Description

Technical Field

[0001] This invention belongs to the field of mechanical design, and in particular to a disc-type brush machine. Background Technology

[0002] With scientific advancements and improved living standards, people have increasingly higher demands for the quality of various products. Pipes, as a convenient component, have a wide range of applications. When pipes are first manufactured through cutting, especially metal pipes, they usually have some burrs and flash at both ends. In many cases, in order to maintain a good appearance and function during use, it is necessary to deburr and flash treatment at both ends of the pipe.

[0003] The existing brush machines used for grinding both ends of pipes, such as Chinese patent CN 116100401 A, have only one brush for grinding one side of the pipe end, and the rotation direction cannot be changed, meaning there is only one grinding direction. This results in blind spots and residues during grinding. Furthermore, the position of the brush machine between the grinding mechanisms on both sides of the pipe is immovable, meaning that one brush machine can only adapt to one length dimension. If different sizes of pipes need to be processed, brush machines of different sizes must be produced or purchased, resulting in high equipment costs and space requirements. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides a disc-type brush machine that can grind burrs and flash at both ends of tubular workpieces without dead angles and has good adaptability to the length and shape of the workpiece.

[0005] The technical solution adopted by this invention to solve its technical problem is: A disc-type brush machine includes a fixed base 1 and a fixed grinding mechanism 3 and a movable grinding mechanism 4, which are arranged opposite each other on the fixed base to support the two ends of a workpiece 2 and to remove burrs and flash from the ends of the workpiece 2. The fixed grinding mechanism 3 is fixedly mounted on the fixed base 1. The movable grinding mechanism 4 is mounted on the fixed base 1 via a movable seat 5 located above the fixed base 1 and adjustable in left and right position. The movable seat 5 is mounted on the fixed base 1 via a linear guide rail 19 to achieve left and right position adjustment. The fixed grinding mechanism 3 and the movable grinding mechanism 4 have the same structure, both including a support disc 6 and a pressing unit 7 arranged in front of and behind each other. The support disc 6 is located at the rear. On the outer side of the outer circle of the outer side of the outer side of the outer side of the outer side of the support disc 6 near the outer side of the outer side of the pressing unit 7, a brush unit 8 is also provided for removing burrs and flash from the ends of the workpiece 2. The support disc 6 is rotatably mounted on a fixed base 1 or a movable base 5 located directly below it. The disc surfaces of the two support discs 6 are arranged opposite each other and are synchronously driven to rotate by the same motor 9 through a synchronous shaft 10. The support disc 6 has a plurality of workpiece positioning grooves 61 uniformly provided on its outer circumference, which are adapted to the end structure of the workpiece. The workpiece positioning grooves 61 on the two support discs 6 correspond one to one. Above each support disc 6, a gravity discharge groove 11 is also fixedly provided for continuously feeding the workpiece positioning grooves 61 on the support disc. The two gravity discharge grooves 11 are both fixedly mounted on the fixed base 1 or the movable base 5 located directly below it by brackets and are arranged opposite each other to limit the two ends of the workpiece 2. The pressing unit 7 includes three pulleys arranged in a triangle and a flexible belt 71 sleeved between the three pulleys for transmission. Two of the three pulleys are fixed pulleys 72, and the other is a movable pulley 73. A tension adjusting device 74 is connected to the movable pulley 73 to adjust the tension of the flexible belt 71. The two fixed pulleys 72 are arranged one above the other and closely attached to the uppermost and lowermost ends of the support disc 6. The flexible belt 71 between the two fixed pulleys 72 is closely attached to the front outer edge of the support disc 6 so that the workpiece 2 can be pressed tightly into the workpiece positioning groove 61 on the support disc 6 without falling off. The upper fixed pulley 72 is also close to the front end of the gravity discharge groove 11 so as to press the workpiece 2 that falls into the gravity discharge groove 11 in time. The two fixed pulleys 72 and the tension adjusting device 74 are all fixedly mounted above the fixed base 1 or the movable base 5 located directly below them. The brush unit 8 includes at least one brush 81, each brush 81 being driven to rotate by a brush motor 82. Each brush 81 is adjustable in position (front-back, left-right) and mounted on a fixed base 1 or a movable base 5 directly below it. The brush units 8 on the fixed grinding mechanism 3 and the movable grinding mechanism 4 are arranged opposite each other, with the end faces of each brush 81 facing inward. Thus, each brush 81 can be individually adjusted in left-right position relative to the supporting disc 6 to compensate for wear during feed or to meet the different cutting depth requirements of different brushes 81 on the workpiece 2. Brushes 81 located on the same side can also synchronously adjust their front-back position relative to the supporting disc 6 to simultaneously reach the end of the workpiece 2, solving the problem of the workpiece 2 being too thin to reach the working end face of the brush 81.

