[0021] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0022] like Figures 1 to 6 As shown, an embodiment of the present invention provides a welding device for a tricycle frame, including a welding base 1, a crossbeam positioning component 2, a longitudinal frame positioning component 3, a stop frame mounting component 4, and a welding torch 5.

[0023] Specifically, the cross frame positioning component 2 and the longitudinal frame positioning component 3 are installed on the upper surface of the welding base 1, and the cross frame positioning component 2 and the longitudinal frame positioning component 3 respectively position and fix the cross frame and longitudinal frame of the tricycle frame.

[0024] The baffle mounting component 4 is movably installed on the welding base 1. The baffle mounting component 4 is used to move the baffle of the tricycle and to fix the baffle of the tricycle frame onto the crossbar of the tricycle frame, so as to complete the spatial layout and positioning of the frame components.

[0025] The welding torch 5 is mounted on the welding base 1, and the welding torch 5 is used to weld and fix the longitudinal frame and the stop frame at the connection position with the cross frame.

[0026] In this embodiment, when welding is required on the tricycle frame, the crossbeams and longitudinal frames of the tricycle frame are placed on the welding base 1 according to design requirements and welding standards. The crossbeam positioning component 2 and the longitudinal frame positioning component 3 are then used to position and fix the crossbeams and longitudinal frames. Subsequently, the stopper mounting component 4 is used to move the stopper to the welding position of the crossbeam and until it is in contact with the welding position of the crossbeam, thus completing the spatial distribution and positioning of the crossbeams, longitudinal frames, and stopper of the tricycle frame. Finally, the welding torch 5 is used to weld the welding positions of the tricycle frame, effectively reducing component displacement and ensuring the welding quality of the tricycle frame.

[0027] Compared to existing technologies, this invention utilizes the cooperation between the cross-frame positioning component and the longitudinal frame positioning component to achieve rapid positioning between the cross-frame and longitudinal frame of the tricycle frame. This eliminates the need for adjustments and positioning of components during the welding process, significantly improving the welding efficiency of the tricycle frame. Furthermore, the cooperation between the cross-frame and longitudinal frame positioning components ensures accurate alignment between the cross-frame and longitudinal frame of the tricycle frame, resulting in precise welding at the welding points and effectively guaranteeing the welding quality of the tricycle frame. This invention is characterized by its simple structure and convenient operation.

[0028] It should be noted that after the welding operation of the first tricycle frame is completed, the positions of the cross frame positioning component 2 and the longitudinal frame positioning component 3 are basically determined. During the subsequent welding of the tricycle frame, it is not necessary to spend too much time adjusting the cross frame positioning component 2 and the longitudinal frame positioning component 3, which can effectively improve the welding efficiency of the tricycle frame.

[0029] Furthermore, the crossbeam positioning component 2 is provided in two pairs, and the two pairs of crossbeam positioning components 2 respectively position and fix the ends of the two crossbeams of the tricycle frame. The crossbeam positioning component 2 includes a mounting base 6, a positioning side plate 7, and a positioning pin 8.

[0030] Specifically, the upper surface of the mounting base 6 is provided with an adjustment groove 9, and the inner wall of the adjustment groove 9 is provided with positioning teeth 10 along its length.

[0031] Two positioning side plates 7 are arranged in parallel. The two positioning side plates 7 are detachably installed in the adjustment groove 9 through connecting strips 11, and the connecting strips 11 are engaged with the positioning teeth 10.

[0032] Multiple positioning pins 8 are provided, and the multiple positioning pins 8 are evenly distributed on the bottom surface of the mounting base 6. The welding base 1 is provided with positioning slots 12 that match the positioning pins 8.

[0033] In this embodiment, each pair of crossbeam positioning members 2 positions both ends of a crossbeam. When positioning the crossbeam, firstly, the distance between the two positioning side plates 7 is determined according to the width of the crossbeam, and the positioning side plates 7 are inserted into the adjusting groove 9. Then, according to the length of the crossbeam, the two crossbeam positioning members 2 located in the same pair are inserted into the positioning slots 12 on the welding base 1. Finally, the crossbeam to be welded is placed between the two crossbeam positioning members 2, completing the placement and positioning of the crossbeam.

[0034] The two pairs of crossbeam positioning components 2 are installed and inserted sequentially using this method. When installing the second pair of crossbeam positioning components 2, the spacing between the two pairs of crossbeam positioning components 2 needs to be adjusted to ensure that the spacing between the two crossbeams is sufficient for the placement and welding of the longitudinal frame.

[0035] In one specific embodiment, the connecting strip 11 includes a connecting strip 13 and an insert plate 14. The connecting strip 13 is fixedly connected to the top end of the positioning side plate 7 and the top end of the insert plate 14, and the connecting strip 13 is integrally formed with the positioning side plate 7 and the insert plate 14. The insert plate 14 is inserted into the adjusting groove 9, and the insert plate 14 is in close contact with the inner wall of the adjusting groove 9. The insert plate 14 has a groove 15 that matches the positioning teeth 10.

