Abstract

The utility model discloses a detection device for measuring the depth of the oil injector mounting hole of a diesel engine cylinder cap. The detection device comprises a positioning core axle, wherein a measuring rod capable of moving up and down freely is arranged in the positioning core axle, the positioning core axle and the mounting hole are in clearance fit, the positioning core axle and the measuring rod are in clearance fit, and the upper part of the positioning core axle is in thread connection with a dial gauge support for fixing a dial gauge. In depth measurement, a cylinder cap junction surface is in bonding contact with a detection platform, the positioning core axle and the measuring rod are inserted into the oil injector mounting hole respectively, and the measuring rod center contacts the detection platform so as to drive the dial gauge on the dial gauge support for movement, thereby reading out depth value.

Description

Mounting hole of oil sprayer depth survey cubing
Technical field
The utility model relates generally to and is used for cylinder cover for diesel engine mounting hole of oil sprayer depth survey cubing.
Background technology
The mounting hole of oil sprayer of cylinder cover for diesel engine and cylinder head plane inclination certain angle are simultaneously with cylinder centerline inclination certain angle.The machining precision of this mounting hole can influence engine combustion chamber shape and complete machine ratio of compression, performance to whole engine has direct influence, but because the special shape of this mounting hole, working depth can not directly be measured, the crudy that how to guarantee and detect such hole is to have great significance to the quality and the performance of cylinder head product, and we have invented mounting hole of oil sprayer depth survey cubing in order to measure the working depth in this hole for this reason.
The utility model content
The utility model purpose is exactly for a kind of mounting hole of oil sprayer depth survey cubing is provided, and is more convenient, reliable when its detects mounting hole of oil sprayer degree of depth, accuracy is high, and manufacturing cost is not high yet simultaneously.
The utility model is achieved through the following technical solutions:
Mounting hole of oil sprayer depth survey cubing is combined with positioning core axle in atomizer mounting hole intermediate gap, is sliding combined with sounding rod in the described positioning core axle; The top of described positioning core axle is installed with dial gauge, and the top of described sounding rod contacts with the side head of dial gauge.
Described dial gauge is fixed in the top of positioning core axle by the dial gauge support, and the dial gauge support is threadedly connected to the top of positioning core axle.
The utility model when carrying out depth survey with the parallel contact of cylinder head faying face with verifying bench, positioning core axle and sounding rod are inserted in the mounting hole of oil sprayer respectively, thereby top the contact with verifying bench of sounding rod will drive on the dial gauge support dial gauge action and read depth value.
The right alignment of each cylindrical of positioning core axle of the present utility model and endoporus is less than 0.02mm, and sounding rod all needs to adopt to grind with positioning core axle and standard gauge block and cooperates.
Design concept of the present utility model is a comparative measurement method, the instruments of inspection is placed on to adjust in standard cylinder cap or the standard compasses gauge block earlier to make the dial gauge pointer point to zero-bit the record standard value during measurement; To need to detect cylinder head then is placed on the verifying bench, to measure cubing again packs in the mounting hole of oil sprayer, at this moment the reading of dial gauge is the poor of measured value and standard value, this difference adds that standard value is the physical size of oil injector hole, whether meets technical requirement by judging processing dimension like this.
Concrete measuring process is as follows: earlier sounding rod and positioning core axle are carried out the standard verification with standard gauge block, adjust the dial gauge position and make that the dial gauge total indicator reading is zero-bit (just adjusts and measure fast position to standard injector mounting hole depth location); Then positioning core axle and sounding rod one covering device are inserted in the mounting hole of oil sprayer that needs the measurement cylinder head, cylinder head and verifying bench are fitted, this moment, sounding rod can drive dial gauge pointer rotation indicated depth direction difference because of the different depth of oil injector hole, this difference and the addition of standard length reading are the actual grade size of measured mounting hole of oil sprayer, and whether discriminatory analysis processing meets technical requirement successively.This kind measuring method is easy, relatively accurate, can effectively control the crudy of mounting hole of oil sprayer.
The utility model has the advantages that:
The utility model is convenient when measuring the mounting hole of oil sprayer degree of depth, reliable, accuracy is high, and manufacturing cost is not high simultaneously, have simple in structure, easy to operate, the easy advantage of processing and manufacturing, suitable medium-sized and small enterprises are used for controlling the product quality of mounting hole of oil sprayer.

Embodiment
Referring to accompanying drawing, mounting hole of oil sprayer depth survey cubing is combined with positioning core axle 1 in atomizer 5 mounting hole intermediate gaps, is sliding combined with sounding rod 2 in the positioning core axle; The top of positioning core axle is installed with dial gauge 4, and dial gauge is fixed in the top of positioning core axle by dial gauge support 3, and the dial gauge support is threadedly connected to the top of positioning core axle, and the top of sounding rod contacts with the side head of dial gauge.
Before measuring, to carry out the school odd-job work of mounting hole of oil sprayer depth survey cubing earlier with the canonical measure compasses soon, just be to use the compasses hole of standard that sounding rod 2 and dial gauge 4 are adjusted to normal place, make the pointer of dial gauge 4 point to zero-bit.
Mounting hole of oil sprayer depth survey cubing includes positioning core axle 1, and described positioning core axle 1 inserts position and the circumferencial direction that is used for the location survey bar in the mounting hole of oil sprayer; Described positioning core axle 1 top is provided with screw thread processing endoporus, reliably is connected by screw thread between dial gauge support 3 and the positioning core axle 1; Clearance fit between sounding rod 2 and the positioning core axle 1, can in positioning core axle 1, move freely, sounding rod top thimble passes positioning core axle and mounting hole of oil sprayer cylinder head faying face contacts with verifying bench, tail plane contacts with the thimble of dial gauge 4, different displacements can take place in the mounting hole of oil sprayer sounding rod 2 thimble positions to different depth, dial gauge 4 just has different reading indications, this moment, the reading of dial gauge 4 was designated as the error amount of measured hole and gauge orifice, this error amount and standard value addition was the actual processing dimension of measured mounting hole of oil sprayer.
