Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a work table having a cutting member alignment means,

The present invention relates to a work table provided with alignment means for aligning a cutting member such as a welding base material or welding specimen of various materials to a workbench so that the cutting member is precisely inserted and fixed to a workbench .

Generally, an automatic cutter is a machine that automatically cuts a steel sheet into a straight line, a curved line, a circle, or any other shape while automatically moving a torch by a power, and has a merit that the cut surface is clean and the cutting speed is fast. Depending on the kind of gas supplied to the automatic cutter, various kinds of gases are mainly used. Plasma (air), oxygen and acetylene, oxygen and LPG are mainly used.

The gas cutter is automatically cut along the rails fixed to the work table by the power source while automatically cutting the cutting members fixed to the work table, and is mainly used for cutting the cutting members into straight lines.

The prior art reference 1 shown in Fig. 1 has a) a perspective view and b) a right side view. Specifically, a die 1 having a leg 2 is formed, and a base 3 (lower plate) of a plate shape is formed on the die 1. A long groove portion 6 is formed on the base 3 (Upper plate) constituting the mounting table 4 constitute a mounting table 4

A gas cutter (not shown) is installed in the groove 6 of the mounting table 4. An assembly hole 5 is formed in the groove 6 of the mounting table 4 and a gas cutter having a rail is installed in the assembly hole 5.

A commercially available gas cutting machine is equipped with a rail capable of linear motion itself, so that the cutter can move left and right along the rail. Therefore, when the cutter equipped with the rails is assembled to the assembling hole 5, the cutter is installed so as to be movable in the left and right directions.

On the other hand, a wiring holder 8 is installed through the rear of the mounting table 4. The wiring holder 8 is used for arranging wires by cutting wires for cutting the gas cutters or the like so as not to interfere with the cutting operation of the gas cutters by the wires during the gas cutting operation.

On the front of the base 3, a collection box 10 is integrally or preferably detachably installed. In the collection box 10, a reservoir 11 is slidably installed in a drawer. That is, the die 1 is formed with a rectangular storage space 13 at a front portion thereof, and the storage space 13 is a storage space for the storage container 11.

In the lower part of the collection box 10, a footrest 20 configured to be pressed by foot is provided. When the pedestal 20 is pushed up and the pedestal 23 is pushed up around the shaft 22 formed on the inner and outer legs 31 of the die 1, the pedestal 4, which is in contact with the upper end of the pedestal 23, Push up. One end of the mounting table 4 is installed to penetrate the wiring holder 8 so that the mounting table 4 is guided along the wiring holder 8 and is raised upward. Thereafter, a clearance space is formed between the base 3 and the mounting table 4, so that the workpiece 25 (cutting member) to be cut is inserted into the clearance space. When the foot holding the foot plate 20 is released, The mounting table 4 on which the cutter is mounted descends to hold the workpiece 25 with its own weight. Thereafter, the gas cutting machine cuts the workpiece 25 while linearly moving along the rail on which it is mounted. It is a matter of course that the base 3 is formed in a passage, a through hole or a space capable of vertically moving up and down the platform 23. In addition, by-products such as a large amount of sludge generated during the cutting operation are collected in the reservoir 11, and the collected sludge or the like removes the reservoir 11 by pulling out the reservoir 11.

However, when the cutter is inserted and fixed between the upper and lower plates of the workbench, the cutter is inserted in a state of being twisted or crooked, If the cutting operation is performed by the automatic gas cutting machine after the top plate is lowered and the cutting member is fixed, the cutting member becomes a rhombus shape instead of a right square after cutting.

The welding work of the plate-shaped welding specimen cut by the cutting machine is a method of welding a pair of welding specimens against each other on a welding specimen fixing frame formed on the welding workbench and then welding the welding specimen with a welding machine. The welded specimen to be welded must be precisely fixed in the rectangular fixture only when the crest is square. Therefore, if the welding specimen, which is the cutting member cut by the cutting machine as described above, is not a right-angled rectangle, it is not possible to accurately fix the welding specimen to the welding specimen fixture of the welding workbench, It is difficult to precisely fix the part and the welding operation is inaccurate, resulting in a large number of welding defects.

