On the other hand, in explaining the embodiment of the present invention, refer to the process sequence ①②③④⑤ indicated in the drawings and will be described by the order.

① Process

The process of positioning the vehicle's compressor drive transmission unit, which is an object of engagement of the snap ring, in the unit mounting portion 104 is performed.

Here, the present invention, in performing the above step (1), a fixing table (104-) operated by the lifting and lowering cylinder (104-1) of the unit mounting portion 104 so that the subsequent snap ring coupling process can be made more precisely 2), the fixed table (104-2) is installed on the center line of the rotating means (104-3) for rotating the upper turntable (104-4), and the turntable (104-4) to the spring at a predetermined distance to the upper surface It is composed of the first and second position adjusting pins 104-5 and 104-6, which are protruded upward by a predetermined length, respectively. In addition, the first and second position adjustment pins have a sensor (not shown) for sensing the protruding state and position.

The unit mounting unit 104 according to the above configuration is a dedicated device of the vehicle compressor drive transmission unit 1 described in the background art, the top of the eccentric rotation shaft 15 of the vehicle compressor drive transmission unit 1 and the eccentric rotation bracket 14 ) The snap ring insertion space groove (16) formed between the upper ends can be automatically positioned in a constant direction at all times.

* For reference, the snap ring insertion space groove 16 is a configuration of a conventional vehicle compressor drive transmission unit 1, in the process to be described below, in order to automatically enter the snap ring insertion space groove 16 automatically in the above configuration It is efficient that the unit mounting portion of the precise positioning of the snap ring insertion space groove 16 in a specific direction.

In other words, in step (1), when the vehicle compressor drive transmission unit 1 is mounted on the unit mounting portion 104, the cover 11 of the vehicle compressor drive transmission unit is fixed on the fixed table 104-2, At the same time, a camwheel 12' protruding downward in a semicircle at the bottom of the rotating cam 12 is located on the turntable 104-4.

Then, while the turntable 104-4 is rotated by the rotating means 104-3, the upper and lower snap rings are inserted by rotating the camwheel 12' with the first and second positioning pins 104-5 and 104-6. The space groove 16 is positioned in a specific direction.

To explain the action in more detail by way of example as follows.

* For reference, the cam wheel and the rotating cam of the compressor driving device for the vehicle, and the eccentric rotating shaft and the eccentric rotating bracket are rotated simultaneously in the cover in an integral configuration. In addition, the position of the snap ring insertion space between the shape position of the camwheel and the eccentric rotation shaft and the eccentric rotation bracket is arranged in a position as shown in FIG. 14(c) when viewed from a plane. And the position of the snap ring insertion space groove required by the present invention is based on the'fixed position' shown in Fig. 14(c). In addition, the first and second position adjustment pins of the turntable are in a protruding state and a pressing state, and their positions are always positioned constant by a detection sensor.

As described above, when the camwheel 12' is mounted on the turntable 104-4 as shown in Fig. 14(a), the first position adjustment pin 104-5 of the turntable is pressed by the camwheel 12'. The second position adjusting pin 104-6 maintains a protruding state.

Then, detection of this state is made, and at the same time, the turntable 104-4 rotates counterclockwise so that the pressing state of the first position adjustment pin 104-5 from the camwheel 12' is released, and then the first When the pressed state of the position adjusting pin 104-5 is released (return to the protruding state), the straight protruding surface of the cam wheel 12 is turned to the first position adjusting pin 104-5 while rotating clockwise again. Push it to rotate to the right position.

When the cam wheel 12' is in the initial position as opposed to the above-exemplified position, the second position adjustment pin is implemented in the opposite action to position the cam wheel, and the cam wheel is mounted on the turntable by avoiding the first and second position adjustment pins. If possible, the status of the first and second positioning pins (protrusion hold) is sensed and the turntable continuously rotates the first and second positioning pins clockwise and vice versa, thereby positioning the camwheel in the correct position.

② Process

When the vehicle driving drive unit and the snap ring inserting space groove 16 of the drive transmission unit to the unit mounting portion 104 by the above process are completed in the required position required by the present invention, the snap ring of the coupling portion 103 The coupling tool 25 performs a process of drawing out the snap ring a from the supply unit 101.

In detail, in step ②, if the supply portion 101 is supplied with a snap ring (a) in line with one end of the supply rod 101-1 that is in line with the snap ring coupling tool 25,

The lifting/lowering cylinder 21 of the coupling portion 103 lowers the snap ring coupling tool 25 to one end of the supply rod 101-1 to the lower circumferential surface of the tool body 26 of the snap ring coupling tool 25. One snap ring (a) is adsorbed and fixed by magnetic force with a plurality of configured magnetics (28).

At this time, at the same time as the above process, the lower circumference of the tool body 26 supports the rear part of the snap ring (a) on which the snap ring rear hook 29 on one side is adsorbed, prevents lateral flow, and further reduces the central shaft of the tool body 26 ( 2-2) The inner periphery of the snap ring protruding at the bottom 2-5 is firmly prevented from the lateral flow and rotational flow of the snap ring (a) while being inserted/positioned inside the snap ring (a).

Next, when the above operation is completed, the preceding lifting and descending cylinder 21 returns the snap ring coupling tool 25 to the initial position to complete the process ②.

