Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment, and in particular to a guide rail detection device and method. Background Art

[0002] In the guide rail inspection of ordinary products, the object of inspection is the gauge of the guide rails installed face to face. That is, the distribution of the gauge in the length direction of the guide rail is obtained by measurement. Usually, an inductive micrometer or a laser rangefinder is used as the main sensitive device, combined with a simple supporting tooling to complete the gauge inspection. However, the object to be measured involved in the present invention is a built-in guide rail of a certain miniaturized device.

[0003] After the product is miniaturized, the detection space is compressed, and the above-mentioned sensitive devices and tooling cannot be used to collect the characteristics of the guide rail. In addition, the parameters to be detected are not only the gauge, but also other geometric parameters such as the straightness of the guide rail.

[0004] Faced with the reduction of detection space and the increase of measured parameters, the commonly used measuring equipment in the past, such as inductive micrometers or laser rangefinders, and tooling cannot be used.

[0005] In order to detect the gauge and additional parameters of the built-in guide rails of miniaturized products, the most suitable measuring equipment is the laser tracking measurement system in combination with the testing conditions. However, when using the laser tracking measurement system, the red circle reflector, such as Fig. 9 , and placed in different positions on the surface of the measured rail in turn, and the measurement positions need to cover the entire rail surface. Since the measured rail is long and the space for detection is narrow, it is impossible to stably place the red circle reflector on each measurement position of the rail without special tools. Therefore, the necessary conditions for data acquisition by the laser tracking measurement system cannot be met, resulting in measurement failure.

[0006] Therefore, it is necessary to develop a special detection device to measure the parameters of the guide rail being tested. Summary of the invention

[0007] The purpose of the present invention is to provide a mechanical structure with simple structure and easy operation in view of the shortcomings of the prior art; more importantly, the provided mechanical structure can stably clamp the red circle reflector of the laser tracking and measurement system as described above, and can keep the red circle reflector in contact with the measured guide rail at all times during the measurement process, thereby ensuring that the necessary conditions for using the laser tracking and measurement system for data collection are met, thereby completing the characteristic data collection of the measured guide rail and realizing parameter detection.

It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0060] The detection device designed by the present invention has a simple structure, is easy to install, and is compact, and can realize the accurate measurement of the built-in guide rail features of miniaturized products by the laser tracking measurement system. In the present invention, the red circle reflector and the target. In the present invention, the spherical countersunk hole of the spherical mirror pressure plate can be highly adapted to the outer spherical surface of the red circle reflector, thereby improving the clamping stability of the red circle reflector; at the same time, a circular hole is provided at the upper end of the spherical mirror pressure plate, so that the outer surface of the red circle reflector is fully exposed. The necessary conditions for laser tracking measurement are met, thereby ensuring the accuracy of the detection.

[0061] In the present invention, the suction cup seat is made of aluminum alloy, which effectively reduces the weight of the detection device and facilitates the implementation of the detection process. The inner wall of the horn mouth of the upper port of the suction cup seat is fully adapted to the outer spherical surface of the red circle reflector to ensure stable clamping; the suction cup seat has a built-in permanent magnet, and the magnet and the red circle reflector are designed to be installed at a distance of 0.5mm, which ensures that the magnet will not contact the surface of the red circle reflector, and can firmly adsorb the red circle reflector, thereby enhancing the installation stability of the red circle reflector and showing excellent positioning. In addition, the use of magnets makes the disassembly and reuse of the red circle reflector simple, which improves the practicality of the device.

[0062] In the present invention, the cooperation between the outer cylindrical surface of the suction cup seat and the inner hole of the upper / lower sleeve adopts the basic hole system H9 / d9, which can effectively avoid the improper gap between the outer cylindrical surface of the suction cup seat and the inner hole of the upper / lower sleeve, and ensure that when the detection is carried out, the suction cup seat can be compressed into the upper / lower sleeve without obstruction and shaking, thereby further ensuring the measurement stability.

[0063] In the present invention, support blocks are installed on both sides of the suction cup seat. During detection, the support blocks will move with the suction cup seat into the U-shaped groove of the upper / lower sleeve. The support blocks cooperate with the U-shaped groove of the upper / lower sleeve, which is conducive to limiting the rotational jitter of the suction cup seat during the measurement process and improving the positioning stability of the red circle reflector.

