An electric push rod 6 is fixedly connected to the top of the fixing block 4, and the output shaft of the electric push rod 6 is fixedly connected to the top right side of the lifting platform 5. Linear guide rails 7 are fixedly connected to both ends of the front of the column 3, and the two ends of the back of the lifting platform 5 slide against the linear guide rails 7. The grinding mechanism includes a grinding mechanism fixedly connected to the top left side of the lifting platform 5. Motor 2 8, the output shaft of which is detachably connected to grinding head 9 via a quick connector; an X-axis moving mechanism is provided between column 3 and chip baffle 2, the X-axis moving mechanism includes shaft bracket 10 symmetrically fixedly connected to both ends of the back of chip baffle 2, and platform 11 slidably connected to the upper end face of chip baffle 2, with slider 12 fixedly connected to both ends of the bottom front of platform 11, and screw 13 rotatably connected between the two shaft brackets 10 via bearings, the middle of the two sliders 12 having a threaded groove that engages with screw 13, motor 14 fixedly connected to the outside of the right shaft bracket 10, the output shaft of motor 14 fixedly connected to screw 13, and the middle of the top right side of platform 11 fixedly connected to... A fixing block 15 is attached, and an electric push rod 16 is fixedly connected to the back of the fixing block 15. The output shaft of the electric push rod 16 is fixedly connected to the outside of the right bottom end of the column 3. A dovetail groove 17 is opened in the middle of the top of the platform 11, and a dovetail slider 18 that slides in cooperation with the dovetail groove 17 is fixedly connected to the middle of the bottom end of the column 3. A clamping mechanism is provided on the side of the grinding table 1 away from the chip baffle 2. The clamping mechanism includes a shaft frame 19 symmetrically fixedly connected to the two ends of the left side of the grinding table 1, and a sliding frame 20 symmetrically arranged on both sides of the top of the grinding table 1. A bidirectional lead screw 21 is rotatably connected between the two shaft frames 19 through bearings. A slider 22 is fixedly connected to the bottom left side of the sliding frame 20. The middle of the slider 22 is provided with a threaded groove that engages with the threaded double lead screw 21. The external of the right shaft bracket 29 is fixedly connected with a knob 23. The clamping mechanism also includes a clamping plate 24 movably disposed below the sliding frame 20, and guide rods 25 symmetrically fixedly connected to both sides of the top of the clamping plate 24. Both ends of the sliding frame 20 are provided with movable holes 26 that engage with the guide rods 25. The middle of the sliding frame 20 is threadedly connected with a knob 27. The output shaft of the knob 27 is rotatably connected to the top middle of the clamping plate 24 through a bearing. A PLC 28 is fixedly connected at the upper right corner of the column 3. The PLC 28 is electrically connected to motor 1, motor 2, electric push rod 1, and electric push rod 2.

[0027] In this embodiment, the use of the bidirectional lead screw 21 and the sliding frame 20 in the clamping mechanism, as well as the linkage design of the knob 27 and the clamping plate 24, enables the rapid adjustment and stable fixation of the workpiece clamping, effectively solving the problem of the workpiece easily generating micro-displacement during the processing in the prior art, and ensuring the accuracy and surface quality of the grinding process.

[0028] Furthermore, through the transmission cooperation between the screw 13 and the slider 12 in the X-axis moving mechanism, and the synergistic effect between the electric push rod 6 and the linear guide rail 7 in the Z-axis moving mechanism, high-precision positioning and stable operation of the grinding mechanism are achieved, solving the problem of insufficient positioning accuracy in the prior art and improving the consistency and reliability of processing accuracy.

[0029] Working principle: The clamping mechanism on the grinding table 1 drives the bidirectional lead screw 21 to rotate by rotating knob 23, causing the sliders 22 on both sides to move the sliding frame 20 along the grinding table 1 in opposite directions, thereby adjusting the clamping distance. After the workpiece is placed on the grinding table 1, tightening knob 27 pushes the clamping plate 24 down along the guide rod 25 to clamp the workpiece. The X-axis moving mechanism drives the screw 13 to rotate by motor 14, causing the slider 12 to move the platform 11 horizontally along the chip baffle 2. At the same time, the electric push rod 16 pushes the column. The dovetail slider 18 at the bottom slides within the dovetail groove 17 of the platform 11, achieving precise lateral positioning of the grinding mechanism. The Z-axis moving mechanism pushes the lifting platform 5 vertically along the linear guide rail 7 via the electric push rod 6, driving the motor 8 and grinding head 9 to adjust their height. After the motor 8 starts, it drives the grinding head 9 to rotate via a quick connector to grind the end face of the workpiece. The chip baffle 2 blocks the grinding debris. By coordinating the actions of the X-axis and Z-axis moving mechanisms with the clamping mechanism, the workpiece clamping, positioning, and fully automatic end face grinding operation are completed.

[0030] In the specific implementation of this technical solution, the PLC can be configured with conventional industrial control systems in the existing technology. Although this type of PLC control method is not described in detail in the technical solution, it is a control method that can be conventionally selected by those skilled in the art according to actual automation needs, and does not affect the implementation of the core innovation of this solution. In practical applications, the PLC is mainly used to coordinate the linkage control of electric actuator 16, electric actuator 26, motor 14, and motor 28, but its specific model and communication interface (such as RS485, Ethernet, or PROFINET) can be adjusted according to the production line requirements, all of which are reasonable extensions of this technical solution.

[0031] It should be further noted that the bidirectional lead screw 21 described in this technical solution can be equipped with a telescopic dust cover (not shown in the figure) according to the actual usage environment. This dust cover can adopt a conventional corrugated or folded structure as used in the prior art to prevent debris and dust generated during grinding from entering the lead screw transmission system. Although this type of dustproof device is not described in detail in the technical solution, it is a protective component that can be conventionally selected by those skilled in the art based on actual working conditions. Its specific materials and installation methods follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the dust cover is mainly used to protect the transmission accuracy and service life of the bidirectional lead screw 21, but its specific structural form can be adjusted according to the requirements of the site environment, all of which fall within the reasonable extension range of this technical solution.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
