Description

Technical Field

[0001] The utility model relates to the field of track shoe detection tools, and more specifically, to a hot-rolled single-tooth track shoe leg shape detection tool. Background Art

[0002] Track shoes are one of the chassis parts of construction machinery and are commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Track shoes are divided into single-tooth track shoes, double-tooth track shoes, and triple-tooth track shoes according to their shapes. Single-tooth track shoes are mainly used to make bulldozer track chains.

[0003] During the hot rolling process of the single-tooth track shoe, with the increase in rolling volume and the aging of the rollers, the long legs and short sides of the single-tooth track shoe steel are prone to surface quality problems such as lack of meat, roller marks and pits, resulting in dimensional deviations. When this happens, it is difficult to visually detect with tools such as rulers and vernier calipers. It is necessary to use a band saw to cut a sample of the single-tooth track shoe and compare it with the finished product image. The judgment time is long, which affects production efficiency and is prone to waste. Utility Model Content

[0004] The utility model aims to overcome the defects of the above-mentioned prior art and provide a hot-rolled single-tooth track shoe leg shape detection tool, which is used to solve the technical problem that a band saw is needed to cut a single-tooth track shoe sample and then compare it with a finished product image, which takes a long time to judge and affects production efficiency.

[0005] The technical solution adopted by the utility model is a hot-rolled single-tooth track shoe leg shape detection tool, comprising a horizontal section and a vertical section, the horizontal section is connected to the vertical section and is integrally formed; the horizontal section is provided with a detection groove one and a detection groove two, the width of the detection groove one gradually increases from the inside to the outside, and the two side walls of the detection groove one are mirror images of each other; the inclination degree of the inner side wall of the detection groove two close to the detection groove one is less than the inclination degree of the inner side wall of the detection groove two away from the detection groove one, and the depth of the detection groove two is less than the depth of the detection groove one.

[0006] During the inspection, the inspection groove one is plugged into the long leg of the single-tooth track shoe, and the inspection groove two is plugged into the short side of the single-tooth track shoe. Through the distance between the shape of the long leg of the single-tooth track shoe and the inner wall of the inspection groove one, and the distance between the shape of the short side of the single-tooth track shoe and the inner wall of the inspection groove two, it can be quickly judged whether the shapes of the long leg and the short side of the hot-rolled single-tooth track shoe are qualified, thereby reducing the measurement time and improving the production efficiency.

[0007] Furthermore, the bottom width of the detection groove 1 is 1-2 mm larger than the width of the end of the long leg of the single-tooth track shoe. The detection groove 1 is used to detect the shape of the leg end of the long leg of the single-tooth track shoe. The slopes of the two side walls of the detection groove 1 are respectively the same as the slopes of the two side walls of the long leg of the single-tooth track shoe, and can quickly detect whether the shape of the leg end of the hot-rolled single-tooth track shoe is within the tolerance range.

[0008] Furthermore, the bottom width of the second detection groove is 1-2 mm larger than the short side width of the single-tooth track shoe. The second detection groove is used to detect the short side shape of the single-tooth track shoe, and the slopes of the two side walls of the second detection groove are respectively the same as the slopes of the two side walls of the short side of the single-tooth track shoe, so as to quickly detect whether the short side end shape of the hot-rolled single-tooth track shoe is within the tolerance range.

[0009] Furthermore, the thickness of the horizontal section is 5-8 mm. When the thickness is less than 5 mm, the horizontal section is thin, and it is difficult to keep it perpendicular to the shape of the single-tooth track shoe during detection, which will cause measurement errors. When the thickness is greater than 8 mm, the horizontal section is thick, and it is difficult to observe the distance between the long leg shape and the detection slot 1, and it is not easy to measure. When the thickness is 5-8 mm, both can be taken into account at the same time.

[0010] Furthermore, the vertical section is rectangular, with a width of 30-40 mm and a length of 100-120 mm. The vertical section is used for hand-holding or receiving other handles, etc., to facilitate hand-holding detection.

