Abstract
The utility model relates to a device for measuring the assembly height of a diesel engine ejector. A dial indicator is arranged on a supporting seat which adopts a horizontal bridge type structure; a through hole perpendicular to the upper surface and a positioning screw hole perpendicular to the through hole are arranged on a cross beam of the supporting seat; the top rod of the dial indicator penetrates the through hole from top to bottom and is screwed from the positioning screw hole via a locking bolt for fixing the dial indicator; the lower end of the top rod of the dial indicator extends out of the cross beam, and a measuring head with the lower end surface adopting a plane surface is mounted at the lower end of the top rod; and the distance from the lower end surface of the measuring head to the lower end surface of the cross beam is smaller than the support leg height of the supporting seat. The device has the advantages of simple structure, easy operation, accurate data measurement, minor error, and great cost reduction.
Description
Technical field
The utility model relates to a kind of measurement mechanism of part assembling, is specifically related to a kind of measurement mechanism of diesel injector assembling height.
Background technology
The fuel injector overhead height that diesel engine cylinder covers is a very important size, needs accurate measurement in the process and assemble process.Because the top of fuel injector is a sphere, in case after being assemblied on the cylinder cover, just common kind of calliper can't have been adopted, so normally cooperate indirectly with standard gauge block and measure with depth gage or depth gage, its measuring method is to place standard gauge block earlier on the cylinder cover plane on fuel injector next door, the plane of orientation of depth gage with contact above the standard gauge block, regulate the gage of depth gage then downwards, measurement face contacts with fuel injector top sphere under gage, draws the reading distance on gage; Draw the desired height of fuel injector again by conversion: gauge block height-reading distance=height to be measured.Measuring method exists not enough like this, the plane of orientation that is depth gage is monolateral contact standard gauge block, be easy to small inclination, cause very big reading error like this, this just causes for measuring the different operator of skill level, perhaps same operator, because of measurement state difference, the diverse measurement result that all can draw; And the reading of measuring also needs to convert and just can obtain net result, and program is cumbersome, occurs miscount easily.To sum up, the method is used in the processing line of High-efficient Production, and production efficiency is not high, causes the stability of product quality not reach requirement easily, and the quantity of detection is few.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of measurement mechanism of diesel injector assembling height is provided, and this apparatus structure is simple, processing ease, and measurement data is accurate, error is little, can greatly improve detection efficiency.
The purpose of this utility model is achieved in that and comprises dial gauge, described dial gauge is arranged on the supporting seat, described supporting seat is a cross-bridges type structure, the crossbeam of supporting seat is provided with the through hole vertical with upper surface and perpendicular to the positioning screw hole of through hole, the push rod of dial gauge passes through hole from the top down, and screw in fixedly dial gauge from positioning screw hole with clamping screw, the push rod lower end of dial gauge is stretched out crossbeam the measuring head that the lower surface is the plane is installed, and the distance of plane separation crossbeam lower surface, measuring head lower end is less than the support foot hight of supporting seat.
Owing to adopted such scheme, dial gauge is installed on the supporting seat of a cross-bridges type structure, the crossbeam that the push rod of dial gauge passes supporting seat from the top down is provided with the through hole vertical with upper surface, and screw in fixedly dial gauge from positioning screw hole perpendicular to through hole with clamping screw, the push rod lower end of dial gauge is stretched out crossbeam the measuring head that the lower surface is the plane is installed, utilize two leg support cylinder cap surfaces of cross-bridges type supporting seat, guarantee the stability of support, can not produce operate miss.Utilize the plane of measuring head lower end to contact, because the plane of measuring head lower end is vertical with the push rod of dial gauge, so make this plane guarantee all the time high vertical with fuel injector so just can guarantee that the data that measure are accurate with the sphere of fuel injector.It is simple and convenient to adopt this measurement device diesel injector assembling highly to locate, and can increase work efficiency greatly, the error of also having avoided operating personnel's operation to bring, and it is more accurate to measure, and helps pipelining, enhances productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the synoptic diagram of supporting seat of the present utility model.
In the accompanying drawing, 1 is supporting seat, and 1a is a leg, and 1b is a crossbeam, and 2 is dial gauge, the 2a push rod, and 3 is clamping screw, and 4 is cylinder head surface, and 5 is fuel injector, and 6 is through hole, and 7 is positioning screw hole, and 8 is measuring head.
Embodiment
Referring to figs. 1 through Fig. 3, a pointer dial gauge 2 is arranged on the supporting seat 1, described supporting seat 1 is a cross-bridges type structure, the crossbeam 1b of supporting seat 1 is provided with the through hole vertical with upper surface 6 and perpendicular to the positioning screw hole 7 of through hole, the push rod 2a of dial gauge 2 passes through hole 6 from the top down, and screw in fixedly dial gauge 2 from positioning screw hole 7 with a clamping screw 3, the crossbeam 1b that supporting seat 1 is stretched out in the push rod 2a lower end of dial gauge installs the measuring head 8 that the lower surface is the plane, the plane of described measuring head 8 lower ends is vertical with the push rod 2a of dial gauge, measuring head 8 is connected by threaded engagement with the push rod 2a of dial gauge, helps after the push rod 2a of dial gauge 2 passes the crossbeam 1b of supporting seat 1 installing and measuring 8.After measuring head 8 is installed on the push rod 2a, the distance of plane separation crossbeam 1b lower surface, measuring head 8 lower end is less than the height of the leg 1a of supporting seat 1, after making supporting seat 1 be supported on the cylinder head surface 4, has the locational space of fuel injector 5 between the measuring head 8 lower end plane separation cylinder head surface 4.
When using this measurement device diesel injector assembling height, calibrate dial gauge 2 earlier, then this measurement mechanism is moved to cylinder head surface to be measured, make two legs of supporting seat be close to cylinder head surface, make that transverse plane contacts with the sphere top of fuel injector under the measuring head of installing on the push rod of dial gauge, the pointer of dial gauge turns to a certain position, be the assembling height of fuel injector, as conforming to design height, then qualified for assembling, as not conforming to, then being defective.Simple, convenient, quick, can greatly improve detection efficiency.
