Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a welding tool for a riser on a motorcycle frame. Background Art

[0002] Existing motorcycle frames, such as Figure 1 The frame shown is welded from multiple metal pipes. In traditional forming, the frame is mostly divided into a front half and a rear half. For example, the front standpipe of the front half is welded to the left and right main pipes and the left and right tube pipes to form the front half frame, and then the taillight connecting pipe is welded to the left and right upper tail pipes and the left and right lower tail pipes to form the rear half frame. Thereafter, the front half frame main pipe is welded to the upper tail pipe of the rear half frame, and the tube pipe of the front half frame is welded to the lower tail pipe of the rear half frame. For example, a combination clamp of a right front half body tooling of a frame with patent announcement number CN207656162U is provided. However, due to the different stress release of the front and rear half frames and the different deformation amounts after welding, this welding method forces it to be difficult to align the left and right splicing of the front and rear half frames when welding. It is often necessary to correct the size before welding or to splice and shape the front and rear half frames for a long time, and then weld them after the size can be butted. This method makes the frame welding time-consuming and very difficult to correct the shape of the metal steel pipe after welding, which is not conducive to production.

[0003] The inventor tried to break the front-to-back assembly mode and change it to a left-to-right assembly mode, that is, to divide the frame into left and right half frames, the front standpipe assembly, the rear taillight assembly, and the middle connecting cross pipes that span the left and right half frames ( Figure 2 and Figure 3 ), during production, the half frame, the riser assembly, and the taillight assembly are first welded into an independent whole, and then the left and right half frames are assembled with the riser assembly, the rear taillight assembly, and each connecting cross tube and welded together; among them, the parts of the riser assembly that need to be welded on the riser mainly include the triangular reinforcement plate, the lamp holder seat, and the lock seat. If the installation position of each part is manually marked on the riser, and then the welding is performed according to the marked line, there will be marking errors on the one hand, and the production efficiency will be low on the other hand. Utility Model Content

[0004] The utility model aims to provide a tool for welding a riser on a motorcycle frame, so as to meet the use requirements of welding a triangular reinforcement plate, a lamp holder seat and a lock seat on the riser of the motorcycle and improve the production efficiency and the dimensional accuracy after subsequent welding compared with the traditional marking and positioning method.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixture for welding the upper riser of a motorcycle frame, including fixture assembly one and fixture assembly two. Both fixture assembly one and fixture assembly two include a clamp for clamping the riser. The clamp includes a positioning plug and a clamping block that can move away from or close to the positioning plug. The clamping block and the positioning plug clamp the riser from both ends of the riser. The clamp of fixture assembly one is vertically arranged, and the clamp of fixture assembly two is horizontally arranged;

[0007] Both fixture assembly one and fixture assembly two also include a lamp holder seat locator and a lock seat fixing column. The lamp holder seat locator includes a driver and a push rod. The push rod is provided with a positioning pin. The positioning pin can be inserted into the designed hole of the lamp holder under the drive of the driver, and the lamp holder is abutted against the outer periphery of the riser. The lock seat positioning column is provided with a threaded hole, and the lock seat can be threadedly connected to the lock seat positioning column;

[0008] A simulation trustee is fixed on fixture assembly two. The triangular reinforcing plate can be buckled on the simulation trustee. The lamp holder seat locator and the simulation trustee of fixture assembly two are located on the left and right sides of the riser.

[0009] The principle and advantages of this solution are as follows: When adopting this solution, the relative fixation of the riser with the lamp holder and the lock seat is realized through fixture assembly one. Then, a welding torch is used to weld the lamp holder fixed on fixture assembly one to the riser and the lock seat to the riser. After the parts on fixture assembly one are welded, the riser with the lamp holder and the lock seat is placed on fixture assembly two. The clamp, lamp holder seat locator, and lock seat locator of fixture assembly two fix the riser. Then, the positioning of the triangular reinforcing plate is facilitated through the simulation trustee to facilitate the welding of the triangular reinforcing plate to the riser, and the side seams of the lamp holder / lock seat that are not convenient to weld on fixture assembly one are supplemented to improve the connection strength between the lamp holder / lock seat and the riser.

