The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

It will be understood by those skilled in the art that in the disclosure of the specification, the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, which are merely for convenience in describing the utility model and to simplify the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus the terms are not to be construed as limiting the utility model.

Referring to fig. 1 to 5, a detection tool according to a preferred embodiment of the present invention will be described in detail below, wherein the detection tool is used for detecting a workpiece 90, and mainly detects whether the position of a mounting hole 901 on the workpiece 90, the depth of a pipe 902 on the workpiece 90 and the size of the aperture of the pipe 902 are acceptable. The position degree is a range in which the axis or the central plane of the body allows the position of the body to be changed, that is, the range in which the actual position of the axis or the central plane of the body is allowed to be changed is an index for limiting the amount of change of the actual position of the element to be measured from the ideal position. The positional degrees include positional degrees of points, positional degrees of lines, and positional degrees of faces. Only if the position degrees of all the assembly holes 901 on the workpiece 90 are ensured to meet the requirements, the qualified assembly can be completed, so that the quality of the product is ensured.

The detection tool comprises a base 10, wherein the base 10 is provided with a top 101, the base is provided with a detachable measuring pin 20 at a preset position on the top 101 of the base 10, the measuring pin 20 vertically protrudes out of the top 101 and has a preset height, and the preset position and the preset height can be adaptively set according to the actual needs in the field. For example, for the position degree detection of the assembly holes 901 on the oil pans of the transmission case, the predetermined position includes positions of the assembly holes 901 on all models of oil pans of the transmission case, and the predetermined height is a height corresponding to the assembly holes 901 on all models of oil pans. When each oil pan is detected, only the unnecessary measuring pins 20 need to be removed, the measuring pins 20 corresponding to the oil pan to be detected are left, and the oil pan to be detected is correspondingly placed on the surface of the base 10, so that the position degree of the assembling holes 901 on the oil pan can be quickly detected through the detection tool, and the oil pan cannot be well sealed on the top surface of the base 10 as long as the position degree of any assembling hole 901 is unqualified.

In addition, in order to facilitate the assembling and disassembling of the measuring pin 20 on the base 10, the base 10 is respectively provided with a limiting hole 102 for accommodating and fixing the measuring pin 20 at the predetermined position. The limiting hole 102 may be a blind hole formed in the top 101, or may be a through hole penetrating through the base 10.

As a preferred embodiment of the present invention, the predetermined positions have a plurality of predetermined positions, and the plurality of measuring pins 20 disposed at the predetermined positions have predetermined specifications, wherein the plurality of measuring pins 20 may have the same specification or different specifications, and are mainly disposed correspondingly to the assembling holes 901 on the workpiece 90 to be tested.

Preferably, in order to facilitate the placement of the workpiece 90 and the observation of the matching degree between the workpiece 90 and the base 10, the base 10 is uniformly provided with a plurality of supporting members 103 along the circumferential direction, such as supporting rods or supporting frames, so as to support the base 10, so that the base 10 has a certain height similar to human engineering.

It is further preferred that the base 10 is further symmetrically provided with at least two handles 104 along the circumferential direction, wherein the handles 104 are preferably implemented as two or four, wherein a plurality of the handles 104 are symmetrically distributed along the length direction of the base 10, or are uniformly distributed along the circumferential direction of the base 10.

In the case that the inner diameter of the pipe 902 is smaller than the outer diameter of the moving assembly 30, as a preferred embodiment of the present invention, the base 10 is further provided with a moving assembly 30, wherein the moving assembly 30 is directionally movably arranged on the base 10 along the vertical direction and has a predetermined initial position relative to the base 10. When the moving assembly 30 is located at the initial position, the moving assembly 30 at least partially protrudes downward from the base 10, so that when the moving assembly 30 is pressed down by the pipe 902 on the workpiece 90, the depth dimension of the pipe 902 can be rapidly detected according to the downward movement increment of the moving assembly 30.

Moreover, for the case that the inner diameter of the pipe 902 is larger than the outer diameter of the moving assembly 30, as another preferred embodiment of the present invention, the base 10 is further provided with a limiting assembly 40, wherein the limiting assembly 40 comprises a contoured sleeve 401, wherein the contoured sleeve 401 is fixedly disposed on the base 10, and the moving assembly 30 is directionally movably disposed in the contoured sleeve 401;

