Description

Technical Field

[0001] The utility model relates to the technical field of vehicle component processing, in particular to a small axle component welding platform. Background Art

[0002] The vehicle axle is connected to the frame through a suspension, and wheels are installed at both ends. The function of the axle is to bear the load of the vehicle and maintain the normal driving of the vehicle on the road. When processing the axle, there are multiple welding points on the axle that need to be welded to other parts, and the shapes and sizes of the parts at each welding point are different. The traditional welding process usually uses manual welding. The disadvantages of manual welding are low welding efficiency and the problem of leaking welding.

[0003] The existing axle small parts welding station includes a frame and a welding gun. The frame is provided with a clamping and rotating mechanism. The clamping and rotating mechanism includes two clamping and rotating units. The two clamping and rotating units are respectively arranged on opposite sides of the frame. The axle is located between the two clamping and rotating units. The axle is clamped by the clamping and rotating units, and can drive the axle to rotate. The parts are welded on the axle by the welding gun. The disadvantage of this technical solution is that when welding parts, it is necessary to manually place the parts at a pre-set position on the axle for welding, which makes the welding efficiency low. At the same time, the welding position of the parts is prone to deviation. Utility Model Content

[0004] The utility model aims to provide a small-part welding platform for a vehicle axle, which can improve welding efficiency and positioning accuracy of parts and components and prevent leakage welding from occurring.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a small-part welding table for axle, including a mobile positioning mechanism and a placing mechanism, the mobile positioning mechanism includes a positioning unit and a mobile unit, the positioning unit includes a No. 1 mounting platform, a clamping rotating part is fixedly connected to the No. 1 mounting platform, a tightening part is slidably arranged on the No. 1 mounting platform, the clamping rotating part and the tightening part are arranged opposite to each other, the clamping rotating part is used to clamp the axle and drive the axle to rotate, the tightening part is used to tighten the axle, the mobile unit can drive the No. 1 mounting platform to move horizontally, and the placing mechanism includes a support frame, a plurality of placing units are detachably connected to the support frame, the placing unit is used to clamp parts and can place parts on the axle.

[0006] The beneficial effects of this solution are as follows: when welding parts on the axle, first install the axle between the clamping rotating part and the tightening part, and then weld the parts on the axle in turn. Specifically, first drive the axle to rotate by the clamping rotating part, rotate the axle to a preset position, and then move the No. 1 mounting platform to the preset position by the moving unit, and then place the parts on the axle by the placing unit, and press the parts by the placing unit, and weld the parts to the axle with the help of a welding gun. After welding is completed, remove the placing unit and the welding gun, and then weld the next part in turn. When all parts are welded, remove the axle from the clamping rotating part and the tightening part.

[0007] Due to the setting of the mobile positioning mechanism, the technical solution can perform welding by matching several fixed-position placement units through the movement and rotation of the axle. During the welding process, there is no need to adjust the position and welding angle of the welding gun, so that programming modifications of the welding gun are reduced.

[0008] Compared with the prior art, this technical solution, through the cooperation between the component placement unit and the mobile positioning mechanism, during the welding process, the component placement unit can accurately place the components at the welding position and can press the components, thereby improving the positioning accuracy of the components. At the same time, it can realize the CNC welding of components, improve welding efficiency, and prevent the occurrence of welding leaks.

[0009] Since a plurality of placement units are detachably connected to the support frame, the placement units are used to clamp components and place the components on the axle. Therefore, different components can be clamped on each placement unit, and the welding of different components can be achieved by matching the rotation and movement of the axle with the placement units.

[0010] Since the tightening part of the technical solution is slidably arranged on the No. 1 mounting platform, it is convenient to flexibly adjust the position of the tightening part, and it is suitable for welding parts on axles of different models.

[0011] Furthermore, a support portion is provided on the No. 1 mounting platform, and the support portion is located between the clamping rotating portion and the tightening portion, and the support portion is used to provide support for the axle.

[0012] The beneficial effect of this solution is that due to the provision of the support part, the support part can provide support for the axle when installing and removing the axle, thereby freeing the operator's hands and facilitating the operator to operate the clamping rotating part and the tightening part.

[0013] Furthermore, the clamping rotating part includes a power member No. 1 and a driving member No. 1, a reducer is installed on the power member No. 1, a chuck is installed on the reducer, an output shaft of the driving member No. 1 is fixedly connected to the chuck, and the driving member No. 1 is used to drive the movement of the claws on the chuck.

[0014] The beneficial effects of this solution are as follows: when in use, the end of the axle can be clamped by the chuck, and the chuck can be driven to rotate by the No. 1 power member to realize the rotation of the axle, which is convenient for welding parts at different positions of the axle; due to the setting of the No. 1 driving member, it is convenient to control the chuck to clamp the axle or release the axle.

[0015] Furthermore, the tightening part includes a supporting base, which is slidably arranged on a No. 1 mounting platform, and a pneumatic tailstock is fixedly connected to an upper side surface of the supporting base, and a No. 2 driving component is provided on a side of the pneumatic tailstock away from the supporting part, and an output shaft of the No. 2 driving component is fixedly connected to a telescopic shaft of the pneumatic tailstock, and the No. 2 driving component is used to drive the telescopic shaft of the pneumatic tailstock to move, and a top is fixedly connected to the telescopic shaft on a side of the pneumatic tailstock close to the supporting part.

