Description

Compressor valve unit parts to prevent incorrect assembly

The present invention relates to a valve unit part for a compressor that can prevent misassembly, and in particular, an inlet reed valve and an outlet reed valve are provided from a component preparation stand placed on a compressor assembly line in the process of assembling the valve unit of the compressor. (Outlet reed valve) For compressors that can prevent misassembly to take out valve unit parts such as gaskets and pull out the valve unit parts together to prevent assembly failure A valve unit component.

In general, the compressor constituting the cooling device for a vehicle is selectively received by the power of the engine delivered through the pulley of the vehicle by the intermittent action of the electronic clutch to suck the refrigerant heat exchanged from the evaporator to compress by linear reciprocating motion of the piston It is a device that discharges to a condenser.

There are various types of such compressors, and they are generally divided into reciprocating and rotary type according to the compression method and structure, and in the case of reciprocating type, crank type, swash plate type, wobble plate type type, and rotary type, main rotary type and scroll type type. Is divided again.

In the compressor as described above, the valve unit is installed inside to allow the refrigerant to be sucked and discharged.

Next, a conventional valve unit will be described using, for example, the swash plate compressor shown in FIGS. 3 and 4.

The swash plate compressor of FIGS. 3 and 4 includes a front housing 4; A rear housing 5 coupled thereto; A front cylinder 41 installed inside the front housing 4; A rear cylinder (51) mounted to the rear housing (5); A plurality of double head pistons (6) installed in the reciprocating linear movement in the bores (42) of the front cylinder (41) and the bores (52) of the rear cylinder (51); A drive shaft (7) rotatably installed through the centers of the front and rear housings (4, 5) and the front and rear cylinders (41, 51); A swash plate 8 which is inclined to the drive shaft 7 and rotates in accordance with the rotation of the drive shaft 7 to move the pistons 6 forward and backward; And both valve units 9 and 9 provided between the front and rear cylinders 41 and 51 and the inner surfaces of the front and rear housings 4 and 5. In addition, the valve unit 9 includes a valve plate 91, a suction reed valve 92 and a discharge reed valve 93 installed back and forth with the valve plate 91 interposed therebetween, and a discharge reed valve 93. It comprises a gasket 94 is installed on the side. Therefore, when the drive shaft 7 is rotated by the power of the engine, the pistons 6 are moved forward and backward by the swash plate 8 which rotates in an inclined state together with the drive shaft 7. At the time of the suction stroke of the piston 6 during the forward and backward movement of the piston 6, the suction reed valve 92 is opened while the discharge reed valve 93 is closed so that the refrigerant is sucked into the cylinder bores 42 and 52. In the discharge stroke of the piston 6, the discharge reed valve 93 is opened while the suction reed valve 92 is closed, so that the refrigerant is compressed and discharged.

When assembling the components of the valve unit 9 in the process of assembling the compressor as described above, the components of the valve unit 9 in the compressor assembly line are separately stored in the component preparation stand, and each valve unit 9 is installed by a robot. Although the compressors must be assembled by taking the parts out of the parts stand one by one, in particular, the intake reed valve 92, the discharge reed valve 93 and the gasket 94 are formed in a disk having a thin thickness, so that each valve unit 9 ) As the parts are not drawn out one by one but with several sheets being drawn out and assembled, it causes the assembly failure of the compressor. In the case of the gasket 94 mainly composed of a rubber material, graphite surface treatment is performed to prevent the above-described phenomenon, but the gasket 94 cannot be prevented from being in close contact with each other. In addition, the inside of the compressor is contaminated by graphite, which may not only block the expansion valve or the orifice pipe but also black the site class of the receiver dryer. Furthermore, since the suction reed valve 92 and the discharge reed valve 93 are made of metal, anti-rust oil is applied to the suction reed valve 92 and the discharge reed valve 93 during the distribution process, so the suction reed valve 92 is applied. And the suction reed valves 92 and the discharge reed valves 93 stick to each other by the anti-rust oil film applied to the surface of the discharge lead valve 93 so that the suction reed valves 92 and the discharge reed valves are moved by the robot. It is more difficult to withdraw the 93 one by one.

