DETAILED DESCRIPTION

[0036] Please refer to the instruction manual Figure 1-8 The present invention provides a technical solution: a multiple-stroke driving device, comprising: a base plate 1, a basic slide plate 2 is slidably arranged on the base plate 1, and a double-stroke slide plate 5 is slidably arranged on the basic slide plate 2; pulleys 6 are arranged at the four corners of the upper surface of the basic slide plate 2, and a transmission sleeve is provided with a belt 7 between the two corresponding pulleys 6; a first belt clamp plate 3 and a second belt clamp plate 4 are also arranged on the basic slide plate 2, and the first belt clamp plate 3 and the second belt clamp plate 4 are both rectangular frame structures, the first belt clamp plate 3 is fixedly connected to the upper surface of the basic slide plate 2, and the belt 7 moves through the middle of the first belt clamp plate 3, the second belt clamp plate 4 is fixedly connected to the side of the double-stroke slide plate 5, and the belt 7 is fixedly connected to the middle of the second belt clamp plate 4; pulleys 6 are also arranged in the middle of both ends of the double-stroke slide plate 5, and the double-stroke The two pulleys 6 at both ends of the skateboard 5 are also connected by a belt 7 transmission. The surface of the belt 7 above the double-stroke skateboard 5 is fixedly connected to a fixed base plate 12, and the end of the fixed base plate 12 is fixedly connected to a spare double-stroke skateboard 8. When working, the basic skateboard 2 slides along the length direction of the base plate 1 to increase the stroke by one level; the double-stroke skateboard 5 slides along the length direction of the basic skateboard 2 to increase the stroke by another level; the spare double-stroke skateboard 8 slides along the length direction of the double-stroke skateboard 5 to continue to increase the stroke by one level. The spare double-stroke skateboards 8 can be stacked, and the total stroke will be doubled for each additional spare double-stroke skateboard 8. Compared with equipment using a multi-stroke cantilever mechanism, the occupied space is significantly reduced, the rigidity of the moving parts is improved, the operating speed is increased, the movement time is effectively reduced, and the production efficiency is improved.

[0037] In the present invention, the pulley 6 and the belt 7 are used to cooperate to realize the movement of the double-range slide plate 5 and the spare double-range slide plate 8, which can greatly reduce the length of the overall device during extension and retraction, has a great advantage in occupying space, and at the same time reduces the problem of cantilever end shaking during the cantilever length movement process, thereby improving the operating stability.

[0038] In the present invention, a gear 10 is arranged on the upper surface of the substrate 1, and the basic skateboard 2 is a rectangular frame structure. A rack 11 is fixedly arranged on the inner wall of the side of the rectangular frame structure, and the rack 11 is engaged with the gear 10. A motor for driving the gear 10 to rotate is arranged on the bottom surface of the basic skateboard 2. When the motor is started, it drives the gear 10 to rotate. Since the gear 10 is engaged with the rack 11, the rack 11 will rotate synchronously, so that the basic skateboard 2 moves along the length direction of the substrate 1 to achieve the driving purpose.

[0039] It should be noted that the pulley 6 is equipped with a motor, which is not shown in the figure. When the motor drives the pulley 6 to rotate, the belt 7 is transmitted. When the belt 7 is transmitted, the double-range skateboard 5 moves relative to the basic skateboard 2, and the spare double-range skateboard 8 moves relative to the double-range skateboard 5.

[0040] In the present invention, each newly added spare double-range skateboard 8 is arranged in the direction between the basic skateboard 2 and the double-range skateboard 5. The belt 7 on the basic skateboard 2 is arranged on both sides, and the belt 7 on the double-range skateboard 5 is arranged in the middle. This can make full use of the plane space, make the overall device not thick, increase stability, and the overall device size is small.

[0041] In order to solve the shaking problem, the double-range skateboard 5 is configured as a rectangular frame structure in the present invention, and a magnetic plate 13 is fixedly provided on the inner wall of the double-range skateboard 5. The magnetic plate 13 and the fixed base plate 12 are attracted and fixed to each other, and the magnetic plate 13 is located on the inner side of the belt 7 on the double-range skateboard 5; when the spare double-range skateboard 8 moves to the end of the double-range skateboard 5, the fixed base plate 12 can be adsorbed and fixed by the magnetic plate 13, thereby increasing the stability of the spare double-range skateboard 8.

