Description

Technical Field

[0001] The invention belongs to the technical field of welding devices, and in particular relates to an automatic welding device for an electric actuator housing. Background Art

[0002] A spot welder is a resistance welding device, which is mainly used to connect two or more metal parts together by heating and applying pressure to form a permanent weld, for example, an automatic welding device for a separate compressor housing proposed in patent publication number CN213560491U.

[0003] The surface nameplate of the electric actuator is an important component used to identify the relevant information of the equipment. The nameplate is a thin metal plate, which is usually welded to the surface of the electric actuator housing using a spot welder;

[0004] During the spot welding operation of the electric actuator housing and the nameplate, if impurities such as oil, rust and oxide scale remain on the surface of the nameplate, the contact resistance at the welding point will be significantly increased. When welding with power on, this uneven resistance will cause an imbalance in heat distribution, which can easily lead to cold welding. Although such cold welding points appear to be connected in appearance, the actual bonding strength is seriously insufficient and it is difficult to meet the requirements of long-term use. However, the spot welding devices currently on the market generally lack effective detection functions for the welding strength of the nameplate, and are unable to identify such quality risks in a timely manner, which in turn leads to uneven welding quality of some nameplates, affecting the overall quality and reliability of the electric actuator.

[0035] The grinding assembly 33 is arranged on the lower side of the support frame 2 and is used for grinding the worn welding electrode 7. The grinding assembly 33 includes a screw linear module 331 fixedly connected to the upper inner wall of the support frame 2.

[0036] Two placement plates 35 are fixedly connected to the upper side wall of the mounting frame 1, and the side walls of the two placement plates 35 are fixedly connected with transverse electric push rods 36. The movable end of the transverse electric push rods 36 passes through the placement plates 35 and is fixedly connected with a push plate 37. The electric actuator housing is located between the two push plates 37. The upper side wall of the mounting frame 1 is fixedly connected with a placement frame 38. The placement frame 38 is a U-shaped structure. The nameplate is stacked in the placement frame 38, which can clamp and fix the electric actuator housing.

[0037] The walls of the air intake pipe 82 and the air exhaust pipe 12 are fixedly connected to a pressure relief pipe 39 , and a pressure relief valve 40 is provided in the pressure relief pipe 39 to discharge the gas inside the air intake pipe 82 and the air exhaust pipe 12 .

[0038] The operating principle of the present invention is now described as follows: the operator places the housing of the electric actuator between the two push plates 37, and makes the rear side wall of the housing contact the inner wall of the support frame 2, and then the operator transmits a start electrical signal to the control cabinet 3 through the button on the surface of the control cabinet 3. After receiving the electrical signal, the control cabinet 3 will control the air pump 11 to work, and the air pump 11 will extract the gas inside the material barrel 81 through the suction pipe 12, and the external gas will enter the material barrel 81 through the suction cup 9 and the suction pipe 82. While the air pump 11 is working, the control cabinet 3 will also control the vertical electric push rod 4 works, the vertical electric push rod 4 drives the adjustment motor 5, the rotating plate 6 and the material taking component 8 to move downward together through the pressure sensor, so that the suction cup 9 contacts the top nameplate in the placement frame 38. When the suction cup 9 contacts the top nameplate, the external air will not enter the material taking barrel 81, so that the material taking barrel 81 and the suction cup 9 are in a negative pressure state, and the suction cup 9 can be used to absorb the top nameplate. In addition, the control cabinet 3 detects that the negative pressure in the material taking barrel 81 reaches the set pressure (0.2 standard atmospheric pressure) through the air pressure sensor 15 on the left side, and the control cabinet 3 controls the air pump 11 to stop At the same time, the pressure racks 24 on both sides will squeeze the top nameplate and apply a certain squeezing force to the nameplate. When the suction cup 9 contacts the top nameplate, it will hinder the movement of the suction cup 9 and the upper components. Therefore, the pressure sensor will detect the squeezing force. When the pressure sensor detects that the squeezing force reaches the set threshold (10N), the pressure sensor will send an electrical signal to the control cabinet 3. After receiving the electrical signal, the control cabinet 3 will control the vertical electric push rod 4 to stop working, and control the vertical electric push rod 4 to drive the adjusting motor 5, the rotating plate 6, the material taking component 8 and the nameplate. When the nameplate moves upward to the set position, the contact control cabinet 3 will also control the adjustment motor 5 to work, and the adjustment motor 5 will drive the rotating plate 6 to rotate 180 degrees, so that the nameplate moves to the top of the shell. Then, the control cabinet 3 controls the vertical electric push rod 4 to drive the nameplate to move downward, so that the nameplate fits in the set area on the shell surface. Referring to the above principle, when the nameplate and the shell fit, the extrusion force will be detected by the pressure sensor. When the control cabinet 3 detects that the extrusion force between the nameplate and the shell reaches the set threshold (20N) through the pressure sensor, the control cabinet 3 will control the vertical electric push rod 4 to stop working;

