Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle parts processing, specifically to a welding equipment for producing aircraft folding car brackets. Background Technology
[0002] As equipment used in airport ground services, the stability and reliability of the support structure of folding aircraft carts directly affect the safety and efficiency of baggage, meal, and cargo transportation. Traditional welding processes mostly rely on manual operation or semi-automatic equipment.
[0003] Chinese patent CN222370738U discloses a welding clamping tool for electric vehicle brackets, including a welding box. A motor is fixedly mounted at the bottom center of the welding box, and the motor's output shaft extends into the welding box and is fixedly sleeved onto a base. Two fixing plates are fixedly mounted between the top and bottom inner walls of the base. Each fixing plate has a circular hole at its center on one side, and a sleeve is rotatably mounted within both holes. The two ends of the sleeve extend out of the two holes and are threaded with screws. This utility model has a compact structure, reasonable design, and convenient operation. It can clamp and fix processed parts, and the rubber pad effectively prevents the processed parts from slipping, ensuring the stability of welding quality and facilitating user operation.
[0004] However, this electric vehicle bracket welding clamping tool still has the following defects:
[0005] 1. Heat-affected zone during welding can cause deformation due to low fixing precision, which in turn leads to inconsistent weld formation, affecting the uniformity of the folding bike. Both shrinkage and expansion during welding can cause defects such as porosity and cracks, seriously affecting the structural strength and service life of the bracket.
[0006] 2. In addition, the folding frame uses a two-section frame with concave and convex shapes on the sides for easy storage, which makes it easy to take out when folded. However, the concave frame end is not stable enough when fixed. Summary of the Invention
[0007] The purpose of this invention is to provide a welding device for the production of aircraft folding vehicle brackets, so as to solve the problems mentioned in the background art.
[0008] The technical solution of the present invention is: a welding equipment for producing aircraft folding car brackets, comprising a processing table and a folding car bracket, wherein a fixing clamp assembly is provided at the top of the processing table and the fixing clamp assembly fixes the folding car bracket, a support side frame is installed at the end of the top of the processing table away from the fixing clamp assembly, and a welding assembly is installed on one side of the support side frame, wherein the welding assembly welds the folding car bracket.
[0009] Furthermore, the fixed fixture assembly includes a fixed bracket, the bottom end of which is fixedly connected to the processing table surface, and a fixture brake is installed on one side of the fixed bracket, with a special-shaped fixture pressure plate installed at the output end of the fixture brake.
[0010] Furthermore, the fixed bracket, clamp brake, and irregular clamp pressure plate are provided in three sets, and are distributed in a ring around one side of the interior of the folding bicycle single bracket. The irregular clamp pressure plate and the fixed bracket press together to clamp the edges of the groove on both sides of the folding bicycle single bracket.
[0011] Furthermore, the welding assembly includes a support base, which is mounted on the top of the processing table. A support rod is mounted on one end of the support base near the single bracket of the folding vehicle. A second motor is mounted on the top of the support base, and an I-beam bracket is mounted on the output end of the second motor.
[0012] Furthermore, a shaping upper pressing mold is installed at the bottom end of the I-beam bracket, a fixed support plate is installed at the bottom end of the support rod, and a shaping lower pressing mold that cooperates with the shaping upper pressing mold is installed at the top end of the fixed support plate.
[0013] Furthermore, the shaping and pressing mold has a recessed tray shape with a triangular notch at the edge, and the end of the shaping and pressing mold near the single bracket of the folding vehicle has a through triangular notch.
[0014] Furthermore, the welding assembly also includes a first motor, and a T-shaped reversing drive is installed at the output end of the first motor. A transmission screw is installed at one end of the T-shaped reversing drive, and the T-shaped reversing drive drives the transmission screw to move up and down. A connecting frame is installed at the top end of the transmission screw, and limit screws are connected to both sides of the connecting frame.
[0015] Furthermore, the bottom end of the limiting screw is connected to a preset hole at one end of the support base, and the bottom end of the limiting screw is connected to the I-beam bracket, and the bottom end of the limiting screw is connected to the fixed support plate.
[0016] This invention provides an improved welding equipment for the production of aircraft folding vehicle brackets, which has the following improvements and advantages compared with the prior art:
[0017] Firstly, the welding components facilitate a closer fit to the folding frame during welding, preventing slippage. The upper and lower shaping molds are welding molds that fit together, and their internal triangular grooves conform to the recesses of the frame. This not only improves welding stability but also reduces thermal deformation of the components during welding by pressing down on them, thus improving the precision of the weld point fixation. Press welding also improves the consistency of weld formation, avoiding porosity and cracks caused by shrinkage and expansion during welding, thereby improving the uniformity of the finished folding bike and reducing defects.
