It can be understood that, in general, when processing a metal workpiece, the raw material is first cut to an expected size, and then finishing operations such as hole finishing, end face finishing, and step surface processing are performed on the cut workpiece. At present, the cutting operation and finishing operation of metal workpieces are completed on two kinds of equipment respectively. After the workpiece is cut on one equipment, it needs to be transported to another equipment for finishing.

Specifically, since the workpieces are mostly elongated materials, such as square tubes, plates, etc., the feeding track 110 referred to in this application is not a track such as a conveyor belt that can support and transport workpieces, but a virtual reference to the workpieces along a certain track. Directional feed channel. The feeding section 111 and the processing section 112 respectively refer to that the workpiece is still in the feeding state in the feeding section 111 , and is processed by the laser cutting device 200 and the CNC machining device 300 in the processing section 112 .

It can be understood that since the workpiece is still in the feeding state in the feeding section 111, the workpiece does not need to be processed. Therefore, installing the rotary devices 600 at both ends of the feeding section 111 can not only support the workpiece, but also improve the clamping strength of the workpiece. , in order to rotate the workpiece. Specifically, in this embodiment, the two rotating devices 600 are respectively installed on both ends of the feeding base 120 .

That is, both the rotating devices 600 can slide along the x-axis direction. It can be understood that the distance between the two rotating devices 600 can be adjusted by sliding the two rotating devices 600 in this way, so as 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 also be slidably installed on the machine table 100 to adjust the distance between the two rotating devices 600 .

The runner 420 is further provided with a first support arc surface 421a, the first support arc surface 421a extends around the rotation axis of the runner 420, and the first support arc surface 421a in the extending direction gradually approaches the rotation axis from one end to the other end. The shaft 423 of the wheel 420 . It can be understood that the rotation axis of the runner 420 and the rotation shaft 423 extend in the same direction.

It should be noted that when the composite machining center for metal parts is processing long workpieces, in addition to clamping the workpiece at the processing device, a support device will also be provided on the feeding side of the processing device to support the workpiece, avoiding The workpiece falls and deforms, which affects the machining accuracy. In the process of workpiece machining, the workpiece is sometimes rotated to process the circumferential direction of the workpiece. Except for cylindrical workpieces, during the rotation of most workpieces (such as square passes, etc.), the abutting position of the workpiece and the support device will change, that is, the actual required support height of the workpiece will change. However, the support height of the current support device cannot be adjusted, so that the workpiece cannot be supported in real time during the machining process of the workpiece, which affects the machining accuracy of the workpiece.

It can be understood that, in the technical solution of the present invention, a first supporting arc surface 421a extending around the rotation axis of the rotating wheel 420 is provided on the runner 420, and the first supporting arc surface 421a is arranged from one end of the extending direction to the other. One end is gradually approached to the runner 420. In this way, through the rotation of the runner 420 relative to the bracket 410, the position of the first supporting arc surface 421a relative to the bracket 410 can be adjusted, thereby adjusting the actual support height of the runner 420 to suit the workpiece. different processing conditions. It can be seen that, compared with the existing composite machining center for metal parts, the composite machining center for metal parts of the present application also has the advantage of being able to support the workpiece in real time during the machining process and improve the machining accuracy of the workpiece.

Referring to FIG. 9 and FIG. 10 , in this embodiment, the runner 420 is further provided with a second supporting arc surface 422a, the second supporting arc surface 422a extends around the rotation axis of the runner 420, and the second supporting arc surface 422a is The arc surface 422a is gradually approached to the rotating shaft 423 from one end to the other end in the extending direction. Specifically, both ends of the second supporting arc surface 422a in the extending direction are respectively connected to both ends of the first supporting arc surface 421a in the extending direction, and the end of the second supporting arc surface 422a farthest from the rotating shaft 423 is connected to the first supporting arc surface 422a. The arc surface 421a is in contact with the farthest end of the rotating shaft 423 . Correspondingly, the end of the second support arc surface 422a closest to the rotating shaft 423 is in contact with the end of the first support arc surface 421a closest to the rotating shaft 423 . That is, in this embodiment, the first support arc surface 421a and the second support arc surface 422a are disposed on both sides of the runner 420, and the two ends are in contact with each other. In this way, the peripheral surface of the runner 420 can be used to support the workpiece, and during the process of the runner 420 rotating to adjust the actual support height, the runner 420 can rotate clockwise or counterclockwise around the axis of rotation, which is less restrictive and convenient. operate. Of course, as in other embodiments, only the first supporting arc surface 421a may be provided on the runner 420, or the two ends of the first supporting arc surface 421a and the second supporting arc surface 422a may not be in contact, or only one end may be in contact with each other. catch.

Preferably, in this embodiment, the first support arc surface 421a and the second support arc surface 422a meet with a smooth transition.

