  However, in the case where the above-described machining parts that require a plurality of machining are performed by individual machines, the total required for machining the machining parts by spending time for setup for machining. There was the inconvenience that it took time. That is, there is a problem that it is impossible to respond to a request to perform processing efficiently and in a short time.

  The present invention has been made to solve the above-described problems, and the problem to be solved by the present invention is that a plurality of types of machining can be performed with a single clamp fixed in a single machine. The purpose is to shorten the time required for machining. Furthermore, it is preferable to further reduce the time required for processing by performing one processing using a clamping operation by a clamp.

In order to achieve the above object, the multi-task machine according to the present invention takes the following means.
First, the basic solution of the present invention is as follows. This is a processing machine that performs processing by placing a long processed part such as a pipe-shaped part on a base and fixing it with a clamp. A plurality of clamps for fixing a workpiece to be mounted on the base are arranged on the base at intervals in the longitudinal direction of the workpiece. A cutter support provided with a disk-shaped cutter that is driven to rotate by a motor for cutting a cut part of a processed part is installed on the base so as to be movable forward and backward with respect to the processed part placed and fixed on the base. Yes. A punch support provided with a punch for plastic processing of a plastic processing part such as a hole processing to a processed part is also installed on the base so that it can be pressurized and moved with respect to the processed part mounted and fixed on the base. Yes.

  According to the above means, when processing a long processed part such as a pipe-shaped part, a plurality of types of plastic processing such as cutting with a cutter and punching with a punch are performed within a single clamp in the same process. It can be carried out. As a result, it is possible to shorten the time required for processing the processed part.

  Next, in the above basic solution, one clamp among a plurality of clamps is integrally formed with the punch support, a punch is set in the one clamp, and the one clamp is set as a plastic processing portion of a workpiece. The pressurizing movement by the clamp is first performed by plastic working on the processed part by the punch by the pressurizing movement, and after completion of the plastic working, the position of the clamp having the punch is used. It is preferable to use a means for pressurizing the workpiece and performing a positioning function for the workpiece.

  By using the above means, plastic processing such as hole processing is performed together with the clamping action by the clamp, so that it is possible to further shorten the time required for processing the processed part. In addition, since the punch performs the positioning function for the processed part in the plastic processing completed state, the clamping function can be achieved more reliably.

Further, in each of the above-described solving means, the base is further provided with a chamfering means supporting means for chamfering a cut surface of a processed part cut by a cutter at a cutting position of the processed part. It is preferable to install it so that it can approach and move. The chamfering means at this time is preferably a buff or a wire brush.
By using the above-mentioned means, it is possible to perform chamfering of a cut surface of a processed part in a single fixed state by a clamp. Therefore, the processing time can be further shortened.

As described above, the present invention enables a plurality of processes in a single clamp in the same process by a single processing machine, thereby achieving the desired problem of shortening the time required for processing a processed part. An effect can be obtained. In this case, in addition to plastic processing such as cutting and drilling, chamfering that removes burrs and the like that occurs when cutting is performed is further shortened when the clamp is fixed once. Can be achieved.
Further, when plastic processing such as drilling is performed using the clamping operation by clamping, the time required for processing can be further shortened.

Hereinafter, an embodiment of the best mode for carrying out the present invention will be described with reference to the drawings. The combined processing machine of this embodiment is capable of performing three types of processing: cutting with a cutter, plastic processing for punching with a punch, and chamfering with a wire brush with a single processing machine. Furthermore, two processed parts can be processed simultaneously.
The overall configuration of the multi-tasking machine of this embodiment is shown in FIGS. 1 is a side view, FIG. 2 is a plan view, FIG. 3 is a front view, and FIG. 4 is a view taken along line (4)-(4) in FIG.

