In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 6, in one embodiment, an on/off detection tool is provided, which includes a base 100, an adjustment assembly 200, a second detection portion 300, and a pitch check element (not shown). Specifically, the base 100 includes a mounting portion 110 and a first detecting portion 120 that are oppositely disposed at an interval, the mounting portion 110 is provided with a mounting through hole 1111; the adjusting assembly 200 is disposed through the mounting through hole 1111, and the adjusting assembly 200 can move back and forth in a direction (as shown in a direction of fig. 1 to 6 a) toward or away from the first detecting portion 120 along the axial direction of the mounting through hole 1111; the second detecting part 300 is connected with one end of the adjusting assembly 200 close to the first detecting part 120, and the second detecting part 300 and the first detecting part 120 are oppositely arranged at intervals to form a first detecting gap 410; the pitch check element is used to check the first detection gap 410.

When the on-off detection tool of the above embodiment needs to perform on-off detection, the adjusting assembly 200 is adjusted, and the adjusting assembly 200 is utilized to drive the second detecting portion 300 to move towards the direction close to or away from the first detecting portion 120 along the axial direction of the mounting through hole 1111 until the distance between the second detecting portion 300 and the first detecting portion 120 meets the preset distance requirement to form the first detecting gap 410. And then, the first detection interval is checked by using an interval checking element, so that whether the actually adjusted first detection interval 410 meets the requirement of the preset interval is verified, and the accuracy of subsequent on-off detection is ensured. If the distance checking element detects that the first detection gap 410 meets the preset distance requirement, during subsequent pass-stop detection, only the part 1000 to be detected is inserted or sleeved into the first detection gap 410, if the part 1000 to be detected can be inserted or sleeved into the first detection gap 410, the size of the part 1000 can be judged to be qualified, and if the part 1000 to be detected cannot be inserted or sleeved into the first detection gap 410, the size of the part 1000 can be judged to be unqualified, so that the method is simple and convenient, and the detection efficiency is improved.

The preset spacing may be flexibly designed or adjusted according to the detection requirements of different components 1000. For example,

wherein, the installation part 110 can be massive, platform-shaped or columnar, and the installation part 110 can provide installation part 110 position and supporting part for the adjusting component 200, and the adjusting component 200 of being convenient for drives the second detection part 300 to move to and fro along the axial direction of the installation through hole 1111 towards the direction of being close to or being far away from the first detection part 120.

The distance check element may be a height gauge or other existing element capable of checking the distance.

Wherein, adjusting part 200 drives second detection portion 300 and is close to or keeps away from first detection portion 120 direction reciprocating motion along the axial orientation of installation through-hole 1111, can realize through flexible mode, also can realize through the pivoted mode, also can realize through the mode of pulling out, only need satisfy make second detection portion 300 can carry out straight reciprocating motion along the axial of installation through-hole 1111 can.

As shown in fig. 7, optionally, the mounting portion 110 includes a mounting block 111, the mounting block 111 is provided with a mounting through hole 1111 and a limiting hole 1112 communicated with the mounting through hole 1111, and an inner side wall of the mounting through hole 1111 is provided with an internal thread. As shown in fig. 1 to 6, the adjusting assembly 200 includes an adjusting nut 210, a limiting member 220, and an adjusting screw 230 having a limiting groove 231 on an outer side wall thereof. The adjusting screw 230 is in threaded fit with the internal thread, and the adjusting nut 210 is sleeved on the outer side wall of the adjusting screw 230 and is in threaded fit with the adjusting screw 230. The limiting member 220 is inserted into the limiting hole 1112, and one end of the limiting member 220 is in limiting fit with the limiting groove 231. So, when rotating adjusting nut 210, utilize adjusting nut 210 and adjusting screw 230's screw-thread fit to combine locating part 220 to adjusting screw 230's limiting displacement, thereby make adjusting screw 230 along the axial reciprocating motion of installation through-hole 1111, and then drive the axial reciprocating motion of second detection portion 300 along installation through-hole 1111, thereby adjust first detection clearance 410, satisfy the requirement of predetermineeing the interval until first detection clearance 410. In addition, the adjusting screw 230 reciprocates along the axial direction of the mounting through hole 1111 by the thread matching of the adjusting nut 210 and the adjusting screw 230, so that the adjusting screw 230 can realize the small displacement of a single thread pitch, and the first detection gap 410 can be finely adjusted, so that the first detection gap 410 accurately meets the requirement of the preset distance.

As shown in fig. 1 and 7, the mounting block 111 is further provided with a mounting groove 1113 correspondingly communicated with the mounting through hole 1111, and the adjusting nut 210 is sleeved on the outer side wall of the adjusting screw 230 and is disposed in the mounting groove 1113. So, set up adjusting nut 210 in mounting groove 1113, utilize two relative lateral walls of mounting groove 1113 to carry out bearing and spacing to adjusting nut 210, be convenient for adjust adjusting screw 230.

