All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The core of the utility model is to provide a gauge which can realize convenient and rapid measurement of the relative positions of all hole sites on a product.

Referring to fig. 1-6, an embodiment of the present utility model provides a testing tool, including a first testing element 1 and a second testing element 2, where the first testing element 1 is provided with a first groove 11, the first groove 11 is used for matching with a first portion of a workpiece 4, a first protruding portion 12 is provided in the first groove 11, and the first protruding portion 12 is used for being inserted into a first hole 41 of the first portion of the workpiece 4; the second inspection piece 2 is used for being matched with the first inspection piece 1, the second inspection piece 2 is provided with a second groove 21, the second groove 21 is used for being matched with a second part of the workpiece 4, a second protruding part 22 is arranged in the second groove 21, and the second protruding part 22 is used for being inserted into a second hole 42 of the second part.

Referring to fig. 7-10, when the inspection tool is used to inspect a workpiece 4, the workpiece 4 is placed into the first recess 11 of the first inspection piece 1 such that the first boss 12 can pass through the first hole 41 of the first portion of the workpiece 4, and then the second inspection piece 2 is positioned in cooperation with the first inspection piece 1 such that the second recess 21 of the second inspection piece 2 is in cooperation with the second portion of the workpiece 4 and such that the second boss 22 can pass through the second hole 42 of the second portion of the workpiece 4. In this process, if the workpiece 4 can be smoothly placed into the first groove 11 of the first inspection piece 1, and the first protruding portion 12 can smoothly pass through the first hole 41; further, the second inspection piece 2 can be successfully matched and positioned with the first inspection part, and the second protruding part 22 can successfully pass through the second hole 42, so that the relative positions of the holes on the workpiece 4 are qualified, and the workpiece 4 is judged to be qualified; conversely, if the first protruding portion 12 cannot pass through the first hole 41 when the workpiece 4 is placed in the first groove 11, or if the second protruding portion 22 cannot pass through the second hole 42 when the second test piece 2 is positioned in cooperation with the first test piece 1, the relative positions of the holes on the workpiece 4 are determined to be failed, and the workpiece 4 is determined to be failed.

Therefore, the embodiment of the utility model detects whether the workpiece 4 is qualified or not by utilizing the structural characteristics of the first checking piece 1 and the second checking piece 2 and the matched positioning of the first checking piece 1 and the second checking piece 2, and has simple and convenient operation, and can quickly determine whether the workpiece 4 is qualified or not, so that the relative position between all hole sites on the workpiece 4 can be conveniently and quickly measured.

In this embodiment, the specific shape, number, distribution, etc. of the first protruding portion 12 and the second protruding portion 22 are not particularly limited, and only the first protruding portion 12 and the second protruding portion 22 may pass through the first hole 41 and the second hole 42 of the workpiece 4, respectively, so as to perform the function of detecting the positions of the first hole 41 and the second hole 42. In some embodiments, the shape, number, and distribution of the first protrusions 12 are the same as the shape, number, and distribution of the first holes 41 of the workpiece 4; the shape, number and distribution of the second protrusions 22 are the same as the shape, number and distribution of the second holes 42 of the work piece 4. Of course, in other embodiments, the shape of the first protruding portion 12 may be different from the shape of the first hole 41, and the shape of the second protruding portion 22 may be different from the shape of the second hole 42, so long as the first protruding portion 12 can pass through the first hole 41 and perform a detection function on the first hole 41; similarly, the second protruding portion 22 can pass through the second hole 42, and thus, the second hole 42 can be detected. In addition, the specific shape of each of the first hole 41 and the second hole 42 of the workpiece 4 is not limited in the embodiment of the present utility model, for example, the first hole 41 and the second hole 42 may be holes with regular shapes or shaped holes, respectively; the first and second holes 41 and 42, respectively, may be circumferentially closed holes or non-circumferentially closed holes. The number of the first holes 41 and the second holes 42 may be one or at least two, respectively.

In addition, as shown in fig. 1, 4 and 10, in some embodiments, the gauge further includes a third inspection piece 3, the third inspection piece 3 being slidably disposed in the first inspection piece 1 and extendable into the first recess 11, the third inspection piece 3 being configured to be inserted into a third hole 43 of the workpiece 4.

That is, in the present embodiment, the third inspecting member 3 is used to detect the third hole 43 of the workpiece 4, when the second inspecting member 2 and the first inspecting member 1 are cooperatively positioned during detection, the third inspecting member 3 is slid so that the third inspecting member 3 extends into the first groove 11 and passes through the third hole 43 of the workpiece 4, and if the third inspecting member 3 can pass through the third hole 43 smoothly, the workpiece 4 is determined to be qualified; if the third inspection piece 3 cannot pass through the third hole 43, the workpiece 4 is judged to be unqualified, the operation is simple and convenient, and whether the position of the third hole 43 is correct or not can be quickly judged.

It should be noted that, in the present embodiment, the specific structure of the third test element 3 is not limited, and it is understood that the cross-sectional profile of the third test element 3 is the same as the shape of the third holes 43 of the workpiece 4, and the number of the third test elements 3 is the same as the number of the third holes 43. In some embodiments, the third inspection piece 3 is a rod-like piece.

