Description

Technical Field

[0001] The utility model relates to a production device for stud welding of an air box main body in the production and manufacturing of ring main units and related fields. Background Art

[0002] The air box of the ring main unit is mainly connected to the vertical cabinet sheet metal, the operating mechanism, and the internal switch by M8 studs. Therefore, it is necessary to install and weld these studs on both the front and back sides of the air box main body panel for subsequent connection with the vertical cabinet sheet metal, the operating mechanism, and the internal switch. In the prior art, usually an air box main body panel is placed on the ground. After the operator welds one side, the worker flips it over and then welds the other side, which is time-consuming and laborious. Content of the Utility Model

[0003] The purpose of the utility model is to provide a production device for stud welding of an air box main body of a ring main unit, which can weld multiple air box main body panels at one time and automatically flip, with higher efficiency.

[0004] To achieve the above purpose, the utility model provides a production device for stud welding of an air box main body of a ring main unit, including a power mechanism, which is equipped with a flipping mechanism, and the flipping mechanism is equipped with a lateral limiting structure and a feeding mechanism.

[0005] Compared with the prior art, the beneficial effect of the utility model lies in that multiple air box main body panels are hoisted and placed into the flipping mechanism. Through the limiting structure, the air box is limited to move within a small range in the lateral direction to ensure the overall stability of the device during the flipping process. The operator first welds the studs on the inner and outer sides of the vertical surface of the air box main body panel. After that, the flipping mechanism is driven by the power mechanism to flip 90 degrees, and the part of the panel that was originally at a high position is flipped to the vertical surface, so as to facilitate welding the studs on these parts. Then it rotates 90 degrees again, cancels the limitation of the limiting structure, takes down the welded air box main body panel from the flipping mechanism, and then proceeds with the next round of welding. It can weld multiple air box main body panels at one time and automatically flip, with higher efficiency.

[0006] As a further improvement of the utility model, the power mechanism includes a transmission main shaft. Both ends of the transmission main shaft are provided with main transmission frames. The transmission main shaft is also equipped with an intermediate transmission frame, which is arranged between the main transmission frames. Installation plates cooperating with the flipping mechanism are sleeved at positions near the main transmission frames at both ends of the transmission main shaft. A transmission motor is arranged on the outer side of one of the main transmission frames. The transmission motor is connected to a gearbox, and the gearbox is connected to the transmission main shaft.

[0007] In this way, the driving motor rotates, drives the driving main shaft to rotate through the gearbox, and both ends of the turnover mechanism are fixedly connected to the mounting plate. The mounting plate is sleeved on the driving main shaft. When the driving main shaft rotates, it will drive the mounting plate to rotate, thereby driving the turnover mechanism to rotate.

[0008] As a further improvement of the present utility model, the turnover mechanism includes a feeding frame and a discharging frame. The feeding frame and the discharging frame are respectively installed on a mounting plate. A plurality of welding frames are arranged between the feeding frame and the discharging frame. A feeding area is formed between the feeding frame and the adjacent welding frame, and a discharging area is formed between the discharging frame and the adjacent welding frame.

[0009] In this way, the main panel of the air box enters the turnover mechanism from the feeding area and enters the welding area formed between the welding frames through the feeding mechanism. After the welding area is filled with materials, the main panels of the air box are separated from each other by the limiting structure. Horizontally, they can only have a little displacement within a limited range, which limits the panels from moving horizontally in a large range and also enables the panels to move horizontally in a small range, so that the screw holes on them can avoid the obstruction of the mounting frame, facilitating the installation and welding of bolts. After welding, the panels are taken out from the discharging area.

[0010] As a further improvement of the present utility model, the feeding mechanism includes a mutually matching outer smooth strip and inner smooth strip. There is a material passing gap between the outer smooth strip and the inner smooth strip. The outer smooth strip is installed on the outer mounting rod, the inner smooth strip is installed on the inner mounting rod. The outer mounting rod is connected to the inner side surface of the outer frame of the welding frame. Both ends of the inner mounting rod are respectively connected to the inner side surfaces of both ends of the feeding frame and the discharging frame. The inner mounting rod is also connected to the welding frame. The pulley of the inner smooth body extends out of the edge of the mounting plate.

