Description

Technical Field

[0001] The present invention relates to the technical field of deburring equipment, and particularly to a deburring and leveling equipment for a heat exchanger flange plate after laser cutting processing. Background Art

[0002] Deburring and leveling equipment is a special equipment used to remove burrs on the surface or edge of a workpiece and make the surface of the workpiece smoother and flatter. Such equipment is widely used in fields such as metal processing, plastic products, and precision parts manufacturing, and can significantly improve product quality and production efficiency;

[0003] For example, the prior art publication number CN113245943B discloses a deburring system and method for an elevator guide rail; this technology includes a rotating bracket, a central shaft, and a base. The base is provided with a central sleeve, the central shaft is rotatably connected to the central sleeve, one end of which is hinged to the rotating bracket through a bracket rotating shaft. The rotating bracket is provided with a cylindrical grinding wheel, a stepped grinding wheel, and a grinding wheel motor for driving the cylindrical grinding wheel and the stepped grinding wheel to rotate. The axes of the cylindrical grinding wheel and the stepped grinding wheel are both parallel to the bracket rotating shaft, and the stepped grinding wheel includes a small grinding wheel and a large grinding wheel whose outer diameters match the side part of the elevator guide rail; the central shafts of the cylindrical grinding wheel and the stepped grinding wheel are both connected to synchronously rotating belt pulleys, and the two belt pulleys are connected to a sand belt. The above invention only realizes the deburring operation on the end of the entire elevator guide rail through two grinding wheels, enabling the product to complete the deburring operation on one end of the entire end with one clamping, improving the processing efficiency; when the grinding wheel wears, the grinding depth can still be ensured to remain unchanged without adjusting the tool compensation; at the same time, the axial position accuracy of the elevator guide rail is reduced;

[0004] When the prior art deburrs a heat exchanger flange plate, it grinds the surface of the part through two grinding rollers to scrape off the burrs on the part. When facing a part with a stepped protrusion, only grinding the part through the grinding rollers will result in machining dead corners, and the corner positions cannot be processed, resulting in uneven quality of the parts. And since the flange plate is fixed by bolts during installation, there is a circle of mounting holes around it. When the prior art grinding rollers sweep over the mounting holes, some burr waste materials are not separated from the flange plate and will fold on the inner wall of the mounting holes, making the burr waste materials at this place unable to be effectively removed. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title, but such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] The present invention provides a deburring and leveling device for a heat exchanger flange plate after laser cutting processing, which can solve the problem that the existing deburring device has machining dead corners. The specific solution is as follows:

[0007] A deburring and leveling device for a heat exchanger flange plate after laser cutting processing includes a device body and a conveyor belt for conveying parts to the processing area inside the device body. A first grinding member is arranged in the processing area. After the parts are conveyed into the device body, the end faces of the parts are ground by the first grinding member. The vertical plane passing through the central axis of the part is defined as the P1 plane, and a second grinding member is also arranged in the processing area;

[0008] In the grinding state: The grinding area of the first grinding member always adheres to the lateral projection boundary line of the part, and the central axes of the first grinding member and the part are both on the P1 plane. The first grinding member and the part perform a relative rotary cutting motion. The second grinding member contacts the edge of the mounting hole of the part. The second grinding member is installed outside the mounting hole of the part through a rotating seat. The rotating seat is relatively fixed to the part, and the grinding area of the second grinding member can rotate around the central axis of the mounting hole.

[0009] Preferably, the first grinding member performs a stepped motion along the stepped lateral projection boundary line of the part on the P1 plane through a stepped motion component, and the part rotates along its own central axis.

[0010] Preferably, the first grinding member rotates along the central axis of the part through a rotating component, and the part is placed relatively fixedly in the processing area.

