Description

Technical Field

[0001] This invention relates to the field of deburring equipment technology, and more particularly to a floating metal deburring machine. Background Technology

[0002] A deburring machine is a mechanical device used to remove burrs from the surface of workpieces, effectively improving the surface quality and machining accuracy. There are various types of deburring machines, among which the belt abrasive deburring machine is a common type. It uses an abrasive belt to perform high-speed grinding on the workpiece, removing burrs and flash, and can also perform surface treatments such as polishing and grinding.

[0003] The workpiece surface encountered during the use of deburring machines is not completely flat. Some workpiece surfaces have certain undulations due to different processing techniques. These surface undulations not only affect the deburring effect, but also cause the abrasive belt to jam. Announcement No.: CN 212350642 U discloses a reciprocating spring cutting deburring machine for continuous casting billets. This equipment can deburr uneven casting billet surfaces. However, this equipment uses a scraper deburring method, which is inefficient and cannot deburr large workpieces.

[0004] Therefore, a floating metal deburring machine is proposed to address the above problems. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a floating metal deburring machine. This invention can deburr uneven workpiece surfaces, improving deburring efficiency.

[0006] The technical solution of this invention to solve the technical problem is as follows: a floating metal deburring machine, including a mounting base, a conveyor belt on the mounting base, a first mounting frame and a second mounting frame respectively on both sides of the mounting base located on the conveyor belt, a working part between the first mounting frame and the second mounting frame, the working part including a pressure roller, a tension roller and an abrasive belt, the abrasive belt being wound around the pressure roller and the tension roller, the pressure roller being set between the first mounting frame and the second mounting frame through a floating device, the pressure roller being connected to a motor through an adjusting device, a main beam being set between the first mounting frame and the second mounting frame, a tension cylinder being set on the main beam, a connecting beam being set on the tension cylinder, and a tension roller being rotatably set on the connecting beam.

[0007] The motor drives the pressure roller, tension roller and sanding belt to rotate. The burrs on the workpiece are removed by the friction between the sanding belt and the workpiece. The workpiece is moved by the conveyor belt. When the surface of the workpiece is uneven, the sanding belt follows the surface of the workpiece under the action of the floating device to fully remove the burrs on the surface of the workpiece, while preventing the sanding belt from being jammed due to the unevenness of the workpiece surface.

[0008] Preferably, the floating device includes a connecting shaft, a mounting plate, a support plate, and a limiting groove. The connecting shafts are symmetrically arranged at both ends of the pressure roller, and the mounting plate is arranged on the connecting shaft. The mounting plate is rotatably arranged with respect to the connecting shaft. The support plate is arranged at the upper end of the mounting plate and passes through the limiting groove. The limiting groove is located on the first mounting frame and the second mounting frame.

[0009] The pressure roller moves up and down along the limiting groove under the action of the mounting plate and the support plate, thereby adjusting the height of the abrasive belt to adapt to the workpiece with uneven surface.

[0010] Preferably, the floating device also includes a support platform, a guide shaft, a compression spring, and a limiting nut. The support plate is slidably connected to the guide shaft on the outside of the mounting frame. The guide shaft is vertically mounted on the support platform. The support platform is located on the outside of the first mounting frame and the second mounting frame, respectively. A limiting nut is set above the guide shaft on the support plate. A compression spring is sleeved on the guide shaft. The upper end of the compression spring is connected to the support plate, and the lower end of the compression spring is connected to the support platform.

[0011] By setting a compression spring, the compression spring provides support to the support plate, and a certain gap is maintained between the sanding belt and the conveyor belt to ensure the normal deburring process of the workpiece. At the same time, the pressure roller and sanding belt can adapt to the undulations of the workpiece surface and adjust accordingly to the degree of undulation.

[0012] Preferably, the floating device also includes sliders and guide rails. Sliders are symmetrically arranged on the side of the mounting plate away from the pressure roller. The sliders are vertically arranged and the symmetrically arranged sliders are located on both sides of the connecting shaft. Guide rails are symmetrically arranged on the side of the first mounting bracket and the second mounting bracket near the mounting plate. The guide rails are vertically arranged and the length of the guide rails is greater than the length of the limiting groove. The symmetrically arranged guide rails are located on both sides of the connecting shaft, and the sliders slide on the guide rails.

[0013] By setting sliders and slide rails, the movement direction of the pressure roller is further limited to prevent the pressure roller from deviating from its intended path.

