Abstract
The invention discloses a sliding device. The sliding device comprises a sliding block, a main shaft and a cam, wherein the main shaft is fixedly connected with the cam; a rotating hole is formed in the sliding block, and the cam is arranged in the rotating hole; roll balls are respectively arranged on rotating hole walls on two sides of the cam and are arranged in roll ball troughs in the sliding block, centers of the two roll balls form a straight line, and the straight line is vertically crossed with the axis of the main shaft and is parallel to a motion track of the sliding block; the shape of an outer edge of a cam plane is formed by two 1/4 round sides and two symmetric arc-shaped sides, and the distances from an arbitrary straight line passing through the axial center of the main shaft on a surface where the cam plane is located to two points, crossed with the arbitrary straight line, at the outer edge of the cam plane are equal. The sliding device can stably and efficiently work and has a long service life.
Description
Technical field
The present invention relates to a kind of sliding device.
Background technique
Sliding device often can be used in production and processing machinery now, and slide block is intermittent to slide adding in tending to need sliding device man-hour.
By cam, extruding turns hole inwall and the slip of elastic device band movable slider and resets cam class sliding device majority now, and still the working state of this structure is stable not.
Spring in elastic device or extension spring have certain working life in addition.In long-time machine running process, spring or extension spring are subject to external force long term to cause wearing and tearing or elastic force to decline, so that affect the normal operation of entire machine, to product, processing brings many troubles, affect quality of product and work efficiency, and be subject to the impact of the aspect such as elastic recovery the frequency of okperation of sliding device is restricted.
In addition, cam when sliding with movable slider and slide block turn hole wall sliding friction, make cam and slide block frictional loss higher, affect the working life of sliding device.
Summary of the invention
The object of this invention is to provide sliding device.
According to an aspect of the present invention, a kind of sliding device is provided, comprise slide block, main shaft and cam, main shaft is fixedly connected with cam, slide block is provided with and turns hole, cam is located at and is turned in hole, turning of cam both sides, on hole wall, be respectively equipped with ball, ball is located in the ball grooves on slide block, in described two balls, be formed centrally straight line, the axis square crossing of this straight line and main shaft, the movement locus of described slide block and this straight line parallel, the outer rim shape of cam planes consists of two 1/4 circular edges and two symmetrical arc-shaped sides, distance between 2 that on the face of cam planes place, any straight line of spindle axis excessively and the outer rim of cam planes intersect equates.Thus, the work that sliding device can stability and high efficiency, and obviously increase the working life of sliding device.
In some embodiments, ball is spherical ball or cylindricality ball.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sliding device of an embodiment of the present invention;
Fig. 2 is the sectional view along the A-A line of the sliding device of a mode of execution in Fig. 1;
Fig. 3 is the sectional view along the A-A line of the sliding device of another mode of execution in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 has schematically shown according to the present invention the structure of sliding device.
As shown in Figure 1, sliding device, comprise slide block 1, main shaft 2 and cam 3, main shaft 2 is fixedly connected with cam 3, slide block 1 is provided with and turns hole 4, cam 3 is located at and is turned in hole 4, turning on 4 walls of hole of cam 3 both sides, be respectively equipped with ball 5, ball 5 is located in ball 5 grooves on slide block 1, in two balls, be formed centrally straight line, the axis square crossing of this straight line and main shaft 2, the movement locus of slide block 1 and this straight line parallel, the outer rim shape of cam 3 planes consists of two 1/4 circular edges and two symmetrical arc-shaped sides, distance between two points that on the face of cam planes place, any straight line in main shaft 2 axle center excessively and the outer rim of cam planes intersect equates.
During work, power plant drive main shaft 2 to rotate, main shaft 2 band moving cam 3 rotations.During cam 3 rotation, push the ball 5 of both sides always.When two 1/4 circular edges of cam 3 contact with ball 5, slide block 1 is static.When the arc-shaped side of cam 3 contacts with ball 5, slide block 1 is slided by the drive of ball 5 in the rectilinear direction at two ball 5 places, center.
Because the distance between two points that on the face of cam planes place, any straight line in main shaft 2 axle center excessively and the outer rim of cam planes intersect equates, in cam 3 rotary courses, ball 5 is adjacent to cam 3 always like this, main shaft 2 can high speed rotating and do not worry that the return speed of slide block 1 does not catch up with cam 3, produces vibration and affect sliding device stability while also worrying slide block 1 return.
In cam 3 rotary course cam 3 and 5, ball, carry out rolling friction, rolling friction frictional loss is less, the longer service life of sliding device.
As shown in Figure 2, ball 5 is spherical ball 5 in some embodiments; As shown in Figure 3, ball 5 is cylindricality ball 5 in some embodiments.
The invention provides the sliding device of the stable and long service life of a kind of efficient work.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