[0006] Preferably, the brush unit 8 is mounted on a fixed base 1 or a movable base 5 located directly below it, with the upper and lower movable platforms working together and the front, back, left and right positions adjustable. It includes two brushes 81 that are driven to rotate by brush motors 82. The two brushes 81 are arranged one above the other with the center of the supporting disc as the reference. The upper brush 81 is adjustable in the left and right position relative to the lower brush 81. The two brushes 81 rotate in opposite directions to facilitate cleaning the end face of the workpiece 2 without dead angles.

[0007] More preferably, the brush unit 8 is provided with a first moving platform 12 that can move left and right relative to the fixed base 1 or moving seat 5 located directly below it, and a second moving platform 13 located above the first moving platform 12 that can move back and forth relative to the first moving platform 12. By cooperating in moving the first moving platform 12 and the second moving platform 13, the brush unit 8 can be adjusted in position in the left, right, and forward directions above the fixed base 1 or moving seat 5 located directly below it. The lower brush 81 of the brush unit 8 is fixedly mounted on the second moving platform 13, and the upper brush 81 is fixedly mounted on the third moving platform 14. The third moving platform 14 is movable left and right on the gate-shaped bracket 15 fixed above the second moving platform 13. By moving the third moving platform 14, the upper brush 81 can be adjusted in position left and right relative to the lower brush 81. The first moving platform 12 below the brush unit 8 in the fixed position grinding mechanism 3 can be movable left and right on the fixed base 1, and the first moving platform 12 below the brush unit 8 in the moving position grinding mechanism 4 can be movable left and right on the moving seat 5.

[0008] Furthermore, the movement of the movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 is all achieved by driving a linear drive mechanism 16. Furthermore, the linear drive mechanism 16 is a lead screw and nut sleeve linear drive mechanism, comprising a lead screw and a nut sleeve. The movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 are all fixedly connected to the nut sleeve in the lead screw and nut sleeve linear drive mechanism. Rotating the lead screw allows the nut sleeve to move them left and right along the lead screw, thereby achieving left-right or forward-backward movement. Furthermore, a locking and positioning structure 17 is also provided in conjunction with the movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 to fix their positions after they have moved into place.

[0009] The specific method by which the linear drive mechanism of the lead screw and nut sleeve drives linear movement is the existing known technology. For example, in this embodiment, the first moving platform 12 has a U-shaped structure. The lead screw 161 in the linear drive mechanism of the lead screw and nut sleeve used to drive the first moving platform 12 is mounted on an L-shaped support plate 164 that is fixedly connected to the fixed base 1 or the moving seat 5 located directly below it. The nut sleeve 162 is threaded onto the lead screw 161 and is fixedly connected to the first moving platform 12. The rear end of the lead screw 161 is provided with a handle 163 for driving its rotation. The fixed base 1 or the moving seat 5 located directly below the first moving platform 12 is also provided with two guide limiting strips 165 that can move and guide the two inner sides of the lower end of the U-shaped structure. Thus, by rotating the screw 162 with the handle 163, the first moving platform 12, which is fixedly connected to the nut sleeve 162, can move left and right along the screw, thereby enabling it to move left and right relative to the fixed base 1 or the moving seat 5 located directly below it; after moving into place, the first moving platform 12 is fixed to the fixed base 1 or the moving seat 5 located directly below it by the commonly used locking and positioning structure 17 (i.e., fixing the locking nut into the pre-dug elongated hole).

