Description

Technical Field

[0001] This application relates to the technical field of clamping welding, and particularly to an integrated device for automatic clamping and welding of automotive parts. Background Art

[0002] Automotive parts refer to components, devices, and tools used in automotive manufacturing, repair, and maintenance, which are the various units that make up an automobile and a kind of product serving the automobile. Automotive part welding refers to connecting different parts of automotive parts together through a welding process. This connection method can provide strong support and stability to ensure the structural firmness and reliability of automotive parts. In the processing and production of automotive parts, fixture tools are extremely frequently used. Fixture tools can be used to quickly fasten workpieces, making the welding and fixing between parts more convenient.

[0003] For example, in the existing Chinese patent with the publication number CN116423135B, it discloses a fixture tool for welding automotive parts, which includes a workbench. A mounting groove with a U-shaped cross-section is formed in the middle of the workbench. A support device for supporting automotive parts is slidably arranged in the mounting groove, and pressing devices for pressing the automotive parts are respectively arranged on both sides of the support device in the mounting groove. Through the above-mentioned prior art, the support device is used to support the automotive parts, and the upper side presses the automotive parts through the pressing device, thereby forming a fixation; on the support device, through the arranged lifting cylinder and the slidably arranged U-shaped frame, when supporting the parts, the support device can be moved, and at the same time, the height of the support platform can be adjusted. After adjusting the height, through the arranged precision support assembly, the support for parts with different shapes can be completed, that is, it is convenient for the pressing device to press and fix the parts, and at the same time, it is convenient to process and fix them.

[0004] However, the above-mentioned prior art has the following technical defects:

[0005] Through the above-mentioned prior art, when processing automotive parts, the support device is used to support the automotive parts, and the pressing device is used to press and fix the automotive parts; through the arrangement of two groups of support devices and pressing devices, multiple groups of parts can be clamped and fixed during processing, which is convenient for welding. However, due to the separate and independent adjustment of the two groups of support devices and pressing devices, after clamping and fixing two automotive parts, the welding points at the butt joints of the two automotive parts are prone to deviation, and the support device and the pressing device need to be adjusted repeatedly many times to align the welding joints between the two automotive parts, resulting in a long and cumbersome adjustment process.

[0006] Secondly, after the above device clamps and fixes two auto parts, it cannot be flipped and adjusted anymore, which is not convenient for adjusting the welded parts. It can only be applied to a single working condition environment, with poor flexibility in adjustment, and the space for effective welding operation is fixed.

[0007] Based on this, on the basis of an existing fixture for welding auto parts, in order to overcome the above technical defects, there is still room for improvement. Summary of the Invention

Detailed implementation mode

[0042] The following will Figures 1 - 14 further elaborate on this application in detail.

[0043] The embodiment of this application discloses an integrated device for automatic clamping and welding of automotive parts, which can quickly position and clamp two parts with different shapes, and after clamping and fixing, can be flexibly rotated and adjusted to facilitate full-round welding of the connection, ensuring the connection stability between the parts and meeting the requirements for various working conditions.

[0044] Embodiment 1:

[0045] Refer to Figure 1As shown in the figure, the present application provides an integrated device for automatic clamping and welding of automotive parts, including a base 1 and a control console 11 installed on the upper side of the base 1. A mounting seat 12 is rotatably provided on one side of the control console 11, and a welding device 13 is arranged in the mounting seat 12. A positioning and clamping device 2 is provided on the control console 11 for automatically positioning, clamping and fixing two parts with different shapes, so that the two parts can be quickly and accurately butted. Subsequently, the staff can rotate the mounting seat 12 towards the middle of the control console 11 and weld the two parts through the welding device 13. The welding device 13 in this embodiment is preferably composed of an electric welding machine, a welding clamp and a welding rod. Since this is a known prior art, no further elaboration will be made here.

[0046] Referring to Figure 2 and Figure 3 As shown in the figure, specifically, the positioning and clamping device 2 includes a circular base 21 penetrating and rotatably arranged in the middle of the control console 11. A middle hole slot 111 for the rotational installation of the circular base 21 is penetratingly opened on the control console 11. It should be noted that the bottom of the circular base 21 penetrates downward and extends out of the middle hole slot 111 to facilitate the staff to rotate the circular base 21 when needed. A bottom bracket 22 is installed in the middle on the upper side of the circular base 21. The bottom bracket 22 is fixedly connected to the circular base 21, and the center point of the circular base 21 and the center point of the bottom bracket 22 are on the same central axis; an upper disc 24 is rotatably arranged above the bottom bracket 22 on the control console 11 through the side position clamping plates 23. The upper disc 24 has a central axis through hole 241. A fixing mechanism 3 is provided on the bottom bracket 22 and the circular base 21, and a clamping unit 4 is provided on the lower side of the upper disc 24. Different-shaped parts can be positioned and clamped respectively through the fixing mechanism 3 and the clamping unit 4.

