Technical Field

The invention relates to a grinding machine equipment technology, in particular to a grinding machine diamond roller dresser capable of preventing water mist permeation.

Background

The diamond roller is a grinding wheel dressing tool, which rotates at a certain speed (so as to reduce the relative speed of the roller and the grinding wheel), and generates grinding and rolling effects on the surface of the grinding wheel rotating at a high speed, so that the grinding wheel obtains a sharp working surface matched with the profile of the roller, and the linearity of the formed grinding wheel is improved, thereby improving the product quality and the production efficiency.

The existing diamond roller dresser mainly has three structural forms: the diamond roller wheel dresser has the advantages that the diamond roller wheels of the structures are located on a rotating shaft or a specific shaft sleeve, one end of the diamond roller wheel dresser is connected with a driving device, and the other end of the diamond roller wheel dresser is not provided with a fixed point. Secondly, for example, patent publication No. CN202123434U discloses a diamond roller dresser for a grinding machine, which is used for overcoming the instability defect of the first structure, two ends of a main shaft are positioned on a base or a pressure plate, and a diamond roller is installed in the middle of the shaft. However, a large amount of water mist can be generated when the grinding wheel is dressed by the grinding machine, the water mist can not enter the grinding wheel without holes, the two ends of the spindle of the structure are connected by the optical axis, the traditional damp-proof structure is adopted for mounting the diamond roller and the bearing of the sleeve, the water mist can invade the bearing of the diamond roller and the bearing of the sleeve for a long time, the precision is affected, and the service life of the equipment is great. Therefore, the third structure, for example, the patent publication No. CN202955132U, discloses a vertical motor bearing water mist-proof structure, and the patent publication No. CN107932322A discloses a method and a structure for preventing water mist of a large-torque grinding machine spindle, which are based on the common structure of the shaft and bearing assembly mode, and make some improved designs for salted fish pieces such as a bearing lock nut, a bearing outer cover, a bearing seat, a spacer ring or a seal ring, for example, labyrinth seal, serpentine seal, etc., to perform water mist-proof route arrangement. Since the grinding wheel dressing bearings are all high-speed rotating parts, the structures have temporary prevention effect on large water drops, but the protective effect on water mist with fine particles is known, especially after the equipment runs for a period of time.

Disclosure of Invention

The invention aims to solve the problems that in the process of trimming a grinding wheel of a diamond roller, cooling water is quickly gasified due to high temperature generated by a high-speed grinding two wheel to form mist, the mist particles are fine and do not enter pores, powder generated by grinding of the grinding wheel is carried to float, once the cooling water meets the lower temperature part of equipment, the mist particles are condensed into water drops, and because a bearing part is one of the parts with the highest requirement on the precision of a grinding and processing rotating body, the ultrafine mist and dust easily permeate into the bearing part, and the bearing is rusted, abraded and failed for a long time. The grinding machine diamond roller dresser has the advantages of being stable in overall structure, capable of automatically demisting and preventing moisture of a bearing part and the like.

The technical problem of the invention is mainly solved by the following technical scheme: a grinding machine diamond roller dresser capable of preventing water mist permeation comprises a base and a driving motor associated with the base, and is characterized in that an upper supporting plate and a lower supporting plate which are parallel to each other are arranged on the base, the upper supporting plate and the lower supporting plate position a corrector main shaft through a bearing, and a diamond roller is assembled on the corrector main shaft between the upper supporting plate and the lower supporting plate; and the assembling parts of the upper supporting plate, the lower supporting plate and the corrector main shaft bearing are provided with a pneumatic waterproof fog mechanism.
