Description

Technical Field

[0001] This invention belongs to the field of flexible wire saw cutting, and mainly relates to a deformation monitoring device and monitoring method for the curved flexible wire saw cutting process. Background Technology

[0002] In recent years, with the rapid development of aerospace, medical industry, mold and die manufacturing, and automotive industry, a large number of complex curved surface parts with high machining difficulty and stringent performance requirements have emerged. Traditional milling and grinding methods for machining curved surfaces suffer from problems such as a small contact area between the tool and the workpiece (point contact machining), large machining allowance, severe tool wear, and low machining efficiency. Adopting flexible wire saw cutting technology can effectively improve machining efficiency and material utilization.

[0003] During the cutting process, the flexible wire saw will bend and deform due to the contact force between the flexible wire saw and the workpiece. This causes the contact position between the flexible wire saw and the workpiece to fail to reach the set coordinate point, resulting in a deviation between the shape of the complex curved surface part processed by the flexible wire saw and the shape of the target workpiece. This fails to meet the shape accuracy requirements, thus causing material waste and economic losses.

[0004] The published patent "An Online Monitoring Device and Method for the Bow of a Multi-Wire Cutting Machine" (Publication No. CN106313353A) proposes using distance sensors such as ultrasonic distance sensors and laser distance sensors to measure the offset distance of the wire saw and calculating the bow angle through trigonometric functions. The published patent "A Method and Device for Detecting Bows in the Cutting Process of Photovoltaic Silicon Wafers" (Publication No. CN107672071) proposes using a telescope lens with a transparent scale to observe the longitudinal height of the wire saw and calculate the bow angle through geometric angles; the lens has a crosshair in the center.

[0005] However, the flexible wire saw deformation monitoring devices and methods proposed in the aforementioned published patents are only applicable to deformation monitoring when the flexible wire saw is cutting flat workpieces, and do not mention monitoring devices and methods for flexible wire saw deformation during the cutting of complex curved parts. As the application of flexible wire saws in the processing of complex curved parts becomes increasingly widespread, monitoring the deformation of flexible wire saws during the cutting process of complex curved parts is of great significance.

[0006] In view of this, this application proposes a deformation monitoring device and method for the process of flexible wire saw cutting complex curved surface parts, which fills the gap in the field of monitoring devices and methods for the processing of complex curved surface parts by flexible wire saw cutting. Summary of the Invention

[0007] The purpose of this invention is to solve the problem of deviation in cutting results and shape accuracy caused by the deformation of the flexible wire saw when cutting complex curved parts. Therefore, a deformation monitoring device and monitoring method for the flexible wire saw cutting process of curved surfaces are provided.

[0008] To address the aforementioned technical problems, this invention provides a deformation monitoring device for the curved flexible wire saw cutting process. The deformation monitoring device includes a fixed support base, a first monitoring device, a second monitoring device, and a data acquisition system. The fixed support base is fixed to a flexible wire saw cutting device, which includes a flexible wire saw arranged along the X-axis. The first monitoring device is arranged along the Z-axis, and the second monitoring device is arranged along the Y-axis.

[0013] In a preferred embodiment, the spring displacement sensor is connected to the data acquisition system via a voltage signal output line.

[0014] In a preferred embodiment, the sensor fixture includes a slot in which the spring displacement sensor is mounted;

[0015] The spring displacement sensor moves within the slot to adjust the position of the roller probe, so that the roller center surface of the roller probe is coplanar with the flexible wire saw.

[0016] In a preferred embodiment, the first monitoring device is provided with a Z-direction sensor clamp, and the second monitoring device is provided with a Y-direction sensor clamp support and a Y-direction sensor clamp.

[0017] The Z-direction sensor fixture is provided with a Z-direction slot, the Y-direction sensor fixture support is provided with a Y-direction slot, and the fixed support is provided with an X-direction slot.

