Description

Technical Field

[0001] This invention relates to the field of metal parts processing technology, and in particular to a deburring device for metal parts. Background Technology

[0002] Metal sheets are a basic material in industrial manufacturing, construction, and people's livelihood due to their advantages such as convenient forming, strong strength adaptability, and mass production. After metal sheets are processed by cutting, drilling, and stamping, burrs are easily generated at the processing positions, which has a negative impact on production safety, product quality, equipment life and other aspects. Therefore, deburring is an essential post-processing step in the production and processing of metal sheets.

[0003] In the prior art, Chinese utility models such as CN207873889U, CN214080629U, and CN214685788U disclose different deburring devices. These deburring devices process the sheet metal sequentially using a sanding belt and a roller brush. Specifically, the sanding belt is used for rough processing, utilizing its strong cutting force and high efficiency to remove larger particle burrs and impurities from the surface of the sheet metal. The roller brush is responsible for fine grinding of edges and corners and the processing of small particle burrs, thereby improving the high-precision deburring process for metal sheets.

[0004] However, when the aforementioned deburring device is in operation, because the sheet metal is in a horizontal position and its bottom surface is supported by the conveying device, the device can only deburr the top surface of the sheet metal. Therefore, after deburring the top surface of the sheet metal, it is necessary to flip the sheet metal over and process the other side, increasing the workload of workers and reducing processing efficiency. Moreover, the aforementioned roller brush uses rotation and revolution to deburr, resulting in a large overlap in the deburring range, further reducing processing efficiency. Correspondingly, the sanding belt deburrs the sheet metal by moving along its own circumference, and its effective range is significantly different from that of the roller brush, resulting in differences in the degree of deburring on different parts of the sheet metal, reducing the accuracy and uniformity of deburring. In addition, in the aforementioned deburring device, because the sanding belt and roller brush process different parts of the sheet metal at the same time, and the brush is tooled during processing, it is very easy to cause debris to fly. It is necessary to add dust hoods and air pumps, and the working range of the dust hood needs to be large enough to cover the debris scattered, which increases the operating cost of the device.

[0005] Therefore, it is necessary to improve the existing deburring devices for metal sheets. Summary of the Invention

Both the abrasive belt and the roller brush abut against one side of the metal plate on the transmission component.

The two synchronous pulleys are connected by the synchronous belt and are respectively fixedly connected to one end of the mandrel and the output section of the power motor along the same axis. A cover plate is detachably connected to the adjusting frame. The cover plate is sleeved on the other end of the mandrel and fits against one end face of the synchronous belt. The roller brush seal is sleeved on the outside of the mandrel and its two ends are respectively fitted and connected to the cover plate and the adjusting frame.

[0012] Preferably, in order to further improve the deburring accuracy, the connecting frame includes a connecting plate, the connecting plate in the two deburring units of the processing section is vertical and one of the plates is attached to the frame.

[0013] Preferably, in order to facilitate fixing the height of the metal plate and prevent it from moving up and down, the transmission assembly further includes a pressure frame that slides vertically above the movement trajectory of the metal plate.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] like Figures 1-12 As shown, a deburring device for metal parts according to the present invention includes: Rack 1; A transmission component is used to transmit metal sheet 4. In the transmission state, the width direction of metal sheet 4 is vertical, and the length and thickness directions are horizontal. The transmission of metal sheet 4 is parallel to the transmission direction of the transmission component. The transmission component includes a rotating unit 21 and rollers 22 distributed horizontally and rotating around their own axis on the frame 1. The rollers 22 include drive wheels 221 that are spaced apart and whose spacing is less than the length of metal sheet 4. The rotating unit 21 drives the drive wheels 221 to rotate. The deburring assembly includes a deburring unit 5 and a moving unit 6 mounted on a frame 1. The moving unit 6 drives the deburring unit 5 to move circumferentially. The moving trajectory of the deburring unit 5 includes two processing sections that are directly opposite each other on both sides of the transmission assembly and extend vertically between two rollers 22. The deburring units 5 located on the two processing sections are used to deburr both sides of the metal sheet 4 transmitted by the transmission assembly.

