Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel balancer for inspecting the weight balance of wheels of a vehicle and adjusting the problems thereof. , Simply referred to as "wheel") and fitted and mounted to a wheel balancer wheel mounting device.

[0002]

2. Description of the Related Art Conventionally, a wheel is manually carried and moved on a wheel mounting shaft of a wheel balancer at a predetermined height on the floor, or a wheel is lifted to a suitable height by an appropriate lift and fitted. The mounting was done by mounting.

[0003]

When the wheel balancer detects the unbalance of the weight balance of the wheel and makes a predetermined adjustment, the wheel mounting shaft is fitted and fitted with the axle hole of the wheel accurately. It is necessary to be aligned. However, the conventional means as described above lacks appropriate means for aligning the wheel mounting shaft of such a wheel balancer with the axle hole of the wheel, and the wheel mounting shaft depends on the type of wheel. Since the wheels are at a certain height above the floor and have a considerable weight, it takes a lot of time and effort to perform the alignment and is difficult, resulting in not only poor installation work efficiency but also sometimes There was a problem that the taper surface and the like of the wheel mounting shaft of the wheel balancer was damaged during the alignment. Therefore, the present invention raises the wheels having different diameters which are preliminarily positioned in the left-right and up-down directions with respect to the wheel mounting shaft of the wheel balancer at the time of installation of the device and are arranged at predetermined positions via the elevating means, When the center of the axle hole of the wheel reaches the same height as the axis of the wheel mounting shaft of the wheel balancer, the ascent of the wheel is automatically stopped, and at the same time, the driving of the lifting means is automatically stopped. By this, the centering of the wheel mounting shaft and the wheel axle hole can be automatically, quickly, easily and surely performed.
It is an object of the present invention to provide a wheel mounting device for a wheel balancer which can solve the above-mentioned problems of the prior art.

[0004]

In order to solve the above problems and achieve the object, the present invention has the constitutions of claims 1 to 4. These are common in that wheels having different diameters are positioned in left and right and up and down with respect to the wheel mounting shaft of the wheel buncer in advance when the device is installed, and are arranged at predetermined positions. When the wheel is lifted through the wheel, when the center of the wheel axle hole reaches the same height as the axis of the wheel mounting shaft, the lift is automatically stopped or the driving of the lifting means is automatically stopped at the same time. They differ in terms of means.

According to the first aspect of the present invention, the lifting of the wheels through the elevating means is mechanically automatically stopped at the predetermined position, and the driving of the elevating means is appropriately stopped by the operator. That is, specifically, a pedestal that runs on a rail disposed on the floor facing the wheel mounting shaft of the wheel balancer, and a column that is vertically erected on the pedestal in a height-adjustable manner. Wheels with different diameters are slidably mounted on the stanchions and their axle holes are wheeled.
An upper wheel support and a lower wheel support that are supported in a state of standing upright on the wheel mounting shaft of the louver balancer, an elevation of the lower wheel support that supports the wheel, and a lowering of the upper wheel support that does not support the wheel. The upper and lower parts of the upper and lower wheel supports are synchronized to support the upper part of the wheel when the center of the axle hole of the wheel reaches the same height as the axis of the wheel mounting shaft. And a lowering means for moving the wheel supporting means of (1) to move in synchronization with each other along the column, and the lower wheel supporting means is a support rod holding type or a wheel for supporting the wheel by sandwiching a part of the lower part thereof. The supporting frame is mounted on the lower end while supporting it, while the upper wheel support is corresponding to the supporting rod holding type that supports the wheel with a part of its upper part supported or the wheel is supported on the upper end. Support frame mounting type or Characterized in that it was even without the rod contact form.

