Description

Technical Field

[0001] The invention relates to the technical field of internal magnetic rotor transfer devices, in particular to a transfer device for welding processing of an internal magnetic rotor of a magnetic pump. Background Art

[0002] In the manufacturing process of magnetic pumps, the welding process of the inner magnetic rotor is a key process step. In the traditional welding process of the inner magnetic rotor, the position of the inner magnetic rotor and the loading and unloading of the inner wear-resistant layer and the outer wear-resistant layer are generally adjusted by manual operation. Especially after welding is completed, the inner magnetic rotor needs to be placed in water for cooling. After cooling, the inner magnetic rotor needs to be dried to prevent the loss of magnetism of the inner magnetic rotor and improve the stability and reliability of the inner magnetic rotor. This kind of transportation work during welding not only increases the workload of the staff, but also greatly reduces the production efficiency.

[0003] Furthermore, some technicians have designed a transfer device for welding processing, by adding different automated manipulators to complete a single task, such as clamping the inner wear-resistant layer, clamping the outer wear-resistant layer, cooling the inner magnetic rotor in water, etc. Therefore, when completing the welding of an inner magnetic rotor, multiple clamping operations are often required, and the overall operation is more troublesome. It is also inconvenient to transfer internal magnetic rotors of different sizes, and the general performance is low. Moreover, this conventional clamping method cannot switch the clamping position, and thus the clamped position cannot be completely cooled and dried. For this reason, we propose a transfer device for the welding processing of the inner magnetic rotor of a magnetic pump. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1-15 , the present invention provides a technical solution:

[0043] A transfer device for welding a magnetic rotor in a magnetic pump includes a support frame 1 and a water tank 10. The support frame 1 and the water tank 10 are both common existing structures and will not be described in detail herein. The device also includes:

[0044] The fixed seat 11 is rotatably arranged just above the water tank 10. In this scheme, the fixed seat 11 adopts a regular hexagonal structure, on which a supporting structure for supporting the mounting frame 12 is evenly arranged. In the scheme, three mounting frames 12 are arranged, that is, three transfer stations are arranged. When the driving motor 22 rotates, the top is welded with the inner wear-resistant layer as the initial state. After the welding is completed, it does not directly rotate 120° to enter the next transfer station, but first rotates any angle between 30° and 90°. After the angle is rotated, it is the position where the welding machine welds the outer wear-resistant layer and the inner magnetic rotor. In the scheme, the angle is set to 60°, so that the inner magnetic rotor in the previous station just falls into the water tank 10 at the bottom for cooling, which is conducive to reducing the switching time. At the same time, the position of the fan 97 is also designed in this way, that is, when the inner magnetic rotor of the top station is welding the outer wear-resistant layer, the driving motor 22 rotates 60°, and the inner magnetic rotors of the other two stations are respectively at the water tank 10 and the fan 97 position, and then rotate 60 degrees here to complete the switching of the next station;

[0045] A mounting frame 12, wherein a plurality of mounting frames 12 are provided, and the plurality of mounting frames 12 are evenly arranged on the fixing seat 11, and are used for placing the inner magnetic rotor to be welded;

[0046] A welding switching unit 2, which is arranged on the support frame 1 and connected to a plurality of mounting frames 12, and is used to adjust the positions of the mounting frames 12 and the inner magnetic rotor to ensure normal welding of the inner wear-resistant layer and the outer wear-resistant layer;

The support frame 1 is provided with a manipulator 2 for clamping the outer wear-resistant layer. The manipulator 2 is located between the arc-shaped rack 1 25 and the arc-shaped rack 2 26. After the position of the mounting frame 12 and the inner magnetic rotor is adjusted, the outer wear-resistant layer is installed on the inner magnetic rotor. The manipulator 1 has the function of removing the inner magnetic rotor;

