[0002] With the development of the manufacturing industry, it is necessary to improve the manufacturing process quality of workpieces in order to enhance the industry's competitiveness. Therefore, it is necessary to inspect the workpieces to ensure that their quality meets the standards.

[0003] The flatness of a workpiece affects its quality. To ensure that the flatness of the workpiece meets the requirements, it is necessary to use a gauge to inspect the flatness of the workpiece.

During inspection, the workpiece must first be placed into the CMM, and then the inspection must be completed before the inspected workpiece can be removed from the CMM. Therefore, this inspection method has a long inspection time and many inspection cycles, resulting in low efficiency in inspecting the flatness of workpieces. It cannot achieve the purpose of batch inspection of a large number of workpieces, which greatly reduces the workpiece inspection efficiency in the manufacturing industry and thus cannot meet the current development needs of the manufacturing industry.

[0028] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0029] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] refer to Figures 1 to 11 A preferred embodiment of the slip flatness gauge according to this application will be described in detail below, wherein the slip flatness gauge includes a gauge body 10 and an adjustment component 20.

[0032] Specifically, the fixture body 10 includes a limiting component 11 and a deformable plate 12. The limiting component 11 includes a limiting back plate 111 and a guide plate 112. The limiting back plate 111 and the guide plate 112 are disposed opposite to each other, and the guide plate 112 is inclined to the limiting back plate 111. The side of the limiting back plate 111 facing the guide plate 112 is defined as a first limiting surface 1111. The deformable plate 12 is disposed between the limiting back plate 111 and the guide plate 112, and the deformable plate 12 has a second limiting surface 121 and a conforming guide surface 122. The side of the deformable plate 12 facing the first limiting surface 1111 is defined as the second limiting surface 121, and the second limiting surface 121 is parallel to the first limiting surface 1111, forming a sliding channel 101 between the first limiting surface 1111 and the second limiting surface 121 for the passage of a test piece 91. The side of the deformed plate 12 facing the guide plate 112 is defined as the fitting guide surface 122, which is parallel to the guide plate 112 and remains in contact with the guide plate 112.

[0033] The adjustment component 20 is disposed on the deformed plate 12 to adjust the distance between the first limiting surface 1111 and the second limiting surface 121 when the adjustment component 20 controls the deformed plate 12 to move along the inclined direction of the guide plate 112 in a manner that keeps the fitting guide surface 122 in contact with the guide plate 112, thereby adjusting the width of the sliding channel 101 to the width required for inspecting the test piece 91.

[0034] It is understood that by controlling the deformed plate 12 through the adjustment component 20 to keep the fitting guide surface 122 in contact with the guide plate 112 and moving it along the inclined direction of the guide plate 112, and after the width of the sliding channel 101 is adapted to the inspection thickness of the test piece 91, the test piece 91 can be placed into the sliding channel 101. The test piece 91 can slide through the sliding channel 101 under the action of gravity, so as to realize the inspection of the flatness of the test piece 91.

[0035] It should be noted that when the test piece 91 that meets the requirements slides through the sliding channel 101, the surface of the test piece 91 will slide over the first limiting surface 1111 and the second limiting surface 121.

[0036] As an example, if there are protrusions on the surface of the test piece 91, the overall thickness of the test piece 91 will increase, which will cause the test piece 91 to be unable to slide smoothly through the sliding channel 101, thus indicating that the test piece 91 is unqualified.

[0037] If the surface of the test piece 91 has a depression, the overall thickness of the test piece 91 will be reduced. When the test piece 91 passes through the sliding channel 101, since the surface of the test piece 91 cannot slide over the first limiting surface 1111 and the second limiting surface 121, the speed at which the test piece 91 slides through the sliding channel 101 will be faster than the speed at which a qualified test piece 91 passes through the sliding channel 101, thus indicating that the test piece 91 is unqualified.

[0038] It is worth mentioning that in this application, the flatness of the test piece 91 can be inspected simply by placing it into the sliding channel 101 and allowing it to slide down the channel 101 under the influence of gravity. Therefore, it has the advantages of short inspection time, few inspection cycles, and high inspection efficiency, thereby enabling continuous inspection of a large number of test pieces 91 to meet the needs of the manufacturing industry for inspecting the flatness of a large number of test pieces 91.

