The weighing means 3 are arranged to weigh the material,
the weighing means 3 is arranged to detect the torque transmitted through the drive shaft 12. The weighing mechanism 3 is structurally characterized in that the weighing mechanism 3 comprises a weighing clamping block 31 fixed at the end part of a transmission shaft 12, the longitudinal section of the weighing clamping block 31 is C-shaped, the transmission shaft 12 is fixed at the back of an opening of the weighing clamping block 31, and a flat key is arranged between the transmission shaft 12 and the weighing clamping block 31 to ensure that the weighing clamping block 31 can rotate along with the transmission shaft 12, so that the torque of the dimming motor body 2 is transmitted to the weighing clamping block 31 through the transmission shaft 12; a weighing sensor 32 is clamped in an opening of the weighing clamping block 31, and the weighing sensor 32 is also fixed with the weighing clamping block 31 through a bolt; be provided with a weighing base 33 at weighing sensor 32's weighing end bottom wall, this weighing base 33 and chassis 5 fixed connection, the top of this weighing base 33 is in on the same horizontal plane with the tight holding surface of clamp splice 31's clamp, then weighing sensor 32 keeps the horizontality, weighing sensor 32's weighing end offsets with weighing base 33, when weighing clamp splice 31 drives weighing sensor 32's weighing end extrusion weighing base 33, weighing sensor 32 receives the stress change, then weighing sensor 32's reading changes, and then obtain weighing clamp splice 31's moment of torsion, the moment of torsion of dimming motor body 2 promptly.
The clamping mechanism (4) is arranged on the upper portion of the frame,
the clamping mechanism 4 is fixed at the other end of the transmission shaft 12, the clamping mechanism 4 is used for clamping a motor shaft of the dimming motor body 2, specifically, the clamping mechanism 4 comprises a plurality of clamping heads 41, and the clamping heads 41 can be mutually closed and clamp the motor shaft of the dimming motor body 2.
After each clamp head 41 presss from both sides tight motor shaft of dimming motor body 2, make the motor shaft have the rotation trend through the work of dimming motor body 2, and then make transmission shaft 12 have the rotation trend through clamping mechanism 4, and then make clamp splice 31 of weighing have the rotation trend, and then drive weighing sensor 32's the end extrusion of weighing base 33, reachs the moment of torsion of transmission shaft 12 through weighing sensor 32 promptly, and then reachs the moment of torsion of dimming motor body 2. However, since the dimming motor body 2 is coated with a layer of lubricating oil during use or leaving the factory, when the lubricating oil exists on the motor shaft of the dimming motor body 2, the clamping effect between the clamping head 41 and the motor shaft of the dimming motor body 2 is not good enough, and the phenomenon that the clamping head 41 and the motor shaft of the dimming motor body 2 slip may occur, thereby affecting the accuracy of measuring the torque of the dimming motor body 2.
In order to solve the above problem, it is necessary to design a scheme that an oil inlet 411 is formed at an end of the clamping head 41, specifically, the oil inlet 411 is located at an end of the clamping head 41 away from the transmission shaft 12, and the oil inlet 411 is used for temporarily storing lubricating oil; the two side walls of the clamping head 41 are obliquely arranged and respectively form a scraper 412, the scraper 412 can abut against the motor shaft of the dimming motor body 2 and scrape lubricating oil when the two side walls rotate relatively, specifically, the width of the clamping head 41 is gradually reduced from one side of the transmission shaft 12 to the side of the dimming motor body 2 inserted into the motor shaft, that is, the scraper 412 can guide the lubricating oil, and the lubricating oil can flow to the position of the oil inlet 411 along the scraper 412; an oil outlet 413 communicated with the oil inlet 411 is formed in the inner wall of the clamping head 41, and the surface friction coefficient of the inner wall of the clamping head 41 is increased through the arrangement of the oil outlet 413, so that the clamping effect of the clamping head 41 on the motor shaft of the dimming motor body 2 is improved, and the detection accuracy of the dimming motor body 2 is further ensured; when the clamping head 41 clamps the motor shaft of the dimming motor body 2, the clamping head 41 is firstly contacted with the motor shaft of the dimming motor body 2, and at this time, the clamping head 41 does not clamp the motor shaft of the dimming motor body 2, the scraper 412 pushes the lubricating oil on the surface of the motor shaft of the dimming motor body 2 to be linear extending along the axial direction of the motor shaft by the operation of the dimming motor body 2, the motor shaft of the dimming motor body 2 is pulled out and rotated to the oil guide port 415 corresponding to the linear lubricating oil, the motor shaft of the dimming motor body 2 is inserted again, so that the linear lubricating oil enters the oil inlet 411 and is collected in the oil inlet 411, the amount of lubricating oil on the surface of the motor shaft of the dimming motor body 2 is reduced, so that the situation that the clamping head 41 and the motor shaft of the dimming motor body 2 slip is avoided, and the accuracy of measurement of the dimming motor body 2 is guaranteed; after the detection is finished, the clamping head 41 loosens the motor shaft of the dimming motor body 2, lubricating oil in the oil inlet 411 can be released through the oil outlet 413, and the situation of rusting and corrosion of the clamping head 41 is avoided through the maintenance effect of the lubricating oil on the clamping head 41.