Specifically, the mounting groove 1113 may be formed in the middle of the mounting block 111, so that the mounting groove 1113 is correspondingly communicated with the mounting through hole 1111, the adjusting nut 210 can be mounted in the mounting groove 1113, and the adjusting nut 210 can be prevented from being lost.

In order to facilitate the rotation of the adjusting nut 210, the roughness of the outer side wall of the adjusting nut 210 may be increased, or anti-slip elements such as anti-slip sleeves may be sleeved on the outer side wall of the adjusting nut 210.

Both the first detecting portion 120 and the second detecting portion 300 may be in a table shape, a block shape, or a strip shape, and only the component 1000 needs to be subjected to the pass/stop detection.

As shown in fig. 1 and 3 to 6, in one embodiment, the second detecting portion 300 includes a connecting member 310 and a first detecting head 320, and the connecting member 310 is used for connecting the adjusting assembly 200 and the first detecting head 320. Specifically, the connection member 310 is connected to an end of the adjustment screw 230 near the first detection part 120. The first detecting part 120 includes a base 121 and a second detecting head 122 connected to each other. Wherein, the base 121 and the connecting member 310 are oppositely disposed at an interval to form a first detecting gap 410. As shown in fig. 2, when the thickness, length, width, or other dimensions of the component 1000 need to be checked, after the first detection gap 410 is checked by using the distance checking element, it is only necessary to determine whether the component 1000 to be detected can be plugged into the first detection gap 410, so as to determine whether the component 1000 is qualified. In addition, the first detection head 320 and the second detection head 122 both protrude out of the first detection gap 410, and the first detection head 320 and the second detection head 122 are oppositely arranged at an interval to form a second detection gap 420, and the distance checking element is used for checking the second detection gap 420. Thus, when the outer diameter (as shown in fig. 3), the inner diameter (as shown in fig. 4) or the hole (as shown in fig. 5) of the component 1000 needs to be detected, only the adjusting assembly 200 needs to be adjusted, so as to drive the connecting member 310 and the first detecting head 320 to move until the distance between the first detecting head 320 and the second detecting head 122 meets the preset distance requirement, and a second detecting gap 420 is formed. And then, the second detection interval is checked by using the interval checking element, so that whether the actually adjusted second detection interval 420 meets the requirement of the preset interval is verified, and the accuracy of subsequent on-off detection is ensured. If the distance checking element detects that the second detection gap 420 meets the preset distance requirement, during subsequent pass-stop detection, only the part 1000 to be detected is inserted or sleeved into the second detection gap 420, if the part 1000 to be detected can be inserted or sleeved into the second detection gap 420, the inner diameter or the outer diameter of the part 1000 can be judged to be qualified, and if the part 1000 to be detected cannot be inserted or sleeved into the second detection gap 420, the outer diameter or the inner diameter of the part 1000 can be judged to be unqualified, so that the method is simple and convenient, and the detection efficiency is improved. In addition, since the first detection head 320 and the second detection head 122 both protrude the first detection gap 410 to form the second detection gap 420, that is, the first detection head 320 protrudes the connection member 310, and the second detection head 122 protrudes the base 121, so that the tubular, cylindrical or barrel-shaped component 1000 can be conveniently inserted or sleeved into the second detection gap 420 for detection, and the detection efficiency is high.

As shown in fig. 2, of course, in the actual testing process, when only the thickness, length or width of the component 1000 needs to be tested, only the connecting member 310 and the base 121 may be used to form the first testing gap 410. As shown in fig. 6, the thickness, length, or width of the component 1000 may be detected by the second detection gap 420 formed by the first detection head 320 and the second detection head 122.

The connecting member 310 may be a block, a strip, or the like. The base 121 may have a table-like or column-like structure.

As shown in fig. 9, optionally, the first detection head 320 and the second detection head 122 are both provided with a detection arc surface 321 for detecting the inner diameter. In this way, the two spaced detection arc surfaces 321 are in line contact with the inner side wall of the component 1000, so that whether the inner diameter of the component 1000 is qualified or not can be reliably detected. Specifically, a detection arc 321 may be disposed on a side of the first detection head 320 facing away from the second detection head 122, and the detection arc 321 may be disposed on a side of the second detection head 122 facing away from the first detection head 320.

As shown in fig. 9, optionally, the first detection head 320 and the second detection head 122 are both provided with a detection plane 322 for detecting the outer diameter. In this way, the two spaced detection planes 322 are in contact with the outer wall of the component 1000, and it is possible to reliably detect whether the outer diameter of the component 1000 is acceptable. Specifically, a detection plane 322 may be disposed on a side of first detection head 320 adjacent to second detection head 122, and detection plane 322 may be disposed on a side of second detection head 122 adjacent to first detection head 320.

