Abstract
The utility model relates to an adjustable cam mechanism with end teeth engaged, which is characterized in that an adjustable cam component with end teeth engaged is arranged on a camshaft, and is composed of a fixed disk, a left cam disk and a right cam disk; end surface teeth are arranged on the mutual abutting end surfaces of the fixed disk, the left cam disk and the right cam disk; the fixed disk, the left cam disk and the right cam disk are engaged and connected by the end surface teeth; an integral convex key is arranged on the shaft hole of the fixed disk, and is matched with a key groove on the camshaft. The utility model has the advantages that the utility model can carry out large and micro adjustment, and has high control precision, convenient, fast and accurate operation for adjustment, and convenient assembly and maintenance.
Description
The utility model relates to the composition mechanism of low-voltage controling appliance equipment, and specifically a kind of end tooth meshes adjustable type cam mechanism.
Cam mechanism is the core institution in a lot of low-voltage controling appliance equipment, mainly is made up of camshaft, cam pack, keeper etc.Cam mechanism has adjustable and non-adjustable, adjustablely is meant that the cam pack of direct control circuit break-make is adjustable.The adjustable type cam assembly mainly is made up of cam disc and cam bit at present, and cam disc upper edge circumference is shaped on connecting hole, and cam bit is fastened on the connecting hole with screw, unclamp trip bolt during adjustment, cam bit is moved on to desired position on the cam disc, be fastenedly connected again again, reach the purpose of adjustment.This structure weak point is:
1, limit by the connecting hole position, adjustment and trace adjustment are all not ideal enough significantly, and precision is not high, and after the long-time use, the easy play of cam bit can't guarantee control precision.
To debug repeatedly when 2, adjusting, take a lot of work, time-consuming, be interrupted and produce.
3, assembling, inconvenient maintenance.
The purpose of this utility model provides a kind of easy to adjust, the adjustable type cam of end tooth engagement fast and accurately mechanism.
The purpose of this utility model is to realize like this; It comprises camshaft, keeper, it is characterized in that: end tooth engagement adjustable type cam assembly is housed on camshaft, and it is made up of fixed disk, left cam disc, right cam disc, is shaped on the end face tooth on the end face that the three is docked mutually, with the connection that is meshed of end face tooth; Be shaped on the protruding key of disjunctor on the axis hole of fixed disk, match with keyway on the camshaft.
Above-mentioned cam mechanism is characterized in that being fitted with elastic component on camshaft one end, is provided with spring between the end tooth engagement adjustable type cam assembly.
Above-mentioned cam mechanism is characterized in that being shaped on angle graticule and angle value on the cam disc value of the reading circumference of the left and right sides, is shaped on the fixed disk excircle and the corresponding position line of angle graticule.
The utility model has the advantages that:
1, is shaped on enough end face teeth on the cam disc of the left and right sides, thereby can adjusts significantly, can carry out trace adjustment again, can in 360 ° of scopes of corner, close action, control precision height in adjustment pass in optional position.
2, being provided with spring between the cam pack, is the end tooth Elastic Meshing, therefore, can control needs are directly adjusted left and right sides cam disc with hand relative position according to circuit, simple, convenient, quick, accurate, shortens the adjustment time more than 90%.
3, assembling is easy to maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Fig. 2 is the cam pack end tooth structural representation that is connected with a joggle.
Shown in Fig. 1-2, be equipped with keeper 2, end tooth engagement adjustable cam assembly 3 on the camshaft 1 of cam mechanism successively, play basket for holding earth 7, elastic component 8, spring 7 is arranged on the position of supporting and stablizing each cam pack 3 between the cam pack 3.Cam pack 3 is made up of fixed disk 4, left cam disc 5, right cam disc 6, is shaped on end face tooth 11 on the end face that the three connects, with end face tooth 11 connection that is meshed; The axis hole of fixed disk 4 is shaped on the protruding chain 10 of disjunctor, matches with key way 9 on the camshaft 1.Be shaped on angle graticule 12, angle value 13 on the value of the reading circumference of left and right sides cam disc 5,6, be shaped on the excircle of fixed disk 4 and angle graticule 12 corresponding position lines 14.Directly with hand fixed disk 4, left and right sides cam disc 5,6 threes are thrown off during adjustment, forward left and right sides cam disc 5,6 to desired location then, the back three that looses one's grip reaches the adjustment purpose again with end face tooth 11 connection that is meshed.
