Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical equipment technology, and in particular to a guide rail testing device and method. Background Technology
[0002] In the inspection of guide rails in ordinary products, the object of inspection is the track gauge of guide rails installed face-to-face. That is, the distribution of track gauge along the length of the guide rail is obtained by measurement. Usually, an inductive micrometer or laser rangefinder is used as the main sensing device, combined with simple support fixtures, to complete the track gauge inspection. However, the object of inspection involved in this invention is the built-in guide rail of a miniaturized device.
[0003] After the product was miniaturized, the testing space was reduced, making it impossible to use the aforementioned sensitive devices and tooling to collect the characteristics of the guide rail. In addition, the parameters to be tested are not only the track gauge, but also other geometric parameters such as the straightness of the guide rail.
[0004] Faced with reduced detection space and increased measured parameters, commonly used measuring equipment, such as inductive micrometers or laser rangefinders, and tooling, cannot be used.
[0005] To detect the gauge and additional parameters of the built-in guide rails in miniaturized products, considering the testing conditions, the most suitable measuring equipment is a laser tracking measurement system. However, when using a laser tracking measurement system, it is necessary to adjust the red-ring reflector, such as... Figure 9 The reflectors were placed sequentially at different positions on the surface of the guide rail being tested, with the measurement positions covering the entire guide rail surface. Due to the long length of the guide rail and the confined space for testing, it was impossible to stably place the red-ring reflectors at each measurement position on the guide rail without specialized tools. Consequently, the necessary conditions for data acquisition by the laser tracking measurement system could not be met, leading to measurement failure.
[0006] Therefore, it is necessary to develop a dedicated testing device to measure various parameters of the guide rail under test. Summary of the Invention
[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple and easy-to-operate mechanical structure. More importantly, the provided mechanical structure can stably clamp the red ring reflector of the laser tracking measurement system as described above, and can ensure that the red ring reflector is always in contact with the guide rail under test during the measurement process, thus ensuring that the necessary conditions for data acquisition using the laser tracking measurement system are met, thereby completing the acquisition of the characteristic data of the guide rail under test and realizing the detection of parameters.

[0022] In some embodiments, the L-shaped bracket 4 is connected to the guide rail support 9 by screw six 23, and the lower component 5 is connected to the L-shaped bracket 4 by screw one 3.
[0023] This invention provides a guide rail detection method, based on the guide rail detection device described in any of the above embodiments, comprising the following steps:
[0024] Step 1: Collect data on the geometric features of the upper guide rail surface, and remove the lower component 5, L-shaped bracket 4, screw 1 3 and screw 6 23;

[0036] The beneficial effects of the above embodiments include:
[0037] The detection device designed in this invention features a simple structure, convenient installation, and compact size, enabling precise measurement of the built-in guide rail characteristics of miniaturized products using a laser tracking measurement system. In this invention, the spherical countersunk hole of the spherical mirror pressure plate is height-adapted to the outer spherical surface of the red-ring reflector, improving the clamping stability of the red-ring reflector. Simultaneously, a circular hole at the upper end of the spherical mirror pressure plate fully exposes the outer surface of the red-ring reflector. These features meet the necessary conditions for laser tracking measurement, thereby ensuring the accuracy of the detection.
[0038] In this invention, the suction cup holder is made of aluminum alloy, effectively reducing the weight of the detection device and facilitating the detection process. The inner wall of the flared opening at the upper end of the suction cup holder is fully adapted to the outer spherical surface of the red ring reflector, ensuring stable clamping. A permanent magnet is built into the suction cup holder, with a designed installation distance of 0.5mm between the magnet and the red ring reflector. This ensures that the magnet does not contact the surface of the red ring reflector while still firmly adsorbing it, thus enhancing the stability of the red ring reflector installation and demonstrating superior positioning accuracy. Furthermore, the use of the magnet simplifies the disassembly and reuse of the red ring reflector, improving the practicality of this device.
[0039] In this invention, the fit between the outer cylindrical surface of the suction cup holder and the inner hole of the upper / lower sleeve adopts the hole basis system H9 / d9, which can effectively avoid improper gap between the outer cylindrical surface of the suction cup holder and the inner hole of the upper / lower sleeve, ensuring that the suction cup holder can be compressed into the upper / lower sleeve without obstruction or shaking during the test, further ensuring measurement stability.