[0039] At the same time, the control cabinet 3 will also control the air pump 11 to continue working, and control the pressure relief valve 40 on the left to open. The air pump 11 draws in external gas through the exhaust pipe 12 and the pressure relief pipe 39 on the left, and transports it to the annular pipe 19 through the gas pipe 13. At this time, the multiple first control valves 21 are in the open state, and the external gas will be transported to the welding cylinder 162 through the connecting pipe 20, so that the air pressure above the piston plate 17 increases. Under the action of the air pressure, the piston plate 17 will drive the insert cylinder 18 and the welding electrode 7 to move downward together. During the downward movement, the welding electrode 7 will contact the surface of the nameplate. When the welding electrode 7 stops moving, the air above the piston plate 17 The pressure will continue to increase. After the control cabinet 3 detects that the air pressure above the piston plate 17 reaches the set threshold value (0.5 standard atmospheric pressure) through the air pressure sensor 15 on the right, the control cabinet 3 will control the air pump 11 to stop working, and control the pressure relief valve 40 on the left to close. At the same time, the external welder is controlled to transmit the welding current to the welding electrode 7 through the conductive slide mechanism, and the welding electrode 7 is used to weld the nameplate (the surface of the mounting frame 1 is provided with an electrode sheet, which can form a current loop between the welding electrode 7 and the external welder), and in the process of welding, a certain pressure is applied to the nameplate through the pressing frame 24 to further ensure the tightness of the contact between the nameplate and the shell;

[0040] When the welding work is finished, the control cabinet 3 will control the pressure relief valve 40 on the right to open, so that the internal gas of the welding tube 162 and the ring tube 19 is discharged through the pressure relief pipe 39 on the right. The welding electrode 7 will move upward to the initial position in the welding tube 162 under the tension of the upper spring. At the same time, the control cabinet 3 will also control the air pump 11 to repeat the above steps to make the negative pressure value between the suction cup 9 and the nameplate reach 0.2 standard atmospheric pressure. At the same time, the control cabinet 3 will also control the vertical electric push rod 4 to work, so that the vertical electric push rod 4 drives the rotating plate 6 and the suction cup 9 and other components to move upward together, and the suction cup 9 will continue to suck Attached is the welded nameplate. When the nameplate welding strength reaches the standard, the nameplate will not separate from the shell during the upward movement of the suction cup 9. During the upward movement of the material taking barrel 81, the suction cup 9 will drive the suction pipe 82 and the piston ring 10 to move downward relatively in the material taking barrel 81 due to the adsorption of the nameplate. After the piston ring 10 moves to the bottom of the air pressure hole 41, the external air will enter the material taking barrel 81 through the air pressure hole 41, above the piston ring 10, and the air will also enter the suction cup 9 through the air suction hole, so that the negative pressure value between the suction cup 9 and the nameplate is reduced, thereby separating the suction cup 9 from the nameplate.

[0041] Similarly, when the nameplate or shell has a nameplate welding strength that does not meet the standard as a whole due to impurities such as residual oil, rust and oxide scale on the surface, the nameplate will be separated from the shell during the upward movement of the suction cup 9, and will remain in an adsorbed state with the suction cup 9. When the vertical electric push rod 4 drives the rotating plate 6 and other components to move upward to the initial height, the control cabinet 3 will detect the air pressure inside the material taking barrel 81 through the air pressure sensor 15 on the left. When it is detected that the air pressure inside the material taking barrel 81 is still at a negative value, it indicates that the nameplate is separated from the shell. The control cabinet 3 will control the internal buzzer module to remind the operator. The operator can control the pressure relief valve 40 on the left side of the control cabinet 3 to open, remove the nameplate, and clean the impurities such as oil, rust and oxide scale remaining on the surface of the nameplate and the shell, and then put the nameplate back into the placement frame 38 to repeat the welding steps.