As shown in FIG. 1, in the combined processing machine 100 of this embodiment, first, a disk-shaped cutter 20 is arranged above the base 10 so as to be movable up and down. A predetermined portion of the workpiece W placed on the base 10 is cut by the downward movement of the cutter 20. The workpiece W is mounted on the mounting tables 32 and 42 that are appropriately assembled on the upper surface of the base 10, clamped by the first clamp 30 and the second clamp 40, and fixed on the base 10.
The cutter 20 is rotatably provided on the cutter support 22. The cutter support 22 is mounted on the slide guide member 14 so as to be slidable up and down on the slide guide member 14 disposed in the vertical direction as viewed in FIG. The slide guide member 14 is fixed to a column 12 standing on the base 10 by bolting. Therefore, the base 10, the support 12, and the slide guide member 14 are in an integral relationship, and the cutter support 22 including the cutter 20 can move up and down relatively with respect to the base 10. Is set to
The slide guide member 14 to which the cutter support 22 is mounted is formed so that the shape of the front surface on which the cutter support 22 slides is inclined downward to the left as viewed in FIG. Therefore, the vertical movement of the cutter 20 is also slightly inclined. This tilted vertical movement is a movement that advances and retreats with respect to the workpiece W mounted on the mounting tables 32 and 42.
As shown in FIG. 1, a vertical slide motor 16 is installed above the slide guide member 14. The cutter support 22 can be moved up and down by driving the vertical slide motor 16. Although illustration of the drive mechanism is omitted, a known drive mechanism can be used as appropriate. For example, a vertical movement mechanism using a ball screw system, a worm gear system, or the like. As the vertical slide motor 16, a hydraulic motor, an electric motor, an air motor, or the like can be appropriately selected and used.

As well shown in FIGS. 2 to 4, the cutter 20 is driven to rotate by a drive motor 24. The cutters 20 are respectively disposed on both sides of the drive motor 24, and two cutters having the same disk shape size are set. The drive motor 24 is integrated with the cutter support 22 by fastening means or the like. A cover 26 is provided on the cutter 20 so as to surround the upper half of the cutter 20. The cover 26 is also provided on each of the cutters 20 on both sides, and is supported by the cutter support 22. The cover 26 is provided from the viewpoint of worker safety. The drive motor 24 is usually preferably an electric motor, but may be a hydraulic motor or an air motor.
As shown in FIG. 3 and FIG. 4, the rotary drive configuration for the cutter 20 from the drive motor 24 includes rotary shafts 28, 28 arranged on both sides of the drive motor 24, and the rotary shafts 28, 28 are driven. A rotor (not shown) of the motor 24 is integrally connected. A disc-shaped cutter 20 is attached to the distal end portions of the rotary shafts 28 and 28. The cutter 20 is fixed so as to rotate integrally with the rotary shaft 28 by a fastener 29 such as a nut. Thereby, the rotation of the drive motor 24 is transmitted to the cutter 20 through the rotary shaft 28, and the cutter 20 is driven to rotate. The connection between the rotor of the drive motor 24 and the rotary shaft 28 is an integral connection that directly transmits the rotation of the rotor of the drive motor 24 in this embodiment. In order to rotate, it may be connected via a speed reduction mechanism or a speed increasing mechanism.

  The shape of the processed part W processed by the multi-tasking machine 100 of this embodiment is a curved, arched long shape as shown in FIG. The cross-sectional shape is a rectangular tube shape at the location of the first clamp 30 shown in FIG. The second clamp 40 shown in FIG. 6 has a circular tube shape. As for the overall shape, the cross-sectional shape of the lower end portion arranged in an arcuate shape as shown in FIG. 2 is a rectangular shape, but it is a circular shape from a midpoint located slightly above. . The upper end portion is a portion Ws cut by the cutter 20. As shown in FIG. 2, two processed parts W are arranged on both sides of the drive motor 24. As described above, the processed component W is placed on the two placement tables 32 and 42 installed on the base 10 as well shown in FIG.

As shown in FIG. 5, the first clamp 30 includes an operating cylinder 34 and a clamp member 36. The working cylinder 34 has a piston (not shown) therein, and a piston rod 35 connected to the piston projects upward. Therefore, the piston rod 35 moves up and down by the operation of the operation cylinder 34. As shown in FIG. 5, the upper end of the piston rod 35 and the left end of the clamp member 36 are connected by a pin coupling 30a.
The clamp member 36 is arranged in a position state where the upper part of the workpiece W can be clamped in the clamp position state. Clamping by the clamp member 36 is performed by a pressing portion 36a at a position below the right end of the clamp member 36 as seen in FIG.
As shown in FIG. 5, the clamp member 36 is supported so as to be swingable by a support arm 38 disposed at a position slightly to the left of the center position of the clamp member 36. The lower end of the support arm 38 is pin-coupled 30b to a member integral with the base 10, and the support arm 38 is attached so as to be swingable in the left-right direction as viewed in FIG. Similarly, the upper end portion of the support arm 38 is pin-coupled 30c to the clamp member 36, and both members 36 and 38 are coupled so as to be able to swing.

