Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle pedal processing, and particularly relates to a motorcycle pedal processing technology. Background Art

[0002] Motorcycle pedals are an important part of motorcycles. Generally, common pedals on motorcycle bodies include shift pedals, brake pedals, rear footrests, etc. There are obvious differences between the materials of ordinary motorcycle pedals and high-end motorcycle pedals. Generally, the materials of ordinary motorcycle pedals are mostly ordinary steel or engineering plastics, while high-end motorcycle pedals often use high-quality metal materials such as aluminum alloy and stainless steel.

[0003] Currently, the main structure of existing high-end motorcycle pedals is generally die-cast, and the components on both sides and in the middle are reinforced by subsequent welding. During the welding process of the main structure of the pedal and the components on both sides and in the middle, manual support for welding is mostly relied on. The operator is too close to the welding area, and most of the pedal welding equipment operates naked during work. This leads to the direct emission of fumes and welding dust generated during the welding process, which will affect the physical safety of the operator. At the same time, some existing welding equipment has poor automation. For example, when some enterprises weld motorcycle shift pedals, they still use the method of the operator holding a welding torch. This is not only inconvenient to use, but also has poor protection effect and is prone to causing injuries to the operator. Moreover, the method of manual support for welding is not only slow but also prone to fatigue, and cannot meet the requirements of batch and large-scale production. To address the above-mentioned problems, it is necessary to optimize and improve the deficiencies existing in the welding of existing high-end motorcycle pedals. Therefore, this application provides a motorcycle pedal processing technology to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a motorcycle pedal processing technology to solve the problems that some of the existing motorcycle pedal welding equipment has poor automation, resulting in low welding efficiency and inability to meet the requirements of batch and large-scale production. At the same time, most of the existing welding equipment operates naked, and the fumes and welding dust during welding are directly emitted, affecting the working environment and the physical health of the operator.

The lower ends of the four screw rods penetrate through the inside of the inner moving module and extend downward to the inside of the rotating disc.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In the above solution, through the erected frames arranged on the left and right sides of the outer end of the workbench, a vertical hoisting structure dedicated to the workbench is formed in cooperation with the winding crossbeam. When welding is required, as long as the wire rope between the winding crossbeam and the protection module is controlled to retract and extend, the protection module can slide down along the guiding chutes opened on the opposite sides of the left and right erected frames and fit with the upper surface of the workbench to form a sealed structure, so that the fumes and welding dust generated by the operation of the welding manipulator will not spread out. Moreover, the fumes and welding dust are extracted by the exhaust fan arranged inside the protection module, sent into the annular filter pipe along the conveying pipe for preliminary filtration, and then discharged into the adsorption box by the discharge fan for activated carbon adsorption, and then discharged through the pipeline communicated with the top of the adsorption box. Compared with traditional exposed welding, the whole welding process is carried out in a relatively sealed environment and is equipped with special air extraction, filtration and adsorption structures, so that the fumes and welding dust generated by the whole welding can be processed in time and will not be emitted to affect the health of operators and the working environment.

[0025] Through the installed module, the jigs are first arranged symmetrically at the upper end of the installation ring block. When welding the motorcycle pedal is required, the pedal main component is placed on the upper end of the feeding table, and then the feeding table is inserted into the slot opened at the lower end of the feeding rack. The main component is grabbed by the loading manipulator and cooperates with the forward and backward expansion and contraction of the telescopic module to place the main component into the jig to achieve automatic feeding. Then, the rotating disk is driven by the servo motor inside the workbench to work, so that the inner moving module meshes with the rotating module, thereby driving the installation ring block fixed to the rotating module to rotate. When the jig placing the main component rotates to the rear side of the workbench, the operator manually tightens the jig to fix the pedal main component and paste and place the components on both sides and in the middle. After all the main components and the components on both sides and in the middle are placed and fixed in the symmetrically arranged jigs, the protection module is closed with the workbench, and the welding manipulator installed inside the protection module starts welding work. Compared with the traditional welding that requires manual support during welding, it will be safer. At the same time, the automatic feeding, the installation ring block and the symmetrically arranged jigs can fix multiple groups of pedal components, cooperate with the welding manipulator to achieve batch welding, optimize the automation level of the welding work and improve the efficiency of the welding work.

