BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic apparatus for a passive shelf,

The present invention relates to an automation apparatus for a passive-type lathe and a control method thereof, and more particularly, to an automation apparatus for a passive-type lathe that can be mounted on any passive-type lathe,

In general, a lathe refers to a typical machining equipment that causes machining to occur by contacting a machining tool while the workpiece is rotated. Such a lathe can be divided into a passive type lathe in which a worker directly manipulates the processing tool in a state in which the workpiece is rotated while the workpiece is rotated, and an automatic lathe in which the processing tool moves automatically and a machining operation occurs.

FIG. 1 schematically shows an example of a conventional automatic lathe. In general, an automatic lathe in which a final product is manufactured by simply inputting numerical information by a worker is widely recognized for its convenience.

However, when a relatively complicated shape is finely processed to produce a small quantity of products of various kinds, it is more appropriate to use a passive type lathe, but the existing automatic lathe is unified and can not be used as a passive lathe.

In addition, when a company having a passive shelf wants to plan mass production of a small product due to a product design change, there is a problem in that an automatic shelf is newly purchased, but the passive shelf is left untreated, thereby increasing the production cost as a whole.

An object of the present invention is to solve such conventional problems, and it is an object of the present invention to provide an automation apparatus for a passive lathe, which can be used as an automatic lathe by automating the lathe by way of mounting on a passive lathe, And a control method.

In addition, the control section controls the machining step of moving the machining section along the X axis in a state that the machining section is moved at a predetermined distance along the Y axis so that the machining step is repeated a plurality of times.

The control unit may further include: a storage module that stores final shape information of the workpiece and workpiece information of the workpiece; And a calculation module for calculating movement information of the moving part using the information stored in the storage module.

In addition, the calculation module can determine the amount of processing and the number of repetition of processing per one time in consideration of the material characteristics of the work.

In addition, the calculation module can reduce the amount of processing per one cycle, and increase the number of repetitions of the process, as the hardness of the workpiece increases.

The above object can also be achieved according to the present invention by an initialization step of moving the processing part to an initial position; A calculating step of calculating movement information of the moving part by converting the preset data based on the initial position so as to be applicable to the passive lathe; And a machining step of moving the moving part by using the movement information calculated in the calculating step while the workpiece is rotating to machine the workpiece. .

Further, in the initialization step, the position of the machining portion in a state in which the interval from the automation device has reached a preset value can be set as an initial position.

In addition, the Y-axis moving step and the X-axis moving step may be repeated a plurality of times so that the workpiece is processed to a predetermined machining depth.

In the calculating step, the amount of movement of the machining portion and the number of repetitions of the machining step in the Y-axis moving step can be determined in consideration of the material characteristics of the workpiece.

Further, in the calculating step, as the hardness of the workpiece is increased, the amount of movement of the machining portion in the Y-axis moving step can be decreased, but the number of repetitions of the machining step can be increased.

According to the present invention, there is provided an automation apparatus for a passive-type lathe and a control method thereof, which can be applied to various passive-type lathes regardless of the type of a maker or a model to automate processing.

The driving module 143 is a module for moving the moving unit 120 based on the moving information calculated by the calculating module 142.

The above-described processing method using the control unit will be described later.

Hereinafter, a control method (SlOO) of the automatic apparatus for a passive lathe according to an embodiment of the present invention will be described in detail.

4 is a flowchart of a method of controlling an automation apparatus for a passive lathe according to an embodiment of the present invention.

As shown in Fig. 4, the control method S100 of the automation apparatus for a passive lathe in this embodiment includes an initializing step S110, a calculating step S120, and a machining step S130.

Fig. 5 conceptually shows a process of initializing the control method of the automation apparatus for passive lathe in Fig.

5, the initialization step (S110) is the first step performed in a state in which the passive lathe 50 is disposed adjacent to the automation apparatus 100 for a passive lathe in the first embodiment, and a full-scale processing step Is a step for initializing the position of the processing unit 110 before execution.

That is, in this step, by setting the initial position of the machining unit 110 in consideration of the shape and size of the passive type shelf 50, the present invention can be applied to all passive type shelves 50, So that it can be used as a general purpose.

The first position adjusting unit 122 moves the machining unit 110 on the Y axis and the first measuring member 131 measures the gap between the machining unit 110 and the passive shelf 50 in real time do. At the same time, when it is determined that the interval between the machined portion 110 and the passive lathe 50 on the Y axis has reached the preset value dy stored in the storage module, the driving of the first position adjuster 122 is stopped do.

The second position adjusting unit 123 moves the machining unit 110 on the X axis and the second measuring member 132 measures the gap between the machining unit 110 and the passive shelf 50 in real time do. At the same time, if it is determined that the interval between the machined portion 110 and the passive shelf 50 on the X axis reaches the preset value dx stored in the storage module 141, The driving is stopped.