[0042] If the fixed base plate 12 is fixed by adsorbing the magnetic plate 13 alone, the friction coefficient between the magnetic plate 13 and the belt 7 will be too large, making it difficult for the spare double-range slide plate 8 to return. Therefore, an upper plate body 14 is fixedly provided on the upper surface of the magnetic plate 13, and a rolling groove 19 is provided on the upper surface of the upper plate body 14. A roller needle 17 is rotatably provided in the rolling groove 19. The roller needle 17 is movably fitted on the inner wall above the belt 7. There are multiple rolling grooves 19, and the multiple rolling grooves 19 are equidistantly distributed. Although the fixed base plate 12 is tightly fitted to the upper surface of the belt 7, due to the setting of the roller needle 17, the friction coefficient of the belt 7 relative to the magnetic plate 13 as a whole becomes smaller, and the overall device can still slide smoothly and remain smooth, so that the spare double-range slide plate 8 can return smoothly.

[0043] Furthermore, an oil chamber 15 for storing lubricating oil is provided inside the magnetic plate 13, a connecting groove 20 is provided at the bottom of the rolling groove 19, the lower end of the connecting groove 20 passes through and is connected to the oil chamber 15, a cotton column 18 is provided in the connecting groove 20, the upper end of the cotton column 18 is movably fitted with the bottom surface of the corresponding needle roller 17, and the lower end of the cotton column 18 is fitted on the lower inner wall of the oil chamber 15; when the belt 7 is being transmitted, the inner side surface of the belt 7 passes through the needle roller 17 to rotate the needle roller 17, and during the rotation of the needle roller 17, the lubricating oil drawn from the connecting groove 20 can be smeared on the inner wall of the belt 7, so that the friction coefficient between the pulley 6 and the belt 7 is reduced, the sliding is smooth, and the smoothness of the relative movement between the needle roller 17 and the inner wall of the belt 7 can be further increased.

[0044] During specific use, a refueling pipe 16 is provided on the side of the magnetic plate 13, and the lubricating oil is transported to the oil chamber 15 through the refueling pipe 16. The lubricating oil is absorbed by the connecting groove 20 and acts on the surface of the needle roller 17, which also reduces the wear of the needle roller 17 and increases the service life of the overall device.

[0045] Furthermore, in another embodiment, an arc groove 21 is provided on one side of the rolling groove 19 relative to the forward direction of the fixed base plate 12; a channel connected to the bottom of the arc groove 21 is reserved between the cotton column 18 and the inner wall of the connecting groove 20, and an arc baffle 22 is rotatably provided at the bottom of the arc groove 21, the arc opening of the arc baffle 22 faces the arc groove 21, one end of the arc baffle 22 is rotatably connected to the inner wall of the arc groove 21, and the other end of the arc baffle 22 is movably fitted on the surface of the needle roller 17; when the standby double-range slide plate 8 moves forward relative to the double-range slide plate 5, The needle roller 17 rotates clockwise, and the lubricating oil drawn from the connecting groove 20 is smeared on the inner wall of the belt 7 when the needle roller 17 rotates clockwise. Due to the setting of the magnetic plate 13, the iron particles or powder mixed in the lubricating oil will be adsorbed on the surface of the needle roller 17. As the needle roller 17 rotates, the iron particles or powder enter from the arc groove 21. When the iron particles or powder hit the arc baffle 22, the arc baffle 22 rotates downward, and the iron particles or powder are scraped off in the gap between the connecting groove 20 and the cotton column 18, and finally fall into the oil chamber 15.

[0046] When the spare double-range slide plate 8 moves backward relative to the double-range slide plate 5, the needle roller 17 rotates counterclockwise. During the counterclockwise rotation, the lubricating oil is normally applied to the inner wall of the belt 7. Since the arc-shaped baffle plate 22 can only rotate downward, it will prevent the iron particles or powder from flowing back into the connecting groove 20 or the oil chamber 15.

[0047] Therefore, the present invention can not only lubricate the inner wall of the belt 7 in real time, but also remove some iron particles or powder mixed in the lubricating oil, thereby improving the use effect and service life of the lubricating oil; it is particularly suitable for use in scenarios where iron particles or powder are easily generated due to relative wear between the belt 7 and the pulley 6.

[0048] In actual use, the base plate 1 is fixedly connected to the robot beam 9 for use, which is convenient and practical.
