[0035] The mounting plate and the sleeve are fixedly connected by the connecting piece passing through the connecting hole, and the notch groove and the second mounting hole together form a connecting hole, so that when the connecting piece connects the mounting plate and the sleeve, the clamping cylinder can also be limited and fixed, thereby avoiding the situation where the clamping cylinder rotates due to the rotation of the cover plate, causing friction between the clamping cylinder and the moving block, reducing the wear between the components, and being conducive to extending the overall service life;

[0036] A plurality of accommodating grooves 603 are provided along the circumferential side wall of the locking cylinder 6, and the accommodating grooves 603 connect the inner wall and the outer wall of the locking cylinder 6, and a ball 601 is movably connected inside the accommodating grooves 603; a driving mechanism 3 for driving the moving block 4 to move is provided at the other end of the sleeve 6, and when the driving mechanism 3 pushes the moving block 4 to move along the outer wall of the locking cylinder 6, the ball 601 is exposed from the accommodating grooves 603, and an annular locking portion is formed on the inner wall of the locking cylinder 6, thereby realizing the picking up of the cover plate, avoiding the deformation of the cover plate caused by uneven force during the flipping process, and reducing the safety risk.

[0037] The notch grooves 10 are arranged at equal intervals along the circumferential direction of the engaging tube 6 .

[0038] There are two notch grooves 10 .

[0039] The connecting member 12 is a screw.

[0040] An annular inclined surface 602 is disposed at one end of the locking tube 6 close to the moving block 4 and along its circumference.

[0046] The working principle is:

[0047] When in use, the clamping cylinder is installed in the mounting hole of the sleeve, and the clamping cylinder is rotated so that the notch groove of the clamping cylinder and the second mounting hole of the mounting plate are closed, so that the notch groove and the second mounting hole form a connecting hole capable of accommodating the connecting member, and then the connecting member is inserted into the connecting hole, thereby realizing the fixed connection between the clamping cylinder, the sleeve and the mounting plate;

[0048] The sleeve is moved to make the positioning post embedded in the clamping tube. At this time, the driving mechanism drives the moving block away from the clamping tube, and the ball can move in the receiving groove. When the positioning post is embedded in the clamping tube, the upper end of the positioning post squeezes the ball, so that the ball is retracted into the receiving groove.

[0049] When the locking cylinder and the positioning column are engaged, the moving block pushes the ball out of the accommodating groove, so that the ball and the positioning column push and contact, so that the locking cylinder and the positioning column are fixed, so that the cover plate can be clamped and moved. When it moves to the specified position, the locking cylinder and the positioning column are separated, and the moving block moves away from the locking cylinder. Through the gravity of the cover plate, the positioning column can be separated from the locking cylinder, thereby separating the cover plate from the locking cylinder.

[0050] When the above-mentioned workpiece clamping and lifting device is used, it realizes the picking up of the cover plate, avoids the deformation of the cover plate caused by uneven force during the flipping process, and reduces the safety risk; further, it fixes the mounting plate and the sleeve through the connecting member passing through the connecting hole, and the notch groove and the second mounting hole together form a connecting hole, so that the connecting member can also limit and fix the locking cylinder when connecting the mounting plate and the sleeve, avoiding the situation where the rotation of the cover plate drives the rotation of the locking cylinder and causes friction between the locking cylinder and the moving block, reduces the wear between the components, and is conducive to extending the overall service life.