[0040] In this invention, support blocks are installed on both sides of the suction cup base. During testing, the support blocks move with the suction cup base into the U-shaped grooves of the upper / lower sleeves. The cooperation between the support blocks and the U-shaped grooves of the upper / lower sleeves helps to limit the rotational jitter of the suction cup base during the measurement process, thereby improving the positioning stability of the red-ring reflector.
[0041] In this invention, the orientation of the upper component is manually adjusted via a transition sleeve, and the height of the upper component is manually adjusted via a height adjustment bracket. These adjustable mechanisms improve the convenience of the testing process and make the testing operation more convenient.
[0042] In this invention, the upper and lower components have essentially the same structure and component parameters, resulting in excellent interchangeability. The upper and lower components can be installed simultaneously or separately without affecting measurement results or data acquisition, facilitating operation.
[0043] In summary, this invention is suitable for the inspection of built-in guide rails in miniaturized products, and is convenient to operate and provides a stable measurement process. It solves the following problems: existing technologies and testing conditions cannot achieve the inspection of built-in guide rails in miniaturized products; currently, when using laser tracking measurement systems, measurement failures occur because the red-ring reflector cannot maintain stable contact with the surface of the guide rail being measured.

[0060] The detection device designed in this invention has a simple structure, is easy to install, and is compact in size. It can achieve accurate measurement of the built-in guide rail features of miniaturized products using a laser tracking measurement system. This invention includes a red-ring reflector and a target. In this invention, the spherical countersunk hole of the spherical mirror pressure plate can be adapted to the height of the outer spherical surface of the red-ring reflector, improving the clamping stability of the red-ring reflector; at the same time, a circular hole is provided at the upper end of the spherical mirror pressure plate, fully exposing the outer surface of the red-ring reflector. This meets the necessary conditions for laser tracking measurement, thereby ensuring the accuracy of the detection.
[0061] In this invention, the suction cup holder is made of aluminum alloy, effectively reducing the weight of the detection device and facilitating the detection process. The inner wall of the flared opening at the upper end of the suction cup holder is fully adapted to the outer spherical surface of the red ring reflector, ensuring stable clamping. A permanent magnet is built into the suction cup holder, with a designed installation distance of 0.5mm between the magnet and the red ring reflector. This ensures that the magnet does not contact the surface of the red ring reflector while still firmly adsorbing it, thus enhancing the stability of the red ring reflector installation and demonstrating superior positioning accuracy. Furthermore, the use of the magnet simplifies the disassembly and reuse of the red ring reflector, improving the practicality of this device.
[0062] In this invention, the fit between the outer cylindrical surface of the suction cup holder and the inner hole of the upper / lower sleeve adopts the hole basis system H9 / d9, which can effectively avoid improper gap between the outer cylindrical surface of the suction cup holder and the inner hole of the upper / lower sleeve, ensuring that the suction cup holder can be compressed into the upper / lower sleeve without obstruction or shaking during the test, further ensuring measurement stability.
[0063] In this invention, support blocks are installed on both sides of the suction cup base. During testing, the support blocks move with the suction cup base into the U-shaped grooves of the upper / lower sleeves. The cooperation between the support blocks and the U-shaped grooves of the upper / lower sleeves helps to limit the rotational jitter of the suction cup base during the measurement process, thereby improving the positioning stability of the red-ring reflector.
[0064] In this invention, the orientation of the upper component is manually adjusted via a transition sleeve, and the height of the upper component is manually adjusted via a height adjustment bracket. These adjustable mechanisms improve the convenience of the testing process and make the testing operation more convenient.
[0065] In this invention, the upper and lower components have essentially the same structure and component parameters, resulting in excellent interchangeability. The upper and lower components can be installed simultaneously or separately without affecting measurement results or data acquisition, facilitating operation.
[0066] In summary, this invention is suitable for the inspection of built-in guide rails in miniaturized products, and is convenient to operate and provides a stable measurement process. It solves the following problems: existing technologies and testing conditions cannot achieve the inspection of built-in guide rails in miniaturized products; currently, when using laser tracking measurement systems, measurement failures occur because the red-ring reflector cannot maintain stable contact with the surface of the guide rail being measured.
