Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tire balancer device, and more particularly to a device provided with a scale so that a required accurate fastening of a weight can be performed.

(Prior Art) The tire of a vehicle must be perfectly balanced around the axle, and if the tire is in an unbalanced state, it acts as a large centrifugal force even at a small amount of unbalance at high speed rotation. . This centrifugal force not only causes the tire to wear early but is also dangerous in the driving operation, and is therefore used in a perfectly balanced state.
By the way, the tire and the wheel on which the tire is mounted are
Since it is not perfectly balanced at the time of manufacture and assembly, the imbalance is corrected with the tire balancer device before it is mounted on the vehicle. Here, although detailed description of the tire balancer device is omitted, generally, the rotating main shaft is rotatably supported by bearings installed at two places with a certain distance, and a tire is attached to the tip of the rotating main shaft. The centrifugal force generated due to the unbalance amount due to the rotation is measured by the both bearing portions, and the desired unbalance amount is detected. Since the amount of imbalance is displayed separately on the inside and outside of the tire, the weight of the displayed weight is fixed to a predetermined position. By the way, since the weight to be fixed is marked on the surface thereof, the weight having the weight displayed on the display panel is selected and fixed.

However, since the weight is made of a relatively soft metal, it may be partially chipped or the markings displayed may be unclear, so the weight of the weight must be measured when fastening. There are many cases. Of course,
It is safer to double-check the weight of the weight, even if the weight is clear and there is no partial damage. Therefore, the operator has to check the weight each time by checking the weight, but going to the place where the above-mentioned scale is placed poses a problem that the work is interrupted, and at the same time reduces the work efficiency. It's very troublesome. Sometimes the scale is often out of place.

(Purpose of the present invention) When the unbalance of the tire is thus measured and the weight having the necessary weight is fixed to the predetermined position, there is the above-mentioned problem in the weight confirmation of the weight. The present invention is intended to solve these problems, and provides a balancer device having a balance installed.

(Structure of the Invention) The tire balancer device of the invention is a device to which a scale is attached. Here, the type of the scale is not limited, but a scale with a small measurement error is used to obtain an accurate balance, and the measurement value is displayed on the display panel. The display panel displays other measurement operation procedures, the measured unbalance amount, the place where the weight is fixed, sometimes the weight charge and the measurement charge, and the type thereof is arbitrary. The tire balancer device is composed of a main body and a display panel, the display panel is installed on the upper portion of the main body, and the rotating main shaft projects from the side surface of the main body. The rotating main shaft is rotatably supported by bearings installed at predetermined intervals in the main body, and is configured to rotate in conjunction with a motor mounted in the main body. These structures are the same as those of the conventional balancer device.

Embodiments according to the present invention will be described below in detail with reference to the drawings.

(Embodiment) FIG. 1 is an embodiment showing a tire balancer device of the present invention, in which 1 is a main body, 2 is a display panel, 3 is a rotating spindle, and the display panel 2 is attached to the upper part of the main body 1. The rotary main shaft 3 horizontally projects from the side surface 4 of the main body 1. The rotating main shaft 3 is provided with a coupling 5, and the rotating main shaft 3 is pivotally supported by bearings installed in the main body 1. The bearings are provided at two places with a certain space, and the centrifugal force generated by the unbalance amount is detected as a reaction force acting on the bearing. A wheel with a tire for measuring the amount of unbalance is attached to the rotating main shaft 3 via a coupling 5, and the amount of unbalance is calculated based on the centrifugal force and the rotational speed generated by rotating at a predetermined speed. It is displayed on the display panel 2. Of course, the unbalanced part is also displayed at the same time, and the weight according to the displayed unbalanced amount is fixed to a predetermined part, but the balancer device of the present invention is provided with a scale, You can check the weight of the weight before fastening. The scale 6 is installed in a recessed space 8 formed on the front surface 7 of the main body 1, and a receiving tray 9 is provided in the recessed space 8 and a weight to be weighed is placed on the receiving tray 9.

The installation location of the scale 6 is not limited to the front surface 7 of the main body 1 and may be the top surface 10. However, a highly accurate and stable scale 6 is suitable. Therefore, a weight having a weight corresponding to the unbalanced weight displayed on the display panel 2 is selected, and after confirming whether or not the weight imprinted on the weight is correct, the weight is fixed to a predetermined position. Since the correct weight of the weight measured by the scale 6 is displayed on the display panel 2, the weight can be confirmed. Of course, after fixing, the measurement is performed again to confirm the balance state, and the work is completed when the imbalance is within the allowable value.

As described above, the tire balancer device of the present invention is
A scale for measuring the weight weight for fastening is set and the weight weight measured by the scale is displayed on the display panel, and the following effects can be obtained.

(Effect) (1) Since the balancer is set in the tire balancer device of the present invention and the weight weight can be confirmed before being fixed to the wheel, it is very convenient. By checking the weight weight in this way, it is possible to fix the weight correctly at all times, so the balance confirmation measurement with the weight fixed is almost satisfied, and the labor of converting the weight and re-measuring it is not necessary. Lost. That is, the unbalance measurement work and the weight fastening work can be performed more efficiently.

(2) Since the balance is attached to the main body of the balancer device, it does not separate from the device, the weight can be measured at any time as needed, and the inconvenience of searching for a balance is eliminated. Therefore, the measurement of weight before fastening is standardized, and as a result, it is possible to provide a wheel with tires that is balanced with higher accuracy.
