Description

Driven tool mounting mechanism and driven tool mounting method using the same {DRIVEN TOOL MOUNTING DEVICE AND METHOD FOR DRIVEN TOOL MOUNTING USING THE DRIVEN TOOL MOUNTING DEVICE}

The present invention relates to a driven tool mounting mechanism and a driven tool mounting method using the same. A driven tool mounting mechanism that allows the coupling to be fastened at an angle aligned with the driven tool in a state in which the work tool is assembled to the tool, and by using the driven tool mounting mechanism to mount the driven tool to the turret, It relates to a driven tool mounting mechanism capable of replacing a tool and a driven tool mounting method using the same.

In general, a computerized numerical control (CNC) among machine tools that processes a workpiece is a spindle unit in which an axis is interlocked with a spindle motor and a chuck capable of clamping a workpiece is inserted into the axis, and a workpiece is rotated at high speed. A tailstock unit positioned on the same centerline as the drive shaft of the spindle unit to support the center of the workpiece to prevent it from being off center by centrifugal force, and a ball screw installed on a bed above the spindle unit and performing horizontal and vertical movements It consists of a unit and a tool rest installed on the upper part of the transfer table of the ball screw unit and equipped with various tools so that turning, milling, and drilling operations can be performed by approaching the workpiece.

This tool post has a turret type that is radially provided on the outside of the turret to process the workpiece by division rotation according to the desired processing, and the tool is provided in a straight line to perform the desired processing by upward and downward movement (gang) gang) type.

The turret device used in the turret-type tool post radially mounts several types of cutting tools around the rotary cutting tool post called the turret, and each time the turret is rotated, each cutting tool comes into position in turn along the cutting part, thereby providing various Even a workpiece requiring a process can be completed by rotating the turret.

On the other hand, a numerically controlled lathe (CNC) in which a workpiece to be processed rotates and a tool mounted on a transfer table moves while processing is called a turning center. A turning center consists of various parts, such as a sub-spindle machine for double-sided machining and a driven tool holder combined with a driven tool.

Recently, due to the demand for complex processing of turning centers, the installation of driven tools is widely used to enable milling as well as turning, and drill or end mill tools are usually replaced while the driven tool holder is mounted on the turret. At this time, the collet nut is loosened or tightened by holding a spanner and a wrench in both hands. If the spanner and wrench are not used at the same time, a malfunction may occur, causing inconvenience such as unstable posture of the operator.

In order to improve this, a spanner or wrench (hereinafter, referred to as a 'one-handed work tool') specially manufactured for the driven tool is used so that the operator can perform the work with one hand. However, in the case of a turret-type tool post in which a driven tool is fixed in a specific direction (hereinafter referred to as an 'orient index type tool post'), the spindle of the driven tool does not rotate as the direction of the driven tool is fixed. There is a problem that the use of a 'one-handed work tool' is impossible.

Therefore, even in the case of an 'orient index type tool post', there is a need for a technology in which an operator can conveniently perform work by using a 'one-handed work tool'.

The matters described as the background art above are only for improving understanding of the background of the present invention, and should not be taken as an admission that they correspond to prior art already known to those skilled in the art.

1 is a view showing a driven tool mounting mechanism according to an embodiment of the present invention.

Referring to FIG. 1, the driven tool mounting mechanism according to the present invention is connected to a body portion 100 having a through hole 110 through which a driven tool 300 is mounted, and the outside of the body portion 100, It is connected to the opposite side of the direction in which the driven tool 300 is mounted and includes a coupling guide 200 formed with a gripping portion 210 for gripping the coupling 400 fastened to the driven tool 300, the driven tool The coupling 400 is aligned with the driven tool 300 by rotating the coupling guide 200 in a state where the 300 is mounted in the through hole 110 and the coupling 400 is gripped by the gripping part 210 It can be fastened at an angle.

