[0038] The invention provides a proximity switch detection jig.

[0039] like Figures 1 to 3 As shown, in one embodiment of the present invention, a proximity switch detection fixture 100 includes a base 10, a clamping member 30, and a plurality of blocking members 50 of different thicknesses. The base 10 is provided with an installation station 10a, and the installation station 10a is used to install the proximity switch. The clamping member 30 is slidably connected to the base 10, and the clamping member 30 can be close to or away from the installation station 10a. The clamping member 30 is used to clamp the detection member. The blocking member 50 is connected to the base 10. Among them, the base 10 is provided with a blocking position between the installation station 10a and the clamping member 30, and the blocking member 50 can be moved to the blocking position.

[0040] In this embodiment, the base 10 is provided with an installation station 10a, and the installation station 10a is used to install the proximity switch. The clamping member 30 for clamping the detection member is slidably connected to the base 10 and can be close to or away from the installation station 10a to adjust the detection member to a position where the proximity switch generates induction. A plurality of blocking members 50 of different thicknesses can be moved to the blocking position, that is, the blocking member 50 can be moved to the blocking position to separate the proximity switch and the detection member; the blocking member 50 can also be moved away from the blocking position to make the proximity switch and the detection member unobstructed. The proximity switch has an induction direction, and the connection line of the installation station 10a and the clamping member 30 is the connection line of the proximity switch and the detection member along the induction direction. One blocking member 50 avoids another blocking member 50 on the connection line of the installation station 10a and the clamping member 30, that is, when one blocking member 50 moves to the blocking position, the other blocking member 50 needs to be moved away from the blocking position to avoid overlapping between blocking members 50 of different thicknesses and affecting detection. By moving a plurality of blocking members 50 of different thicknesses to the blocking position between the installation station 10a and the clamping member 30, the penetration sensing ability of the proximity switch for baffles of different thicknesses is tested. Compared with manual detection, the present invention does not require manual holding of the detection member, nor does it require manual removal and placement of baffles of different thicknesses. By moving the blocking member 50 on the proximity switch detection fixture 100, the sensing ability of the proximity switch through baffles of different thicknesses can be tested, thereby reducing the labor intensity of the manual labor, increasing the test speed, and further increasing the efficiency of detecting the proximity switch.

[0041] In addition, it should be noted that the plurality of blocking members 50 of different thicknesses may be 2, 3, 4, 5, 6, etc. There is no limitation on the number of blocking members 50, and a corresponding number of blocking members 50 may be set according to the needs of proximity switch detection.

[0042] The thickness of the blocking member 50 may be 1 mm, 1.5 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc. There is no limitation on the thickness of the blocking member 50 , and the blocking member 50 of corresponding thickness may be set according to the needs of proximity switch detection.

[0043] The plurality of blocking members 50 of different thicknesses may be arranged in blocks, that is, each blocking member 50 is independent of each other; the plurality of blocking members 50 of different thicknesses may also be arranged in an integral structure, that is, the plurality of blocking members 50 of different thicknesses are manufactured and formed in one piece.

[0044] In some embodiments, the clamping member 30 can be moved closer to or further away from the installation station 10a by setting a screw assembly, for example, by rotating the screw to drive the clamping member 30 fixedly connected to the nut; the clamping member 30 can also be driven by a linear motor; it can also be pushed manually; or there can be other ways to move the clamping member 30 closer to or further away from the installation station 10a.

[0045] The blocking member 50 can be moved to the blocking position by rotating the lead screw to drive the blocking member 50; it can also be driven by a linear motor; it can also be pushed manually; or it can be moved to the blocking position in other ways.

[0046] like Figures 1 to 3 As shown, in one embodiment of the present invention, the blocking member 50 is slidably connected to the base 10, and the blocking member 50 slides in a direction perpendicular to the line connecting the clamping member 30 and the installation station 10a.

