Description

Technical Field

[0002] Linear guides are machines used to support and guide moving parts so that they can move linearly in a given direction. Usually, a slider is moved on the guide rail, and other objects are fixed on the slider, so that the slider can drive the objects to move linearly. They are widely used in various production equipment. However, since the slider and the guide rail are in direct contact, a certain amount of friction will be generated between the two during the sliding process of the slider. Long-term use can easily cause wear of the guide rail, resulting in reduced motion accuracy and stability of the linear guide, which brings risks to the normal operation of related equipment.

[0003] In order to ensure the normal operation of production equipment, it is necessary to regularly inspect the guide rails for wear, so that the degree of wear of the guide rails can be discovered in time, so that corresponding maintenance measures can be taken to ensure that the equipment is always in good working condition and to ensure the smooth progress of production; however, traditional wear detection usually relies on manual inspection, and inspectors judge the wear of the guide rails by visual observation and using simple measuring tools, which is easily affected by human factors, resulting in deviations in the test results, causing erroneous judgments and reducing the reliability of the test; at the same time, manual inspection is relatively inefficient, and requires a lot of time and energy, which increases labor costs.

[0014] A wear detection method for a wear detection device for a linear guide rail comprises the following steps: Step 1: Preparation; Check the status of each component of the device, move the guide rail body to the device, connect the device to the external power supply, and prepare for wear detection operation; Step 2: Fix the guide rail; The guide rail body is placed between two groups of baffles, and one group of the baffles is contacted first. The rotating motors at both ends of the fixed crossbar in the fixing assembly are operated, and the moving gear is driven to rotate by the rotating motor. The moving gear is meshed with the moving rack, and the fixed crossbar moves along the slide bar; through the movement of the fixed crossbar, the other group of baffles is driven to move toward the guide rail body, and move to contact with the guide rail body. At the same time, the power-on seat is energized, and the internal electromagnet generates magnetic attraction, and the guide rail body is adsorbed thereon, and the guide rail is fixed; Step 3: spraying of magnesium fluoride coating; After the guide rail body is fixed, the controller controls the two groups of screw slides to operate, and moves the entire fixed component, and the fixed component drives the guide rail body to move; the guide rail body moves to below the detection component and the spray component, the screw slide stops running, and the electric cylinder in the spray component retracts and extends, driving the spray pipe to move downward, so that the spray pipe is located between the two groups of baffles; the infusion pump starts to run, and transports the magnesium fluoride liquid from the liquid storage tank to the spray pipe, and then sprays it evenly on the upper surface of the guide rail body through the nozzle arranged on the spray pipe; the fan starts to run, and the airflow enters the air outlet through the air duct, and blows to the surface of the guide rail body through the air outlet to accelerate the drying of the coating; at the same time, the spray assembly moves linearly on the detection base through the slide rail structure, and sprays the magnesium fluoride coating on the entire guide rail body; Step 4: Wear detection; The controller issues a command to make the electric slider slide on the slide rail of the detection frame, driving the detection component to move, and the visual recognition module recognizes that the recognition block stops moving; the laser transmitter is turned on, and the laser emitted by the laser transmitter passes through the beam splitter to form two groups of lasers, one of which is directed to the surface of the guide rail body and reflected, and the other is irradiated to the reflective plate and then reflected back. The two laser beams are reunited at the beam splitter and received by the detector; the detector converts the received optical signal into an electrical signal and transmits it to the connector, and the connector transmits the signal to the controller; the controller transmits the received signal to the processor for analysis and processing, and determines whether the guide rail body is worn and the degree of wear according to the processing results; after the detection is completed, the electric slider continues to move until it moves to the next group of recognition blocks and restarts the above detection steps; Step 5: Recording of test results and subsequent processing; The processor transmits the final detection result to the controller, and the controller records and stores the detection result. When it is detected that the wear degree of the guide rail body exceeds the set threshold, it is necessary to take measures such as repair or replacement in time; when the wear degree is within the normal range, the guide rail body can continue to be used normally; Step 6: Return components to their original positions; After the detection is completed, the controller issues an instruction again, the electric slider slides in the opposite direction, driving the detection component back to the initial position, and the spray component is also restored to its original position through the slide rail structure; the two groups of the screw slides operate to move the fixed component outward, the power-on seat is powered off, and the adsorption of the guide rail body is released. At the same time, the rotating motor rotates in the opposite direction, the fixed cross bar moves outward, the distance between the two groups of the baffles is expanded, the fixation of the guide rail body is released, and the guide rail body is removed to facilitate the next detection of the guide rail body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The laser emitter, beam splitter, detector and other components in the detection component work together to perform wear detection based on optical principles and optical interferometry. The laser emitted by the laser emitter forms a specific optical path after passing through the beam splitter, interacts with the surface of the guide rail body and the reflector, and finally the detector receives the reflected light and converts it into an electrical signal for analysis. It can measure the microscopic wear of the guide rail surface and detect smaller-scale wear changes, greatly improving the detection accuracy. At the same time, the electric slider slides on the slide rail of the detection frame to drive the detection component to move, and the visual recognition module identifies the identification block on the fixed bottom plate to determine the detection position. The entire process realizes automated positioning and detection operations, avoiding detection deviations caused by the instability and subjectivity of human operations in manual detection, improving the accuracy and reliability of the detection results, and improving the detection efficiency. During the wear detection process, the detection component can move on the guide rail body according to a certain pattern and repeat the detection steps. The electric slider can drive the detection component to move along the length of the guide rail, so as to detect different positions of the guide rail body, ensuring a comprehensive assessment of the wear condition of the entire guide rail surface, which helps to more accurately judge the overall wear condition of the guide rail and promptly discover possible local severe wear areas.

