Description

{Apparatus for automatically assembling curved angle template}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to curved processing in shipbuilding, and more particularly, to an apparatus for automatically assembling a curved processing template required to shape an outer plate into a curved shape in a shipbuilding process.

The bending operation is the operation of creating a desired curve by using the stress generated when heating and cooling an iron plate using a heat source such as a gas torch. In general, the operator manually heats and cools the heating wire along the heating wire using a gas torch, and after a certain operation, measures the shape of the song using a number of templates in which the shape of the part to be measured is set to form the target song.

As for the template assembly used for measuring the amount of curvature, the worker directly checks the information given in the drawing (measured part and height value) by printing a paper drawing, adjusts the height manually, and fixes the bolts and nuts to assemble it according to the target member. In the case of a typical container ship, there are about 800 members that require curved processing, and each member has at least 5 or more template measuring parts. The template has 3 to 14 individual height adjustment bolts, and the operator repeats the simple operation of fastening/dismounting the bolts/nuts.

In addition, since the amount of curvature is measured with the template, it has a great influence on the quality of the curved member and the welding control during block welding and between blocks assembling the hull.

As prior art documents that can be referenced in this regard, Korean Utility Model Publication No. 0438057, Korean Patent Publication No. 2018-0039944, etc. are known.

The former includes an insert-type fixing means that can penetrate and combine or disassemble as if threading a number of curvatures of a certain curvature, and is expected to replace the curvature plate and increase the working speed. The latter is expected to prevent excessive processing of work members and obtain high-quality grain products by ensuring that LPG gas and oxygen are constantly supplied to the torch for grain processing and the flame is uniformly sprayed.

However, since the above-mentioned prior literature also fundamentally depends on the manual power of the operator, it exposes limitations in improving quality and productivity.

Hereinafter, an embodiment of the present invention will be described in detail based on the accompanying drawings.

The present invention proposes with respect to an apparatus for automatically assembling a curved processing template as an object. It is related to, but not necessarily limited to, the process of forming the shell plate into a curve in the process of building a ship.

In FIG. 1 , reference numeral 10 is a template for measuring the amount of curvature that is an object, and is composed of a barten bar 11 , a long member 12 , and an end member 13 . The batten bar 11 made of a flexible resin material is connected via a plurality of end members 13 and hinges 14 . The plurality of end members 13 are connected to the long member 12 having a length similar to that of the batten bar 11 via a fastening member 15 . The fastening member 15 is coupled as a bolt/nut so that the batten bar 11 maintains a set curvature.

Conventionally, the operator adjusts and assembles the template manually with reference to the drawings before the bending operation, and the size, shape and amount of the template are all different according to the type of ship and the work member. Due to the error occurred in the template assembly, it affects the block assembly and block mounting.

The device of the present invention is equipped with a fixing unit 30, an operating unit 40, and a control unit 50 on the main body 20, and performs adjustment and assembly of the template 10 in an automated process.

According to the present invention, the main body 20 forms a structure having a work table 21 and a guide rail 25 . The work table 21 is formed with a sufficient length and width to enable gripping of a loaded object. The guide rail 25 is installed on the upper side of the work table 21 to always maintain parallel with the object.

In addition, according to the present invention, the fixing part 30 has a structure to hold the object via the upper clamp 32 and the lower clamp 36 on the work table 21 . The template 10, which is the object, is manually loaded on the workbench 21 in a state in which the batten bar 11, the long member 12, and the end member 13 are temporarily assembled by the hinge 14 and the fastening member 15. . The upper clamp 32 and the lower clamp 36 are installed in the same number on the work table 21 . The upper clamp 32 holds the batten bar 11 and the lower clamp 36 holds the long member 12 .

According to the detailed configuration of the present invention, the fixing part 30 is characterized in that it supports the plurality of upper clamps 32 arranged at regular intervals to be able to individually move in a straight line. In order to adjust the batten bar 11 to the set curve in the template 10 loaded in the provisionally assembled state, individual linear motion of the upper clamp 32 should be accompanied. The curvature setting of the batten bar 11 is gradually completed while sequentially adjusting the position from the upper clamp 32 of one side to the upper clamp 32 of the other side.

At this time, it is preferable to reduce trial and error by the algorithm of the control unit 50 to be described later because the position change of the end member 13 through any one of the upper clamps 32 affects the other end members 13 .

