Description

Shaft insertion apparatus for blower blades {Shaft insertion apparatus for sirocco type fan}

The present invention relates to a shaft fixing device of the blower blade, and relates to a blade shaft fixing device of the blower for automatically and strongly inserting the shaft in the center of the blower blade.

The blower is one of the air feeders used in an air conditioner, a ventilator or other ventilation device. The blower is divided into axial flow type and centrifugal blower according to the air transfer method. Among them, the centrifugal blower can handle a relatively large amount of air, which is particularly suitable for air conditioning and ventilation. Centrifugal blowers are classified into multi blade type, radial type and air foil type according to the shape and arrangement of blades in the impeller.

1A, 1B, and 1C, the conventional blower blade 10 is provided with a plurality of rotor blades 11 between a circular bottom plate 15 and a ring-shaped frame 12, and the barrier wall 15 In the center of the bearing member 13 is assembled and installed, the bearing member 13 is connected to the ring-shaped frame body 12 so as to be inclined a plurality of supports 14, the shaft hole in the center of the bearing member 13 16 is formed, and the shaft 18 is inserted into this shaft hole 16.

In the assembly operation of the blower blade, the shaft 18 insertion process is very demanding and requires a precise work process. That is, in inserting the heavy-weight shaft 18 into the shaft hole 16 of the bearing member 13, if the horizontal state is not correct, the insertion is not made very difficult workers, and the length of the insertion is considerable, the worker's manual work It takes a lot of work time alone, and it was difficult to secure work safety.

SUMMARY OF THE INVENTION An object of the present invention is to provide a blower blade shaft fixing device for making it simple and quick to insert a shaft into the center of such a blower blade.

The shaft fixing device of the blower blade for achieving the object of the present invention is expected; An axis inserting portion which is installed on one side of the base and comprises a vertical cylinder and a forward and backward transfer cylinder installed at a lower end of the rod of the vertical cylinder; Located on the other side of the base, and the blower blade pedestal so that the axial fixing position of the blower blade is horizontal, and the support unit provided with two vertical columns for preventing the flow of the pedestal side by side; It is achieved by the shaft fixing device of the blower blade which is installed vertically on both sides of the support portion, the idle rolls are formed on each of the upper rods, and the horizontal adjustment portion in which the cylinders are vertically installed on the lower ends thereof.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an overall perspective view for using the shaft fixing device of the blower blade of the present invention, Figure 3 is a side view of the shaft fixing device of the blower blade of the present invention, Figure 6 is the upper, lower height of the shaft fixing device of the present invention An excerpt view of an adjustment.

The shaft fixing device of the blower blade of the present invention according to the drawings comprises a base 110, the shaft insertion portion 120, the support portion 130, and the horizontal adjusting portion 140.

Base 110 is a support plate of a rectangular frame. An approximately middle portion of the base 110 forms an opening 112, and a screw bar 152, a slide bar 151, a driving motor 154, and the like, which are described later, are provided at the bottom of one side thereof.

The shaft insertion part 120 is installed on one side of the base 110, and is installed in a predetermined housing structure such that the vertical cylinder 121 is movable in the vertical direction, and the rod 122 of the vertical cylinder 121 is disposed. At the end, the cylinder 123 is moved forward and backward in the horizontal direction, but the push rod 125 is installed at the tip of the cylinder rod 124.

Support portion 130 is located on the other side of the base 110, a vertical column 132 for preventing the flow of the pedestal 131 and the pedestal 131 so that the shaft fixed position of the blower blade 10 is horizontal. ) Can be installed side by side.

Particularly, the pedestal 130 is provided with a fork insertion hole 133 across the front and rear surfaces thereof so that the fork of the forklift can be inserted so that the pedestal 130 itself can be moved as a forklift while the blade 10 is raised. Let's do it.

Two horizontal adjustment unit 140 is installed side by side on both sides of the support portion 130, on each of the top rod 141 is formed with a support plate 144 containing the idle roll 142, the bottom Each cylinder 143 is provided.

In particular, one horizontal adjustment unit 140 of the horizontal adjustment unit 140 is provided on the moving plate 153 which will be described later so as to be movable in the opening 112.

That is, the screw bar 152 horizontally / installed on the opening 112 and the slide bar 151 installed on both sides side by side thereof, and the screw bar 152 as the driving motor 154 installed on one side of the bottom of the base 110. ), And the moving plate 153 is screwed onto the screw bar 152 as the ball nut 155, and the slide bar 151 is slidably wrapped around the slide bar 151. It should be installed.

One of the above-described horizontal adjustment unit 140 is installed on the moving plate 153 to adjust the height when the shaft 18 is inserted, as well as to maintain an appropriate interval.

4 is a longitudinal cross-sectional view only for explaining the operation of the shaft fixing device of the present invention, Figure 5 is a cross-sectional view of the shaft fixing device of the present invention.

The operation of the blower blade shaft fixing device of the present invention will be described based on these figures.

First, the pedestal 131 mounted with the blade 10 on the fork of the forklift truck is moved to a predetermined position on the base 110, and then the shaft 18 is placed on one side horizontal adjusting unit 140.

Then, by adjusting the cylinders 143 of the horizontal adjustment unit 140 on both sides to adjust the height of the shaft hole 16 of the blade (10).

At this time, the position of the movable plate 153 is moved forward and backward so that the left and right lengths of the shaft are balanced before the shaft 18 is raised.

Thereafter, the shaft 18 is pushed to a predetermined pressure by the push rod 125 of the cylinder 123 whose upper and lower heights are adjusted as the cylinder 121. Of course, the moving plate 153 moves at a similar speed to adjust while maintaining the left and right balance so that the shaft 18 does not fall until the shaft 18 is inserted into the shaft hole 16.

When the shaft 18 is inserted to some extent along the central shaft hole 16 of the blade 10 by the crimping operation of the shaft 18, the shaft 18 is attached to the rollers 142 on one side horizontal adjusting unit 140. It is supported and progressed, and the crimping operation of the shaft 18 is completed.

After the forklift is inserted into the fork insertion hole 133 of the pedestal 131 again, the forklift lifts the pedestal 131 to move the blade to the blower assembly plant.

Thus, the blower blade shaft fixing device of the present invention improves the difficulty and manual inaccuracy caused when inserting / fixing the shaft into the shaft hole of the conventional large blower blade, and the assembly work is performed quickly, and the shaft insertion / process is an automated facility. This has the effect of being made quickly.
