Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a guide detection tool and a detection method for a traverse linear motor of an ultra-precision numerically controlled machine tool. Background Art

[0002] Ultra-precision CNC machine tools can achieve extremely high processing accuracy, reaching sub-micron or even nanometer levels of accuracy, which gives them an incomparable advantage in processing high-precision parts.

[0003] The patent application with publication number CN118543960A discloses an ultra-precision laser processing machine tool, see Figure 5 and Figure 6 As shown, the saddle 87 is floatingly arranged on the bed 89. The bed of the ultra-precision CNC machine tool is provided with a front rail 81 and a rear rail 82. The front rail 81 is provided with a front traverse linear motor 83, and the rear rail 82 is provided with a rear traverse linear motor 84. The front and rear ends of the saddle 87 are respectively connected to the movers on the front traverse linear motor 83 and the rear traverse linear motor 84 through the mover connecting plate 88. The inner side surfaces of the front rail 81 and the rear rail 82 are provided with a grating ruler 85, and the reading head 851 of the grating ruler 85 is connected to the corresponding mover connecting plate 88. When working, the front traverse linear motor 83 and the rear traverse linear motor 84 jointly drive the saddle 87 to reciprocate forward and backward, and the grating ruler 85 feeds back the position signal of the saddle 87 in real time. The front and rear ends of the saddle 87 are respectively connected to the movers of the front and rear traverse linear motors, which requires that the two traverse linear motors must maintain a high degree of synchronization when working.

[0004] Since the traverse linear motor is purchased from outside, there may be a phase angle mismatch between the stator and the mover, which will prevent the motor from moving according to the expected motion trajectory during operation, causing the mover to deviate, shake or vibrate during movement. Once a problem occurs with the traverse linear motor, the two traverse linear motors will move inconsistently, and the saddle may tilt or twist, seriously affecting the processing accuracy and stability of the machine tool. Therefore, it is necessary to perform performance tests on ultra-precision CNC machine tools before leaving the factory to detect the motion performance and phase angle matching of the linear motor and promptly discover possible asynchrony problems in the linear motor during operation, so as to take appropriate adjustment measures to ensure that the saddle moves smoothly and accurately.

[0005] Therefore, it is urgent to develop a guide detection tooling and detection method for the transverse linear motor used in the ultra-precision CNC machine tool. Summary of the invention

[0008] The spanning slide includes a vertical support plate located outside the track and a horizontal span plate spanning the inside and outside of the track; the transmission connecting plate is in a 7-shape and includes a horizontal connecting plate and a vertical connecting plate, and the mounting hole and the first threaded hole are opened on the vertical connecting plate.

[0009] The front and rear adjustment structure includes a plurality of second threaded holes spaced apart on the flat cross plate, a front row positioning holes and a rear row positioning holes arranged on the flat connection plate, the number of the front row positioning holes is the same as that of the second threaded holes and they correspond one to one, the number of the rear row positioning holes is the same as that of the second threaded holes and they correspond one to one, and the third screw is connected to the second threaded hole after passing through the front row positioning hole or the rear row positioning hole.

[0010] As a further improvement of the above technical solution, the side plate is provided with a linear rail extending laterally, and the crossing slide is connected to the linear rail via a slider.

[0011] As a further improvement of the above technical solution, an anti-collision seat for limiting the sliding range of the sliding frame is provided on the side plate.

[0012] As a further improvement of the above technical solution, weight-reducing holes are provided on the vertical support plates and the horizontal span plates of the spanning slide.

[0013] As a further improvement of the above technical solution, the mounting hole is a waist-shaped hole extending vertically.

[0014] The present invention also provides a detection method for a transverse linear motor of an ultra-precision CNC machine tool. A front track and a rear track are provided on the ultra-precision CNC machine tool. A front transverse linear motor is provided on the front track, and a rear transverse linear motor is provided on the rear track. The movers on the front transverse linear motor and the rear transverse linear motor jointly drive the saddle to move through a mover connecting plate. Grating rulers are provided on the inner side surfaces of the front track and the rear track. The detection method comprises the following steps: a. Install the guide detection fixture of the traverse linear motor on the front track, connect the transmission connecting plate to the mover of the front traverse linear motor, and connect the transmission connecting plate to the reading head of the grating ruler; b.