[0039] Preferably, the limiting component 11 further includes at least a pair of side plates 113. The pair of side plates 113 are disposed in an opposing manner between the limiting back plate 111 and the guide plate 112, such that the guide plate 112 is kept in an inclined manner relative to the limiting back plate 111.

[0040] In this embodiment, the adjustment assembly 20 includes a driving member 21, a fixing member 22, an adjusting member 23, and an anti-wear member 24. The driving member 21 is fixed to the deformed plate 12. The fixing member 22 is fixed to the guide plate 112. The anti-wear member 24 is sleeved on one end of the adjusting member 23 and is fixed to the driving member 21. The other end of the adjusting member 23 passes through and is threadedly connected to the fixing member 22. The extending direction of the adjusting member 23 is parallel to the contact guide surface 122.

[0041] Preferably, the adjusting member 23 is implemented as a screw, and the wear-resistant member 24 is implemented as a bearing.

[0042] It is understood that, due to the arrangement of the driving member 21, the fixing member 22, the adjusting member 23 and the anti-wear member 24, the deformed plate 12 can be fixed to the guide plate 112 in sequence by the driving member 21, the anti-wear member 24, the adjusting member 23 and the fixing member 22, so that the deformed plate 12 is stabilized between the limiting back plate 111 and the guide plate 112 in such a way that the fitting guide surface 122 is in contact with the guide plate 112, thereby stably forming the sliding channel 101.

[0043] Simultaneously, when the adjusting member 23 is rotated, the end of the adjusting member 23 near the anti-wear member 24 will rotate within the anti-wear member 24. Since the end of the adjusting member 23 away from the anti-wear member 24 passes through and is threadedly connected to the fixing member 22, the driving member 21 will move closer to and away from the fixing member 22 under the rotation of the adjusting member 23. In turn, the driving member 21 drives the deformed plate 12 to move along the inclined direction of the guide plate 112 in a manner that keeps the fitting guide surface 122 in contact with the guide plate 112, so as to adjust the distance between the first limiting surface 1111 and the second limiting surface 121, thereby adjusting the width of the sliding channel 101 to the width for inspecting the test piece 91.

[0044] It is worth mentioning that, since the width of the sliding channel 101 is adjustable, the test piece 91 with different thicknesses can enter the sliding channel 101 to achieve the purpose of inspecting the flatness of the test piece 91 with different thicknesses, without the need to remanufacture a new inspection fixture, thus saving manufacturing costs.

[0045] In another modified embodiment, the adjustment assembly 20 includes a driving member 21, a fixing member 22, and an adjusting member 23. The driving member 21 is fixed to the deformed plate 12. The fixing member 22 is fixed to the guide plate 112. The adjusting member 23 is disposed between the driving member 21 and the fixing member 22. The driving member 21 is disposed at the output end of the adjusting member 23 in a manner that allows it to approach and move away from the fixing member 22. Both the driving member 21 and the fixing member 22 are in a direction in which the deformed plate 12 moves along the inclined direction of the guide plate 112 in a manner that keeps the fitting guide surface 122 in contact with the guide plate 112.

[0046] Preferably, the adjusting member 23 is implemented as a telescopic cylinder.

[0047] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the adjustment component 20 is described only as an example of the drive member 21, the fixing member 22, the adjustment member 23, and the anti-wear member 24.

[0048] Specifically, the guide plate 112 has at least one guide groove 11201. The extending direction of the guide groove 11201 is parallel to the extending direction of the adjusting member 23. The fixture body 10 also includes at least one guide restrictor 13 corresponding to the guide groove 11201. The guide restrictor 13 is fixed to the deformed plate 12 by passing through the guide groove 11201, and the portion of the guide restrictor 13 passing through the guide groove 11201 is adapted to the inner wall of the guide groove 11201.

[0049] Preferably, the guide restraint 13 is implemented by including screws.

[0050] It is understood that when the driving member 21 drives the deformed plate 12 to move along the inclined direction of the guide plate 112 in such a way that the fitting guide surface 122 is attached to the guide plate 112, since the extension direction of the guide groove 11201 is parallel to the extension direction of the adjusting member 23, the guide restricting member 13 will slide in the extension direction within the guide groove 11201 to restrict the sliding direction of the guide restricting member 13 through the inner wall of the guide groove 11201, thereby restricting the sliding direction of the deformed plate 12. At the same time, the guide restricting member 13 makes the deformed plate 12 movably held between the restricting back plate 111 and the guide plate 112 in such a way that the fitting guide surface 122 is attached to the guide plate 112.

