Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a synchronous transmission device and a punching machine. Background Art

[0002] A punching machine is a device that punches a sheet material into a predetermined shape. It consists of a blanking device and a feeding device. The feeding device continuously supplies the sheet material to the blanking device for the blanking device to punch the sheet material, thereby realizing the continuous processing of the sheet material. In the traditional technology, the feeding device and the blanking device are respectively driven to operate by different driving mechanisms. That is, an independent driving mechanism is required to drive the feeding device to swing to realize the continuous feeding of the feeding device, and an independent driving mechanism is required to drive the blanking device to rotate to realize the continuous blanking of the blanking device. However, when adjusting the production rhythm of the punching machine by using different driving mechanisms to drive the feeding device and the blanking device to operate independently, it is necessary to separately debug the swing frequency of the feeding device and the speed of the blanking device to keep the feeding speed and the blanking speed consistent, which increases the debugging time and difficulty of the production rhythm and has the technical problem of relatively high debugging cost of the production rhythm. Summary of the Utility Model

[0003] Based on this, in view of the technical problem of relatively high debugging cost of the production rhythm, it is necessary to provide a synchronous transmission device and a punching machine.

[0004] A synchronous transmission device is used to convert a rotational motion into a swinging motion. The synchronous transmission device includes: a rotating shaft, a rotating arm, a transmission rod, a swinging arm, and a swinging shaft that are connected in sequence. The rotating arm has a connection point and a rotation point, and the connection point and the rotation point are arranged at intervals. The rotating arm is fixedly connected to the rotating shaft corresponding to the connection point, and the rotating arm is rotatably connected to the transmission rod corresponding to the rotation point. The swinging arm has a swinging point and a transmission point, and the swinging point and the transmission point are arranged at intervals. The swinging arm is rotatably connected to the transmission rod corresponding to the swinging point, and the swinging arm is fixedly connected to the swinging shaft corresponding to the transmission point.

[0005] For the above-mentioned synchronous transmission device, when the rotating shaft is controlled to rotate, the rotating shaft drives the rotation point of the rotating arm to rotate around the connection point. The transmission rod connecting the connection point of the rotating arm drives the swing arm to actuate. Under the traction of the transmission rod, the swing arm causes the swing point connecting the transmission rod to reciprocally swing around the transmission point, thereby realizing the control of the swing shaft connecting the swing point of the swing arm to perform a reciprocating rotational motion, so as to convert the rotational motion of the rotating shaft into the swing motion of the swing shaft. Through the above design, with the cooperation of the rotating shaft, rotating arm, transmission rod, swing arm and swing shaft, it is beneficial to control the reciprocating swing frequency of the swing shaft by controlling the rotation speed of the rotating shaft. That is, by separately controlling the rotation speed of the rotating shaft, the swing frequency of the swing shaft can be synchronously controlled to maintain the synchronization of the rotation speed and swing frequency, thereby effectively reducing the debugging time and difficulty of the production beat and achieving the purpose of reducing the debugging cost of the production beat.

[0006] In one embodiment, the rotating arm includes a rotating seat and a rotating block. The rotating seat has the connection point and is fixedly connected to the rotating shaft. The rotating block has the rotation point and is slidably connected to the rotating seat.

The adjusting rod is provided with an external thread, and the rotating block is provided with an adjusting hole for the adjusting rod to pass through. The inner wall of the adjusting hole is provided with an internal thread that cooperates with the external thread.

[0009] In one embodiment, the rotating seat is further provided with a scale mark, and the scale mark is arranged along the sliding direction of the rotating block.

[0010] In one embodiment, the rotating arm further includes a pointer. The pointer is connected to the rotating block and is correspondingly arranged with the scale mark.

[0011] In one embodiment, the transmission rod includes a rod body and a ball eye block. The rod body is provided with a spherical groove, and the ball eye block is movably arranged in the spherical groove and is rotatably connected to the rotating arm.

[0012] In one embodiment, the swing arm includes a swing seat, a fine-tuning assembly and an adapter. The swing seat has the transmission point. The fine-tuning assembly is rotatably installed on the swing seat and is spaced from the transmission point. The fine-tuning assembly is provided with an eccentric hole, and the swing point is correspondingly arranged with the eccentric hole. The adapter is rotatably installed on the eccentric hole and is connected to the transmission rod.

[0013] In one embodiment, the fine-tuning component includes an adjusting sleeve and an adjusting driving member. The adjusting sleeve is rotatably connected to the swing seat and is provided with an eccentric hole, and the adjusting driving member drives the adjusting sleeve to rotate.

[0014] A punching machine includes the synchronous transmission device according to any one of the above, and further includes a blanking device and a feeding device. The blanking device is connected to the rotating shaft and drives the rotating shaft to rotate. The feeding device is connected to the swing shaft. By adopting the above synchronous transmission device, it is beneficial to reduce the debugging time and difficulty of the production rhythm of the punching machine, and achieve the purpose of reducing the debugging cost of the punching machine.

[0036] Below, in combination with Figures 1 to 4 , the above-mentioned synchronous transmission device 100 will be further described.

