Description

Motor clamp for mounting belt to motor unit

The invention relates to a device for assembling a washing machine motor assembly, in particular to a device for assembling a belt to a washing machine motor assembly.

A motor for driving a belt wound on a pulley coupled to a shaft of the motor should be properly spaced from a driven member receiving a driving force from the motor through the belt. At this time, in order for the motor to be installed to drive the driven member stably, the tension of the belt should be considered. Figure 1 shows the motor assembly of a washing machine. In the figure, both the motor 1 and the clutch 3 driven by the motor through a belt are fixed to the bracket 4 . The bracket 4 is fixed on the bottom surface of the drum (not shown). In the motor assembly of the washing machine, before the belt 2 is assembled to the motor 1, the motor 1 is temporarily mounted on the frame by simply inserting the bolt 8 through the slot hole 6 of the flange fixing part 5 into the bolt hole 7 of the frame 4. 4. In this state, the belt 2 is assembled to the motor 1, and the motor 1 equipped with the belt 2 is placed on the platform to be transferred to the bolt automatic coupling device. Thereafter, the motor 1 is fixedly coupled to the bracket 4 by fastening bolts 8 . At this time, considering the tension of the belt 2 , a certain distance should be properly maintained between the motor 1 and the bracket 4 .

However, as shown in FIG. 1 , before the bolts 8 have been fully tightened, the motor 1 is tilted due to the tension of the belt 2 . Therefore, when the bolt 8 has been fully tightened, the position of the motor 1 is changed, so that the tension of the belt 2 is also changed.

The present invention aims to overcome the above-mentioned problems in the prior art, and it is therefore an object of the present invention to provide a motor clamping device whereby the position of the motor is maintained precisely and stably.

To achieve the above purpose, the present invention provides a motor clamping device. This device includes a traction part for resisting the tension of the belt and a pushing part for pushing the motor against the traction force of the traction part to prevent the motor from rotating due to a pair of forces generated by the traction force of the traction part and the tension of the belt .

According to the invention, the device has a supporting portion for supporting both the pulling and pushing portions. The mounting position of the motor can be adjusted by holding the motor by the pulling and pushing two parts, and by moving the supporting part in the forward and backward directions.

According to the present invention, the motor temporarily fixed to the bracket can be erected in an upright position, so that the mounting position of the motor can be kept constant and the tension of the belt can be precisely adjusted.

The above-mentioned purpose and other advantages of the present invention will become more apparent by describing a preferred embodiment thereof in detail with reference to the accompanying drawings, wherein:

Fig. 2 is the perspective view showing the clamping device of the belt drive motor of the present invention;

Fig. 3 is a partial cross-sectional view showing the action of the jaws of the holding device shown in Fig. 2 before the holding device loads the motor;

Figure 4 is a partial sectional view illustrating the action of the jaws of the clamping device shown in Figure 2 after the clamping device has loaded the motor;

FIG. 5 is a partial sectional view showing a motor held by the holding device shown in FIG. 2 .

Hereinafter, a preferred embodiment of the present invention will be described. In the various figures, the same parts have the same reference numerals.

Fig. 2 shows a clamping device of a belt drive motor according to a preferred embodiment of the present invention. In the drawing, the holding device includes an assembly plate 10 ; a guide rail 11 formed on the assembly plate 10 ; and a moving plate 12 slidably supported on the guide rail 11 . The moving plate 12 is moved in forward and backward directions by operating cylinders 13 mounted on the mounting plate 10 . The stopper 14 is fixed on the assembly plate 10 and prevents the movable plate 12 from detaching from the assembly plate 10 .

Claws 15 and 16 are pivotably mounted on the movable plate 12 and the connecting plate 17 . The connecting plate 17 connects the jaws 15 and 16 to the jaw cylinder 18 and is moved in the forward and backward directions by the jaw cylinder 18 . Claw cylinders 18 are mounted on the bottom surface of the moving plate 12 and move the connection plate 17 in forward and backward directions, thereby moving the claws 15 and 16 . When the motor 1 is clamped by the claws 15 and 16 , the upper part of the motor 1 is pushed by the pusher 19 . The pusher 19 is connected to a push cylinder 20 fixed on the mounting plate 10, and is moved forward and backward by the push cylinder 20.

Next, the operation of the motor holding device according to the preferred embodiment of the present invention will be described.

Referring to FIG. 3 , the jaw cylinder 18 pushes the connecting plate 17 toward the motor 1 when the motor 1 is fed into the clamping device by a conveyor belt (not shown). At this point, the jaws 15 and 16 are pivoted against each other so that the motor 1 can be housed between their ends 15a and 16a.

In this state, as shown in FIG. 4 , when the moving plate 12 is moved forward by the operating cylinder 13 , the motor 1 is placed in the space formed between the claws 15 and 16 . In this state, the jaw cylinder 18 returns to its initial position, while at the same time, the push cylinder 20 starts to operate. When the jaw cylinder 18 has returned to its original position, the ends 15a and 16a of the jaws 15 and 16 pivot towards their initial position as shown in dotted lines in FIG. 2 , thereby gripping the motor 1 . At this time, as shown in FIG. 5 , the claws 15 and 16 contact one side 1 a of the motor 1 to pull one side 1 a of the motor 1 with a predetermined traction force, and the pusher 19 pushes the other side of the motor 1 through the push cylinder 20 . side 1b.

At this time, in order to prevent the inclination of the motor 1 caused by a pair of forces generated by the traction force of the claws 15 and 16 and the tension of the belt 2, the pushing point of the pusher 19 on the motor 1 should be lower than the claws 15 and 16. The contact points of the ends 15a and 16a of the motor 1. Preferably, the distance between the ends 15a and 16a of the jaws 15 and 16 and the pusher 19 is equal to the width between the sides 1a and 1b of the motor 1 . In this case, the motor 1 is firmly held while the bolts for assembling the motor 1 are being tightened.

That is, both sides 1a and 1b of the motor 1 inclined as shown in FIG. At this time, the position of the motor 1 can be adjusted by controlling the operation cylinder 13, so that the tension of the belt 2 can also be adjusted.

After tightening the bolts, each cylinder 13, 18 and 20 continues to operate in the reverse order of operation, thus completing the work.

According to the present invention, the operating cylinder 13 can be used to push the motor in a state where the pusher 19 is fixed to the moving plate 12, without using a separate actuator as the pushing means.

As described above, the clamping device of the present invention can constantly maintain the position of the motor even when the motor is temporarily fixed to the bracket, and can adjust the tension of the belt. Therefore, the belt is easily assembled to the motor unit, and the productivity of the motor unit is improved.

Although the present invention has been illustrated and described in detail with reference to its preferred embodiments, those skilled in the art will understand that without departing from the principles and scope of the present invention defined by the appended claims Various variations in form and detail are possible.
