Digital-controlled ball bear inner ring grooved railway multifunctional grinder

Abstract

The invention relates to a digital-controlled ball bear inner ring grooved railway multifunctional grinder, comprising a grinding wheel drive mechanism in transverse movement and a workpiece feeding mechanism in longitudinal movement, wherein, a workpiece box of the workpiece feeding mechanism is assembled with a workpiece planker in an articulated manner through an adjustable rotation shaft, and the rotary angular width of the workpiece is no less than 90 degrees corresponding to the workpiece planker. The digital-controlled ball bear inner ring grooved railway multifunctional grinder in the invention integrates the processing functions of the traditional special grinder, namely, the digital-controlled ball bear inner ring grooved railway grinder in 3M13 category with the digital-controlled thrust ball bearing ring grooved railway grinder in 3M10 category, can process all categories of ball bearing ring grooved railways in the machinable size range, has multiple functions, flexible maneuverability and strong adaptability, and can save production cost and space for enterprises to a greater extent. The invention also has simple structure improvement, convenient operation and higher popularization value and economic benefit.

Description

1. Technical Field: [0001] The invention relates to a processing technology for the inner race of a bearing, in particular to a multifunctional grinding machine for the inner race of a numerically controlled ball bearing. 2. Background technology: [0002] In the prior art, most ball bearing processing still uses traditional special grinders. For example, CNC ball bearing inner ring raceway grinder 3M13 category (such as Figure 10-1 , Figure 10-2 As shown), it is mainly used to grind the outer side groove of the inner ring of the ball bearing. The specific workpieces processed are deep groove ball bearings, angular contact ball bearings (one-time grinding of grooves and slopes), four-point contact ball bearings, etc. The inner ring channel. Such as Figure 10-2 As shown, although the workpiece box of the 3M13 type grinding machine can rotate a small angle α (α is not greater than 30°), this angle is only used to adapt to the grinding of the inner ring of the tapered bearing, an...

Problems solved by technology

For small and medium-sized enterprises with limited capital and scale, purchasing two special grinding machines (3M13 grinding machines and 3M10 grinding machines) at the same time not only needs to take up a lot of money, but also because of the small number of production batches, the special grinding machines are idle for a long time. Not conducive to the intensive economic development requirements currently advocated