[0026] Through the hierarchical installation structure of the internal structures of the inner moving module and the rotating module, when the external meshing teeth or internal meshing teeth are damaged, the external meshing teeth or internal meshing teeth can be directly disassembled from the inner moving module and the rotating module to achieve rapid separation, which is convenient for subsequent maintenance work. Compared with the inner moving module or rotating module with an integrated structure, the maintenance cost will also be more economical. Brief Description of the Drawings

[0046] As Figures 1 to 10 shown, an embodiment of the present invention provides a processing technology for a motorcycle pedal, including the following steps:

[0047] S1. Raw material preparation: Select suitable materials according to the performance of the pedal and cut the materials according to the required size specifications;

[0048] S2. Forming processing: According to the simplicity or complexity of the pedal structure, use die stamping or cutting processing to process the pedal;

[0049] S3. Surface treatment: Perform manual or mechanical deburring, heat treatment, and surface protection treatment on the formed pedal;

[0050] S4. Assembly and welding: According to the parts of the pedal, use either a pasting assembly method or a welding device to weld the components;

[0051] S5. Quality inspection: Check the dimensions and surface of the pedal for defects and conduct performance tests;

[0052] S6. Packaging and Factory Delivery: Clean the qualified pedals, wrap them with plastic tape or bubble wrap, and then pack them in boxes according to specifications;

[0053] The welding device includes a workbench 1. On the left and right sides of the outer end of the workbench 1, there are vertically installed frames 2 attached. Inside the top of the vertically installed frames 2, there is a winding crossbeam 3. Below the winding crossbeam 3, there is a protective module 4 suspended. Below the protective module 4, there is an installation module 5. Inside the lower end of the protective module 4, there is a welding manipulator 6. On the upper end of the installation module 5, there is a fixture 7. In the middle below the installation module 5, there is an inner moving module 8. On the outer end of the inner moving module 8, there is a rotating module 9. Inside the upper end of the inner moving module 8, there is a reinforcement plate 10. Inside the lower end of the inner moving module 8, there is a rotating disk 11. In front of the workbench 1, there is a feeding rack 12. On the front side of the upper end of the feeding rack 12, there is a telescopic module 13. In the middle of the lower end of the telescopic module 13, there is a loading manipulator 14. Below the inner side of the feeding rack 12, there is a feeding table 15.

[0054] The overall shapes of the workbench 1 and the protection module 4 are both octagonal. After they are fitted to each other, a complete sealed structure is formed. The inner sides of the lower ends of the vertical frames 2 are respectively fitted to the left and right sides of the octagonal surface on the outside of the workbench 1. At the same time, the left and right fixing irons arranged on the front and rear sides below the outer end of the workbench 1 are spliced with the L-shaped angle irons 203 installed on the outer sides of the lower ends of the vertical frames 2, and both the fixing irons and the L-shaped angle irons 203 are fixed to the ground by anchor bolts. Lifting blocks are provided on the left and right sides at the upper ends of the winding cross beam 3 and the protection module 4. The winding cross beam 3 and the protection module 4 are connected together by steel wires. Among them, the winding cross beam 3 is a welded integral structure composed of a steel frame and a shell, and the contact ends with the inner sides of the upper ends of the two groups of vertical frames 2 are reinforced by bolts. Wire holes are opened on the left and right sides at the lower end of the winding cross beam 3, facilitating the steel wire to pass through when tightening to lift the protection module 4. At the same time, since a winding motor and a winding roller are installed inside the winding cross beam 3, and the transmission end of the winding motor and the winding roller are integrally installed, which is a relatively typical winding device in the existing technology, therefore, the internal devices thereof will not be described in detail in this article. The left and right sides of the outer end of the protection module 4 extend to the inner sides of the opposite ends of the vertical frames 2. The installation module 5 is a disc-shaped structure. Annular holes are opened on the outer side at the lower end of the disc-shaped structure for installing the support columns 503. The support columns 503 are located in the middle area between the installation module 5 and the rotation module 9, playing a supporting role, making the installation module 5 and the lower structure present a layered structure, and the height of the layered structure is adjustable. Four welding manipulators 6 are symmetrically installed, and are installed in a cross shape at the outer corners of the lower end of the splicing disc 405. All four welding manipulators 6 are electrically connected to the main controller installed in the middle of the lower end of the splicing disc 405. By starting from three aspects of hardware connection, control logic, and synchronization mechanism, the four welding manipulators 6 are highly consistent in instruction reception, action execution, and status feedback, achieving the effect of synchronous control. This technology of mechanical synchronous work belongs to the existing well-known technology in the automation field, so it will not be described in detail in this article. The jigs 7 are arranged in an octagonal symmetry distribution on the upper end of the installation module 5, and the lower ends of the jigs 7 extend into the interior of the installation module 5. The jigs 7 need to be tightened and reinforced manually by turning the knob. The inner moving module 8 and the rotation module 9 are sleeved with each other, and their contact ends are meshed. Four screw rods are symmetrically distributed on the outer side of the upper end of the reinforcement disc 10. The lower ends of the four screw rods penetrate through the interior of the inner moving module 8 and extend downward to the interior below the outer end of the rotating disc 11. The rectangular groove opened on the inner side of the rotating disc 11 is of the same size as the rectangular transmission end of the upper end of the servo motor 103. The material feeding rack 12 is in a vertical inverted U-shaped structure, and the interior of its top is a hollow structure. The front structures of the telescopic module 13 are all installed in the hollow structure opened at the top of the material feeding rack 12. The contact end of the material loading manipulator 14 and the telescopic module 13 is reinforced by bolts. The material feeding table 15 is slidably embedded and installed in the inner side slot at the lower end of the material feeding rack 12, and sliding beads can be installed at the bottom of the material feeding table 15.

