[0026] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 2 As shown, this utility model proposes a welding equipment for assembling and splicing motorcycle frames, including a base 8, a frame head positioning mechanism 9, a frame tail positioning mechanism 10, and a wing plate positioning device 11.

[0028] like Figure 2 and 3As shown, the frame positioning mechanism 9 includes an I-beam frame 12, which is screwed onto the base 8. A lower positioning seat 13 is screwed onto the top surface of the I-beam frame 12, and the lower positioning seat 13 abuts against the bottom surface of the frame head 2. A lower positioning head 14, which engages with the front positioning hole 3, is fixedly connected to the top surface of the lower positioning seat 13. An "L"-shaped electric cylinder frame 15 is screwed onto the top surface of the I-beam frame 12, and a drive electric cylinder 16 is fixedly mounted on the top surface of the electric cylinder frame 15. The piston rod of the drive electric cylinder 16 passes through the electric cylinder frame 15 and is connected to an upper positioning seat 17. The upper positioning seat 17 abuts against the top surface of the frame head 2, and an upper positioning head 18, which engages with the front positioning hole 3, is fixedly connected to the bottom surface of the upper positioning seat 17.

[0029] like Figure 2 and 4 As shown, there are two tail positioning mechanisms 10, which are symmetrically arranged on both sides of the tail 4. Each tail positioning mechanism 10 includes an electric cylinder seat 19, which is screwed to the base 8. A working electric cylinder 20 is fixedly installed on the side wall of the electric cylinder seat 19. The piston rod of the working electric cylinder 20 passes through the electric cylinder seat 19 and is welded to a side abutment 21. The side abutment 21 is pressed against the side wall of the tail 4. A fixed hole post 22 that is inserted into the rear positioning hole 5 is fixedly connected to the end of the side abutment 21 away from the working electric cylinder 20.

[0030] like Figure 2 and 5 As shown, there are two wing plate positioning devices 11, symmetrically arranged on both sides of the middle of the frame body 1. Each wing plate positioning device 11 includes a positioning block 23, positioning rods 24, and a driving mechanism. The positioning block 23 is used to abut against and limit the wing plate 6. The side wall of the positioning block 23 facing the frame body 1 abuts against the side wall of the wing plate 6 away from the frame body 1. Two round rod-shaped positioning rods 24 are fixedly connected to the side wall of the positioning block 23 facing the frame body 1. The two positioning rods 24 are respectively inserted into the two central positioning holes 7 on the wing plate 6. The diameter of the positioning rods 24 and the central positioning holes 7 is the same. When the wing plate 6 is placed on the wing plate positioning device 11, the side wall of the wing plate 6 away from the frame body 1 abuts against the side wall of the positioning block 23 facing the frame body 1, and the two positioning rods 24 pass through the two central positioning holes 7 of the same diameter.

[0031] The driving mechanism is used to drive the positioning block 23 to make reciprocating linear motions toward or away from the frame body 1. The driving mechanism includes a column 25, a fixing plate 26, a driving slide 27, a straight toothed track 28, a driving gear 30, and a driving wheel assembly.

[0032] like Figure 5 and 6As shown, four rectangular columns 25 are fixed on the top surface of the base 8, and a fixing plate 26 is fixed on the top surface of the four columns 25. The drive slide 27 is slidably set on the fixing plate 26, and the positioning block 23 is fixedly connected to the outer side wall of the drive slide. The positioning block 23 can follow the drive slide 27 to make reciprocating linear motion.

[0033] like Figure 5 and 6 As shown, the spur gear 28 is fixedly connected to the top surface of the fixed plate 26. The length direction of the spur gear 28 is the same as the length direction of the fixed plate 26, and the length direction of the spur gear 28 is the same as the moving direction of the driving mechanism. A slide groove 29 is provided on the bottom surface of the driving slide 27, and the driving gear 30 is rotatably disposed in the slide groove 29, meshing with the spur gear 28.

