The utility model provides a numerical control machining center.
In the embodiment of the present invention, as shown in fig. 1 to 4, the numerical control machining center includes a machine table 100, a machining apparatus 200, a machine base 300, and a fixture 400. The metal plate protection plate 110 is disposed around the machine platform 100 to protect workers and prevent the machining of the workpiece 600 from being interfered by external factors. The processing equipment 200 and the machine base 300 are both disposed on the machine base 100, and the processing equipment 200 is used for processing the workpiece 600. The clamping apparatus 400 includes a bridge plate 410 and a clamping assembly 420, wherein the bridge plate 410 is rotatably disposed on the machine base 300, and the clamping assembly 420 is disposed on the bridge plate 410 for clamping the workpiece 600.
It can be understood that, when a workpiece is machined in an existing numerical control machining center, the workpiece is usually fixed on a machine table through a clamp, and then the workpiece is machined from different angles through the movement of machining equipment. Because the moving range and the degree of freedom of the processing equipment are limited, the processing equipment cannot move to each position of the workpiece to process the workpiece, and the processing range of the processing equipment and the types of the processed workpieces are limited. In view of the above problems, the numerical control machining center according to the present application provides that the clamping assembly 420 is disposed on the bridge plate 410 to clamp the workpiece 600, and the bridge plate 410 is rotatably mounted on the base 300, so that when the machining apparatus 200 machines the workpiece 600, the workpiece 600 can be machined in multiple angles, multiple directions, and multiple modes by rotating the bridge plate 410 and matching with the movement of the machining apparatus 200, thereby widening the machining range of the machining apparatus 200. Therefore, compared with the existing numerical control machining center for fixing the workpiece 600, the numerical control machining center has the advantages of wide machining range and high machining applicability.
Further, in this embodiment, the nc machining center further includes a driving motor 500, and the driving motor 500 is disposed on the base 300 and is used for driving the bridge plate 410 to rotate. It can be understood that the driving motor 500 is electrically connected with a control system of the numerical control machining center, and is matched with the movement of the machining equipment 200 through appropriate program control, so that the machining of the workpiece 600 can be completed more efficiently and accurately, and the automation level of the numerical control machining center is greatly improved. Of course, in some embodiments of the present application, the bridge plate 410 may also be manually controlled to rotate by a worker. For example, a worker may drive the bridge plate 410 to rotate by manually controlling the controller of the driving motor 500; the bridge plate 410 can also be driven to rotate directly through the adapter of the rotating wheel.
Preferably, in the present embodiment, the driving motor 500 drives the bridge plate 410 to rotate through a reduction transmission mechanism. It can be understood that the driving motor 500 drives the bridge plate 410 through the reduction transmission mechanism, which not only can increase the torque of the driving motor 500 to reduce the requirement on the driving motor 500; and the minimum rotation angle of the bridge plate 410 can be reduced, i.e., the rotation accuracy of the bridge plate 410 can be improved, to improve the processing accuracy of the workpiece 600. Illustratively, the reduction drive mechanism is a gear reduction drive mechanism. Of course, in other embodiments of the present application, the driving motor 500 may drive the bridge plate 410 to rotate through a transmission mechanism such as a chain transmission mechanism, a belt transmission mechanism, or the like, or the driving motor 500 may be directly connected to a rotating shaft of the bridge plate 410 to drive the bridge plate 410 to rotate.
Optionally, in this embodiment, the processing tool 200 is a CNC processing tool. In other embodiments, the processing tool 200 may also be a laser processing tool or the like.
Further, in another embodiment of the present application, the bridge plate 410 is provided with a machining opening, and the machining opening is arranged to avoid a tool bit of the machining device 200. It will be appreciated that because the clamp assembly 420 clamps the workpiece 600 to the bridge plate 410, the bridge plate 410 may form a stop on one side of the workpiece 600, limiting the machining of the workpiece 600 by the machining apparatus 200. With the side of the workpiece 600 facing the bridge plate 410 being the backside of the workpiece 600, typically, the backside of the workpiece 600 does not need to be processed, but the backside of some special workpieces 600 is. Therefore, the avoidance port is formed in the bridge plate 410, so that the tool bit of the machining equipment 200 can be adapted to the back side of the workpiece 600, and the machining range of the numerical control machining center is widened. In this embodiment, the bridge plate 410 is not provided with the position-avoiding opening, so that the structural strength of the bridge plate 410 can be improved.
Referring to fig. 4 and 5, in the present embodiment, the clamping assembly 420 includes a first clamping member 421 and a second clamping member 422, the first clamping member 421 is used for clamping the workpiece 600 along a direction parallel to the plate surface of the bridge plate 410, and the second clamping member 422 is used for clamping the workpiece 600 along a direction perpendicular to the plate surface of the bridge plate 410. It can be understood that the clamping assembly 420 achieves the fixation of the workpiece 600 from both the horizontal direction and the vertical direction by clamping the workpiece 600 in the direction parallel to the plate surface of the bridge plate 410 by the first clamping member 421 and clamping the workpiece 600 in the direction perpendicular to the plate surface of the bridge plate 410 by the second clamping member 422, with the plate surface of the bridge plate 410 as a reference. Because in the process of processing the workpiece 600, the bridge plate 410 drives the workpiece 600 to rotate, the workpiece 600 is clamped in the horizontal direction and the vertical direction through the first clamping piece 421 and the second clamping piece 422, the stability of clamping the workpiece 600 can be ensured, the movement of the workpiece 600 is reduced as much as possible, and the processing precision is ensured. Of course, in other embodiments of the present application, the clamping assembly 420 may also include only the first clamping member 421 or the second clamping member 422, i.e., only the workpiece 600 is clamped from a direction parallel to the plate surface of the bridge plate 410, or only the workpiece 600 is clamped from a direction perpendicular to the plate surface of the bridge plate 410.
