[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] refer to Figure 1-3 , a water meter case 6 center ring press welding integrated equipment, comprising: a machine 1; a press ring mechanism 2, having a bottom mold 21 installed on the machine 1 for placing the water meter case 6, and a driving component 22 located above the bottom mold 21 for pressing the center ring; a positioning component 3, installed on the machine 1 and spaced from the bottom mold 21, for positioning and rotating the water meter case 6; a clamping and moving component 4, having a linear module 41 installed on the machine 1 and located on one side of the bottom mold 21 and the positioning component 3, and a clamping module 42 installed on the linear module 41, the clamping module 42 takes out the water meter case 6 on the bottom mold 21 and drives it to the positioning component 3 through the linear module 41 for positioning; a welding component 5, installed on the machine 1 and located on one side of the positioning component 3, having a welder 52 for welding the center ring and an adjusting frame 51 for fixing the welder 52.

[0036] It can be understood that the process of placing the water meter shell 6 on the bottom mold 21 can be done manually or by installing a robot for automatic material discharge. The driving component 22 is a component that can move downward to apply downward pressure to the middle circle in the water meter shell 6, thereby pressing the middle circle down to the exact position in the water meter shell 6. The positioning component 3 plays a role in positioning and fixing the water meter shell 6, and a clamp or a mold can be used. Since the outer ring of the middle ring is circular and contacts the inner wall of the water meter shell 6, the positioning component 3 needs to have the function of driving the water meter shell 6 to rotate, and then, welding is performed along the outer ring edge of the middle ring during welding. The linear module 41 can adopt: a ball screw and a linear guide rail combination structure, a cylinder or hydraulic matching linear guide rail structure, a linear motor structure, a gear rack structure, etc. The clamping module 42 needs to have a clamping function and also needs the function of moving up and down. The adjustment frame 51 can adjust the upper and lower positions, left and right positions, and even the rotation angle of the welder 52. A robotic arm can be used.

[0037] With such a configuration, when working, the water meter case 6 with the middle ring is put on the bottom mold 21, and the middle ring is pressed down by the driving component 22. After the pressing is completed, the clamping component clamps the pressed water meter case 6 and takes it out from the bottom mold 21, and then drives it to move above the positioning component 3 through the linear module 41, and puts it into the positioning component 3, and the positioning component 3 then clamps the water meter case 6. Finally, the welder 52 is extended into the water meter case 6 by adjusting the frame, that is, the place where the middle ring and the inner wall of the water meter case 6 are in contact. The water meter case 6 is driven to rotate by the positioning component 3 to cooperate with the welder 52 for welding. The utility model integrates the pressing ring and welding to achieve fully automatic pressure welding.

[0038] Optionally, in some embodiments, the ring pressing mechanism 2 further includes a frame mounted on the machine 1, the frame having a fixed plate 23 located above the positioning assembly 3, and the driving assembly 22 is mounted on the fixed plate 23. Further, the driving assembly 22 includes: a telescopic driver 221, mounted on the fixed plate 23; a pressure head 222, mounted at the output end of the telescopic driver 221 and corresponding to the positioning assembly 3; the telescopic device drives the pressure head 222 to move downward to press the middle ring in the water meter shell 6 on the bottom mold 21, and moves upward to reset after the pressing is completed.

[0039] It is understandable that, since the driving assembly 22 needs to move downward and upward, the driving assembly 22 can be installed at intervals through the setting of the fixing plate 23. The fixing plate 23 can be installed through a vertically arranged connecting rod. The telescopic drive 221 can be a cylinder, a hydraulic cylinder, an electric rod and other devices. The output end of the telescopic drive 221 can be arranged vertically downward. The size of the pressure head 222 can extend from the top opening of the water meter housing 6 into the inside of the water meter housing 6 and press on the middle circle.

[0040] With such arrangement, when the water meter housing 6 with the middle ring is sleeved on the bottom mold 21, the telescopic driver 221 drives the pressure head 222 to move downward and press on the middle ring. After the pressing is completed, the telescopic driver 221 retracts and drives the pressure head 222 to move upward and reset.

[0041] In some embodiments, the positioning assembly 3 includes: a rotator 31, installed on the machine 1; a fixer 32, installed on the rotator 31, for fixing the water meter housing 6; the rotator 31 drives the fixer 32 to rotate and then drives the water meter housing 6 to rotate.

[0042] It is understandable that the rotator 31 may be a motor, a rotary cylinder, etc. The fixer 32 may be a pneumatic clamp, a motor clamp, a mechanical spring clamp or other clamping devices.

[0043] With such arrangement, when the water meter housing 6 is placed on the holder 32, the holder 32 clamps the water meter housing 6. During welding, the holder 32 is driven to rotate by the rotator 31, thereby driving the water meter housing 6 to rotate.

[0044] Optionally, in some embodiments, the clamping module 42 includes: a lifter 421, installed on the linear module 41; a clamper 422, installed on the lifter 421, for clamping the water meter case 6; the lifter 421 drives the clamper 422 and then drives the water meter case 6 to move up and down.

[0045] It is understandable that whether the water meter housing 6 is taken out from the bottom mold 21 or put into the positioning assembly 3, the clamping module 42 needs to have the function of moving up and down, so the lifter 421 is installed for use. The lifter 421 can adopt a structure such as a telescopic cylinder, an electric cylinder, a linear motor, a ball screw and a linear guide rail combination. The clamper 422 can adopt: pneumatic clamps, motor clamps, mechanical spring clamps, etc.

[0046] With such arrangement, the water meter housing 6 can be clamped by the clamp 422 , and in conjunction with the lifter 421 , the water meter housing 6 can be moved upward to be taken out of the bottom mold 21 and moved downward to be placed in the positioning assembly 3 .

[0047] Optionally, in some embodiments, the adjustment frame 51 includes: a transverse driving module 511, which is installed on the machine table 1 and has a driving direction perpendicular to the driving direction of the linear module 41; and a longitudinal driving module 512, which is installed on the transverse driving module 511 and is used to install the welder 52. Furthermore, the welding assembly 5 also includes a welding host 53, which is connected to the welder 52.

[0048] It is understandable that the transverse drive module 511 and the longitudinal drive module 512 can be assembled in pairs by using: a ball screw and a linear guide combination structure, a cylinder or hydraulic matching linear guide structure, a linear motor structure, a gear rack structure, etc. The welder 52 can be a laser welder or a welding head for clamping welding wire. The welding host 53 is a control device for controlling welding, which is a prior art.

[0049] In this way, the horizontal position and the height position of the welder 52 can be adjusted by the transverse driving module 511 and the longitudinal driving module 512, so that the welder 52 can be automatically inserted into the water meter housing 6.

[0050] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