In the above structure, the wheel balancer
The lateral positioning of the wheels with respect to the wheel mounting shaft is performed in advance by setting a pedestal equipped with a wheel support and a rail for traveling the pedestal on the wheel balancer at the time of installation of the device. It For example, as shown in FIG. 4, an extension line of the center C1 of the lower wheel support and a wheel mounting shaft S of the wheel balancer (see FIGS. 1 and 3), which are slidably arranged on the support on the pedestal. The frame is arranged so as to be parallel to the extension of the axis in the vertical plane, and the frame is arranged so as to face the wheel mounting shaft S, and the position is set to the position of the traveling roller attached to both side ends of the frame. -Arranged so as to face the wheel mounting shaft S. Alternatively, since the distances L1 and L2 from the center C1 of the wheel support to the rails located at the left and right ends of the frame are constant, the distances L1 and L2 from the extension line of the axis of the wheel mounting shaft S to the left and right. Alternatively, the rail may be disposed opposite to the wheel mounting shaft, and the pedestal may be placed on the rail. The number of rails is not limited to two and may be one.

The vertical positioning of the wheel with respect to the wheel mounting shaft of the wheel balancer is also carried out in advance by adjusting the height of the column on the gantry when the apparatus is installed. Since the upper and lower wheel supports are slidably arranged vertically symmetrically with respect to the column and the upper and lower limit positions thereof are set, for example, as shown in FIG. This is performed by adjusting the height of the point C2 on the column, which is the midpoint of the position, to the height of the shaft center of the wheel mounting shaft S via an adjustment fitting. The wheel mounting shaft of the wheel balancer and the axle hole of the wheel are aligned with each other by vertically moving the upper and lower wheel supports, which are arranged at predetermined positions in the above-described positioning, through the elevating means along the column. This is done by moving them synchronously in the same direction. That is, in the lower wheel support described above,
The wheel is placed on the wheel mounting shaft of the wheel balancer so as to stand face-to-face, and the elevating means is driven to ascend along the column. Since the elevating means moves the lower wheel support on which the wheels are placed up and the upper wheel support that does not support the wheels down synchronously, the lower and upper wheel supports move from the lower and upper positions at the same time respectively. At the same distance, the center of the axle hole of the wheel supported by the lower wheel support reaches the position of point C2 on the column, that is, the same height as the axis of the wheel mounting shaft S. At the same time, the upper wheel support also becomes in a state of supporting the upper part of the wheel, and the raising of the wheel is automatically stopped by the support by the wheel support from the upper and lower parts, and thus the wheel mounting shaft of the wheel balancer and the wheel. It is aligned with the axle hole of. Then, by moving the gantry along the rail to the wheel balancer, the wheel can be smoothly attached to the wheel mounting shaft in the aligned state. It should be noted that the driving of the elevating means is appropriately stopped when the lifting of the wheels is stopped. Further, the support pillars that serve as guides for lifting the upper and lower wheel supports may be provided on the pedestal either as a single column or as a pair of opposing columns.

In the elevating means, for example, wires are wound in parallel between a pair of pulleys arranged at the upper and lower ends of a column, and the upper wheel support is attached to the wire on one side. The lower wheel supports are attached to the wires on the other side, and the piston rods of the cylinders are attached to the upper or lower wheel supports, and the expansion / contraction operation of the cylinder and the accompanying pulley are inserted. The above-mentioned wire support is used to move the upper and lower wheel supports synchronously in the vertical direction along the column. Alternatively, a sprocket may be used instead of the pulley, a chain may be used instead of the wire, and the sprocket may be rotated by a motor. Alternatively, using a three-bar linkage mechanism in which the upper arm and the lower arm are pivotally attached to the central arm,
Even if the central arm is pivotally attached to the strut by a rotating shaft, the upper arm and the lower arm are pivotally attached to the upper wheel support and the lower wheel support, respectively, and the upper or lower wheel support is provided with a cylinder. Good. Further, a pinion pivotally attached to a support via a rotary shaft and an upper rack and a lower rack that mesh with both side surfaces of the pinion opposite to each other by 180 degrees are used, and an upper wheel support and a lower wheel support are provided for the upper and lower racks, respectively. Fixed, and a cylinder is inserted in the upper or lower wheel support, etc.,
Any structure may be used as long as the upper and lower wheel supports can be vertically moved in synchronization with each other along the column.

