Description

Technical Field

[0001] This invention belongs to the field of motorcycle manufacturing technology, specifically a motorcycle bumper welding and assembly equipment. Background Technology

[0002] Motorcycle bumpers are an important component of motorcycles. Existing motorcycle bumpers typically consist of an outer bumper with a U-shaped structure and a straight inner bumper fixed to the inside of the outer bumper.

[0003] Currently, motorcycle U-shaped outer bars and straight inner bars are usually fixed by welding. Since the contact surface between the straight inner bar and the U-shaped outer bar has an irregular curved structure, welding requires manual operation of a welding torch, which must be held and moved around the irregular curve to achieve the welding purpose. However, this welding method is relatively traditional, and the welding torch is prone to deviating from the irregular curve when the welder moves it, thus affecting the welding quality. Therefore, the existing welding between motorcycle U-shaped outer bars and straight inner bars relies heavily on the welding skills of the welder, and incomplete welds or missed welds are prone to occur during welding. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a motorcycle bumper welding and assembly equipment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A motorcycle bumper welding and assembly device includes a welding table, a U-shaped bumper body, a straight inner bumper, a welding torch, and a drive assembly. A U-shaped positioning block is fixedly installed on the upper part of the welding platform. The U-shaped positioning block is used to position the inner U-shaped bar. When one end of the straight inner bar contacts the inner wall of the U-shaped bar, it forms a first irregular curve. The drive assembly is movably mounted on the straight inner bar and is used to drive the welding torch to rotate along the irregular curve trajectory in order to weld the straight inner bar to the inside of the U-shaped bar.

[0006] As a further improvement of the present invention: the driving component includes a positioning sleeve. The positioning sleeve has a first curved groove on its side wall, and the first curved groove follows the same trend as the irregular curve. The welding torch is tilted towards the irregular curve. A telescopic rod is fixedly installed on the side wall of the welding torch. A support sleeve is externally sleeved on the end of the telescopic rod away from the welding torch. A sliding rod is installed through the telescopic rod. One end of the sliding rod extends into the first curved groove and slides in cooperation with the first curved groove. The support sleeve is located outside the positioning sleeve and can rotate circumferentially around the positioning sleeve.

[0007] As a further improvement of the present invention: an elastic element is provided inside the support sleeve, and the elastic element is used to provide elastic tension to the positioning rod.

[0008] As a further improvement of the present invention: an annular slide rail is fixedly provided on the outer wall of the positioning sleeve, a slider is slidably provided on the annular slide rail, a rotating shaft is fixedly provided on the side wall of the support sleeve, and the end of the rotating shaft away from the support sleeve is connected to the slider.

[0009] As a further improvement to the present invention: when the other end of the straight inner bar contacts the inner wall of the U-shaped bar, a second irregular curve is formed. The slide rod has an external thread on its outer wall, and the slide rod engages with the telescopic rod via the external thread. The end of the rotating shaft away from the support sleeve is rotatably connected to the slider. The outer wall of the positioning sleeve is also provided with a second curved groove, which is distributed opposite to the first curved groove, and the trend of the second curved groove is consistent with that of the second irregular curve.

[0010] As a further improvement of the present invention: the positioning sleeve includes a first semi-circular shell and a second semi-circular shell, the first semi-circular shell and the second semi-circular shell are oppositely distributed and hinged to each other, and ear plates are fixedly provided on the outer walls of the first semi-circular shell and the second semi-circular shell, and the two sets of ear plates are connected by a second locking bolt. The first curved groove, the second curved groove, and half of the annular slide rail are located on the outer wall of the first semi-circular housing, and the other half of the first curved groove, the second curved groove, and the annular slide rail are located on the outer wall of the second semi-circular housing.