[0051] Preferably, the deformed plate 12 has a detection adapter groove 1201 formed at the fitting guide surface 122, and the bottom wall of the detection adapter groove 1201 is parallel to the limiting back plate 111. The slippage flatness gauge further includes a detection element 30, which has a detection end. The detection element 30 is installed on the guide plate 112, and the detection end of the detection element 30 is configured to penetrate the guide plate 112 and press against the bottom wall of the detection adapter groove 1201.

[0052] Preferably, the detection element 30 is implemented to include a dial gauge.

[0053] It is understood that, since the bottom wall of the detection adapter groove 1201 is parallel to the limiting back plate 111, and the detection end of the detection member 30 is configured to penetrate the guide plate 112 and press against the bottom wall of the detection adapter groove 1201, when the driving member 21 drives the deformed plate 12 to move along the inclined direction of the guide plate 112 in a manner that keeps the fitting guide surface 122 in contact with the guide plate 112, the detection end of the detection member 30 will slide along the extension direction of the detection adapter groove 1201 in a manner that presses against the bottom wall of the detection adapter groove 1201. At this time, the extension and retraction stroke of the detection end is the change in the width dimension of the sliding channel 101.

[0054] As an example, the deformed plate 12 is moved along the inclined direction of the guide plate 112 by the driving member 21 to keep the fitting guide surface 122 in contact with the guide plate 112, and after the second limiting surface 121 of the deformed plate 12 is pressed against the first limiting surface 1111, the detection value of the detection member 30 is set to zero. Then, the width dimension of the sliding channel 101 can be obtained by detecting the change in the extension stroke of the detection end when it slides along the extension direction of the detection adapter groove 1201 while pressing against the bottom wall of the detection adapter groove 1201.

[0055] In other words, after the detection value of the detection element 30 is set to zero, when the detection end of the detection element 30 slides along the extension direction of the detection adapter groove 1201 while pressing against the bottom wall of the detection adapter groove 1201, the extension stroke of the detection end is the width dimension of the sliding channel 101. Therefore, there is no need to use other tools to measure the width dimension of the sliding channel 101, thereby improving the efficiency of adjusting the width dimension of the sliding channel 101.

[0056] Preferably, the main body 10 of the inspection tool further includes a stabilizing member 14, which is fixed to the guide plate 112 and sleeved on the detection end of the detection member 30, so as to improve the stability of the detection end and reduce the occurrence of the detection end being skewed.

[0057] Preferably, the length of the second limiting surface 121 of the deformed plate 12 is greater than the length of the first limiting surface 1111, and the higher end of the second limiting surface 121 in the gravity direction is defined as a receiving part. The receiving part is not opposite to the first limiting surface 1111, so that after the test piece 91 is placed in the receiving part, the test piece 91 slides into the sliding channel 101 under the action of gravity, reducing the operation time when aligning the test piece 91 into the sliding channel 101, thereby improving the efficiency of inspecting the flatness of the test piece 91.

[0058] Those skilled in the art will understand that the size of the receiving part should not be smaller than the projected size of the test piece 91 (not shown in the figure) to prevent the receiving part from being unable to receive the test piece 91.

[0059] Preferably, the inspection fixture body 10 further includes a protective plate 15, which is connected to the guide plate 112, and the protective plate 15 has a protective channel, through which the inspection piece 30 is partially disposed.

[0060] Preferably, the protective plate 15 is made of plexiglass so that the state of the detection element 30 disposed on the guide plate 112 can be observed through the protective plate 15, so as to detect and deal with the skewness of the detection element 30 in a timely manner.

[0061] It is worth mentioning that, due to the setting of the protective plate 15, the protective plate 15 can not only reduce the situation where the detection element 30 is tilted due to external impact, but also, since the detection element 30 partially passes through the protective channel of the protective plate 15, the state of the detection element 30 when passing through the protective channel can be observed in time to detect whether the detection element 30 is tilted, so that the tilting of the detection element 30 can be detected and dealt with in a timely manner.

[0062] Preferably, the slip-out flatness gauge further includes a mounting body 40. The mounting body 40 includes a pair of support members 41. The pair of support members 41 are respectively disposed on the pair of side plates 113, so as to elevate the gauge body 10, the adjustment assembly 20 and the detection element 30 by means of the pair of support members 41, so as to catch the test element 91 after it slides through the slip-out channel 101.