[0011] Preferably, it further includes:

[0012] A clamping column, and clamping columns that can extend are provided on both sides of the bottom of the clamping column;

[0013] A first two-axis moving member for driving the first grinding member to move vertically and horizontally on the P1 plane. The first two-axis moving member includes a first telescopic rod and a second telescopic rod connected to the side of the telescopic end of the first telescopic rod. The end of the second telescopic rod is connected to the first grinding member.

[0014] Preferably, it further includes:

[0015] A second motor, and the clamping column rotates by itself through the second motor to make a relative rotary cutting motion between the part and the first grinding member. The top of the first telescopic rod is relatively fixed to the device body.

[0016] Preferably, it further includes:

[0017] A toothed ring, which is rotatably installed in the processing area of the device body. The toothed ring rotates driven by a first motor. The first grinding member and the first two-axis moving member are installed under the toothed ring and rotate synchronously with the toothed ring to make a relative rotary cutting motion between the part and the first grinding member.

[0018] Preferably, it further includes:

[0019] A rotating seat, which is of an annular structure and concentric with the mounting hole, and is installed on the outer wall of the clamping column;

[0020] A rotating block, with a fifth motor connected to its top;

[0021] A second two-axis moving member, installed under the rotating block. The second two-axis moving member includes a seventh telescopic rod. A side of the bottom telescopic end of the seventh telescopic rod is connected to an eighth telescopic rod, and an end of the eighth telescopic rod is connected to the second grinding member;

[0022] Wherein, the fifth motor drives the rotating block together with the second grinding member to rotate along the central axis of the part mounting hole to grind the inner wall of the part mounting hole.

[0023] Preferably, a grasping assembly is installed in the processing area. The grasping assembly is used to clamp the part to be processed to the positions corresponding to the first grinding member and the second grinding member. The grasping assembly includes:

[0024] Clamping rods, there are two of them, located on both sides of the clamping column. One end of the clamping rod close to the clamping column is connected to a third gear. A second rack is arranged on one side of the third gear. The second rack meshes with the third gear. The top end of the second rack is fixedly connected to a fourth telescopic rod. The fourth telescopic rod is fixedly installed at both ends of the top of the clamping column. When the fourth telescopic rod drives the second rack to move up and down, under the meshing action of the second rack and the third gear, the angle adjustment of the clamping rod is realized.

[0025] Preferably, a fifth telescopic rod is connected to the bottom of the end of the clamping rod far from the clamping column. The bottom of the fifth telescopic rod is connected to a moving frame. One end of the moving frame is connected to a fourth motor. The output end of the fourth motor is connected to a fourth gear. A fifth gear is arranged below the fourth gear. The fifth gear meshes with the fourth gear. The middle of the fifth gear is fixedly connected through a rotating shaft. When the fourth gear rotates, it can drive the fifth gear and the rotating shaft to rotate.

[0026] Preferably, the rotating shaft is slidably connected to the bottom of the moving frame. One end of the moving frame is fixedly connected to a sixth telescopic rod. The telescopic end of the sixth telescopic rod is rotatably connected to one end of the rotating shaft. A second spring and a rotating ring are arranged between the fifth gear and the moving frame. The rotating ring is rotatably connected to the outer wall of the rotating shaft. The rotating ring is connected to the moving frame through the second spring. When the sixth telescopic rod drives the rotating shaft to move towards the part, the part can be clamped.

[0027] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects:

[0028] 1. By setting that the first grinding piece can move along the surface of the stepped part to grind the burrs on the part surface, the defect that the deburring and leveling equipment in the prior art cannot grind the burrs on the surface of the stepped part is solved.

[0029] 2. By setting that the second grinding piece can further grind the burrs at the corners of the mounting holes on the part, the problem that some burrs will be folded inside the mounting holes during the overall grinding of the part by the deburring and leveling equipment in the prior art, resulting in incomplete grinding, is solved, so as to effectively remove the burrs inside the mounting holes.

[0030] 3. By setting the clamping rod and the rotating shaft, the part located on the conveyor belt can be picked up, so that the part can be relatively fixed with the clamping column, which is convenient for subsequent grinding treatment. Moreover, the clamping rod and the rotating shaft can also flip the orientation of the part, so that the first grinding piece and the second grinding piece can grind the two sides of the part respectively.

