Description

Technical Field

[0001] This utility model relates to the field of metal profile processing, specifically a high-efficiency deburring equipment. Background Technology

[0002] Burrs on mechanical parts are caused by various factors, including plastic deformation during machining, flash from casting and forging, and residual material from welding extrusion. With increasing industrialization and automation, particularly in the aerospace and instrumentation sectors, the demand for precision in manufacturing mechanical parts and the miniaturization of mechanisms have made the harmfulness of burrs particularly apparent. This has led to widespread attention and research into the formation mechanism and removal methods of burrs.

[0003] Modern deburring methods commonly include mechanical methods, which use industrial robots to hold rotating wire brushes or grinding wheels and use the joints of the robot arms to grind away the burrs; vibration methods, which use the rapid reciprocating vibration of a container to remove burrs by friction between the parts and the medium; thermal methods, which involve sealing the parts in a container filled with a high-pressure mixture of combustible gas and oxygen and using high temperatures to pulverize the burrs; and electrochemical methods, which use electrochemical reactions to dissolve the metal material from the parts into an electrolyte, thereby removing the burrs.

[0004] Mechanical deburring is quite common; however, most existing mechanical deburring equipment can only process sheet metal workpieces. When faced with cylindrical tubes or bars, the clamping is unstable, the grinding efficiency is low, and deformation is easy to occur. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a high-efficiency deburring equipment to solve the technical problems that most existing mechanical deburring equipment can only process sheet metal workpieces, while it has problems such as unstable clamping, low grinding efficiency and easy deformation when dealing with cylindrical tubes or bars.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency deburring device, comprising a base, with multiple sets of guide rails fixedly connected to the upper surface of the base, the upper surface of each set of guide rails being slidably connected to the inner wall of a support slider, the outer wall of the support slider being fixedly connected to the interior of a first connecting bracket, the first connecting bracket having multiple connection points fixedly connected to multiple sets of fixed seats, a first motor being fixedly connected to the inner wall of one set of fixed seats, the output end of the first motor being fixedly connected to a transmission wheel through a tension wheel, a chain drive belt being slidably connected to the outer wall of the transmission wheel, a connecting block being movably connected inside the chain drive belt, a limit frame being fixedly connected to the connecting block, and multiple sets of rollers being fixedly connected inside the limit frame.

[0007] By adopting the above technical solution, a guide rail is installed on the base. The first connecting bracket slides on the guide rail through the bracket slider, pushing the first connecting bracket to adjust the distance between it and the second connecting bracket, and fixing the slidable first connecting bracket. The first motor and two sets of second motors on the first and second connecting brackets start simultaneously. The output end of the first motor is fixedly connected to a tension wheel through the first protective plate, and the other end of the tension wheel is fixedly connected to a flexible grinding head. At the same time, the tension wheel connected to the motor is rotatably connected to another set of tension wheels through the first transmission belt. The other set of tension wheels is also fixedly connected to a set of flexible grinding heads. When the first motor drives the flexible grinding head to rotate, the other set of flexible grinding heads rotates accordingly.

[0008] Furthermore, a second motor is fixedly connected inside the fixed base, and a transmission wheel is fixedly connected to the output end of the second motor through the tension wheel.

[0009] By adopting the above technical solution, a set of tensioning wheels is fixedly connected to the output end of the second motor, and a transmission wheel is fixedly connected to the other end of the set of tensioning wheels. At the same time, the set of tensioning wheels is connected to another set of tensioning wheels through the second transmission belt, and the set of tensioning wheels is also fixedly connected to the transmission wheel. When the second motor drives the set of transmission wheel to rotate, the other set of transmission wheel rotates synchronously.

[0010] Furthermore, a frame is fixedly connected to the upper surface of the base, and multiple sets of springs are fixedly connected to the outside of the frame. The other end of every two sets of springs is fixedly connected to a set of crossbars. The crossbars are all connected through a pressure plate. A pressure band is slidably connected to the outer wall of the pressure plate. A connecting slider is slidably connected to the outside of the frame. Each set of connecting sliders is fixedly connected to one end of the crossbar.

