[0002] In the field of machining, surface grinders, as key equipment for achieving precision machining of workpiece surfaces, are widely used in industries such as mold manufacturing and precision parts processing. Traditional surface grinders, when machining workpieces requiring double-sided machining, require operators to remove the workpiece from the grinder, flip it over, and then re-clamp it. Because some workpieces are large and heavy, this process of disassembly, flipping, and re-clamping consumes a significant amount of time, severely impacting machining efficiency. Furthermore, traditional table rotation often uses worm gear drives, which suffer from low transmission efficiency and high maintenance costs. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] A CNC horizontal spindle rotary table surface grinder is a precision machining equipment based on CNC technology, mainly used for grinding the surface of workpieces. The "horizontal spindle" in its name refers to the horizontal arrangement of the grinding wheel spindle, and the "rotary table" refers to the circular table on which the workpiece is mounted and rotates to achieve feed motion.

[0025] Due to the technical shortcomings of existing technologies, such as low efficiency in double-sided workpiece processing, please refer to... Figures 1-5This embodiment provides a CNC horizontal spindle rotary table surface grinder that enables automatic workpiece flipping during processing and uses an electromagnetic chuck 7 to fix the workpiece. The entire double-sided workpiece processing requires no manual intervention, thus improving production efficiency. The grinder includes a bed 1, on which a linear motion module 2 is mounted. A slide 3 is fixedly connected to the linear motion module 2. The bottom of the slide 3 is slidably mounted on the bed 1 via two sets of guide rails 4. A support base 5 is fixedly connected to the slide 3, and a rotary drive mechanism 6 is installed inside the support base 5. The rotary drive mechanism 6 is connected to the electromagnetic chuck 7. A column 11 is mounted on the side wall of the bed 1, and a lifting mechanism is installed on the inner side of the column 11. The lowering motion module 12 has a slide plate 13 fixedly connected to it. The inner wall of the slide plate 13 is slidably mounted on the column 11 via multiple sets of guide rails 14. A grinding head assembly 15 is installed on the side wall of the slide plate 13. A workpiece adjustment mechanism 16 is installed on the side wall of the bed 1 near the column 11. The linear motion module 2 controls the slide plate 3 to move horizontally, the lowering motion module 12 controls the slide plate 13 to move vertically, and the rotary drive mechanism 6 controls the electromagnetic chuck 7 to rotate, thereby rotating the workpiece. By combining the movements of the above three components, the workpiece can be controlled to approach the grinding head assembly 15 for grinding, which can improve processing accuracy and efficiency.

[0026] Traditional surface grinders, when grinding workpieces on both sides, require significant time for disassembly, flipping, and reclamping due to the large size and weight of some workpieces, severely impacting processing efficiency. To address this issue, the workpiece adjustment mechanism 16 includes a fixed plate 161 mounted on the side wall of the bed 1. Two sets of electric push rods 162 are mounted at the bottom of the fixed plate 161, and a lifting plate 163 is fixedly connected to the telescopic shafts of the two sets of electric push rods 162. A tilting mechanism is mounted at the top of the lifting plate 163. Component 166; Further, the tilting assembly 166 includes an inner rotating ring 1661 rotatably connected to the top of the lifting plate 163. A gear ring 1662 is fixedly provided on the outer wall of the inner rotating ring 1661. A gear 1663 meshes with the bottom of the gear ring 1662. The gear 1663 is fixedly connected to a second motor 1664 mounted on the side wall of the lifting plate 163. A guide frame 1665 is fixedly connected to the inner side wall of the inner rotating ring 1661. A third motor 1666 is mounted on the side wall of the guide frame 1665. A rotating... The rotating disk 1667 has two oblique holes, and a fixing block 1668 is slidably installed in each of the two oblique holes. The two fixing blocks 1668 are respectively fixed to two clamping arms 1669, and the two clamping arms 1669 are respectively slidably connected to both ends of the guide frame 1665. When adjusting the workpiece, the lifting plate 163 is first controlled to move by the electric push rod 162. The lifting plate 163 drives the flipping assembly 166 to approach the workpiece. Then, the motor 1666 works and drives the turntable to rotate. The turntable moves through the oblique holes. The hole and the fixing block 1668 drive the clamping arm 1669 to move, so that the two clamping arms 1669 come closer to each other and clamp the workpiece. After clamping, the electromagnetic chuck 7 loses its magnetic attraction. The electric push rod 162 lifts the workpiece up again. Then the motor 1664 works and the meshing of the gear 1663 and the gear ring 1662 drives the workpiece to rotate until it flips to the other side. Finally, the workpiece is put back on the electromagnetic chuck 7 and the magnetic attraction of the electromagnetic chuck 7 is restored, thus fixing the workpiece.

[0027] The clamping arms 1669 are in direct contact with the workpiece, which can easily cause damage to the workpiece surface during clamping. To address this issue, rubber pads 16691 are fixed at one end of both clamping arms 1669. The rubber pads 16691 disperse the clamping force through elastic deformation, which can protect the surface accuracy of the workpiece.

[0028] During the lifting and lowering process of the electric push rod 162, the lifting plate 163 is prone to shaking due to lateral force, which affects the flipping accuracy. To address this issue, two sets of sliders 164 are fixedly installed on the back of the lifting plate 163, and the two sets of sliders 164 are slidably mounted on two sets of slide rails 165. Both sets of slide rails 165 are installed on the side wall of the fixed plate 161. The sliders 164 and slide rails 165 cooperate to provide rigid guidance, counteract the lateral force when the electric push rod 162 is lifted and lowered, ensure the vertical movement of the flipping component 166, and improve the stability and positioning accuracy of the flipping process.

[0029] Traditional table rotation often uses worm gear drives, which have low transmission efficiency and high maintenance costs. To address this issue, the rotary drive mechanism 6 includes a motor 601 mounted on a support base 5. A drive wheel 602 is fixed on the output shaft of the motor 601. A driven wheel 604 is connected to one side of the drive wheel 602 via a belt 603. The driven wheel 604 is fixed to the bottom of the electromagnetic chuck 7. The electromagnetic chuck 7 is rotatably connected to the support base 5 via a rotating shaft 605. The motor 601 drives the electromagnetic chuck 7 to rotate via the belt 603. The speed can be adjusted in real time by a CNC system to adapt to the feed speed requirements of different materials and grinding processes. Moreover, the belt 603 drive is quieter than the gear 1663 drive and does not require frequent lubrication, reducing maintenance costs and making it suitable for long-term continuous processing.

[0030] Traditional grinding machines suffer from difficulties in dressing grinding wheels, which are prone to damage or deformation after prolonged use, affecting subsequent grinding accuracy. Furthermore, tool setting relies on manual visual inspection or gauge blocks, resulting in low efficiency and significant errors. To address this issue, a bracket 8 is fixed to the side wall of the support base 5. A diamond pen 9 and a tool setting device are mounted on the top of the bracket 8. The diamond pen 9 is fixed to the bracket 8, and the grinding wheel is controlled by a CNC program to approach and contact the diamond pen 9, allowing for real-time correction of worn areas and ensuring grinding profile accuracy. The tool setting device is directly installed near the machining area. Before machining, the tool setting device approaches the low-speed rotating grinding wheel, and by detecting changes in contact or light signals, it accurately measures the initial position of the grinding wheel, achieving precise grinding operations.