[0021] When using the device, the metal plate 4 to be deburred is placed on the transmission component. The transmission component intermittently transmits the metal plate 4, that is, each transmission is a fixed distance and the transmission distance is less than or equal to the deburring range width of the deburring component. During the transmission, the length and thickness of the metal plate 4 are kept horizontal and the width is kept vertical, ensuring that the two surfaces of the metal plate 4 to be processed are in a vertical state.

[0022] When the transmission component is running, the rotating unit 21 drives the drive wheel 221 in the roller 22 to rotate. The drive wheel 221 contacts the bottom of the metal plate 4. The rotation of the drive wheel 221 drives the metal plate 4 to translate. After translating a certain distance, the rotating unit 21 stops running, causing the roller 22 to stop rotating. The metal plate 4 remains stationary. In the stationary state, the deburring component runs, driving the deburring unit 5 to move circumferentially through the moving unit 6, so that the metal plate 4 is located inside the movement trajectory of the deburring unit 5. The movement trajectory of the deburring unit 5 includes two processing sections and two processing steps. The two surfaces of the metal sheet 4 are positioned directly opposite each other and at equal distances. When the deburring unit 5 moves to the processing section, it deburrs the surface of the metal sheet 4 until its working range covers the corresponding area of ​​the metal sheet 4 in the processing section. Then, the transmission component continues to move the metal sheet 4 a fixed distance and stops. The moving unit 6 then moves the deburring unit 5. When the deburring unit 5 moves to the processing section, it processes the two surfaces of the metal sheet 4. This process continues until the working range of the deburring component covers the two surfaces of the metal sheet 4.

[0023] Compared with the prior art, the deburring device of the present invention has the following advantages: First, when the transmission component supports and moves the metal plate 4, the metal plate 4 maintains a vertical angle, which makes it convenient for the moving unit 6 to drive the deburring unit 5 to deburr both sides of the metal plate 4. There is no need to flip the metal plate 4 afterward, which reduces the workload of workers and improves the deburring efficiency. Secondly, when deburring the metal sheet 4, the moving unit 6 drives the deburring unit 5 to perform circumferential movement. When the deburring unit 5 moves to the processing section, it processes the surface of the metal sheet 4. In conjunction with the transmission component, the metal sheet 4 is driven to move intermittently and periodically, which ensures that the deburring component processes both sides of the metal sheet 4 evenly and ensures the deburring accuracy. Finally, during the deburring process of metal sheet 4, since both sides of metal sheet 4 are vertical, the debris generated during deburring will not accumulate on the surface of metal sheet 4. The debris falls off under the action of gravity. Furthermore, the deburring unit 5 only performs deburring when it moves to the processing section. Therefore, workers only need to set up a collection device such as a collection bucket directly below the corresponding position to collect the fallen debris. There is no need to set up suction devices such as dust hoods or air pumps, which reduces the operating cost of the equipment.

[0024] like Figure 7 and Figure 8 As shown, the frame 1 includes a horizontal base 11, which is fixed to the ground. A bottom strip 15 extending in the horizontal direction is fixed above the base 11. The length direction of the bottom strip 15 is parallel to the transmission direction of the transmission component. A foot 151 extending in the vertical direction and distributed along the length direction of the bottom strip 15 is fixedly connected between the bottom strip 15 and the base 11.