That is, the driven tool mounting mechanism according to the present invention is composed of the body portion 100 and the coupling guide 200, and the through hole 110 through which the driven tool 300 is mounted is formed in the body portion 100 And, a gripping portion 210 for gripping the coupling 400 is formed in the coupling guide 200. At this time, the gripping part 210 has a groove formed in the direction toward the inside of the coupling guide 200, an open part is formed on the outside and closed on the inside, so that the coupling 400 is broken through the open part. By being inserted into the branch 210, the coupling 400 can be gripped.

In addition, the coupling guide 200 is rotatably coupled to the body portion 100, and the coupling guide 200 may be rotated so that the opening portion of the gripping portion 210 is positioned upward or sideways. Accordingly, the angle of the coupling 400 can be adjusted as the coupling guide 200 is rotated while the coupling 400 is gripped by the gripping portion 210 .

Eventually, the driven tool 300 is mounted through the through hole 110 of the body 100, and the coupling guide 200 is rotated while the coupling 400 is gripped by the gripping portion 210. By doing so, it is possible to ensure that the coupling 400 is fastened at an angle aligned with the driven tool 300.

At this time, the reason for fastening the coupling 400 at an angle aligned with the driven tool 300 will be described in detail below with reference to FIGS. 4 to 8 .

4 is a view showing that the driven tool 300 is inserted and mounted into the insertion part 510 of the turret 500 in a state of being coupled with the coupling 400, and FIG. 5 is an orient index method tool post 600 6 is a view showing that the drive shaft control unit 610 of the orient index type tool post 600 is in a normal state, and FIG. 7 is a view showing a one-handed work tool 700 in the form of a wrench, 8 is a view showing a state in which the work tool 700 of FIG. 7 is assembled and fixed to the driven tool 300.

As described above, a turning center has a tool post equipped with various tools for turning, milling, and drilling as a component, and these tool posts are classified into a turret type and a gang type. The driven tool mounting mechanism according to the present invention is applied to a turning center using a turret type tool post, and the driven tool 300 and the coupling 400 are fastened by the driven tool mounting mechanism, and the coupling 400 The fastened driven tool 300 is inserted and mounted into the turret 500.

Referring to FIG. 4 , an insertion portion 310 into which a driven tool 300 is inserted is formed in the turret 500, and a coupling 400 fastened to the driven tool 300 is inserted into the insertion portion 310 and the driven tool. It can be seen that the driven tool 300 to which the coupling 400 is fastened is mounted to the turret 500 while being located between the turrets 300.

At this time, in the case of the 'orient index type tool post 600', as the direction of the driven tool 300 is fixed, in a state where the driven tool 300 is mounted on the turret 500, the spindle 360 of the driven tool 300 ) is not rotated, so the use of the 'one-handed work tool 700' is impossible.

5 shows an orient index type tool post 600, and a drive shaft receiving power from the driven tool 300 is formed therein. In such an orient index type tool post 600, in the process of inserting the driven tool 300 into the turret 500, the coupling 400 fastened to the driven tool 300 collides with the drive shaft inside the turret 500. In order to prevent this, an adjustment unit capable of adjusting the direction of the drive shaft is formed.

Specifically, as shown in FIG. 6, the driven tool 300 is finally inserted into the turret insertion part 510 in a state where the drive shaft control unit 610 is adjusted vertically and is formed vertically with respect to the bottom surface of the tool rest. ), and this state is called a steady state. On the other hand, as shown in FIG. 5 , the driven tool 300 is not properly inserted into the insertion part 510 of the turret when the control part of the drive shaft is displaced from the normal state.

In addition, even if the direction of the drive shaft corresponds to the normal state, the direction of the coupling 400 fastened to the driven tool 300 may be turned or twisted due to minute vibration or vibration when the driven tool 300 is inserted. In this case, the driven tool 300 is not properly inserted into the insertion part 510 of the turret.

That is, there is a need to fix the direction or position of the coupling 400 fastened to the driven tool 300, and for this, the coupling 400 is fastened and fixed at an angle aligned with the driven tool 300.