[0011] Furthermore, the depth of the detection groove 1 is 1-2mm less than the height of the long leg of the single-tooth track shoe, and the depth of the detection groove 2 is 1-2mm less than the height of the short side of the single-tooth track shoe. Only when the depth difference between the detection groove 1 and the long leg is the same as the depth difference between the detection groove 2 and the short side, can the plug-in detection be performed, otherwise one side will be blocked and cannot be measured. The height difference is mainly set to prevent the height change of the long leg and the short side of the single-tooth track shoe from interfering with the detection of the detection groove 1 and the detection groove 2.

[0012] Furthermore, the intersections of the inner side wall and the bottom wall of the detection slot 1 and the intersections with the two sides of the external port are all chamfered, and the intersections of the inner side wall and the bottom wall of the detection slot 2 are chamfered. The chamfers are provided mainly to match the chamfers on the long legs and the short sides to prevent interference during detection.

[0013] Furthermore, the radius of the rounded corner is 1-2 mm. The size of the rounded corner is the same as the tolerance when detecting the long leg and short side shapes, so as to facilitate overall observation and prevent interference during detection.

[0014] Furthermore, the two side walls of the detection slot 1 are chrome-plated. Because the detection slot 1 is relatively narrow and long as a whole, when inserted into the long leg, friction between the two side walls of the detection slot 1 and the long leg is inevitable. Under long-term friction, the width of the detection slot 1 will gradually increase, thus causing detection errors. The chrome plating mainly increases the wear resistance of the two side walls of the detection slot 1, thereby reducing its detection error and increasing its service life.

[0015] Furthermore, the horizontal section and the vertical section are made of carbon steel, tool steel or stainless steel. Carbon steel has the characteristic of low cost, while tool steel and stainless steel have high wear resistance and do not even require chrome plating, and have high measurement accuracy, but the cost is relatively high.

[0016] Compared with the prior art, the utility model has the following beneficial effects: during detection, the detection groove one is plugged into the long leg of the single-tooth track shoe, and the detection groove two is plugged into the short side of the single-tooth track shoe. By using the distance between the outer shape of the long leg of the single-tooth track shoe and the inner wall of the detection groove one, and the distance between the outer shape of the short side of the single-tooth track shoe and the inner wall of the detection groove two, it is possible to quickly determine whether the outer shapes of the long legs and short sides of the hot-rolled single-tooth track shoe are qualified, thereby reducing the measurement time and improving the production efficiency.

[0022] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0023] like Figure 1-4 As shown, the present scheme discloses a hot-rolled single-tooth track shoe leg shape detection tool, including a horizontal section 4 and a vertical section 3, the horizontal section 4 is connected to the vertical section 3 and formed in one piece; a detection groove 1 and a detection groove 2 are arranged on the horizontal section 4, the width of the detection groove 1 gradually increases from the inside to the outside, and the two side walls of the detection groove 1 are mirror images of each other; the inclination degree of the inner side wall of the detection groove 2 2 close to the detection groove 1 is less than the inclination degree of the inner side wall of the detection groove 2 2 away from the detection groove 1, and the depth of the detection groove 2 2 is less than the depth of the detection groove 1.

[0024] The bottom width of the detection groove 1 is 1-2 mm larger than the width of the end of the long leg 6 of the single-tooth track shoe 5. The detection groove 1 is used to detect the shape of the leg end of the long leg 6 of the single-tooth track shoe 5. The slopes of the two side walls of the detection groove 1 are respectively the same as the slopes of the two side walls of the long leg 6 of the single-tooth track shoe 5, and can quickly detect whether the shape of the leg end of the long leg 6 of the hot-rolled single-tooth track shoe 5 is within the tolerance range.

[0025] The bottom width of the detection groove 2 is 1-2 mm larger than the width of the short side 7 of the single-tooth track shoe 5. The detection groove 2 is used to detect the shape of the short side 7 of the single-tooth track shoe 5. The inclinations of the two side walls of the detection groove 2 are respectively the same as the inclinations of the two side walls of the short side 7 of the single-tooth track shoe 5, and can quickly detect whether the shape of the end of the short side 7 of the hot-rolled single-tooth track shoe 5 is within the tolerance range.

