Description

[Detailed Description of the Invention] [Industrial Application Field] - The second invention is a method for forming holes for fixing metal shapes such as hat wood and cut wood on a predetermined surface to be drilled on the old edge of a wall of a building. The present invention relates to a punching device for punching a hole at a location.

[Prior art] For example, when fixing a conical concrete sheet on the top of a building's side wall by covering it with a metal mold such as aluminum formed into a gap-like cross-sectional shape, the first step is to cover one side of the side wall. A reference straight line (reference corner) is set by setting six reference points at both ends and stretching a thread between both reference points to measure the corner. Using this reference slit, measure the longitudinal and widthwise dimensions using a tape measure, and mark the drilling position based on the predetermined fixing bracket installation position (S division diagram).・According to Gisig), one hole for an anchor bolt is drilled at each position for each installation of the side wall soil surface using a hunt drill or τ-moving L/rill. After drilling, embed a Fisher anchor in each hole and fix the fixing fittings (holders or fasteners) with wood 17° or bolts.
In this way, the fixing metal fittings are fixed one after another on the top surface of the outer wall, and then the gap-shaped shade wood is covered with the top surface of the outer wall and fixed by fitting with the fixing metal fittings. In some cases, the fixing fittings and the cap wood may be further engaged with hook bolts or the like.

``Problems to be Solved and Aimed by the Invention J - Even though the wall materials of buildings look like straight lines, most of them have some bends, and the edges of the wall materials are (total length 1ζ width) and are not necessarily parallel.

On the other hand, there are metal shapes such as 1i aluminum that are roll-formed into a predetermined cross-sectional shape and are used to attach hats, cut wood, or curtain boards to the edges of wall materials, and these metal shapes cannot be bent. A trough has a predetermined width that is wide enough to cover the bend in the edge of the wall material.

Therefore, conventionally, metal shapes are applied to the edges of wall materials as described above. In addition, it is necessary to perform drilling work for each hole by marking the drilling position and using a drill.The reality is that work 1 requires a high degree of skill and takes a long time.

This invention is highly mature &! An object of the present invention is to provide a drilling device that can simplify the drilling work during installation of metal molds to the edge of the material without requiring additional work, and by improving the inefficiency of the drilling work. It is.

[Means for Solving the Problems] According to the present invention, in order to achieve the above-mentioned problems, a plurality of holes are formed at intervals along the longitudinal direction of the perforation target surface of the edge of the wall material. hole yfi: A drilling device for drilling is movable along the longitudinal direction 1 of the surface to be drilled; indexing the drilling position and drilling y; A drilling device consisting of a reference point device arranged at a fixed position relative to the target surface is viewed.

The reference point device includes a beam irradiation means that irradiates a light beam along the longitudinal direction of the surface to be drilled from a predetermined reference point position in the width direction of the surface to be drilled, and a beam irradiation means that irradiates a light beam along the longitudinal direction of the surface to be drilled, and a beam irradiation means that irradiates a light beam along the longitudinal direction of the surface to be drilled. reflecting means having an optical reflecting function, which are removably attached to the end position of the desired working range of the body or separately of the surface to be drilled;
The work cart also includes a work cart locking means for releasably fixing the work cart to the wall (O), and a work cart locking means for releasably fixing the work cart to the wall (O), and a locking means for releasably fixing the work cart to the wall (O), and a locking means for releasably fixing the work cart to the wall (O), and a locking means for releasably fixing the work cart to the wall (O); a drill cart guided and supported by a work cart; a drill cart locking means for releasably locking the 8-movement of the drill cart to the work platform group;
v1. A power drill device supported by the drill cart so as to be able to approach and leave the surface to be drilled in the direction of the drilling axis, a drill feeding device that feeds the drill blade of the power drill device in the direction of the drilling axis, and Optical means is provided between aiming means, which is fixed and displays the receiving position of the light beam in the sliding direction of the drill cart when receiving the light beam from the beam irradiation means, and the reflecting means, which is fixed to the work cart. The work cart is equipped with a length measuring means for non-contact length measurement, and this work cart pairs with the reference point device to index the drilling position in the working range of the surface to be drilled and perform drilling. be.

