The push-pull dynamometer of an operating level comprises a shell, a deformable rod, a grip sleeve, a shaft and a dial indicator, wherein the deformable rod is arranged inside the shell; the grip sleeve is arranged outside the shell; the deformable rod, the shell and the grip sleeve are connected by the shaft in such a manner that the shaft penetrates through the deformable rod, the shell and the grip sleeve; the deformable rod is an elastic body which is hollow and provided with a groove on the lower part; a 45 DEG inclined plane is formed between the top part of the deformable rod and the top part of the shell; the dial indicator is obliquely inserted into the top part of the shell and a 90 DEG angle is formed between the dial indicator and the inclined plane on the top part of the shell, and a measuring head of the dial indicator contacts and is perpendicular to the 45 DEG inclined plane of the deformable rod; the deformable rod is fixed in the shell by a compression nut; and the shaft and the dial indicator are fixed by a cylindrical head screw and a fastening screw respectively. The push-pull dynamometer provided by the utility model is solid and durable, simple in operation, sensitive and accurate in measurement indication, and easy to read, and improves the correcting efficiency of the operating level greatly.
Description
Technical field
The utility model belongs to the measuring appliance designing technique, relates to a kind of dynamometer that is used to measure operating rod thrust and pulling force.
Background technology
Thrust, pulling force size to operating rod in the helicopter control process have different requirement for restriction, need-5N in the adjustment process～5N ,-20N～20N ,-50N～50N ,-device for measuring force of four kinds of different ranges of 200N～200N.Current measuring methods is that the survey instrument with similar cartridge type spring balance hitches operating rod, and positive and negative both direction draws operating rod, read push away, the size of pulling force degree.This measuring method shortcoming is: survey instrument is connected not firm with operating rod, is prone to during great efforts come off; The distance that device for measuring force is pulled out during ± 200N is very long, and reading numerical values is inconvenient; When measuring thrust, the direction of drawing is towards control desk, and the space is limited to; One-piece construction is unstable, and is fragile.
The utility model content
The utility model technical matters to be solved is: provide that a kind of reflection promptly and accurately pushes away, the dynamometric device of pulling force size, be convenient to detect helicopter control bar and other device and go up the pushing away of joystick-like, pulling force degree size.
The technical scheme of the utility model is: a kind of push-and-pull dynamometer of operating rod; It comprises housing, deformed rod, hold cover, axle and dial gauge; Deformed rod is equipped with in the inside of housing, and the outside is equipped with and is held cover, deformed rod, housing and hold cover and pass across the three through axle and be connected; Deformed rod is the elastic body that hollow and bottom have groove; The deformed rod top becomes the 45 inclined-plane with case top; The dial gauge oblique cutting is gone into case top, and with the case top inclined-plane at an angle of 90, dial gauge measuring head contact and perpendicular to the 45 inclined-plane of deformed rod; Gland nut is fixed on deformed rod in the housing; Axle and dial gauge are fixed with fillister head screw and trip bolt respectively.
The beneficial effect of the utility model is: use the utility model, can detect promptly and accurately that operating rod pushes away, the dynamics of pull action size, durable, simple to operate, the dynamometry indication is sensitive, is easy to reading numerical values, does not receive limited space, significantly improves work efficiency.The on-the-spot proof of using, the dynamometry adjustment efficient of operating rod has improved more than 3 times.
Description of drawings
Fig. 1 is the front elevation of a kind of embodiment of the utility model;
Fig. 2 is the cut-open view of a kind of embodiment of the utility model shown in Figure 1 along A-A;
Wherein, 1-gland nut, 2-housing, 3-deformed rod, 4-hold cover, 5-fillister head screw, 6-axle, 7-dial gauge, 8-trip bolt.
Embodiment
Explain further details below in conjunction with the embodiment of accompanying drawing to the utility model.Referring to Fig. 1 and Fig. 2, a kind of push-and-pull dynamometer of operating rod, it comprises housing 2, deformed rod 3, holds cover 4, axle 6 and dial gauge 7; Deformed rod 3 is equipped with in the inside of housing 2, and the outside is equipped with and is held cover 4, deformed rod 3, housing 2 and hold cover 4 and pass across the three through axle 6 and be connected; Deformed rod 3 has the elastic body of groove for hollow and bottom; Deformed rod 3 tops become the 45 inclined-plane with housing 2 tops; Dial gauge 7 oblique cuttings are gone into housing 2 tops, and with inclined-plane, housing 2 top at an angle of 90, dial gauge 7 measuring heads contact and perpendicular to the 45 inclined-plane of deformed rod 3; Gland nut 1 is fixed on deformed rod 3 in the housing 2; Axle 6 is fixing with trip bolt 8 with fillister head screw 5 respectively with dial gauge 7.
Before the dynamometer combine and assemble, change the range of dial gauge 7 through the groove size of repair deformed rod 3.Deformed rod 3 is pushed away, deformation takes place during pulling force, and 45 ° of inclined-planes of deformed rod 3 drive with it that the measuring head of the dial gauge 7 of contact moves up and down, and pushes away, the sizes values of pulling force embodies in the rotation of dial gauge 7 pointers.Groove is dark more greatly more, and the groove entity is more little, and deformation takes place deformed rod 3 more easily, and the power that the moving scale of dial gauge 7 pointer revolutions needs is less, and whole dynamometry metering journey is little; Otherwise the dynamometer range is big.Thrust is for just, and dial gauge 7 pointers clockwise rotate; Pulling force is for negative, and dial gauge 7 pointers rotate counterclockwise.The corresponding relation of the size of power and dial gauge 7 index dials passes through calibration of weight.Above-mentioned, can realize dynamometer-5N～5N ,-20N～20N ,-50N～50N ,-the pushing away of four kinds of different ranges of 200N～200N, value of thrust measure, and can realize that also the pushing away of other range of joystick-like device, value of thrust measure.
The method of application of the utility model is: with gland nut 1 and the socket of operating rod termination, hold and hold cover 4, push away, draw operating rod with suitable dynamics, direct read through the pointer of dial gauge 7 push away, pulling force numerical value.
The fillister head screw 5 of the utility model, dial gauge 7, trip bolt 8 adopt finished parts.