[0055] During operation, through the installed mounting module 5, the jigs 7 are first symmetrically arranged at the upper end of the mounting ring block 501. When motorcycle pedal welding work needs to be carried out, the pedal main body component is placed on the upper end of the feeding table 15. Then, the feeding table 15 is inserted into the slot opened at the lower end of the feeding rack 12. The feeding robot 14 grabs the main body component and cooperates with the forward and backward expansion of the expansion module 13 to place the main body component into the jig 7 to achieve automatic feeding. Then, the servo motor 103 inside the workbench 1 drives the rotating disk 11 to work, causing the inner moving module 8 to mesh with the rotating module 9, thereby driving the mounting ring block 501 fixed to the rotating module 9 to rotate. When the jig 7 placing the main body component rotates to the rear side of the workbench 1, the operator manually operates the jig 7 to tighten and fix the pedal main body component and paste and place the components on both sides and in the middle. After all the main components and the components on both sides and in the middle are placed and fixed in the symmetrically arranged jigs 7, the protection module 4 closes with the workbench 1, and the welding robot 6 installed inside the protection module 4 starts welding work. Compared with the traditional welding that requires manual support during welding, it is safer. At the same time, the automatic feeding, the mounting ring block 501, and the symmetrically arranged jigs 7 can fix multiple groups of pedal components, and cooperate with the welding robot 6 to achieve batch welding, optimizing the automation level of the welding work and improving the efficiency of the welding work.

[0056] During operation, through the installed vertical frames 2, they are installed on the left and right sides of the outer end of the workbench 1, and cooperate with the winding cross beam 3 to form a vertical hoisting structure dedicated to the workbench 1. When welding is required, as long as the winding cross beam 3 controls the winding and unwinding of the steel wire rope between it and the protection module 4, the protection module 4 can slide down along the guiding chute 205 opened on the opposite side of the left and right vertical frames 2 to fit with the upper surface of the workbench 1 to form a sealed structure, so that the fumes and welding dust generated by the work of the welding robot 6 will not spread. Moreover, the exhaust fan 406 installed inside the protection module 4 extracts the fumes and welding dust, sends them into the annular filter pipe 408 through the conveying pipe 407 for preliminary filtration, and then the exhaust fan 409 discharges them into the adsorption box 402 for activated carbon adsorption, and then discharges them through the pipeline connected to the top of the adsorption box 402. Compared with traditional exposed welding, the entire welding process is carried out in a relatively sealed environment, and there is a dedicated exhaust, filtration, and adsorption structure, so that the fumes and welding dust generated during the entire welding can be processed in time and will not be emitted to affect the health of the operator and the working environment.

