Abstract
The invention relates to a limit conversion mechanism of a five-shaft steel tube intersection line cutter. A parallelogram connecting rod mechanism comprising a transverse upper connecting plate, a transverse lower connecting plate, a vertical front swinging arm and a vertical rear swinging arm is connected to a base of a front connecting rod swinging component and a rear connecting rod swinging component of a cutting head through a pivot, a motor is fixedly arranged on the base, an output shaft of the base is connected with the rear swinging arm through a transmission shaft, a gear wheel is fixed on the tail end of the transmission shaft, a guide shaft is arranged at one side of a rack meshed with the gear wheel, and an origin induction sheet is arranged at the other side of the rack; and the guide shaft horizontally slides in a guide groove of a lateral plate of the base, an origin limit switch is arranged on the lateral plate, and a left limit switch and a right limit switch are arranged at two ends of the guide groove. In the invention, the limit conversion mechanism is additionally arranged relative to the front connecting rod swinging component and the rear connecting rod swinging component of the cutting head and used for carrying out precise swinging limit control on the connecting rod mechanism; and the limit conversion mechanism has the advantages of flexible installation, convenient control, convenient installation and maintenance, good reliability and high precision.
Description
Technical field
The present invention relates to steel pipe process equipment field, especially five-axis steel pipe intersecting line cutting machine.
Background technology
Five-axis steel pipe intersecting line cutting machine utilizes cutting head that the pipe material is cut, and cutting head front-rear linkage tilting member can make cutting cutting torch and pipe material shape have a certain degree, and is used for processing bevel cut.Present cutting head front-rear linkage tilting member structure is referring to Fig. 1, Fig. 2, pedestal 6 is installed in cutting head and swings on the swing arm of parts, on pedestal 6 by pivotally connected horizontal upper junction plate 2, lower connecting plate 3 and vertical front swing arm 4, the parallelogram linkage that rear-swing arm 5 is constituted, front end at upper junction plate 2, lower connecting plate 3 is installed grip slipper, in order to clamping flame or plasma cutting gun 1; Motor 7 is installed on the pedestal 6, by power transmission shaft 8 and rear-swing arm 5 engagements.During real work, the output of motor 7 is converted into the rotation of rear-swing arm 5 by power transmission shaft 8, thereby drives the distortion of whole parallelogram linkage, and the cutting gun 1 that makes front end that the grip slipper clamping is installed is a center swing certain angle with the torch head.In prior art, the origin switch of linkage swing mechanism and limit switch all are mounted on the track of connecting rod swing, and installation adjusting difficulty is bigger; And because limited space is not easy to install case, the flue dust that cutting produces is more, so reliability is not fine, often will clear up flue dust; The electric wire of switch is touched by swing mechanism easily, influences device security.
Summary of the invention
The applicant is at above-mentioned existing steel tube cutting machine linkage swing mechanism operating maintenance complexity, and defectives such as poor reliability provide limit conversion mechanism of five-shaft steel tube intersection line cutter a kind of rational in infrastructure, easy to operate, can carry out spacing control safely and efficiently.
The technical solution adopted in the present invention is as follows:
A kind of limit conversion mechanism of five-shaft steel tube intersection line cutter, pass through pivotally connected horizontal upper junction plate on the pedestal of cutting head front-rear linkage tilting member, lower connecting plate and vertical front swing arm, the parallelogram linkage that rear-swing arm constituted, at described pedestal fixed installation motor, its output shaft is connected with rear-swing arm by power transmission shaft, be fixed with gear at described transmission the tip of the axis, with tooth bar one side of gears engaged the axis of guide is installed, opposite side is equipped with the initial point sensing chip, axis of guide horizontal slip in the gathering sill of base side boards, the initial point limit switch is installed on the side plate, is provided with left and right sides limit switch at the gathering sill two ends.It is further characterized in that:
In rack-and-pinion transmission arranged outside case is arranged.
The present invention has increased limit conversion mechanism for cutting head front-rear linkage tilting member, is used for linkage to swing spacing control accurately; Flexible for installation, control is convenient, and installation and maintenance are convenient, and equipment dependability is good, the precision height.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As Fig. 1 and shown in Figure 2, end at power transmission shaft 8 is fixed with gear 11, and tooth bar 12 1 sides that mesh with gear 11 are equipped with the axis of guide 13, and opposite side is equipped with initial point sensing chip 15, gathering sill 14 is installed on the side plate of pedestal, the axis of guide 13 horizontal slip in gathering sill 14.During real work, power transmission shaft 8 rotates, make the gear 11 that its end is installed rotate, tooth bar 12 and gear 11 engagements, drive is installed in tooth bar 12 move left and right in gathering sill 14 on the axis of guide 13, initial point square limit switch 16 is installed on the pedestal, is designated as the work origin of linkage when initial point sensing chip 15 contacts with initial point square limit switch 16; Be provided with the capable limit switch 17 of left and right sides cylinder at gathering sill 14 two ends, when the capable limit switch 17 of tooth bar 12 and two ends cylinder contacted, control motor 7 was oppositely exported, and realizes the backswing of linkage.Adopt 18 pairs of said mechanism of case to carry out dust seal.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
Claims (2)
1. limit conversion mechanism of five-shaft steel tube intersection line cutter, pass through pivotally connected horizontal upper junction plate on the pedestal of cutting head front-rear linkage tilting member, lower connecting plate and vertical front swing arm, the parallelogram linkage that rear-swing arm constituted, at described pedestal fixed installation motor, its output shaft is connected with rear-swing arm by power transmission shaft, it is characterized in that: be fixed with gear at described transmission the tip of the axis, with tooth bar one side of gears engaged the axis of guide is installed, opposite side is equipped with the initial point sensing chip, axis of guide horizontal slip in the gathering sill of base side boards, the initial point limit switch is installed on the side plate, is provided with left and right sides limit switch at the gathering sill two ends.
