Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to a detection tooling used for measuring the height of cylindrical parts. Background Art

[0002] In the traditional manufacturing industry, it is a common but challenging task to accurately measure the height of cylindrical parts to determine whether their height meets the tolerance range of the process. Height gauges and calipers have long been widely used in dimensional inspection as mainstream measuring tools. Although they meet basic measurement needs to a certain extent, the limitations of these traditional measurement methods are becoming increasingly prominent as the manufacturing industry continues to increase its requirements for product quality and production efficiency.

[0003] The measurement accuracy of height gauges and calipers is often limited by the mechanical structure and wear of the instruments themselves. After long-term use, slight wear will cause reading deviations, affecting the accuracy of the measurement results. In addition, the operation of these tools depends on the proficiency of the operator. Human factors such as reading errors and uneven force application will also have a significant impact on the final measurement data. Especially when a large number of cylindrical parts need to be fully inspected, manual operation is not only time-consuming and laborious, but also difficult to ensure the consistency and reliability of each measurement, which greatly reduces production efficiency and product quality control.

[0004] It can be seen that the existing detection methods have problems of low efficiency and low measurement accuracy when facing high-precision, large-volume cylindrical parts size detection. Utility Model Content

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problems of low efficiency and low measurement accuracy in the prior art when detecting the dimensions of high-precision and large-volume cylindrical parts, the utility model provides a detection tool for measuring the height of cylindrical parts.

[0032] like Figure 1-3 As shown, an embodiment of the utility model provides a detection tool for measuring the height of a cylindrical part 5, including a support wall 1, a limiting wall 2 and a connecting wall 3, wherein the support wall 1 and the limiting wall 2 are arranged opposite to each other, and the connecting wall 3 is connected between the same side of the support wall 1 and the limiting wall 2.

[0033] Corresponding to Figure 3 In the figure, the direction of the x-axis is the width direction of the supporting wall 1 and the limiting wall 2, the direction of the y-axis is the length direction of the supporting wall 1 and the supporting wall 2, and the direction of the z-axis is the height direction of the supporting wall 1 and the supporting wall 2. In this embodiment, the connecting wall 3 is connected between the same side of the supporting wall 1 and the limiting wall 2 in the width direction, and the connecting wall 3 is extended along the direction of the y-axis.

[0034] The support wall 1 has a first plane 11 arranged toward the limiting wall 2, and a limiting groove 21 opening downward is provided on one side of the limiting wall 2 facing the support wall 1, and a step surface 211 is formed on the bottom wall of the limiting groove 21, and the step surface 211 includes a second plane 2111 and a third plane 2112 spaced apart in a direction perpendicular to the first plane 11, and the second plane 2111 and the third plane 2112 are parallel to the first plane 11, and the detection tooling includes a channel 41 for the cylindrical part 5 to enter between the first plane 11 and the second plane 2111 and between the first plane 11 and the third plane 2112.

[0035] It should be noted that the positive projection of the groove side wall of the limiting groove 21 on the first plane 11 is located within the edges of the first plane. In this way, the top of the cylindrical part 5 is limited by the groove side wall of the limiting groove 21, thereby correspondingly limiting the movement of the bottom end of the cylindrical part 5, preventing the cylindrical part 5 from sliding out of the first plane.

[0036] refer to Figure 2 As shown, it can be understood that in the direction perpendicular to the first plane 11, the second plane 2111 is closer to the first plane 11 than the third plane 2112.

[0037] The height between the first plane 11 and the third plane 2112 is h1, which is the sum of the standard height of the cylindrical part 5 and the tolerance value. Correspondingly, the height between the first plane 11 and the second plane 2111 is h2, which is the difference between the standard height of the cylindrical part 5 and the tolerance value. When the cylindrical part 5 can be inserted between the first plane 11 and the third plane 2112, and cannot be inserted between the first plane 11 and the second plane 2111, it indicates that the height of the cylindrical part 5 is within the tolerance range.

[0038] It can be seen that the utility model provides a limiting groove 21 on the surface of the limiting wall 2 facing the supporting wall 1, and sets a stepped surface 211 on the bottom of the limiting groove 21. In this way, on the one hand, the second plane 2111 and the third plane 2112 of the stepped surface are matched with the first plane 11 respectively, so as to quickly judge whether the height of the cylindrical part 5 meets the process requirements; on the other hand, the limiting groove 21 prevents the cylindrical part 5 from sliding out of the first plane 11 on the horizontal plane.

[0039] Optionally, the side wall of the limiting groove 21 is arranged perpendicular to the first plane 11. Such an arrangement helps the side wall 212 to define the cylindrical part 5.

[0040] Preferably, the limiting groove 21 has a side wall 212 arranged relative to the channel 41, and the inner side of the side wall 212 is provided with a concave arc surface 2121 for matching with the side wall of the cylindrical part 5. The concave arc surface 2121 can be well fitted with the side wall of the cylindrical part 5, so that the position of the cylindrical part 5 can be relatively fixed with the limiting wall 2 to prevent it from shaking.

[0041] Furthermore, the support wall 1 and the connecting wall 3 are formed in one piece, so as to ensure the stability of the combination of the two.

[0042] In this embodiment, the channel 41 is formed on the side wall of the limiting groove 21. Such a configuration can fully exert the limiting function of the side wall.

[0043] Next reference Figure 4 , Figure 4 Another embodiment of the present invention is provided. In this embodiment, the limiting groove is configured to open downward and toward at least one side. The opening of the limiting groove toward at least one side forms the channel 42.

[0044] Such a configuration is more conducive to inserting the cylindrical part 5 between the first plane 11 and the second plane 2111 , or between the first plane 11 and the third plane 2112 .

[0045] In summary, the embodiments of the present invention achieve the following technical effects:

[0046] The utility model provides a limiting groove 21 on one surface of the limiting wall 2 facing the supporting wall 1, and arranges a stepped surface 211 on the bottom of the limiting groove 21. Thus, on the one hand, the second plane 2111 and the third plane 2112 of the stepped surface respectively cooperate with the first plane 11, so as to quickly judge whether the height of the cylindrical part 5 meets the process requirements; on the other hand, the limiting groove 21 prevents the cylindrical part 5 from sliding out of the first plane 11 on the horizontal plane.