According to the detailed configuration of the present invention, the main body 20 is characterized in that it is provided with an auxiliary tool 23 for supporting the fastening bolt between the plurality of lower clamps 36 arranged at regular intervals.

Referring to FIG. 2 , it shows a state in which the assembly jig 22 is installed at positions opposite to the plurality of upper clamps 32 . The assembly jig 22 is formed with sufficient width and length to support the long member 12 of the template 10 . The assembly jig 22 is provided with a plurality of auxiliary tools 23 arranged at the same interval as the end member 13 on the upper surface. The auxiliary tool 23 is formed in the form of a concave groove of a square shape that engages with the head of the fastening bolt. Since the long member 12 and the end member 13 in the provisionally assembled state are in a state in which the bolt is gripped by the auxiliary tool 23, the template 10 can be completed by tightening only the nut from the top.

In addition, according to the present invention, the operation unit 40 moves the nut fastener 45 on the guide rail 25 and forms a structure for fastening the object to form a set shape. When the batten bar 11 achieves the set curvature by adjusting the position of the individual upper clamp 32, the long member 12 and the end member 13 are tightened with the fastening member 15 to complete the set shape of the template 10. . The nut fastener 45 moves while maintaining parallel with the assembly jig 22 and sequentially tightens the nuts temporarily coupled on the bolts supported by the auxiliary tool 23 .

According to the detailed configuration of the present invention, the operation unit 40 includes an inclination driving unit 41 for inducing an inclination motion of the work table 21 and an LM actuator 43 for inducing a linear motion of the upper clamp 32. characterized in that

In FIG. 2 , the inclined driving part 41 , the LM actuator 43 and the nut fastener 45 constituting the operation part 40 are shown. The inclined driving unit 41 causes the rear end to rise around the hinge of the front end of the work table 21 . When the work table 21 is maintained in an inclined state, it is convenient for the operator to load/unload the template. The LM actuator 43 is connected to each upper clamp 32 to induce linear motion. The LM actuator 43 uses an electric actuator capable of more precise control than a hydraulic/pneumatic cylinder.

In addition, according to the present invention, the control unit 50 has a structure in which the fixing unit 30 and the operating unit 40 are controlled by a set algorithm. The control unit 50 is installed on one side of the main body 20 and processes input and output in a touch screen manner. The control unit 50 includes an external server that stores 3D data of various members of the server. The control unit 50 transmits data I/F and design song information between design data and equipment.

According to the detailed configuration of the present invention, the control unit 50 includes a control panel 51 equipped with a control circuit, a position sensor 53 for detecting a position change of the upper clamp 32, and a label output machine for printing information about an object. (55) is provided.

The control unit 50 is based on a control panel 51 equipped with a microprocessor, a memory, and an input/output interface. The control panel 51 is equipped with a recognition means (bar code, QR code, marker, etc.) for reading the drawing in addition to the touch screen that can input the information of the object. The position sensor 53 detects a position change of each upper clamp 32 by a laser method. The upper clamp 32 has a measuring hole 34 so that the laser light of the position sensor 53 is transmitted. The label output machine 55 outputs information such as arc lines/members/curves in the form of printed matter.

As an example of the operation, the operator enters the reference number of the object through the control panel 51 or receives drawing information to complete the preparation by automatically loading design information for assembling the object. After that, as shown in Fig. 4(a), the workbench 21 of the main body 20 is tilted and the temporarily assembled object (template) is held by the upper clamp 32 and the lower clamp 36, and the workbench 21 as shown in Fig. 4(b). After returning to the horizontal, operation is started through the control panel (51). The control panel 51 adjusts the batten bar 11 to the set curvature by changing the position of each upper clamp 32 while inputting the information of the position sensor 53 through the microcomputer control. When the curvature setting of the batten bar 11 is completed, the bolt/nut fastening of the fastening member 15 is completed by operating the nut fastener 45 .

As described above, the present invention is based on the design data (arc line/block/member information, template position, curvature, member direction, etc.) of the object to be processed, so it automatically forms, measures, assembles and inspects the curvature using the equipment without the manual work of the operator. etc. are performed. Accordingly, it is possible to minimize the assembly error by the operator and to minimize the problems that may occur in the subsequent process.

The present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such variations or modifications fall within the scope of the claims of the present invention.
