Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a compressor fixing device that allows a compressor support stand to support a compressor via a cushion member.

(Prior Art) Conventionally, for example, in a refrigerator compressor fixing device, a plurality of support shafts are erected by welding or the like on a compressor support base, and the fitting holes of the cushion members attached to the mounting legs of the compressor are aligned upward. Then, a C-shaped retaining ring is laterally engaged with an engagement groove formed in a portion of the support shaft that protrudes above the cushion member, thereby moving the cushion member upward. It is fixed in a non-removal state.

(Problems to be Solved by the Invention) In the conventional structure using a retaining ring, the parts are attached in two directions from above and from the side, so the assembly work efficiency is poor, and it is difficult to automate the assembly work. In case of
There are problems in that the equipment cost is high and the number of parts is increased because a retaining ring is required.

Therefore, an object of the present invention is to provide a compressor fixing device that can improve the workability of assembly work, reduce equipment costs when automating assembly work, and further reduce the number of parts. .

[Structure of the Invention] (Means for Solving the Problems) The compressor fixing device of the present invention includes a support shaft having a retaining head at the upper end thereof erected on a compressor support base, and a support shaft that is fitted onto the support shaft. A cushion member that supports the compressor and has an elastically expandable fitting hole is fitted from above the support shaft, so that the retaining head protrudes above the cushion member. The feature is that the cushion member is fixed in a non-removal state by this anti-removal head.

(Function) In the compressor fixing device of the present invention, the cushion member is fitted onto the support shaft from above while expanding the fitting hole with the retaining head, and the retaining head is placed above the cushion member. This eliminates the need for a conventional retaining ring and eliminates assembly work from the side.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. First, in FIG. 1, a plurality of, for example, four, support shafts 2 (only two are shown) are mounted on a compressor support stand 1 at its flange 3.
The tube is erected upward by being welded by spot welding or the like. As shown in FIG. 2, the support shaft 2 includes a shaft portion 4, a large-diameter portion 5 formed at the lower end of the shaft portion 4 via an inclined portion 5a, and an upper end portion of the shaft portion 4. It consists of a formed retaining head 6 and the aforementioned flange 3 attached to the lower end of the large diameter portion 5 by welding or the like. Slanted portions 6a are formed whose diameters become smaller in sequence. In this case, in the support shaft 2, if the diameter of the retaining head 6 is dl, the diameter of the large diameter portion 5 is d2, and the scratch of the shaft portion 4 is d3, then d3<di≦d
The relationship is set to 2. Reference numeral 7 designates a cushion member made of an elastic material such as rubber that is fitted onto each of the support shafts 2;
As shown in the figure, a tapered inclined part 8a is formed at the upper end part 8, and a first fitting hole 9 is formed in the center, and a second fitting hole 9 is located below the first fitting hole 9 through an inclined part 10a. A hole 10 is formed, and the fitting holes 9 and 10 can be expanded. In this case, in the cushion member 7, if the diameter of the first fitting hole 9 is d4 and the diameter of the second fitting hole 10 is d, then d,
It is set as #d3<d5#dl. Further, an annular engagement groove 11 is formed in the upper outer circumference of the cushion member 7, into which a circular attachment hole 13a formed in the attachment leg 13 of a compressor 12 of a refrigerator, for example, is fitted. It has become.

Next, the assembly procedure of the above configuration will be explained.

First, the second fitting holes 10 of the four cushion members 7 are inserted into the retaining heads 6 from above the compressor support base 1, and the cushion members 7 are pressed downward to fit into the first fitting holes. 9 is expanded to pass through the retaining head 6, and the retaining head 6 is made to protrude above the cushion member 7. Then, the first fitting hole 9 of the cushion member 7 is restored and reduced in diameter.
As a result, the first and second fitting holes 9 and 10 of the cushion member 7 are fitted into the shaft portion 4 and large diameter portion 5 of the support shaft 2, respectively, and the lower surface portion of the retaining head 6 is inserted into the cushion member. The upper surface of the cushion member 7 is held down, and the cushion member 7 is fixed in a state where it cannot be removed.

Therefore, the mounting hole 13a of the mounting leg 13 of the compressor 12
is applied to the upper end 8 of the cushion member 7 from above and pressed downward, thereby fitting the attachment hole 13a into the engagement groove 11 while elastically reducing the diameter of the second end 8.

According to the above embodiment, the support shaft 2 of the compressor support stand 1
7. Cushion member 7. Since the compressor 12 is fixed to the compressor support stand 1 by attaching the mounting legs 13 of the compressor 12, the assembly work is simplified because there is no lateral assembly unlike the conventional method, and work efficiency is improved. In addition, since parts can be installed in one direction from above, equipment can be simplified and equipment costs can be reduced when automating assembly work, and there is no need for retaining rings as in the past. The number of parts can be reduced.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the cushion member 7 may be attached to the mounting leg 13 of the compressor 12 in advance, and then attached to the support shaft 2 from above. Various modifications are possible without departing from the gist, such as the following.

[Effects of the Invention] As is clear from the above description, the present invention is capable of fitting a cushion member to a support shaft from above while expanding the fitting hole, and moving the retaining head above the cushion member. Since it is made to protrude, the workability of the assembly work can be improved, equipment costs can be reduced when automating the assembly work, and the number of parts can also be reduced.
