Modes for Carrying Out the Invention

[0008] Hereinafter, the present application will be described in more detail with reference to the drawings.

[0009] As shown in FIGS. 1 to 7, the present application discloses a quick-exchange device for a chuck of a vulcanizer PCI attached to a vulcanizer PCI stand 1. The quick-exchange device includes a chuck 2, a chuck base 3, and a pressing assembly. The chuck 2 is provided with a concave groove 11 and a first protrusion 12. The chuck 2 is detachably provided on the chuck base 3. The pressing assembly includes a rotating shaft 4 provided in the chuck base 3. A pressing plate 5 is connected to an end of the rotating shaft 4. The pressing plate 5 and the rotating shaft 4 are fixed by welding. The pressing plate 5 is provided with a second protrusion 51. The chuck 2 is provided between the chuck base 3 and the pressing plate 5.

[0010] The beneficial point of adopting the above technical solution is that the pressing plate 5 is provided to fix the chuck 2 to the chuck base 3, and the rotating shaft 4 is provided to move the pressing plate 5 to rotate. When the second protrusion 51 on the pressing plate 5 corresponds to the first protrusion 12 on the chuck 2, the pressing plate 5 presses the chuck 2 against the chuck base 3. After the pressing plate 5 rotates, the second protrusion 51 on the pressing plate 5 corresponds to the concave groove 11 on the chuck 2. At this time, the pressing plate 5 does not contact the chuck 2, and the chuck 2 can be directly removed without the need for manual removal, reducing the replacement time of the chuck 2. Compared with the connection method by screws, it reduces the damage to the chuck 2 during replacement and improves the processing efficiency of the equipment.

[0011] In some embodiments, as shown in FIG. 3, the pressing plate 5 is provided with a mounting groove 52 on a side surface contacting the chuck 2 of the pressing plate 5. A positioning pin 53 is provided in the mounting groove 52. A spring 54 is fitted on the positioning pin 53. An end of the positioning pin 53 protrudes from the mounting groove 52. The chuck 2 is provided with a positioning hole 22. A stopper piece is provided at a position of the positioning pin 53 close to the chuck 2. The stopper piece is fixedly connected to the tip of the positioning pin 53 and can move within the mounting groove 52. One end of the spring 54 abuts against the stopper piece. The above structural solution can be adopted.

[0012] The beneficial point of adopting the above technical solution is that when the pressing plate 5 is mounted on the chuck 2, the positioning pin 53 enters into the positioning hole 22, preventing the relative slide between the chuck 2 and the pressing plate 5, and with the installation of the spring 54, the movement of the positioning pin 53 becomes easier.

[0013] In some embodiments, the above-mentioned positioning hole 22 may adopt a structural solution that the side surface of the positioning hole 22 is a transition surface with an inclination, and the cross section of the end of the positioning pin 53 is semi-circular.

[0014] The beneficial point of adopting the above technical solution is that when removal is required, the pressing plate 5 is rotated. At this time, the positioning pin 53 moves along the transition surface of the positioning hole 22 to the surface of the chuck 2, completing the withdrawal operation of the positioning pin 53 from the positioning hole 22, and the top of the positioning pin 53 is smooth and will not be caught in the positioning hole 22.

[0015] In some embodiments, as shown in FIG. 4, the rotating shaft 4 is connected with a rotational drive assembly on the rotating shaft 4. The rotational drive assembly includes a drive cylinder 41 and a connecting rod 42. The connecting rod 42 and the rotating shaft 4 are fixedly connected by a screw. The cylinder block of the drive cylinder 41 is provided with a hinge connection to the vulcanizer PCI stand 1. The output end of the drive cylinder 41 is connected to the first end of the connecting rod 42. The second end of the connecting rod 42 is connected to the rotating shaft 4. A structural solution that the connecting rod 41 rotates around the rotating shaft 4 can be adopted.

[0016] The beneficial point of adopting the above technical solution is that the protruding end of the drive cylinder 41 is connected to the connecting rod 42 to move the connecting rod 42 to move, and then the connecting rod 42 drives the rotating shaft 4 to rotate, and further the rotating shaft 4 drives the pressing plate 5 to rotate, and the chuck 2 can be directly removed from the chuck base 3 without the need for manual removal.