[0042] When the nameplate and the shell are being welded, because a certain welding electrode 7 is worn out, or there are impurities such as oil, rust and scale on the nameplate, resulting in the welding point strength not meeting the standard, during the upward movement of the suction cup 9 (after the suction cup 9 rises to a certain height, the other welding points meet the strength standards, referring to the above principle, the suction cup 9 will separate from the nameplate), the corner of the nameplate whose welding point does not meet the standard will be lifted up with the movement of the suction cup 9, and the lifted corner of the nameplate will continue to push the pressing frame 24 on that side, so that the pressing frame 24 and the lifting block 222 and the conductive block 25 on that side do not slide downward in the detection tube 221 on that side, or the sliding distance is short, and the welding points at other corners of the nameplate are not up to standard. When the strength of the point is in a normal state, the pressure frame 24 at that place will move downward relatively during the process of the suction cup 9 moving upward, and the pressure frame 24 on that side will drive the lifting rod 23, the lifting block 222 and the conductive block 25 on that side to move downward together. During the downward movement, the conductive block 25 will contact the resistor plate 26 on that side, and the conductive block 25 is electrically connected to the external power supply. The lower end of the resistor plate 26 is electrically connected to the control cabinet 3. After the conductive block 25 and the resistor plate 26 are in contact near the lower end, the resistance of the circuit connected to the control cabinet 3 will be reduced. When the external voltage remains unchanged, the current intensity transmitted to the circuit of the control cabinet 3 will be increased, and the control cabinet 3 will be electrically connected to the external power supply. The strength of the electrical signals transmitted by the multiple resistor plates 26 is detected. When it is detected that the strength of the electrical signals transmitted by a certain resistor plate 26 is significantly higher than the strength of the electrical signals transmitted by the other resistor plates 26, the control cabinet 3 will use the internal buzzer module to remind the operator to manually clean and re-weld the nameplates with substandard welding points. At the same time, the air pump 11 is controlled to work for 1 second, and the second control valve 28 corresponding to the resistor plate 26 is controlled to open for 1 second. The air pump 11 will transmit the external airflow to the corresponding recording cylinder 271 through the air pipe 13, the annular pipe 19, the connecting pipe 20 and the bent pipe 272, so that the air pressure under the piston seat 30 increases, and the piston seat 30 will move upward to the distance The trigger switch 32 stays at a position of three centimeters, and when the gas no longer enters the recording cylinder 271, the gas inside the recording cylinder 271 will be slowly discharged through the microporous tube 31 and will be completely discharged within one hour. When the strength of the nameplate welding point is not up to standard due to the wear of a certain welding electrode 7, the above principle will be repeated when the next nameplate is welded, so that the gas continues to enter the recording cylinder 271, the piston seat 30 will continue to move upward, and squeeze the trigger switch 32, and the piston seat 30 will stop moving. The control cabinet 3 detects that the air pressure below the piston seat 30 reaches the set threshold value (0.05 standard atmospheric pressure), the control cabinet 3 will control the air pump 11 to stop working, and the trigger switch 32 will send an electrical signal to the control cabinet 3, indicating that the welding electrode 7 on this side is worn, resulting in the welding point strength not meeting the standard. After the rotating plate 6 moves upward to the set height, the control cabinet 3 will control the adjustment motor 5 to work, control the multiple welding electrodes 7 to rotate to the right, and control the screw linear module 331 to work, and use the screw linear module 331 to drive the moving frame 332 and the electric grinding mechanism 34 to move to the bottom of the multiple welding electrodes 7. At this time, the distance between the electric grinding mechanism 34 and the welding electrode 7 is two centimeters. After the screw linear module 331 stops working, the control cabinet 3 The air pump 11 will be controlled to work, and the corresponding first control valve 21 will be controlled to open. The air pump 11 will deliver external gas to the piston plate 17 on this side, so that the piston plate 17 drives the worn welding electrode 7 to move downward together, and the welding electrode 7 will contact the electric grinding mechanism 34. After the air pressure sensor 15 on the right detects that the air pressure on the piston plate 17 reaches 0.4 standard atmospheric pressure, the contact force between the welding electrode 7 and the electric grinding mechanism 34 is 10N, and the control cabinet 3 will control the air pump 11 to stop working, and control the first control valve 21 on this side to close, and then control the electric grinding mechanism 34 to work for thirty seconds, and the worn welding electrode 7 can be polished.