DETAILED DESCRIPTION

[0026] The present invention provides a guide detection tool and detection method for a traverse linear motor of an ultra-precision CNC machine tool. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4 The present invention provides a guide detection tooling for a transverse linear motor of an ultra-precision CNC machine tool, comprising a side plate 2 installed on the outer side of a track 1, a crossing slide 3 that can be laterally slidably arranged on the side plate 2, and a transmission connecting plate 4 located on the inner side of the track 1, the crossing slide 3 and the transmission connecting plate 4 are connected by a front and rear adjustment structure 5, a first threaded hole is provided on one side of the transmission connecting plate 4, the first threaded hole is used to connect with a first screw 44, so that the reading head 851 of the grating ruler 85 is connected to the transmission connecting plate 4; a plurality of mounting holes 41 are opened on the end face of the transmission connecting plate 4 facing the mover 832 of the transverse linear motor, the mounting holes 41 are used for the second screw to pass through and connect to the mover 832 of the transverse linear motor or to form a connection with the mover connecting plate 88.

[0028] It is understandable that there is a certain air gap between the mover 832 and the stator 831 of the traverse linear motor. Theoretically, the mover 832 moves under the action of the magnetic field force and moves in a straight line as expected. However, when the phase angles of the mover 832 and the stator 831 of the traverse linear motor do not match, the mover 832 cannot move smoothly in a straight line. Therefore, the guide detection tooling is used to provide guide constraints for the mover 832, thereby reversely detecting the phase angles of the mover 832 and the stator 831 of the traverse linear motor. The side plate 2 is installed on the outer surface of the track 1 of the ultra-precision CNC machine tool to provide a stable installation foundation. The crossing slide 3 can be arranged on the side plate 2 in a transversely slidable manner, so that the transmission connecting plate 4 connected thereto can also move laterally smoothly together. When the transmission connecting plate 4 is connected to the mover 832 of the transverse linear motor, the transmission connecting plate 4 not only provides a linear motion guide for the mover 832, but also forms a transfer transmission with the mover 832 and the reading head 851 of the grating ruler 85; after the detection starts, when the transverse linear motor is started, stopped, moves at a constant speed, accelerates and decelerates, the reading head 851 of the grating ruler 85 changes position following the mover 832 of the transverse linear motor, and the detection system can detect the movement performance of the transverse linear motor in a no-load state based on the data feedback from the grating ruler 85, thereby judging whether the phase angles of the mover 832 and the stator 831 of the transverse linear motor are consistent.

[0029] When the mover 832 of the transverse linear motor forms a driving connection with the saddle 87 through the mover connecting plate 88, the transverse linear motor is equivalent to being loaded. When the transmission connecting plate 4 is connected to the mover connecting plate 88, the transmission connecting plate 4 also provides a linear motion guide for the mover 832. After the detection starts, when the transverse linear motor is started, stopped, moves at a constant speed, accelerates or decelerates, the reading head 851 of the grating ruler 85 changes position following the mover 832 of the transverse linear motor. The detection system can detect the motion performance of the transverse linear motor under load based on the data fed back by the grating ruler 85, thereby determining whether the phase angles of the mover 832 and the stator 831 of the transverse linear motor are consistent under normal operation.

[0030] The linear motor guide test fixture provided by the present invention can provide guide constraints for the mover 832. In various states such as motor start, stop, uniform motion, acceleration and deceleration motion, the detection system can detect the motion performance of the linear motor under no-load and load conditions according to the data accurately fed back by the grating ruler 85, thereby accurately judging whether the phase angles of the mover 832 and the stator 831 of the transverse linear motor are consistent, effectively improving the accuracy of the detection, and ensuring that the asynchronous problems that may occur during the operation of the motor can be discovered in time. In addition, the linear motor guide test fixture provided by the present invention is cleverly installed with the help of the track 1, and has good versatility. It can be used for detection when the transverse linear motor is no-load, simulating the situation of the motor running alone, and detecting its basic motion performance and phase angle matching; it can also be used for dual-drive synchronous guidance when the motor is loaded (double motors connected to the upper saddle), which is closer to the actual working state, comprehensively evaluates the performance and phase angle consistency of the motor under actual working conditions, ensures that the motor can operate stably under various working conditions, and provides multi-faceted guarantees for the reliable operation of ultra-precision CNC machine tools.

[0031] Specifically, the crossing slide 3 includes a vertical support plate 31 located on the outside of the track 1 and a horizontal cross plate 32 spanning the inside and outside of the track 1; the transmission connecting plate 4 is in a 7-shape and includes a horizontal connecting plate 42 and a vertical connecting plate 43, and the mounting hole 41 and the first threaded hole are provided on the vertical connecting plate 43. The vertical support plate 31 provides a stable support for the crossing slide 3 on the outside of the track 1, and the horizontal cross plate 32 realizes the spanning of the inside and outside of the track 1, so that the crossing slide 3 can be firmly installed on the side plate 2 and connected to the transmission connecting plate 4. This structural design enhances the stability and reliability of the crossing slide 3, ensures that it can withstand forces and vibrations in various motion states during the detection process, ensures the firmness of the overall structure of the detection tooling, and provides a stable foundation for accurately detecting the performance of the traverse linear motor. The transmission connecting plate 4 is designed in a figure-7 shape, in which the flat plate 42 can better fit and connect with other components, increase the contact area, and improve the stability of the connection; the vertical plate 43 is provided with a mounting hole 41 and a first threaded hole, which is convenient for connecting with the mover 832 of the transverse linear motor and the reading head 851 of the grating ruler 85. This design makes the connection more direct and reliable, reduces the detection error caused by unstable connection, and improves the accuracy and reliability of detection.