[0067] The following is in conjunction with the appendix Figures 1 to 10 The guide rail detection device and method of the present invention will be described in detail.
[0068] like Figure 1 The guide rail testing device shown includes an upper component 1, a transition sleeve 2, an L-shaped bracket 4, a lower component 5, a height adjustment bracket 7, a lifting eye screw 8, and a guide rail support 9.
[0069] As described above, in the complete structure of the detection device, the upper component 1 consists of... Figures 5-7 As shown. The upper component 1 mainly includes: a red-circle reflector 12, a suction cup seat 13, an upper sleeve 14, a spherical mirror pressure plate 15, a pressure plate bracket 17, and a support block 19.
[0070] The red-circled reflector 12 in the upper component 1 is made of Figure 9 As shown, the overall shape is a standard sphere, with a flared structure serving as a light-receiving window for receiving laser signals. This component is a standard configuration of laser tracking measurement systems and is a crucial device for performing inspection operations using such systems. The structure of the suction cup holder 13 in the upper component 1 is as follows... Figure 10 As shown, a permanent magnet 22 is installed in the suction cup holder 13.
[0071] As described above, in the complete structure of the detection device, the structure and composition of the lower component 5 are almost identical to those of the upper component 1, with the only difference being that the upper sleeve 14 in the upper component 1 is replaced by the lower sleeve 21 in the lower component 5. Figure 8 The upper and lower sleeves are identical in structure, except for slight differences in size; the lifting spring 10 in the upper component 1, such as Figure 3 Replace the lower component 5 with the lower compression spring 11, such as Figure 3The lifting spring 10 and the compression spring 11 have the same structural features except for their size. The remaining structures and components of the lower component 5 and the upper component 1 are completely identical, which improves the interchangeability and reusability of the main components in this invention.
[0072] As described above, since the structural features of the lower component 5 and the upper component 1 are highly consistent, the following description will mainly focus on the upper component 1 as an example to specifically describe its features and the implementation of the present invention.
[0073] As mentioned above, the guide rails under test are arranged face-to-face, parallel, and in pairs. For ease of description, the paired guide rails are defined as the upper guide rail and the lower guide rail based on their position in the product.
[0074] When using a laser tracking measurement system to measure a guide rail, data can only be collected sequentially and separately from the surface features of the upper and lower guide rails. Taking the upper guide rail as an example, when measuring the upper guide rail, the outer surface of the red-ring reflector 12 must always be in contact with the surface of the guide rail being measured. However, the surface of the upper guide rail being measured faces downwards, pointing towards the ground. Due to gravity, the red-ring reflector 12 cannot obtain effective support and therefore cannot stably adhere to the track being measured throughout the measurement process.
[0075] The main function of this invention is to securely clamp the red ring reflector 12 and ensure that the outer spherical surface of the red ring reflector 12 is always in contact with the surface of the guide rail being measured during measurement.
[0076] Furthermore, in component 1 of this invention, the red ring reflector 12 is clamped and mounted on the suction cup seat 13 via a spherical mirror clamping plate 15 and a clamping plate bracket 17. The two clamping plate brackets 17 are rigidly connected to the spherical mirror clamping plate 15 via screws 16. The spherical mirror clamping plate 15 has a spherical countersunk hole inside that matches the height of the outer spherical surface of the red ring reflector 12, ensuring the stability of the red ring reflector 12 during installation. On the left and right sides of the spherical mirror clamping plate 15, clamping plate brackets 17 are symmetrically installed, closely adhering to the outer spherical surface of the red ring reflector 12, providing clamping and positioning in the horizontal direction, further restricting the degree of freedom of the red ring reflector 12. The top of the spherical mirror clamping plate 15 has a circular opening. After the red ring reflector 12 is installed in place, part of the outer spherical surface of the red ring reflector 12 will be exposed through this circular opening, and the exposed surface will be in contact with the surface of the guide rail being measured, enabling data acquisition.
