Description

Technical Field

[0001] The invention relates to the technical field of magnetic coupler testing, in particular to a static magnetic coupler torque testing device. Background Art

[0002] At present, magnetic couplings have been widely used in many industrial fields. They transmit torque through magnetic fields and have the advantages of contactless transmission, no need for lubrication, and vibration isolation. However, there is a lack of efficient and accurate torque testing devices for performance evaluation and quality inspection of magnetic couplings.

[0003] The existing torque test device requires a complex installation and debugging process during use, has high technical requirements for operators, and has low test efficiency. In addition, since the internal and external magnets of the magnetic coupler need to be installed and fixed to the torque test device respectively during the test, the operator needs to independently disassemble and install the internal and external magnets of each magnetic coupler. The traditional installation method requires the operator to locate the internal and external magnets and then clamp them with a clamp. Since multiple groups of magnetic couplers need to be tested for torque, the operator needs to manually load and unload each group of magnetic couplers after testing them during the test. This process is extremely cumbersome and requires the operator to complete loading, testing, recording and unloading in sequence, with a low degree of automation.

[0004] Although there is currently an electrical clamping method to position and clamp the internal and external magnets of the magnetic coupler, the cost of the electrical drive system is relatively high, including the purchase cost of equipment such as motors, controllers, sensors, and the cost of installation, commissioning, and maintenance. This will increase the overall cost of the magnetic coupler torque test device. Therefore, we need to simplify the structure of the existing magnetic coupler to reduce costs and make the test process of the magnetic coupler simpler and more efficient. Summary of the invention

[0049] In order to supplement the specific structure of the locking mechanism 27, the following features are also specifically provided:

[0050] The locking mechanism 27 includes an adapter frame 28, a driving gear 30, a driven gear 31, a positioning frame 29, a driving bevel gear 32 and a driven bevel gear 33. The driving gear 30 is fixedly arranged on the upper end of the flip plate 23 through a gear seat. The adapter frame 28 is fixedly connected to the upper end of the flip plate 23. One end of the adapter frame 28 is coaxially connected to the lower end of the driving gear 30, and the other end is connected to the driven gear 31 (refer to Figure 5 ), the driven gear 31 is meshed with the driving gear 30, the positioning frame 29 is fixedly connected to the upper end of the flip plate 23, the driving bevel gear 32 is rotatably connected to the positioning frame 29 through the bevel gear frame and is coaxially fixedly connected to the driven gear 31, and the driven bevel gear 33 is rotatably connected to the bevel gear frame and meshes with the driving bevel gear 32.

[0051] In order to further supplement the specific structure of the locking mechanism 27, the following features are also specifically provided:

[0052] The locking mechanism 27 also includes a residual tooth 34, a push plate 36, a push rack 35, a self-locking device 37, a central disk 46, a central rack 47, a central gear 48 and two push racks 35. The residual tooth 34 is rotatably connected to the positioning frame 29 and is coaxially fixedly connected to the driven bevel gear 33 (refer to Figure 5 and Figure 7 ), the push plate 36 is slidably connected to the side of the positioning frame 29 away from the driven gear 31, the two push racks 35 are symmetrically arranged on both sides of the residual teeth 34 and are fixed to the push plate 36, the residual teeth 34 are alternately meshed with the two push racks 35, the center disk 46 is rotatably connected to the middle of the flip plate 23, and the center gear 48 is coaxially rotatably connected to the center disk 46 (reference Figure 8 ), the center rack 47 is slidably connected to the center disk 46 and meshes with the center gear 48, and the self-locking device 37 is fixedly connected to the center disk 46 (refer to Figure 7 ), when the push plate 36 moves toward the direction close to the center disk 46, it will abut against the input end of the self-locking device 37, the output end of the self-locking device 37 is fixedly connected to the center rack 47, the center disk 46 close to the positioning box 6 is disassembled and connected to the input end of the torque meter 5 through a clutch, and the center disk 46 close to the lifting frame 12 is disassembled and connected to the main gear 11 through a clutch. When the residual tooth 34 rotates, the residual tooth 34 will mesh with the two push racks 35 in turn. At this time, the two push racks 35 will drive the push pressure plate 36 fixed thereto to move in turn. After the push pressure plate 36 moves downward, it will drive the center rack 47 to move through the self-locking device 37. When the center rack 47 moves, it will drive the center gear 48 meshing with it to rotate. Then, when the self-locking device 37 is locked, during the rotation of the center disk 46, the center rack 47 will not reset itself (the self-locking device 37 here is a mature existing technology, specifically named a push-type spring buckle. In order to push the center rack 47 to reset, the spring in the self-locking device 37 selected in this device is a high-strength spring).

