[0002] At present, in the process of workpiece processing, it is generally necessary to clamp the workpiece on the clamping device, and then use the processing tool on the machine tool to process different positions. When the workpiece is irregular, such as an arc-shaped workpiece or a workpiece with inconsistent thickness, different clamping devices are required to clamp in sections, and the spacing between different clamping devices needs to be adjusted according to the size of the workpiece. The existing practice mainly relies on manual implementation, or a separate drive is set on a separate clamping device for adjustment. The movement stroke of a separate clamping device requires a separate drive to control. On the one hand, it wastes the drive structure and has a high cost.

DETAILED DESCRIPTION

[0030] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0031] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] like Figure 1 The CNC machining center with intelligent clamping mechanism shown in FIG. 6 comprises a machine body 10, a machining tool 50, a clamping mechanism and a third driving mechanism 60, and a machining seat 11 and a connecting member 40 are arranged on the machine body 10. The machining tool 50 can be used to process the workpiece on the machining seat 11, and the third driving mechanism 60 can drive the machining seat 11 to move in the Y-axis direction.

[0034] The specific clamping mechanism includes at least two clamping components 20, a first driving mechanism 30 and a second driving mechanism 13. A processing seat 11 and a connecting piece 40 are provided on the machine body 10. The at least two clamping components 20 are installed on the processing seat 11, and each clamping component 20 can move relative to the processing seat 11 along the X-axis direction, that is, the distance between two adjacent clamping components 20 can be adjusted.

[0035] Specifically, the first driving mechanism 30 is used to drive the processing seat 11 to move along the X-axis direction, and the second driving mechanism 13 is used to drive the connecting member 40 to move along the Z-axis direction to move closer to or away from the processing seat 11, and after the connecting member 40 moves closer to the processing seat 11, the connecting member 40 can be connected to one of the clamping assemblies 20. In addition, the second driving mechanism 13 can drive the clamping assembly 20 to move along the Z-axis direction after the clamping assembly 20 is connected to the connecting member 40.

[0036] On the basis of the above structure, when using the CNC machining center with an intelligent clamping mechanism of the present invention, the workpiece can be placed on at least two groups of clamping assemblies 20 on the processing seat 11, and each clamping assembly 20 can clamp the workpiece at different positions. In order to make the two adjacent clamping assemblies 20 adapt to the structure of different positions of the workpiece, the second driving mechanism 13 can drive the connecting member 40 to move downward in the Z-axis direction, and the connecting member 40 can be connected to a clamping assembly 20 on the processing seat 11. Thereafter, the first driving mechanism 30 drives the processing seat 11 to move, and the clamping assembly 20 connected to the connecting member 40 can be restricted to move relative to the processing seat 11 when the processing seat 11 moves in the X-axis direction, and other adjacent clamping assemblies 20 can move with the processing seat 11. In this way, the spacing between the two adjacent clamping assemblies 20 can be adjusted, and the clamping assembly 20 can clamp different positions of the workpiece.

[0037] In addition, when the clamping assembly 20 clamps the workpiece at different heights, after the second driving mechanism 13 drives the connecting member 40 to connect with the clamping assembly 20, the connecting member 40 moves under the drive of the second driving mechanism 13 to drive the clamping assembly 20 to move up and down. The clamping assembly 20 clamps the workpiece at different heights, which is suitable for clamping irregular workpieces.

[0038] After the workpiece is clamped by each set of clamping assemblies 20, the second driving mechanism 13 can drive the connecting member 40 to move upward, and the connecting member 40 is released from the clamping assembly 20. The second driving mechanism 13 can drive the machining tool 50 to move to a suitable height, and the machining tool 50 can perform machining.

[0039] Of course, after the connecting member 40 is disengaged from the clamping assembly 20, the first driving mechanism 30 can drive the processing seat 11 to move as a whole along the X-axis direction, that is, the workpiece on the processing seat 11 can move left and right, and the third driving mechanism 60 can drive the processing seat 11 to move as a whole along the Y-axis direction, that is, the workpiece on the processing seat 11 can move forward and backward. In this way, the workpiece moves left and right and forward and backward, and the up and down movement of the processing tool 50 can be used to perform processing at different positions of the workpiece.

