Grinding machine with coarse-fine grinding structure

Abstract

The invention discloses a grinding machine with a coarse-fine grinding structure. The grinding machine comprises a grinding machine body, a lifting device, a longitudinal bevel gear and a belt pulley;two pressing plates are arranged below the grinding machine body; the pressing plates and first nuts are fixed through a first rotating shaft; a fixing plates is arranged on the first rotating shaft;a threaded sleeve is fixed to the joint of the fixing plate and the first rotating shaft; and sliding blocks are welded to the two ends of the lifting plate, and sliding grooves matched with the sliding blocks are fixed to the positions, on the two sides of the sliding blocks, of the inner wall of a bottom plate. The grinding machine with the coarse-fine grinding structure provided by the invention is provided with the adjustable pressing plates, a worker can adjust the positions of the pressing plates by twisting a threaded rod, a ground object in any shape can be fixed conveniently, meanwhile, the contact area of the pressing plates and the ground object can be maximized through the arrangement positions of the pressing plates, the fixing performance is higher, and the worker can also adjust the ascending and descending of the lifting plate by twisting the threaded rod, and the space position between an object needing to be ground and the grinding machine is better adjusted.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a grinder with a grinding thickness structure. Background technique [0002] With the continuous development of society and the continuous progress of science, grinders are common equipment used to sharpen various knives and tools, which are mainly composed of bases, grinding wheels, motors or other power sources, brackets, protective covers and water Composed of tools, etc., the grinder has brought great convenience to our production and life. [0003] In the prior art, when the traditional grinder grinds objects with different thickness structures, it generally grinds by replacing the grinding head or selecting a grinder of corresponding specifications, which is troublesome and inconvenient, and objects with different thickness structures cannot be processed on the same grinder. Grinding reduces the scope of application of the device, so there is an urgent need for a gr...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of grinder with grinding thickness structure, to solve the traditional grinder proposed in the above-mentioned background technology, when grinding objects with different thickness structures, generally by replacing the grinding head or selecting the grinder of the corresponding specification. Grinding is troublesome and inconvenient. Objects with different thickness and structure cannot be polished on the same grinder, which reduces the scope of application of the device.
