Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to an oil drain plug welding machine for an oil pan assembly. Background Art

[0002] The oil pan is an important component of the engine, and the oil plug in the oil pan performs key functions such as sealing, oil filling and draining. In scenarios such as automobile manufacturing or engine maintenance, the welding quality of the oil plug in the oil pan assembly is directly related to the overall performance and reliability of the oil pan.

[0003] Traditional welding methods usually use manual arc welding and resistance welding to cooperate with each other for welding. Resistance welding is performed by manual loading and unloading. Manually placing the workpiece for a long time may easily lead to the possibility of placing it in the wrong direction, resulting in the welding position being located at the diagonal position where the welding machine falls, causing damage to the welded workpiece and affecting production. Manually picking up the workpiece will transfer static ions into the workpiece. The static electricity generated during welding will cause the welding equipment components to be damaged by static electricity, causing equipment damage and safety accidents. The impurities contained in the smoke generated by welding may clog the collection device and increase the equipment maintenance cost. At the same time, the oil pan and the oil plug oil port have different materials, and there are differences in physical properties such as melting point and expansion coefficient. Uneven heat distribution during welding can easily cause welding defects such as cracks and pores. Therefore, the present application provides an oil pan assembly drain plug welding machine to meet the needs. Summary of the Invention

[0019] By setting up a flue gas collection component, the physical adsorption and thermal conductivity of the metal partition itself can condense the gaseous substances in the smoke and increase the amount of smoke attached to the partition, thereby reducing the amount of smoke to be subsequently processed. At the same time, some particulate impurities in the smoke are attached to its surface, avoiding the impurities in the smoke from being directly adsorbed on the inner wall of the collection box and condensing to cause blockage, making manual cleaning more convenient.

[0020] By setting up a glycerin pool and a heat conducting plate and placing modules for heating, the welded workpiece can be kept warm. The unwelded workpiece can also be preheated to evaporate the surface moisture of the unwelded workpiece material.

[0045] like Figures 1 to 6As shown, the clamping assembly 5 includes a mounting frame 51, which is symmetrically mounted on the top of the electric control turntable 3. There are two mounting frames 51, and a placement module 510 is installed on the top of the mounting frame 51. Two sliding blocks 52 are symmetrically mounted on the inner side of each mounting frame 51. Each sliding block 52 slides in the slide groove of the mounting frame 51 respectively. The bottom end of each sliding block 52 is connected to a connecting rod 53, and the connecting rod 53 rotates at the bottom end of the corresponding sliding block 52. A rotating plate 54 is connected between the two connecting rods 53, and the rotating plate 54 rotates at the bottom end of the mounting frame 51. The two connecting rods 53 are respectively connected to the rotating plate 54. The outer side of the rotating plate 54 is rotated, and a cylinder 55 is connected to one side of the rotating plate 54. The cylinder 55 is installed at the bottom end of the mounting frame 51. A mounting box 56 is connected to one side of each sliding block 52. Three positioning pins 560 are installed at equal angles on the inner side of the mounting box 56. A stopper 57 is installed on the inner side of the mounting box 56. A positioning pin 560 is nested on the inner side of the stopper 57. Two mounting blocks 58 are symmetrically installed on the inner side of the mounting box 56. The two mounting blocks 58 slide on the inner side of the mounting box 56 respectively. A contact block 59 is connected to the end of each mounting block 58, and the other two positioning pins 560 are nested on the inner side of the mounting block 58 respectively.

[0046] By setting up the clamping component 5, the operator can place the oil pan assembly workpiece that needs to be welded at the oil port position above the placement module 510 near the outside of the cabinet 1, and start the equipment through the control panel 2. The control panel 2 controls the closing of the cylinder 55, so that the protruding end of the cylinder 55 pulls the rotating plate 54 to rotate, and the two connecting rods 53 connected to the outside of the rotating plate 54 rotate along with the rotation of the rotating plate 54, so that the sliding blocks 52 connected to the two connecting rods 53 are respectively subjected to pulling forces and slide in the corresponding sliding grooves of the mounting frame 51, so that the two sliding blocks 52 on the mounting frame 51 move toward the center position at the same time. When the contact block 59 at the end of the mounting block 58 contacts the outside of the workpiece, the contact block 59 is subjected to resistance force, and the corresponding mounting block 58 slides and changes a small angle on the inside of the mounting box 56 through the positioning pin 560 nested inside. The inclined surface at the end of the mounting block 58 contacts the inclined surface at the end of the stop block 57, so that the stop block 57 follows the mounting block 58 to slide on the inner side of the mounting box 56 under the action of the corresponding positioning pin 560, pushing the other mounting block 58 in the mounting box 56 so that the contact block 59 at the end can also fully contact the side wall of the workpiece. At the same time, the two mounting blocks 58 in the same mounting box 56 are subjected to the resistance force of the side wall of the workpiece, and contact the inclined surfaces on both sides of the stop block 57 to form a mutual resistance force, so that the contact blocks 59 in the same mounting box 56 can be clamped tightly against the side wall of the workpiece. Due to the close fit between the contact block 59 and the side wall of the workpiece, the workpiece is not easily displaced under the generated vibration or external force interference, which can effectively ensure the position accuracy of the workpiece during processing or detection, and has the ability to clamp workpieces within a certain size range, with high versatility.

