Description

Technical Field

[0001] The present application relates to the technical field of clamping welding, and in particular to an integrated automatic clamping and welding device for automobile parts. Background Art

[0002] Auto parts refer to the parts, devices and tools used in automobile manufacturing, repair and maintenance. They are the various units that make up the whole car and a product that serves the car. Auto parts welding refers to connecting different parts of auto parts together through welding. This connection method can provide strong support and stability to ensure that the structure of auto parts is firm and reliable. In the processing and production of auto parts, tooling and fixtures are used very frequently. Tooling and fixtures can be used to quickly tighten the workpiece, making the welding and fixing between parts more convenient.

[0003] For example, in the existing Chinese patent with the publication number CN116423135B, a fixture for welding automobile parts is disclosed, which includes a workbench, a mounting groove with a U-shaped cross section is formed in the middle of the workbench, a supporting device for supporting the automobile parts is slidably arranged in the mounting groove, and a clamping device for clamping the automobile parts is respectively arranged in the mounting groove and on both sides of the supporting device. Through the above-mentioned prior art, the supporting device is used to support the automobile parts, and the upper side of the automobile parts is clamped by the clamping device, and then fixed; the supporting device can be moved by the lifting cylinder and the sliding U-shaped frame when supporting the parts, and the height of the supporting platform can be adjusted at the same time. After adjusting the height, the precision support assembly can be used to support the parts of different shapes, that is, it is convenient for the clamping device to clamp and fix the parts, and it is also convenient for processing and fixing them.

[0004] However, the above prior art has the following technical defects: According to the above-mentioned prior art, when processing automobile parts, the automobile parts are supported by the provided support device, and the automobile parts are pressed and fixed by the clamping device; and by providing two sets of support devices and clamping devices, multiple sets of parts can be clamped and fixed during processing, which is convenient for welding. However, since the two sets of support devices and clamping devices are adjusted independently, after the two auto parts are clamped and fixed, the welding points at the joints of the two auto parts are prone to offset, and the support devices and the clamping devices need to be repeatedly adjusted multiple times to align the welding points between the two auto parts, resulting in a long and cumbersome adjustment process.

[0005] Secondly, the above-mentioned device cannot be flipped and adjusted after clamping and fixing the automobile parts, which is not convenient for adjusting the welding position. It can only be applied to a single working environment, has poor flexible adjustment performance, and can not effectively operate the welding space fixation.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-Figure 14 This application is described in further detail.

[0037] The embodiment of the present application discloses an integrated automatic clamping and welding device for automobile parts, which can quickly position and clamp two parts of different shapes, and after clamping and fixing, can flexibly rotate and adjust to facilitate all-round welding of the connection, thereby ensuring the stability of the connection between the parts and meeting the requirements of various working conditions.

[0038] Embodiment 1: Reference Figure 1 As shown, the present application provides an integrated automatic clamping and welding device for automobile parts, including a base 1 and a control panel 11 installed on the upper side of the base 1, a mounting seat 12 is rotatably provided on one side of the control panel 11, a welding device 13 is provided in the mounting seat 12, and a positioning clamping device 2 is provided on the control panel 11 for automatically positioning, clamping and fixing two parts of different shapes, so that the two parts can be quickly and accurately docked. Then the staff can rotate the mounting seat 12 toward the middle of the control panel 11, and weld the two parts through the welding device 13. The welding device 13 in this embodiment is preferably composed of an electric welder, a welding clamp and a welding rod. Since this is an existing well-known technology, it will not be described in detail here.

