Description
Technical field
The invention belongs to car engine machine check frock, and in particular to a kind of engine timing system checks frock and side
Method.
Background technology
At present, car engine timing system checks that purpose is：Judge phase corresponding to camshaft, bent axle whether just
Really, timing system failure is investigated.
The step of existing timing system is checked includes：
（1）The part for coating timing system is disassembled one by one；Due to the phaser or gear, the song that are connected with intake and exhaust cam axle
Axle or crankshaft sprocket are connected with chain each other, therefore rotate the bent axle in timing system, and correlated parts can follow rotation；
（2）The bent axle in timing system is rotated, observation is arranged on the phaser or gear being connected with intake and exhaust cam axle
Timing marks be arranged on it is whether corresponding with the timing marks on the chain that phaser or gear are connected；Observation is arranged on and phase
Timing marks on position device or the chain that is connected of gear whether be arranged on the bent axle or crankshaft sprocket being connected with chain
Timing marks whether correspond to.
This kind of method needs one by one to disassemble the part for coating timing system, because whole process of disassembling is complicated, increased
The workload that timing system is checked.Also can result in the parts cleanliness reduction for dismantling.In addition, in order to ensure timing system
Sealing in the process of running, its cladding part needs gluing or shimming.Disassemble with assembling process if blade coating
Glue is unsatisfactory for requiring or pad sealing performance reduction, it will causes poorly sealed, permeability situation occurs.
Therefore, it is necessary to developing a kind of new engine timing system checks frock and method.
The content of the invention
Frock and method are checked it is an object of the invention to provide a kind of engine timing system, the leakage of timing system can be reduced
Alopecia areata danger, can improve operating efficiency.
Engine timing system of the present invention checks frock, including crank position fixture and camshaft phase inspection
Part；
The crank position fixture includes that crank position fixes body, and the one end for fixing body in crank position is provided with and signal
The boss that breach on plate edge is engaged, the top surface for fixing body in crank position is provided with convex for fix crank position
Block；
The camshaft phase checks that part is the cylinder body of bottom end closure, and step, and cylinder are provided with the top of cylinder body
The bottom of body is made of transparent material, and is marked on the bottom of cylinder body useful in the quarter for checking camshaft location
Degree.
Direction is downward-sloping from the inside to the outside for the top surface of the boss.
A kind of engine timing system inspection method of the present invention, using engine timing system of the present invention
Frock is checked, its method is comprised the following steps：
Step one, turning crankshaft, make the signal panels being arranged on bent axle turn to predeterminated position, by the insertion of crank position fixture
It is arranged in the crankshaft position sensor mounting hole on crankcase, and the boss on crank position fixture is stuck in signal panels
On breach, while the projection of crank position fixture is stuck in crankshaft position sensor mounting hole fixes the position of bent axle；
Step 2, camshaft phase inspection part is inserted into camshaft signal sensor mounting hole, and alignment cam axle phase
Disk；
Step 3, rotation camshaft phase check part, the scale above it is put down with the signal teeth edge on camshaft phase disk
OK, whether the signal teeth edge on camshaft phase disk is checked in meter full scale, if, then it is assumed that timing system is normal, if
It is no, then it is assumed that timing system is abnormal.
Beneficial effects of the present invention：When being checked engine timing system using the present invention, it is only necessary to disassemble bent axle
Position sensor and CMPS Camshaft Position Sensor, therefore the workload of part is disassembled in reducing timing system checking process, reduce
The oil leak risk of timing system, improves operating efficiency, the present invention suitable for engine monomer assays and maintenance process just
When systems inspection work.

Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Engine timing system as shown in Figures 1 to 6 checks frock, including crank position fixture 4 and camshaft phase
Position checks part 8.
As shown in figure 4, the crank position fixture 4 includes that crank position fixes body 43, this is fixed in crank position
One end of body 43 is provided with the boss 41 being engaged with the breach on the edge of signal panels 1, the top surface of the boss 41 direction from the inside to the outside
It is downward-sloping, in facilitating the breach that boss 41 is inserted on the edge of signal panels 1.The top surface for fixing body 43 in crank position is provided with
For the projection 42 for fixing the position of bent axle 2.
As shown in Figure 5 and Figure 6, the camshaft phase checks that part 8 is the cylinder body 81 of bottom end closure, in cylinder body
81 top is provided with step 82, and the bottom of cylinder body 81 is made of transparent material, and on the bottom of cylinder body 81
It is marked with the scale 10 for checking the position of camshaft 7.
A kind of engine timing system inspection method of the present invention, using engine timing system of the present invention
Frock is checked, its method is comprised the following steps：
Step one, as shown in figure 1, turning crankshaft 2, the signal panels 1 being arranged on bent axle 2 is turned to predeterminated position（That is Fig. 1 institutes
