[0002] Metal accessories in metal furniture, such as columns, mainly play the role of supporting and bearing weight. In order to facilitate the subsequent assembly of the columns and other accessories of the metal furniture, multiple connectors are generally welded to the columns by welding to facilitate subsequent connection and assembly. However, during the welding process, the existing welding facilities can only weld and fix one connector to the column at a time, and the welding process takes a long time. It is necessary to propose a solution to solve the above technical problems;

[0003] For example, in the prior art with publication number CN118060683B, the device in this scheme can limit multiple connecting parts on the column by setting multiple brackets. At this time, the T-slot seat is driven to rotate under the operation of the No. 1 servo motor, thereby driving multiple arc welding guns to perform arc displacement, so as to simultaneously perform arc welding on the column and multiple connecting parts, thereby shortening the welding time and improving the welding efficiency;

[0004] The metal column of the home is generally made of aluminum alloy. A U-shaped frame is inserted into the middle of the column and then welded to form a crossbar for hanging clothes. In the process of inserting the U-shaped frame into the middle of the column, the U-shaped frame is not limited, which makes the position of the U-shaped frame inaccurate during subsequent welding, which easily causes unstable welding and affects normal use. At the same time, after the U-shaped frame is welded, the temperature of the column surface is high, which is inconvenient to effectively cool it, thereby reducing the efficiency of unloading the column. Summary of the invention

[0013] A further technical improvement of the present invention is that: a first cylinder arranged transversely is fixedly installed on the outer shell on one side of the mounting plate, the extended end of the first cylinder is fixedly connected to the moving block, and the bottom of the extended end of the first cylinder is also fixedly connected to a connecting frame, and the bottom of the connecting frame is slidably connected to the middle part of the L-shaped frame through a second lever; by controlling the extended end of the first cylinder to extend to half the length, the second lever slides from the middle part of the L-shaped frame to a section thereof away from the first lever, and cooperates with the first lever to pull the transmission rod and the booster piston, so that the air in the pressure regulating cylinder enters the water storage tank along the connecting pipe. , increase the air pressure in the water tank, so that the clean water in the water tank is injected into the bottom of the inner wall of the column along the U-shaped tube, and the column is cooled down by the clean water entering the inner wall of the column.

During this process, the push rod drives the pressing plate to flip, and there is still a gap between one end of the pressing plate and the top of the column. ; Then control the extended end of the second cylinder to continue to extend to its longest length, so that the roller rolls from the upper side of the trapezoidal block close to the mounting sleeve to its lower part. During this process, the position of the clamping plate does not move, and the pressing plate provides pressure on the top of the column to determine the longitudinal position of the column. At this time, the position of the socket of the column will correspond to the position of the moving block. At the same time, the bottom of the column is in close contact with the rubber seat; control the extended end of the first cylinder to extend to its longest length, so that the moving block drives the U-shaped frame to insert into the socket of the column. Since the moving block cooperates with the mounting strip to guide and position the position of the U-shaped frame, the inaccurate position of the U-shaped frame during subsequent welding is avoided, which may easily cause unstable welding.

[0018] Step 1: Open the box door. At this time, the extended end of the second cylinder is at its shortest, and the roller is located on the inclined surface of the trapezoidal block. Due to the action of the second tension spring, the clamping plate is close to the inner wall of the mounting sleeve, which is convenient for inserting the column into the mounting sleeve; then the extended end of the second cylinder is controlled to extend, so that the trapezoidal block moves upward. When the roller rolls from the inclined surface of the trapezoidal block to the upper part of the side close to the mounting sleeve, the roller cooperates with the extrusion rod to drive the clamping plate to provide thrust to the side of the column, and cooperates with the inner wall of the mounting sleeve to preliminarily position the column. During this process, the push rod drives the pressing plate to flip, and there is still a gap between one end of the pressing plate and the top of the column;

[0019] Step 2: Then control the extended end of the second cylinder to continue to extend to the longest, so that the roller rolls from the upper side of the trapezoidal block close to the mounting sleeve to the lower side. During this process, the position of the clamping plate does not move, and one end of the pressing plate turns over to provide pressure on the top of the column, so that the longitudinal position of the column is determined.