The upper and lower wheel supports are used to support wheels having different diameters such that the axle holes thereof stand upright against the wheel mounting shaft of the wheel balancer. As will be described later, it is formed as a support rod holding type that supports the wheel while sandwiching a part of the upper and lower parts thereof, or a support frame mounting type that supports the wheel by contacting the upper and lower ends thereof. Since the wheels are supported from above and below in synchronization with the elevating means at the predetermined time, the same structure is used to support the wheels under the same conditions in both upper and lower parts. However, when a supporting frame mounting type supporting the lower end of the wheel is used as the lower wheel support for mounting the wheel and rising, the upper wheel support is synchronized with the wheel support. It is not limited to the supporting frame mounting type as long as it contacts the upper end, and a pressing rod abutting type that contacts the upper end of the wheel and supports it may be used. Then, in order to support the wheel so as to stand upright on the wheel mounting shaft of the wheel balancer, a support plate or a pipe for a stopper is provided on the back surface.

In the structure of claim 2, the structure of claim 1 automatically stops the lifting of the wheels at a predetermined position, but the driving of the lifting means for lifting the wheels is appropriately stopped. On the other hand, the drive is automatically stopped at the same time. That is, in this case, the upper wheel support is provided with a sensor that operates when the wheel support is in contact with the upper ends of the wheels in synchronism with the above to automatically stop the driving of the elevating means. is there. Since the above operation must be performed when the wheel mounting shaft of the wheel balancer and the axle hole of the wheel are aligned regardless of the difference in the diameter of the wheel, the lower wheel support does not contact the wheel with its lower end. A support frame mounting type that supports the same is used, and the upper wheel support tool also has the same shape or a pressing rod contact type that has similar support conditions. The other structure is the same as that of claim 1.

The structure of claim 3 is different from the structure of claim 2 in that it automatically stops the lifting of the wheels at the predetermined position and the driving of the lifting means, and is otherwise common. is there. Specifically, a pedestal that runs on a rail disposed on the floor facing the wheel mounting shaft of the wheel balancer, a column that stands upright on the pedestal, and slidable on this column And a wheel support member of a support frame mounting type for supporting wheels of different diameters in contact with their lower ends in a state in which the axle holes are upright facing the wheel mounting shaft of the wheel balancer. Elevating means for elevating and lowering the support along the pillar, and a predetermined distance such as a distance from the upper end of a wheel standing upright on the wheel support at the lower limit position to a predetermined position vertically above the position. And a wheel support that supports the wheel based on the measurement information of the predetermined distance are raised along the support pillar through the elevating means, and the center of the wheel axle hole is the axis of the wheel mounting shaft. When it reaches the same height as the heart The so allowed to stop, characterized by comprising a control means for controlling the driving of the elevating means.

In this case, as in the structure of claim 2,
By vertically moving the upper and lower wheel supports on which the wheels are placed together in the vertical direction through the elevating means along the support columns, the ascending and elevating means are automatically driven at the predetermined position where the centering is performed. It is not stopped by the control means so that the wheel support on which the wheels are placed is moved up along the support column through the elevating means to a predetermined distance in which the centering is performed according to its diameter. Since the drive of the raising and lowering means is automatically stopped,
The column that serves as an elevating guide for the wheel support does not necessarily need to be upright with respect to the frame so that the height can be adjusted. That is, when the device is installed, by performing the same operation as above, if the positioning of the wheels with respect to the wheel mounting shaft of the wheel balancer is preliminarily performed in the horizontal direction, the vertical positioning is automatically performed. ing. Further, since the wheel support does not need to support the wheels in the upright state in synchronism with each other in the vertical direction, it is not always necessary to dispose the upper wheel support,
It suffices to dispose only those corresponding to the above-mentioned lower wheel support for mounting and supporting the wheels in a standing state. However, by detecting the position of the upper end of the wheel standing upright on the wheel support at the lower limit position and measuring a predetermined distance related to that position,
Since the wheel ascending distance required for centering according to the diameter of the wheel is calculated based on the measured value to control the drive of the lifting device, the position of the lower end of the wheel supported by the wheel support is the wheel. Must be constant irrespective of the difference in the diameter of the wheel. Therefore, the wheel support is a support frame mounting type that supports the wheel by contacting its lower end.

