Abstract
The utility model discloses a cam capable of randomly adjusting eccentricity, comprising an internal sleeve and an outer wheel. The internal sleeve is assembled in the outer wheel. The internal sleeve is connected with a driving shaft through a driving shaft connecting hole. The outer wheel fastening grooves on the outer wall of the two annular walls of the internal sleeve are connected with the outer wheel and limit the outer wheel to move axially. The two threaded holes on the outer wheel are used to tightly fasten the outer wheel onto the internal sleeve. When the eccentricity is adjusted, the adjustment of the eccentricity can be completed by lossening the screws on the threaded holes, adjusting the outer wheel to the required position, and fastening the screws again. The utility model has the advantage of easy adjustment and is suitable for the situation that the eccentricity can be adjusted frequently. In addition, the utility model can be used in the mechanical movement which can realize the up and down movement, swing movement, etc., in particular to the situation that the eccentricity can be randomly adjusted.
Description
Technical field
The utility model relates to a kind of cam, the particularly a kind of cam that can regulate offset arbitrarily.
Background technique
Existing offset regulation technology comprises following two kinds of methods: a kind of method is the mode that cam is changed in employing, but needs several cams of processing like this, and the method making, keeping and administration cost are higher, and the workload of changing is big, and it is also very inconvenient to operate; Also having a kind of method is to adopt circular offset formula cam, one of the most frequently used cam that circular offset formula cam is a kind of simplicity of design, be easy to process.The adjusting of the offset of this cam can adopt the mode of making several eccentric openings on cam to finish, but this method can cause certain destruction to workpiece, and the conciliation amount of this kind adjusting is very limited.But the method that these two kinds conventional cam offsets are regulated is the adjusting of limited several offsets of quantity performed only, can't realize any adjusting of offset.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that above-mentioned cam adjustment inconvenience maybe need be changed, provide a kind of offset within the specific limits arbitrarily flexibility regulate and cam easy to adjust.
For achieving the above object, the technical solution adopted in the utility model is: cover and foreign steamer two-part in comprising, interior cover is assemblied in the foreign steamer, it is characterized in that, cover comprises the live axle attachment hole in said, inner sleeve shape wall body is provided with live axle clamp screw pit, and inner sleeve shape wall body outer wall is provided with the foreign steamer binding groove; Cover attachment hole in foreign steamer comprises simultaneously, foreign steamer ring-type wall body is provided with tapped hole, and the outer wall of foreign steamer ring-type wall body is provided with camming surface.
The utility model improves by said structure, because only two screw adjusted foreign steamer desired locations need unclamping on the tapped hole just can realize any adjusting of cam offset in 0～e scope, method is feasible, is easy to regulate, and is particularly suitable for being applied in offset and needs the often occasion of adjusting.This cam mechanism can be used on the occasion that mechanical motion, especially offsets such as realization moves up and down, oscillating motion can be regulated at any time.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional drawing of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
Embodiment
As shown in Figure 1, 2, cover 2 and foreign steamer 3 two-part in the utility model comprises, interior cover 2 is connected with live axle by live axle attachment hole 1 and keys on the interior cover 2, by the screw in the live axle clamp screw pit on the cover 2 in being assemblied in 4 interior cover 2 is fixed on the live axle, the integral installation that forms fits in interior cover 2 attachment holes 7 of foreign steamer 3, and camming surface 8 is the final working surface of this cam.Foreign steamer binding groove 5 on the external wall of interior cover 2 annular wall is used for connecting foreign steamer 3 and can limits its axial float, and two tapped holes 6 of configuration on the foreign steamer 3 are tightened to foreign steamer 3 on the interior cover 2 by the screws that are assemblied in the tapped hole 6.
The live axle attachment hole 1 of interior cover 2 and the interior cover attachment hole 7 of foreign steamer 3 all have the offset of e/2 with live axle.Rigging position on interior cover 2 and the foreign steamer 3 is as shown in the figure the time, and live axle attachment hole 1 overlaps with the center of foreign steamer 3, and this moment, the offset of this cam was 0, i.e. the offset minimum; In cover 2 and the rigging position of foreign steamer 3 when the centre distance of live axle attachment hole 1 and foreign steamer 3 is e/2+e/2=e then the offset of this cam be e, i.e. offset maximum; Interior cover 2 and foreign steamer 3 are according to the needs of actual conditions, and when being assemblied in the arbitrary position between the two, the offset of this cam is respective value place between 0～e.
When this cam will be regulated offset, only need unclamp two screws in the tapped hole 6, regulate foreign steamer 3 to desired location, again that screw is fastening, can finish the adjusting of offset.
Claims (3)
1, a kind of cam that can regulate offset arbitrarily is characterized in that comprising interior cover (2) and foreign steamer (3) two-part, and interior cover (2) is assemblied in the foreign steamer (3).
2, according to claims 1 described cam that can regulate offset arbitrarily, it is characterized in that, cover (2) comprises live axle attachment hole (1) in said, interior cover (2) ring-type wall body is provided with live axle clamp screw pit (4), and interior cover (2) ring-type outer wall outer wall is provided with foreign steamer binding groove (5).
3, according to claims 1 described cam that can regulate offset arbitrarily, it is characterized in that, cover attachment hole (7) in said foreign steamer (3) comprises, foreign steamer (3) ring-type wall body is provided with tapped hole (6), and the outer wall of foreign steamer (3) ring-type wall body is provided with camming surface (8).