meanwhile, a position avoiding structure 4011 is arranged on the inner side of the opening of the profiling sleeve 401 close to the top 101, wherein the position avoiding structure 4011 is matched with the moving assembly 30, so that when the moving assembly 30 is located at the initial position, a detection groove 4012 can be formed between the position avoiding structure 4011 and the moving assembly 30. Whether the inner aperture size of the pipe 902 is qualified or not can be detected quickly through the detection groove 4012, and in addition, for the case that the inner aperture size of the pipe 902 is larger than the outer diameter size of the moving assembly 30, if the depth of the pipe 902 is too deep, that is, the length of the pipe 902 is larger than a standard length, the pipe 902 can only reach the bottom of the detection groove 4012, and then the pipe 902 supports the workpiece 90 by a certain height, so that a certain gap is formed between the workpiece 90 and the base 10; if the depth of the conduit 902 is too shallow, which means that the length of the conduit 902 is less than the standard length, the bottom wall of the conduit 902 will press the moving assembly 30 to move downward until the conduit 902 reaches the bottom of the detecting groove 4012, and will not move any more. Since the moving member 30 has a predetermined initial position, the distance that the moving member 30 moves downward is the length dimension of the pipe 902 shorter than that of the standard pipe 902. When the depth of the pipe 902 and the aperture size of the pipe 902 meet the requirements, the pipe 902 can be smoothly embedded into the detection groove 4012 and abut against the bottom of the detection groove 4012, and the moving component 30 cannot be moved.

Therefore, for any pipeline with the inner aperture size within the spatial range of the detection groove 4012, the detection tool can quickly detect the depth size of the pipeline 902, or simultaneously detect whether the depth size and the inner aperture size of the pipeline 902 are qualified.

Preferably, the limiting assembly 40 further comprises a limiting sleeve 402, wherein the limiting sleeve 402 is disposed at the bottom of the profiling sleeve 401 and has a limiting groove 4021 communicating with the profiling sleeve 401, wherein the inner diameter of the limiting groove 4021 is larger than the inner diameter of the profiling sleeve 401, so as to provide a space for avoiding downward movement of the moving assembly 30. The groove bottom of the limiting groove 4021 is provided with a through hole 4022 for the moving assembly 30 to pass through, so as to protrude downwards from the bottom of the limiting assembly 40.

Meanwhile, the moving assembly 30 includes a moving member 301, a measuring member 302 and an elastic member 303, wherein the moving member 301 is matched with the profiling sleeve 401, and a blocking portion 3011 matched with the limiting groove 4021 is arranged at the bottom of the moving member 301. The measuring member 302 is fitted into the through hole 4022 and is connected to the bottom of the moving member 301. The elastic element 303 is connected in compression between the moving element 401 and the groove bottom of the limiting groove 4021, so as to be able to support the moving element 301 in a rebounding manner and form the initial position when the stopping part 3011 abuts against the bottom of the profiling sleeve 401.

In short, under the continuous rebound force of the elastic element 303 tending to rebound, the blocking portion 3011 is held at the bottom of the profiling sleeve 401, so that the moving element 301 has the stable initial position, and the measuring element 302 is kept at a certain initial protruding length protruding out of the limiting assembly 40. When the length of the pipe 902 on the workpiece 90 to be measured is too short, the pipe 902 overcomes the resilience of the elastic member 303, so as to compress the moving member 301 downwards through the bottom wall thereof; when the length of the pipe 902 on the workpiece 90 to be detected is too long, the pipe 902 is prevented from continuously descending when the pipe 902 abuts against the bottom of the detection groove 401, so that a certain gap is kept between the workpiece 90 to be detected and the base 10.

Preferably, the moving member 301 is implemented as a knock pin. The measuring member 302 is detachably mounted to the bottom of the moving member 301.

Further preferably, in order to facilitate the installation and fixation of the limiting assembly 40 on the base 10, the limiting assembly 40 further includes a first mounting plate 403 and a second mounting plate 404, wherein the first mounting plate 403 and the second mounting plate 404 are vertically disposed on the outer walls of the profiling sleeve 401 and the limiting sleeve 402 respectively, so as to be capable of detachably connecting the base 10 respectively and make the profiling sleeve 401 and the limiting sleeve 402 more stable.

Further preferably, the top of the base 10 is provided with a receiving groove 105 matched with the first mounting plate 403, so as to provide a limit for the first mounting plate 403, thereby facilitating the quick installation of the first mounting plate 403, and at the same time, making the first mounting plate 403 more stable, and in addition, making the first mounting plate 403 not protrude from the top of the base 10, so as to affect the detection of the position degree of the measuring pin 20 on the assembling hole 901.

According to an embodiment of the present invention, the elastic member 303 is implemented as a spring. The elastic member 303 is fitted over the measuring member 302.

It should be noted that the terms "first and second" in the present invention are used for descriptive purposes only, do not denote any order, are not to be construed as indicating or implying any relative importance, and are to be interpreted as names.
