threadedly sleeved with the threaded sleeve 4.4, a push rod 5.2 slidably sleeved with the through hole 4.1.3, a limit ring 5.4 slidably sleeved with the cylindrical cavity 4.1.2 and sleeved on the end of the push rod 5.2, and a spring 5.3 arranged in the cylindrical cavity 4.1.2. Among them, the top of the splint body 4.1 is integrally formed with an extension plate 4.2 at the position corresponding to the front and rear walls of the box base 3, and a slider 4.3 that is slidably engaged with the outer slide groove 3.3 is fixed to the position of the extension plate 4.2 close to the box base 3; the top surface of the splint body 4.1 is provided with a slot 4.1.1 at the position corresponding to the bottom slide groove 3.2.

[0027] The push drive mechanism 6 is arranged in the inner cavity of the box base 3 and is used to drive the two clamping plates 4.1 to open and close. The push drive mechanism 6 includes a gear 6.2 whose bottom end of the central axis is rotatably mounted on the middle part of the bottom surface of the inner cavity of the box base 3, two racks 6.1 that are slidably engaged with the front and rear walls of the inner cavity of the box base 3 and meshed with the front and rear ends of the gears 6.2, and a telescopic cylinder 6.3 that pushes and pulls one of the racks 6.1 to move horizontally. A vertical rod 6.1.2 that is slidably engaged with the bottom slide groove 3.2 is fixed to the outer end of the bottom surface of the rack 6.1, and the bottom end of the vertical rod 6.1.2 is plugged into the corresponding slot 4.1.1. Specifically, the rack 6.1 is provided with a slide rail 6.1.1 that is slidably engaged with the inner slide groove 3.1 to ensure the smooth sliding of the rack 6.1.

[0028] In summary, when clamping a workpiece, the manipulator drives the clamp as a whole to flexibly move to the workpiece through the connection seat 1 and the top plate 2, so that the workpiece is located between the two clamping plate bodies 4.1. The piston rod of the telescopic cylinder 6.3 pulls the front rack 6.1 inward through the connection plate 6.4, and the front rack 6.1 drives the gear 6.2 to rotate when it moves horizontally, thereby driving the rear rack 6.1 to move horizontally, that is, the two racks 6.1 drive the two clamping plate bodies 4.1 to move toward each other through the vertical rods 6.1.2, so as to realize the clamping operation of the workpiece.

[0029] As the two clamping plates 4.1 move toward the workpiece, the push rods 5.2 gradually come into contact with the workpiece. According to the concave and convex shape of the outer wall of the workpiece, the push rods 5.2 will correspondingly retract a certain length into the cylindrical cavity 4.1.2 through the limit ring 5.4 to compress the spring 5.3, so that multiple push rods 5.2 can be pressed tightly against the outer wall of the workpiece to achieve the effect of effectively clamping workpieces of different shapes and sizes.