[0031] 4. By setting the sliding piece and the sliding rail, the clamping column can be far away from the first grinding piece. When the first grinding piece gradually deviates from the part, the pushing surface on the first grinding piece can push the burr waste on the part, so that the burr waste can be pushed to one side of the part, and the burr waste is discharged directionally.

[0032] Other features and advantages of the present invention will be described in the subsequent specific embodiments. Moreover, some of them will become obvious from the description of the specification, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be achieved and obtained through the structure specifically pointed out in the written specification and the drawings.

[0052] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a deburring and leveling device for a heat exchanger flange plate after laser cutting processing includes an equipment body 1 and a conveyor belt 2. There is a processing area inside the equipment body 1. The conveyor belt 2 extends through the processing area to both ends of the equipment body 1. When processing parts 4, place the parts 4 at one end of the conveyor belt 2, and then convey the parts 4 into the processing area through the conveyor belt 2, and let the grinding mechanism in the processing area grind the parts 4. Among them, the grinding area of the grinding mechanism for the parts 4 includes the outer wall of the parts 4, the mounting holes on the parts 4, and the corners thereof. When the parts 4 are ground, place the parts 4 on the conveyor belt 2 and convey them to the other end of the equipment body 1. The loading robot 3 at the other end of the equipment body 1 adsorbs the parts 4 to the palletizing area. The model of the loading robot 3 is Epson LS6 robot. An electric suction cup is installed at the picking end of the loading robot 3, and the processed parts 4 are adsorbed through the electric suction cup, thus completing palletizing.

[0053] As Figure 5 , Figure 6As shown in the figure, the grinding mechanism includes a fixed disk 5 installed at the top inside the processing area. An annular groove is provided at the bottom end or around the fixed disk 5. A toothed ring 6 is rotatably installed in the annular groove. One side of the toothed ring 6 is provided with a first motor 7. The first motor 7 is fixed to the inner wall of the processing area. The output end of the first motor 7 is installed with a first gear 8. The first gear 8 meshes with the toothed ring 6. When the first motor 7 is started, the toothed ring 6 can be driven to rotate through the first gear 8. The bottom end of the toothed ring 6 is connected with a first two-axis moving member, and the first two-axis moving member can drive the first grinding member 13 to achieve planar movement effects in two directions, vertical and horizontal.

[0054] As Figure 6 shown in the figure, the first two-axis moving member includes a vertical shaft 9 fixed to the bottom end of the toothed ring 6. A slider 10 is slidably installed on the vertical shaft 9. A first telescopic rod 11 is connected between the top end of the slider 10 and the bottom end of the toothed ring 6. The side of the slider 10 is connected with a second telescopic rod 12. The end of the second telescopic rod 12 is connected with a first grinding member 13.

[0055] As Figure 7 shown in the figure, a clamping column 14 is connected to the bottom of the fixed disk 5. A visual sensor 50 is provided at the bottom of the clamping column 14. The visual sensor 50 can locate the position of the part 4 and cooperate with the industrial control computer for control. When the part 4 is conveyed by the conveyor belt 2 to directly below the clamping column 14, the conveyor belt 2 stops running. There are at least two pressing members 15 around the clamping column 14. A plurality of pressing members 15 are arranged centrosymmetrically around the clamping column 14. During use, the clamping column 14 is extended into the central opening of the fixed disk 5, and then a plurality of pressing members 15 are expanded outward, so as to support the part 4 and keep the part 4 in a relatively static state with the clamping column 14.