[0057] As Figures 1 to 2As shown in the figure, in this embodiment, the workbench 1 includes a pedestal 101, an embedding groove 102, a servo motor 103, a ball groove 104, balls 105 and a sealing plate 106. An embedding groove 102 is formed in the inner side of the upper end of the pedestal 101. A servo motor 103 is provided in the middle of the inner side of the embedding groove 102. A ball groove 104 is formed in the outer side of the embedding groove 102. Balls 105 are embedded and installed in the ball groove 104. A sealing plate 106 is provided in the middle of the front end of the pedestal 101.

[0058] A circular embedding groove 102 is formed in the inner side of the upper end of the pedestal 101. A servo motor 103 is installed below the middle of the inner side of the embedding groove 102. The transmission end of the servo motor 103 has a rectangular structure which extends upward into the interior of the rotating disk 11. An annular ball groove 104 is formed in the outer side of the embedding groove 102. The ball groove 104 and the embedding groove 102 are separated by the inner wall of the upper end of the pedestal 101. Twelve symmetrically distributed balls 105 are embedded and installed in the inner side of the upper end of the ball groove 104. The lower ends of the balls 105 are in contact with the ball groove 104 while the upper ends of the balls 105 are in contact with the lower end of the outer rotating block 901. The sealing plate 106 is fixed to the pedestal 101 by screws and is used to open the inner space of the pedestal 101 later.

[0059] Through the provided pedestal 101, due to its eight contact surfaces at the outer end, only two symmetric contact surfaces are needed when it is fitted and installed with the vertical frame 2, and there are still six contact surface working areas left, which is convenient for subsequent work. At the same time, through the design of the embedding groove 102, the rotating disk 11 can be installed inside to support the inner moving module 8 while keeping the inner moving module 8 in a suspended state so that it will not rub against the pedestal 101 itself during rotation. Secondly, due to the cooperation of the ball groove 104 and the balls 105, the rotating module 9 will not directly contact the pedestal 101 either, which not only improves the service life of the inner moving module 8 and the rotating module 9 but also reduces the difficulty of their rotation.

[0060] As Figures 1 to 3 As shown in the figure, in this embodiment, the vertical frame 2 includes a left frame 201, a right frame 202, L-shaped angle irons 203, fixing pins 204 and guide chutes 205. The left frame 201 and the right frame 202 are symmetrically distributed with respect to each other. L-shaped angle irons 203 are provided on the left and right sides of the lower ends of the left frame 201 and the right frame 202. Fixing pins 204 are provided at the contact ends of the L-shaped angle irons 203 with the left frame 201 and the right frame 202. Guide chutes 205 are formed on the left and right sides of the opposite surfaces of the left frame 201 and the right frame 202.

[0061] The overall size and shape of the left frame 201 and the right frame 202 are exactly the same, and the installation angles of the two are symmetrical. Placement notches are provided on the relative inner sides of the upper ends of the left frame 201 and the right frame 202. The horizontal diameter of the placement notch is in line with the diameters of the left and right ends of the winding cross beam 3. The lower part of the contact end of the placement notch and the winding cross beam 3 is reinforced by bolts. Moreover, two guiding sliding grooves 205 are provided on the left and right sides of the relative surfaces of the two. The width diameter inside the guiding sliding groove 205 is in line with the width diameter of the guiding strip 403 provided at the outer end of the table cover 401. At the same time, installation notches of different heights are longitudinally provided inside the left frame 201 and the right frame 202, facilitating the subsequent installation of equipment and the placement of some tools. Four L-shaped angle irons 203 are symmetrically distributed, and the erected ends of the L-shaped angle irons 203 are in contact with the left frame 201 and the right frame 202 and are reinforced together by fixing pins 204. The bottom end of the L-shaped angle iron 203 is trapezoidal, and the angle at the bottom end of the trapezoid is in line with the distribution angle of the outer wall of the workbench 1, facilitating the subsequent assembly work.

[0062] During operation, through the provided left frame 201 and right frame 202, the two are fitted and installed on the left and right sides of the outer end of the workbench 1 and fixed to the ground by the L-shaped angle irons 203, cooperating with the winding cross beam 3 to form a vertical simple hoisting structure dedicated to the octagonal workbench 1. At the same time, through the design of the guiding sliding grooves 205, the protection module 4 is embedded and installed in the middle area opposite to the left frame 201 and the right frame 202, facilitating the subsequent hoisting of the protection module 4 for lifting work, so as to achieve closing and separation from the workbench 1, enabling the subsequent welding work to be carried out in a relatively sealed environment and improving the safety of the welding work. When subsequent disassembly is required, only the L-shaped angle irons 203 need to be separated from the ground, and the lifting blocks on the left and right sides of the upper end of the winding cross beam 3 are hoisted, and the entire upright frame 2 and the winding cross beam 3 can be taken away from above the workbench 1.