[0018] The Z-direction sensor fixture is slidably mounted on the fixed support base through a Z-direction slot and an X-direction slot; the Y-direction sensor fixture support base is slidably mounted on the fixed support base through an X-direction slot; the Y-direction sensor fixture is slidably mounted on the Y-direction sensor fixture support base through a Y-direction slot; the position of the roller side head is adjusted by sliding through the slots so that the roller side head contacts the flexible wire saw, ensuring the X-direction distance between the first monitoring device and the second monitoring device.

[0019] In a preferred embodiment, the roller is made of a wear-resistant material, which is polyurethane or polyethylene;

[0020] The flexible wire saw is a bonded abrasive wire saw, a free abrasive wire saw, a rope saw, or an EDM electrode wire saw.

[0021] In a preferred embodiment, the flexible wire saw deviates in the opposite direction of the workpiece feed direction during the cutting process of a complex curved workpiece, resulting in wire saw deformation. The spring displacement sensor retracts under the force of the flexible wire saw, causing a change in the output voltage signal, which is fed back to the data acquisition system.

[0022] The present invention also provides a deformation monitoring method for the curved flexible wire saw cutting process, using the aforementioned deformation monitoring device;

[0023] The deformation monitoring method includes:

[0025] Step B: Install the deformation monitoring device; the flexible wire saw is arranged along the X-axis direction, the roller probe of the first monitoring device contacts the flexible wire saw along the Z-axis direction; the roller probe of the second monitoring device contacts the flexible wire saw along the Y-axis direction;

[0026] Step C: Calibrate and calculate the deformation of the flexible wire saw under non-cutting conditions; control the worktable to feed in the horizontal and vertical directions respectively, monitor the deformation of the flexible wire saw through the spring displacement sensor, and monitor the relationship between the output voltage signal and the feed time through the spring displacement sensor; the data acquisition system calculates the relationship between the feed displacement and the feed time through the feed speed, and obtains the mathematical relationship between the feed displacement and the output voltage signal through fitting, that is, the mathematical relationship between the deformation of the flexible wire saw and the output voltage signal;

[0027] Step D: Real-time monitoring of the deformation of the flexible wire saw during the cutting process; the cutting process begins, and there is a force between the flexible wire saw and the workpiece, causing the flexible wire saw to bend and deform. Using the mathematical relationship between the deformation of the flexible wire saw and the output voltage signal obtained in step C, the changes of the deformation of the flexible wire saw in the vertical and horizontal directions over time are calculated based on the output voltage signal obtained in real time.

[0029] In a preferred embodiment, the roller contacts the flexible wire saw and moves a certain distance along the feed direction of the flexible wire saw after the flexible wire saw is tensioned, so that the spring displacement sensor has a certain distance of retraction before the deformation monitoring of the flexible wire saw begins.

[0030] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0031] 1. This invention provides a deformation monitoring device and method for flexible wire saw cutting of curved surfaces.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0041] refer to Figures 1-3 This embodiment provides a deformation monitoring device for the cutting process of a curved flexible wire saw, such as... Figure 1As shown, the deformation monitoring device includes a fixed support base 1, a first monitoring device, a second monitoring device, and a data acquisition system 14 (with built-in input power supply); the fixed support base 1 is fixed to the flexible wire saw 8 cutting device by bolts, the flexible wire saw 8 cutting device includes a flexible wire saw 8, which is set along the X-axis direction; the first monitoring device is set along the Z-axis direction, and the second monitoring device is set along the Y-axis direction.

[0042] The first monitoring device includes a Z-direction sensor clamp 2 and a spring displacement sensor 3 mounted on the Z-direction sensor clamp 2. The Z-direction sensor clamp 2 is mounted on the fixed support base 1. The second monitoring device includes a Y-direction sensor clamp support base 11, a Y-direction sensor clamp 13, and a spring displacement sensor 3 mounted on the Y-direction sensor clamp 13. The Y-direction sensor clamp support base 11 is mounted on the fixed support base 1, and the Y-direction sensor clamp 13 is mounted on the Y-direction sensor clamp support base 11.