[0064] In the present invention, the position of the upper component is manually adjusted by the transition sleeve, and the height of the upper component is manually adjusted by the height adjustment bracket. These adjustable mechanisms can improve the convenience of detection implementation and make the detection operation more convenient.

[0065] In the present invention, the structural form and part parameters of the upper / lower components are basically the same, and the interchangeability is excellent. The upper / lower components can be installed simultaneously or separately, which will not affect the measurement results and data collection, and is easy to operate.

[0066] In summary, the present invention is suitable for the detection of built-in guide rails of miniaturized products, and is easy to operate and has a stable measurement process. The following problems are solved: the existing technology and detection conditions cannot realize the detection of built-in guide rails of miniaturized products; currently, when using a laser tracking measurement system, the red circle reflector cannot stably contact the surface of the measured guide rail, resulting in measurement failure.

[0067] The following is combined with Figures 1 to 10 The guide rail detection device and method according to the embodiment of the present invention are described in detail.

[0068] like Figure 1 The guide rail detection 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 mentioned above, in the complete structure of the detection device, the structure of the upper component 1 is composed of Figure 5 to Figure 7 The upper assembly 1 mainly includes: a red circle reflector 12, a suction cup seat 13, an upper sleeve 14, a ball mirror pressure plate 15, a pressure plate bracket 17, and a support block 19.

[0070] The red circle reflector 12 in the upper component 1 is composed of Fig. 9 As shown, the whole is in a standard spherical shape, and the trumpet-shaped structure is a lighting window for receiving laser signals. This part is a standard configuration of the laser tracking measurement system and is an important component for implementing inspection operations using the laser tracking measurement system. The structure of the suction cup seat 13 in the upper component 1 is as shown in FIG. Fig.10 As shown, a permanent magnet 22 mounted in a suction cup seat 13 is shown.

[0071] As described above, in the complete structure of the detection device, the structure and composition of the lower component 5 are almost completely consistent with the upper component 1, and the only difference from the upper component 1 is 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 / lower sleeves have the same structural features except for slightly different sizes; the lifting spring 10 in the upper component 1, such as Figure 3 , replaced with a downward pressure spring 11 in the lower component 5, such as Figure 3The lifting spring 10 and the pressing spring 11 have the same structural features except for the different sizes. The remaining structures and parts of the lower assembly 5 and the upper assembly 1 are completely the same, which improves the interchangeability and reusability of the main parts in the present invention.

[0072] As described above, since the structural features of the lower component 5 and the upper component 1 are highly consistent, the following mainly takes the upper component 1 as an example to specifically describe its features and the implementation methods of the present invention.

[0073] As mentioned above, the guide rails to be tested are face-to-face, parallel, and arranged in pairs. For the convenience of description, the guide rails arranged in pairs are defined as upper guide rails and lower guide rails according to their positions in the product.

[0074] When using a laser tracking measurement system to measure the guide rail, data can only be collected for the surface features of the upper / lower guide rails in sequence and separately. Taking the upper guide rail as an example, when it is necessary to measure the upper guide rail, the outer surface of the red circle reflector 12 needs to always be in contact with the measured guide rail surface. However, the measured surface of the upper guide rail faces downward, pointing to the ground. Affected by gravity, the red circle reflector 12 cannot obtain effective support, and therefore cannot always stably fit the measured track during the measurement process.

[0075] The main function of the present invention is to firmly clamp the red circle reflector 12 and to ensure that the outer spherical surface of the red circle reflector 12 is always in contact with the measured guide rail surface during measurement.

[0076] Furthermore, in the upper component 1 of the present invention, the red circle reflector 12 is clamped and installed on the suction cup seat 13 through the spherical mirror pressure plate 15 and the pressure plate bracket 17. The two pressure plate brackets 17 are rigidly connected to the spherical mirror pressure plate 15 through screws 16. The interior of the spherical mirror pressure plate 15 is provided with a spherical countersunk hole that is highly adapted to the outer spherical surface of the red circle reflector 12, ensuring the installation stability of the red circle reflector 12; the pressure plate brackets 17 are symmetrically installed on the left and right sides of the spherical mirror pressure plate 15, close to the outer spherical surface of the red circle reflector 12, playing a clamping and positioning role in the horizontal direction, further limiting the freedom of the red circle reflector 12. There is a circular opening on the top of the spherical mirror pressure plate 15. After the red circle reflector 12 is installed in place, part of the outer spherical surface of the red circle reflector 12 will be exposed through the circular hole, and the exposed surface will fit with the measured guide rail surface to achieve data collection.

