Description

Technical Field

[0001] This utility model relates to the field of superconducting magnet assembly technology, specifically to an external clamp-type reversible coil reassembly machine. Background Technology

[0002] A superconducting magnet is an electromagnet made by using a type II superconductor with a high transition temperature and a particularly high critical magnetic field to create coils at low temperatures. Superconducting magnets are divided into two types: traditional cylindrical superconducting magnets and open-type superconducting magnets. Cylindrical superconducting magnets mainly consist of a core, two coils outside the core, and a frame connecting the core and the coils. Before assembly, the coils are stored in a toroidal mold. During the assembly process, both the coils before and after demolding need to be flipped. However, the coils themselves have low rigidity and are easily deformed under stress during flipping, and the external insulation material is easily damaged. Therefore, specialized equipment is needed to help flip the coils without damage. Utility Model Content

[0003] To address the shortcomings of the prior art, this invention proposes an external clamping reloading coil flipping assembly machine, which can help the coil flip without damage during the assembly of superconducting magnets.

The flipping fixture is elliptical and mounted on the front side of the frame and is provided with a pair of forward-extending clamping arms. The coil support is placed directly in front of the frame.

[0005] The coil support is surrounded by several legs, and the coil support is connected to each leg by a telescopic crossbar. A floating spring is provided around the telescopic crossbar located between the coil support and the leg.

[0007] The gripper contains a telescopic rod, a crankshaft, and two connecting rods. The crankshaft has three pins. The telescopic rod is connected to one of the pins, and the other two pins are connected to one of the clamping plates via a connecting rod. The telescopic rod drives the crankshaft to rotate, thereby controlling the approach and distance of a pair of clamping plates.

[0008] Preferably, each clamping plate has a clamping protection sensor fixedly mounted on its back and a first light-shielding plate flexibly provided. The clamping protection sensor is a reflective infrared sensor. The bottom of the first light-shielding plate is connected to a touch plate located on the front of the clamping plate. When the touch plate contacts the coil, the first light-shielding plate is pushed to the front of the clamping protection sensor to reflect the infrared beam.

[0009] Preferably, a pair of elastic blades are provided at the front and rear ends of the inner side of the gripper, and the elastic blades are elastically rotatably connected to the gripper according to a set angle.

[0010] Each elastic blade is equipped with a diameter over-limit sensor pointing to the coil on the inner wall of the adjacent gripper. The diameter over-limit sensor is a reflective infrared sensor. A second light-shielding plate is provided on the elastic blade.

[0011] When the gripper holds a coil with an excessive diameter, the coil will push the elastic blade outward, and the second light-shielding plate on the elastic blade will rotate to reflect the infrared beam directly in front of the sensor with an excessive diameter.

[0012] Preferably, the frame does not have a lifting plate, the lifting plate has a tilting flange and a tilting motor for driving the tilting flange to rotate, and the tilting clamp is installed at the front of the tilting flange.

[0013] Preferably, the flipping fixture includes a rotating arm, with a support shaft extending rearward from the middle of the rotating arm, and the support shaft is connected to the flipping flange;

[0014] Each side of the axial direction of the swing arm is equipped with a telescopic slide rod and a telescopic cylinder. A pair of clamping arms are slidably mounted on a telescopic slide rod and are driven to move closer and further away synchronously by the telescopic cylinder.

[0015] Preferably, the coil support is equipped with bottom wheels, and several legs are folded and installed on the side of the coil support.

[0016] Preferably, the coil support is provided with several horizontally extending ear plates on its periphery, and the inner end of each telescopic crossbar is horizontally rotatably mounted on one ear plate, and the outer end is rotatably connected to one support leg.

[0017] The outer ends of each support leg located on the same side of the coil support are connected to the same limiting rod by bolts.

[0018] The beneficial effects of this utility model include: the external clamping reloading coil flipping assembly machine is equipped with a flipping clamp, which can clamp the coil for lifting and vertical flipping; the coil support can float horizontally, and the coil does not need to be precisely calibrated after being placed on the coil support; when the flipping clamp holds the coil, if one clamping arm touches the coil first, it will push the coil and the coil support to move synchronously towards the other clamping arm until both clamping arms hold the coil, thus avoiding damage to the insulation material at the bottom of the coil caused by relative movement between the coil and the coil support; the external clamping reloading coil flipping assembly machine is equipped with a clamping protection sensor to prevent the clamping jaws from applying excessive pressure and causing damage to the coil; the external clamping reloading coil flipping assembly machine is equipped with a diameter over-limit sensor to prevent the coil from falling during the flipping process due to the coil diameter exceeding the clamping capacity range of the jaws, thus preventing coil damage.

Detailed Implementation

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0027] The principle of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] This utility model proposes an external clamp-type reloading coil flipping assembly machine, such as... Figure 1-3As shown, the device includes a frame 1, a flipping clamp 2, and a coil support 3. The flipping clamp 2 is vertically adjustable and is located on the front side of the frame 1, and is equipped with a pair of forward-extending clamping arms 21. The coil support 3 is placed directly in front of the frame 1. Several legs 31 are provided around the coil support 3. The coil support 3 is connected to each leg 31 by a telescopic crossbar 32, and a floating spring 33 is provided around the telescopic crossbar 32 located between the coil support 3 and the legs 31.

