Description

Technical Field

[0001] This utility model relates to the field of metal sheet surface treatment technology, and in particular to a roller brush chamfering device. Background Technology

[0002] The roller brush chamfering equipment is equipped with multiple high-speed rotating roller brushes, which can revolve under the drive of a longitudinal axis. When grinding the surface and edges of the metal sheet, the conveyor belt carries the metal sheet through the roller brushes, and the high-speed rotating roller brushes grind the surface and edges of the metal sheet, thereby completing the deburring and edge chamfering process.

[0003] Since roller brushes use friction to polish metal sheets, they are consumable parts and need to be replaced regularly to ensure the quality of the chamfering. However, existing roller brush chamfering equipment typically mounts the roller brush onto a rotating shaft and then secures it with a nut. Therefore, there are the following drawbacks when disassembling and assembling the roller brush:

[0004] When installing the roller brush, a wrench is needed to tighten the nut to prevent the nut from loosening and falling off due to the huge vibration generated during the high-speed rotation of the roller brush. Therefore, when disassembling and assembling the roller brush, a large force needs to be used with a wrench to turn the nut, which makes the disassembly and assembly of the roller brush time-consuming and laborious, affecting the efficiency of replacing the roller brush later. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to provide a roller brush chamfering device, which aims to solve the problem that the disassembly and assembly of roller brushes in existing roller brush chamfering devices is time-consuming and labor-intensive.

[0007] To achieve the above objectives, one embodiment of the present invention provides a roller brush chamfering device, including a frame, a chamfering assembly, a roller brush, a conveyor belt, a lifting assembly, and a collar;

[0008] The chamfering assembly includes a revolution shaft, which is rotatably connected to the top of the frame via a bearing. A suspension beam is fixedly connected to the bottom end of the revolution shaft. Multiple rotatable spindles are mounted on the bottom of the suspension beam via bearing seats. The roller brush is mounted on the outer surface of the spindle.

[0009] An oblique hole is provided on the outer surface of the end of the self-rotating shaft. A spring is provided inside the oblique hole, and a positioning post is slidably inserted inside the oblique hole. A limit ring is fixedly connected to the outer surface of the self-rotating shaft. An end cap is fixed to the end of the self-rotating shaft by bolts, and a positioning groove is provided on one side of the end cap at a position corresponding to the positioning post.

[0010] The roller brush includes a roller and bristles. The bristles are fixed on the outer surface of the roller, and a groove adapted to the positioning post is provided on the inner wall of one end of the roller.

[0011] A plug that matches the slot is fixedly connected to one side of the collar.

[0012] The beneficial effects are as follows: When disassembling the roller brush, after the collar is placed on the outer surface of the end cap, the collar is slid to allow the plug to be inserted into the slot, and the positioning pin retracts into the inclined hole, losing its limiting function on the roller. The roller brush can then be directly pulled out from the surface of the rotating shaft. When installing the roller brush, the roller is placed on the end of the rotating shaft, and then the roller brush is pushed towards the limiting ring. The positioning pin is first pushed into the inclined hole. When the roller touches the limiting ring, the positioning pin extends out of the inclined hole and is engaged in the slot. Thus, the limiting ring and the positioning pin limit the two ends of the roller respectively, achieving the purpose of fixing the roller brush and completing the installation of the roller brush. Therefore, it is convenient to disassemble and assemble the roller brush, saving time and effort and improving the efficiency of replacing the roller brush.

[0013] Furthermore, a motor is fixedly installed on the top of the frame, and a pulley is keyed to the output shaft of the motor. A second pulley is keyed to the outer surface of the revolution shaft, and the pulleys are connected by a belt.

[0014] Furthermore, a second motor is fixedly installed on the top of the suspension beam, a third pulley is keyed to the output end of the second motor, a fourth pulley is keyed to the outer surface of the rotating shaft, and the third and fourth pulleys are connected by a second belt.

[0015] Furthermore, the revolution shaft is hollow, and a conductive slip ring is installed inside the top end of the revolution shaft.

[0016] Furthermore, a threaded hole is provided at the end of the rotating shaft, and a bolt is threaded into the inside of the threaded hole. An end cap is fitted onto the outer surface of the bolt, and the end cap is fixed to the end of the rotating shaft by the bolt.

[0017] Furthermore, the lifting assembly includes four worm gear lifts installed in the frame, with the top ends of the lifting screws of the four worm gear lifts fixed to the bottom of the frames on both sides of the conveyor belt.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] This invention provides a roller brush chamfering device.

[0032] Example 1:

[0033] like Figure 1 As shown, it includes a frame 1, a chamfering assembly 2, a roller brush 3, a conveyor belt 5, and a lifting assembly 6.

[0034] like Figure 2-3 As shown, the chamfering assembly 2 includes a revolution shaft 21, which is rotatably connected to the top of the frame 1 via a bearing. A suspension beam 22 is welded and fixed to the bottom end of the revolution shaft 21. Multiple rotatable spin shafts 23 are mounted on the bottom of the suspension beam 22 via bearing seats. The roller brush 3 is mounted on the outer surface of the spin shaft 23.

