Embodiment
The invention discloses the online appliance special for detecting of a kind of camshaft, to improve the detection efficiency of camshaft.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also Fig. 1 and Fig. 2, the main TV structure synoptic diagram of the online appliance special for detecting of camshaft that Fig. 1 provides for the embodiment of the invention; The plan structure synoptic diagram of the online appliance special for detecting of camshaft that Fig. 2 provides for the embodiment of the invention.
The online appliance special for detecting of camshaft provided by the invention comprises camshaft locating device and measurement mechanism.Wherein, the camshaft locating device is used for the locus of positioning cam axle 10, guarantee that each camshaft 10 is assembled on the camshaft locating device after, its locus is all identical, thereby confirms the accuracy that each camshaft 10 is measured.Camshaft 10 at first should be positioned at this camshaft 10 on this camshaft locating device before measurement, to confirm its locus.Measurement mechanism is arranged on the frame (i.e. a fixed installing component), and it has two relatively measurers 11 at least, and the test lead of comparison measurer 11 is corresponding with the position to be tested of camshaft 10.After camshaft 10 is mounted on the camshaft locating device; Relatively measurer 11 is convenient to confirm with the position of camshaft 10; Therefore each camshaft 10 is all identical with the relative position that compares measurer 11; Measure the vertical relatively of camshafts 10 through comparing measurer 11, can draw the error relative value of camshaft to be measured and satisfactory camshaft, can judge then whether camshaft to be measured meets technical requirement.It will be understood by those skilled in the art that comparison measurer 11 can only measure relative value, can not measure absolute figure, be mainly used in and measure shape and site error, for example measurer such as dial indicator.
The present invention is after being positioned at camshaft to be measured on the camshaft locating device, and then the locus of camshaft to be measured is just definite.Before the detection, prepare a sample (it is qualified that angle requires, and be in standard value) earlier; Sample is positioned on the camshaft locating device, and relatively measurer 11 holds out against on the surface of camshaft position to be measured, and the reading that will compare measurer then is to zero; Take off sample; The product that will detect in the same way clamping on the camshaft locating device, relatively measurer hold out against with sample same position place, the reading contrast can judge fast whether this product qualified.
The camshaft locating device can specifically comprise locating rack, first top 7, second top 1 and register pin 4.Wherein, Locating rack has first riser 6 and second riser 2 at least; Spacing between first riser 6 and second riser 2 is greater than the length of camshaft 10, and to guarantee that camshaft 10 can be positioned between the two, first riser 6 and second riser 2 are used for installing respectively first top 7 and second top 1.First top 7 is arranged on first riser 6, and second top 1 is arranged on second riser 2, and first top 7 and second top 1 has at least one to be rolling center.First top 7 and second top 1 is used for withstanding respectively the center pit of the camshaft left and right sides, plays the effect of centering, and in first top 7 and second top 1 at least one is designed to rolling center, and purpose is to make things convenient for the installing and locating of camshaft 10.In the present embodiment one of them top be fixed sturcture, another is a bascule, during installation, only needs regulate rolling center getting final product.Register pin 4 links to each other with first top 7 or second top 1; Mounting hole on the flange of itself and camshaft is suitable; Promptly after camshaft 10 is mounted on first top 7 and second top 1; Should register pin 4 be inserted in the corresponding mounting hole on the ring flange, with the rotation of restriction camshaft 10, and after the inserting of the corresponding mounting hole can also guarantee each camshaft 10 installations on register pin 4 and the ring flange; Each camshaft 10 is identical with the correspondence position that compares measurer 11, thereby guarantees to compare the site error that measurer 11 is measured same position on the camshafts 10.
In a specific embodiment of the present invention, register pin 4 can link to each other with first top 7 through Connection Block 5, and Connection Block 5 is set in first top 7 near on second top 1 the end, and register pin 4 is arranged on the Connection Block 5.Connection Block 5 can pass through the pretension screw lock after being sheathed on first top 7, prevent that Connection Block 5 from moving axially.Generally should with Connection Block 5 be fixed on fixed top on, therefore in the present embodiment, first top 7 is stationary center, second top 1 is rolling center.Promptly second top 1 be slidingly fitted in the mounting hole of second riser 2, and through lock-screw 9 pretensions, during dismounting camshaft 10; Can at first lock-screw 9 be unscrewed, slide backward second top 1 then, make two distances between top greater than the length of camshaft 10; Just can camshaft 10 be taken out, and then assemble next camshaft, two top camshaft 10 is held out against after; Lock-screw 9 is screwed, prevented that second top 1 moves.Second the pre-tightening apparatus on top can be taked modes such as spring, air pressure or hydraulic pressure, and the present invention does not limit.
Locating rack can comprise that base plate 3, the first risers 6 and second riser 2 are separately positioned on the two ends of base plate 3, and measurement mechanism is arranged on the base plate 3.Measurement mechanism can specifically comprise mount pad 8 and compare measurer 11 that wherein, mount pad 8 can be two; And be separately positioned on the both sides of base plate 3, corresponding, relatively measurer 11 also is two; And be separately positioned on two mount pads 8, two comparison measurers 11 are preferably and are oppositely arranged.Two relatively measurer 11 can judging the whether qualified requirement of camshaft fully, but it will be appreciated by persons skilled in the art that the quantity of comparison measurer 11 is many more, its measurement is accurate more.Because the present invention only needs judge fast that this camshaft 10 is whether qualified or satisfy technical requirement, therefore two comparison measurers 11 is set can reach criterion fully.
Each embodiment adopts the mode of going forward one by one to describe in this instructions, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
