Description

Technical Field

[0001] This utility model relates to the technical field of measuring instruments, and in particular to a universal integrated guide displacement sensor. Background Technology

[0002] In modern industrial production, precision manufacturing, engineering monitoring, automation control, and many other fields, displacement sensors, as core devices for accurately measuring changes in object position, are increasingly widely used, and the requirements for their measurement performance are constantly improving. Whether it's the precise inspection of workpiece dimensions in machine tool processing, the real-time monitoring of mechanical component displacement in production lines, or the long-term tracking of structural deformation in bridge construction monitoring, displacement sensors provide crucial data support for the stable operation and precise control of various systems.

[0003] However, existing displacement sensors have the following shortcomings in practical use: the measuring rods of existing displacement sensors are generally fixed in place, and their length is fixed after manufacturing, making it impossible to adjust them according to actual usage requirements. In actual industrial applications, different working conditions have significantly different requirements for the range of displacement. When faced with different measurement range requirements, it is impossible to adapt to new working conditions by adjusting the length of the existing sensor's measuring rod; one must choose to replace it with a sensor model with a corresponding measuring length. To meet the measurement needs of different working conditions, it is often necessary to purchase multiple sensor models with different measuring lengths, which directly leads to a significant increase in equipment procurement costs. In view of this, the universal integrated guide displacement sensor proposed in this application is proposed. Utility Model Content

[0032] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0033] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0036] like Figures 1 to 9As shown, in one embodiment, a universal integrated guide displacement sensor 1 includes a base 10 and a measuring component. The measuring component includes a measuring rod 20, a guide member 21, an elastic member 22, and several rolling rings 23. The guide member 21 is detachably mounted on the base 10. One end of the measuring rod 20 passes through the guide member 21, and the other end of the measuring rod 20 passes through the base 10 without contact. Each rolling ring 23 is rotatably mounted on the base 10, and each rolling ring 23 rolls against the outer side wall of the measuring rod 20. Both ends of the elastic member 22 abut against the base 10 and the measuring rod 20, respectively. The elastic member 22 pushes the measuring rod 20 to extend relative to the guide member 21, so that each rolling ring 23 rolls along the outer side wall of the measuring rod 20.

[0037] It should be noted that the guide member 21 is detachably mounted on the base 10. One end of the measuring rod 20 is coaxially inserted through the guide member 21, while the other end of the measuring rod 20 passes through the base 10 without contact. Each rolling ring 23 is rotatably mounted on the base 10, and each rolling ring 23 rolls against the outer walls of the measuring rod 20, so that the rolling rings 23 together clamp the end of the measuring rod 20 away from the guide member 21. Thus, both ends of the measuring rod 20 are supported by the rolling rings 23 and the guide member 21. It should be noted that the rolling rings 23 together clamp the measuring rod 20 and allow the measuring rod 20 to slide coaxially relative to the guide member 21. Furthermore, the elastic member 22 is a spring structure, with both ends abutting against the middle positions of the base 10 and the measuring rod 20, respectively. When the elastic member 22 pushes the end of the measuring rod 20 away from the base 10 to extend relative to the guide member 21, the rolling rings 23 can roll against the outer walls of the measuring rod 20. This means that each rolling ring 23 clamps the measuring rod 20 to support it, while also restricting its movement so that it can only slide along the axis of the guide member 21. Furthermore, one end of the measuring rod 20 rolls against each rolling ring 23, and the other end of the measuring rod 20 passes coaxially through the guide member 21, one end of which is detachably mounted on a base 10. When the guide member 21 is removed from the base 10, the measuring rod 20 can slide out from the base 10. Thus, under different operating conditions, the guide member 21 can be disassembled to replace the measuring rod 20 with different lengths to obtain displacement sensors with different ranges. This allows for quick changes in the length of the measuring rod 20 in practical industrial applications to meet the measurement needs of different operating conditions, thereby reducing equipment procurement costs.

[0038] like Figure 6 , Figure 8 As shown, in one embodiment, the measuring rod 20 is provided with a circular portion 201 and a square portion 202. The circular portion 201 passes through the guide member 21, and the square portion 202 passes through the base 10 without contact. Each rolling ring 23 rolls against the outer side wall around the square portion 202.

