Description

Digital depth gage measurement [0002]

The present invention relates to a digital depth gauge measuring instrument, and more particularly to a digital depth gauge measuring instrument comprising a sensor portion inserted in a groove of a tire and rolling in a circumferential direction, and a display portion displaying depth information of the groove measured by the sensor portion will be.

 The tire tread and the depth of the groove formed on the tread surface are correlated with each other and are related to the safety of the vehicle. When the depth of the groove falls below a certain depth due to the wear of the tread, the tire must be replaced. For this reason, a depth measuring device is conventionally inserted into a groove at one point on the tire tread surface to measure the depth of the groove.

However, if only the groove depth at one point on the tire tread surface is measured, it is difficult to know the depth only at that point. Therefore, if the depth of another point is known, the depth meter must be continuously moved and measured.

 Also, when measuring only the groove depth at one point on the tire tread surface, There is a problem in that the necessary information such as the deviation with respect to the depth of the groove within the predetermined section can not be well known.

Meanwhile, as a result of investigation of the prior art related to the present invention, several patent documents have been searched, and some of them will be described as follows.

Patent Document 1 is for measuring the dimensions of a precision forged molded product in which a plurality of grooves are formed therein, and includes: i) a frame; and ii) a guide member provided for reciprocating in the longitudinal direction of the frame, A moving table provided with a plurality of clamper members, iii) a positioning unit reciprocally movable upward and downward on the moving path of the moving table to determine an initial setting position of the forging part, iv) And a measuring unit for measuring a groove dimension inside the forged product by reciprocating in a vertical direction on the frame on the moving path of the moving table.

Patent Document 2 discloses a structure in which a minute metal sphere solidified in a spherical shape having a diameter of? 500 m or less is disposed at the tip of a contact probe which is in contact with an object to be measured, Dimensional coordinate measurement type measuring device using a contact probe that detects the position coordinates of the probe tip and measures the shape of the measured object by scanning the tip of the probe in contact with the measured object.

It is an object of the present invention to solve the problem of a depth gauge measuring device for measuring only one point in a groove of a tire and to provide a sensor which is inserted into the groove and moves within a predetermined section, A digital depth gauge measuring device capable of measuring and displaying a deviation in a circumferential direction according to a difference in depth within a predetermined section as well as an average depth of a groove within a predetermined section by displaying depth information within the predetermined section measured by the measuring section .

Another object of the present invention is to provide a digital depth gauge measuring instrument provided with a switch for precisely recognizing the start and end of measurement in a predetermined section of the display unit so that groove depth information within a predetermined section can be accurately measured.

In order to achieve the above object, a digital depth gauge measuring instrument according to the present invention is a measuring instrument for measuring tire groove depth information, comprising: a sensor unit which is inserted into a groove in contact with the tire tread surface and moves in a circumferential direction; And a display unit connected to the sensor unit and displaying depth information of the tire groove measured by the sensor unit.

The sensor unit includes a measuring device body having a contact surface contacting the tire tread surface; A depth sensor extending from the contact surface and inserted into the tire groove and moving up and down; And a roller integrally connected to the lower end of the depth sensor.

Preferably, the display unit includes an LCD window for digitally displaying depth information of the tire groove.

And a start and stop switch provided on the display unit to start and stop the measurement.

According to the digital depth gauge measuring apparatus of the present invention, in the method of measuring only the depth of one point of the existing groove, a method of measuring the depth in a predetermined section of the groove is selected, and the average result and the minimum and maximum deviation It is possible to grasp the depth information at a glance.

Further, by grasping the depth information at a glance, it is possible to more accurately measure the depth of the groove of the tire to be measured, and it is possible to easily grasp the specification error of the tire.

Hereinafter, preferred embodiments of a digital depth gauge measuring instrument according to the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

1 is a schematic block diagram of a digital depth gauge measuring instrument according to the present invention.

1, the digital depth gauge measuring apparatus according to the present invention comprises a sensor unit 1 for inserting into a groove in contact with a tread surface of a tire and a display unit 2 connected to the sensor unit 1, The sensor unit 1 is adapted to move in the circumferential direction in the groove.

The sensor unit 1 includes a bar type measuring instrument main body 3 having a contact surface 3a contacting one surface of the tire and a depth sensor 4 extending from the center of the contact surface 3a and inserted into the groove of the tire And a roller 5 integrally connected to the lower end of the depth sensor 4. The depth sensor 4 moves in the circumferential direction in the groove by the rolling motion of the roller 5 have. The display unit 2 is also provided with an LCD window 6 for digitally displaying the depth information of the inside of the groove of the tire measured by the sensor unit 1, that is, the minimum and maximum deviations of the average depth and depth in a certain section of the groove, And a start and end switch 7 is provided to select start and end of measurement of the depth information within a predetermined period of the groove.

A method of measuring the depth of a groove within a predetermined section by the digital depth gauge measuring instrument of the present invention is as follows.

The rollers 5 and the depth sensor 4 integrally formed at the starting point of the tire groove are inserted to allow the sensor unit 1 to be positioned and the contact surface 3a of the measuring unit body 3 of the sensor unit 1 ) Is in contact with the tread surface. In this state, after pushing the measurement start switch 7, the tire tread surface and the contact surface 3a of the measuring instrument body 3 are kept in close contact with each other to a desired end point within a predetermined interval of the tire groove, The end switch 7 is pressed before separating the roller 5 of the roller 1 from the groove. When the measurement of the groove depth information within the predetermined section is finished, the values of the minimum depth and the maximum depth of the groove in the predetermined section are displayed on the LCD window 6 of the display section 2, thereby measuring the desired section of the groove Results are obtained.

As described above, the digital depth gauge measuring instrument according to the present invention has been described with reference to the drawings. However, the present invention is not limited to the embodiments and drawings disclosed in the present specification, It should be understood that various modifications may be made by those skilled in the art.