[0077] Furthermore, such as Figure 10The red-ring reflector 12 is mounted on the suction cup base 13, fitting snugly against the flared transition surface of the upper end of the suction cup base 13. Simultaneously, to enhance the installation stability of the red-ring reflector 12, a permanent magnet 22 is installed at the bottom of the stepped hole at the upper end of the suction cup base 13. Preferably, after the permanent magnet 22 is mounted on the suction cup base 13, the gap between the upper surface of the permanent magnet 22 and the red-ring reflector 12 is approximately 0.5mm. This ensures that the red-ring reflector 12 receives sufficient magnetic force to be stably attracted to the suction cup base 13, while also avoiding direct contact between the permanent magnet 22 and the red-ring reflector 12, thus mitigating the potential risk of surface damage to the red-ring reflector 12 caused by direct contact.
[0078] Furthermore, two support blocks 19 are symmetrically installed on the left and right sides of the suction cup base 13 in the upper component 1. One mounting surface of the support block 19 is rigidly connected to the suction cup base 13 by screw 20. The other mounting surface of the support block 19 is rigidly connected to the pressure plate bracket 17 by screw 18. In this way, the full degree of freedom of the red ring reflector 12 is restricted, which plays a role in clamping and stabilizing it.
[0079] Furthermore, in this invention, a lifting spring 10 is installed at the lower end of the suction cup seat 13 in the upper component 1. The lifting spring 10 is specially designed and manufactured so that when the detection device performs detection on the upper guide rail, the lifting spring 10 can provide appropriate elastic force, so that the red circle reflector 12 can always be attached to the surface of the guide rail being tested, and the related structure will not be damaged due to excessive elastic force.
[0080] Furthermore, the other end of the lifting spring 10 in the upper component 1 is connected to the inner hole of the upper sleeve 14 by adhesive. The installation stability of the lifting spring 10 can be ensured by the preferred adhesive.
[0081] When measuring the upper guide rail, the red-ring reflector 12 contacts the surface of the upper guide rail being measured, and the suction cup seat 13 and its upper structure are compressed, causing the lifting spring 10 to compress. At this time, the arc-shaped mounting surface of the support block 19 moves into the U-shaped grooves on both sides of the upper sleeve 14. The limiting function of the U-shaped grooves eliminates the rotational wobbling of the red-ring reflector 12 during measurement, ensuring measurement stability. On the other hand, when the lifting spring 10 is compressed, the suction cup seat 13 moves into the upper sleeve 14. There is a fitting clearance between the outer diameter of the suction cup seat 13 and the aperture of the upper sleeve 14. If the clearance is too large, the red-ring reflector 12 will shift in the pitch direction during measurement, affecting the quality of laser signal reception and hindering measurement implementation; if the clearance is too small, the suction cup seat 13 cannot smoothly sink into the upper sleeve 14, causing jamming during sinking, affecting the accuracy of the measurement implementation and results. To avoid the aforementioned problems, after design calculations and verification, the adopted technical measures are to design the inner surface of the upper sleeve 14 and the outer surface of the suction cup seat 13 with a roughness of 1.6 and a fitting accuracy of H9 / d9. This will ensure optimal operating conditions.
[0082] In this invention, the upper sleeve 14 of the upper component 1 is inserted into the transition sleeve 2. The outer diameter of the upper sleeve 14 is clearance-fitted with the bore diameter of the transition sleeve 2, and is positioned and connected by screws 6. This connection method provides the upper component 1 with a convenient opportunity for orientation adjustment, improves the assembly error tolerance of this invention, and also takes into account the ease of operation, thus possessing high engineering practical value.
[0083] Furthermore, the drive end of the height adjustment bracket 7 is connected via a screw hole at the bottom of the transition sleeve 2. The height adjustment bracket 7 is an externally purchased component, model GCM-0104M. Height adjustment can be achieved manually.
[0084] Furthermore, the bottom fixed end of the height adjustment bracket 7 is threadedly connected to the guide rail support 9. The guide rail support 9 is the base of this invention and is installed on the lower guide rail. The bottom of the guide rail support 9 has a U-shaped groove structure, with the bottom surface of the groove fitting against the surface of the lower guide rail, and the groove width slightly larger than the width of the lower guide rail. The advantage of the U-shaped groove structure is that, through reasonable design, it can ensure the matching of the guide rail support 9 and the lower guide rail in shape, and the limiting function of the U-shaped groove ensures that the guide rail support 9 will not slip off the lower guide rail when the detection device moves along the guide rail, thus ensuring the smoothness of the detection process.