[0039] It should be noted that the measuring rod 20 is integrally formed with a circular portion 201 and a square portion 202, making the measuring rod 20 an irregularly shaped rod structure. Furthermore, the circular portion 201 is coaxially inserted through the guide member 21, with the end of the circular portion 201 away from the square portion 202 extending from the end of the guide member 21 away from the base 10. The square portion 202 passes through the base 10 without contact and extends from the end of the base 10 away from the guide member 21. In one embodiment, the square portion 202 has a rectangular cross-section, such that the square portion 202 is centered on the axis of the circular portion 201, with its four sides respectively... Four sides are formed; each rolling ring 23 rolls against the four sides of the square part 202 to clamp the measuring rod 20 together. When the elastic member 22 drives the circular part 201 to extend from the end of the guide member 21 away from the base 10, it simultaneously drives the square part 202 to move closer to the guide member 21. During the process of the square part 202 sliding closer to the guide member 21, since each rolling ring 23 rolls against the four sides of the square part 202, each rolling ring 23 can restrict the square part 202 in four directions to prevent the square part 202 from deviating and make it slide only along the axial direction of the guide member 21.

[0040] It should be noted that under long-term, high-frequency use, each rolling ring 23 rolls against the square part 202, which reduces the metal friction between the square part 202 and each rolling ring 23 during the sliding process, thereby reducing the wear of the square part 202 and reducing the aggravation of wear. However, the aggravation of wear will cause the gap of the originally precise fit to gradually increase, which will affect the guiding constraint ability and cause the measuring rod 20 to deviate during the sliding process.

[0041] like Figure 3 , Figures 5 to 6 As shown, in one embodiment, a retaining ring 203 is provided on the measuring rod 20, and the two ends of the elastic member 22 abut against the base 10 and the retaining ring 203 respectively.

[0042] It should be noted that the length of the long side of the cross-section of the square part 202 is greater than the diameter of the circular part 201, so that the connection between the circular part 201 and the square part 202 forms a stepped structure; the retaining ring 203 is coaxially fitted onto the circular part 201 and close to the square part 202, so that a circumferentially protruding locking platform is formed on the measuring rod 20; the two ends of the elastic member 22 abut against the base 10 and the retaining ring 203 respectively, so that the elastic member 22 can push the retaining ring 203 to drive the circular part 201 to extend from the end of the guide member 21 away from the base 10; similarly, when the end of the circular part 201 extending from the guide member 21 abuts against the object being measured, the circular part 201 will squeeze the elastic member 22 through the retaining ring 203 to complete the contraction. In this way, under the continuous pushing of the elastic force of the elastic member 22, the retaining ring 203 can drive the circular part 201 to maintain the extended state so that it can quickly abut against the object being measured.

[0043] It should be noted that the measuring rod 20 is also provided with a retaining ring 204. The circular part 201 has an annular groove 2010. The inner diameter of the retaining ring 204 is the same as the diameter of the annular groove 2010, and the outer diameter of the retaining ring 204 is larger than the diameter of the circular part 201. The annular groove 2010 is located at the end of the circular part 201 near the square part 202. The retaining ring 204 is coaxially engaged with the annular groove 2010. In this way, the stepped structure formed at the connection position of the circular part 201 and the square part 202 and the retaining ring 204 can jointly clamp the retaining ring 203, so as to prevent the retaining ring 203 from sliding from the end of the circular part 201 near the square part 202 to the other end when the elastic member 22 pushes the retaining ring 203, thereby preventing the elastic member 22 from driving the measuring rod 20 to slide.

[0044] like Figure 5 , Figure 9 As shown, in one embodiment, a retaining ring 203 is provided with a retaining groove 2030, and the end of the elastic member 22 away from the base 10 abuts against the inner bottom wall of the retaining groove 2030.

