Abstract
The invention discloses a cam clamping mechanism which comprises a cam and a handle. The cam clamping mechanism is characterized in that the mechanism further comprises rocker arms, rotating shafts and adjusting screws, the bottom of the cam is provided with a connection column, the side face of the connection column is transversely connected with the handle, the three rocker arms making contact with the cam are distributed on the edge of the cam and are fixed through the rotating shafts in a rotating mode, and the rear ends of all the rocker arms are provided with the adjusting screws for adjusting the tensile force of the rocker arms. The cam clamping mechanism solves the problems that in the prior art, a clamping mechanism is complex in structure, multiple components are needed to drive multiple rocker arms to conduct clamping at the same, the clamping mechanism is inconvenient to use, meanwhile the tensile force of all the rocker arms cannot be adjusted, the clamping force cannot be changed, the clamping effect is poor, and the clamping requirement of various parts cannot be met and is simple in structure, convenient to drive and adjustable in clamping force.
Description
Technical field
The present invention relates to a kind of clamp system, particularly relate to a kind of cam clamping mechanism.
Background technology
Current clamp system complex structure, can not utilize parts to drive multiple rocking arm to clamp simultaneously, use inconvenience, and the tensile force of each rocking arm cannot regulate simultaneously, and clamping dynamics can not change, and clamping effect is poor, cannot meet various part clamping needs.
Summary of the invention
In order to solve clamp system complex structure in prior art, parts can not be utilized to drive multiple rocking arm to clamp simultaneously, use inconvenience, the tensile force of each rocking arm cannot regulate simultaneously, and clamping dynamics can not change, and clamping effect is poor, the problem of various part clamping needs cannot be met, the invention provides a kind of structure simple, it is convenient to drive, the cam clamping mechanism that clamping dynamics is adjustable.
In order to solve the problem, the technical solution used in the present invention is:
A kind of cam clamping mechanism, comprise cam and handle, it is characterized in that: also comprise rocking arm, rotating shaft and adjusting screw(rod), joint pin is provided with bottom cam, described joint pin side is horizontally connected with one handle, cam edge be distributed with three with the rocking arm of cam contact, described rocking arm is fixed in a rotative pattern by rotating shaft, and each rocking arm rear end is provided with the adjusting screw(rod) for adjusting rock arm tensile force.
Aforesaid a kind of cam clamping mechanism, is characterized in that: described handle and cam are parallel to each other.
Aforesaid a kind of cam clamping mechanism, is characterized in that: described rocking arm top extends internally formation snap fit.
Aforesaid a kind of cam clamping mechanism, is characterized in that: being uniformly distributed three in cam edge has the rocking arm contacted with cam, and the distance between described adjacent two rocking arms is equal.
Aforesaid a kind of cam clamping mechanism, is characterized in that: described rotating shaft is through in the middle part of rocking arm.
Aforesaid a kind of cam clamping mechanism, is characterized in that: described cam adopts metal material to make.
The beneficial effect that the present invention reaches: cam clamping mechanism of the present invention, joint pin is provided with bottom cam, described joint pin side is horizontally connected with one handle, cam edge be distributed with three with the rocking arm of cam contact, turning handle can make cam rotate, and actuated by cams three rocking arms rotate around the axis and to be clamped by part.The present invention is provided with adjusting screw(rod) in rocking arm rear end, and for regulating the size of clamping force, can regulate according to the difference of holding parts like this, use convenient, clamping effect is better.
