Abstract

The invention discloses a rotating shaft locking device. A rotating shaft of a calibrated system is required to be locked to facilitate the loading of standard torque during on-spot torque parameter system calibration. A conventional method of designing special locking devices for calibrated systems with different structures and sizes is adopted, and is poor in universality, the field calibration cost is increased, and the operating progress is influenced. According to the rotating shaft locking device provided by the invention, the size range of rotating shafts which can be locked is wide, the rotating shaft locking device is slightly influenced by the structure and size of the calibrated system, and the problem of poor universality of a conventional locking mode is solved. In addition, the rotating shaft locking device has the technical improvements and technical characteristics as follows: 1, the rotating shaft locking device is small in size, light in weight and convenient to carry; 2, a dual locking mode is adopted, so that the rotating shaft locking device is high in locking force moment and locking reliability; 3, the rotating shaft can be rapidly locked without changing the structure of the calibrated system during locking, so that the locking efficiency is greatly improved, and the labor intensity is reduced.

Description

A kind of rotating shaft locking device
Affiliated technical field:
This patent of invention belongs to a kind of rotatory mechanical system rotating shaft locking device, is specially adapted to torque parameter fielded system when calibration to by the locking of calibration system rotating shaft.
Goal of the invention:
Provide 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 the problem that the tight mode cost of traditional locks is high, efficiency is low, versatility is poor.
Background technique:
While carrying out the calibration of torque parameter fielded system, must be by the rotating shaft locking by calibration system so that the loading of standard torque.Conventional method is: for each different structure, size by calibration system, designed special locking device, this method lacks versatility, has increased the cost of field calibration work, affects job schedule.
Rotating shaft locking device of the present invention is by adopting the mode of locking up and down rotating disk and Locking bushing combination, the dimensional range that guaranteed to lock rotating shaft is wide, it is little to be subject to by calibration system structure and size impact, overcome the poor problem of traditional locking mode versatility, and increased 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; While 3. locking, without changing, by calibration system structure, can be realized rotating shaft quick locking, greatly improve locking efficiency, reduce labor intensity.
Technological scheme:
A rotating shaft locking device, comprises locking rotating disk (1), and 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 curve with channel-section steel, regulate village's cover (3) to adopt cylinder to form from middle symmetrical incision, be positioned between locking rotating disk (1) and lower locking rotating disk (2), between upper locking rotating disk (1) and lower locking rotating disk (2), adopt screw to connect, by screw, on upper locking rotating disk (1) and lower locking rotating disk (2), apply positive pressure, thereby increase the frictional force regulating between village's cover (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) with by the coupling on calibration system (8), be fixed, further strengthen 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, during locking, without changing, by calibration system structure, can be realized rotating shaft quick locking, greatly improve locking efficiency, reduce labor intensity.
Accompanying drawing explanation:
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 rotating shaft locking device, comprises locking rotating disk 1, and 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 curve with channel-section steel, regulate village's cover 3 to adopt cylinder to form from middle symmetrical incision, between upper locking rotating disk 1 and lower locking rotating disk 2, between upper locking rotating disk 1 and lower locking rotating disk 2, adopt screw to connect, by screw, on upper locking rotating disk 1 and lower locking rotating disk 2, apply positive pressure, thereby increase the frictional force regulating between village's cover 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 with by the coupling on calibration system, be fixed, further strengthen lock ability and reliability.
By upper and lower locking rotating disk and adjusting lining, hold rotating shaft tightly, on locking lever, apply reaction force, prevent that rotating shaft rotation from reaching locking object.
Device mainly contains two kinds of rotating shafts and holds mode tightly, mode one: measure the diameter that will lock rotating shaft, according to rotating shaft diameter, select the adjusting lining of corresponding size, then by shown in Fig. 1, with screw, three is fixed, screw tentatively tightens up the adjusting play that has 1~2mm left and right between the upper and lower locking rotating disk of rear assurance.During work, by increasing the screwing force of screw, strengthen the positive pressure regulating between lining and rotating shaft, thereby strengthen frictional force between the two, reach and hold object tightly.Mode two: for rotatory mechanical system, for the ease of installing all, can increase coupling in the front and back of some key components and partss, on a lot of coupling, be evenly distributed with the round hole slot that a circle is equipped with pin, mode two is exactly to utilize these round hole slots, round hole slot on waist-shaped hole groove on upper and lower locking rotating disk and coupling, by screw fastening, is reached and holds object tightly.
