Description

Technical Field

[0001] The invention relates to the technical field of on-machine measurement control, in particular to a V-groove guide rail on-machine machining measurement system and method thereof. Background Art

[0002] On Machine Inspection (OMI) refers to the use of machine tool hardware and corresponding measuring tools to measure geometric features in real time during the workpiece processing, and guide subsequent process improvements based on the inspection results. This technology combines hardware and software, and can directly measure the size and position of the workpiece during the processing, automatically correct the offset of the tool or workpiece, and improve the processing accuracy. With the continuous development of the CNC machining industry, parts are becoming more and more complex, and dimensional accuracy is constantly improving. On-machine dimensional measurement is becoming more and more popular as part of the overall processing. Using the probe installed on the machine tool itself for on-machine measurement has the advantages of low cost, high efficiency, and high degree of integration with processing compared to special equipment detection.

[0003] Precision guide rails are widely used, covering a wide range of fields, from CNC machine tools, automated production lines to electronic equipment manufacturing. These application scenarios have extremely high requirements for accuracy, speed and reliability, and precision guide rails can meet these requirements and ensure the accuracy and stability of the equipment. However, to process these precision guide rails, either high-end precision machine tools are required, or initial processing on the machine tool is required, then the machine is stopped for inspection, and then processing again; therefore, the processing cost is high and the efficiency is extremely low. Summary of the invention

[0004] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a V-groove guide rail machining measurement system and method thereof to solve the technical problem that it is impossible to directly measure the precision guide rail while machining.

[0005] The present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a V-groove guide rail machining measurement system, comprising a measurement body connected to a machine tool; the control end of the measurement body is connected to the drive end of the machine tool via a controller, and the measurement end of the measurement body is placed in parallel with the grinding wheel of the machine tool in the V-groove of the guide rail to be measured; The measuring body comprises a sensor and two sets of retractable measuring rod assemblies; Two groups of retractable measuring rod assemblies are respectively arranged at the two ends of the sensor and are connected to the control end of the controller through the sensor; the measuring end is a measuring ball arranged at the end of the two groups of retractable measuring rod assemblies.

[0006] Preferably, the retractable measuring rod assembly comprises a retractable cylinder and a measuring support rod; The retracting cylinder is arranged at the end of the sensor and is connected to the control end of the controller through the sensor; The driving end of the contraction cylinder is connected to one end of the measuring support rod, and the measuring ball and the grinding wheel are respectively arranged at the other end of the measuring support rod.

[0007] Furthermore, a rotating block is provided at the position where the measuring ball is provided on the measuring support rod, and the measuring ball is provided on the rotating block for circumferential rotation.

[0008] Furthermore, an elastic member is provided between the measuring ball and the rotating table.

[0009] Furthermore, the width between the outer sides of the two measuring balls and the width of the grinding wheel correspond to the width between the V-grooves of the guide rail to be measured.

[0010] Furthermore, the measuring ball and the center of the grinding wheel are located in the same plane.

[0011] Furthermore, when the width of the V-shaped groove of the guide rail to be measured is smaller than the spacing between the measuring support rods at both ends of the sensor, the measuring ball contacts the outer walls on both sides of the V-shaped groove of the guide rail to be measured.

[0012] Furthermore, when the width of the V-shaped groove of the guide rail to be measured is smaller than the distance between the measuring support rods at both ends of the sensor, the measuring ball contacts the outer walls on both sides of the V-shaped groove of the guide rail to be measured.

[0013] Preferably, the sensor is connected to the driving end of the machine tool via a cable through a controller.

