Abstract
The utility model discloses a kind of corner marking instrument stationary installation, it comprises corner marking instrument catheter holder, corner marking instrument adapter flange and corner marking instrument, wherein, described corner marking instrument catheter holder is fixed on engine body, described corner marking instrument adapter flange is fixed on the crank pulley on engine body, described corner marking instrument to be fixed on corner marking instrument adapter flange by joint flange and coaxial with engine crankshaft, and the conduit of described corner marking instrument is fixed on corner marking instrument catheter holder.Above-mentioned corner marking instrument stationary installation connects the crank pulley on corner marking instrument and engine body by corner marking instrument adapter flange, is fixed the conduit of corner marking instrument simultaneously, make corner marking instrument not produce swing offset by corner marking instrument catheter holder; Not only ensure that the right alignment of corner marking instrument and engine, make the accuracy of measurement engine compresses top dead centre higher; And ensure that the serviceable life of corner marking instrument.
Description
Technical field
The utility model belongs to automotive engine test field, particularly relates to a kind of corner marking instrument stationary installation for car engine rack test.
Background technology
When engine rig test, Combustion tester is used to need corner marking instrument is installed, because the physical dimension of corner marking instrument and installed surface just cannot be changed when dispatching from the factory, and the physical dimension of engine crankshaft belt pulley just cannot be changed when dispatching from the factory, and these two parts do not form unified standard, so corner marking instrument cannot be directly installed on crank pulley in standard now.
At present, corner marking instrument is installed and normally on crank pulley, directly beats several bolt hole supporting with corner marking instrument mounting flange, then directly corner marking instrument is fixed, such fixing means, first be difficult to ensure in the right alignment of corner marking instrument and engine, thus the accuracy of engine compresses top dead centre is measured in impact, corner marking instrument more can be made to occur diameter run-out, thus affect the serviceable life of corner marking instrument.
Utility model content
The purpose of this utility model is to provide a kind of corner marking instrument stationary installation, with solve the measurement accuracy difference that exists in corner marking instrument fixed sturcture in prior art and corner marking instrument serviceable life short problem.
For reaching this object, the utility model by the following technical solutions:
A kind of corner marking instrument stationary installation, it comprises corner marking instrument catheter holder, corner marking instrument adapter flange and corner marking instrument, wherein, described corner marking instrument catheter holder is fixed on engine body, described corner marking instrument adapter flange is fixed on the crank pulley of engine body, described corner marking instrument to be fixed on corner marking instrument adapter flange by joint flange and coaxial with engine crankshaft, and the conduit of described corner marking instrument is fixed on corner marking instrument catheter holder.
Especially, described corner marking instrument catheter holder entirety is in " Z " type structure, and its one end is fixed on described engine body by set bolt, and the other end offers fixed orifice, and the conduit of described corner marking instrument is fixed on corner marking instrument catheter holder through described fixed orifice.
Especially, described corner marking instrument adapter flange is fixed on the crank pulley of engine body by set bolt.
Especially, described joint flange is fixed on described corner marking instrument adapter flange by set bolt.
The beneficial effects of the utility model are, compared with prior art described corner marking instrument stationary installation connects the crank pulley of corner marking instrument and engine body by corner marking instrument adapter flange, fixed the conduit of corner marking instrument simultaneously by corner marking instrument catheter holder, make corner marking instrument not produce swing offset; Not only ensure that the right alignment of corner marking instrument and engine, make the accuracy of measurement engine compresses top dead centre higher; And ensure that the serviceable life of corner marking instrument.
Accompanying drawing explanation
Fig. 1 is the side view of a kind of corner marking instrument stationary installation that the utility model embodiment 1 provides;
Fig. 2 is the upward view of a kind of corner marking instrument stationary installation that the utility model embodiment 1 provides.
In figure:
1, corner marking instrument catheter holder; 2, corner marking instrument adapter flange; 3, corner marking instrument; 4, engine body; 5, conduit; 6, crank pulley; 7, joint flange.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of corner marking instrument stationary installation comprises corner marking instrument catheter holder 1, corner marking instrument adapter flange 2 and corner marking instrument 3, described corner marking instrument 3 is for measuring and recording engine one cylinder compression top center, described corner marking instrument catheter holder 1 entirety is in " Z " type structure, its one end is fixed on engine body 4 by set bolt, the other end offers fixed orifice, the conduit 5 of described corner marking instrument 3 is fixed on corner marking instrument catheter holder 1 through described fixed orifice, does not produce swing offset to make corner marking instrument 3.Described corner marking instrument adapter flange 2 is fixed on the crank pulley 6 of engine body 4 by set bolt, described corner marking instrument 3 is installed on joint flange 7, and described joint flange 7 to be fixed on corner marking instrument adapter flange 2 by set bolt and coaxial with engine crankshaft.
When the crank pulley 6 of above-mentioned engine body 4 rotates, drive corner marking instrument adapter flange 2 to rotate, and then drive the corner marking instrument 3 on joint flange 7 to rotate by corner marking instrument adapter flange 2.
Above embodiment has just set forth ultimate principle of the present utility model and characteristic; the utility model does not limit by above-mentioned example; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