[0018] Secondly, the single frame of the folding bike is the recessed side of the frame, which engages with the solid columnar frame for easy handling when folded. A fixing clamp assembly assists in securing the recessed frame end, improving the stability of the frame during welding. The fixing clamp assembly has three sets distributed opposite to the welding assembly on the single frame of the folding bike. A support side frame is provided on one side of the welding assembly to support the frame on that side. The working principle of the fixing clamp assembly is to place the fixing bracket at the bottom of the single frame of the folding bike, then activate the clamp brake to press down the irregular clamp pressure plate. The two sides of the irregular clamp pressure plate press against the fixing bracket. The pressing point between the fixing bracket and the irregular clamp pressure plate is at the edges of the recessed side of the single frame of the folding bike. The advantage of the fixing clamp assembly is that it does not crush the single frame of the folding bike while fixing it. Attached Figure Description

[0032] The following will be combined with the appendix Figures 1 to 11 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0033] This invention provides an improved welding equipment for producing aircraft folding bicycle brackets, comprising a processing table 1 and a single folding bicycle bracket 2. A fixing clamp assembly 3 is provided at the top of the processing table 1, and the fixing clamp assembly 3 fixes the single folding bicycle bracket 2. The fixing clamp assembly 3 includes a fixing bracket 301, the bottom end of which is fixedly connected to the processing table 1. A clamp brake 302 is installed on one side of the fixing bracket 301, and a non-standard clamping pressure plate 303 is installed at the output end of the clamp brake 302, thus placing the fixing bracket 301 on the bottom of the single folding bicycle bracket 2. Then, the clamp brake 302 is activated to press down the irregular clamp pressure plate 303. The fixed bracket 301, clamp brake 302 and irregular clamp pressure plate 303 are provided in three sets and are distributed in a ring on one side of the interior of the folding bicycle single bracket 2. The fixed clamp assembly 3 assists in fixing the recessed frame end, improving the stability of the frame being fixed during welding. The irregular clamp pressure plate 303 and the fixed bracket 301 press and clamp the edges of the groove on both sides of the folding bicycle single bracket 2. The advantage of the fixed clamp assembly 3 is that it will not crush the folding bicycle single bracket 2 while fixing it.
[0034] A support side frame 5 is installed at the top end of the processing table 1 away from the fixed clamp assembly 3. A support side frame 5 is also provided on one side of the welding assembly 4 to facilitate supporting the frame on one side of the welding assembly 4. The welding assembly 4 is installed on one side of the support side frame 5. The welding assembly 4 welds the folding cart single bracket 2. The welding assembly 4 includes a support base 401, which is installed at the top of the processing table 1. A support rod 410 is installed at the end of the support base 401 near the folding cart single bracket 2. A second motor 403 is installed at the top of the support base 401, and an I-beam bracket 404 is installed at the output end of the second motor 403.
[0035] A shaping upper pressing mold 405 is installed at the bottom end of the I-beam bracket 404. The second motor 403 is started to push the shaping upper pressing mold 405 at the bottom end of the I-beam bracket 404 downwards, causing the shaping upper pressing mold 405 and the shaping lower pressing mold 406 to press together. A fixing plate 411 is installed at the bottom end of the support rod 410. The fixing plate 411 is fixed to one end of the support base 401 by the support rod 410, and a shaping lower pressing mold 406 that cooperates with the shaping upper pressing mold 405 is installed at the top end of the fixing plate 411. The folding bike single bracket 2 is placed on top of the shaping lower pressing mold 406. The shaping and pressing mold 406 is designed to support the bottom end of the folding bicycle single frame 2. The shaping and pressing mold 406 has a recessed tray shape with triangular notches at its edges for heat dissipation. A through triangular notch is located at one end of the shaping and pressing mold 406 near the folding bicycle single frame 2 to facilitate the discharge of molten metal and debris overflowing from the welding joint. The welding assembly 4 also includes a first motor 402, and a T-shaped reversing drive 408 is installed at the output end of the first motor 402. A transmission screw 412 is installed at one end of the transmission device 408, and the T-shaped reversing transmission device 408 drives the transmission screw 412 to move up and down. The starting motor 402 drives the transmission screw 412 to move up and down via the T-shaped reversing transmission device 408. A connecting frame 409 is installed at the top of the transmission screw 412, thereby driving the connecting frame 409 to move up and down. The T-shaped reversing transmission device 408 drives the connecting frame 409 to move up and down through threaded and gear transmission. This is an existing transmission component. Limiting screws 407 are connected to both sides of the connecting frame 409. The bottom end of the limiting screw 407 and the support... A pre-set hole at one end of the base 401 is used for through connection. When the connecting frame 409 moves upward, it will drive the limiting screws 407 on both sides to move upward, making it easy to pull out the limiting screws 407, thereby replacing the upper shaping mold 405 and the lower shaping mold 406. The bottom end of the limiting screw 407 is connected through to the I-beam bracket 404, and the bottom end of the limiting screw 407 is connected through to the fixed support plate 411. The function of the limiting screw 407 is to limit the upper shaping mold 405 and the lower shaping mold 406 to be on the same horizontal line, so as to prevent the upper shaping mold 405 and the lower shaping mold 406 from being misaligned when pressed.