[0063] As Figure 4 and Figure 5 shown, in this embodiment, the protection module 4 includes a table cover 401, an adsorption box 402, a guiding strip 403, a main fan disk 404, a splicing disk 405, an exhaust fan 406, a conveying pipe 407, an annular filter pipe 408, and an exhaust fan 409. An adsorption box 402 is provided in the middle of the upper end of the table cover 401, guiding strips 403 are provided on the left and right sides of the outer end of the table cover 401, a main fan disk 404 is provided above the inside of the table cover 401, a splicing disk 405 is provided below the main fan disk 404, an exhaust fan 406 is provided inside the upper end of the splicing disk 405, the upper end of the exhaust fan 406 is communicated with a conveying pipe 407, the upper end of the conveying pipe 407 is communicated with an annular filter pipe 408, and an exhaust fan 409 is provided inside the upper end of the main fan disk 404.

[0064] The contact end of the table cover 401 and the adsorption box 402 is installed in a threaded manner. There are four guide bars 403 symmetrically distributed, and the four guide bars 403 and the table cover 401 are of an integral structure. The main fan disk 404 and the splicing disk 405 are both reinforced inside the lower end of the table cover 401 by long screws. Moreover, the overall diameters of the main fan disk 404 and the splicing disk 405 are adapted to the inner cavity diameter of the lower end of the table cover 401. The splicing disk 405 is composed of an inner and an outer part. The inner part has an annular inner cross-support structure, and the outer part has an annular outer disk structure. The two are fixedly integrated by seal welding. Four welding manipulators 6 are installed in a cross shape on the four sides at the lower end of the annular outer disk structure. A main controller is installed in the middle at the lower end of the annular inner cross-support structure. Four fan holes are symmetrically opened on the outer side at the lower end of the annular inner cross-support structure. An air extraction fan 406 is installed inside the fan holes. At the same time, annular wiring grooves are opened at both the upper and lower ends of the annular inner cross-support structure. The annular wiring grooves at the upper and lower ends are connected to each other through threading holes, facilitating the connection of the upper and lower lines, and the annular wiring grooves are also used to connect the four fan holes. The delivery pipe 407 is installed in a threaded manner with the air extraction fan 406. The upper end of the delivery pipe 407 is interconnected with the annular filter pipe 408. A filter element is installed inside the annular filter pipe 408. The annular filter pipe 408 is interconnected with the inner cavity of the main fan disk 404. Secondly, the main fan disk 404 and the adsorption box 402 are interconnected. A hollow filter screen is provided at their contact end. The inside of the adsorption box 402 is filled with activated carbon.

[0065] During operation, through the set table cover 401, it can be fitted with the workbench 1 to form a sealed structure. After that, when the welding manipulator 6 starts working, the fumes and welding dust generated by welding are extracted by the air extraction fan 406, sent into the annular filter pipe 408 along the delivery pipe 407 for preliminary filtration, and then discharged into the adsorption box 402 by the exhaust fan 409 for activated carbon adsorption, and then discharged through the pipeline connected to the top of the adsorption box 402. Compared with traditional exposed welding, the entire welding process is carried out in a relatively sealed environment, and is equipped with special air extraction, filtration and adsorption structures, so that the fumes and welding dust generated during the entire welding can be processed in time and will not be emitted, affecting the physical health of the operator and the working environment.

[0066] As Figures 1 to 6 shown, in this embodiment, the installation module 5 includes an installation ring block 501, insertion holes 502, support columns 503, heightening blocks 504 and anti-friction bearings 505. Insertion holes 502 are symmetrically opened on the outer side of the upper end of the installation ring block 501. Support columns 503 are installed in a threaded manner on the outer side of the lower end of the installation ring block 501. Heightening blocks 504 are sleeved on the outer ends of the support columns 503. An anti-friction bearing 505 is provided inside the middle of the upper end of the installation ring block 501.

