Description
Technical field
The present invention relates to the cutting machine technical field, specifically is a kind of plastic pipe multi-claw clamping mechanism that is used for cutting machine.
Background technology
Planet saw blade cutting machine or blade cut-off machine great majority adopt Hough seat clamping devices before and after the servo-actuated case in the existing plastic tube industry, and its structure generally comprises up and down the Hough seat, clamps Hough, a plurality of cylinder, guide pillar, guide pillar seat etc. up and down.Clamp Hough up and down and be separately fixed at up and down on the Hough seat, a plurality of cylinders are installed in respectively up and down on the Hough seat, clamp Hough up and down and clamp plastic pipe under the promotion of cylinder, and guide pillar and guide pillar seat play the effect of a guiding.There is following shortcoming in above prior art: owing to clamp the internal diameter size of Hough up and down is unique, so clamping Hough up and down need change at any time according to the external diameter of extrusion plastic tubing, cause time-consumingly, and the plastic pipe of each specification need be equipped with a cover and clamps Hough, cost height.During in addition owing to clamping Hough clamping plastic pipe, be whole outside cylinder side face contact,, generally adopt the lower aluminium of hardness, so just increased manufacturing cost in order to reduce outer wall damage to plastic pipe.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of can be in the certain diameter scope plastic pipe of clamping various outer diameter and saving of work and time, make the plastic pipe multi-claw clamping mechanism that is used for cutting machine of low cost of manufacture.
Technical scheme of the present invention is, a kind of plastic pipe multi-claw clamping mechanism that is used for cutting machine with following structure is provided, and comprises wallboard and cylinder, and an end of described cylinder is hinged on the wallboard; Be characterized in: it also comprises connecting plate, at least three pivoted arms and with pivoted arm bolster one to one, linkage, last lower reinforcing plate, described bolster evenly distributes along the circumference of wallboard, described pivoted arm comprises swing arm and swing arm, the tie point of described swing arm and swing arm is hinged on the bolster, the described lower reinforcing plate of going up is fixedlyed connected with swing arm, described linkage is located at adjacent two respectively and goes up between the lower reinforcing plates and hinged with the two ends of last lower reinforcing plate, distance between two pin joints of each linkage all equates, polygon of the end to end composition of described linkage and last lower reinforcing plate, one end of described connecting plate and the piston rod of cylinder are hinged, the other end of described connecting plate is fixedlyed connected with a last lower reinforcing plate in the described polygon, and described linkage comprises connecting rod, extension bar; The two ends of described connecting rod are equipped with screw rod, the screw rod of connecting rod one end is a left-hand thread, the screw rod of the connecting rod other end is a right-hand thread, one end and the last lower reinforcing plate of described extension bar are hinged, the other end of described extension bar is connected with the screw flight of connecting rod, and the screw rod place, two ends of described connecting rod is equipped with the locking nut I.
After adopting above structure, the present invention compared with prior art, have following remarkable advantage and beneficial effect: because at least three pivoted arms that are used for the plastic pipe multi-claw clamping mechanism of cutting machine of the present invention rely on its corresponding linkage hinged, form the closed polygon of a rule, and it is hinged with the bolster that is evenly distributed on the wallboard respectively, the pin joint of adjacent like this two pivoted arms and bolster and and two pivoted arms between the pin joint of linkage form a parallelogram, pivoted arm is followed parallelogram law all the time when swing, at least three pivoted arms are rotated to same direction when swing, distance between two pin joints of each linkage all equates, to realize the clamping synchronously of all pivoted arms or to open synchronously, guarantee that the swing arm of all pivoted arms all with by the outer wall of the plastic pipe of clamping is all fitted.In addition because the piston rod of described connecting plate one end and cylinder is hinged, its other end is fixedlyed connected with lower reinforcing plate on wherein one group, provides power to promote one of them pivoted arm by connecting plate by cylinder, drives remaining pivoted arm again and links together.Since the swing arm of each pivoted arm of the plastic pipe multi-claw clamping mechanism that is used for cutting machine of the present invention with contacted by the exterior line of the plastic pipe of clamping, so only need be in the hunting range of swing arm just can the clamping various outer diameter plastic pipe, saving of work and time, cost are low; And because line contact is difficult for by the damage of the outer wall of the plastic pipe of clamping, improve a little in swing arm place of pivoted arm, pivoted arm also can adopt common cast steel or group welding piece, not necessarily will adopt aluminium, has so just reduced manufacturing cost.Can regulate two distances between the pivoted arm by connecting rod and extension bar like this; and screw rod one end that the two ends of described connecting rod are provided with is a left-hand thread; the other end is a right-hand thread; when pivot link; can make pivoted arm motion together in the other direction, promptly simultaneously to connecting rod draw close or simultaneously to connecting rod away from, then with the locking of locking nut I; guarantee that distance equates between each pivoted arm, reach best actual clamping effect.
As improvement, also be provided with joint between the piston rod of described connecting plate and cylinder, one end of described joint is connected with the piston rod thread of cylinder, and the other end and the connecting plate of described joint are hinged, also is provided with the locking nut II between the piston rod of described joint and cylinder.Adjust distance between piston rod and the connecting plate by being spirally connected of joint and piston rod,, also just finely tune the hunting range of pivoted arm, can adjust the maximum or minimum clamping external diameter of apparatus of the present invention thus then with the locking of locking nut II.
