Description

Vertical machining center{VERTICAL TYPE MACHINING CENTER}

The present invention relates to a vertical machining center, and more particularly, to a vertical machining center capable of performing an operation of rotating a workpiece and machining by fixing a workpiece.

In general, a machining center is a machine tool or processing device that processes a workpiece on a lathe, milling, drilling, or boring machine. Machining centers are divided into vertical machining centers in which a main shaft is mounted vertically, and horizontal machining centers in which a main shaft is mounted horizontally.

The vertical machining center is composed of a bed, a table installed on the upper part of the bed to place a workpiece, a column vertically mounted at the rear of the bed, and a spindle mounted on the column. The spindle is equipped with a tool for processing the workpiece. Accordingly, the workpiece mounted on the table can be processed while moving the spindle on which the tool is installed in the horizontal and vertical directions.

The conventional vertical machining center has a function of automatically changing a tool and a function of cutting or dividing two or more surfaces of a workpiece. However, the work of rotating the work piece and the work of machining while the work piece is fixed cannot be performed with one device. Accordingly, a device for processing while rotating the workpiece and a device for processing by fixing the workpiece were separately provided.

Since the work is performed by two separate devices, the work of transporting the workpiece from one device to another may be additionally performed. Therefore, the efficiency of the work of processing the workpiece may be lowered.

In addition, an operation of aligning the positions of the workpieces transported from different devices may be additionally performed, and the positions at which the workpieces are seated in the two devices may be different from each other. Accordingly, there may be a problem that the working time is delayed or the processing precision is lowered.

The spindle assembly 220 is connected to the first guide. The spindle assembly 220 is supported in front of the column 210 and can be moved by guides from the upper side of the table 120. The spindle assembly 220 may include a spindle 221 and a tool 220.

The spindle 221 is supported by the first guide. A tool 220 may be mounted on the spindle 221. For example, the spindle 221 may be formed in the form of a chuck capable of clamping the tool 220. The spindle 221 may rotate at high speed. Accordingly, while the tool 220 is rotated by the spindle 221, the workpiece M can be processed.

In addition, one or more spindle assemblies 220 may be provided. When a plurality of spindle assemblies 220 are provided, a plurality of workpieces M may be simultaneously processed. In this case, the table 120 may be provided as many as the number of spindle assemblies 220 are provided.

The rotating part 300 is connected to the support part 100. The rotating part 300 may rotate the table 120 provided in the support part 100. When the rotating part 300 rotates the table 120, the workpiece M on the table 120 may also rotate. Accordingly, it is possible to perform an operation of processing the workpiece (M) while rotating the workpiece (M). The rotating part 300 includes a rotating member 310, a power member 320, and a power transmission member 330.

The rotating member 310 may extend in the vertical direction. The rotating member 310 may be formed in a cylindrical shape or a shaft shape. The rotating member 310 may be located in the inner space of the bed 110, and the upper end of the rotating member 310 may be connected to the lower portion of the table 120. The center of the table 120 and the rotating member 310 may be positioned on the same line in the vertical direction. The rotating member 310 may be rotatably supported. Accordingly, when the rotating member 310 is rotated, the table 120 connected to the rotating member 310 may also be rotated.

In addition, a bearing 311 may be installed on the rotating member 310. The bearing 311 may be installed to surround the rotating member 310. An angular contact ball bearing may be used as the bearing 311. The bearing 311 can withstand both a radial load and an axial load through an asymmetric race in which the bearing balls are arranged at an angle. Thus, while the rotating member 310 withstands the load of the table 120, it is possible to stably rotate the table 120.

The power member 320 may generate power to rotate the rotating member 310. The power member 320 may be disposed inside or outside the bed 110. For example, the power member 320 may be a motor. Accordingly, the power member 320 may generate a rotational force.

In addition, the rotating member 310 may further include a support 325 for supporting the power member 320 and a case 326 installed to cover the outside of the power member 320. The support 325 may be installed on the floor of the workplace, and the height at which the rotating member 310 is disposed so as to face the rotating member 310 of the rotating member 310 may be adjusted. The case 326 may have an inner space and the lower part may be opened. The case 326 may be installed on the support 325 to accommodate the power member 320 in the inner space.

The power transmission member 330 serves to connect the power member 320 and the rotation member 310. Accordingly, the power generated by the power member 320 may be transmitted by the power transmission member 330 to the rotating member 310. Accordingly, the table 120 can be rotated by rotating the rotating member 310 with the rotational force generated by the power member 320. The power transmission member 330 includes a first rotation body 331, a second rotation body 332, and a belt 333.

