The utility model provides a combined machining center of metalwork.

In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the composite machining center for metal parts includes a machine 100, a laser cutting device 200 and a CNC machining device 300. The machine 100 has a feeding rail 110, the laser cutting device 200 and the CNC processing device 300 are both installed on the machine 100, and the laser cutting device 200 and the CNC processing device 300 are arranged on the feeding rail 110 of the machine 100 at intervals.

It is understood that, in general, when a metal workpiece is machined, a raw material is cut into a desired size, and then the cut workpiece is subjected to finishing operations such as hole finishing, end face finishing, and step face machining. At present, the cutting operation and the finishing operation of the metal workpiece are respectively completed on two devices, and the workpiece needs to be transported to another device for finishing after being cut on one device. Therefore, the transportation cost is high, and the processing efficiency is low.

The technical scheme of this application, through the laser cutting device 200 of installation on the board 100, usable laser cutting device 200 is high-speed, high-efficient, the characteristic that machining precision is low, cuts off the metal work piece, operations such as trompil, draw-in groove carry out efficient rough machining, simultaneously through the CNC processingequipment 300 of installation on the board 100, the characteristic that usable CNC processingequipment 300 machining precision is high carries out processing such as hole tapping, groove finish milling, terminal surface finish milling, step face processing to metal work piece. It can be seen that, compared with the existing composite machining center for metal parts, the composite machining center for metal parts integrates the rough machining and the finish machining of the workpiece through the cooperative work of the laser cutting device 200 and the CNC machining device 300, omits the transportation process between two times of machining of the workpiece, realizes the assembly line operation, and greatly improves the machining efficiency of the workpiece.

Alternatively, in the present embodiment, the laser cutting device 200 and the CNC processing device 300 are arranged in sequence along the feeding direction of the machine 100. It can be understood that since the laser cutting device 200 can carry out rough machining to the workpiece, and the CNC machining device 300 can then carry out finish machining to the workpiece, consequently set gradually laser cutting device 200 and CNC machining device 300 along the direction of feed of board 100, can carry out efficient rough machining to the workpiece earlier, carry out finish machining again on the basis of rough machining, can greatly improve finish machining's machining efficiency to the maximum efficiency improves the machining efficiency of the combined machining center of metalwork. Of course, the design of the present application is not limited thereto, and in another embodiment of the present application, the CNC processing device 300 may be arranged at the feeding side of the laser cutting device 200, so that when processing the workpiece, the CNC processing device 300 may firstly perform operations such as milling, drilling and the like on the part of the whole workpiece on the feeding track 110, and then the laser cutting device 200 may cut off the processed part of the workpiece to obtain the required workpiece.

For convenience of description, an xyz three-axis coordinate system is established with the feeding direction of the tool 100 as the x-axis.

Specifically, in the present embodiment, the laser head of the laser cutting device 200 is movable in the y-axis direction and the z-axis direction, and the tool bit of the CNC machining device 300 is movable in the x-axis direction, the y-axis direction, and the z-axis direction.

With reference to fig. 1 and fig. 2, in the present embodiment, the feeding track 110 of the machine 100 includes a feeding section 111 and a processing section 112 sequentially arranged along the feeding direction of the machine 100, wherein the laser cutting device 200 and the CNC processing device 300 are both arranged on the processing section 112 of the feeding track 110. Specifically, since the workpieces are mostly strip-shaped materials, such as square tubes, plates, etc., the feeding rail 110 in the present application does not refer to a rail on which a conveyor belt or the like can support and transport the workpieces, but refers to a channel through which the workpieces can be fed in a certain direction. The feeding section 111 and the processing section 112 respectively mean that the workpiece is still in a feeding state in the feeding section 111 portion, and is processed by the laser cutting device 200 and the CNC processing device 300 in the processing section 112 portion. Specifically, in the present embodiment, the machine station 100 includes a feeding seat 120 and a processing table 130, wherein the feeding seat 120 is disposed corresponding to the feeding section 111, and the processing table 130 is disposed corresponding to the processing section 112, so as to facilitate feeding and processing of the workpiece.

Specifically, in the present embodiment, the workpiece machining apparatus further includes a supporting device 400, a clamping device 500, a turning device 600, and a chip remover 700. Wherein, the supporting device 400 is disposed on the feeding section 111 for supporting the workpiece; the clamping device 500 is arranged at the processing section 112 and is used for clamping the workpiece so as to facilitate the processing of the workpiece; the rotating device 600 is mounted on the feeding section 111 and used for clamping and driving the workpiece to rotate, and the workpiece is driven to rotate by the rotating device 600, so that the laser cutting device 200 and/or the CNC processing device 300 can conveniently process the circumferential direction of the workpiece, and the laser cutting device 200 can conveniently cut off the workpiece; the chip removal machine is mounted at the machining section 112 and is used for collecting chips falling from the workpiece of the CNC machining device 300 so as to keep the working space clean.

