Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and particularly to an arc welding fixing tooling for a motorcycle fuel tank. Background Art

[0002] In the arc welding of a motorcycle fuel tank, in order to effectively control the dimensional deviation of the product, improve the machining accuracy and interchangeability of parts, operators usually need to use high-precision tooling fixtures to achieve rigid constraints during the welding process, ensuring that the fuel tank is not prone to welding errors due to movement during welding, and improving the welding qualification rate and subsequent assembly efficiency.

[0003] In order to avoid scratching the outer wall of the fuel tank, the existing arc welding fixing tooling for motorcycle fuel tanks usually installs a rubber sleeve structure at the clamping contact part. However, with long-term use, the rubber sleeve is prone to aging, deformation or even cracking due to frequent extrusion, resulting in a decline in the protection performance. In addition, the rubber sleeve is mostly installed in a fixed manner (such as adhesively bonding or snap-fitting), and manual disassembly requires prying with tools or destructive removal, which takes a long time for a single replacement. This not only affects the production line rhythm but also may cause damage to the fixture contact surface due to repeated disassembly and assembly. Summary of the Invention

[0004] The present invention relates to an arc welding fixing tooling for a motorcycle fuel tank, which modularizes the installation socket and the flexible chuck. When the fixing tooling enters the non-use state, the flexible chuck automatically lacks rigid fixation, reducing the replacement time for a single chuck. Moreover, the modular design allows for independent replacement of different specifications of chucks to adapt to fuel tanks of multiple vehicle models.

[0005] In the first aspect of the present invention, an arc welding fixing tooling for a motorcycle fuel tank is provided, which specifically includes: a main body, on the front and rear sides inside the main body, there are fixedly installed guide plates; a sliding seat is sleeved and slidably installed on the guide plates; a fixed sliding plate is fixedly installed inside the sliding seat; a support column is fixedly installed inside the fixed sliding plate; a guide column is fixedly installed on the support column; a transmission sliding seat is sleeved and slidably installed on the guide column; a stress block is fixedly installed on the outer side of the inner end of the transmission sliding seat; a pushing member is slidably installed inside the transmission sliding seat; at the four corners inside the fixed sliding plate, there are fixedly installed fixing seats; an adjusting rail is fixedly installed at the front end of the fixing seat; an adjusting bolt is rotatably installed inside the fixing seat; an adjusting part is slidably installed on the adjusting rail; an installation groove is opened at the inner top of the adjusting part; an installation socket is slidably installed inside the installation groove; a limiting hole is opened at the outer end of the installation socket; a flexible chuck is fixedly installed at the inner end of the installation socket; a transmission column is slidably installed at the inner end inside the adjusting part; a transmission groove is opened on the circumferential outer wall of the transmission column.

[0006] Further, support vertical plates are fixedly installed in a left-right symmetric arrangement at the top of the main body; a support horizontal plate is fixedly installed inside the support vertical plate.

[0007] Further, a push plate is fixedly installed at the inner end of the support horizontal plate, and a welding station is fixedly installed at the center position of the top of the main body.

[0008] Further, a driving lead screw is rotatably installed at the bottom of the welding station; a driving motor is fixedly installed on the right side of the top of the main body; the output shaft of the driving motor is fixedly connected to the right end of the driving lead screw.

[0009] Further, a connecting plate is fixedly installed on the sliding seat; two opposite threads are provided on the driving lead screw, and the driving lead screw is connected to the connecting plate through the threads.

[0010] Further, a spring A is jointly installed between the inner side of the transmission sliding seat and the outer side of the support column; the top outer corner position of the force-bearing block is of an inclined structure.

[0011] Further, when the fixed sliding plate is in the non-inward movement state, the inclined surface of the force-bearing block will be pushed by the push plate; the push member is of an L-shaped structure; the adjusting part is connected to the adjusting bolt through threads.

[0012] Further, an adjusting block is fixedly installed at the outer end of the adjusting bolt, and a round hole is provided on each edge surface of the adjusting block; the inner end of the push member is also slidably installed inside the adjusting part.

[0013] Further, the installation groove is of a T-shaped structure; the installation socket is of a T-shaped structure; the inner end of the transmission groove is of an inclined structure.

[0014] Further, an embedding disc is fixedly installed at the outer end of the transmission column; the embedding disc is of a disc-shaped structure; a spring B is jointly installed between the inner side of the embedding disc and the inside of the adjusting part.

[0015] The present invention provides a motorcycle fuel tank arc welding fixing tooling, which has the following beneficial effects: (1) By rotating the adjusting block with a tool, driving the adjusting bolt to drive the adjusting part and the flexible chuck to move inward synchronously to complete the basic position adjustment. Through the position adjustment of the four flexible chucks, they can fit the outer wall of the fuel tank on the basis of the same drive, ensuring that the fitting gaps between each chuck and the outer wall of the fuel tank are uniform, effectively avoiding virtual soldering or fuel tank deformation caused by uneven local stress during welding, and significantly improving the clamping stability.

