Abstract
Description
Technical Field
[0001] This application relates to the field of inspection tool technology, and more specifically, to positioning mechanisms and inspection tools. Background Technology
[0002] A related technology provides a fixture that includes a positioning mechanism for positioning a target part during the inspection process.
[0003] However, when the positioning mechanism in the relevant technology needs to be disassembled after the inspection is completed, the positioning mechanism needs to be destroyed, which can easily cause damage to the target part. Utility Model Content
[0004] This application provides a positioning mechanism and a gauge to address the problem of how to avoid damaging the target part.
[0005] According to one aspect of this application, a positioning mechanism is provided, including a base, a push-pull member, and a slider. The base has a first channel and a second channel, which intersect and communicate with each other. The first channel extends along a first direction, and the second channel extends along a second direction. The push-pull member is movably fitted into the first channel and has a movable portion extending along the first direction. The movable portion has a first mating portion and a second mating portion at its two ends along the first direction, and the first and second mating portions are staggered along the second direction. The slider is movably fitted into the second channel and includes a first limiting portion and a second limiting portion spaced apart along the second direction. The first and second limiting portions are located on opposite sides of the movable portion along the second direction. The slider has a working position and a non-working position. In the working position, the first limiting part and the second limiting part respectively abut against the two sides of the first mating part along the second direction. In the non-working position, the first limiting part and the second limiting part respectively abut against the two sides of the second mating part along the second direction. The push-pull member is configured to drive the slider to switch between the working position and the non-working position during the movement along the first channel, thereby changing the position of the slider relative to the second channel.
[0006] The aforementioned positioning mechanism, by moving the push-pull member along a first direction, moves the first mating part to the intersection of the first and second channels, or moves the second mating part to the intersection of the first and second channels. Since the first and second mating parts are staggered along a second direction, they can drive the sliding member to move along the second direction. This change in the position of the sliding member allows for the installation or positioning of the target component, or the release of the target component's installation or positioning. Therefore, the positioning mechanism does not need to be damaged when disassembling the target component, thus avoiding damage to both the target component and the positioning mechanism during disassembly. This allows the positioning mechanism to be reused, reduces the operational intensity during disassembly, and eliminates safety hazards.
[0007] In one embodiment, the movable part further includes a guide portion. Along a first direction, the guide portion is connected between the first mating part and the second mating part, and the guide portion is used to guide the slider to switch between a working position and a non-working position.
[0008] In one embodiment, the guide portion is obliquely connected between the first mating portion and the second mating portion.
[0009] In one embodiment, the movable part has a through hole extending through it in a first direction. The sliding element includes a bolt and a guide pin. The guide pin is slidably engaged with a second channel in a second direction. The bolt includes a shank and a bolt head, the shank passing through the through hole in the second direction, one end of the shank being connected to the bolt head, and the other end of the shank being connected to the guide pin. The bolt head forms a first limiting portion, and the guide pin forms a second limiting portion.
[0010] In one embodiment, the positioning mechanism further includes a positioning element connected to one end of the slider extending out of the second channel. In the working position, the positioning element can position the target component; in the non-working position, the positioning element can release the positioning of the target component.
[0011] In one embodiment, the positioning member extends along a first direction, one end of the positioning member along the first direction is connected to the sliding member, and the other end of the positioning member along the first direction is provided with a protrusion. In the working position, the protrusion can abut against the target member.
[0012] In one embodiment, the positioning mechanism further includes an operating element connected to the end of the push-pull member away from the movable part.
[0013] In one embodiment, the thickness of the first mating part along the second direction, the thickness of the second mating part along the second direction, and the gap between the first limiting part and the second limiting part along the second direction are all equal.
[0014] In one embodiment, the first direction is perpendicular to the second direction.
[0015] According to another aspect of this application, a gauge is provided, including a gauge body and a positioning mechanism as described in any of the above embodiments, wherein a base is connected to the gauge body. Attached Figure Description

[0051] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0052] Example
[0053] Figure 1 This is a schematic diagram of the structure of the inspection tool 1 in one embodiment of this application; Figure 2 for Figure 1 A perspective view of the positioning mechanism 100 in the working position in the illustrated embodiment; Figure 3 for Figure 1 A cross-sectional view of the positioning mechanism 100 in the working position in the illustrated embodiment; Figure 4 for Figure 1 Cross-sectional view of the positioning mechanism 100 in the non-working position in the illustrated embodiment; Figure 5 for Figure 1 A schematic diagram of the push-pull member 20 in the illustrated embodiment.