Further, as shown in fig. 3, in the present embodiment, the rotating devices 600 are installed at both ends of the feeding section 111 along the feeding direction of the machine table 100. It can be understood that since the workpiece is still in the feeding state in the feeding section 111, and the workpiece does not need to be processed, the rotating devices 600 mounted at both ends of the feeding section 111 can not only support the workpiece, but also improve the clamping strength of the workpiece, so as to rotate the workpiece. Specifically, in the present embodiment, two rotating devices 600 are respectively mounted on both ends of the feeding base 120. Of course, in some embodiments of the present application, 1, 3, 4, 5, and more sets of turning devices 600 may be disposed on the feeding section 111.

Referring to fig. 4, in the present embodiment, the rotation device 600 includes a base 610, a turntable 620, and a claw 630. The base 610 is mounted on the feeding base 120, the rotary table 620 is rotatably mounted on the base 610, a material passing channel is formed in the rotary table 620 for a workpiece to pass through, the claw 630 is movably arranged on the rotary table 620, the claw 630 has a clamping state and a releasing state, the claw 630 clamps the workpiece passing through the material passing channel in the clamping state, and the claw 630 releases clamping of the workpiece in the releasing state. It will be appreciated that when a workpiece is fed, the jaws 630 are in a release state, and when the workpiece is to be rotated, the jaws 630 are first switched to a gripping state to grip the workpiece, and then the turntable 620 is rotated to rotate the workpiece.

Preferably, in the present embodiment, the latch 630 is slidably mounted on the circumferential side of the turntable 620, and the latch 630 may be slidably switched between the clamping state and the releasing state. Of course, in other embodiments of the present application, the jaws 630 may be rotatably mounted on the periphery of the turntable 620, and the jaws 360 may rotate relative to the turntable 620 to clamp the workpiece. So set up, simple structure, it is convenient to realize, and the centre gripping dynamics of jack catch 630 is strong.

Further, in the embodiment, the rotating devices 600 at both ends of the feeding section 111 are slidably mounted on the machine 100, and the sliding direction of each rotating device 600 is parallel to the feeding direction of the machine 100. That is, both of the swiveling devices 600 can slide in the x-axis direction. It can be understood that the arrangement can adjust the distance between the two rotating devices 600 by sliding the two rotating devices 600 to adapt to the processing of workpieces with different requirements. Of course, in other embodiments of the present application, one of the two rotating devices 600 may be slidably mounted on the machine table 100 to adjust the distance between the two rotating devices 600.

Referring to fig. 3 and fig. 5, in the present embodiment, the rotating device 600 further includes a driving assembly 640, and the driving assembly 640 is used for driving the rotating device 600 to slide on the machine table 100. The driving assembly 640 drives the rotating device 600 to slide, so that the position of the rotating device 600 on the machine table 100 can be adjusted automatically/semi-automatically, and the working efficiency is high. Of course, in other embodiments of the present application, the sliding and fixing of the swing device 600 may also be manually driven.

Specifically, in the embodiment, the machine 100 is provided with a rack rail 140, and the rack rail 140 is specifically installed on the top of the feeding seat 120 and is arranged along the feeding direction of the machine 100.

The base 610 is slidably mounted on the feeding base 120, the driving device includes a driving motor 641 and a transmission gear 642, wherein the transmission gear 642 is rotatably mounted on the base 610 and engaged with the rack rail 140, and the driving motor 641 is mounted on the base 610 for driving the transmission gear 642 to rotate. Thus, the driving motor 641 drives the transmission gear 642 to rotate, and the transmission gear 642 rotates and advances along the extending direction of the rack rail 140, so as to drive the base 610 to slide along the feeding base 120. Meanwhile, the base 610 can be automatically fixed by self-locking the driving motor 641. Of course, in other embodiments of the present application, the sliding of the swiveling device 600 can also be realized by a pulling rope, a roller, etc.

Referring to fig. 3, 6 and 7, in the present embodiment, the supporting device 400 includes a bracket 410 and a rotating wheel 420, wherein the rotating wheel 420 is rotatably mounted on the bracket 410, the rotating wheel 420 has a rotating axis, the rotating wheel 420 is further provided with a first supporting arc surface 421a, the first supporting arc surface 421a extends around the rotating axis of the rotating wheel 420, and one end of the first supporting arc surface 421a in the extending direction gradually approaches the rotating shaft 423 of the rotating wheel 420 to the other end. It will be appreciated that the rotational axis of the wheel 420 extends in the same direction as the rotational axis 423.

