Description

Technical Field

[0001] This utility model relates to the field of CNC machining center technology, and in particular to a CNC machining center with automatic workpiece detection function. Background Technology

[0002] With the continuous development of modern manufacturing, the requirements for workpiece machining accuracy and quality are becoming increasingly stringent. In many fields, the flatness of workpieces directly affects product performance and quality. To meet these high-precision machining needs, CNC machining centers require more advanced detection functions to monitor and control workpiece flatness in real time.

[0003] However, existing flatness inspection equipment has a single function and cannot adjust the inspection position according to the type and shape of the workpiece. The single-function inspection equipment is only suitable for workpieces of a specific shape. When dealing with different types of workpieces, it is necessary to frequently change the inspection equipment or readjust the parameters, which is not adaptable enough.

[0004] Therefore, there is a need to provide a CNC machining center with automatic workpiece detection function for use. Utility Model Content

The bidirectional electric slide is located in the mounting groove, and the bidirectional electric slide is provided with two moving platforms. The rotating columns are rotatably connected to the moving platforms, and the fixed pneumatic grippers are connected inside the moving platforms.

[0008] A further technical solution is that the clamping end of the fixed pneumatic gripper is higher than the top of the mounting plate; this allows for better gripping of workpieces placed at the bottom of the mounting plate.

[0009] In a further technical solution, the detection and adjustment structure includes a rotating motor, a reducer, and a mounting base. The rotating motor is located on the upper moving end, and the reducer is connected to the rotating motor via a transmission.

[0010] In a further technical solution, the top of the mounting base is provided with a vertical rod, the side wall of the mounting shaft is provided with a locking screw, the mounting shaft is provided with a mounting hole, and the vertical rod is inserted into the mounting hole and fixed by the locking screw.

[0011] A further technical solution is provided, wherein the workpiece inspection structure includes a profilometer, a drive motor, a drive screw, and a moving frame. The drive screw is rotatably connected to the mounting base. The drive motor is located on the side wall of the mounting base, and its main shaft is connected to the drive screw. One end of the moving frame is threadedly connected to the drive screw, and the other end of the moving frame is located outside the mounting base. The profilometer is connected to the bottom position of the moving frame outside the mounting base.

[0013] When inspecting a horizontal workpiece, this utility model uses a drive motor to make the mounting base and the horizontal workpiece horizontal. Then, the lower moving end moves the horizontal workpiece left and right to inspect the flatness of the top of the horizontal workpiece.

[0014] When inspecting curved workpieces, the drive motor can be turned to rotate the drive screw on the mounting base according to the different curvatures of the workpiece. This will cause the moving frame to move from inside the mounting base to the outside, so that the profilometer can be adapted to the curvature of the workpiece. Adjustments can be made according to the different curvatures of the workpiece. Then, the rotating motor will drive the mounting base to rotate, which will cause the profilometer to extend the curvature of the workpiece and rotate to inspect the flatness of the top of the curved workpiece.

[0015] This invention can adjust the detection position according to different workpiece types. This adaptive adjustment mechanism reduces manual calibration time and operational errors, expands the applicability of the equipment, improves detection efficiency and versatility, and saves costs and improves production efficiency for enterprises.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-7 As shown, this utility model provides a CNC machining center with automatic workpiece detection function: A CNC machining center with automatic workpiece detection function includes a CNC machining center 1. The CNC machining center 1 is provided with an upper moving end 11 that moves up and down and a lower moving end 12 that moves left and right and forward and backward. During detection, the upper moving end 11 moves to move the position of the contour gauge 41 downward to above the workpiece, and the lower moving end 12 moves left and right and forward and backward to adjust the position of the workpiece, moving the workpiece to a position below the contour gauge 41. The lower moving end 12 is provided with a workpiece fixing structure 2 for fixing the workpiece. The upper moving end 11 is provided with a detection adjustment structure 3 and a workpiece detection structure 4. The detection adjustment structure 3 is connected to the upper moving end 11 and the upper moving end 11 can drive the detection adjustment structure 3 to move downward. The workpiece detection structure 4 is disposed on the detection adjustment structure 3, and the workpiece detection structure 4 and the detection adjustment structure 3 slide together. Through the sliding cooperation between the detection adjustment structure 3 and the workpiece detection structure 4, real-time detection and adaptive position adjustment during the machining process are realized.

[0027] The workpiece detection structure 4 is used to detect the workpiece contour in real time during the processing and feed the data back to the CNC system.

[0028] In this embodiment, refer to Figure 3 As shown, the workpiece fixing structure 2 includes a mounting plate 21, a bidirectional electric slide 22, two rotating columns 23, and two fixed pneumatic grippers 24. The mounting plate 21 is horizontally connected to the lower moving end 12, and has a horizontally arranged mounting groove. The bidirectional electric slide 22 is located within the mounting groove, and has two moving platforms 25. The rotating columns 23 are rotatably connected to the moving platforms 25, and the fixed pneumatic grippers 24 are connected inside the moving platforms 25. In this embodiment, the clamping end of the fixed pneumatic grippers 24 is higher than the top of the mounting plate 21.