[0011] As a further improvement of the present invention: a first locking bolt is also provided on the side wall of the U-shaped positioning block.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, when it is necessary to weld the straight inner bar constituting the motorcycle bumper to the inside of the U-shaped bar, the U-shaped bar can be embedded inside the U-shaped positioning block to achieve positioning of the U-shaped bar. Then, the straight inner bar is placed inside the U-shaped bar so that one end of the straight inner bar contacts the inner wall of the U-shaped bar. At this time, the contact position between the one end of the straight inner bar and the U-shaped bar forms a first irregular curve. Subsequently, the drive assembly is installed on the straight inner bar, and the drive assembly drives the welding gun to rotate along the trajectory of the first irregular curve, thereby welding one end of the straight inner bar and the U-shaped bar together. Compared with the prior art, when welding the straight inner bar constituting the motorcycle bumper to the inside of the U-shaped bar, the welding gun can be accurately driven to move along the irregular curve trajectory formed when the end of the straight inner bar contacts the U-shaped bar, thereby achieving full welding of the straight inner bar and the U-shaped bar, which has the advantages of good welding effect and high welding quality.

Detailed Implementation

[0014] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0015] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] Please see Figure 1 as well as Figure 2 This embodiment provides a motorcycle bumper welding and assembly equipment, including a welding table 10, a U-shaped bumper body 20, a straight inner bumper 30, a welding torch 40, and a drive assembly 50. A U-shaped positioning block 101 is fixedly installed on the upper part of the welding table 10. The U-shaped positioning block 101 is used to position the U-shaped inner bumper 20. When one end of the straight inner bumper 30 contacts the inner wall of the U-shaped bumper body 20, it forms a first irregular curve. The drive assembly 50 is movably installed on the straight inner bumper 30 and is used to drive the welding torch 40 to rotate along the irregular curve trajectory so as to weld the straight inner bumper 30 to the inner side of the U-shaped bumper body 20.

[0017] When it is necessary to weld the straight inner bar 30, which constitutes the motorcycle bumper, to the inside of the U-shaped bar body 20, the U-shaped bar body 20 can be embedded into the inside of the U-shaped positioning block 101 to achieve the positioning of the U-shaped bar body 20. Then, the straight inner bar 30 is placed inside the U-shaped bar body 20, so that one end of the straight inner bar 30 contacts the inner wall of the U-shaped bar body 20. At this time, the contact position between one end of the straight inner bar 30 and the U-shaped bar body 20 forms a first irregular curve. Subsequently, the drive assembly 50 is installed on the straight inner bar 30, and the welding gun 40 is driven to rotate along the trajectory of the first irregular curve by the drive assembly 50, thereby welding one end of the straight inner bar 30 and the U-shaped bar body 20 together.

[0018] Please see Figure 3 In one embodiment, the drive assembly 50 includes a positioning sleeve 501. A first curved groove 502 is formed on the side wall of the positioning sleeve 501. The first curved groove 502 is consistent with the trend of the irregular curve. The welding torch 40 is tilted towards the irregular curve. A telescopic rod 401 is fixedly provided on the side wall of the welding torch 40. A support sleeve 403 is telescopically sleeved on the end of the telescopic rod 401 away from the welding torch 40. A sliding rod 402 is provided through the telescopic rod 401. One end of the sliding rod 402 extends into the first curved groove 502 and slides in cooperation with the first curved groove 502. The support sleeve 403 is provided outside the positioning sleeve 501 and can rotate circumferentially around the positioning sleeve 501.

[0019] After one end of the straight inner bar 30 contacts the inner wall of the U-shaped bar 20 and forms the first irregular curve, the positioning sleeve 501 can be fitted onto the outside of the straight inner bar 30. Then, the worker holds the support sleeve 403 and makes the support sleeve 403 rotate circumferentially around the positioning sleeve 501. When the support sleeve 403 rotates, it drives the telescopic rod 401 and the welding torch 40 to rotate circumferentially synchronously. When the telescopic rod 401 rotates circumferentially, it drives the sliding rod 402 to slide one end of the sliding rod 402 along the inside of the first curved groove 502. The curve groove 502 follows the same trend as the irregular curve. Therefore, when the slide rod 402 slides along the inside of the first curve groove 502, it can cause the telescopic rod 401 to expand and contract adaptively relative to the support sleeve 403, and thus cause the welding torch 40 to expand and contract adaptively. In this way, when the support sleeve 403 rotates around the positioning sleeve 501, the movement trajectory of the welding torch 40 is consistent with the first irregular curve formed when one end of the straight inner bar 30 contacts the U-shaped bar 20, and thus the straight inner bar 30 and the U-shaped bar 20 are fully welded.