[0077] Further, if Fig.10, the red circle reflector 12 is installed on the suction cup seat 13, and fits with the flared transition surface of the upper end surface of the suction cup seat 13. At the same time, in order to enhance the installation stability of the red circle reflector 12, a permanent magnet 22 is installed at the bottom of the stepped hole at the upper end of the suction cup seat 13. Preferably, after the permanent magnet 22 is installed on the suction cup seat 13, it can be ensured that the gap between the upper surface of the permanent magnet 22 and the red circle reflector 12 is about 0.5 mm. In this way, it is ensured that the red circle reflector 12 can obtain sufficient magnetic force so that it can be stably adsorbed on the suction cup seat 13, and it can also avoid direct contact between the permanent magnet 22 and the red circle reflector 12, thereby avoiding the potential risk of surface damage to the red circle reflector 12 caused by direct contact.

[0078] Furthermore, two support blocks 19 are symmetrically mounted on the left and right sides of the suction cup seat 13 in the upper assembly 1. One mounting surface of the support block 19 is rigidly connected to the suction cup seat 13 by screws 5 20. The other mounting surface of the support block 19 is rigidly connected to the pressure plate bracket 17 by screws 4 18. In this way, the full degree of freedom of the red circle reflector 12 is restricted, and the clamping is stable.

[0079] Furthermore, in the present invention, a lifting spring 10 is installed at the lower end of the suction cup seat 13 in the upper assembly 1. The lifting spring 10 is specially designed and manufactured. When the detection device implements the detection of the upper guide rail, the lifting spring 10 can provide a suitable elastic force, so that the red circle reflector 12 can always be attached to the surface of the guide rail to be detected, and the related structure will not be damaged due to excessive elastic force.

[0080] Further, the other end of the lifting spring 10 in the upper assembly 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 circle reflector 12 contacts the measured upper guide rail surface, the suction cup seat 13 and the structure above it will be compressed, and the lifting spring 10 will be compressed. At this time, the arc mounting surface of the support block 19 will move to the U-shaped grooves on both sides of the upper sleeve 14. The limiting function of the U-shaped groove eliminates the rotation and shaking of the red circle reflector 12 during the measurement process, ensuring the stability of the measurement. On the other hand, when the lifting spring 10 is compressed, the suction cup seat 13 will move into the upper sleeve 14. There is a matching gap between the outer diameter of the contour of the suction cup seat 13 and the aperture of the upper sleeve 14. If the gap is too large, the red circle reflector 12 will be offset in the pitch direction during the measurement process, affecting the quality of laser signal reception and being unfavorable for measurement implementation; if the gap is too small, the suction cup seat 13 cannot be smoothly sunk into the upper sleeve 14, causing jamming during sinking, affecting the measurement implementation and the accuracy of the measurement results. In order to avoid the above problems, after design calculation and verification, the technical means adopted are to design the inner hole surface of the upper sleeve 14 and the outer surface of the suction cup seat 13 to have a roughness of 1.6 and a matching accuracy of H9 / d9, so as to obtain the best use conditions.

[0082] In the present invention, the upper sleeve 14 in the upper assembly 1 is installed in the transition sleeve 2. The outer diameter of the upper sleeve 14 is clearance-matched with the aperture of the transition sleeve 2, and is positioned and connected by screws 6. This connection method provides a convenient orientation adjustment opportunity for the upper assembly 1, improves the assembly fault tolerance rate of the present invention, and takes into account the convenience of operation, and has a high engineering practical value.