[0047] like Figures 7 to 10As shown, the adjusting assembly 6 comprises a circular arc sliding rail 61 mounted on the inner side of the mounting frame 51, the inner side of the circular arc sliding rail 61 is nested with a mounting seat 62, the mounting seat 62 slides on the inner side of the circular arc sliding rail 61, the top end of the mounting seat 62 is bolted with an electrode plate 620, one side of the mounting seat 62 is connected with a sliding rod 63, the outer side of the sliding rod 63 is sleeved with a sliding groove seat 64, the sliding rod 63 slides in the inner side of the sliding groove seat 64, the sliding groove seat 64 is mounted on the inner wall of the mounting frame 51 and rotates on the inner wall of the mounting frame 51, the bottom end of the sliding rod 63 is connected with a positioning rod 65, the outer side of the positioning rod 65 is sleeved with a rotating disc 66, the positioning rod 65 slides in the opening slot of the rotating disc 66, the bottom end of the rotating disc 66 is mounted with a driving motor 67, the driving motor 67 is nested and mounted on the inner side of the mounting frame 51, the inner side of the sliding rod 63 is nested with a guide rod 68, the guide rod 68 slides in the inner side of the sliding rod 63, the top end of the guide rod 68 is connected with a conductive rod 69, the conductive rod 69 is connected with the grounding wire position of the cabinet 1 through wires, one side of the circular arc sliding rail 61 is symmetrically connected with two guide rails 610, the guide rails 610 are arranged as circular arc inclined rails, and the guide rod 68 slides on the top end of the two guide rails 610.

[0048] By setting the adjustment component 6, the control panel 2 then starts the electric control turntable 3 to perform a 180° reversal, switching the workstation close to the outside of the cabinet 1 with the workstation close to the inside of the cabinet 1. The visual camera 4 identifies the welding position of the workpiece oil port, and transmits the data to the control panel 2 according to the operator's placement of the workpiece (the welding oil port is located on the outside or inside of the electric control turntable 3). The control panel 2 determines the direction according to the position, starts the drive motor 67 to rotate in the corresponding direction, and the drive motor 67 drives the rotating disk 66 to rotate. The positioning rod 65 passes through the opening slot of the rotating disk 66. The sliding rod 63 is driven to move, and the mounting seat 62 connected to the end of the sliding rod 63 slides on the inner side of the arc slide rail 61 toward the bottom of the welding oil port position, so that the electrode plate 620 can be maintained at the bottom of the welding oil port position. According to the distance between the position of the mounting seat 62 in the arc slide rail 61 and the moving position of the positioning rod 65 driven by the rotating disk 66, the sliding rod 63 performs auxiliary sliding on the inner side of the slide seat 64 to assist in adjusting the extension length of the sliding rod 63. At the same time, during the rotation of the sliding rod 63, the guide rod 68 located on the inner side of the sliding rod 63 follows the movement, and the guide rod 68 moves in the guide The surface of the guide rail 610 is in contact and sliding, so that the conductive rod 69 gradually extends from the inner side of the sliding rod 63 and contacts the inner wall of the workpiece, and the guide rod 68 slides on the surface of the guide rail 610 to contact and scrape the inner wall of the workpiece, thereby introducing the residual static electricity in the workpiece into the conductive rod 69, and then leading it to the machine tool grounding wire position through the wire connected to the conductive rod 69. The guide rod 68 slides in contact with the guide rail 610, so that the conductive rod 69 extends and contacts the inner wall of the workpiece, thereby leading the residual static electricity in the workpiece, thereby improving the safety and stability of welding. The welding gun holder 8 slides on the inner wall of the cabinet 1, so that the welding gun holder 8 moves the welding gun module 9 to the welding oil port position of the workpiece, pushes the welding gun module 9 out from the welding gun holder 8, contacts the workpiece, and makes the workpiece move vertically downward and contact the electrode plate 620. During the process, the placement module 510 shrinks at the top of the mounting frame 51 to complete the welding, and the placement module 510 is reset. There is no need for the operator to unify the placement direction of the workpiece, which reduces the difficulty of the operator's workpiece installation and improves the processing efficiency. After the welding is completed, the electric control turntable 3 will start again and rotate the workstation where the welding has been completed to the outside of the cabinet 1 so that the operator can perform subsequent inspection or transportation work.

