Clamp for difficult-to-machine material turning surface observing and turning experimental method

Abstract

The invention discloses a clamp for difficult-to-machine material turning surface observing. The clamp comprises an installation disc. A boss protruding out of the upper surface of the installation disc and being capable of reserving knife receding space for a turning knife is arranged in the center of the installation disc, a T-shaped groove penetrating through the surface is formed in the upper surface of the installation disc in the radial direction, at least two T-shaped bolts capable of fixing small workpieces to the T-shaped groove are symmetrically arranged in the T-shaped groove along the center of the installation disc, and the center of the installation disc is provided with a center clamping bolt used for fixing a circular plate located on the boss. The boss is symmetrically provided with at least two positioning bolts used for positioning the circular plate along the center clamping bolt. The lower surface of the installation disc is provided with an installation handle matched with a three-jaw chuck of a lathe. The invention further discloses a turning experimental method based on the clamp. The installation disc can effectively clamp the positioning workpieces, and the small workpieces can be clamped at everywhere in the T-shaped groove through a T-shaped bolt clamping mechanism. Turning can be carried out conveniently, and reliability is high.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture and a turning experiment method for observing the turning surface of difficult-to-machine materials. Background technique [0002] In the existing turning process, the bar material is generally selected to use a three-jaw chuck or a similar clamping structure for the turning workpiece. However, when doing the observation of the turning surface, after the turning is completed, a small piece of the surface is removed from the turning surface for surface observation after secondary processing. The cutting heat and cutting force generated by the secondary processing will affect the original The turned surface is affected, resulting in a difference between the observed surface of the sample and the actual turned surface, especially for difficult-to-machine materials. In addition, before the turning test of the sampled bar material, the sampled section material needs to be turned into a cylinder...

However, when doing the observation of the turning surface, after the turning is completed, a small piece of the surface is removed from the turning surface for surface observation after secondary processing. The cutting heat and cutting force generated by the secondary processing will affect the original The turning surface is affected, causing the difference between the observed surface of the sample and the actual turning surface, especially for difficult-to-machine materials.

In addition, before the turning test of the sampled bar, the material of the sampling section needs to be turned into a cylinder before the turning test can be performed again, and the observation sample cannot be reused, which has caused a lot of waste of material
