[0002] The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The air-conditioning compressor is generally installed in the outdoor unit. The air-conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid.

[0003] In the manufacturing process of compressor housing, welding of the upper and lower housings is one of the key manufacturing steps. However, many manufacturers currently use traditional manual welding methods. The defects of this method are obvious: it relies on workers to manually align the upper and lower housings, which is not only inefficient but also difficult to ensure accuracy. In addition, during the welding process, workers are required to manually rotate the housing so that the welding wheel can perform continuous welding operations along the weld. This operation method not only increases the burden on workers, but is also easily interfered by human factors, such as differences in skill levels, fatigue, and distraction, resulting in unstable welding quality, uneven welds, and even loose welding.

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] The following describes the air-conditioning compressor housing welding device according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, the air-conditioning compressor housing welding device of the embodiment of the utility model may include a base 1, a fixed seat 2, a lower fixed cylinder 3, a rotating seat 4, an annular cavity 5, a movable column 6, a lifting frame 7, a welding assembly 8, an upper fixed cylinder 9 and a driving assembly 10.

[0031] Among them, the base 1 is set on the ground, the fixed seat 2 is fixedly connected to the top center of the base 1, a driving groove 21 is opened on the surface of the fixed seat 2, and teeth 22 are set on the inner wall of the driving groove 21, and the lower fixed tube 3 is fixedly connected to the top center of the fixed seat 2.

[0032] The rotating seat 4 is fixedly connected to the top of the base 1 and is located outside the fixed seat 2 . The distance between the rotating seat 4 and the lower fixed cylinder 3 forms an annular cavity 5 .

[0033] The movable column 6 is slidably connected to the top of the rotating seat 4, the lifting frame 7 and the welding assembly 8 are respectively arranged on the surface of the movable column 6, and are arranged up and down, the upper fixed cylinder 9 is rotatably connected to the bottom of one end of the lifting frame 7, and is arranged coaxially with the lower fixed cylinder 3, the inner walls of the lower fixed cylinder 3 and the inner walls of the upper fixed cylinder 9 are respectively fixedly connected with disc-shaped electromagnets 11, and the surface of the disc-shaped electromagnet 11 located inside the lower fixed cylinder 3 is provided with a positioning column 100.

[0034] The driving assembly 10 is disposed inside the moving column 6 , one end of the driving assembly 10 is connected to the lifting frame 7 and one end of the welding assembly 8 respectively, and the other end of the driving assembly 10 penetrates into the annular cavity 5 and meshes with the teeth 22 .

[0035] It should be noted that the welding assembly 8, driving assembly 10 and disc-shaped electromagnet 11 described in this embodiment are electrically connected to the external controller respectively, and are uniformly controlled by the external controller, so the data is accurate and the performance is stable.

[0036] It should also be noted that the interior of the lower fixed cylinder 3 and the interior of the upper fixed cylinder 9 are respectively adapted to the outer dimensions of the compressor lower shell and the compressor upper shell. The compressor lower shell is placed inside the lower fixed cylinder 3, and the compressor upper shell is placed upside down inside the upper fixed cylinder 9. One end of the compressor lower shell and one end of the compressor upper shell protrude from the outside of the lower fixed cylinder 3 and the outside of the upper fixed cylinder 9 respectively, and their welds correspond to the positions of the welding components 8 and are at the same height.

[0037] It can be understood that one end of the positioning column 100 is located inside the upper shell of the compressor and is fixed to the inner wall of the upper shell of the compressor. The position of the upper shell of the compressor is limited by the positioning column 100. After the upper shell of the compressor is limited, it cooperates with the disc-shaped electromagnet 11 to synchronously drive the upper fixed cylinder 9 to remain in position, so that one end of the lifting frame 7 can be rotatably connected to the top of the upper fixed cylinder 9.

[0038] It can also be understood that, in order to prevent the upper fixed cylinder 9 from self-rotating during lifting, a damping ring is further provided at the connection between the surface of the upper fixed cylinder 9 and the bottom of the lifting frame 7 .

[0039] Specifically, when in use, the compressor upper shell and the compressor lower shell are respectively installed on the inner wall of the upper fixed cylinder 9 and inside the upper fixed cylinder 9, and then the disc-shaped electromagnet 11 is energized and operated by an external controller to magnetically fix the compressor upper shell and the compressor lower shell.