[0043] The spring displacement sensor 3 includes a roller 6 probe, which comprises a roller 6, a roller clamp 5, and a roller clamp locking disc 4. The roller clamp 5 is threadedly mounted on the spring displacement sensor 3, and the roller 6 is mounted on the roller clamp 5 via rolling bearings. The rotation angle of the roller clamp 5 is adjusted by the roller clamp locking disc 4 to ensure that the rolling direction of the roller 6 is parallel to that of the flexible wire saw 8, thereby reducing wear on the roller 6 during wire saw deformation monitoring.

[0044] The spring displacement sensor 3 is connected to the data acquisition system 14 via a voltage signal output line 12, and outputs the monitored voltage signal to the data acquisition system 14 via the voltage signal output line 12. The data acquisition system 14 collects the deformation data of the flexible wire saw 8.

[0045] The flexible wire saw 8 cutting device includes a guide wheel 7, a flexible wire saw 8 and a worktable 10. The flexible wire saw 8 includes, but is not limited to, bonded abrasive wire saws, free abrasive wire saws, wire saws or EDM wire saws, etc.

[0046] The roller 6 can be made of high-molecular wear-resistant materials such as polyurethane and polyethylene to avoid severe wear of the roller 6 during the deformation monitoring process of the flexible wire saw 8, which would affect the monitoring results.

[0047] The Z-direction sensor fixture 2 has a Z-direction slot, the Y-direction sensor fixture support 11 has a Y-direction slot, and the fixed support 1 has an X-direction slot. The Z-direction sensor fixture 2 is secured to the X-direction slot by bolts passing through it, and rotating the bolts allows it to slide relative to the fixed support 1 within either the Z-direction or X-direction slot. The Y-direction sensor fixture support 11 is secured to the X-direction slot by bolts passing through it, and rotating the bolts allows it to slide relative to the fixed support 1 within the X-direction slot. The Y-direction sensor fixture 13 is secured to the Y-direction slot by bolts passing through it, and rotating the bolts allows it to slide relative to the Y-direction sensor fixture support 11 within the Y-direction slot.

[0048] The Z-direction sensor fixture 2, through a Z-direction slot, allows adjustment of the vertical distance between the Z-direction sensor fixture 2 and the fixed support base 1, ensuring that the roller 6 of the spring displacement sensor 3 in the Z-direction direction contacts the flexible wire saw 8. Similarly, the Y-direction sensor fixture 13, through a Y-direction slot, allows adjustment of the horizontal distance between the Y-direction displacement sensor fixture 13 and the Y-direction sensor fixture support base 11, ensuring that the roller 6 of the spring displacement sensor 3 in the Y-direction direction contacts the flexible wire saw 8.

[0049] Both the Z-direction sensor fixture 2 and the Y-direction sensor fixture 13 are provided with slots. The spring displacement sensor 3 is installed in the slots. The spring displacement sensor 3 can adjust the horizontal position of the displacement sensor relative to the Z-direction sensor fixture 2 or the vertical position of the spring displacement sensor 3 relative to the Y-direction sensor fixture 13 through the slots, and adjust the position of the roller 6 probe so that the roller 6 probe contacts the flexible wire saw 8, ensuring that the mid-plane of the roller 6 is coplanar with the flexible wire saw 8, and avoiding excessive deformation of the flexible wire saw 8 during the monitoring process, which could cause the flexible wire saw 8 to detach from the roller 6.

[0050] The roller 6 contacts the flexible wire saw 8, and after the flexible wire saw 8 is tensioned, the roller 6 moves a certain distance along the feed direction of the flexible wire saw 8 to ensure that the spring displacement sensor 3 has a certain distance of retraction before the deformation monitoring of the flexible wire saw 8 begins, thereby improving the accuracy of the wire saw deformation monitoring process.