[0056] As Figure 8 shown in the figure, the specific operation mode of the pressing member 15 is that a cavity is provided in the middle of the clamping column 14. An active column 16 is arranged inside the cavity. The active column 16 can be slidably connected up and down inside the cavity. The top of the active column 16 is connected with a third telescopic rod 17. The third telescopic rod 17 is used to drive the active column 16 to move up and down. The bottom of the active column 16 is provided with a conical surface 18. One side of the pressing member 15 close to the conical surface 18 is provided with an inclined surface 19. The conical surface 18 contacts the inclined surface 19. When the active column 16 moves downward, it can interact with the inclined surface 19 to simultaneously expand a plurality of pressing members 15 outward, so that the end of the pressing member 15 abuts against the inner wall of the circular opening in the middle of the part 4. Limit blocks 20 are also provided at the upper and lower ends of the pressing member 15. Limit grooves matching the limit blocks 20 are provided on the side wall of the clamping column 14. The limit blocks 20 are slidably connected with the limit grooves, and a first spring 21 is also connected between the end of the limit block 20 and the inner wall of the limit groove.

[0057] As Figure 9 、 Figure 10As shown in the figure, a slide rail 22 is provided below the fixed disk 5. A sliding member 23 is slidably mounted on the slide rail 22. The cross-section of the sliding member 23 is rectangular. The front and rear surfaces of the sliding member 23 can be attached to the inner wall of the slide rail 22, so that the sliding member 23 can slide stably on the slide rail 22. A protective cover 25 is provided on the top of the sliding member 23. A second motor 24 is provided inside the protective cover 25. The output shaft of the second motor 24 passes through the middle of the sliding member 23 to the lower part of the sliding member 23 and is fixedly connected to the top of the clamping column 14, so as to drive the clamping column 14 to rotate. A third motor 26 is also provided inside the protective cover 25. The bottom output shaft of the third motor 26 passes through one side of the sliding member 23 to the lower part of the sliding member 23 and is fixedly connected to a second gear 27. The second gear 27 is located on one side of the slide rail 22. A rack 28 is connected to one side of the slide rail 22 close to the second gear 27. The rack 28 meshes with the second gear 27;

[0058] Through the above scheme, when the third motor 26 drives the second gear 27 to rotate, the second gear 27 rolls along the rack 28, so as to realize the synchronous sliding of the third motor 26 and the sliding member 23, and thus adjust the position of the clamping column 14.

[0059] As Figure 11 、 Figure 12 As shown in the figure, clamping rods 29 are provided on both sides of the clamping column 14. Hinged ears 30 are connected to the outer wall of the clamping column 14. One end of the clamping rod 29 close to the hinged ear 30 is connected with a third gear 31. Both ends of the third gear 31 are hinged to the hinged ear 30. A second rack 32 is provided on one side of the third gear 31. The second rack 32 meshes with the third gear 31. The top end of the second rack 32 is fixedly connected with a fourth telescopic rod 33. The fourth telescopic rod 33 is fixedly installed at both ends of the top of the clamping column 14. When the fourth telescopic rod 33 drives the second rack 32 to move up and down, under the meshing action of the second rack 32 and the third gear 31, the third gear 31 can also rotate, so as to adjust the angle of the clamping rod 29;

[0060] A fifth telescopic rod 34 is connected to the bottom of the end of the clamping rod 29 away from the clamping column 14. A moving frame 35 is connected to the bottom of the fifth telescopic rod 34. One end of the moving frame 35 is connected to a fourth motor 36. The output end of the fourth motor 36 is connected to a fourth gear 37. A fifth gear 38 is arranged below the fourth gear 37. The fifth gear 38 meshes with the fourth gear 37. A rotating shaft 39 is fixedly connected through the middle of the fifth gear 38. When the fourth gear 37 rotates, it can drive the fifth gear 38 and the rotating shaft 39 to rotate. The rotating shaft 39 is slidably connected to the bottom of the moving frame 35. One end of the moving frame 35 is fixedly connected to a sixth telescopic rod 40. The telescopic end of the sixth telescopic rod 40 is rotatably connected to one end of the rotating shaft 39. A second spring 41 and a rotating ring 49 are arranged between the fifth gear 38 and the moving frame 35. The rotating ring 49 is rotatably connected to the outer wall of the rotating shaft 39. The rotating ring 49 is connected to the moving frame 35 through the second spring 41. When the sixth telescopic rod 40 drives the rotating shaft 39 to move towards the part 4, due to its longer teeth, the fifth gear 38 can always mesh with the fourth gear 37. When the sixth telescopic rod 40 contracts, under the action of the second spring 41, the fifth gear 38 and the rotating shaft 39 synchronously return to the default position.