Furthermore, a guide ring for fixing the direction or position of the coupling 400 is installed in the driven tool 300, and this guide ring limits the rotation of the spindle 360. That is, in a state where the driven tool 300 is mounted on the turret 500, the rotation of the spindle 360 becomes impossible.

7 shows a one-handed work tool 700 in the form of a wrench as an example, and this one-handed work tool 700 may be manufactured and used in the form of a spanner. Referring to FIG. 8 by taking the one-handed work tool 700 in the form of a wrench shown in FIG. 7 as an example, the one-handed work tool 700 is assembled to the coupling pin 350 and the engaging groove formed in the spindle 360 ( The end 710 of the one-hand working tool 700 is hooked to 361 and fixed. At this time, rotation of the spindle 360 is required to engage the end 710 of the one-hand working tool 700 in the locking groove 361 . Therefore, in a state where the driven tool 300 is mounted on the turret 500, the operator cannot use the one-handed work tool 700.

In order to solve this problem, in the driven tool mounting mechanism according to the present invention, in a state in which the one-hand work tool 700 is first assembled and fixed to the driven tool 300, the coupling 400 is connected to the driven tool 300. By fastening at an aligned angle, a state in which the one-handed work tool 700 can be normally inserted into the orient index type tool post 600 while maintaining a fixed state to the driven tool 300 is to be formed. By mounting the driven tool 300 in this state to the turret 500, even in the case of the orient index type tool rest 600, the driven tool 300 is mounted on the turret 500, and the one-handed work tool ( 700) can be used to replace the tool of the turning center.

Meanwhile, in order to help understand the present invention, the coupling 400 fastened to the driven tool 300 will be additionally reviewed.

Coupling 400 is a part for the purpose of transmitting torque on the driving side by connecting two different rotating bodies (eg, a motor shaft and a ball screw), and misalignment (eccentricity, deflection, end play, etc.) to reduce assembly and adjustment loads. Furthermore, by destroying the coupling 400 and releasing the connection between the rotating bodies when an unexpected overload occurs, the expensive power unit and the entire device can be protected.

For reference, here, declination and eccentricity are angular errors of two axes connected by the coupling 400, declination refers to angular errors of both axis centers, and eccentric refers to parallel errors of axis centers. End play is the amount of displacement in each axial direction, and occurs when the motor expands when the temperature rises due to long-time use or when the motor accelerates or decelerates. Such misalignment causes vibration, noise, and excessive load on related mechanical elements. That is, the coupling 400 plays a role of absorbing such a load, so that the driven tool 300 is stably coupled to the turret 500 so that it can be driven.

On the other hand, the body portion 100 of the driven tool mounting mechanism according to the present invention includes a main body 120 in which a through hole 110 is formed and a sub body connecting the main body 120 and the coupling guide 200 ( 150).

A through hole 110 is formed in the main body 120, and the driven tool 300 is mounted through the through hole 110, and the sub body 150 connects the main body 120 and the coupling guide 200. In addition to connection, the position of the coupling guide 200 is determined so that the coupling 400 can be fastened at an angle aligned with the driven tool 300 mounted through the through hole 110.

Furthermore, by gripping and pulling the subbody 150, the user can easily separate the driven tool 300 to which the coupling 400 has been fastened and the driven tool mounting mechanism according to the present invention can be easily separated. That is, only the driven tool 300 to which the coupling 400 is fastened can be mounted on the turret 500, excluding the driven tool mounting mechanism.

At this time, the subbody 150 can be replaced with parts of various types and materials such as wires, as long as the coupling 400 can be fastened at an angle aligned with the driven tool 300, and must necessarily be shown in FIG. As shown, it does not have to be configured only in a plate shape. Hereinafter, the plate-shaped subbody 150 shown in FIG. 1 will be described as an example to aid understanding of the present invention, and the content of the present invention should not be construed as being limited due to this example.

Referring to FIG. 1, the main body 120 of the driven tool mounting mechanism according to the present invention is provided at one end of the sub body 150 at a right angle to the sub body 150, and the other end of the sub body 150. The coupling guide 200 may be coupled to be rotatable.