[0045] It should be noted that the retaining ring 203 has an annular groove 2030 on the side near the square portion 202, and the minimum diameter of the groove 2030 is greater than the length of the long side of the cross-section of the square portion 202. The base 10 has a limiting platform 101 on the end face near the guide member 21, through which the square portion 202 passes without contact. The elastic member 22 has a minimum diameter greater than the length of the long side of the cross-section of the square portion 202. One end of the elastic member 22 is fitted with the limiting platform 101, and the other end of the elastic member 22 is coaxially abutted against the inner bottom wall of the groove 2030. This ensures that when the elastic member 22 is coaxially fitted onto the square portion 202, it is fitted onto the square portion 202 without contact. This prevents friction between the elastic member 22 and the square portion 202 during compression or sliding, thus avoiding affecting the accuracy of the sliding of the square portion 202.

[0046] like Figures 3 to 5 As shown, in one embodiment, the guide member 21 includes a sleeve 210 and an end block 211. The sleeve 210 is detachably disposed on the base 10, and the end block 211 is disposed on the end of the sleeve 210 away from the base 10. The circular portion 201 is coaxially disposed on the end block 211.

[0047] It should be noted that one end of the sleeve 210 is screwed onto the bottom surface of the base 10, allowing the guide 21 to be disassembled / installed relative to the base 10. The end block 211 is also screwed onto the end of the sleeve 210 away from the base 10. The guide 21 also includes a guide sleeve 212 and a pressure block 213. For example, the guide sleeve 212 is a guide wear-resistant sleeve structure. The end block 211 has a circular hole, and the guide sleeve 212 is coaxially disposed in the circular hole. The outer diameter of the circular part 201 is... The inner diameter of the guide sleeve 212 is adapted; the pressure block 213 is a ring structure, and the pressure block 213 is coaxially screwed onto the end block 211 so that the pressure block 213 and the end block 211 together clamp the guide sleeve 212. The circular part 201 passes through the pressure block 213, the guide sleeve 212 and the end block 211 coaxially in sequence, and there is a slight gap between the pressure block 213 and the end block 211 and the circular part, so that the circular part 201 can slide coaxially inside the guide sleeve 212; thus, the sliding accuracy and stability of the measuring rod 20 are improved.

[0048] It should be noted that since the two ends of the sleeve 210 are screwed to the base 10 and the end block 211 respectively, when it is necessary to replace the measuring rod 20 of different lengths, the measuring rod 20 can be removed from the base 10 after the sleeve 210 is unscrewed from the base 10 and the end block 211. In this way, by simply replacing the matching measuring rod 20 and sleeve 210, displacement sensors with different ranges can be obtained, thereby greatly reducing the equipment procurement cost.

[0049] like Figure 3 , Figure 5 As shown, in one embodiment, the inner diameter of the sleeve 210 is the same as the outer diameter of the retaining ring 203.

[0050] It should be noted that the outer diameter of the retaining ring 203 is the same as the inner diameter of the sleeve 210, so that when the circular part 201 abuts against the object being measured to compress the elastic element 22, the circular part 201 simultaneously drives the retaining ring 203 to slide coaxially within the sleeve 210; specifically, when the circular part 201 drives the retaining ring 203 to slide to the end of the sleeve 210 near the base 10, the end block 211, the retaining ring 203 and each rolling ring 23 support the two ends and the middle position of the measuring rod 20 on an axis, thereby improving the stability and accuracy of the sliding of the measuring rod 20.

[0051] like Figures 1 to 4 , Figure 7 As shown, in one embodiment, the base 10 has a through hole 103 and a groove 102, which are connected in a cross shape, and the square portion 202 passes through the through hole 103 without contact.

[0052] It should be noted that the base 10 has a through hole 103, with both ends of the through hole 103 penetrating through the upper and lower ends of the base 10 respectively. The through hole 103 is coaxially connected to the sleeve 210, and the diameter of the through hole 103 is larger than the length of the long side of the cross-section of the square part 202, allowing the square part 202 to pass through the through hole 103 without contact. The base 10 also has a groove 102, which is opened from one side of the base 10 inward, and the groove 102 is connected to the through hole 103 in a cross shape. When the square part 202 passes through the through hole 103, the square part 202 can also pass through the groove 102. This is equivalent to creating a visual window on the base 10 that allows the square part 202 to slide.

