Grinding and polishing machine applicable to deep-well oil-production drilling bit

Abstract

The invention discloses a grinding and polishing machine applicable to a deep-well oil-production drilling bit. The grinding and polishing machine comprises a transmission chamber, arm beams and a water pump. The grinding and polishing machine is characterized in that the transmission chamber is internally provided with a motor I, a cooling-liquid pool and an infrared-ray detector, and the outer wall of the transmission chamber is provided with lifting lugs and a controller; the arm beams are fixedly arranged on the transmission chamber by installing bolts, and are provided with fixed blocks and rotary shafts; the fixed blocks are provided with motors II which are provided with driving wheels; the rotary shafts are provided with driven wheels, and the two ends of the rotary shafts are respectively provided with balancing blocks and installing blocks; the driven wheels are connected with the driving wheels; and the water pump is arranged on the transmission chamber, and is provided with a liquid discharging pipe and a liquid pumping pipe. The grinding and polishing machine disclosed by the invention has the advantages that a workpiece on the installing blocks and a grinding disc rotate at high speed, air between the workpiece and the grinding disc form a vortex and the grinding and polishing operation is carried out on the workpiece by the vortex, so that the grinding accuracy for the workpiece is improved and the service life of the grinding disc is prolonged.

Description

technical field [0001] The invention relates to a grinding and polishing machine, in particular to a grinding and polishing machine suitable for deep well oil production drill bits. Background technique [0002] With the development of society and the increase in the use of petroleum resources, petroleum exploration has also shifted from shallow mining to deep well mining, and the geographical conditions of deep wells lead to higher precision of deep well oil production bricks. Existing deep well oil production drill bits mostly use polishing and grinding machines to polish and grind the drill bit. During the polishing and grinding process of the drill bit, the contact grinding between the drill bit and the grinding disc will cause damage to the grinding disc, shorten the service life of the grinding disc, and reduce the life of the drill bit. Grinding accuracy, the heat generated by grinding and polishing will increase the temperature of the drill bit, and high temperature...

Problems solved by technology

[0003] The purpose of the present invention is to provide a drill bit and a grinding disc to solve the problems that the grinding disc is damaged during the grinding and polishing process of the existing oil extraction drill bit, which reduces the grinding accuracy of the drill bit, shortens the service life of the grinding disc, and reduces the quality and performance of the drill bit. Non-contact grinding, prolonging the service life of the grinding disc, and automatically detecting the flatness and smoothness of the workpiece are suitable for deep well oil production drill bit grinding and polishing machines, improving the grinding accuracy and quality performance of the drill bit
