Description
Technical Field
[0001] This invention relates to the technical field of magnetic resonance component processing and manufacturing equipment, specifically to a cylindrical gradient coil processing equipment. Background Technology
[0002] As a cutting-edge technology, magnetic resonance imaging (MRI) equipment has been applied to various high-precision fields, including but not limited to medical diagnosis, materials structure research, quantum computing, and non-destructive testing.
[0003] In magnetic resonance imaging (MRI) technology, extremely high precision is required for both the workpieces and the equipment used. To ensure the workpieces remain in good condition and are not easily damaged during subsequent use and operation, high standards are demanded in the initial material selection and processing. While material quality is generally easy to control, existing conventional processing equipment struggles to achieve the required precision, particularly in pressure control and thickness control during sheet forming. This leads to a series of problems in subsequent grooving and winding assembly due to insufficient precision, affecting the performance of the superconducting equipment. Therefore, a cylindrical gradient coil processing device is urgently needed to solve these problems. Summary of the Invention
[0004] The purpose of this invention is to provide a cylindrical gradient coil processing device to overcome the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A cylindrical gradient coil processing device includes two horizontally arranged pads. Two vertically arranged machine body plates are fixedly connected to the upper ends of the pads. A horizontally arranged main shaft is positioned between the two machine body plates. A main roller is fixedly sleeved on the main shaft. Rangefinders are fixedly installed on the upper ends of the two pads corresponding to the positions of the main rollers. Sliding blocks are provided on both sides of the main shaft. A groove matching the sliding block is provided through the side wall of the machine body plate. The sliding block is slidably connected to the inner side wall of the groove. Pressure sensors are fixedly connected to the upper ends of both sliding blocks. Two horizontally arranged secondary shafts are provided below the main roller. Secondary rollers are fixedly sleeved on the secondary shafts. Cranks are rotatably sleeved at both ends of the secondary shafts through the machine body plates. Fixed plates are provided on opposite sides of the two machine body plates. The fixed plates are fixedly connected to the upper ends of the pads. The lower ends of the cranks on both sides are rotatably connected to the side walls of the fixed plates.
[0007] By adopting the above technical solution, the sliding characteristic of the sliding blocks on both sides within the groove allows for timely detection of changes in the position of the main shaft and main roller via pressure sensors and pressure changes on the top surface of the groove. This enables real-time monitoring of the pressure between the main roller and auxiliary roller during plate rolling, ensuring uniform stress on all parts of the plate. Changes in pressure are immediately detected and displayed by the pressure sensors. Simultaneously, by setting up a rangefinder, the distance between the main roller and the rangefinder is measured before processing. Changes in this distance during plate processing are then used to detect the thickness of the plate, allowing for comprehensive monitoring of the processing work and improving processing accuracy. The combination of the rangefinder and the pressure tester further enhances the precision of plate rolling, meeting the requirements of high-precision machining.
[0008] Preferably, a horizontally arranged guide rail is provided between the two pads.
[0009] By adopting the above technical solution, the guide rail is used to assist in the production and manufacturing of the plate rolling machine.
[0010] Preferably, one of the body plates is provided with a pawl on the side near the main shaft, and the other body plate is provided with an abutment on the side near the main shaft. The main shaft is located between the pawl and the abutment, and the pawl and the abutment are respectively fixedly connected to the sliding blocks on both sides.
[0011] By adopting the above technical solution, the main shaft is fixed by the jaws and the contact head. At the same time, the sliding blocks on both sides can move simultaneously with the main shaft when it moves vertically. With the pressure sensor at the top, the pressure can be monitored in real time to avoid uneven pressure on the material processed by the plate rolling machine due to insufficient pressure, thus ensuring the accuracy of plate rolling and the uniform material distribution in each position of the subsequent product.
[0012] Preferably, a hydraulic cylinder is fixedly installed on the upper end of both machine body plates. The output end of the hydraulic cylinder passes through the side wall of the machine body plate and extends to the inside of the slide groove. The output end of the hydraulic cylinder is fixedly connected to the upper end of the sliding block.