[0053] like Figures 1 to 4 , Figure 6 As shown, in one embodiment, the measuring component further includes a sensing strip 24 and a circuit board 25. The sensing strip 24 is disposed on the measuring rod 20, and the circuit board 25 is disposed on the base 10. One end of the circuit board 25 extends into the groove 102 so that the circuit board 25 and the sensing strip 24 are parallel to each other and do not directly contact each other.

[0054] It should be noted that the sensing strip 24 is a strip-shaped structure. The sensing strip 24 is disposed on the side of the square portion 202 away from the bottom wall of the groove 102, and the sensing strip 24 extends from one end of the square portion 202 to the other end to cover the entire length of the square portion 202. This allows the square portion 202 to slide through the through hole 103, and the square portion 202 simultaneously drives the sensing strip 24 to pass through the through hole 103 without contact. Furthermore, the width of the sensing strip 24 is smaller than the width of the square portion 202. Two of the rolling rings 23 roll and abut against the side of the square portion 202 closest to the sensing strip 24, and are located on both sides of the sensing strip 24. In this way, when the rolling rings 23 roll relative to the square portion 202, the rolling rings 23 will not crush the sensing strip 24. Furthermore, one end of the circuit board 25 is disposed on the base 10, and the other end of the circuit board 25 extends into the groove 102. The circuit board 25 and the sensing strip 24 are parallel to each other and do not directly contact each other. When the square part 202 drives the sensing strip 24 through the through hole 103, the sensing components on the circuit board 25 can capture the movement data of the sensing strip 24.

[0055] like Figure 1 , Figures 3 to 4 As shown, in one embodiment, the universal integrated guide displacement sensor 1 further includes a housing 30 and a face cover 40. The base 10 and the measuring components are all disposed inside the housing 30. The sleeve 210 passes through the housing 30 and is connected to the base 10. The face cover 40 is disposed in a sealed manner on the housing 30.

[0056] It should be noted that the housing 30 has a through hole 301, the base 10 is disposed inside the housing 30, and the sleeve 210 passes through the through hole 301 and is connected to the base 10; a sealing groove 3010 for installing a sealing ring is provided on the inner side wall of the through hole 301, so that when the sleeve 210 passes through the through hole 301 and is connected to the base 10, the sealing ring can seal the gap between the sleeve 210 and the housing 30.

[0057] like Figures 1 to 3 As shown, in one embodiment, the measuring assembly further includes a protective tube 50, which is detachably mounted on the base 10 and is coaxially arranged with the sleeve 210.

[0058] It should be noted that the housing 30 also has a screw hole, which is located on the end of the housing 30 away from the sleeve 210, and the screw hole is coaxially aligned with the through hole 301. The protective tube 50 is a tubular structure with one end closed. The unclosed end of the protective tube 50 is screwed into the screw hole, so that the protective tube 50 is coaxially aligned with the sleeve 210. When the circular part 201 abuts against the object being measured to compress the elastic element 22, the circular part 201 drives the square part 202 to pass through the base 10 and extend into the protective tube 50. In this way, when the measuring rod 20 measures a shorter distance, part of the square part 202 can be accommodated in the protective tube 50, thereby increasing the measurable range of the measuring rod 20 and further improving the adaptability of the displacement sensor under different working conditions. Furthermore, the inner diameter of the protective tube 50 is larger than the length of the long side of the cross-section of the square part 202, so that the square part 202 extends into the protective tube 50 without contact, thereby improving the accuracy of the sliding of the measuring rod 20.

[0059] It should be noted that when a longer measuring rod 20 is replaced, a longer protective tube 50 can be disassembled and replaced to meet the depth requirements of the square part 202. In this way, to meet the measurement needs of different working conditions, displacement sensors with different ranges can be obtained by replacing the protective tube 50, the sleeve 210, and the measuring rod 20, avoiding the need to purchase multiple sensors with different ranges separately, thereby reducing the procurement cost of the equipment.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
