A grinding wheel is fixed at the bottom of the movable structure.

[0009] Cooling structures are fixed on the inner walls of both sides of the protective cover. The cooling structure includes a mounting plate, a threaded rod, a movable block, a mounting block, a coolant pipe, and a second servo motor. The movable blocks are located on both sides of the grinding wheel at the top of the protective cover. The movable blocks are threaded with threaded rods inside. The two ends of the threaded rods are fixed with mounting plates. The movable blocks are fixed with mounting blocks on the side near the grinding wheel. The top of the mounting blocks is interference-fitted with a coolant pipe. The second servo motor is mounted on the outer wall of one side of the mounting plate.

[0010] Furthermore, the movable structure includes a hydraulic rod, a movable seat, a movable groove, a movable block, a lead screw, a guide rod, and a first servo motor. The hydraulic rod is fixed to the inner walls on both sides of the top of the protective cover. The bottom of the hydraulic rod is fixed with a movable seat. The bottom of the movable seat is provided with a movable groove. The movable groove is provided with a movable block. The movable block is internally threaded with a lead screw. Guide rods are provided on both sides of the lead screw. The first servo motor is installed on the outer wall of one end of the movable seat.

[0011] Furthermore, one end of the lead screw extends to the outside of the movable seat and is fixedly connected to the output end of the first servo motor, while the other end of the lead screw extends to the inside of the movable seat and is rotatably connected to the movable seat.

[0012] Furthermore, both ends of the guide rod are fixedly connected to the inner wall of the movable seat, and the guide rod and the movable block are slidably connected.

[0013] Furthermore, one side of the mounting plate is fixedly connected to the inner wall of the protective cover, and one end of the threaded rod extends to the outside of the mounting plate and is fixedly connected to the output end of the second servo motor.

[0017] The present invention provides a compact grinding machine for miniature sliders, the advantages of which are:

[0018] By incorporating a cooling structure, the grinding wheel generates a significant amount of heat during grinding of the slider. At this point, the second servo motor is activated. The rotation of the second servo motor drives the threaded rod to rotate, which in turn drives the movable block to rotate. The movable block, via the mounting block, moves the coolant pipe to the grinding wheel's position, thus reducing the temperature during grinding and preventing workpiece deformation due to excessive heat. This also reduces wear and tear during grinding, thereby improving processing quality and efficiency. This device effectively cools the grinding process, enhancing the working efficiency of this compact miniature slider grinder.

[0019] By setting up a moving structure, the first servo motor is started. The rotation of the first servo motor drives the lead screw to rotate, the rotation of the lead screw drives the moving block to move, and the moving block drives the grinding wheel to move, which facilitates grinding different positions of the workpiece. The hydraulic rod can adjust the grinding height of the grinding wheel, realizing the function of the device to facilitate multi-directional grinding of workpieces, and improving the convenience and work efficiency of the miniature slider compact grinder during use.

[0020] By incorporating a clamping structure, activating the electric push rod causes the clamping plate to move via the connecting plate. The two sets of clamping plates move closer together, clamping the workpiece between them. This enables the device to easily clamp the slider, improving the convenience of using this miniature slider compact grinding machine. Attached Figure Description