[0011] By adopting the above technical solution, two sets of crossbars are fixedly connected to the frame by four sets of springs. Both sets of crossbars are connected through the pressure plate. A rubber pressure band is slidably connected to the surface of the pressure plate. Connecting sliders are fixedly connected to both sides of the crossbars. The connecting sliders slide up and down on the frame. When the limiting frame moves with the workpiece, the surface of the workpiece passively contacts the pressure band. The four sets of springs are passively compressed, so that the pressure band and the limiting frame cooperate to press the workpiece.

[0012] Furthermore, a first protective plate is fixedly connected to one end of the first connecting bracket, and the other end of the first protective plate is penetrated by the output end of the first motor and fixedly connected to the first motor. A second protective plate is fixedly connected to one end of the first connecting bracket, and the other end of the second protective plate is penetrated by the output end of the second motor and fixedly connected to the second motor.

[0013] By adopting the above technical solution, a tensioning wheel is fixedly connected to the output end of the first motor through the first protective plate, and a set of tensioning wheels is fixedly connected to the output end of the second motor through the second protective plate.

[0014] Furthermore, the first motor is rotatably connected to the tension wheel outside the tension wheel, and a first transmission belt is rotatably connected to the other end of the first transmission belt. The second motor is rotatably connected to the outer wall of the tension wheel, and a second transmission belt is rotatably connected to the other end of the second transmission belt.

[0015] By adopting the above technical solution, the tensioning wheel connected to the first motor is rotatably connected to another set of tensioning wheels through the first transmission belt, and the other set of tensioning wheels is also fixedly connected to a set of flexible grinding heads. The output end of the second motor is connected to the tensioning wheel and is driven to another set of tensioning wheels through the second transmission belt, and this set of tensioning wheels is fixedly connected to the transmission wheel disc.

[0016] Furthermore, positioning frames are fixedly connected to the outer walls of both the first and second connecting brackets, and the positioning frames serve to limit the length of the workpiece.

[0017] By adopting the above technical solution, positioning frames are fixedly connected to the first connecting bracket and the second connecting bracket at the feed inlet of the equipment. When the limiting frame and the positioning frame coincide, the pipe or bar material to be deburred can be placed in. The positioning frame ensures the accuracy of the placement position of the workpiece to be deburred.

[0018] In summary, the present invention has the following main advantages:

[0019] The relative position of the first connecting bracket is adjusted by the guide rail mounted on the base to flexibly adapt to the processing needs of pipes or bars of different lengths. The first motor drives two sets of flexible grinding heads and the second motor drives the transmission wheel, so that the two sets of flexible grinding heads and the chain drive belt work together to achieve efficient and continuous grinding. The precise alignment of the positioning frame and the limit frame ensures accurate initial positioning of the workpiece, while the elastic structure of the spring pressure plate and the pressure belt, together with the rollers in the limit frame, keeps the workpiece under appropriate pressure and rotates at a uniform speed during the conveying process, which not only avoids deformation but also improves the uniformity of grinding. The two-stage flexible grinding heads complete the rough and fine grinding in steps, which significantly improves the burr removal effect. The end of the chain drive belt engages with the connecting block through the U-shaped groove of the transmission wheel to realize the stable rotation of the limit frame. Combined with gravity automatic unloading, the intensity of manual intervention is greatly reduced. Attached Figure Description

The upper end face of each set of guide rails 101 is slidably connected to the inner wall of the bracket slider 301.

[0029] The base 1 is equipped with a guide rail 101. The first connecting bracket 3 slides on the guide rail 101 via the bracket slider 301, which pushes the first connecting bracket 3 to adjust the distance between it and the second connecting bracket 6, and fixes the slid-on first connecting bracket 3.

