Abstract
The utility model discloses a balance shaft static balance calibrating device, comprising a bearing. On the bearing are paved supporting columns parallel to each other. On the supporting columns is provided, in a flatwise manner, a balance shaft capable of freely rolling on the supporting columns. The front of the balance shaft is fixedly sleeved with a balance beam base on which is fixedly mounted a balance beam slidingly sleeved with a weight. The upside position of the balance shaft neck is provided with a dial base mounted on the bearing. On the dial base is installed a dial and the balance shaft is provided with pointers cooperating with the dial. The utility model is convenient, reliable and highly accurate in the calibration of the unbalanced moment of the balance shaft. Meanwhile, the utility model is not high in manufacture cost, easy in structure, convenient in operation and easy in processing and manufacturing and is applicable to control the quality of balance shaft products for small and medium enterprises.
Description
Technical field:
The utility model relates generally to and is used for the device that diesel engine balancing shaft process is carried out the static equilibrium verification.
Background technology:
The diesel engine balancing shaft is to be used for the formed reciprocal moment of inertia of balance diesel engine piston connecting rod, in order to reduce engine luggine, reduces the noise of engine, prolongs engine a kind of project organization in serviceable life.The engine that mainly is non-full balances such as single cylinder to four cylinder adopts this structure.The balancing shaft structure most important is eccentric, because of the eccentric barycenter distance that produces, balances each other by the moment of inertia of motion generation and the reciprocal inertia force square of engine.Therefore the balancing shaft barycenter directly affects the effect of engine balance apart from the size of (unbalanced moments).So the control to the unbalanced moments of balancing shaft own has just become whole balance system of engine key of success.
Balancing shaft is with respect to other key components of diesel engine, and structure is simple relatively, and processing dimension is control easily also.The material of balancing shaft mainly is a foundry goods, when casting, have casting flaws such as shrinkage porosite, pore, in order to reach counterbalance effect, minimizing is because of balancing shaft unbalanced moments deficiency, and cause the fully moment of inertia that in motion process, produced such as balance piston of engine, balancing shaft needs balancing shaft is carried out the static equilibrium verification in process, determines whether the unbalanced moments of balancing shaft adheres to specification.Equally, when engine assembled, we also will carry out incoming inspection to the balancing shaft unbalanced moments, control the unbalanced moments of balancing shaft.Balancing shaft and flywheel, emery wheel rotary member difference, its theoretical barycenter will make the balancing shaft barycenter be transferred on the balancing shaft axial line so balancing shaft is carried out the static equilibrium verification not on shaft center line, utilize special static equilibrium calibration equipment.
The utility model content:
The utility model purpose is exactly for a kind of balancing shaft static equilibrium calibration equipment is provided, and is more convenient, reliable during its verification balancing shaft unbalanced moments, accuracy is high, and manufacturing cost is not high simultaneously.
The utility model is achieved through the following technical solutions:
Balancing shaft static equilibrium calibration equipment, include bearing, it is characterized in that: be equipped with the support column that is parallel to each other on the bearing, kept flat free rolling balancing shaft thereon on the described support column, balancing shaft front end fixed cover is equipped with arm beam of steelyard seat, be installed with the arm beam of steelyard on the arm beam of steelyard seat, the described arm beam of steelyard be positioned at balancing shaft on scallop divide relative position, slip cap is equipped with sliding weight of steelyard on the described arm beam of steelyard; Described balancing shaft axle journal upper position is equipped with the dial plate seat and is installed on the bearing, on the described dial plate seat dial plate is installed, and the pointer that cooperates with dial plate is installed on the described balancing shaft.
Described balancing shaft static equilibrium calibration equipment is characterized in that: be with lining on the described support column, described balancing shaft is pressed on the described lining.
Apparatus of the present invention design concept is the steelyard principle, promptly rely on sliding weight of steelyard moving on the arm beam of steelyard, come the unbalanced moments of " scale goes out " balancing shaft, according to content shown in the pointer angle pointed and the arm beam of steelyard, cooperate corresponding balancing shaft to remove heavy drill jig, can effectively control the unbalanced moments of balancing shaft, make the balancing shaft of producing meet the drawing requirement.
Concrete checking procedure is as follows: earlier balancing shaft is placed on the support column, requires balancing shaft can roll freely on support column.The flabellum of balancing shaft automatically down under the free state.Then, the arm beam of steelyard is contained in it on balancing shaft front end with flat key together with arm beam of steelyard seat, rotates the arm beam of steelyard and make the flabellum of balancing shaft turn to horizontal level, at this moment, pointed dial plate zero graduation is inserted in sliding weight of steelyard on the arm beam of steelyard then, and the sliding weight of steelyard position is placed on " 0 " scale mark position on the arm beam of steelyard.When pointed dial plate position is not on " 0 " scale when sliding weight of steelyard is on " 0 " scale, illustrate that balancing shaft moment does not meet designing requirement.According to the indicated angle of pointer, can know the angle position of balancing shaft barycenter.Sliding weight of steelyard is moved on the arm beam of steelyard, make on " 0 " scale mark of pointed dial plate, at this moment,, can calculate balancing shaft unbalanced moments and designing requirement what differ according to the groove number that sliding weight of steelyard moves relative to " 0 " groove on the arm beam of steelyard.Because the barycenter of balancing shaft in a balancing shaft flabellum left side or right both sides, needs in the time of can measuring the balancing shaft barycenter apart from the position to adjust the moment of the left and right sides position finding balancing shaft of the arm beam of steelyard according to the balancing shaft rotation situation.Just can handle balancing shaft easily by above gained data.
As long as the utility model cooperates corresponding balancing shaft to remove heavy drill jig according to content shown in the pointer angle pointed and the arm beam of steelyard, can effectively control the unbalanced moments of balancing shaft, makes the balancing shaft of producing meet the drawing requirement.
The utility model has the advantages that:
The utility model is convenient when verification balancing shaft unbalanced moments, reliable, accuracy is high, and manufacturing cost is not high simultaneously.Have simple in structure, easy to operate, the easy advantage of processing and manufacturing, suitable medium-sized and small enterprises are used for controlling the balancing shaft product quality.