[0013] By adopting the above technical solution, the position of the sliding block is controlled by the hydraulic cylinder before processing. The main shaft and the main roller are synchronized by the up and down movement of the sliding block. In this way, the pressure value between the main roller and the auxiliary roller can be preset before processing. With the use of a pressure sensor, the pressure control between the main roller and the auxiliary roller during processing can be more accurate.
[0014] Preferably, arc-shaped grooves are provided on the side walls of the two body plates corresponding to the positions of the two secondary shafts, and the secondary shafts are provided through the arc-shaped grooves.
[0015] By adopting the above technical solution, the movement of the secondary shaft is restricted by setting the arc groove. In addition to the rotation of the secondary shaft itself, the distance and direction of the secondary shaft's left and right movement can also be restricted to a certain extent, making the adjustment of the secondary shaft more accurate and less prone to errors.
[0016] Preferably, a drive motor is fixedly installed on the upper end of the pad, the output end of the drive motor is rotatably connected to the side wall of the fixed plate, and a drive wheel is coaxially fixedly sleeved on the output end of the drive motor. A transmission wheel is fixedly sleeved on the end of each of the two secondary shafts near the drive wheel, and the two transmission wheels mesh with the drive wheel.
[0017] By adopting the above technical solution, the drive motor output drives the drive wheel to rotate and mesh with the transmission wheels on both sides, thereby driving the transmission wheels on both sides and the secondary shaft to rotate. Through the rotation of the secondary shaft and the secondary roller, and in conjunction with the pressure provided by the main roller, the sheet material can be extruded and shaped.
[0018] Preferably, the lower ends of the two cranks away from the drive motor rotate through the fixed plate and are fixedly sleeved with mating wheels. An adjustment motor is fixedly installed on the upper end of the pad, and the output end of the adjustment motor is coaxially and fixedly connected to one of the mating wheels.
[0019] By adopting the above technical solution, the mating wheels fixedly sleeved at the lower ends of the two cranks can simultaneously drive the lower ends of the two cranks to rotate after meshing with the adjusting wheel. When the cranks rotate, the two auxiliary shafts can be driven to adjust their positions within the arc-shaped groove. The distance between the auxiliary rollers and the main rollers can be adjusted by changing the position of the auxiliary rollers. Thus, when facing materials of different processing thicknesses and different processing requirements, the position of the auxiliary rollers can be freely adjusted while maintaining the same distance between the auxiliary rollers on both sides and the main rollers, thereby improving the adjustment efficiency and accuracy of the roller spacing.
[0020] In the above technical solution, the beneficial effects of the present invention are:
[0021] This cylindrical gradient coil processing equipment is equipped with sliding blocks and pressure sensors. Before processing, the position of the sliding blocks is controlled by a hydraulic cylinder. The up-and-down movement of the sliding blocks synchronizes the main shaft and the main roller. The pressure value between the main roller and the auxiliary roller can be preset before processing. With the use of pressure sensors, the pressure control between the main roller and the auxiliary roller can be more accurate during processing. When the main roller moves up and down during processing, it can be reflected to the pressure sensor in real time through the sliding blocks on both sides. The pressure sensor can then reflect and display the pressure changes on the plate in a timely manner, so as to process and produce plates that require precise pressure. At the same time, it is convenient for the staff to adjust the device in time when errors occur, improve the accuracy of the device during production, and ensure the high precision of the output products.
[0022] By setting up cranks and mating wheels, the rotation of the mating wheels and cranks can be achieved by adjusting the motor drive. The two mating wheels mesh with each other, causing the cranks on both sides to rotate simultaneously. This, in turn, adjusts the two secondary shafts to open or close along the arc-shaped groove, thereby adjusting the distance between the secondary roller and the main roller. By adjusting the distance between the secondary roller and the main roller, it can adapt to plates of different thicknesses and materials, making the overall device more adaptable to various production requirements while ensuring processing accuracy.