[0029] The external clamping reloading coil flipping assembly machine can clamp the coil 4 for lifting and vertical flipping through the flipping clamp 2. The coil support 3 can float horizontally. After the coil 4 is placed on the coil support 3, there is no need to precisely calibrate its position. When the flipping clamp 2 clamps the coil 4, if one side clamping arm 21 touches the coil 4 first, it will push the coil 4 and the coil support 3 to move towards the other side clamping arm 21 simultaneously until both sides clamp the coil 4, thus avoiding the coil 4 from moving relative to the coil support 3 and causing damage to the insulation material at the bottom of the coil 4.

[0030] In this embodiment, the front end of the clamping arm 21 is provided with a gripper 22, and the gripper 22 is provided with a vertical rail 23. A pair of clamping plates 24 are slidably arranged on the vertical rail 23. The gripper 22 is provided with a telescopic rod 25, a crankshaft 26, and two connecting rods 27. The crankshaft 26 is provided with three pins 28. The telescopic rod 25 is connected to one pin 28, and the other two pins 28 are respectively connected to one of the clamping plates 24 through a connecting rod 27. The telescopic rod 25 drives the crankshaft 26 to rotate to control the pair of clamping plates 24 to approach and move away. The telescopic rod 25 is driven by a cylinder. When the telescopic rod 25 extends, the crankshaft 26 drives the two connecting rods 27 to move closer together, thereby causing the clamping plates 24 to move closer together to clamp the coil 4. When the telescopic rod 25 retracts, the crankshaft 26 drives the two connecting rods 27 to move away, thereby causing the clamping plates 24 to release the coil 4.

[0031] In this embodiment, a clamping protection sensor 51 is fixedly mounted on the back of each clamping plate 24, and a first light-shielding plate 52 is elastically provided. The clamping protection sensor 51 is a reflective infrared sensor. The bottom of the first light-shielding plate 52 is connected to a contact plate 53 located on the front of the clamping plate 24. When the contact plate 53 contacts the coil 4, the first light-shielding plate 52 is pushed to the front of the clamping protection sensor 51 to reflect the infrared beam. The external clamping reloading coil flipping assembly machine controls the cylinder of the telescopic rod 25 through the clamping protection sensor 51. When the infrared beam emitted by the clamping protection sensor 51 itself is reflected and received, a control signal is sent to stop the cylinder from working, so as to avoid the clamping claw 22 applying too much pressure and causing damage to the coil 4.

[0032] In this embodiment, a pair of elastic blades 61 are arranged opposite each other at the front and rear ends of the inner side of the gripper 22. The elastic blades 61 are elastically rotatably connected to the gripper 22 according to a set angle. The inner wall of the gripper 22 adjacent to each elastic blade 61 is provided with a diameter over-limit sensor 62 pointing to the coil 4. The diameter over-limit sensor 62 is a reflective infrared sensor. A second light-shielding plate 63 is provided on the elastic blade 61. When the gripper 22 clamps the coil 4 with an over-limit diameter, the coil 4 will push the elastic blade 61 outward. The second light-shielding plate 63 located on the elastic blade 61 will rotate to reflect the infrared beam directly in front of the diameter over-limit sensor 62. The diameter over-limit sensor 62 can prevent the coil 4 from falling off during the flipping process because the diameter of the coil 4 exceeds the clamping capacity of the gripper 22. When the infrared beam emitted by the diameter over-limit sensor 62 itself is reflected and received, it will send a signal to stop the operation of the external clamping reloading coil flipping assembly machine. At this time, it is necessary to modify the parameters or replace the gripper 22 that is compatible with the coil 4 before flipping.

[0033] In this embodiment, the frame 1 does not have a lifting plate 7. The lifting plate 7 has a flip flange 71 and a flip motor 72 for driving the flip flange 71 to rotate. The flip clamp 2 is installed at the front of the flip flange 71. The flip clamp 2 includes a rotating arm 29, with a support shaft 291 extending rearward from the middle of the rotating arm 29. The support shaft 291 is connected to the flip flange 71. Each side of the rotating arm 29 in the axial direction is provided with a telescopic slide rod 211 and a telescopic cylinder 212. A pair of clamping arms 21 are slidably mounted on one telescopic slide rod 211 and are driven to move synchronously closer and further away by the telescopic cylinder 212.

[0034] In this embodiment, the coil support 3 is equipped with bottom wheels, and several support legs 31 are folded and installed on the side of the coil support 3. When the support is retracted, the coil support 3 can be pushed to move. After the coil support 3 is positioned in front of the frame 1, the support is erected to prevent movement. The left, right and rear sides of the coil support 3 are each provided with two support legs 31. Around the coil support 3, corresponding to each support leg 31, there is a horizontally extending ear plate 34. The inner end of each telescopic crossbar 32 is horizontally rotatably mounted on the corresponding ear plate 34, and the outer end is rotatably connected to the corresponding support leg 31. The outer side of the two support legs 31 on each side is provided with a limiting rod 35. The limiting rod 35 is fixedly connected to the support leg 31 by bolts, which can enhance the stability of the support leg 31.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
