Description
Technical Field
The utility model belongs to a processing tool, and particularly relates to a tool for processing an automobile supercharged engine shaft by a spindle on the back of a center-walking type numerical control lathe.
Background
A taper hole is machined at the top end of a slender shaft in the product design of a shaft for an automobile supercharged engine, and the taper hole is used for matching and positioning. The machining sequence is that the size of one side of a product is machined on the side of the main shaft, then the product is automatically clamped on the back main shaft, and a drill bit is used for machining the end face taper hole on the back main shaft. At the moment, the center of the drill bit is not coincident with the center of the product due to the combined action of various factors such as the fact that the machining surface is far away from the clamping surface, the clamp cannot be completely coincident with the back main shaft, the center of the cutter cannot be completely coincident with the center of the product, and the cut product slightly deforms due to material stress. Because the product is rotated during processing, when the center of the product is not coincident with the rotation center (the center of the main shaft), the center of the front end of the product winds the rotation center to form a circular track, and therefore, the phenomenon of core deviation occurs during processing. In severe cases, the conical surface may deviate from the machined surface; the slightly core-shifting is difficult to visually check, and the selection needs to be carried out by methods such as industrial display, image measurement and the like, so that great personnel waste and product scrapping loss are caused. If the device flows out to a client, the device can not be matched and positioned when in use, and the serious result of the failure of the device can be caused.
Disclosure of Invention
The utility model aims to overcome the technical defects and provides a manufacturing tool for processing an automobile supercharged engine shaft by a back main shaft of a walking type numerical control lathe, wherein a bearing is arranged at the left end of the center of a cylindrical main body, a drill bit through hole is arranged at the right center, adjusting locking screws are arranged at the upper side and the lower side of the through hole, and a chip removal groove is formed in the middle.
The technical problem to be solved by the utility model is that: the tool for machining the shaft of the automobile supercharged engine by the aid of the spindle of the walking numerical control lathe comprises a lathe workbench and is characterized in that a drill bit clamp is fixed in the middle of the left surface of the lathe workbench, a drill bit is fixed in the middle of the left side of the drill bit clamp and arranged in a circular main body, a bearing is arranged in the middle of the left end of the main body, the bearing is provided with a workpiece mounting hole which is the same as the inner hole diameter of a coaxial bearing, a drill bit guide through hole is formed in the middle of the right side of the main body, a locking screw for adjustment is in threaded connection with a threaded hole formed in the upper side and the lower side of the drill bit guide through hole, and an oval chip groove is formed in the middle of the threaded hole.
The inlet of the bearing arranged at the left end of the main body is provided with a bearing inlet guide angle, the angle of the guide angle is alpha, and the alpha is 40-50 degrees.
The utility model has the advantages that the bearing center hole and the drill bit guide through hole are on the same central line and can be adjusted by the locking screw, so that the bad core deviation of the taper hole is not generated during the processing of the workpiece, the product quality is high, and the processing efficiency is high.
