Description

Technical Field

[0001] The utility model relates to the technical field of inspection tools, in particular to an inspection tool for detecting a rotating target port. Background Art

[0002] The port of the rotating target is as follows Figure 5 As shown, there is a tapered surface 1 at its end, which is equivalent to the side of the frustum. The generatrix of the frustum is aligned with the lower base ( Figure 5 The bottom surface on the right side of the center of the target forms a 60° angle with the cone. The diameter of the lower base of the cone is 127.8±0.2 mm. In the prior art, when inspecting the tapered surface 1 after machining, a universal angle ruler is generally used to measure the 60° angle, and then a vernier caliper is used to measure the diameter of the lower base of the cone. Because the widths of the tapered surface 1 and the target end face are relatively narrow, it is difficult to ensure that they are always completely aligned with the corresponding edges of the universal angle ruler during the measurement process. Therefore, measuring the angle is difficult and time-consuming. The diameter of the lower base of the cone cannot be clamped by the inner and outer measuring jaws of the vernier caliper, so measuring it is also difficult and time-consuming. The present application provides a testing tool that can determine whether the tapered surface 1 is qualified without measuring it (here referring to obtaining an accurate value). Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a testing tool for detecting a rotating target port in response to the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a gauge for detecting a rotating target port, comprising a gauge 1 and a gauge 2, wherein both the gauge 1 and the gauge 2 include a baffle, the cross-section of the baffle is semicircular, the outer diameter of the baffle is larger than the diameter of the lower bottom surface of the tapered surface, one side of the baffle on the gauge 1 is provided with a first taper detection portion coaxial with the baffle, and one side of the two is flush, the angle between the generatrix of the first taper detection portion and the lower bottom surface is a standard angle, and the diameter of the lower bottom surface of the first taper detection portion is the upper limit of the allowable value, and one side of the baffle on the gauge 2 is provided with a second taper detection portion coaxial with the baffle, and one side of the two is flush, the angle between the generatrix of the second taper detection portion and the lower bottom surface is a standard angle, and the diameter of the lower bottom surface of the second taper detection portion is the lower limit of the allowable value.

[0005] To further optimize the technical solution, a handle is provided on a side of the baffle away from the first taper detection portion or the second taper detection portion.

[0006] To further optimize this technical solution, the handle is cylindrical.

[0007] To further optimize the technical solution, an inner diameter detection portion is provided on the side of the first taper detection portion and the second taper detection portion away from the baffle 2 .

[0008] To further optimize the technical solution, a rounded corner is provided on a side of the inner diameter detection portion away from the baffle.

[0009] Compared with the prior art, the present invention has the following advantages: the diameter of the lower bottom surface of the first taper detection part on the first inspection tool is the upper limit of the allowable value, and the diameter of the lower bottom surface of the second taper detection part on the second inspection tool is the lower limit of the allowable value. By observing whether the two can be fully inserted into the target material port, it can be judged whether the taper surface is qualified. The inspection is easy to operate and relatively quick.