The first rotating body 331 may be formed in a circular plate shape. The first rotating body 331 is connected to the lower end of the rotating member 310. The centers of the rotating member 310 and the first rotating body 331 may be positioned on the same line in the vertical direction. The first rotating body 331 may rotate together with the rotating member 310.

The second rotating body 332 may be formed in a circular plate shape. The second rotating body 332 may be connected to the lower end of the drive shaft 321 provided in the power member 320. The center of the driving shaft 321 and the second rotating body 332 may be located on the same line in the vertical direction. The second rotating body 332 may rotate together with the drive shaft 321.

In addition, the first rotating body 331 and the second rotating body 332 may be spaced apart from each other in the horizontal direction. At least a portion of the first rotation body 331 and the second rotation shaft 332 may be positioned at the same height and may be disposed to face each other.

The belt 333 may be installed to wind the first and second rotors 331 and 332. The belt 333 may be formed in a belt shape. The belt 333 may rotate together with the second rotating body 332 and may rotate the first rotating body 331. Accordingly, when the second rotating body 332 rotates, the first rotating body 331 may be rotated by the belt 333. Accordingly, the belt 333 may transmit the rotational force of the power member 320 to the table 120 to rotate the table 120.

In addition, the belt 333 may be deformed or have elasticity. Accordingly, even if the positions of the rotating member 310 and the first rotating body 331 are changed due to the operation of the fixing part 400, the belt 333 may be deformed to prevent damage to the device.

Meanwhile, an insertion groove into which the belt 333 may be inserted may be formed around the first and second rotation bodies 331 and 332. Accordingly, it is possible to suppress or prevent the belt 333 from leaving the first or second rotating body 331 or 332. Therefore, the belt 333 may stably transmit the rotational force of the power member 320 to the rotating member 310.

2 is a view showing an operation structure of a fixing unit according to an embodiment of the present invention, FIG. 3 is a plan view showing a structure of a pad according to an embodiment of the present invention, and FIG. 4 is a pusher member according to an embodiment of the present invention It is a plan view showing the operating structure of the and contact body. Hereinafter, a fixing part according to an embodiment of the present invention will be described.

1 and 2, the fixing part 400 may selectively fix the table 120 provided on the support part 100. Accordingly, the table 120 may not be rotated because the table 120 is fixed by the operation of the fixing part 400, or the table 120 may be rotated by the rotational force of the power member 320 because the table 120 is not fixed. The fixing part 400 includes a fixing body 450, a braking member 410, and a driving member 420.

The fixture 450 is disposed in a path along which the braking member 410 moves so that it can contact the braking member 410. The fixture 450 is formed to surround the lower circumference of the rotating member 310. The fixture 450 is installed inside the bed 110. For example, the fixture 450 may be manufactured separately from the bed 110 and combined, or may be manufactured integrally with the bed 110. The fixture 450 may be installed so as not to rotate.

The braking member 410 may be formed in a circular plate shape. It is connected to the first rotating body 331. In detail, the braking member 410 may be disposed between the rotating member 310 and the first rotating body 331. Accordingly, the braking member 410 may rotate together with the first rotating body 331. At least a portion of the braking member 410 may protrude to the outside of at least one of the rotation member 310 and the first rotation body 331. The planar area of the braking member 410 may be larger than the planar area of the first rotating body 331. Accordingly, the protruding portion of the braking member 410 may contact the fixture 450.

In addition, the braking member 410 may be disposed under the fixture 450 and may be installed to be movable up and down. Accordingly, when the braking member 410 moves upward, it may contact the lower surface of the fixture 450, and when the braking member 410 moves downward, it may be spaced apart from the fixture 450. When the braking member 410 comes into contact with the fixing body 450, friction may occur between the braking member 410 and the fixing body 450, so that rotation of the braking member 410 may be restricted. Accordingly, the first rotating body 331 and the rotating member 310 connected to the braking member 410 are also limited, so that the table 120 may not rotate and may be fixed.

In this case, a plurality of protrusions may be formed on the upper surface of the braking member 410. Alternatively, the surface roughness of the upper surface of the braking member 410 may be roughly formed. Accordingly, the strength of the frictional force generated between the braking member 410 and the fixture 450 may be increased. Accordingly, the first rotating body 331 and the rotating member 310 may be more stably fixed by the braking member 410.

In addition, it may be detachably connected to the first rotating body 331. For example, a fastening bolt may pass through the braking member 410 and be fastened to the first rotating body 331. The braking member 410 may be provided with a fastener 412 through which a fastening bolt may pass as shown in FIG. 3. Accordingly, when the fastening bolt is released, the fastening bolt can be separated from the first rotating body 331. Therefore, if the used braking member 410 is damaged, it may be separated from the first rotating body 331 and then a new braking member 410 may be mounted on the first rotating body 331 and used.