[0047] When in use, first place one of the parts in the fixing mechanism 3 of the bottom bracket 22, pass another columnar part through the central axis through hole 241 and place it in the clamping unit 4. Subsequently, under the operation of the fixing mechanism 3 and the clamping unit 4, the two parts can be quickly positioned and then clamped and limited to ensure that the two parts can be accurately butted. After the butting is completed, the staff can perform a full-range welding operation on the connection of the two parts through the welding device 13.

[0048] Referring to Figure 4The two cams 32 are fixed together by the two cams 33 and the two cams 33 are connected to each other by the two cams 33. When the two cams 33 are connected, the cams 33 are connected to the two cams 33.

[0049] A driving motor 34 connected to one end of the inner bidirectional screw 32 is provided on one side of the bottom bracket 22 through a motor support 33. The positioning assembly 5 is provided on the round base 21 on both sides of the bottom bracket 22, and is used to adjust the position angle of the accessories placed on the bottom bracket 22. Starting the driving motor 34 can drive the two T-shaped clamps 31 to slide synchronously toward the center of the bottom bracket 22, so as to achieve the effect of clamping and fixing the accessories on both sides. It should be noted that before the accessories are completely clamped and fixed, the position angle of the accessories will be adjusted first under the operation of the positioning assembly 5, and finally the two T-shaped clamps 31 will be used to clamp the two sides of the accessories, so as to finally achieve the effect of positioning, clamping and fixing the accessories.

[0050] Reference Figure 4 and Figure 5 As shown, in order to quickly position the accessories on the bottom bracket 22, the positioning assembly 5 includes a U-shaped shift rod 51 and a linkage 6; the U-shaped shift rod 51 is symmetrically limited and slidably arranged on the round base 21 through a dovetail block 52, and the round base 21 is symmetrically provided with a dovetail groove 211 for the dovetail block 52 to slide. The U-shaped shift rod 51 is limited and slidably provided with a positioning plate 54 at one end toward the bottom bracket 22 through two square connecting rods 53. It should be noted that the two square connecting rods 53 and the positioning plate 54 are fixedly connected; the U-shaped shift rod 51 is symmetrically provided with square holes 511 for the square connecting rod 53 to penetrate, and the square connecting rod 53 is sleeved with a side spring 55. Under the action of the side spring 55, the positioning plate 54 always conflicts with one end of the U-shaped shift rod 51.

[0051] Moreover, the force of the side spring 55 is relatively large. Although the positioning abutting plate 54 is slidably connected to the U-shaped moving rod 51 through two square connecting rods 53, due to the existence of the side spring 55, when the U-shaped moving rod 51 is driven to slide, it will synchronously drive the positioning abutting plate 54 to move until the positioning abutting plate 54 is restricted by resistance and cannot move further. At this time, the side spring 55 is compressed, and the U-shaped moving rod 51 can continue to be forced to slide. The linkage 6 is arranged in the middle of the circular base 21 and is used to control the synchronous sliding of the two U-shaped moving rods 51 under the sliding drive of the T-shaped clamping plate 31.

[0052] Referring Figure 6 and Figure 7 As shown, since it is necessary to drive the U-shaped moving rod 51 synchronously while the T-shaped clamping plate 31 moves, the linkage 6 includes an inner mounting seat 61 and an L-shaped rack 62; the inner mounting seat 61 is installed on the upper middle side of the circular base 21 and is located between the two U-shaped moving rods 51. A transmission screw rod 63 that penetrates through the two positioning abutting plates 54 and threadedly penetrates through the two U-shaped moving rods 51 is rotatably arranged on the inner mounting seat 61. A circular through hole 541 for the transmission screw rod 63 to penetrate is formed through the positioning abutting plate 54, and a threaded through hole 512 adapted to the transmission screw rod 63 is threadedly penetrated through the U-shaped moving rod 51; when the transmission screw rod 63 is forced to rotate, it can synchronously drive the two U-shaped moving rods 51 to slide in cooperation with the threaded through hole 512 opened on the U-shaped moving rod 51.