[0025] The transmission assembly includes a transmission unit 2 connected to the bottom strip 15. The transmission unit 2 includes a roller 22 and a rotating unit 21. Specifically, the roller 22 rotates around its own axis directly above the bottom strip 15, and the axis of the roller 22 is parallel to the width direction of the bottom strip 15. The roller 22 includes a drive wheel 221 and support wheels 222. The rotating unit 21 is drivenly connected to the drive wheel 221. The interval between two adjacent drive wheels 221 is less than the length of the metal sheet 4. Along the transmission direction of the transmission assembly, several support wheels 22 are provided on both the feed side and the discharge side of the drive wheel 221. 2. The support wheel 222 and the drive wheel 221 are located at the same height and have the same size and specifications, so that when the metal plate 4 is placed on the roller 22 of the transmission component, at least one drive wheel 221 is in contact with the bottom of the metal plate 4. The rotating unit 21 drives each drive wheel 221 to rotate synchronously around its own axis, so that the drive wheel 221 drives the metal plate 4 above to move. In conjunction with the support wheel 222, the bottom of the metal plate 4 is supported, and the metal plate 4 is driven to move along the length direction parallel to the bottom strip 15, that is, the transmission direction of the transmission component.

[0026] A further improvement is that the rotating unit 21 includes a rotating motor 211 fixed on the frame 1 and a rotating wheel 212 fixedly connected to the drive wheel 221 along the same axis. Two adjacent rotating wheels 212 are hinged together by a connecting rod 213, and the output end of the rotating motor 211 is fixedly connected to one of the rotating wheels 212 along the same axis.

[0027] Specifically, such as Figure 3 , Figure 7 and Figure 8 As shown, in the rotating unit 21, the rotating motor 211 is fixed to one side of the bottom bar 15, and its output end is fixedly connected to one of the driving wheels 221 along the coaxial center line. The rotating wheel 212 is located on the other side of the bottom bar 15 and is fixedly connected to each driving wheel 221 along the coaxial center line. The side of the rotating wheel 212 facing away from the driving wheel 221 is hinged through the connecting rod 213, and the hinge position is offset from the axis of the rotating wheel 212.

[0028] With the above structure, when the transmission component needs to move the metal plate 4, the rotary motor 211 is started, which drives one of the drive wheels 221 and the rotating wheel 212 to rotate. The rotating wheel 212 drives the other rotating wheels 212 to rotate through the connecting rod 213, so that the drive wheel 221, which is fixedly connected to the coaxial center line of the other rotating wheels 212, rotates. In this way, all the drive wheels 221 rotate synchronously to drive the metal plate 4 above to translate.

[0029] A further improvement is that a distance sensor 13 is installed on the frame 1 to detect the moving distance of the metal sheet 4.

[0030] Specifically, the distance sensor 13 is located on the upper side of one end of the bottom strip 15 and faces directly above the transmission component. With this design, the distance sensor 13 can detect the moving distance of the metal plate 4, determine the orientation of the metal plate 4, and control the movement of the metal plate 4 in conjunction with the transmission component. This allows the deburring unit 5 and the moving unit 6 to cooperate with each other, ensuring that the deburring range can cover both sides of the metal plate 4, and avoiding excessive overlap of the deburring range of the deburring unit 5 before and after the metal plate 4 moves, which would affect the deburring efficiency.

[0031] A further improvement is that the transmission component has a transmission surface extending along its own transmission direction, the roller 22 is tangent to the lower part of the transmission surface, and the frame 1 includes anti-deviation units 12 disposed on both sides above the transmission surface. The anti-deviation unit 12 includes an anti-deviation roller 121 that is axially vertical and rotates around its own axis. The anti-deviation roller 121 extends along the length direction of the transmission surface and is distributed at intervals less than half the length of the plate. The metal plate 4 located on the transmission surface is attached between the anti-deviation rollers 121 of the two anti-deviation units 12.

[0032] With the above structure, by having the anti-deviation roller 121 adhere to both sides of the metal plate 4, it can be ensured that both sides of the metal plate 4 remain vertical when the transmission component is transmitting the metal plate 4, thus preventing the metal plate 4 from tilting to either side and affecting the deburring accuracy.

[0033] Specifically, such as Figure 7 and Figure 8As shown, when the conveying assembly is conveying the metal sheet 4, the bottom of the metal sheet 4 is on the same horizontal plane as the conveying surface. The frame 1 also includes a vertical plate 16, a connecting frame 17, and a guide frame 18. Anti-deviation rollers 121 are provided on the vertical plate 16, the connecting frame 17, and the guide frame 18 to ensure the distribution of the anti-deviation rollers 121, thereby helping to ensure that the metal sheet 4 does not tilt when it is being conveyed.

