Description

Apparatus for changing work rest shell in lathe}

The present invention relates to a shelf anti-vibration shell replacement device, and more particularly to a dust-proof shell replacement device that can be easily replaced with a small force by moving the shell mechanically using a roller and a trailer. .

In general, a lathe is a machine tool which processes a workpiece in a predetermined form by linear movement of the tool in a plane including the rotation of the workpiece and its axis of rotation.

The shelf is fixed to the working surface, the bed serves as a base and a guide, the headstock is formed on one side of the bed and rotated by the power of the motor, and slide along the guide surface of the bed and the tool is mainly fixed Tool carriages, tailstocks and attachments that hold the center of the workpiece.

In this case, the vibration isolator used as one of the attachments is a tool that prevents bending and vibration due to the workpiece when machining a long diameter diameter compared to the length. It can be divided into a moving dustproof mouth.

In particular, when machining a large workpiece of a heavy weight, such as a generator rotor, a dustproof outlet is necessary to support it.

These dust barriers require the replacement of a shell directly in contact with the workpiece when the workpiece to be machined is changed. The shell is installed on top of the quill, which can be elevated.

However, in order to replace the shell, it is very inconvenient for the worker to work between the workpiece and the narrow dust isolation.

In addition, in the case of large lathes, such as a generator rotor, the weight of the shell is only 40kg or more, causing workers to cause musculoskeletal disorders if they work repeatedly.

Therefore, the present invention has been made in order to solve the above problems, the shell is mounted on the seat of the trailer directly from the crane and push the trailer to transport the shell to the upper side of the quill shelf dustproof shell replacement device easy to work The purpose is to provide.

In addition, an object of the present invention is to provide a shelf dustproof shell replacement device that can prevent the occurrence of industrial accidents, such as musculoskeletal disorders, so that the operator does not need to lift the heavy shell.

In addition, it is an object of the present invention to provide a shelf anti-vibration shell replacement device that can be easily replaced by the shell formed on both sides of the outer ring portion of the roller to be inclined downward eccentric load.

In another aspect, the present invention is to provide a shelf anti-vibration shell replacement device that can prevent the shell from falling apart by installing a stop wave on the rim.

The present invention comprises a plurality of rollers installed in at least two stages in a horizontal direction on one side of the shelf dustproof tool; A trailer which is fitted to the plurality of rollers and moves along a horizontal direction; It provides a shelf dustproof shell replacement apparatus comprising a; seating portion installed on the top of the trailer.

Here, the plurality of roller outer ring portions are formed to be inclined downward to both sides with respect to the center, and the trailer is preferably formed with a guide groove corresponding to the outer ring portion.

In addition, the seating portion is preferably a stop wave formed on the rim.

Shelf anti-vibration shell shell replacement device according to the present invention as described above is easy to work because the shell is seated on the seat of the trailer directly from the crane and pushing the trailer to transfer the shell to the upper side of the quill.

In addition, the shelf dustproof shell shell replacement apparatus according to the present invention can prevent the occurrence of industrial disasters, such as musculoskeletal disorders by eliminating the need for the operator to lift the heavy shell.

In addition, the shell dustproof shell shell replacement apparatus according to the present invention is formed to be inclined downward on both sides of the outer ring portion of the roller can be easily replaced shell even under the action of the eccentric load.

In addition, the shelf dustproof shell shell replacement apparatus according to the present invention can prevent the shell from falling off by installing a stop wave on the rim.

1 is a front view showing a dustproof hole is installed shell replacement apparatus according to an embodiment of the present invention.
Figure 2 is a side view showing a dustproof port is installed shell replacement apparatus according to an embodiment of the present invention.
Figure 3 is a detail main cross-sectional view showing a dustproof port is installed shell replacement apparatus according to an embodiment of the present invention.
4A to 4C are operation state diagrams sequentially showing the operation of the shell replacement apparatus according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the shelf dustproof shell shell replacement apparatus according to an embodiment of the present invention.

Shelf dustproof shell shell replacement apparatus according to an embodiment of the present invention is a plurality of rollers 20 installed on one side of the shelf dustproof outlet 10, as shown in Figures 1 to 3, and the plurality of rollers 20 The trailer 30 is inserted into and moved, and the seating portion 40 installed on the upper portion of the trailer (30).

The roller 20 is installed in two stages in the horizontal direction on one side of the dustproof opening 10 located below the roll (R). Here, the outer ring portion 22 of the roller 20 extends inclined downward to both sides with respect to the center of the roller 20. The roller 20 corresponds to the guide groove 32 of the trailer 30, and the trailer 30, which is in contact with the roller 20, moves as the roller 20 rotates. The roller 20 is installed to extend to the side of the quill 24 to maintain the gap between the shell 50 and the roll (R) while lifting.

The trailer 30 is fitted to the roller 20 and moves along the horizontal direction. The trailer 30 has a guide groove 32 in contact with the outer ring portion 22 of the roller 20 has a 'V' shape corresponding to the outer ring portion 22 of the roller 20. In addition, the trailer 30 has a seating groove 34 for mounting the seating portion 40 on the upper side. In addition, the trailer 30 is fixed by the seating portion 40 and the bolt 36.

The seating portion 40 is formed on the upper portion of the trailer 20, it is preferable that the seating surface 42 is beautifully processed to facilitate the sliding of the shell 50. The seating portion 40 has a seating protrusion 44 fitted into the seating groove 34 of the trailer 30. The seating portion 40 is provided with a stop wave 46 to prevent the shell 50, which is seated on the seating surface 42 on the rim fall. The seating portion 40 is formed with a reinforcement beam 48 to prevent the seating portion 40 from bending.

Hereinafter, the operation of the shelf dustproof shell shell replacement apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, the shell 50 is mounted on the seating surface 42 of the seating part 40 exposed outside the working radius of the roll R using a crane as shown in FIG. 4A.

Next, after confirming that the shell 50 is seated on the seating surface 42, the operator pushes the trailer 30 to the installation position of the shell 50 as shown in FIG. 4B. At this time, the roller 20 can be easily moved even with a small force because the rolling contact with the trailer (30).

Next, when the trailer 30 moves to the installation position of the shell 50, the worker pushes the shell 50 to the upper surface of the quill 24 to move it. In this case, even if the weight of the shell 50 is 40kg or more, the seating surface 42 may be beautifully processed to move the shell 50 to the upper surface of the quill 24 without applying a large force.

Next, the quill 24 is raised using the lifting means so that the shell 50 faces the roll R at a preset position as shown in FIG. 4B. At the same time, the trailer 30 is moved outside the rotation radius of the roll (R) for safety and starts processing.