[0053] One end of the L-shaped rack 62 penetrates through the bottom bracket 22 and is installed on the lower side of the T-shaped clamping plate 31. A rectangular sliding opening 223 communicating with the T-shaped sliding groove 221 and for the L-shaped rack 62 to penetrate and install is formed on the bottom bracket 22. A driving gear 64 meshing with the L-shaped rack 62 is sleeved on the middle part of the transmission screw rod 63. When the T-shaped clamping plate 31 is driven by the driving motor 34 to slide towards the center of the bottom bracket 22, the driving gear 64 will be driven by the L-shaped rack 62 to drive the transmission screw rod 63 to rotate; the rotating transmission screw rod 63 can synchronously drive the two U-shaped moving rods 51 to slide away from the bottom bracket 22 and synchronously drive the positioning abutting plate 54 to move until the two positioning abutting plates 54 both abut against the inner side of the fitting on the bottom bracket 22. Due to the relatively large force of the side spring 55, when the positioning abutting plate 54 abuts against the inner side of the fitting, it will first adjust the position angle of the fitting, and under the synchronous abutting adjustment of the two positioning abutting plates 54, the center point of the fitting will be in the same plane as the center point of the bottom bracket 22.

[0054] At this time, the positioning plate 54 cannot move further due to the conflict with the accessory, while the U-shaped shift rod 51 can continue to slide and drive the side spring 55 to contract until the two T-shaped clamps 31 are in conflict and clamped on both sides of the accessory. The two T-shaped clamps 31 can slide synchronously toward the center of the bottom bracket 22 to adjust the position of the accessory again, so that the accessory is finally in the center of the bottom bracket 22. After the positioning plate 54 and the T-shaped clamp 31 adjust the position of the accessory twice, the center point of the accessory and the center point of the bottom bracket 22 are on the same central axis. In this way, the effect of quickly positioning, clamping and fixing the accessory placed on the bottom bracket 22 can be achieved by driving the drive motor 34.

[0055] Reference Figure 8 and Figure 9 As shown, in order to be able to clamp and position another accessory of a different shape so that it can be accurately docked with the accessory on the bottom bracket 22, the clamping unit 4 includes a supporting plate 41, a clamping rod 42 and a clamping assembly 7; the supporting plate 41 is slidably and laterally limited on the side wall of the control panel 11 between the bottom bracket 22 and the upper disc 24 through the bottom supporting rod 43, and a limiting hole 112 is opened through the control panel 11 for the sliding installation of the bottom supporting rod 43. In this embodiment, preferably, three clamping rods 42 are rotatably installed on the lower side of the upper disc 24 in a circular distribution and equidistantly through the bottom side seat 44, and the clamping assembly 7 is arranged on the clamping rod 42 and the lower side of the upper disc 24, and is used to drive the three clamping rods 42 to rotate to position and clamp another columnar accessory.

[0056] In the initial state, the supporting plate 41 is directly below the central axis through hole 241 of the upper disc 24. One end of another columnar accessory is passed through the central axis through hole 241 and placed on the supporting plate 41. Under the operation of the clamping assembly 7, the position of the columnar accessory can be adjusted and clamped so that the columnar accessory and the accessory on the bottom bracket 22 are on the same central axis to ensure that the two accessories can be accurately docked.

[0057] Continue to refer to Figure 9 As shown, since multiple clamping rods 42 need to be driven synchronously to achieve the positioning and clamping effect of the accessories, the clamping assembly 7 includes a driving cylinder 71 with the telescopic end facing downward and symmetrically installed on the lower side of the upper disk 24, and the telescopic ends of the two driving cylinders 71 are provided with control rings 72. The control ring 72 and the telescopic ends of the two driving cylinders 71 are fixedly connected. In the initial state, the two driving cylinders 71 are fully extended, the control ring 72 is at the lowest position, and the ends of the three clamping rods 42 away from the bottom side seat 44 are all in the control ring 72; the control ring 72 and the clamping rod 42 are provided with a resistance member 8 for synchronously resisting the clamping rod 42 and the columnar accessories.