[0040] After the fixation is completed, the driving component 10 is controlled to rotate forward through the external controller. The forward rotation of the driving component 10 drives the lifting frame 7 and the upper shell of the compressor to move downward. At the same time, the forward rotation of the driving component 10 also drives the welding component 8 to move toward the weld. When the upper shell of the compressor contacts the lower shell of the compressor, one end of the welding component 8 synchronously contacts the weld.

[0041] Then, the external controller controls the driving assembly 10 to reverse and the welding assembly 8 to run. The driving assembly 10 reverses and drives the movable column 6 to move on the top of the rotating seat 4 with the fixed cylinder 3 as the center. The movement of the movable column 6 synchronously drives the lifting frame 7 and the welding assembly 8 to move. When the lifting frame 7 moves, one end of the lifting frame 7 rotates with the top of the fixed cylinder 9 as the center. The welding assembly 8 moves to perform welding operations around the weld.

[0042] After the movable cylinder 6 moves one circle, the external controller controls the welding assembly 8, the driving assembly 10 and the disc-shaped electromagnet 11 inside the upper fixed cylinder 9 to stop running respectively, and then continues to control the driving assembly 10 to rotate forward, and links the upper fixed cylinder 9 to separate from the lower fixed cylinder 3. After the upper fixed cylinder 9 is reset, the external controller controls the driving assembly 10 to stop running, and then separates the positioning column cylinder and the positioning clamping column 100 on the upper shell of the compressor, and then takes the welded compressor shell as a whole out of the lower fixed cylinder 3.

[0043] The device can realize automatic docking between the compressor upper shell and the compressor lower shell and between the welding component 8 and the weld, and after the docking is completed, it can automatically drive the welding component 8 to perform welding operations around the weld, effectively improving production efficiency and welding quality.

[0044] In one embodiment of the present invention, Figure 2 As shown, a negative pressure suction port 12 is respectively provided on the inner wall of the lower fixed cylinder 3 and the inner wall of the upper fixed cylinder 9, and an air pipe joint 13 is respectively threadedly connected to the surface of the lower fixed cylinder 3 and the surface of the upper fixed cylinder 9, and an air flow channel is respectively provided inside the lower fixed cylinder 3 and the upper fixed cylinder 9, and both ends of the air flow channel are respectively connected to the negative pressure suction port 12 and the air pipe joint 13.

[0045] It should be noted that the disc-shaped electromagnet 11 described in this embodiment is used to magnetically fix the end of the compressor upper shell and the compressor lower shell away from the weld, and the negative pressure suction port 12 is used to negatively adsorb and fix the end of the compressor upper shell and the compressor lower shell close to the weld, so as to ensure the stability of the material and improve the welding quality.

[0046] It should also be noted that the air pipe connector 13 described in this embodiment is connected to an external negative pressure device, which extracts air from the air flow channel so that the negative pressure suction port 12 is in a negative pressure state, thereby tightly adsorbing the compressor housing and fixing the compressor housing.

[0047] It is understandable that, in order to facilitate unified control, the external negative pressure device is electrically connected to the external controller.

[0048] In one embodiment of the present invention, Figure 3 As shown, a limit assembly 60 is disposed at the bottom of the movable column 6 , and the limit assembly 60 may include an L-shaped slide frame 61 and a ring frame 62 .

[0049] Among them, the L-shaped slide 61 is slidably connected to the top of the rotating seat 4, the movable column 6 is fixedly connected to the top of the L-shaped slide 61, and the arc-shaped limit block 611 and the limit ring groove 41 are respectively arranged at the positions corresponding to the surface of the L-shaped slide 61 and the surface of the rotating seat 4. The arc-shaped limit block 611 is slidably connected to the inner wall of the limit ring groove 41, and the top of the rotating seat 4 is fixedly connected with an annular electromagnet 42, and is magnetically fixed to the bottom of the L-shaped slide 61, the ring frame 62 is sleeved on the outside of the lower fixed cylinder 3, and is slidably connected to the surface of the lower fixed cylinder 3, and one end of the ring frame 62 is connected to one end of the L-shaped slide 61.

[0050] It should be noted that the ring frame 62 described in this embodiment is integrally formed on the surface of the L-shaped slide 61. The limit assembly 60 can improve the stability of the sliding of the movable column 6. The annular electromagnet 42 is used to fix the movable column 6 after the movable column 6 stops moving to prevent it from displacement and reduce the gear load, thereby achieving good use effect.

[0051] It should also be noted that the top of the annular electromagnet 42 described in this embodiment is in the same plane as the top of the rotating seat 4, which is convenient for the L-shaped slide 61 to slide.