[0016] 2. The fixing assembly adopts a combination of multiple components to fix the guide rail body. Through the coordinated work of the fixed crossbar, the moving rack, the moving gear, the rotating motor, the baffle and the energized seat, the guide rail body can be clamped between the two sets of baffles, and the magnetic attraction of the electromagnet in the energized seat is used to further enhance the fixing effect, ensuring that the guide rail body will not be displaced during the detection process, providing a stable basis for wear detection. Compared with the shaking or instability of the guide rail during traditional manual detection, the accuracy of the detection results is greatly improved. At the same time, the structure of the fixing assembly gives it good flexibility and adaptability. The fixed crossbar and the fixed base plate are slidably connected by a sliding rod, and the fixed plate on the fixed crossbar is detachable, which enables the fixing assembly to adapt to linear guides of different sizes. Whether it is a narrower or wider guide rail, it can be firmly fixed by adjusting the position of the fixed crossbar and the installation of the fixed plate, which improves the versatility of the detection device and reduces the detection error that may be caused by the difference in the size of the guide rail.

[0017] 3. The spraying assembly can spray magnesium fluoride coating on the surface of the guide rail body. During the detection process, since magnesium fluoride has a high reflectivity, the spraying of the coating helps to improve the reflection effect of the laser on the surface of the guide rail, thereby enhancing the quality of the detection signal, so that the detector can receive the reflected light signal more accurately, thereby improving the accuracy of wear detection. The electric cylinder in the spraying assembly can be retracted to drive the spraying tube to move, and the infusion pump can evenly transport the magnesium fluoride liquid in the storage tank to the spraying tube and spray it on the surface of the guide rail body. It ensures that the coating can be evenly covered on the surface of the guide rail to avoid the situation where the local coating is too thick or too thin. At the same time, during the spraying process, the spraying assembly can also move linearly on the detection base through the slide rail structure, and can perform efficient spraying operations on the entire guide rail body, ensuring the consistency of the entire guide rail surface, which helps to improve the stability of the detection results. The spraying assembly is also equipped with a fan and an air outlet. After the spraying is completed, the fan can quickly send the airflow into the air outlet through the air duct, and then blow it to the surface of the guide rail body to accelerate the drying of the coating. The fast-drying coating enables the subsequent wear detection operation to be carried out in a timely manner, avoiding interference with the test results due to the coating not being dry, improving the efficiency of the entire detection process and ensuring that the detection work can be carried out continuously and efficiently.

