Description

Technical Field

[0001] This utility model belongs to the technical field of brush table technology and relates to a brush table telescopic mechanism. Background Technology

[0002] In the sheet metal processing industry, brush tables can prevent sheet metal from being scratched, slipping, or falling during processing. For example, on equipment such as CNC punching machines, brush tables serve as supporting transmission components, preventing direct friction and collisions between the workpiece and the equipment, thus ensuring processing quality.

[0003] The existing brush table structure, when the brush table moves back and forth, such as when the brush table moves to the front position, is prone to serious sag of the frame due to the weight of the table itself, which will cause the movement to be unsmooth, the mechanism to jam, and affect the use. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing brush table structures, when the brush table moves back and forth, such as when the brush table moves to the front position, the frame is prone to serious sag due to the weight of the table itself, which will cause the movement to be unsmooth, the mechanism to jam, and affect the use.

[0005] The present invention discloses a telescopic mechanism for a brush table, comprising a connecting column, with a receiving frame installed at each end of the connecting column, a mounting plate fixedly connected to the end of the receiving frame near the connecting column, and a mounting frame provided at the end of the receiving frame away from the mounting plate, with a receiving plate installed on the mounting frame, and multiple sets of brush plates installed on the receiving plate.

[0006] A telescopic assembly is disposed at the end of the receiving frame away from the mounting plate, and the telescopic assembly is used in conjunction with the mounting frame;

[0007] A flipping assembly is disposed at one end of the mounting bracket, and the flipping assembly is used in conjunction with the receiving plate;

[0008] A cleaning component is disposed on the bottom side of the receiving frame, and the cleaning component is used in conjunction with the flipping component.

[0009] The telescopic assembly includes a first guide shoe and a second guide shoe. The first guide shoe is installed at the end of the receiving frame away from the mounting plate. The first guide shoe is slidably connected to a first guide rail. A second guide rail is installed on one side of the first guide rail. The second guide shoe is installed on one side of the mounting frame. The second guide shoe and the second guide rail are slidably connected.

[0010] The flipping assembly includes a mounting frame with a connecting frame and an adjusting motor mounted on one end. Both the connecting frame and the adjusting motor are mounted on one end of the mounting frame. A rotating rod passes through the inside of the connecting frame. A connecting plate is connected to one end of the rotating rod inside the connecting frame. One end of the connecting plate is connected to a receiving plate. A pulley assembly is provided between the output end of the adjusting motor and the rotating rod.

[0011] The cleaning component includes a support frame, which is installed on one side of the receiving frame. A servo motor is installed on one side of the middle of the support frame. A lead screw connected to the output end of the servo motor is rotatably passed through the middle of the support frame. A slide plate is connected to the lead screw and nut pair. A scraper is installed on one side of the slide plate.

[0012] The cleaning assembly further includes a transmission rack, a first connecting frame, and a second connecting frame. The transmission rack is installed at both ends of the support frame. The first and second connecting frames are both installed at both ends of the slide plate. A first transmission rod is rotatably passed through one end of the first connecting frame, and a second transmission rod is rotatably connected to one end of the second connecting frame. A bevel gear set is configured to drive between the first and second transmission rods.

[0013] The cleaning assembly also includes an air delivery frame, which is mounted on one side of the slide plate. Multiple sets of nozzles are connected to the air delivery frame, and an air delivery pipe is connected inside one side of the air delivery frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by redesigning the existing guide rail structure through the telescopic component, the original single guide rails on both sides are changed to a multi-segment telescopic guide rail composed of a first guide rail, a first guide rail, and an mounting frame. That is, when the receiving plate needs to move away from the receiving frame, the receiving plate drives the multi-segment telescopic guide rail to extend outward synchronously, providing sufficient strength and deflection to ensure that the side of the receiving plate away from the brush plate has a sufficiently long guide rail to provide support, thereby achieving the effect of keeping the receiving plate in a horizontal state. This ensures that the horizontal height error of the receiving plate can always be kept within the allowable range, thus ensuring that the expected functional effect is achieved.

[0015] By combining scraping, tapping, and airflow to automatically clean the surface of the flipped brush plate, impurities and dust on the brush table are cleaned more thoroughly, and manual intervention is reduced during the cleaning process. Attached Figure Description

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] like Figures 1-6 As shown, a brush table telescopic mechanism includes a connecting column 1, with receiving frames 2 installed at both ends of the connecting column 1. The connecting column 1 and the receiving frames 2 form the basic receiving frame of the device. A mounting plate 3 is fixedly connected to the end of the receiving frame 2 near the connecting column 1 for mounting the device to an external frame using bolts or other fasteners. A mounting frame 4 is provided at the end of the receiving frame 2 away from the mounting plate 3 for receiving. A receiving plate 5 is installed on the mounting frame 4, and multiple sets of brush plates 6 are installed on the receiving plate 5 for cleaning, deburring, or other treatment operations on the workpiece.

[0030] The telescopic component is located at the end of the receiving frame 2 away from the mounting plate 3, and is used in conjunction with the mounting frame 4.

[0031] The flipping component is located at one end of the mounting bracket 4 and is used in conjunction with the receiving plate 5.

[0032] The cleaning component is located on the bottom side of the receiving frame 2 and is used in conjunction with the flipping component.