[0047] In this embodiment, the blocking member 50 slides along the direction perpendicular to the line connecting the clamping member 30 and the installation station 10a, that is, the sensing direction of the proximity switch installed on the installation station 10a. That is, the blocking member 50 slides along the sensing direction perpendicular to the line connecting the clamping member 30 and the installation station 10a. By slidingly connecting the blocking member 50 with the base 10, the blocking member 50 slides, which not only facilitates switching of blocking members 50 of different thicknesses to improve the efficiency of detecting the proximity switch, but also makes the sliding connection easy to implement, facilitates manufacturing and processing, and saves production costs.

[0048] In addition, it should be noted that the sliding connection between the blocking member 50 and the base 10 can be achieved by opening a sliding groove on the base 10 and connecting the blocking member 50 with the sliding groove to achieve the sliding of the blocking member 50; or by setting a track on the base 10 and connecting the blocking member 50 with the track to achieve the sliding of the blocking member 50; or other effective ways to achieve the sliding of the blocking member 50 can be used.

[0049] like Figures 1 to 3 As shown, in one embodiment of the present invention, the base 10 is further provided with a first slide groove 10b and a second slide groove 10c, the first slide groove 10b is provided on the connecting line between the clamping member 30 and the installation station 10a, and the clamping member 30 is slidably connected to the first slide groove 10b. The second slide groove 10c is perpendicular to the first slide groove 10b, and the second slide groove 10c is located between the first slide groove 10b and the installation station 10a, and the blocking member 50 is slidably connected to the second slide groove 10c.

[0050] In this embodiment, the connection line between the clamping member 30 and the installation station 10a is the connection line between the proximity switch and the detection member along the sensing direction. The first slide 10b is arranged on the connection line between the clamping member 30 and the installation station 10a, that is, the first slide 10b is arranged on the connection line between the proximity switch and the detection member along the sensing direction. The clamping member 30 slides along the length direction of the first slide 10b, so that the detection member clamped on the clamping member 30 is close to or away from the proximity switch. Compared with the method of manually grasping the detection member to move, the first slide 10b in this embodiment of the present invention can make the detection member move linearly along the sensing direction, and will not cause the detection member to deviate from the sensing direction due to the moving detection member, causing test deviation, which can effectively ensure that the detection member is in the sensing direction of the proximity switch, thereby effectively improving the accuracy of detecting the proximity switch, thereby improving the reliability of the proximity switch detection result. In addition, the first slide 10b is opened on the base 10, which has a simple structure, is easy to manufacture and process, and can save production costs.

[0051] The first slide groove 10b has two opposite ends in the length direction, one of which faces the installation station 10a. The second slide groove 10c is close to the end of the first slide groove 10b facing the installation station 10a, that is, the second slide groove 10c is located between the first slide groove 10b and the installation station 10a. The second slide groove 10c is perpendicular to the first slide groove 10b, that is, the length direction of the second slide groove 10c is perpendicular to the length direction of the first slide groove 10b, that is, the second slide groove 10c is perpendicular to the sensing direction.

[0052] The blocking member 50 slides along a direction perpendicular to the line connecting the clamping member 30 and the installation station 10a, so that the blocking member 50 moves to the blocking position or moves away from the blocking position. Compared with the method of manually taking the blocking member 50 for replacement, the second slide groove 10c in this embodiment of the present invention can make the blocking member 50 move in a straight line along a direction perpendicular to the sensing direction, and will not cause the blocking member 50 to be non-perpendicular to the sensing direction due to the movement of the blocking member 50, causing a test deviation, that is, it can be avoided that the thickness of the blocking member 50 in the sensing direction changes during the test, so that it can be effectively ensured that the thickness of the blocking member 50 in the sensing direction is the measured thickness of the blocking member 50, so that the thickness in the sensing direction will not increase due to the offset of the blocking member 50 itself, so that the accuracy of detecting the proximity switch can be effectively improved, thereby improving the reliability of the proximity switch detection result. In addition, the second slide groove 10c is provided on the base 10, which has a simple structure, is easy to manufacture and process, and can save production costs.

