Description

Prevention device for pipe lins of compressor, leak testing method and plating method for compressor using the same}

The present invention relates to a compressor piping stopper and a leak test and plating method of a compressor using the same, and more particularly, a compressor piping stopper device and a compressor leak using the same, which can be used for both a leak test and a plating process of a compressor. It relates to a test and plating method.

2. Description of the Related Art Generally, a compressor is used in a refrigeration cycle such as a refrigerator or an air conditioner to compress a refrigerant. The compressor is made of a metal enclosed container.

The sealed vessel is connected with a suction pipe for guiding the uncompressed external refrigerant into the sealed vessel and a discharge pipe for guiding the refrigerant compressed in the sealed vessel to the outside of the sealed vessel. A compression unit that performs an action, and a drive unit for providing a compression driving force of the refrigerant is provided.

The sealed container is divided into upper and lower containers, and the upper container and the lower container are welded to each other so that the inner space is sealed while the compression unit and the driving unit are installed therein.

On the other hand, to ensure product reliability, the compressor after welding the sealed container is subjected to a leak test that checks the airtightness of the sealed container, and only the products that pass the leak test correctly are shipped with the surface coated. It is becoming.

In order to perform the leak test, a plurality of pipes connected to an airtight container are first blocked by a leak test stopper provided with a high bonding strength and a metal material to withstand high pressure. The leak test stopper is divided into an injection stopper for blocking a pipe in a state where gas can be injected, and a general stopper provided to simply block the pipe. In this state, a high pressure gas is injected into the hermetic container through an injection cap, and the compressor after the gas injection is completed is introduced into the water tank. In a closed container with a leak, bubbles are generated at the corresponding site, and thus it is easy to determine whether there is a defect.

 After passing through the leak test, the compressor is transferred to a plating process, and the surface is plated. At this time, the compressor is formed with a plating layer on the surface by an electroplating method in which the compressor is put in an electrolyte solution.

In addition, the leak test plugs of the metal material installed in the pipe of the airtight container before the plating work are all separated from the pipes, and the pipe of the leak test plug separated from the leak test pipe is simply made of rubber material. Will be fitted. This is because, in the case of the leak test stopper used in the leak test, the surface is in electrical contact with the pipe. Therefore, when the leak test stopper is used during the plating process, the current applied to the compressor during the electroplating process is applied to the pipe. The plating is also made to stopper while being transferred to the stopper surface, to prevent this.

However, in the case of the leak test and the plating operation as in the prior art, when the pipe of the compressor is blocked with a separate stopper, the leak test stopper is separated from the compressor pipe between the leak test process and the plating process, and the leak test stopper is separated again. Since a separate plug separation and joining process for blocking the finished pipe with a plug for plating is added, there is a problem in that process water and manpower are wasted due to the production of the compressor.

In order to solve such a problem, it may be considered that a leak test stopper is used without a separate plating stopper and the leak test stopper is not separated from the pipe from the leak test process to the plating process. Since the stopper is plated as a whole and it is difficult to use any more, another problem arises in that the expensive leak test stopper can only be used for one-time use.

For reference, the blocking member 70 and the fixing holder 82 are provided with gas passing holes 72 and 82a to allow gas to be injected into the sealed container 3 in the leak test process.

In addition, the closure device 1A is provided with a locking device 90 so that the closure device 1A coupled to the pipe 4 can be prevented from being separated by the high pressure gas pressure inside the sealed container 3 during the leak test process. In addition, the locking device 90 is provided to seal the pipe 4 in a one-touch manner to improve the sealing workability of the pipe 4 by the plug device 1A.

To this end, the guide body 40 is slidably provided in a state where one end is entered into the housing 10, and the guide body 40 is disposed around the guide body 40 between the head 50 and the housing 10. The second elastic member 100 is provided to elastically support the outer side of the housing 10 is installed, the locking device 90 is installed at the end of the guide body 40 inside the housing 10, the second elastic member ( In a state in which 100 is pressed, the pipe 4 coupled to the coupling hole 42 is allowed to be released, and in the state in which the second elastic member 100 is restored, the pipe coupled to the coupling hole 42 ( It is provided to block the omission of 4).

A locking protrusion 44 is provided on an outer circumference of the guide body 40 that enters the inside of the housing 10 so that the guide body 40 is not separated from the housing 10, and a locking protrusion is provided on the inner circumference of the corresponding housing 10. The catching jaw 14 is provided to catch the group 44, and the head 50 is provided with a support part 53 in the form of a flange for supporting the second elastic member 100. Therefore, when the head 50 is pressed toward the housing 10 while the housing 10 is held, the guide body 40 slides into the housing 10 while the second elastic member 100 is compressed. When the external force is removed again, the guide body 40 is returned to its original state so that the catching protrusion 44 is caught by the catching jaw 14 through the restoring force of the second elastic member 100.