It should be noted that, during a long time use, the lubricating oil in the oil inlet 411 may flow back from the oil inlet 411, and when the clamping head 41 clamps the motor shaft of the dimming motor body 2, a part of the lubricating oil may run off, so that the lubricating oil released to the clamping head 41 when the clamping head 41 is idle is less, the protection effect on the clamping head 41 is poor, in order to solve the above problem, a scheme is required to be designed, in which a collecting groove 414 is disposed inside the clamping head 41, the collecting groove 414 extends along the axial direction of the clamping head 41, and two ends of the collecting groove 414 are respectively communicated with the oil inlet 411 and the oil outlet 413; the width of the collecting tank 414 is greater than that of the oil inlet 411, and the highest point of the collecting tank 414 is equal to the highest point of the oil inlet 411 in height, that is, the collecting tank 414 is recessed downward to form an oil storage tank; after lubricating oil entered from the oil inlet 411, the lubricating oil can drop and collect in the collecting groove 414, because the collecting groove 414 and the oil inlet 411 are arranged in a ladder manner, the highest point of the oil inlet 411 is higher than the lowest point of the collecting groove 414, so the lubricating oil in the collecting groove 414 can only be discharged from the oil outlet 413 and is difficult to flow back from the oil inlet 411, therefore, the lubricating oil entered from the oil inlet 411 can be used for maintaining the clamping head 41, and the service life of the clamping head 41 is further prolonged.
In order to facilitate the collection of the lubricating oil in the collecting groove 414, the oil inlet 411 is disposed obliquely, and a lower position of the oil inlet 411 is provided with an oil guide port 415, and the oil guide port 415 is aligned with the linear lubricating oil on the surface of the motor shaft of the dimming motor body 2, so that the lubricating oil on the surface of the motor shaft of the dimming motor body 2 slides into the collecting groove 414; the width of the oil guide port 415 is gradually reduced from the oil inlet 411 to the oil outlet 413, so that the range area of the oil guide port 415 capable of sucking lubricating oil is enlarged, the situation that the lubricating oil is too much and cannot enter the oil guide port 415 is avoided, the lubricating oil can enter the oil guide port 415, the amount of the released lubricating oil is increased, and the protection effect on the clamping head 41 is improved; lubricating oil enters the oil inlet 411 from the oil guide port 415 and then falls into the collecting tank 414.
In order to further improve the service life of the clamping head 41, the groove bottom of the collecting groove 414 is obliquely arranged, lubricating oil flows to the oil outlet 413 along the groove bottom of the collecting groove 414, namely, one side, located at the oil outlet 413, of the groove bottom of the collecting groove 414 is low, the lubricating oil flows in a guiding manner through the design, then the lubricating oil in the collecting groove 414 can be released from the oil outlet 413, the residue of the lubricating oil in the collecting groove 414 is reduced, and the protection effect on the clamping head 41 is ensured.
In order to avoid detecting lubricating oil in the motor shaft process of the dimming motor body 2 to release from the oil outlet 413, thereby affecting the detection accuracy, the oil outlet 413 needs to be blocked in the detection process, in order to solve the above problems, the following scheme needs to be adopted, a baffle 42 capable of being rotatably connected is arranged in the collecting tank 414, the baffle 42 is similar to a valve core of a ball valve, when the baffle 42 rotates to be completely overlapped with the connection part of the oil outlet 413 and the collecting tank 414, the baffle 42 can block the oil outlet 413, and at this time, the lubricating oil in the collecting tank 414 cannot be released from the oil outlet 413.
Specifically, the baffle 42 is driven to rotate in a manner that a sliding groove 416 is formed at a connection position of the oil outlet 413 and the collecting groove 414, a sliding rod 43 is slidably connected in the sliding groove 416, a guide surface 431 is formed by obliquely arranging the bottom of the sliding rod 43, the baffle 42 is fixed at the top of the sliding rod 43, when the motor shaft of the dimming motor body 2 is inserted between the clamping heads 41, the motor shaft of the dimming motor body 2 is firstly contacted with the guide surface 431, during the continuous insertion process of the motor shaft of the dimming motor body 2, the sliding rod 43 rotates to a state that the baffle 42 can block the oil outlet 413, the motor shaft of the dimming motor body 2 is continuously inserted to push the sliding rod 43 to slide upwards along the sliding groove 416 and extend into the collecting groove 414 to block the oil outlet 413, and the guide surface 431 is matched with the motor shaft of the dimming motor body 2, so that the sliding rod 43 can drive the baffle plate 42 to lift and can drive the baffle plate 42 to rotate.