[0014] In a second aspect, the present invention further provides a V-groove guide rail machining measurement method, based on the above-mentioned V-groove guide rail machining measurement system, comprising the following process: Before processing, after the controller receives the processing start instruction from the machine tool, it controls the movement of the retracting measuring rod assembly, shrinks the spacing of the retracting measuring rod assembly, and places the measuring ball at the end of the retracting measuring rod assembly at the specified position of the guide rail to be measured. When the retracting measuring rod assembly is retracted, the measuring ball will rely on elastic force to stick to both sides of the V-groove of the guide rail to be measured; When the grinding process starts, the machine tool drives the sensor forward, and the measuring ball moves synchronously with the grinding wheel. The controller collects the grinding dimensions of the V-groove of the guide rail to be measured in real time based on the measuring ball, and compares it with the preset dimension value. When the grinding dimension reaches the preset value, the controller immediately sends a stop signal. After the machine tool receives the signal, the V-groove of the guide rail to be measured and processed.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a V-groove guide rail machining measurement system, wherein the control end of the measuring body is connected to the driving end of the machine tool via a controller, and the measuring end of the measuring body is placed in parallel with the grinding wheel of the machine tool in the V-groove of the guide rail to be measured, and two groups of retractable measuring rod assemblies are respectively arranged at the two ends of the sensor, and are connected to the control end of the controller through the sensor; the measuring end is a measuring ball arranged at the end of the two groups of retractable measuring rod assemblies; the V-groove of the guide rail to be measured is arranged between the measuring balls and the grinding wheel of the two groups of retractable measuring rod assemblies, and by integrating the measurement and processing functions, real-time measurement can be performed without interrupting the processing process, thereby significantly improving the overall efficiency of measurement and processing. This method of measuring and processing at the same time reduces the conversion time between measurement and processing in the traditional method, and speeds up the production process.

[0016] Furthermore, the retractable measuring rod assembly includes a retractable cylinder and a measuring support rod; the retractable cylinder is arranged at the end of the sensor and is connected to the control end of the controller through the sensor; the driving end of the retractable cylinder is connected to one end of the measuring support rod, and the measuring ball and the grinding wheel are respectively arranged at the other end of the measuring support rod. The precise control of the retractable cylinder enables the measuring support rod to be stably and accurately moved to a predetermined position, thereby ensuring that the measuring ball is in close contact with the V-groove of the guide rail to be measured, thereby achieving high-precision dimensional measurement. The driving function of the retractable cylinder allows the measuring support rod to perform rapid and precise telescopic movements when necessary to adapt to V-groove guide rails of different sizes and shapes. The simultaneous setting of the measuring ball and the grinding wheel enables the system to make necessary processing adjustments during the measurement process. When an error is found in the measurement, the grinding wheel can be corrected immediately, thereby achieving an efficient process of measuring and processing at the same time.

[0017] Furthermore, a rotating block is provided at the position where the measuring ball is provided on the measuring support rod, and the measuring ball is provided on the rotating block for circumferential rotation. The measuring ball can rotate freely in the circumferential direction through the rotating block, which increases the flexibility during measurement. When measuring the V-groove guide rail, the angle of the measuring ball can be adjusted as needed to better adapt to the shape and size of the V-groove, thereby improving the accuracy and reliability of the measurement.

[0018] Furthermore, an elastic member is provided between the measuring ball and the rotating table, which can absorb the impact and vibration generated during the measurement process and provide a buffer and shock absorption effect for the measuring ball. This helps to protect the measuring ball from damage and reduce the measurement error caused by vibration. The elastic member can ensure that the measuring ball maintains stable contact with the V-groove of the guide rail to be measured, and at the same time enables the measuring ball to be pressed tightly between the V-grooves, thereby improving the processing stability.

[0019] Furthermore, the width between the outer sides of the two measuring balls and the width of the grinding wheel correspond to the width between the V-grooves of the guide rail to be measured. During the measurement process, when the measuring ball contacts the V-groove and measures, the grinding wheel will also move to the appropriate position accordingly, ready to make necessary processing adjustments. This synchronization helps improve the efficiency and accuracy of measurement and processing.

[0020] Furthermore, the center of the measuring ball and the grinding wheel are located in the same plane. When the center of the measuring ball and the grinding wheel are located in the same plane, it can be ensured that both have the same reference surface when contacting the V-groove of the guide rail to be measured. This helps to reduce the measurement error caused by inconsistent reference surfaces and improve the accuracy of measurement.

