Abstract
The invention discloses a high-stability high-precision adjusting device comprising a supporting frame and an adjusting structure arranged on the supporting frame. The adjusting structure comprises a rotating shaft and a rotating disc which is in sleeved on the rotating shaft; the circumference of the rotating disc is provided with a plurality of cross rods; the rotating shaft penetrates through the supporting frame and is matched with the supporting frame through a screw thread; a connecting head is fixed at the lower end of the rotating shaft; and the connecting head is movably connected with a wire-connecting rod. Through adopting the above structure, in a process of automobile engine vibration test and analysis, the high-precision adjusting device makes the adjustment of a gravity sensor more stable; deviation is avoided; and meanwhile, a precise adjustment position can be obtained easier.
Description
Technical field
The present invention relates to automobile detection, analysis field, the high precision regulating device that specifically a kind of stability is higher.
Background technology
Vehicle testing technique is from auto repair derives from technology out, is accompanied by the development of automotive engineering by auto repair.It is the inspection for determining that technical condition of vehicle or ability to work are carried out that automobile detects, automobile in use, prolongation along with service time, its part weares and teares gradually, burn into distortion, aging and deterioration of lubricant etc., cause matching pair gap to become large, cause motion looseness, vibrate, make sound, leak gas, leak, leakage of oil etc., cause automotive engineering hydraulic performance decline.
Along with social development, the comfortableness that automobile is driven becomes the problem that people pay close attention to gradually, and the vibration of engine is an important aspect.When engine produces judder, not only make body vibration itself, also make the parts of engine interior and auxiliary equipment, vehicle frame etc. produce and vibrate, thereby affect serviceability, life-span and the environment around of vehicle.Therefore, to regularly to automobile, carry out engine luggine test analysis, and gravity sensor can be used in the essential ground of the analysis of vibration measurement of engine, during test analysis, gravity sensor must be in tension, owing to can use a plurality of gravity sensors when testing, not only troublesome poeration, efficiency are low will to strain respectively each gravity sensor, but also may cause negligence of operation, affect Measurement results.Also have, in the time of adjusting, because regulating device is unstable, easily cause regulating producing deviation, and be difficult for reaching comparatively accurate position.
Summary of the invention
The invention provides the high precision regulating device that a kind of stability is higher, solved in the past in motor car engine analysis of vibration measurement process, the adjusting of gravity sensor is unstable, easily causes regulating producing deviation, and is difficult for reaching comparatively accurate position problems.
The present invention is that technical solution problem is achieved through the following technical solutions: the high precision regulating device that a kind of stability is higher, comprise bracing frame and be arranged on the adjustment structure on bracing frame, described adjustment structure comprises rotating shaft and is socketed in the rotating disc in rotating shaft, the circumference of rotating disc is provided with some cross bars, described rotating shaft is through bracing frame, and between rotating shaft and bracing frame,, by threaded engagement, the lower end of rotating shaft is fixed with connector, is connected with wiring rod on connector.
Support frame as described above comprises two root posts of crossbeam and supporting traverse, and the bottom of column is bolted on work top, and rotating shaft is longitudinally through crossbeam.
In rotating shaft between described rotating disc and bracing frame, be socketed with support annulus, and support annulus is fixed on bracing frame.
Described rotating disc is provided with three cross bars, and three cross bars are positioned in same level, and the angle between adjacent crossbars is 120 degree.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) between bracing frame of the present invention and rotating shaft, pass through threaded engagement, effectively reduced like this rocking that rotating shaft may occur, make whole adjustment operation more stable.
(2) the present invention adopts cross bar to rotate rotating disc, owing to there being many cross bars, therefore, in rotation process, can find a suitable cross bar of angle to rotate rotating disc, thereby facilitate adjusting, more easily obtains higher degree of regulation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The name that Reference numeral is corresponding is called: 1, bracing frame, 2, support annulus, 3, rotating shaft, 4, rotating disc, 5, cross bar, 6, connector, 7, wiring rod.