[0020] Step 3: During the extension of the extended end of the second cylinder, the U-shaped frame is sleeved on the moving block, guided by the mounting strip, and then positioned in cooperation with the baffle plate, the extended end of the first cylinder is controlled to extend to half the length, the U-shaped frame has not yet contacted the socket of the column, the second lever slides from the middle of the L-shaped frame to a section away from the first lever, at this time, the first lever is cooperated to pull the transmission rod and the booster piston, so that the air in the pressure regulating cylinder enters the water storage tank along the connecting pipe, the air pressure in the water storage tank is increased, and the clean water in the water storage tank is injected into the bottom of the inner wall of the column along the U-shaped pipe, and the column is cooled by the clean water entering the inner wall of the column. Since the bottom of the column is in close contact with the rubber seat, leakage is avoided;

[0021] The U-shaped frame is then welded to the base and then retracted to the base, and the U-shaped frame is then welded to the base.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When the present invention is in use, the extended end of the second cylinder is controlled to extend so that the trapezoidal block moves upward. When the roller rolls from the inclined surface of the trapezoidal block to the upper side of the side close to the mounting sleeve, the roller cooperates with the extrusion rod to drive the clamping plate to provide thrust to the side of the column, and cooperates with the inner wall of the mounting sleeve to perform preliminary positioning of the column. During this process, the push rod drives the pressing plate to flip, and there is still a gap between one end of the pressing plate and the top of the column; then the extended end of the second cylinder is controlled to continue to extend to the longest, so that the roller rolls from the upper side of the trapezoidal block close to the mounting sleeve to the upper side of the side of the trapezoidal block At its lower part, during this process, the position of the clamping plate does not move, and the pressing plate provides pressure on the top of the column to determine the longitudinal position of the column. At this time, the position of the socket of the column will correspond to the position of the moving block. At the same time, the bottom of the column is in close contact with the rubber seat; the extended end of the first cylinder is controlled to extend to the longest, so that the moving block drives the U-shaped frame to insert into the socket of the column. Since the moving block cooperates with the mounting strip to guide and position the position of the U-shaped frame, inaccurate position of the U-shaped frame during subsequent welding is avoided, which may easily cause unstable welding.

[0024] When the present invention is in use, by controlling the extended end of the first cylinder to extend to half the length, the second lever slides from the middle of the L-shaped frame to a section thereof away from the first lever, and cooperates with the first lever to pull the transmission rod and the boosting piston, the air in the pressure regulating cylinder enters the water tank along the connecting pipe, the air pressure in the water tank is increased, and the clean water in the water tank is injected into the bottom of the inner wall of the column along the U-shaped pipe, the column is cooled by the clean water entering the inner wall of the column, and leakage is avoided because the bottom of the column is in close contact with the rubber seat; the extended end of the first cylinder is continued to be controlled to extend to the longest, the welding tool is controlled to weld the U-shaped frame, the U-shaped frame is prevented from moving by the baffle and the positioning plate, and after the welding is completed, the extended end of the first cylinder is controlled to shrink to half the length, the moving block is withdrawn from the U-shaped frame, and the clean water at the bottom of the inner wall of the column continues to cool the column.

At this time, the extended end of the second cylinder 904 is at its shortest, and the roller is located on the inclined surface of the trapezoidal block 906. Due to the action of the second tension spring, the clamping plate 903 is close to the inner wall of the installation sleeve 902, which facilitates the insertion of the column into the installation sleeve 902; Figure 5 and Figure 6 As shown, the extended end of the second cylinder 904 is controlled to extend, so that the trapezoidal block 906 moves upward. When the roller rolls from the inclined surface of the trapezoidal block 906 to the upper part of the side close to the mounting sleeve 902, the roller cooperates with the extrusion rod 905 to drive the clamping plate 903 to provide thrust to the side of the column, and cooperates with the inner wall of the mounting sleeve 902 to perform preliminary positioning of the column. During this process, the push rod 907 drives the pressing plate 901 to flip, and there is still a gap between one end of the pressing plate 901 and the top of the column.

[0049] Step 2: If Figure 5 and Figure 6 As shown, the extended end of the second cylinder 904 is controlled to continue to extend to the longest, so that the roller rolls from the upper side of the trapezoidal block 906 close to the mounting sleeve 902 to the lower side thereof. During this process, the position of the clamping plate 903 does not move, and one end of the pressing plate 901 is turned over to provide pressure on the top of the column, so that the longitudinal position of the column is determined. At this time, the position of the socket of the column will correspond to the position of the moving block 6015, and at the same time, the bottom of the column is in close contact with the rubber seat 608;

[0050] Step 3: If Figure 3 and Figure 4As shown, during the extension of the extended end of the second cylinder 904, the U-shaped frame is sleeved on the moving block 6015, guided by the mounting strip 6016, and then positioned in cooperation with the baffle 6012, the extended end of the first cylinder 6013 is controlled to extend to half the length, the U-shaped frame has not yet contacted the socket of the column, the second lever slides from the middle of the L-shaped frame 602 to a section away from the first lever 603, at this time, the first lever 603 is cooperated to pull the transmission rod 604 and the booster piston 610, so that the air in the pressure regulating cylinder 609 enters the water storage tank 606 along the connecting pipe 605, and the air pressure in the water storage tank 606 is increased, as shown in FIG. Figure 2 and Figure 3 As shown, the clean water in the water tank 606 is injected into the bottom of the inner wall of the column along the U-shaped tube 607, and the column is cooled by the clean water entering the inner wall of the column.

