Description

Technical Field

[0001] This utility model relates to the field of testing cylindrical carbon fiber thermal insulation materials, and in particular to a diameter measuring device for cylindrical carbon fiber thermal insulation materials. Background Technology

[0002] Cylindrical carbon fiber is a composite material reinforced with carbon fiber, possessing excellent mechanical properties and being lightweight and high-strength. This material is widely used in aerospace, sports and leisure, automotive, wind turbine blades, fuel cells, power cables, pressure vessels, and other fields.

[0003] Current methods for measuring the diameter of cylindrical carbon fibers in the industry mainly employ contact and non-contact measurement methods. Contact measurement methods often use mechanical instruments such as vernier calipers, dial indicators, and coordinate measuring machines. However, these methods tend to have large measurement errors for large workpieces or workpieces with high precision requirements. Some workpieces have coatings, and there is a risk of scratching the coating when the measuring tool comes into contact with the workpiece. Non-contact measurement methods often include photoelectric technology, laser scanning, and microscopy. These methods are mainly used for measuring high-precision workpieces and can reduce contact with the workpiece. However, the equipment used in these methods is too expensive, and the equipment has high requirements for the surrounding environment. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a diameter measuring device for cylindrical carbon fiber insulation materials, which solves the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A diameter measuring device for cylindrical carbon fiber insulation material includes a base, a turntable, and a workpiece to be measured. The turntable is rotatably mounted on the base, and the workpiece to be measured is mounted on the top of the turntable. A wide slot is provided on the top of the base, and a drive motor is installed in the wide slot. A connector is installed on the output shaft of the drive motor, and the drive motor is fixedly connected to the turntable through the connector. The top of the turntable is provided with a mounting assembly for limiting and fixing the workpiece to be measured. Each support leg on the top of the base is fixed with a column, and an electric slide rail is installed on two adjacent side walls of each column. A measuring light curtain is installed between two opposing electric slide rails.

[0007] The measuring light curtain includes two light curtain transmitters and two light curtain receivers, which are arranged opposite to each other and are raised and lowered synchronously via the electric slide rail.

[0008] Preferably, the mounting assembly includes a first bevel gear, several second bevel gears, and several lead screws. A storage slot is provided at the top of the turntable. The first bevel gear and each of the second bevel gears are rotatably disposed within the storage slot. A wide slot is provided at the bottom of the storage slot, and a second drive motor is installed within the wide slot. The output shaft of the second drive motor is fixed to the first bevel gear, and each second bevel gear meshes with the first bevel gear. Several connecting slots are also provided at the top of the turntable, and each lead screw is rotatably disposed within a connecting slot. One end of each lead screw passes through the connecting slot and is disposed within the storage slot. One end of the lead screw is fixedly connected to the second bevel gear. A slider is slidably disposed within the connecting slot, and the slider is threadedly engaged with the lead screw. A rubber clamp is fixed to the top of each slider.

[0009] Preferably, the connector is a square locking block, and a square groove is provided at the bottom of the turntable, with one end of the square locking block engaging inside the square groove.

[0020] See Figures 1 to 5 As shown, a diameter measuring device for cylindrical carbon fiber insulation material includes a base 1, a turntable 2, and a workpiece 3 to be measured. The turntable 2 is rotatably mounted on the base 1, and the workpiece 3 to be measured is mounted on the top of the turntable 2. The top of the turntable is provided with a mounting component 7 for limiting and fixing the workpiece 3 to be measured. When it is necessary to measure the diameter of the workpiece to be measured, the workpiece 3 to be measured can be placed on the turntable 2 first. By activating the mounting component 7, the workpiece 3 to be measured can be installed and limited to prevent displacement of the workpiece 3 during subsequent measurement.

[0021] The mounting assembly 7 includes a first bevel gear 12, several second bevel gears 13, and several lead screws 14. The top of the turntable 2 has a storage slot 15. The first bevel gear 12 and each second bevel gear 13 are rotatably mounted in the storage slot 15. The bottom of the storage slot 15 has a wide slot 16. A second drive motor 17 is installed in the wide slot 16. The output shaft of the second drive motor 17 is fixed to the first bevel gear 12. Each second bevel gear 13 meshes with the first bevel gear 12. The top of the turntable 2 also has several connecting slots 18. Each lead screw 14 is rotatably mounted in the connecting slot 18. One end of the lead screw 14 passes through the connecting slot 18 and is mounted in the storage slot 15. One end of the lead screw 14 is fixedly connected to the second bevel gear 13. A slider 19 is also slidably mounted in the connecting slot 18. The slider 19 is threadedly engaged with the lead screw 14. A rubber clamp 20 is fixed to the top of each slider 19.

