Description

Technical Field

[0001] This application relates to the field of dimensional measurement technology, and in particular to a dimensional measuring instrument for processing Teflon high-temperature fabric. Background Technology

[0002] Teflon high-temperature fabric is widely used in V-cavity hot pressing processes, and the assembly dimensional accuracy after cutting directly determines the quality of hot pressing. Existing dimensional measurement equipment is mostly used for static length and width measurement of sheet and roll materials in a flat state. The measurement benchmark is the free flat state, and dimensional correction measurements are not combined with the actual assembly stress and bending forming conditions of the workpiece.

[0003] Currently, the industry lacks a dedicated method for measuring the dimensions of Teflon high-temperature fabric for V-cavity hot pressing molds. Conventional measurement methods have significant technical limitations: First, conventional measurements can only detect the original dimensions of the fabric when laid flat, and cannot simulate the bending and tilting shape of the Teflon high-temperature fabric assembled inside the V-cavity. The actual formed dimensions after bending and stretching of the fabric deviate from the flat dimensions, resulting in measurement data that cannot correspond to actual assembly and usage conditions, leading to poor detection effectiveness. Second, existing measurement equipment lacks dynamic adaptive clamping and tilt angle following adjustment structures, making it impossible to match the dynamic changes in the side wall tilt angle during the bending of the high-temperature fabric. Problems such as fabric stress deformation, slippage, and wrinkles are prone to occur during the measurement process, making it difficult to stably reproduce the forming state inside the mold. Third, traditional detection methods lack a locking and retaining structure for the forming state. After the fabric is bent and formed, it is prone to springback and offset, resulting in unstable measurement benchmarks and further reducing the accuracy of dimensional measurements under working conditions, failing to meet the detection requirements of high-precision hot pressing processing for the forming dimensions of Teflon high-temperature fabric.

[0004] In summary, existing dimensional measuring equipment has poor adaptability to the working conditions of Teflon high-temperature cloth used in V-cavity hot pressing molds, lacks molding simulation capabilities, and has insufficient stability in maintaining its state. It is difficult to achieve accurate dimensional detection in the simulated mold assembly state. Therefore, there is an urgent need for a dimensional measuring instrument for processing Teflon high-temperature cloth that can dynamically simulate V-bending conditions, adaptively adapt to the cloth tilt angle, and stably lock the molding state.

[0016] Compared with the prior art, the beneficial effects of the embodiments of the present invention are: This invention, by simulating the coordination of various components, can completely replicate the actual bending and forming process of Teflon high-temperature fabric assembled inside a V-cavity hot-pressing mold. This overcomes the shortcomings of existing technologies, which can only perform static measurements of the Teflon high-temperature fabric when laid flat and cannot simulate the bending state of the mold, resulting in significant deviations between measured data and actual assembly dimensions. This invention utilizes a first electric telescopic rod to drive the simulation plate at the bending point to press vertically downwards, simulating the bending deformation process at the center of the high-temperature fabric. Simultaneously, the clamping positions on both sides of the fabric are adjusted through the linkage of the first and second electric slide rails, dynamically matching the displacement and stretching state of the fabric's sides with the central bending and extrusion process. This effectively avoids problems such as wrinkles, localized stretching, and uneven stress in the fabric during the simulated forming process. Meanwhile, the first motor can drive the third electric slide rail to rotate as a whole, causing the clamping plate to adjust the clamping angle in real time, so that the clamping plate always keeps in contact with the dynamically changing side wall angle of the high-temperature cloth. This ensures that there is no additional extrusion stress or local deformation during the bending and forming process of the cloth, and completely restores the forming shape of the Teflon high-temperature cloth in the V-shaped cavity hot press mold. This provides a real measurement basis that fits the actual working conditions for subsequent dimensional inspection, eliminating measurement errors caused by differences in working conditions from the root.

[0017] This invention achieves stable, non-offset, and non-rebound locking of Teflon high-temperature fabric during bending and forming by coordinating the upper and lower support measuring components and the auxiliary holding components. This solves the technical problems of existing measuring equipment where the fabric easily springs back, slips, and exhibits unstable posture after forming, leading to measurement reference drift. The invention uses a second motor to drive a first round rod, rotating and adjusting the support plate to ensure the bottom support surface perfectly matches the inclination angle of the fabric's bent sidewall. A fourth electric telescopic rod extends and retracts to adjust the spacing of the support blocks, achieving full-area fitting support for the fabric's bent sidewall. Simultaneously, a third electric telescopic rod enables precise alignment and lifting of the bottom support structure, establishing a stable bottom support reference. Meanwhile, the auxiliary holding component uses a seventh electric slide rail to horizontally align the holding plate. A third motor drives a second round rod to adaptively adjust the holding plate's angle, ensuring the inclination angle perfectly matches the fabric sidewall. A fifth electric telescopic rod then precisely presses down to position the holding plate. By combining the flexible limiting of the top retaining plate with the rigid support of the bottom support plate and support block, the fabric can still be firmly locked in the simulated forming state after the side clamping plate is released, effectively preventing problems such as fabric springback, lateral displacement, and angular deformation, ensuring the consistency and stability of the measurement conditions throughout the process, and providing a stable attitude reference for high-precision dimensional detection.

