{STOPPER STRUCTURE FOR WORK REST}

The present invention relates to a stopper structure for a shelf vibration damping element, and more particularly, to a stopper structure for a shelf vibration damping structure having an improved structure to prevent a phenomenon in which a damper is pushed rearward due to an impact generated during placement of a roller, Stopper structure.

Generally, in the case of roll forming, which is a steel material, a primary machining operation is performed in a computerized numerical control (CNC), and then a finishing machining operation is performed in a general purpose lathe.

[0002] A lathe is a machine that processes a workpiece such as a roll by rotating the workpiece with the toolbelt while fixing and rotating it to the main shaft and the tailstock, and is provided with a copy lathe or a CNC machined workpiece Is mounted on a shelf, and then a finishing process is performed.

As an accessory device, there is a work rest which fixes the work roll as a tool to prevent the bending of the workpiece between the tailstock and the main shaft, Respectively.

The anti-vibration plate is structured to move forward and backward in the 90 ° direction intersecting the workpiece on the lathe bed table.

At this time, there is a work process in which the roll as the workpiece is rotated as the rotational force is transmitted from the drive unit of the main shaft, and the outer peripheral surface of the roll is cut by the bite installed close to the outer circumferential surface thereof.

However, even if a work roll, which is a workpiece, is clamped and fixed by using an existing shelf, the impact may be transmitted during the process of laying the heavy roll on the floodgate so that the floodgate may be pushed backward.

In this case, since the work roll, which is a workpiece, can not be fixed at an accurate position, a machining error is generated, and when the end portion is retracted during the center machining operation,

In addition, since it is necessary to repeat the hoisting and jacking work several times by using a crane for precise laying work of the roll, not only is the work time consumed, but also there is a fear that the roll and the lathe collide with each other due to the work in a narrow space have.

The object of the present invention is to provide a stopper structure for a shelf vibration damping structure, which is improved in structure to prevent backward pivoting occurring during clamping operation of the shelf vibration damping element have.

In order to achieve the above object, the present invention provides an anti-vibration device, which is disposed on a vibration-damping table placed on a shelf bed and is movable forward and backward in a direction crossing the workpiece,

And stopper means for restricting one end of the dust-tightening opening so that one end of the dust-removing opening is in close contact with the dust-prevention table.

Wherein the stopper means comprises: a stationary block protruded on the dustproof table;

A stopper block protruded outward at one end of the dustproof box so that one side of the dustproof box is in surface contact with the fixed block during a forward movement of the dustproof box;

And a stopper member disposed on the dustproof table and coupled to one end of the stopper member through a hinge shaft so as not to interfere with the forward and backward movement of the discharge port and to be contactable with the other surface of the stopper block during a rotation operation.

The stopper member includes a rotary shaft hinged to be rotatable at one end thereof,

And a contact hole which is engaged with the end of the rotary shaft so as to be moved forward and backward.

Preferably, the stopper means further comprises a fixing piece arranged to be spaced apart from each other to oppose each other so as to receive a part of the stopper member during a rotation operation thereof, thereby restricting movement of the stopper member.

The present invention relates to a stopper structure for a shelf vibration damping structure whose structure is improved so as to prevent backward pushing due to a shock generated during a roll seating process of a shelf springs, It is possible to prevent the backward pivoting of the vibration springs, so that it is possible to shorten the working time generated in the roll setting process and also to prevent the safety accident such as deviation from the center axis.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the structure of the stopper structure for the shelf vibration dampers according to the present invention is arranged on the bed 12 between the main shaft 20 and the tail stock 40 of the shelf 10 (30) capable of being moved forward and backward in a direction intersecting with the roll (R), which is placed on the dustproof table (35) and is movable in the lateral direction, and a discharge port And stopper means for restricting one end of the discharge port 30 in a state in which it is in close contact with the dustproof table 35 after the forward movement of the discharge port 30.

More specifically, the stopper means includes a fixing block 38 protruded on the vibration-proof table 35 and a fixing block 38 which protrudes from the fixing block 38 so that one side surface of the vibration- A stopper block 33 protruding outward at one end of the shock absorber 30 and a stopper block 33 disposed on the vibration isolating table 35 and coupled at one end thereof via a hinge shaft 215, And a stopper member (200) having a rotatable structure and capable of contacting with the other side surface of the stopper block (33) in a rotating operation.

The fixed block 38 is provided on the dustproof table 35 adjacent to the forward and backward travel path of the discharge port 30 and is structured to be fixed via a fastening member such as a bolt.

The stopper block 33 is a structure that protrudes laterally at a lower portion of one end of the body 32 of the discharge port 30 and is formed integrally with the discharge port 30 or fixed to the discharge port 30 through a fastening member such as a bolt .

The stopper member 200 is disposed on the stopper plate 110 fastened with a bolt on the dustproof table 35.

The stopper member 200 is fixed to the stopper plate 110 so as to penetrate through a hole formed in the end of the rotary shaft 210 and a rotary shaft 210 coupled to the hinge shaft 215 so that one end of the stopper shaft can rotate, , And a backwardly movable contact member (220).

The contact hole 220 has a thread formed on the outer circumferential surface at one end so as to move forward and backward by a rotating operation and a hole of the rotary hole 210 has a structure in which a female screw thread is formed on the inner circumferential surface to be fastened to the thread of the contact hole 220 .

In addition, the contact member 220 has a structure in which a handle 230 in the form of a rod is passed for rotation.

The stopper member 200 is spaced apart from the stopper plate 110 so as to restrict movement of the stopper member 200 in the forward and backward directions. And further includes a fixing piece 150 having a shape facing each other.

The operation of the present invention having such a structure will be described as follows.

The stopper structure for a shelf vibration damping tool according to the present invention has a structure in which the stopper 30 is advanced on the dustproof table 35 in order to place the workpiece R on the dustproof spout 30, The block 33 is brought into close contact with the fixed block 38 on the dustproof table 35.

When the contact hole 220 is rotated with the rotary shaft 210 rotated around the hinge shaft 215, .

As a result, one side of the stopper block 33 of the dustproof box 30 is in surface contact with one side of the fixing block 38, and the other side of the stopper block 33 is in contact with the end of the contactor 220 And functions as a stopper for preventing rearward pivoting of the discharge port (30).

At this time, the rotary shaft 210 is rotated about the hinge shaft 215 and is received between the fixing pieces 150, which are separated from each other in a part of the upper surface thereof, so that they are interfered with movement in forward and backward directions, have.

The end of the contact hole 220 is spaced apart from the other side of the stopper block 33 when the rotation hole 210 rotates and the contact hole 220 is rotated in one direction As a result, the end of the contact member 220 is brought into contact with the stopper block 33.

Therefore, even if the stopper block 33 of the dustproof box 30 is brought into close contact with the fixing block 38 at the front and with the contactor 220 in close contact with the rear of the stopper block 30, , The movement in the backward direction is restricted.