[0053] In order to clamp and position the inner magnetic body 7 or the outer magnetic body 13, the following features are also specifically provided:

[0054] The locking mechanism 27 further includes a clamping disc 49, a positioning disc 53, a plurality of clamping pins 51 and a plurality of clamping claws 52. The clamping disc 49 is coaxially fixedly connected to the central gear 48 and is rotatably connected to the central disc 46 (refer to Fig. 9 ), the clamping disc 49 is formed with a plurality of clamping arc grooves 50 at equal angles along the circumferential direction (refer to Fig.10 ), one end of a plurality of snap-in pins 51 is slidably connected to a plurality of snap-in arc grooves 50, and the other end is fixedly connected to a plurality of snap-in claws 52, and a positioning disc 53 is coaxially fixedly connected to a central disc 46 (reference Fig. 9), a plurality of engaging claws 52 are respectively connected with the positioning disc 53 in a sliding manner. When the central gear 48 rotates, the central gear 48 drives a plurality of engaging pins 51 to move along the engaging arc groove 50 through the engaging disc 49. When the engaging pins 51 move, they drive the engaging claws 52 fixed thereto to move. After the engaging claws 52 move, they clamp the inner magnetic body 7 or the outer magnetic body 13. Then, when the central disc 46 rotates, the central disc 46 drives the positioning disc 53 to rotate. The positioning disc 53 drives the inner magnetic body 7 or the outer magnetic body 13 to rotate through a plurality of engaging claws 52 (it should be noted that the rotation of the central disc 46 near the lifting frame 12 is an active rotation driven by the main gear 11, and its purpose is to drive the outer magnetic body 13 to rotate, while the rotation of the central disc 46 near the positioning box 6 is a passive rotation caused by magnetic force, and its purpose is to cause the value of the torque meter 5 to change when the inner magnetic body 7 rotates).

[0055] In order to supplement the specific structure of the positioning disc 53, the following features are also specifically provided:

[0056] The locking mechanism 27 further includes a plurality of elastic clamping mechanisms 55, which are arranged in an array with equal intervals along the circumference of the positioning disk 53 (refer to Fig. 9 ), the positioning disc 53 is formed with a plurality of limit slots 54 in an array with equal angles along the circumferential direction (refer to Fig.10 ), a plurality of clamping claws 52 are slidably connected with a plurality of limit slots 54. When the clamping claws 52 move, the clamping claws 52 will be slidably connected with the limit slots 54, thereby preventing the clamping claws 52 from being unable to clamp on the outer edge of the inner magnetic body 7 or the outer magnetic body 13.

[0057] In order to supplement the specific structure of the elastic clamping mechanism 55, the following features are also specifically provided:

