Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and more particularly to a processing device for the inner panel of an automobile side panel. Background Art

[0002] In the field of automobile manufacturing, as a key structural component of the vehicle body, the processing quality and efficiency of the inner panel of an automobile side panel directly affect the safety, comfort and production cycle of the whole vehicle. At present, the processing of the inner panel of an automobile side panel usually involves multiple processes such as stamping, welding, and forming. The processing devices used in each process are crucial for the production of the inner panel of the side panel.

[0003] The existing Chinese patent with the publication number CN111195933B discloses a cutting device for processing automobile side panels. However, the above patent and the existing technologies still have the following defects: First, the above patent uses a pressing mechanism to fix the inner panel of the side panel to be processed. Since the inner panel of the side panel is irregular in shape and its surface is uneven, when the pressing mechanism presses down, it may sink the protruding part of the inner panel of the side panel, resulting in deformation of the inner panel of the side panel, and further causing waste of raw materials and cost losses. Second, traditional technologies usually use special fixtures for plates to fix the inner panel of the side panel to be processed. However, traditional fixtures are fixedly arranged, that is, the position of the fixture is determined before the inner panel of the side panel is fixed. Then, when the size and shape of the inner panel of the side panel to be processed change, the fixture needs to be disassembled and assembled. Most fixtures are usually fixed with bolts, so a certain amount of time will be wasted during the disassembly and assembly process, which will ultimately affect the normal processing efficiency of the inner panel of the side panel.

[0004] Therefore, it is necessary to provide a processing device for the inner panel of an automobile side panel to solve the above problems. Summary of the Invention

[0005] Based on this, it is necessary to provide a processing device for the inner panel of an automobile side panel to address the problems in the prior art.

The number of inserting strips on each shifting sleeve is two, and the two inserting strips correspond to the two racks respectively.

[0010] Further, a convex ring is coaxially formed on the inner wall of each shifting sleeve. The inner ring of the convex ring fits with the outer wall of the column. A second spring is sleeved on the column. The two ends of the second spring abut against the convex ring and the slider respectively. Each receiving seat includes a first cylindrical shell and a second cylindrical shell. The first cylindrical shell is coaxially fixed at the top of the column. The second cylindrical shell is coaxially formed at the top of the first cylindrical shell. The outer diameter of the first cylindrical shell is larger than the outer diameter of the column.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, a fixture for fixing the side panel inner plate is installed on the fixture mounting seat of the device. In actual operation, the operator can position the fixture through the rotating mechanism, the translation mechanism and the lifting mechanism according to the size and shape of the current side panel inner plate. The rotating mechanism and the translation mechanism are used to make the fixture close to the outer edge of the side panel inner plate, and the lifting mechanism is used to make the fixture correspond to the outer edge of the side panel inner plate. The rotating mechanism, the translation mechanism and the lifting mechanism are easy to operate, so that the positioning of the fixture can be completed in a short time, and finally the processing efficiency of the side panel inner plate is improved; Secondly, the rotation mechanism and translation mechanism of the device are limited by the rotation locking member and the translation locking member respectively, that is, after the fixture is positioned, it can immediately lock its own position by the rotation locking member and the translation locking member, so as to ensure that during the processing of the side inner panel, the fixture can be stable at the current position and will not change; Thirdly, the pull sleeve that plays a locking control role in the translation locking member and the No. 2 toothed disk that plays a locking control role in the rotation locking member are connected through a connecting piece. Therefore, in actual operation, the operator only needs to press the pull sleeve to unlock the locked clamp, which facilitates the subsequent movement of the clamp and further improves the portability of the clamp positioning operation.