[0030] Furthermore, the outer wall of the bracket slider 301 is fixedly connected to the inside of the first connecting bracket 3. The first connecting bracket 3 has multiple connection points that are fixedly connected to multiple sets of fixed seats 302. The inner wall of one set of fixed seats 302 is fixedly connected to a first motor 401. The output end of the first motor 401 passes through the tension wheel and is fixedly connected to a transmission wheel 406. The outer wall of the transmission wheel 406 is slidably connected to a chain transmission belt 405. The chain transmission belt 405 is movably connected to a connecting block 501. The connecting block 501 is fixedly connected to a limit frame 5. The limit frame 5 is fixedly connected to multiple sets of rollers 502.

[0031] This allows the first motor 401 and two sets of second motors 402 on the first connecting bracket 3 and the second connecting bracket 6 to start simultaneously. The output end of the first motor 401 is fixedly connected to a tensioning wheel through the first protective plate 303, and the other end of the tensioning wheel is fixedly connected to a flexible grinding head 407. At the same time, the tensioning wheel connected to the motor is rotatably connected to another set of tensioning wheels through the first transmission belt 403, and the other set of tensioning wheels is also fixedly connected to a set of flexible grinding heads 407. When the first motor 401 drives the flexible grinding head 407 to rotate, the other set of flexible grinding heads 407 rotates accordingly.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The second motor 402 is fixedly connected inside the fixed base 302, and the output end of the second motor 402 is fixedly connected to the transmission wheel 406 through the tension wheel;

[0034] Please see Figure 1 and Figure 2 A frame 2 is fixedly connected to the upper surface of the base 1. Multiple sets of springs 201 are fixedly connected to the outside of the frame 2. The other end of every two sets of springs 201 is fixedly connected to a set of crossbars 205. The crossbars 205 are all connected through the pressure plate 204. A pressure band 203 is slidably connected to the outer wall of the pressure plate 204. A connecting slider 202 is slidably connected to the outside of the frame 2. Each set of connecting sliders 202 is fixedly connected to one end of the crossbar 205.

[0035] The frame 2 is fixedly connected to two sets of crossbars 205 by four sets of springs 201. Both sets of crossbars 205 are connected to the pressure plate 204. The surface of the pressure plate 204 is slidably connected to a rubber pressure band 203. Connecting sliders 202 are fixedly connected to both sides of the crossbars 205. The connecting sliders 202 slide up and down on the frame 2. When the limiting frame 5 moves with the workpiece, the surface of the workpiece passively contacts the pressure band 203. The four sets of springs 201 are passively compressed, so that the pressure band 203 and the limiting frame 5 cooperate to press the workpiece.

[0036] Please see Figure 2 , Figure 3 and Figure 4The first connecting bracket 3 has a first protective plate 303 fixedly connected to one end of its connecting end, and the other end of the first protective plate 303 is penetrated by the output end of the first motor 401 and fixedly connected to the first motor 401. The first connecting bracket 3 has a second protective plate 304 fixedly connected to one end of its connecting end, and the other end of the second protective plate 304 is penetrated by the output end of the second motor 402 and fixedly connected to the second motor 402.

[0037] The output end of the first motor 401 is fixedly connected to a tensioning wheel through the first protective plate 303, while the output end of the second motor 402 is also fixedly connected to a set of tensioning wheels through the second protective plate 304.

[0038] Please see Figure 2 , Figure 3 and Figure 4 The first motor 401 is rotatably connected to the tension wheel and a first transmission belt 403. The other end of the first transmission belt 403 is also rotatably connected to a set of tension wheels. The second motor 402 is rotatably connected to the outer wall of the tension wheel and a second transmission belt 404. The other end of the second transmission belt 404 is also rotatably connected to a set of tension wheels.

[0039] The tensioning wheel connected to the first motor 401 is rotatably connected to another set of tensioning wheels via the first transmission belt 403. The other set of tensioning wheels is also fixedly connected to a set of flexible grinding heads 407. The output end of the second motor 402 is connected to the tensioning wheel via the second transmission belt 404 and is connected to another set of tensioning wheels. This set of tensioning wheels is fixedly connected to the transmission wheel disc 406.

[0040] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The first connecting bracket 3 and the second connecting bracket 6 are both fixedly connected to the outer walls of the positioning frame 305, which serves to limit the length of the workpiece.