[0010] Compared with the prior art, this solution does not require manual scribing for part positioning, so it helps to ensure the dimensional accuracy and position accuracy of the welded riser assembly, and helps to improve production efficiency compared with the prior art.

[0011] In addition, since both fixture assembly one and fixture assembly two use the clamp, lamp holder seat locator, and lock seat positioning column to complete the relative position fixation of the riser with the lamp holder / lock seat, the positions of the two fixture assemblies for clamping the parts are the same, which helps to improve the stability and consistency of the production quality of the riser assembly.

[0012] Preferably, as an improvement, the positioning plug is provided with a through hole. The through hole is opened on the outer periphery of the positioning plug and penetrates the outer periphery. The top surface of the positioning plug facing the riser is provided with a communication hole, and the communication hole is communicated with the through hole to help dissipate heat during the processing of the riser.

[0013] Preferably, as an improvement, a bottom support column is further fixedly installed on the second fixture assembly. The bottom support column is located below the clamping block and is used to support the riser pipe.

[0014] Preferably, as an improvement, the bottom support column is provided with an arc-shaped groove that fits the outer circumference of the riser pipe to improve the support strength for the riser pipe and further define the axial direction of the riser pipe.

[0015] Preferably, as an improvement, the lamp holder positioner further includes a fixedly installed guide sleeve, and the push rod is slidably connected in the guide sleeve to ensure the stability of the push rod during movement.

[0016] Preferably, as an improvement, the lamp holder positioner in the first fixture assembly includes at least two push rods, and an intermediate mounting block is fixed between all the push rods and the output end of the driver, so that one driver can drive all the push rods to move synchronously at the same time.

[0017] Preferably, as an improvement, the clamp further includes a linear pusher. The output end of the linear pusher is fixed with a clamping block, and the linear driver is used to drive the clamping block to move away from or close to the positioning pin. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiment is basically as shown in the appendix Figures 4 to 9 shown.

[0034] A welding tool for the upper riser pipe of a motorcycle frame, including a workbench surface 30 and a fixture assembly one 10 and a fixture assembly two 20 fixed on the workbench surface 30. Both the fixture assembly one 10 and the fixture assembly two 20 include a clamp for clamping the riser pipe 100

[0035] The clamp includes a linear pusher 11, a positioning plug 12, and a clamping block 13 that can move away from or close to the positioning plug 12. The linear pusher 11 is fixed on the workbench surface 30, and the output end of the linear driver 61 is fixed with the clamping block 13. The linear driver 61 is used to drive the clamping block 13 to move away from or close to the positioning plug 12. The linear driver 61 adopts a cylinder in this embodiment.

[0036] The clamping block 13 and the positioning insertion post 12 clamp the riser pipe 100 from both ends of the riser pipe 100. A through hole 121 is machined on the positioning insertion post 12. The through hole 121 is opened on the outer periphery of the positioning insertion post 12 and penetrates the outer periphery. A communication hole 122 is opened on the top surface of the positioning insertion post 12 facing the riser pipe 100. The communication hole 122 communicates with the through hole 121 to help dissipate heat from the riser pipe 100 during the processing. The clamp of the first fixture assembly 10 is arranged vertically, and the clamp of the second fixture assembly 20 is arranged horizontally;

[0037] Both the first fixture assembly 10 and the second fixture assembly 20 further include a lamp holder seat locator 2 and a lock seat fixing post 3. The lamp holder seat locator 2 includes a fixedly installed lamp holder seat driver 21 and a push rod 22 installed at the output end of the lamp holder seat driver 21. A positioning pin is provided on the push rod 22. The positioning pin can be inserted into the design hole of the lamp holder 101 under the drive of the lamp holder seat driver 21, and the lamp holder 101 is abutted against the outer periphery of the riser pipe 100. The lamp holder seat locator 2 further includes a fixedly installed guide sleeve 23. The push rod 22 is slidably connected in the guide sleeve 23 to ensure the stability of the movement of the push rod 22. In this embodiment, the lamp holder seat driver 21 also uses a cylinder, and the lamp holder seat driver 21 in the second fixture assembly 20 is not shown.

[0038] The lock seat 102 positioning post is provided with a threaded hole, and the lock seat 102 can be threadedly connected to the lock seat 102 positioning post.