[0010] Preferably, the brush 81 is a disc-shaped brush.

[0011] Preferably, the support disc 6 in the fixed-position grinding mechanism 3 is fixedly mounted on the fixed base 1 by a bracket, and the support disc 6 in the movable-position grinding mechanism 4 is fixedly mounted on the movable seat 5 by a bracket; the two fixed pulleys 72 and the tension adjustment device 74 in the fixed-position grinding mechanism 3 are all fixedly mounted on the fixed base 1, and the two fixed pulleys 72 and the tension adjustment device 74 in the movable-position grinding mechanism 4 are mounted on the movable seat.

[0012] Preferably, an arc-shaped limiting baffle 18 is also fixedly provided on the outer circumference of the supporting disc 6 and between the supporting disc 6 and the brush unit 8, so as to first position the positions of the two ends of the workpiece 2 so that the brush unit 8 can polish it later. The arc-shaped limiting baffle 18 is fixedly connected to the fixed base 1 or the movable base 5 located directly below it.

[0013] Preferably, a downward-pointing scale pointer 51 is fixedly provided on the movable seat 5, and a scale ruler 20 is provided on the fixed base 1 in cooperation with the scale pointer 51. The distance moved by the movable seat 5 can be known by the position of the scale pointer 51 on the scale ruler 20.

[0014] Preferably, a workpiece unloading groove 21 is also provided on the fixed base 1, below the space between the two supporting discs 6.

[0015] More preferably, the workpiece unloading groove 21 is an inclined groove.

[0016] The tension adjustment device 74 is also a tension adjustment structure commonly used in the prior art, which adjusts the tension by pulling the movable pulley further or closer.

[0017] The beneficial effects of this invention are: The disc-type brush machine of this invention has an ingenious structure. It uses two supporting discs to support the two ends of the workpiece, a flexible belt to press the workpiece, and brush units on both sides to thoroughly clean both ends of the pipe, efficiently removing burrs and flash from both ends. Furthermore, when the brush unit has two brushes rotating in opposite directions, it can better achieve all-around, no-dead-angle cleaning of both end faces of the workpiece, resulting in excellent cleaning effect. In addition, because the position of the moving grinding mechanism relative to the fixed grinding mechanism is adjustable, it can handle workpieces of different lengths. When the end structure of the workpiece changes, it is only necessary to replace the supporting disc with one whose workpiece positioning groove structure is adapted to the end structure of the new workpiece, resulting in very low modification costs. Therefore, this invention can grind burrs and flash from both ends of tubular workpieces without dead angles and has excellent adaptability to the length and shape of the workpiece, making it highly practical and worthy of promotion.