As the elevating means, for example, a wire or a belt is wound in parallel between a pair of pulleys arranged at the upper and lower ends of a column, and a wheel support is attached to the wire or the belt. , A pulley is rotated by a motor, and a wheel support on which a wheel is mounted is moved up and down along a column as the wire or belt is rotated between the pulleys. Alternatively, the pulley is used as a sprocket, the wire or belt is used as a chain, the wheel support is attached to the chain, and the wheel support is pushed or pulled by a cylinder. It may be.

As the measuring means, for example, a slider type sensor slides on a scale, the amount of linear movement thereof is electromagnetically measured, the distance between them is measured, and the measured value is sent to the control means. An existing measurement unit for distance measurement, which is electrically input, is used. As the control means, for example, a micro computer is used. FIG. 7 shows an example of a control method of the predetermined ascending distance according to the diameter of the wheel required for the centering based on the measurement information by the measuring unit. In the figure, the support frame-mounted wheel support is slidably mounted on a column upright on a pedestal via a mounting frame having a guide roller. The pillar is upright on the pedestal, and a pair of pulleys are arranged at both upper and lower ends of the pillar, and the wires are separated from each other on both sides in the thickness direction of the pillar and are arranged in parallel lines along the vertical surface thereof. The mounting frame of the wheel support is fixed to one side of the wire, and the pulley at the upper end is connected to the rotating shaft of the motor. On the other hand, on the mount, the scale is placed at a position on the back side thereof which corresponds to the center of the wheel support.
A guide strut for measurement attached with a cable is upright, and the guide strut and wire connected to the motor are attached to this guide strut.
A slider-type sensor for distance measurement is disposed via a slider so as to be vertically movable from the upper limit position. H in the figure
The symbols h, r, a, x, y, m indicate the following distance dimensions. H: Distance from the upper limit position of the distance measuring sensor to the floor G h: Height from the axis of the wheel mounting shaft S of the wheel balancer to the floor G r: Radius of the wheel T a: Lower limit position Wheel T standing upright on a wheel support in
From the lower end of the wheel to the floor surface G; the ascending distance required to raise the wheel T until the center of its axle hole is at the same height as the axis of the wheel mounting shaft S of the wheel balancer. Required ascent distance) y; distance from the upper end of the wheel T to the upper limit position of the sensor for distance measurement m; distance from the upper end of the wheel T to the upper surface of the gantry However, for the centering according to the diameter of the wheel T The required ascent distance x is expressed by the following relational expression,
Since h, H, and a are all constant and can be made constant in advance, the distance y from the upper end of the wheel T to the upper limit position of the sensor for distance measurement can be easily calculated from the equation. It can be calculated and obtained. H = y + 2r + a ... h = x + r + a ... x = (1/2) y + {h- (1/2) H- (1/2) a} Here, {h- (1 / 2) H- (1/2) a} is a constant. Therefore, the sensor for distance measurement is lowered along the guide column through the rotation of the motor until it comes into contact with the upper end of the wheel T, and upon contact with the upper end of the wheel T, the sensor is used for the aforementioned measurement. By measuring the distance y and inputting the measured value to the control means, the control means calculates the ascending distance x necessary for centering the wheel T based on the input measured value by the above-mentioned arithmetic expression. The control means issues a control command to the motor by the calculation, rotates the motor and raises the wheel support on which the wheel T is placed along the support column, and when the ascending distance coincides with the above x, the motor is operated. Stop the drive. As a result, the center of the axle hole of the wheel T is at the same height (h) as the axis of the wheel mounting shaft S of the wheel balancer.
Since it will be stopped when it becomes, it means that the alignment has been done. The drive control of the motor is performed by controlling the number of revolutions of the motor. When the lifting / lowering means uses a cylinder that pushes or pulls the wheel support, the drive control is performed by adjusting the pressure of the pressure fluid.

