Abstract
The utility model relates to a wall thickness and depth dimension combined measuring device; the technical scheme of the measuring device comprises a pedestal, a support, a fastening screw and measuring rods; the support is vertically fixed on the pedestal and provided with a fixing hole; the fastening screw and the support are in thread connection; the front end of the fastening screw can probe into the fixing hole, and the rear end of the measuring rod is placed in the fixing hole; the fastening screw fixes the measuring rod on the support; the front end of the measuring rod is marked with a through end line and a stop end line of an inner hole depth dimension of a tested piece. The wall thickness and depth dimension combined measuring device can realize simultaneous measurement of small size and high precision oil injection rod wall thickness dimension and inner hole depth dimension, is very suitable for small size, high precision and mass production products, can save large scale production cost, improves work efficiency, and ensures measuring quality and precision.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly relates to a kind of wall thickness and depth dimensions combination metering device.
Background technology
Aeromotor is obtained power by firing chamber, and for obtaining best oil gas mixing ratio, fuel manifold structure is updated, and Fuel Injector Bar is tending towards the design of small size and most amounts, as shown in Figure 2.
Fuel Injector Bar wall thickness dimension is measured, and prior art adopts Non-Destructive Testing (ultrasonic thickness measurement, eddy current thickness measuring etc.) and wall thickness calipers more.Lossless detection method cost of equipment drops into high, simultaneously large for the large product measuring error of curvature, to operator Personal Skills level, requires high; Wall thickness calipers is hand-held simple measurement tool, because its clamping device is more complicated, measuring basis position cannot reach in Fuel Injector Bar endoporus, measurement accessibility is poor, and based on above reason, the wall thickness dimension that these two kinds of measuring methods cannot effectively solve small size, precision part detects.
Endoporus depth dimensions is measured, existing method adopts pit gauge or with the vernier caliper of depth measurement device more, when the surveyors' staff portion size of these two kinds of measurers is greater than tested part diameter of bore size, cannot realize measurement function, existing aeromotor Fuel Injector Bar diameter of bore is less than 3mm conventionally, and pit gauge and vernier caliper cannot meet measurement requirement.
When particularly this type of part in enormous quantities need to be measured, measuring accuracy and quality cannot guarantee, efficiency is low, can not meet production requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of wall thickness and depth dimensions combination metering device, when can realize small size, high precision Fuel Injector Bar wall thickness dimension and endoporus depth dimensions, measures.
The technical solution of the utility model is: a kind of wall thickness and depth dimensions combination metering device, comprise base, support, lock-screw and sounding rod, described support vertical is fixedly installed on described base, described support is provided with fixed orifice, described lock-screw and described support are threaded connection, described lock-screw front end can be visited in described fixed orifice, described sounding rod rear end is placed in described fixed orifice, described lock-screw is fixed on described sounding rod on described support, end groove and the not-go-end groove excessively of inner bore of part depth dimensions surveyed in the marking of described sounding rod front end.
Described wall thickness and depth dimensions combination metering device, preferred version is, and described sounding rod specification is different, and quantity is a plurality of; A plurality of jacks are set, for laying described sounding rod on described base.
Principle of work of the present utility model and course of action are as follows:
One, according to Fuel Injector Bar size, select sounding rod, this measurement mechanism detects in order to meet the Fuel Injector Bar of different size, and standby multiple sounding rod, can select according to product needed.
Two, according to Fuel Injector Bar size, select meter, meter is installed on dial framework; Measurement mechanism and dial framework are placed in identical platform simultaneously and carry out meter calibration, and sounding rod is locked on support with lock-screw, and on sounding rod, calibration measurement list index makes zero.
Three, Fuel Injector Bar is enclosed within on sounding rod, and is inserted into the end, see and look into the position that Fuel Injector Bar end face was positioned at end groove and not-go-end groove, it is qualified between mistake end groove and not-go-end groove, to be, otherwise product is overproof.
Four, with meter, detect Fuel Injector Bar outer wall and see total indicator reading, meter reading and wall thickness dimension tolerance compare, qualified in margin tolerance, otherwise product is overproof.
The beneficial effects of the utility model: measure when this measurement mechanism can be realized small size, high precision Fuel Injector Bar wall thickness dimension and endoporus depth dimensions, be highly suitable for small size, high precision, large batch of product, can save a large amount of production costs, increase work efficiency, guarantee measurement quality and precision.