[0018] This invention utilizes a support and measurement component to achieve precise and automated detection of the length and width dimensions of Teflon high-temperature fabric under working conditions, overcoming the shortcomings of existing technologies such as single measurement dimension, poor adaptability, inaccurate contact judgment, and low dimensional conversion accuracy. This invention uses a fifth and sixth electric slide rail to drive the corresponding sliding plate and measuring plate, respectively. Relying on the cooperative structure of pressure sensors, detection springs, and side plates and contact plates, it achieves accurate determination of effective contact with the fabric sidewall, avoiding deformation errors caused by rigid detection squeezing the fabric or detection failures caused by false contact. Simultaneously, through the multi-stroke linkage of the fourth, fourth, and sixth electric slide rails, the length dimension can be accurately converted according to the actual shape of the fabric after bending and forming. Combined with the stroke of the fifth electric slide rail, the width dimension is detected, achieving precise full-range measurement of the entire length and width of the Teflon high-temperature fabric in the formed state. The entire testing structure can adapt to different bending angles and specifications of Teflon high-temperature cloth. It has wide measurement adaptability and a high degree of automation. No manual alignment or measurement is required throughout the process, avoiding subjective errors caused by manual operation and greatly improving the accuracy and efficiency of Teflon high-temperature cloth processing dimension testing.

[0029] Working principle: When performing dimensional measurement on the cut Teflon high-temperature cloth under mold assembly conditions, the Teflon high-temperature cloth to be tested is first placed stably in the test station area between the top of the support plate 39 of the support measurement component 3 and the bending simulation plate 22 of the simulation component 2, thus completing the initial positioning of the cloth to be tested.

[0030] After initial positioning, the first electric slide rail 24 in the first groove 23 inside the mounting frame 1 is activated. The first electric slide rail 24 drives the first sliding plate 25 to move laterally, causing the mounting plate 26 to move synchronously, so that the mounting plate 26, the second electric slide rail 27, the second sliding plate 28, and the fixing frame 29 move closer to the two side edges of the Teflon high-temperature cloth. When the clamping plate 215 inside the fixing frame 29 is aligned with the two side walls of the Teflon high-temperature cloth, the first electric slide rail 24 is closed, and the second electric telescopic rod 214 is activated, driving the clamping plate 215 to move. The clamping plate 215 is used to fix the side walls of the Teflon high-temperature cloth, completing the initial alignment and positioning of the clamping mechanism. Then, the third electric slide rail 211 is activated, causing the third sliding plate 212 to drive the clamping plate 215 to move, so that the Teflon high-temperature cloth is directly above the support plate 39.

[0031] After the workstation is aligned, the first electric telescopic rod 21 at the top of the mounting frame 1 is activated. The telescopic end of the first electric telescopic rod 21 drives the bending simulation plate 22 to move vertically downward, vertically pressing the center of the Teflon high-temperature cloth, thus simulating the center bending forming state when the Teflon high-temperature cloth is assembled inside the V-shaped cavity hot press mold. During the entire process of the bending simulation plate 22 being pressed downward, the first electric slide rail 24 and the second electric slide rail 27 are activated simultaneously. Through the displacement of the first slide plate 25 and the second slide plate 28, the clamping ends on both sides of the Teflon high-temperature cloth are driven to move synchronously and adaptively, so that the stretching and displacement speed of the cloth on both sides is precisely matched with the center bending and pressing speed, avoiding wrinkles and local stretching deformation of the cloth, ensuring that the bending forming state conforms to the actual working conditions of the mold, and simultaneously controlling the first motor 210 to start, driving the third electric slide rail 211 to rotate, so that the clamping plate 215 rotates accordingly, ensuring that the inclination angle of the clamping plate 215 is always the same as the inclination angle of one side of the Teflon high-temperature cloth, so that the clamping plate 215 conforms to the cloth and evenly distributes the clamping force; After the fabric forming state is locked, the second motor 37 on the side wall of the first clamping plate 35 is activated. The output end of the second motor 37 drives the first round rod 36 to rotate, causing the connecting plate 38 and the support plate 39 to rotate synchronously. The overall tilt angle of the support plate 39 is adjusted in real time so that the tilt angle of the support plate 39 is fully adapted to the tilt angle of the side wall of the current Teflon high-temperature fabric. After the adaptation is completed, the second motor 37 is turned off, and the angle calibration of the bottom support reference is completed. Then, the fourth electric telescopic rod 314 inside the mounting groove 313 of the support plate 39 is activated. The fourth electric telescopic rod 314 drives the support block 315 to extend and retract horizontally, adjusting the distance between the support block 315 and the support plate 39 so that the distance is adapted to the extension length of the bent side wall of the Teflon high-temperature fabric, ensuring subsequent full-area support and fit. After the distance adjustment is completed, the fourth electric telescopic rod 314 is turned off.

