Grinding machine convenient to use

Abstract

The invention discloses a grinding machine convenient to use. The grinding machine comprises a grinding machine body; grinding wheels are mounted at the two ends of the grinding machine body; a protection cover fixed to the grinding machine body is arranged outside the grinding wheels; first sleeves are fixed to the two sides of the lower end of the grinding machine body; vertical rods are inserted into the lower ends of the first sleeves; a cabinet body is fixed to the lower end of each vertical rod; cushioning springs arranged on the vertical rods in a sleeving mode are arranged between thefirst sleeves and the cabinet bodies; a vertical plate fixed to the cabinet bodies is arranged between the two vertical rods; a first gear is rotationally connected to the front surface of the vertical plate; a hand wheel is fixed to the front surface of the first gear; a connecting plate fixed to the vertical plate is arranged on one side of the first gear; a bolt penetrates through the connecting plate and is in threaded connection with the connecting plate; a rack is fixed to the side end of one of the first sleeves; the first gear meshes with the rack; the end, opposite to the first gear,of the bolt is in a conical shape, and the diameter of the end is smaller than the tooth pitch of the first gear; a transverse shaft is fixed to the side end of the protection cover; and the transverse shaft is sleeved with a second sleeve. The grinding machine is safe, labor-saving and convenient to use.

Description

technical field [0001] The invention relates to the field of grinder equipment, in particular to an easy-to-use grinder. Background technique [0002] Grinding machines are widely used in the field of metal cutting and grinding, especially in the cutting work of knives, and grinding machines are particularly important. However, the grinder is a high-speed rotating mechanical device. During the process of sharpening the tool, the grinding wheel of the grinder is exposed. In this way, if the grinding wheel has cracks or sparks are likely to be generated during tool processing, personal accidents will occur, especially for workers. Holding the knife to sharpen it is prone to unsafe accidents where the knife is not held tightly and flies out, causing personal injury. When grinding, there is a lack of stable fixtures, the accuracy is reduced, and it is time-consuming and labor-intensive. Based on the deficiencies in the prior art, it is urgent to design a grinder that is easy to...

However, the grinder is a high-speed rotating mechanical device. During the process of sharpening the tool, the grinding wheel of the grinder is exposed. In this way, if the grinding wheel has cracks or sparks are likely to be generated during tool processing, personal accidents will occur, especially for workers. Holding the knife to sharpen the blade is prone to unsafe accidents where the knife is not held tightly and flies out, causing personal injury. When grinding, there is a lack of stable fixtures, the accuracy is reduced, and it is time-consuming and laborious.