[0040] It should be noted that when adjusting the position of the clamping assembly 20 in the X-axis direction, the connecting member 40 is connected to different clamping assemblies 20, and the first driving mechanism 30 drives the processing seat 11 to move a certain displacement, so that the interval between two adjacent clamping assemblies 20 can be controlled. The connecting member 40 is connected to different clamping assemblies 20, and the first driving mechanism 30 is started, so that different clamping assemblies 20 can be driven to move. Similarly, when adjusting the position in the Z-axis direction, the connecting member 40 moves with different clamping assemblies 20, and the second driving mechanism 13 drives the connecting member 40 to move to different heights, that is, when controlling the stroke, it is only necessary to control the movement stroke of the first driving mechanism 30 or the second driving mechanism 13, which is convenient for centralized control, and there is no need to set up a separate drive, saving resources.

[0041] Furthermore, a connecting arm 12 is provided at the power output end of the second drive mechanism 13, and the above-mentioned connecting member 40 and the processing tool 50 are installed on the connecting arm 12. In this way, the connecting member 40 and the processing tool 50 can be connected to the power output end of the second drive mechanism 13 with the connecting arm 12 as the installation basis, and the disassembly direction, and the connecting member 40, the processing tool 50 are not directly connected to the power output end of the second drive mechanism 13, thereby preventing the vibration of the second drive mechanism 13 during operation from affecting the connecting member 40 or the processing tool 50.

[0042] Furthermore, a fourth driving mechanism may be provided on the connecting arm 12, and the fourth driving mechanism may drive the processing tool 50 to rotate around the Z axis, the Y axis and the X axis respectively. That is to say, the processing tool 50 is installed on the connecting arm 12, and driven by the fourth driving mechanism, the processing tool 50 has three degrees of rotational freedom, which facilitates the processing tool 50 to perform multi-angle processing on the workpiece.

[0043] More specifically, in this embodiment, see Figure 6 The fourth driving mechanism includes a first rotating motor, a second rotating motor 14 and a third rotating motor 15, wherein the rotating shaft of the first rotating motor extends along the X-axis direction, and the rotating shaft of the first rotating motor is connected to the body 10 of the second rotating motor 14. It should be noted that the rotating shaft of the first rotating motor and the body 10 of the second rotating motor 14 can be synchronously connected through a synchronous belt transmission mechanism.

[0044] In addition, the rotating shaft of the second rotating motor 14 extends along the Z-axis direction, connecting the body 10 of the third rotating motor 15 with the body 10 of the second rotating motor 14, and the rotating shaft of the third rotating motor 15 extends along the Y-axis direction; the rotating shafts of the second rotating motor 14 and the third rotating motor 15 are both connected to a processing tool 50.

[0045] In this way, the shaft of the first rotating motor can drive the processing tool 50 of the second rotating motor 14 or the third rotating motor 15 to rotate around the X-axis, and the shaft rotation of the second rotating motor 14 can drive the corresponding processing tool 50 to rotate around the Z-axis, and the shaft rotation of the third rotating motor 15 can drive the corresponding processing tool 50 to rotate around the Y-axis. Of course, the processing tool 50 connected to the second rotating motor 14 and the processing tool 50 connected to the third rotating motor 15 can be the same or different, and the specific selection is based on actual processing needs.

[0046] Further, a fourth rotary motor 16 is provided at the power output end of the second driving mechanism 13. Specifically, a connecting seat is provided at the power output end of the second driving mechanism 13, and the fourth rotary motor 16 is mounted on the fourth rotary motor 16. The rotating shaft of the fourth rotary motor 16 extends along the Z-axis direction, and the connecting arm 12 is synchronously connected with the rotating shaft of the fourth rotary motor 16. That is, the fourth rotary motor 16 can drive the connecting arm 12 to rotate as a whole, and the connecting member 40 connected to the connecting arm 12 can rotate around the Z-axis.

[0047] On the one hand, the connecting member 40 can be in a connected state when it is rotated at a certain angle. After the second driving mechanism 13 drives the connecting arm 12 to move downward, the connecting member 40 can be directly connected to the clamping assembly 20. After the connecting member 40 rotates to another angle, the connecting member 40 can be in a non-connected state, that is, after the second driving mechanism 13 drives the connecting arm 12 to move relative to each other, the connecting member 40 and the clamping assembly 20 are offset and cannot be connected. At this time, the processing tool 50 is working.

[0048] On the other hand, the rotation of the connecting member 40 can also make the connecting member 40 connect to the clamping seat 21 at different angles, which is suitable for connecting at different positions of the clamping seat 21, and the connection is more flexible. In addition, the overall rotation of the connecting arm 12 can also drive the processing tool 50 to rotate around the Z axis in a larger range.

