Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a welding apparatus for processing bicycle parts. Background Technology

[0002] The front fork is a very important structural component of a bicycle. It can form the bicycle's guiding system with other bicycle components, and it is also a key component of the bicycle's shock absorption system.

[0003] Patent publication number CN212191820U relates to a fork welding cold treatment device, comprising: a chuck including multiple radially movable jaws; a cooling mechanism including a cooling mandrel located between the multiple jaws, the multiple jaws clamping and fixing the cooling mandrel; the cooling mandrel having an internal cavity, the cooling mandrel including a main body and a connecting portion protruding from the upper end of the main body, the lower end of the main body having a water inlet and a water outlet, and the cavity communicating with the outside through the water inlet and water outlet. This fork robotic welding device uses a cooling mechanism to cool the fork during the welding process, allowing the fork to maintain a low temperature during welding.

[0004] In the aforementioned patent, the cooling mechanism is used to cool the fork during the welding process, so that the fork can maintain a low temperature during the welding process. However, the welding slag produced during welding may splatter out, which may cause injury to the operator. At the same time, there may be errors in the alignment of the fork on the workbench during the welding process, which may cause welding problems and affect the normal welding effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a welding device for processing bicycle parts, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding device for processing bicycle parts, comprising: a housing; a sliding door slidably mounted on the inner wall of the housing; welding equipment disposed on the inner wall of the housing; a lifting platform disposed at the bottom of the inner wall of the housing; a rotary table fixedly mounted on the output end of the lifting platform, the lifting platform being used to drive the rotary table to rise and fall; a linear motor disposed on the top of the rotary table; a fixed frame fixedly mounted on the output end of the linear motor; a connecting frame fixedly mounted on the top of the rotary table; a ring fixedly mounted on the surface of the rotary table; an L-shaped sliding plate slidably mounted on the bottom of the inner wall of the housing; an L-shaped frame fixedly mounted on the surface of the L-shaped sliding plate; a fixed block fixedly mounted on the surface of the L-shaped frame; a hinge rod rotatably mounted on the surface of the fixed block; the end of the hinge rod away from the fixed block rotatably mounted on the surface of the sliding door; the upward movement of the L-shaped frame causes the fixed block to move upward; the upward movement of the fixed block causes the hinge rod to rotate upward; the upward rotation of the hinge rod pushes the sliding door towards the center of the housing.

[0007] According to the above technical solution, a first spring is provided between the chassis and the L-shaped slide plate, and the L-shaped slide plate is reset by the elastic force of the first spring. A first torsion spring is provided between the fixed block and the hinge rod, and the hinge rod is reset by the elastic force of the first torsion spring. A second spring is provided between the sliding door and the chassis, and the sliding door is reset by the elastic force of the second spring.

[0008] According to the above technical solution, the chassis is equipped with an auxiliary welding calibration device and a fixing device. The calibration device includes an annular frame, a slide rod, a U-shaped pulley frame, a trapezoidal slide plate, and a fixed base. The upward movement of the rotating table drives the connecting frame to move upward, which in turn drives the trapezoidal slide plate to move upward. The trapezoidal slide plate is squeezed by the U-shaped pulley frame as it moves upward. The annular frame is fixedly installed at the bottom of the inner wall of the chassis. The slide rod is slidably installed on the inner wall of the annular frame and slides through the surface of the rotating table. The U-shaped pulley frame is fixedly installed at the top of the slide rod. The trapezoidal slide plate is slidably installed on the surface of the connecting frame. A push plate is fixedly installed on the surface of the trapezoidal slide plate. The fixed base is fixedly installed on the surface of the connecting frame, and a rotating plate is rotatably installed on the inner wall of the fixed base.

[0009] According to the above technical solution, an L-shaped plate is fixedly installed on the surface of the trapezoidal slide plate, a hinge plate is rotatably installed on the inner wall of the L-shaped plate, a support plate is slidably installed on the inner wall of the connecting frame, a connecting seat is fixedly installed on the surface of the support plate, and a hinge plate is rotatably installed on the inner wall of the connecting seat. When the hinge plate rotates upward, it will cause the connecting seat to move upward, and when the connecting seat moves upward, it will cause the support plate to move upward.