In this case, the braking member 410 may be formed of an iron plate. Holes 411 may be provided in the braking member 410 so that the braking member 410 has flexibility. The hole 411 passes through the braking member 410 in the vertical direction. The hole 411 may extend along at least a portion of the circumferential shape of the braking member 410. A plurality of holes 411 may be provided and may be arranged in a ring shape along the circumference of the body of the braking member 410. Accordingly, since the braking member 410 may have flexibility, when it comes into contact with the fixing body 450, the braking member 410 may be prevented from being deformed or broken due to friction with the fixing body 450. Accordingly, durability and life of the braking member 410 may be extended.

In addition, as shown in FIG. 3, a through hole through which the rotating member 310 can penetrate may be formed in the center of the braking member 410. However, the structure and shape of the braking member 410 and a method of being coupled to the first rotating body 331 are not limited thereto and may be various.

The driving member 420 is disposed under the braking member 410. The driving member 420 may move the braking member 410 up and down. Accordingly, the braking member 410 may contact the fixture 450 or be spaced apart from the fixture 450 by the operation of the driving member 420. The driving member 420 includes a pusher member 425, a contact body 421, and a first driver 422.

The pusher member 425 may be supported by contacting the driving member 420. It may be formed to surround at least a portion of the first rotating body 331. For example, as shown in FIG. 4, the pusher member 425 may be formed in a circular shape to surround the circumference of the first rotating body 331. The central portion of the pusher member 425 may be empty, and one side may be open. Accordingly, the first rotating body 331 may be disposed in the center of the pusher member 425 to rotate, and the belt 333 may pass through the open side of the pusher member 425.

In addition, the pusher member 425 may be disposed under the braking member 410 and installed to be movable up and down. Thus, when the pusher member 425 moves upward, it contacts the lower surface of the brake member 410 and lifts the brake member 410 upward, so that the brake member 410 contacts the lower surface of the fixture 450 I can make it. When the pusher member 425 moves downward, it is spaced apart from the braking member 410, and the braking member 410 may move downward by its own weight, thereby being spaced apart from the fixture 450.

At this time, since the pusher member 425 and the first rotating body 331 are spaced apart from each other, they do not affect their movement. Accordingly, the pusher member 425 and the first rotating body 331 may be positioned at the same height or at a height where at least some of them may overlap each other, and the pusher member 425 may stably move up and down. Accordingly, the pusher member 425 and the first rotating body 331 are overlapped to reduce the height of the device, and space utilization may be improved.

On the other hand, the pusher member may be formed in a ring or disk shape. That is, a pusher member may be formed along the shape of the lower surface of the contact body 421. Accordingly, the pusher member can stably contact the contact body 421 to stably lift the contact body 421 upward. In this case, the pusher member may be spaced apart from the first rotating body 331 and may move up and down from the upper side of the first rotating body 331.

2 and 4, the contact body 421 may contact the pusher member 425. The contact body 421 supports the pusher member 425 and may push the pusher member 425 upward. The contact body 421 may extend in a direction crossing the vertical direction.

In addition, a contact surface between the contact body 421 and the pusher member 425 may have an inclined surface or a round surface. Since the contact surface between the contact body 421 and the pusher member 425 has an inclined surface or a round surface, the contact body 421 can move the pusher member 425 in the vertical direction in a direction crossing the vertical direction. The contact body 421 and the pusher member 425 are movable in a direction crossing each other.

For example, the pusher member 425 may be installed to be movable in the vertical direction, and the contact body 421 may be installed to be movable in the front-rear direction or left-right direction. Accordingly, the pusher member 425 may be pushed on an inclined surface or a round surface of the contact body 421 and may rise upward, or may move downward by a load on the inclined or round surface. Alternatively, the inclined surface or round surface formed on the pusher member 425 may be pushed by the contact body 421 to rise upward, or the inclined surface or round surface formed on the pusher member 425 may move downward along the contact body 421 . Therefore, even if the contact body 421 moves in a direction different from that of the pusher member 425 by the inclined or round surface, the pusher member 425 can be moved up and down. That is, by transmitting a force to the pusher member 425 in a direction crossing the moving direction of the contact body 421, the pusher member 425 can be moved up and down.

Meanwhile, the edge of one end contacting the pusher member 425 in the contact body 421 is processed into a tapered shape or a round shape, and the lower edge in contact with the contact body 421 at the pusher member 425 is tapered or rounded. Can be processed into shape. Accordingly, the lower end of the pusher member 425 may be formed to have a narrower width toward the lower side, and the contact body 421 may be formed to have a narrower width as one end of the pusher member 425 approaches the pusher member 425.