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0033] Please see Figure 1-6 The cylindrical gradient coil processing equipment provided in this embodiment of the invention includes two horizontally arranged pads 1. Two numerically arranged machine body plates 2 are fixedly connected to the upper end of the pads 1. A horizontally arranged main shaft 3 is arranged between the two machine body plates 2. A main roller 4 is fixedly sleeved on the main shaft 3. A rangefinder 5 is fixedly installed on the upper end of the two pads 1 corresponding to the position of the main roller 4. Before processing, the distance between the main roller 4 and the rangefinder 5 is measured by the rangefinder 5. Then, during the processing of the sheet metal, the thickness of the sheet metal can be detected by measuring the change in distance, thereby improving the processing accuracy by monitoring the processing work in all aspects.
[0034] In this invention, sliding blocks 6 are provided on both sides of the main shaft 3, and a sliding groove 7 matching the sliding block 6 is provided through the side wall of the machine body plate 2. The sliding block 6 is slidably connected to the inner side wall of the sliding groove 7, and pressure sensors 8 are fixedly connected to the upper ends of the two sliding blocks 6. Two horizontally arranged secondary shafts 9 are provided on the lower side of the main roller 4. A secondary roller 22 is fixedly sleeved on the secondary shaft 9. Both ends of the secondary shaft 9 pass through the machine body plate 2 and are rotatably sleeved with cranks 10. A fixing plate 11 is provided on the opposite side of the two machine body plates 2. The fixing plate 11 is fixedly connected to the upper end of the pad plate 1, and the lower ends of the cranks 10 on both sides are rotatably connected to the side wall of the fixing plate 11.
[0035] In this invention, the sliding characteristic of the sliding blocks 6 on both sides that can slide within the groove 7 during processing allows the main shaft 3 and main roller 4 to change positions. This is detected in time by the pressure sensor 8 and the pressure change on the top surface of the groove 7. Thus, when the main roller 4 and auxiliary roller 22 are rolling the plate, the pressure between the main roller 4 and auxiliary roller 22 can be monitored in real time, ensuring uniform stress on all parts of the plate during rolling. When the pressure changes, the pressure sensor 8 can react and display the change immediately. At the same time, the rangefinder 5, in conjunction with the pressure tester, can improve the accuracy of plate rolling processing to meet the requirements of high-precision operation.
[0036] In this invention, a horizontally arranged guide rail 12 is provided between the two pads 1, and the guide rail 12 is used to assist the production and manufacturing of the plate rolling machine.
[0037] In this invention, one of the machine body plates 2 is provided with a chuck 13 on the side near the main shaft 3, and the other machine body plate 2 is provided with an abutment head 14 on the side near the main shaft 3. The main shaft 3 is located between the chuck 13 and the abutment head 14, and the chuck 13 and the abutment head 14 are respectively fixedly connected to the sliding blocks 6 on both sides. The main shaft 3 is fixed by the chuck 13 and the abutment head 14. At the same time, the sliding blocks 6 on both sides can move simultaneously with the main shaft 3 when it moves vertically. With the setting of the pressure sensor 8 at the upper end, the pressure can be monitored in real time to avoid uneven pressure of the material processed by the plate rolling machine due to insufficient pressure, thus ensuring the accuracy of plate rolling and the uniform material distribution at each position of the subsequent product.
[0038] In this invention, hydraulic cylinders 15 are fixedly installed on the upper ends of both machine body plates 2. The output end of the hydraulic cylinder 15 passes through the upper side wall of the machine body plate 2 and extends to the inner side of the slide groove 7. The output end of the hydraulic cylinder 15 is fixedly connected to the upper end of the sliding block 6. Before processing, the position of the sliding block 6 is controlled by the hydraulic cylinder 15. The main shaft 3 and the main roller 4 are synchronized by the up and down movement of the sliding block 6. Thus, the pressure value between the main roller 4 and the auxiliary roller 22 can be preset before processing. With the use of the pressure sensor 8, the pressure control between the main roller 4 and the auxiliary roller 22 during processing can be more accurate.