[0035] like Figure 1 As shown, a motor 40 is fixedly installed on the top of the frame 1. A pulley 401 is keyed to the output shaft of the motor 40. A pulley 402 is keyed to the outer surface of the revolution shaft 21. The pulley 401 and the pulley 402 are connected by a belt 403. The motor 40 can drive the revolution shaft 21 to rotate, thereby driving the roller brush 3 to revolve.

[0036] like Figure 2-3 As shown, a second motor 41 is fixedly installed on the top of the suspension beam 22. A third pulley 411 is keyed to the output end of the second motor 41. A fourth pulley 412 is keyed to the outer surface of the rotating shaft 23. The third pulley 411 and the fourth pulley 412 are connected by a second belt 413. The second motor 41 can drive the rotating shaft 23 to rotate, thereby driving the roller brush 3 to rotate. The revolution shaft 21 is hollow, and a conductive slip ring 9 is installed inside its top end. The conductive slip ring 9 is used to connect the power supply cable to the power line of the second motor 41 to ensure that the cable will not get tangled during the rotation of the revolution shaft 21.

[0037] like Figure 1 As shown, the conveyor belt 5 is connected to the inside of the frame 1 by the lifting assembly 6, and the distance between the top surface of the conveyor belt 5 and the chamfering assembly 2 can be adjusted, so that metal sheet workpieces of different thicknesses can be ground and chamfered.

[0038] like Figure 5-7As shown, an oblique hole 231 is provided on the outer surface of the end of the rotating shaft 23. A spring 232 is provided inside the oblique hole 231, and a positioning pin 233 is slidably inserted into the oblique hole 231. A threaded hole 234 is provided at the end of the rotating shaft 23. A bolt 235 is threadedly connected inside the threaded hole 234. An end cap 7 is fitted on the outer surface of the bolt 235. The end cap 7 is fixed to the end of the rotating shaft 23 by the bolt 235. A positioning groove 71 is provided on one side of the end cap 7 at a position corresponding to the positioning pin 233. The positioning pin 233 is inserted into the positioning groove 71, and the end of the positioning pin 233 abuts against the inner wall of the positioning groove 71, so that the positioning pin 233 cannot fall out of the oblique hole 231.

[0039] like Figure 5 and Figure 8 As shown, the roller brush 3 includes a roller 31, with bristles 32 fixed on the outer surface of the roller 31. A groove 33 adapted to the positioning post 233 is opened on the inner wall of one end of the roller 31. When the roller 31 is fitted onto the outer surface of the rotating shaft 23, the groove 33 is fitted onto the outer surface of the positioning post 233. A limit ring 236 is welded and fixed to the outer surface of the rotating shaft 23. The limit ring 236 and the positioning post 233 limit the two ends of the roller 31 respectively, thereby achieving the purpose of fixing the roller brush 3.

[0040] like Figure 4 As shown, it also includes a collar 8, one side of which is fixedly connected to a plug 81 that is compatible with the slot 33. When the collar 8 is fitted onto the outer surface of the end cover 7 and the plug 81 is inserted into the slot 33, the plug 81 can press against the positioning post 233 and insert it into the inclined hole 231, thereby disengaging the positioning post 233 from the slot 33, and the roller 31 and the collar 8 can be pulled out from the outer surface of the rotating shaft 23.

[0041] The working principle of this embodiment is as follows: When replacing the severely worn roller brush 3, the collar 8 is placed on the outer surface of the end cover 7 and the collar 8 is slid in the direction of the roller brush 3 so that the plug 81 is inserted into the slot 33. During the insertion process, the plug 81 presses against the positioning post 233. Since the end face of the positioning post 233 is inclined, the positioning post 233 slides into the inclined hole 231 after being subjected to the force of the plug 81, until there is no protruding positioning post 233 on the surface of the rotating shaft 23. At this time, the roller brush 3 is pulled outward, and the roller brush 3 and the collar 8 can be directly pulled out from the outer surface of the rotating shaft 23 to complete the disassembly of the roller brush 3.

[0042] When installing a new roller brush 3, simply place the roller 31 of the roller brush 3 onto the end of the rotating shaft 23, and then push the roller brush 3 toward the limiting ring 236. After the roller 31 presses against the positioning post 233, it will push the positioning post 233 into the inclined hole 231 until the end of the roller 31 touches the limiting ring 236. Then, the spring 232 pushes the positioning post 233 out of the inclined hole 231 and into the slot 33. At this point, the installation of the roller brush 3 is completed.

[0043] Example 2:

[0044] like Figure 1 As shown, based on Embodiment 1, the lifting assembly 6 includes four worm gear lifts installed in the frame 1. The top ends of the lifting screws of the four worm gear lifts are fixed to the bottom of the frames on both sides of the conveyor belt 5. By raising and lowering the top ends of the screws of the four worm gear lifts, the purpose of lifting the conveyor belt 5 is achieved, thereby adjusting the distance between the conveyor belt 5 and the chamfering assembly 2, and achieving the purpose of grinding and chamfering the metal sheet workpiece.
