[0002] The gripper cylinder is divided into three-jaw or four-jaw cylinders. Under the action of the cylinder, the workpiece or product is quantitatively fed within the working range. The feeding process is the continuous centripetal motion of the cylinder's grippers, which continuously pushes the item in one direction to complete the feeding.

The hydraulic buffer is installed on the three-jaw cylinder body, and the machine base connecting plate is connected to the three-jaw cylinder body. A fine-tuning mechanism is provided on the three-jaw cylinder body, and a rotating rod is connected within the fine-tuning mechanism. The rotary cylinder is located on the three-jaw cylinder body, and a drive shaft is installed within the rotary cylinder. The connecting bracket is connected to the drive shaft. This invention effectively extends the service life of the entire cylinder by installing a hydraulic buffer on the three-jaw cylinder body to release and alleviate pressure on the rotary cylinder.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a clamping mechanism, the clamping mechanism comprising: a mounting plate 1, a moving groove 2 provided on the side of the mounting plate 1, a support rod 3 provided in the moving groove 2, and a positioning tube 4 sleeved on the surface of the support rod 3;

[0024] Positioning block 5, the bottom plate of positioning block 5 is provided with an arc plate 6, the side of the arc plate 6 is provided with an auxiliary plate 7, the surface of the auxiliary plate 7 is provided with an arc groove 8, the surface of positioning block 5 is provided with a limit groove 9, and the surface of positioning block 5 is provided with a first bearing 10. A fully automatic press-fitting and feeding device includes the clamping mechanism described above.

[0025] Firstly, the arc plate 6, in conjunction with the auxiliary plate 7, can be used to conveniently position and clamp arc-shaped or square workpieces, thus facilitating stable clamping and feeding of the workpieces. When it is necessary to clamp a sphere, the arc groove 8 opened on the surface of the auxiliary plate 7 can be used to clamp the sphere, thus facilitating the clamping and feeding of spherical workpieces.

[0026] Example 2: Based on Example 1, in order to facilitate the clamping and feeding of workpieces of various shapes with the gripper cylinder, an arc plate 6 and an auxiliary plate 7 are provided. The auxiliary plate 7 is a square plate structure. Damping strips 11 are provided on the surface of the auxiliary plate 7. Multiple sets of damping strips 11 are provided and are arranged linearly at equal intervals about the auxiliary plate 7. The arc plate 6 is fixedly connected to the bottom of the positioning block 5. Damping pads 12 are provided on the inner side of the arc plate 6 and are glued to the inner side of the arc plate 6.

[0027] When in use, the arc plate 6 can be used to easily clamp and position the arc structure. When it is necessary to feed spherical or square workpieces, the positioning block 5 can be rotated, and then the auxiliary plate 7 and the arc groove 8 opened on the surface of the auxiliary plate 7 can be used to clamp and feed the square or spherical workpieces. The damping pad 12 and the damping strip 11 can increase the friction of clamping and increase the stability of clamping and feeding.

[0028] Example 3: Based on Example 2, a positioning tube 4 is provided to facilitate the rotation and fixation of the positioning block 5. The first bearing 10 is fixedly connected to the surface of the positioning block 5. A fixing rod 13 is fixedly connected to the inner ring surface of the first bearing 10. The mounting plate 1 is fixedly connected to the end face of the fixing rod 13. Two sets of moving grooves 2 are provided, and the two sets of moving grooves 2 are symmetrically distributed about the mounting plate 1. A threaded groove 14 is provided on the end face of the moving groove 2. A threaded rod 15 is screwed into the threaded groove 14. A limit nut 16 is provided on the surface of the threaded rod 15. A support rod 3 is fixedly connected to the surface of the limit nut 16. A limit spring 17 is sleeved on the surface of the support rod 3. One end of the limit spring 17 is fixedly connected to the end face of the positioning tube 4, and the other end of the limit spring 17 is fixedly connected to the surface of the limit nut 16. A pull plate 18 is provided on the side of the positioning tube 4. One end of the positioning tube 4 can be inserted into the limit groove 9.

[0029] When it is necessary to rotate the positioning block 5 during use, the positioning tube 4 can be pulled upward by the pull plate 18, so that one end of the positioning tube 4 can be disengaged from the limiting groove 9. Then the positioning block 5 can rotate in conjunction with the first bearing 10. After rotation, the positioning tube 4 can continue to be inserted into the limiting groove 9 for fixation. The setting of the limiting spring 17 also avoids the problem of arbitrary displacement of the positioning tube 4. In addition, the threaded rod 15 is screwed into the threaded groove 14, and the threaded rod 15 can be easily disengaged from the threaded groove 14 by rotating the limiting nut 16, so that the support rod 3 can be easily removed. Rotating the threaded rod 15 allows the pull plate 18 to rotate in the moving groove 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
