The numerically controlled inner tooth grinding head consists of cutter shaft, grinding wheel installing angle regulating mechanism, grinding wheel bearing mechanism and driving force transmission mechanism. The grinding wheel installing angle regulating mechanism consists of the lower arced surface of cutter shaft and the upper arced surface of the grinding wheel support; and the driving force transmission mechanism consists of spring soft shaft and bevel gears. The present invention has the advantages of small grinding error, high grinding precision and smooth running.

The invention discloses a flexible grinding and polishing actuator with variable stiffness, which belongs to the technical field of solid wood plate processing. It includes a box body, an active compliance mechanism and a passive compliance mechanism arranged in the box from top to bottom, and a grinding and polishing head mechanism arranged outside the box; an arrangement between the active compliance mechanism and the passive compliance mechanism There is a pressure sensor, and the grinding and polishing head mechanism is connected with the passive compliance mechanism. The invention helps to solve the problems of active and passive separation of common grinding and polishing machines and many disadvantages.

The invention discloses a method for preparing heat-conducting and insulating silicone grease, which comprises a grinding box. Mounting rods are installed between the inner walls of the grinding box through screws. Both ends of the mounting rods are provided with T-shaped grooves. The inside of the swaying groove is slidingly connected with a swaying plate, the outer middle of the rotating shaft is fixedly sleeved with a protruding rod, both ends of the top surface of the filter are welded with protruding blocks, one end of the grinding box is installed with a fan, and one end of the fan is at the bottom of the two bearing plates There are blowing pipes connected to the end positions. Compared with the prior art, the invention makes the ground product move in an inclined arc, so that the product is evenly dispersed, and the purpose of uniform feeding is achieved. The problem of blockage at the bottom of the grinding box occurs, so that The incompletely ground raw material forms an arc-shaped backflow, and through the arc-shaped backflow, it can enter between the two grinding rollers along the tangential direction of the falling raw material, improving the quality and efficiency of grinding, and avoiding the problem of incomplete grinding.

The invention discloses an automatic grinding machine for soles. The machine comprises a control system, a rack and a conveying device, the two ends of the conveying device are the front sole grindingend and the rear sole grinding end, and mechanical arms are distributed at the front sole grinding end and the rear sole grinding end respectively; all the mechanical arms comprise grinding devices installed at the tail ends, a mounting table is placed on the conveying device, and a lifting top support is distributed on the mounting table; a foot die with an upward sole is distributed at the topof the lifting top support, and sole fixing parts are distributed at the front sole grinding end and the rear sole grinding end respectively. According to the automatic grinding machine, the front sole grinding end and the rear sole grinding end are designed, and sole grinding is divided into two grinding working processes in sequence; through cooperation of the designed sole fixing parts and thedesigned lifting top support, the ascending positions of shoes to be processed can be fixed; positioning baffles are designed, and the positions of the shoes to be processed can be precisely limited.Through the design, the grinding errors can be reduced, the grinding quality is improved, and the automatic grinding machine can be widely applied to the technical field of shoe manufacturing.

The invention discloses a method for grinding the spherical surface of a workpiece. According to the method, the workpiece is coaxially and fixedly arranged at the clamping end of a clamping rotating shaft, so that the spherical center of the spherical surface to be machined on the workpiece is coincided with the revolving center of a revolving mechanism; during grinding, the clamping rotating shaft is driven by the revolving mechanism to do centering swing around the revolving center of the revolving mechanism, and the clamping rotating shaft is driven by a rotating shaft driving mechanism to drive the workpiece to rotate around the revolving central axis of the clamping rotating shaft; and a grinding wheel rotates around the revolving central axis of the grinding wheel, and a grinding working surface of the grinding wheel contacts the outer peripheral surface of the spherical surface to be machined on the workpiece to grind the workpiece. By the method, grinding errors are reduced effectively, and grinding accuracy is improved. In addition, the method for grinding the spherical surface is safe, reliable, simple, convenient, high in grinding efficiency and low in machining cost, and has high application value.