[0053] like Figures 1 to 3As shown, in one embodiment of the present invention, the proximity switch detection fixture 100 further includes a first moving assembly 70 and a second moving assembly 90, wherein the first moving assembly 70 is mounted on the base 10, and the first moving assembly 70 is connected to the clamping member 30, and the first moving assembly 70 is used to drive the clamping member 30 to move. The second moving assembly 90 is mounted on the base 10, and the second moving assembly 90 is connected to the blocking member 50, and the second moving assembly 90 is used to drive the blocking member 50 to move.

[0054] In this embodiment, the first moving assembly 70 drives the clamping member 30 to move, and the second moving assembly 90 drives the blocking member 50 to move, so that manual pushing and movement are not required, thereby saving labor and improving detection efficiency.

[0055] In addition, it should be noted that the first moving assembly 70 may drive the clamping member 30 to move by rotating a screw rod, or by a linear motor, or by other effective ways to move the clamping member 30 .

[0056] The second moving assembly 90 may drive the blocking member 50 to move by rotating a lead screw, or by a linear motor, or by other effective ways to move the blocking member 50 .

[0057] The connection between the first moving assembly 70 and the clamping member 30 may be a fixed connection, a detachable connection, or other effective connection methods.

[0058] The second moving assembly 90 and the blocking member 50 may be connected in a fixed manner, in a detachable manner, or in other effective connection modes.

[0059] like Figures 1 to 3 As shown, in one embodiment of the present invention, the first moving assembly 70 includes a first screw rod 71, a first nut 73 and a first motor (not shown in the figure), the first screw rod 71 is installed in the first slide slot 10b, the first nut 73 is provided on the first screw rod 71 and is threadedly connected to the first screw rod 71, the first nut 73 is fixedly connected to the clamping member 30, the first motor is installed on the base 10, and is transmission-connected to the first screw rod 71 to drive the first screw rod 71 to rotate. The second moving assembly 90 includes a second screw rod 91, a second nut 93 and a second motor (not shown in the figure), the second screw rod 91 is installed in the second slide slot 10c, the second nut 93 is provided on the second screw rod 91 and is threadedly connected to the second screw rod 91, the second nut 93 is fixedly connected to the blocking member 50, the second motor is installed on the base 10, and is transmission-connected to the second screw rod 91 to drive the second screw rod 91 to rotate.

[0060] In this embodiment, the rotation of the first motor drives the first screw rod 71 to rotate. As the first screw rod 71 rotates, the first thread sleeved on the first screw rod 71 moves along the length direction of the first screw rod 71, thereby driving the clamping member 30 to move. Compared with the manual pushing method, the present embodiment of the present invention can save labor and improve the detection efficiency, and the screw rod drives the clamping member 30 to move to accurately adjust the distance between the proximity switch and the detection detector installed on the clamping member 30, and can achieve fine adjustment of the distance, thereby improving the accuracy of the detection. The rotation of the second motor drives the second screw rod 91 to rotate. As the second screw rod 91 rotates, the second thread sleeved on the second screw rod 91 moves along the length direction of the second screw rod 91, thereby driving the blocking member 50 to move. Compared with the manual pushing method, the present embodiment of the present invention can save labor and improve the detection efficiency.

[0061] like Figures 1 to 3 As shown, in one embodiment of the present invention, a plurality of blocking members 50 with different thicknesses are an integrated structure, and one side surface of the integrated structure formed by combining the plurality of blocking members 50 is in a stepped shape.