[0054] See Figure 1 and Figure 2 This application provides a fixture 1, which includes a fixture body 200 and a positioning mechanism 100. The positioning mechanism 100 includes a base 10, which is connected to the fixture body 200.
[0055] When the fixture body 200 is used to inspect the target part, the positioning mechanism 100 can provide a limiting effect on the target part, ensuring that the state of the target part installed on the fixture 1 is consistent with the state of the target part installed on the vehicle, thereby improving the accuracy of the measurement results of the target part. Optionally, the target part can be a product to be inspected, such as a plastic part of a vehicle.
[0056] See Figures 2 to 4 This embodiment provides a positioning mechanism 100, including a base 10, a push-pull member 20, and a sliding member 30.
[0057] The seat 10 has a first channel 10a and a second channel 10b, which intersect and communicate with each other. The first channel 10a extends along a first direction X, and the second channel 10b extends along a second direction Y. The push-pull member 20 is movably fitted into the first channel 10a, and engages with it. Figure 5 As shown, the push-pull member 20 has a movable portion 21 extending along a first direction X. The movable portion 21 has a first mating portion 211 and a second mating portion 212 at its two ends along the first direction X, respectively. The first mating portion 211 and the second mating portion 212 are staggered along a second direction Y. The sliding member 30 is movably fitted into the second channel 10b. The sliding member 30 includes a first limiting portion 301 and a second limiting portion 302 spaced apart along the second direction Y. The first limiting portion 301 and the second limiting portion 302 are located on both sides of the movable portion 21 along the second direction Y. The slider 30 has a working position and a non-working position. In the working position, the first limiting part 301 and the second limiting part 302 respectively abut against the first mating part 211 on both sides along the second direction Y. In the non-working position, the first limiting part 301 and the second limiting part 302 respectively abut against the second mating part 212 on both sides along the second direction Y. The push-pull member 20 is configured to drive the slider 30 to switch between the working position and the non-working position during the movement along the first channel 10a, thereby changing the position of the slider 30 relative to the second channel 10b.
[0058] In use, the positioning mechanism 100 moves the push-pull member 20 along the first direction X, causing the first mating part 211 to move to the intersection of the first channel 10a and the second channel 10b, or the second mating part 212 to move to the intersection of the first channel 10a and the second channel 10b. Since the first mating part 211 and the second mating part 212 are staggered along the second direction Y, the sliding member 30 can be moved along the second direction Y. This change in the position of the sliding member 30 provides installation positioning for the target component, or releases the installation positioning of the target component. Therefore, when disassembling the target component, it is not necessary to destroy the positioning mechanism 100, thus avoiding damage to both the target component and the positioning mechanism 100 during disassembly. This allows the positioning mechanism 100 to be reused, reduces the operational intensity during disassembly, and eliminates safety hazards.
[0059] Furthermore, since the first limiting part 301 and the second limiting part 302 abut against both sides of the movable part 21 along the second direction Y in the working position, the sliding member 30 is prevented from moving in the working position, thus improving the accuracy of the measurement results of the target part. In the non-working position, the first limiting part 301 and the second limiting part 302 abut against both sides of the movable part 21 along the second direction Y, preventing the sliding member 30 from moving in the non-working position and hindering the disassembly of the target part, thus facilitating the removal of the target part and avoiding damage to the target part.
[0060] In some embodiments, such as Figure 5 As shown, the movable part 21 also includes a guide part 213. Along the first direction X, the guide part 213 connects between the first mating part 211 and the second mating part 212. Figure 3 and Figure 4 As shown, the guide portion 213 is used to guide the slider 30 to switch between the working position and the non-working position, so that the switching of the push-pull member 20 between the working position and the non-working position is smoother.
[0061] In some embodiments, such as Figure 5 As shown, the guide portion 213 is obliquely connected between the first mating portion 211 and the second mating portion 212 to further facilitate the guide portion 213 in guiding the movement of the slider 30.