[0058] Reference Figure 10As shown, it is a schematic diagram of the structure of the resisting member 8 in this embodiment. The resisting member 8 includes three resisting seats 81 which are equidistantly arranged on the upper side of the control ring 72 in an annular distribution, and the positions of the three resisting seats 81 correspond to the three clamping rods 42. The resisting seat 81 is rotatably mounted with a magnet wheel 82 at one end facing the clamping rod 42. The clamping rod 42 is provided with a rectangular groove 421 adapted to the magnet wheel 82 on one side facing the resisting seat 81. An embedded iron sheet 83 is provided in the rectangular groove 421 of the clamping rod 42. The embedded iron sheet 83 is fixedly installed in the rectangular groove 421. The magnet wheel 82 resists and is adsorbed on the embedded iron sheet 83 in the rectangular groove 421. Under the action of suction, the magnet wheel 82 is always in the rectangular groove 421. A follow-up clamp 84 is provided at one end of the clamping rod 42 away from the bottom seat 44, which is used to adjust the position of the columnar accessory and resist and clamp it.

[0059] Starting the two driving cylinders 71 to contract can drive the control ring 72 to move upward smoothly. Through the resistance of the magnet round wheel 82, the three clamping rods 42 can be synchronously driven to rotate toward the columnar accessory. In conjunction with the follow-up clamp 84, the columnar accessory can be positioned and clamped.

[0060] Reference Figure 10 and Figure 11 As shown, in order to cooperate with the rotating clamping rod 42 and smoothly clamp the accessories on the supporting plate 41, the follower clamp 84 includes an arc-shaped clamping plate 842 hingedly arranged at one end of the clamping rod 42 away from the bottom side seat 44 through an inner circular shaft 841, and a compound torsion spring 843 is sleeved on the inner circular shaft 841 for driving the arc-shaped clamping plate 842 to rotate, and a limiting stop block 844 is installed on the arc-shaped clamping plate 842 toward the side of the clamping rod 42. It should be noted that the compound torsion spring 843 always has the driving force to drive the arc-shaped clamping plate 842 to rotate upward. In conjunction with the limit stop block 844, it can be achieved that in the initial state, that is, when the two driving cylinders 71 are fully extended and the control ring 72 is at the lowest position, the arc-shaped clamping plate 842 is always in a vertical state to ensure that when the control ring 72 is driven upward by the driving cylinder 71 and drives the clamping rod 42 to rotate toward the columnar accessory, the bottom inner side of the arc-shaped clamping plate 842 will first contact the columnar accessory, and the arc-shaped clamping plate 842 will rotate under the resistance, to ensure that the inner arc surface of the arc-shaped clamping plate 842 will completely resist the columnar accessory.

[0061] When the position of the columnar accessory is offset, the arc-shaped clamping plate 842 on one side will first contact the columnar accessory to adjust and push the columnar accessory to the center of the three arc-shaped clamping plates 842. When the three arc-shaped clamping plates 842 are all clamped and contacted on the columnar accessory, the position adjustment of the columnar accessory is completed. At this time, the columnar accessory and the accessory on the bottom bracket 22 are on the same central axis. Then, the bottom bracket rod 43 is pulled outward to separate the supporting plate 41 from the bottom end of the columnar accessory. Under the action of the columnar accessory's own gravity, it will fall downward to the upper end of the accessory that has been positioned and fixed on the bottom bracket 22, thereby completing the docking of the two accessories. Finally, the two driving cylinders 71 are started again to contract and drive the control ring 72 to move up a distance to tighten the clamping and fixing effect of the three arc-shaped clamping plates 842 on the columnar accessory.

[0062] Reference Figure 12 As shown, a tilting clamping rod 45 is installed on the lower side of the bottom support rod 43 to limit the bottom support frame 22, and an adapting opening 113 is provided on the control console 11 to communicate with the limiting hole 112 for the tilting clamping rod 45 to pass through. In the initial state, the supporting plate 41 is located directly below the central axis through hole 241, and the tilting clamping rod 45 is clamped on one side of the bottom support frame 22 to limit its rotation, that is, to limit the rotation of the round base 21.

[0063] Continue to refer to Figure 12 As shown, an L-shaped limit rod 46 penetrating the side clamping plate 23 above the bottom support rod 43 is also installed on the upper side of the bottom support rod 43, and a rectangular recess 231 adapted to the L-shaped limit rod 46 is penetrated and opened on the side clamping plate 23 above the bottom support rod 43, and a vertical opening 114 connected with the limit hole 112 and the rectangular recess 231 for the L-shaped limit rod 46 to pass through is penetrated and opened on the control console 11, and a limit socket 47 for inserting one end of the L-shaped limit rod 46 is provided on the upper side of the upper disc 24. The upper disc 24 and the limit socket 47 are fixedly connected.