In the first clamp 30, the piston rod 35 is moved up and down by the operation of the operation cylinder 34, and the vertical movement of the piston rod 35 is transmitted to the clamp member 36 through the coupling pin 30 a. Since the clamp member 36 is connected and supported by a member that is integral with the base 10 via the coupling pins 38c and 38b of the support arm 38, the clamp member 36 is restrained in the vertical direction but can swing in the horizontal direction. It has become. Therefore, the clamp member 36 is rotated around the coupling pin 30c by the vertical movement of the piston rod 35 transmitted to the left end portion of the clamp member 36, and the support arm 38 is swung around the coupling pin 30b. 36 swings in the left-right direction. As a result of the combination of these two operations, the clamp member 36 swings between the position indicated by the solid line and the position indicated by the phantom line in FIG. The solid line position is the clamp state position, and the virtual line position is the clamp release state position.
When the processing component W is mounted on the first clamp 30 by the mounting table 32, a hole 70 is formed in the lower surface portion of the processing component W, and a protrusion 32 a provided on the upper portion of the mounting table 32 is in close contact with the hole 70. And is done by fitting. Therefore, the clamp of the processed component W by the first clamp 30 is positioned by fitting the hole 70 into the protrusion 32a of the mounting table 32 on the lower surface portion, and the upper surface portion of the processed component W is the pressing portion 36a of the clamp member 36. Is performed by pressing.

Next, the 2nd clamp 40 consists of the action | operation cylinder 44 and the clamp member 46, as FIG. 6 shows. The basic configuration is the same as the configuration of the first clamp 30 described above. That is, the working cylinder 44 has a piston (not shown) inside, and a piston rod 45 connected to the piston projects upward. Therefore, the piston rod 45 moves up and down by the operation of the operation cylinder 44. As shown in FIG. 6, the upper end portion of the piston rod 45 and the left end portion of the clamp member 46 are connected by a pin coupling 30a.
The clamp member 46 is arranged in a position state where the upper part of the workpiece W can be clamped in the clamp position state. Clamping by the clamp member 46 is performed by a product presser clamp metal 47 provided with a punch 47a provided at a position below the right end of the clamp member 46 as viewed in FIG. In this embodiment, the punch 47a is used to perform plastic processing for drilling the processed component W during the clamping operation by the second clamp.
As shown in FIG. 6, the clamp member 46 is swingably supported by a support arm 48 that is disposed slightly to the left of the center position of the clamp member 46. The lower end of the support arm 48 is pin-coupled 40b to a member integral with the base 10, and the support arm 48 is attached so as to be swingable in the left-right direction as viewed in FIG. Similarly, the upper end portion of the support arm 48 is pin-coupled 40c to the clamp member 46 so that both members 46 and 48 are coupled to each other in a swingable state.

The second clamp 40 operates in the same manner as the first clamp described above by the above configuration. That is, the piston rod 45 is moved up and down by the operation of the operating cylinder 44, and the vertical movement of the piston rod 45 is transmitted to the clamp member 46 through the coupling pin 40a. Since the clamp member 46 is connected and supported by a member that is integral with the base 10 via the coupling pins 48c and 48b of the support arm 48, the clamp member 46 is restrained in the vertical direction but can swing in the horizontal direction. It has become. Accordingly, the clamp member 46 is rotated around the coupling pin 40c by the vertical movement of the piston rod 45 transmitted to the left end portion of the clamp member 46, and the support arm 48 is swung around the coupling pin 40b, whereby the clamp member is moved. 46 swings in the left-right direction. As a result of combining these two operations, the clamp member 46 swings between the position indicated by the solid line and the position indicated by the phantom line in FIG. The solid line position is the clamp state position, and the virtual line position is the clamp release state position.
The processing part W is placed on the second clamp 40 by the mounting table 42. The upper surface of the mounting table 42 is formed as a concave receiving surface 42a, and the lower surface of the processing component W is mounted on the receiving surface 42a. Is done. The concave shape of the receiving surface 42a is a shape corresponding to the circular cross-sectional shape of the processed part W, so that the receiving surface 42a can be securely mounted without falling off the mounting table 42.