Since the moving block 6015 cooperates with the mounting strip 6016 to guide and locate the position of the U-shaped frame, it is avoided that the position of the U-shaped frame is inaccurate during subsequent welding, which easily causes unstable welding. Then the welding tool 7 is controlled to weld the U-shaped frame, and the baffle plate 6012 cooperates with the positioning plate 10 to prevent the U-shaped frame from moving. After the welding is completed, the extended end of the first cylinder 6013 is controlled to shrink to half the length, and the moving block 6015 is withdrawn from the U-shaped frame. The clean water at the bottom of the inner wall of the column continues to cool the column; Figure 2-Figure 4 As shown, after the cooling of the column is completed, the extended end of the first cylinder 6013 is contracted to the shortest, and the booster piston 610 is reset by the action of the first tension spring, so that the air pressure in the water tank 606 becomes smaller, which facilitates the pumping of clean water at the bottom of the inner wall of the column back into the water tank 606 through the U-shaped tube 607 for subsequent use. During the welding of the U-shaped frame, the box door 5 is closed and the suction tooling 2 is opened to collect and filter the harmful gases in the outer shell 3.

7. The intelligent welding equipment for home metal columns according to claim 6 is characterized in that: A trapezoidal block (906) is slidably provided on the inner side wall of the housing (3), the top surface of the trapezoidal block (906) is rollingly connected to the roller, and a top rod (907) is fixedly installed on the front surface of the trapezoidal block (906), and a third lever is fixedly installed on the top of the top rod (907).

8. The intelligent welding equipment for household metal columns according to claim 7 is characterized in that: A pressing plate (901) is rotatably provided on the inner wall of the housing (3) above the trapezoidal block (906), one end of the pressing plate (901) contacts the top of the column, and the end of the pressing plate (901) away from the column is movably connected to the third lever.

9. A working method of a household metal column intelligent welding device according to any one of claims 1 to 8, characterized in that: The working method specifically comprises the following steps: Step 1: Open the box door (5). At this time, the extended end of the second cylinder (904) is at its shortest, and the roller is located on the inclined surface of the trapezoidal block (906). Due to the action of the second tension spring, the clamping plate (903) is close to the inner wall of the installation sleeve (902), which facilitates the insertion of the column into the installation sleeve (902); then the extended end of the second cylinder (904) is controlled to extend, so that the trapezoidal block (906) moves upward. When the roller rolls from the inclined surface of the trapezoidal block (906) to the upper part of the side close to the installation sleeve (902), the roller cooperates with the extrusion rod (905) to drive the clamping plate (903) to provide thrust to the side of the column, and cooperates with the inner wall of the installation sleeve (902) to preliminarily position the column. During this process, the push rod (907) drives the pressing plate (901) to flip, and there is still a gap between one end of the pressing plate (901) and the top of the column; Step 2: Control the extended end of the second cylinder (904) to continue to extend to the longest position, so that the roller rolls from the upper side of the trapezoidal block (906) close to the mounting sleeve (902) to the lower side thereof. During this process, the position of the clamping plate (903) does not move, and the pressing plate (901) presses the top of the column to determine the longitudinal position of the column. At this time, the position of the socket of the column will correspond to the position of the moving block (6015), and at the same time, the bottom of the column is in close contact with the rubber seat (608); Step 3: During the extension of the extended end of the second cylinder (904), the U-shaped frame is sleeved on the moving block (6015), guided by the mounting strip (6016), and then positioned by the baffle (6012), and the extended end of the first cylinder (6013) is controlled to extend to half its length. Before the U-shaped frame contacts the socket of the column, the second lever slides from the middle of the L-shaped frame (602) to a section away from the first lever (603). At this time, the transmission rod (604) and the booster piston (610) are pulled, so that the air in the pressure regulating cylinder (609) enters the water storage tank (606) along the connecting pipe (605), thereby increasing the air pressure in the water storage tank (606), and clean water is injected into the bottom of the inner wall of the column along the U-shaped pipe (607). The column is cooled by the clean water entering the inner wall of the column. Step 4: Continue to control the extended end of the first cylinder (6013) to extend to the longest, so that the moving block (6015) drives the U-shaped frame to be inserted into the socket of the column. Since the moving block (6015) cooperates with the installation strip (6016) to guide and locate the position of the U-shaped frame, the welding tool (7) is controlled to weld the U-shaped frame. After the welding is completed, the extended end of the first cylinder (6013) is controlled to shrink to half the length, and the moving block (6015) is withdrawn from the U-shaped frame. The clean water at the bottom of the inner wall of the column continues to cool the column.