[0018] 4. The reinforcement bracket is connected to the detection base through positioning bolts, which provides a high degree of stability for the entire device. The positioning through holes on the reinforcement bracket match the multiple groups of positioning holes on the detection base, so that the positioning bolts can fix the relative position of the two. The height of the reinforcement bracket can be adjusted according to the use requirements, effectively preventing the detection base from shaking or displacement during operation. When the pad is connected to the two groups of reinforcement brackets to form a work surface, the work surface provides operators with a place to place items such as tables for recording and writing. In the process of detecting linear guide wear, operators need to record various data, such as detection time, detection position, wear amount and other parameters. With this work surface, they can easily record in real time at the detection site, avoiding distractions due to finding a suitable recording location or causing untimely and inaccurate data recording. Operators also do not need to leave the detection device to find other recording locations, which saves time and improves the efficiency of the entire detection process.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0022] Embodiment 1: Figures 1 to 13As shown, the present invention provides a wear detection device for a linear guide rail, including a detection base 101 and a guide rail body 21. The detection base 101 serves as the basic support structure of the entire detection device. A fixing component is arranged on the detection base 101, and the fixing component plays a role in firmly fixing the guide rail body 21 during the entire detection process. Among them, the fixing component includes a fixed base plate 301, which is the basic component in the fixed component and provides a reference surface for the installation and coordinated work of other related components. Two groups of screw slides 102 are installed on the detection base 101, and the fixed base plate 301 is connected to the two groups of screw slides 102, so that the fixed base plate 301 can move under the drive of the screw slide 102, thereby adjusting the position of the guide rail body 21 fixed thereon to meet different detection requirements or facilitate various operations during the detection process. The detection base 101 is also provided with a detection frame 103, on which two sets of slide rails 22 are installed, and the slide rails 22 are slidably provided with an electric slider 23, which is a component that can slide smoothly on the slide rails 22 under electric drive. A detection component is arranged above the detection base 101, which is responsible for detecting the wear of the guide rail body 21. The detection component includes a mounting seat 401 and a laser emitter 402. The mounting seat 401 provides a mounting position for the laser emitter 402, and the mounting seat 401 is connected to the two sets of electric sliders 23, so that the mounting seat 401 can move as the electric slider 23 slides on the slide rails 22, thereby driving the laser emitter 402 to reach different positions of the guide rail body 21 for detection. The laser emitter 402 is installed on the mounting seat 401 and can emit a laser beam. The laser emitter 402 can use an OSRAM PLT5230 laser emitter. The detection base 101 is provided with a processor 24 and a controller 25. The processor 24 is mainly responsible for processing and analyzing the data obtained during the detection process, such as performing complex calculations and analysis on the data fed back after the laser emitted by the laser emitter 402 interacts with the guide rail body 21, so as to obtain an accurate conclusion about the wear of the guide rail body 21. The processor 24 can adopt the Texas Instruments (TI) TMS320F28335 processor. The controller 25 plays a role in controlling and coordinating the various components of the entire detection device, such as controlling the sliding speed and direction of the electric slider 23, controlling the movement of the screw slide 102, etc. The controller 25 can adopt the Arduino Mega 2560 controller. A spraying component is also provided above the detection base 101. The spraying component can perform surface treatment and other related operations on the guide rail body 21 before detection. The entire device is connected to an external power supply to realize power supply to all components.

