Description

Technical Field

[0001] This invention belongs to the field of testing, and in particular relates to a portable device for testing the perpendicularity of the mounting surface of a slide table lead screw nut. Background Technology

[0002] Before installing the lead screw and nut, the verticality of the mounting surface used to hold the nut needs to be checked. Ensuring that the mounting surface is vertical is essential for the smooth installation of the nut and lead screw. Insufficient accuracy or tilting can lead to issues such as wear and tear on the teeth.

[0003] However, in practice, there are no effective testing methods or measuring tools available; the only option is to use a coordinate measuring machine (CMM). But CMM testing has the following problems:

[0004] 1. Slide tables are generally made of castings and are quite large, ranging from 40 kg to several hundred kg. This makes them difficult to handle and can also damage the coordinate measuring machine due to their excessive weight.

[0005] 2. The detection efficiency is relatively low, and it is not possible to measure multiple points simultaneously.

[0006] 3. The test data is not intuitive and cannot directly generate an intuitive verticality test data table; it requires a professional to understand.

[0007] For example, a Chinese invention patent discloses a device for measuring the perpendicularity of a nut thread hole [application number CN202020418515.4], which includes a positioning shaft, a measuring arm, a large dial indicator, and a small dial indicator. The positioning shaft, the large dial indicator, and the small dial indicator are mounted on the measuring arm, with the two dial indicators located on opposite sides of the positioning shaft. This device effectively solves the problem of measuring the perpendicularity of the thread hole to the contact surface of the nut, and can also be used to measure the perpendicularity of thread holes on a plane. Summary of the Invention

[0008] The purpose of this invention is to address the above-mentioned problems by providing a portable device for detecting the perpendicularity of the mounting surface of a slide table lead screw nut.

[0009] To achieve the above objectives, the present invention adopts the following technical solutions:

[0010] A portable sliding table screw nut mounting surface perpendicularity detection device includes a base, a reference platform on the base, a mounting seat on the reference platform, a mounting surface on the mounting seat, and first reference surfaces on both sides of the reference platform. A portable detection device is slidably connected to the upper shell of the base. The portable detection device is in contact with at least one of the first reference surfaces and can move closer to or away from the mounting surface along the first reference surface. The portable detection device includes several unidirectional, parallel, and flush distance sensing detectors.

[0011] In the aforementioned portable sliding table screw nut mounting surface perpendicularity detection device, the portable detection device further includes a cross frame, several distance sensor detectors are fixed on the cross frame, and vertical frames are respectively provided at both ends of the cross frame. The vertical frames are located outside the mounting base and at least one vertical frame is in contact with the first reference surface.

[0012] In the aforementioned portable sliding table screw nut mounting surface perpendicularity detection device, a sliding table body is provided on both sides of the mounting base, and a second reference surface is provided on the sliding table body. The second reference surface is located on the lower side of the mounting base, and one end of the second reference surface is connected to the first reference surface. At least one vertical frame is simultaneously in contact with both the second reference surface and the first reference surface.

[0013] In the aforementioned portable slide table lead screw nut mounting surface perpendicularity detection device, the first reference surface and the second reference surface are set perpendicularly, and the first reference surface is perpendicular to the upper surface of the reference platform.

[0014] In the aforementioned portable slide table lead screw nut mounting surface verticality detection device, a sliding groove is provided between the first reference surface and the second reference surface, and the vertical frame may be provided with a limiting slider that is slidably connected to the sliding groove.

[0015] In the aforementioned portable slide table screw nut mounting surface verticality detection device, a support plate can be placed on the inner side of the bottom of the vertical frame. The support plate is cuboid and fits against the vertical frame.

[0016] In the aforementioned portable sliding table screw nut mounting surface perpendicularity detection device, the portable detection device is further provided with a stop ball, which can abut against the mounting surface. The stop ball is flush with the distance sensor detector or the stop ball is closer to the mounting surface than the distance sensor detector.

[0017] In the aforementioned portable slide table screw nut mounting surface perpendicularity detection device, the abutment ball is screwed to the portable detection device by a bolt, and a nut is screwed onto the bolt. The nut locks the bolt by abutting against the portable detection device.

