Description

Technical Field

[0001] The utility model relates to the field of measuring tools, and more specifically, to a fast and high-precision tire steel wire angle measuring ruler. Background Art

[0002] The belt angle has an important impact on the safety performance, high-speed performance, comfort, etc. of the tire. During the design stage and mass production stage of the tire, each tire enterprise will take samples and analyze each batch of produced tires. Among them, the cross-section analysis is to analyze the dimensions of the internal skeleton materials, rubber materials, component distribution, etc. of the tire to verify whether the design is consistent with the actual production. Currently, when measuring the angle of the tire belt layer, tire enterprises usually dissect the tire and then use a protractor for measurement. This measurement method can only be carried out after dissecting the tire, resulting in a time-consuming and laborious test process, low test efficiency, and the shape of the belt layer steel wire peeled off from the dissected tire will change, deviating from the belt layer angle in the tire. For this reason, application number: CN201921928231.3 discloses a measuring device for the angle of the steel cord of the tire belt layer. The measuring device includes a semi-circular angle plate, a conductive line, a measuring arm, and a multimeter. The semi-circular arc edge of the semi-circular angle plate is a resistance material with uniform conductivity. The conductive line is installed on the central axis of the semi-circular angle plate. The top end of the conductive line is connected to the central part of the resistance material. The first conductive column is installed on the back of the semi-circular angle plate, and the first conductive column is connected to the bottom end of the conductive line. The bottom end of the measuring arm is rotatably installed at the center of the semi-circular angle plate. The measuring arm is provided with a section of conductive material that contacts the resistance material. A second conductive column is installed on the measuring arm, and the second conductive column is connected to the conductive material. The two measuring contacts of the multimeter can be respectively connected to the central part of the resistance material and the conductive material. This measuring device saves time and effort, has high test efficiency, and high measurement accuracy.

[0003] However, the above solution still has certain defects. The inventor has found through research that in the above solution, during the measurement process, it is necessary to make the first conductive column closely adhere to the cutting surface of the tire cross-section to ensure the position of one end of the measured steel wire, and then the second conductive column is used to find the other end of the steel wire to determine the positions of both ends of the steel wire and measure the steel wire angle. However, the user needs to hold the entire device and the tire end face with one hand at the same time and keep them closely attached, and rotate the measuring arm with the other hand for measurement. During the measurement process, it is very likely that due to the user's limb movement, relative displacement will occur between the device and the tire end face, resulting in the separation of the first conductive column from the measured steel wire, which may reduce the measurement efficiency and accuracy.

Specific embodiments

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a rapid and high-precision tire steel wire angle measuring ruler, including a placement plate 1. Both ends of one side of the upper surface of the placement plate 1 are provided with sliding holes, and each sliding hole is slidably connected with a guiding slide bar 101. One end of each of the two guiding slide bars 101 is fixedly connected to one side of the bottom surface of the N-shaped clamping plate 102. The other end of each guiding slide bar 101 is integrally provided with a limiting plate 103. The outer part of each guiding slide bar 101 located below the placement plate 1 is sleeved with a clamping spring 104. Both ends of each clamping spring 104 are respectively fixedly connected to one side surface of the corresponding limiting plate 103 and the bottom surface of the N-shaped clamping plate 102. A measurement component 2 is arranged between the inner walls on both sides of the N-shaped clamping plate 102.

[0023] Please refer to Figure 4 and Figure 5, the measuring component 2 includes a semi-circular scale plate 201. A measuring arm 202 is rotatably installed at the center of one side surface of the semi-circular scale plate 201. On the other side surface of the semi-circular scale plate 201, a holding plate 203 is integrally provided at one side. Both ends of the holding plate 203 are fixedly connected to the inner walls on both sides of the N-shaped clamping plate 102. A conductive contact 204 is provided on the holding plate 203. A power supply 205 is fixedly installed on one side surface of the measuring arm 202. A measuring brush 206 is also slidably connected to the end of the measuring arm 202 away from the semi-circular scale plate 201. The conductive contact 204, the power supply 205, and the measuring brush 206 are connected in series electrically.

[0024] Closely abut one side surface of the tire end face 5 against one side surface of the holding plate 203. After the conductive contact 204 contacts one end of a steel wire in the steel wire layer of the tire end face 5, rotate the measuring arm 202 to drive the displacement of the measuring brush 206. When the measuring brush 206 contacts the other end of the corresponding steel wire, at this time, the series circuit of the conductive contact 204, the power supply 205, and the measuring brush 206 is connected, then the position of the measuring steel wire can be quickly determined. At this time, the angle of the corresponding steel wire can be determined through the scale line set on the surface of the semi-circular scale plate 201 and the position of the measuring arm 202.

[0025] Furthermore, an indicator light 207 and a buzzer alarm 208 are also provided on one side surface of the measuring arm 202 on the side of the power supply 205. The indicator light 207 and the buzzer alarm 208 are connected in series electrically with the conductive contact 204, the power supply 205, and the measuring brush 206.