[0061] As Figure 13 、 Figure 14 、 Figure 15 shown, a rotating seat 42 is arranged on the outer wall of the clamping column 14. The rotating seat 42 is of an annular structure, and the annular rotating seat 42 is concentric with the mounting hole of the part 4. The rotating seat 42 is connected to the outer wall of the clamping column 14 through a connecting arm 48. A rotating block 43 is rotatably installed in the middle of the rotating seat 42. A second two-axis moving member is arranged at the bottom of the rotating block 43. The second two-axis moving member includes a seventh telescopic rod 44. The side of the bottom telescopic end of the seventh telescopic rod 44 is connected to an eighth telescopic rod 45. The end of the eighth telescopic rod 45 is connected to a second grinding member 46. The grinding area of the second grinding member 46 abuts against the inner wall corner of the mounting hole of the part 4. A fifth motor 47 is fixedly installed at the top of the rotating seat 42. The bottom output shaft of the fifth motor 47 is connected to the top of the rotating block 43, so that the fifth motor 47 can drive the rotating block 43 together with the second grinding member 46 to rotate along the central axis of the mounting hole of the part 4, so as to grind the inner wall of the mounting hole of the part 4;

[0062] It should be noted that the second grinding member 46 and the first grinding member 13 are respectively arranged at the upper and lower ends of the part 4. The first grinding member 13 and the second grinding member 46 can be made of materials such as silicon carbide, ceramic grinding stones, hard metals (such as stainless steel, titanium alloy).

[0063] Through the above content, at least the following preferred embodiments can be obtained:

[0064] Embodiment 1: The specific solution of this embodiment is as follows: The clamping column 14 is driven to rotate by the second motor 24. Since at least two pressing members 15 are supported against the inner wall of the central through hole of the part 4, the part 4 can be fixed on the clamping column 14. Therefore, the part 4 can rotate synchronously with the rotation of the clamping column 14. The first grinding member 13 moves in two axes on the P1 plane, where the P1 plane is a vertical plane passing through the central axis of the clamping column 14. Driven by the first telescopic rod 11 and the second telescopic rod 12 and controlled by the industrial control computer for the first telescopic rod 11 and the second telescopic rod 12, the first grinding member 13 moves on the P1 plane, so that the first grinding member 13 can move along the stepped shape on the outside of the part 4, thus perfectly adapting to the shape of the part 4. Compared with the two grinding rollers in the prior art for grinding the part 4, the effect is better, and the burrs at the fillet positions of the part 4 can be removed, improving the quality of the product. And in this embodiment, the clamping column 14 can slide on the slide rail 22 along with the sliding member 23, while the first grinding member 13 is always on the P1 plane. Therefore, when the sliding member 23 slides to one side on the slide rail 22, it can present Figure 16 the state shown in: The first grinding member 13 gradually deviates from the part 4, and one end of the first grinding member 13 away from the deviation direction can become a pushing surface 13a. This process generates: The pushing surface 13a pushes the burr waste on the part 4, so that the burr waste can be pushed to one side of the part 4. And in this process, the rotation direction of the part 4 and the clamping column 14 also needs to be configured so that the burrs of the part 4 can face the pushing surface 13a.