[0018] In the aforementioned portable slide table lead screw nut mounting surface perpendicularity detection device, each distance sensor detector has two positioning holes provided on the portable detection device, and the positioning holes penetrate the portable detection device.

[0019] In the aforementioned portable slide table lead screw nut mounting surface perpendicularity detection device, the portable detection device is connected to a linear slow-moving force structure, and the distance sensor detector is connected to the background processor via a wire.

[0020] Compared with existing technologies, the advantages of this invention are:

[0021] 1. This detection method is relatively portable and can measure multiple points simultaneously, resulting in high detection efficiency. In addition, the detection data is presented in digital form, which is more intuitive and easy for ordinary people to understand.

[0022] 2. You can select one of the vertical supports to attach to the corresponding first reference surface and move along it for detection. To ensure accuracy, you can also continue to use another vertical support to attach to the corresponding first reference surface and move along it for repeated detection.

[0023] 3. By restricting the movement direction of the vertical frame from two directions, it is further ensured that the movement direction of the portable testing device is specified and does not deviate, thus ensuring the accuracy and effectiveness of the testing results.

[0024] 4. During use, to prevent the bolts from loosening, the bolts are locked by screwing the nuts into the bolts and pressing them against the portable detection device. Attached Figure Description

[0025] Figure 1 This is a schematic diagram of the structure of the present invention;

[0026] Figure 2 This is a diagram from another direction.

[0027] In the figure: base 10, reference platform 11, mounting base 12, mounting surface 13, first reference surface 14, portable detection device 15, distance sensor detector 16, horizontal frame 17, vertical frame 18, slide body 19, second reference surface 20, sliding groove 21, bearing plate 22, abutment ball 23, bolt 24, nut 25, positioning hole 26. Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-2 As shown, a portable sliding table screw nut mounting surface perpendicularity detection device includes a base 10, a reference platform 11 on the base 10, a mounting seat 12 on the reference platform 11, a mounting surface 13 on the mounting seat 12, and first reference surfaces 14 on both sides of the reference platform 11. A portable detection device 15 is slidably connected to the upper shell of the base 10. The portable detection device 15 is in contact with at least one of the first reference surfaces 14 and can move closer to or away from the mounting surface 13 along the first reference surface 14. The portable detection device 15 includes a plurality of unidirectional, parallel and flush distance sensing detectors 16.

[0030] In this embodiment, during the detection of the perpendicularity of the mounting surface 13, the portable detection device 15 slowly moves and brings the distance sensor detector 16 close to the mounting surface 13. During the movement, the portable detection device 15 stays close to the first reference surface 14. The direction of movement of the portable detection device 15 is specified and does not deviate, ensuring the accuracy and effectiveness of the detection results. The distance sensor detector 16 records the movement values ​​as it approaches. When the distance sensor detector 16 moves to the specified position, the distance between the detection head of each distance sensor detector 16 and the mounting surface 13 is clearly recorded. Several distance sensors 16 are aligned with different points on the mounting surface 13. If the data are the same and there is no error when compared with the detection data of the standard part, it indicates that the mounting surface 13 is not tilted or bent and meets the perpendicularity accuracy requirements. This detection method is portable and can measure multiple points simultaneously, resulting in high detection efficiency. Furthermore, the detection data is presented in digital form, which is intuitive and easy for ordinary people to understand.

[0031] The portable detection device 15 also includes a cross frame 17, and several distance sensing detectors 16 are fixed on the cross frame 17. Vertical frames 18 are provided at both ends of the cross frame 17. The vertical frames 18 are located outside the mounting base 12 and at least one vertical frame 18 is in contact with the first reference surface 14.

[0032] In this embodiment, the vertical frame 18 is used to support the weight of the horizontal frame 17 and the distance sensor 16 on the horizontal frame 17. On the other hand, there are two vertical frames 18. During the detection process, one of the vertical frames 18 can be selected to be attached to the corresponding first reference surface 14 and moved along it for detection. In order to ensure accuracy, the other vertical frame 18 can also be used to be attached to the corresponding first reference surface 14 and moved along it for repeated detection.