[0032] Furthermore, the front-to-back positioning structure 5 includes a plurality of second threaded holes spaced apart on the flat cross plate 32, a front row positioning hole 421 and a rear row positioning hole on the flat connection plate 42, the number of the front row positioning holes 421 and the second threaded holes are the same and correspond one to one, the number of the rear row positioning holes and the second threaded holes are the same and correspond one to one, and the third screw 45 is connected to the second threaded hole after passing through the front row positioning hole 421 or the rear row positioning hole. It can be understood that when the performance of the mover 832 needs to be directly detected, the third screw 45 can be connected to the second threaded hole through the front row positioning hole 421, so that the vertical connection plate 43 fits the mover 832, thereby directly obtaining the motion information of the mover 832 and accurately detecting the operating state and phase angle of the mover 832 itself. When it is necessary to consider the overall working condition of the mover 832 after being connected to the saddle 87, the third screw 45 can be selected to pass through the rear positioning hole and connect with the second threaded hole, so that the vertical plate 43 fits with the mover connecting plate 88. In this way, the motor can be tested under the condition of simulating the actual working load, meeting the needs of different testing scenarios and purposes, and improving the adaptability and versatility of the testing tooling.

[0033] The operator only needs to simply change the connection position of the third screw 45 to realize the conversion from the separate detection of the mover 832 to the linkage detection of the mover 832 and the saddle 87, without the need for complicated disassembly and reinstallation of the detection tooling, which greatly improves the detection efficiency, saves detection time and labor costs, and makes switching between different detection requirements more convenient and efficient.

[0034] Furthermore, the side plate 2 is provided with a linear rail 61 extending laterally, and the crossing slide 3 is connected to the linear rail 61 through a slider 62. The cooperation between the linear rail 61 and the slider 62 provides a high-precision linear guide mechanism for the crossing slide 3. The lateral sliding of the crossing slide 3 on the side plate 2 becomes very smooth, with almost no interference from friction resistance. During the detection process of various motion states of the traverse linear motor, the crossing slide 3 can follow the movement of the mover 832 and move smoothly laterally without jamming or jumping, thereby ensuring the continuity and stability of the detection process and providing a good basis for accurately obtaining the motion information of the mover 832.

[0035] Furthermore, the side plate 2 is provided with an anti-collision seat 7 for limiting the sliding range of the crossing slide 3. By providing the anti-collision seat 7, the crossing slide 3 can be prevented from excessively sliding off the linear rail 61.

[0036] Furthermore, weight-reducing holes 33 are provided on the vertical support plates 31 and the horizontal span plates 32 of the span slide 3. The provision of the weight-reducing holes 33 significantly reduces the overall weight of the span slide 3. During the installation and debugging of the detection tooling, the operator needs to carry, position and install the span slide 3. The lighter weight makes these operations easier and more convenient, reduces the labor intensity of the operator and improves work efficiency. At the same time, when installed on the side panel 2, the load pressure on the side panel 2 and other connecting components is also reduced, making the entire installation structure more stable and reliable.

[0037] Furthermore, the mounting hole 41 is a waist-shaped hole extending vertically. The waist-shaped hole extending vertically provides a certain vertical adjustment space for the connection between the mover 832 of the transverse linear motor and the transmission connecting plate 4. Since there may be certain manufacturing errors or installation deviations in the actual production and assembly process, the installation heights of different movers 832 of the transverse linear motor may be slightly different. The design of the waist-shaped hole enables the transmission connecting plate 4 to adapt to such differences within a certain range. By adjusting the position of the connecting screw in the waist-shaped hole, the transmission connecting plate 4 can be conveniently and accurately connected to the mover 832, thereby improving the installation adaptability and versatility of the detection tooling and reducing the installation difficulties and adjustment workload caused by size mismatch.