Further, as shown in fig. 1 and 2, in order to enhance the versatility of the inspection tool, in some embodiments, two opposite sidewalls of the first inspection piece 1 corresponding to the first groove 11 are respectively provided with a through hole 13, and the through holes 13 are used for the third inspection piece 3 to pass through. That is, when the third hole 43 of the workpiece 4 faces any one of two opposite groove walls of the first groove 11, the third inspection piece 3 can pass through the through hole 13 and extend into the first groove 11, so that the third inspection piece 3 inspects the third hole 43, thereby improving the universality of the inspection tool and facilitating the inspection of the workpiece 4.

In addition, considering the ease of mating positioning of the first and second test pieces 1, 2, please refer to fig. 1-3, in some embodiments, one of the first and second test pieces 1, 2 is provided with a positioning post 14, and the other is provided with a positioning hole 23 for mating positioning with the positioning post 14. That is, when the second test element 2 is positioned in cooperation with the first test element 1, the positioning column 14 is inserted into the positioning hole 23, and the cooperation positioning of the first test element 1 and the second test element 2 is realized by the cooperation limitation of the positioning column 14 and the positioning hole 23.

It should be noted that, in the present embodiment, the specific number and distribution of the positioning posts 14 and the positioning holes 23 are not limited, for example, in some embodiments, the number of the positioning posts 14 and the positioning holes 23 is four, and the positioning posts 14 and the positioning holes 23 are arranged in a one-to-one correspondence.

Further, as shown in fig. 9 and 10, in some embodiments, after the first inspection piece 1 and the second inspection piece 2 are cooperatively positioned, the end surfaces of the first groove 11 and the second groove 21 are bonded to form a cavity that circumferentially envelopes the workpiece 4. That is, after the first inspection piece 1 and the second inspection piece 2 are cooperatively positioned, the first groove 11 and the second groove 21 are combined to form a circumferentially closed space, so that holes with any angle on the circumference of the workpiece 4 can be detected easily, and the detection is more comprehensive.

In addition, referring to fig. 2, 5-7 and 9, in some embodiments, the first boss 12 includes a through post 121, the through post 121 being configured to pass out of the fourth aperture 44 of the second portion. That is, the through-column 121 penetrates the work 4 after passing through the first hole 41 of the first portion of the work 4, and passes out of the fourth hole 44 of the second portion of the work 4. If the through-hole 121 can pass through the fourth hole 44 smoothly, the work 4 is judged to be acceptable, and if the through-hole 121 passes through the first hole 41 and passes through the work 4, and then cannot pass through the fourth hole 44, the work 4 is judged to be unacceptable. This further promotes the versatility of the gauge, making the positions of the holes that the gauge can detect more diverse.

Further, since the through-post 121 penetrates the workpiece 4 and then passes through the fourth hole 44, in order to avoid interference between the through-post 121 and the second groove 21, as shown in fig. 3, in some embodiments, a relief hole 24 for avoiding the through-post 121 is provided in the second groove 21. That is, in the present embodiment, the through-hole 24 is provided to avoid the through-hole 121, so that the through-hole 121 is prevented from interfering with the second groove 21.

In addition, for detecting the end of the workpiece 4, referring to fig. 2, 3 and 10, in some embodiments, a first limiting portion 15 for limiting the end of the workpiece 4 is disposed in the first groove 11; a second limiting part 25 for limiting the end of the workpiece 4 is arranged in the second groove 21. That is, when the workpiece 4 is placed in the first groove 11 during the inspection, one end of the workpiece 4 is brought into contact with the first limiting portion 15 to ensure that the first hole 41 of the first portion of the workpiece 4 has a proper position to the end of the workpiece 4; when the second detecting member is cooperatively positioned with the first detecting member and the second protruding portion 22 passes through the second hole 42, the second limiting portion 25 is brought into contact with the end portion of the workpiece 4, so as to ensure that the second hole 42 of the second portion of the workpiece 4 is properly positioned to the end portion of the workpiece 4. This ensures that the distance between the first hole 41 and the second hole 42, respectively, and the end of the workpiece 4 is dimensioned to be acceptable.

Further, in some embodiments, the first and second limiting portions 15 and 25 are each located at an end remote from the through-post 121. It can be understood that the through-column 121 passes through the first hole 41 and the workpiece 4 and then passes out of the fourth hole 44, so that the position of the workpiece 4 near one end of the through-column 121 can be determined by using the through-column 121, and the first limiting portion 15 and the second limiting portion 25 are both disposed at one end far from the through-column 121, which is beneficial to limiting the other end of the workpiece 4.

In addition, in order to enable the gauge to accommodate workpieces 4 of different shapes, as shown in fig. 2 and 5, in some embodiments, the workpiece 4 has a first planar surface 45, and the first groove 11 or the second groove 21 is provided with a second planar surface 111 for abutting contact with the first planar surface 45. That is, the present embodiment adapts the first flat surface 45 of the work 4 by providing the second flat surface 111 in the first groove 11 or the second groove 21 to ensure accuracy of positioning the work 4, thereby ensuring accuracy of detection. This applies to a workpiece 4 having a flat surface, for example, a workpiece 4 having a D-shaped cross section, which improves versatility of the gauge.

It should also be noted that in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

In this specification, each embodiment is described in a progressive manner, and each embodiment is mainly described by a difference from other embodiments, and identical and similar parts between the embodiments are referred to each other.
