Clamping mechanism of camshaft grinding machine

Abstract

The invention relates to the technical field of camshaft machining equipment, and discloses a clamping mechanism of a camshaft grinding machine. The clamping mechanism comprises a headstock and a tailstock, wherein a transverse headstock hole is formed in a headstock seat, a headstock main shaft is connected to the interior of the headstock hole, one end of the headstock main shaft is connected with a first servo, the headstock main shaft is connected with a headstock flange plate, a fixing ring is arranged on the headstock flange plate in a sleeving mode, and the fixing ring is connected to the headstock seat; the headstock flange plate is fixedly connected with a clamp; and the tailstock comprises a tailstock seat, a vertical plate and a tailstock sleeve are fixedly connected to the tailstock seat, a first through hole is formed in the vertical plate, a second through hole is formed in the tailstock sleeve, a second servo motor is connected to the first through hole of the vertical plate, an output shaft of the second servo motor penetrates through the first through hole to be fixedly connected with a lead screw, and the lead screw is in threaded connection with a connecting plate. According to the clamping mechanism, a camshaft can be stably clamped, so that movement is avoided; and the tailstock can also sense the magnitude of the clamping force and whether a workpiece is accurately in place or not, and the clamping force is automatically adjusted in the grinding process, so that the machining safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of camshaft processing equipment, in particular to a clamping mechanism of a camshaft grinder. Background technique [0002] Camshafts are widely used in gasoline engines or diesel engines to control the opening and closing of cylinder intake and exhaust valves. The quality of its processing directly determines the performance of the engine. [0003] Camshafts are generally made by mold casting, and the surface of cast camshafts is generally rough, but the camshaft runs at high speed in the engine, so the roughness requirements are very high. At present, the grinding and finishing of camshafts are usually done by CNC camshaft grinder Grinding. During grinding, the camshaft is placed in the clamping mechanism of the grinding machine, and the clamping mechanism drives the workpiece to rotate. Through the linkage between the feed movement of the grinding mechanism and the rotational movement of the workpiece, t...

AI Technical Summary

Problems solved by technology

[0004] The clamping mechanism of a camshaft grinder generally includes a headstock and a tailstock, which clamp the camshaft in the middle. The headstock generally needs to drive the camshaft to rotate, and the tailstock can adjust the clamping force on the camshaft. The stability of the clamping of the camshaft by the headstock of the camshaft grinding machine is not good, and the camshaft is easy to move in series during grinding, which affects the machining accuracy of the camshaft; and the current tailstock of the grinding machine cannot self-perceive the clamping of the camshaft. The holding force and the accurate clamping position of the camshaft cannot be stably adjusted and safely protected during the grinding process of the camshaft, so that the flexible processing of the camshaft cannot be achieved