[0038] See Figure 5 and Figure 6 As shown, the manufactured ultra-precision CNC machine tool is provided with a front rail 81 and a rear rail 82, the front rail 81 is provided with a front traverse linear motor 83, the rear rail 82 is provided with a rear traverse linear motor 84, the movers 832 on the front traverse linear motor 83 and the rear traverse linear motor 84 jointly drive the slide saddle 87 to move through the mover connecting plate 88, and the inner side surfaces of the front rail 81 and the rear rail 82 are provided with a grating ruler 85. Figure 7 As shown, the present invention also provides a method for detecting a traverse linear motor of an ultra-precision CNC machine tool, comprising the following steps: a. Install the above-mentioned traverse linear motor guide detection fixture on the front track 81, the transmission connecting plate 4 is connected to the mover 832 of the front traverse linear motor 83, and the transmission connecting plate 4 is connected to the reading head 851 of the grating ruler 85; b. Install the above-mentioned traverse linear motor guide detection tooling on the rear track 82; the transmission connecting plate 4 is connected to the mover 832 of the rear traverse linear motor 84, and the transmission connecting plate 4 is connected to the reading head 851 of the grating ruler 85; c. The front traverse linear motor 83 and the rear traverse linear motor 84 move synchronously to realize the no-load test and the grating ruler 85 feeds back the signal to the detection system; d. The front traverse linear motor 83 of the mover 832 is driven by the mover connecting plate 88 and the front end of the saddle 87, so that the transmission connecting plate 4 is connected to the mover connecting plate 88; e. The mover 832 of the rear traverse linear motor 84 is connected to the rear end of the saddle 87 through the mover connecting plate 88, so that the transmission connecting plate 4 is connected to the mover connecting plate 88; f. The front traverse linear motor 83 and the rear traverse linear motor 84 move synchronously to realize the load test and the grating ruler 85 feeds back the signal to the detection system.

[0039] This detection method covers the detection of motors in both no-load and load states. By first performing a no-load test, it is possible to evaluate the basic characteristics of the traverse linear motor such as its own motion performance and phase angle consistency, eliminate the interference of the inherent problems of the traverse linear motor on the detection results, and accurately understand the operating status of the traverse linear motor under no-load conditions; then a load test is performed to simulate the working conditions in which the traverse linear motor is connected to the saddle 87 and drives the saddle 87 to move in actual work, which more truly reflects the performance of the traverse linear motor in actual work. This comprehensive detection method can ensure that the performance evaluation of the traverse linear motor is not missed, and provides comprehensive and accurate data support for judging whether the motor meets the working requirements of ultra-precision CNC machine tools, effectively improving the accuracy and reliability of the detection.

[0040] The transmission connecting plate 4 is connected to the mover 832 of the front transverse linear motor 83, and the specific operation of connecting the transmission connecting plate 4 to the reading head 851 of the grating ruler 85 is as follows: the transmission connecting plate 4 and the reading head 851 on the grating ruler 85 are connected through the corner block 86, and the first screw 44 cooperates with the first threaded hole of the transmission connecting plate 4 to fix the transmission connecting plate 4 and the corner block 86; the second screw passes through the mounting hole 41 on the transmission connecting plate 4 and is connected to the third threaded hole on the mover 832 of the front transverse linear motor 83 to fix the transmission connecting plate 4 and the mover 832 of the front transverse linear motor 83. The use of the corner block 86 plays a flexible transfer role between the transmission connecting plate 4 and the reading head 851 of the grating ruler 85. Since there may be certain differences in the installation position and angle of the reading head 851 of the grating ruler 85 and the transmission connecting plate 4, the corner block 86 can be adjusted and adapted according to the actual situation to make the connection between the two smoother and more accurate. The fixing method using screws is reliable and the positioning is accurate. The staff can use an electric screwdriver to assist in the disassembly and assembly of the screws, which has high work efficiency.

[0041] The specific operations of step b can refer to the specific operations of step a, and will not be repeated here.

[0042] The mover 832 of the front transverse linear motor 83 forms a driving connection with the front end of the saddle 87 through the mover connecting plate 88, so that the specific operation of connecting the transmission connecting plate 4 with the mover connecting plate 88 is as follows: the transmission connecting plate 4 on the front rail 81 is removed and connected with the mover 832 of the front transverse linear motor 83 and the reading head 851 of the grating ruler 85; the mover 832 of the front transverse linear motor 83 is connected with the saddle 87 through the mover connecting plate 88, and the reading head 851 of the grating ruler 85 is connected with the mover connecting plate 88, and the transmission connecting plate 4 is adjusted to the joint with the mover connecting plate 88 through the front and rear adjustment structure 5, and the second screw passes through the mounting hole 41 on the transmission connecting plate 4 and is connected with the fourth threaded hole on the mover connecting plate 88, so that the transmission connecting plate 4 and the mover 832 of the front transverse linear motor 83 are fixedly connected. The operator can easily switch the transmission connecting plate 4 from the no-load detection mode directly connected to the mover 832 to the load detection mode connected to the mover connecting plate 88, without the need for complex disassembly and reassembly of the detection tooling. This ability to quickly switch detection modes greatly improves detection efficiency, saves detection time and labor costs, makes switching between different detection requirements more convenient, and can obtain the performance data of the motor in different working conditions more timely.
