Abstract

An apparatus for adjusting the position of a motor and for preventing the motor from being inclined when a belt is assembled to a motor assembly. The apparatus has a pulling section for pulling the motor and a pushing section for pushing the motor. The pulling section has a finger which grips the motor and pivots by a pneumatic cylinder. The pushing section pushes the motor against a pulling force of the pulling section so that the pivot movement or inclination of the motor can be prevented. The belt is easily assembled to the motor assembly, and the productivity of the motor assembly is increased.

Description

Be used for belt is assemblied in the holding motor device of motor sub-assembly

The present invention relates to a kind of device that is used to assemble the motor's for washing machine assembly, the particularly a kind of Dou of being used for belt is assemblied in the device of motor's for washing machine assembly.

Be used to drive be wrapped in the belt on the belt pulley that is connected in motor shaft motor should with accept driven member from the actuating force of motor by belt and be properly spaced and come.At this moment, install to such an extent that can stably drive driven member in order to make motor, the tension force of belt should be paid attention to.Fig. 1 shows the motor sub-assembly of washing machine.In the drawings, motor 1 and all be fixed in support 4 by the clutch 3 of motor driven by belt.Support 4 is fixed in the bottom surface of turning barrel (not shown).In the motor sub-assembly of washing machine, before belt 2 was assemblied in motor 1, motor 1 injected the bolt hole 7 of supports 4 and temporarily is installed in support 4 by the slotted eye 6 that simply bolt 8 is passed flange standing part 5.Under this state, belt 2 is assemblied in motor 1, and the motor 1 of fit on belt 2 is seated on the platform so that be sent to the automatic coupling arrangement of bolt.After this, motor 1 is connected in support 4 regularly by clamping bolt 8.At this moment, consider the tension force of belt 2, should suitably keep certain distance between motor 1 and the support 4.

But, as shown in Figure 1, before bolt 8 tightened up fully, motor 1 was owing to the effect of belt 2 tension force is tilted.Therefore, when bolt 8 tightened up fully, the position of motor 1 just was changed, so that the tension force of belt 2 also has been changed.

The present invention is intended to overcome the problems referred to above of the prior art, therefore the purpose of this invention is to provide a kind of holding motor device, and whereby, the position of motor accurately and is stably kept.

For achieving the above object, the invention provides a kind of holding motor device.This device comprises the pushing part that is used to withstand the traction element of belt tension traction motor and is used to withstand the tractive effort pushing motor of traction element, causes revolution with a pair of active force that tractive effort and belt tension were produced that prevents traction element.

According to the present invention, this device has and is used for supporting traction and pushes two-part supporting part.The installation site of motor can be by holding motor by traction and pushing two parts, and regulated by mobile support on forward and backward directions part.

According to the present invention, the motor that temporarily is fixed in support can be erected on the stand up position, and tension force belt can accurately be regulated so the installation site of motor can keep constant.

Above-mentioned purpose of the present invention and other every advantages by explaining the one preferred embodiment with reference to appended each figure, will become more apparent, in the accompanying drawing:

Fig. 1 is the partial cross sectional views of temporary transient installment state that shows the motor's for washing machine assembly a kind of commonly used of prior art;

Fig. 2 is the perspective view that shows the device for clamping of belt transmission motor of the present invention;

Fig. 3 showed before the device for clamping load motor, the partial sectional view of the claw of device for clamping as shown in Figure 2 action;

Fig. 4 shows at device for clamping after the load motor, is shown in the partial sectional view of claw action of the device for clamping of Fig. 2;

Fig. 5 is the partial cross sectional views that shows by the motor of as shown in Figure 2 device for clamping clamping.

After this, a preferred embodiment of the present invention will be described.In each figure, same part has same label.

Fig. 2 shows the device for clamping of a kind of belt transmission motor of a preferred embodiment of the present invention.In the drawings, device for clamping comprises buck plate 10; Guide rail 11 forms on buck plate 10; And movable plate 12, be bearing in slidably on the guide rail 11.Movable plate 12 is made it to move on forward and backward directions by operation cylinder 13, and cylinder 13 is contained on the buck plate 10.Retainer 14 is fixed on the buck plate 10, and can prevent that movable plate 12 breaks away from buck plate 10.

Claw

15 and 16 is contained on movable plate 12 and the connecting plate 17 pivotly.Connecting plate 17 is connected in claw cylinder 18 to

claw

15 and 16 and is made it to move on forward and backward directions by claw cylinder 18.Claw cylinder 18 be loaded on the bottom surface of movable plate 12 and on forward and backward directions mobile connecting plate 17, thereby mobile claw 15 and 16.When motor 1 was clamped by

claw

15 and 16, the top of motor 1 was by propeller 19 pushings.Propeller 19 is fastened on the propulsion cylinder 20 on the buck plate 10, and is made it to move on forward and backward directions by propulsion cylinder 20.

Below, explanation is met the operation of the holding motor device of the preferred embodiment of the present invention.

With reference to Fig. 3, when motor 1 during by conveyer belt (not shown) feeding device for clamping, claw cylinder 18 is passed connecting plate 17 towards motor 1.At this moment,

claw

15 and 16 oppositely pivots each other, so that motor 1 can be received between the end 15a and 16a that is placed on them.

Under this state, as shown in Figure 4, when movable plate 12 was made it to move forward by operation cylinder 13, motor 1 was placed among the space that is formed between claw 15 and 16.Under this state, claw cylinder 18 turns back to its initial position, and simultaneously, propulsion cylinder 20 comes into operation.When claw cylinder 18 had returned its initial position,

claw

15 and 16 end 15a and 16a pivoted towards its initial position as shown in phantom in Figure 2, thereby clamp motor 1.At this moment, as shown in Figure 5, claw 15 contacts a side 1a of motor 1 with 16, thereby with a side 1a of predetermined tractive effort traction motor 1, propeller 19 is the opposite side 1b by propulsion cylinder 20 pushing motors 1 then.

At this moment, because the inclination of the motor that a pair of active force caused 1 that

claw

15 and 16 tractive effort and belt 2 tension force are produced, the pushing point of 19 pairs of motors 1 of propeller should be lower than the end 15a of

claw

15 and 16 and the 16a contact point to motor 1 in order to prevent.Preferably,

claw

15 and 16 end 15a and the distance between 16a and the propeller 19 are equal to the width between motor 1 both sides 1a and the 1b.In the case, when the bolt that is used to assemble motor 1 was being tightened up, motor 1 was securely held.

That is motor 1 both sides 1a of Qing Xieing and 1b are made it standing vertically by the end 15a of

claw

15 and 16 and 16a and propeller 19 as shown in Figure 1.At this moment, the position of motor 1 can be regulated by control operation cylinder 13, so that the tension force of belt 2 also can be regulated.

After clamping bolt, each

cylinder

13,18 and 20 is unceasingly with opposite order of operation running, thus the end operation.

According to the present invention, operation cylinder 13 can be used for pushing motor under propeller 19 is fixed in the state of movable plate 12, need not use independent actuator as pressing device.

The above even device for clamping of the present invention also can keep the position of motor consistently when motor temporarily is fixed in support, and can regulate the tension force of belt.Therefore, belt is assemblied in motor sub-assembly easily, and the productivity ratio of motor sub-assembly is improved.

Though the present invention is at length illustrated and is illustrated with reference to its preferred embodiment, but technical staff in the art will be understood that, under the prerequisite that does not depart from the principle of the present invention that limits by appended every claim and scope, can carry out various distortion in form and details.
