Description

Technical Field

[0001] The utility model relates to the technical field of torque sensors, in particular to a magnetically fixed torque sensor connection device. Background Art

[0002] Torque sensors, also known as force sensors, torque sensors, torque transducers, and torque meters, are categorized into two main types: dynamic and static. Dynamic torque sensors can also be called torque sensors, torque-speed sensors, non-contact torque sensors, and rotary torque sensors. Torque sensors detect the torsional moment acting on various rotating or non-rotating mechanical components. They convert the physical change in torque into a precise electrical signal. Torque sensors are used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches. They offer advantages such as high accuracy, fast frequency response, excellent reliability, and long life.

[0003] In the existing technology, the torque sensor and the device under test are usually connected using a magnetic coupling, which generally uses permanent magnets for connection. Due to the strong magnetic force of the permanent magnets, it is relatively difficult to disassemble the magnetic coupling. Therefore, we have introduced a magnetically fixed torque sensor connection device. Utility Model Content

[0004] The purpose of the present utility model is to provide a magnetically fixed torque sensor connection device, which can not only quickly connect the first coupling and the second coupling, but also quickly disassemble the first coupling and the second coupling, thereby improving the disassembly and assembly efficiency and reducing the labor intensity of the staff, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A magnetically fixed torque sensor connection device includes a torque sensor body, both ends of the torque sensor body are rotatably provided with a rotating shaft, the two ends of the rotating shafts are provided with a connecting mechanism, the connecting mechanism includes a first coupling and a second coupling, the first coupling and the second coupling are provided with a slot that cooperates with the rotating shaft on the opposite sides, four sector-shaped blocks are fixedly provided at the edges of the opposite sides of the first coupling and the second coupling, a permanent magnet is fixedly provided at the middle of the four sector-shaped blocks of the second coupling, a strip hole is provided on the side wall of the first coupling, and a quick release mechanism is provided in the strip hole.

[0007] Furthermore, the quick-release mechanism includes a movable connecting part, which is fixedly arranged in the middle of the hole wall on one side of the strip hole close to the permanent magnet. The movable connecting part is rotatably provided with two rotating rods, one end of the rotating rod extends to the outside of the strip groove, and a push rod is fixedly provided on the rod wall on one side of the rotating rod close to the permanent magnet. The hole wall of the strip hole is provided with a through hole that cooperates with the push rod.

[0008] Furthermore, a push ring is fixedly provided on the circumferential wall of the first coupling.

[0009] Furthermore, a push plate is fixedly provided on one end of the rotating rod located outside the strip-shaped hole.

[0010] Furthermore, one end of the push rod close to the permanent magnet is configured as an arc-shaped surface.

[0011] Furthermore, the permanent magnet is configured to be circular.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The magnetically fixed torque sensor connection device is provided with a torque sensor body, a rotating shaft, a pushing ring, a second coupling, a first coupling, a sector-shaped block, a permanent magnet, a push rod, a push plate, a rotating rod, and a movable connecting piece, so that the multiple sector-shaped blocks on the second coupling are clamped with the multiple sector-shaped blocks on the first coupling. At this time, the permanent magnet is attracted to the first coupling, and the rotating shaft can drive the torque device to be measured to rotate through the sector-shaped block between the first coupling and the second coupling. The permanent magnet can ensure that the multiple sector-shaped blocks are always clamped. When the first coupling and the second coupling need to be disassembled, the thumb is used to press against the pushing ring and the index finger to hook the pushing plate. The pushing plate drives the rotating rod to rotate, and the rotating rod drives one end of the push rod to pass through the through hole and push the second coupling open. Not only can the first coupling and the second coupling be quickly connected, but the first coupling and the second coupling can also be quickly disassembled, thereby improving the disassembly and assembly efficiency and reducing the labor intensity of the staff.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3 , the utility model provides a technical solution:

[0020] A magnetically fixed torque sensor connection device includes a torque sensor body 1, both ends of the torque sensor body 1 are rotatably provided with a rotating shaft 2, the two ends of the two rotating shafts 2 facing away from each other are provided with a connecting mechanism, the connecting mechanism includes a first coupling 5 and a second coupling 4, the first coupling 5 and the second coupling 4 are provided with a slot that cooperates with the rotating shaft 2 on the side facing away from each other, four sector-shaped blocks 6 are fixedly provided at the edge of the opposite side of the first coupling 5 and the second coupling 4, and a permanent magnet 7 is fixedly provided at the middle of the four sector-shaped blocks 6 of the second coupling 4. The permanent magnet 7 is set to be circular, and the circular shape can maximize the area of the permanent magnet 7 between the multiple sector-shaped blocks 6, thereby improving the magnetic attraction strength of the permanent magnet 7 and the first coupling 5. Since the first coupling 5 is a metal product, it can be magnetically attracted to the permanent magnet 7.

[0021] The side wall of the first coupling 5 is provided with a strip hole, and a quick-release mechanism is provided in the strip hole. The quick-release mechanism includes a movable connecting piece 11, which is fixedly arranged in the middle of the hole wall on one side of the strip hole near the permanent magnet 7. The movable connecting piece 11 is rotatably provided with two rotating rods 10, and one end of the rotating rod 10 extends to the outside of the strip groove, and a push rod 8 is fixed on the rod wall on one side of the rotating rod 10 near the permanent magnet 7. The hole wall of the strip hole is provided with a through hole that cooperates with the push rod 8. The circumferential wall of the first coupling 5 is fixed with a pushing ring 3. The push ring 3 and the two rotating rods 10 can further facilitate the disassembly of the first coupling 5 and the second coupling 4. The end of the rotating rod 10 outside the strip hole is fixed with a push plate 9. The push plate 9 is convenient for the staff to push the rotating rod 10. The end of the push rod 8 close to the permanent magnet 7 is set to an arc surface. The arc surface reduces the friction when the push rod 8 pushes the fan-shaped block on the second coupling.

[0022] When in use, the multiple sector-shaped blocks 6 on the second coupling 4 are engaged with the multiple sector-shaped blocks 6 on the first coupling 5. At this time, the permanent magnet 7 is attracted to the first coupling 5, and the rotating shaft 2 can drive the torque device to be measured to rotate through the sector-shaped blocks 6 between the first coupling 5 and the second coupling 4. The permanent magnet 7 can ensure that the multiple sector-shaped blocks 6 are always engaged. When the first coupling 5 and the second coupling 4 need to be disassembled, use the thumb to press against the push ring 3 and the index finger to hook the push plate 9. The push plate 9 drives the rotating rod 10 to rotate. The rotating rod 10 drives one end of the push rod 8 to pass through the through hole and push the second coupling 4 open. Not only can the first coupling 4 and the second coupling 4 be quickly connected, but the first coupling 5 and the second coupling 4 can also be quickly disassembled, which improves the disassembly and assembly efficiency and reduces the labor intensity of the staff.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