* For reference, the supply part carried out in the above process uses a normal alignment vibration feeder, and the supply rod of the alignment vibration feeder is fixed at the snap ring position so that the opening of the sensor and the snap ring can be supplied in one direction at all times. Poetry).

③ Process

When one snap ring (a) is pulled out by the snap ring coupling tool 25 by the above step ②, the transfer unit 102 mounts the snap ring coupling tool 25 of the coupling unit 103 to the unit mounting portion 104 The process of positioning/moving in the vertical line of the snap ring insertion space groove 16 of the vehicle compressor drive transmission unit 1 is performed.

④ Process

When the snap ring coupling tool 25 is moved to the upper position by the above process ③, the lower end of the tool body 26 of the snap ring coupling tool 25 is previously inserted into the snap ring insertion space groove 16 of the compressor driving transmission unit for the vehicle described in the process ①. ) To descend and perform a process with a waiting state for engagement of the snap ring.

In detail, in the ④ process, the up and down cylinder 21 of the coupling portion 103 descends the snap ring coupling tool 25 by a certain distance, and adsorbs it to the lower and lower circumferential surfaces of the tool body 26 of the snap ring coupling tool 25. One snap ring (a) is positioned in the snap ring insertion space groove (16) between the top of the eccentric rotation shaft (15) and the top of the eccentric rotation bracket (14) of the vehicle compressor drive transmission unit.

At this time, since the snap ring insertion space groove 16 does not usually have a size such that the entire size of the snap ring can be inserted, in the present invention, the lower part of the tool body 26 is partially overlapped when viewed from the top with the eccentric rotation shaft 15 at the top. It is lowered as shown in FIG. 8.

Then, the avoiding portion 27 formed on the lower portion of the tool body 26 avoids the contact from the eccentric rotation shaft 15 so that the snap ring a of the lower circumferential surface of the tool body 26 is positioned as shown in FIG. 9.

In addition, when the tool body 26 is lowered, the central shaft 2-2 configured on the inner side thereof rises upward while its lower surface contacts the upper surface of the eccentric rotation shaft 15, and the inner side of the snap ring (a) as shown in FIG. It has a state of avoidance with the eccentric rotation shaft 15 while releasing the peripheral fixed state.

* For reference, the central shaft is pushed up and down by the upper spring and operated in its original position.

⑤Process

When the snap ring (a) is completed in the snap ring insertion space groove (16) of the vehicle compressor drive transmission unit by the above step ④, the snap ring (a) is engaged with the eccentric rotation shaft (15) of the vehicle compressor drive transmission unit. .

In detail, in step ⑤, when the step ④ is completed, the front and rear flow cylinders 23 of the coupling portion 103 move the snap ring coupling tool 25 to the front position as shown in FIG. 3, so that the snap ring coupling tool 25 The snap ring (a) located on the lower circumferential surface of the tool body 26 is forced into the upper end of the eccentric rotation shaft 15 of the compressor driving transmission unit for the vehicle. ) The rear side of the snap ring supporting the rear side 29 pushes the rear side of the snap ring (a) toward the eccentric rotation shaft 15 as shown in FIGS. 9 and 10, so that interference fit is achieved.

Finally, the continuous process is performed in the reverse order and repetition of the above process.

Through the above-described configuration and a series of processes comprising the configuration, the present invention provides a feature capable of more efficiently performing a snap ring coupling operation with an eccentric rotating shaft of a vehicle compressor driving device.

In addition, the present invention further ensures the reliability of the work by adding the step ⑥ to inspect the coupling state of the snap ring (a) after the step ⑤ with the inspection section 105.

The inspection unit 105 is installed on one side of the moving plate 2 of the coupling unit 103, the lifting and lowering cylinders 105-2 for raising and lowering the mounting table 105-1, and the mounting table 105-1 A sensing sensor (105-3) installed on the side, and a pressurized rim (105-4) that protrudes downward at a certain length around the lower surface while being fired with a spring at the bottom of the regular mounting table (105-2), and a certain depth is formed at the center of the lower surface It consists of a pressing rod (105-6) having an insertion groove (105-5).

Therefore, in step ⑥ by the inspection unit 105 added after the completion of the ⑤ process, when the engagement of the snap ring (a) is completed and the coupling unit 103 returns to its original position, the inspection unit 105 snaps the ring (a). It is positioned in the same line as the eccentric rotation shaft (15) of the combined vehicle drive driving unit.

Then, the lifting/lowering cylinder 105-2 lowers the pressing rod 105-6 at the bottom of the mounting table 105-1, so that the pressing rim 105-4 at the bottom of the pressing rod 105-6 snaps (a). Make contact with the top surface.

In addition, when the pressing rim of the pressing rod (105-6) in contact with the snap ring in the above process, the pressing rod, which was lowered by the lifting/lowering cylinder, reacts upward due to contact with the snap ring, and its upper end contacts the upper sensing sensor. The current state, that is, the eccentric rotation axis, is used to determine whether the snap ring is engaged.

At this time, the pressing rod induces the insertion of the upper end of the eccentric rotating shaft into the insertion groove in the center of the lower surface to avoid mutual contact during the above action, and at the same time, the outer circumferential pressing rim makes contact with the snap ring located on the outer peripheral edge of the eccentric rotating shaft.