[0067] The mounting ring block 501 is an integrally formed structure, and the middle part of the mounting ring block 501 is a hollow structure. The diameter of the hollow structure is adapted to the overall diameter of the anti-wear bearing 505. At the same time, screw holes are opened on the outer side of the lower end of the mounting ring block 501. Eight groups of jacks 502 are arranged in a parallel symmetric array on the outer side of the upper end of the mounting ring block 501. The jacks 502 are installed in a plug-in manner with the fixture 7. The upper end of the support column 503 is threadedly installed with the thread opened at the lower end of the mounting ring block 501. The heightening block 504 is sleeved on the outer side of the upper end of the support column 503. The height of the heightening block 504 is defined. By adding or reducing the heightening block 504, the height between the mounting ring block 501 and the rotating module 9 can be adjusted. The anti-wear bearing 505 is installed in an embedded manner with the mounting ring block 501.

[0068] During operation, through the provided support column 503 and heightening block 504, when the fixture 7 clamps motorcycle pedals of different sizes for welding, the height between the mounting ring block 501 and the rotating module 9 can be adjusted, so as to adjust the size of the internal welding cavity area after the protection module 4 and the workbench 1 are closed. At the same time, through the eight groups of jacks 502 arranged in an array, more fixtures 7 can also be arranged in an eight-group array, realizing the clamping and fixing work of eight groups of pedals. Cooperating with four welding manipulators 6 to weld two groups each, more motorcycle pedals can be welded at one time, realizing batch processing efficiency.

[0069] As Figure 7 and Figure 8 shown, in this embodiment, the inner moving module 8 includes an inner rotating block 801, an inner sleeve ring 802, meshing external teeth 803, and a positioning hole 804. An inner sleeve ring 802 is provided on the outer side of the inner rotating block 801. Meshing external teeth 803 are opened above the outer end of the inner sleeve ring 802. A positioning hole 804 is opened in the middle inner side of the upper end of the inner rotating block 801; the rotating module 9 includes an outer rotating block 901, a support screw hole 902, an outer sleeve ring 903, and meshing internal teeth 904. A support screw hole 902 is opened in a ring shape at the upper end of the outer rotating block 901. An outer sleeve ring 903 is provided inside the outer rotating block 901. Meshing internal teeth 904 are opened above the inner side of the outer sleeve ring 903.

[0070] The inner rotating block 801 and the inner sleeve ring 802 are sleeved with each other, and the outer rotating block 901 and the outer sleeve ring 903 are also sleeved with each other. Moreover, the inner rotating block 801 and the inner sleeve ring 802 and the outer rotating block 901 and the outer sleeve ring 903 are fastened together by bolts in pairs to form an integrated installation structure. The meshing external teeth 803 are only one-third of the height of the outer wall of the inner sleeve ring 802, and the meshing internal teeth 904 are only one-third of the height of the inner wall of the outer sleeve ring 903. The meshing external teeth 803 and the meshing internal teeth 904 are meshed with each other. Positioning holes 804 are formed through the interiors of the inner rotating block 801 and the inner sleeve ring 802, and the opening angles between the two are equal. The support screw holes 902 are annularly distributed at the upper end of the outer rotating block 901.

[0071] During operation, through the provided meshing external teeth 803 and meshing internal teeth 904, the power generated by the servo motor 103 driving the rotating disk 11 to rotate can be transmitted to the inner moving module 8 through the reinforcement disk 10. The inner moving module 8 and the rotating module 9 are meshed with each other through the meshing external teeth 803 and meshing internal teeth 904, so that the rotational force is transmitted from the inner moving module 8 to the rotating module 9, and then transmitted to the installation module 5 through the rotating module 9, realizing the continuity when the welding manipulator 6 welds the motorcycle pedal parts fixed on the fixture 7. Secondly, through the hierarchical installation structure of the internal structures of the inner moving module 8 and the rotating module 9, when the meshing external teeth 803 or the meshing internal teeth 904 are damaged, the meshing external teeth 803 or the meshing internal teeth 904 can be directly disassembled from the inner moving module 8 and the rotating module 9, realizing rapid separation, which is convenient for subsequent maintenance work. Compared with the integrated inner moving module 8 or rotating module 9, the maintenance cost will also be more saved.