[0049] Furthermore, the clamping assembly 20 in this embodiment includes a clamping seat 21, a first clamping member 22, a second clamping member 23, a first driving member 24 and a second driving member 25. The first driving member 24 is installed on the processing seat 11, and the first clamping member 22, the second clamping member 23 and the second driving member 25 are all installed on the clamping seat 21, and the first clamping member 22 and the second clamping member 23 are spaced apart in the Z-axis direction. Specifically, the first driving member 24 is used to drive the clamping seat 21 to move along the Z-axis direction, and the second driving member 25 can drive the first clamping member 22 to move along the Z-axis direction.

[0050] Specifically, when the clamping assembly 20 is adjusted in the Z-axis direction, the connecting member 40 moves downward under the drive of the second driving mechanism 13, and the connecting member 40 can be connected to the clamping seat 21. After that, the first driving member 24 can drive the second clamping seat 21 to move up and down. At the same time, the second driving mechanism 13 and the first driving member 24 work synchronously, and the up and down movement of the clamping seat 21 can be synchronized and controlled by the second driving mechanism 13, so that the height position of the clamping seat 21 on the processing seat 11 can be adjusted. When performing the clamping operation, the workpiece can be placed between the first clamping member 22 and the second clamping member 23, and the second driving member 25 drives the first clamping member 22 to move up and down, so as to achieve the clamping or loosening of the workpiece.

[0051] Furthermore, a first slide rail 111 and at least two slide seats 113 may be provided on the processing seat 11, so that the first slide rail 111 extends along the X-axis direction, the slide seat 113 and the first slide rail 111 are slidably matched, and the first driving member 24 of each clamping assembly 20 and the clamping seat 21 are correspondingly installed on each slide seat 113; the clamping seat 21 and the slide seat 113 are slidably matched and can slide along the Z-axis direction. Based on this structure, when the first driving mechanism 30 drives the processing seat 11 to move in the X-axis direction, the slide seat 113 can be restricted by the connecting member 40, and the slide seat 113 can move along the first slide rail 111, guiding the slide seat 113 to move stably in the X-axis direction, preventing movement deviation during the movement of the clamping assembly 20, and stabilizing the workpiece clamping operation.

[0052] Similarly, a second slide rail 114 may be provided on the slide seat 113, and the second slide rail 114 extends along the Z-axis direction; a slider is provided on the corresponding clamping seat 21, and the slider cooperates with the second slide rail 114. In this way, when the clamping assembly 20 moves in the Z-axis direction, the slider of the clamping seat 21 slides and cooperates with the second slide rail 114, and the clamping seat 21 moves up and down.

[0053] Furthermore, a first clamping switch 112 is provided on the clamping seat 21, and the first clamping switch 112 can release or lock the second slide rail 114, so that the clamping seat 21 moves or is fixed along the second slide rail 114. That is, when the position of the clamping assembly 20 in the Z-axis direction is adjusted, the first clamping switch 112 can release the second slide rail 114, and the clamping seat 21 can have the freedom to move up and down relative to the slide 113. At this time, the clamping seat 21 can be driven by the second driving mechanism 13 and the first driving member 24 to adjust the position in the Z-axis direction. After the position in the Z-axis direction is adjusted, the first clamping switch 112 can clamp the second slide rail 114, so that the clamping seat 21 and the second slide rail 114 are relatively fixed, preventing the workpiece from moving downward due to the force applied by the processing tool 50 during the processing, so that the processing process is more stable.

[0054] Similarly, the slide 113 is provided with a second clamping switch 26, which is used to clamp or release the first slide rail 111, so that the slide 113 moves or is fixed along the first slide rail 111. That is, when adjusting the position of the clamping assembly 20 in the X-axis direction, the second clamping switch 26 can release the first slide rail 111, and the slide 113 can have the freedom of movement in the X-axis direction with the first slide rail 111. During the movement of the processing seat 11 in the X-axis direction, the slide 113 can move relative to the first slide rail 111, and the clamping assembly 20 can adjust the position in the X-axis direction. After the position of the clamping assembly 20 in the X-axis direction is fixed, the second clamping switch 26 can clamp the first slide rail 111 to prevent the clamping assembly 20 from shifting during the processing process.