[0022] During the installation of the workpiece 3, each rubber clamp 20 is located inside the workpiece 3. During the clamping and installation of the workpiece 3, the second drive motor 17 starts, driving the first bevel gear 12 to rotate. The second drive motor 17 is a servo motor, which allows for better control of the rotation of the first bevel gear 12. The rotation of the first bevel gear 12 drives the meshing bevel gears 13 to rotate, which in turn drives the lead screw 14 to rotate. The rotation of the lead screw 14 causes the slider 19, which is threadedly engaged with it, to rotate within the connecting groove 18. The slider 19 is limited by the connecting groove 18, causing the rotational connection to become a sliding connection. The slider 19 will drive the rubber clamp 20 to move together. When the rubber clamp 20 contacts the inner wall of the workpiece 3 to be tested, the drive motor 17 will shut off. The deformable principle of the rubber clamp 20 is used to prevent excessive force from being applied to the workpiece 3 to be tested, thus preventing damage to the workpiece 3. The clamping of the rubber also prevents damage to the workpiece 3 to be tested.

[0023] Each support leg on the top of the base 1 is fixed with a column 8. Electric slide rails 9 are installed on the two adjacent side walls of each column 8. A measuring light curtain is installed between the two opposing electric slide rails 9. The measuring light curtain includes two light curtain transmitters 10 and two light curtain receivers 11, which are positioned opposite each other. The light curtain transmitters 10 and light curtain receivers 11 are synchronously raised and lowered via the electric slide rails 9. When the workpiece 3 to be measured is installed, the light curtain transmitters 10 and light curtain receivers 11 are activated. The light curtain transmitters 10 emit infrared beams, which form a light curtain. The light curtain receivers 11 are responsible for receiving and analyzing the beams. When the workpiece enters the beam area, it blocks part of the beam, thus changing the intensity of the beam received by the light curtain receivers 11. When the light curtain receiver 11 receives light beams of different intensities, it triggers a corresponding signal processing mechanism to convert the light signal into an electrical signal. The light curtain receiver 11, the light curtain transmitter 10, and the electric slide rail 9 are all connected to an external controller. The controller has a processor inside. The controller controls the two opposing light curtain receivers 11 and light curtain transmitters 10 to move in tandem. The corresponding electric slide rails 9 are also activated in tandem to ensure the smooth lifting and lowering of the light curtain receivers 11 and light curtain transmitters 10. The light curtain receivers 11 and light curtain transmitters 10 move up and down through the electric slide rails 9, so that the entire workpiece 3 to be measured can be scanned and the data can be transmitted to the controller. The controller processes and analyzes the received data and calculates the size information of the object, thereby achieving non-contact measurement.

[0024] An extension block 23 is fixed on each of the two opposite side walls of the base 1. A column 24 is fixedly installed on the top of the extension block 23. A 3D scanner 25 is installed on each of the opposite surfaces of the two columns 24. A gap is left between the bottom of the 3D scanner 25 and the base 1. The gap of the 3D scanner 25 is the same as the height of the turntable 2 to prevent the turntable 2 from interfering with the scanning of the 3D scanner 25. After the scanning of the light curtain size is completed, the light curtain receiver 11 and the light curtain transmitter 10 corresponding to the 3D scanner 25 will be lowered to the bottom via the electric slide rail 9. The height of the light curtain receiver 11 and the light curtain transmitter 10 is less than the height of the turntable 2 to prevent subsequent interference with the operation of the 3D scanner 25.

[0025] The top of the base 1 has a wide slot 4, in which a drive motor 5 is installed. A connector 6 is installed on the output shaft of the drive motor 5, and the drive motor 5 is fixedly connected to the turntable 2 through the connector 6. The 3D scanner 25 is prior art, so its structure and principle will not be further disclosed in this application. When the 3D scanner 25 is used, the drive motor 5 will start, and the output shaft of the drive motor 5 can drive the turntable 2 to rotate through the connector 6. The turntable 2 rotates one revolution, so that the overall appearance of the workpiece can be scanned by the 3D scanner 25, capturing the three-dimensional shape of the object and converting it into a digital model. It can be compared with its original drawing to detect whether there is a large difference in size. The 3D scanner 25 also adopts an external controller for operation control. The controller can be programmed to set multiple scanning modes.

[0026] The top of the base 1 is also provided with an annular groove 21, and the bottom of the turntable 2 is equipped with multiple rollers 22. Each roller 22 is rotatably arranged in the annular groove 21. When the turntable 2 rotates, it will drive each roller 22 to rotate in the annular groove 21. The arrangement of the rollers 22 can support the turntable 2 and reduce the friction experienced by the turntable 2 when it rotates.

[0027] The connector 6 is a square clip. The bottom of the turntable 2 has a square groove. One end of the square clip is inserted into the square groove. The simple connection between the connector 6 and the turntable 2 facilitates the disassembly of the turntable 2, allowing the turntable 2 to be changed to different sizes according to the size of the workpiece 3 to be measured.
