Abstract
The invention discloses a limiting device capable of controlling cutting of an arc part groove, which comprises a telescopic rod, a fastening device sleeve, a rolling bearing and a semi-automatic cutting machine, wherein the telescopic rod is fixedly connected with the fastening device; a cutting gun of the telescopic link semi-automatic cutting machine is arranged on the front side of the semi-automatic cutting machine and is contacted with the surface of the arc-shaped steel plate; the sleeve of the fastening device can apply acting force to the telescopic rod to control the telescopic length of the telescopic rod. The semi-automatic cutting machine is characterized in that a rolling bearing of the semi-automatic cutting machine after being modified is contacted with the bottom of the edge of the arc-shaped steel plate, the distance of a gun head of the cutting machine relative to the edge of the arc-shaped steel plate is always kept unchanged, and therefore the requirement of smooth cutting track is met to guarantee continuous operation of groove cutting work and guarantee groove cutting quality of the arc-shaped steel plate.
Description
Technical field
The present invention relates to a kind of limiting device of controllable cutting arc part groove, which belongs to steel construction part and adds
Work technical field.
Background technique
Nowadays, steel structure bridge mainly carries out processing and fabricating by the way of welding, to guarantee loading inside weld seam
And force request after appearance of weld, need to open up welding groove to meet design and related specification requirement.For most of steel knots
For structure bridge, for convenience of live practice of construction, roof and floor setting-out shape is consistent with bridge linear substantially, so its slope
The cutting route and non-rectilinear of mouth, but curve identical with bridge linear.
Cutting for this curve slope, conventional construction technique there are mainly two types of mode:
1) using polygometry setting-out control traveling orbit angle, achieve the purpose that curvilinear cut, but broken line instead of curve
It causes cutting quantity uneven, later period assembly process is had some impact on；
2) curve track is used, this kind of method is more demanding to trajectory accuracy, and orbital data is excessively single, it has not been convenient to become
Change, does not have generality.
Summary of the invention
The purpose of the present invention is providing kind of a limiting device for controllable cutting arc part groove, cuts to realize to groove
Cut the raising of precision.
To achieve the above object, the technical solution adopted by the present invention is a kind of limit of controllable cutting arc part groove
Device, the limiting device include telescopic rod 1, clamp device 2, clamp device casing 3, rolling bearing 4 and semi auto cutting machine 5；
Connect in the cutting gun of the installed in front telescopic rod 1 of semi auto cutting machine 5, semi auto cutting machine 5 with the surface of curved plate 6
Touching；Clamp device casing 3 can apply active force to telescopic rod 1, control the collapsing length of telescopic rod 1.
Clamp device casing 3, the at L-shaped bar of shape between telescopic rod 1 and clamp device casing 3 are installed in the end of telescopic rod 1
Part, clamp device 2, which is connected through a screw thread, to be mounted in clamp device casing 3, clamp device 2 pass through clamp device casing 3 after,
2 end of clamp device is equipped with rolling bearing 4, and clamp device 2 can be connected through a screw thread realization to rolling bearing 4 and curved plate
Elasticity between 6 is adjusted.Rolling bearing 4 is mounted on the bottom of curved plate 6, and the edge pad of curved plate 6 is rolling
The side of bearing 4.
The length of telescopic rod 1 is greater than the length 10mm of 5 bottom of semi auto cutting machine.
Compared with prior art, the cutting track of semi auto cutting machine is limited by part own profile to be cut, more
Add convenience, be applicable in, and improves work efficiency.
Detailed description of the invention
Fig. 1 is a kind of limit device structure schematic diagram-main view of controllable cutting arc part groove.
Fig. 2 is a kind of limit device structure schematic diagram-side view of controllable cutting arc part groove.
In figure: 1, telescopic rod, 2, clamp device, 3, clamp device casing, 4, rolling bearing, 5, semi auto cutting machine, 6,
Curved plate.
Specific embodiment
As shown in Figure 1, a kind of limiting device of controllable cutting arc part groove, which includes telescopic rod 1, fastening
Device 2, clamp device casing 3, rolling bearing 4 and semi auto cutting machine 5.
After semi auto cutting machine is reequiped in setting in Fig. 1, semi-automatic cutting down side is increased into telescopic rod 1, makes to stretch
1 end of contracting bar exceeds semi-automatic cutting motor spindle 10mm, and installs clamp device casing 3, the at L-shaped bar of shape in telescopic rod end
Part.And elasticity adjustment is carried out for rolling bearing 4 with clamp device 2, slope is cut to control with rotary fixture casing 3
The angle of mouth.
The advantages of present apparatus, is rolling bearing 4 and 6 edge of curved plate by the semi auto cutting machine after reequiping
Bottom connection touching, limitation cutting machine gun head remains constant relative to the distance of the edges of boards of curved plate 6, to reach cutting
The requirement of smooth trajectory guarantees the beveling and cutting quality of curved plate 6 to guarantee that beveling and cutting work can be carried out continuously.