[0023] As 2, Figure 7As shown, two groups of fixed brackets 302 are arranged above the fixed base plate 301, and the fixed brackets 302 are detachably connected to the fixed base plate 301 through multiple groups of fixing bolts. During the installation process, the operator can tighten the fixing bolts to ensure that the fixed brackets 302 are installed on the fixed base plate 301; and when it is necessary to perform equipment maintenance or adjust the device, the fixing bolts can be easily removed to remove the fixed brackets 302 for corresponding operations. A fixed crossbar 303 is arranged above the fixed base plate 301, and multiple groups of sliding bars 304 are arranged on the fixed base plate 301. The fixed crossbar 303 has through holes corresponding to the sliding bars 304, and the sliding bars 304 are inserted into the through holes, thereby realizing the slidable connection between the fixed crossbar 303 and the fixed base plate 301, so that the fixed crossbar 303 can move relative to the fixed base plate 301, providing the necessary conditions for the subsequent fixing operation of the guide rail bodies 21 of different sizes. Two groups of fixing plates 305 are detachably provided on the fixed cross bar 303. Baffle plates 306 are installed on one side of the two groups of fixing plates 305 and the two groups of fixing brackets 302. The baffle plates 306 are components directly used to fix the guide rail body 21. The guide rail body 21 is clamped between the two groups of baffle plates 306 to ensure that the guide rail body 21 maintains a stable position during the detection process; at the same time, when the spray assembly is running, it also plays a barrier role to prevent the spray liquid from splashing everywhere.

[0024] The fixed assembly also includes two groups of mobile racks 307 and two groups of mobile gears 308. The two groups of mobile racks 307 are respectively installed at the two ends of the fixed base plate 301. A fixed frame 309 is provided at both ends of the fixed crossbar 303. The mobile gear 308 is located in the fixed frame 309, and two groups of bearings are provided on the fixed frame 309. The two ends of the mobile gear 308 are respectively penetrated in the bearings, so that the mobile gear 308 can rotate freely in the fixed frame 309. The mobile gear 308 is meshed with the mobile rack 307, and this meshing relationship constitutes an effective transmission mechanism. A rotating motor 310 is installed on one side of the fixed frame 309, and the shaft end of the rotating motor 310 is connected to the mobile gear 308. When the rotating motor 310 is started, the shaft end of the rotating motor 310 drives the mobile gear 308 to rotate. Due to the meshing action of the mobile gear 308 and the mobile rack 307, the rotation of the mobile gear 308 will be converted into a linear motion of the fixed crossbar 303 along the slide bar 304. In this way, the movement of the fixed crossbar 303 can be controlled, and the distance between the two groups of baffles 306 can be adjusted to adapt to the guide rail bodies 21 of different widths. A plurality of fixed grooves 311 are provided on the fixed bottom plate 301, and a power-on seat 312 is provided in the fixed groove 311, and an electromagnet is provided in the power-on seat 312. When the guide rail body 21 is clamped between the two groups of baffles 306, the power-on seat 312 is energized, and the internal electromagnet generates a magnetic attraction. This magnetic attraction can further enhance the fixing effect of the guide rail body 21, prevent the guide rail body 21 from being slightly displaced during the detection process, thereby providing a more reliable guarantee for the accuracy of the detection.

A reflector 406 is provided on the other side of the mounting bracket 405. The reflector 406 is mainly used to reflect the laser and together with the reflected light on the surface of the guide rail body 21, it constitutes the optical path required for detection. The detector 403 is installed on the top of the mounting bracket 405 to receive the laser signal after passing through a specific optical path and convert it into an electrical signal for subsequent processing. The detector 403 can use a Hamamatsu Photonics (Hamamatsu) S1133-01 detector. A mounting plate 407 is provided in the mounting bracket 405, and the beam splitter 404 is installed on the mounting plate 407. The beam splitter 404 is in a core position in the entire optical path system, located between the laser emitter 402 and the detector 403 and the reflector 406. It can split the laser beam emitted by the laser transmitter 402 according to a specific ratio and direction, thereby forming different optical paths. The beam splitter 404 can be a Thorlabs CM1-BS013 beam splitter. In order to ensure that the beam splitter 404 can play its role accurately, the mounting bracket 405 is provided with an irradiation sleeve 408 corresponding to the beam splitter 404. The irradiation sleeve 408 can limit the propagation path of the laser and reduce the interference of external factors on the laser propagation.