Specific embodiments

[0018] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 17An inner panel processing device for an automobile side panel shown in the figure includes a center rest 1 and four brackets 2 distributed in a matrix around the center rest 1. A circular block 3 close to the center rest 1 is formed on each bracket 2. A fixture moving component 4 is provided on each bracket 2. Each group of fixture moving components 4 includes a rotating mechanism, a translation mechanism, a lifting mechanism and a fixture mounting seat 5. The rotating mechanism includes a rotating arm 6 and a rotation locking member. The rotating arm 6 is horizontal. One end of the rotating arm 6 is a hinged end rotatably connected to the circular block 3, and the other end of the rotating arm 6 is a free end. The rotation locking member includes a first jaw clutch disc 7 and a second jaw clutch disc 8 distributed vertically. The first jaw clutch disc 7 is fixedly connected to the circular block 3, and the second jaw clutch disc 8 is elastically connected to the hinged end of the rotating arm 6. The translation mechanism includes a slider 9 and a translation locking member. The slider 9 is slidably connected to the rotating arm 6 along the length direction of the rotating arm 6. A column 10 is fixedly provided on the slider 9. The translation locking member includes a rack 11 and a shifting sleeve 12. The rack 11 is horizontal and fixedly connected to the rotating arm 6. The shifting sleeve 12 is sleeved on the column 10, and the shifting sleeve 12 is elastically connected to the slider 9. An inserting bar 13 for inter-tooth positioning cooperation with the rack 11 is formed on the shifting sleeve 12. A connecting member connecting the two is provided between the shifting sleeve 12 and the second jaw clutch disc 8. The lifting mechanism includes a receiving seat 14 and a lifting screw 15. The receiving seat 14 is connected to the column 10. The lifting screw 15 is vertically arranged in the receiving seat 14. The fixture mounting seat 5 is connected to the top of the lifting screw 15.

[0020] During actual use, a fixture (not shown in the figure) is fixedly provided on each fixture mounting seat 5. When processing the inner panel of the side wall, the inner panel of the side wall is fixed by four fixtures. This device is used to quickly adjust the position of the fixtures according to the size and shape of the current inner panel of the side wall. In the initial state, both the shifting sleeve 12 and the second split hub 8 are in the raised state. At this time, the insertion bar 13 on the shifting sleeve 12 will insert into the tooth groove on the rack 11, and the second split hub 8 will move upward to engage with the first split hub 7. Then, the translation of the slider 9 will be restricted by the cooperation between the insertion bar 13 and the rack 11, and the rotation of the swing arm 6 will be restricted by the cooperation between the first split hub 7 and the second split hub 8. Finally, the fixture mounting seat 5 will be fixed at the current position. When it is necessary to quickly adjust the fixture, press down the shifting sleeve 12. The shifting sleeve 12 will drive the insertion bar 13 to separate from the tooth groove on the rack 11 downward. At the same time, through the action of the connecting piece, the second split hub 8 will be driven to descend together with the shifting sleeve 12. In this way, the second split hub 8 will separate from the first split hub 7. Finally, both the slider 9 and the swing arm 6 are in a free state. At this time, the swing arm 6 is used to drive the fixture mounting seat 5 to approach the inner panel of the side wall, and at the same time, according to the size of the current inner panel of the side wall, the slider 9 is used to drive the fixture mounting seat 5 to move to the edge of the inner panel of the side wall. Since the inner panel of the side wall is irregular, the edge of the inner panel of the side wall is uneven. Then, at this time, the lifting screw rod 15 arranged in the receiving seat 14 is used to drive the fixture mounting seat 5 to rise and fall, and finally the fixture on the fixture mounting seat 5 corresponds to the edge of the inner panel of the side wall. When the position of the fixture is determined, release the shifting sleeve 12. The shifting sleeve 12 and the second split hub 8 will rise synchronously. At this time, the translation of the slider 9 will be restricted again by the cooperation between the insertion bar 13 and the rack 11, and the rotation of the swing arm 6 will be restricted again by the cooperation between the first split hub 7 and the second split hub 8. In this way, the fixture mounting seat 5 will be fixed at the current position. Finally, the inner panel of the side wall is clamped and fixed by the fixtures on the four fixture mounting seats 5.