[0036] When adjusting the spacing between the two positioning side plates 7, the spacing between the two positioning side plates 7 is determined according to the width of the crossbeam. Then, the insert plate 14 at the end of the positioning side plate 7 is inserted into the adjustment groove 9, and the slot 15 on the insert plate 14 engages with the positioning tooth 10, thus completing the spacing adjustment operation of the positioning side plates 7.

[0037] In addition, multiple positioning slots 12 are provided, and the multiple positioning slots 12 are evenly distributed on the welding base 1. The positioning slots 12 are arranged in a matrix on the welding base 1, and the top of each positioning slot 12 has a chamfered structure. The multiple positioning slots 12 arranged in a matrix provide a large adjustment space when placing and positioning the crossbeam positioning component 2, thus facilitating welding operations on tricycle frames of different specifications.

[0038] Furthermore, multiple pairs of longitudinal frame positioning members 3 are provided, and multiple pairs of longitudinal frame positioning members 3 are inserted into the positioning slot 12. The longitudinal frame positioning members 3 are distributed between the cross frame and the longitudinal frame of the tricycle frame, and are used to right-angle positioning and fix the cross frame and the longitudinal frame of the tricycle frame.

[0039] In this embodiment, the longitudinal frame positioning component 3 includes a positioning plate 16, a movable handle 17, and an adsorption magnetic sheet 18. The positioning plate 16 is a right-angled triangle, and a welding pre-reserved groove 19 is formed at the right-angle corner of the positioning plate 16. The movable handle 17 is fixedly disposed on the upper surface of the positioning plate 16, and the movable handle 17 is used to adjust the placement position of the positioning plate 16. The adsorption magnetic sheet 18 is embedded in the outer wall of the right-angle side of the positioning plate 16, and the outer surface of the adsorption magnetic sheet 18 is flush with the outer wall of the right-angle side of the positioning plate 16. The adsorption magnetic sheet 18 is magnetically adsorbed and connected to the cross or longitudinal frame of the tricycle.

[0040] After the crossbeams are positioned, multiple longitudinal frames are placed between the two crossbeams according to their welding positions. Then, the longitudinal frame positioning components 3 are used to position and fix the inner and outer sides of both ends of the longitudinal frames. Specifically, two positioning plates 16 are attached to the inner side of the crossbeams, and then moved along the inner side of the crossbeams and attached to the side of the longitudinal frames, so that the longitudinal frame between the two positioning plates 16 is in the welding position. Because the contact surfaces of the positioning plates 16 with the crossbeams and longitudinal frames are perpendicular, the crossbeams and longitudinal frames remain perpendicular, thus reducing the tilt of the longitudinal frames and ensuring the welding quality of the tricycle frame. Each longitudinal frame is then positioned in this manner.

[0041] It should be noted that the magnetic adsorption sheet 18 can also be set on the bottom surface of the positioning plate 16. After the welding operation of the tricycle frame is completed, there is no need to adjust the positioning plate 16. When welding the tricycle frames of the same batch, there is no need to adjust the position of the longitudinal frame adjustment component. The longitudinal frame can be directly placed on the corresponding longitudinal frame positioning component 3, thereby quickly completing the welding operation of the tricycle frame.

[0042] Furthermore, the baffle mounting component 4 includes a linear guide rail 20, a transport frame 21, a temporary mounting component, and a lifting and adjusting component 23.

[0043] Specifically, two linear guide rails 20 are arranged in parallel, and the two linear guide rails 20 are fixedly installed on the welding base 1.

[0044] The transport frame 21 is movably mounted on the linear guide rail 20, and the transport frame 21 is slidably arranged along the length direction of the linear guide rail 20.

[0045] The temporary mounting component is movably installed on the transport frame 21, and the temporary mounting frame 22 is slidably arranged along the height direction of the transport frame 21. The temporary mounting component is used to temporarily mount the frame of the tricycle.

[0046] The lifting adjustment component 23 is installed on the transport frame 21, and the lifting adjustment frame is connected to the temporary placement frame 22. The lifting adjustment frame is used to adjust the height of the temporary placement frame 22 and drive the tricycle frame stop to come into contact with the crossbar.

[0047] In this embodiment, after the horizontal and vertical frames are positioned, the retaining frame placed on the temporary mounting piece is moved via the transport frame 21 to above the welding position of the horizontal frame. Then, the retaining frame is lowered using the lifting adjustment component 23, bringing it into contact with the upper surface of the horizontal frame. Due to the friction between the retaining frame and the upper surface of the horizontal frame, the retaining frame and transport frame 21 are stably maintained in their current positions. Finally, the welding torch 5 is used to perform welding operations at the welding positions between the horizontal frame, vertical frame, and retaining frame.