[0026] A connector 409 is provided above the mounting base 401. The connector 409 is detachably connected to the mounting base 401 through multiple sets of screws, which facilitates the installation, maintenance and replacement of the connector 409. The laser emitter 402, the detector 403 and the beam splitter 404 are all connected to the connector 409 through connecting wires. Through the connector 409, the transmission and interaction of electrical signals between these components are realized. The connector 409 is electrically connected to the controller 25, so that the controller 25 can effectively control the laser emitter 402, the detector 403 and other components and receive and process signals.

[0027] A light shielding sleeve 410 is provided between the beam splitter 404 and the laser emitter 402 and the detector 403. The main function of the light shielding sleeve 410 is to block the interference of external light, ensure that the laser propagates in a specific light path, and improve the accuracy of detection. A plurality of card slots 411 are provided on the mounting bracket 405, and a card plate 412 is provided on both sides of the light shielding sleeve 410. The card plate 412 is clamped in the card slot 411. The light shielding sleeve 410 can reduce the influence of external light on the laser beam. A connecting plate 413 is provided on one side of the mounting bracket 405, and a visual recognition module 414 is provided on one side of the mounting bracket 405. A plurality of fixed card slots are provided on the fixed base plate 301, and a plurality of identification blocks 415 are provided above the fixed base plate 301. The identification blocks 415 are clamped in the fixed card slots. The identification blocks 415 are modules that can be recognized by the visual recognition module 414, and the visual recognition module 414 corresponds to one of the identification blocks 415. When the detection component moves, the visual recognition module 414 can identify the recognition block 415, thereby determining the exact position of the detection component, providing a position reference for detecting the wear of the guide rail body 21. The visual recognition module 414 can adopt the Keyence CV-X400 series visual recognition module.

[0028] like Figure 2 , Figure 3 As shown, the spray assembly includes a support frame 501 and a spray pipe 502. The support frame 501 serves as the supporting framework of the entire spray assembly and provides a stable foundation for the installation and operation of other related components. The support frame 501 is slidably connected to the detection base 101 through a slide rail structure, so that the support frame 501 can slide smoothly linearly on the detection base 101. An electric cylinder 503 is installed on the support frame 501. The electric cylinder 503 is a device that can convert electrical energy into mechanical energy, and it can provide lifting and lowering motion. The spray pipe 502 is connected to the axial end of the electric cylinder 503. The telescopic movement of the electric cylinder 503 can control the up and down movement of the spray pipe 502, and the spray pipe 502 is located above the guide rail body 21, so that the spray pipe 502 can accurately apply the spray material to the surface of the guide rail body 21. An infusion pump 504 and a liquid storage tank 505 for storing magnesium fluoride liquid are provided on the detection base 101. The liquid storage tank 505 is a container for storing magnesium fluoride liquid. The magnesium fluoride liquid plays an important role in the detection process and can improve certain characteristics of the surface of the guide rail body 21 to improve the detection effect. The infusion pump 504 is connected to the liquid storage tank 505 and the spraying tube 502 through connecting pipes. The main function of the infusion pump 504 is to extract the magnesium fluoride liquid in the liquid storage tank 505 and transport it to the spraying tube 502 through the connecting pipe. The infusion pump 504 has a stable flow control capability and can adjust the delivery amount of the magnesium fluoride liquid according to actual needs, thereby ensuring uniform spraying of the liquid during the spraying process.

[0029] An assembly bracket 506 is provided on one side of the support frame 501, and the assembly bracket 506 provides an installation position for the air outlet 507. The air outlet 507 provided on the assembly bracket 506 plays an important role after the spraying operation is completed. A fan 508 is provided on the support frame 501, and the fan 508 is connected to the air outlet 507 through an air duct. When the fan 508 is started, it generates an airflow, which is transported to the air outlet 507 through the air duct and then blown out from the air outlet 507. This airflow acts on the surface of the guide rail body 21, which can accelerate the drying of the material sprayed on the guide rail body 21, improve the efficiency of the entire detection process, and avoid adverse effects on subsequent detection operations due to the undried sprayed material.

