Embodiment Construction

[0039] Processing technology for producing high-precision bearing adapter sleeves:

[0040] The general process method of the present invention adopts the one-time clamping molding process of the numerical control machine tool. Take the processing of H318 as an example, such as figure 2 The tube blank is selected as shown, the outer diameter of the tube is φ95, the inner diameter is φ76, and the width B1=68

[0041] Processing method of the present invention is as follows:

[0042] 1. Internal stress relief annealing:

[0043] 30KW well-type resistance furnace, heating up to 730°C, holding for 1.5 hours, then cooling down to below 200°C with the furnace.

[0044] 2. Machining datum surface: such as figure 2 shown

[0045] φ93 +0.1 Datum surface out of roundness ≤0.03

[0046] 3. Car hydraulic automatic chuck jaws: the turning diameter of the three jaws is φ92-0.1, and soft jaws are used. The arc length of the three soft jaws is not less than 1 / 3 of the circumference o...

Abstract

The invention discloses a method for machining a high-precision bearing adapter sleeve. The method comprises the following steps: (1) removing inner stress of a workpiece; and annealing the workpiece; (2) processing the benchmark surface (3) using a lathe to cut a clamping claw of a hydraulic automatic chuck; (4) adjusting a clamping force of a hydraulic oil cylinder; removing the windage of a mainshaft to ensure cutting; adjusting the clamping force of the oil cylinder through an overflow valve and a hydraulic valve of the hydraulic oil cylinder; and oil pressure is within the range between 1 and 4 Pa; (5) adopting a machine clamp to rotate the position of a cutter; adopting a blade material of 1 / T15, wherein in a titanium carbide coating layer, a positive rake angle r is between 10 and 15 degrees; a rear angle alpha is between 5 and 8 degrees; an end cutting edge angle phi is 15 degrees; and (6) processing the workpiece by the mounting of four working positions. With the matching with the high-precision bearing adapter sleeve, a bearing has smooth operation, no vibration and no noise and can improve service life by 30 to 100 percent averagely.

Description

Technical field: [0001] The invention belongs to the technical field of metal cutting processing of mechanical basic components, and in particular relates to a processing method for a high-precision bearing adapter sleeve. Background technique [0002] The adapter sleeve product is an accessory of rolling bearings. It is used in conjunction with bearings with inner tapered holes. It is mainly used on multi-fulcrum optical shafts that do not bear large axial forces and do not have shaft shoulders. Its structural advantages: the disassembly and assembly of the bearing after wear is very convenient, and will not cause damage to the assembly shaft shoulder, which greatly reduces the accuracy requirements for the shaft shoulder processing. [0003] Rolling bearings are interchangeable mechanical basic parts, and their inner diameter, outer diameter, and clearance precision requirements are very high, so the precision of the adapter sleeve used in conjunction with it must also be ...