In this case, if both the contact surfaces of the contact body 421 and the pusher member 425 have an inclined surface, the contact area between the contact body 421 and the pusher member 425 may be increased. Accordingly, the contact body 421 can stably support the pusher member 425, and the contact body 421 can easily lift the pusher member 425 upward. That is, the force by which the contact body 421 moves can be easily transmitted to the pusher member 425.

The inclined surface provided on the contact body 421 may have an angle of 20 or more to 80 degrees or less based on the vertical line. If the inclined surface provided on the contact body 421 has an angle of less than 20 degrees, the distance through which the contact body 421 moves the pusher member 425 up and down may be shortened. Accordingly, it may be difficult to move the pusher member 425 to a position where it can contact the first rotating body 331. When the angle of the inclined surface provided in the contact body 421 exceeds 80 degrees, the distance in which the pusher member 425 moves may increase too much compared to the distance in which the contact body 421 is moved. Accordingly, it may be difficult to precisely control the position of the pusher member 425 by controlling the movement of the contact body 421. While the pusher member 425 is easily moved to the contact body 421, the angle of the inclined surface can be adjusted so that the position of the pusher member 425 can be precisely controlled.

In addition, since the contact body 421 moves in the direction crossing the pusher member 425, space utilization can be improved. That is, when the contact body 421 moves up and down in the same way as the pusher member 425, a space in which the contact body 421 can move up and down must be secured, so that the device can be formed long in the vertical direction. have. However, since the contact body 421 moves in a direction crossing the vertical direction, the height of the device in the vertical direction can be lowered, and space utilization can be improved.

At this time, the contact body 421 may be installed to be movable on the bed 110. For example, a guide hole 111 may be formed in the bed 110 so that the contact body 421 can move, and at least a part of the contact body 421 may be installed to be movable in and out of the guide hole 111. I can.

In addition, a plurality of contact bodies 421 may be provided to be disposed along the circumference of the pusher member 425. Accordingly, the plurality of contact bodies 421 may lift different portions of the pusher member 425 upward.

For example, at least some of the plurality of contact bodies 421 may be symmetrically disposed with respect to the center of the pusher member 425. Accordingly, the contact bodies 421 may move the same distance together to become close together, or the distance apart from each other may increase. Therefore, the pusher member 425 can move vertically vertically without losing the balance, and the pusher member 425 stably contacts the first rotating body 331 to brake the first rotating body 331 or Can be fixed.

The first driver 422 is connected to the other end of the contact body 421. The first driver 422 may be installed on the bed 110. The first driver 422 may be provided as many as the number of contacts 421 is provided. The first driver 422 may move the contact body 421 in a direction crossing the vertical direction. That is, the first driver 422 may move the contact body 421 toward the center of the pusher member 425 or toward the outside of the pusher member 425. For example, the first actuator 422 may be a cylinder. Accordingly, when the contact body 421 moves toward the center of the pusher member 425 by the first actuator 422, the pusher member 425 may move upward and contact the braking member 410. When the contact body 421 moves toward the outside of the pusher member 425 by the first driver 422, the pusher member 425 may move downward to be spaced apart from the braking member 410. However, the method of moving the contact body 421 by the first driver 422 is not limited thereto and may be various.

Meanwhile, the vertical machining center 1000 may further include a control unit (not shown). The control unit may control the operation of the rotating unit 300 and the fixing unit 400 according to the type of work. That is, the control unit may control the operation of the rotating unit 300 and the fixing unit 400 according to the type of work input by the operator to the control unit.

For example, when processing while rotating the workpiece M, the controller may control the operation of the first actuator 422 to move the contact body 421 to the outside of the pusher member 425. Accordingly, the contact body 421 may move downward so that the pusher member 425 may be spaced apart from the braking member 410. Therefore, when the control unit generates a rotational force to the power member 320, the first rotation body 331 can freely rotate by the rotational force of the power member 320, and the rotation member 310 rotates while the table 120 Can be rotated. When the table 120 rotates, the workpiece M supported on the table 120 may rotate, and the rotating workpiece M may be processed by controlling the operation of the processing unit 200.

In the case of processing while the workpiece M is fixed, the control unit may control the operation of the first actuator 422 to move the contact body 421 to the center of the pusher member 425. Accordingly, the pusher member 425 may move upward to contact the braking member 410, and lift the braking member 410 upward to bring the braking member 410 into contact with the fixture 450. Therefore, friction occurs between the braking member 410 and the fixture 450, so that the rotation of the first rotating body 331 may be limited, and the rotation member 310 and the table 120 may also be limited in rotation. I can. In this case, since the control unit stops the braking member 410 and does not generate rotational force, it is possible to prevent a load from being applied to the fixing unit 400 and improve the life of the device. Since the table 120 is maintained in a stopped state by the braking member 410, the workpiece S in a fixed state without rotating can be processed by the processing unit 200.