That is, by providing the main body 120 and the coupling guide 200 at both ends of the sub body 150, it is aligned with the driven tool 300 mounted through the through hole 110 of the main body 120. The position of the coupling guide 200 can be determined so that the coupling 400 can be fastened at an angle.

In addition, the coupling guide 200 is rotatably coupled to the sub body 150, so that an angle at which the coupling 400 is coupled with the driven tool 300 can be adjusted. At this time, it is preferable that the coupling part 151 of the coupling guide 200 and the sub body 150 is formed by a hinge coupling. However, as long as the coupling 400 can be fastened at an angle aligned with the driven tool 300, it is not necessarily formed as a hinged coupling, and the contents of the present invention should not be considered to be limited by this description.

2 is a view showing a state in which the driven tool 300 and the coupling 400 are coupled.

1 and 2, the main body 120 of the body 100 of the driven tool mounting mechanism according to the present invention has a through hole 110 formed in the center, and a direction in which the driven tool 300 is mounted. In the cross section of, one side is connected to the through hole 110 and the other side has a first fixing groove 130 formed with an opening to the outside of the main body 120 and a second fixing spaced apart from the through hole 110. A groove 140 is formed, and the driven tool 300 has an insertion portion 310 passing through the through hole 110, and a first protrusion 330 protruding in the direction in which the insertion portion 310 is inserted, and The second protrusion 340 is formed, the first protrusion 330 is inserted into the first fixing groove 130, and the second protrusion 340 is inserted into the second fixing groove 140, so that the driven tool 300 is formed. It may be mounted in the through hole 110 .

Each of the fixing grooves 130 and 140 and the respective protrusions 330 and 340 corresponding thereto allow the driven tool 300 and the driven tool mounting mechanism to be stably mounted by inserting the protrusions into the fixing grooves. Specifically, since the first fixing groove 130 is connected to the through hole 110 and formed, minute details that may occur when the insertion part 310 of the driven tool 300 penetrates the through hole 110 and is inserted. Absorb vibrations or vibrations.

That is, the coupling 400 is fastened to the end of the insertion part 310 of the driven tool 300. When the driven tool 300 is inserted into the insertion part 510 of the turret, the driven The direction of the coupling 400 fastened to the end of the insertion part 310 of the tool 300 may be turned or twisted. In this case, since the driven tool 300 is not properly inserted into the insertion part 510 of the turret, the first fixing groove 130 is formed in the driven tool mounting mechanism according to the present invention to insert the driven tool 300 into the first By combining with the protruding part 330, vibration of the insertion part 310 of the driven tool 300 is absorbed and the direction of the coupling 400 fastened to the driven tool 300 is prevented from being misaligned. In addition, it is natural that the first fixing groove 130 has an effect of allowing the operator to find an appropriate position for the insertion part 310 of the driven tool 300 by forming an open portion outside the main body 120.

In addition, in the case of the second fixing groove 140, it is arranged spaced apart from the outside of the through hole 110 and coupled with the second protrusion 340 of the driven tool 300, so that the driven tool 300 according to the present invention is driven. It stably fixes the state mounted on the tool mounting mechanism. That is, when the driven tool 300 is inserted into the driven tool mounting mechanism according to the present invention, after adjusting the appropriate position of the driven tool 300 insertion part 310 through the first fixing groove 130, the corresponding position Mounting of the driven tool 300 by inserting the second protrusion 340 of the driven tool 300 into the second fixing groove 140 so that the driven tool 300 can be fixed with the driven tool mounting mechanism according to the present invention. is to complete

Furthermore, each of the fixing grooves 130 and 140 and each of the protrusions 330 and 340 corresponding thereto may be formed in plurality, and it is driven to arrange the plurality of fixing grooves and the protrusions at equal intervals from each other. It is preferable in terms of enabling the tool 300 to be stably mounted and fixed to the driven tool mounting mechanism according to the present invention.