[0011] In this way, the pulley of the outer smooth strip contacts the outer surface of the main panel of the air box, and the pulley of the inner smooth strip contacts the inner surface of the main panel of the air box, thereby clamping the main panel of the air box between the two. And the arrangement of the outer smooth strip and the inner smooth strip fits the shape of the main panel of the air box, so that the main panel of the air box can be inserted between the two and then pushed into the turnover mechanism. After welding, it is also convenient to push the panel out of the discharging area for convenient discharging.

[0012] As a further improvement of the present utility model, the horizontal limiting structure includes a fixed block. The fixed block is installed on an outer mounting rod located at the upper part of the outer frame of the welding frame. A hinge seat is arranged on the fixed block. The hinge seat is hinged to the limiting strip through a pin shaft. A limiting bolt is inserted through the limiting strip, and the limiting bolt matches the limiting hole opened on the fixed block.

[0013] After all the main panels of the air box are placed in the welding area formed by the welding jig, flip the limit strip, insert it between the two panels, then screw the limit bolt into the limit hole to fix the limit strip, so that the panel can only be between the two limit strips. After welding contact, unscrew the limit bolt again, and then open the limit strip so that the panel can be pushed into the discharging area for easy material taking.

[0014] As a further improvement of the present utility model, a pair of limit switches are arranged on the outer side surface of the mounting plate, and the limit switches respectively correspond to both sides of the main transmission frame.

[0015] In this way, when the mounting plate rotates 90 degrees, one limit switch senses one side surface of the mounting frame, and thus the motor automatically stops rotating. When it rotates 90 degrees in the reverse direction, the other limit switch senses the other side surface of the mounting frame, and the motor automatically stops, ensuring that the rotation angle of the flipping mechanism does not exceed 90 degrees.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below in conjunction with the accompanying drawings:

[0026] As Figure 1-8 shown, a production device for stud welding of the gas tank body of a ring main unit includes a power mechanism, which is equipped with a flipping mechanism, and the flipping mechanism is equipped with a lateral limiting structure and a feeding mechanism.

[0027] The power mechanism includes a transmission main shaft 10. At both ends of the transmission main shaft 10, there are main transmission frames 1. The transmission main shaft 10 is also equipped with an intermediate transmission frame 7, which is arranged between the main transmission frames 1. At positions near the main transmission frames 1 at both ends of the transmission main shaft 10, there are mounting plates 2 that cooperate with the flipping mechanism. On the outer side of one of the main transmission frames 1, there is a transmission motor 6, which is connected to a gearbox 11, and the gearbox 11 is connected to the transmission main shaft 10.

[0028] The flipping mechanism includes a feeding frame 5 and a discharging frame 3. The feeding frame 5 and the discharging frame 3 are respectively installed on a mounting plate 2. Between the feeding frame 5 and the discharging frame 3, there are several welding frames 4. Between the feeding frame 5 and the adjacent welding frame 4, there is a loading area, and between the discharging frame 3 and the adjacent welding frame 4, there is a unloading area.

[0029] The feeding mechanism includes an outer fluent strip 20 and an inner fluent strip 17 that match each other. There is a material passing gap between the outer fluent strip 20 and the inner fluent strip 17. The outer fluent strip 20 is installed on an outer mounting rod 18, and the inner fluent strip 17 is installed on an inner mounting rod 19. The outer mounting rod 18 is connected to the inner side of the outer frame of the welding frame 4, and both ends of the inner mounting rod 19 are respectively connected to the inner sides of both ends of the feeding frame 5 and the discharging frame 3. The inner mounting rod 19 is also connected to the welding frame 4. The pulley of the inner fluent body extends out of the edge of the mounting plate 2.

[0030] The lateral limiting structure includes a fixed block 23, which is installed on an outer mounting rod 18 at the upper part of the outer frame of the welding frame 4. There is a hinge seat 24 on the fixed block 23. The hinge seat 24 is hinged to a limiting strip 21 through a pin shaft. A limiting bolt 22 is inserted through the limiting strip 21, and the limiting bolt 22 matches the limiting hole opened on the fixed block 23. On the outer side of the mounting plate 2, there are a pair of limit switches 16, which respectively correspond to both sides of the main transmission frame 1.