In this embodiment, as described above, the hole 72 is formed in the upper position of the processed part W corresponding to the position of the second clamp 40. This drilling is formed at the tip of the product presser clamp 47 when the product presser clamp 47 installed at the lower right end of the clamp member 46 presses the upper surface of the workpiece W by the clamping action of the clamp member 46. The hole 72 is opened by the punch 47a. The hole 72 may be directly formed by the punch 47a. However, a temporary hole is previously formed at the position of the hole 72 in the previous process or the like, and the drilling of the finishing process is punched by the combined processing machine 100 of this embodiment. It may be performed in 47a. In this embodiment, the clamp member 46 and the product presser clamp metal 47 function as a punch support in the present invention.
The clamp of the processed component W by the second clamp 40 is positioned by fitting the lower surface portion of the processed component W to the concave receiving surface 42a of the mounting table 42, and in the hole 72 formed in the upper surface portion of the processed component W. The punch 47a of the clamp member 46 is fitted and positioning in the longitudinal direction is performed, and the workpiece W is pressed by the clamp member 46 to perform positioning in the vertical direction. Together, these actions ensure that clamping is performed.
In addition, although each working cylinder 34 and 44 of the 1st and 2nd clamp in this Example is performed by oil_pressure | hydraulic, it may be performed by air etc.
The 1st clamp 30 and the 2nd clamp 40 which were demonstrated above are each arrange | positioned with respect to the process components W mounted in right and left, as shown in FIG.

The chamfering device 50 includes a cylinder 52, a rotation motor 54, and a wire brush 56 as well shown in FIG. The wire brush 56 is held by a brush support 56 a and is driven to rotate by a rotary motor 54. Two wire brushes 56 and rotary motors 54 are arranged symmetrically on both sides of the cylinder 52. The cylinder 52 operates so that the rotary motors 54 on both sides extend in the left-right direction as viewed in FIG.
Further, the cylinder 52 is movable in the vertical direction when the track portion 58 installed on the base 10 is viewed in FIG. The vertical movement direction of the cylinder 52 on the track portion 50 and the direction in which the rotary motors 54 and 54 and the wire brushes 56 and 56 on both sides of the cylinder 52 extend left and right are orthogonal to each other.
In this embodiment, the wire brush 56 is a chamfering means of the present invention, and the brush support 56a is a chamfering means support.
According to this chamfering device 50, the wire brushes 56, 56 can be moved closer to the cut portion of the workpiece W cut by the cutter 20. In the approaching movement, first, the cylinder 52 is moved on the track portion 58 and moved to the vertical position corresponding to the cut portion of the workpiece W as seen in FIG. Next, the cylinder 52 is operated to extend the wire brushes 56 on both sides in the left-right direction. The wire brushes 56 and 56 are moved to the retracted position by performing the reverse operation.
The cylinder 52 in the chamfering device 50 is preferably a hydraulic cylinder, but may be an air cylinder. The rotary motor 54 is preferably an electric motor, but may be an air motor.

Next, the processing action by the combined processing machine 100 of the above embodiment will be described in order.
First, the two processed parts W are mounted on the mounting bases 32 and 42 of the first clamp 30 and the second clamp 40 that are respectively arranged on the left and right as viewed in FIG. Then, both the operating cylinders 34 and 44 of both the clamps 30 and 40 are operated, and the upper surfaces of the workpiece W are pressed and clamped by the respective clamp members 36 and 46.
In this case, as shown in FIG. 5, in the first clamp 30, the pressing portion 36 a of the clamp member 36 presses the workpiece W, and in the second clamp 40, the lower right end of the clamp member 46 is shown in FIG. 6. The punch 47a of the product presser clamp metal 47 provided in is formed by making a hole 72 in the upper surface portion of the processed part W and pressing it.
In the clamping operation of the second clamp 40, plastic working is performed to open the hole 72 of the workpiece W by the punch 47a by the pressing action when the clamp member 46 is operated. The second clamp 30 is clamped in a state in which the punch 47a after the hole 72 is formed by the plastic working is fitted in the hole 72. That is, in this embodiment, since the plastic working for forming the hole 72 is performed together with the clamping operation of the second clamp 30, the working time can be shortened.
In a state in which the processed part W is clamped by the first clamp 30 and the second clamp 40, the longitudinal positioning of the processed part W is performed in the hole 70 of the protrusion 32a of the mounting table 32 of the first clamp 30. This is reliably performed by two places, that is, fitting and fitting of the second clamp 40 into the hole 72 of the punch 47a. The positioning in this case is performed on the lower surface portion of the processed component W in the case of the first clamp 30, and is performed on the upper surface portion of the processed component W in the case of the second clamp 40.

