Problems solved by technology

[0004] The purpose of the present invention is to provide a centerless grinding process for rods and its special purpose for the disadvantage that the outer circular surface cannot guarantee the coaxiality due to the vibration of the outer circular surface with the abrasive tool in the existing centerless grinding process of the bar. The knife plate adjustment device can adjust various parameters of the delivered abrasive tool according to various types of bars, so that the outer circular surface of the bar to be delivered can achieve the best processing accuracy

Embodiment Construction

[0031] The present invention will be further explained below in conjunction with the drawings and embodiments.

[0032] As attached image 3 As shown, a centerless grinding process for bar materials includes the following steps: first, rough machining the bar materials so that the workpiece allowance is between 0.3 and 0.5 mm, the roundness error is below 0.10 mm, and the straightness is within Within 1mm / m.

[0033] Then train the guide wheel, adjust the speed of the guide wheel to the fastest, turn on the hydraulic system and the guide wheel; trim the guide wheel before processing, adjust the speed of the guide wheel to the fastest, turn on the hydraulic system and the guide wheel. When correcting the guide wheel, adjust the diamond drill down little by little until it just touches the guide wheel. Then correct the guide wheel according to the scale on the corrector, and adjust 5 small divisions down at a time. The correction speed can be faster at the beginning and slower in t...

Abstract

The invention relates to a bar centerless grinding technology and a special knife board adjusting device thereof; the bar centerless grinding technology comprises the following steps of: firstly carrying out rough machining on a bar so as to enable the workpiece allowance to be between 0.3mm and 0.5mm, the roundness error is below 0.10mm and the straightness accuracy is within 1mm / m; the bar centerless grinding technology and the special knife board adjusting device thereof disclosed by the invention can efficiently eliminate or reduce the original roundness error of a bar blank, thereby controlling the roundness error of a workpiece finished product, improving the product percent of pass and saving the production cost; the whole process flow is simple in process and easy to operate; and the special knife board adjusting device is simple in structure, and convenient to debug and maintain.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and specifically relates to a grinding process capable of greatly improving the concentricity during centerless grinding of bars and a special blade adjusting device thereof. Background technique [0002] Grinding uses high-speed rotation Grinding wheel Wait Abrasive Machining the surface of the workpiece Cutting Craft. Grinding is used to process various Artifact The inner and outer cylindrical, conical and flat surfaces, and Thread , gear And splines and other special and complex forming surfaces. Centerless grinding means that when grinding, the workpiece does not need to be centered and supported by the top, but is placed between the grinding wheel and the guide wheel, supported by the pallet below it, and driven by the guide wheel to rotate. As a high-productivity precision machining method, centerless grinding is used as far as possible for parts in the bearing, automobile, a...
