Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, specifically a welding device for electromagnetic valve production. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, serving as fundamental components in automation systems for fluid control. They are actuators, not limited to hydraulic or pneumatic systems, used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types include check valves, safety valves, directional control valves, and speed regulating valves.

[0003] For example, application number CN202220114113.4 discloses a welding equipment for producing solenoid valves, including a welding frame. The welding frame has a laser-resistant glass on its top front, a fixed seat at the center of the top of the welding frame, and a solenoid valve workpiece at the center of the surface of the fixed seat. A pressing protrusion is located at the center of one side of the laser-resistant glass, and a fixed plate is located on one side of the laser-resistant glass. A pressing groove is located on one side of the fixed plate corresponding to the pressing protrusion, and a micro switch is located inside the pressing groove. The pressing protrusion and the micro switch press against each other. A fixed base is located at the bottom of the fixed seat. This utility model uses a fixed base, a first rotating rod, a connecting rod, a second rotating rod, and a clamping block fixing structure to achieve rapid fixing and installation of the solenoid valve workpiece, saving more time when fixing the solenoid valve workpiece, thereby improving the welding efficiency of the solenoid valve workpiece and thus increasing the productivity of the solenoid valve.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of existing welding equipment that use a motor to drive the clamping block at the top of the threaded rod to clamp and fix the solenoid valve workpiece, resulting in a relatively complex result, high installation cost, and troublesome maintenance, the surface temperature of the solenoid valve workpiece is high after welding, making it impossible to immediately remove and place a new workpiece for welding. It is necessary to wait for it to cool down before operation, which consumes a lot of time. Utility Model Content

[0008] In a preferred embodiment of this utility model, the lifting mechanism includes an L-shaped plate, a second electric telescopic rod, a fixed sleeve, a lifting groove, and a connecting member.

[0012] As a preferred embodiment of this utility model, the left side of the arc-shaped fixing plate is provided with anti-slip texture, and the anti-slip texture is provided in a plurality of such textures and is distributed in a ring at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up an installation plate, a groove, an arc-shaped fixing plate, and a tension spring, allows the arc-shaped fixing plate inside the groove of the installation plate to contact the surface of the solenoid valve workpiece after the solenoid valve is welded. Then, the tension spring retracts and moves the arc-shaped fixing plate closer to the left side of the inner wall of the groove, thereby fixing the solenoid valve workpiece. This solves the problem that the surface temperature of the solenoid valve workpiece is high after welding, making it impossible to immediately remove and place a new workpiece for welding.

[0015] 2. This utility model, by setting up a clamping mechanism, after the solenoid valve workpiece is welded, removes the fixation of the solenoid valve workpiece through a fixing device. Then, by activating the first electric telescopic rod, the first electric telescopic rod drives the connecting plate to move. Then, the connecting plate drives the fixing rod to move. Then, the fixing rod drives the connecting block to move. Finally, the connecting block drives the arc-shaped fixing plate to move, causing the arc-shaped fixing plate to release tension and retract, thereby completing the clamping of the solenoid valve workpiece. Then, by setting up a lifting mechanism, by activating the second electric telescopic rod, the second electric telescopic rod drives the connecting piece to move. Then, the connecting piece drives the mounting plate to move inside the fixing sleeve at the bottom of the L-shaped plate. At the same time, the connecting piece moves inside the lifting groove through a sliding connection, thereby completing the lifting of the mounting plate.

[0016] 3. This utility model, by setting a slide rail groove and a slide rail block, allows the arc-shaped fixing plate to move as the connecting block moves, causing the arc-shaped fixing block to move as well. The slide rail block then moves within the slide rail groove, thus limiting the movement of the arc-shaped fixing plate and preventing it from tilting during movement, which could lead to insecure clamping. Furthermore, by setting a rotating groove, when the second electric telescopic rod moves the connecting piece upward within the lifting groove, the rotating groove and the lifting groove are connected. The second electric telescopic rod then moves the connecting piece within the rotating groove, thus completing the rotation of the mounting plate to the front side of the top of the welding frame after it has been raised.

[0023] refer to Figure 2 The clamping mechanism 11 includes a first electric telescopic rod 111, a connecting plate 112, a fixing rod 113, and a connecting block 114.

[0024] As a technical optimization of this utility model, by setting up a clamping mechanism 11, after the welding of the solenoid valve workpiece is completed, the solenoid valve workpiece is unfixed by the fixing device 5. Then, by activating the first electric telescopic rod 111, the first electric telescopic rod 111 drives the connecting plate 112 to move. Then, the connecting plate 112 drives the fixing rod 113 to move. Then, the fixing rod 113 drives the connecting block 114 to move. Finally, the connecting block 114 drives the arc-shaped fixing plate 9 to move, so that the arc-shaped fixing plate 9 drives the tension spring 10 to release tension and retract, thereby completing the clamping of the solenoid valve workpiece.