[0058] The elastic clamping mechanism 55 further includes a positioning support 56, a movable support 57, a plurality of positioning pins 58, a plurality of abutting springs 59 and a plurality of abutting balls 60 (see Fig.10), the positioning support 56 is fixedly connected to the positioning disc 53, the movable support 57 is arranged on one side of the positioning support 56 close to the center of the positioning disc 53, one end of a plurality of positioning pins 58 is fixedly connected to the movable support 57, and the other end is slidably connected to the positioning support 56, a plurality of tightening springs 59 are respectively sleeved on the outside of the plurality of positioning pins 58, one end of the tightening springs 59 is fixedly connected to the positioning support 56, and the other end is fixedly connected to the movable support 57, and a plurality of tightening balls 60 are respectively rotatably connected to the side of the movable support 57 away from the positioning support 56. When the two discharge mechanisms 2 place the inner magnetic body 7 and the outer magnetic body 13 on the corresponding positioning disc 53, the plurality of tightening balls 60 will be pressed against the outer walls of the inner magnetic body 7 and the outer magnetic body 13 under the action of the plurality of tightening springs 59, so as to realize the preliminary positioning of the inner magnetic body 7 and the outer magnetic body 13, so that the subsequent plurality of clamping claws 52 can further clamp and limit the inner magnetic body 7 and the outer magnetic body 13.

[0059] The working principle of the device is that when the device is running, one unloading mechanism 2 can install the inner magnetic body 7 on the fixture 18 at the positioning box 6, and the other unloading mechanism 2 can install the outer magnetic body 13 on the fixture 18 of the lifting frame 12 (refer to Figure 1 and Figure 2 ), then the operator starts the sliding mechanism 4 and drives the positioning box 6 to move in the direction close to the jacking frame 12 until the inner magnetic body 7 is inserted into the outer magnetic body 13. At this time, the operator starts the jack 9. After the output end of the jack 9 moves upward, it will push the round rack 10 to move. After the round rack 10 moves, it will drive the main gear 11 meshing with it to rotate. After the main gear 11 rotates, it will drive the inner magnetic body 7 to rotate through the clamp 18. After the inner magnetic body 7 rotates, it will drive the output end of the torque meter 5 to rotate through the clamp 18. While the inner magnetic body 7 remains stationary, the outer magnetic body 13 rotates and the magnet shifts, and the torque meter 5 displays the currently measured torque in real time. When the maximum torque of the magnetic coupling is exceeded, the outer magnetic body 13 will quickly displace to the next magnetic pole, and the torque meter 5 displays the currently measured peak torque.

[0060] When loading and unloading the inner magnetic body 7 and the outer magnetic body 13 before and after the detection, as the sliding mechanism 4 drives the positioning box 6 to move, during loading, the two flip plates 23 will face the two unloading mechanisms 2, so that the two unloading mechanisms 2 can move the inner magnetic body 7 and the outer magnetic body 13 to the flip plates 23 respectively. When the two unloading mechanisms 2 place the inner magnetic body 7 and the outer magnetic body 13 on the corresponding positioning disks 53, a number of clamping balls 60 will be pressed against the outer walls of the inner magnetic body 7 and the outer magnetic body 13 under the action of a number of clamping springs 59, so as to achieve preliminary positioning of the inner magnetic body 7 and the outer magnetic body 13.

[0061] When the inner magnetic body 7 and the outer magnetic body 13 have completed the initial positioning, as the sliding mechanism 4 is started, the two flip plates 23 will be folded 90° until the inner magnetic body 7 and the outer magnetic body 13 are coaxially arranged relative to each other. During this process, the center disk 46 near the positioning box 6 is connected to the input end of the torque meter 5 through a clutch, and the center disk 46 near the lifting frame 12 is connected to the main gear 11 through a clutch (the clutch here is a mature existing technology, which is used to connect two shafts that are close to each other and gradually pressed together, specifically a tooth clutch that can be elastically engaged and separated). During the folding process of the flip plate 23, a number of clamping claws 52 can clamp and limit the inner magnetic body 7 and the outer magnetic body 13, and the self-locking device 37 can ensure that the inner magnetic body 7 and the outer magnetic body 13 will not reset themselves during the detection process, thereby enhancing the stability of the device.

[0062] After the detection is completed, the sliding mechanism 4 drives the positioning box 6 to move away from the lifting frame 12. At this time, the two flip plates 23 will return to the state of facing the two unloading mechanisms 2, so that the two unloading mechanisms 2 can unload the inner magnetic body 7 and the outer magnetic body 13 on the same side to improve the detection efficiency.

[0063] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