[0048] Furthermore, the temporary mounting frame 22 includes a positioning slide 24, an extension frame 25, and a clamping positioning frame 26.

[0049] Specifically, two positioning sleeves 24 are symmetrically arranged, and the two positioning sleeves 24 are slidably mounted on the transport frame 21 through linear bearings.

[0050] The extension frame 25 is fixedly installed on the two positioning sleeves 24.

[0051] Multiple clamping and positioning frames 26 are provided, and multiple clamping and positioning frames 26 are fixedly installed on the extension frame 25. The clamping and positioning frames 26 are used to place and position the tricycle frame guard.

[0052] In this embodiment, the extension frame 25 is vertically and slidably mounted on the transport frame 21 via the positioning sleeve 24, and then the clamping positioning frame 26 drives the stop frame to move up and down. When the stop frame placed on the clamping positioning frame 26 reaches above the welding position of the cross frame, the extension frame 25 drives the stop frame to descend to the welding position of the cross frame. When the stop frame is in contact with the welding position of the cross frame, the welding torch 5 can be used to perform the welding operation at the welding position.

[0053] In one specific embodiment, the clamping and positioning frame 26 includes a positioning frame body 27, on which an L-shaped placement positioning groove 28 is formed, with the opening of the placement positioning groove 28 facing upwards. When placing the stop, the stop is placed vertically into the placement positioning groove 28 and then horizontally moved to the end opposite the opening. During the downward movement of the stop caused by the clamping and positioning frame 26, the inner top surface of the placement positioning groove 28 restricts the upward movement of the stop, ensuring a tight fit between the stop and the welding position of the crossbeam, thus facilitating welding operations at the welding position between the crossbeam and the stop.

[0054] Furthermore, the lifting adjustment component 23 includes an adjustment screw 29, a worm gear 30, and an adjustment handle 31.

[0055] Specifically, the adjusting screw 29 is vertically and rotatably mounted on the transport frame 21, and the adjusting screw 29 is threadedly connected to the extension frame 25.

[0056] The worm gear 30 is installed between the transport frame 21 and the adjusting screw 29, and the worm gear 30 is used to drive the adjusting screw 29 to rotate in the forward or reverse direction.

[0057] The adjustment handle 31 is fixedly installed at the input end of the worm gear 30, and the adjustment handle 31 is located on the outer side of the top of the transport frame 21.

[0058] The worm gear 30 includes a transmission worm gear and a drive worm. The transmission worm gear is fixedly installed on the top of the adjusting screw 29, and the drive worm is rotatably installed on the transport frame 21. The inner end of the drive worm is meshed with the transmission worm gear, and the outer end of the drive worm is fixedly connected to the adjusting handle 31.

[0059] When connecting the stop and the crossbeam, the transport frame 21 is used to move the stop directly above the welding position of the crossbeam. Then, the lifting adjustment component 23 is used to lower the stop located in the clamping and positioning frame 26, allowing the stop to connect with the welding position of the crossbeam. The specific method for lowering and adjusting the stop is as follows: Rotating the adjusting handle 31 causes the adjusting screw 29 to rotate via the transmission action of the worm gear 30. During the rotation of the adjusting screw 29, the extension frame 25, which is threadedly connected to it, cannot rotate with the adjusting screw 29 due to the restriction of the transport frame 21; the extension frame 25 can only move along the length of the adjusting screw 29. The direction of movement of the extension frame 25 is controlled by the rotation direction of the adjusting handle 31. When the extension frame 25 drives the stop frame located within the clamping and positioning frame 26 to contact the welding position of the cross frame, the connection between the stop frame and the cross frame is completed.

[0060] Due to the self-locking effect of the worm gear 30, the adjusting screw 29 remains stable and stationary when the adjusting handle 31 is not rotated, thereby ensuring that the stop frame remains stably in contact with the cross frame and effectively maintaining the docking state between the stop frame and the cross frame, thus guaranteeing the welding quality of the tricycle frame.

[0061] Compared with the prior art, the present invention has at least the following beneficial effects: This invention utilizes the cooperation between the cross-frame positioning component and the longitudinal frame positioning component to achieve rapid positioning between the cross-frame and longitudinal frame of the tricycle frame. This eliminates the need for adjustments and positioning of components during welding, significantly improving the welding efficiency of the tricycle frame. Furthermore, the cooperation between the cross-frame and longitudinal frame positioning components ensures accurate alignment between the cross-frame and longitudinal frame of the tricycle frame, resulting in precise welding at the welding points and effectively guaranteeing the welding quality of the tricycle frame. It features a simple structure and convenient operation.

[0062] Furthermore, the present invention utilizes a baffle mounting component to transport the baffle in the tricycle frame. Simultaneously, when the baffle moves to the welding position, the height of the baffle is adjusted to ensure close contact between the baffle and the crossbar, achieving precise alignment of the welding position between the baffle and the crossbar, effectively guaranteeing the welding quality of the tricycle frame.

[0063] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