When the composite machining center for metal parts machines a long workpiece, the workpiece is clamped at the machining device, and the support device is arranged at the feeding side of the machining device to support the workpiece, so that the workpiece is prevented from falling and deforming, and the machining precision is prevented from being affected. In the process of machining a workpiece, the workpiece is sometimes rotated to machine the circumferential direction of the workpiece. Besides the round tubular workpiece, during the rotation of most workpieces (such as square tube, etc.), the position of the workpiece in contact with the supporting device changes, that is, the actual required supporting height of the workpiece changes. The support height of the conventional support device cannot be adjusted, so that the workpiece cannot be supported in real time in the workpiece processing process, and the processing precision of the workpiece is influenced.

It can be understood that the technical scheme of the utility model, set up the first support cambered surface 421a that extends around the axis of rotation of runner 420 on runner 420 to set up this first support cambered surface 421a into and be close to runner 420 gradually from extending direction's one end to the other end, so, through runner 420 for the rotation of support 410, alright adjust the position that first support cambered surface 421a compares in support 410, thereby adjust runner 420's actual bearing height, and the different processing situation of adaptation work piece. Therefore, compared with the existing composite machining center for the metal part, the composite machining center for the metal part has the advantages that the workpiece can be supported in real time in the machining process, and the machining precision of the workpiece is improved.

Referring to fig. 9 and 10, in the present embodiment, the rotating wheel 420 is further provided with a second supporting arc surface 422a, the second supporting arc surface 422a extends around the rotating axis of the rotating wheel 420, and one end of the second supporting arc surface 422a in the extending direction gradually approaches the rotating shaft 423 from one end to the other end. Specifically, two ends of the second supporting arc surface 422a in the extending direction are respectively connected to two ends of the first supporting arc surface 421a in the extending direction, and one end of the second supporting arc surface 422a farthest from the rotating shaft 423 is connected to one end of the first supporting arc surface 421a farthest from the rotating shaft 423. Correspondingly, one end of the second supporting arc surface 422a closest to the rotating shaft 423 is connected with one end of the first supporting arc surface 421a closest to the rotating shaft 423. That is, in the present embodiment, the first supporting arc 421a and the second supporting arc 422a are disposed at two sides of the rotating wheel 420, and two ends are connected to each other. By the arrangement, the circumferential surface of the rotating wheel 420 can be used for supporting workpieces, and in the process of adjusting the actual supporting height by rotating the rotating wheel 420, the rotating wheel 420 can rotate clockwise or anticlockwise around the rotating axis, so that the limitation is low, and the operation is convenient. Of course, in other embodiments, only the first supporting arc 421a may be disposed on the rotating wheel 420, or both ends of the first supporting arc 421a and the second supporting arc 422a are not connected, or only one end is connected.

Preferably, in this embodiment, the junction between the first supporting arc 421a and the second supporting arc 422a is smoothly transited.

Referring to fig. 7 and 8, the rotating wheel 420 is further provided with a first limiting groove 421 for accommodating a workpiece, and a bottom wall of the first limiting groove 421 forms the first supporting arc surface 421 a. It can be understood that, by providing the first limit groove 421 on the rotating wheel 420, the position of the workpiece on the rotating wheel 420 can be limited, so as to maintain the consistency of the workpiece in the feeding direction, and further improve the processing precision of the workpiece. In this embodiment, the first position-limiting groove 421 is formed in the middle of the wheel 420 in a recessed manner, and in other embodiments, the first position-limiting groove 421 may be formed in a part of the wheel 420 in a raised manner. Of course, in other embodiments, a limiting structure such as a limiting post may be disposed on the wheel 420 to limit the position of the workpiece.

Specifically, the first supporting arc 421a has a distal end farthest from the rotation shaft 423 and a proximal end closest to the rotation shaft 423. The width of the first position-limiting groove 421 gradually decreases from the distal end of the first supporting arc 421a to the proximal end. In this regard, the present embodiment is explained by taking an aluminum square tube as an example, and not only the height of the portion of the workpiece in contact with the runner 420 is changed, but also the width of the portion of the workpiece in the first limit groove 421 is changed during the rotation of the workpiece. The groove width of the first limiting groove 421 is gradually reduced along the direction from the far end to the near end of the first supporting arc surface 421a, so that the actual supporting height of the rotating wheel 420 and the groove width of the first limiting groove 421 for accommodating the workpiece can be adjusted simultaneously in the rotating process of the rotating wheel 420, the workpiece can be supported and limited in real time, and the machining precision of the workpiece can be improved. It can be understood that the actual support height of the rotating wheel 420 is highest when the distal end of the first support arc 421a abuts against the workpiece, and the actual support height of the rotating wheel 420 is lowest when the proximal end of the first support arc 421a abuts against the workpiece.

