The present invention relates to a piston ball pocket measuring device for a compressor, and more particularly, to the provision of a measuring device to mechanically measure the distance of the ball pocket formed in the piston to classify the piston according to the dimension.

Automobile compressor is applied to the automotive air conditioning system is driven by the engine to compress the refrigerant made of low pressure gas in the evaporator to a high temperature, high pressure to transfer the condenser to the condenser.

Although there are various kinds of such compressors, a brief description of the configuration of the swash plate type includes: a shaft that is rotated by the power of the engine, a swash plate provided to be inclined at an angle with respect to the shaft, and a shoe on the outer periphery of the swash plate. The interposed piston is connected to and configured to compress the refrigerant while reciprocating.

In the compressor as described above, the piston, the swash plate, and the shoe operate in a state where they are connected to each other, so that they have the same dimensions and are assembled in one compressor. And the dimensions with the pockets formed in the piston.

Conventionally, in measuring the dimensions of the pockets formed in the piston, the dimensions of the ball pocket of one set of pistons inserted into the compressor were measured using a measuring jig composed of five sets by hand.

When measuring the dimensions of the ball pocket of the piston using the measuring tool as described above, due to the error between the measuring jig phase consisting of five sets of problems, the measurement value of each piston ball pocket occurs unreliable.

That is, when measuring the ball pocket of the piston with each measuring tool, when the same piston is measured with the other measuring tool, a value out of the error range comes out, which makes it difficult to see that the pistons assembled in one compressor have the same dimensions.

As such, by inserting and inserting an irregular piston out of an error range into one compressor, various problems occur such as poor performance or quality of the assembled compressor and poor operation reliability.

Therefore, in the present invention to solve the problems described above, by measuring the dimensions of the ball pocket formed in the piston to be mechanically selected by the same dimensions to provide the ease of sorting by piston dimensions, of course, measurement The main objective is to increase the reliability and to maintain stable quality and performance after assembling in the compressor.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

It is configured to include an indicator 140 for fixing the downward movement of the driven slider 126 to measure the dimensions of the ball pocket.

The piston ball pocket measuring apparatus 100 for a compressor of the present invention as described above,

The piston 101 positioned on the chute 105 by the supply and discharge means 106 is placed in the settling groove 113 of the settling block 112 fixed to the turntable 111.

Then, the turntable 111 is moved by one pitch (by the distance between the settling block and the settling block) by the index motor 110, and the rotation of the turntable 111 is stopped when the position of the measurer 103 is reached.

At the same time, the lifting cylinder 124 of the measurer 103 is operated to lower the measuring plate 123 and lower when the measuring tip 136 fixed to the lower end of the measuring pin 135 is close to the ball pocket of the piston 101. Is stopped.
