Description

Motorcycle six fast engine measurement of power and intensification clamps

Technical field

The utility model relates to anchor clamps, in particular for the anchor clamps of the stationary engine of the power measurement of motorcycle six fast 250ml displacement engines and strenuous test.

Background technology

In the motorcycle six fast 250ml displacement engine production runes, need carry out sampling Detection, whether stablize, find its quality problems to determine its performance to its performance.Power measurement in the performance test, strenuous test are most important Performance Detection, need on the worktable of special use, engine to be measured be fixed during test, the discharge capacity of six fast 250ml displacement engines is bigger, thereby volume is also big, from great, vibration damages in test engine strongly easily in the engine operation process, thereby causes test inaccurate, need be at its design feature, the anchor clamps of the stationary engine of design specialized.

The utility model content

The purpose of this utility model is: a kind of motorcycle six fast engine measurement of power and intensification clamps are provided, satisfy the needs of measurement of power and strenuous test, have shock-absorbing function protecting tested engine, and want convenient mounting and clamping.

Motorcycle six fast engine measurement of power and intensification clamps of the present utility model, its scheme is: it is made of main support and auxiliary stand; Main support is: a rebound is installed on the big base plate of body frame of a level, separate with the vibration damping rubber cushion between big base plate of body frame and the rebound, a pair of high trestle and a pair of short support are fixed on the rebound, the spacing and the engine suspension point of every pair of support are suitable: hanging hole is set on the high trestle and disposes a big pull bar, the front overhang hanging point of engine is passed and is hanging in the hanging hole of above-mentioned two high trestles during work by big pull bar; Hanging hole also is set on the short support and disposes a lower link bar, the aft hook of engine is passed and is hanging in the hanging hole of above-mentioned two short supports during work by lower link bar; Big pull bar, lower link bar are screw rod, use the nut lock engine; Auxiliary stand is: erect on the big base plate of pull bar a riser is set, the riser upper end is the steady brace set square again, the top position that the pull bar set square reaches main support is provided with a hinge, by cylinder head pull bar of elastic rubber sleeve assembling, the cylinder head pull bar has the pin of extension to be used for hanging the engine cylinder head hitch point in the hinge.The elastic damping gum cover that is connected with vibration damping rubber cushion and cylinder head pull bar between the big base plate of body frame and the rebound; make engine be in a kind of damping environment operation down of flexibility; the protection engine is not damaged, and avoids engine output shaft because of the excessive test error that brings of beating yet.

High trestle, short support is in order to bear the main weight of engine above engine is hung over, add auxiliary stand, just simulated the hang of engine reality, its hang respectively engine before, aft hook and cylinder head hitch point, the spacing of two high trestles or two short supports is generally engine suspension point width, other clampings and assemblage gap sum, say engine lifting aligning high trestle during installation earlier, insert big pull bar, lift rolling motor again and aim at short support, insert lower link bar, use the nut screwing clamping stationary engine, last, the cylinder head hitch point of engine hung on the auxiliary stand get final product.

High trestle described in the scheme and short support can weld the stand drafting board respectively, the hanging hole of processing on the stand drafting board is a threaded hole, the screw thread gland of high trestle and the screw thread gland of short support are installed in the above-mentioned threaded hole, screw thread gland end face chucking engine when large and small pull bar is used nut lock.The screw thread gland can be faced the engine orientation distance in the adjustable side, and regulates assemblage gap, changes with the size of engine that satisfies different batches.At this moment the spacing of two high trestles or two short supports is that engine suspension point width, screw thread gland device stretch out and the assemblage gap sum, utilize screw thread gland location engine and thread to clamp, accurate positioning, simple in structure, the clamping force that screw thread produces is big and reliable, only need unclamp nut when taking off engine and extract pull bar out, convenient mounting and clamping, easy and simple to handle.

Above-mentioned high trestle and short support can be welded to respectively on the main support platter, are screwed the mode on rebound again.After the biside plate assembling that this mode can compare precision higher is finished, be welded on the riser convenient the manufacturing again.

The rubber cushion of vibration damping described in the scheme can be 4, is separately positioned on the below of a pair of high trestle and a pair of short support.

Hinge described in the scheme can be U type hanger of pull bar set square welding, the axial line and the forward and backward hitch point axis parallel of engine of hinge swing, the cylinder head pull bar is: front tension bar and back stay axially are processed with the opposite threaded hole of rotation direction, connect with the double thread post, front tension bar is provided with the drawhead of band U type hangers, join in the pin-and-hole of drawhead and hang pin, back stay welding axle sleeve, axle sleeve is enclosed within on the elastic rubber sleeve, with screw rod is that axle is installed on the U type hanger the forward and backward hitch point axis parallel of the axial line of swing and engine.The cylinder head pull bar is the reverse screw mandrel of double end, can regulate the distance of support easily, make cylinder head be subjected to best vibration reduction restriction, the axial line and the forward and backward hitch point axis parallel of engine of swing, avoid because of suppending hole damage behind the excessive engine that causes of cylinder head Oscillation Amplitude, cause and detect test termination failure midway, this mode can be regulated the mode of the length of cylinder head pull bar and be regulated the tightness of straining the engine cylinder head hitch point, change the natural frequency of engine, reach best damping effect.Simple in structure effective.

The utility model has the advantages that: utilize the forward and backward hitch point of engine and cylinder head hitch point to carry out clamping; the effect that when measuring power and carrying out strenuous test, has the simulation virtual condition; measurement data is more accurate; the measures such as elastic rubber sleeve that damping rubber cushion and cylinder head pull bar connect reduce vibration; protect tested engine, clamp, regulate, can operate by hand with screw thread; simple in structure, easy and simple to handle, convenient mounting and clamping.