[0034] More specifically, there are two vertical plates 16, located at both ends on the same side of the bottom strip 15, with their bottoms fixed to the base 11. The vertical plates 16 are vertically arranged. The connecting frame 17 and the guide frame 18 are distributed between the two vertical plates 16 along the length of the bottom strip 15. The connecting frame 17 is a rectangular frame, with its bottom fixedly connected to the bottom surface of the bottom strip 15. The guide frame 18 is a U-shaped frame, with the guide frame 18 fixedly connected to both sides of the bottom strip 15. Anti-deviation rollers 121 are provided on the inner walls of both sides of the connecting frame 17. Anti-deviation rollers 121 are provided above the side of the guide frame 18 adjacent to the bottom strip 15. Several anti-deviation rollers 121 are distributed at intervals along the length of the bottom strip 15 above the side of the vertical plate 16 adjacent to the bottom strip 15. The anti-deviation rollers 121 on both sides of the bottom strip 15 are combined to form two anti-deviation units 12. Through the interaction of the two anti-deviation units 12, it is ensured that the metal plate 4 maintains a vertical angle on both sides when passing through the connecting frame 17 and the guide frame 18 under the transmission action of the transmission component.

[0035] A further improvement is that the transmission assembly also includes a pressure frame 31 that slides vertically above the movement trajectory of the metal plate 4. A compression spring 32 is provided between the pressure frame 31 and the frame 1. The pressure frame 31 is provided with pressure wheels 33 that are distributed along the transmission direction of the transmission assembly and rotate around their own axis. The axial direction of the pressure wheels 33 is parallel to the axial direction of the rollers 22.

[0036] This design prevents the metal sheet 4 from moving up and down in the height direction during the deburring process, which would affect the processing accuracy. At the same time, the compression spring 32 and the lower pressure roller 33 apply downward pressure to the top of the metal sheet 4, increasing the pressure and friction between the metal sheet 4 and the bottom roller 22, ensuring that the drive wheel 221 can drive the metal sheet 4 to move smoothly when it rotates.

[0037] Specifically, such as Figure 6 and Figure 8As shown, the transmission assembly also includes a pressing unit 3 located directly above the transmission unit 2. The pressing unit 3 includes a pressing frame 31, which is horizontally positioned directly above the bottom strip 15 and along the same length as the bottom strip 15. A sliding rod 34 is fixed above the bottom strip 15, distributed along its length and extending vertically. The sliding rod 34 passes through the top wall of the connecting frame 17 vertically and has a limiting protrusion fixed at its top. The pressing wheel 33 is located directly below the pressing frame 31 and rotates around its own axis on the pressing frame 31. A compression spring 32 is sleeved on the sliding rod 34, with both ends connected to the pressing frame 31 and the inner top wall of the connecting frame 17, respectively, to apply downward pressure to the pressing frame 31.

[0038] A further improvement is that the moving unit 6 includes a closed-loop chain 61 that rotates around its own circumference, a number of sprockets 62 connected by the chain 61, and a drive motor 63 that drives one of the sprockets 62 to rotate around its own axis. The chain 61 is connected to the deburring unit 5. The chain 61 includes two lifting sections 611 that correspond one-to-one with the two processing sections and extend in the vertical direction. The deburring unit 5, which is connected to the two lifting sections 611, moves in the opposite vertical direction.