[0021] Furthermore, when the width of the V-groove of the guide rail to be measured is smaller than the spacing between the measuring rods at both ends of the sensor, the measuring ball contacts the outer walls of the V-groove of the guide rail to be measured, so that the measuring system can be applied to the case where the width of the V-groove is smaller, even if the width of the V-groove is smaller than the spacing between the measuring rods. The contact between the measuring ball and the outer walls of the V-groove ensures accurate measurement even in a small space. Since the measuring ball can contact the outer walls of the V-groove, the system can adapt to V-grooves of different widths and shapes, improving the flexibility and versatility of measurement.

[0022] Furthermore, when the width of the V-groove of the guide rail to be measured is greater than the spacing between the measuring rods at both ends of the sensor, the measuring ball contacts the inner walls on both sides of the V-groove of the guide rail to be measured, so that the measuring system can flexibly adapt to V-grooves of different widths, especially when the width of the V-groove is greater than the spacing between the measuring rods. The contact between the measuring ball and the inner walls on both sides of the V-groove ensures the accuracy and reliability of the measurement and broadens the application range of the measuring system.

[0023] Furthermore, the sensor is connected to the drive end of the machine tool through a cable via the controller. The sensor can collect the measurement data of the V-groove guide rail in real time and quickly transmit the data to the controller through the cable. After receiving the data, the controller can immediately analyze and process it, and issue control instructions to the drive end of the machine tool accordingly. This real-time data transmission and control method ensures the synchronization and accuracy of measurement and processing.

[0024] The present invention also provides a V-groove guide rail machining measurement method, which receives the processing instructions of the machine tool through the controller, and automatically controls the movement of the retracted measuring rod assembly, thereby realizing the automation of measurement and processing. The measuring ball can rely on elastic force to fit tightly on both sides of the V-groove of the guide rail to be measured, ensuring the accuracy of the measurement. At the same time, the measuring ball moves synchronously with the grinding wheel, collects the grinding size in real time, and compares it with the preset value. Once the preset value is reached, a stop signal is immediately issued, thereby realizing an efficient automated measurement and processing process. The present invention realizes the synchronization and stability of measurement and processing through the precise control of the retracted measuring rod assembly, the grinding wheel and the driving end of the machine tool by the controller. At the same time, since the measuring ball moves synchronously with the grinding wheel and can feedback the measurement data in real time, the system can adjust the processing parameters in time to maintain the stability and reliability of the system.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] The object of the present invention is to provide a V-groove guide rail machining measurement system and method thereof, so as to solve the technical problem that it is impossible to directly machine and measure the precision guide rail.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings: Example 1 See also Figure 1 and Figure 2In one embodiment of the present invention, a V-groove guide rail machining measurement system is provided, comprising a measurement body connected to a machine tool; the control end of the measurement body is connected to the driving end of the machine tool via a controller (7), and the measurement end of the measurement body is placed in parallel with the grinding wheel of the machine tool in the V-groove of the guide rail (6) to be measured; the measurement body comprises a sensor 1 and two groups of retractable measuring rod assemblies; the two groups of retractable measuring rod assemblies are respectively arranged at the two ends of the sensor 1, and are connected to the control end of the controller 7 via the sensor 1; the measurement end is a measuring ball 5 arranged at the end of the two groups of retractable measuring rod assemblies, wherein the sensor 1 is installed on the processing station in parallel with the grinding wheel of the machine tool via an auxiliary fixture and a cylinder, and grinding and measurement are performed simultaneously.

[0029] Specifically, the retractable measuring rod assembly includes a retractable cylinder 3 and a measuring support rod 4; The retracting cylinder 3 is arranged at the end of the sensor 1 and is connected to the control end of the controller 7 through the sensor 1; The driving end of the contraction cylinder 3 is connected to one end of the measuring support rod 4 , and the measuring ball 5 and the grinding wheel are respectively arranged at the other end of the measuring support rod 4 .

[0030] In this embodiment, the retractable measuring rod assembly is mainly composed of a retractable cylinder 3 and a measuring support rod 4. The retractable cylinder 3 is a driving component responsible for generating a pushing or pulling force, while the measuring support rod 4 is a connecting and supporting component used to connect the retractable cylinder and the measuring ball 5 and the grinding wheel.