[0048] The fixing seat 11 is provided with a plurality of circular grooves 31, the locking member 3 comprises a spring 1 32 arranged in the circular groove 31, a locking ball 33 is arranged at the end of the spring 1 32, and a plurality of slots 34 respectively used in conjunction with the locking balls 33 are provided on the fixing shaft 23, and the number of the slots 34 is one more than the number of the locking balls 33, so that after the fixing shaft 23 rotates, the two locking balls 33 still have the slots 34 respectively matched with them, which is conducive to ensuring the state after the position adjustment;

[0049] Clamping plates 13, wherein the clamping plates 13 are provided in multiple groups, and each mounting frame 12 is provided with two groups of clamping plates 13;

[0050] The positioning switching unit 4 is arranged on the support frame 1 and connected with a plurality of clamping plates 13 to ensure that the inner magnetic rotors of different sizes can be clamped normally and the positions of the two sets of clamping plates 13 can be switched when entering water or drying.

[0051] The positioning switching unit 4 includes a controller and a battery arranged on the fixing seat 11, a synchronous unfolding member 5 is arranged on the mounting frame 12, and is used to synchronously adjust the distance between the two clamping plates 13 in each group of the two groups, and a switching component 6 is arranged on the mounting frame 12, and is used to realize the position switching between the two groups of clamping plates 13 while ensuring the normal operation of the synchronous unfolding member 5. The controller can be connected to the driving motor 22, the manipulator 1, the manipulator 2 and another control device of the welding machine by a wireless connection such as Bluetooth, so as to ensure the normal transportation work;

[0052] The synchronous unfolding member 5 includes an electric push rod 51 arranged on the mounting frame 12, a shift block 52 is arranged at the end of the electric push rod 51, a plurality of deflection rods 53 are rotatably arranged on the shift block 52, a plurality of sliding frames 54 are arranged on the mounting frame 12, a sliding block 55 is slidably arranged on each of the sliding frames 54, and the sliding blocks 55 are rotatably connected to the adjacent deflection rods 53 respectively;

[0053] The switching assembly 6 includes a fixed block 61 arranged between a plurality of sliding frames 54, and elastic members 7 are respectively arranged on the plurality of sliding blocks 55 for adjusting the position of the clamping plates 13. The fixed block 61 is provided with a fitting member 8 used in conjunction with the elastic member 7 for ensuring that there is always a group of clamping plates 13 in contact with the inner magnetic rotor. The support frame 1 is provided with an extrusion type driving member 9 for driving the clamping plates 13 to adjust when entering water or drying.

[0054] The elastic member 7 includes a displacement column 71 slidably disposed on the sliding block 55, both ends of the displacement column 71 extend to the outside of the sliding block 55, and the clamping plate 13 is disposed on the side of the displacement column 71 away from the fixed block 61, and a second spring 72 is sleeved on the outside of the displacement column 71;

[0055] The fitting member 8 includes a rotating shaft 81 rotatably arranged at the center of the fixed block 61, a shift slide 82 is arranged on the rotating shaft 81, arc blocks 83 are slidably arranged on both sides of the shift slide 82, and a special-shaped block 84 used in conjunction with the arc block 83 is arranged on the side of the shift column 71 close to the arc block 83, a connecting rod 85 is arranged on the sliding block 55, and a guide column 86 is rotatably arranged at the end of the connecting rod 85, and an arc groove 87 used in conjunction with the guide column 86 is opened on the arc block 83. When the sliding block 55 is displaced, it can drive the arc block 83 to shift synchronously to ensure the spacing between the arc block 83 and the special-shaped block 84. In the initial state, the arc block 83 first squeezes the special-shaped block 84 on one group of clamps 13, and disengages from the special-shaped block 84 on the other group of clamps 13;

[0056] The extrusion drive member 9 includes a transmission gear 91 arranged at one end of the rotating shaft 81 away from the shift slide 82, a transmission rack 92 is slidably arranged on the fixed block 61 and is used in conjunction with the transmission gear 91, a mounting cavity 93 is arranged on the fixed block 61, a piston rod 94 is movably arranged in the mounting cavity 93, the end of the piston rod 94 is connected to the transmission rack 92, a spring 95 in contact with the piston rod 94 is arranged in the mounting cavity 93, an extrusion airbag 96 is arranged on the fixed seat 11, the mounting cavity 93 and the extrusion airbag 96 are connected by a pipeline, a fan 97 is arranged on the support frame 1, and a water entry extrusion block 98 and a drying extrusion block 99 are arranged on the support frame 1.