[0026] When the conductive contact 204 and the measuring brush 206 simultaneously contact both ends of a steel wire and the circuit is connected, the indicator light 207 and the buzzer alarm 208 give out sound and light prompts, thereby reminding the user to determine the position of the steel wire. The angle of the steel wire can be determined by observing the position of the measuring arm 202 and the corresponding scale on the surface of the semi-circular scale plate 201.

[0027] Furthermore, a sliding groove 209 is opened on one side surface of the measuring arm 202. A sliding column 210 is slidably connected in the sliding groove 209. One end of the sliding column 210 is fixedly connected to a mounting plate 211. The measuring brush 206 is fixedly installed on one side surface of the mounting plate 211.

[0028] The measuring brush 206 can adjust its relative position following the displacement of the sliding column 210 in the sliding groove 209, so as to adapt to tire end faces 5 of various widths and reduce the limitations in use.

[0029] Furthermore, the conductive contact 204 is fixedly installed on a mounting seat 212. The mounting seat 212 is slidably installed in an N-shaped sliding groove 213. The N-shaped sliding groove 213 is opened on one side surface of the holding plate 203.

[0030] The conductive antenna 204 can adjust its position in the N-shaped chute 213 following the mounting seat 212, so as to be applicable to the steel wire layer in the tire end face 5 of different heights. A damping structure can be arranged outside the mounting seat 212, which can make the mounting seat 212 hover at a certain height in the N-shaped chute 213 without external force, improving the stability during use.

[0031] Furthermore, a reading groove 214 is formed at a position corresponding to the scale line area of the semi-circular scale plate 201 on one surface of the measuring arm 202.

[0032] Through the reading groove 214, the rotation angle of the measuring arm 202 can be read more quickly and accurately, so as to determine the angle of the steel wire, improving the convenience during use.

[0033] Please refer to Figure 2 , the placing plate 1 is connected to a lifting mechanism 3 on one side. The lifting mechanism 3 includes a column 301, the column 301 is fixedly installed on the top surface of the base 4, a lifting chute 302 is formed on one surface of the column 301, a slider 105 is slidably installed in the lifting chute 302, the slider 105 is integrally arranged on one surface of the placing plate 1, a threaded hole 106 is formed through one surface of the slider 105, an adjusting screw 303 is threadedly connected in the threaded hole 106, one end of the adjusting screw 303 is rotatably installed on the top surface of the base 4, and the other end of the adjusting screw 303 extends outside the lifting chute 302 through a through hole and is provided with an adjusting knob.

[0034] By rotating the adjusting screw 303, the slider 105 can be adjusted to slide in the lifting chute 302. Rotating the adjusting screw 303 in different directions realizes the overall lifting of the placing plate 1, so as to be flexibly adjusted according to the user's habit and the actual test situation, reducing the limitations during use.

[0035] Working principle: First, adjust the overall height of the placement plate 1 by rotating the adjustment screw 303. Then, pull up the N-shaped clamping plate 102 to compress the clamping spring 104, and place the tire end face 5 to be measured between the placement plate 1 and the N-shaped clamping plate 102. After releasing the N-shaped clamping plate 102, under the elastic action of the clamping spring 104, the N-shaped clamping plate 102 drops to tightly press the tire end face 5 against the surface of the placement plate 1 for fixed limit, avoiding affecting the test accuracy due to the displacement of the tire end face 5 during the measurement process. Subsequently, push the tire end face 5 towards the abutment plate 203 until one side surface of the tire end face 5 abuts against the surface of the abutment plate 203, and make the conductive contact 204 contact one end of a steel wire in the steel wire layer of the tire end face 5. Then, adjust the position of the measuring brush 206 by sliding the sliding groove 209 according to the overall width of the tire end face 5, and then rotate the measuring arm 202 to drive the displacement of the measuring brush 206. When the measuring brush 206 contacts the other end of the corresponding steel wire, the circuit is connected at this time, and the indicator light 207 and the buzzer alarm 208 give out sound and light prompts. The user can determine the angle corresponding to the steel wire by observing the scale line set on the surface of the semi-circular scale plate 201 through the reading slot 214. Placing the tire end face 5 on the placement plate 1 and limiting the tire end face 5 by the N-shaped clamping plate 102 can free one hand of the user. The user can measure the angle of the steel wire in the tire end face 5 more stably with both hands operating the measuring assembly 2, improving the measurement accuracy.

[0036] It should be noted that the specific model specifications of the power supply 205, the measuring brush 206, the indicator light 207 and the buzzer alarm 208 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0037] The power supply of the power supply 205, the measuring brush 206, the indicator light 207 and the buzzer alarm 208 and its principle are clear to those skilled in the art and will not be elaborated here.

[0038] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
