Splined hub middle hole boring equipment with size adaption function

Abstract

The invention discloses splined hub middle hole boring equipment with a size adaption function, and relates to the technical field of automobile part production. The equipment specifically comprises abase, a scrap iron collecting mechanism, an adjustable boring mechanism, an inner hole machining pin and a self-centering lever clamp, wherein a control end is arranged on one side of the base, a cutting fluid sprayer is arranged on one side of a shaft sleeve, and a press claw is arranged at the top end of a trapezoidal base. According to the splined hub middle hole boring equipment with the sizeadaption function, through the arrangement of the scrap iron collecting mechanism, and the structure that a flow guide groove is hidden in a groove 20-60 cm away from the top end of the base, the cutting fluid and the scrap iron are prevented from overflowing due to too small height, and the spiral transmission effect is not obvious and the scrap iron is easily accumulated in the middle of the groove to cause blockage due to too large height is avoided; and due to the sawtooth-shaped structural design of a spiral progressive blade, the sawtooth-shaped spiral blade has the advantages of high efficiency of a rectangular spiral blade and high strength of a trapezoidal spiral blade, and can adapt to rapid conveying of the scrap iron and cutting fluid waste.

Description

technical field [0001] The invention relates to the technical field of auto parts production, in particular to a spline hub center hole boring pin device with a size self-adaptive function. Background technique [0002] The automatic transmission is a key part of the car, and the spline hub in the transmission clutch is a key part of the transmission. Generally, the spline hub of the automatic transmission clutch of a car is shaped like a cylinder with a bottom surface, and there are teeth on the cylinder surface. The spline hub is the hub connected by the spline shaft. The spline shaft is a kind of mechanical transmission. It has the same function as the flat key, semi-circular key and oblique key. They all transmit mechanical torque. The rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc. [0003] The existing sp...

Problems solved by technology

[0003] The existing spline hub center hole boring pin equipment has common problems as follows: the spline hub is an important part of the non-constant velocity drive shaft assembly. According to its design requirements, the center hole needs to be bored. The traditional spline hub The method of hub boring and center hole is to position and clamp the splined hub on the three-jaw chuck on the fixed workbench for processing. When clamping the workpiece, it needs to manually tighten and loosen the screw many times, which is labor-intensive and low in production efficiency. The bottleneck process that restricts production capacity, and the existing boring pin equipment cannot quickly adapt to the internal aperture processing of different sizes and specifications of the materials to be processed, and it takes a lot of energy to manually replace the boring tool corresponding to the shape to be processed, which is inefficient