[0052] It is understandable that, in order to facilitate unified control, the annular electromagnet 42 is electrically connected to the external controller.

[0053] In one embodiment of the present invention, Figure 4 As shown, the driving assembly 10 may include a dual-axis motor 101 , an encoder 102 , an upper driving rod 103 , a one-way transmission 104 , an upper bidirectional lead screw segment 105 , a worm gear 106 , a lower driving rod 107 and a driving gear 108 .

[0054] The dual-axis motor 101 is fixedly connected to the inner wall of the moving column 6, the encoder 102 is fixedly connected to the surface of the dual-axis motor 101, the upper driving rod 103 is rotatably connected to the inner wall of the moving column 6 and is located on the top side of the dual-axis motor 101, the lower driving rod 107 is rotatably connected to the inner wall of the moving column 6 and is located on the bottom side of the dual-axis motor 101, one end of the upper driving rod 103 and one end of the lower driving rod 107 are respectively connected to one end of the dual-axis motor 101 through a one-way transmission device 104, and the two sets of one-way transmission devices 104 have opposite transmission directions, and the lower driving rod 107 is connected to the inner wall of the moving column 6 and is located on the bottom side of the dual-axis motor 101. One end of the rod 107 passes through the annular cavity 5 and is fixedly connected to a driving gear 108. One end of the driving gear 108 is located inside the driving groove 21 and meshes with the teeth 22. The worm gear 106 is fixedly connected to the surface of the upper driving rod 103. The surface of the upper driving rod 103 is divided into an upper bidirectional screw segment 105 and a lower smooth segment with the worm gear 106 as the interface. The lifting frame 7 is slidably connected to the outer surface of the moving column 6. One end of the lifting frame 7 passes through the interior of the moving column 6 and is threadedly connected to the outer surface of the upper bidirectional screw segment 105.

[0055] It should be noted that the encoder 102 and the dual-axis motor 101 described in this embodiment are electrically connected to the external controller respectively. The dual-axis motor 101 serves as a power source, and the encoder 102 is used to detect the number of rotations of the dual-axis motor 101 in real time, and send the number of rotations data to the external controller. The external controller determines the positions of the lifting frame 7 and the shifting seat 84 based on the number of rotations data, and further determines the positions of the upper compressor housing and the welding wheel 85.

[0056] It should also be noted that the one-way transmission 104 described in this embodiment is a prior art and will not be described in detail herein. The one-way transmission 104 connected to the upper drive rod 103 can drive the upper drive rod 103 to rotate only when the dual-axis motor 101 rotates forward, and the one-way transmission 104 connected to the lower drive rod 107 can drive the lower drive rod 107 to rotate only when the dual-axis motor 101 rotates reversely.

[0057] Specifically, the external controller controls the dual-axis motor 101 to be powered on and run according to the instructions. The dual-axis motor 101 runs and synchronously drives the two sets of output ends to rotate. In the forward rotation case, the rotation of the output end of the dual-axis motor 101 can only drive the one-way transmission 104 connected to the upper drive rod 103 to run. The one-way transmission 104 runs and synchronously drives the upper drive rod 103 to rotate. The rotation of the upper drive rod 103 synchronously drives the upper bidirectional lead screw segment 105 and the worm gear 106 to rotate. The rotation of the upper bidirectional lead screw segment 105 synchronously drives the lifting frame 7 to reciprocate up and down. The worm gear 106 rotates synchronously with the belt The worm part 82 in the movable transverse transmission rod 81 rotates, and the rotation of the worm part 82 synchronously drives the bidirectional screw part 83 to rotate, and the rotation of the bidirectional screw part 83 synchronously drives the moving seat 84 and the welding wheel 85 to reciprocate left and right. The lifting frame 7 moves downward and synchronously drives the upper compression shell to move to the side of the lower compressor shell, and the moving seat 84 moves to the right and synchronously drives the welding wheel 85 to move to the upper compression shell and the lower compressor shell. When the upper compression shell contacts the lower compressor shell, the dual-axis motor 101 stops running. At this time, one end of the welding wheel 85 abuts against the weld, which is convenient for subsequent welding operations.