The present invention has been made in view of the above-described conventional problems, and when drawing out each valve unit part from the parts preparation stage placed on the compressor assembly line in order to assemble the compressor, several valve unit parts are not attached and are drawn out one by one. It is an object of the present invention to provide a valve unit part that can prevent compressor assembly defects.

<Explanation of symbols for the main parts of the drawings>

11: protrusion, 12: groove

In order to achieve the above object, the present invention, in any one valve unit component for the compressor selected from the group comprising a suction rib valve, a discharge reed valve or a gasket constituting a valve unit of the compressor, at least one surface A protrusion is formed, and a groove corresponding to the protrusion is formed on the rear surface.

The projections and grooves may be formed simultaneously by caulking one surface of the valve unit component, for example, by pressing or the like.

When assembling the compressor using the valve unit components of the present invention configured as described above, first, the suction reed valves are separated from the suction reed valves, the discharge reed valves are discharged valves and the gaskets are separated from each other. It is stacked on the component stand installed in the housing. In this way, when each valve unit part is stored in the component preparation stand, for example, the stacking state of the intake reed valve at the front and the intake reed valve located at the rear of the intake reed valve is formed in the groove formed at the rear side of the front intake reed valve. The protrusion formed on the front surface of the insertion hole is formed by the protrusion between the suction reed valves so that neighboring suction reed valves are not in close contact with each other. Therefore, when drawing out each valve unit part from the component preparation stage in the compressor assembly process, each valve part can be pulled out one by one well, and accordingly, the valve unit parts are assembled one by one, thus erroneous assembly of several valve unit parts together. The problem does not occur.

Other features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

As shown in Fig. 1, reference numeral 1 denotes a valve unit component, and only a suction reed valve is illustrated here for convenience, and the misassembly prevention structure, which is a feature of the present invention, applies equally to both the discharge reed valve and the gasket. Detailed description thereof will be omitted.

According to the present invention, one or a plurality of protrusions 11 are formed on one surface of the valve unit component 1 (here, three protrusions 11, 11, 11 are formed and arranged in an inverted triangle). do. In addition, one or more grooves 12 are formed on the rear surface of the valve unit component 1 in correspondence with the projection 11.

The protrusions 11 and the grooves 12 may be formed in various ways. That is, the valve unit part 1 may be formed and then one surface of the valve unit part 1 may be simultaneously formed by separately caulking, for example, by pressing or the like. Groove 12 may be formed.

As described above, when the projection 11 and the groove 12 are formed on the surface of the valve unit component 1, the maximum outer diameter of the projection 11 is due to the thickness of the valve unit component 1 and the maximum inner diameter of the groove 12. It is formed relatively slightly larger. Accordingly, as shown in FIG. 2, the valve unit parts 1 having the protrusions 11 and the grooves 12 formed in this manner are arranged so that the protrusions 11 or the grooves 12 face the same direction. When the layers are stacked in sequence, some gaps are generated between the valve unit parts 1 stacked adjacent to each other by the protrusions 11, so that the valve unit parts 1 are not completely in contact with each other.

Compressor assembly line by stacking valve unit components (1) of the same type configured as described above, that is, suction reed valves with suction reed valves, discharge reed valves with discharge reed valves, and gaskets with gaskets. The valve unit parts (1) stacked on the same type are provided with protrusions (11) and grooves when the valve unit parts (1) are taken out by a robot in the process of assembling the compressor. By (12), since they are not in close contact with each other, they are easily withdrawn one by one. Therefore, since the valve unit parts 1 are assembled one by one in the assembly process of the compressor, there is no problem of incorrect assembly in which the valve unit parts 1 are assembled together.

According to the valve unit part according to the present invention configured as described above, the valve unit parts 1 of the same type are not closely contacted by the projections 11 and the grooves 12 formed in the valve unit parts 1. The same type of valve unit parts (1) are stacked so as to be easily separated. When the valve unit parts (1) are drawn out by a robot during assembly of the compressor and assembled, the valve unit parts (1) do not overlap each other. By pulling out one by one, the assembly failure rate of the compressor can be lowered, thereby improving the assembly productivity of the compressor.