[0016] (2) When the four flexible chucks gradually approach the motorcycle fuel tank and are about to clamp, the force-receiving block disengages from the pushing area of the pushing plate. The transmission slide seat automatically moves outward under the elastic action of spring A, driving the pushing member to displace synchronously. During the outward movement of the pushing member, the inclined surface of the pushing transmission groove drives the transmission column to insert inward into the limiting hole, forming a mechanical lock, realizing the rigid fixation of the mounting socket and the flexible chuck on the adjusting part, ensuring the fixation effect on the fuel tank during the welding process, and effectively guaranteeing the clamping stability and production quality.

[0017] (3) After welding is completed, the driving motor rotates reversely to drive the lead screw, causing the flexible chuck to move outward. The force-receiving block re-enters the area of the pushing plate, and the pushing plate drives the transmission slide seat to move inward through the action of the inclined surface, releasing the pushing of the pushing member on the transmission groove, causing the transmission column to disengage from the limiting hole, enabling the flexible chuck to be disassembled only by sliding, realizing tool-free and rapid disassembly. After the modular-designed mounting socket and the flexible chuck are separated in this way, not only can different specifications of chucks be independently replaced to adapt to fuel tanks of multiple vehicle models, but also the replacement time of a single chuck is extremely short, greatly improving the production line changeover efficiency and welding efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 8 : Embodiment 1: The present invention provides a fixed tool for arc welding of a motorcycle fuel tank, comprising: a main body 1, with guide plates 8 fixedly installed on the front and rear sides inside the main body 1; a sliding seat 9 is sleeved and slidably installed on the guide plates 8; a fixed slide plate 11 is fixedly installed inside the sliding seat 9; a support column 12 is fixedly installed inside the fixed slide plate 11; a guide column 13 is fixedly installed on the support column 12; a driving slide seat 14 is sleeved and slidably installed on the guide column 13; a force-receiving block 16 is fixedly installed on the outer side of the inner end of the driving slide seat 14; a pushing member 17 is slidably installed inside the driving slide seat 14; fixing seats 18 are fixedly installed at the four corners inside the fixed slide plate 11; an adjusting rail 19 is fixedly installed at the front end of the fixing seat 18; an adjusting bolt 20 is rotatably installed inside the fixing seat 18; an adjusting part 22 is slidably installed on the adjusting rail 19; an installation groove 23 is opened at the inner top of the adjusting part 22; an installation socket 24 is slidably installed inside the installation groove 23; a limiting hole 25 is opened at the outer end of the installation socket 24; a flexible chuck 26 is fixedly installed at the inner end of the installation socket 24; a transmission column 27 is slidably installed at the inner end inside the adjusting part 22; a transmission groove 28 is opened on the circumferential outer wall of the transmission column 27. According to the specific shape of the outer wall of the motorcycle fuel tank, the basic positions of a plurality of flexible chucks 26 are adaptively and selectively adjusted. By rotating the adjusting block 21 with a tool, the adjusting bolt 20 is rotated, and the adjusting bolt 20 drives the adjusting part 22 and the flexible chuck 26 to move inwards through rotation, adjusting the basic positions of the flexible chucks 26, ensuring that when fixed, a plurality of flexible chucks 26 can accurately fit on the outer wall of the motorcycle fuel tank under the basis of the same drive, and when adjusting, the pushing member 17 will also move along the driving slide seat 14, so that the pushing end of the pushing member 17 still aligns with the transmission groove 28, and the problem of the offset of the pushing position of the pushing member 17 caused by the adjustment will not occur.

[0023] Embodiment 2: On the basis of Embodiment 1, support vertical plates 5 are fixedly installed at the top of the main body 1 in a left-right symmetrical arrangement; a support horizontal plate 6 is fixedly installed inside the support vertical plate 5; a push plate 7 is fixedly installed at the inner end of the support horizontal plate 6; a welding station 2 is fixedly installed at the center position of the top of the main body 1; a driving lead screw 3 is rotatably installed at the bottom of the welding station 2; a driving motor 4 is fixedly installed on the right side of the top of the main body 1; the output shaft of the driving motor 4 is fixedly connected to the right end of the driving lead screw 3; a connecting plate 10 is fixedly installed on the sliding seat 9; two opposite threads are provided on the driving lead screw 3, and the driving lead screw 3 is connected to the connecting plate 10 through the threads. By placing the fuel tank to be welded on the welding station 2, then starting the driving motor 4 to drive the driving lead screw 3 to rotate, the driving lead screw 3 drives two connecting plates 10, two groups of sliding seats 9 and two groups of flexible chucks 26 to move relatively inward, so that the four flexible chucks 26 gradually approach the motorcycle fuel tank. During the approaching process, the force receiving block 16 disengages from the pushing area of the push plate 7, so that the transmission sliding seat 14 drives the pushing member 17 to move outward under the action of the spring A15, so that the pushing member 17 pushes the inclined surface of the transmission groove 28, and it is forced to drive the transmission column 27 to move inward, so that the transmission column 27 is inserted into the limiting hole 25, ensuring that when fixing next, the mounting socket 24 and the flexible chuck 26 can be stably fixed on the adjusting part 22, ensuring that the flexible chuck 26 is stable enough when fixed.