[0030] like Figure 2 , Figure 8 , Fig.10 As shown, a mounting groove 104 is provided on the detection base 101, and a mounting cover 105 is clamped in the mounting groove 104, thereby forming a relatively closed mounting cavity. The controller 25 and the processor 24 are both located in this mounting cavity, so that the controller 25 and the processor 24 can be better protected and avoid being interfered by external factors such as dust, moisture, and physical collision, etc., ensuring that they operate in a relatively stable environment, thereby ensuring the normal operation of the entire detection device.

[0031] Multiple groups of heat dissipation slots 106 and multiple groups of mounting card slots 107 are respectively provided on both sides of the installation cavity. The existence of the heat dissipation slots 106 is crucial for the temperature control in the installation cavity. Since the controller 25 and the processor 24 generate heat during operation, if the heat cannot be dissipated in time, it may cause the performance of the equipment to decline or even malfunction. Multiple groups of heat dissipation slots 106 provide an effective way to dissipate heat, so that the heat can be dissipated from the installation cavity to the external environment in time. At the same time, a second fan 108 is provided in the installation card slot 107, and a dustproof net 109 is provided on one side of the two groups of second fans 108. The second fan 108 can further enhance the air flow in the installation cavity, accelerate the dissipation of heat, and improve the heat dissipation efficiency. The dustproof net 109 plays a role in filtering dust, preventing external dust from entering the installation cavity through the fan, thereby protecting the controller 25 and processor 24 and other components in the cavity.

[0032] like Figure 2 , Fig. 9As shown, two groups of reinforcement brackets 110 are provided on one side of the detection base 101, and the reinforcement brackets 110 mainly play the role of enhancing the structural stability of the detection base 101. Two groups of positioning through holes 111 are provided on the reinforcement bracket 110, and the detection base 101 has multiple groups of positioning holes 112 corresponding to the positioning through holes 111. The positioning bolts pass through the positioning through holes 111 and are clamped in one group of positioning holes 112. Not only can the reinforcement bracket 110 be firmly fixed on the detection base 101, but also the position of the reinforcement bracket 110 can be flexibly adjusted according to actual needs to meet different installation and use requirements.

[0033] A pad 113 is provided above the detection base 101, and the pad 113 is connected to the two sets of reinforcement brackets 110. The pad 113 provides a flat working platform for the entire detection device. During the detection process, this platform can be used to place some auxiliary tools or documents related to the detection. In addition, a display is also provided on the detection base 101, and the display is electrically connected to the processor 24. The display can display the detection results processed by the processor 24 in an intuitive form, which is convenient for the operator to obtain the detection information in a timely and accurate manner, such as the wear degree of the guide rail body 21, the detection data, etc., so as to carry out subsequent operations and decisions.