[0010] According to the above technical solution, a No. 3 spring is provided between the trapezoidal slide plate and the connecting frame, and the trapezoidal slide plate is reset by the elastic force of the No. 3 spring. A No. 2 torsion spring is provided between the fixed seat and the rotating plate, and the rotating plate is reset by the elastic force of the No. 2 torsion spring. A No. 4 spring is provided between the connecting frame and the support plate, and the support plate is reset by the elastic force of the No. 4 spring.

[0011] According to the above technical solution, the fixing device includes a long plate, a fixed plate, and an arc-shaped plate. The long plate moves upward by the support plate, which in turn moves the fixed plate upward, which in turn moves the arc-shaped plate upward. The long plate is fixedly installed on the surface of the support plate, the fixed plate is fixedly installed on the surface of the long plate, and the arc-shaped plate is fixedly installed on the surface of the fixed plate.

[0012] According to the above technical solution, a square plate is fixedly installed on the top of the arc-shaped plate, a sliding frame is slidably installed on the surface of the fixed frame, a connecting rod is fixedly installed on the top of the sliding frame, a pushing plate is slidably installed on the inner wall of the fixed frame, and a trapezoidal plate is fixedly installed on the surface of the pushing plate. When the connecting rod moves upward, it will push the trapezoidal plate to move closer to the fixed frame, and the movement of the trapezoidal plate to move closer to the fixed frame will drive the pushing plate to move closer to the fixed frame.

[0013] According to the above technical solution, a No. 5 spring is provided between the fixed frame and the sliding frame, and the fixed frame is reset by the elastic force of the No. 5 spring itself. A No. 6 spring is provided between the fixed frame and the push plate, and the push plate is reset by the elastic force of the No. 6 spring itself.

[0014] This invention provides a welding apparatus for processing bicycle parts. It has the following advantages: (1) In this invention, the two ends of the bicycle front fork are respectively inserted into the fixed frame and the connecting frame. Then, the linear motor is started, and the linear motor will drive the fixed frame to move closer to the connecting frame. By aligning the two ends to be welded, no manual fixing is required, which improves the welding efficiency. At the same time, the lifting platform is started to rise, and the rising of the lifting platform will drive the rotating platform to rise. The welding equipment is used to weld the bicycle front fork. At the same time, the rotating platform will rotate to adjust the welding position, which improves the welding efficiency.

[0015] (2) The invention can ensure that the welding process will not be affected by the instability of the table by raising the rotating table, thereby improving the stability of the welding. The upward movement of the fixed block will squeeze the hinge rod to rotate upward, and the upward rotation of the hinge rod will push the sliding door to move towards the middle of the chassis. The chassis will be closed by the opposite movement of the sliding door, preventing the user from opening the sliding door during the welding process, which would cause the welding slag generated during welding to splatter and vent, affecting the working environment.

[0016] (3) In this invention, the push plate moves towards the fixed frame, which pushes the rotating plate towards the fork. The rotation of the rotating plate calibrates the position of the fork, preventing misalignment between the welded parts, which would cause deviations during welding and affect the welding effect. At the same time, the upward rotation of the hinge plate will drive the connecting seat to move upward, which will drive the support plate to move upward. The upward movement of the support plate will support the bottom of the fork, ensuring stability during welding and preventing the fork from bending downward, which would affect the welding effect.

[0017] (4) In this invention, the welding slag generated during welding when the arc plate rises falls into the interior of the arc plate, preventing the support from falling onto the rotating platform and splashing out when the rotating platform rotates, thus obstructing the subsequent rotation of the rotating platform. At the same time, the upward movement of the connecting rod will push the trapezoidal plate to move closer to the fixed frame. The movement of the trapezoidal plate to move closer to the fixed frame will drive the push plate to move closer to the fixed frame. The movement of the push plate to move closer to the fixed frame will push the welded parts to align, preventing gaps between the welded parts and affecting the stability of the welding.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 7 One embodiment of the present invention is a welding device for processing bicycle parts, comprising: a housing 1; a sliding door 2, the sliding door 2 being slidably installed on the inner wall of the housing 1; a welding device 3, the welding device 3 being disposed on the inner wall of the housing 1; a lifting platform 4, the lifting platform 4 being disposed at the bottom of the inner wall of the housing 1; a rotary table 5, the rotary table 5 being fixedly installed at the output end of the lifting platform 4, the lifting platform 4 being used to drive the rotary table 5 to rise and fall; a linear motor 6, the linear motor 6 being disposed on the top of the rotary table 5; a fixing bracket 7 being fixedly installed at the output end of the linear motor 6, and a fixing bracket 7 being fixedly installed on the top of the rotary table 5. The machine has a connecting frame 8, a rotating table 5 with a ring 9 fixedly installed on its surface, an L-shaped slide plate 10 slidingly installed on the bottom of the inner wall of the machine housing 1, an L-shaped frame 11 fixedly installed on the surface of the L-shaped slide plate 10, a fixing block 12 fixedly installed on the surface of the L-shaped frame 11, a hinge rod 13 rotatably installed on the surface of the fixing block 12, and the end of the hinge rod 13 away from the fixing block 12 rotatably installed on the surface of the sliding door 2. The machine housing 1 is closed by the opposite movement of the sliding door 2, preventing the user from opening the sliding door 2 during the welding process, which would cause the welding slag generated during welding to splatter and vent gas, affecting the working environment.