[0021] like Figure 1-11 As shown, the disc-type brush machine includes a fixed base 1 and a fixed grinding mechanism 3 and a movable grinding mechanism 4, which are arranged opposite each other on the fixed base to support the two ends of the workpiece 2 and to remove burrs and flash from the two ends of the workpiece 2. The fixed grinding mechanism 3 is fixedly mounted on the fixed base 1. The movable grinding mechanism 4 is mounted on the fixed base 1 by means of a movable seat 5 located above the fixed base 1 and whose left and right positions are adjustable. The movable seat 5 is mounted on the fixed base 1 by means of a linear guide rail 19 to achieve left and right position adjustment. The fixed grinding mechanism 3 and the movable grinding mechanism 4 have the same structure, both including a support disc 6 and a pressing unit 7 arranged in front of and behind each other. The support disc 6 is located at the rear. On the outer side of the outer circle of the outer side of the outer side of the outer side of the outer side of the support disc 6 near the outer side of the outer side of the pressing unit 7, a brush unit 8 is also provided for removing burrs and flash from the ends of the workpiece 2. The support disc 6 is rotatably mounted on a fixed base 1 or a movable base 5 located directly below it. The disc surfaces of the two support discs 6 are arranged opposite each other and are synchronously driven to rotate by the same motor 9 through a synchronous shaft 10. The support disc 6 has a plurality of workpiece positioning grooves 61 uniformly provided on its outer circumference, which are adapted to the end structure of the workpiece. The workpiece positioning grooves 61 on the two support discs 6 correspond one to one. Above each support disc 6, a gravity discharge groove 11 is also fixedly provided for continuously feeding the workpiece positioning grooves 61 on the support disc. The two gravity discharge grooves 11 are both fixedly mounted on the fixed base 1 or the movable base 5 located directly below it by brackets and are arranged opposite each other to limit the two ends of the workpiece 2. The pressing unit 7 includes three pulleys arranged in a triangle and a flexible belt 71 sleeved between the three pulleys for transmission. Two of the three pulleys are fixed pulleys 72, and the other is a movable pulley 73. A tension adjusting device 74 is connected to the movable pulley 73 to adjust the tension of the flexible belt 71. The two fixed pulleys 72 are arranged one above the other and closely attached to the uppermost and lowermost ends of the support disc 6. The flexible belt 71 between the two fixed pulleys 72 is closely attached to the front outer edge of the support disc 6 so that the workpiece 2 can be pressed tightly into the workpiece positioning groove 61 on the support disc 6 without falling off. The upper fixed pulley 72 is also close to the front end of the gravity discharge groove 11 so as to press the workpiece 2 that falls into the gravity discharge groove 11 in time. The two fixed pulleys 72 and the tension adjusting device 74 are all fixedly mounted above the fixed base 1 or the movable base 5 located directly below them. The brush unit 8 includes at least one brush 81, each brush 81 being driven to rotate by a brush motor 82. Each brush 81 is adjustable in position (front-back, left-right) and mounted on a fixed base 1 or a movable base 5 directly below it. The brush units 8 on the fixed grinding mechanism 3 and the movable grinding mechanism 4 are arranged opposite each other, with the end faces of each brush 81 facing inward. Thus, each brush 81 can be individually adjusted in left-right position relative to the supporting disc 6 to compensate for wear during feed or to meet the different cutting depth requirements of different brushes 81 on the workpiece 2. Brushes 81 located on the same side can also synchronously adjust their front-back position relative to the supporting disc 6 to simultaneously reach the end of the workpiece 2, solving the problem of the workpiece 2 being too thin to reach the working end face of the brush 81.

[0022] Specific examples of the workpiece positioning groove 61 being adapted to the workpiece end structure include: when the workpiece (2) is a circular tube, the workpiece positioning groove (61) is semi-circular with a radius matching the outer diameter of the tube; when the workpiece (2) is a square tube, the workpiece positioning groove (61) is rectangular with a size matching the end of the tube.

[0023] Preferably, the brush unit 8 is mounted on a fixed base 1 or a movable base 5 located directly below it, with the upper and lower movable platforms working together and the front, back, left and right positions adjustable. It includes two brushes 81 that are driven to rotate by brush motors 82. The two brushes 81 are arranged one above the other with the center of the supporting disc as the reference. The upper brush 81 is adjustable in the left and right position relative to the lower brush 81. The two brushes 81 rotate in opposite directions to facilitate cleaning the end face of the workpiece 2 without dead angles.

[0024] More preferably, the brush unit 8 is provided with a first moving platform 12 that can move left and right relative to the fixed base 1 or moving seat 5 located directly below it, and a second moving platform 13 located above the first moving platform 12 that can move back and forth relative to the first moving platform 12. By cooperating in moving the first moving platform 12 and the second moving platform 13, the brush unit 8 can be adjusted in position in the left, right, and forward directions above the fixed base 1 or moving seat 5 located directly below it. The lower brush 81 of the brush unit 8 is fixedly mounted on the second moving platform 13, and the upper brush 81 is fixedly mounted on the third moving platform 14. The third moving platform 14 is movable left and right on the gate-shaped bracket 15 fixed above the second moving platform 13. By moving the third moving platform 14, the upper brush 81 can be adjusted in position left and right relative to the lower brush 81. The first moving platform 12 below the brush unit 8 in the fixed position grinding mechanism 3 can be movable left and right on the fixed base 1, and the first moving platform 12 below the brush unit 8 in the moving position grinding mechanism 4 can be movable left and right on the moving seat 5.