[0034] A wear detection method for a wear detection device for a linear guide rail comprises the following steps: Step 1: Preparation; First, the status of each component of the device should be fully checked. After ensuring that all components are normal, the guide rail body 21 is carefully moved to the device, and then the device is connected to the external power supply, and all preparations for the wear detection operation are made; Step 2: Fix the guide rail; Next, the fixing operation of the guide rail body 21 is performed; the guide rail body 21 is placed between the two groups of baffles 306, so that the guide rail body 21 first contacts with one group of baffles 306; at this time, the rotating motors 310 at both ends of the fixed cross bar 303 in the fixing assembly are started, and the rotating motors 310 start to operate and drive the moving gear 308 connected thereto to rotate; since the moving gear 308 and the moving rack 307 are meshed with each other, during the rotation of the moving gear 308, the fixed cross bar 303 will move along the slide bar 304; through this movement of the fixed cross bar 303, the other group of baffles 306 is driven to move toward the direction of the guide rail body 21 until this group of baffles 306 contacts with the guide rail body 21; at the same time, the power-on seat 312 is energized, and the electromagnet inside the power-on seat 312 generates a magnetic attraction. Under the action of this magnetic attraction, the guide rail body 21 will be firmly adsorbed on the power-on seat 312, and the fixing work of the guide rail body 21 is completed; Step 3: spraying of magnesium fluoride coating; After the guide rail body 21 is fixed, the controller 25 controls the two sets of screw slides 102 to start running. The running of the screw slides 102 will drive the entire fixed component to move, and then the fixed component drives the guide rail body 21 to move; when the guide rail body 21 moves to the bottom of the detection component and the spray component, the screw slide 102 stops running; then, the electric cylinder 503 in the spray component starts to extend and retract, and the extension and retraction action of the electric cylinder 503 drives the spray pipe 502 to move downward, so that the spray pipe 502 is located between the two sets of baffles 306; at this time, the infusion pump 504 starts to run, and the infusion pump 504 transfers the fluorine stored in the storage tank 505 through the connecting pipe. The magnesium fluoride liquid is transported to the spraying pipe 502, and the magnesium fluoride liquid is then evenly sprayed on the upper surface of the guide rail body 21 through the nozzle arranged on the spraying pipe 502; at the same time, the fan 508 starts to run, and the airflow generated by the fan 508 enters the air outlet 507 through the air duct, and then blows from the air outlet 507 to the surface of the guide rail body 21, which can accelerate the drying of the coating; and in this process, the spraying component will move linearly on the detection base 101 through the slide rail structure, so as to spray the magnesium fluoride coating on the entire guide rail body 21, ensuring that the entire upper surface of the guide rail body 21 can be evenly sprayed with the magnesium fluoride coating; Step 4: Wear detection; After completing the above operations, wear detection is performed; the controller 25 issues a command to make the electric slider 23 slide on the slide rail 22 of the detection frame 103, and the sliding of the electric slider 23 will drive the detection component to move; when the visual recognition module 414 on one side of the mounting bracket 405 recognizes the recognition block 415 on the fixed bottom plate 301, the electric slider 23 stops moving; at this time, the laser emitter 402 is turned on, and the laser emitted by the laser emitter 402 passes through the beam splitter 404 and forms two groups of lasers; one of the laser beams is directed to the surface of the guide body 21 and reflected, and the other laser beam is irradiated to the reflective plate 406 and then reflected back. These two laser beams After rejoining at the beam splitter 404, the optical signals are received by the detector 403; after receiving the optical signal, the detector 403 converts the optical signal into an electrical signal, and then transmits it to the connector 409, which then transmits the signal to the controller 25; after receiving the signal, the controller 25 transmits the signal to the processor 24 for analysis and processing, and the processor 24 determines whether the guide rail body 21 is worn and the degree of wear according to the processing result; after the detection of this position is completed, the electric slider 23 continues to move until it moves to the next set of identification blocks 415, and then restarts the above detection steps, thereby performing a comprehensive detection of different positions of the guide rail body 21; Step 5: Recording of test results and subsequent processing; The processor 24 transmits the final detection result to the controller 25, and the controller 25 records and stores the detection result; at the same time, the detection result will be displayed on the display, which is convenient for the operator to observe and record; when it is detected that the wear degree of the guide rail body 21 exceeds 0.1±0.02 mm, it indicates that the wear of the guide rail body 21 is serious, and it is necessary to take measures such as maintenance or replacement in time to ensure the normal operation of the equipment; when the wear degree is less than 0.1 mm within the normal range, the guide rail body 21 can continue to be used normally; Step 6: Check the components are in place; After the detection is completed, the detection component needs to be returned to its original position; the controller 25 sends out an instruction again, the electric slider 23 will slide in the opposite direction, and the reverse sliding of the electric slider 23 will drive the detection component back to the initial position; at the same time, the spray component will also be restored to its original position through the slide rail structure; then, the two sets of screw slides 102 start to run, and the operation of the screw slides 102 will move the fixed component outward; in this process, first, the power supply seat 312 is turned off to release the adsorption effect on the guide rail body 21; at the same time, the rotating motor 310 rotates in the opposite direction, and the reverse rotation of the rotating motor 310 will cause the fixed cross bar 303 to move outward, so that the distance between the two sets of baffles 306 will be expanded, thereby releasing the fixation of the guide rail body 21; finally, the guide rail body 21 is removed to prepare for the next inspection of the guide rail body 21.