[0039] Specifically, such as Figure 1 , Figure 7 and Figure 9 As shown, in the moving unit 6, there are two chains 61, which are spaced apart along the length of the bottom bar 15. The chain 61 includes two lifting sections 611 of equal length and an arc section 612 of equal length. The two lifting sections 611 extend vertically and combine with the two arc sections 612 to form an oval-shaped chain 61. The top arc section 612 opens downward and is located above the connecting frame 17, while the bottom arc section 612 opens upward and is located between the bottom bar 15 and the base 11. The sprockets 62 are located at both ends of the inner side of the chain 61 and pass through the chain. 61. Transmission connection: Two sprockets 62 located at the same height are fixedly connected by a coaxial shaft 64. The coaxial shaft 64 is fixedly passed through the sprockets 62 and connected to a rotating bearing 65. The inner ring of the rotating bearing 65 is fixedly connected to the end of the coaxial shaft 64 along the coaxial line, and the outer ring is fixedly connected to a bearing bracket 651. The lower bearing bracket 651 is fixedly connected to the bottom strip 15, and the upper bearing bracket 651 is fixedly connected to the connecting frame 17. The drive motor 63 is fixed above the base 11 and is fixedly connected to one end of the lower coaxial shaft 64 along the coaxial line.

[0040] With the above structure, the drive motor 63 drives the concentric shaft 64 to rotate, so that the two sprockets 62 on the concentric shaft 64 rotate synchronously. With the cooperation of the other two sprockets 62 located above, the drive chain 61 rotates around its own circumference, adjusting the position of the deburring unit 5, so that when the deburring unit 5 moves to the processing section, the metal plate 4 on the transmission component can be deburred on both sides.

[0041] A further improvement is that two deburring units 5 are provided along the circumference of the chain 61, and the interval between the two deburring units 5 is half the circumference of the chain 61.

[0042] like Figure 7 and Figure 9 As shown, when two deburring units 5 are set, during deburring, the two deburring units 5 are located on two processing sections respectively. One moves upward to deburr and the other moves downward to deburr until the two deburring units 5 move to the corresponding positions of the arc section 612 respectively. The deburring units 5 stop running, and the transmission component drives the metal plate 4 to move. In this way, the processing efficiency is improved.

[0043] A further improvement is that the deburring unit 5 includes a connecting frame 51, a telescopic mechanism 52 disposed on the connecting frame 51, an adjusting frame 53 connected to the output end of the telescopic mechanism 52, a roller brush 54 whose axial direction is parallel to the transmission direction of the transmission component, a sanding belt 55 whose width direction is parallel to the transmission direction of the transmission component, and a power mechanism 56 disposed on the adjusting frame 53. The sanding belt 55 rotates on the adjusting frame 53 in its circumferential direction, and the roller brush 54 rotates on the adjusting frame 53 around its own axis. The sanding belt 55 and the roller brush 54 are arranged adjacent to each other in sequence along the rotation direction of the chain 61 and are detachably connected to the output end of the power mechanism 56. The moving direction of the adjusting frame 53 is parallel to the moving trajectory of the deburring unit 5 and perpendicular to the moving direction of the deburring unit 5. Both the sanding belt 55 and the roller brush 54 abut against one side of the metal plate 4 on the transmission component.

[0044] In the deburring unit 5, the power mechanism 56 provides power for the rotation of the sanding belt 55 and the roller brush 54. The sanding belt 55 and the roller brush 54 are distributed along the rotation direction of the chain 61, and the width direction of the sanding belt 55 and the axial direction of the roller brush 54 are parallel to the transmission direction of the transmission assembly, that is, the length direction of the metal sheet 4. Moreover, the two ends of the sanding belt 55 in the width direction and the two ends of the roller brush 54 in the axial direction are flush. Therefore, during deburring, the strong cutting force and high efficiency of the sanding belt 55 are used to remove larger burr particles from the metal sheet 4, achieving rough processing. Then, the roller brush 54 (the surface of the roller brush 54 is densely covered with flexible mousse) removes the tiny soft burrs on the surface of the metal sheet 4, achieving fine processing. The processing range of the sanding belt 55 is the same as that of the roller brush 54, which helps to achieve high-precision and uniform deburring of the metal sheet 4. Furthermore, the sanding belt 55 and the roller brush 54 are detachably connected to the output end of the power mechanism 56, which facilitates the replacement of the sanding belt 55 and the roller brush 54 after a period of use to ensure the quality of subsequent deburring. In addition, when the deburring unit 5 is running, the generated debris is mainly concentrated directly below the movement trajectory of the deburring unit 5. Therefore, it is only necessary to place a collection bucket directly below the movement trajectory of the deburring unit 5 to easily collect the generated debris. There is no need to install a dust collection hood or other dust collection device, which further reduces the operating cost of the device and reduces the workload of workers collecting debris.