[0039] In this invention, arc-shaped grooves 16 are provided on the side walls of the two body plates 2 corresponding to the positions of the two secondary shafts 9. The secondary shafts 9 are set through the arc-shaped grooves 16. The movement of the secondary shafts 9 is restricted by the setting of the arc-shaped grooves 16. In addition to the rotation of the secondary shafts 9 themselves, the distance and direction of the left and right movement of the secondary shafts 9 can also be restricted to a certain extent, so that the adjustment of the secondary shafts 9 is more accurate and less prone to errors.
[0040] In this invention, a drive motor 17 is fixedly installed on the upper end of the pad 1. The output end of the drive motor 17 is rotatably connected to the side wall of the fixed plate 11, and a drive wheel 19 is coaxially fixedly sleeved on the output end of the drive motor 17. Transmission wheels 18 are fixedly sleeved on the ends of the two secondary shafts 9 near the drive wheels 19. The two transmission wheels 18 and the drive wheels 19 mesh with each other. The drive wheel 19 is driven to rotate by the output end of the drive motor 17 to mesh with the transmission wheels 18 on both sides, thereby driving the transmission wheels 18 on both sides and the secondary shafts 9 to rotate. Through the rotation of the secondary shafts 9 and the secondary rollers 22, and in conjunction with the pressure provided by the main roller 4, the sheet material can be extruded and formed.
[0041] In this invention, the lower ends of the two cranks 10, which are far from the drive motor 17, rotate through the fixed plate 11 and are fixedly sleeved with mating wheels 20. An adjusting motor 21 is fixedly installed on the upper end of the pad 1. The output end of the adjusting motor 21 is coaxially fixedly connected to one of the mating wheels 20. The mating wheels 20, which are fixedly sleeved on the lower ends of the two cranks 10, can simultaneously drive the lower ends of the two cranks 10 to rotate through the output end of the adjusting motor 21 after meshing with the adjusting wheel. When the cranks 10 rotate, they can drive the two auxiliary shafts 9 to adjust their positions in the arc groove 16. The distance between the auxiliary roller 22 and the main roller 4 can be adjusted by changing the position of the auxiliary roller 22. Thus, when facing materials with different processing thicknesses and different processing requirements, the position of the auxiliary roller 22 can be freely adjusted and the distance between the auxiliary rollers 22 and the main roller 4 on both sides can be kept the same, thereby improving the adjustment efficiency and accuracy of the roller spacing.
[0042] Before processing, the rotation of the output end of motor 21 drives the two mating wheels 20 to rotate. When the mating wheels 20 and crank 10 rotate, they drive the secondary shaft 9 to move within the arc groove 16. The movement of the secondary shafts 9 on both sides adjusts the distance between the secondary roller 22 and the main roller 4. After the distance is adjusted, the sliding block 6 is pushed downward by the hydraulic cylinder 15. The pressure and distance are kept constant by the assistance of the rangefinder 5 and the numerical value of the pressure tester. Once the accuracy is met, the drive motor 17 is started and the plate is placed in. At this time, the output end of the drive motor 17 drives the drive wheel 19 to rotate, which meshes with the transmission wheel 18, thereby driving the two secondary shafts 9 and the secondary roller 22 to rotate, thus processing the plate. At the same time, the rangefinder 5 is used to drive the secondary roller 22 to rotate, thus processing the plate. The distance gauge 5 is set to know the specific thickness of the board. The pressure value between the main roller 4 and the auxiliary roller 22 is known through the value of the pressure sensor 8 to ensure the accuracy of the board processing. After the adjustment is completed, the drive motor 17 is started. The output end of the drive motor 17 drives the drive wheel 19 to rotate and mesh with the transmission wheel 18. The transmission wheel 18 drives the auxiliary shaft 9 to rotate. The rotation of the auxiliary shaft 9 and the auxiliary roller 22 can process and shape the board. Once the main roller 4 moves vertically during the processing, the distance between the pressure sensor 8 and the top of the slide 7 will change, thereby changing the pressure value. The position of the main roller 4 can be changed in time to adjust the pressure between the main roller 4 and the auxiliary roller 22, so that the pressure on the board during the processing remains uniform.