[0062] In this embodiment, a plurality of blocking members 50 of different thicknesses are an integrated structure, that is, a plurality of blocking members 50 of different thicknesses are integrally formed. A plurality of blocking members 50 of different thicknesses can be manufactured and formed at one time, without having to be manufactured in batches, thereby improving manufacturing efficiency and saving manufacturing costs. One side of the integrated structure formed by a plurality of blocking members 50 of different thicknesses is in a stepped shape. The stepped shape allows the thickness of the integrated structure to increase from small to large. When testing the proximity switch, the integrated structure can be pushed to slide to the blocking position. As the integrated structure slides, the thickness of the integrated structure on the line connecting the proximity switch and the detection member can be increased from small to large, or the thickness of the integrated structure on the line connecting the proximity switch and the detection member can be decreased from large to small, thereby providing two different detection methods, so that the proximity switch detection fixture 100 can meet more detection requirements and expand the applicability of the proximity switch detection fixture 100. Moreover, such a configuration can make the thickness of the integrated structure on the line connecting the proximity switch and the detection member increase from small to large, so as to detect the proximity switch, and then make the thickness of the integrated structure on the line connecting the proximity switch and the detection member decrease from large to small, so as to verify the accuracy of the proximity switch detection; or, first make the thickness of the integrated structure on the line connecting the proximity switch and the detection member decrease from large to small, and then make the thickness of the integrated structure on the line connecting the proximity switch and the detection member increase from small to large after the proximity switch detection, so as to verify the accuracy of the proximity switch detection. This embodiment of the present invention provides a reliable verification method for the detection of the proximity switch, thereby further improving the detection reliability of the proximity switch detection fixture 100.

[0063] like Figures 1 to 3As shown, in one embodiment of the present invention, the proximity switch detection fixture 100 further includes a first measuring piece, which is detachably connected to the base 10 and is used to measure the thickness of the blocking member 50 .

[0064] In this embodiment, the first measuring piece is detachably connected to the base 10. Specifically, the first measuring piece is detachably connected to the upper surface of the base 10, close to or located at the connection line between the proximity switch and the detection piece, so that when the blocking piece 50 moves to the blocking position, the first measuring piece is close to or attached to the blocking piece 50, so as to measure the thickness of the blocking piece 50 on the connection line between the proximity switch and the detection piece. As shown in the configuration, on the one hand, the first measuring piece can detect the thickness of the blocking piece 50, so as to accurately obtain the thickness values ​​of the blocking pieces 50 of different thicknesses, and then obtain the influence of the blocking pieces 50 of different thicknesses on the proximity switch; on the other hand, the first measuring piece can be easily replaced. When the first measuring piece is damaged or the measurement is inaccurate, the first measuring piece can be removed from the base 10, and then a new first measuring piece can be installed on the base 10. Therefore, when the first measuring piece fails, it is not necessary to replace the entire proximity switch detection fixture 100, but only the first measuring piece needs to be replaced, thereby extending the service life of the proximity switch detection fixture 100 and effectively saving costs.

[0065] In addition, it should be noted that the first measuring member can be detachably connected to the base 10 by a slot-type connection, a magnetic connection, or other effective detachable connection methods.

[0066] The first measuring member may be a ruler, an electronic distance meter, or other means for measuring the distance between the blocking member 50 and the detecting member.

[0067] like Figures 1 to 3 As shown, in one embodiment of the present invention, the first measuring member is a ruler.

[0068] In this embodiment, the thickness of the blocking member 50 can be measured quickly and conveniently by using a ruler to measure the side where the thickness of the blocking member 50 changes. In addition, the ruler is easy to read values, measures accurately, and is cheap, which can effectively reduce costs.

[0069] like Figures 1 to 3 As shown, in one embodiment of the present invention, the proximity switch detection fixture 100 further includes a second measuring piece, which is connected to the base 10 and is used to measure the distance between the proximity switch and the detection piece.

[0070] In this embodiment, the second measuring piece is connected to the base 10, and the second measuring piece can measure the distance between the proximity switch and the detection piece, that is, can detect the sensing distance of the proximity switch. Specifically, the detection piece is moved close to the proximity switch, and when the proximity switch generates induction, the movement of the detection piece is stopped, and the distance between the detection piece and the proximity switch at this time is measured by the second measuring piece, so that the sensing distance of the proximity switch can be obtained. With such a configuration, the proximity switch detection fixture 100 can not only test the sensing ability of the proximity switch through baffles of different thicknesses, but also measure the sensing distance of the proximity switch, so that the proximity switch detection fixture 100 can meet more detection needs, thereby expanding the applicability of the proximity switch detection fixture 100.