[0025] Furthermore, the movement of the movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 is all achieved by driving a linear drive mechanism 16. Furthermore, the linear drive mechanism 16 is a lead screw and nut sleeve linear drive mechanism, comprising a lead screw and a nut sleeve. The movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 are all fixedly connected to the nut sleeve in the lead screw and nut sleeve linear drive mechanism. Rotating the lead screw allows the nut sleeve to move them left and right along the lead screw, thereby achieving left-right or forward-backward movement. Furthermore, a locking and positioning structure 17 is also provided in conjunction with the movable seat 5, the first movable platform 12, the second movable platform 13, and the third movable platform 14 to fix their positions after they have moved into place.

[0026] The linear drive mechanism of the lead screw and nut sleeve is driven by existing known technologies and methods. For example, in this embodiment, the first moving platform 12 has a U-shaped structure. The lead screw 161 of the linear drive mechanism of the lead screw and nut sleeve is mounted on an L-shaped support plate 164 that is fixedly connected to the fixed base 1 or the moving seat 5 located directly below it. The nut sleeve 162 is threaded onto the lead screw 161 and is fixedly connected to the first moving platform 12. The rear end of the lead screw 161 is provided with a handle 163 for driving its rotation. The fixed base 1 or the moving seat 5 located directly below the first moving platform 12 is also provided with two guide limiting strips 165 that can guide the movement of the two inner sides of the lower end of the U-shaped structure. Thus, by rotating the screw 162 with the handle 163, the first moving platform 12, which is fixedly connected to the nut sleeve 162, can move left and right along the screw, thereby enabling it to move left and right relative to the fixed base 1 or the moving seat 5 located directly below it; after moving into place, the first moving platform 12 is fixed to the fixed base 1 or the moving seat 5 located directly below it by the commonly used locking and positioning structure 17 (i.e., fixing the locking nut into the pre-dug elongated hole).

[0027] Preferably, the brush 81 is a disc-shaped brush.

[0028] Preferably, the support disc 6 in the fixed-position grinding mechanism 3 is fixedly mounted on the fixed base 1 by a bracket, and the support disc 6 in the movable-position grinding mechanism 4 is fixedly mounted on the movable seat 5 by a bracket; the two fixed pulleys 72 and the tension adjustment device 74 in the fixed-position grinding mechanism 3 are all fixedly mounted on the fixed base 1, and the two fixed pulleys 72 and the tension adjustment device 74 in the movable-position grinding mechanism 4 are mounted on the movable seat.

[0029] Preferably, an arc-shaped limiting baffle 18 is fixedly provided on the outer circumference of the supporting disk 6 and between the supporting disk 6 and the brush unit 8 to facilitate pre-positioning of the positions of both ends of the workpiece 2 for subsequent grinding by the brush unit 8. The arc-shaped limiting baffle 18 is fixedly connected to the fixed base 1 or the movable base 5 located directly below it. More preferably, the arc of the arc-shaped limiting baffle 18 is consistent with the arc of the supporting disk 6, and the arc length is 1 / 4 of the circumference of the supporting disk.

[0030] Preferably, a downward-pointing scale pointer 51 is fixedly provided on the movable seat 5, and a scale ruler 20 is provided on the fixed base 1 in cooperation with the scale pointer 51. The distance moved by the movable seat 5 can be known by the position of the scale pointer 51 on the scale ruler 20.

[0031] Preferably, a workpiece unloading groove 21 is also provided on the fixed base 1, below the space between the two supporting discs 6.

[0032] More preferably, the workpiece unloading groove 21 is an inclined groove.