[0083] Further, the driving end of the height adjustment bracket 7 is connected through the screw hole at the bottom of the transition sleeve 2. The height adjustment bracket 7 is an outsourced part, model GCM-0104M. The height can be adjusted 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 the present invention, which is installed on the lower guide rail. The bottom of the guide rail support 9 is a U-shaped groove structure, the bottom surface of the groove is in contact with the surface of the lower guide rail, and the groove width is slightly larger than the width of the lower guide rail. The advantage of the U-shaped groove structure is that the guide rail support 9 and the lower guide rail can be matched in appearance through reasonable design, and the limiting function of the U-shaped groove prevents the guide rail support 9 from sliding off the lower guide rail when the detection device is translated along the guide rail, thereby ensuring the smoothness of the detection process.

[0085] In the present invention, the L-shaped bracket 4 is provided with screws 23, such as Figure 3 , connected to the guide rail support 9. The lower component 5 is connected to the L-shaped bracket 4 by screws 3. If the geometric features of the lower guide rail need to be quantified, the lower component 5 will be used. 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 repeated.

[0086] In the present invention, the eye screw 8 is installed at the tail of the guide rail support 9 to pull the detection device during detection.

[0087] An embodiment of a guide rail detection method of the present invention is as follows.

[0088] It should be noted that, as mentioned above, the guide rails to be tested are installed face to face and in pairs, and are generally divided into upper guide rails and lower guide rails. The detection of the guide rails requires data collection for the upper / lower guide rails one by one. Using the present invention, the method for implementing the detection of the guide rails to be tested, including the upper guide rail and the lower guide rail, is as follows:

[0089] Step 1: If the upper rail is detected first, data collection of the geometric features of the upper rail surface is performed first. At this time, for ease of operation, the lower component 5, the L-shaped bracket 4, together with the screw 1 3 and the screw 6 23 can be removed from the overall structure of the present invention. The removal process is very simple, and only two screws 6 23 need to be removed.

[0090] Step 2: Operate the laser tracking measurement system according to the instructions for use. The operation process is not within the scope of the present invention and will not be described. When the laser tracking measurement system is in operation, remove the upper component 1 from the transition sleeve 2. Hold the upper component 1, and align the light window of the red circle reflector 12 in the upper component 1 with the light source of the laser tracking measurement system, so that the laser tracking measurement system obtains a signal and is in a tracking state;

[0091] Step 3, slowly move the upper assembly 1 into the transition sleeve 2, so that the laser tracking measurement system is still in the tracking state, and do not tighten the screw 2 6 at this time;

[0092] Step 4: slowly place the entire structure of the upper assembly 1, transition sleeve 2, height adjustment bracket 7, eyebolt 8 and guide rail support 9 near the guide rail to be measured. During this process, the laser tracking measurement system is still kept in the tracking state.

[0093] Step five, place the overall structure described in step four stably on the guide rail to be measured. First, compress the red circle reflector 12 in the upper component 1 to move the suction cup seat 13 and the above structure down to the inside of the upper sleeve 14. At the same time, place the guide rail support 9 on the lower guide rail so that the lower guide rail is in the groove structure at the bottom of the guide rail support 9. Then, slowly relax the compression force of the upper component 1 so that the outer surface of the red circle reflector 12 fits the surface of the upper guide rail to be measured. During this period, pay attention to slow operation and try to ensure that the laser tracking measurement system is in tracking state;

[0094] Step 6: Tie a traction rope with a length mark on the eye screw 8 and lead it out from the end of the guide rail to be measured.

[0095] Step 7: Manually rotate and adjust the position of the upper assembly 1 to make it in the best position, that is, there is no obstruction outside the lighting window in the red circle reflector 12, which does not affect the reception of the laser. At this time, tighten the screw 2 6.

[0096] Step eight, the installation preparation work of the detection device of the present invention is completed. Subsequently, according to the instructions for use of the laser tracking measurement system, complete the feature data collection of the upper guide rail surface. During the measurement process, manually and slowly pull the traction rope with a length mark to move the detection device on the guide rail to be measured. When it moves to the detection position, stop pulling the traction rope, operate the laser tracking measurement system, and perform necessary data collection. Then pull the traction rope again to drag the detection device to the next measurement position until all data collection is completed. The detection device moves out from the end of the guide rail. At this point, the feature data collection of the upper guide rail is completed and the measurement is completed.

[0097] Step 9, measuring the lower rail. Remove the upper assembly 1 from the transition sleeve 2. Then, install the lower assembly 5, the L-shaped bracket 4, including the screw 1 3 and the screw 6 23, into the rail support 9.