[0041] Positioning frames 305 are fixedly connected to the first connecting bracket 3 and the second connecting bracket 6 at the feed inlet of the equipment. When the limiting frame 5 coincides with the positioning frame 305, the pipe or bar material to be deburred can be placed in it. The positioning frame 305 ensures the accuracy of the placement position of the workpiece to be deburred.

[0042] The working principle of this utility model is as follows: When in use, the length of the pipe or bar is determined, a guide rail 101 is installed on the base 1, the first connecting bracket 3 slides on the guide rail 101 through the bracket slider 301, pushes the first connecting bracket 3 to adjust the distance between it and the second connecting bracket 6, and fixes the slid first connecting bracket 3.

[0043] When the power is turned on, the first motor 401 and two sets of second motors 402 on the first connecting bracket 3 and the second connecting bracket 6 start simultaneously. The output end of the first motor 401 is fixedly connected to a tension wheel through the first protective plate 303, and the other end of the tension wheel is fixedly connected to a flexible grinding head 407. At the same time, the tension wheel connected to the first motor 401 is rotatably connected to another set of tension wheels through the first transmission belt 403. The other set of tension wheels is also fixedly connected to a set of flexible grinding heads 407. When the first motor 401 drives the flexible grinding head 407 to rotate, the other set of flexible grinding heads 407 rotates accordingly.

[0044] The output end of the second motor 402 also passes through the second protective plate 304 and is fixedly connected to a set of tensioning wheels. The other end of the set of tensioning wheels is fixedly connected to a transmission wheel 406. At the same time, the set of tensioning wheels is connected to another set of tensioning wheels through the second transmission belt 404. The set of tensioning wheels is also fixedly connected to the transmission wheel 406. When the second motor 402 drives the set of transmission wheel 406 to rotate, the other set of transmission wheel 406 rotates synchronously.

[0045] The two sets of transmission wheel discs 406 are also connected by a chain transmission belt 405. The chain transmission belt 405 is equipped with a limit frame 5 by multiple sets of connecting blocks 501. Multiple sets of U-shaped grooves are opened on both ends of the transmission wheel disc 406. The U-shaped grooves and the connecting blocks 501 mesh with each other to ensure that the chain transmission belt 405 can smoothly drive the limit frame 5 to rotate between the two sets of transmission wheel discs 406.

[0046] Positioning frames 305 are fixedly connected to the first connecting bracket 3 and the second connecting bracket 6 at the feed inlet of the equipment. When the limiting frame 5 coincides with the positioning frame 305, the pipe or bar material to be deburred can be placed in. The positioning frame 305 ensures the accuracy of the placement of the workpiece to be deburred. The limiting frame 5 then carries the workpiece forward. Two sets of crossbars 205 are fixedly connected to the frame 2 by four sets of springs 201. Both sets of crossbars 205 are connected through the pressure plate 204. A rubber pressure band 20 is slidably connected to the surface of the pressure plate 204. 3. Connecting sliders 202 are fixedly connected to both sides of the crossbar 205. The connecting sliders 202 slide up and down on the frame 2. When the limiting frame 5 moves with the workpiece, the surface of the workpiece passively contacts the pressing band 203. The four sets of springs 201 are passively compressed, so that the pressing band 203 and the limiting frame 5 cooperate to press the workpiece. At the same time, the limiting frame 5 is equipped with multiple sets of rollers 502, so that the workpiece rotates slowly when it is pressed and moves forward. The rotation makes the cylindrical workpiece more evenly stressed, ensuring that the workpiece is cleaned more thoroughly without deformation.

[0047] The workpiece rotates and passes through the first set of flexible grinding heads 407, which completes the rough cleaning of large burrs and rough edges. The second set of flexible grinding heads 407 further polishes the small burrs on the workpiece. When the workpiece is polished and moves to the end of the chain drive belt 405, it loses the pressure of the clamping belt 203. When the chain drive belt 405 carries the limit frame 5 through the transmission wheel 406, the limit frame 5 flips and the workpiece automatically falls into the collection container.
