Abstract
The invention discloses a high sealing performance device for mining drill bit polishing. The high sealing performance device comprises a sealing gasket, tool chucks, a driving mechanism, a cover, fixing sleeves, brush bristle, a polishing shell, tools, a fixing shaft, sealing rings, a cleaning ring, a movable plate, a nut seat, a first gear, a second gear, a connection shaft, a rotary head, a screw, a movable sleeve, a viewport, first lock screws and second lock screws. The high sealing performance device has the advantages of being reasonable and simple in structure and low in production cost, the tools are installed on the tool chucks in a clamped mode at first, then, the tools are inserted into an abrasive in the polishing shell, the arranged movable plate can be adjusted up and down as required, accordingly, the abrasive can make contact with the cutting edges on the lower sides of the tools better, the polishing use requirements of tools different in length are met, and the polishing quality and efficiency of the tools are improved; then, the driving mechanism is started to drive the tools to rotate to be subjected to polishing operation; and through the sealing gasket, leakage of the abrasive during polishing can be effectively avoided, and accordingly, the working environment quality is improved.
Description
[0001] This application is a divisional application, the filing date of the parent case is: September 21, 2017, the application number is: 201710860084.X, and the patent name is: a high sealing performance device for mining drill bit polishing. Technical field: [0002] The invention relates to the technical field of polishing equipment, in particular to a device with high sealing performance for mining drill bit polishing. Background technique: [0003] The edge polishing and passivation technology of cutting tools is a very important issue that has not been paid attention to by people generally. The cutting edge of the cutting tool has microscopic notches (that is, micro chipping and kerf) of different degrees. As people have higher and higher requirements for the surface quality of cutting products, the performance and stability of cutting tools have put forward higher requirements. For the currently popular diamond-coated cutting tools, the passivation treatment of the ...