[0031] The precise control of the retracting cylinder in this embodiment enables the measuring support rod to be stably and accurately moved to the predetermined position, thereby ensuring that the measuring ball is in close contact with the V-groove of the guide rail to be measured, achieving high-precision dimensional measurement. The driving function of the retracting cylinder allows the measuring support rod to perform rapid and precise telescopic movement when necessary to adapt to V-groove guide rails of different sizes and shapes. The simultaneous setting of the measuring ball and the grinding wheel enables the system to make necessary processing adjustments during the measurement process. When an error is found during the measurement, the grinding wheel can be corrected immediately, thereby achieving an efficient process of measuring and processing at the same time.

[0032] Specifically, a rotating block 8 is provided at the position where the measuring ball 5 is provided on the measuring support rod 4, and the measuring ball 5 is provided on the rotating block 8 for circumferential rotation.

[0033] In this embodiment, a rotating block 8 is specially designed at the position where the measuring ball 5 is arranged on the measuring support rod 4. The rotating block allows the measuring ball 5 to rotate circumferentially thereon. This design enhances the flexibility of the measuring ball 5, enabling it to better adapt to different angles and shapes of the V-shaped groove, thereby improving the accuracy and adaptability of the measurement.

[0034] Specifically, an elastic member 9 is provided between the measuring ball 5 and the rotating platform 8 .

[0035] In this embodiment, an elastic member 9 is provided between the measuring ball 5 and the rotating block 8. The elastic member 9 (such as a spring, a rubber pad, etc.) provides a certain elasticity and buffer for the measuring ball 5, so that it can maintain a tight fit when contacting the V-shaped groove, while reducing the error caused by impact or friction. In addition, the elastic member also helps the measuring ball to maintain stable rotation on the rotating block.

[0036] Specifically, the width between the outer sides of the two measuring balls 5 and the width of the grinding wheel correspond to the width between the V-grooves of the guide rail 6 to be measured, such as Figure 3 shown.

[0037] In this embodiment, during the grinding process, the measuring ball can follow the movement of the grinding wheel in real time, so as to collect the grinding size of the V-groove in real time. In this embodiment, the center of the measuring ball 5 and the grinding wheel are located in the same plane, which ensures their consistency and accuracy during the processing. If their centers are not in the same plane, it may cause measurement errors or uneven processing.

[0038] Specifically, according to Figure 1 As shown, when the width of the V-groove of the guide rail 6 to be measured is smaller than the distance between the measuring support rods 4 at both ends of the sensor 1, the measuring ball 5 contacts the outer walls of both sides of the V-groove of the guide rail 6 to be measured.

[0039] Specifically, according to Figure 2 As shown, when the width of the V-groove of the guide rail 6 to be measured is smaller than the distance between the measuring support rods 4 at both ends of the sensor 1, the measuring ball 5 contacts the outer walls of both sides of the V-groove of the guide rail 6 to be measured.

[0040] In this embodiment, the sensor 1 is connected to the driving end of the machine tool through the cable 2 via the controller 7 .

[0041] In this embodiment, the sensor 1 is a high-precision inductive displacement sensor that can achieve displacement measurement with a range (≤2mm) and accuracy (≤0.1μm). The controller uses embedded microprocessor technology to collect sensor signals at high speed and communicate the measurement results with the machine tool in various forms such as BCD, serial port, and relay.

[0042] In this embodiment, the control device 7 controls the cylinder to shrink and stop the processing signal according to the process requirements. Figure 4 As shown;.

[0043] In summary, the present invention provides a V-groove guide rail machining measurement system, the control end of the measuring body is connected to the driving end of the machine tool through the controller, and the measuring end of the measuring body is placed in parallel with the grinding wheel of the machine tool in the V-groove of the guide rail to be measured, two groups of retractable measuring rod assemblies are respectively arranged at the two ends of the sensor, and are connected to the control end of the controller through the sensor; the measuring end is a measuring ball arranged at the end of the two groups of retractable measuring rod assemblies; the V-groove of the guide rail to be measured is arranged between the measuring balls and the grinding wheel of the two groups of retractable measuring rod assemblies, and by integrating the measurement and processing functions, real-time measurement can be performed without interrupting the processing process, thereby significantly improving the overall efficiency of measurement and processing. This method of measuring and processing at the same time reduces the conversion time between measurement and processing in traditional methods and speeds up the production process.

