Not enough, and it is only capable of being detected tension device pointer position in engine inactive state, can not sentences at all in engine operation
The angle of disconnected throw of pointer.
Another kind is to judge dynamo belt side abnormal sound by the frequency that shakes of tread belt, so as to whether judge timing indirectly
Accurately：Frequency device is shaken close to belt by hand-held, reads the numerical value to shake on frequency device display screen.The shortcomings that this test mode is：
Frequency device needs are shaken close to dynamo belt test using hand-held, and accidentally, hand very likely touches belt injury；And survey
It is also not high to try accuracy.
Utility model content
The technical problems to be solved in the utility model is how to improve the accuracy of engine timing judgement, security, together
When also be detected during engine operation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of dynamo belt tension device and refers to
Hand position detecting device, it is characterised in that：Including the fixing bracket for being fixed on engine, fixing bracket, which is equipped with, to be used for
The graduation apparatus directly perceived for reading dynamo belt tension device throw of pointer angle；Graduation apparatus is set to 0 degree with 90 degree of vertical direction, 0
Spend the Digital ID that the right and left carries out positive negative angle；0 degree of position of initial quantization of dynamo belt tension device pointer and scale
0 degree of position on table coincides.
Preferably, the support bracket fastened thickness is 3~4mm.
Preferably, the support bracket fastened external form meets with starting machine outer type to match：Start when fixing bracket is fixed on
When on machine, fixing bracket will not transmit wheel with water pipe, the camshaft of engine, belt produces interference.
Preferably, the fixing bracket is equipped with for being passed through for bolt, so that the hole being fixedly connected with engine.
Preferably, the pore size on the fixing bracket is identical with the size of engine black mask housing hole.
Preferably, the graduation apparatus is set to 0 degree with 90 degree of vertical direction, is carried out in 0 degree of the right and left with 5 degree for a unit
Digital ID, and divided using 1 degree for a unit as minimum scale.
Preferably, the fixing bracket is equipped with multiple graduation apparatus, 0 degree of position of multiple graduation apparatus respectively with different type of machines
Dynamo belt expansion tightening wheel pointer 0 degree of position of initial quantization it is corresponding.
Device provided by the utility model overcomes the deficiencies in the prior art, can be installed on during engine operation
On engine, dynamo belt tension device hand motion section is detected, so as to judge whether engine timing is correct, keeps away
Exempt from that abnormal sound can be produced in engine long-play, avoid engine timing defect, play batch supervisory function bit.The present apparatus is tested
Accuracy is high, easy to operate, safe, suitably promotes the use of on a large scale.
Brief description of the drawings
Fig. 1 is dynamo belt tension device hand position testing device structure diagram provided in this embodiment.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
Fig. 1 is dynamo belt tension device hand position testing device structure diagram provided in this embodiment, described
Dynamo belt tension device hand position testing device is made of fixing bracket 1 and graduation apparatus 2.Graduation apparatus 2 is arranged in fixed branch
On frame 1, fixing bracket 1 is fixed on the engine, when engine operates, can intuitively read tension device throw of pointer angle,
Whether in the reasonable scope expansion tightening wheel beat of pointer amplitude is observed, so as to judge whether engine timing is correct, judges engine
Whether produce abnormal sound and help to find engine timing defect, play batch supervisory function bit.
Since the gap of engine expansion tightening wheel and envelope surface is small, therefore the thickness of fixing bracket 1 is designed as 3~4mm.Separately
Outside, measured according to engine appearance structure, by the exterior design of fixing bracket 1 into starting machine outer type to match, avoid and send out
Water pipe, the camshaft of motivation transmit wheel, belt produces interference.
Hole is provided with fixing bracket 1, for being passed through for bolt, so as to be fixed with engine.The hole ruler that fixing bracket 1 is hindered
It is very little be designed to it is identical with engine black mask housing hole size.To avoid fixing bracket 1 from dropping, the nut lock to match with bolt is used
Tightly.
Graduation apparatus 2 is set to 0 degree with 90 degree of vertical direction, and Digital ID is carried out with 5 degree for a unit in its right and left, and
Divided using 1 degree for a unit as minimum scale.Ensure that expansion tightening wheel can accurate readout value when swinging.
Simultaneously as the expansion tightening wheel pointer position of different type of machines is different, to improve the scope of application of this detection device, will examine
Survey on the fixing bracket 1 of device and be covered with graduation apparatus 2, to meet that the expansion tightening wheel pointer of different type of machines can be directly displayed at graduation apparatus
On, it is convenient directly to read.
The operation principle and the course of work of dynamo belt tension device hand position testing device provided in this embodiment are such as
Under：
In theory, no matter engine is in which rotating speed section, and expansion tightening wheel beat of pointer amplitude is compared to initial position for just
Minus 5 degree；Cooling backpointer returns to initial position.
Engine is initially mounted on testboard bay, and timing system is adjusted to piston top dead center, and take apart the engine upper end
After black mask shell, expansion tightening wheel pointer initial position is quantified as 0 degree, after 2 zero-bit of graduation apparatus on alignment and fixation stent 1, in cover
Shell bolt hole tightens fixing bracket 1 with 6mm bolts, examines expansion tightening wheel pointer initial position to be overlapped with 0 again, then uses 8Nm
Torque wrench belt tensioner hand position testing device is securely fixed, while use nut check.Ensure engine timing
System at work, makes device not loosened due to being influenced be subject to factors such as engine components vibrations, comes off.
Start engine, its adjustment of rotational speed to idling (830rmp) stablizes after ten minutes, whether observation tension device pointer
In the normal amplitude of fluctuation of detection device scale, accurately confirm whether tension device pointer is overproof, record amplitude of oscillation value one.Stop
Engine, re-records an amplitude of oscillation value two.Engine is formally acted as a travelling agent drained the oil before characteristic test before, screw back on engine piston
Dead-centre position, carries out the measure of amplitude of oscillation value three after cooling of all having drained the oil.So as to examine tension device pointer whether overproof, start
Whether machine cooling backpointer returns to initial position.And then help to judge that abnormal sound, the possibility of timing system defect occurs in engine.
