Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and in particular, it designs a multi-station riveting turntable. Background Technology

[0002] Multi-station riveting turntables automate processes such as loading, riveting, inspection, and unloading through various tooling fixtures, significantly improving production efficiency. The double-layer turntable structure allows for more workstations without increasing the overall worktable size, achieving space-saving goals. There are both fixed, synchronously rotating double-layer turntables and independently rotating double-layer turntables. Synchronous rotation is suitable for a one-to-one arrangement of upper and lower turntable workstations. Independent rotation involves one turntable being fixed while the other rotates, suitable for a one-to-many arrangement of upper and lower turntable workstations. Currently, the independently driven double-layer turntables use two servo motors, which results in high manufacturing and maintenance costs due to the large number of servo motors required. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-station riveting turntable that uses an electromagnet to switch between the fixed and separated states of a double-layer turntable, thereby reducing the number of servo motors required.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a multi-station riveting turntable, comprising a worktable body, a servo motor, a telescopic cylinder, a lower turntable, an upper turntable, a T-shaped sleeve, and a linkage mechanism;

[0005] The linkage mechanism consists of a hollow rotating shaft, an electromagnet, an iron block, a first pin, and a connecting rod.

[0006] The servo motor is fixedly mounted on the main body of the worktable. The hollow rotating shaft is fixedly connected to the output shaft of the servo motor. The upper turntable is fixedly mounted on the top of the hollow rotating shaft. The electromagnet is fixedly mounted on the top of the inner hole of the hollow rotating shaft. The hollow rotating shaft is provided with a longitudinal slide groove that communicates with the inner hole of the hollow rotating shaft. The connecting rod is slidably mounted in the longitudinal slide groove. The first pin is fixedly mounted on the connecting rod. The iron block is located in the inner hole of the hollow rotating shaft and is fixedly connected to the connecting rod. A ball bearing is sleeved on the outer wall of the bottom of the hollow rotating shaft. The lower turntable is fixedly connected to the T-shaped sleeve. The T-shaped sleeve is fixedly sleeved on the cage of the ball bearing. The T-shaped sleeve is provided with a limiting through hole that cooperates with the first pin.

[0007] The cylinder body of the telescopic cylinder is fixedly installed on the main body of the workbench. A second pin is provided on the top of the telescopic cylinder, and a stop blind hole that cooperates with the second pin is provided on the bottom surface of the lower turntable.

[0008] Preferably, a guide sleeve is fixedly installed on the bottom surface of the upper turntable, the upper end of the first pin is slidably installed in the guide sleeve, and a spring is sleeved on the first pin, with the upper and lower ends of the spring acting on the guide sleeve and the connecting rod respectively.

[0009] Preferably, the connecting rod is configured as a cross-shaped connecting rod structure.

[0010] Preferably, the outer ends of both the first pin and the second pin are rounded.

[0011] Preferably, a rubber sleeve is fixedly installed on the bottom surface of the connecting rod, and the rubber sleeve is sleeved on the first pin.

[0012] Compared with existing technologies, the advantages of this utility model are: this workbench, through the coordination of a servo motor and a linkage mechanism, automatically switches between the fixed and separated states of the lower and upper turntables. This allows the upper turntable to rotate independently, meeting the needs of a one-to-many setup with upper and lower turntables, or to rotate synchronously with the lower turntable, meeting the needs of a one-to-one setup with upper and lower turntables. A single servo motor is sufficient to drive the system, reducing the cost of using and maintaining the servo motor. Attached Figure Description

[0016] Figure 3 yes Figure 1 Enlarged structural diagram at point M. Detailed Implementation

[0017] The present invention will now be described in detail with reference to specific embodiments:

[0018] like Figures 1 to 3 The multi-station riveting turntable shown includes a worktable body 1, a servo motor 2, a telescopic cylinder 3, a lower turntable 4, an upper turntable 5, a T-shaped sleeve 41, and a linkage mechanism.