[0062] In some embodiments, such as Figure 5 As shown, the movable part 21 is provided with a through hole 21a, which penetrates the movable part 21 along the first direction X. Figures 2 to 4As shown, the sliding member 30 includes a bolt 31 and a guide pin 32. The guide pin 32 is slidably fitted into the second channel 10b along the second direction Y. The bolt 31 includes a screw 312 and a bolt head 311. The screw 312 passes through the through hole 21a along the second direction Y. One end of the screw 312 is connected to the bolt head 311, and the other end of the screw 312 is connected to the guide pin 32. The bolt head 311 forms a first limiting part 301, and the guide pin 32 forms a second limiting part 302. It should be noted that a positioning mechanism is provided in the related art. This positioning mechanism uses the elastic force of an elastic element to limit the sliding member to the working position, which can easily cause the target part to loosen and fall off. In the above embodiment, since the bolt 31 and the guide pin 32 are rigidly connected, the first limiting part 301 and the second limiting part 302 can reliably abut against the movable part 21 in both the working and non-working positions. Therefore, it can be ensured that the sliding member 30 will not move in the working position, providing a stable and reliable installation or positioning function for the target part, further improving the accuracy of the measurement results of the target part, and ensuring that the sliding member 30 will not move in the non-working position to avoid affecting the disassembly of the target part. Optionally, the screw 312 is threadedly connected to the guide pin 32.
[0063] In some embodiments, such as Figures 2 to 4 As shown, the positioning mechanism 100 also includes a positioning member 40, which is connected to one end of the sliding member 30 that extends out of the second channel 10b. In the working position, the positioning member 40 can position the target part; in the non-working position, the positioning member 40 can release the positioning of the target part. Thus, by moving the sliding member 30 along the second direction Y, the positioning member 40 can be moved along the second direction Y, causing the positioning member 40 to move closer to or further away from the target part, thereby facilitating the installation and positioning of the target part or the removal of the target part.
[0064] In some embodiments, such as Figures 2 to 4 As shown, the positioning member 40 extends along the first direction X. One end of the positioning member 40 along the first direction X is connected to the sliding member 30, and the other end of the positioning member 40 along the first direction X is provided with a protrusion 41. In the working position, the protrusion 41 can abut against the target member to install or position the target member. Optionally, the surface of the protrusion 41 near the sliding member 30 along the first direction X can abut against the target member to tighten the target member.
[0065] In some embodiments, such as Figures 2 to 4As shown, the positioning mechanism 100 also includes an operating member 50, which is connected to the end of the push-pull member 20 away from the movable part 21. This allows the push-pull member 20 to be moved relative to the seat 10 along the first direction X by operating the operating member 50, thus facilitating operation. Optionally, the operating member 50 can be a handle. In use, the push-pull member 20 can be moved along the first direction X by gripping the operating member 50, thereby moving the slider 30 along the second direction Y, and thus switching the slider 30 between a working position and a non-working position.
[0066] In some embodiments, the outer surface of the operating member 50 is knurled to further facilitate pushing and pulling the operating member 50.
[0067] In some embodiments, such as Figures 3 to 5 As shown, the thickness A of the first mating part 211 along the second direction Y, the thickness B of the second mating part 212 along the second direction Y, and the gap C of the first limiting part 301 and the second limiting part 302 along the second direction Y are all equal, so as to improve the positional stability of the sliding member 30 in the working position and the non-working position, and improve the fitting accuracy of the first limiting part 301 and the second limiting part 302 with the first mating part 211 or the second mating part 212, thereby further improving the accuracy of the measurement results of the target part, and facilitating the disassembly of the target part and avoiding damage.
[0068] In some embodiments, the first direction X is perpendicular to the second direction Y. In use, the first direction X can be horizontal, and the second direction Y can be vertical.
[0069] The positioning mechanism 100 provided in this embodiment avoids damage to the target component or the positioning mechanism 100 during disassembly, reduces the workload during disassembly, simplifies and facilitates operation, eliminates safety hazards, and enables the positioning mechanism 100 to be reused, extending its service life. Furthermore, the positioning mechanism 100 can prevent the target component from loosening or falling off during detection, which helps improve the accuracy of the measurement results.
[0070] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