[0014] Preferably, the floating device also includes support bolts, connectors, support rods, mounting platforms, and hydraulic cylinder push rods. Support bolts are provided on the side of the support plate, connectors are fitted on the support bolts, and support rods are provided on the connectors. The support rods pass through the mounting platforms and are connected to the hydraulic cylinder push rods. The mounting platforms are set on the first mounting frame and the second mounting frame, and hydraulic cylinder push rods are set on the mounting platforms. The hydraulic cylinder push rods on both sides move synchronously.

[0015] The hydraulic cylinder push rod applies a certain pressure downward to the pressure roller to ensure the deburring effect and reduce the shaking of the pressure roller. At the same time, the hydraulic cylinder push rods on both sides ensure that the pressure roller can move vertically up and down, preventing the pressure roller from tilting during the deburring process of the workpiece.

[0016] Preferably, the adjustment device includes a support bearing, a coupling, and an adjustment groove. The connecting shafts at both ends of the pressure roller are mounted on the support bearing, which is located on the side of the mounting plate near the pressure roller. The first mounting frame is provided with an adjustment groove, and the connecting shaft passes through the adjustment groove and is connected to the coupling. The coupling is connected to the output end of the motor.

[0017] The coupling is a ball cage type constant velocity universal coupling. By setting the coupling, the pressure roller is still driven by the motor during the up and down movement, ensuring the normal rotation of the pressure roller.

[0018] Preferably, the working part also includes an adjusting bracket, a balancing cylinder, a balancing block, a balancing groove, an eccentric shaft, a mounting hole, and an adjusting seat. An adjusting bracket is installed on one side of the main beam, a balancing cylinder is installed on the adjusting bracket, a balancing block is installed at the output end of the balancing cylinder, the moving direction of the balancing block is perpendicular to the direction of the main beam, a balancing groove is vertically installed on the balancing block, an eccentric shaft is installed in the balancing groove, the upper end of the eccentric shaft is inserted into the mounting hole of the adjusting seat, and the adjusting seat is located at the lower end of the connecting beam.

[0019] When the angle of the connecting beam needs to be adjusted, the balancing cylinder is activated. The balancing cylinder pushes the balancing block and the eccentric shaft to move. The eccentric shaft pushes the adjusting seat and the connecting beam to rotate, thereby achieving angle adjustment. Through the cooperation of the eccentric shaft and the balancing groove, the misalignment between the eccentric shaft and the balancing block during the pushing process is not affected. The eccentric shaft is inserted into the balancing groove and moves up and down along the balancing groove without affecting the up and down movement of the sand belt.

[0020] Preferably, the working part also includes an annular groove, a threaded rod, a threaded hole, a retaining ring, a mounting groove, and an arc plate. The upper end of the eccentric shaft is provided with a retaining ring, and the upper end of the adjusting seat is provided with a mounting groove. The retaining ring is rotatably disposed in the mounting groove. The upper part of the eccentric shaft is provided with a threaded hole located in the mounting hole. The threaded hole is perpendicular to the eccentric shaft and is connected to the threaded rod. The threaded rod passes through the annular groove, which is located on the side of the adjusting seat. An arc plate is provided on the threaded rod, and the arc plate fits against the surface of the adjusting seat.

[0021] The retaining ring and the mounting groove work together to prevent the eccentric shaft from falling off. The threaded rod further locks the relative height of the eccentric shaft and makes it easier for operators to observe the angle. An arc plate is set to block the annular groove to reduce dust entry.

[0022] Preferably, a fixing platform is provided on the lower part of the side of the second mounting bracket away from the pressure roller. The fixing platform is connected to the positioning column by a mounting screw. The positioning column is set on the positioning seat, and the positioning seat is located on the mounting base.

[0023] The installation screw facilitates positioning and adjustment, reducing installation errors.

[0024] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects: The motor drives the pressure roller, tension roller and sanding belt to rotate. The burrs on the workpiece are removed by the friction between the sanding belt and the workpiece. The workpiece is moved by the conveyor belt. When the surface of the workpiece is uneven, the sanding belt follows the surface of the workpiece under the action of the floating device to fully remove the burrs on the surface of the workpiece, while preventing the sanding belt from being jammed due to the unevenness of the workpiece surface. By setting a compression spring, the compression spring provides support force to the support plate, and a certain gap is maintained between the sanding belt and the conveyor belt to ensure the normal deburring process of the workpiece. At the same time, the pressure roller and sanding belt can adapt to the undulations of the workpiece surface and adjust accordingly to the degree of undulation of the workpiece. The hydraulic cylinder push rod applies a certain pressure downward to the pressure roller to ensure the deburring effect and reduce the shaking of the pressure roller. At the same time, the hydraulic cylinder push rods on both sides ensure that the pressure roller can move vertically up and down, preventing the pressure roller from tilting during the deburring process of the workpiece.