[0019] The linkage mechanism consists of a hollow rotating shaft 6, an electromagnet 61, an iron block 62, a first pin 7, and a connecting rod 8;

[0020] Servo motor 2 is fixedly installed on the main body 1 of the workbench. Hollow rotating shaft 6 is fixedly connected to the output shaft of servo motor 2. Upper turntable 5 is fixedly installed on the top of hollow rotating shaft 6. Electromagnet 61 is fixedly installed on the top of the inner hole of hollow rotating shaft 6. Longitudinal slide groove 60 connected to the inner hole of hollow rotating shaft 6 is provided on hollow rotating shaft 6. Connecting rod 8 is slidably installed in longitudinal slide groove 60. First pin 7 is fixedly installed on connecting rod 8. Iron block 62 is located in the inner hole of hollow rotating shaft 6 and is fixedly connected to connecting rod 8. Ball bearing is sleeved on the bottom outer wall of hollow rotating shaft 6, that is, the rotating body of ball bearing is fixedly sleeved on hollow rotating shaft 6. Lower turntable 4 is fixedly connected to T-shaped sleeve 41. T-shaped sleeve 41 is fixedly sleeved on the cage of ball bearing. T-shaped sleeve 41 is provided with a limiting through hole that cooperates with first pin 7.

[0021] The cylinder body of the telescopic cylinder 3 is fixedly installed on the main body 1 of the workbench via the cylinder seat 31. A second pin is provided on the top of the telescopic cylinder 3, and a stop blind hole that cooperates with the second pin is provided on the bottom surface of the lower turntable 4.

[0022] A guide sleeve 9 is fixedly installed on the bottom surface of the upper turntable 5. The upper end of the first pin 7 is slidably installed in the guide sleeve 9. A spring 71 is sleeved on the first pin 7. The upper and lower ends of the spring 71 act on the guide sleeve 9 and the connecting rod 8 respectively. The guide sleeve 9 can improve the straightness of the first pin 7 and the connecting rod 8 when they move up and down, and avoid the problem of jamming when moving up and down. The elastic force of the spring 71 acts on the connecting rod 8, which can prevent the first pin 7 from coming out of the limiting through hole due to the vibration of the worktable.

[0023] The connecting rod 8 is configured as a cross-link structure, that is, four first pins 7 are provided on the connecting rod 8, and four longitudinal sliding grooves 60 are arranged in a ring array on the hollow rotating shaft 6, which can improve the stability of the connecting rod 8 when it moves up and down.

[0024] The outer ends of the first pin 7 and the second pin are both set with rounded corners, which can improve the guiding effect for the first pin 7 and the second pin to slide into the limiting through hole and the stop blind hole respectively.

[0025] A rubber sleeve 81 is fixedly installed on the bottom surface of the connecting rod 8. The rubber sleeve 81 is sleeved on the first pin 7. When the connecting rod 8 moves downward, the rubber sleeve 81 contacts the T-shaped sleeve, which can avoid the noise generated by the rigid collision between the connecting rod 8 and the T-shaped sleeve.

[0026] When the lower turntable 4 needs to be fixed and the upper turntable 5 needs to rotate independently, the electromagnet 61 is energized and activated, attracting the combination of the iron block 62, connecting rod 8, and first pin 7 to move upward against gravity and the elastic force of spring 71. The lower end of the first pin 7 disengages from the limiting through hole of the T-shaped sleeve 41. At this time, the combination of the T-shaped sleeve 41 and the lower turntable 4 separates from the upper turntable 5. The servo motor 2 drives the hollow rotating shaft 6 and the upper turntable 5 to rotate independently. The piston rod of the telescopic cylinder 3 extends and pushes the top of the second pin to slide into the stop blind hole of the lower turntable 4 to restrict the lower turntable 4 from rotating freely around the ball bearing.

[0027] When the lower turntable 4 and the upper turntable 5 need to rotate synchronously, the electromagnet 61 is de-energized. The combination of the iron block 62, the connecting rod 8, and the first pin 7 moves downward under the action of gravity and the elastic force of the spring 71. The lower end of the first pin 7 slides into the limiting through hole of the T-shaped sleeve 41. At this time, the combination of the T-shaped sleeve 41 and the lower turntable 4 is fixed to the upper turntable 5. The servo motor 2 drives the hollow rotating shaft 6, the upper turntable 5, the linkage mechanism, and the lower turntable 4 to rotate independently. The piston rod of the telescopic cylinder 3 extends and drives the second pin to disengage from the stop blind hole of the lower turntable 4, thus removing the limiting effect on the lower turntable 4 and enabling it to rotate synchronously with the upper turntable 5.