[0025] refer to Figure 3 The lifting mechanism 12 includes an L-shaped plate 121, a second electric telescopic rod 122, a fixed sleeve 123, a lifting groove 124, and a connector 125. The L-shaped plate 121 is fixedly connected to the left side of the top of the welding frame 1. The fixed sleeve 123 is fixedly connected to the bottom of the inner side of the L-shaped plate 121. The lifting groove 124 is opened at the bottom of the right side of the surface of the fixed sleeve 123. The second electric telescopic rod 122 is fixedly connected to the left side of the top of the welding frame 1. The connector 125 is fixedly connected to the output end of the second electric telescopic rod 122. The right side of the connector 125 is fixedly connected to the left side of the mounting plate 7. The connector 125 is slidably connected to the lifting groove 124.

[0026] As a technical optimization of this utility model, by setting up a lifting mechanism 12, by activating the second electric telescopic rod 122, the second electric telescopic rod 122 drives the connecting piece 125 to move, and then the connecting piece 125 drives the mounting plate 7 to move inside the fixed sleeve 123 at the bottom of the inner side of the L-shaped plate 121. At the same time, the connecting piece 125 moves inside the lifting groove 124 through a sliding connection, thereby completing the lifting of the mounting plate 7.

[0027] refer to Figure 3 The inner walls of the groove 8 are provided with slide rail grooves 13 on both sides, and slide rail blocks 14 are fixedly connected to both sides of the arc-shaped fixing plate 9. The slide rail blocks 14 are slidably connected to the slide rail grooves 13.

[0028] As a technical optimization of this utility model, by setting the slide rail groove 13 and the slide rail block 14, when the connecting block 114 drives the arc-shaped fixing plate 9 to move, the arc-shaped fixing block drives the slide rail block 14 to move, and then the slide rail block 14 moves inside the slide rail groove 13, thereby limiting the movement of the arc-shaped fixing plate 9 and preventing it from tilting during the movement, which would cause the clamping to be unstable.

[0029] refer to Figure 2 A rotating groove 15 is provided on the top of the surface of the fixed sleeve 123. The bottom of the inner wall of the rotating groove 15 is connected to the top of the inner wall of the lifting groove 124. The rotating groove 15 is slidably connected to the connector 125.

[0030] As a technical optimization of this utility model, by setting a rotating groove 15, when the second electric telescopic rod 122 drives the connecting piece 125 to rise inside the lifting groove 124, the rotating groove 15 and the lifting groove 124 are connected at the same time, and then the second electric telescopic rod 122 drives the connecting piece 125 to move inside the rotating groove 15, thereby completing the rotation of the mounting plate 7 to the front side of the top of the welding frame 1 after it rises.

[0031] refer to Figure 2 Damping rods 16 are fixedly connected to both sides of the left side of the inner wall of the groove 8. The right end of the damping rod 16 is fixedly connected to the left side of the arc-shaped fixing plate 9. The tension spring 10 is sleeved on the surface of the damping rod 16.

[0032] As a technical optimization of this utility model, by setting a damping rod 16, the safety and stability of the tension spring 10 during tension raising and releasing are improved, thereby extending the service life of the tension spring 10.

[0033] refer to Figure 2 The left side of the arc-shaped fixing plate 9 is provided with anti-slip texture 17, which is provided in several and distributed in a ring at equal intervals.

[0034] As a technical optimization of this utility model, by setting anti-slip texture 17, the friction force generated by the contact between the arc-shaped fixing plate 9 and the solenoid valve workpiece is increased, thereby preventing slippage when clamping the solenoid valve workpiece.

[0035] The working principle and usage process of this utility model are as follows: After the solenoid valve welding is completed, the solenoid valve workpiece is unfixed using the fixing device 5. Then, by activating the first electric telescopic rod 111, the first electric telescopic rod 111 moves the connecting plate 112, which in turn moves the fixing rod 113. The fixing rod 113 then moves the connecting block 114, which in turn moves the arc-shaped fixing plate 9. This causes the arc-shaped fixing plate 9 to release tension and retract the tension spring 10, thus clamping the solenoid valve workpiece. Then, by activating the second electric telescopic rod 122... The second electric telescopic rod 122 drives the connecting piece 125 to move, and then the connecting piece 125 drives the mounting plate 7 to move inside the fixed sleeve 123 at the bottom of the inner side of the L-shaped plate 121. At the same time, the connecting piece 125 moves inside the lifting groove 124 through a sliding connection, thereby driving the mounting plate 7 to rise. Meanwhile, the rotating groove 15 and the lifting groove 124 are connected, and then the second electric telescopic rod 122 drives the connecting piece 125 to move inside the rotating groove 15, thereby completing the lifting and rotation of the mounting plate 7 to the front side of the top of the welding frame 1. Thus, it has the advantage of picking up the solenoid valve workpiece.

[0036] In summary, this welding device for solenoid valve production, through the arrangement of mounting plate 7, groove 8, arc-shaped fixing plate 9, and tension spring 10, allows the solenoid valve workpiece to be fixed after welding. The arc-shaped fixing plate 9, located inside the groove 8 of mounting plate 7, contacts the surface of the solenoid valve workpiece. Then, the tension spring 10 contracts, causing the arc-shaped fixing plate 9 to move towards the left side of the inner wall of the groove 8. This solves the problem that the surface temperature of the solenoid valve workpiece is high after welding, making it impossible to immediately remove and place a new workpiece for welding; operation must wait for it to cool down, a process that consumes a significant amount of time.