[0035] Embodiment 2: Based on the wear detection device and detection method for a linear guide provided in Embodiment 1 of the present application, Embodiment 2 of the present application proposes a wear detection device and detection method for a linear guide. Embodiment 2 is only a preferred method of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. The second embodiment of the present invention will be further described below.

[0036] like Figure 4As shown, the spray assembly includes a support frame 501 and a spray pipe 502.

The support frame 501 is slidably connected to the detection base 101 through a slide rail structure, so that the support frame 501 can slide smoothly linearly on the detection base 101. An electric cylinder 503 is installed on the support frame 501. The electric cylinder 503 is a device that can convert electrical energy into mechanical energy, and it can provide lifting and lowering motion. The spray pipe 502 is connected to the axial end of the electric cylinder 503. The telescopic movement of the electric cylinder 503 can control the up and down movement of the spray pipe 502, and the spray pipe 502 is located above the guide rail body 21, so that the spray pipe 502 can accurately apply the spray material to the surface of the guide rail body 21. An infusion pump 504 and a liquid storage tank 505 for storing magnesium fluoride liquid are provided on the detection base 101. The liquid storage tank 505 is a container for storing magnesium fluoride liquid. The magnesium fluoride liquid plays an important role in the detection process and can improve certain characteristics of the surface of the guide rail body 21 to improve the detection effect. The infusion pump 504 is connected to the liquid storage tank 505 and the spraying tube 502 through connecting pipes. The main function of the infusion pump 504 is to extract the magnesium fluoride liquid in the liquid storage tank 505 and transport it to the spraying tube 502 through the connecting pipe. The infusion pump 504 has a stable flow control capability and can adjust the delivery amount of the magnesium fluoride liquid according to actual needs, thereby ensuring uniform spraying of the liquid during the spraying process.

[0037] An assembly bracket 506 is provided on one side of the support frame 501, and an installation barrel 509 is provided on the assembly bracket 506. The installation barrel 509 provides an installation space for the heating wire 510. The heating wire 510 is installed in the installation barrel 509, and heat is generated when the heating wire 510 is powered on. A thermostat 511 is provided on the support frame 501, and the thermostat 511 is electrically connected to the heating wire 510 and the controller 25 respectively. The thermostat 511 can control the heating temperature of the heating wire 510, and adjust the degree of heating according to different needs. The thermostat 511 can use an OMRON E5CC series thermostat. A first fan 512 is also provided at one end of the installation barrel 509, and the first fan 512 plays a role in promoting heat dissipation and air flow during the heating process. When it is necessary to quickly dry the sprayed material on the surface of the guide rail body 21 or preheat the guide rail body 21, the heating wire 510 generates heat and the first fan 512 blows hot air to the surface of the guide rail body 21, thereby improving the drying efficiency or improving the state of the surface of the guide rail body 21 to meet the detection requirements.

[0038] The difference between the second embodiment and the first embodiment is that a mounting tube 509 is provided on the support frame 501, a heating wire 510 is provided in the mounting tube 509, and a first fan 512 is provided at one end of the mounting tube 509; when magnesium fluoride is sprayed on the surface of the guide rail body 21, the airflow is blown to the surface of the guide rail body 21 by the first fan 512, and at the same time, the heating wire 510 can heat the airflow, and the heated airflow is blown to the surface of the guide rail body 21, which can not only accelerate the drying speed of the magnesium fluoride coating, but also help to improve the bonding effect between the coating and the surface of the guide rail body 21, and provide better conditions for subsequent detection or other operations. The remaining conditions are consistent with those of the first embodiment, so this embodiment will not be repeated.