[0033] The tension adjusting device 74 is also a commonly used tension adjusting structure in the prior art, which adjusts the tension by pulling the movable pulley closer or further away. For example, in this embodiment, the tension adjusting device 74 includes a movable frame fixedly connected to the movable pulley, a screw threaded to the movable frame, and a nut for locking. By rotating the screw, the movable frame is pulled forward or backward, changing the position of the movable pulley 73, thereby adjusting the tension of the flexible belt 71. After the movable frame is moved into place, the movable frame is locked by the nut.

[0034] In this embodiment, the brush machine operates according to the sequence of material feeding → fixing → grinding → unloading, as follows: 1. Feeding: The horizontally placed workpiece 2 automatically falls between two gravity-feeding grooves 11, and its two ends are embedded in the workpiece positioning grooves 61 of the two support discs 6 (one-to-one correspondence); the support discs 6 rotate continuously to receive the next workpiece in sequence; 2. Fixing: The support disc 6 is driven to rotate by the motor 9 through the synchronous shaft 10. The flexible belt 71 of the pressing unit 7 (arranged in a triangle) is close to the front outer edge of the support disc 6. When the workpiece 2 enters between the flexible belt 71 and the support disc 6, the flexible belt 71 presses the workpiece 2 into the positioning groove 61 to prevent it from falling off. 3. Grinding: The support disc 6 drives the workpiece 2 to rotate to the position of the brush unit 8. The end faces of the two brushes 81 (set up and down and rotating in opposite directions) contact the end of the workpiece 2 and remove burrs by high-speed rotation. The front, back, left and right positions of the brushes 81 can be adjusted by the cooperation of the first, second and third moving platforms to adapt to the end size of the workpiece or adjust the feed rate as needed. 4. Unloading: When the workpiece 2 rotates with the support disc 6 to the lowest point, the flexible belt 71 separates from the support disc 6, the workpiece 2 loses the clamping force, and falls from the workpiece positioning groove 61 into the workpiece unloading groove 21 below, completing the grinding.

[0035] During this process, the flexible belt 71 moves synchronously with the support disc 6 to press the workpiece 2, and the pressing force of the flexible belt 71 is adjusted by the tension adjustment device 74 according to the working conditions.

[0036] That is, the horizontally placed workpiece is automatically unloaded and its two ends are fixed in the workpiece positioning grooves on the outer circumference of two continuously rotating support discs, which drive the continuous circumferential rotation. After the workpiece enters the grinding zone of the brush unit, both ends are pressed and fixed by a flexible belt, which moves synchronously with the support discs pressing the workpiece. The pressing force of the flexible belt is adjusted by a tension regulating device according to the working conditions. In actual production, the number of brush units used is determined as needed. The brush has a disc-shaped structure, and through the high-speed rotation of the brush, the end faces of the brush thoroughly clean both ends of the pipe, thereby achieving the cleaning effect of the pipe end faces.

[0037] When the supporting disc drives the workpiece to make a circular motion and enter the grinding area of ​​the two relatively rotating brush units, the workpiece moves through the brush grinding area in a curved motion. When there are two brushes on each brush unit and they rotate in opposite directions, the brush unit performs all-round cleaning of the end faces of the workpiece without dead angles, thereby achieving a thorough cleaning of the end faces of the workpiece.

[0038] Therefore, the disc-type brush machine of the present invention has an ingenious structure. By supporting the two ends of the workpiece with two supporting discs, pressing the workpiece with a flexible belt, and having brush units located on both sides to thoroughly clean the two ends of the tube, it can efficiently remove burrs and flash from the ends of the tube. In addition, when the brush unit is equipped with two brushes rotating in opposite directions, it can better achieve all-round cleaning of the end faces of the workpiece without dead angles, and the cleaning effect is excellent. Furthermore, because the position of the moving grinding mechanism relative to the fixed grinding mechanism is adjustable, it can handle workpieces of different lengths. When the end structure of the workpiece changes, it is only necessary to replace the supporting disc with a supporting disc whose workpiece positioning groove structure is adapted to the end structure of the new workpiece. The modification cost is very small. Therefore, the present invention can grind burrs and flash from both ends of tubular workpieces without dead angles and has excellent adaptability to the length and shape of the workpiece. It is highly practical and worthy of promotion.

[0039] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