[0039] A simulation trustee 4 is fixed on the second fixture assembly 20. The triangular reinforcing plate 103 can be buckled on the simulation trustee 4. The lamp holder seat locator 2 and the simulation trustee 4 of the second fixture assembly 20 are located on the left and right sides of the riser pipe 100.

[0040] A bottom support post 5 is also fixedly installed on the second fixture assembly 20. The bottom support post 5 is located below the clamping block 13. The bottom support post 5 is used to support the riser pipe 100. The bottom support post 5 is provided with an arc groove that matches the outer periphery of the riser pipe 100 to improve the support strength of the riser pipe 100 and further limit the axial direction of the riser pipe 100.

[0041] The lamp holder seat locator 2 in the first fixture assembly 10 includes at least two push rods 22. An intermediate mounting block 24 is fixed between all the push rods 22 and the output end of the driver so that one driver can drive all the push rods 22 to move synchronously at the same time. In this embodiment, the lamp holder 101 includes an upper seat and a lower seat. The number of push rods 22 is three. The first push rod 22 and the second push rod 22 counted from top to bottom are directly fixed with positioning pins to position and press the upper seat of the lamp holder 101 through the two positioning pins. The free end of the lowermost push rod 22 is fixed with a connecting plate, and two positioning pins are fixed on the connecting plate. These two positioning pins are used to position and press the lower seat of the lamp holder 101.

[0042] There is only one push rod 22 on the fixture assembly two 20. Since the lamp holder base 101 is already welded to the vertical pipe 100 at this time, the push rod 22 is used to position the lamp holder base 101 at this time.

[0043] When adopting this embodiment, the relative fixation of the vertical pipe 100 with the lamp holder base 101 and the lock base 102 is realized through the fixture assembly one 10. Then, the lamp holder base 101 fixed on the fixture assembly one 10 is welded to the vertical pipe 100 and the lock base 102 is welded to the vertical pipe 100 by using a welding torch. After the parts on the fixture assembly one 10 are welded, the vertical pipe 100 with the lamp holder base 101 and the lock base 102 is placed on the fixture assembly two 20. The vertical pipe 100 is fixed by the clamp, the lamp holder positioner 2, and the lock base 102 positioner of the fixture assembly two 20. Then, the positioning of the triangular reinforcing plate 103 is facilitated through the simulation carrier 4 to facilitate the welding of the triangular reinforcing plate 103 to the vertical pipe 100, and the side seams that are not convenient to weld for the lamp holder base 101 / lock base 102 on the fixture assembly one 10 are supplemented to improve the connection strength between the lamp holder base 101 / lock base 102 and the vertical pipe 100.

[0044] Compared with the prior art, this embodiment does not require manual scribing for part positioning, so it helps to ensure the dimensional accuracy and position accuracy of the vertical pipe 100 assembly after welding, and helps to improve production efficiency by comparison.

[0045] In addition, since both the fixture assembly one 10 and the fixture assembly two 20 use the clamp, the lamp holder positioner 2, and the lock base 102 positioning post to complete the relative position fixation of the vertical pipe 100 with the lamp holder base 101 / lock base 102, it helps to improve the stability and consistency of the production quality of the vertical pipe 100 assembly.

[0046] Embodiment Two

[0047] Combined with Figures 10 to 13 , compared with Embodiment One, in this Embodiment Two, a thrust device for positioning the triangular reinforcing plate 103 is installed on the fixture assembly two 20. The thrust device includes a linear driver 61, a push block 62, and a pressing rod 63. The pressing rod 63 is fixed on the push block 62, the push block 62 is fixed on the output end of the linear driver 61, and the linear driver 61 is fixedly installed; the pressing rod 63 is a stepped rod, and the number of the pressing rods 63 is two. The pressing rods 63 are used to insert into the process holes of the triangular reinforcing plate 103 and press the triangular reinforcing plate 103 against the simulation carrier 4. The linear driver 61 is used to drive the push block 62 and the pressing rod 63 to move away from or close to the simulation carrier 4.

[0048] By adding the thrust device in this embodiment, the triangular reinforcing plate 103 can be accurately positioned and supported, which helps to improve the position accuracy of the welding of the triangular reinforcing plate 103.
