Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle technology, specifically to a pipe welding fixture. Background Technology
[0002] As a crucial component of bicycles, the quality and performance of the bicycle fork tubes directly affect the stability of the entire vehicle and the safety of the rider. Welding, as one of the key processes in fork tube manufacturing, directly impacts welding quality and production efficiency through the technological level of the equipment used. Bicycle fork tube welding equipment is primarily used to connect the top tube, bottom tube, and seat tube of the fork together through welding, forming a stable fork structure.
[0003] Patent publication number CN219665394U discloses a welding equipment for bicycle upper and lower fork tube fittings, including a gantry mechanism, a welding mechanism, and a turntable mechanism. The welding mechanism is fixed to the moving end of the gantry mechanism and has a rotatable welding end. The turntable mechanism has a rotatable turntable, and at least two clamps are fixed to the top of the turntable. The clamps are capable of clamping or releasing workpieces.
[0004] To address the issue that manual welding of bicycle fork fittings is commonly used, which is prone to problems such as large variations, low production efficiency, and poor stability, existing technology involves fixing the bicycle fork fittings and fittings onto a fixture. Then, the workpiece and fixture are rotated by a turntable mechanism to a position close to a gantry mechanism. The welding mechanism, driven by the gantry mechanism, approaches the workpiece fixed on the fixture and performs welding. However, this method still suffers from poor fixing of the fittings, inability to adjust the welding spacing, and misalignment during welding, leading to problems with the stability, convenience, and accuracy of the device's adjustment and use.

[0025] The present invention will be further described in detail below with reference to embodiments:
[0026] Example 1
[0027] like Figure 1-6As shown, this utility model provides a pipe welding fixture, including a support mechanism 1. A fixing mechanism 2 is provided inside the support mechanism 1. The fixing mechanism 2 includes a limiting plate 201. A first sliding groove 202 is formed on the front of the limiting plate 201. A rack 203 is slidably connected inside the first sliding groove 202. A second sliding groove 204 is formed on the front of the rack 203. A first clamping block 205 is fixedly connected to the front of the rack 203. A second clamping block 206 is slidably connected inside the second sliding groove 204. The first clamping block 205 and the second clamping block 206 cooperate with each other. Rubber pads are provided on the inner sides of both the first clamping block 205 and the second clamping block 206. A spring 207 is fixedly connected to the outside of the second groove 206. The spring 207 is movably installed inside the second groove 204. A base plate 208 is fixedly connected to the lower back of the limiting plate 201. A rotating rod 209 and a rotating rod 210 are rotatably connected to the top surface of the base plate 208. A motor 211 is fixedly connected to the top surface of the base plate 208. A rotating rod 212 is fixedly connected to the output end of the motor 211. A gear 213 is fixedly connected to the surface of the rotating rod 209 and the rotating rod 212. A gear 214 is fixedly connected to the surface of the rotating rod 210. Gears 213 and 214 cooperate with the rack 203.
[0028] In this embodiment, when it is necessary to fix the left and right fork arms of the bicycle front fork, the second clamping block 206 is pulled to slide within the second groove 204 away from the first clamping block 205. The second clamping block 206 compresses the first spring 207, locking the left and right fork arms between the first clamping block 205 and the second clamping block 206 respectively. The second clamping block 206 is released, and the first spring 207 relaxes, pushing the second clamping block 206 to slide towards the first clamping block 205. The first clamping block 205 and the second clamping block 206 clamp the left and right fork arms. The rubber pads on the inner sides of the first clamping block 205 and the second clamping block 206 are used to improve the limiting effect on the left and right fork arms and prevent the first clamping block 205 and the second clamping block 206 from scratching the left and right fork arms, thereby fixing the left and right fork arms. The clamping blocks 205 and 206 are configured in four sets to fix the two ends of the left and right forks respectively, which improves the stability and convenience of fixing the left and right forks. When it is necessary to adjust the welding spacing of the left and right forks, the motor 211 is started to rotate the rotating rod 212. The rotating rod 212 drives the gear 213, gear 214, rotating rod 210, and rotating rod 209 to rotate. The gear 213 drives the rack 203 to slide left and right in the slide groove 202. The rack 203 drives the clamping blocks 205 and 206 to move left and right, thereby adjusting the welding spacing of the left and right forks. This improves the convenience and applicability of the device for welding left and right forks with different spacings.
