[0003] The above-mentioned existing welding method generally involves manually pinching the two free ends of the annular structure, then splicing and aligning the two free ends, and then welding the spliced ​​parts with a handheld welding gun until the spliced ​​parts are welded and fixed; as can be seen from the above, the welding operation consumes a lot of manpower, and the welding efficiency almost entirely depends on the operating speed of the operator. If batch welding operations are required, then as the operation time increases, the operator's work efficiency is bound to gradually decline due to fatigue, thereby causing the welding efficiency to decline. Summary of the invention

[0004] In order to improve the operating efficiency of welding operations in the prior art and reduce manpower consumption, the present application provides a convenient semi-automatic welding machine.

[0007] By adopting the above technical solution, the object to be welded is clamped by the clamping assembly, and there is no need to manually position the welded part of the object to be welded all the time. The welded part is driven to move by the sliding assembly, and there is no need to manually hold the welded part to move. On the one hand, manpower consumption is reduced, and on the other hand, welding errors caused by manual welding (such as missing the welded part) are avoided, so that automatic and precise welding is achieved and welding efficiency is improved.

[0008] Preferably, the clamping assembly includes a guide column, a limit plate, a spacing adjustment piece and a blanking piece, the guide column and the limit plate are both arranged on the frame, a clamping space is reserved between the guide column and the limit plate for inserting the welding part of the object to be welded, the spacing adjustment piece is used to control the movement of the limit plate away from or close to the guide column, and adjust the size of the clamping space, the side wall of the limit plate near the welding part is provided with a clearance notch for inserting the welding part, and the blanking piece is used to drive the guide column to move so that the object to be welded is out of the clamping space.

[0009] By adopting the above technical scheme, the welding part of the object to be welded is inserted into the clamping space, and the size of the clamping space is adjusted by the spacing adjustment piece according to the size specifications of the object to be welded, so that the welding part of the object to be welded is clamped and fixed by the guide column and the limit plate, and then the welding part is passed through the clearance gap and toward the welding part, and then the welding part is started to realize the welding operation on the welding part. After the welding operation is completed, the guide column is driven to move by the blanking piece, so that the object to be welded is separated from the clamping space, that is, separated from the clamping of the guide column and the limit plate, so as to realize blanking.

[0010] Preferably, the blanking part includes a magnetic part and a magnetic attraction part that are magnetically fixed. A through hole is opened on the top of the frame for the guide column to pass through and insert. The magnetic part is arranged on the inner wall of the through hole, and the magnetic attraction part is arranged on the peripheral wall of the guide column. The guide column is slidably connected in the through hole along its height direction.

[0011] By adopting the above technical solution, after welding is completed, the guide column is manually lifted to open the clamping space. At this time, the object to be welded can be taken out from the clamping space below the guide column to realize unloading. The magnetic part and the adsorption part are provided to fix the position of the guide column relative to the frame after the guide column is moved down and reset, so as to realize stable clamping of the object to be welded by the guide column and the limit plate.

[0012] Preferably, the blanking member includes a pull rope symmetrically arranged at the bottom of the guide column, a winding rod arranged one-to-one with the pull rope, a main gear rotatably connected to the inner wall of the through hole, a first motor arranged on the frame, a circular plate rotatably connected to the frame, and a first bevel gear and a second bevel gear;

[0013] The main gear, the first bevel gear, the second bevel gear and the winding rod are arranged in a one-to-one correspondence; the first bevel gear is sleeved on the corresponding winding rod, the second bevel gear is meshed with the first bevel gear, and the second bevel gear is coaxially rotatable with the corresponding main gear and is connected to the inner wall of the through hole, and the circumferential wall of the circular plate is provided with a tooth groove meshing with the main gear; the end of the pull rope away from the guide column is wound around the corresponding winding rod, and the first motor driving end is connected to one of the ends of the winding rod to drive the winding rod to rotate.

At this time, the guide column moves upward under the pull of the pull rope, thereby opening the clamping space.

[0015] Preferably, the guide column is hollow inside, and a first adsorption port is provided on the side wall of the guide column near the clearance notch along the height direction of the guide column. The clamping assembly also includes a plurality of adsorption tubes arranged inside the guide column, a valve arranged on each adsorption tube, and an adsorption component connected to all adsorption tubes; the adsorption tubes are arranged along the height direction of the guide column, the tube mouths of the adsorption tubes are arranged at the first adsorption port, and the tube wall of the tube mouth of the adsorption tube is flush with the peripheral wall of the guide column.

[0016] By adopting the above technical scheme, a specified number of valves are opened according to the length of the part to be welded, and then the adsorption part is started to form a negative pressure at the mouth of the adsorption tube. When the part to be welded of the object to be welded is inserted in the clamping space, the object to be welded can be adsorbed by the adsorption tube to achieve preliminary fixation of the insertion position of the object to be welded, and then the object to be welded is clamped by the limit plate and the spacing adjustment part.

[0017] Preferably, a fixing frame is further provided inside the guide column, the adsorption tube and the adsorption member are provided on the fixing frame, a loading rod is symmetrically provided on the bottom wall of the fixing frame, the loading rod is rotatably connected to the fixing frame around the axis of the guide column, a loading notch for inserting the loading rod is provided along the circumference of the side wall at the bottom of the guide column, a driving member for driving the loading rod to move toward or away from the clearance notch is provided inside the guide column, and a second adsorption port connected to the adsorption member is provided at the end of the loading rod.

[0018] By adopting the above technical scheme, the to-be-welded part of the object to be welded is attached to the end of the loading rod, so that the object to be welded is fixedly adsorbed by the adsorption member and the second adsorption port, and then the loading rod is driven by the driving member to rotate in the direction close to the clearance gap, so that the object to be welded is inserted into the clamping space and moved to the clearance gap as the loading rod rotates, thereby realizing automatic loading and avoiding the situation that the to-be-welded part of the object to be welded cannot be accurately assembled when the object to be welded is manually inserted into the clamping space.