[0072] As Figure 9 and Figure 10 shown, in this embodiment, the telescopic module 13 includes a hydraulic piston 131, a cross plate 132, pulleys 133, groove rods 134 and wheel grooves 135. A cross plate 132 is provided at the front end of the hydraulic piston 131. Pulleys 133 are provided on the left and right sides of the outer end of the cross plate 132. Groove rods 134 are provided on the upper and lower sides of the pulleys 133. Wheel grooves 135 are formed inside the groove rods 134.

[0073] The front end of the hydraulic piston 131 is directly sleeved and installed with the cross plate 132 and fixed by screws. Two rotating shafts are installed through the interior of the cross plate 132. The left and right ends of the two rotating shafts sequentially penetrate through the symmetrically distributed four pulleys 133. There are four symmetrically distributed groove rods 134, with two in each group. Wheel grooves 135 are formed inside the opposite ends of each group of groove rods 134. The groove rods 134 are reinforced with the top structure of the feeding rack 12 through long insertion rods. The size of the wheel grooves 135 is mutually adapted to the pulleys 133.

[0074] During operation, through the provided hydraulic piston 131, after the loading robot 14 completes grasping the pedal main body component and finishes two-fold folding, it can push the cross plate 132 to move back and forth, driving the front end of the loading robot 14 to also move forward into the working area in the middle of the workbench 1 and the protection module 4, and stop above the fixture 7. Then, the pedal main body component is placed down, and the hydraulic piston 131 retracts backward with the cross plate 132, realizing the reset work of the loading robot 14. The main function of the entire telescopic module 13's operation process is to move the loading robot 14 back and forth, enabling the loading robot 14 to perform the loading work with an ordinary double-fold loading robot 14. The core advantage of the double-fold loading robot 14 lies in its simple structure, low probability of failure, and ability to minimize the equipment cost as much as possible.

[0075] The working principle of the technical solution provided by the present invention is as follows: First, through the provided installation module 5, the clamps 7 are symmetrically arranged at the upper end of the installation ring block 501. When welding the motorcycle pedal, the pedal main component is placed on the upper end of the feeding table 15. Then, the feeding table 15 is inserted into the slot opened at the lower end of the feeding rack 12. The feeding robot 14 grabs the main component and cooperates with the forward and backward expansion of the expansion module 13 to place the main component into the clamp 7 to achieve automatic feeding. Then, the servo motor 103 inside the workbench 1 drives the rotating disk 11 to work, enabling the inner moving module 8 to engage with the rotating module 9, thereby driving the installation ring block 501 fixed to the rotating module 9 to rotate. When the clamp 7 placing the main component rotates to the rear side of the workbench 1, an operator manually operates the clamp 7 to tighten and fix the pedal main component and paste and place the components on both sides and in the middle. After all the main components and the components on both sides and in the middle are placed and fixed in the symmetrically arranged clamps 7, the protection module 4 closes with the workbench 1, and the welding robot 6 installed inside the protection module 4 starts the welding work. Compared with the traditional welding method that requires manual support during welding, it is safer. At the same time, the automatic feeding, the installation ring block 501, and the symmetrically arranged clamps 7 can fix multiple groups of pedal components, and cooperate with the welding robot 6 to achieve batch welding, optimizing the automation level of the welding work and improving the efficiency of the welding work. Secondly, through the provided vertical frame 2, it is installed on the left and right sides of the outer end of the workbench 1 and forms a vertical hoisting structure dedicated to the workbench 1 in cooperation with the winding cross beam 3. When welding is required, as long as the winding cross beam 3 controls the winding and unwinding of the steel wire rope between it and the protection module 4, the protection module 4 slides down along the guiding chute 205 opened on the opposite side of the left and right vertical frames 2 and fits with the upper surface of the workbench 1 to form a sealed structure, preventing the fumes and welding dust generated by the work of the welding robot 6 from spreading. Moreover, the exhaust fan 406 installed inside the protection module 4 extracts the fumes and welding dust, sends them into the annular filter pipe 408 through the conveying pipe 407 for preliminary filtration, and then the discharge fan 409 discharges them into the adsorption box 402 for activated carbon adsorption, and then discharges them through the pipeline connected to the top of the adsorption box 402. Compared with the traditional exposed welding, the entire welding process is carried out in a relatively sealed environment, and is equipped with a dedicated air extraction, filtration, and adsorption structure, so that the fumes and welding dust generated during the entire welding can be processed in time and will not be emitted to affect the health of the operators and the working environment.