[0071] In addition, it should be noted that the second measuring member may be connected to the base 10 by a fixed connection via bolts, or by a detachable connection via a slot, or by other effective connection methods.

[0072] The second measuring member may be a ruler, an electronic distance meter, or other methods for measuring the distance between the blocking member 50 and the detecting member.

[0073] like Figures 1 to 3 As shown, in one embodiment of the present invention, the second measuring member is a ruler, the length direction of the second measuring member is parallel to the connection direction of the clamping member 30 and the installation station 10a, and is arranged close to the first slide groove 10b.

[0074] In this embodiment, a ruler is used to measure the distance between the blocking member 50 and the clamping member 30, so that the sensing distance of the blocking member 50 can be measured quickly and conveniently. Specifically, the length direction of the second measuring member is parallel to the connecting direction of the clamping member 30 and the installation station 10a, that is, the length direction of the second measuring member is consistent with the sensing direction, so as to facilitate the measurement of the sensing distance of the proximity switch. The ruler is easy to read the value, the measurement is accurate, and the price is cheap, which can effectively reduce the cost.

[0075] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the blocking member 50 is made of bakelite.

[0076] In this embodiment, the material of the blocking member 50 is bakelite, which is a kind of plastic. It has high mechanical strength, good insulation, heat resistance, corrosion resistance, and good plasticity. Since bakelite is cheap, using bakelite to make the blocking member 50 can effectively reduce the manufacturing cost, and bakelite has good plasticity and is easy to shape, which can reduce the processing steps after shaping, thereby further reducing the manufacturing cost. The detection member is an iron product, and the proximity switch used can generate induction to iron, so the performance of the proximity switch penetrating the plastic to sense the iron product can be detected.

[0077] The present invention further provides a detection device, which includes a control platform (not shown) and a proximity switch detection fixture 100, and the control platform is connected to the proximity switch detection fixture 100. The specific structure of the proximity switch detection fixture 100 refers to the above embodiment. Since the present detection device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0078] In one embodiment of the detection device of the present invention, the control platform is connected to the proximity switch detection fixture 100, and the control platform is used to control the working states of the first motor and the second motor respectively, so as to respectively control the movement of the detection member and the blocking member 50. The control platform is also used to calculate the distance between the proximity switch and the detection member according to the moving distance of the detection member. The control platform is also used to control the blocking members 50 of different thicknesses to move to the blocking position according to the requirements.

[0079] Specifically, the control platform is electrically connected to the first motor, thereby controlling the rotation of the first motor, and then controlling the rotation of the first screw rod 71, and then controlling the movement of the first nut 73, and then controlling the movement of the detection member clamped on the clamp 30. The control platform is electrically connected to the second motor, thereby controlling the rotation of the second motor, and then controlling the rotation of the second screw rod 91, and then controlling the movement of the second nut 93, and then controlling the movement of the detection member clamped on the clamp 30, and then can control the blocking member 50 of different thicknesses to move to the blocking position according to the demand, that is, the control platform can control the proximity switch detection fixture 100, so that the proximity switch detection fixture 100 completes the detection of the proximity switch. Since the position of the proximity switch installed on the base 10 is known, that is, the position of the installation station 10a is known, when the detection member clamped on the clamp 30 moves on the base 10, the control platform can calculate the distance between the proximity switch and the detection member according to the moving distance of the detection member. With such a configuration, the control platform can be remotely and automatically controlled so that the proximity switch detection fixture 100 completes the detection of the proximity switch, thereby simplifying the operation steps, and further facilitating the detection of the proximity switch and improving the test efficiency.