[0029] Example 2
[0030] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support mechanism 1 includes a support leg 101, a support base 102 is fixedly connected to the top of the support leg 101, the support base 102 is movably connected to the base plate 208, a support base plate 103 is fixedly connected to the inner side of the support leg 101, a telescopic rod 104 is fixedly connected to the top surface of the support base plate 103, the top end of the telescopic rod 104 passes through the support base 102 and is fixedly connected to the base plate 208, support side plates 105 are fixedly connected to the top surfaces of both ends of the support base 102, the support side plates 105 are slidably connected to the limiting plate 201, a top plate 106 is fixedly connected to the top of the support side plates 105, a sliding groove 107 is provided on the front of the top plate 106, a clamping block 108 is slidably connected inside the sliding groove 107, a rubber pad is provided on the inner side of the clamping block 108, and a spring 109 is fixedly connected to the outer side of the clamping block 108, and the spring 109 is movably installed inside the sliding groove 107.
[0031] In this embodiment, when it is necessary to fix the straight tube of the bicycle front fork, the two clamping blocks 108 are pulled outward and slide outward within the sliding groove 107. The clamping blocks 108 compress the spring 109, locking the straight tube of the front fork between the two clamping blocks 108. Then, the clamping blocks 108 are released, and the spring 109 relaxes, pushing the clamping blocks 108 to clamp both sides of the straight tube. The rubber pad on the inner side of the clamping blocks 108 is used to improve the limiting effect of the clamping blocks 108 on the straight tube and to prevent the clamping blocks 108 from scratching the straight tube, thereby fixing the straight tube of the front fork and improving the performance of this device. The stability and convenience of the fixed straight tube are achieved when welding the left and right fork arms and the straight tube of the front fork. The telescopic rod 104 on the support base plate 103 is activated. The top of the telescopic rod 104 passes through the inside of the support base 102 and pushes the base plate 208 upward. The base plate 208 drives the limiting plate 201 to slide on the inside of the support side plate 105 toward the top plate 106, so that the fixed left and right fork arms are close to the fixed straight tube for easy welding. This avoids the two from shifting during welding and improves the accuracy and convenience of welding bicycle front forks with this device.
[0032] The working principle of this pipe fitting welding fixture will be explained in detail below.
[0033] like Figure 1-6As shown, when it is necessary to fix the left and right fork arms of the bicycle front fork, pull the second clamp 206 to slide it in the second groove 204 away from the first clamp 205. The second clamp 206 compresses the first spring 207, locking the left and right fork arms between the first clamp 205 and the second clamp 206 respectively. Release the second clamp 206, and the first spring 207 relaxes, pushing the second clamp 206 to slide towards the first clamp 205. The first clamp 205 and the second clamp 206 clamp the left and right fork arms. The rubber pads on the inner sides of the first clamp 205 and the second clamp 206 are used to improve the stability of the bicycle front fork. The left and right fork arms are limited to prevent the clamping blocks 205 and 206 from scratching them, thus fixing the left and right fork arms. Clamping blocks 205 and 206 are arranged in four sets to fix both ends of the left and right fork arms respectively. When the welding spacing of the left and right fork arms needs to be adjusted, the motor 211 is started to rotate the rotating rod 212. The rotating rod 212 drives the gears 213, 214, 210, and 209 to rotate. The gear 213 drives the rack 203 to slide left and right in the slide groove 202. When the rack 203 moves, it drives the clamping blocks 1 205 and 206 to move left and right, thereby adjusting the welding distance between the left and right fork arms. When it is necessary to fix the straight tube of the bicycle front fork, the two clamping blocks 3 108 are pulled outward and slide outward in the sliding groove 3 107. The clamping blocks 3 108 compress the spring 2 109, clamping the straight tube of the front fork between the two clamping blocks 3 108 and then releasing the clamping blocks 3 108. The spring 2 109 relaxes and pushes the clamping blocks 3 108 to clamp the two sides of the straight tube. The rubber pad on the inside of the clamping blocks 3 108 is used to improve the clamping of the straight tube. The tube is positioned to prevent the clamping block 108 from scratching the straight tube, thus fixing the straight tube of the fork. When welding the left and right fork arms and the straight tube of the fork is required, the telescopic rod 104 on the support base plate 103 is activated. The top of the telescopic rod 104 passes through the inside of the support base 102 and pushes the base plate 208 upward. The base plate 208 drives the limiting plate 201 to slide from the inside of the support side plate 105 to the top plate 106, so that the fixed left and right fork arms are close to the fixed straight tube for easy welding and to prevent the two from shifting during welding.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
