Abstract
The utility model relates to a novel split-type multi-cam mechanism which comprises a cam seat and cams, wherein the cam seat is in a flange shape. The novel split-type multi-cam mechanism is characterized in that grooves are formed in a side plane of the cam seat and are distributed in an annular mode with the center of the side plane of the cam seat as the center, and the number of the grooves is equal to the number of the cams. The cams are disassembly installed inside the grooves which are formed in the side plane of the cam seat, the cam working faces are in an arc shape, and the cam working face is smoothly transitioned to a cam seat plane. Due to the fact that a split-type structure is adopted between the cams and the cam seat, dismounting and installing can be achieved conveniently. When the cam working face is damaged after the cams work for a long time, a singular damaged cam can be dismounted, a new cam can be installed, and other cams and the cam seat do not need to be wholly replaced. Therefore, expenditure is saved, and the novel split-type multi-cam mechanism is economical.
Description
Technical field
The utility model relates to a kind of cam gear, relates in particular to a kind of meeting the tendency for the many cam mechanisms of New type detachable of valve block fatigue test.
Background technique
Cam can be defined as the parts with curved surface or crank slot, utilizes its swing or revolution, can make another assembly-follower that predefined motion is provided.The large section in the path of follower is limited in a chute, to obtain to-and-fro motion.cam mechanism can be realized complicated motion requirement, be widely used in various automated and semi-automatic mechanical devices, in some mechanical motion component, the friction pair of motion adopts cam mechanism often can see, he can realize the conversion of motion mode, and move relatively steady, reliably, stressed also more even in addition, he both can be converted to rotatablely moving straight line motion, also straight line motion can be converted to and rotatablely move, in the fatigue test field, particularly in valve block fatigue test field, because single part is very long working life, fatigue test is consuming time longer, cam is through friction for a long time, not only the working surface of cam can be because friction be damaged, the cams mounted one side of cam chair also can because of and driven member between friction and impaired, all need frequent replacing, and existing cam is all generally one with cam chair, must change simultaneously, only that the cam damage just need to be changed cam chair and cam simultaneously, cost is more expensive, the split of being is also arranged, but be only that cam is detachable, the replacing of cam chair needs whole cam chair is changed, cost is still very expensive, need a kind of more cost effective design.
The model utility content
The purpose of this utility model is to provide a kind of New type detachable many cam mechanisms for addressing the deficiencies of the prior art.
The purpose of this utility model is achieved through the following technical solutions; The many cam mechanisms of a kind of New type detachable, comprise cam chair, cam installation sheet and cam, the cam installation sheet is flange type, be provided with groove on one side plane of described cam installation sheet, groove is annular spread centered by the center of a side plane of cam installation sheet, the quantity of groove equates with the quantity of cam, cam is dismountable to be arranged in the groove that arranges on cam installation sheet one side plane, cam working face is curved, the plane of cam working face and cam installation sheet seamlessly transits, and the cam installation sheet is dismountable to be arranged on cam chair.
Further, on described cam, cam installation sheet and cam chair respectively correspondence be provided with screw mounting hole, cam is arranged on the cam installation sheet by screw, the cam installation sheet is arranged on cam chair by screw.
Further, the quantity of described cam is a plurality of.
Further, the quantity of described cam is 4 or 5.
Further, in described a plurality of cams, between two adjacent cams, distance equates.
The advantage of the many cam mechanisms of New type detachable that the utility model provides is: due to cam, adopt split-type structural between cam installation sheet and cam chair three person, can realize very easily dismounting and install, when cam is impaired through its working surface of working for a long time, single impaired cam can be disassembled, install new cam, when the impaired needs of cam installation sheet are changed, it can be disassembled and change, avoided changing simultaneously cam chair, saved expense, more economically.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, wherein, Fig. 1 is the structural representation of the many cam mechanisms of New type detachable of the present utility model, Fig. 2 is the cam installation sheet structural representation of the many cam mechanisms of New type detachable of the present utility model, Fig. 3 is the structural representation of the cam chair of the many cam mechanisms of New type detachable of the present utility model, and Fig. 4 is the structural representation of the cam of the many cam mechanisms of New type detachable of the present utility model.
as shown in FIG., the many cam mechanisms of a kind of New type detachable of the present utility model, comprise cam chair 3, cam installation sheet 2 and cam 1, cam installation sheet 2 is flange type, be provided with five grooves 21 on one side plane of described cam installation sheet 2, groove 21 is annular spread centered by the center of a side plane of cam installation sheet 2, the quantity of groove 21 equates with the quantity of cam 1, the quantity of described cam 1 is five, between two adjacent cams 1, distance equates, the working surface of cam 1 is curved, the plane of the working surface of cam 1 and cam installation sheet 2 seamlessly transits, be equipped with screw 22 between the adjacent notches 21 of described cam installation sheet 2, five altogether, cam chair 3 is provided with the corresponding screw 32 of screw 22 that is provided with between five adjacent notches 21 with cam installation sheet 2, cam installation sheet 2 and cam chair 3 can be fixed together by bolt, the two ends of each groove 21 on cam installation sheet 2 respectively are provided with a screw 211, the two ends of cam 1 also are provided with the screw 111 corresponding with the screw 211 that arranges of the two ends of groove 21 on cam installation sheet 2, use the bolt can be with on the dismountable groove 21 that is installed to cam installation sheet 2 of each cam 1 by screw 211 and screw 111, also be provided with assembly department 4 on cam chair 3, this assembly department 4 is used for cam chair 3 is arranged on live axle, actual conditions according to driving mechanism, if can realize being connected of cam chair 3 and driving mechanism by mounting hole is set on cam chair 3, also can replace assembly department 4 by mounting hole is set.