[0024] Embodiment 3: On the basis of Embodiment 2, a spring A15 is jointly embedded between the inner side of the transmission sliding seat 14 and the outer side of the support column 12; the top outer corner position of the force receiving block 16 is of an inclined structure; when the fixed sliding plate 11 is in the non-inward moving state, the inclined surface of the force receiving block 16 will be pushed by the push plate 7; the pushing member 17 is of an L-shaped structure; the adjusting part 22 is connected to the adjusting bolt 20 through threads; an adjusting block 21 is fixedly installed at the outer end of the adjusting bolt 20, and a round hole is provided on each edge surface of the adjusting block 21; the inner end of the pushing member 17 is also slidably installed inside the adjusting part 22; the installation groove 23 is of a T-shaped structure; the mounting socket 24 is of a T-shaped structure; the inner end of the transmission groove 28 is of an inclined structure; a clamping disc 29 is fixedly installed at the outer end of the transmission column 27; the clamping disc 29 is of a disc-shaped structure; a spring B30 is jointly embedded between the inner side of the clamping disc 29 and the inside of the adjusting part 22. By driving the driving lead screw 3 to reverse by the driving motor 4, the plurality of flexible chucks 26 move outward. During the outward movement, the force receiving block 16 enters the pushing area of the push plate 7 again, so that the push plate 7 pushes the inclined surface of the force receiving block 16, driving the transmission sliding seat 14 and the pushing member 17 to move inward, so that the pushing member 17 cancels the pushing of the inclined surface of the transmission groove 28 by moving inward, so that the transmission column 27 disengages from the limiting hole 25, and the mounting socket 24 and the flexible chuck 26 lack rigid fixation. Thus, when the fixing tooling is not in use, the flexible chuck 26 can be disassembled, assembled and replaced conveniently by sliding.

[0025] Working principle of this embodiment: When in use, first, according to the specific shape of the outer wall of the motorcycle fuel tank, the basic positions of multiple flexible chucks 26 can be adaptively and selectively adjusted. By rotating the adjusting block 21 with a tool, the adjusting bolt 20 is driven to rotate, and the adjusting bolt 20 drives the adjusting part 22 and the flexible chuck 26 to move inwards through rotation, adjusting the basic positions of the flexible chucks 26, ensuring that when fixed, the multiple flexible chucks 26 can accurately fit on the outer wall of the motorcycle fuel tank under the same drive. And when adjusting, the pushing member 17 will also move along the transmission slide 14, so that the pushing end of the pushing member 17 still aligns with the transmission slot 28, and the problem of the offset of the pushing position of the pushing member 17 caused by the adjustment will not occur. After the adjustment is completed, the fuel tank to be welded is placed on the welding station 2, and then the driving motor 4 is started to drive the driving screw 3 to rotate. The driving screw 3 drives the two connecting plates 10, two groups of sliding seats 9 and two groups of flexible chucks 26 to move relatively inwards through rotation, so that the four flexible chucks 26 gradually approach the motorcycle fuel tank. During the approaching process, the force receiving block 16 breaks away from the pushing area of the pushing plate 7, so that the transmission slide 14 drives the pushing member 17 to move outwards under the action of the spring A15, and the pushing member 17 pushes the inclined surface of the transmission slot 28, and the force makes the transmission column 27 move inwards, so that the transmission column 27 is inserted into the internal limiting hole 25, ensuring that when fixed next, the mounting socket 24 and the flexible chuck 26 can be stably fixed on the adjusting part 22, ensuring that the flexible chuck 26 is stable enough when fixed. After the arc welding of the motorcycle fuel tank is completed, the driving motor 4 drives the driving screw 3 to reverse, so that the multiple flexible chucks 26 move outwards. During the outward movement, the force receiving block 16 enters the pushing area of the pushing plate 7 again, so that the pushing plate 7 pushes the inclined surface of the force receiving block 16, driving the transmission slide 14 and the pushing member 17 to move inwards, and the pushing member 17 cancels the pushing on the inclined surface of the transmission slot 28 through inward movement, so that the transmission column 27 disengages from the limiting hole 25, and the mounting socket 24 and the flexible chuck 26 lack hard fixation. Thus, when the fixing tooling is not in use, the flexible chuck 26 can be disassembled, assembled and replaced conveniently by sliding.
