They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-7 As shown, this utility model specifically relates to a welding fixture for a front support assembly of a children's stroller, including a base 100 and a front support assembly 200 disposed on the base 100, wherein the front support assembly 200 is composed of a support tube 210 and a connecting tube 220. One end of the support tube 210 is provided with a positioning device 110, and the other end of the support tube 210 is provided with a pressing and fixing device 120. The positioning device 110 and the pressing and fixing device 120 cooperate with each other to fix the position of the support tube 210. The base 100 is also provided with an abutting device 130 for use with the connecting pipe 220, through which the connecting pipe 220 is connected to the support pipe 210; The abutting device 130 consists of a pressing device 131 and a limiting device 132. The pressing device 131 includes a pressing seat 1311, a bearing seat 1312 disposed on the pressing seat 1311, and a clamping assembly disposed on the pressing seat 1311. The limiting device 132 includes a connecting rod 1322 and an abutting assembly 1323 for driving the connecting rod 1322 to move. The connecting rod 1322 can pass through the bearing seat 1312 and one end of the connecting pipe 220 in sequence. The position of the connecting tube 220 on the bearing seat 1312 is adjusted by the connecting rod 1322 and fixed by the clamping assembly so that the other end of the connecting tube 220 abuts against the support tube 210.

[0023] It should be noted that although the stroller front support assembly 200 consists of two parts, a support tube 210 and a connecting tube 220, both the support tube 210 and the connecting tube 220 are irregular square parts with curved surfaces. Furthermore, the welding positions of the support tube 210 and the connecting tube 220 are at a certain angle. Therefore, if personnel weld directly without positioning, the next step of the process will inevitably be impossible to complete.

[0024] When welding is required on the front bracket assembly 200, firstly, the support tube 210 is placed on the base 100. The basic position of the support tube 210 is determined by the positioning device 110 at one end of the support tube 210, and then the pressing and fixing device 120 is used to fix the support tube 210 in place, preventing positional displacement during the welding process. Next, the connecting tube 220 is placed on the support seat 1312, and the clamping component is simultaneously in a pre-clamping state, so that the clamping end of the clamping component is in contact with the upper end of the connecting tube 220, but without affecting the linear movement of the connecting tube 220 within the support seat 1312.

[0025] From this point on, the connecting pipe 220 is provided with a through hole for use with the connecting rod 1322. The connecting rod 1322 passes through the bearing seat 1312 and the connecting pipe 220, and abuts against the connecting rod 1314 through the limiting nut 1324 provided on the connecting rod 1322, so that the connecting pipe 220 is moved to the designated position. When the connecting pipe 220 reaches the designated position, the clamping assembly clamps and fixes the connecting pipe 220 to ensure that the position of the connecting pipe 220 will not shift again. At this time, the connecting pipe 220 and the support rod 1313 abut against each other, which makes it convenient for personnel to directly weld at the abutment.

[0026] The positioning device 110 includes a positioning seat 111 disposed on the base 100. The positioning seat 111 is provided with a support head 112 for use with the support tube 210. The support head 112 can be inserted into the support tube 210 and fixed by a positioning pin assembly to limit the position of the support tube 210 and ensure the accuracy of the position.

[0027] The positioning pin assembly includes a crossbar 113, a pressure block 115 located at one end of the crossbar 113, and a pin 114 located inside the pressure block 115. The pin 114 can pass through the support tube 210 and the support head 112 in sequence, and is pressed and fixed to the surface of the support tube 210 by the pressure block 115.

[0028] The positioning device 110 also includes a driving component 116 disposed on the base 100 and capable of driving the positioning pin assembly to move.

[0029] Both the support tube 210 and the support head 112 are provided with pin holes. The position of the support tube 210 is determined by passing the pin holes of the support tube 210 and the support head 112 in sequence through the pin 114. Similarly, when the pin 114 is inserted into the pin hole, the pressure block 115 presses against the outer surface of the support tube 210 to fix the support tube 210 and ensure that the position of the support tube 210 will not shift.

[0030] Furthermore, the pressing and fixing device 120 fixes the other end of the support tube 210, thereby positioning the support tube 210 through the cooperation of the pressing and fixing device 120.

[0031] The drive assembly 116 includes a support frame 1162 fixed to the base 100, a connecting arm 1164, a drive arm 1163, a long arm 1165, and a manual lever 1161. One end of the connecting arm 1164 is rotatably connected to the support frame 1162, and the other end of the connecting arm 1164 is connected to one end of the long arm 1165. The other end of the long arm 1165 is connected to the crossbar 113; One end of the drive arm 1163 is rotatably connected to the connecting arm 1164, the other end of the drive arm 1163 is rotatably connected to the manual lever 1161, and one end of the manual lever 1161 is rotatably connected to the support frame 1162. When the manual lever 1161 rotates, the drive arm 1163 can abut or separate from the connecting arm 1164 to drive the crossbar 113 to press down or lift up. When the crossbar 113 presses down or lifts up, the support tube 210 and the support head 112 are positioned, fixed or released.

[0032] The structure of the clamping assembly is the same as that of the pressing and fixing device 120.

[0033] The clamping assembly includes a support rod 1313, a connecting rod 1314, a drive rod 1318, a handle 1317, and a long rod 1315. One end of the connecting rod 1314 is rotatably connected to the support rod 1313, and the other end of the connecting rod 1314 is fixedly connected to the long rod 1315. One end of the drive rod 1318 is rotatably connected to the connecting rod 1314, and the other end of the drive rod 1318 is rotatably connected to the handle 1317. One end of the handle 1317 is rotatably connected to the support rod 1313. When the handle 1317 is rotated, it drives the connecting rod 1314 and the long rod 1315 to rotate via the drive rod 1318.

[0034] The operating principle of the clamping component is the same as that of the driving component 116, and will not be described in detail here. Those skilled in the art can implement it based on the above description.

[0035] The clamping assembly also includes a contour block 1316 disposed on the long rod 1315 and used in conjunction with the connecting tube 220, through which the connecting tube 220 is connected to the support tube 210.

[0036] The contour block 1316 can cover the connecting tube 220. When the clamping component moves, the contour block 1316 presses down on the connecting tube 220 and fixes the connecting tube 220.

[0037] The limiting component is connected to the pressing seat 1311 via a long block 1321.

[0038] The above embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features within the technical scope disclosed in this utility model.