In addition, when the processing unit 200 processes the workpiece S, even if vibration or the like occurs, the table 120 may be maintained in a fixed state by the braking member 410. Accordingly, the workpiece (M) can be stably processed, and work accuracy can be improved.

In this way, by controlling the operation of the fixing part 400, the workpiece M may be selectively fixed or rotated. Accordingly, it is possible to perform both the work of processing the fixed work M and the work of processing the rotating work M in one device.

5 is a view showing a structure of a fixing part according to another embodiment of the present invention, and FIG. 6 is a plan view showing an operation structure of a fixing part according to another embodiment of the present invention.

5 and 6, the fixing part 400 may further include a fixing member 430. The fixing member 430 may be installed to fix the rotating member 310. The fixing member 430 includes a friction body 431 and a second driver 432.

The friction body 431 may be formed in a plate shape. The friction body 431 is formed to wrap at least a portion of the rotating member 310. For example, when the circumference of the rotating member 310 is circular, one surface of the friction body 431 facing the rotating member 310 may be formed to have a bend.

In addition, the friction body 431 may be disposed to face the rotating member 310. The friction body 431 may move toward the rotating member 310 or may move outside the rotating member 310. Accordingly, the friction body 431 may contact or be spaced apart from the rotating member 310. When the friction body 431 contacts the rotating member 310, rotation of the rotating member 310 may be hindered or the rotating member 310 may be fixed.

A plurality of friction bodies 431 may be provided to be installed along the circumference of the rotating member 310. A plurality of friction bodies 431 may hold the rotating member 310 and block rotation of the rotating member 310. Accordingly, it is possible to more effectively fix the rotating member 310.

For example, the plurality of friction bodies 432 may be symmetrically disposed with respect to the center of the rotating member 310. Accordingly, a load of the same or similar size may be applied to each friction body 432, and the friction bodies 432 may stably fix the rotating member 310.

The second driver 432 is connected to the other surface of the friction body 431. The second driver 432 may be installed on the bed 110. For example, a groove into which the second driver 432 can be inserted may be formed in the bed 110. Accordingly, the second driver 432 may move the friction body 431 between the bed 110 and the rotating member 310.

In addition, the second driver 432 may be provided as many as the number of friction bodies 431 are provided. The second driver 432 may move the friction body 431 in a direction crossing the vertical direction. That is, the second driver 432 may move the friction body 431 toward the rotating member 310 or may move toward the outer side of the rotating member 310. For example, the second actuator 432 may be a cylinder. Accordingly, when the friction body 431 is moved toward the rotation member 310 by the second driver 432, the friction body 431 contacts the rotation member 310 and the friction body 431 and the rotation member 310 ) May cause friction. When the friction body 431 moves toward the outside of the rotation member 310 by the second driver 432, the friction body 431 and the rotation member 310 may be spaced apart from each other.

The braking member 410 may limit the rotation of the first rotating body 331, and the friction body 431 may limit the rotation of the rotating member 310. That is, it is possible to limit the rotation of the table 120 double. Accordingly, the rotation of the table 120 is limited, and the processing operation performed while the workpiece M is fixed can be performed more stably. When the rotation of the table 120 is restricted by at least one of the braking member 410 and the friction body 431, the rotational force may not be generated by controlling the operation of the power member 320.

On the contrary, if the braking member 410 does not limit the rotation of the first rotating body 331, and the friction body 431 does not limit the rotation of the rotating member 310, the table 120 by the rotating unit 300 It can rotate freely. Accordingly, it is possible to perform a processing operation while rotating the table 120 to rotate the workpiece (M).

In this way, the work of rotating the work M and the work of fixing and processing the work M can be performed in one vertical machining center 1000. Since the two processes can be performed together in one device, the efficiency of the work of processing the workpiece M can be improved.

In addition, since two processes can be performed together in one device, two processes can be performed at one location without carrying the workpiece M to another location. Accordingly, it is possible to prevent the position where the workpiece M is seated from being changed. Therefore, since two operations can be performed on the workpiece M seated in the same position, processing precision can be improved.

In addition, devices for performing the two processes may not be separately provided. Accordingly, the space utilization of the workplace can be improved, and the cost of providing the device can be reduced.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined by the claims to be described below, as well as by the claims and equivalents.