[0036] The welding component 4 facilitates a closer fit to the folding frame during welding, preventing slippage. The upper and lower shaping molds 405 and 406 are welding molds that fit together, and their interiors have triangular grooves that conform to the recesses of the frame. This not only improves the stability of the welding but also reduces the thermal reaction deformation of the device by pressing down on it during welding, thus improving the precision of the weld point fixation. Press welding also improves the consistency of the weld formation, avoids porosity and cracks caused by shrinkage and expansion during welding, and improves the uniformity of the finished folding bike, reducing defects.
[0037] Working principle: First, the welding component 4 makes it easier to fit the folding frame of the bicycle more closely during welding, preventing slippage. The upper shaping mold 405 and the lower shaping mold 406 are welding molds that fit together, and their interiors have triangular grooves that fit the recesses of the frame. This not only improves the stability of welding, but also reduces the thermal reaction deformation of the device by pressing down on it during welding, improving the precision of the weld point fixation. Press welding also improves the consistency of weld formation, avoids porosity and cracks caused by shrinkage and expansion during welding, and improves the uniformity of the finished folding bicycle and reduces defects.
[0038] Then, the second motor 403 is started to push the upper molding die 405 installed at the bottom of the I-beam bracket 404 downward, so that the upper molding die 405 and the lower molding die 406 are pressed together, and the folding bike single bracket 2 is placed on the top of the lower molding die 406, so that the lower molding die 406 can support the bottom of the folding bike single bracket 2. The lower molding die 406 has a triangular notch at its edge to facilitate heat dissipation. The through triangular notch near the end of the folding bike single bracket 2 facilitates the discharge of molten metal and debris overflowing from the welding joint. The fixed support plate 411 is fixed to one end of the support base 401 by the support rod 410. The function of the limiting screw 407 is to limit The upper and lower molding die 405 and the lower molding die 406 are aligned on the same horizontal line to prevent misalignment during pressing. The first motor 402 is started and drives the transmission screw 412 to move up and down through the T-shaped reversing drive 408, which in turn drives the connecting frame 409 to move up and down. The T-shaped reversing drive 408 drives the connecting frame 409 to move up and down through thread and gear transmission. It is an existing transmission component. When the connecting frame 409 moves up, it will drive the limit screws 407 on both sides to move up, making it easy to pull out the limit screws 407 and replace the upper and lower molding die 405 and the lower molding die 406.
[0039] Finally, the fixing clamp assembly 3 is used to assist in fixing the recessed frame end, improving the stability of the frame during welding. The fixing clamp assembly 3 has three sets distributed in the opposite direction to the welding assembly 4 on the folding bicycle single bracket 2. A support side frame 5 is provided on one side of the welding assembly 4 to facilitate lifting the frame on one side of the welding assembly 4. The working principle of the fixing clamp assembly 3 is to place the fixing bracket 301 at the bottom end of the folding bicycle single bracket 2, and then activate the clamp brake 302 to press down the irregular clamp pressure plate 303. The two sides of the irregular clamp pressure plate 303 press against the fixing bracket 301. The pressing point of the fixing bracket 301 and the irregular clamp pressure plate 303 is at the edge of the groove on both sides of the folding bicycle single bracket 2. The advantage of the fixing clamp assembly 3 is that it will not crush the folding bicycle single bracket 2 while fixing it.
