Description

[0001] HYBRID MACHINING EQUIPMENT [0002]

The present invention relates to a composite machining apparatus having excellent machining performance, and more particularly, to a machining apparatus capable of minimizing defects occurring in a jig and a machining entrance and an exit provided on a lower surface of a workpiece, Processing equipment.

In recent years, carbon fiber composite materials (CFRP) have attracted attention as a lightweight structural material with high strength and high elasticity in the fields of aviation, automobiles and ships, and their usage is also increasing.

Carbon fiber composites (CFRP) have excellent properties as lightweight structural materials. For example, the specific strength is six times that of steel, twice that of glass fiber reinforced plastics (GFRP), the non-elasticity ratio is three times that of steel, It has excellent fatigue characteristics (fatigue characteristics) as well as strength, and is excellent in abrasion resistance and abrasion resistance. In addition, it has excellent dimensional stability because of its small coefficient of thermal expansion and excellent performance in electrical conductivity, corrosion resistance, vibration damping property and X-ray permeability.

Various types of structures are required for the aeronautical, marine, and automobile fields as well as carbon fiber composite materials. Accordingly, various structures are provided to support the structures at a predetermined height from the ground in order to facilitate the work. In particular, when a curved surface structure forming a curved surface is to be machined, a plurality of jigs are provided for stably supporting the structure corresponding to the curved surface. Specifically, in the case of a curved structure, there is a high possibility that a process error occurs because the jig is detached from the jig due to gravity or processing force, or the precision process does not proceed. When a jig does not exist on the lower side of the machining position at the time of machining, the curved surface structure may be deformed due to the machining force. Therefore, conventionally, a plurality of jigs are provided below the curved structure to fix and support the curved structure.

However, the conventional method of fixing and supporting a curved structure using a plurality of jigs has inconvenience because each jig must be individually controlled. For example, if twenty jigs are needed to stably support a curved structure, the user would have to individually adjust the height for twenty jigs and adjust the jig again in response to the shape of the curved structure. Therefore, in the conventional method, the process of fixing and supporting the curved surface structure is complicated, and the time required for fixing and supporting the curved surface structure is prolonged. That is, the productivity of the final product is deteriorated.

Further, when the work piece is subjected to hole machining, the diameter of the cutting edge varies depending on the size of the hole. However, conventionally, there is no technique for changing the diameter of the jig corresponding to the diameter of the cutting edge. Therefore, if the diameter of each cutting edge is changed, it is inconvenient to replace the jig having a corresponding diameter.

However, the shape of the guide portion 160 for conveying the rear support portion 170 is not limited to that of the embodiment, and if the guide portion 160 is configured to move the rear support portion 170, . For example, the guide unit 160 may be configured to include a configuration such as a magnetic levitation or a wheel.

The rear support part 170 can closely support the lower surface of the processing part of the workpiece W to be processed by the processing part 150. [ The rear support portion 170 includes a fixed unit 171, a main body unit 176, and a rotation unit 177.

First, the main body unit 176 is coupled to the guide unit 160 and is moved to a position corresponding to the machining area, and is adjustable in length. Specifically, the main body unit 176 includes a first body 176a and a second body 176b. The first body 176a is coupled to the upper portion of the second rail 162, Of the second rail (162) in the longitudinal direction of the second rail (162). The second body 176b may extend upward from the first body 176a. For example, the second body 176b may be formed as a multi-stage boom with the first body 176a, or may be provided in a folding manner. Therefore, the rear support part 170 can support the workpiece W in correspondence with the height of the workpiece W by adjusting the length of the main body unit 176.

The rotation unit 177 can connect the main unit 176 and the fixed unit 171. At this time, the rotating unit 177 may be provided so that the fixed unit 171 can rotate in correspondence with the shape of the material W to be processed. That is, the fixed unit 171 can freely flow in the front, rear, left, and right directions on the upper side of the main body unit 176 by the rotation unit 177 and can support the shape of the workpiece W . Particularly, the fixed unit 171 can support the workpiece W so as to face the cutting unit 154 and have the same central axis when the workpiece W is machined. For this purpose, the rotating unit 177 may be provided as a ball joint. However, the rotating unit 177 is not limited to a ball joint. If the rotating unit 177 can be adjusted and fixed such that the fixed unit 171 is in close contact with the lower surface of the material to be processed W Are all included in one embodiment.

The fixed unit 171 is provided so as to closely support the lower surface of the machining portion of the workpiece W to be machined by the machining portion 150. In particular, And a control unit for controlling the control unit. Here, a method of adjusting the diameter of the fixed unit 171 will be described later. The fixed unit 171 includes a base body 172 and a rear support body 173.

The base body 172 may be coupled to a lower portion of the rear support body 173 and an upper portion of the rotation unit 177. A support groove 172a may be formed on the upper surface of the base body 172 to allow a plurality of the rear support members 173 to be coupled therewith. The support groove 172a may be formed along a path in which the rear support body 173 slides and moves. For example, as shown in the figure, when the base body 172 is provided in the shape of a square plate, and the rear support body 173 is provided by four, the support groove 172a is formed in the center of the upper surface of the base body 172 In the direction of the vertex. The number and position of the support grooves 172a may be formed corresponding to the number and position of the rear support members 173.