[0064] When the bottom support rod 43 is pulled outward, one end of the L-shaped limit rod 46 is disengaged from the limit socket 47 to release the rotation restriction on the upper disc 24. After the two accessories are docked and fastened, the assembly seat 12 is rotated 90 degrees toward the accessory, and the staff can perform welding operations on the accurately docked accessories through the welding equipment 13. When the accessories need to be rotated for circumferential welding, it is only necessary to rotate the bottom end of the circular base 21. Since the arc-shaped clamping plate 842 clamps the columnar accessories, the upper disc 24 will rotate synchronously, thereby achieving the purpose of flexibly adjusting the rotation of the clamped and fixed accessories, so that the staff can perform all-round welding on the accessories.

[0065] Embodiment 2:

[0066] Reference Figure 13 and Figure 14As shown in the figure, on the basis of the first embodiment, in order to protect each component in the fixing mechanism 3 and the staff during the welding process, a protection component 9 is further provided on the assembly seat 12. The protection component 9 includes a configuration seat 91 installed on the assembly seat 12. One side of the configuration seat 91 is inserted and installed with a protection bottom plate 93 through an inner strip 92. A plurality of rectangular slots 911 with different heights for inserting and installing the inner strip 92 are opened on the configuration seat 91, which are used to adjust the protection bottom plate 93 to different heights to adapt to the welding heights of different accessories. The protection bottom plate 93 has an arc-shaped bayonet 931. When the assembly seat 12 is rotated 90 degrees towards the accessory, the accessory on the bottom bracket 22 has been adjusted and positioned and is clamped and fixed in the central part. At this time, the accessory will be at the arc-shaped bayonet 931 on the protection bottom plate 93, and the protection bottom plate 93 is above the accessory.

[0067] A U-shaped guard plate 95 is installed on the protection bottom plate 93 in a limited sliding manner through two inner sliding strips 94. A guard plate groove 932 and a sliding strip groove 933 for slidingly installing the U-shaped guard plate 95 and the inner sliding strips 94 are opened on the protection bottom plate 93. Then, the U-shaped guard plate 95 is slid to clamp around the accessory, so as to protect components such as the bottom bracket 22 and the fixing mechanism 3 during welding, and prevent the splashed residues and sparks from falling onto components such as the bottom bracket 22 and the fixing mechanism 3 during the welding process.

[0068] A low-light guard plate 96 is further provided on one side of the protection bottom plate 93 to protect the eyes of the staff and prevent the strong light generated during welding from directly shining into the eyes of the staff.

[0069] The implementation principle of this embodiment is as follows:

[0070] (1) Accessory placement: Place one of the accessories on the bottom bracket 22 between the two T-shaped clamping plates 31, and pass one end of the other columnar accessory through the central axis through hole 241 and place it on the supporting plate 41.

[0071] (2) Clamping respectively: Start the driving motor 34 to operate, drive the two T-shaped clamping plates 31 to slide synchronously towards the center of the bottom bracket 22. Under the action of the coupler 6, the two U-shaped moving rods 51 can be synchronously driven to slide away from the bottom bracket 22. The positioning abutting plate 54 abuts against the inner side of the accessory and will first make a preliminary adjustment to the accessory. The two T-shaped clamping plates 31 sliding synchronously towards the center of the bottom bracket 22 can further make a sliding adjustment to the position of the accessory by abutting. After two position adjustments, the accessory placed on the bottom bracket 22 is quickly positioned, clamped and fixed. Start the two driving cylinders 71 to contract and drive the control ring 72 to move up smoothly, so as to synchronously drive the three clamping rods 42 to rotate towards the columnar accessory. When all three arc-shaped clamping plates 842 are clamped and abutted against the columnar accessory, the position adjustment of the columnar accessory is completed.

[0072] (3) End docking: Subsequently, pull the bottom support rod 43 outwards. Under the action of its own gravity, the columnar fitting will fall downwards to the upper end of the fitting on the bottom support frame 22, and then the two fittings are docked. Finally, start the contraction of the two driving cylinders 71 to drive the control ring 72 to move upwards again to tighten the clamping and fixing effect of the three arc-shaped clamping plates 842 on the columnar fitting.

[0073] (4) Protective welding: Rotate the assembly seat 12 ninety degrees towards the fitting direction, and slide the U-shaped guard plate 95 to clamp around the fitting. To protect components such as the bottom support frame 22 and the fixing mechanism 3 during welding. The staff can rotate the bottom end of the round base 21 while welding the welding joint of the fitting, achieving the effect of being able to flexibly rotate and adjust the clamped and fixed fitting to facilitate the staff to perform all-round welding.
