Abstract
Carry out torque parameter fielded system calibration time, must by by the rotating shaft locking of calibration system so that the loading of standard torque.Conventional method is: for each different structure, size designed special locking device by calibration system, this method lacks versatility, adds the cost of field calibration work, affects job schedule.Rotating shaft locking device of the present invention can lock the dimensional range of rotating shaft wide, by by calibration system structure and size impact little, overcome the problem of traditional locking mode poor universality.There is following technological progress point and technical characteristics simultaneously: 1. volume is little, lightweight is easy to carry; 2. adopt double locking mode, locking torque is large, and reliable lock is high; 3. can be realized rotating shaft quick locking without the need to changing by calibration system structure during locking, substantially increasing locking efficiency, reducing labor intensity.
Description
Art:
This patent of invention belongs to a kind of rotatory mechanical system rotating shaft locking device, to by the locking of calibration system rotating shaft when being specially adapted to the calibration of torque parameter fielded system.
Goal of the invention:
There is provided a kind of lightweight, volume is little, locking is quick, locking torque is large and the rotating shaft locking device of highly versatile, effectively solves that traditional locks tight mode cost is high, efficiency is low, the problem of poor universality.
Background technique:
Carry out torque parameter fielded system calibration time, must by by the rotating shaft locking of calibration system so that the loading of standard torque.Conventional method is: for each different structure, size designed special locking device by calibration system, this method lacks versatility, adds the cost of field calibration work, affects job schedule.
Rotating shaft locking device of the present invention locks the mode of rotating disk and Locking bushing combination up and down by adopting, ensure that the dimensional range can locking rotating shaft wide, by by calibration system structure and size impact little, overcome the problem of traditional locking mode poor universality, and add with by the further locking mode of calibration system upper coupling.There is following technological progress point and technical characteristics: 1. volume is little, lightweight is easy to carry; 2. adopt double locking mode, locking torque is large, and reliable lock is high; 3. can be realized rotating shaft quick locking without the need to changing by calibration system structure during locking, substantially increasing locking efficiency, reducing labor intensity.
Technological scheme:
A kind of rotating shaft locking device, comprises locking rotating disk (1), lower locking rotating disk (2), regulates lining (3), locking lever (4) composition.The scoop that upper locking rotating disk (1) and lower locking rotating disk (2) likeness in form channel-section steel curve, regulate lining (3) to adopt cylinder to cut from intermediate symmetry to form, be positioned between locking rotating disk (1) and lower locking rotating disk (2), screw is adopted to connect between upper locking rotating disk (1) and lower locking rotating disk (2), on upper locking rotating disk (1) and lower locking rotating disk (2), positive pressure is applied by screw, thus increase the frictional force regulated between lining (3) and rotating shaft (5), realize preliminary locking, locking lever (4) and upper locking rotating disk (1), lower locking rotating disk (2) is fixedly connected with, it is characterized in that, on upper locking rotating disk (1) and lower locking rotating disk (2), have some waist-shaped holes (6), by connected element (7) by waist-shaped hole (6) be fixed by the coupling (8) on calibration system, further enhancing lock ability and reliability.
Beneficial effect:
Rotating shaft locking device of the present invention is applied widely, highly versatile, volume is little, lightweight is simultaneously easy to carry, adopt double locking mode, locking torque is large, reliable lock is high, rotating shaft quick locking can be realized without the need to changing by calibration system structure during locking, substantially increasing locking efficiency, reducing labor intensity.
Accompanying drawing illustrates:
Fig. 1 is the plan view of this rotating shaft locking device
Wherein, 1 is upper locking rotating disk, and 2 is lower locking rotating disk, and 3 for regulating lining, and 4 is locking lever, and 5 is rotating shaft, and 6 is waist-shaped hole, and 7 is connected element
Fig. 2 is the plan view of Fig. 1
Wherein, 8 is by the coupling on calibration system
Specific embodiments:
A kind of rotating shaft locking device, comprises locking rotating disk 1, lower locking rotating disk 2, regulates lining 3, and locking lever 4 forms.The scoop that upper locking rotating disk 1 and lower locking rotating disk 2 likeness in form channel-section steel curve, regulate lining 3 to adopt cylinder to cut from intermediate symmetry to form, between upper locking rotating disk 1 and lower locking rotating disk 2, screw is adopted to connect between upper locking rotating disk 1 and lower locking rotating disk 2, on upper locking rotating disk 1 and lower locking rotating disk 2, positive pressure is applied by screw, thus increase the frictional force regulated between lining 3 and rotating shaft, realize preliminary locking, locking lever 4 and upper locking rotating disk 1, lower locking rotating disk 2 is fixedly connected with, it is characterized in that, on upper locking rotating disk 1 and lower locking rotating disk 2, have some waist-shaped holes, by connected element by waist-shaped hole be fixed by the coupling on calibration system, further enhancing lock ability and reliability.
Hold rotating shaft tightly by upper and lower locking rotating disk and adjustment lining, locking lever applies reaction force, prevents axis of rotation from reaching locking object.
Device mainly contains two kinds of rotating shafts and holds mode tightly, mode one: measure the diameter will locking rotating shaft, the adjustment lining of corresponding size is selected according to rotating shaft diameter, then three fixed with screw by shown in Fig. 1, screw tentatively tightens up the adjusting play having about 1 ~ 2mm between the upper and lower locking rotating disk of rear guarantee.During work, by increasing the screwing force of screw, strengthen the positive pressure regulated between lining and rotating shaft, thus strengthen frictional force between the two, reach and hold object tightly.Mode two: for rotatory mechanical system, all coupling can be increased in the front and back of some key components and partss for the ease of installing, a lot of coupling is evenly distributed with the round hole slot that a circle is equipped with pin, mode two is exactly utilize these round hole slots, waist-shaped hole groove on upper and lower locking rotating disk and the round hole slot on coupling are passed through screw fastening, reaches and hold object tightly.
