Description
Technical field
The invention belongs to motorcycle engine external characteristics experimental technique field, refer in particular to outside a kind of motorcycle engine board plug type
Attribute testing frame.
Background technique
Small-displacement engine of motorcycle is the main component of motorcycle, and the superiority and inferiority of engine performance determines the matter of motorcycle
Amount is wanted to produce high-quality cheap engine it is necessary to carry out effective revolving speed, torsion to engine in engine each development phase
Square, power, fuel consumption rate, oil temperature etc. carry out external characteristics test, and the test of development phase includes: 1. to come out in blank
Afterwards, it needs to carry out in detail and accurately external characteristics test model machine, to verify whether performance and the reliability of complete machine reach design
It is required that while examine the reliabilities of each components, and by this process, to be improved to engine, and engine
Improvement is the troubleshooting process in test to complete；2. no matter how Cheng Shu engine, be all by continuously improving
To adapt to the mating demand of motorcycle；3. carrying out technical examination to mature engine product to improve each details, make it
It is more perfect；4. engine key components and parts and important spare part determine the performance of engine, to key components and parts with it is important
Components carry out the examination no less important of examination with complete machine；5. the components for needing to examine to detection unit carry out relevant examination
It tests, then disassembles, examines, analysis, even more improving the important means of components quality.
Above-mentioned engine development stage needs so more external characteristics tests, and the test in each stage require first to make with to
Then the adaptable test stand of the engine of test carries out external characteristics test so that engine to be fixed on test stand.Originally
Using traditional rack-mounted machine of welding type right-angled, weight is big, and more people is needed to move, and when taking turns to night test, the few just lift of people on the scene is not
It is dynamic.People can only be looked for lift to test stand on dynamometer machine in advance, then engine is installed again carry out external characteristics test, encounters replacement not
When with model engine, adaptable test stand can only be replaced, or purchases several dynamometer machines to meet test needs more.
Later in order to which the number for reducing frequently carrying test stand machined more hole and escape groove, on test stand to adapt to
More engine kind.After the engine kind of test increases, these hole slots will be crushed connection, in order to not influence passing through
The assembly of bolt is worn, can be made up by large washer, but dowel hole must completely, otherwise will affect positioning accurate
Degree.After the kind of test further increases, dowel hole can just be bored without position, continue to test, it is necessary to replacement test
Frame.In addition, vibration is larger because right angle frame can only be unilateral fixation, test mass is influenced.
Summary of the invention
The object of the present invention is to provide a kind of easy to loading and unloading, can significantly reduce labor intensity, reduces auxiliary install the time, mention
The motorcycle engine board plug type external characteristics test stand (letter that high working efficiency, reduction shake, have a safety feature, can respectively disassemble
Claim test stand, under address the application alternative document it is all the same), when the pin hole of the engine mounting plate in test stand is not enough
When, it, can be by trial stretch batch dilatation again as long as more reengining mounting plate.
The object of the present invention is achieved like this:
Test stand is by bottom plate, fixed frame, engine mounting plate, vent ribs plate, crankshaft shaft coupling, reinforcing washer, sky
Heart positioning pin, bottom surface band tongue-and-groove briquetting, flat key material pressing plate, equal height cushion block, external reinforcing ribs plate, interior stiffener plate, side band tongue-and-groove
Briquetting, internal screw thread taper knob and fastener composition.
Test stand is with fabricated structure, and instead of bulky welding type right-angled frame structure, advantage is, easy to make, and common is small
Type Metal Cutting Machine Tool can be completed, a frame multipotency, reduces the demand to dynamometer machine quantity, reduces occupied area, mitigates
Labor intensity improves detection quality when shortening the equipment beam worker of experiment work early period.The most ready-made material of the present invention
Material, simplest processing method, minimum cost solve the technology that people thirst for solution but do not break through always for a long time
Problem arranges and fixes quotas to control production convenient for examining, has substantive distinguishing features outstanding and significant progress.
There are also following distinguishing features by the present invention:
For the bottom plate of test stand other than controlling thickness, bottom surface is formed with down counterbore, is tensed by hexagon socket cap head screw
Fixed frame and vent ribs plate and inside and outside stiffener plate.
The fixed frame of test stand is also tapped with three groups of screw holes, first group of screw hole is under other than controlling the width of three bar grooves
Face is used as hexagon socket cap head screw connection bottom plate, and second group of screw hole is above, as bottom surface band tongue-and-groove briquetting and side band
Engine mounting plate is fitted in the sub-assembly of fixed frame and bottom plate by tongue-and-groove briquetting by hexagon socket cap head screw, third group
Screw hole is in the interior outside of fixed frame, by interior hexagonal flush end holding screw come auxiliary jacking engine mounting plate.
The engine mounting plate of test stand, mainly control thickness, can smoothly be inserted into fixed frame, start to relevant
The corresponding position of machine contact, is formed with the evacuation pit slot of various engines projecting member, and also there are three types of holes for system, the first is position degree
Exigent dowel hole, second is bolt-through hole, the third is the screw hole for coupling taper knob.
The screw hole there are two types of different directions is attacked in the vent ribs of test stand and inside and outside reinforcing rib, one kind passing through interior six
Angle fillister head screw is fixed on bottom plate, and another kind is coupled with engine mounting plate by hexagon socket cap head screw, to starting
Machine mounting plate plays booster action.
The crankshaft shaft coupling of test stand, small end are coupled by the spline housing in shaft coupling with the crankshaft of tested engine, greatly
End is coupled by the pawl foot of shaft coupling with the baffle-box of dynamometer machine, and semiclosed form is made in coupling claw foot, is remarkably improved connection
The service life of axis device.
The bottom surface band tongue-and-groove briquetting of test stand is fitted in engine mounting plate side by side in a manner of micro- interference fit
Between window, to reduce the vibration of engine mounting plate during the test.
The side band tongue-and-groove briquetting of test stand clamps the left and right sides of engine mounting plate in a manner of micro- interference fit,
Play the role of reinforcing engine mounting plate.