[0085] In this invention, the L-shaped bracket 4 is secured by screw six 23, as shown. Figure 3 It is connected to the guide rail support 9. The lower component 5 is connected to the L-shaped bracket 4 by screw 3. The lower component 5 will be used when data on the geometric features of the lower guide rail is required. As mentioned above, the relevant features of the lower component 5 are highly consistent with those of the upper component 1, and will not be described again.
[0086] In this invention, the eye bolt 8 is installed at the tail of the guide rail support 9. It is used to pull the testing device during testing.
[0087] An embodiment of the guide rail detection method of the present invention is as follows.
[0088] It should be noted that, as mentioned earlier, the guide rails under test are installed face-to-face in pairs, generally consisting of an upper guide rail and a lower guide rail. Testing the guide rails requires data acquisition for each of the upper and lower guide rails individually. Using this invention, the method for testing the guide rails, including the upper and lower guide rails, is as follows:
[0089] Step one: If the upper guide rail is to be inspected first, data on the geometric features of the upper guide rail surface should be collected. At this point, for ease of operation, the lower component 5, the L-shaped bracket 4, along with screw 3 and screw 23, can be removed from the overall structure of this invention. The removal process is very simple, requiring only the removal of two screws, 23.
[0090] Step two: Operate the device according to the user manual of the laser tracking measurement system. The operation process is not within the scope of this invention and will not be described. When the laser tracking measurement system is in working condition, remove the upper component 1 from the transition sleeve 2. Hold the upper component 1 and align the light-collecting window of the red-circle reflector 12 in the upper component 1 with the light source emitted by the laser tracking measurement system, so that the laser tracking measurement system receives a signal and is in tracking mode;
[0091] Step 3: Slowly move the upper component 1 into the transition sleeve 2 so that the laser tracking measurement system is still in the tracking state. Do not tighten screw 26 at this time.
[0092] Step four: Slowly place the entire structure, including upper component 1, transition sleeve 2, height adjustment bracket 7, eye bolt 8, and guide rail support 9, near the guide rail being measured. During this process, the laser tracking measurement system remains in tracking mode.
[0093] Step 5: Place the overall structure described in Step 4 stably onto the guide rail to be tested. First, compress the red-ring reflector 12 in the upper component 1, causing the suction cup seat 13 and above to move down into the upper sleeve 14. Simultaneously, place the guide rail support 9 onto the lower guide rail, positioning the lower guide rail within the grooved structure at the bottom of the guide rail support 9. Then, slowly release the compressive force of the upper component 1, allowing the outer surface of the red-ring reflector 12 to adhere to the surface of the upper guide rail to be tested. During this process, ensure the operation is slow and that the laser tracking measurement system remains in tracking mode as much as possible.
[0094] Step 6: Attach a length-marked traction rope to eye bolt 8 and extend it from the end of the guide rail being measured.
[0095] Step 7: Manually rotate and adjust the orientation of upper component 1 to its optimal position, ensuring there are no obstructions outside the light-receiving window in the red-circled reflector 12, thus not affecting laser reception. At this point, tighten screw 26.
[0096] Step eight: The installation preparation work for the detection device of this invention is completed. Following the instructions for use of the laser tracking measurement system, complete the feature data acquisition of the upper guide rail surface. During the measurement process, manually and slowly pull the traction rope marked with length to move the detection device on the guide rail being measured. When it reaches the detection position, stop pulling the traction rope and operate the laser tracking measurement system to perform the necessary data acquisition. Then pull the traction rope again to drag the detection device to the next measurement position until all data acquisition is completed. The detection device is then removed from the end of the guide rail. At this point, the feature data acquisition of the upper guide rail is complete, and the measurement is finished.
[0097] Step nine, measure the lower guide rail. Remove the upper component 1 from the transition sleeve 2. Then, install the lower component 5 and the L-shaped bracket 4, including screw 3 and screw 23, into the guide rail support 9.
[0098] Step 10: Lift the detection device assembled in Step 9 and align the light-collecting window of the red circle reflector 12 with the laser tracking measurement system to put it into tracking mode.
