Problems solved by technology

[0002] A grinder is a commonly used grinding tool in processing and production. Its structure mainly includes a machine base, a grinding wheel, a driving device, and a belt transmission mechanism. The device is connected, and the driven wheel of the belt transmission mechanism is set coaxially with the grinding wheel. During the grinding process, the grinding wheel is in direct contact with the grinding workpiece. Therefore, as the use time of the grinding wheel increases, the diameter of the grinding wheel will gradually decrease. However, due to the transmission mechanism The driving wheel and the driven wheel are driven by a belt without a speed change mechanism, so the linear speed of the grinding wheel will decrease, which will affect the grinding speed and grinding effect. On the other hand, the set grinding wheel cover is fixedly installed on the grinding wheel. Around, when the diameter of the grinding wheel becomes smaller, the radial distance between the outer edge of the grinding wheel and the wheel cover will increase. In this case, the protection of the wheel cover to the operator will be weakened. Among them, when the diameter of the grinding wheel becomes smaller to a certain extent, in order not to affect the grinding efficiency and protect the personal safety of the operator, only the grinding wheel can only be replaced. On the one hand, the service life of the grinding wheel is reduced, causing economic losses to the manufacturer. On the one hand, frequent replacement of grinding wheels directly affects production and processing efficiency

Embodiment 1

[0015] Embodiment 1: as figure 1 A safe high-speed grinding machine shown in the structure includes: a machine base installed on the concrete foundation by means of fixing bolts 15, a grinding wheel, a driving device, and a belt transmission mechanism; The driving wheel of the mechanism is connected to the motor as the driving device, and the driven wheel of the belt transmission mechanism is coaxially arranged with the grinding wheel. The key improvement is that the structure also includes a screw 11 installed on the machine base 1 by means of the bearing seat 5, and the The leading screw nut provided with the leading screw 11 is hinged on the driving wheel 12 and the mounting seat 13 of the motor for installing the belt transmission mechanism, and the driven wheel 7 coaxially arranged with the grinding wheel 6 is a belt-type stepless speed regulating wheel, connected to the grinding wheel 6 and the transmission shaft 17 of the driven wheel 7 are mounted on the top of the mac...

Embodiment 2

[0017] Embodiment 2: as figure 2 , image 3 In the shown high-speed safety grinder, a grinding wheel safety cover 8 is added on the basis of Embodiment 1. The grinding wheel safety cover is hinged at the front end of the grinding wheel cover, and a pull rod 10 slidingly connected to the mounting base is hinged at the bottom end, and the screw 11 is operated. When performing variable speed adjustment, the mounting base 12 rotates around the hinge 14 hinged to the base 1, so the connection point between the pull rod 10 and the mounting base 13 also rotates around the hinge 14 hinged to the base of the mounting base, and a sliding sleeve is arranged between the pull rod 10 and the mounting base. , when the mounting base rotates to achieve speed regulation, the pull rod 10 drives the grinding wheel safety cover 8 hinged at the front end of the grinding wheel cover to rise or fall, keeping the distance between it and the outer edge of the grinding wheel constant, effectively ensur...

Abstract

The invention discloses a safe and high-speed grinding wheel machine, which comprises a base, a grinding wheel, a driving device and a belt transmission mechanism, wherein a driving wheel of the belt transmission mechanism, which is arranged on the base by means of a mounting seat, is connected with the driving device. The driven wheel of the belt transmission mechanism and the grinding wheel arranged at the top of the base by means of a bearing seat are coaxially arranged. The safe and high-speed grinding wheel machine also comprises a screw rod arranged on the base by means of the bearing seat, and a grinding wheel safety cover hinged to the front end of a grinding wheel guard. The bottom of the grinding wheel safety cover is hinged with a pull rod slidably connected with the upper end of a screw rod nut hinged to the mounting seat. The screw rod nut which is arranged in match with the screw rod is hinged onto the mounting seat that is used for mounting the driving wheel of the belt transmission wheel and the driving device. Due to the adoption of the safe and high-speed grinding wheel machine, by regulating the centre distance between the driving wheel and the driven wheel in the driving device, the tension force of a belt is changed and the transmission ratio of the belt transmission mechanism is increased. The linear velocity of the grinding wheel is ensured to be consistent when the diameter of the grinding wheel is reduced, and the utilization ratio of the grinding wheel is improved.
