Grinding, as a key process in mechanical parts processing, undertakes important tasks such as deburring, dimensional correction, and improving surface finish. The performance of grinding equipment not only affects processing efficiency but also the final quality of the product. From precision grinding of engine blocks in automobile manufacturing to surface treatment of titanium alloy components in the aerospace field; from polishing of precision components in 3C electronics to grinding of complex curved surfaces in mold manufacturing, different application fields have placed diverse demands on the precision, efficiency, and adaptability of grinding equipment. Therefore, developing high-performance, intelligent grinding equipment for mechanical parts processing has become a core driving force for promoting high-quality development of the manufacturing industry and meeting the requirements of refined industrial production.

This operation is prone to tilting or shifting of the grinding head, resulting in one-sided wear of the grinding head, which in turn leads to excessive wear in certain areas. Furthermore, it causes inconsistent grinding amounts on the surface of the parts, resulting in flatness errors and affecting the quality of the finished product. Utility Model Content

[0020] 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.

[0021] Please see Figures 1-4 The present invention provides the following technical solution: a grinding device for machining mechanical parts, comprising a grinding frame 1, a motor 2 mounted on the longitudinal end surface of the grinding frame 1, a ball screw 3 connected to the output end surface of the motor 2, a movable frame 4 threadedly connected to the surface of the ball screw 3, the movable frame 4 slidably connected to the top transverse end surface of the grinding frame 1, a servo motor 5 mounted on the bottom surface of the movable frame 4, a grinding disc 6 connected to the output end surface of the servo motor 5, a crossbar on the other side of the grinding disc 6 sleeved in a bearing on one side of a bearing frame 7, the top surface of the bearing frame 7 connected to the bottom of the movable frame 4, a fixed frame 8 connected to the inner wall surface of the longitudinal end of the grinding frame 1, a rotating frame 10 threadedly connected to one side of the fixed frame 8 by bolts 9, a clamping rod 11 threadedly connected to one side of the rotating frame 10, and rotating rods 12 connected to both sides of the rotating frame 10, the rotating rods 12 being rotatably sleeved in through slots opened on both sides of the fixed frame 8.

[0022] Preferably, the top of the grinding frame 1 has a rectangular groove, and the shape and size of the groove are adapted to the protrusions on the inner wall of the movable frame 4.

[0023] In practical use, the groove on the top of the grinding frame 1 is used to facilitate the parallel movement of the moving frame 4 on the top of the grinding frame 1 with the cooperation of the motor 2 and the ball screw 3. The moving frame 4 is sleeved on the top of the grinding frame 1 and moves parallel to each other, so that the moving frame 4 can be stably adjusted in position.

[0024] Preferably, the grinding frame 1, the ball screw 3, and the moving frame 4 form a threaded connection structure.

[0025] In practical use, the rotation of the ball screw 3 on the top of the grinding frame 1 drives the threaded movable frame 4 to move parallel to the top of the grinding frame 1.

[0026] Preferably, the fixing frame 8, bolt 9 and flipping frame 10 form a threaded connection structure.

[0027] In practical use, the bolts 9 threaded between the fixed frame 8 and the flipping frame 10 are unscrewed, thereby driving the flipping frame 10 to rotate and flip within the circular grooves on both sides of the fixed frame 8.

[0028] Preferably, circular through slots are opened laterally on the longitudinal end surfaces of both sides of the fixing frame 8, and the shape and size of the through slots are adapted to the rotating rod 12.

[0029] In practical use, the rotating rods 12 connected to both sides of the flipping frame 10 rotate within the circular through slots on both sides of the fixed frame 8, thereby flipping and adjusting the position of the flipping frame 10 on the surface of the fixed frame 8.

[0030] Preferably, two sets of through slots are symmetrically opened on both sides of the longitudinal end of the grinding frame 1, and the shape and size of the through slots are adapted to the rotating rod 12.

[0031] In actual use, when the flipping frame 10 rotates inside the fixed frame 8, the clamping rod 11 with its surface threaded connection rotates in the through slots opened on both sides of the grinding frame 1 to avoid being blocked during rotation.

[0032] Working principle: When machining and grinding rectangular parts, the parts to be ground are placed on the inner wall of the tilting frame 10. Then, the clamping rods 11 threadedly connected to both sides of the tilting frame 10 are rotated sequentially in the direction of the parts. This causes the two sets of clamping rods 11 to abut against the surface of the parts. The surface of the clamping rods 11 is equipped with anti-slip rubber pads, and the rod body adopts an adjustable structure of screw and nut. Rotating the clamping rods 11 can simultaneously tighten or loosen the clamps on both sides, realizing the rapid clamping of parts of different sizes, thereby fixing the position of the parts within the tilting frame 10. Then, the external power supply connected to the motor 2 and servo motor 5 is started simultaneously. The servo motor 5 drives the connected grinding disc 6 to rotate within the bearing frame 7. The bearing frame 7 uses deep groove ball bearings or angular contact bearings, which can withstand the radial load and part of the axial load when the grinding disc 6 rotates, ensuring the stability of the grinding disc 6 during the grinding process and reducing the impact of vibration on the machining accuracy, thereby making the grinding disc... 6. The burrs on the surface of the bottom-contacting parts are polished. While the polishing disc 6 polishes the burrs on the surface of the parts, the moving frame 4 is driven by the ball screw 3 to move parallel to the top of the polishing frame 1, so as to uniformly polish the surface of the parts clamped and fixed on the flipping frame 10. After one polishing process is completed, the motor 2 and the servo motor 5 are turned off, and the bolt 9 threaded between the fixed frame 8 and the flipping frame 10 is unscrewed, so as to drive the flipping frame 10 to rotate and flip in the circular grooves on both sides of the fixed frame 8. When the flipping frame 10 rotates in the fixed frame 8, the clamping rod 11 threaded on its surface rotates in the through grooves opened on both sides of the polishing frame 1 to avoid being blocked during rotation. After flipping, the above operation is repeated, and the two bolts 9 are threaded between the fixed frame 8 and the flipping frame 10 respectively to fix the position of the flipping frame 10 after the flipping angle. Then the motor 2 and the servo motor 5 are started again to polish the other side of the parts.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
