Abstract
The invention relates to an engine angular advance measuring tool. The engine angular advance measuring tool comprises a spacer bush, a supporting arm, a swinging arm and a measuring foot, the spacer bush is connected with the supporting arm through a fastening bolt, a long hole is arranged in the middle of the supporting arm, and the fastening bolt and a bolt are mounted in the long hole. The supporting arm is connected with the swinging arm through the bolt, a long hole is mounted in the middle of the swinging arm, and the swinging arm is connected with the supporting arm through the bolt in the long hole. The measuring foot is arranged at the lower end of the swinging arm. According to the engine angular advance measuring tool, an engine front cover is used as a carrier to fix the tool, then turning is performed to an engine, a cylinder top dead center is found out, a line can be accurately marked on a belt pulley by a cutting head (the measuring foot) in front of the cylinder top dead center, an angular advance of a fuel injection pump is figured out according to the length of the marked line, the error rate of reading is reduced, and the measurement accuracy is improved.
Description
Technical field
The present invention relates to a kind of advance angle of engine survey instrument.
Background technology
At present, in the Engine Matching test, the coupling of injection pump is one of most important work, because the difference of environment for use, performance to engine has different demands, for the attainment of one's purpose, injection pump often will be sought an ideal state in the state of a lot of angle of advance, therefore tends in test carry out the performance comparison test of multiple angle of advance.If determine the method for angle of advance according to this tradition, not only time-consuming but also effort, and also measured angle of advance also exists error.
Summary of the invention
The objective of the invention is provides a kind of simple in structure for solving the technical matters that exists in the known technology, can reduce the error rate of reading, improves the advance angle of engine survey instrument of measuring accuracy.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
A kind of advance angle of engine survey instrument comprises spacer, sway brace, swing arm and measurement pin, and described spacer connects sway brace by fastening bolt, and described sway brace is bolted swing arm, and the lower end of described swing arm is provided with the measurement pin.
The middle part of described sway brace is provided with slotted hole, and fastening bolt and bolt all are arranged in the slotted hole.
The middle part of described swing arm is provided with slotted hole, connects sway brace by the bolt in the slotted hole.
Advantage and good effect that the present invention has are: utilize engine front cover to be fixed as carrier of the present invention, then engine is carried out jiggering, find out a cylinder after top dead center, utilize the cutter head (measurement pin) of its front to rule at belt pulley accurately, then calculate the angle of advance of injection pump according to the length gauge of groove, reduce the error rate of reading, improved measuring accuracy.
Description of drawings
Fig. 1 is that the present invention partly cuts open structural representation;
Fig. 2 is that the present invention uses the status architecture synoptic diagram;
Among Fig. 1 and Fig. 2,1. spacer, 2. protecgulum, 3. sway brace, 4. swing arm is 5. measured pin, 6. scale, 7. belt pulley.
Embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of advance angle of engine survey instrument, comprise spacer 1, sway brace 3, swing arm 4 and measure pin 5, spacer 1 connects sway brace 3 by fastening bolt, in order to make the sway brace 3 can move left and right, the middle part of sway brace 3 is provided with slotted hole, fastening bolt is installed in the slotted hole, also be provided with bolt in the slotted hole, sway brace 3 is bolted swing arm 4, can move up and down in order to make swing arm 4, and the middle part of swing arm 4 is provided with slotted hole, so just can pass through adjusting bolt, swing arm 4 can be moved up and down.Be installed with measurement pin 5 in the lower end of swing arm 4.By regulating portrayal line cutter head, realized that different type of machines, many kinds all can use the same survey instrument.
Utilize engine front cover 2 to be fixed as carrier of the present invention, then engine is carried out jiggering, find out a cylinder after top dead center, utilize the cutter head (measuring pin 5) of its front to rule at belt pulley 7 accurately, then calculate the angle of advance of injection pump according to the length (scale 7 is measured) of groove, reduce the error rate of reading, improved measuring accuracy.
The invention solves angle of advance zero degree groove and belt pulley not in the problem of a reference plane, solved the problem that there is error in when measuring angle of advance reading, improved the precision of measuring.
More than record, only for utilizing the embodiment of this origination techniques content, modification, variation that any the technology person of being familiar with uses this creation to do all belong to the claim that this creation is advocated, and are not limited to those disclosed embodiments.