[0021] In order to show how one end of the swing arm 6 is rotatably connected to the circular block 3, the following features are provided: One end of each swing arm 6 is fixedly connected with an end plate 16 that is horizontal and located below the corresponding circular block 3. A vertical rotating shaft 17 is fixedly provided on the end plate 16. A columnar through groove 18 is opened at the center of each circular block 3. A fixed sleeve 19 is coaxially arranged in the columnar through groove 18. A first bearing 20 is embedded in the fixed sleeve 19. The upper end of the rotating shaft 17 is vertically and upwardly connected to the first bearing 20. The first split hub 7 is sleeved outside the fixed sleeve 19 in a ring shape.

[0022] The first jaw clutch disc 7 is fixedly connected to the corresponding circular block 3 through the fixing sleeve 19. Each swing arm 6 is rotatable through the rotating shaft 17 connected to the first bearing 20. The end of the swing arm 6 where the rotating shaft 17 is provided is the hinged end where the swing arm 6 is rotatably connected to the circular block 3. During actual installation, the rotating shaft 17 is inserted into the first bearing 20 by interference fit, and after the rotating shaft 17 is inserted into the first bearing 20, a snap ring (not shown in the figure) is installed on the rotating shaft 17 to prevent the axial displacement of the rotating shaft 17, thereby ensuring that the hinged end of the swing arm 6 will not separate from the circular block 3.

[0023] In order to show the specific installation method of the second jaw clutch disc 8, the following features are set: On the outer wall of the lower end of each rotating shaft 17, a number of limiting strips 21 evenly distributed along the circumferential direction of the rotating shaft 17 are formed. Each limiting strip 21 is vertical. A sliding sleeve 22 is sleeved on the lower end of each rotating shaft 17. A number of limiting grooves 23 matching with the limiting strips 21 are formed on the inner wall of the sliding sleeve 22. A coaxial annular seat 24 is formed on the top of the sliding sleeve 22. The second jaw clutch disc 8 is coaxially and fixedly arranged on the top of the annular seat 24. A vertical first spring 25 is sleeved on each sliding sleeve 22. The two ends of the first spring 25 are respectively in contact with the annular seat 24 and the end plate 16.

[0024] During actual processing, a number of first teeth 55 evenly distributed along the circumferential direction of the bottom surface of the first jaw clutch disc 7 are formed, and a number of second teeth 56 evenly distributed along the circumferential direction of the top surface of the second jaw clutch disc 8 are formed. In the initial state, the first spring 25 releases elastic force to drive the annular seat 24 to be in the rising state. At this time, the second jaw clutch disc 8 will move upward to fit with the first jaw clutch disc 7. Each first tooth 55 will upwardly embed into the tooth groove between adjacent second teeth 56. Since the first jaw clutch disc 7 is in a fixed state, the second jaw clutch disc 8 will not rotate at this time. The second jaw clutch disc 8 is connected to the sliding sleeve 22 through the annular seat 24. The sliding sleeve 22 can control the rotation of the rotating shaft 17 through the cooperation of the limiting strip 21 and the limiting groove 23. Then when the second jaw clutch disc 8 cannot rotate, the rotating shaft 17 is restricted from rotating. When the shifting sleeve 12 is pressed downward, the shifting sleeve 12 drives the second jaw clutch disc 8 to descend together through the connecting piece. During this process, the second jaw clutch disc 8 separates from the first jaw clutch disc 7. Each limiting strip 21 slides in the corresponding limiting groove 23, and the annular seat 24 compresses the first spring 25 downward. When the second jaw clutch disc 8 separates from the first jaw clutch disc 7, the rotating shaft 17 is in a free state. Then at this time, the rotation of the swing arm 6 can be controlled. When the swing arm 6 rotates through the rotating shaft 17, the sliding sleeve 22 and the second jaw clutch disc 8 will rotate together with the rotating shaft 17. When the position of the fixture is determined, the shifting sleeve 12 is released. At this time, the first spring 25 will release elastic force again to drive the annular seat 24 to rise, and the second jaw clutch disc 8 will move upward to fit with the first jaw clutch disc 7 again. Finally, the rotating shaft 17 will be restricted from rotating again.