[0019] Preferably, a dust-proof filter is provided on the side wall of the feeding rod close to the second adsorption port and on the port of each adsorption tube.

[0020] By adopting the above technical solution, the setting of the dust filter can play a dust-proof role for the second adsorption port and the adsorption tube port, thereby preventing dust and impurities in the external environment from blocking the adsorption tube or the second adsorption port during the adsorption process, thereby affecting the subsequent adsorption effect.

[0021] Preferably, the driving member includes a driving gear, a ring plate, a first tooth block, and a second motor. The number of the feeding rods is 2, and the ring plate, the feeding rod, and the first tooth block correspond to each other one by one, and the feeding rod is connected to the corresponding ring plate; the first tooth block is arranged on the peripheral wall of the ring plate along the circumference of the ring plate, the driving gear is located between the two ring plates, and the driving gear is meshed with the first tooth blocks on the two ring plates. The driving end of the second motor is inserted in the center of the driving gear to drive the driving gear to rotate.

[0022] By adopting the above technical scheme, when loading, the to-be-welded part of the object to be welded is attached to the second adsorption port at the end of the loading rod, so that the to-be-welded part of the object to be welded is fixedly adsorbed to the end of the loading rod through the adsorption piece, and then the second motor is started to drive the driving gear to rotate. Since the two ring plates are located on both sides of the driving gear and are both meshed with the driving gear, the two ring plates will rotate under the drive of the rotating driving gear and the rotation directions are opposite. Correspondingly, since the loading rod is connected to the corresponding ring plate, the rotating ring plate will drive the corresponding loading rod to move in the direction of approaching or moving away from each other. When the two loading rods move in the direction of approaching each other, the loading rod can drive the to-be-welded object adsorbed and fixed at its end to be inserted into the clamping space, thereby realizing automatic loading.

[0023] Preferably, each of the feeding rods is rotatably connected with a linkage rod, a connecting tube is sleeved on the linkage rod, one end of the connecting tube is connected to the adsorption piece, and the other end passes through the end of the feeding rod, and the second adsorption port is located at the end of the connecting tube away from the adsorption piece; a docking plate is provided at the end of the feeding rod; and a moving component is also included, which is used to drive the docking plate to retract or extend into the feeding rod, and the moving component is also used to drive the connecting tube to rotate around the linkage rod, so that the connecting tube moves toward or away from the docking plate.

[0024] By adopting the above technical solution, when the object to be welded is a steel strip and the parts to be welded are the free ends of the steel strip, the operator adsorbs the free ends of the steel strip to the ends of the connecting pipe respectively. At this time, the setting of the docking plate is used to assist the operator in calibrating the adsorption position. After the end of the steel strip is inserted into the clamping space by rotating the loading rod, the docking plate is slid into the loading rod through the moving component. At this time, the two free ends of the steel strip have not been completely spliced ​​together. Therefore, the two connecting pipes are driven by the moving component to move in a direction close to each other, so that the two ends of the steel strip are spliced ​​together, which is convenient for subsequent welding of the spliced ​​position.

[0025] Preferably, the moving assembly includes a rotating rod rotatably connected to each feeding rod, a connecting rope wound on each linkage rod, a reset member connected to each docking plate, a docking gear sleeved on each rotating rod, a second gear block arranged on each ring plate, and a bevel gear set arranged between the linkage rod and the rotating rod;

[0026] The bevel gear set is used to drive the linkage rod to rotate when the rotating rod rotates. The docking gear on each rotating rod is used to engage with the second tooth block on the ring plate corresponding to the other rotating rod. The connecting rope, connecting plate, reset member and rotating rod are arranged in a one-to-one correspondence. One end of the connecting rope away from the linkage rod is connected to the corresponding docking plate, and the reset member is used to drive the connecting plate to extend the loading rod.

[0027] By adopting the above technical solution, since each feeding rod rotates in opposite directions to the other feeding rod, when the two rotating rods gradually approach each other, the docking gear on one of the feeding rods just meshes with the second tooth block corresponding to the other feeding rod. At this time, the docking gear will rotate driven by the second tooth block, thereby causing the rotating rod to rotate. At this time, the bevel gear set drives the linkage rod to rotate when the rotating rod rotates. The linkage rod winds the connecting rope during the rotation process, and the connecting rope pulls the docking plate to completely pull the docking plate into the feeding rod. At the same time, the linkage rod during the rotation process drives the connecting tube to move toward the direction close to the docking plate, thereby causing the connecting tube to drive the adsorbed object to be welded (such as a steel strip) to move toward the direction close to the docking plate, thereby realizing the splicing of the two ends of the steel strip.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The object to be welded (such as steel strip) is clamped by the clamping assembly, and there is no need to manually fix the welded part of the object at all times. The welded part is driven to move by the sliding assembly, and there is no need to manually hold the welded part to move. On the one hand, it reduces manpower consumption, and on the other hand, it avoids welding errors caused by manual welding (such as missing the welded part), realizes automatic and precise welding, and improves welding efficiency;

[0030] 2. Fit the part to be welded of the object to be welded to the end of the loading rod, so as to fix and adsorb the object to be welded through the adsorption member and the second adsorption port, and then drive the loading rod to rotate in the direction close to the clearance gap through the driving member, so that the object to be welded is inserted into the clamping space and moved to the clearance gap as the loading rod rotates, thereby realizing automatic loading and avoiding the situation that the part to be welded of the object to be welded cannot be accurately assembled when the object to be welded is manually inserted into the clamping space.