[0022] A first spring is installed between the chassis 1 and the L-shaped slide plate 10. The L-shaped slide plate 10 is reset by the elastic force of the first spring. A first torsion spring is installed between the fixing block 12 and the hinge rod 13. The hinge rod 13 is reset by the elastic force of the first torsion spring. A second spring is installed between the sliding door 2 and the chassis 1. The sliding door 2 is reset by the elastic force of the second spring.

[0023] In this embodiment, the bicycle front fork is engaged with the two ends of the fixing frame 7 and the connecting frame 8 respectively. Then, the linear motor 6 is activated, causing the fixing frame 7 to move closer to the connecting frame 8. By aligning the two ends to be welded, manual fixing is not required, improving welding efficiency. Simultaneously, the lifting platform 4 is activated, which in turn raises the rotating platform 5. This, in conjunction with the welding equipment 3, allows for welding of the bicycle front fork. The rotating platform 5 also rotates to adjust the welding position, further improving welding efficiency. Furthermore, the rising of the rotating platform 5 ensures that instability on the platform does not cause welding problems during the process. Necessary movement improves welding stability. When the rotary table 5 rises, it drives the ring 9 to rise. The rise of the ring 9 pushes the L-shaped slide plate 10 to move upward. The upward movement of the L-shaped slide plate 10 drives the L-shaped frame 11 to move upward. The upward movement of the L-shaped frame 11 drives the fixed block 12 to move upward. The upward movement of the fixed block 12 squeezes the hinge rod 13 to rotate upward. The upward rotation of the hinge rod 13 pushes the sliding door 2 to move towards the middle of the chassis 1. The reverse movement of the sliding door 2 closes the chassis 1, preventing the user from opening the sliding door 2 during the welding process, which would cause the welding slag generated during welding to splatter and vent, affecting the working environment.

[0024] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, the chassis 1 is provided with a calibration device and a fixing device for auxiliary welding. The calibration device includes an annular frame 141, a slide rod 142, a U-shaped pulley frame 143, a trapezoidal slide plate 144, and a fixing seat 146. The annular frame 141 is fixedly installed at the bottom of the inner wall of the chassis 1. The slide rod 142 is slidably installed on the inner wall of the annular frame 141 and slides through the surface of the rotary table 5. The U-shaped pulley frame 143 is fixedly installed at the top of the slide rod 142. The trapezoidal slide plate 144 is slidably installed on the surface of the connecting frame 8. A push plate 145 is fixedly installed on the surface of the trapezoidal slide plate 144. The fixing seat 146 is fixedly installed on the surface of the connecting frame 8. A rotating plate 147 is rotatably installed on the inner wall of the fixing seat 146. The position of the fork is calibrated by rotating the rotating plate 147 to prevent misalignment between the welded parts, which would cause deviations during welding and affect the welding effect.

[0025] An L-shaped plate 148 is fixedly installed on the surface of the trapezoidal slide plate 144. A hinge plate 149 is rotatably installed on the inner wall of the L-shaped plate 148. A support plate 1410 is slidably installed on the inner wall of the connecting frame 8. A connecting seat 1411 is fixedly installed on the surface of the support plate 1410. The hinge plate 149 is rotatably installed on the inner wall of the connecting seat 1411. When the support plate 1410 moves upward, it will support the bottom of the fork, ensuring stability during welding and preventing the fork from bending downward, which would affect the welding effect.

