Description

Loading device for vacuum pump rotor processing equipment {AN AUTO-LOADING OF VACUUM PUMP ROTOR MANUFACTURING SYSTEM}

The present invention relates to a loading apparatus of a vacuum pump rotor processing apparatus, and more particularly, in the machining of a rotor of a vane type vacuum pump, the supply of the processing rotor supplied to the grinding apparatus is sequentially processed according to the machining process. It is intended to improve workability, productivity and processing precision by loading on the

In general, the vacuum pump sucks and discharges air to generate a negative pressure, and the type of the vacuum pump is generally a reciprocating type such as a piston or a plunger and a rotary type such as a vane.

Here, the vane-like rotary type is a rotor having a plurality of vanes elastically protruding in a circular pump chamber is eccentrically axially accumulate, while the rotor is rotated by a driving source such as a motor, the vane is inhaled to suck in air Discharge to generate negative pressure.

The rotor of the vane pump as described above is mainly manufactured by sintering an alloy having excellent abrasion resistance to impart wear resistance, and the rotor sintered as described above has an involute type spline shaft hole in the center portion for coupling the drive shaft. Because it is perforated and cannot be installed on an automatic lathe, it is fitted into a spline shaft hole and is fixed by arranging a separate jig, and then the rotor is installed on a one-handed workbench by manual labor and then ground by grinding grinding.

However, in the conventional processing method as described above, separate jigs must be coupled to the sinter-molded rotor, and they must be installed on the workbench by manual operation. There is a problem, such as, there was a high risk of a safety accident due to the worker exposed to the machine in the loading and unloading process of the rotor.

Accordingly, the present invention has been made in order to solve the above problems, a loading device for loading the processing rotor to the machining position, a grinding device for clamping and grinding the processing rotor loaded by the loading device, and in the grinding device In the configuration of the discharge device for receiving the rotor ground by the upright discharge, the supply of the processing rotor through the loading device is to be supplied and loaded one by one in sequence according to the processing process.

Hereinafter, described in detail by the accompanying drawings as follows.

The present invention is to be able to complete the machining operation of the vane vacuum pump rotor quickly and precisely, the loading device 100 for loading the processing rotor (1) to be supplied in a single grinding position, and the loading device ( Grinding device 200 for grinding by the turret tool 230 by inserting the spline shaft ball of the processing rotor (1) loaded by the 100, and the rotor (1) grinding is completed by the grinding device 200 is discharged ) Is configured to discharge device 300 to discharge the inclined and upright discharge by increasing the speed.

Here, the loading device 100 is a supply chute 110 is provided with a rotor sensor 111 at the end for detecting whether the processing rotor (1) is continuously supplied and the storage of the rotor (1), and the supply chute The operation of the chute actuator 121 and the chute actuator 121 which opens and closes the end of the supply chute 110 so that the discharge of the processing rotor 1 supplied to the 110 is performed in a single order is supplied and prepared. A discharge actuator 120 including a supply actuator 122 for supplying the rotor 1, a V block 130 on which the processing rotor 1 discharged by the discharge actuator 120 is seated, and the discharge actuator ( The rotor sensing plate 131 for slowing down the speed of the rotor 1 discharged from the 120 and detecting the state of being seated on the V-block 130, and the processing rotor 1 seated on the V-block 130. The finger 143 protruding by the finger actuator 141 Is gripped by the take-off and by elevating the take-working rotor (1) to lift the actuator 142 is made of a loading Pinker 140 for loading into the processing position.

On the other hand, the grinding device 200 is a chuck 210 for inserting the spline shaft ball of the processing rotor (1) loaded by the loading finger 140 of the loading device 100, and on the opposite side of the chuck 210 The turret tool 220 which is coupled and axially rotated on the side of the processing rotor 1 fixed by the tailstock 220 and the chuck 210 and the tailstock 220, and grinds the outer surface of the processing rotor 1. (230).

In addition, the discharging device 300 has a withdrawal basket 310 to be haunted to the processing position, a transfer guide 320 for slowing and conveying the rotor 1 introduced into the withdrawal basket 310, and the transfer guide 320 The inclined guide 330 for erecting and discharging the rotor (1) to be transported along.

Hereinafter, the operation of the present invention will be described.

As described above, in the rotor processing apparatus including the loading device 100, the grinding device 200, and the discharge device 300, the loading device 100 is supplied with the supply chute 110, the discharge actuator 120, and the V block ( 130 and the loading finger 140, the present invention first receives the processing rotor 1 in the supply chute 110 of the loading device 100. At this time, the rotor sensor 111 provided at the end of the supply chute 110 detects this.

When the present invention is operated in the state in which the rotor 1 is supplied to the supply chute 110 as described above, the chute actuator 121 of the discharge actuator 120 protrudes so that the rotor 1 of the supply chute 110 flows. At the same time as the feed actuator 122 is immersed so that one roll rotor (1) is supplied to the V-block 130 is not lowered.

At this time, the speed of the rotor 1 supplied with the rotor sensing plate 131 provided at the front end of the V-block 13 is reduced, and the mounting of the V-block 130 of the rotor 1 is sensed.

As described above, when the rotor 1 is detected on the V-block 130 by the rotor sensing plate 131, the finger 143 protrudes by the finger actuator 141 and is seated on the V-block 130. After inserting the rotor 1, the finger actuator 141 is retracted by immersion, and then the lifting finger 142 descends by the lowering of the lifting actuator 142 to load the rotor 1 in the working position.

When the chuck 210 and tailstock 220 of the grinding device 200 are loaded on the loaded rotor 1 through the loading process as described above, the loading finger 140 is returned to its original position.

As described above, the rotating rotor 1 is rotated in the state in which the rotor 1 is axially held and the turret tool 230 is rotated in proximity to perform the grinding operation.

When the grinding processing of the processing rotor 1 through the grinding operation as described above is completed and the tailstock 220 is retracted, the withdrawal basket 310 of the discharge device 300 is advanced to be positioned to the lower portion of the rotor 1. .

At this time, when the chuck 210 discharges the finished rotor 1, the discharged rotor 1 is transferred to the transfer guide 320 through the withdrawal basket 310, and discharged while standing by the inclined guide 330. So all the work is done.

Therefore, the present invention is very useful to improve the workability and productivity and processing accuracy by continuously feeding the rotor one by one in the grinding process of the rotor, and performing the grinding process by loading the loading of the rotor in the correct position.