In the calculation of the ascending distance required for the centering of the wheels, since the height of the pedestal from the floor surface is constant, instead of measuring the above y, from the upper end of the wheel T to the upper surface of the gantry. This can also be done by measuring the distance m of. The calculation formula is omitted. Further, in place of the measuring unit for measuring the distance, a rotary potentiometer is connected to the rotary shaft of the motor, and when the sensor descends from the upper limit position and comes into contact with the upper ends of the wheels T of the motor. Stop the rotation and turn the potentiometer
It is also possible to measure the wheel ascending distance necessary for the centering by detecting the rotation speed of the motor required for lowering the sensor by the motor.

According to the structure of claim 4, the structure of claim 3
The only difference is whether the lifting of the wheel support via the lifting means is performed using the support pillar as a guide, and the position of the upper end of the wheel standing upright on the wheel support at the lower limit position is detected and set at that position. Other common points are common, such as measuring a related predetermined distance, controlling the drive of the elevating means based on the measured information, and controlling the ascending distance required for centering the wheels. That is, specifically, a pedestal traveling on a rail disposed on the floor facing a wheel mounting shaft of a wheel balancer, and wheels having different diameters have wheel axle balancer wheels.
The wheel support which is of a supporting frame mounting type and which is supported by the lower end of the wheel support shaft in a state of standing upright against the wheel mounting shaft, and is mounted on the pedestal. The wheel support is mounted and lifted on the pedestal. The raising and lowering means for urging, the measuring means for detecting the position of the upper end of the wheel standing upright on the wheel support at the lower limit position and measuring a predetermined distance such as the distance from that position to a predetermined position vertically above the predetermined position, and the predetermined means. Based on the distance measurement information, the wheel support that supports the wheel is raised on the pedestal through the elevating means, and when the center of the wheel axle hole reaches the same height as the axis of the wheel mounting shaft, A control means for controlling the drive of the elevating means is provided so as to stop the ascending. As the raising and lowering means, for example, a cylinder is disposed in a pedestal with its base end pivotally attached in a vertically rotatable manner, and a pair of arms is attached to one end of the cylinder at the rod tip end. A suitable number of two-joint link mechanisms pivotally connected to each other are pivotally connected to each other, and the lower surface of the wheel support is supported on the other side free end side of the two-joint link mechanism. -While the wheel support can be moved up and down on the frame by the expansion and contraction operation of the link mechanism and the link mechanism.

It is supported in a standing upright position. Stopper plates 6d and 7d are attached to the support rods 6c and 7c so as to project them in order to support the wheels in the standing state. The upper and lower wheel supports 6, 7 slide on the support 4 in vertically symmetrical positions with respect to the point C2 so that they can be synchronously moved toward a fixed point C2 on the support 4 via the lifting means described later. The upper limit and the lower limit positions A and B are set as possible.

Reference numeral 8 denotes the upper and lower wheel supports 6,
It is an elevating means for vertically moving the 7 synchronously with each other along the column 4, and is composed of pulleys 8a, 8a, wires 8b and an air cylinder 8c. The pulleys 8a, 8a are arranged at the upper and lower ends of the support column 4 via mounting plates, and the wire 8b sandwiches the support column 4 between the pulleys 8a, 8a. It is wound on both sides in parallel along the length direction.

They are fixed to the other side of b, respectively. Reference numeral 9 is a turnbuckle for adjusting the tension of the wire 8b. One end of the turnbuckle 9 has a mounting frame 6a and the other end has a wire-8.
It is fixed to b.

