Abstract
The utility model discloses a high-stability high-precision adjusting device. The high-precision adjusting device comprises 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 the rotating shaft; the circumference of the rotating disc is provided with a plurality of transverse rods; the rotating shaft penetrates 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 of the utility model makes the adjustment of a gravity sensor more stable and avoids deviation, and enables great easiness in obtaining a precise adjustment position at the same time.
Description
Technical field
The utility model 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 the auto repair derives from technology out, is accompanied by the development of automotive engineering by auto repair.The automobile detection is the inspection for determining that technical condition of vehicle or ability to work are carried out, automobile in use, prolongation along with service time, its part weares and teares gradually, burn into distortion, aging and deterioration of lubricant etc., cause the matching pair gap to become large, cause the motion looseness, vibrate, make sound, leak gas, leak, leakage of oil etc., cause the automotive engineering hydraulic performance decline.
Along with the development of society, the comfortableness that automobile is driven becomes people's problems of concern gradually, and the vibration of engine then is an important aspect.When engine produces judder, not only make body vibration itself, the parts of engine interior and auxiliary equipment, vehicle frame etc. are produced vibrate, thereby affect serviceability, life-span and the environment on every side of vehicle.Therefore, to regularly carry out the engine luggine test analysis to automobile, and the analysis of vibration measurement of engine essentially can be used gravity sensor, gravity sensor must be in tension during test analysis, owing to when test, can use a plurality of gravity sensors, not only troublesome poeration, efficient are low will to strain respectively each gravity sensor, but also may cause negligence of operation, affect Measurement results.Also have, because regulating device is unstable, easily cause regulating producing deviation in the time of adjusting, and be difficult for reaching comparatively accurate position.
The utility model content
The utility model provides a kind of stability higher high precision regulating device, solved in the past in the 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 utility model is that the 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 adjustment structure on the bracing frame, described adjustment structure comprises rotating shaft and is socketed in rotating disc in the rotating shaft, the circumference of rotating disc is provided with some cross bars, bracing frame is passed in described rotating shaft, and by threaded engagement, the lower end of rotating shaft is fixed with connector, is connected with the wiring rod on the connector between rotating shaft and the bracing frame.
Support frame as described above comprises two root posts of crossbeam and supporting traverse, and the bottom of column is bolted on the work top, and rotating shaft is vertically through crossbeam.
Be socketed with the support annulus in the rotating shaft between described rotating disc and the bracing frame, and the support annulus is fixed on the bracing frame.
Described rotating disc is provided with three cross bars, and three cross bars are positioned on the same level, and the angle between the adjacent crossbars is 120 degree.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) passes through threaded engagement between bracing frame of the present utility model and the rotating shaft, effectively reduced like this rocking that rotating shaft may occur, make whole Adjustment operation more stable.
(2) the utility model adopts cross bar to rotate rotating disc, because many cross bars being arranged, therefore in rotation process, can find a suitable cross bar of angle to rotate rotating disc, thereby make things convenient for adjusting, more easily obtains higher degree of regulation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
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, the wiring rod.