[0055] It should be noted that the first clamping switch 112 and the second clamping switch 26 in this embodiment can be selected as electromagnetic switches in the prior art. When the power is on, the electromagnet extends to clamp, and when the power is off, the electromagnet releases, which is convenient for control. Of course, the first clamping switch 112 and the second clamping switch 26 can also be selected as other components with clamping or releasing functions (such as pneumatic fingers, etc.) in the prior art.

[0056] Furthermore, the first driving member 24 and the second driving member 25 can both be selected as driving cylinders, and the piston rod of the driving cylinder can be extended or retracted. The first driving member 24 is a driving cylinder, and the driving cylinder uses gas to achieve the extension or retraction of the piston rod, which is straight up and down, so as to facilitate the up and down coordination with the first driving mechanism 30.

[0057] Furthermore, the connecting member 40 in this embodiment includes a hook, see Figure 2 After the second driving mechanism 13 drives the hook to move downward, the hook is engaged with the clamping assembly 20, and the connection is more convenient.

[0058] Of course, the connecting member 40 can also be an electromagnet. After the second driving mechanism 13 drives the connecting member 40 to move downward, the electromagnet is powered on to be magnetically connected to the clamping seat 21, and when it is released, the electromagnet is powered off. In other cases, the connecting member 40 can also be implemented by a clamp in the prior art.

[0059] Furthermore, the above-mentioned first driving mechanism 30 includes a first motor, a first screw rod, a first nut and a first guide mechanism. The first motor is installed on the machine body 10, and the first screw rod extends along the X-axis direction; the first screw rod is synchronously connected to the rotating shaft of the first motor, and the first nut is threadedly mounted outside the first screw rod. The first guide mechanism is used to guide the first nut to move along the first screw rod when the first nut rotates; the processing seat 11 is connected to the first nut.

[0060] When driving the processing seat 11 to move in the X-axis direction, the shaft of the first motor rotates, driving the first screw to rotate, and the rotation of the first screw can drive the first nut to rotate. The rotational movement of the first nut can be converted into movement along the extension direction of the first screw under the guidance of the first guide mechanism, which can drive the processing seat 11 connected to the first nut to move in the X-axis direction.

[0061] Of course, the third driving mechanism 60 in this embodiment also includes a third motor, a third screw rod, a third nut and a third guide mechanism. The third motor is installed on the body 10, and the third screw rod extends along the Z-axis direction; the third screw rod is synchronously connected to the rotating shaft of the third motor, and the third nut is threadedly mounted outside the third screw rod; the third guide mechanism is used to guide the third nut to move along the third screw rod when the third nut rotates; a mounting seat is provided on the third nut, and the above-mentioned first driving mechanism 30 and the processing seat 11 are both installed on the mounting seat.

[0062] In this way, the rotation of the shaft of the third motor can drive the third screw to rotate, and the rotation of the third screw can drive the third nut to rotate. The rotational movement of the third nut is limited by the third guide mechanism, thereby guiding the third nut to move in the Y-axis direction, and then the processing seat 11 on the mounting seat and the first driving mechanism 30 are linked accordingly.

[0063] Similarly, the second driving mechanism 13 includes a second motor, a second screw rod, a second nut and a second guide mechanism. The second motor is installed on the body 10, and the second screw rod extends along the Z-axis direction; the second screw rod is synchronously connected to the rotating shaft of the second motor, and the second nut is threadedly mounted outside the second screw rod; the second guide mechanism is used to guide the second nut to move along the second screw rod when the second nut rotates; the connecting piece 40 is connected to the second nut through the connecting arm 12.

[0064] When the driving connecting member 40 moves in the Z-axis direction, the shaft of the second motor rotates, driving the second screw to rotate, and the rotation of the second screw can drive the second nut to rotate. The rotational movement of the second nut can be converted into movement along the extension direction of the second screw under the guidance of the second guide mechanism, which can drive the connecting arm 12 connected to the second nut to move in the Z-axis direction, and then drive the connecting member 40 to move in the Z-axis direction.

[0065] It should be noted that the first drive mechanism 30 and the second drive mechanism 13 are both implemented by a screw transmission mechanism. The screw and the nut are matched through threads with high precision, and are driven by a motor, which is convenient for electric control. The corresponding stroke control can be achieved by directly setting the motor speed and number of rotations in the controller.

[0066] Of course, the first driving mechanism 30 and the second driving mechanism 13 can also be selected as cylinders, and the piston rods of the cylinders are controlled by the amount of gas, so the intake amount can be controlled.

[0067] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