[0034] like Figure 5 and 6 As shown, the drive wheel assembly is used to drive the drive gear 30 to rotate, thereby driving the drive slide 27 to reciprocate linearly along the length of the spur track 28. The drive wheel assembly includes a self-locking motor 31, which is fixedly installed on the top surface of the drive slide 27. The output shaft of the self-locking motor 31 passes through the seat wall of the drive slide 27 and extends into the slide groove 29. After the output shaft of the self-locking motor 31 extends into the slide groove 29, a bevel gear 32 is coaxially arranged thereon. A horizontal shaft 33 is rotatably arranged in the slide groove 29. A driven bevel gear 34 is coaxially mounted on the horizontal shaft 33 via a key connection. The driven bevel gear 34 meshes with the bevel gear 32. The horizontal shaft 33 is coaxially connected to the drive gear 30 via a key connection.

[0035] like Figure 5 and 6 As shown, an upper ring seat 35 is fixedly connected to the top cavity wall of the slide groove 29. The upper ring seat 35 is circular, and the middle part of the upper ring seat 35 is an upper groove 36. An upper bearing 37 is interference-fitted into the upper groove 36. The upper bearing 37 is mounted on the output shaft of the self-locking motor 31, so the output shaft of the self-locking motor 31 can rotate relatively stably.

[0036] like Figure 5 and 6 As shown, side ring seats 38 are fixedly connected to the two opposite side cavity walls of the slide groove 29. The side ring seats 38 are circular. The middle part of the side ring seats 38 is a side groove 39. A side bearing 40 is interference-fitted into the side groove 39. The side bearing 40 is fitted onto the end of the horizontal shaft 33, so that the horizontal shaft 33 can rotate stably.

[0037] like Figure 5 and 6As shown, a track through hole 41 is provided on the drive slide 27 along the feed direction of the drive mechanism. The track through hole 41 is a rectangular hole and is connected to the slide groove 29. The track through hole 41 is used for the straight tooth track 28 to pass through.

[0038] like Figure 5 and 6 As shown, two linear slide rails 42 are screwed onto the top surface of the fixed plate 26. The two linear slide rails 42 are located on both sides of the driving slide 27, and the length direction of the linear slide rails 42 is the same as the feed direction of the driving mechanism. A side plate 43 is fixedly connected to the side wall of the driving slide 27 facing the linear slide rails 42. A rib plate 44 is fixedly connected between the top surface of the side plate 43 and the side wall of the driving slide 27. A linear slider 45 that slides with the linear slide rails 42 is screwed onto the bottom surface of the side plate 43, thus restricting the driving slide 27 to move along the width direction of the fixed plate 26.

[0039] The detailed welding process of the wing plate 6 in this embodiment is as follows:

[0040] S1, the worker passes two positioning rods 24 through the two central positioning holes 7 of the wing plate 6, and makes the wing plate 6 fit against the side wall of the positioning block 23 facing the frame body 1.

[0041] S2, the self-locking motor 31 drives the bevel gear 32 to rotate, and the driven bevel gear 34 meshing with the bevel gear 32 rotates accordingly, which in turn drives the horizontal shaft 33 to rotate. The rotation of the horizontal shaft 33 will drive the drive gear to rotate. Since the drive gear meshes with the spur track 28, it drives the slide 27 to drive the wing plate 6 to move closer to the frame body 1 until the wing plate 6 is attached to the side wall of the frame body 1. The output shaft of the self-locking motor 31 self-locks, so the wing plate 6 remains attached to the side wall of the frame body 1, which is convenient for workers to weld with a welding gun.

[0042] This welding equipment for assembling and splicing motorcycle frames utilizes a frame head positioning mechanism 9, a frame tail positioning mechanism 10, and a wing plate positioning device 11 to position the motorcycle frame and wing plate 6, which facilitates welding by workers, improves work efficiency, and reduces positioning errors.