[0034] like Figures 1 to 6As shown, a floating metal deburring machine includes a mounting base 1, a conveyor belt 2 on the mounting base 1, a first mounting frame 3 and a second mounting frame 4 on both sides of the mounting base 1 located on the conveyor belt 2, a working part between the first mounting frame 3 and the second mounting frame 4, the working part including a pressure roller 5, a tension roller 6 and an abrasive belt 7, the abrasive belt 7 being wound around the pressure roller 5 and the tension roller 6, the pressure roller 5 being set between the first mounting frame 3 and the second mounting frame 4 via a floating device, the pressure roller 5 being connected to a motor 46 via an adjusting device, a main beam 8 being set between the first mounting frame 3 and the second mounting frame 4, a tension cylinder 9 being set on the main beam 8, a connecting beam 10 being set on the tension cylinder 9, and the tension roller 6 being rotatably mounted on the connecting beam 10. Motor 46 drives the pressure roller 5, tension roller 6 and sanding belt 7 to rotate. The burrs on the workpiece are removed by the friction between the sanding belt 7 and the workpiece. The workpiece is moved by the conveyor belt 2. When the surface of the workpiece is uneven, the sanding belt 7 follows the surface of the workpiece under the action of the floating device to fully remove the burrs on the surface of the workpiece, while preventing the sanding belt 7 from being jammed due to the unevenness of the workpiece surface.

[0035] The floating device includes a connecting shaft 11, a mounting plate 12, a support plate 13, and a limiting groove 14. The connecting shaft 11 is symmetrically arranged at both ends of the pressure roller 5. The mounting plate 12 is mounted on the connecting shaft 11 and is rotatably mounted between the mounting plate 12 and the connecting shaft 11. The support plate 13 is mounted on the upper end of the mounting plate 12 and passes through the limiting groove 14, which is located on the first mounting frame 3 and the second mounting frame 4. Under the action of the mounting plate 12 and the support plate 13, the pressure roller 5 moves up and down along the limiting groove 14, thereby adjusting the height of the abrasive belt 7 to adapt to workpieces with uneven surfaces.

[0036] The floating device also includes a support platform 15, a guide shaft 16, a compression spring 17, and a limiting nut 18. The support plate 13 is located outside the mounting frame and slides onto the guide shaft 16. The guide shaft 16 is vertically mounted on the support platform 15. The support platform 15 is located outside the first mounting frame 3 and the second mounting frame 4, respectively. The limiting nut 18 is set above the guide shaft 16. The compression spring 17 is sleeved on the guide shaft 16. The upper end of the compression spring 17 is connected to the support plate 13, and the lower end of the compression spring 17 is connected to the support platform 15. By setting the compression spring 17, the compression spring 17 provides support force to the support plate 13, and a certain gap is maintained between the sanding belt 7 and the conveyor belt 2 to ensure the normal deburring process of the workpiece. At the same time, the pressure roller 5 and the sanding belt 7 can adapt to the undulations of the workpiece surface and adjust accordingly to the degree of undulation.

[0037] The floating device also includes sliders 19 and guide rails 20. Sliders 19 are symmetrically arranged on the side of the mounting plate 12 away from the pressure roller 5. The sliders 19 are vertically arranged and located on both sides of the connecting shaft 11. Guide rails 20 are symmetrically arranged on the side of the first mounting bracket 3 and the second mounting bracket 4 near the mounting plate 12. The guide rails 20 are vertically arranged and their length is greater than the length of the limiting groove 14. The symmetrically arranged guide rails 20 are located on both sides of the connecting shaft 11, and the sliders 19 slide on the guide rails 20. By setting sliders 19 and guide rails, the movement direction of the pressure roller 5 is further limited to prevent the pressure roller 5 from deviating from its intended path.

[0038] The floating device also includes support bolts 21, connectors 22, support rods 23, mounting platforms 24, and hydraulic cylinder push rods 25. Support bolts 21 are installed on the side of the support plate 13. Connectors 22 are fitted onto the support bolts 21, and support rods 23 are installed on the connectors 22. The support rods 23 pass through the mounting platform 24 and connect to the hydraulic cylinder push rods 25. The mounting platform 24 is mounted on the first mounting frame 3 and the second mounting frame 4. The hydraulic cylinder push rods 25 are mounted on the mounting platform 24, and the hydraulic cylinder push rods 25 on both sides move synchronously. The hydraulic cylinder push rods 25 apply downward pressure to the pressure roller 5 to ensure deburring effect and reduce the shaking of the pressure roller 5. Simultaneously, the hydraulic cylinder push rods 25 on both sides, with interconnected hydraulic pressure, ensure that the pressure roller 5 can move vertically up and down, preventing the pressure roller 5 from tilting during the deburring process of the workpiece.