[0025] In order to show how the slider 9 is slidably connected to the swing arm 6, the following features are provided: In each swing arm 6, a strip-shaped accommodation groove 26 is formed along its length direction. Two symmetrically arranged strip-shaped vertical plates 27 are fixedly provided in the strip-shaped accommodation groove 26. The length direction of each strip-shaped vertical plate 27 is parallel to the length direction of the strip-shaped accommodation groove 26. A strip-shaped sliding groove 28 is formed along the length direction of each strip-shaped vertical plate 27. Each slider 9 is arranged between the corresponding two strip-shaped vertical plates 27. Guide sliding strips 29 are formed at both ends of each slider 9. Each guide sliding strip 29 slides in the corresponding strip-shaped sliding groove 28. The number of racks 11 in each translation locking member is two. Each rack 11 is fixed in the strip-shaped accommodation groove 26, and each rack 11 is located above the corresponding strip-shaped vertical plate 27. The number of inserting strips 13 on each shifting sleeve 12 is two, and the two inserting strips 13 correspond to the two racks 11 respectively.

[0026] Each slider 9 slides in the corresponding strip-shaped accommodation groove 26, and the sliding direction of the slider 9 is restricted by the cooperation between the guide sliding strip 29 and the strip-shaped sliding groove 28, ensuring that the slider 9 can only slide along the length direction of the swing arm 6. Finally, the displacement of the fixture mounting base 5 is controlled by the sliding of the slider 9.

[0027] In order to show the specific installation method of the shifting sleeve 12, the following features are provided: A convex ring 30 is coaxially formed on the inner wall of each shifting sleeve 12. The inner ring of the convex ring 30 is in contact with the outer wall of the column 10. A second spring 31 is sleeved on the column 10. The two ends of the second spring 31 are respectively in contact with the convex ring 30 and the slider 9. Each receiving seat 14 includes a first columnar shell 32 and a second columnar shell 33. The first columnar shell 32 is coaxially fixed to the top of the column 10. The second columnar shell 33 is coaxially formed on the top of the first columnar shell 32. The outer diameter of the first columnar shell 32 is larger than the outer diameter of the column 10. Each convex ring 30 abuts against the bottom of the corresponding first columnar shell 32 upwards.

[0028] In the initial state, the second spring 31 releases elastic force to drive the sleeve 12 to rise. At this time, the convex ring 30 provided on the inner wall of the sleeve 12 will move upward to contact the bottom of the first columnar shell 32, so as to limit the upward travel of the sleeve 12 through the first columnar shell 32. When the sleeve 12 rises to a stop, each insert 13 provided on the sleeve 12 will be inserted into the tooth groove on the corresponding rack 11. Then, the slider 9 is restricted from sliding and cannot be displaced. When it is necessary to change the position of the fixture mounting seat 5, press down the sleeve 12. The sleeve 12 will compress the second spring 31, causing the second spring 31 to generate elastic force. At the same time, the insert 13 on the sleeve 12 will separate from the rack 11 downward, and the slider 9 will become free. Finally, the fixture mounting seat 5 can be controlled to displace by sliding the slider 9. When the position of the fixture mounting seat 5 is determined, release the sleeve 12. At this time, the second spring 31 will release elastic force again to drive the sleeve 12 to rise, and the insert 13 on the sleeve 12 will be inserted into the tooth groove on the rack 11 upward again. Finally, the slider 9 will be restricted from sliding again.

[0029] In order to show how the lifting screw 15 realizes lifting, the following features are set: The upper end of the second columnar shell 33 is coaxially embedded with a second bearing 34. An internal thread sleeve 35 is provided in the second columnar shell 33 and is connected to the second bearing 34. An annular rotating cap 36 is coaxially formed on the outer wall of the upper end of the internal thread sleeve 35. The lower end of the lifting screw 15 passes through the internal thread sleeve 35 and then penetrates into the second columnar shell 33, and the lifting screw 15 is in threaded cooperation with the internal thread sleeve 35. The fixture mounting seat 5 is circular, and a fixing ring 37 is coaxially fixed on the outer wall of the fixture mounting seat 5. Two symmetrically arranged limiting rods 38 are fixedly provided on the fixing ring 37. Two symmetrically arranged limiting sleeves 39 are formed on the outer wall of the second columnar shell 33. Each limiting rod 38 vertically penetrates through the corresponding limiting sleeve 39 downward.