[0044] Example 2 This embodiment provides a V-groove guide rail machining measurement method, based on the above-mentioned V-groove guide rail machining measurement system, including the following process: Before processing, after the controller 7 receives the processing start instruction from the machine tool, it controls the movement of the retracting measuring rod assembly, the spacing of the retracting measuring rod assembly is retracted, and the measuring ball 5 at the end of the retracting measuring rod assembly is placed at the specified position of the guide rail 6 to be measured. When the retracting measuring rod assembly is retracted, the measuring ball 5 will be pressed against both sides of the V-groove of the guide rail 6 to be measured by elastic force; When the grinding process starts, the machine tool drives the sensor 1 forward, and the measuring ball 5 moves synchronously with the grinding wheel. The controller 7 collects the grinding dimensions of the V-groove of the guide rail 6 to be measured in real time according to the measuring ball 5, and compares it with the preset dimension value. When the grinding dimension reaches the preset value, the controller 7 immediately sends a stop signal. After the machine tool receives the signal, the V-groove of the guide rail 6 to be measured is measured and processed.

[0045] In summary, the present invention also provides a V-groove guide rail machining measurement method, which receives the processing instructions of the machine tool through the controller, and automatically controls the movement of the retracted measuring rod assembly, thereby realizing the automation of measurement and processing. The measuring ball can rely on elastic force to fit tightly on both sides of the V-groove of the guide rail to be measured, ensuring the accuracy of the measurement. At the same time, the measuring ball moves synchronously with the grinding wheel, collects the grinding dimensions in real time, and compares them with the preset values. Once the preset values ​​are reached, a stop signal is immediately issued, thereby realizing an efficient automated measurement and processing process. The present invention realizes the synchronization and stability of measurement and processing through the precise control of the retracted measuring rod assembly, the grinding wheel and the driving end of the machine tool by the controller. At the same time, since the measuring ball moves synchronously with the grinding wheel and can provide real-time feedback of the measurement data, the system can adjust the processing parameters in time to maintain the stability and reliability of the system.

[0046] The present invention is composed of a sensor and a controller and can be integrated into an ordinary machine tool. During the grinding process of the guide rail, the sensor detects the size of the guide rail in real time. Once the size is qualified, a signal is immediately sent to the machine tool. The machine tool stops processing after receiving the signal, thereby ensuring the consistency of the guide rail size and greatly improving the processing efficiency.

[0047] The present invention achieves precise contraction of the measuring rod spacing by precisely controlling the action of the contraction cylinder through the controller, thereby ensuring that the measuring ball can accurately enter the specified position. The measuring ball relies on the elastic force of the sensor to fit tightly against the inner wall of the guide rail, effectively reducing the measurement error. During the grinding process, the measuring ball moves synchronously with the grinding wheel, and the controller collects sensor data in real time and compares it with the pre-set size value. This real-time feedback mechanism can ensure high-precision control of the processing dimensions, ensure that the consistency of the guide rail dimensions is within 2 microns, and meet the requirements of precision processing. The present invention realizes full-process automated control from measurement to processing, greatly improving processing efficiency. The operator only needs to set the corresponding parameters and programs on the controller to realize automated processing, reducing manual intervention and errors. At the same time, due to the high integration and synchronization of the measurement and processing processes, the processing cycle and downtime are reduced, and the overall production efficiency is improved.

[0048] The present invention aims to solve the problem that precision guide rails are difficult to process and measure, and fully utilizes the advantages of simple structure and easy installation of contact sensors, effectively avoiding the influence of cutting fluid, lubricating fluid, etc. on the measurement of workpieces at the production site. Through the on-machine mode of processing and measuring, the difficult problem of large-size and high-precision measurement at the industrial site is effectively solved.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