Referring to fig. 9 and 10, in the present embodiment, the rotating wheel 420 is further provided with a second limiting groove 422, a second supporting arc surface 422a is formed on a bottom wall of the second limiting groove 422, a groove width of the second limiting groove 422 is gradually reduced along a direction from a distal end to a proximal end of the second supporting arc surface 422a, and two ends of the second limiting groove 422 are respectively communicated with two ends of the first limiting groove 421. That is, in the present embodiment, the wide end of the first position-limiting groove 421 communicates with the wide end of the second position-limiting groove 422, and the narrow end of the first position-limiting groove 421 communicates with the narrow end of the second position-limiting groove 422. It can be understood that, by providing the second limiting groove 422 on the rotating wheel 420, and two ends of the second limiting groove 422 are respectively communicated with the first limiting groove 421, when the rotating wheel 420 rotates to the second supporting arc surface 422a to abut against the workpiece, the position of the workpiece can be limited by the second limiting groove 422, so as to increase the limitation on the workpiece. Of course, for the manufacture of the rotor 420, the design can also reduce the difficulty of manufacturing the rotor 420 and save the cost. It should be noted that, in other embodiments of the present application, the groove width of the first position-limiting groove 421 and/or the second position-limiting groove 422 may also be kept constant.

Specifically, referring to fig. 7 to 10, in the present application, two sidewalls of the first and/or second retaining grooves 421 and 422 are inclined from the outer side to the inner side of the wheel 420 along the rotation axis of the wheel 420. By means of the arrangement, the groove width of the first limiting groove 421 and/or the second limiting groove 422 can be increased to the maximum extent so as to adapt to machining of more types of workpieces.

Specifically, in the present application, the side wall and the bottom wall of the first retaining groove 421 and/or the second retaining groove 422 are smoothly transited. The arrangement can reduce the resistance on the workpiece during rotation, and is convenient for the rotation of the workpiece.

Referring to fig. 7, in the present embodiment, the supporting device 400 further includes a first driving member 430, and the first driving member 430 is used for driving the rotating wheel 420 to rotate. It can be appreciated that by the first driving member 430 driving the rotating wheel 420 to rotate, the adaptive rotation of the rotating wheel 420 can be realized, thereby improving the processing efficiency of the workpiece. And the first driving member 430 is usually provided with a self-locking function, so that the rotating wheel 420 can keep a constant position after rotating a certain angle, so as to limit the workpiece. It should be noted that, to realize the adaptive adjustment of the rotating wheel 420, the first driving member 430 is directly controlled by the control system of the complex machining center of metal parts. The control system can preset various parameters of the workpiece, such as length, width and height, and is internally provided with an algorithm, the algorithm can calculate the required actual supporting height of the workpiece and the actual width in the first limiting groove 421 or the second limiting groove 422 according to the rotating angle of the workpiece, and then the first driving member 430 is controlled to drive the rotating wheel 420 to rotate according to the obtained actual supporting height. Obviously, the actual supporting height of the first supporting arc surface 421a on the rotating wheel 420 has a certain corresponding relationship with the groove width of the first limiting groove 421, so that the actual supporting height of the rotating wheel 420 can match the actual width of the workpiece in the first limiting groove 421. Accordingly, the actual supporting height of the second supporting arc surface 422a of the rotating wheel 420 and the groove width of the second limiting groove 422 have a corresponding relationship. It should also be noted that in other embodiments of the present application, the rotating wheel 420 can also be controlled to rotate and be fixed by manual adjustment.

Preferably, in this embodiment, the first driving member 430 is a motor, and the motor is in transmission connection with the rotating shaft 423 of the rotating wheel 420 through a first transmission belt 440. It will be appreciated that the motor, as a common first drive member 430, is technically mature, readily available and inexpensive. The output shaft of the motor is connected with the rotating shaft 423 of the rotating wheel 420 through the transmission of the first transmission belt 440, so that the motor can be installed on the side surface of the rotating wheel 420, the space is saved, and the space utilization rate is improved besides the advantages of the belt transmission.