[0033] Example 2

[0034] like Figures 1-6 As shown, the telescopic assembly includes a first guide shoe 7 and a second guide shoe 10. The first guide shoe 7 is installed at the end of the receiving frame 2 away from the mounting plate 3. The first guide shoe 7 is slidably connected to a first guide rail 8. A second guide rail 9 is installed on one side of the first guide rail 8. The second guide shoe 10 is installed on one side of the mounting frame 4. The second guide shoe 10 and the second guide rail 9 are slidably connected.

[0035] During operation, the mounting plate 3 is installed to the external frame using bolts and other fasteners. In use, the first guide rail 8 can slide on the receiving frame 2 via the first guide shoe 7, while the mounting frame 4 can slide on the second guide rail 9 via the second guide shoe 10. The first guide rail 8 and the second guide rail 9 are also connected in the same way, allowing the second guide rail 9 to slide on the first guide rail 8. In summary, the telescopic assembly redesigns the existing guide rail structure, changing the original single guide rails on both sides to a multi-segment telescopic guide rail composed of the first guide rail 8, the second guide rail 9, and the mounting frame 4. That is, when the receiving plate 5 needs to move away from the receiving frame 2, the receiving plate 5 drives the multi-segment telescopic guide rail to extend outward synchronously, providing sufficient strength and deflection to ensure that the side of the receiving plate 5 away from the brush plate 6 has a sufficiently long guide rail to provide support, thus keeping the receiving plate 5 in a horizontal state. This ensures that the horizontal height error of the receiving plate 5 is always kept within the allowable range, ensuring that the expected functional effect is achieved.

[0036] Example 3

[0037] like Figures 1-6 As shown, the flipping assembly includes a mounting frame 4 with a connecting frame 11 and an adjusting motor 14 mounted on one end. Both the connecting frame 11 and the adjusting motor 14 are mounted on one end of the mounting frame 4. A rotating rod 12 rotatably passes through the inside of the connecting frame 11. One end of the rotating rod 12 located inside the connecting frame 11 is connected to a connecting plate 13. One end of the connecting plate 13 is connected to a receiving plate 5. A pulley assembly 15 is provided between the output end of the adjusting motor 14 and the rotating rod 12.

[0038] During operation, by driving the output end of the regulating motor 14 to rotate 180 degrees in the forward direction, under the transmission action of the pulley group 15, the rotating rod 12 can drive the connecting plate 13 to rotate around one end of the mounting bracket 4 as the base point, thereby achieving the effect of driving the receiving plate 5 and the brush plate 6 to flip.

[0039] Example 4

[0040] like Figures 1-6 As shown, the cleaning assembly includes a support frame 17, which is installed on one side of the receiving frame 2. A servo motor 19 is installed on one side of the middle of the support frame 17. A lead screw 18 connected to the output end of the servo motor 19 is rotatably passed through the middle of the support frame 17. A slide plate 20 is connected to the lead screw 18 and the lead screw nut pair. A scraper 21 is installed on one side of the slide plate 20.

[0041] like Figures 1-6As shown, the cleaning assembly also includes a transmission rack 22, a first connecting frame 23, and a second connecting frame 24. The transmission rack 22 is installed at both ends of the support frame 17. The first connecting frame 23 and the second connecting frame 24 are both installed at both ends of the slide plate 20. A first transmission rod 25 is rotatably passed through one end of the first connecting frame 23, and a second transmission rod 26 is rotatably connected to one end of the second connecting frame 24. A bevel gear set 27 is provided between the first transmission rod 25 and the second transmission rod 26. A transmission gear 28 that meshes with the transmission rack 22 is installed at one end of the second transmission rod 26. Multiple sets of circular plates 29 are installed on the first transmission rod 25. Each set of circular plates 29 is opposite to the edge of each set of brush plates 6. A protrusion 31 slides through the inside of the circular plate 29. A spring 30 is provided between the inside of the circular plate 29 and the protrusion 31.

[0042] like Figures 1-6 As shown, the cleaning assembly also includes an air delivery frame 32, which is installed on one side of the slide plate 20. Multiple sets of nozzles 33 are connected to the air delivery frame 32. An air delivery pipe 16 is connected inside one side of the air delivery frame 32. One end of the air delivery pipe 16 is connected to an external pump, and the pump delivers the airflow into the air delivery pipe 16.

[0043] During operation, the intermittent forward and reverse rotation of the output of the drive regulating motor 14 drives the transmission screw 18 to move the slide plate 20 back and forth. The scraper 21 moves back and forth to contact the soft bristles on the surface of the brush plate 6 in the flipped state, so as to remove impurities, debris and dust attached to the surface of the brush plate 6. At the same time, when the scraper 21 moves, it drives the transmission gear 28 to mesh with the transmission rack 22 through the first connecting frame 23 and the second transmission rod 26, thereby driving the second transmission rod 26 to rotate. At this time, the second transmission rod 26 drives the first transmission rod 25 to rotate through the bevel gear set 27, so that the first transmission rod 25 drives multiple sets of circular plates 29 to rotate. The protrusions 31 tap the areas on both sides of the brush plate 6 where no brushes are installed, helping to shake off the dust or impurities attached to these areas. At the same time, the air supply pipe 16 delivers the cleaning air to the air supply frame 32, and then sprays it out through multiple sets of nozzles 33 to further help remove dust and impurities on the brush plate 6, ensuring the cleaning effect.
