[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A welding device for pump body processing includes a base 1, a fixing frame 2 is fixedly installed on the top side of the base 1, and a support part 4 is provided on the top of the base 1 through a driving member 3. The driving member 3 is used to drive the support part 4 to move. A fixing component 5 and a rotating member 6 are provided in the support part 4. The fixing component 5 is used to fix the pump body, and the rotating member 6 is used to cooperate with the fixing component 5 to drive the pump body to rotate.

[0022] Furthermore, the driving member 3 includes a slide rail 31 and a cylinder 32, the slide rail 31 is fixedly installed on the top of the base 1, the supporting part 4 includes a fixed seat 41 and a movable seat 42, the fixed seat 41 is fixedly installed on the top of the base 1, the movable seat 42 is slidably connected to the base 1 through the slide rail 31, and the shaft end of the cylinder 32 is fixedly connected to the movable seat 42.

[0023] Furthermore, the fixing assembly 5 includes a rotating shaft 51 rotatably connected to the side of the fixing seat 41, and a movable rod 52 is slidably connected inside the rotating shaft 51. The inner wall of the rotating shaft 51 and the outer periphery of the movable rod 52 are respectively provided with a limiting groove and a limiting column 54, and the limiting groove and the limiting column 54 are slidably connected.

[0024] In more detail, the fixing assembly 5 also includes a connecting seat 55, a connecting rod 56 and a support plate 57. The connecting seat 55 is arranged on the periphery of the rotating shaft 51 and the movable rod 52. The two ends of the connecting rod 56 are respectively rotatably connected to the connecting seat 55 and the support plate 57. The support plate 57 is connected to the connecting seat 55 at both ends through the connecting rod 56.

[0025] In general, the fixing assembly 5 further includes a first spring 53 , which is sleeved on the periphery of the movable rod 52 , and the two ends of the first spring 53 are fixedly connected to the side surfaces of the rotating shaft 51 and the connecting seat 55 , respectively.

[0026] It should be added that in the prior art, the middle bearing of the pump design is directly supported on the pump body. The position of the bearing seat and the inlet and outlet pipes of the pump body need to be welded. Since these parts are provided with through holes, a plurality of support plates 57 are used to support the through holes and thus achieve the function of fixing the pump body.

[0027] It is worth mentioning that under the elastic support of the first spring 53, the connecting seat 55 located on the axial end of the connecting rod 56 slides toward the end away from the rotating shaft, and then one end of the connecting rod 56 on both sides rotates, while the other end pulls the support plate 57 down to facilitate insertion into the through hole.

[0028] In other words, the rotating member 6 includes a support frame 61, and the top of the movable seat 42 is rotatably connected to a key shaft 62 through the support frame 61. A motor 63 is fixedly installed on the side of the support frame 61, and the shaft end of the motor 63 is fixedly connected to the key shaft 62. A key slot is provided on the side of the connecting seat 55; the key shaft 62 is connected to the connecting seat 55 and is snapped into the key slot.

[0029] In actual operation, the movable seat 42 drives the key shaft 62 and the pump body to move under the action of the cylinder 32 and the slide rail 31. When the movable seat 42 reaches the appropriate position, the through hole of the pump body is inserted into the support plate 57.

[0030] Among them, because the key shaft 62 conflicts with the connecting seat 55, the movable rod 52 drives the connecting seat 55 to move, and then the connecting seat 55 drives the connecting rods 56 on both sides to rotate at the same time as the distance between the connecting seat 55 and the other connecting seat 55 is reduced. Because the connecting rods 56 on both sides are relatively arranged, several support plates 57 are driven to support the pump body.

[0031] Finally, a pair of guide rods 21 are slidably connected to the side of one of the fixing frames 2, a grinding plate 22 is fixedly installed on the guide rods 21, and a second spring 23 is sleeved on the guide rods 21, and the two ends of the second spring 23 are respectively fixedly connected to the grinding plate 22 and the side of the fixing frame 2; a welding gun 7 is fixedly installed on the top of the other fixing frame 2.

[0032] Specifically, the parts of the pump body that need to be welded are polished by the polishing plate 22, and after polishing, the welding is performed using the welding gun 7 to ensure good welding quality;

[0033] In specific operations, the fixing frame 2 and the base 1 can be connected in a sliding manner and can be fixed by locking bolts or latches, etc., which makes it easy to change the positions of the welding gun 7 and the grinding plate 22.

[0034] Working mode: When working, the pump body is placed in the mounting groove on the top of the movable seat 42, and the cylinder 32 cooperates with the slide rail 31 to drive the movable seat 42 to move. When the movable seat 42 reaches the appropriate position, the through groove of the pump body will be inserted into the movable rod 52, the key shaft 62 will contact the connecting seat 55, and the key shaft 62 will be inserted into the key groove;

[0035] Then, the key shaft 62 continuously contacts the connecting seat 55, and the connecting seat 55 slides toward one side of the rotating shaft 51. Then, one end of the connecting rods 56 on both sides rotates due to the pressure. Then, the other ends of the connecting rods 56 on both sides pull the support plate 57 up and support the through groove of the pump body, thereby fixing the pump body.

[0036] Finally, the motor 63 drives the key shaft 62 to rotate, and the key shaft 62 drives the rotating shaft 51 to drive the pump body to rotate. The pump body is first polished by the polishing plate 22 and then welded by the welding gun 7.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