[0033] The mounting base 12 is provided with slide bodies 19 on both sides. The slide body 19 is provided with a second reference surface 20. The second reference surface 20 is located on the lower side of the mounting base 12. One end of the second reference surface 20 is connected to the first reference surface 14. At least one vertical bracket 18 is in contact with both the second reference surface 20 and the first reference surface 14.

[0034] In this embodiment, during the movement of the vertical frame 18, it simultaneously contacts and moves with the first reference surface 14 and the second reference surface 20, restricting the movement direction of the vertical frame 18 from two directions. This further ensures that the movement direction of the portable detection device 15 is specified and does not deviate, thus ensuring the accuracy and effectiveness of the detection results.

[0035] The first reference surface 14 is perpendicular to the second reference surface 20, and the first reference surface 14 is perpendicular to the upper surface of the reference platform 11.

[0036] In this embodiment, the perpendicular setting of the first reference surface 14 and the second reference surface 20 is predetermined. What needs to be measured is the vertical accuracy of the mounting surface 13, which requires the mounting surface 13 to be perpendicular to both the first reference surface 14 and the second reference surface 20 to meet the vertical accuracy requirement. The first reference surface 14 and the second reference surface 20 not only serve as guides but also as reference surfaces for detecting whether the mounting surface 13 meets the verticality accuracy requirement.

[0037] Preferably, a sliding groove 21 is provided between the first reference surface 14 and the second reference surface 20, and the vertical frame 18 may be provided with a limiting slider that is slidably connected to the sliding groove 21.

[0038] In this embodiment, the limiting slider can extend into the sliding groove 21. The direction of the sliding groove 21 is unique, which is used to ensure that the moving direction of the portable detection device 15 is specified and does not deviate, thus ensuring the accuracy and effectiveness of the detection results.

[0039] Preferably, a support piece 22 can be placed on the inner side of the bottom of the vertical frame 18. The support piece 22 is cuboid and fits against the vertical frame 18.

[0040] In this embodiment, a support piece 22 can be added to reduce friction and wear between the vertical frame 18 and the first reference surface 14, thereby increasing its service life and the accuracy of detection, while ensuring that the moving direction does not deviate.

[0041] The portable detection device 15 is also provided with a contact ball 23, which can abut against the mounting surface 13. The contact ball 23 is flush with the distance sensor detector 16 or the contact ball 23 is closer to the mounting surface 13 than the distance sensor detector 16.

[0042] In this embodiment, the abutment ball 23 is used to protect the probe part of the distance sensor detector 16. The abutment ball 23 and the probe of the distance sensor detector 16 abut against the mounting surface 13 at the same time, or the abutment ball 23 abuts against the mounting surface 13. At this time, the distance sensor detector 16 still leaves a gap with the mounting surface 13 to prevent the impact from damaging the probe of the distance sensor 16.

[0043] The abutment ball 23 is screwed to the portable detection device 15 by bolt 24. A nut 25 is also screwed onto the bolt 24. The nut 25 locks the bolt 24 by abutting against the portable detection device 15.

[0044] In this embodiment, the abutment ball 23 is fixed by screwing the bolt 24 into the portable detection device 15. During use, to prevent the bolt 24 from loosening, the bolt 24 is locked by screwing the nut 25 into the bolt 24 and abutting against the portable detection device 15.

[0045] Each distance sensor detector 16 corresponds to two positioning holes 26 provided on the portable detection device 15, and the positioning holes 26 penetrate the portable detection device 15.

[0046] In this embodiment, when installing the distance sensor detector 16, the positioning hole 26 is used to position the distance sensor 16 and lock it with the positioning rod inserted, and also serves to prevent displacement during use.

[0047] The portable detection device 15 is connected to a linear slow-moving force structure, and the distance sensor detector 16 is connected to the background processor via a wire.

[0048] In this embodiment, during the detection process, the data generated by the distance sensor detector 16 is transmitted to the processor for recording and analysis, which can intuitively tell the inspection personnel whether it is qualified.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0050] Although this document frequently uses terms such as base 10, reference platform 11, mounting base 12, mounting surface 13, first reference surface 14, portable detection device 15, distance sensor detector 16, horizontal frame 17, vertical frame 18, slide body 19, second reference surface 20, sliding groove 21, bearing plate 22, abutment ball 23, bolt 24, nut 25, and positioning hole 26, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention.
