Abstract
The utility model discloses a novel internal grinding device, which comprises an oil motor (1), an extension rod (2), a short spindle (3), a thrust self-aligning roller bearing (4), a bearing block (5), a grinding wheel guide (6) and a grinding wheel (7). The oil motor (1) is arranged inside the extension rod (2) and connected with the short spindle (3), the thrust self-aligning roller bearing (4) is arranged inside the bearing block (5) and connected with the short spindle (3), the grinding wheel guide (6) is mounted at the front end of the short spindle (3), the grinding wheel (7) is mounted on the grinding wheel guide (6), and the extension rod (2) is connected with the bearing block (5). By altering a motor transmission grinding wheel with a long spindle into an oil motor transmission grinding wheel with the short spindle, the novel internal grinding device increases pushing force of the grinding wheel and improves grinding production efficiency. Additionally, a spindle cooling device (8) is mounted on the outer portion of a drum body of the bearing block (5), thereby reducing heating of the spindle, prolonging service life of equipment and guaranteeing stable running of the internal grinding device.
Description
Technical field
The utility model relates to a kind of novel inner circle grinding device.
Background technology
Traditional internal grinding attachment adopts motor or electric main shaft to drive emery wheel.Because circle is less in the seamless alloy pipe, and motor appearance and size is too big, motor can't be installed to steel duct, can only connect emery wheel and motor by extension bar, for processing seamless alloy pipe bosom, the length that usually makes extension bar and main shaft is above six meters, again because when carrying out above-mentioned internal grinding, the emery wheel vibrations are big, pass to emery wheel after the axle head heating, cause emery wheel place bearing very easily to damage, can't satisfy steady in a long-term production; The operating efficiency of internal grinding is relevant with the downforce that emery wheel is subjected to, and motor-driven internal grinding head is owing to main shaft overlength, rigidity extreme difference, increase downforce that can not be too much.Stall if take place in emery wheel, and motor very easily damages.
The utility model content
The purpose of this utility model is, a kind of novel inner circle grinding device is provided.It will long main shaft motor transmission emery wheel change the oil motor transmission emery wheel of short main shaft into, increased the emery wheel downforce, improved the efficient that grinding is produced; Reduce spindle heat generation, guaranteed the stable operation of internal grinding attachment.
The technical solution of the utility model: novel inner circle grinding device comprises oil motor, extension bar, short main shaft, self-aligning thrust roller bearing, bearing block, emery wheel guide bracket and emery wheel; Oil motor places extension bar inside, and oil motor is connected with short main shaft; Self-aligning thrust roller bearing places in the bearing block, and is connected with short main shaft; Short front-end of spindle is equipped with the emery wheel guide bracket, on the emery wheel guide bracket emery wheel is installed; Extension bar is connected with bearing block.Change original long main shaft into short main shaft, increased the rigidity of main shaft; And make it to connect with self-aligning thrust roller bearing with bearing block, can increase the downforce of emery wheel greatly, improve grinding production efficiency.
In the aforesaid novel inner circle grinding device, described bearing seat cylinder body outside is equipped with main shaft cooling device.By short main shaft of recirculated water cooling and self-aligning thrust roller bearing, the life-span of having improved equipment.
In the aforesaid novel inner circle grinding device, adopt shaft coupling to be connected between described oil motor and the short main shaft.Because vibrations greatly by shaft coupling, can reduce the circular runout of oil motor during grinding attachment work, prevent the oil motor leakage of oil.
In the aforesaid novel inner circle grinding device, oil motor appearance and size is less than processed pipe diameter.Because oil motor appearance and size is less, can enter steel duct.
Compared with prior art, the utility model changes the oil motor transmission emery wheel of short main shaft into by motor transmission emery wheel that will long main shaft, has increased the rigidity of main shaft, has increased the emery wheel downforce, has improved the efficient that grinding is produced; The bearing seat cylinder body main shaft cooling device installed outside has reduced spindle heat generation, has improved the life-span of equipment, guarantees the stable operation of internal grinding attachment.