[0020] Please see Figure 3 In one embodiment, an elastic element 404 is provided inside the support sleeve 403. The elastic element 404 is used to provide elastic tension to the positioning rod 401, so that when the telescopic rod 401 expands and contracts relative to the support sleeve 403, the elastic element 404 expands and contracts accordingly, so as to improve the cooperation effect between the slide rod 402 and the first curved groove 502.

[0021] Please see Figure 3 In one embodiment, an annular slide rail 503 is fixedly provided on the outer wall of the positioning sleeve 501, and a slider 504 is slidably provided on the annular slide rail 503. A rotating shaft 405 is fixedly provided on the side wall of the support sleeve 403, and one end of the rotating shaft 405 away from the support sleeve 403 is connected to the slider 504.

[0022] When the staff holds the support sleeve 403 and drives the support sleeve 403 to rotate around the positioning sleeve 501, the slider 504 slides along the annular slide rail 503.

[0023] Please see Figure 3 In one embodiment, when the other end of the straight inner bar 30 contacts the inner wall of the U-shaped bar 20, a second irregular curve is formed. The outer wall of the slide bar 402 is provided with an external thread, and the slide bar 402 is threadedly engaged with the telescopic rod 401 through the external thread. The end of the rotating shaft 504 away from the support sleeve 403 is rotatably connected to the slider 504. The outer wall of the positioning sleeve 501 is also provided with a second curved groove 505. The second curved groove 505 is distributed opposite to the first curved groove 502, and the trend of the second curved groove 505 is consistent with that of the second irregular curve.

[0024] After the welding torch 40 rotates around the straight inner bar 30 for one revolution to complete the welding of one end of the straight inner bar 30 to the inner wall of the U-shaped bar body 20, the operator can rotate the slide rod 402. Through the threaded engagement of the external thread and the telescopic rod 401, the slide rod 402 can move relative to the telescopic rod 401. When the slide rod 402 moves, one end of it retracts from the inside of the first curved groove 502. Then, the operator holds the support sleeve 403 and rotates it 180° relative to the slider 504 with the pivot 504 of the support sleeve 403 as the rotation axis. When the support sleeve 403 rotates 180°, it drives the telescopic rod 401, the slide rod 402, and the welding torch 40 to rotate 180°. Then, the operator rotates the slide rod 402 in the opposite direction, causing the slide rod 402 to move in the opposite direction relative to the telescopic rod 401. When the slide rod 402 moves in the opposite direction, one end of it extends to the second curved groove 502. Inside the groove 505, the positioning sleeve 501 is then slid along the length of the straight inner bar 30 to adjust the positioning sleeve 501 to the other end of the straight inner bar 30. When the positioning sleeve 501 slides to the other end of the straight inner bar 30, the welding torch 40 tilts towards the second irregular curve. Then, the worker holds the support tube 403 again to make the support tube 403 rotate around the positioning sleeve 501, thereby driving the welding torch 40 to rotate around the circumference. When the welding torch 40 rotates around the circumference, the sliding cooperation between the slide rod 402 and the second curved groove 505, as well as the telescopic cooperation between the telescopic rod 401 and the support tube 403, can make the movement trajectory of the welding torch 40 consistent with the second irregular curve, and then weld the second irregular curve to weld the other end of the straight inner bar 30 to the U-shaped bar body 20 as one piece.

