A Javelin Grinding Machine Tool

Abstract

The invention belongs to a javelin grinding machine tool which comprises a tool body, a rotating shaft, an abutting mechanism and a grinding mechanism. The rotating shaft is arranged at one end of the tool body, the abutting mechanism is arranged at one end of the tool body and corresponds to the rotating shaft, the grinding mechanism is arranged on the tool body through a sliding rail and positioned between the rotating shaft and the abutting mechanism, a locking mechanism is arranged between the abutting mechanism and the tool body, and an adjusting screw pushing the grinding mechanism to be in reciprocating motion is arranged between the grinding mechanism and the tool body. Two ends of a javelin blank are supported, the javelin blank is rotated by the rotating shaft, and at the same time, an abrasive belt machine matched with an abutting wheel grinds a javelin; radian of the surface which is ground is controlled jointly by an auxiliary adjusting screw and the adjusting screw, so that grinding of the surface of the javelin blank can be completed accurately, quickly and efficiently to meet standards, mechanization level is high, and the grinding process of the javelin blank can be completed quickly, efficiently and accurately; the whole javelin grinding machine tool automatically controls a running track of the abrasive belt machine in the whole process through a control system, and strict standardization can be realized.

Description

technical field [0001] The invention belongs to the field of javelin production equipment, and in particular relates to a javelin grinding machine tool. Background technique [0002] In the ancient Greek era, in the ancient Olympic Games, people have already started to use the javelin run-up throw and spot throw as competitive events. After withdrawing from the military arena entirely, the javelin became a purely athletic event. In 1792, Sweden held the world's first modern javelin throw competition. The men's and women's javelin throws were included in the modern Olympic Games in 1908 and 1932, respectively. Therefore, the IAAF has strict regulations on the shape, size, material and structure of the javelin, and the production of the javelin must meet the requirements. [0003] It is necessary to determine the center of gravity, weight and shape after the production of the javelin and the subsequent shaping process. These three tasks are all polished through the work exp...

Problems solved by technology

[0003] It is necessary to determine the center of gravity, weight and shape after the production of the javelin and the subsequent shaping process. These three tasks are all polished through the work experience of the staff. The production efficiency is low, the yield is low, the processing speed is slow, and the labor cost is high. poor standardization