[0045] During deburring, the telescopic mechanism 52 drives the adjusting frame 53 to move closer to the metal plate 4, so that the sanding belt 55 and the roller brush 54 can remove the burrs on the metal plate 4. When the moving unit 6 drives the deburring unit 5 to move to other positions, the telescopic mechanism 52 drives the adjusting frame 53 to move away from the metal plate 4, so as to avoid the sanding belt 55 and the roller brush 54 from contacting the frame 1 and the transmission components and causing wear.

[0046] A further improvement is that the power mechanism 56 includes a power motor 561, a drive roller 562, a driven roller 563, a spindle 564, a synchronous belt 565, and two synchronous pulleys 566. The power motor 561 is fixed on the adjusting frame 53 and its output end is fixedly connected to the drive roller 562. The drive roller 562 and the driven roller 563 are connected by a sanding belt 55. The two synchronous pulleys 566 are connected by a synchronous belt 565 and are respectively fixedly connected to one end of the spindle 564 and the output section of the power motor 561 along the same axis. A cover plate 57 is detachably connected to the adjusting frame 53. The cover plate 57 is sleeved on the other end of the spindle 564 and fits against one end face of the synchronous belt 565. The roller brush 54 is sealed on the outside of the spindle 564 and its two ends are respectively fitted and connected to the cover plate 57 and the adjusting frame 53.

[0047] With the above structure, the sanding belt 55 and the roller brush 54 are detachably connected to the output end of the power mechanism 56, which facilitates the replacement of the sanding belt 55 and the roller brush 54 and ensures long-term stable deburring quality of the metal sheet 4.

[0048] Specifically, such as Figures 10-12 As shown, in the deburring unit 5, the connecting frame 51 includes a connecting plate 511, a first folding plate 512, and a second folding plate 513. Both the first folding plate 512 and the second folding plate 513 are U-shaped plates with the U-shaped openings facing the same direction. The second folding plate 513 is integrally connected to the back of the U-shaped opening of the first folding plate 512. The connecting plate 511 is located at both ends of the first folding plate 512. Connecting rods 5121 are fixed on both sides of the first folding plate 512. The end of the connecting rod 5121 away from the first folding plate 512 is connected to the chain 61.

[0049] The telescopic mechanism 52 includes an adjusting motor 521 fixed inside the second folding plate 513. An adjusting screw 522 is fixedly connected to the output end of the adjusting motor 521 along the coaxial centerline. An adjusting sleeve 523 is threadedly connected to the adjusting screw 522. The adjusting sleeve 523 slides through the first folding plate 512 and is fixedly connected to the adjusting frame 53. The moving direction of the adjusting sleeve 523 is parallel to the moving trajectory of the deburring unit 5 and perpendicular to the moving direction of the deburring unit 5. The power mechanism 56 is mounted on the adjusting frame 53.

[0050] When the telescopic mechanism 52 is running, the adjusting motor 521 drives the adjusting screw 522 to rotate, which acts on the adjusting screw sleeve 523 through the thread, causing the adjusting screw sleeve 523 to drive the first folding plate 512 to move axially along the adjusting screw 522. This, in turn, drives the power mechanism 56 set on the adjusting frame 53 and the sanding belt 55 and roller brush 54 connected to the output end of the power mechanism 56 to move, so that the deburring unit 5 can deburr the metal sheet 4 in the processing section, while in other positions, it maintains a certain gap with the frame 1 and the transmission components.

[0051] More specifically, the adjustment frame 53 is a U-shaped frame, and the orientation of its U-shaped opening is consistent with the orientation of the U-shaped opening of the first folding plate 512. One end of the adjustment frame 53 is provided with a notch, which is adapted to the shape of the cover plate 57. The two sides of the cover plate 57 and the inner walls on both sides of the notch are detachably and fixedly connected by bolts 571.

