Two-freedom-degree mechanical protection mechanism of cutting-off cutter and use method thereof

Abstract

The invention provides a two-freedom-degree mechanical protection mechanism of a cutting-off cutter and a use method of the two-freedom-degree mechanical protection mechanism. The two-freedom-degree mechanical protection mechanism comprises a cutter, a connecting element, a protection device and a sliding device, wherein the protection device is fixedly connected with one end of the sliding device, the cutter is glidingly connected with the gliding device through the connecting element, and the protection device horizontally slides relative to the cutter through the gliding device. The two-freedom-degree mechanical protection mechanism concretely comprises a first screw nut, a first screw rod, a second screw nut, a second screw rod, a base, a cutter blade, a protecting sleeve, an elastic sheet, a slide block, a third screw nut, a first screw, a fourth screw, a second screw, a second spring, a second position limiting block, a first spring and a first position limiting block. The two-freedom-degree mechanical protection mechanism is provided with the two-freedom-degree cutter, the protection device adopts the one-hundred-percent mechanical structure, and the structure is simple and reliable; the automatic device based on an electronic device is not needed, and the use of electric circuits and motors is avoided; the operation is simple, and the operation action addition is not needed; the normal use of the cutter is not hindered by an automatic protection function of the cutter.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a two-degree-of-freedom mechanical protection mechanism for a cutting tool and a use method thereof. technical background [0002] In terms of industry, the machinery manufacturing industry is the basic industry of the national economy. It affects the development of various sectors of the national economy, and also affects the national economy and people's livelihood and the strengthening of national defense forces. The development of any industry in the national economy must rely on the support and equipment of the machinery manufacturing industry; in the composition of national economic productivity, the role of manufacturing technology accounts for more than 60%. Therefore, all countries put the development of machinery manufacturing industry in the first place. The world's developed countries dominated by the United States believe that the sour...

Problems solved by technology

Although this protection method is very simple in structure, it is inconvenient to use and needs to be removed or put on manually, which affects work efficiency.

Moreover, when using a tool, it is impossible to protect the user from contact with the cutting edge in real time, which is likely to cause labor injury
