Description
Technical Field
The method relates to the manufacturing application of all similar structure circle cutting.
Background
In the construction process of the steel structural member, the grouting hole cannot be formed in advance during blanking, generally, a method of cutting the member by using a handle is adopted after the member is formed, but the manufacturing precision of the method of cutting the handle is poor, and the roundness of the grouting hole and the quality of a cutting surface cannot be guaranteed. The cut surface is of poor quality and inconvenient to repair. The quality of the cutting surface after grouting has a great influence on the blocking welding of the grouting hole, so that the improvement of the cutting quality of the grouting hole is a problem which is to be solved by technicians in the field.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the existing construction method, the invention provides the grouting hole circle cutting tool which is simple to operate, high in efficiency and high in quality.
In order to achieve the above object, the utility model adopts the following technical means:
a circular cutting tool for a grouting hole comprises a cutting gun and a cutting gun fixing device, wherein the cutting gun fixing device is installed on a connecting rod, the connecting rod consists of a left supporting rod and a right supporting rod, and the cutting gun fixing device is installed at the outer ends of the left supporting rod and the right supporting rod; racks are arranged on the right supporting rod and the left supporting rod, the racks are meshed with the same gear, and a circle center positioning column is arranged below the gear.
The utility model provides a problem that grout hole was seted up to the component. The cutting guns on the two sides of the circle center are synchronously adjusted, and the operation is convenient. The invention saves labor, ensures the cutting quality of the grouting hole and reduces the links of repairing and polishing.
The circle center positioning column is provided with a threaded hole, the threaded hole and the circle center point are positioned on the same vertical line, a nut is installed in the threaded hole, a shaft hole is formed in the center of the gear, and the gear is arranged between the circle center positioning column and the nut.
The left supporting rod and the right supporting rod are provided with grooves along the length direction of the left supporting rod and the right supporting rod, the bottom plate in each groove is of a rack structure, and the width of each groove is matched with the thickness of each gear.
Drawings
FIG. 1 is an overall view of the present invention;
FIG. 2 is a schematic view of the connection structure at point A in FIG. 1;
fig. 3 is a structure view of the connection between the left and right support rods and the gears.
In the figure: the cutting torch fixing device comprises a cutting torch fixing device 1, a left support rod 2, a right support rod 3, a nut 4, a gear 5, a circle center positioning column 6 and a rack 7.
Detailed Description
The technical solution of the present invention will be described in detail, clearly and completely with reference to the accompanying drawings 1-3 and the specific embodiments. It should be understood that this embodiment is but one example of many specific embodiments of the invention and is not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. All other embodiments obtained by those skilled in the art based on the present embodiment without any creative efforts belong to the protection scope of the present invention.
The invention of the utility model provides a supporting structure, on one hand fixes the burning torch, on the other hand fixes the centre of a circle. Cutting is performed with support and positioning maintained. The cutting line is kept stable.
Specifically, the utility model discloses a scheme is: a circular cutting tool for a grouting hole comprises a cutting gun and a cutting gun fixing device 1, wherein the cutting gun fixing device 1 is installed on a connecting rod, the connecting rod consists of a left supporting rod 2 and a right supporting rod 3, and the cutting gun fixing device 1 is installed at the outer ends of the left supporting rod 2 and the right supporting rod 3; the left supporting rod 2 and the right supporting rod 3 are provided with racks 7, the racks 7 are meshed with the same gear 5, and a circle center positioning column 6 is arranged below the gear 5.
The circle center positioning column 6 is provided with a threaded hole, the threaded hole and the circle center point of the threaded hole are perpendicular lines, a nut 4 is installed in the threaded hole, a shaft hole is formed in the center of the gear 5, and the gear 5 is arranged between the circle center positioning column 6 and the nut 4.
When the length of the connecting rod part is adjusted, the supporting rod on one side is pulled, the gear is driven to rotate, and the supporting rod on the other side is synchronously linked. So as to achieve the relative and synchronous movement of the cutting guns at the two ends.
The utility model discloses an operation process as follows:
(1) the distance between the cutting torch fixing device and the circle center positioning column is adjusted according to the size of the grouting hole, the installation position of the cutting torch fixing device is not limited to the installation structure shown in the drawing, and the center position of the cutting torch fixing device can be arranged on the horizontal line with the gear by any simple structure. The distance between the cutting point and the central point can be adjusted in any mode to be easy to quantify. One of the cutting guns is equal to the radius of the grouting hole, and the other cutting gun is positioned synchronously.
(2) And a circle center positioning column is fixed through a top fastening nut and is placed at the circle center of the grouting hole to be cut.
(3) The cutting torch tip is arranged in the cutting torch fixing device and is ignited for cutting operation.
The scheme solves the problem that the grouting hole is formed in the component. The cutting guns on the two sides of the circle center are synchronously adjusted, and the operation is convenient. The tool saves labor for grouting hole cutting operation, ensures the cutting quality of grouting holes, and reduces the links of repairing and polishing.
The blockage welding flaw detection qualification rate of the grouting holes after grouting is finished is greatly improved, the production efficiency is greatly improved, the production cost is reduced, and the tool can be applied to cutting operation of all engineering grouting holes and has great practical popularization significance.
