Description
Technical field
The utility model relates to lathe and uses chuck, particularly relates to the hydraulic floating chuck that is used for oil pipe and gas thread processing usefulness.
Background technology
In the past, the machined steel gas thread was with the common chuck on the lathe; Need the whole steel pipe center of personnel selection wage adjustment, not high but also time-consuming, the effort of centering precision not only, and the screw thread that processes exists error big; Of poor quality, can only be used for low precision processing, particularly process oil pipe and gas thread; Not only double thread quality, required precision are strict, and surface smoothness is also had strict standard.Therefore, traditional universal chuck makes the gas thread of processing can not satisfy customer requirements far away.
The utility model content
The technical problem that the utility model will solve; Provide a kind of be used for oil pipe and gas thread processing, centering precision is high, chucking is reliable, effectively guarantees the crudy and the precision of gas thread; Saving of work and time, the hydraulic floating chuck of raising product surface fineness and production efficiency.
The technical scheme that adopts is:
The hydraulic floating chuck comprises chuck seat, chuck body, claw, synchronous ring, anti-main cover, gland, fairlead, slide block, chucking oil cylinder, hydraulic control unit and pressurizer.Described chuck body is fixedly connected with chuck seat through screw; Hydraulic control unit is installed in the inside link position of chuck seat and chuck body; Pressurizer is installed in the chuck body with the chucking oil cylinder; The chucking oil cylinder connects pressurizer through fluid pressure line, and pressurizer connects hydraulic control unit through fluid pressure line.Said dust cover is fixed on the chuck body, and gland is fixed on the dust cover, between gland and the chuck body claw is housed, and the gland and the chuck body of claw and both sides are slidingly connected.The piston rod of said chucking oil cylinder connects slide block through screw, and slide block one side is provided with the slide block inclined-plane, and said claw is provided with the claw inclined-plane that is complementary with the slide block inclined-plane, and slide block is slidingly connected on the claw inclined-plane of claw with its slide block inclined-plane.Said synchronous ring is contained in the dust cover inboard and is slidingly connected with dust cover, and synchronous ring is connected with slide block with bearing pin.Said fairlead is installed in the endoporus of chuck body.
Above-mentioned claw is that nine edges circumferentially are uniformly distributed with setting.
The slide block that above-mentioned claw connects is that nine edges circumferentially are uniformly distributed with setting.
The chucking oil cylinder that above-mentioned slide block connects is that nine edges circumferentially are uniformly distributed with setting.
The utility model is used for 5 1/2 " ~ 13 3/8 " (139.7mm ~ 339.7mm) oil pipe and gas thread processing; Centering precision height, length dimension precise control, chucking be safe and reliable, improved operating efficiency; Since directly be connected with main shaft, good rigidly, and precision is high; Good dustproof effect, long service life.
