Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding processing platform, more specifically, relates to a welding processing platform for liquid path box. BACKGROUND

[0002] In the field of liquid path box accessory welding, traditional welding equipment and process have many problems to be solved, which seriously restrict the welding efficiency, welding quality and adaptability to different shape liquid path box accessories.

[0003] Single fixing method and lack of flexibility

[0004] When fixing the liquid path box accessory, the traditional welding equipment usually adopts a simple and fixed clamp, which is difficult to adjust in real time according to the complex and diverse shape of the liquid path box accessory. The liquid path box accessory is generally composed of multiple structures with different shapes. The traditional clamp cannot realize multi-module control, and it is difficult to accurately fix different positions and shapes. During the welding process, the liquid path box accessory is prone to displacement, which affects the welding quality and cannot fully exert the efficiency of the welding equipment, greatly reducing the welding efficiency.

[0005] Difficulty in docking and height adjustment

[0006] For the butt welding of special-shaped liquid path box accessories, the traditional equipment lacks effective horizontal and height adjustment mechanism. Before welding, it is difficult to accurately horizontally butt joint two liquid path box accessories, and after butt joint, it is difficult to flexibly adjust the diagonal height of the liquid path box accessory, which increases the difficulty of diagonal welding and seriously affects the welding quality and success rate of special-shaped liquid path box accessories, which cannot meet the high precision requirements of modern industry for welding of complex shape liquid path box accessories.

[0007] Inconvenient detail welding

[0008] The traditional welding equipment has defects when welding the detail part of the liquid path box accessory. Due to the lack of structure for fine adjustment of the local part of the accessory, the operator is difficult to adjust the accessory to the appropriate welding position, which leads to poor welding quality of the detail part, easy to appear virtual welding, missing welding and other problems, affecting the overall performance and service life of the liquid path box.

[0009] Insufficient auxiliary fixation

[0010] During the welding process, the traditional equipment has limited auxiliary fixation measures for the liquid path box accessory. After the accessory is preliminarily fixed, there is a lack of further auxiliary fixation structure to prevent the accessory from moving during the welding process, especially for some parts that are prone to move under stress during welding, which cannot provide reliable fixation, thereby affecting the stability and quality of welding.

[0011] Complex operation and low efficiency

[0012] The operation of the conventional welding equipment is generally complex, and there is lack of coordination between various adjusting and fixing functions. For example, when performing fixing, adjusting position, and auxiliary fixing operations, the operator needs to perform tedious step-by-step operations, which consumes a lot of time and effort, resulting in low overall welding efficiency and failing to meet the needs of large-scale production.

[0013] In summary, the existing liquid tank accessory welding technology has obvious deficiencies in fixing flexibility, docking and height adjustment, detail welding, auxiliary fixing, and operation efficiency, and cannot meet the needs of modern industry for efficient and high-quality welding of liquid tank accessories.

[0018] Preferably, a chute is arranged at the top of each drive screw, two opposite clamping sliders are installed in the chute, a third spring is fixedly installed between the two clamping sliders, an upper sliding rod is arranged at the top of each drive screw, a second spring is installed between each upper sliding rod and the top of the drive screw, a rectangular sliding rail is arranged in the inner walls of each tubular support and pipe end gripper, the rectangular sliding rail is in communication with the threaded grooves on both sides, and the upper sliding rod is located in the rectangular sliding rail, at least two positioning clamping grooves are annularly arranged in the inner wall of the lower sleeve, and at least two elastic positioning beads are movably embedded in the outer ring of each lower sleeve.

[0019] Compared with the prior art, the present application has the following advantages:

[0020] In the present application, the liquid path box fittings to be welded are placed above the welding rack, the liquid path box fittings are generally composed of multiple structures, the lower fixing table is started to drive the liquid path box fittings to move upwards, and the liquid path box fittings can also be horizontally adjusted left and right, the plurality of lower fixing tables and upper support tables on the welding rack can be modularly controlled according to the actual size of the liquid path box fittings, the liquid path box fittings at different positions on the plurality of upper support tables can be independently controlled, and the plurality of tubular supports in the upper support table can be telescoped to drive the liquid path box fittings to be controlled again, or the side wings of the pipe end gripper can be used to fix the liquid path box fittings, so that the liquid path box fittings can be controlled by multiple modules, the fixing can be adjusted in real time according to the shape of the liquid path box fittings, and therefore the welding efficiency can be improved.

[0021] In the application, the second driving assembly drives the two connecting rods to slide up or down in the sliding support frame. When moving horizontally, the two first driving assemblies are started to drive the sliding support frame to move horizontally. The movement of the sliding support frame drives the overall horizontal movement of the lower fixing table. Before welding the liquid path box fittings, the horizontal movement of the multiple lower fixing tables can drive the horizontal butt joint of the two liquid path box fittings. Then the upward and downward movement of the multiple lower fixing tables in modules can realize the diagonal height adjustment of the liquid path box fittings, improve the diagonal welding capacity, realize the butt joint of the special-shaped liquid path box fittings, and the two upper connecting rods and the lower connecting rod below the lower fixing table can assist the upward and downward extension of the upper connecting rod, and the lower connecting rod is not fixedly connected with the welding rack, and can move with the lower fixing table.

[0022] In the application, after the preliminary fixation of the liquid path box fittings on the lower fixing table and the upper support table is completed, the driving motor is started. The driving motor is started to drive the tubular support to move upward. The upward movement of the tubular support can drive the partial position of the liquid path box fittings to move upward, so that the welding of the detailed part of the liquid path box fittings can be realized. The end of the liquid path box fittings can be blocked upward by the multiple tubular supports to prevent displacement of the liquid path box fittings.

[0023] In the application, the multiple elastic positioning beads of the lower sleeve outer ring are bounced into the positioning ball grooves of the tubular sliding groove. At this time, the lower sleeve is subjected to a certain resistance of the elastic positioning beads. Meanwhile, the clamping sliding blocks at both ends of the driving screw are shot into the positioning clamping grooves by the third spring. At this time, the continuous rotation of the driving screw drives the tubular support as a whole through the clamping sliding blocks. The tubular support drives the rotation of the lower sleeve and the pipe end clamp. After the pipe end clamp is rotated to a suitable angle, the driving screw starts to rotate reversely. Since the lower sleeve is subjected to the resistance of the elastic positioning beads, and the clamping sliding blocks are retracted into the sliding groove of the driving screw when the clamping sliding blocks rotate reversely driven by the driving screw, the second spring is in a stretched state. The second spring pulls the upper sliding rod downward, and simultaneously pulls the driving screw downward. The threaded groove in the driving screw is in contact with the outside of the driving screw. At this time, the continuous rotation of the driving screw drives the downward movement of the tubular support. The pipe end clamp moves downward above the liquid path box fittings. The side rod of the pipe end clamp can press and fix the side edge of the liquid path box fittings, so as to play an auxiliary fixing role. The driving screw can rotate the pipe end clamp in the same way as the tubular sliding groove and the arc-shaped guide groove, so as to be retracted into the upper support table.