[0063] As an example, a container can be placed at the end of the sliding channel 101 in the direction of gravity to collect the test piece 91 that has slid through the sliding channel 101.

[0064] More preferably, the support member 41 includes a connector 411 and a support member 412. The mounting body 40 also includes a pair of shaft members 42. The connectors 411 of the pair of support members 41 are respectively mounted on the pair of side plates 113, and the pair of support members 412 each has a rotating hole 41201 for receiving the shaft member 42. One end of each pair of shaft members 42 is respectively fixed to the pair of connectors 411. The other end of each pair of shaft members 42 is rotatably inserted into the rotating hole 41201 of the pair of support members 412.

[0065] It is understood that after the inspection fixture body 10, the adjustment component 20 and the detection component 30 drive the connecting component 411 to rotate around the shaft component 42, the angle of the sliding channel 101 in the direction of gravity can be adjusted, thereby changing the time required for the test piece 91 to pass through the sliding channel 101, and also changing the speed of the test piece 91 after passing through the sliding channel 101.

[0066] It should be noted that when the test piece 91 is unqualified and has a small overall thickness, the speed of the unqualified test piece 91 after passing through the sliding channel 101 will be greater than the speed of the qualified test piece 91 after passing through the sliding channel 101. After changing the angle of the sliding channel 101 in the direction of gravity, the speed of the qualified test piece 91 and the unqualified test piece 91 after passing through the sliding channel 101 will be easier to observe, so as to remove the unqualified test piece 91 with a small overall thickness.

[0067] Preferably, each of the pair of support members 412 has a locking hole 41202. The locking hole 41202 communicates with the rotating hole 41201. The mounting body 40 also includes a pair of locking members 43. Each locking member 43 includes a locking body 431. The pair of locking bodies 431 are threadedly connected to the inner wall of the locking hole 41202 of the pair of support members 412 in a manner that can press against the pair of shaft members 42, so that by adjusting the depth of the threaded connection of the locking body 431 to the locking hole 41202, the entire assembly of the inspection fixture body 10, the adjustment component 20, and the inspection member 30 is locked after the connecting member 411 rotates around the shaft member 42.

[0068] In other words, after the fixture body 10, the adjustment component 20 and the detection component 30 are rotated together to a predetermined angle around the shaft component 42, the locking body 431 is threadedly connected to the locking hole 41202, and the locking body 431 is pressed against the shaft component 42 to lock the overall angle of the fixture body 10, the adjustment component 20, the detection component 30 and the connecting component 411 in the direction of gravity.

[0069] Preferably, the locking member 43 further includes an assisting member 432. A pair of assisting members 432 are respectively connected to the ends of the locking body 431 away from the shaft member 42, and the extending directions of the pair of assisting members 432 are respectively offset from the extending directions of the pair of locking bodies 431, so as to assist in rotating the locking body 431 by means of the assisting members 432.

[0070] Preferably, the slip flatness gauge further includes a display component 50. The display component 50 includes an arc-shaped plate 51 and an indicator 52. The arc-shaped plate 51 is disposed on the support member 412. The indicator 52 is disposed on the connector 411. The arc-shaped plate 51 has a plurality of scale grooves formed along its edge. The indicator 52 is close to the arc-shaped plate 51, and the indicator 52 has a pointer groove, which corresponds to one of the scale grooves of the arc-shaped plate 51.

[0071] As an example, during the rotation of the connecting member 411 around the shaft member 42 by the entire assembly of the fixture body 10, the adjustment component 20, and the detection component 30, the indicator 52 will slide along the edge of the arc plate 51 so that the pointer groove of the indicator 52 points to different scale grooves of the arc plate 51, thereby displaying the angle of rotation of the connecting member 411 around the shaft member 42 by the entire assembly of the fixture body 10, the adjustment component 20, and the detection component 30, so as to facilitate control of the rotation angle.

[0072] In this embodiment, a plurality of slits 1202 are formed at the fitting guide surface 122 of the deformed plate 12 to prevent the fitting guide surface 122 and the guide plate 112 from being pressed together by atmospheric pressure due to excessive smoothness. Simultaneously, the presence of the plurality of slits 1202 reduces the contact area between the fitting guide surface 122 and the guide plate 112, thereby increasing the friction between them and preventing slippage. Alternatively, the slits 1202 can also be formed at the contact point between the guide plate 112 and the fitting guide surface 122.

[0073] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