[0039] Reference Figure 2 and Figure 3 As shown, specifically, the positioning and clamping device 2 includes a round base 21 that penetrates and rotates in the middle of the control console 11. The control console 11 is penetrated with a middle hole 111 for the round base 21 to be rotatably installed. It should be noted that the bottom of the round base 21 penetrates downward and extends out of the middle hole 111, so that the staff can rotate the round base 21 when needed. A bottom bracket 22 is installed in the middle of the upper side of the round base 21. The bottom bracket 22 and the round base 21 are fixedly connected, and the center point of the round base 21 and the center point of the bottom bracket 22 are on the same central axis; an upper disc 24 is provided on the control console 11 above the bottom bracket 22 through two side clamps 23 to limit rotation, and the upper disc 24 has a central axis through hole 241. A fixing mechanism 3 is provided on the bottom bracket 22 and the round base 21, and a clamping unit 4 is provided on the lower side of the upper disc 24. The fixing mechanism 3 and the clamping unit 4 can respectively position and clamp accessories of different shapes.

[0040] When in use, first one of the accessories is placed in the fixing mechanism 3 of the bottom bracket 22, and the other columnar accessory is placed in the clamping unit 4 through the central axis through hole 241. Then, under the operation of the fixing mechanism 3 and the clamping unit 4, the two accessories can be quickly positioned and clamped to ensure that the two accessories can be accurately docked. After the docking is completed, the staff can perform all-round welding operations on the connection between the two accessories through the welding equipment 13.

[0041] Reference 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.

[0042] 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.

[0043] 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.

[0044] The side spring 55 has a relatively large force. Although the positioning plate 54 is slidably connected to the U-shaped shift rod 51 through the two square connecting rods 53, due to the presence of the side spring 55, when the U-shaped shift rod 51 is driven to slide, it will synchronously drive the positioning plate 54 to move until the positioning plate 54 is restrained and cannot continue to move. At this time, the side spring 55 is compressed, and the U-shaped shift rod 51 can continue to slide under force. The linkage 6 is arranged in the middle of the round base 21, and is used to be driven by the sliding movement of the T-shaped clamping plate 31 to control the synchronous sliding of the two U-shaped shift rods 51.

[0045] Reference Figure 6 and Figure 7 As shown, since it is necessary to drive the U-shaped shift rod 51 in linkage while the T-shaped clamp plate 31 moves, the linkage 6 includes an internal seat 61 and an L-shaped rack 62; the internal seat 61 is installed in the middle of the upper side of the round base 21 and is located between the two U-shaped shift rods 51, and a transmission screw 63 that penetrates the two positioning plates 54 and is threaded through the two U-shaped shift rods 51 is rotatably provided on the internal seat 61, and a circular through hole 541 for the transmission screw 63 to penetrate is opened on the positioning plate 54, and a threaded through hole 512 that is compatible with the transmission screw 63 is threadedly opened on the U-shaped shift rod 51; when the transmission screw 63 is rotated under force, the two U-shaped shift rods 51 can be synchronously driven to slide in cooperation with the threaded through hole 512 opened on the U-shaped shift rod 51.

[0046] One end of the L-shaped rack 62 penetrates the bottom bracket 22 and is installed on the lower side of the T-shaped clamping plate 31. The bottom bracket 22 is provided with a rectangular sliding opening 223 connected to the T-shaped sliding groove 221 for the L-shaped rack 62 to penetrate and install. The middle part of the transmission screw 63 is sleeved with a driving gear 64 that meshes with the L-shaped rack 62. When the T-shaped clamping plate 31 is driven by the driving motor 34 to slide toward the center of the bottom bracket 22, the driving gear 64 is driven by the L-shaped rack 62 to drive the transmission screw 63 to rotate; the rotating transmission screw 63, in cooperation with the threaded through hole 512, can synchronously drive the two U-shaped shift rods 51 to slide away from the bottom bracket 22 and synchronously drive the positioning plate 54 to move until the two positioning plates 54 both contact the inner side of the accessory on the bottom bracket 22. Since the force of the side spring 55 is relatively large, when the positioning plates 54 contact the inner side of the accessory, the position angle of the accessory will be adjusted first, and under the synchronous contact adjustment of the two positioning plates 54, the center point of the accessory and the center point of the bottom bracket 22 will be on the same plane.

[0047] 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.

[0048] Reference Figure 8 and Fig. 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.

[0049] 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.

