Abstract
The utility model belongs to the technical field of pipe construction for petrochemical, electric power, coal, water delivery and the like, and provides axial adjustment mechanisms for toolbars of a pipe beveling machine. The pipe beveling machine is provided with two or more than two toolbars (5); an axial adjustment mechanism is arranged corresponding to each toolbar (5); an adjustment jackscrew (6) is arranged in each axial adjustment mechanism, and is positioned in a threaded hole axially machined along each toolbar; and a baffle (1) which is matched with the adjustment jackscrew (6) to adjust the axial position of each toolbar is arranged, is positioned in a tool rest (4) of the pipe beveling machine and corresponds to the adjustment jackscrew. The axial positions of the toolbars can be compared with the required size of bevels and the screw pitch value of the adjustment jackscrew, and the axial positions of the two or more than two toolbars on the pipe beveling machine are accurately and conveniently adjusted.
Description
Technical field
The utility model belongs to pipeline construction technology fields such as petrochemical industry, electric power, coal, water delivery, relates to a kind of mechanism for axial adjusting of tube groove machine knife bar.
Background technology
During pipeline welding according to the welding process requirement needs to pipe building up by welding groove; The pipe groove normally is made up of a plurality of line segments; This just requires to install on the cutterhead of tube groove machine a plurality of cutters and participates in the moulding that cutting could be accomplished the pipe groove simultaneously; According to the shaping and the groove dimensional requirement of the mouth of pipe, need do the adjustment of relative axial position to being installed in a plurality of knife bars on the cutterhead.Present adjustment mode is, behind the mouth of pipe trial cut, according to the actual measured results of mouth of pipe trial cut size; Knife bar is knocked in front and back; Estimate behind an axial internal clearance knife bar to be locked with bolt, continue trial cut, measure the trial cut size once more; Knock knife bar and locking once more, repeated multiple times just can cut out qualified groove like this.This adjustment mode wastes time and energy, and shaping and groove size be difficult to accurately to guarantee, knife bar produces displacement again when adjusting to after the size bolt locking sometimes, continues adjustment again.
The utility model content
The purpose of the utility model is the mechanism for axial adjusting that proposes a kind of tube groove machine knife bar; Make it can adjust the axial location of tube groove machine knife bar accurately; Thereby the axial location of the plural knife bar that the tube groove machine had is accurately adjusted, guaranteed the crudy of tube groove machine.
The utility model adopts following technical proposals to accomplish its invention task:
A kind of mechanism for axial adjusting of tube groove machine knife bar, described tube groove facility have two or more knife bar; Corresponding each knife bar is provided with an adjustment jackscrew in the described mechanism for axial adjusting, and described adjustment jackscrew is arranged in along the screwed hole of the axial processing of knife bar; Be provided with and adjust jackscrew and cooperate the baffle plate that the axial location of knife bar is adjusted, described baffle plate is positioned at the knife rest and the setting of corresponding adjustment jackscrew of tube groove machine.
The mechanism for axial adjusting of the tube groove machine knife bar that the utility model proposes; Can compare according to the axial location of knife bar and the pitch numerical value that requires size and adjustment jackscrew of groove operation; The axial adjustment of knife bar is quantized, and the tube groove machine is had two or above knife bar are adjusted accurately and easily.
Description of drawings
Accompanying drawing 1 is the structure chart of the utility model.
Among the figure, 1, baffle plate, 2, cutterhead, 3, clamping screw, 4, knife rest, 5, knife bar,
6, adjustment jackscrew, 7, groove..
The specific embodiment
In conjunction with accompanying drawing and embodiment the utility model is explained:
As shown in Figure 1, among this embodiment, the tube groove facility have two knife bars; Corresponding two knife bars are provided with the mechanism for axial adjusting of a knife bar; The structure of the mechanism for axial adjusting of two knife bars is identical.Mechanism for axial adjusting with one of them knife bar is that example is explained; The knife bar 5 of corresponding required adjustment, along the axial thread mill drilling of knife bar, the rear end of said screwed hole can be unthreaded hole; The adjustment jackscrew 6 that is provided with is arranged in screwed hole; In the knife rest 4 of tube groove machine, baffle plate 1 is set, baffle plate 1 and knife bar 5 corresponding settings.
The tube groove facility have two knife bars, and these two knife bar co-operation are cut two sets of curves of groove respectively.Described two knife bars are 180 ° of distributions on circumference, axially requiring to have a relative position accurately.When the guiding mechanism of employing the utility model is adjusted the axial location of two knife bars of tube groove machine; At first according to the requirement of mouth of pipe shaping and groove size; Two knife bars are done preliminary axial dimension adjustment with respect to cutterhead 2; Then pipe is carried out trial cut, measure the actual trial cut size of groove 7 and do contrast with the size that requires of groove again, draw the axial error value of each size of groove; The top of adjustment jackscrew 6 is contacted with baffle plate 1, go out angle and the rotation direction that jackscrew is adjusted in required twisting according to the pitch numerical computations of adjusting jackscrew 6, slightly unclamp clamping screw 3, twisting adjustment jackscrew 6 can make knife bar move axially required distance to mouth of pipe direction; If need knife bar 5 to move inwards relative to knife rest, then need to push inward moving knife bar 5 and make the tops of adjustment jackscrews 6 touch baffle plate 1 with hand, at this moment tighten clamping screw 3 and get final product.Because adjustment jackscrew 6 contacts with the baffle plate 1 of bottom, knife bar hole; When with clamping screw 3 locking knife bars 5; The knife bar 5 of adjusting the position is subjected to displacement, improved the operating efficiency that beveling machine is adjusted knife bar at the scene greatly, improve the shaping size and the groove dimensional accuracy of the mouth of pipe.
Claims (1)
