Description

Technical Field

[0001] The utility model relates to the field of synchronous wheel processing, in particular to a bearing platform for synchronous wheel processing. Background Art

[0002] A synchronous pulley is a transmission accessory that can mesh with a synchronous belt. It is mainly driven by the synchronous belt and is widely used in new mechanical belt drives in various industries such as automation equipment, machine tools, textiles, printing, food packaging, wires and cables, instruments and meters, petrochemicals, tobacco, and communications.

[0003] When the synchronous wheel is processed and produced, according to the processing needs, some of them need to be press-fitted with a baffle structure on one side or both sides. The synchronous wheel is mainly processed by a press-fitting machine when the baffle is pressed. When the synchronous wheel press-fitting bearing table is in use, it is located in the middle of the machine as a rotating table for placing the synchronous wheel and a pressing mechanism. After the synchronous wheel press-fitting is completed, the staff needs to first remove the pressed synchronous wheel and arrange it neatly, and then combine the synchronous wheel with the baffle and place it in the processing position. Such repeated processing operations result in a long interval between the two processing operations, affecting the overall processing efficiency. Utility Model Content

At the same time, only one of the four three-jaw clamps 6 is processing the synchronous wheel on the synchronous wheel placement seat 9. At this time, the staff can take out the synchronous wheels after processing the upper ends of the other three synchronous wheel placement seats 9 during the synchronous wheel pressing process, and put in the synchronous wheels to be pressed, thereby improving production and processing efficiency. The rotating drive shaft 10 can be controlled to rotate by a stepping motor in the prior art, and then the rotating drive shaft 10 can push the switching turntable 3 to rotate 90 degrees, so that the three-jaw clamp 6 is in the pressing position.

[0029] A driving groove is provided on one side of the control chamber 2, and a driving gear 8 is horizontally provided in the driving groove. The teeth on one side of the driving gear 8 are placed in the control chamber 2. When the three-jaw clamp 6 is located at the center of the processing carrier 1, the driven gear 7 at the lower end of the three-jaw clamp 6 is meshed and connected with one side of the driving gear 8. During the pressing process of the synchronous wheel baffle, the three-jaw clamp 6 needs to be rotated. When the three-jaw clamp 6 is rotated to the pressing station through the switching turntable 3, the driven gear 7 of the three-jaw clamp 6 is meshed with the driving gear 8 after the movement is completed. At this time, when the driving gear 8 is driven to rotate by the motor in the prior art, the three-jaw clamp 6 of the pressing operation rotates at high speed.

[0030] In this embodiment, the assembled synchronous wheels and baffles are placed in sequence above the synchronous wheel placement seats 9 of the four three-jaw clamps 6. When one of the three-jaw clamps 6 is rotated to the pressing station of the processing carrier 1 by the switching turntable 3 controlled by the rotating drive shaft 10, the driven gear 7 of the three-jaw clamp 6 is engaged with the driving gear 8. The driving gear 8 is driven by the motor to rotate and control the three-jaw clamp 6 and the synchronous wheel to rotate. At this time, the synchronous wheel baffle processing can be completed in conjunction with the pressing mechanism. When the processing is completed, the next three-jaw clamp 6 equipped with the synchronous wheel moves to the pressing work and performs continuous pressing operations. During this period, the upper synchronous wheels of the other three three-jaw clamps 6 can be removed and placed for pressing.

[0031] Embodiment 2, on the basis of embodiment 1, is provided with a positioning switch assembly to position the rotation fixed position of the switching turntable 3, the positioning switch assembly is movably arranged at the center of the operating surface of the processing carrier 1, the positioning switch assembly includes a pressing plate 13, a first switch 16 and a second switch 17, the operating surface of the processing carrier 1 is provided with a switch platform, the upper end of the switch platform is provided with a regulating groove 12, and a yield groove is inclined on one side of the lower end of the regulating groove 12, two rotating pins 14 are symmetrically provided on both sides of the pressing plate 13, and the two rotating pins 14 are respectively and horizontally movably plugged into the two sides of the regulating groove 12, and the pressing plate 13 is higher than the upper surface of the switching turntable 3;

A positioning slot 11 is provided on the upper end of the switching dial 3 close to the three-claw clamp 6. The lower end of the pressing plate 13 on one side of the switching dial 3 is provided with a positioning block 15. The lower end of the positioning block 15 is inserted into the positioning slot 11 on one side of the switching dial 3. When the positioning block 15 is inserted into the positioning slot 11, the lower end of the pressing plate 13 squeezes the upper end of the first switch 16. When the pressing plate 13 is in the When in a horizontal posture, the lower end of the positioning block 15 is inserted into the positioning slot 11. At this time, the switching turntable 3 is restricted in rotation by the positioning block 15, ensuring that the three-jaw clamp 6 is in an accurate press-fitting position. At this time, the pressing plate 13 is squeezed by the first switch 16. The first switch 16 controls the connection of the driving gear 8 to rotate through a wire or a wireless controller. At this time, the driving gear 8 controls the three-jaw clamp 6 to rotate. The time for a single rotation of the three-jaw clamp 6 is 5-10s, and the time setting can be programmed and controlled by the PLC.

The virtual axis of the arc-shaped guide rod 18 is coaxially arranged with the rotation pin 14. When the positioning block 15 is away from the positioning groove 11, the lower end of the pressing plate 13 squeezes the upper end of the second switch 17. When the three-claw clamp 6 completes a single rotation, the staff presses the pressing plate 13 to extend one side of the regulating groove 12. The regulating groove 12 rotates through the rotation pin 14 and the arc-shaped guide rod 18. At this time, the positioning block 15 moves out of the positioning groove 11, and the lower end of the pressing plate 13 is away from the first switch 1 6 and contacts and squeezes the second switch 17, and the rotating drive shaft 10 controls the switching dial 3 to rotate through the motor. At this time, the lower end of the positioning block 15 contacts the upper surface of the switching dial 3. After the operator releases his hand, the pressing plate 13 is still in contact with the second switch 17, and the switching dial 3 continues to rotate. When the positioning block 15 reaches the next positioning groove 11 position, that is, the position of the three-jaw clamp 6, the positioning block 15 descends along with the pressing plate 13 under the elastic action of the arc spring 19, and the positioning block 15 is inserted into the positioning groove 11. The second switch 17 is released, the switching dial 3 stops rotating, and the first switch 16 is started to control the rotation of the next three-jaw clamp 6.
