Abstract
The invention discloses a strip drive chain wheel. The chain wheel comprises a round seat and chain teeth; the chain teeth are circumferentially and evenly distributed on the outer surface of the round seat, and a chain tooth correction face is arranged on each chain tooth; and the chain tooth correction faces are cutting faces formed by the manner that chain tooth outlines in the direction perpendicular to the round end face of the round seat deviate inwards by 0.05 mm to 0.1 mm to form outlines, and the outlines are cut to form the cutting faces. The chain tooth correction faces are arranged on the chain teeth of the strip drive chain wheel, and the tooth jumping shaking phenomenon during material supplying of the chain wheel is avoided.
Description
Technical field
The present invention relates to a kind of chain sprocket structure, particularly relates to a Seed packaged band driving sprocket wheel.
Background technique
The material strip driving sprocket wheel that market provides, generally on chip mounter, the intermittent motion of low speed uses, i.e. the feeding speed of less than 5/second.When the faster feed of hope, as 400/second and the motion that remains a constant speed, original material strip driving sprocket wheel just there will be jumps tooth, causes the phenomenons such as damage to material strip.
Summary of the invention
Jump the defect of tooth when the object of the invention is to overcome material strip driving sprocket wheel feed, thus adopt and the sprocket truing face is set on sprocket solves this problem.
For solve technological scheme that technical problem proposed by the invention adopts for: the sprocket wheel described in material strip driving sprocket wheel of the present invention includes round seat and sprocket, described sprocket is circularly and evenly distributed on the outer surface of circle seat, described sprocket is provided with the sprocket truing face, and the sprocket truing face is the tangent plane inwardly offseting the profile line excision formation that 0.05mm to 0.1mm is formed along the sprocket profile in direction, nose circle face perpendicular to circle seat.
The technological scheme that the present invention is further qualified is comprised:
The two ends, tooth root portion of described sprocket are equipped with avoiding hollow groove, and described avoiding hollow groove is arc groove.
Described round seat is cylindrical body, and described sprocket appearance profile is involute contour.
Described Yuan Zuo center is provided with center mounting hole.
Described round seat is provided with more than one positioning through hole.
Described plural positioning through hole is circularly and evenly distributed.
Described round seat is provided with more than one construction bolt through hole.
Described plural construction bolt through hole is circularly and evenly distributed.
By technique scheme, beneficial effect of the present invention is: the sprocket of material strip driving sprocket wheel of the present invention is provided with the sprocket truing face, prevents from jumping tooth jitter phenomenon during sprocket wheel feed.
Accompanying drawing explanation
Fig. 1 is the perspective view of material strip driving sprocket wheel of the present invention.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is described further.
With reference to Fig. 1, material strip driving sprocket wheel includes round seat 1, sprocket 2 and avoiding hollow groove 3, and sprocket 2 is circularly and evenly distributed on the outer surface of circle seat 1, and the two ends, tooth root portion of sprocket 2 are equipped with avoiding hollow groove 3, and sprocket 2 is provided with the sprocket truing face 21.In the present embodiment, circle seat 1 is cylindrical body, and material is metal, and the center of circle seat 1 is provided with a center mounting hole 4, and center mounting hole 4 is through hole.In the present embodiment, circle seat 1 is also provided with positioning through hole 5, and positioning through hole 5 is provided with two, becomes even circumferential distribution, ensures the positioning precision of sprocket wheel.During concrete enforcement, the position of peace positioning through hole 5 can be set according to actual needs.In the present embodiment, circle seat 1 is also provided with construction bolt through hole 6, construction bolt through hole 6 is provided with two, and being centrally located at of construction bolt through hole 6 center and positioning through hole 5 is circumferentially same, and two lines of centres of construction bolt through hole 6 are vertical with two lines of centres of positioning through hole 5.During concrete enforcement, the position of construction bolt through hole 6 can be set according to actual needs.In the present embodiment, on the cylndrical surface of circle seat 1, on the symmetrical line being divided into upper and lower two halves along cylndrical surface, even partition 25 equal diversion point, first point are positioned on the perpendicular bisector of two positioning through hole 5, radially respectively solid of rotation sprocket 2,25 sprockets 5 that 25 involutes make scan wheel profile are set form a circle on the cylndrical surface of circle seat 1.During concrete enforcement, quantity and the size of sprocket is set according to actual needs.Along the direction, nose circle face perpendicular to circle seat 1, sprocket profile inwardly offsets 0.05mm and forms sprocket truing face profile line, and the tangent plane formed along the excision of sprocket truing face profile line is the sprocket truing face 21.During concrete enforcement, sprocket truing face profile line can for inwardly offseting the profile line that 0.05mm to 0.1mm is formed along the sprocket profile in the direction, nose circle face perpendicular to circle seat 1.Arrange the smooth transition avoiding hollow groove 3 of arc-shaped in the sprocket truing face 21 near two ends, tooth root end, remaining convergence part is divided and is arranged to the cylndrical surface concentric with center mounting hole 4.Structure like this, defines the material strip driving sprocket wheel of SMT material strip connection machine.Wherein, the sprocket truing face 21 makes to increase point of contact between the hole wall of drive hole in the papery of sprocket and material strip or colloid base band, avoid stress concentration on a point, sprocket is better engaged with material strip in the process of transmission, prevent phenomenons such as shaking, beat, the effect of avoiding hollow groove 3 makes the foreign material such as projection, burr or broken pin on the die-cut edge of the drive hole of papery or colloid carrier band accommodate in avoiding hollow groove, there is the stop of bulging deformation or burr at anti-stopping materials strip drive hole edge in loading process driving, affect engaging of sprocket and material strip, cause the phenomenons such as shake.
Although describe in detail the specific embodiment of the present invention by reference to the accompanying drawings, should not be construed as the restriction to protection scope of the present invention.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to protection scope of the present invention.
