Abstract

The utility model discloses a ball-shaped cam drive mechanism for the textile industry, the printing industry, the movie industry, etc., which is composed of a ball-shaped cam formed by a spherosome whose surface is provided with an annular groove, a driving shaft connected with the ball-shaped cam, and a driven mechanism driven by the ball-shaped cam. The ball-shaped cam and a shaft sleeve are supported on a machine frame, and the driving shaft is connected with the ball-shaped cam via a key. The driven mechanism is composed of rollers, support frames, bearings, guide rods, and a swing cylinder. The roller is arranged on the support frame via a core shaft and moves along the annular groove of the surface of the ball-shaped cam, and the support frame is connected with the guide rod via the bearing. The guide rod is arranged on the machine frame via the swing cylinder, and both sides of the annular groove are provided with locking strips.

Description

Spherical cam drive structure
The utility model relates to a kind of cam drive machinery, be specifically a kind ofly apply to weave, the spherical cam drive structure of industry such as printing, film.
Traditional cam has disk cam, wedge cam, cylindrical cam, conical cam.As long as design certain cam profile curve, just can make follower lever obtain the predetermined arbitrarily characteristics of motion, can only be unique but above-mentioned cam makes the characteristics of motion of follower lever.
The purpose of this utility model is to provide a kind of spherical cam drive structure that can make follower lever obtain the multiple characteristics of motion.
To achieve these goals, the utility model adopts following technological scheme: a kind of spherical cam drive structure, it is characterized in that: it is by the formed spherical cam of the spherosome of driving circular groove on the surface, one driving shaft and that connects with this spherical cam is formed by the follower of this spherical cam drive, this spherical cam through axle and sleeve supporting on frame, this driving shaft and this spherical cam key connecting, this follower is by roller, support, bearing, guide rod and pendulum tube are formed, this roller is installed on this support through mandrel, and move along the circular groove on the spherical cam face, this support connects this guide rod through this bearing, this guide rod is installed on this frame through this pendulum tube, and the both sides of spherical cam circular groove are provided with sealed.
Compared with the prior art the utility model has conspicuous advantage: offer circular groove on the spherosome surface, to form spherical cam, the characteristics of utilizing the spherosome diameter to equate everywhere, as long as change driving shaft and spherical cam coupled position, just can make follower lever obtain the multiple characteristics of motion, thereby reach the purpose that a cam can replace a plurality of cams, increase economic efficiency.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is the kinematic sketch of spherical cam drive before preferred embodiment running shaft change of the utility model;
Fig. 3 is the kinematic sketch of the spherical cam drive in the utility model preferred embodiment running shaft change back;
Fig. 4 is the triangle relation between 3 of A, B in spherical cam drive of preferred embodiment of the utility model, the O.
At first see also shown in Figure 1, the utility model is by the formed spherical cam 10 of the spherosome of driving circular groove 11 on the surface, one driving shaft 20 and that connects with this spherical cam is formed by the follower 30 of this spherical cam drive, this spherical cam is through axle 13,20 with axle sleeve 12,14 are bearing on the frame 40, this driving shaft and this spherical cam key connecting, this follower is by roller 31, support 32, bearing 33, guide rod 34 and pendulum tube 35 are formed, this roller is installed on this support through mandrel 36, and move along the circular groove on the spherical cam face, this support connects this guide rod through this bearing, this guide rod is installed on this frame through this pendulum tube, and the both sides of spherical cam circular groove are provided with sealed 15.The utility model input motion form is the at the uniform velocity continuous rotation of spherical cam, and the output movement form is the reciprocal swing of driven guide rod.Applicable to fields such as weaving, printing, motion picture productions.
In order making the utility model there is a clearer understanding, below lifts a utilization example.See also Fig. 2, Fig. 3 and shown in Figure 4, among Fig. 2, spherical cam diameter D=150mm, the guide rod fixed center is A0=172mm to spherical cam center distance, the inclined angle alpha of circular groove 1=30 °, the full swing angle φ of guide rod 1=144 °.If make the full swing angle φ of guide rod 2In the time of=30 °, the running shaft of spherical cam should be suitable wherein.Now be analyzed as follows:
In Δ AOB, get by sine:
AO/SinB=BO/SinA,
Be (15 °+α of 172/Sin 2)=75/Sin15 °,
Sin(15°+α 2)=172×Sin15°/75,
Try to achieve as calculated:
α 2=21°25′,
Δα=α 12
=30°-21°25′
=8°35′
Be the rotary main shaft of spherical cam should turn clockwise in the great circle position of Fig. 28 ° 35 ' to C 1, C 2On, as shown in Figure 3.