[0049] like Figures 11 to 14As shown, the fume collection assembly 7 includes a collection hood 71, which is installed on one side of the welding gun holder 8. One end of the collection hood 71 is connected to a collection box 72 through a pipeline. The collection box 72 is installed on one side of the cabinet 1. A metal partition 73 is installed on the inner side of the collection box 72. The metal partition 73 is made of stainless steel and slides on the inner side of the collection box 72. A guide pipe 74 is installed on the bottom end of the metal partition 73. The bottom end of the metal partition 73 is connected to a filter box 75. The filter box 75 slides on the inner side of the collection box 72. An activated carbon layer 76 is provided on the inner side of the filter box 75. A heat pipe 77 is installed on the inner side of the filter box 75. The heat pipe 77 is made of metal copper. A glycerol pool 78 is installed on the bottom end of the heat pipe 77. The glycerol pool 78 is installed at the bottom end of the collection box 72. One side of the glycerol pool 78 is connected to multiple heat conducting plates 79 through a pipeline. The heat conducting plates 79 are respectively installed on the inner side of the placement module 510.

[0050] By setting up a fume collection component 7, during the welding process, by connecting the jet fan (not marked in the figure) in the production workshop with the collection box 72, the collection hood 71 generates suction to absorb the fume generated by welding, and the fume enters the inner side of the collection box 72 through the pipeline and contacts the metal partition 73. The welding fume contacts the metal partition 73. Since the surface of the metal partition 73 is relatively smooth and the temperature is relatively low, some particulate impurities in the fume will adhere to the surface of the metal partition 73 under the action of physical adsorption and gradually accumulate on the metal partition 73. The metal partition 73 may cause certain high-temperature components in the fume to cool down rapidly due to its own thermal conductivity, causing condensation of the gaseous substances therein, further increasing the amount of fume attached to the metal partition 73. As the time of absorbing fume goes by, a thin layer of fume covering is formed on the surface of the metal partition 73 to prevent the impurities in the fume from condensing and adsorbing on the inner wall of the collection box 72, causing blockage in the collection box 72 and making it difficult to clean. The operator can remove the metal partition 73 from the inner side of the collection box 72 for processing. After passing through the metal partition 73, the smoke enters the guide pipe 74, forming a spiral airflow. Harmful substances enter the filter box 75 and are filtered and absorbed by the activated carbon layer 76. The remaining gas is discharged through the jet fan (not marked in the figure) in the production workshop. The welding smoke contacts the heat pipe 77 inside the filter box 75, and the heat contained in the welding smoke is transferred to the inner side of the heat pipe 77 through heat transfer. The bottom end of the heat pipe 77 is immersed in the glycerin pool 78 to transfer the heat and transfer the glycerin heat to the heat conduction plate 79 through the pipeline. The heat conduction plate 79 heats the placement modules 510 on the two mounting frames 51 to keep the welding workpieces warm. It can also preheat the unwelded workpieces and evaporate the moisture on the surface of the unwelded workpiece materials. At the same time, it reduces the temperature difference between the welding area and other positions of the workpiece, reduces the deformation of the workpiece and the situation of residual stress tearing the workpiece, and reduces the generation of welding pores.

[0051] The working principle of the technical solution provided by the present invention is as follows:

[0052] The operator can place the oil pan assembly workpiece that needs to be welded at the oil port position on top of the placement module 510 near the outside of the cabinet 1, and start the equipment through the control panel 2. The control panel 2 controls the closing of the cylinder 55, so that the extended end of the cylinder 55 pulls the rotating plate 54 to rotate, and the two connecting rods 53 connected to the outside of the rotating plate 54 rotate along with the rotation of the rotating plate 54, so that the sliding blocks 52 connected to the two connecting rods 53 are respectively subjected to pulling forces and slide in the corresponding sliding grooves of the mounting frame 51, so that the two sliding blocks 52 on the mounting frame 51 move toward the center position at the same time. When the contact block 59 at the end of the mounting block 58 contacts the outside of the workpiece, the contact block 59 is subjected to a resistance force, and the corresponding mounting block 58 slides and changes a small angle on the inside of the mounting box 56 through the locating pin 560 nested inside. The inclined surface at the end of 8 contacts the inclined surface at the end of the stop block 57, so that the stop block 57 follows the mounting block 58 to slide on the inner side of the mounting box 56 under the action of the corresponding positioning pin 560, and pushes the other mounting block 58 in the mounting box 56, so that the contact block 59 at the end can also fully contact the side wall of the workpiece. At the same time, the two mounting blocks 58 in the same mounting box 56 are subjected to the resistance force of the side wall of the workpiece, and contact the inclined surfaces on both sides of the stop block 57 to form a mutual resistance force, so that the contact blocks 59 in the same mounting box 56 can be clamped tightly against the side wall of the workpiece. Due to the close fit between the contact block 59 and the side wall of the workpiece, the workpiece is not easily displaced under the generated vibration or external force interference, which can effectively ensure the position accuracy of the workpiece during processing or detection, and has the ability to clamp workpieces within a certain size range, with high versatility.