[0016] The beneficial effect of this solution is as follows: when in use, the support base is pushed toward the side close to the axle, the support base moves on the No. 1 mounting platform, and after the support base is moved to a preset position, the No. 2 driving member is started, and the No. 2 driving member drives the telescopic shaft of the pneumatic tailstock to move, so that the top moves toward the side close to the support part, so that the top rests against the end of the axle, thereby improving the stability of the axle and ensuring the welding accuracy.

[0017] Compared with directly fixing the center to the output shaft of the second driving member, connecting the center and the output shaft of the second driving member through the pneumatic tailstock can improve the positioning accuracy, thereby reducing the welding error.

[0018] Furthermore, the supporting part includes a connecting base plate, which is slidably arranged on the No. 1 mounting platform, and the No. 3 driving member is fixedly connected to the upper side of the connecting base plate, and the supporting plate is fixedly connected to the output shaft of the No. 3 driving member.

[0019] The beneficial effects of this solution are: due to the setting of the third drive member, this technical solution can flexibly adjust the height of the support plate, so that the support plate and the axle can fit better, providing stable support for the axle.

[0020] In this technical solution, since the connecting bottom plate is slidably arranged on the No. 1 mounting platform, it is convenient to flexibly adjust the position of the supporting part and to support the vehicle axle.

[0021] Further, the mobile unit has a No. 2 mounting platform, and the No. 1 mounting platform is slidably arranged on the No. 2 mounting platform. A lead screw subassembly is installed on the No. 2 mounting platform, and the lead screw subassembly is used to drive the No. 1 mounting platform to slide on the No. 2 mounting platform.

[0022] The beneficial effect of this solution is that when in use, the screw subassembly can be used to drive the No. 1 mounting platform to slide on the No. 2 mounting platform, thereby realizing the horizontal movement of the axle, which can be matched with the placement unit provided by this technical solution, and is convenient for welding components at different positions of the axle.

[0023] Furthermore, each placement unit includes four driving members and a connecting plate, the connecting plate is in an inverted L-shape, the connecting plate includes a horizontal portion and a vertical portion connected in sequence, the horizontal portion is fixedly connected to a fixed block, the four driving members are fixedly connected to the vertical portion, a swing rod is hinged on the output shaft of the four driving members, the swing rod is hinged on the upper side of the connecting plate, and a connecting block is hinged on the free end of the swing rod, a clamping block is detachably connected to the connecting block, and a plurality of magnets are fixedly connected to the clamping block.

[0024] The beneficial effects of this solution are as follows: when in use, the component placement unit is installed on the support frame through the fixing block, and since the swing arm is respectively hinged to the output shaft and the connecting plate of the No. 4 driving member, when the components are placed on the axle, the No. 4 driving member is started, and the output shaft of the No. 4 driving member is extended, driving the free end of the swing arm to move to the side close to the axle, and the components on the clamping block are placed on the axle and welded. After the welding is completed, the output shaft of the No. 4 driving member is contracted, driving the clamping block to move to the side away from the axle, and the clamping block is separated from the components, and the welding of the components can be completed.

[0025] Compared with a connection block fixedly connected to the free end of the swing arm, a connection block hinged to the free end of the swing arm facilitates flexible adjustment of the angle of the component when placing the component on the axle, so that the component fits better on the axle and the welding quality is improved.

[0026] Since the clamping block and the connecting block are detachably connected, it is convenient to replace different clamping blocks during use to meet the welding requirements of different types of axles.

[0027] Since the clamping block is fixedly connected with a magnet, it is convenient to adsorb the components and place the components on the axle. At the same time, after welding is completed, it is convenient to separate the components from the clamping block.

[0028] Furthermore, a strip-shaped hole is provided on the fixing block.

[0029] The beneficial effect of this solution is that since the fixed block is provided with a strip hole, it is convenient to adjust the installation position of the placement unit.

[0030] Furthermore, a positioning plate is fixedly connected to the No. 1 mounting platform, and the positioning plate is located below the supporting base and the connecting bottom plate. A number of No. 1 positioning holes are opened on the positioning plate, and No. 2 positioning holes are provided on the supporting base and the connecting bottom plate.

[0031] The beneficial effect of this solution is that when the support part and the tightening part slide to a preset position, the support base and the connecting bottom plate can be fixed to the positioning plate by means of a latch, thereby improving the stability of the support part and the tightening part.

[0059] Step 6: When you need to weld the next component, repeat steps 4 and 5;

[0060] Step 7: When all the parts are welded, the No. 3 driving member 19 drives the support plate 20 to move to the side close to the axle 11, so that the support plate 20 contacts the bottom of the axle 11, and provides support for the axle 11 during the unloading process; then the No. 2 driving member 13 drives the top 16 to move to the side away from the axle 11, and releases the constraint of the top 16 on the axle 11, and then the No. 1 driving member 7 drives the chuck 10, so that the chuck 10 loosens the axle 11 and removes the welded axle 11.
