In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.

As shown in fig. 1, a first embodiment of the present application provides an inspection tool 100 for inspecting whether a hole 210 in a workpiece 200 is acceptable. Referring to fig. 2-3, the workpiece 200 is a frame structure, the required inspection holes 210 are located on the inner side of the workpiece 200 and are arranged obliquely, and the inspection tool of the present application is used for inspecting the inclination angle of the holes 210 and the end surface positions of the holes 210. Referring to fig. 4, the inspection tool 100 includes a support 10, a slide rod 20, a pressing member 30, and an elastic member 40, wherein the support 10 is used for supporting a workpiece 200 to position the inspection tool 100. The sliding rod 20 is movably disposed on the bracket 10, the sliding rod 20 includes a rod portion 21 and an insertion portion 22 connected to each other, the insertion portion 22 is inserted into the hole 210, a step surface 23 is formed between the insertion portion 22 and the rod portion 21, and the step surface 23 is used for abutting against an end surface 220 of the hole 210. The sliding rod 20 is further provided with a mark 24, and the mark 24 is used for indicating the insertion condition of the insertion portion 22 so as to indirectly judge whether the hole 210 is qualified. The pressing piece 30 is connected to an end of the rod portion 21 facing away from the insertion portion 22. The elastic member 40 is sleeved on the sliding rod 20 and elastically supports the pressing member 30 and the bracket 10.

When the slide bar 20 is slidably coupled to the holder 10 and the holder 10 is mounted on the workpiece 200, the pressing member 30 is biased to slide the slide bar 20, thereby attempting to insert the insertion portion 22 of the slide bar 20 into the hole 210. At the same time, the mark 24 on the slide bar 20 is displaced as the insertion portion 22 is moved. By the position of the mark 24, the user can determine the movement of the insertion portion 22, and indirectly determine the size of the hole 210. After the detection is finished, the pressing piece 30 is released, the elastic piece 40 abuts against the pressing piece 30, and the detection tool 100 is reset so as to carry out the next detection.

With the above-mentioned detection tool 100, when the angular direction of the hole 210 does not conform to the preset value, the movement of the insertion portion 22 is easily hindered, or the insertion portion 22 cannot be inserted into the hole 210, so that the step surface 23 cannot abut against the end surface 220 of the hole 210, and at this time, the position of the mark 24 is relatively outward away from the bracket 10. When the angle of the hole 210 is preset, the insertion portion 22 of the sliding rod 20 can be inserted smoothly and unimpededly, so that the step surface 23 abuts against the end surface 220 of the hole 210, and at this time, the position of the mark 24 is relatively close to the inner side of the bracket 10, and whether the angle of the hole 210 is preset or not is judged.

When the angle of the hole 210 is in accordance with the preset, the insertion portion 22 may be completely inserted into the hole 210 until the step surface 23 abuts against the end surface 220 of the hole 210. At this time, by the position of the mark 24, it can be judged whether the end face of the hole 210 is within the preset tolerance band, so as to detect the position of the end face 220 of the hole 210. Specifically, if the end face 220 is excessively machined in the CNC machining, that is, the position of the end face 220 is deep relative to the preset position, the length of the insertion hole 210 of the slide rod 20 is excessively long, and the exposed size of the mark 24 on the slide rod 20 relative to the bracket 10 is excessively small; if the machining amount of the end surface 220 is small at the time of CNC machining, that is, the position of the end surface 220 is shallow with respect to the preset position, the length of the insertion hole 210 of the slide rod 20 is short, and the exposed size of the mark 24 on the slide rod 20 with respect to the bracket 10 is large. Thus, the position of the end surface 220 can be determined by the mark 24.

In this manner, the dimensions of the hole 210 are converted to the slider 20 for display to allow for rapid inspection of the hole 210.

In an embodiment, referring to fig. 2, the bracket 10 is provided with a notch 111, and the notch 111 is used for exposing the mark 24. Since the elastic member 40 abuts against the bracket 10 and the pressing member 30, the mark 24 is disposed at a position which is not covered by the elastic member 40, so as to prevent the elastic member 40 from interfering the user to observe the mark 24. Correspondingly, a notch 111 is provided in the holder 10 to expose the mark 24 for the user to observe.

