Description

Technical Field

[0001] This invention relates to the field of diameter reduction device technology, and in particular to an openable CS internal coil diameter reduction device. Background Technology

[0002] In large tokamak devices, the central solenoid (CS) coil is usually made of cable-in-conduit conductor. To ensure the filler ratio and dimensional accuracy of the coil, the conductor needs to be rolled and shaped before winding.

[0003] In existing technologies, conductor diameter reduction devices mainly consist of a frame, multiple sets of rollers evenly distributed along the circumference, and an adjustment mechanism. The clamping and diameter reduction of conductors of different specifications are achieved by changing the radial spacing between the rollers. The roller spacing is often adjusted using a radial feed structure, such as manual screw adjustment or a hydraulic cylinder directly driving the roller seat to move along the radial guide rail. However, this radial adjustment method has the following shortcomings in practical applications: First, the radial guide rail and drive components require a large radial space, resulting in a large overall size of the device, making it difficult to arrange flexibly in space-constrained coil winding stations; Second, when clamping conductors, it is necessary to adjust each one individually or use a complex linkage mechanism to move multiple rollers synchronously, resulting in slow opening and closing speeds, making it difficult to meet the production cycle of rapid conductor loading, clamping, and unloading, leading to long auxiliary time and affecting overall processing efficiency; Third, the radial guide rail is prone to uneven force during long-term use, leading to a decrease in guiding accuracy, causing rollers to jam and resulting in unstable clamping and positioning accuracy; Fourth, when the conductor is fed into the diameter reduction device, it often needs to be accurately aligned with the coil winding position and stably guided axially, but most existing diameter reduction devices lack reliable alignment movement and axial guiding mechanisms, causing the conductor to easily deviate and move, affecting the coaxiality of the diameter reduction and the final coil forming quality.

[0004] Therefore, how to design a compact, high-precision clamping, and good coil forming effect openable CS internal coil diameter reduction device has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This invention provides an openable CS internal coil diameter reduction device, which solves the technical problems of existing coil diameter reduction devices, such as limited clamping size, low clamping accuracy, slow clamping speed and lack of alignment adjustment mechanism.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an opening and closing type CS internal coil diameter reduction device, comprising: a front moving ring, multiple fixed seats, multiple roller frames and multiple telescopic rods, wherein the multiple fixed seats are fixedly fixed on the front moving ring at intervals along the circumferential direction; the multiple roller frames are rotatably connected to the multiple fixed seats by rotating shafts, and the multiple rotating shafts are arranged in the tangential direction of the corresponding fixed seat position; each of the multiple roller frames is rotatably connected to a roller, and a clamping area is defined between the multiple rollers; the multiple telescopic rods are respectively arranged behind the multiple roller frames and fixed at intervals on the front moving ring, and their telescopic ends reciprocate along the axial direction of the front moving ring and are respectively fixed on the multiple roller frames to push the multiple roller frames to open and close, so that the multiple rollers move away from each other to release the conductor or move closer to each other to clamp the conductor.

[0007] The beneficial effects of this invention are as follows: by rotating the roller frame onto the fixed base via a rotating shaft and arranging the rotating shaft along the tangential direction of the corresponding fixed base position, the roller frame is driven to swing by the reciprocating motion of the telescopic rod along the front moving ring axis. This transforms the traditional radial guide rail feeding clamping method into an axial drive swing opening and closing method, enabling multiple rollers to synchronously and quickly move away from each other to open the clamping area, or synchronously and quickly move closer to each other to clamp the conductor. This facilitates the insertion, clamping, and release of the conductor, significantly shortens auxiliary time, and effectively improves processing efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, it also includes a rear fixed plate, an internal gear ring, multiple commutators, and a drive motor. The rear fixed plate is spaced behind the front moving ring and has a rear through hole opposite to the inner hole of the front moving ring. The internal gear ring is rotatably connected between the front moving ring and the rear fixed plate. The multiple commutators are respectively arranged on one side of the multiple fixed seats and fixed to the front moving ring at intervals. The output shafts of the multiple commutators are respectively connected to the multiple rollers through gears, chains, sprockets, or belts, and each of their input shafts has a driven gear fixed to mesh with the internal gear ring. The drive motor is fixed on the rear fixed plate and has a driving gear fixed on its output shaft. The driving gear meshes with the internal gear ring to drive the multiple rollers to rotate.