[Operation] The drilling operation by the drilling device of the present invention eliminates the need to set a reference slot by tensioning a thread between both ends of the surface to be drilled in the longitudinal direction, as in the conventional method. Further, the work cart makes it possible to sequentially drill a plurality of holes spaced apart in the longitudinal direction on the surface to be drilled, while measuring the length and indexing the drilling position with the reference point device.

That is, in the drilling operation using the drilling device of the present invention, first, the beam irradiation means and the reflecting means of the reference point device are fixed on the longitudinal direction of the surface to be drilled, for example, on the negative end side, and the work cart is fixed in the longitudinal direction of the surface to be drilled. arranged so as to be movable along the direction.

The beam irradiation means irradiates a light beam along the longitudinal direction of the surface to be drilled from a predetermined reference point position in the width direction of the surface to be drilled, and provides a reference light beam in place of a conventional reference corner.

The reflecting means has an optical reflecting function in a direction parallel to the light beam, and is part of an optical system for optical non-contact length measurement by the length measuring means attached to the work trolley. This length measuring means may be, for example, a well-known infrared length measuring device, in which case the reflecting means is a reflecting prism,
It is also possible to configure the length measuring means using other laser interferometers or the like. The length measuring means measures the distance between the reflecting means and the work trolley in a direction parallel to the light beam, and determines the drilling position in the longitudinal direction of the drilling target surface from the length measurement result obtained from the indicator etc. The position of the cutting edge of the drill device mounted on the machine can be manually adjusted on the spot. When the length measurement results indicate that the hole is at a predetermined drilling position, the work cart is fixed to the wall material by the work cart locking means.

The light beam from the beam irradiation means is a reference light beam corresponding to the reference point position in the width direction of the surface to be drilled, that is, the reference corner, and the aiming means attached to the drill cart receives this light beam and adjusts the received light beam. The position, that is, the reference point position is displayed. Therefore, if you bring the work cart closest to the reference point device in advance and align the origin of the aiming means with the reference point position, the light beam receiving position of the aiming means will coincide with the origin at the drilling position in the longitudinal direction of the surface to be drilled. By sliding the drill cart in the width direction to position it, and in that state, locking the drill cart to the work cart by the drill cart locking means, the drilling position by the drill can be adjusted with respect to the reference point position at any position. Can be positioned.

After the drilling position has been determined in this way, the power drill device is fed in the direction of the drilling axis by the drill feeding means to drill holes in the wall material frame on the surface to be drilled. Once the hole has been drilled to a predetermined depth, the feed means is reversed to remove the drill bit from the hole, the work cart locking means is unlocked, the work cart is moved to the next longitudinal drilling position, and the length is measured. From the results of the means lock in the next longitudinal drilling position. Thereafter, positioning of the drill cart in the width direction and drilling are performed in the same manner, and by repeating this, a desired number of holes are drilled over the working range of the surface to be drilled.

In this way, the drilling work using the drilling device of the present invention does not require the setting of a reference slot by thread tension, which requires a high degree of skill, and the work of assigning and marking the drilling position based on this, and it is possible to determine the length measurement position in the longitudinal direction. Positioning and indexing in the width direction can be performed extremely easily by checking the display on the length measuring means and the instructions on the aiming means, and drilling can be performed using power immediately after positioning, greatly improving work efficiency.

In addition, if a drill device having a plurality of drill blades spaced apart in the width direction of the surface to be drilled is used, the number and spacing of the drill blades can be made to correspond to the plurality of holes of the aforementioned fixing fitting. The work efficiency is further improved because the holes for the fixing metal fittings can be drilled at one time.

A preferred embodiment of the punching device of the present invention will be described below with reference to the drawings.

When the light beam 24 from the laser beam irradiator 22 is received, a target 2 with an aiming gauge that displays the receiving position of the light beam 24 in the sliding direction of the drill cart 7 and a target 2 fixed to the work cart main body 6 is provided. The work is carried out with a length measuring device 3 etc. that performs optical non-contact length measurement for determining the position of the work chalk 10 by forming a reciprocating optical path of the infrared beam with the reflecting plate 23. The platform j@10 rides on the surface of the side wall 30 and moves on wheels 1.1, and is guided by sight rollers 13 attached to the tips of legs 12 provided below both sides of the work platform body 6. This is done by rolling the side walls, and the opening dimension of the legs 12 can of course be adjusted.

The drilling operation by the drilling device of this embodiment is performed as follows.