In one embodiment, the frame 10 further has an indication area (not shown) located on the sidewall of the notch 111 for matching with the mark 24 to show the end position of the hole 210. The position of the indication area is adjacent to the notch 111 for providing an indication for the moving range of the mark 24, so that the user can judge the insertion length of the sliding rod 20 through the corresponding position of the mark 24 in the indication area.

In one embodiment, referring to fig. 5, the angle α between the sliding rod 20 and the horizontal direction is equal to the predetermined angle between the end surface of the hole 210 and the vertical direction. The angle of the sliding rod 20 is preset so that the sliding rod 20 can slide along the angle of the hole 210, and the purpose of detecting the inclination of the hole 210 by the sliding rod 20 is achieved while the structure is simplified.

In an embodiment, referring to fig. 2, the bracket 10 includes a main body 11, and a first supporting portion 12 and a second supporting portion 13 respectively connected to the main body 11, the first supporting portion 12 extends along a first direction, the second supporting portion 13 extends along a second direction, the first direction and the second direction are disposed at an angle to form an approximately L shape, and both the first supporting portion 12 and the second supporting portion 13 are used for supporting the workpiece 200.

The workpiece 200 in this embodiment is a frame, and therefore the first supporting portion 12 and the second supporting portion 13 are respectively arranged on two adjacent rods of the workpiece 200 to support and position the inspection tool 100. The hole 210 is then detected by pressing the sliding rod 20, and the first supporting portion 12 and the second supporting portion 13 indirectly bear the pressure of the sliding rod 20, so as to detect the hole 210.

In an embodiment, referring to fig. 5, the main body 11 has a guide slot 112, the rod 21 is partially received in the guide slot 112, such that the rod 21 of the sliding rod 20 slides along the direction of the guide slot 112, and the guide slot 112 plays a role of orientation and position limitation, thereby ensuring that the sliding rod 20 moves in a predetermined direction, and improving the detection accuracy.

In an embodiment, referring to fig. 4-5, the rod portion 21 is provided with a protruding limiting portion 211, and the limiting portion 211 and the pressing member 30 are respectively located at two sides of the main body portion 11 to prevent the slide rod 20 from being separated from the bracket 10. When the user applies an acting force to the pressing member 30 to detect the hole 210, the elastic member 40 drives the pressing member 30 to reset the sliding rod 20, and the limiting portion 211 abuts against the bracket 10 to prevent the sliding rod 20 from separating from the bracket 10 from above.

In an embodiment, a first profiling surface 121 is disposed at an end of the first supporting portion 12 away from the main body portion 11, a second profiling surface 131 is disposed at an end of the second supporting portion 13 away from the main body portion 11, and the first profiling surface 121 and the second profiling surface 131 are used for abutting against the workpiece 200. The first profiling surface 121 and the second profiling surface 131 abut against the side wall of the workpiece 200 and are respectively adapted to the shape of the abutted side wall surface, so that the positioning effect of the bracket 10 on the workpiece 200 is improved, the detection tool 100 is more firmly fixed on the workpiece 200, the bracket 10 is prevented from shifting during detection, and the accuracy of the detection result is improved.

In an embodiment, the pressing element 30 defines a cavity 31, and an end portion of the sliding rod 20 away from the insertion portion 22 is received in the cavity 31, such that the pressing element 30 is disposed at the end portion of the sliding rod 20. The detecting tool 100 further includes a locking member 50, wherein the pressing member 30 has a positioning slot 32, and the locking member 50 is received in the positioning slot 32 and abuts against the sliding rod 20 for locking the pressing member 30 to the sliding rod 20. The locking member 50, which may include a bolt, a screw, etc., passes through the positioning groove 32 and abuts against one side of the slide rod 20 to lock the pressing member 30. The pressing member 30 is fixed to the slide bar 20 by the locking member 50, thereby facilitating replacement or adjustment of the pressing member 30.

In an embodiment, the length of the insertion portion 22 is less than or equal to the depth of the hole 210, so as to prevent the step surface 23 from being unable to abut against the end surface 220 of the hole 210 due to the too long insertion portion 22, and thus the position of the end surface 220 of the hole 210 cannot be detected.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.

Although the present application has been described in detail with reference to preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present application.