[0050] Continue to refer to Fig. 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.

[0051] Reference Fig.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.

[0052] 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.

[0053] Reference Fig.10 and Fig.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.

[0054] 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.

[0055] Reference Fig.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.

[0056] Continue to refer to Fig.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.

[0057] 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.

[0058] Embodiment 2: Reference Fig.13 and Fig.14As shown, on the basis of the first embodiment, in order to protect the various components in the fixing mechanism 3 and the staff during the welding process, a protective component 9 is further provided on the assembly seat 12, and the protective component 9 includes a configuration seat 91 installed on the assembly seat 12, and a protective bottom plate 93 is installed on one side of the configuration seat 91 through the inner strip plate 92. The configuration seat 91 is provided with a plurality of rectangular slots 911 of different heights for the inner strip plate 92 to be inserted and installed, which are used to adjust the protective bottom plate 93 to different heights to adapt to different accessory welding heights. The protective bottom plate 93 has an arc-shaped bayonet 931. When the assembly seat 12 is rotated 90 degrees toward the accessory, the accessory on the bottom bracket 22 is clamped and fixed in the center due to the adjusted positioning. At this time, the accessory will be at the arc-shaped bayonet 931 on the protective bottom plate 93, and the protective bottom plate 93 will be above the accessory.

[0059] A U-shaped guard plate 95 is slidably mounted on the protective bottom plate 93 through two inner slide bars 94, and a guard plate groove 932 and a slide bar groove 933 are provided on the protective bottom plate 93 for slidingly mounting the U-shaped guard plate 95 and the inner slide bar 94, and then the U-shaped guard plate 95 is slid and clamped around the accessories, so as to protect the bottom bracket 22 and the fixing mechanism 3 and other components during welding, and prevent the residual sparks splashed during welding from falling on the bottom bracket 22 and the fixing mechanism 3 and other components.

[0060] A weak light shield 96 is also provided on one side of the protective bottom plate 93 to protect the eyes of the workers and prevent the strong light generated during welding from directly shining into the eyes of the workers.

[0061] The implementation principle of this embodiment is: (1) Accessory placement: Place one of the accessories on the bottom bracket 22 between the two T-shaped clamps 31, and place one end of the other columnar accessory through the central axis through hole 241 on the supporting plate 41.

[0062] (2) Clamping separately: Start the driving motor 34 to drive the two T-shaped clamps 31 to slide synchronously toward the center of the bottom bracket 22. Under the action of the linkage 6, the two U-shaped shift rods 51 can be synchronously driven to slide away from the bottom bracket 22. The positioning plate 54 contacts the inner side of the accessory to make a preliminary adjustment to the accessory. The two T-shaped clamps 31 synchronously slide toward the center of the bottom bracket 22 to further adjust the position of the accessory. After two position adjustments, the accessory placed on the bottom bracket 22 can be quickly positioned, clamped and fixed. Start the two driving cylinders 71 to retract the driving control ring 72 and move it upward smoothly, so as to synchronously drive the three clamping rods 42 to rotate toward the columnar accessory. When the three arc-shaped clamps 842 are all clamped and contacted on the columnar accessory, the position adjustment of the columnar accessory is completed.

[0063] (3) End docking: The bottom support rod 43 is then pulled outward, and the columnar accessory falls downward to the upper end of the accessory on the bottom support frame 22 under the action of its own gravity, and the two accessories are then docked. Finally, the two driving cylinders 71 are activated to contract and drive the control ring 72 to move upward again to tighten the three arc-shaped clamping plates 842 to clamp and fix the columnar accessory.

[0064] (4) Protective welding: Rotate the assembly seat 12 90 degrees toward the accessory, and slide the U-shaped guard plate 95 around the accessory to protect the bottom bracket 22 and the fixing mechanism 3 during welding. The worker can rotate the bottom end of the round base 21 while welding the accessory, so that the accessory can be flexibly rotated and adjusted after being clamped and fixed, so that the worker can perform all-round welding.

[0065] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