As shown in fig. 9, optionally, a guide 323 is disposed at both an end of the first detecting head 320 away from the connecting member 310 and an end of the second detecting head 122 away from the base 121. Therefore, the guiding part 323 is used for facilitating the insertion or the sheathing of the part 1000 to be detected into the second detection gap 420, avoiding the occurrence of interference and ensuring the accuracy of the detection result. Wherein, the leading-in part can be a guide inclined plane or a guide arc surface.

In order to ensure that the first detecting head 320 and the connecting member 310 are accurately and reliably assembled and connected, it is ensured that the second detecting gap 420 can detect the outer diameter or the inner diameter of the component 1000. As shown in fig. 10 and 11, the connecting member 310 may be provided with a first connecting hole 311 and a first positioning groove 312, which are spaced apart from each other.

Therefore, the first positioning protrusion 3242 is inserted into the first positioning groove 312, so that the second connection hole 3241 is correspondingly communicated with the first connection hole 311, and the first fastening member 330 is inserted into the second connection hole 3241 and the first connection hole 311, so that the first detection head 320 and the connection member 310 are accurately and reliably assembled and connected.

Wherein, in order to guarantee that second detection head 122 and base 121 realize accurate, reliable assembly connection to guarantee that second detection clearance 420 can detect the external diameter or the internal diameter of spare part 1000.

The second detecting head 122 has a fourth connecting hole correspondingly connected to the third connecting hole 1211 and a second positioning protrusion in positioning fit with the second positioning groove 1212, and the first detecting portion 120 includes a second fastening member 123 for fastening fit with the third connecting hole 1211 and the fourth connecting hole. In this way, the second positioning protrusion is inserted into the second positioning groove 1212, so that the fourth connection hole is correspondingly communicated with the third connection hole 1211, and then the second fastening member 123 is inserted into the fourth connection hole and the third connection hole 1211, so that the second detection head 122 and the base 121 are accurately and reliably assembled and connected.

Meanwhile, the first detection head 320 and the connecting piece 310 are accurately and reliably assembled and connected by the aid of the positioning fit of the first positioning protrusions 3242 and the first positioning grooves 312, and the second detection head 122 and the base 121 are accurately and reliably assembled and connected by the aid of the positioning fit of the second positioning protrusions and the second positioning grooves 1212, so that the first detection head 320 and the second detection head 122 are arranged at intervals relatively to form a second detection gap 420, and the requirement of inner diameter or outer diameter detection can be met.

The first detection head 320 and the second detection head 122 may be rod-shaped, strip-shaped, or block-shaped, and only the requirement of detecting the outer diameter or the inner diameter of the component 1000 is met.

As shown in fig. 9, optionally, the first detecting head 320 includes a first vertical section 324 and a first horizontal section 325 that are perpendicular to each other and connected, and a side of the first vertical section 324 away from the first horizontal section 325 is attached to and connected to the connecting member 310. In this manner, first horizontal segment 325 remains horizontally disposed by the abutment of first vertical segment 324 with the side of connector 310. As shown in fig. 9, specifically, the first vertical section 324 is provided with a second connecting hole 3241 and a first positioning protrusion 3242, and the first vertical section 324 and the connecting member 310 are accurately and reliably assembled and connected by utilizing the positioning fit between the first positioning protrusion 3242 and the first positioning groove 312 and the corresponding communication between the second connecting hole 3241 and the first connecting hole 311, in combination with the fastening effect of the first fastening member 330. The second detecting head 122 includes a second vertical section (not labeled) and a second horizontal section (not labeled) perpendicular to and connected to each other, and one side of the second vertical section, which is far away from the second horizontal section, is attached to and connected to the base 121.

Specifically, the second vertical section is provided with a fourth connecting hole and a second positioning protrusion, and the second vertical section is accurately and reliably assembled and connected with the base 121 by utilizing the positioning fit between the second positioning protrusion and the second positioning groove 1212 and the corresponding communication between the fourth connecting hole and the third connecting hole 1211 and combining the fastening effect of the second fastening member 123. The first horizontal segment 325 is spaced apart from and parallel to the second horizontal segment to form a second detection gap 420. In this way, the axial direction of the second detection gap 420 extends in the horizontal direction, so that the inner diameter or the outer diameter of the component 1000 can be accurately and reliably detected by using the second detection gap 420.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one element is considered as "fixed transmission connection" with another element, the two elements may be fixed in a detachable connection manner or in an undetachable connection manner, and power transmission can be achieved, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be achieved in the prior art, and is not cumbersome. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

It should also be understood that in explaining the connection relationship or the positional relationship of the elements, although not explicitly described, the connection relationship and the positional relationship are interpreted to include an error range which should be within an acceptable deviation range of a specific value determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
