[0002] A numerical control lathe is a machine tool that controls the movement of tools and workpieces through a computer program. It can automatically complete various machining operations, such as turning, boring, tapping, etc. The numerical control lathe can perform precise machining according to the pre-input design drawing information, improving production efficiency and machining accuracy. The grinding device of the numerical control lathe is usually a grinding wheel, and the grinding wheel can be precisely rotated and moved on the lathe through the numerical control system to achieve precise grinding and machining of the workpiece.

[0003] Publication No.: CN218746888U, a grinding device for a numerical control lathe, includes a mounting base. The upper surface of the mounting base is provided with an outer sleeve. The lower side inside the outer sleeve is provided with a transmission cavity. The upper wall of the transmission cavity is rotatably connected with a screw rod. The inside of the driving cavity is provided with a driving assembly. The driving assembly is connected with the screw rod. The inside of the outer sleeve is slidably connected with an inner sleeve. The inner wall of the inner sleeve is screwed with the stud. The upper end of the inner sleeve is connected with a cross plate. A transmission mechanism is slidably connected to the cross plate. The lower side of the transmission mechanism is connected with a grinding mechanism. The utility model solves the problem that the existing manual polishing or using a grinding machine for polishing will increase the workpiece processing time.

[0004] To sum up, the grinding device in the prior art CN218746888U solves the problem that the existing manual polishing or using a grinding machine for polishing will increase the workpiece processing time. During the grinding process, some debris generated by the workpiece will adhere to the surface of the workpiece, and this grinding device cannot clean the surface of the workpiece, resulting in that after the grinding is completed, the staff needs to manually process the debris, increasing the workload. Content of the Utility Model

[0005] The purpose of the utility model is to provide a grinding device for a numerical control lathe, which has the advantages of sweeping away the debris generated by grinding on the surface of the workpiece while grinding the workpiece, reducing the cleaning workload of the staff, and solving the problem that the grinding device cannot process the debris adhering to the surface of the workpiece during grinding.

[0006] To achieve the above object, the utility model provides the following technical solution: A grinding device for a numerical control lathe, including a fixed frame and a screw sleeve. A hydraulic cylinder is installed at the top end inside the fixed frame, and a cage is installed at the bottom of the hydraulic cylinder. Bearings are embedded on both sides of the cage. The inner rings of the two bearings are fixedly installed with a lead screw, and the screw sleeve is meshed with the lead screw. A grinding machine is installed at the bottom of the screw sleeve. Two springs are welded to the bottom of the screw sleeve on one side of the grinding machine, and a brush plate is installed at the bottom of the two springs. A bearing plate is welded to the inner side of the fixed frame below the screw sleeve.

[0007] When using a grinding device for a numerical control lathe in this technical solution, through the fixing holes of the fixed frame, tools such as bolts are used to fix the fixed frame on the bearing structure. The workpiece to be ground is placed on the top of the bearing plate. Two cylinders push two clamping plates to clamp and fix the workpiece. The hydraulic cylinder drives the cage to descend, so that the grinding machine below the cage contacts the surface of the workpiece. The grinding machine grinds the workpiece. The servo motor drives the lead screw to rotate through the transmission structure. The screw sleeve moves on the rotating lead screw, and the screw sleeve drives the grinding machine to move horizontally to grind the workpiece. The screw sleeve drives the brush plate to move horizontally through two springs, and the brush plate sweeps the surface of the workpiece under the influence of the elastic force of the two springs, sweeping away the debris generated by grinding on the surface of the workpiece.

[0008] Preferably, two movable rods are welded to the top of the cage, and two movable holes are symmetrically opened at the top of the fixed frame. The top ends of the two movable rods pass through the two movable holes. The two movable rods limit the cage. When the cage moves up and down, the two movable rods move in the two movable holes, preventing the cage from shaking.

[0009] Preferably, a servo motor is installed on the side of the cage, and the transmission structure of the servo motor is fixedly connected to the lead screw. The servo motor drives the lead screw to rotate through the transmission structure.

[0010] Preferably, a slider is installed on the top of the screw sleeve, and a chute is opened at the top end inside the cage. The slider and the chute are slidably connected. The slider limits the screw sleeve. When the screw sleeve moves on the lead screw, the slider slides in the chute, preventing the screw sleeve from rotating.

[0011] Preferably, fixing plates one are welded to the front and rear sides of the brush plate, positioning rods are welded to the tops of the two fixing plates one, fixing plates two are welded to the front and rear sides of the screw sleeve, positioning holes are opened in the two fixing plates two, and the top ends of the two positioning rods respectively pass through the two positioning holes. The two positioning rods limit the brush plate. When the brush plate moves up and down, the two positioning rods move in the positioning holes of the two fixing plates two, restricting the moving direction of the brush plate.

[0012] Preferably, stoppers are welded to the top ends of the two positioning rods, and the outer diameters of the two stoppers are larger than the inner diameters of the two positioning holes. The two stoppers prevent the two positioning rods from slipping out of the two positioning holes.

[0013] Preferably, cylinders are installed on both sides of the top of the bearing plate, and clamping plates are installed at the opposite ends of the two cylinders. Place the workpiece to be polished on the top of the bearing plate, and the two cylinders push the two clamping plates to clamp and fix the workpiece.

[0014] Preferably, fixing holes are formed in the bottom of the fixing frame in a rectangular array, and the fixing holes penetrate through the bottom of the fixing frame. Through the fixing holes of the fixing frame, tools such as bolts are used to fix the fixing frame on the bearing structure.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, by arranging a grinding machine and a brush plate, the screw sleeve drives the grinding machine to move horizontally to polish the workpiece. The screw sleeve drives the brush plate to move horizontally through two springs. Under the influence of the elastic force of the two springs, the brush plate contacts the surface of the workpiece. During the movement of the brush plate, the debris generated by polishing the surface of the workpiece is swept away, achieving the effect of sweeping away the debris generated by polishing the surface of the workpiece while polishing the workpiece, reducing the cleaning workload of the staff.