[0051] When the flexible wire saw 8 deviates in the opposite direction of the workpiece feed direction during the cutting process of the complex curved workpiece, the wire saw deforms. The spring displacement sensor 3 retracts under the force of the flexible wire saw 8, causing a change in the output voltage signal, which is fed back to the data acquisition system 14 of the flexible wire saw 8 deformation.

[0052] A deformation monitoring method for the cutting process of a curved flexible wire saw includes:

[0053] Step A: Install the cutting workpiece 9; Attach the cutting workpiece 9 to the worktable 10 of the flexible wire saw 8 cutting equipment with adhesive;

[0054] Step B: Install the deformation monitoring device for the flexible wire saw 8 during the cutting of complex curved surface parts; install the fixed support 1, Z-direction sensor fixture 2, Y-direction sensor fixture support 11, Y-direction sensor fixture 13, spring displacement sensor 3, roller fixture 5, roller fixture locking disc 4, roller 6, voltage signal output line 12, power supply, and flexible wire saw 8 deformation data acquisition system 14. The flexible wire saw 8 is set along the X-axis direction, and the roller 6 probe of the spring displacement sensor 3 corresponding to the Z-direction is in contact with the flexible wire saw 8 along the Z-axis direction; the roller 6 probe of the spring displacement sensor 3 corresponding to the Y-direction is in contact with the flexible wire saw 8 along the Y-axis direction.

[0055] Step C: Calibrate and calculate the deformation of the flexible wire saw 8 under non-cutting processing conditions; The calibration process of the output voltage signal and the deformation of the flexible wire saw 8 is carried out under non-cutting processing conditions. The worktable 10 is controlled to feed in the horizontal and vertical directions respectively. The deformation of the flexible wire saw 8 is monitored by the spring displacement sensor 3. The spring displacement sensor 3 monitors the relationship between the output voltage signal and the feed time; The data acquisition system 14 calculates the relationship between the feed displacement and the feed time through the feed speed Vf, and obtains the mathematical relationship between the feed displacement and the output voltage signal through fitting, that is, the mathematical relationship between the deformation of the flexible wire saw 8 and the output voltage signal;

[0056] Step D: Real-time monitoring of the deformation of the flexible wire saw 8 during the cutting process; Cutting begins, and a force exists between the flexible wire saw 8 and the workpiece 9, causing the flexible wire saw 8 to bend and deform. Using the mathematical relationship between the deformation of the flexible wire saw 8 and the output voltage signal obtained in step C, the changes in the deformation of the flexible wire saw 8 in the vertical and horizontal directions over time are calculated based on the real-time monitored output voltage signal. Figure 2 As shown;

[0057] Step E: Fit the actual cutting surface; calculate the actual contact position between the flexible wire saw 8 and the workpiece 9 during the cutting process based on the changes in the deformation of the flexible wire saw 8 in the vertical and horizontal directions over time, and fit the actual cutting surface; such as Figure 3 As shown, by comparing and fitting the actual cutting surface with the target processing surface, the cutting trajectory is adjusted in real time to ensure that the complex surface processed by the flexible wire saw 8 meets the shape accuracy requirements.

[0058] Two mutually perpendicularly installed spring displacement sensors 3 can monitor the bending deformation of the flexible wire saw 8 in real time and accurately, ensuring real-time performance, stability, and full data monitoring of wire saw deformation during the monitoring process, thus filling the gap in the field of monitoring devices and methods for the processing of complex curved surface parts by the flexible wire saw 8.

[0059] Based on the relationship between the deformation of the flexible wire saw 8 in the vertical and horizontal directions and time, the actual contact position between the flexible wire saw 8 and the workpiece 9 during the cutting process is calculated, and the actual cutting surface is obtained by fitting. By comparing the fitted actual cutting surface with the target machining surface, the cutting trajectory is adjusted in real time to ensure that the complex surface after cutting by the flexible wire saw 8 meets the shape accuracy requirements, thus avoiding material waste and economic losses.

[0060] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
