Technical Field

[0001] This utility model relates to the technical field of welding equipment, specifically to a welding equipment for an oil stabilizing ring on a compressor housing. Background Technology

[0002] The compressor housing and the oil stabilizing ring are generally fixed by welding. For example, the patent document with publication number CN221610190U discloses "compressor, refrigeration equipment and oil stabilizing ring", which specifically includes "the oil stabilizing ring can be made of metal to give it a certain structural strength. The outer periphery of the oil stabilizing ring can be welded to the inner wall of the housing to improve the assembly strength of the oil stabilizing ring".

[0003] In the traditional welding process for the oil stabilizing ring, it is necessary to drill holes and fill them with solder at the corresponding welding positions on the compressor housing. This welding method has the disadvantages of relatively high cost and low welding efficiency.

[0004] Therefore, further improvements are needed. Utility Model Content

Above the inner positioning core is a positioning upper pressure head for driving the oil stabilizing ring into the inner side of the compressor housing and abutting against the inner positioning core. The upper end of the inner positioning core forms a welding area corresponding to the position on the outer side of the compressor housing. The outer side of the inner positioning core is provided with a laser welder for welding the compressor housing and the oil stabilizing ring.

[0007] As a specific embodiment, an upper pressure head cylinder is connected to the upper side of the positioning upper pressure head, and the upper pressure head cylinder can drive the positioning upper pressure head to move back and forth vertically.

[0008] As a specific embodiment, the outer side of the inner positioning core is provided with a nozzle for blowing protective gas into the welding area at a position adjacent to the welding area.

[0009] As a specific embodiment, the upper side of the inner positioning core is provided with a positioning protrusion for circumferential positioning of the oil stabilizing ring.

The outer positioning core is connected to a bracket, and the bracket is connected and fixed to the outer positioning core and the turntable respectively.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1-5 The compressor housing oil stabilizing ring welding equipment includes an inner positioning core 2 for passing through the compressor housing 1 axially and limiting the compressor housing 1. Above the inner positioning core 2 is a positioning upper pressure head 4 for driving the oil stabilizing ring 3 into the inner side of the compressor housing 1 and abutting against the inner positioning core 2. The inner positioning core 2 and the positioning upper pressure head 4 cooperate to enable the compressor housing 1 and the oil stabilizing ring 3 to be positioned and fitted according to the preset position, thereby improving the welding accuracy.

[0022] The upper end of the inner positioning core 2 forms a welding area corresponding to the outer side of the compressor housing 1. The outer side of the inner positioning core 2 is provided with a laser welder 5 for welding the compressor housing 1 and the oil stabilizing ring 3. The laser welder 5 can perform local high-temperature melting and fusion of the compressor housing 1 and the oil stabilizing ring 3 in the welding area, eliminating the need for drilling and filling the compressor housing 1 with solder, which reduces processing costs and improves welding efficiency.

[0023] The positioning pressure head 4 can pick up and release the oil stabilizing ring 3 by electromagnetic attraction or negative pressure attraction. This will be understood by those skilled in the art.

[0024] Furthermore, an upper pressure head cylinder 41 is connected to the upper side of the positioning upper pressure head 4. The upper pressure head cylinder 41 can drive the positioning upper pressure head 4 to move back and forth vertically, making it convenient for users to control the movement state of the positioning upper pressure head 4.

[0025] Furthermore, the outer side of the inner positioning core 2 is provided with a nozzle 6 for blowing protective gas into the welding area at a position adjacent to the welding area. The protective gas is preferably nitrogen. Nitrogen can displace the air near the welding area, preventing oxidation at the welding position. Moreover, the nitrogen gas flow can carry away the heat generated by welding, allowing the welding position to cool down faster and reducing the chance of material surface defects.

[0026] Furthermore, the upper side of the inner positioning core 2 is provided with a positioning protrusion 21 for circumferential positioning of the oil stabilizing ring 3, which improves the positioning accuracy of the oil stabilizing ring 3 and makes the welding accuracy between the oil stabilizing ring 3 and the compressor housing 1 higher.

[0027] Furthermore, a turntable 8 is fixedly connected to the bottom of the inner positioning core 2. The turntable 8 can drive the inner positioning core 2 to rotate. By rotating, the laser welder 5 can weld different positions in the welding area in the circumferential direction without moving, thus avoiding the decrease in welding accuracy caused by the active movement of the laser welder 5.

[0028] Furthermore, the turntable 8 is connected to a drive motor 81 for driving its rotation, making it easier for users to control the rotation state of the turntable 8.

[0029] Furthermore, the outer side of the inner positioning core 2 is provided with an outer positioning core 7 for positioning and engaging with the outer hole 11 of the compressor housing 1 in the radial direction. The outer positioning core 7 is connected to a bracket 71, which is connected and fixed to the outer positioning core 7 and the turntable 8 respectively. The outer positioning core 7 can play an auxiliary positioning role for the compressor housing 1 from the outside of the compressor housing 1, further reducing the chance of accidental displacement of the compressor housing 1 during the welding process and improving the welding accuracy.

[0030] Furthermore, a sensor 9 is provided on the outer side of the turntable 8 to sense the rotation angle of the turntable 8. The sensor 9 is electrically connected to the drive motor 81 and the laser welder 5. The sensor 9 can improve the rotation accuracy of the turntable 8. For example, it can be preset that the turntable 8 will stop rotating and stop laser welding after rotating one revolution, avoiding repeated welding of the already welded positions in the welding area and improving the yield rate.

[0031] The working process of this utility model is as follows: The worker first places the compressor housing 1 onto the outside of the inner positioning core 2. The positioning pressure head 4 drives the oil stabilizing ring 3 into the preset position inside the compressor housing 1. Then, the outer positioning core 7 is controlled to be inserted into the outer hole 11 in the horizontal direction. After it is in place, the laser welder 5 starts welding. After the partial welding is completed, the drive motor 81 drives the turntable 8, the inner positioning core 2, the outer positioning core 7, the compressor housing 1 and the oil stabilizing ring 3 to rotate synchronously, so that the laser welder 5 can continue to weld the other connection positions of the compressor housing 1 and the oil stabilizing ring 3 without moving.

[0032] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
