Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for transporting an eccentric part having an eccentric part such as a crankshaft, which is a constituent member of a compressor, in a process of manufacturing or processing.

An object of the present invention is to provide a transport method and a transport device that can automatically process appropriate parts of an eccentric spinal member, etc.

The method and device for conveying the crankshaft of a compressor in a secondary shaft will be explained with reference to FIGS. 1 and 2. The crankshaft 1 is a shaft on which a rotor press-fit portion 2, an oil supply hole 3, an oil supply groove 4, etc. are formed as appropriate. part 5 and the rut core 5 of this ball part 5
P and an eccentric portion 6 having an eccentric axis 6P at a position spaced apart from each other by a certain distance. When this crankshaft 1 is transported, it is normally transported as shown in FIG. That is, the conveying device 7 has a large number of support grooves a, a, a, etc. arranged at equal intervals, and a conveyor 8. A fixed conveyor consisting of A, 8B, 8C, and a support groove b formed in parallel with the support grooves a, a, . . . of each of the conveyors 8A, 88, 8C.
, b..., and is composed of conveyors 9A, 98, 9C arranged alternately with each conveyor 8A, 8B, 8C to support appropriate parts of the eccentric part 6 and bag part 5. It is made up of. As shown by the arrows in Figure 2, this movable cosopair can be cranked by repeating the following movements: - vertically upward movement, - horizontal movement, - vertically downward movement, and - horizontal movement backwards. Fix the shaft 1 in the support grooves a, a... of the conveyors 8A, 8B, 8C.
. . . are sequentially moved to the next one. With such a conveying method and conveying device, only one side of the crankshaft can be processed.

In other words, although it is possible to polish the part indicated by the arrow N shown in Fig. 1, it is not possible to polish the part indicated by the arrow M shown in Fig. 3;
When machining a portion, the crankshaft 1 must be taken out from the above-mentioned conveyance device and machined using a separate machine. Accordingly, the present invention provides a conveying method and a conveying device that eliminate the above-mentioned disadvantages and enable automated processing.One embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In addition, the same parts are indicated by the same numbers as in the above-mentioned subsidiary example. First, to explain the method of transporting the crankshaft, normally the crankshaft 1 is moved parallel to the same machine as explained in the conventional example above, but in the method of the present invention, the eccentric part 6 of the crankshaft 1 is used at this time. This differs from the conventional example because the material is conveyed while being rotated. That is, the support grooves a, a, a...
. . . is moved sequentially at equal intervals. On the other hand, the eccentric part 6 is conveyed while being deviated from the axis 5P of the wisteria part 5 so that the eccentric axis 6P of the eccentric D part 6 rotates. When conveyed in this manner, it is possible to process any part of the crankshaft body 1 by installing processing machines at appropriate positions on the conveyors 8A, 8B, and 8C. Next, the conveying device 7' for providing the above-mentioned conveying means will be explained. Supporting the conveyors 8B and 8C for supporting the shaft part 5 and supporting movable conveyors 9B and 9C for moving the shaft part 5. The grooves are identical to the device 7 described in FIGS. 1 and 2.

On the other hand, a support groove C formed in a conveyor 6A' for supporting the eccentric part 6 and a movable conveyor 9A' for moving the eccentric part 6
is formed as follows. That is, the initial support groove C,,
The center of C2 (eccentric axis ○6P of eccentric part 6) is the conveyor 8B
, 8C is horizontally shifted by a certain distance a from the center of the support groove a (the center of the ball 5P of the ball part 5), and the crankshaft 1 that moves in the support grooves C, , C2 and a is parallel to the center of the support groove a (the ball center 5P of the ball portion 5). Move to. Next, support grooves C3, C4, and C5, which are formed next to support grooves C, C2, are formed at positions that are sequentially eccentric from the center 5P of the ball portion 5. In other words, both shaft cores 5P,
6P distance heron. , a2 gradually become smaller and reach "0" in the groove C5. At this time, the crankshaft 1 has grooves C,...
It will be in a state where it has rotated 900 times from the C2 stage. Next, the support registers C6, C7, and C8 are formed at eccentric positions such that the horizontal distance becomes larger again in sequence from the rod center 5P, and return to a certain distance a from the rod center 5P in the groove C9. At this time, the crankshaft is rotated 180 degrees from the support grooves C, C2. Below, the support grooves can repeat the same form. 10,
11 is a processing machine such as a grinder installed in the support groove opposite to 5 and C9, and grinds when the movable conveyor moves from vertically upward to horizontally as shown by the arrow in Figure 2. I am trying to process it.

By appropriately changing the form of the support groove C in this way,
The crankshaft can be oriented in any direction by using the biased D portion 6, and by installing processing machines 10 and 11, automated conveyance processing becomes possible.

As is clear from the above description, the method of conveying an eccentric shaft member according to the present invention is such that the shaft portion and the eccentric portion of the conveyed member having the shaft portion and the eccentric portion are transferred to a fixed conveyor having a large number of support grooves. In a method in which a movable conveyor having a large number of support grooves sequentially conveys the shaft portions to adjacent support grooves of the fixed conveyor, the shaft portions are conveyed at equal intervals, and the eccentric portion is aligned with the axis of the shaft portion. The conveyor is characterized in that the conveyor is conveyed to adjacent support grooves while being sequentially deviated from the conveyor. The deviation D of the village to be transported
A fixed conveyor combined with a conveyor provided with a number of support grooves for supporting the conveyor, and a number of support grooves arranged in parallel with both of the conveyors, The present invention is comprised of a movable conveyor that sequentially conveys members to support grooves adjacent to a fixed conveyor, and one of the support grooves is opposed to a processing device that processes the conveyed member. According to the method and device described above, it is possible to automatically feed a conveyed member having an eccentric portion such as an eccentric shaft member, and furthermore, it is possible to process the entire shaft outer peripheral surface of the eccentric shaft member etc. during this automatic feeding process. , as before,
There is no need to perform separate machining on each machined surface of the outer circumference of the ball,
It can be transported and processed extremely efficiently.
