A fixed tool for processing the ear hole of the transmission shaft

Abstract

The invention relates to a fixing tool for processing a transmission shaft earhole. The fixing tool comprises a base, two fixing devices and a spline shaft, wherein a limiting screw hole is formed inthe upper surface of the base; a sliding chute is formed in the two sides of the limiting screw hole; a limiting screw rod matched with the limiting screw hole in structure is fixedly arranged at thelower end of the spindle shaft; the two fixing devices are symmetrically arranged at the two ends of the base; each of the fixing devices comprises a fixing plate, a limiting block and a connecting screw rod; the fixing plate is perpendicularly and fixedly connected with the upper surface of the base; a connecting screw hole matched with the connecting screw rod in structure is formed in the center of the fixing plate; a rotating block is fixedly arranged at one end of the connecting screw rod; the other end of the connecting screw rod penetrates through the connecting screw hole and is perpendicularly and fixedly connected with a rotating rod; one end of the rotating block is fixedly connected with the connecting screw rod; the other end of the rotating block is rotatably connected with the outer surface the limiting block; the internal surface of the limiting block is arc-shaped; and a sliding block matched with the sliding chute in structure is fixedly arranged at the lower end of the limiting block. The fixing tool has the advantages of being convenient to use, wide in applicability and steady and firm in connection.

Description

technical field [0001] The invention belongs to the technical field of transmission shaft processing, and in particular relates to a fixed tool for processing transmission shaft ear holes. Background technique [0002] The transmission shaft is a rotating body with high speed and few supports. The transmission shaft is divided into many sections, and the joints are connected by universal joints. During the process, the size needs to be strictly controlled; however, when the existing drilling machine drills the ear holes of the transmission shaft parts, the connection between the fixing device and the transmission shaft parts is not stable, and it is easy to be damaged due to The connection is not stable and the transmission shaft shakes, resulting in the problem of inaccurate processing; therefore, in order to solve the above problems, it is necessary to develop a fixed tool for processing the ear hole of the transmission shaft that is easy to use, wide in applicability and ...