[0031] In the present utility model, the flipping mechanism is divided into three parts, namely a discharging area 1312 and a feeding area 15 at both ends of the flipping mechanism, and a welding area 14 is between the discharging area 1312 and the feeding area 15.

[0032] During normal operation, lift the main panel 8 of the air box to be welded to the feeding area 15. After the main panel 8 of the air box adjusts its shape to match the position according to the distribution drop of the internal smooth strip 17, it lands on the internal smooth strip 17 in the feeding area 15. Push the main panel 8 of the air box in the reverse direction of the discharging area 1312, so that the air box body enters the welding area 14. In this way, the outer surface of the main panel 8 of the air box contacts the external smooth strip 20 in the welding area 14, and the inner surface of the main panel 8 of the air box contacts the internal smooth strip 17 in the welding area 14. Through the internal and external cooperation of the internal smooth strip 17 and the external smooth strip 20, the main panel 8 of the air box moves to the limiting structure closest to the discharging area 1312. Flip the limiting strip 21 so that the limiting strip 21 contacts one side of the main panel 8 of the air box, and screw the limiting bolt 22 on the limiting strip 21 tightly into the limiting hole on the fixing block 23, so that the main panel 8 of the air box cannot move forward continuously and is prevented from entering the discharging area 1312. Then, flip the limiting strip 21 on the other side close to the main panel 8 of the air box in the same way and fix it by screwing the limiting screw. In this way, the main panel 8 of the air box is between the two limiting strips 21, and its displacement in the horizontal direction is limited by the two limiting strips 21.

[0033] Subsequently, place the subsequent main panels 8 of the air boxes to be welded from the feeding area 15 and push them into the welding area 14, and also limit them through the corresponding limiting strips 21 until the welding area 14 is full of the main panels 8 of the air boxes to be welded. At this time, the main panels 8 of the air boxes are clamped by the internal smooth strip 17 and the external smooth strip 20 and cannot move up, down, forward or backward. The distance between adjacent limiting strips 21 is slightly larger than the width of the main panel 8 of the air box, so that the main panel 8 of the air box can move slightly left and right in the horizontal direction between adjacent limiting strips 21, which is convenient for the operator to assemble and weld the M8 studs to the main panel 8 of the air box. When the M8 studs are assembled and welded, interference with the mounting brackets in the welding area 14 is avoided.

[0034] After all the M8 studs on the inner and outer parts of the vertical surfaces of all the main panels 8 of the air boxes in the welding area 14 are assembled and welded and the sleeve pressing plate 9 is also assembled and welded in place, press the switch to control the driving motor 6 to rotate, and drive the driving main shaft 10 to rotate by the gear box 11, so as to rotate the flipping mechanism together with the mounting plate 2 by 90 degrees, so that the original horizontal plane where the main panel 8 of the air box is at a high position becomes a vertical plane after rotating 90 degrees, which is convenient for the operator to assemble and weld the M8 studs on this part. After all the welding is completed, reverse and flip 90 degrees again, open the limiting strip 21, and push the main panels of the air box from the welding area 14 to the discharging area 1312 in sequence and remove them.

[0035] In the above process, through the clamping cooperation of the internal smooth strip 17 and the external smooth strip and the limitation of the limiting strip 21, the main panel 8 of the air box in the flipping mechanism will not move greatly, and the flipping process is relatively stable.

[0036] The utility model can batch-assemble and weld the air box main body panel 8 and M8 studs with only one person, and there is no need for manual turning over, with higher production efficiency, saving time and effort. Moreover, the feeding rack, discharging rack and welding rack are made of aluminum alloy profiles, and the number of welding racks can be increased or decreased according to the actual site and production requirements for assembly, so as to form the required device, making the applicability of the device better.

[0037] The utility model is not limited to the above embodiments. Based on the disclosed technical solutions, those skilled in the art can make some substitutions and deformations to some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the utility model.
