Description
Technical field
The utility model relates to a kind of motor car engine and measures cubing, particularly a kind of combustion-chamber depth measurement mechanism.
Background technology
In cylinder, when the piston is at the top dead center, the space formed more than piston-top surface, below cylinder head bottom surface is called firing chamber.Usually be cast with different pit in cylinder cover of petrol engine bottom surface and form firing chamber, combustion-chamber shape and the degree of depth are the principal elements determining burning rate, prevent malcombustion.The cylinder head roughing standard face that combustion-chamber depth refers to is to the height of firing chamber measurement point, and cylinder head roughing standard face is positioned at inside cylinder head bottom surface, higher than cylinder head bottom surface.
The Chinese patent CN202345559U that on June 30th, 2010 is announced, name is called detecting tool for detecting height of engine cylinder head and combustion chamber, and this device is made up of calibration body and measurement body; Described calibration body comprises base plate, base plate is equipped with in several benchmark boss tandem and calibration boss, described measurement body comprises web joint, the spacing benchmark boss corresponding with the benchmark lug boss position of calibration body is housed under web joint, web joint is equipped with the dial gauge corresponding with the calibration lug boss position of calibration body.This device utilizes spacing benchmark boss to locate on cylinder head roughing standard face, then utilizes dial gauge to fathom to firing chamber measurement point.And in actual production process, after combustion-chamber depth is determined, combustion chamber volume is indirectly ensured by the distance between firing chamber measurement point and cylinder head bottom surface, therefore, the height of measurement point distance cylinder head bottom surface, firing chamber is also the important parameter needing monitoring, this parameter, after combustion-chamber depth measurement completes, also can obtain to cylinder head floor height by measuring cylinder head roughing standard face indirectly.Said apparatus obviously can only measure the height of firing chamber, and cannot ensure the height of measurement point distance cylinder head bottom surface, firing chamber.The thick embryo of cylinder head is adding man-hour, if above-mentioned two parameters are overproof and can not Timeliness coverage, when follow-up cylinder cover bottom surface finishing, process redundancy fluctuation is large, finally cause because of combustion chamber volume and cylinder cap thickness is overproof and overall cylinder cover is scrapped, meanwhile, also can increase cutter consumption and man-machine waste.
Summary of the invention
The purpose of this utility model is to measure for existing combustion-chamber depth the problem that cubing cannot obtain firing chamber measurement point distance cylinder head floor height, a kind of combustion-chamber depth measurement mechanism is provided, combustion-chamber depth and firing chamber measurement point distance cylinder head floor height can be detected simultaneously.
The utility model solves the technical scheme that its technical matters adopts: a kind of combustion-chamber depth measurement mechanism, comprise substrate, substrate bottom surface has at least three reference pins of locating with cylinder head roughing standard, for plugging the orienting sleeve of meter, described orienting sleeve comprises with position, each firing chamber that the top of orienting sleeve A, several orienting sleeve B corresponding with multiple position, cylinder head bottom surface, orienting sleeve B and the tip height difference of orienting sleeve A are the design difference of cylinder head bottom surface and firing chamber measurement point one to one.This device, after the origin reference location of cylinder head roughing standard face, can detect the degree of depth of each firing chamber in orienting sleeve A position by meter, also can detect the height of cylinder head bottom surface to firing chamber measurement point at orienting sleeve B position multiple spot.The qualification rate of cylinder head combustion chamber volume is ensured by the detection of two parameters.Eliminated the difference of reading of orienting sleeve A and orienting sleeve B measuring position by the elemental height setting of orienting sleeve A and orienting sleeve B, make orienting sleeve A and orienting sleeve B place that same meter can be adopted to carry out unifying reading.During detection, on each orienting sleeve, all meter can be set, single meter also can be adopted to measure the reading of each orienting sleeve one by one.
As preferably, described orienting sleeve B is respectively equipped with two at the dual-side of corresponding cylinder head length direction, is respectively equipped with one at the dual-side of corresponding cylinder head Width.By detecting the multiple spot of cylinder head periphery, guarantee the qualified of each position, cylinder head bottom surface.
As preferably, described substrate is also provided with the register pin corresponding with cylinder head bottom surface pin-and-hole.
As preferably, described substrate bottom surface is respectively equipped with limiting plate on the dual-side of Width and one of them side of length direction.When limiting plate contributes to measuring, cubing is located rapidly, makes detection more convenient.
As preferably, described limiting plate bottom outwards launches to form guide frame.
As preferably, also comprise a calibration module, described calibration module be upper end open, sleeve that bottom surface is closed, skirt depth is the degree of depth of orienting sleeve A end face distance firing chamber measurement point.Meter can carry out calibration zero setting in calibration module.
The utility model adopts a set of measurement mechanism, simultaneously detect combustion-chamber depth and firing chamber measurement point distance cylinder head bottom surface height, by one-time detection guarantee the combustion-chamber depth of cylinder head and combustion chamber volume qualified.