[0026] The thickness of the horizontal section 4 is 5-8 mm. When the thickness is less than 5 mm, the horizontal section 4 is thinner, and it is difficult to keep it perpendicular to the shape of the single-tooth track shoe 5 during detection, which will cause measurement errors. When the thickness is greater than 8 mm, the horizontal section 4 is thicker, and it is difficult to observe the distance between the shape of the long leg 6 and the detection groove 1, and it is not easy to measure. When the thickness is 5-8 mm, both can be taken into account at the same time.

[0027] The vertical section 3 is rectangular, with a width of 30-40 mm and a length of 100-120 mm. The vertical section is used for hand-holding or receiving other handles, etc., to facilitate hand-holding detection.

[0028] The depth of the detection groove 1 is 1-2mm smaller than the height of the long leg 6 of the single-tooth track shoe 5, and the depth of the detection groove 2 is 1-2mm smaller than the height of the short side 7 of the single-tooth track shoe 5. Only when the depth difference between the detection groove 1 and the long leg 6 is the same as the depth difference between the detection groove 2 and the short side 7, can the plug-in detection be performed, otherwise one side will be blocked and cannot be measured. The height difference is mainly set to prevent the height change of the long leg 6 and the short side 7 of the single-tooth track shoe 5 from interfering with the detection of the detection groove 1 and the detection groove 2.

[0029] The intersection of the inner side wall and the bottom wall of the detection slot 1 and the intersection of the two sides of the external port are all chamfered, and the intersection of the inner side wall and the bottom wall of the detection slot 2 is chamfered. The chamfer is set mainly to match the chamfers on the long leg 6 and the short side 7 to prevent interference during detection. The radius of the chamfer is 1-2mm. The size of the chamfer is the same as the tolerance when detecting the shape of the long leg 6 and the short side 7, so as to facilitate overall observation and prevent interference during detection.

[0030] The two side walls of the detection slot 1 are chrome-plated. Because the detection slot 1 is relatively narrow and long as a whole, when it is inserted into the long leg 6, friction between the two side walls of the detection slot 1 and the long leg 6 is inevitable. Under long-term friction, the width of the detection slot 1 will gradually increase, so detection errors will occur. Chrome plating mainly increases the wear resistance of the two side walls of the detection slot 1 to reduce its detection error and increase its service life.

[0031] The horizontal section 4 and the vertical section 3 are made of carbon steel, tool steel or stainless steel. Carbon steel has the characteristic of low cost, while tool steel and stainless steel have high wear resistance and do not even require chrome plating, and have high measurement accuracy, but the cost is relatively high.

[0032] The size of the detection groove 1 is L1 = L3 + 2mm, the size of the detection groove 2 is L2 = L4 + 2mm, the groove bottom depth of the detection groove 1 is H1 = H3 + 2mm, and the groove bottom depth of the detection groove 2 is H2 = H4 + 2mm; when measuring the shape of one side (i.e. the right side) of the single-tooth track shoe 5, if Figure 3 As shown, the detection groove 1 is fitted with the leg end of the long leg 6 of the single-tooth track shoe 5, and the right side walls of the detection groove 1 and the detection groove 2 are fitted with the right side wall of the long leg 6 and the right side wall of the short side 7 of the single-tooth track shoe 5 to detect whether there are defects in the AB and CD sections of the single-tooth track shoe. If there are defects, it is preferred to use a feeler gauge to measure the defect size to determine whether the leg shape is qualified. When measuring the shape of the other side (i.e., the left side) of the single-tooth track shoe 5, as shown in FIG. Figure 4 As shown, the bottom of the detection groove 1 is fitted with the leg end of the single-tooth track shoe 5, and the left side wall of the bottom of the detection groove 1 and the detection groove 2 is fitted with the left side wall of the long leg 6 and the left side wall of the short side 7 of the single-tooth track shoe 5 to detect whether there are defects in the EF and JK sections of the single-tooth track shoe. If there are defects, it is preferred to measure the defect size with a feeler gauge to determine whether the leg shape is qualified.