On the other hand, the driven tool 300 mounted on the driven tool mounting mechanism according to the present invention is composed of a spindle 360 constituting a rotation axis and a fixing part 320 provided inside the spindle 360, and the spindle 360 is When the driven tool 300 is used, it may include a head portion exposed to the outside and an insertion portion 310 extending from the head portion and penetrating the through hole 110 .

Here, the spindle 360 constitutes a rotational axis of the driven tool 300, and serves to transmit driving force to the drive shaft inside the turret 500. A fixing part 320 is provided inside the spindle 360, and a collet nut is generally used for the fixing part 320. That is, by loosening or tightening the collet nut, the driven tool 300 can be mounted on or off the turret 500.

And, here, 'when using the driven tool 300' refers to the case where the driven tool 300 is mounted on the turret 500 and used, and at this time, the insertion part 310 of the spindle 360 of the driven tool 300 is Since the driving force is transmitted to the drive shaft inside the turret 500 through the coupling 400, it is not observed from the outside. On the other hand, the head of the spindle 360 of the driven tool 300 is exposed to the outside together with the fixing part 320 inside the spindle 360, and when the operator replaces the tool of the turning center, the driven tool is removed from the turret 500. There is an effect of being able to perform the replacement work by contacting the work tool 700 to the spindle 360 or the fixing part 320 exposed to the outside without releasing the mounting of the 300 .

3 is a development view when the coupling 400 is coupled to the driven tool 300 through the coupling guide 200 of the driven tool mounting mechanism according to an embodiment of the present invention.

Referring to FIG. 3, at the end of the insertion part 310 of the driven tool 300 mounted on the driven tool mounting mechanism according to the present invention, a fastening part 311 to which the coupling 400 is fastened is provided, and the fastening part An angle at which the coupling 400 is fastened can be maintained constant by the angle 311 .

In general, the coupling 400 has a configuration such as a fixing key 410 therein, so that the coupling 400 can be fixed without twisting the coupling angle in a state in which the coupling 400 is coupled to the driven tool 300. Therefore, at the end of the insertion part 310 of the driven tool 300 mounted on the driven tool 300 mounting mechanism according to the present invention, a fastening part 311 to which the above fixing pin 410 can be fastened is separately formed. .

Accordingly, when the driven tool 300 is mounted on the orient index type tool post 600, it is possible to prevent a collision between the drive shaft and the coupling 400 inside the turret 500.

For reference, the fastening part 311 as above may be formed in the same configuration as the aforementioned guide ring. However, this is only an example to aid understanding of the present invention, and the content of the present invention should not be construed as being limited by these examples.

As seen above, a fastening part 311 for fixing the direction or position of the coupling 400 is installed in the driven tool 300, and this fastening part 311 limits the rotation of the spindle 360. do. That is, in a state where the driven tool 300 is mounted on the turret 500, the rotation of the spindle 360 is impossible.

Therefore, the driven tool 300 mounted on the driven tool mounting mechanism according to the present invention needs to be assembled with the working tool 700 before the coupling 400 is fastened. That is, after the driven tool 300 is mounted on the driven tool mounting mechanism, the work tool 700 must be assembled in advance before the coupling 400 is fastened.

Then, in a state where the coupling 400 is coupled to the gripping part 210 of the coupling guide 200, the coupling guide 200 is rotated to bring the coupling 400 closer to the driven tool 300, By fastening the coupling 400 whose direction is fixed by the gripper 210 to the driven tool 300, the coupling 400 can be fastened at an angle aligned with the driven tool 300.

Meanwhile, in the method of mounting the driven tool 300 using the driven tool mounting mechanism according to the present invention, after the step of inserting and mounting the driven tool 300 into the through hole 110 of the body 100, the work tool ( 700) is assembled to the coupling pin 350 of the driven tool 300 and the spindle 360 is rotated so that the end 710 of the working tool 700 is driven into the engaging groove 361 of the spindle 360 of the driven tool 300.
