DETAILED DESCRIPTION

[0035] The utility model will be further described below according to the drawings and specific embodiments.

[0036] Depend on Figure 1 As shown, this embodiment discloses a production equipment for cemented carbide machining inserts, including a frame 11. A horizontally arranged turntable 17 capable of automatic and slow rotation is mounted on the frame 11. Eight placement platforms 18 are arranged in a circular array within the turntable 17. The placement platforms 18 can rotate relative to the turntable 17. The turntable 17 has a hollow section to reduce its own weight. A quick-grip clamp 23 is provided on the side of each placement platform 18 away from its center. Figure 2 As shown, the frame 11 has a feeding conveyor belt 12 and a discharging conveyor belt 13 arranged side by side on the side near the placement table 18. Along the circumference of the turntable 17, the frame 11 is arranged in sequence with an automatic feeding and discharging mechanism for automatically feeding and discharging the blade workpiece, an automatic locking mechanism, a detection mechanism for identifying the spatial position of the blade workpiece, a grinding mechanism for processing the surface of the blade workpiece, a polishing mechanism for polishing the surface of the blade workpiece, and an unlocking mechanism 36. The unlocking mechanism 36 can push the rocker arm of the quick-grip 23 to unlock the quick-grip 23. The automatic feeding and discharging mechanism includes a second three-axis drive unit 14 fixed on the frame 11 and a moving frame 15 fixed on the power output end of the second three-axis drive unit 14. The moving frame 15 has several sets of suction cup units 16, which are used to adsorb onto the surface of the blade workpiece.

[0037] The turntable 17 is provided with a driven gear 19 on the back side of the placement platform 18, which is coaxially arranged with the placement platform 18. The frame 11 is provided with two gear drive mechanisms that are respectively matched with the inclined grinding component and the polishing mechanism. The gear drive mechanism includes a gear drive motor 37 fixed on the frame 11 and a drive gear 38 located at the power output end of the gear drive motor 37. The drive gear 38 can mesh with the driven gear 19.

[0038] Depend on Figure 4 As shown, the automatic locking mechanism includes a pressure plate 25 positioned above one of the placement platforms 18, a hook 22 near the side of the quick-grip clamp 23, a pressure plate drive assembly 24 for driving the pressure plate 25 toward the placement platform 18, and a hook 22 drive assembly for driving the hook 22 to move vertically along the axial direction of the placement platform 18 and horizontally along the tangent direction of the outer surface of the placement platform 18. The hook 22 drive assembly includes an X-axis drive unit 20 and a Z-axis drive unit 21. The hook 22 drive assembly is composed of two sets of existing translation cylinders capable of achieving... The dual-axis drive mechanism has its own power output end located in the plane and reciprocates along the X and Z axes. The end face of the pressure plate 25 near the placement table 18 is parallel to the placement table 18. When the blade workpiece is placed in the placement table 18, the end face of the blade workpiece at one axial end is located outside the placement table 18. The pressure plate drive assembly 24 controls the pressure plate 25 to press down the end face of the blade workpiece at one axial end to prevent the blade workpiece from tilting. The hook 22 drive assembly controls the hook 22 to move, thereby pulling down the rocker arm of the quick-hand clamp 23 to clamp the blade workpiece located in the placement table 18.

[0039] The inspection mechanism includes a height detection unit 27 for detecting the height position of the upper surface of the blade workpiece and an outer circle detection unit 26 for detecting the position of the circumferential surface of the blade workpiece.

[0040] Depend on Figure 3 As shown, the grinding mechanism includes a surface grinding assembly for flattening the upper surface of the workpiece and a bevel grinding assembly for chamfering the cutting edge of the workpiece. A detection mechanism identifies the position of the upper surface and the circumferential surface of the workpiece and transmits the data to the surface grinding assembly and the bevel grinding assembly located at the next station, thereby ensuring subsequent grinding accuracy. The surface grinding assembly includes a first three-axis drive unit 28, a first grinding wheel head 29, a first grinding wheel drive motor, and a first grinding wheel 30, all mounted on the frame 11. The first grinding wheel head 29 is located at the power output end of the first three-axis drive unit 28, and the first three-axis drive unit 28 drives the first grinding wheel head 29 along the X-axis, Y-axis, and Z-axis directions. The reciprocating motion is achieved by a first grinding wheel drive motor fixedly mounted on a first grinding wheel frame 29, and a first grinding wheel 30 located at the power output end of the first grinding wheel drive motor. The slant grinding assembly includes a swing assembly 31 mounted on a frame 11, a radial drive assembly 34 located at the power output end of the swing assembly 31, a second grinding wheel frame, a second grinding wheel drive motor, and a second grinding wheel 35 located on the radial drive assembly 34. The swing assembly 31 controls the radial drive assembly 34 to swing along the circumferential direction, and the radial drive assembly 34 controls the second grinding wheel frame to move linearly along the radial direction of the circumferential trajectory. The second grinding wheel drive motor is fixedly mounted on the second grinding wheel frame, and the second grinding wheel 35 is located at the power output end of the second grinding wheel drive motor.

[0041] The unlocking mechanism 36 has the same structure as existing power mechanisms that can control their own power output end to move back and forth in a straight line, such as electric hydraulic push rods, electric lead screw slider modules, etc.

[0042] When the blade workpiece needs to be produced, the second three-axis driving unit 14 drives the moving frame 15 to move above the feeding conveyor belt 12, and then makes the moving frame 15 descend, so that the blade workpiece located on the feeding conveyor belt 12 is adsorbed and fixed by the suction cup unit 16. The second three-axis driving unit 14 makes the moving frame 15 shift to above the placement table 18, and places the blade workpiece in the placement table 18. At this time, the upper surface of the blade workpiece is exposed outside the placement table 18. After the control rotary table 17 slowly rotates through a corresponding angle, the blade workpiece located in the placement table 18 is slowly moved below the pressing plate 25. The pressing plate driving assembly 24 controls the pressing plate 25 to descend, and then presses the upper surface of the blade workpiece. When the pressing plate 25 presses the upper surface of the blade workpiece, the hook claw 22 driving assembly drives the hook claw 22 to translate away from the rocker arm direction of the quick hand clamp 23, so as to avoid the rocker arm of the quick hand clamp 23. Then the hook claw 22 is driven to rise and translate to the rocker arm direction close to the quick hand clamp 23, so as to pull the rocker arm of the quick hand clamp 23 by the hook claw 22. At this time, the hook claw 22 driving assembly drives the hook claw 22 to descend, so that the rocker arm of the quick hand clamp 23 swings downward, so that the quick hand clamp 23 fixes the blade workpiece located in the placement table 18. Thereafter, the rotary table 17 is controlled to rotate slowly, so that the blade workpiece located in the placement table 18 sequentially passes through the detection mechanism, the grinding mechanism and the polishing mechanism to process the blade workpiece with the required shape. The rotary table 17 is controlled to rotate slowly, so that the blade workpiece located in the placement table 18 rotates to the side close to the unlocking mechanism 36. The unlocking mechanism 36 controls the power output end to lift upward, so that the rocker arm of the quick hand clamp 23 swings upward. At this time, the blade workpiece located in the placement table 18 is unfixed. Finally, the second three-axis driving unit 14 transports the produced blade workpiece to the discharging conveyor belt 13 through the moving frame 15 and the suction cup unit 16 for discharging.

[0043] Eight placement tables 18 can place blade workpieces to be sequentially produced, improving production efficiency.