Specifically, in the present embodiment, the first clamping member 421 includes a first fixing seat 421a, a first driving cylinder 421b, and a first clamping block 421 c.

Obviously, the first driving cylinder 421b can drive the first clamping block 421c to approach and separate from the first fixing seat 421a along a direction parallel to the plate surface of the bridge plate 410. It can be understood that, when the workpiece 600 is clamped, the first driving cylinder 421b first drives the first clamping block 421c to move in a direction away from the first fixing seat 421a, so that a gap for placing the workpiece 600 is reserved between the first clamping block 421c and the first fixing seat 421a, and after the workpiece 600 is placed, the first driving cylinder 421b drives the first clamping block 421c to move in the direction of the first fixing seat 421a until the workpiece 600 is clamped by the first fixing seat 421 a. In the embodiment, the first driving cylinder 421b is selected to drive the first clamping block 421c, so that the structure is simple and the implementation is convenient. The first driving cylinder 421b may be disposed on the first fixing seat 421a in other embodiments. It should be noted that, in other embodiments of the present application, the first clamping block 421c may also be driven to move closer to and away from the first fixing seat 421a by a motor, a hydraulic cylinder, or the like.
Specifically, in the present embodiment, the second clamping member 422 includes a second fixing seat 422a, a corner cylinder 422b and a second clamping block 422 c. The second fixing seat 422a is disposed on the bridge plate 410, the corner cylinder 422b is disposed on the bridge plate 410, and the corner cylinder 422b can drive the second clamping block 422c to fasten the workpiece 600 to the second fixing seat 422a along a direction perpendicular to the plate surface of the bridge plate 410. It can be understood that the corner cylinder 422b is selected to drive the second clamping block 422c to fasten the workpiece 600 to the second fixing seat 422a, and the feature of the corner cylinder 422b can be utilized to enable the second clamping block 422c to rotate a certain angle and be dislocated with the second fixing seat 422a when the workpiece 600 is released by the second clamping block 422c, so as to facilitate the taking and placing of the workpiece 600. The angle cylinder 422b may be disposed on the second fixing seat 422a in other embodiments of the present disclosure. It should be noted that, in other embodiments of the present application, the second clamping block 422c may also be driven to move closer to and away from the second fixing seat 422a by a driving member such as a driving cylinder, a motor, a hydraulic cylinder, or the like.
Preferably, in the present embodiment, the first and second clamping pieces 421 and 422 are alternately arranged along the extending direction of the bridge plate 410. Immediately, a plurality of first holding members 421 and second holding members 422 may be provided on the bridge plate 410 in this way to fix the workpiece 600 at multiple points, thereby improving the stability of the fixture 400 in holding the workpiece 600. Meanwhile, the first clamping pieces 421 and the second clamping pieces 422 are alternately arranged along the extending direction of the bridge plate 410, so that the clamping force of the first clamping pieces 421 and the second clamping pieces 422 can be prevented from being concentrated at a certain position of the workpiece 600, the stress concentration of the workpiece 600 is avoided, and the protection of the workpiece 600 is enhanced.
Further, in this embodiment, the clamping assembly 420 further includes a profile clamping member 423, the profile clamping member 423 is disposed at two ends of the bridge plate 410, and the profile clamping member 423 includes a profile fixing seat 423a, a second driving cylinder 423b, and a profile clamping block 423 c. Wherein the profile modeling fixing base 423a is arranged on the bridge plate 410, the second driving cylinder 423b is arranged on the bridge plate 410 for driving the profile modeling clamping block 423c to approach and depart from the profile modeling fixing base 423a, and the profile modeling fixing base 423a and the profile modeling clamping block 423c are matched with the bending sections at the two ends of the workpiece 600. It can be understood that, because the copying fixing seat 423a and the copying clamping block 423c are matched with the bending sections at the two ends of the workpiece 600, the shape of the workpiece 600 can be matched, the matching tightness between the copying clamping piece 423 and the workpiece 600 is increased, the stability of clamping the workpiece 600 is further improved, and the copying clamping piece 423 is additionally arranged on the bridge plate 410 and can be matched with the first clamping piece 421 and the second clamping piece 422, so that the stability of clamping the workpiece 600 by the fixture 400 is improved. In other embodiments of the present application, the second driving cylinder 423b may be provided in the profile fixing base 423 a.
Specifically, in the present embodiment, the second driving cylinder 423b drives the copying clamp block 423c to approach and separate from the copying fixing seat 423a in a direction perpendicular to the plate surface of the bridge plate 410. Of course, in other embodiments, the second driving cylinder 423b can drive the copying clamp 423c to clamp the workpiece 600 along the direction parallel to the plate surface of the bridge plate 410.
Referring to fig. 4 and 6, in the present embodiment, the fixture 400 further includes a positioning pin 440, and the positioning pin 440 is telescopically disposed on the bridge plate 410 and is used to cooperate with a positioning hole on the workpiece 600 to position the workpiece 600.