[0026] A No. 3 spring is installed between the trapezoidal slide plate 144 and the connecting frame 8. The No. 3 spring's own elastic force drives the trapezoidal slide plate 144 to reset. A No. 2 torsion spring is installed between the fixed base 146 and the rotating plate 147. The No. 2 torsion spring's own elastic force drives the rotating plate 147 to reset. A No. 4 spring is installed between the connecting frame 8 and the support plate 1410. The No. 4 spring's own elastic force drives the support plate 1410 to reset.

[0027] In this embodiment, during operation: the upward movement of the rotary table 5 causes the connecting frame 8 to move upward, which in turn causes the trapezoidal slide plate 144 to move upward. The trapezoidal slide plate 144, moving upward, is compressed by the U-shaped pulley frame 143, which pushes it towards the fixed frame 7. This movement of the trapezoidal slide plate 144 towards the fixed frame 7 causes the push plate 145 to move towards the fixed frame 7. The push plate 145's movement towards the fixed frame 7 then pushes the rotating plate 147 to rotate towards the front fork. The rotation of the rotating plate 147 adjusts the position of the front fork. Calibration is performed to prevent misalignment between welded parts, which could lead to deviations during welding and affect the welding effect. At the same time, the movement of the trapezoidal slide plate 144 towards the fixed frame 7 will cause the L-shaped plate 148 to move towards the fixed frame 7. The movement of the L-shaped plate 148 towards the fixed frame 7 will push the hinge plate 149 to rotate upward. The upward rotation of the hinge plate 149 will cause the connecting seat 1411 to move upward. The upward movement of the connecting seat 1411 will cause the support plate 1410 to move upward. The upward movement of the support plate 1410 will support the bottom of the fork, ensuring stability during welding and preventing the fork from bending downward, which would affect the welding effect.

[0028] The fixing device includes a long plate 151, a fixing plate 152, and an arc plate 153. The long plate 151 is fixedly installed on the surface of the support plate 1410, the fixing plate 152 is fixedly installed on the surface of the long plate 151, and the arc plate 153 is fixedly installed on the surface of the fixing plate 152. When the arc plate 153 rises, the welding slag generated during welding falls into the interior of the arc plate 153, preventing the support from falling onto the rotary table 5. Subsequently, when the rotary table 5 rotates, the slag is splashed out, thus obstructing the subsequent rotation of the rotary table 5.

[0029] A square plate 154 is fixedly installed on the top of the arc plate 153. A sliding frame 155 is slidably installed on the surface of the fixing frame 7. A connecting rod 156 is fixedly installed on the top of the sliding frame 155. A push plate 157 is slidably installed on the inner wall of the fixing frame 7. A trapezoidal plate 158 is fixedly installed on the surface of the push plate 157. The push plate 157 moves towards the fixing frame 7 to push the welded parts to align, preventing gaps between the welded parts and affecting the stability of the welding.

[0030] A No. 5 spring is installed between the fixed frame 7 and the sliding frame 155. The fixed frame 7 is reset by the elastic force of the No. 5 spring. A No. 6 spring is installed between the fixed frame 7 and the push plate 157. The push plate 157 is reset by the elastic force of the No. 6 spring.

[0031] The upward movement of the support plate 1410 causes the long plate 151 to move upward, which in turn causes the fixed plate 152 to move upward. The upward movement of the fixed plate 152 causes the arc plate 153 to move upward. As the arc plate 153 rises, the welding slag generated during welding falls into the arc plate 153, preventing the support from falling onto the rotary table 5. Subsequently, when the rotary table 5 rotates, the slag is splashed out, obstructing the subsequent rotation of the rotary table 5. At the same time, the upward movement of the arc plate 153 causes the square plate 154 to move upward, which in turn causes the sliding frame 155 to move upward. The upward movement of the sliding frame 155 causes the connecting rod 156 to move upward, which pushes the trapezoidal plate 158 towards the fixed frame 7. The movement of the trapezoidal plate 158 towards the fixed frame 7 causes the push plate 157 to move towards the fixed frame 7. The movement of the push plate 157 towards the fixed frame 7 promotes the alignment between the welded parts, preventing gaps between the welded parts and affecting the stability of the welding.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