[0029] When fixing a horizontal workpiece, the fixing gripper 24 can rotate within the rotating column 23 to adjust the opening position of the fixing gripper 24 so that the openings of the clamping ends of the two fixing grippers 24 are in a horizontal state. Then, the horizontal workpiece is clamped and fixed by the two fixing grippers 24 to ensure stability when the workpiece is subsequently tested for flatness. The two moving platforms 25 of the bidirectional electric slide 22 can move away from or close to each other to fix horizontal workpieces of different lengths when testing them.

[0030] When fixing an arc-shaped workpiece, the fixing gripper 24 can rotate within the rotating column 23, so that the opening direction of the fixing gripper 24 adapts to the arc-shaped workpiece and is adjusted according to the arc angle of the arc-shaped workpiece. The two fixing grippers 24 fix both sides of the arc surface of the arc-shaped workpiece to ensure stability when the workpiece is subsequently inspected for flatness. The two moving platforms 25 of the bidirectional electric slide 22 can move away from or close to each other, which can fix arc-shaped workpieces of different arc shapes when inspecting them.

[0031] The workpiece fixing structure 2 can be adjusted according to the different types of workpieces to make it suitable for fixing different types of workpieces.

[0032] In this embodiment, the clamping end of the fixed pneumatic gripper 24 is higher than the top of the mounting plate 21, which allows for better gripping of workpieces placed at the bottom of the mounting plate 21.

[0033] In this embodiment, refer to Figure 4 and Figure 5 As shown, the detection and adjustment structure 3 includes a rotating motor 31, a reducer 32, and a mounting base 33. The rotating motor 31 is located on the upper moving end 11. The reducer 32 is connected to the rotating motor 31 through transmission. The main shaft of the reducer 32 is provided with a mounting shaft 36. The mounting base 33 is detachably connected to the mounting shaft 36.

[0034] After the rotating motor 31 rotates, the speed of the drive motor 42 is reduced by the speed reducer 32, which then drives the mounting base 33 to rotate. The rotation of the mounting base 33 will drive the contour instrument 41 to rotate in the arc direction of the arc workpiece to detect the flatness of the arc workpiece.

[0035] In this embodiment, the top of the mounting base 33 is provided with a vertical rod 34, the side wall of the mounting shaft 36 is provided with a locking screw 35, the mounting shaft 36 is provided with a mounting hole, and the vertical rod 34 is inserted into the mounting hole and fixed by the locking screw 35.

[0036] After inspecting the workpiece, the locking screw 35 can be loosened to remove the vertical rod 34 from the mounting hole, so that when the CNC machining center 1 performs other steps on the workpiece, it will not interfere with the subsequent machining steps.

[0037] In this embodiment, refer to Figure 6 As shown, the workpiece inspection structure 4 includes a profilometer 41, a drive motor 42, a drive screw 43, and a moving frame 44. The drive screw 43 is rotatably connected to the mounting base 33. The drive motor 42 is located on the side wall of the mounting base 33, and its main shaft is connected to the drive screw 43. One end of the moving frame 44 is threadedly connected to the drive screw 43, and the other end of the moving frame 44 is located outside the mounting base 33. The profilometer 41 is connected to the bottom of the moving frame 44 outside the mounting base 33. The moving direction of the moving frame 44 extends along the length of the mounting base 33.

[0038] It should be noted that the profilometer 41 is a contact profilometer. Its principle is as follows: a measuring head with a diamond stylus contacts the workpiece surface. As the measuring head moves along the workpiece surface, the stylus moves up and down with the surface's undulations. The minute displacement of the stylus is converted into an electrical signal by a sensor, and after amplification and processing, numerical information of the workpiece surface profile is obtained, which is then used to assess the workpiece's flatness. The profilometer 41 is connected to an external display that shows the workpiece flatness information. The model of the profilometer 41 is: Talysurf series contact profilometer.

[0039] When inspecting a horizontal workpiece, the drive motor 42 operates to make the mounting base 33 and the horizontal workpiece horizontal. Then, the lower moving end 12 drives the horizontal workpiece to move left and right, thereby inspecting the flatness of the top of the horizontal workpiece.

[0040] When inspecting curved workpieces, the drive motor 42 can be turned to drive the drive screw 43 to rotate on the mounting base 33 according to the different curvature of the workpiece. This will cause the moving frame 44 to move from inside the mounting base 33 to the outside. The moving frame 44 moves outward and causes the contour meter 41 to adapt to the curvature of the curved workpiece. Adjustments are made according to the different curvature of the workpiece. Then, the rotating motor 31 drives the mounting base 33 to rotate, which will cause the contour meter 41 to extend the curvature of the curved workpiece and rotate to inspect the flatness of the top of the curved workpiece.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