[0032] Then, the fourth electric slide rail 32 is activated, moving the fourth slide plate 33 so that the support plate 39 and support block 315 are positioned below the corresponding Teflon high-temperature cloth sidewall. Next, the third electric telescopic rod 34 is activated, moving the support plate 39 and support block 315 upwards. After the top sidewall of support block 315 contacts the bottom sidewall of mounting block 213, the support block 315 and support plate 39 are about to contact the Teflon high-temperature cloth. Then, the third motor 47 is activated, rotating the corresponding second round rod 46. During the rotation of the second round rod 46, the fixing block 48 and retaining plate 49 will rotate. After the inclination angle of retaining plate 49 is the same as the inclination angle of the corresponding Teflon high-temperature cloth sidewall, the third motor 47 is deactivated. Then, the seventh electric slide rail 42 is activated, moving the seventh slide plate 43 so that the retaining plate 49 is positioned above the corresponding support block 315. Finally, the fifth electric telescopic rod 44 is activated, moving the retaining plate 49 downwards. The movement causes the retaining plate 49 to contact the Teflon high-temperature cloth. The position of the retaining plate 49 at this time is recorded. Then, the retaining plate 49 is controlled to continue moving downward, so that the bottom side wall of the Teflon high-temperature cloth contacts the top side wall of the support block 315, fixing the side wall of the Teflon high-temperature cloth. Then, the second electric telescopic rod 214 is controlled to reset, causing the clamping plate 215 to loosen the two side walls of the Teflon high-temperature cloth and release the side clamping limit. Then, the fifth electric telescopic rod 44 is slightly adjusted in the opposite direction, causing the retaining plate 49 to rise back to the previously recorded reference positioning position. At the same time, the third electric telescopic rod 34 is linked to slightly adaptively raise the support plate 39 and the support block 315. Through the bidirectional flexible limit of the top retaining plate 49 and the bottom support plate 39 and support block 315, the simulated molding state of the Teflon high-temperature cloth is locked throughout the process, ensuring that the inclination angle of the two side walls of the Teflon high-temperature cloth is consistent with the inclination angle of the corresponding mold, eliminating the problem of cloth springback and offset after clamping is released, and ensuring the stability of the measurement conditions. After the fabric shape is fully locked, the fifth electric slide rail 311 is started, driving the fifth slide plate 312 to move horizontally. The measuring plate 319 at the end of the fifth slide plate 312 moves synchronously. When the contact plate 323 on one side of the measuring plate 319 makes effective contact with the side wall of the Teflon high-temperature fabric, the contact plate 323 squeezes the detection spring 321 and the side plate 322 to transmit the force to the pressure sensor 320. After the pressure sensor 320 detects a stable and effective pressure signal, it determines that the contact plate 323 is precisely in contact with the side wall of the Teflon high-temperature fabric. Based on the movement stroke of the fifth slide plate 312 driven by the fifth electric slide rail 311, the width dimension of the Teflon high-temperature fabric in the formed state after cutting can be detected. After the width dimension is measured, the sixth electric slide rail 317 inside the fourth groove 316 of the support block 315 is activated. The sixth electric slide rail 317 drives the sixth sliding plate 318 to move horizontally, which in turn moves the corresponding measuring plate 319 and contact plate 323 until the contact plate 323 is in contact with the other side wall of the Teflon high-temperature cloth along its length. After the pressure sensor 320 detects the effective pressure signal, it determines that the length measurement point is in contact. Combining the horizontal translation stroke of the fourth electric slide rail 32, the lateral extension stroke of the fourth electric telescopic rod 314, and the feed stroke of the sixth electric slide rail 317, the effective length dimension of the Teflon high-temperature cloth in the molding state is accurately calculated. After all dimensions are collected, each electric slide rail, electric telescopic rod, and motor is reset in sequence. The cloth can be released to complete the unloading. Finally, the full-length and full-width accurate dimension measurement operation of the Teflon high-temperature cloth in the simulated V-cavity hot pressing mold assembly state is fully realized.