7 and FIG. 8, the runner 420 is further provided with a first limiting groove 421 for accommodating the workpiece, and the bottom wall of the first limiting groove 421 forms the first supporting arc surface 421a. It can be understood that by setting the first limiting groove 421 on the runner 420, the position of the workpiece on the runner 420 can be limited, so as to maintain the consistency of the workpiece in the feeding direction, thereby improving the machining accuracy of the workpiece. In this embodiment, the middle of the runner 420 is recessed to form the first limiting groove 421 . In other embodiments, the runner 420 may be partially raised to form the first limiting groove 421 . Of course, in other embodiments, limit structures such as limit posts may also be provided on the runner 420 to limit the position of the workpiece.

Specifically, the first support arc surface 421 a has a distal end farthest from the rotating shaft 423 and a proximal end closest to the rotating shaft 423 . The width of the first limiting groove 421 gradually decreases along the direction from the distal end to the proximal end of the first supporting arc surface 421a. In this regard, the present embodiment takes an aluminum square pass as an example for explanation. During the rotation of the workpiece, not only the height of the part where the workpiece is in contact with the runner 420 will change, but also the part of the workpiece that is in the first limiting groove 421 The width will also change accordingly. By setting the groove width of the first limiting groove 421 to taper from the distal end to the proximal end of the first supporting arc surface 421a, the actual supporting height of the runner 420 can be adjusted simultaneously during the rotation of the runner 420 And the first limiting groove 421 is used for accommodating the groove width of the workpiece part, so as to support and limit the workpiece in real time and improve the machining accuracy of the workpiece. It can be understood that when the distal end of the first supporting arc surface 421a is in contact with the workpiece, the actual supporting height of the runner 420 reaches the highest level. When the proximal end of the first supporting arc surface 421a is in contact with the workpiece, the actual supporting height of the runner 420 The height is the lowest.

Referring to FIG. 9 and FIG. 10 , in this embodiment, the runner 420 is further provided with a second limiting groove 422 , and the bottom wall of the second limiting groove 422 forms a second supporting arc surface 422 a , the second The width of the limiting slot 422 is gradually reduced along the direction from the distal end to the proximal end of the second supporting arc surface 422 a , and both ends of the second limiting slot 422 communicate with both ends of the first limiting slot 421 respectively. That is, in this embodiment, the wide end of the first limiting slot 421 is communicated with the wide end of the second limiting slot 422 , and the narrow end of the first limiting slot 421 is communicated with the narrow end of the second limiting slot 422 . . It can be understood that by disposing the second limiting slot 422 on the runner 420, and the two ends of the second limiting slot 422 are connected with the first limiting slot 421 respectively, so that when the runner 420 rotates to the second supporting arc surface When the workpiece 422a is in contact with the workpiece, the position of the workpiece can be limited by the second limiting groove 422, thereby increasing the limit on the workpiece. Of course, in terms of the preparation of the runner 420, this design can also reduce the difficulty of preparing the runner 420 and save costs. It should be noted that, in other embodiments of the present application, the groove width of the first limiting groove 421 and/or the second limiting groove 422 may also remain unchanged.

Specifically, please refer to FIGS. 7 to 10 , in the present application, the two side walls of the first limiting groove 421 and/or the second limiting groove 422 are rotated from the outside of the rotating wheel 420 along the rotation axis of the rotating wheel 420 . Lean inward. In this way, the groove width of the first limiting groove 421 and/or the second limiting groove 422 can be maximized, so as to be suitable for processing of more types of workpieces.

Specifically, in the present application, there is a smooth transition between the side wall and the bottom wall of the first limiting groove 421 and/or the second limiting groove 422 . This arrangement can reduce the resistance received by the workpiece when it rotates, thereby facilitating the rotation of the workpiece.

Please continue to refer to FIG. 7 , in this embodiment, the support device 400 further includes a first driving member 430, and the first driving member 430 is used for driving the runner 420 to rotate. It can be understood that, by driving the runner 420 to rotate by the first driving member 430, the adaptive rotation of the runner 420 can be realized, thereby improving the processing efficiency of the workpiece. In addition, the first driving member 430 usually has a self-locking function, which can keep the position of the runner 420 unchanged after rotating a certain angle, so as to limit the workpiece. It should be noted that, in order to realize the self-adaptive adjustment of the runner 420, the first driving member 430 is directly controlled by the control system of the composite machining center for metal parts. The control system can be preset with various parameters of the workpiece, such as length, width and height, and has a built-in algorithm. 421 or the actual width of the second limiting groove 422, and then control the first driving member 430 to drive the runner 420 to rotate according to the actual supporting height. Obviously, the actual support height of the first support arc surface 421a on the runner 420 has a certain corresponding relationship with the groove width of the first limit groove 421, so that the actual support height of the runner 420 can match the workpiece at the first limit. Actual width within bit slot 421. Correspondingly, the actual supporting height of the second supporting arc surface 422a of the runner 420 and the groove width of the second limiting groove 422 also have a corresponding relationship. It should also be noted that, in other embodiments of the present application, the runner 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 connected in a driving manner with the rotating shaft 423 of the runner 420 through the first transmission belt 440 . It can be understood that, as a common first driving member 430, the motor is mature in technology, easy to obtain, and low in cost. The output shaft of the motor and the rotating shaft 423 of the runner 420 are connected by the first transmission belt 440.