[0030] When it is necessary to control the lifting of the fixture mounting seat 5, rotate the annular rotating cap 36. When the annular rotating cap 36 rotates, the annular rotating cap 36 will drive the internal thread sleeve 35 to rotate. Since the lifting screw rod is restricted from rotating through the cooperation of the limiting rod 38 and the limiting rod 38, when the internal thread sleeve 35 rotates, the lifting screw 15 in threaded cooperation with the internal thread sleeve 35 will be driven to lift. Finally, the fixture provided on the fixture mounting seat 5 will be driven to lift, so that the fixture corresponds to the uneven edge part of the inner panel of the side wall.

[0031] In order to show the rotation of the stable rotating arm 6, the following features are set: A sector-shaped frame 40 is formed on each bracket 2. A tail frame 41 is fixedly provided at the free end of each rotating arm 6. A vertically downward support column 42 is fixedly provided on the tail frame 41. A ball 43 is embedded at the bottom of the support column 42, and the ball 43 travels on the arc-shaped outer edge of the corresponding sector-shaped frame 40.

[0032] Each sector frame 40 is concentric with the corresponding circular block 3. When the swing arm 6 rotates, the hinged end of the swing arm 6 provides a degree of rotational freedom, and the free end of the swing arm 6 will rotate. During this process, the ball 43 provided on the support column 42 will roll on the arc-shaped outer edge of the sector frame 40, so as to stabilize the rotation of the swing arm 6 through the supporting action of the support column 42 and prevent the swing arm 6 from being in a suspended state.

[0033] In order to show the specific structure of the connecting piece, the following features are provided: Each connecting piece includes a connecting ring 44, a flat rod 45 and a transmission rod 46. The connecting ring 44 is coaxially sleeved outside the corresponding sliding sleeve 22, and the connecting ring 44 is fixed to the bottom of the annular seat 24. A horizontal connecting plate 47 is provided below each end plate 16. A plurality of vertical connecting rods 48 are formed on the connecting ring 44 and are fixedly connected to the connecting plate 47. The flat rod 45 is arranged below the corresponding swing arm 6. The axial direction of the flat rod 45 is parallel to the length direction of the swing arm 6, and one end of the flat rod 45 is fixedly connected to the connecting plate 47. A strip-shaped avoidance groove 49 is formed along the length direction at the bottom of each swing arm 6. The transmission rod 46 is vertical. The upper end of the transmission rod 46 is fixedly connected to the corresponding shifting sleeve 12. The lower end of the transmission rod 46 sequentially passes through the slider 9 and the strip-shaped avoidance groove 49 and extends towards the flat rod 45, and a connecting sleeve 50 sleeved on the flat rod 45 is formed at the lower end of the transmission rod 46.

[0034] When the shifting sleeve 12 is pressed downwards, the shifting sleeve 12 will drive the flat rod 45 to descend through the transmission rod 46 and the connecting sleeve 50. At this time, the flat rod 45 will drive the connecting ring 44 to descend through the connecting plate 47 and the connecting rod 48. Since the connecting ring 44 is fixedly connected to the annular seat 24, the second jaw clutch disc 8 provided on the annular seat 24 will descend synchronously with the shifting sleeve 12. Finally, the slider 9 and the rotating shaft 17 will simultaneously become free states. When the shifting sleeve 12 is released, the shifting sleeve 12 rises and resets elastically through the second spring 31, and the second jaw clutch disc 8 rises and resets elastically through the first spring 25. When the slider 9 slides, the transmission rod 46 fixedly connected to the shifting sleeve 12 will slide in the strip-shaped avoidance groove 49. At the same time, the connecting sleeve 50 will slide on the transmission rod 46, avoiding the transmission rod 46 through the strip-shaped avoidance groove 49, and ensuring that no matter how the slider 9 slides, when the shifting sleeve 12 is pressed downwards, the shifting sleeve 12 can drive the flat rod 45 to descend through the connecting sleeve 50. Since the transmission rod 46 passes through the slider 9 downwards, the shifting sleeve 12 will be limited by the transmission rod 46 and cannot rotate, finally ensuring that the shifting sleeve 12 can only move up and down.