[0010] The further beneficial effects of adopting the above are as follows: by driving the drive motor to drive the driving gear, the driving gear to drive the internal gear ring, and then the internal gear ring to synchronously drive the driven gears on the input shafts of each commutator, the power is transmitted to each roller through the commutator, realizing the transmission layout of a single motor driving multiple rollers to rotate synchronously, replacing the traditional independent motor drive for each group of rollers or complex multi-stage gear and sprocket transmission, making the structure more compact, the transmission chain shorter, the synchronization better, effectively ensuring that the rotation speed of each roller is consistent, and avoiding conductor surface damage or uneven diameter reduction caused by speed difference.

[0011] Furthermore, it also includes a first movable frame, a second movable frame, a lead screw, a slider, and a first movable motor. The front moving ring rotates on the first movable frame, and the rear fixed plate is fixed on the first movable frame. The second movable frame is located below the first movable frame. The lead screw is rotatably connected to the second movable frame along an axis perpendicular to the front moving ring. The slider has a threaded hole and is threadedly connected to the lead screw. The first movable frame is fixed on the slider. The first movable motor is fixed on the second movable frame, and its output shaft is drivenly connected to the lead screw to drive the first movable frame to move.

[0012] The further beneficial effects of adopting the above are as follows: by setting up a centering motor, a lead screw, a slider, and a first moving frame, the centering motor is fixed on the second moving frame and its output shaft is connected to the lead screw drive. The lead screw is rotatably connected to the second moving frame and arranged in a direction perpendicular to the axis of the front moving ring. The first moving frame is threadedly connected to the lead screw through the slider, so that when the centering motor drives the lead screw to rotate, the first moving frame can drive the front moving ring and roller as a whole to move in a direction perpendicular to the axis of the front moving ring, thereby flexibly adjusting the position of the clamping area, so that the clamping area can automatically center with the conductor to be processed, effectively solving the problem of skewing and movement caused by the deviation of the conductor feeding position, ensuring the coaxiality of the diameter reduction, and thus improving the coil forming quality.

[0013] Furthermore, it also includes a lower rack, a base, and a second moving motor. The base is located below the second moving frame. The lower rack is arranged along the length direction perpendicular to the lead screw and fixed on the base. The second moving motor is fixed on the second moving frame and a lower gear is fixed on its output shaft. The lower gear meshes with the lower rack to drive the second moving frame to move.

[0014] The further beneficial effects of the above are as follows: by setting a lower rack, a base, and a second moving motor, the lower rack is fixed on the base along the length direction perpendicular to the lead screw, and the second moving motor is fixed on the second moving frame, with the lower gear on its output shaft meshing with the lower rack. When the second moving motor drives the lower gear to rotate, the second moving frame can move as a whole along the base direction, thereby driving the rollers and clamping area to feed along the conductor axis direction, realizing continuous diameter reduction rolling processing of the entire length of the conductor.

[0015] Furthermore, it also includes a guide rail, an upper rack, a guide motor, and multiple guides. The guide rail is arranged axially above the first movable frame along the front moving ring. The top end of the first movable frame slides on the guide rail. The upper rack is fixed on the guide rail along its length. Multiple guides are fixed at intervals on the guide rail along its length and each guide has a guide hole for the coil to pass through. The guide motor is fixed on the first movable frame and has an upper gear fixed on it. The upper gear meshes with the upper rack to drive the multiple guides to move.

[0016] The further beneficial effects of the above are as follows: by setting up a guide rail, an upper rack, a guide motor, and multiple guides, the guide rail is arranged axially above the first moving frame along the front moving ring. Multiple guides are fixed at intervals along the length of the guide rail and each has a guide hole for the conductor to pass through. The guide motor meshes with the upper rack fixed on the guide rail through the upper gear, driving the guide rail to move each guide along the axial direction. Thus, it can provide stable axial guidance support for the conductor before it enters the clamping area and after the diameter reduction forming, effectively preventing the conductor from deflecting and moving during the feeding and feeding process, and further ensuring the coaxiality of the diameter reduction and the quality of the coil forming.

[0017] Furthermore, it also includes a manual fine-tuning component, which includes a geared motor, a manual wheel, and a fine-tuning wheel. The outer side of the front moving ring has multiple fine-tuning teeth. The geared motor is fixed on the first moving frame. The manual wheel is drivenly connected to the input shaft of the geared motor. The fine-tuning wheel is fixed to the output shaft of the geared motor and meshes with the multiple fine-tuning teeth on the outer side of the front moving ring to fine-tune the position of the front moving ring.