When the above-mentioned device is installed opposite to the wheel balancer, the wheel disposition with respect to the wheel mounting shaft S of the wheel balancer is positioned in the left-right and up-down directions as described above. That is, similarly to the above, the positioning in the left-right direction is performed by the center of the lower wheel support 7 (see FIG.
And the pedestal 1 so that the extension line along the floor surface G at the center position of the U-shaped bent portion of the support rod 7c and the extension line in the axial direction of the wheel mounting shaft S are parallel to each other on the same vertical plane. Ray
The wheels 2 and 2 are disposed so as to face the wheel mounting shaft S. Next, in positioning in the vertical direction, the fixed point C2 (the middle point between the upper limit position A of the upper wheel support 6 and the lower limit position B of the lower wheel support 7 in FIG. 3) is the height of the axis of the wheel mounting shaft S. The height of the support column 4 standing upright on the pedestal 1 is adjusted via the height adjustment metal fitting 5 so as to match the height h.

When the wheel T is attached to the wheel mounting shaft S of the wheel balancer, first, the wheel T is placed upright between the U-shaped support rods 7c of the wheel support 7 at the lower limit position, and the wheel T is mounted between them. The lower part of T is clamped so that its rolling in the outer peripheral direction is restricted and is stable, and the stopper plate 7
The wheel T is supported via d via the wheel mounting shaft S such that its axle hole faces the wheel mounting shaft S. Then, the elevating means 8 is operated to move the upper wheel support 6 and the lower wheel support 7 along the support column 4 in the vertical direction in synchronization with each other. That is, compressed air is sent to the piston head side of the air cylinder-8c via a foot pedal (not shown) to extend the piston rod (direction X in FIG. 1) and the upper wheel support 6 that does not support the wheel T. Press down.

Then, since the upper wheel support 6 is fixed to one side of the wire-8b, the wire-8b is pulled up.

By the counterclockwise rotation of the wire 8b, the wire 8b descends and rises along the support column 4 toward the same point C2 at the same time and at the same distance, that is, in synchronization. Therefore, when the center of the axle hole of the wheel T that is placed on the lower wheel support 7 and is supported in the upright state and rises is at the same height as the midpoint C2, the U-shaped support rod 6c of the upper wheel support 6 is provided. Is in a state of sandwiching and supporting the upper portion of the wheel T, and the wheel T is stopped by the upper and lower wheel supports 6 and 7 from being vertically held in synchronization with each other, and the lifting thereof is stopped. The ascending / descending operation along the column 4 of 7 also stops at the positions D and E in FIG. The midpoint C2 is previously adjusted to the height of the shaft center of the wheel mounting shaft S of the wheel balancer when the device is installed. Therefore, by stopping the ascending of the wheel T, the center of the axle hole of the wheel T coincides with the height of the shaft center of the wheel mounting shaft S of the wheel balancer, and the alignment is achieved. The driving of the air cylinder-8c is appropriately stopped by the operator when the lifting of the wheels T is stopped. Then, from this state, the mount 1 is wheeled along the rails 2 and 2.
When the wheel T is run to the louver balancer, the wheel T can be smoothly fitted to the wheel mounting shaft S with its center aligned, and the wheel T can be removed from the upper and lower wheel supports and the wheel balancer. -Can be easily attached to.

After inspecting and adjusting the weight balance of the wheel T by the wheel balancer, the wheel T is supported by the upper and lower wheel supports 6 and 7, the pedestal 1 is returned to the original position, and the compressed air is supplied by the foot pedal. Is switched to the piston rod side of the air cylinder-8c to shorten the piston rod, and the upper wheel support 6 is pulled upward (direction Y in FIG. 1). Then, the wire-8b moves clockwise (arrow Y in FIG. 3).
3), the upper wheel support 6 and the lower wheel support 7 ascend and descend along the column 4 from the positions D and E of FIG. 3, respectively, and reach the upper limit position A and the lower limit position B and stop. . The drive of the air cylinder-8c is stopped and the wheel T is lowered. The upper and lower wheel supports 6, 7 are
In both cases, the U-shaped support rods 6c and 7c are used to drop the upper and lower parts of the wheel between them and to support them by sandwiching them so that their rolling in the outer peripheral direction is restricted and stable. It can be reliably supported regardless of the difference in the diameter of the wheel.