In addition, for the welded specimen welded as described above, the weld bead formed on the welded portion must be grinded by a screwdriver before the bend test. In order to grind the welded specimen, the welded specimen should be fixed to a vise, a fixing jig, or the like. At this time, both ends of the welding specimen are inserted and fixed between the vice or the fixing jig, where the surfaces symmetrically opposed to each other are formed horizontally, and the welding specimen must be a rectangle to be fixed accurately. Therefore, it is difficult to accurately fix the welding specimen to the vise or the fixing jig unless the welding specimen, which is a cutting member to be cut by the cutting machine, is a rectangle or a square, as described above. There is a problem that the safety of the operator can not be assured.

Here, the aligning means will be described in detail since the aligning means, which is a feature of the work table provided with the cutting member aligning means according to the present invention, is additionally constituted.

2 to 8, the guide member 110 has a long shape extending along the left and right longitudinal direction of the work table 100. Both ends of the guide member 110 are parallel to the front surface of the work table 100, As shown in Fig. The guide member 110 is preferably installed on the upper plate 102 of the work table 100 but may be installed anywhere on the work table 100 such as the lower plate 103 and the support table 101. However, the rear surface of the conveying member 130, which will be described later, may be provided so as to be in contact with or close to the front surface of the work table 100, as shown in FIG. The guide member 110 may be fixed to the work table 100 by bolts or may be fixed by welding and may be made of the same material as that of the work table 100 or the upper and lower plates 102 and 103 However, a material which can be fixed even if it is made of different materials can be applied.

In particular, as shown in FIG. 9, a pair of fixing members 120 protruding and fixed to one side of the work table 100 are formed so as to be symmetrical while facing each other, Both ends of the member 110 are fixedly coupled to each other and the guide member 120 is spaced apart from the work table.

2 to 6, the rear surface of the conveying member 130 corresponds to the front surface of the work table 100 and both side surfaces extending forward from the rear surface are formed at a right angle to the front surface of the work table 100 And a guide ring 132 protruding from the rear surface in the direction of the guide member 110 is formed to be coupled to the guide member 110 so as to surround the guide member 110. The guide ring 132 guides the conveying member 130 to slide along the longitudinal direction of the guide member 110. Since the transfer member 130 is slidably moved along the left and right sides of the front surface of the work table 100, it is preferable that the rear surface of the transfer member 130 is slidingly moved in a state of being in contact with the front surface of the work table 100 Do. This is because the side surface of the cutting member 150 is brought into contact with the guide surface 131 of the conveying member 130 so that the side surface of the cutting member 150 is perpendicular to the front surface of the work table 100 The guide surface 131 of the conveying member 130 is advantageously positioned perpendicular to the front surface of the work table 100 and the side surface of the cutting member 150 which is in contact with the guide surface 131 is naturally And is positioned at a right angle to the front surface of the work table 100. However, even if the rear surface of the conveying member 130 is installed to be spaced from the front surface of the work table 100, the conveying member 130 slides left and right along the guide member 110, The guide surface 131 can be positioned at a right angle.