[0052] In the power mechanism 56, the power motor 561 is fixed to the other side of the adjusting frame 53, and its output end is fixedly connected to one of the synchronous pulleys 566 along the same axis. The synchronous pulley 566 is connected to the other synchronous pulley 566 via a synchronous belt 565. The driving roller 562 and the driven roller 563 rotate around their own axes between the cover plate 57 and the adjusting frame 53. The spindle 564 rotates around its own axis between the cover plate 57 and the adjusting frame 53. The ends of the spindle 564, the driving roller 562, and the driven roller 563 away from the notch are all connected to the support bearing 567 along the same axis. The outer ring of the support bearing 567 is connected to the adjusting frame 566. The frame 53 is fixedly connected, and the cover plate 57 is provided with three circular through holes, which are respectively sealed and fitted on the ends of the spindle 564, the driving roller 562 and the driven roller 563 near the notch. In this way, the spindle 564, the driving roller 562 and the driven roller 563 are supported to rotate stably around their own axis. The sanding belt 55 is tensioned and fitted on the outside of the driving roller 562 and the driven roller 563. The output ends of the driving roller 562 and the power motor 561 are respectively fixedly connected to the two coaxial centers of one of the synchronous pulleys 566. The other synchronous pulley 566 is fixedly connected to the coaxial center of the spindle 564. The roller brush 54 is sealed and fitted on the outside of the spindle 564.

[0053] With the above structure, after the power motor 561 starts, it drives the active roller 562 to rotate. With the cooperation of the driven roller 563, it can drive the sand belt 55 to rotate along its own circumference. At the same time, the power motor 561 drives one of the synchronous pulleys 566 to rotate, and drives the other synchronous pulley 566 to rotate through the synchronous belt 565. This causes the spindle 564, which is coaxially connected to the synchronous pulley 566, to rotate, thereby driving the roller brush 54, which is sealed outside the spindle 564, to rotate.

[0054] The mandrel 564 includes a round shaft and a protruding key integrally formed outside the round shaft. The center of the roller brush 54 is provided with a round hole adapted to the round shaft and a groove adapted to the protruding key. The round hole and the groove are combined to form an assembly through hole adapted to the mandrel 564. In this way, the roller brush 54 can be sealed and fitted outside the mandrel 564. After the mandrel 564 rotates, it can drive the roller brush 54 to rotate synchronously.

[0055] A further improvement is that the connecting frame 51 includes a connecting plate 511, which is located in the two deburring units 5 of the processing section. The connecting plate 511 has a vertical plate surface and one of the plate surfaces is in close contact with the frame 1.

[0056] Specifically, such as Figure 6As shown, when moving to the processing section, the connecting plate 511 of the connecting frame 51 is in contact with the guide frame 18. The contact surfaces of the connecting plate 511 and the guide frame 18 are vertical. This ensures that during the processing section, the telescopic mechanism 52 drives the adjusting frame 53 to move horizontally along the thickness direction of the metal plate 4 on the transmission assembly. In the deburring unit 5, the axial direction of the roller brush 54 and the width direction of the sand belt 55 are both horizontal, thereby ensuring the deburring accuracy of the deburring unit 5 on the metal plate 4.

[0057] Since the metal sheet 4 has a certain weight, guide components 8 are provided at both the inlet and outlet ends of the conveying assembly to facilitate loading and unloading. Figures 1-5 and Figure 7 As shown, the material guiding assembly 8 includes a pallet 81, which rotates above the bottom strip 15 with its rotation axis parallel to the length direction of the bottom strip 15. The pallet 81 is connected to a locking assembly, which is used to lock the pallet 81 in the material guiding position. In the material guiding position, the pallet 81 is located above the bottom strip 15 and directly opposite the vertical plate 16. The pallet 81 is in a vertical angle. The locking assembly includes a locking sleeve 83 fixed to the back of the pallet 81. An axially vertical fixing sleeve 14 is fixed to the lower side of the bottom strip 15. The locking sleeve 83 and the fixing sleeve 14 are engaged by a locking pin 84, and the locking pin 84 is threadedly connected to the fixing sleeve 14.