[0017] In some embodiments, as shown in FIG. 2, the chuck base 3 may adopt a structural solution in which a chuck positioning pin 32 is provided on the chuck base 3, and a pin hole 21 is provided at a position corresponding to the chuck positioning pin 32 of the chuck 2.

[0018] The beneficial effect of adopting the above technical solution is that by providing the chuck positioning pin 32 on the chuck base 3 to be fitted into the pin hole 21 located on the chuck 2, it is possible to prevent the chuck 2 from rotating during use and affecting the processing of the product.

[0019] In some embodiments, the chuck 2 includes an upper chuck 23 and a lower chuck 24. The rotating shaft 4 includes an upper rotating shaft 43 and a lower rotating shaft 44. The upper rotating shaft 43 is provided inside the upper chuck 23, and the lower rotating shaft 44 is provided inside the lower chuck 24. Pressing plates 5 are respectively and fixedly provided on the upper rotating shaft 43 and the lower rotating shaft 44. The pressing plates 5 on the upper rotating shaft 43 and the lower rotating shaft 44 are provided in pairs to fix the upper chuck 23 and the lower chuck 24 provided in pairs. A locking head 45 is provided at the end of the lower rotating shaft 44, and a locking port 46 is provided on the upper rotating shaft 43. The locking head 45 and the locking port 46 are fitted together. A T-shaped protrusion protruding into the locking port 46 is provided at the end of the locking head 45, and a T-shaped groove is provided inside the locking port 46. When the locking head 45 enters the locking port 46, the cross-shaped protrusion and the cross-shaped groove are fitted together to realize the connection and synchronous rotation of the upper rotating shaft 43 and the lower rotating shaft 44. A structural solution can be adopted.

[0020] The beneficial effect of adopting the above technical solution is that when the locking head 45 and the locking port 46 are fitted together to connect and fix the upper rotating shaft 43 and the lower rotating shaft 44, and the upper rotating shaft 43 and the lower rotating shaft 44 rotate simultaneously under the drive of one driving cylinder 41, the upper chuck 23 and the lower chuck 24 can be removed, reducing the drive structure and lowering the processing cost.

[0021] In some embodiments, as shown in FIGS. 7 to 8, the chuck 2 may adopt a structural solution in which the inclination angle of the side surface of the pressing plate 5 of the chuck 2 that contacts the chuck 2 is the same as the inclination angle of the side surface of the pressing plate 5 that contacts the chuck 2.

[0022] The beneficial point of adopting the above technical solution is that by providing an inclined surface between the chuck 2 and the pressing plate 5, when the pressing plate 5 is moved and rotated by the rotating shaft 4, the two inclined surfaces come into contact, pressing the chuck 2 and preventing the rotation of the chuck 2, realizing the function of being pressed and self-locked, and avoiding the rotation of the chuck 2 during the processing process.

[0023] In some embodiments, the drive cylinder 41 may adopt a structural solution in which the drive cylinder 41 is provided horizontally.

[0024] The beneficial point of adopting the above technical solution is that the horizontally provided drive cylinder 41 drives one end of the connecting rod 42 to reciprocate horizontally, the rotating shaft 4 connected to the connecting rod 42 rotates, and further moves the pressing plate 5 to rotate.

[0025] During the working process, when the chuck 2 needs to be replaced, first, the upper chuck 23 is moved by the vulcanization equipment to contact the lower chuck 24. At this time, the lock head 45 on the lower rotating shaft 44 enters the lock port 46, and the drive cylinder 41 extends and moves the rotating shaft 4 to rotate. At this time, the pressing plate 5 rotates, and the second protrusion 51 on the pressing plate 5 rotates from the first protrusion 12 on the chuck 2 into the concave groove 11. In this case, the pressing plate 5 does not contact the chuck 2, and the chuck base 3 located above rises with the vulcanization equipment, takes out the chuck 2 from the upper chuck base 3 and the lower chuck base 3, and then replaces it with the replaced chuck 2. Then, the upper chuck base 3 descends with the vulcanization equipment, the drive cylinder 41 retracts, and the pressing plate 5 rotates reversely to press the chuck 2 again to complete the replacement.