On the other hand, in the present embodiment, the reference point for measuring the interval on the Y axis is set to the rotation axis 51 of the passive type lathe 50, the reference point for measuring the interval on the X axis is the side portion of the processing tool 112, But is not limited to.

The position of the machining portion is set to the initial position in the state where the driving of the first position adjusting portion 122 and the second position adjusting portion 123 is stopped, that is, the state where the movement is stopped, and is stored in the storage module 141 .

Therefore, in this step, the interval between the passive shelf 50 and the machining unit 110 is preset and the initial position (coordinate) is initialized based on the preset interval information. Therefore, in the calculating step described later, The passive lathe can be automated by calculating data based on the coordinates, and the detailed machining process will be described later.

According to the above description, the initial position of the Y-axis and the initial position of the X-axis are set in order, but the order of setting the initial position is not limited to the above-mentioned contents, and the initial position of the Y- And the driving of the moving part 120 for judgment may be performed at the same time.

The calculating step S120 is a step of acquiring movement information for moving the moving part 120 by converting the machining information stored in the storage module S110 on the basis of the initial position. The first step S121 and the second Step S122.

The first step S121 is a step of determining a movement amount or a relative coordinate value to which the moving unit 120 should move based on the initial position. In other words, in this step, the movement amount to which the moving unit 120 is moved is calculated using the initial position determined by the passive lathe 50 as the reference coordinates.

The second step S122 is a step of calculating the final movement information of the moving unit by dividing the movement amount determined in the first step S121 into several steps.

That is, even when the workpieces are processed into the same shape, the number of machining operations is adjusted based on the characteristics of the workpieces T so that smooth and detailed machining can be performed. For example, even when the workpiece is to be machined to a predetermined machining depth, the movement information is calculated so that the machining amount per workpiece is reduced as the hardness of the workpiece is increased, but the number of repetitions of machining is increased.

Fig. 6 is a view for explaining the processing steps of the control method of the automation apparatus for the passive lathe of Fig.

As shown in FIG. 6, the machining step S130 is a step of machining the actual workpiece T based on the movement information obtained in the calculating step S120.

That is, in a state in which the workpiece T is rotating on the passive type lathe, the second position adjusting part 123 is moved in the Y-axis direction by using the first position adjusting part 122, The workpiece T is machined by moving the machining portion 110 along the X axis. At this time, the workpiece T can be processed to the final machining depth by repeating the above steps according to the movement information obtained in the calculation step S120.

For the sake of understanding, this processing method will be described below as a concrete example.

[Example]

For a more detailed description, it is assumed that the workpiece T is to be machined to a predetermined machining depth d, for example.

If the initial position of the machining unit 110 is determined in the initializing step S110, the final movement information is calculated using the information stored in the storage module 141 in the calculating step S120.

Specifically, in the first step S121, the calculation module 142 determines the movement amount of the machining portion 110 in the Y-axis direction and the movement amount in the X-axis direction based on the initial position. Assume that the amount of movement of the machined portion 110 on the Y-axis is d and the amount of movement in the X-axis direction is determined as w.

In the second step S122, the calculation module 142 determines the movement amount of the machining portion 110 in the Y-axis direction, that is, the machining amount per one cycle and the repetition frequency of machining, according to the characteristics of the workpiece T, Assuming that the workpiece is made of a hard material, that is, the hardness is high, the amount of movement of the machining portion 110 in the Y-axis direction once is d / n, and the process of machining to a depth of d / The movement information of the moving part 110 is calculated.

In the machining step (S130), the actual machining proceeds based on the movement information secured by the calculation module (142). That is, in a state in which the workpiece T is rotating, the driving module 143 operates the first position adjusting portion 122 to advance the machining portion 110 by d / n in the Y-axis direction, The control unit 123 is operated to move the machining unit 110 along the X-axis direction by w so that the workpiece is machined to a depth of d / n. The workpiece is machined to a predetermined machining depth d by moving the machining portion 110 at the same numerical value n total times.

However, if the finished shape of the workpiece is complicated, the above-described process is repeated step by step according to the shape. For example, in the case of machining a shape having N steps, the above process is performed N times.

FIG. 7 is a conceptual diagram for explaining a case where a control method of a passive lathe automatic apparatus of FIG. 4 is applied to a work having a complicated shape. In the case of FIG. 7, the value of N becomes 3, Step is performed.

On the other hand, it is preferable that the number of repetition of the machining step (n) is reduced since the durability of the workpiece decreases as each step increases and the outer diameter of the workpiece decreases.

Therefore, according to the present invention, it is possible to automate processing by applying it to various kinds of passive type lathe in general. In addition, by adjusting the machining method in consideration of the material of the work, more smooth machining can be achieved.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