In addition, the locking device 90 is provided with a pipe passage hole 91a for the passage of the pipe 4 at the center thereof, and a snap jig 91 installed at the end of the guide body 40 toward the coupling hole 42 and a snap. The third elastic member 92 for elastically supporting the jig 91 in an inclined state and a stopper 93 fixed to the inner circumference of the housing 10 inside the first sealing member 30 are included.

In the case of the pipe passing hole 91a provided in the snap jig 91, the pipe passing hole 91a is larger than the diameter of the pipe 4 to allow the pipe 4 to be pulled out when the snap jig 91 maintains a horizontal state. The pipe passage hole 91a supports both sides of the circumference of the pipe 4 in a staggered state when the snap jig 91 maintains the inclined state, thereby blocking the pulling out operation of the pipe 4. The snap jig 91 around the pipe passage hole 91a is provided with an inclined surface 91c to guide the pipe 4 toward the pipe passage hole 91a.

At this time, the end of the pipe 4 is in a state seated in the seating groove 71 of the blocking member (70). As soon as the coupling operation of the pipe 4 is completed, the snap jig 91 rotates to its original state automatically through the restoring force of the third elastic member 92 as shown in FIG. 7 to maintain the inclined state. Accordingly, the coupling hole 42 inside the pipe 4 is supported in a state in which both sides of the circumference is staggered through the pipe passing hole 91a, and thus the pulling-out operation is blocked.

Therefore, the closure device 1A in this state can maintain the state of being strongly coupled to the end of the pipe 4 in a state in which the inside of the airtight container 3 is sealed in the leak test and the plating process of the compressor 2.

In addition, when both the leak test and the plating process are completed, the guide body only presses the head 50 toward the housing 10 while holding the housing 10 to press the third elastic member 100 as shown in FIG. 8. Since the snap jig 91 is pushed back to the stopper 93 by the sliding operation of the 40 to be in a horizontal state, the locking operation of the locking device 90 with respect to the pipe 4 is released, thereby closing the stopper device ( 1A) can be easily separated from the pipe 4.

As described above, the housing opposite to the insertion hole 21 may be secured to ensure watertightness between the housing 10 and the guide body 40 even when the locking structure of the pipe 4 using the sliding motion of the guide body 40 is adopted. 10) Between the inner circumference and the outer circumference of the guide body 40 corresponding thereto, a second sealing member 110 provided with fluorine rubber is installed to seal the housing 10 and the guide body 40 in a slidable state.

The second sealing member 110 may be provided in plural numbers spaced apart from each other along the sliding direction of the guide body 40 so that the guide body 40 may not be tilted to one side in the sliding process. A fixing groove 46 is provided on the inner circumference of the guide body 40 to fix the sealing member 40.

In the case of the structure of the general plug device 1B shown in FIG. 5, except that the shape of the head 50 ′ is changed while the gas injection nozzle is omitted, the remaining structure and operation are the same as those of the gas injection plug device 1A described above. Since the same, detailed description thereof will be omitted.

Next, a leak test process and a plating process of the compressor 2 using the compressor piping stopper 1 configured as described above will be described.

First, in order to perform the leak test process, the compressor tubing stopper device 1 is pressurized and fixed to the respective piping 4 of the compressor 2 in which the welding of the sealed container 3 is completed, thereby closing the sealed container ( 3) The inside is completely sealed, and in this state, the test gas is filled into the sealed container 3. At this time, the test gas is injected into the sealed container 3 through the gas injection nozzle 51 of the gas injection plug device 1A of the compressor piping plug device 1.

Compressor (2) is completely filled with the test gas in the sealed container (3) is put into the water tank to check whether the bubble is generated, in the case of the compressor (2) is not generated bubble is immediately transferred to the plating process. .

The compressor 2 transferred to the plating process is subjected to an electroplating process in a state of being injected into the electrolyte solution after being immediately washed without replacing the compressor piping plug 1. In this case, since the compressor 2 and the metal to form the plating layer are used as the cathode and the anode, respectively, in the state in which the electrolyte is added to the electrolyte solution, the electrolyte solution contains the metal ions forming the plating layer. The plating layer is formed on the surface of the compressor 2 through the reduction of ions.

In this plating process, the electrolyte solution is prevented from infiltrating into the compressor pipe stopper 1 through the insertion hole 21 and the pipe 4 through the sealing action of the first sealing member 30, and further, the first sealing member 30. Since the sealing member 30 maintains an insulated state between the stopper device 1 for the compressor pipe and the pipe 4 through the insulating action, the plugging device 1 for the compressor pipe is plated together with the compressor. You will not.

When the plating process is completed, the compressor piping stopper 1 is detached from the pipe 4 in a one-touch manner, and even when the plating process of the compressor piping stopper 1 is completed, there is no risk of damage. This becomes possible.

In the leak test and plating process using the compressor pipe stopper 1 of the present invention as described above, a process of replacing the stopper device 1 for sealing the pipe 2 of the compressor 2 between the leak test process and the plating process is performed. Since it is eliminated, it is possible to effectively reduce the number of processes and manpower associated with the production of the compressor.