When the clamping of the workpiece W is completed by the first clamp 30 and the second clamp 40, the vertical slide motor 16 is then started to move the cutter support 22 downward. The cutter support 22 is lowered by the activation of the vertical slide motor 16.
On the other hand, the drive motor 24 which rotationally drives the cutter 20 is started together with the start of the up / down slide motor 16. The cutters 20 and 20 disposed on both sides of the drive motor 24 are rotated by the activation of the drive motor 24.
While the cutters 20 and 20 are rotated, the cutter support 22 that supports the cutters 20 and 20 is moved downward to also move the cutters 20 and 20 downward to cut the cut parts of the processed parts W and W. The phantom line state in FIG. 1 is a state in which the workpiece W is cut by the cutter 20. The cut piece Ws thus cut is shown in FIG. The cut piece Ws thus cut is treated as waste. In this way, the two workpieces W can be cut at a time by the downward movement of the cutter support 22 once, and the cutting operation is efficiently performed.
When the cutting process on the workpiece W is completed, the drive motor 24 is turned off to stop the rotation of the cutter 20, and the up / down slide motor 16 is activated to reversely move the cutter support 22 up and return to the retracted position.

When the cutting process by the cutter 20 is completed, the chamfering process is performed by the chamfering apparatus 50 that is well illustrated in FIG. In this processing, first, the cylinder is moved in the vertical direction on the track portion 58 as viewed in FIG. Next, the rotation motors 54 and 54 are activated to turn the wire brush 56 in a rotating state, the cylinder 52 is operated, the brush support 56a and the wire brush 56 are extended in the left-right direction, and the wire brush 56 is moved to the workpiece W. Make contact with the cut part. In this contact state, the wire brush 56 performs chamfering to remove burrs generated by the previous cutting process.
Also in this chamfering device 50, since the wire brushes 56 are disposed on both the left and right sides of the cylinder 52, it is possible to perform chamfering of the two processed parts W and W clamped by the processing machine at the same time.
According to the combined processing machine 100 of this embodiment, three types of processing, that is, cutting with a cutter, drilling with a punch, and chamfering with a wire brush, can be performed in a single clamp fixing state. Parts can be produced efficiently. In particular, in this embodiment, the hole machining by the punch is performed at the same time as the clamping work, so that the machining time can be further shortened.

As mentioned above, although one Example of this invention was described, this invention can consider various other embodiment.
For example, in the above-described embodiment, three types of processing, that is, cutting with a cutter, drilling with a punch, and chamfering with a wire brush, are performed by a single processing machine. However, when the chamfering process is not required or when the chamfering process can be efficiently performed in a subsequent process, the chamfering device 50 that performs the chamfering process with the wire brush 56 can be omitted.
In the above-described embodiment, the case where two processed parts are processed simultaneously has been described. However, one processed part may be processed.
Further, in the above embodiment, the hole machining by the punch is performed simultaneously with the clamping operation by the second clamp. However, in the case where the clamping position to the machining part is different from the position of the hole to be drilled in the machining part, A plastic working device for punching with a punch may be provided separately.
In the above embodiment, the chamfering means uses the wire brush 56, but may be a buff.

It is a front view which cuts and shows the upper and lower sides of the Example. It is the (4)-(4) line arrow figure of FIG. It is a side view which shows a 1st clamp. FIG. 6 is a side view showing a second clamp.