[0057] When in use, the top is welded with the inner wear-resistant layer as the initial state, the device firmly supports the entire system through the support frame 1, the water tank 10 is located below the support frame 1 for cooling, the fixed seat 11 is designed with a regular hexagonal structure, and is connected to the support frame 1 through the rotating shaft 21 just above the water tank 10, and the rotation is controlled by the driving motor 22, and the mounting frame 12 is evenly arranged on the fixed seat 11 for placing the inner magnetic rotor to be welded;

[0058] The inner wear-resistant layer is placed on the first inner magnetic rotor through the robot 1, and the driving motor 22 rotates to drive the rotating shaft 21 and the fixed seat 11 to rotate, and the welding machine rotates to perform welding. After welding is completed, the driving motor 22 is started again and rotated 60°. During rotation, the fixed gear 24 cooperates with the arc-shaped rack 1 25 to achieve precise position adjustment of the mounting frame 12 and the first inner magnetic rotor, and the first inner magnetic rotor is adjusted to a position close to the robot 2, and the outer wear-resistant layer is placed by the robot 2, and welded again through the welding machine. After welding is completed, the driving motor 22 is started again and rotated 60°. At this time, the fixed gear 24 cooperates with the arc-shaped rack 2 26 to reset the mounting frame 12 and the first inner magnetic rotor. At the same time, the second inner magnetic rotor rotates to the top for inner The wear-resistant layer is welded, and the driving motor 22 is started again and rotated 60°. At this time, the first inner magnetic rotor rotates to the bottom water tank 10. In this process, the extrusion airbag 96 is squeezed by the water-entering extrusion block 98, and the piston rod 94 drives the transmission rack 92 to shift, and the transmission rack 92 drives the transmission gear 91 and the rotating shaft 81 to rotate, thereby driving the shift slide 82 at the other end and the top arc block 83 to rotate, so that the arc block 83 first squeezes the special-shaped block 84 on one group of splints 13, and then disengages from the special-shaped block 84 on the other group of splints 13, realizing the switching of the two groups of splints 13. When the water-entering extrusion block 98 disengages, it resets to the initial state, that is, the other group of splints 13 is clamped. Similarly, it can be seen that the same is true when the fan 97 is in position, which will not be repeated;

[0059] When the size of the inner magnetic rotor is changed to another batch, all the work of the previous batch is completed, and the control parameters of each structure are adjusted through the controller and the control device. The specific adjustment is as follows: start the electric push rod 51 to drive the shift block 52 and the deflection rod 53 to work, and the deflection rod 53 will drive the sliding block 55 to shift, so as to realize the size adjustment of the splint 13. When adjusting the size, the arc block 83 contacts with the guide column 86 on one of the sliding blocks 55, so that the arc block 83 slides on the shift slide 82, and the guide column 86 slides on the shift slide 82, so as to realize synchronous adjustment. When docking is required, because the adjustment of the sliding block 55 is synchronous, when the arc block 83 rotates, the arc groove 87 thereon can still coincide with the guide column 86 on the other sliding block 55. In subsequent work, the transmission of the transmission gear 91, the transmission rack 92 and the piston rod 94 is used to realize the switching of the submerged and dry states of the splint 13.

[0060] Example 2: Please refer to Fig.16 , the present invention provides a technical solution:

[0061] Different from Example 1, the side of the water extrusion block 98 and the dry extrusion block 99 that first contacts the extrusion airbag 96 is chamfered. The chamfer allows the extrusion airbag 96 to have a certain amount of pre-contact when contacting the water extrusion block 98 and the dry extrusion block 99, thereby completely squeezing the extrusion airbag 96, which helps to reduce the pressure of contact collision and avoid damage to the extrusion airbag 96.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