[0058] The external controller controls the dual-axis motor 101 to reverse. In the reverse state, the rotation of the output end of the dual-axis motor 101 can only drive the one-way transmission 104 connected to the lower drive rod 107 to operate. The operation of the one-way transmission 104 synchronously drives the lower drive rod 107 to rotate. The rotation of the lower drive rod 107 synchronously drives the driving gear 108 to rotate. The driving gear 108 rotates and meshes with the teeth 22 and moves along the surface of the teeth 22. The movement of the driving gear 108 synchronously drives the moving column 6, the limiting assembly 60, the lifting frame 7 and the welding assembly 8 to move. The welding wheel 85 in the welding assembly 8 performs welding operations on the weld during the movement.

[0059] In one embodiment of the present invention, Figure 4 As shown, the welding assembly 8 may include a transverse transmission rod 81, a shifting seat 84 and a welding wheel 85.

[0060] Among them, the transverse transmission rod 81 is rotatably connected to the surface of the moving column 6;

[0061] A worm portion 82 is provided on one end surface of the transverse transmission rod 81 that passes through the interior of the moving column 6. The worm portion 82 is located on one side of the worm wheel 106 and meshes with the worm wheel 106. A bidirectional screw portion 83 is provided on one end surface of the transverse transmission rod 81 that is located outside the moving column 6. The moving seat 84 is threadedly connected to the outer surface of the bidirectional screw portion 83 and is slidably connected to the surface of the moving column 6. The welding wheel 85 is provided on the surface of the moving seat 84.

[0062] It should be noted that the surfaces of the movable column 6 described in the embodiment are respectively provided with sliding grooves for facilitating the sliding of one end of the lifting frame 7 and one end of the moving seat 84 .

[0063] Specifically, the rotation of the worm wheel 106 synchronously drives the worm portion 82 in the transverse transmission rod 81 to rotate, the rotation of the worm portion 82 synchronously drives the bidirectional screw portion 83 to rotate, the rotation of the bidirectional screw portion 83 synchronously drives the moving seat 84 and the welding wheel 85 to reciprocate left and right, the lifting frame 7 moves downward and synchronously drives the upper compression shell to move toward the side of the lower compressor shell, the moving seat 84 moves to the right and synchronously drives the welding wheel 85 to move toward the upper compression shell and the lower compressor shell. When the upper compression shell contacts the lower compressor shell, the dual-axis motor 101 stops running. At this time, one end of the welding wheel 85 abuts against the weld, which is convenient for subsequent welding operations.

[0064] In one embodiment of the present invention, Figure 4 As shown, the moving speed of the shift seat 84 on the outer surface of the bidirectional screw rod portion 83 is different from the moving speed of the lifting frame 7 on the outer surface of the upper bidirectional screw rod segment 105.

[0065] It should be noted that the moving speeds described in the embodiments are different, so that the upper shell and the welding wheel 85 can reach the set position and contact each other at the same time, which is simple to operate and easy to use.

[0066] In one embodiment of the present invention, Figure 1 As shown, the positioning column 100 is located inside a mounting hole opened on the surface of the compressor lower shell, and a positioning column barrel that is clamped with one end of the positioning column 100 is threadedly connected to the inner wall of the compressor upper shell.

[0067] It should be noted that the positioning column 100 described in this embodiment is located on the inner side of the mounting hole opened on the surface of the lower shell of the compressor, which does not affect the placement and use of the lower shell of the compressor. A positioning column barrel that is clamped with one end of the positioning column 100 is threadedly connected to the inner wall of the upper shell of the compressor. When one end of the positioning column 100 is connected and clamped to the positioning column barrel, the position of the upper cylinder can be limited to prevent it from rotating, thereby facilitating the welding wheel 85 to perform welding operations around the weld.

[0068] It can be understood that the positioning column is also threadedly connected to the inner wall of the mounting hole opened on the surface of the compressor upper shell, which will not affect the compressor upper shell. If the positions of the two sets of mounting holes are asymmetrical, the positioning column 100 can be I-shaped or N-shaped, and the shape of the positioning column 100 can be changed according to the actual installation position.

[0069] It can also be understood that the surface of the positioning column 100 and the inner wall of the positioning column tube are respectively provided with a straight key and a straight key groove, and the design of the straight key and the straight key groove is convenient for connection and clamping and limiting, and has a good use effect.

[0070] In summary, the air-conditioning compressor housing welding device of the embodiment of the utility model can realize automatic docking between the compressor upper housing and the compression lower housing and between the welding wheel 85 and the weld, and after the docking is completed, it can automatically drive the welding wheel 85 to perform welding operations around the weld, effectively improving production efficiency and welding quality.
