Lathe tool damping device

Abstract

The invention discloses a lathe tool damping device, and belongs to the technical field of mechanical equipment. The lathe tool damping device comprises a tool bar and a tool bar mounting seat; one end of the tool bar mounting seat is provided with a mounting groove for mounting the tool bar, and an opening of the mounting groove is provided with a fixing part for fixing the tool bar; the tail part of the tool bar is fixed in the mounting groove, a tool bar extension section is fixedly arranged at the rear end of the tool bar, a movable gap is formed between the tool bar extension section and the inner wall of the mounting groove, and the tool bar extension section is connected with a swing damping device; and the swing damping device comprises a swing rod, a connecting rod, an n-shaped supporting frame, a friction roller and an arc-shaped damping face. According to the device, the influence of vibration of a lathe on the tool bar can be reduced, vibration of the tool bar can be damped at the same time, the damping effect is better, and thus the influence of vibration on processing of the tool bar is reduced, and the processing precision can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a shock absorbing device for a turning tool of a lathe. Background technique [0002] A turning tool is a tool with one cutting part for turning, and is one of the most widely used tools in cutting. When machining deep holes on a machine tool, generally the blade is installed on the cutter head of the tool holder. When processing deep holes, due to the long cutter holder and the heavy weight of the cutter head, chattering is very easy to occur during processing. It not only affects the machining accuracy of the workpiece, but also aggravates the wear of the tool and greatly reduces the service life of the tool. The Chinese invention application with the notification number CN110142424A discloses a turning tool shock absorber for a numerically controlled lathe, specifically disclosing that a tool bar mounting seat is provided at the right end of the secon...

The Chinese invention application with the notification number CN110142424A discloses a turning tool shock absorber for a numerically controlled lathe, specifically disclosing that a tool bar mounting seat is provided at the right end of the second tool bar, and mounting grooves are provided on the upper and lower sides of the tool bar mounting seat , fix the second knife rod in the installation groove, and then install a shock absorbing device between the installation groove and the knife rod. Large, the vibration of the lathe itself is easily transmitted to the tool bar. Furthermore, the shock absorbing device in this technical solution uses a spring. Since the spring needs to be displaced relative to the shock absorbing effect, it cannot achieve a good shock absorbing effect. , leading to poor shock absorption