[0065] Embodiment 2: The specific solution of this embodiment is as follows: Only at least two pressing members 15 are supported against the inner wall of the central through hole of the part 4, while the clamping column 14 is in a fixed state. The first motor 7 drives the first gear 8 to rotate, and then the first gear 8 drives the toothed ring 6 to rotate, so that the toothed ring 6 drives the first two-axis moving member to rotate around the central axis of the part 4. At this time, the first grinding member 13 is moved to the grinding area at the center of the part 4 by the first telescopic rod 11 and the second telescopic rod 12, and then the first telescopic rod 11 and the second telescopic rod 12 are gradually expanded outward by the industrial control computer until the grinding area of one end face of the part 4 is ground.

[0066] Embodiment 3: The technical solution of this embodiment is different from that of Embodiment 1 or Embodiment 2 in that: A second grinding member 46 is further provided. The second grinding member 46 is installed on the part 4 through a rotating seat 42. During the grinding process, the rotating seat 42 and the part 4 are relatively fixed, and then the second grinding member 46 is driven by a fifth motor 47 to rotate around the central axis of the mounting hole of the part 4. Moreover, a second two-axis moving member and a rotating block 43 are connected between the part 4 and the fifth motor 47. In this embodiment, the second grinding member 46 together with its attached parts (including but not limited to the rotating seat 42, the fifth motor 47, the second two-axis moving member, and the rotating block 43) is adaptively changed according to the number of mounting holes on the parts 4 of different batches, and the rotating seat 42 is connected to the clamping column 14 by means of bolts or other connection methods.

[0067] Embodiment 4: The technical solution of this embodiment is different from that of Embodiment 3 in that: Since the second grinding member 46 and the first grinding member 13 can only grind one end of the part 4 at a time, in order to enable both sides of the part 4 to be ground by the first grinding member 13 and the second grinding member 46 respectively, so as to complete the overall grinding of the entire part 4, clamping rods 29 are provided on both sides of the clamping column 14. One end of the clamping rod 29 drives the rotating shaft 39 to move towards the part 4 through a sixth telescopic rod 40. Thus, the part 4 can be clamped by at least two groups of clamping rods 29, and then the fourth motor 36 drives the rotating shaft 39 to rotate, so that the rotating shaft 39 drives the part 4 to rotate, and the part 4 rotates 180 degrees. At this time, the first grinding member 13 and the second grinding member 46 can grind the other side of the part 4, and thus the grinding process of the entire part 4 is completed.

[0068] It should be noted that since the rotating shaft 39 will have movement interference with the clamping rod 29 when driving the part 4 to rotate, the position of the rotating shaft 39 can be adjusted by setting a fifth telescopic rod 34, so as to form enough space for the part 4 to rotate. At the same time, the fifth telescopic rod 34 and the clamping rod 29 also play the role of picking up the part 4. Through the cooperative clamping action of the fifth telescopic rod 34, the clamping rod 29, and the rotating shaft 39, the part 4 on the conveyor belt 2 is clamped to the outer wall of the clamping column 14, and then the part 4 is relatively fixed with it by the clamping column 14.

[0069] Example 5: The technical solution of this example is different from that of Example 4 in that: in this example, the second grinding member 46 together with its attached parts (including but not limited to the rotating seat 42, the fifth motor 47, the second two-axis moving member, and the rotating block 43) can be less than the number of mounting holes on the part 4. For example, there is only one set. When it is necessary to gradually process the mounting holes, through the cooperation of the clamping rod 29 and the clamping column 14, the part 4 is first rotated by a certain angle (this angle is the included angle between the two planes formed by the central axes of two adjacent mounting holes and the central axis of the part 4), then the part 4 is placed on the conveyor belt 2, and then the clamping rod 29 and the clamping column 14 are rotated back to the original angle. Then, the part 4 with the adjusted angle is clamped to the outer wall of the clamping column 14 through the cooperative clamping action of the fifth telescopic rod 34, the clamping rod 29, and the rotating shaft 39. Then, the part 4 is relatively fixed to it through the clamping column 14, so that the second grinding member 46 can grind the adjacent mounting hole that has been ground before.