[0039] The adjustment device includes a support bearing 26, a coupling 27, and an adjustment groove 28. The connecting shafts 11 at both ends of the pressure roller 5 are mounted on the support bearings 26, which are located on the side of the mounting plate 12 closest to the pressure roller 5. The first mounting frame 3 has an adjustment groove 28, through which the connecting shafts 11 pass and connect to the coupling 27. The coupling 27 is connected to the output end of the motor 46. The coupling 27 is a ball-cage type constant velocity universal coupling. By using the coupling 27, the pressure roller 5 is still driven by the motor 46 during its up-and-down movement, ensuring the normal rotation of the pressure roller 5.

[0040] The working part also includes an adjusting bracket 29, a balancing cylinder 30, a balancing block 31, a balancing groove 32, an eccentric shaft 33, a mounting hole 34, and an adjusting seat 35. The adjusting bracket 29 is set on one side of the main beam 8, and the balancing cylinder 30 is set on the adjusting bracket 29. The balancing block 31 is set at the output end of the balancing cylinder 30. The moving direction of the balancing block 31 is perpendicular to the direction of the main beam 8. The balancing groove 32 is set vertically on the balancing block 31. The eccentric shaft 33 is set in the balancing groove 32. The upper end of the eccentric shaft 33 is inserted into the mounting hole 34 of the adjusting seat 35. The adjusting seat 35 is set at the lower end of the connecting beam 10. When the angle of the connecting beam 10 needs to be adjusted, the balancing cylinder 30 is activated. The balancing cylinder 30 pushes the balancing block 31 and the eccentric shaft 33 to move. The eccentric shaft 33 pushes the adjusting seat 35 and the connecting beam 10 to rotate, thereby achieving angle adjustment. Through the cooperation of the eccentric shaft 33 and the balancing groove 32, the misalignment between the eccentric shaft 33 and the balancing block 31 during the pushing process is not affected. The eccentric shaft 33 is inserted into the balancing groove 32 and moves up and down along the balancing groove 32 without affecting the up and down movement of the sand belt 7.

[0041] The working part also includes an annular groove 36, a threaded rod 37, a threaded hole 38, a retaining ring 39, a mounting groove 40, and an arc plate 41. A retaining ring 39 is provided at the upper end of the eccentric shaft 33, and a mounting groove 40 is provided at the upper end of the adjusting seat 35. The retaining ring 39 is rotatably positioned within the mounting groove 40. A threaded hole 38 is provided at the upper part of the eccentric shaft 33 within the mounting hole 34. The threaded hole 38 is perpendicular to the eccentric shaft 33 and is connected to the threaded rod 37. The threaded rod 37 passes through the annular groove 36, which is located on the side of the adjusting seat 35. An arc plate 41 is provided on the threaded rod 37, and the arc plate 41 fits against the surface of the adjusting seat 35. The retaining ring 39 and the mounting groove 40 cooperate to prevent the eccentric shaft 33 from falling off. The threaded rod 37 further locks the relative height of the eccentric shaft 33 and facilitates the operator's observation angle. The arc plate 41 blocks the annular groove 36, reducing dust ingress.

[0042] A fixing platform 42 is provided on the lower part of the second mounting bracket 4 on the side away from the pressure roller 5. The fixing platform 42 is connected to the positioning post 44 by a mounting screw 43. The positioning post 44 is set on the positioning seat 45, which is located on the mounting base 1. The mounting screw 43 facilitates positioning adjustment and reduces installation errors.

[0043] Working principle: The workpiece to be deburred is placed on the conveyor belt 2 and moves under the drive of the conveyor belt 2. During the movement, the pressure roller 5 drives the sanding belt 7 to rub against the surface of the workpiece to remove the burrs. When the surface of the workpiece is uneven, the pressure roller 5 moves up and down along the uneven surface. The pressure roller 5 is floating between the first mounting frame 3 and the second mounting frame 4 by setting the compression spring 17 to realize the up and down movement. The hydraulic cylinder push rods 25 on both sides detect the upward movement of the pressure roller 5 and drive the pressure roller 5 to move up and down at the same time. When the angle of the connecting beam 10 needs to be adjusted after the sanding belt 7 is replaced, the balance cylinder 30 is activated. The balance cylinder 30 pushes the balance top block 31 and the eccentric shaft 33 to move. The eccentric shaft 33 pushes the adjusting seat 35 and the connecting beam 10 to rotate.

[0044] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