[0025] Please see Figure 4 In one embodiment, the positioning sleeve 501 includes a first semi-circular shell 5011 and a second semi-circular shell 5012. The first semi-circular shell 5011 and the second semi-circular shell 5012 are distributed opposite to each other and hinged to each other. Ear plates 5013 are fixedly provided on the outer walls of the first semi-circular shell 5011 and the second semi-circular shell 5012. The two sets of ear plates 5013 are connected by a second locking bolt 5014. Half of the first curved groove 502, the second curved groove 505 and the annular slide rail 503 are located on the outer wall of the first semi-circular shell 5011, and the other half of the first curved groove 502, the second curved groove 505 and the annular slide rail 503 are located on the outer wall of the second semi-circular shell 5012.

[0026] Initially, the first semi-circular housing 5011 and the second semi-circular housing 5012 are in the open state. When it is necessary to weld the straight inner bar 30 to the U-shaped rod 20, the first semi-circular housing 5011 and the second semi-circular housing 5012 can be clamped around the outside of the straight inner bar 30, and the first semi-circular housing 5011 and the second semi-circular housing 5012 can be locked around the outside of the straight inner bar 30 by cooperating with the ear plate 5013 using the second locking bolt 5014. After the first semi-circular housing 5011 and the second semi-circular housing 5012 are locked around the outside of the straight inner bar 30, the two parts of the first curved groove 502 are connected end to end to form a complete curved groove structure, the two parts of the second curved groove 505 are connected end to end to form a complete curved groove structure, and the two parts of the annular slide rail 503 are connected end to end to form a complete curved groove structure. This is for the straight inner bar 30... When welding one end of the U-shaped bar 20 to the inner wall, the slide bar 402 slides circumferentially along the inside of the first curved groove 502, and the slider 504 slides circumferentially along the annular slide rail 503. After the welding torch 40 finishes welding the first irregular curve, the worker loosens the second locking bolt 5014, and then slides the first semi-circular shell 5011 and the second semi-circular shell 5012 along the straight inner bar 30 to a position close to the other end of the straight inner bar 30. Then, the worker tightens the second locking bolt 5014 again to fix the first semi-circular shell 5011 and the second semi-circular shell 5012. After the welding torch 40 finishes welding the second irregular curve, the worker removes the second locking bolt 5014 from the ear plate 5013, and then removes the first semi-circular shell 5011 and the second semi-circular shell 5012 from the outside of the straight inner bar 30.

[0027] In one embodiment, the elastic element 404 can be a spring or a metal sheet, and there is no limitation here.

[0028] Please see Figure 2 In one embodiment, a first locking bolt 102 is also provided on the side wall of the U-shaped positioning block 101.

[0029] After the U-shaped bar 20 is embedded inside the U-shaped positioning block 101, the operator can tighten the first locking bolt 102 to push the U-shaped bar 20 against the inner wall of the U-shaped positioning block 102, thereby fixing the U-shaped bar 20 and improving the stability during subsequent welding.

[0030] In this embodiment of the invention, when it is necessary to weld the straight inner bar 30 constituting the motorcycle bumper to the inner side of the U-shaped bar body 20, the U-shaped bar body 20 can be embedded into the inner side of the U-shaped positioning block 101 to achieve positioning of the U-shaped bar body 20. Then, the straight inner bar 30 is placed inside the U-shaped bar body 20, so that one end of the straight inner bar 30 contacts the inner wall of the U-shaped bar body 20. At this time, the contact position between one end of the straight inner bar 30 and the U-shaped bar body 20 forms a first irregular curve. Subsequently, the drive assembly 50 is installed on the straight inner bar 30, and the drive assembly 50 is used to drive the motorcycle bumper. The moving component 50 drives the welding torch 40 to rotate along the first irregular curve trajectory, thereby welding one end of the straight inner bar 30 and the U-shaped bar 20 together. Compared with the prior art, when welding the straight inner bar 30, which constitutes the motorcycle bumper, to the inside of the U-shaped bar 20, the welding torch 40 can be accurately driven to move along the irregular curve trajectory formed when the end of the straight inner bar 30 contacts the U-shaped bar 20, thereby realizing the full welding of the straight inner bar 30 and the U-shaped bar 20, which has the advantages of good welding effect and high welding quality.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