[0058] After adopting the above method, remove the locking pin 84 from the fixing sleeve 14 to facilitate the locking of the tray 81. Rotate the tray 81 to the tilt angle to facilitate placing the metal sheet 4 to be processed on the tray 81. Rotate the tray 81 upward so that the metal sheet 4 rotates upward and finally the bottom contacts the roller 22. Alternatively, place the deburred metal sheet 4 against the tray 81 and rotate the tray 81 downward to facilitate the removal of the deburred metal sheet 4.

[0059] When the pallet 81 is positioned at the material guide station, the locking pin 84 passes through the locking sleeve 83 and is threadedly connected to the inner wall of the fixing sleeve 14, thereby locking the position of the pallet 81 and preventing the metal plate 4 from falling off the top of the transmission assembly.

[0060] A further improvement is that the pallet 81 is also densely covered with balls 82. In the material guiding station, the balls 82 are located between the vertical plate 16 and the pallet 81. By setting the balls 82, the wear on the surface of the metal sheet 4 can be reduced.

[0061] A further improvement is that a baffle 811 extending parallel to the transmission direction of the transmission assembly is fixed on the side of the pallet 81 away from its rotation axis. The baffle 811 and the ball bearing 82 are located on the same side of the pallet 81. The two ends of the baffle 811 are integrally connected to the blocks 812 facing the rotation axis of the pallet 81. The spacing of the blocks 812 is consistent with the length of the metal plate 4. In this way, when the pallet 81 rotates downward, the horizontal position of the metal plate 4 can be limited by the baffle 811 and the blocks 812. During feeding, one side of the metal plate 4 is in contact with the baffle 811 and the blocks 812, thereby limiting the position of the metal plate 4. When the metal plate 4 rotates upward with the pallet 81, the metal plate 4 slides downward under the action of the ball bearing 82 until it is in contact with the roller 22 at the feeding end of the transmission assembly. Furthermore, at the material guiding station, the ball bearing 82 and the anti-deviation roller 121 on the vertical plate 16 are respectively attached to the two sides of the metal sheet 4 to achieve stable transmission of the metal sheet 4 and prevent the metal sheet 4 from shifting in the thickness direction during transmission.

[0062] A further improvement is that a lifting component 7 is provided at the discharge end of the transmission component. When the metal plate 4 moves to the discharge end of the transmission component, the lifting component 7 lifts the metal plate 4 until the top of the metal plate 4 is in contact with the baffle 811 and baffle 812 on the lower support plate 81 of the guide station.

[0063] With the above design, after deburring, the metal sheet 4 is moved to its discharge end by the transmission component. The lifting component 7 lifts the metal sheet 4 so that it is separated from the roller 22. The operator then releases the locking pin 84 from the fixing sleeve 14, causing the pallet 81 to rotate slowly downwards. The metal sheet 4 rotates downwards with the pallet 81. The stop bar 811 and the stop block 812 limit the horizontal position of the metal sheet 4 and prevent the pallet 81 from tilting downwards. This prevents the metal sheet 4 from falling off the pallet 81, making it easier for the operator to safely unload the deburred metal sheet 4.

[0064] More specifically, the lifting assembly 7 includes two hydraulic cylinders 71 distributed along the length of the base strip 15. The cylinder barrel of the hydraulic cylinder 71 is vertical and fixed above the base 11. The piston rod of the hydraulic cylinder 71 is sealed through the base strip 15 and a horizontal lifting plate 72 is fixedly connected to its top. With this design, the lifting plate 72 is raised and lowered by controlling the hydraulic cylinder 71, which facilitates lifting the metal plate 4 output from the output end of the transmission assembly and detaching it from the roller 22. After the support plate 81 rotates downward, the metal plate 4 can rotate downward with the support plate 81.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