[0016] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0017] Specific implementation method: Figure 1-4As shown, a test fixture for detecting a rotating target port includes a test fixture 1 and a test fixture 2, both of which include a baffle 2, the cross section of the baffle 2 (the cross section here refers to the cross section perpendicular to the axis, the same below) is semicircular, the outer diameter of the baffle 2 is larger than the lower bottom surface diameter of the tapered surface 1, and the outer diameter of the baffle 2 is preferably equal to the outer diameter of the port, and a first tapered detection portion 3 coaxial with the baffle 2 on one side of the test fixture is provided, and one side of the two is flush, that is, the cross section of the first tapered detection portion 3 is also semicircular, and the angle between the busbar of the first tapered detection portion 3 and the lower bottom surface is a standard angle, for detection Figure 5 The standard angle of the target port shown in the figure is 60°. The diameter of the lower bottom surface of the first taper detection part 3 (i.e., the bottom surface close to the baffle 2. The diameter of the lower bottom surface is greater than the diameter of the upper bottom surface) is the upper limit of the allowable value. For example, the allowable value is 127.8±0.2 mm (the same below). The diameter of the lower bottom surface of the first taper detection part 3 is 128 mm. The baffle 2 on the second inspection tool is provided with a coaxial second taper detection part 6 on one side and the two sides are flush. The angle between the busbar of the second taper detection part 6 and the lower bottom surface is the standard angle. Figure 5 The standard angle of the target port shown in FIG is 60°, and the diameter of the bottom surface of the second taper detection portion 6 is the lower limit of the allowable value, so the diameter of the bottom surface of the second taper detection portion 6 is 127.6 mm. Figure 1 and Figure 3 It can be seen that the first taper detection part 3 and the second taper detection part 6 are both in the shape of a semi-cone (the cone is divided into two parts by a plane passing through the axis of the cone, and either of the two parts is in the shape of a semi-cone). Figure 4As shown, first insert the inspection tool 1 into the port. If the inspection tool 1 can be fully inserted, that is, there is no gap between the baffle 2 and the end face of the target port, then it means that the bottom diameter of the tapered surface 1 is greater than or equal to 128 mm, equal to or exceeds the upper limit of the allowable value, and it is unqualified (it is exactly 128 mm and is judged to be unqualified). If the inspection tool 1 cannot be fully inserted (at this time, the lower bottom diameter of the tapered surface 1 is less than 128 mm, or it may be that the lower bottom diameter of the tapered surface 1 is greater than 128 mm and the angle between the generatrix of the tapered surface 1 and the lower bottom surface is too small), that is, there is a gap between the baffle 2 and the end face of the target port, then use the inspection tool 2 to insert into the port. If the inspection tool 2 cannot be fully inserted, it is unqualified (at this time, the lower bottom diameter of the tapered surface 1 is less than 127.6 mm, or it may be that the angle between the generatrix of the tapered surface 1 and the lower bottom surface is too small. If any one of the two is unqualified, the tapered surface 1 is unqualified, and there is no need to specifically analyze which one is unqualified). If it can be fully inserted (at this time, the diameter of the lower base of the tapered surface 1 is greater than or equal to 127.6 mm and is considered to be less than 128 mm), the diameter of the lower base of the tapered surface 1 is temporarily considered qualified (because it also includes the situation that the diameter of the lower base of the tapered surface 1 is greater than 128 mm and the angle between the generatrix of the tapered surface 1 and the lower base is too small, whether the angle is qualified will be tested later), then observe whether the gap between the generatrix of the end face of the second taper detection part 6 and the tapered surface 1 is parallel, if not parallel, the tapered surface 1 is unqualified (including two situations, the first, the diameter of the lower base of the tapered surface 1 is qualified and the angle between the generatrix of the tapered surface 1 and the lower base is unqualified, the second, that is, the diameter of the lower base of the tapered surface 1 is greater than 128 mm and the angle between the generatrix of the tapered surface 1 and the lower base is too small), if it is parallel, it is qualified (the angle between the generatrix of the tapered surface 1 and the lower base is qualified, and it means that the diameter of the lower base of the tapered surface 1 is qualified). The conditions for judging that the tapered surface 1 is qualified are: the first inspection tool cannot be fully inserted into the target material port, while the second inspection tool can be fully inserted into the target material port, and the generatrix of the end face of the second taper detection part 6 is parallel to the gap between the tapered surface 1. The inspection using the inspection tool of the present application is relatively quick and easy to operate.

[0018] Furthermore, a handle 5 is provided on the side of the baffle 2 away from the first taper detection portion 3 or the second taper detection portion 6 to facilitate use by detection personnel.

[0019] Furthermore, the handle 5 is cylindrical, which is easy to hold and does not hurt the hand.

[0020] Furthermore, the first taper detection portion 3 and the second taper detection portion 6 are provided with an inner diameter detection portion 4 on the side away from the baffle 2. The inner diameter detection portion 4 is semi-cylindrical and coaxial with the baffle 2. The diameter of the inner diameter detection portion 4 is 125 mm. The inner diameter detection portion 4 is used to detect the inner diameter of the target port. The inner diameter of the target port is Figure 5The inner diameter of the left side of the left end of the middle tapered surface 1 is equal to or slightly larger than 125 mm. When the inner diameter detection part 4 cannot be inserted Figure 5 If the left side of the left end of the tapered surface 1 is smaller than 125 mm, the inner diameter of the port is unqualified. Figure 5 When inspecting the left side of the left end of the middle tapered surface 1, observe whether there is an obvious gap between the busbar of the end face of the inner diameter detection part 4 and the inner wall of the target port. If there is no obvious gap, it is qualified. If there is an obvious gap, it is unqualified. Since the size requirement is not very strict, this method can be used for detection.

[0021] Furthermore, a rounded corner 41 is provided on a side of the inner diameter detection portion 4 away from the baffle 2 to facilitate insertion of the inner diameter detection portion 4 into the target port.

[0022] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