A plurality of the rear supports 173 may be provided, and a plurality of the rear supports 173 may be circular. The plurality of rear support members 173 may be provided so as to be close to and spaced from each other while maintaining a circular shape. The rear support members 173 may be spaced apart from each other or corresponding to the diameter of the cutting unit 154. For example, when the diameter of the cutting unit 154 is large, a plurality of the rear supports 173 may be spaced apart from each other while maintaining a circular shape. The rear support member 173 is made of an elastic material and deformed to correspond to the shape of the workpiece W and can be closely attached to the workpiece W. [ Therefore, when the workpiece W is machined by the cutting unit 154, the rear surface support 173 can be closely attached to the lower surface of the machined portion. That is, the workpiece W can be precisely machined without causing deformation such as warpage due to the machining pressure transmitted by the cutting unit 154.

The fixed unit 171 may further include a load cell 174 disposed under the base body 172 and measuring a working load by the processing unit 150. The fixed unit 171 may further include a first control unit 175 connected to the load cell 174, the processing unit 150, and a plurality of the rear supports 173. When the machining load exceeds the control load, the first control unit 175 provided as described above controls the rotational speed of the cutting unit 154, the descending speed of the cutting unit 154, and the rotational speed of the plurality of rear supports 173 Or the diameter formed by the outer circumferential surface of the outer circumferential surface. Here, the control load can be set in advance according to the characteristics of the material to be processed (W) at the maximum allowable value of the working load at which no defects such as the peeling phenomenon do not occur in the material to be processed (W).

The rotation unit 177 rotates the fixing unit 171 so that the rear support body 173 is brought into close contact with the lower surface of the delamination zone expected to be generated in the workpiece W . Specifically, when the material to be processed (W) is a carbon fiber composite material, the material to be processed (W) is determined to have a peeling zone in which the peeling defect is likely to occur, depending on the direction of lamination or physical properties of the bottom layer. When the plurality of rear supports 173 are spaced apart from each other while maintaining a circular shape, a gap between adjacent rear supports 173 is opened. That is, as the diameter of the hole to be machined by the cutting unit 154 becomes larger, the plurality of the rear supports 173 are spaced apart from each other so that the distance between the rear supports 173 becomes larger, A blank portion which can not directly receive the lower surface of the workpiece W is generated. Therefore, the rotating unit 177 can rotate the fixing unit 171 so that the rear supporting body 173 can directly contact and support the lower surface of the peeling zone of the material W to be processed. The rotating unit 177 thus provided can prevent a problem that a defect that the bottom layer of the material to be processed W peels off occurs.

The rear support part 170 may further include an X-ray unit 178. [ Specifically, the X-ray unit 178 may be provided on one side of the main body unit 176, and the position of the processing unit 150 may be determined by irradiating X-rays toward the processing unit 150 . Specifically, the X-ray unit 178 can radiate X-rays upward or upward at a constant interval. The carbon fiber composite material has a high X-ray transmittance. Therefore, when the workpiece W is made of a carbon fiber composite material, the X-ray can pass through the workpiece W and reach the machining portion 150 located above the workpiece W. [ That is, the X-ray unit 178 can grasp the position of the processing unit 150 by irradiating X-rays.

The processing unit 150 may further include at least one display member (not shown) made of a material having a high absorption rate of X-rays. One or more such display members may be provided so that the X-ray unit 178 absorbs the X-rays irradiated toward the processing unit 150 so that the X-ray unit 178 moves the position of the processing unit 150 So that it can be grasped more quickly and accurately. However, the display member may be formed of a material having high reflectance of x-rays. That is, the display member may include all of the structures that facilitate the position of the processing unit 150 to be grasped by the X-ray unit 178.

The second control unit 179 may be connected to the main body unit 176 and the second control unit 179 may be provided in the vicinity of the processing unit 150 received from the X- So that the main body unit 176 moves along the position. Accordingly, the second control unit 179 can promptly move the main body unit 176 to a position corresponding to the processing unit 150 in real time.

The complex machining apparatus 100 having excellent machining performance according to an embodiment of the present invention minimizes the number of the jig portions 120 required for fixing the workpiece W to reduce the purchase cost of the jig portion 120 Can be saved. As the number of the jig 120 is minimized, the time required for fixing the workpiece W using the jig 120 is greatly reduced.

Since the lower surface of the processed portion of the workpiece W is directly supported by the rear support portion 170 in the complex machining apparatus 100 having excellent machining performance according to the embodiment, W can be precisely machined even when the number of the jig portions 120 supporting the workpiece W is small.

The front support unit 281 may be provided at a lower portion of the processing unit body 253 forming the body of the processing unit 250 and may extend so that the lower end thereof is in close contact with the upper surface of the material W to be processed. The front support unit 281 includes a first front support 282 and a second front support 283.

The first front support body 282 is formed in the lower part of the processing body 253 and hollow inside so that the cutting unit 254 is provided therein. Can be extended. The first front support body 282 extends downward from the machining unit body 253 so that when the cutting unit 254 processes the workpiece W, . Although the first front support 282 is shown as a columnar shape having open top and bottom surfaces, the shape of the first front support 282 is not limited to the illustrated shape.

Also, the first front support body 282 can be inserted into the body 253 of the processing unit, and the length can be adjusted. For example, the first front support body 282 may be configured such that when the cutting unit 254 performs a machining operation on the workpiece W, the cutting unit 254 moves the length inserted into the workpiece W The first front support body 282 may be inserted into the body of the processing unit 253. [

The second front support body 283 may have one end coupled to the lower end of the first front support body 282 and the other end connected to the upper surface of the workpiece W. [ Specifically, the second front support body 283 may have one end extending from the first front support body 282 and the other end extending from the lower end. That is, the first front support body 282 and the second front support body 283 may be extended to be integrated with each other.

Further, the second front support body 283 may be an elastic material.