8, since the guide ring 132 of the conveying member 130 is freely slidably moved left and right along the guide member 110, the conveying member 130 can be inserted into the work table 100 The operator grips the transferring member 130 with one hand of both hands and slides the same while holding the cutting member 150 with the other hand to hold the cutting member 150, The side surface of the cutting member 150 is aligned at right angles to the front surface of the work table 100 when the guide surface 131 of the member 130 is pushed by the guide surface 131. The cutting member 150 is inserted between the upper plate 102 and the lower plate 103 of the work table 100 while the side surface of the cutting member 150 is aligned perpendicular to the front surface of the work table 100 The cutting member 150 is inserted and aligned at right angles between the upper plate 102 and the lower plate 103 of the work table 100. The upper plate 102 is lowered by its own weight when the foot plate 142 of the lifting means 140 is released from the foot plate 142. That is, When the side of the cutting member 150 is fixed at a right angle between the upper plate 102 and the lower plate 103 of the work table 100 while pressing the cutting member 150 downward, (110) to the edge of the work table (100) to prevent interference with the cutter (C). When the cutting member 150 is fixed to the work table 100 as shown in FIG. 7, the left and right lengths of the work table 100 along the rail R fixed to the upper surface of the work table 100, The cutting member 150 is cut by the cutting gas ejected from the cutting torch T of the cutter C moving linearly along the cutting direction of the work table 100 The horizontal direction is horizontal to the left and right longitudinal direction of the front surface.

That is, according to the present invention, by inserting the cutting member 150 with the guide member 110 and the conveying member 130 in such a manner that the cutting member 150 is aligned at right angles between the upper plate 102 and the lower plate 103 of the work table 100 It is not inserted arbitrarily by the operator's eye but is mechanically correctly inserted and fixed. Therefore, the cutting member 150 fixed to the work table 100 is precisely linearly cut and cut by the cutter C so that the welded specimen becomes a right-angled rectangular shape. Therefore, And it is fixed accurately to the vise and the fixing jig at the time of the operation, thereby achieving the object and effect to be achieved by the present invention.

Since the conveying member 130 is slidably moved along the guide member 110, it is preferable that the conveying member 130 is made of a light material and durability is secured. However, synthetic resin or wood is suitable, and various materials such as steel and composite materials can be applied have.

The cutting sludge generated during the cutting operation falls on the sludge collection box B provided at the lower part of the front surface of the work table 100 and is collected when the amount of cutting sludge collected in the sludge collection box B is large. .

An aligning protrusion 135 is formed at a right angle to the left guide surface 131 of the conveying member 130 which is slid right and left along the guide member 110 for a right handle as shown in FIG. Or an aligning protrusion 135 is protruded at right angles to the right guide surface 131 of the conveying member 130 for a left-handed person as shown in (D) Alignment protrusions 135 are protruded perpendicular to the guide surfaces 131 at both ends of the left and right sides of the conveying member 130 so that both hands can be applied. The side surface of the cutting member 150 is aligned at right angles to the front surface of the work table 100 by the guide surface 131 of the conveying member 130, 130 are aligned horizontally with respect to the front surface of the work table 100 by the alignment protrusions 135 formed on the work table 100. Accordingly, the cutting member 150 can be more accurately aligned.

In addition, the alignment protrusion 135 formed on the transfer member 130 can be easily operated by anyone, regardless of right or left handedness.

10 and 11, the fixing member 120 is disposed on one side of the work table 100 and is symmetrical with a pair of spaced apart members facing each other. In place of the guide member 110, The conveying member 130 is formed so as to penetrate through the left and right sides in accordance with the shape of the guide rod 111. The conveying member 130 is formed with a round bar or a pipe- A guide hole 137 is inserted into the guide rod 111 and the conveying member 130 is slidably moved through the guide rod 111. [ The reason why the guide hole 137 of the conveyance member 130 is inserted into the guide rod 111 and slidably moved is that the conveyance member 130 is inserted into the guide rod 111 fixed to the work table 110, The conveying member 130 can be separated from the work table 100 or can not be separated from the work table 100, so that the cutting member 150 can be aligned more stably.

Further, as shown in FIG. 12, the pair of guide rods 111 are formed to prevent sagging of the conveying member 130 when sliding.

13, the guide member 110 has an elongated coupling groove 112 formed along the longitudinal direction of the guide member 110, and the conveying member 130 is protruded from the guide ring 132 And the engaging protrusion 136 is formed so as to have a 'C' shape on the side surface with the guide ring 132.