[0037] As Figures 1 to 2As shown, the rotating arm 20 includes a rotating base 21 and a rotating block 22. The rotating base 21 has the connection point 211 and is fixedly connected to the rotating shaft 10. The rotating block 22 has the rotation point 221 and is rotatably connected to the transmission rod 30. The rotating block 22 is slidably connected to the rotating base 21. Among them, the connection point 211 and the rotation point 221 are arranged at intervals. The rotating base 21 is provided with a limiting groove 212, and the cross-section of the limiting groove 212 is arranged in a T shape. The rotating block 22 is slidably arranged in the limiting groove 212. By controlling the position of the rotating block 22 on the rotating base 21, the distance between the connection point 211 and the rotation point 221 is realized, so as to achieve the purpose of controlling the swing amplitude of the swing shaft 50.

[0038] In order to improve the control accuracy of the swing amplitude of the swing shaft 50, as Figure 2 shown, the rotating arm 20 further includes an adjusting rod 23. The adjusting rod 23 is rotatably installed on the rotating base 21. The adjusting rod 23 is provided with an external thread. The rotating block 22 is provided with an adjusting hole (not shown in the figure) for the adjusting rod 23 to pass through. The inner wall of the adjusting hole is provided with an internal thread that cooperates with the external thread. By rotating the adjusting rod 23, it is beneficial to accurately control the moving accuracy of the rotating block 22, so as to achieve the purpose of improving the control accuracy of the swing amplitude of the swing shaft 50.

[0039] In order to accurately control the swing amplitude of the swing shaft 50, as Figure 2 shown, the rotating base 21 is further provided with a scale mark 24. The scale mark 24 is arranged along the sliding direction of the rotating block 22. The rotating arm 20 further includes a pointer 25. The pointer 25 is connected to the rotating block 22 and is arranged corresponding to the scale mark 24. Through the cooperation of the pointer 25 and the scale mark 24, it is beneficial to measure the position of the rotating block 22 relative to the rotating base 21, so as to achieve the purpose of accurately controlling the swing amplitude of the swing shaft 50.

[0040] As Figure 3 shown, the transmission rod 30 includes a rod body 31 and a ball eye block 32. The rod body 31 is provided with a spherical groove (not shown in the figure). The ball eye block 32 is movably arranged in the spherical groove and is rotatably connected to the rotating arm 20.

[0041] As Figure 1 and Figure 4As shown, the swing arm 40 includes a swing seat 41, a fine-tuning component 42 and an adapter 43. The swing seat 41 has the transmission point 411. The fine-tuning component 42 is rotatably mounted on the swing seat 41 and is spaced apart from the transmission point 411. The fine-tuning component 42 is provided with an eccentric hole 421. The eccentric hole 421 is the swing point 422. The swing point 422 is spaced apart from the transmission point 411. The adapter 43 is rotatably mounted on the eccentric hole 421 and is connected to the transmission rod 30. By controlling the rotation of the fine-tuning component 42, the distance between the eccentric hole 421 and the transmission point 411 can be controlled, thereby achieving fine control of the swing amplitude of the swing shaft 50.

[0042] In order to improve the control convenience of finely controlling the swing amplitude of the swing shaft 50, as Figure 4 As shown, the fine-tuning component 42 includes an adjusting sleeve 423 and an adjusting driving member 424. The adjusting sleeve 423 is rotatably connected to the swing seat 41 and is provided with an eccentric hole 421. The adjusting driving member 424 drives the adjusting sleeve 423 to rotate. Specifically, the adjusting driving member 424 is a motor, and controls the rotation of the adjusting sleeve 423 through a transmission belt. By controlling the rotation of the adjusting sleeve 423 through the adjusting driving member 424, it is beneficial to realize automatic control of the distance between the transmission point 411 and the swing point 422, so as to achieve the purpose of improving the control convenience of finely controlling the swing amplitude of the swing shaft 50.

[0043] The working principle of the synchronous transmission device 100 described in the utility model is: when the rotating shaft 10 is controlled to rotate, the rotating shaft 10 drives the rotating point 221 of the rotating arm 20 to rotate around the connection point 211, and the swing arm 40 is driven to actuate by the transmission rod 30 connected to the connection point 211 of the rotating arm 20. Under the traction of the transmission rod 30, the swing arm 40 makes the swing point 422 connected to the transmission rod 30 swing back and forth around the transmission point 411, thereby controlling the swing shaft 50 connected to the swing point 422 of the swing arm 40 to make reciprocating rotational motion, so as to realize the conversion of the rotational motion of the rotating shaft 10 into the swinging motion of the swing shaft 50.

[0044] The beneficial effects of the synchronous transmission device 100 described in the utility model are: the cooperation of the rotating shaft 10, the rotating arm 20, the transmission rod 30, the swing arm 40 and the swing shaft 50 is advantageous in that the reciprocating swing frequency of the swing shaft 50 can be controlled by controlling the rotation speed of the rotating shaft 10, that is, the swing frequency of the swing shaft 50 can be synchronously controlled by controlling the rotation speed of the rotating shaft 10 alone, so as to keep the rotation speed and the swing frequency synchronized, thereby effectively reducing the debugging time and difficulty of the production rhythm, and achieving the purpose of reducing the debugging cost of the production rhythm.

The blanking device 201 is connected to the rotating shaft 10 and drives the rotating shaft 10 to rotate. The feeding device 202 is connected to the swing shaft 50. By adopting the above synchronous transmission device 100, it is beneficial to reduce the debugging time and debugging difficulty of the production beat of the punching machine 200, and achieve the purpose of reducing the debugging cost of the punching machine 200.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0047] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
