The detection pin is 'Z'-shaped, and the tail of the detection pin is vertically connected with a sliding sleeve. The center calibration device for engine vibration experiment is skillful in manufacture, low in production cost and high in parts interchangeability. The labor is saved, the cost of engine experiment is effectively reduced, and the time for experiment preparation is shortened.
Description
technical field
The invention belongs to the detection frock field of auto parts and components, more particularly, relate to a kind of calibrate device of engine vibration experiment.
Background technology
Along with the development of auto industry, the research and development of new work engine type and new technology also gets the attention and payes attention to.For new architecture or new technology are verified, most engine producer has introduced dynamometer machine and supporting control device, threst stand is carried out to the output power of various simulated operations test engine.When engine is manually connected with dynamometer machine, the bad accurate judgement of the right alignment of both tie point positions, easily has deviation, thereby causes the fierce vibrations of body, and equipment is caused to damage.Traditional detection means, as dial gauge fixed point detection method, need to utilize dial gauge to adopt point analysis at the diverse location of engine flywheel, through repeatedly contrasting, determine again whether dynamometer machine keeps coaxial connection with engine, wastes time and energy and needs the sampling that operating personnel are very careful.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides a kind of calibrate device of engine vibration experiment, it is the calibrate device that a kind of detachable and capable of regulating detects length and radius, and make simple and easy, fitting operation is easy, without using exact instrument can reach testing requirement.
2, technical scheme
In order to address the above problem, the technical solution adopted in the present invention is as follows:
A kind of calibrate device of engine vibration experiment, comprise terminal pad, also comprise the fixed support, screw rod and the detection pin that set gradually, described terminal pad is made by circular steel plate, its middle part has the support fixed orifice that 4 rectangular shapes distribute, and on described terminal pad, away from center, has mounting hole; Described fixed support is fixed on terminal pad by nut and bolt, and it comprises threaded sleeve, sway brace and the fixed head from top to bottom setting gradually, and described sway brace has 2, the both sides of being fixed on threaded sleeve of both symmetries; Described fixed head has 2, is individually fixed in the bottom of sway brace, and described fixed head is rectangular-shaped structure, has 2 screw holes on it; The layout of the screw hole on described 2 fixed heads is identical with the support fixed orifice on terminal pad; Described screw rod is installed in threaded sleeve, and its one end is radially fixed with pointer slide bar; Described detection pin is " second " font structure, and its afterbody is vertically connected with sliding sleeve, and described sliding sleeve is " returning " font structure, itself and the sliding connection of pointer slide bar.
Further, described pointer slide bar is rectangular three-dimensional-structure; On described sliding sleeve one sidewall, have threaded hole, in described threaded hole, trip bolt is installed.
Further, the length of described sway brace is 70cm; Described detection pin is done by No. 45 steels, and its diameter is 3.3mm.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
The present invention adopts the screw mechanism cooperatively interacting to make test experience adapt at any time the required distance of dynamometer machine and engine and adjust at any time, needn't the new effort of duplicate removal move huge machinery and equipment; Between each parts, by nut and bolt, be fixed, dismounting at any time, detecting pin can change detection radius by sliding sleeve, and dirigibility is good; Its making is ingenious, production cost is low, interchangeablity is strong, has saved labour, effectively reduces engine test cost, has shortened the Preparatory work of experiment time.