[0053] Then the control panel 2 starts the electric control turntable 3 to perform a 180° reversal, switching the workstation near the outside of the cabinet 1 with the workstation near the inside of the cabinet 1, and identifies the workpiece oil port welding position through the visual camera 4. According to the operator's placement of the workpiece (the welding oil port position is on the outside or inside of the electric control turntable 3), the data is transmitted to the control panel 2. The control panel 2 determines the direction according to the position, starts the drive motor 67 to rotate in the corresponding direction, and the drive motor 67 drives the rotating disk 66 to rotate. The positioning rod 65 slides in the open groove of the rotating disk 66 to drive the sliding rod 63 to move. The mounting seat 62 connected to the end of the sliding rod 63 slides on the inner side of the arc slide rail 61 toward the bottom of the welding oil port position, so that the electrode plate 620 can be maintained at the bottom of the welding oil port position. According to the distance between the position of the mounting seat 62 in the arc slide rail 61 and the moving position of the positioning rod 65 driven by the rotating disk 66, the sliding rod 63 performs auxiliary sliding on the inner side of the slide groove seat 64 to assist in adjusting the extension length of the sliding rod 63. At the same time, during the rotation of the sliding rod 63, the guide rod 68 located inside the sliding rod 63 moves accordingly, and the guide rod 68 contacts and slides on the surface of the guide rail 610, so that the conductive rod 69 gradually extends from the inner side of the sliding rod 63 and contacts the inner wall of the workpiece. The guide rod 68 slides on the surface of the guide rail 610 to contact and scrape the inner wall of the workpiece, and the residual static electricity in the workpiece is introduced into the conductive rod 69, and is led out to the machine tool grounding wire position through the wire connected to the conductive rod 69. The welding gun holder 8 is inside the cabinet 1. The welding gun module 9 is pushed out from the welding gun holder 8 and contacts the workpiece, so that the workpiece moves vertically downward and contacts the electrode plate 620. During the process, the placement module 510 is retracted at the top of the mounting frame 51 to complete the welding. The placement module 510 is reset. After the welding is completed, the electric control turntable 3 will start again and rotate the workstation where the welding is completed to the outside of the cabinet 1 so that the operator can carry out subsequent inspection or transportation work.

[0054] During the welding process, the jet fan (not marked in the figure) in the production workshop is connected to the collection box 72, so that the collection hood 71 generates suction to absorb the smoke generated by welding. The smoke enters the inner side of the collection box 72 through the pipeline and contacts the metal partition 73. The welding smoke contacts the metal partition 73. Since the surface of the metal partition 73 is relatively smooth and the temperature is relatively low, some particulate impurities in the smoke will adhere to the surface of the metal partition 73 under the action of physical adsorption and gradually accumulate on the metal partition 73. The metal partition 73 may cause certain high-temperature components in the smoke to cool down rapidly due to its own thermal conductivity, causing the gaseous substances therein to condense, further increasing the amount of smoke attached to the metal partition 73. As the time of absorbing smoke goes by, a thin layer of smoke covering is formed on the surface of the metal partition 73 to prevent impurities in the smoke from being adsorbed on the inner wall of the collection box 72, causing blockage in the collection box 72 and making it difficult to clean. The operator can The metal partition 73 is pulled out from the inner side of the collection box 72 for processing. After passing through the metal partition 73, the smoke enters the guide pipe 74, forming a spiral airflow. Harmful substances enter the filter box 75 and are filtered and absorbed by the activated carbon layer 76. The remaining gas is discharged through the jet fan (not marked in the figure) in the production workshop. The welding smoke contacts the heat pipe 77 inside the filter box 75, and the heat contained in the welding smoke is transferred to the inner side of the heat pipe 77 through heat transfer. The bottom end of the heat pipe 77 is immersed in the glycerin pool 78 to transfer the heat and transfer the glycerin heat to the heat conduction plate 79 through the pipeline. The heat conduction plate 79 heats the placement modules 510 on the two mounting frames 51 to keep the welding workpieces warm. It can also preheat the unwelded workpieces and evaporate the moisture on the surface of the unwelded workpiece materials. At the same time, the temperature difference between the welding area and other positions of the workpiece is reduced, the deformation of the workpiece and the residual stress tearing of the workpiece are reduced, and the generation of welding pores is reduced.