[0035] In order to improve the stability of the flat rod 45 when the shifting sleeve 12 drives the flat rod 45 to descend, the following features are provided: A horizontal support plate 51 is fixedly provided on the outer wall of each support column 42. A vertical rod 52 that passes vertically upward through the support plate 51 is formed at one end of each flat rod 45 facing the support column 42. A circular limit block 53 is coaxially and fixedly provided at the top of the vertical rod 52. A third spring 54 is sleeved on the vertical rod 52, and the two ends of the third spring 54 are respectively in contact with the limit block 53 and the support plate 51.

[0036] When the shifting sleeve 12 is pressed downward, the shifting sleeve 12 will drive the flat rod 45 to descend through the transmission rod 46. At this time, the vertical rod 52 connected to the flat rod 45 will compress the third spring 54 through the limit block 53. Then when the flat rod 45 descends, its two ends will be respectively supported by the first spring 25 and the third spring 54, so as to improve the stability of the flat rod 45 and prevent the connection between the flat rod 45 and the connecting plate 47 from breaking due to single-point support.

[0037] Working principle: During the actual use process, a fixture (not shown in the figure) is fixedly provided on each fixture mounting seat 5. When processing the inner panel of the side wall, the inner panel of the side wall is fixed by four fixtures. This device is used to quickly adjust the position of the fixtures according to the size and shape of the current inner panel of the side wall. In the initial state, both the shifting sleeve 12 and the second jaw clutch 8 are in the rising state. At this time, the insertion bar 13 on the shifting sleeve 12 will insert into the tooth slot on the rack 11, and the second jaw clutch 8 will upwardly engage with the first jaw clutch 7. Then the slider 9 will be restricted from translating due to the cooperation between the insertion bar 13 and the rack 11, and the rotating arm 6 will be restricted from rotating due to the cooperation between the first jaw clutch 7 and the second jaw clutch 8. Finally, the fixture mounting seat 5 will be fixed at the current position. When the fixture needs to be quickly adjusted, press the shifting sleeve 12 downward. The shifting sleeve 12 will drive the insertion bar 13 to separate from the tooth slot on the rack 11 downward. At the same time, through the action of the connecting piece, the second jaw clutch 8 will be driven to descend together with the shifting sleeve 12. In this way, the second jaw clutch 8 will separate from the first jaw clutch 7. Finally, both the slider 9 and the rotating arm 6 are in a free state. At this time, the rotating arm 6 is used to drive the fixture mounting seat 5 to approach the inner panel of the side wall, and at the same time, according to the size of the current inner panel of the side wall, the slider 9 is used to drive the fixture mounting seat 5 to move to the edge part of the inner panel of the side wall. Since the inner panel of the side wall is irregular, the edge part of the inner panel of the side wall is uneven. Then at this time, the lifting screw rod 15 arranged in the receiving seat 14 is used to drive the fixture mounting seat 5 to rise and fall, and finally the fixture on the fixture mounting seat 5 corresponds to the edge part of the inner panel of the side wall. When the position of the fixture is determined, release the shifting sleeve 12. The shifting sleeve 12 and the second jaw clutch 8 will rise synchronously. At this time, the slider 9 will be restricted from translating again due to the cooperation between the insertion bar 13 and the rack 11, and the rotating arm 6 will be restricted from rotating again due to the cooperation between the first jaw clutch 7 and the second jaw clutch 8. In this way, the fixture mounting seat 5 will be fixed at the current position. Finally, the inner panel of the side wall is clamped and fixed by the fixtures on the four fixture mounting seats 5.
