Abstract
The invention discloses a hydraulic chuck, which belongs to the field of chucks, and comprises a chuck seat, a seat plate and a chuck jaw, and further comprises an air cylinder, rollers, a rotating plate and a connecting rod, wherein an air cylinder piston rod is connected with the seat plate and a pressing wheel frame, the rollers are clamped through the seat plate and the pressing wheel frame, the chuck seat is connected with the rotating plate, the rollers are rotatably connected with the rotating plate, the chuck jaw is arranged on one end of the rotating plate and is hinged with the rotating plate, and the two ends of the connecting rod are respectively hinged with the chuck seat and the chuck jaw. The hydraulic chuck is simple in structure, excellent in automatic centering effect, reliable in performance and excellent in machining technique.
Description
Technical field
The present invention relates to chuck field, be specifically related to a kind of oild chuck.
Background technology
Chuck lathe is used for the mechanical device of clamping work pieces.Utilize and be distributed on moving radially of movable jaw on chuck body, the machine tool accessories of Workpiece clamping and location.Chuck is generally by chuck body, and movable jaw and claw drive three part compositions.There are through hole in chuck central authorities, so that by workpiece or bar, there is cylindrical or short taper profile structure at back, directly or be connected by ring flange and machine tool chief axis end.Wherein oild chuck can be divided into two kinds of structures a kind of is the oild chuck of forward type and chuck and rotary cylinder integration, and this installations is simple and convenient, and price economy is economical.Be that oild chuck and the chuck of rear pull type is installed on a lathe spindle front end, rotating hydraulic cylinder is installed on lathe spindle rear end.In recent years, along with engineering truck gets more and more, the giant tire changer of dismounting engineering vehicle tyre is come out one after another, and chuck is the critical component of changer, and effect is used to the wheel rim propping up wheel, to carry out dismounting operation.But existing chuck structure is complicated, and self-centering effect is poor, and performance is also unreliable.
Summary of the invention
Object of the present invention is providing a kind of structure simple, and self-centering effect is good, dependable performance, the oild chuck that processing technology is good.
For achieving the above object, technical scheme of the present invention is as follows: a kind of oild chuck, comprises chuck seat, seat board and chuck jaw, cylinder, roller, rotor plate and connecting rod; Described cylinder piston rod is connected with seat board and pinch roller frame, and described seat board and pinch roller frame clamp roller, and described chuck seat is connected with rotor plate; Described roller and rotor plate are rotationally connected, and described chuck jaw is arranged on rotor plate one end and hinged with rotor plate; Cylinder piston rod is connected with pinch roller frame successively with seat board, and two other hole of rotor plate is connected with chuck seat and chuck jaw with bearing pin respectively; Described connecting rod two ends respectively with chuck seat and chuck jaw hinged.
When doing axially-movable under the effect of piston rod at hydraulic pressure, drive roller not only along chuck axis to but also along chuck radial motion, in fact roller is the Fixed-point Motion of A around chuck seat, namely rotor plate under the drive of roller around the Fixed-point Motion of A of chuck seat, chuck jaw under the drive of rotor plate simultaneously again by connecting rod restriction not only along chuck axis to but also along chuck radial motion, ensure that chuck jaw reliably props up object.Structure of the present invention is simple, and self-centering effect is good, dependable performance.
Further, described chuck seat and rotor plate are bolted, bolt dismounting easy to connect and couple together conveniently.
Further, described chuck jaw has three, and three can well fixed tire, and more stable.
Further, described connecting rod and chuck seat are by pinned connection, easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of oild chuck embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: 1-piston rod; 2-seat board; 3-roller; 4-chuck seat; 5-bearing pin; 7-rotor plate; 8-pinch roller frame; 9-connecting rod; 10-nut; 11-chuck jaw.
Embodiment is substantially as shown in Figure 1: a kind of oild chuck, comprises cylinder, seat board 2, roller 3, chuck seat 4, rotor plate 7, pinch roller frame 8, connecting rod 9 and chuck jaw 11; Rotor plate 7 two ends are offered porose, seat board 2 and pinch roller frame 8 clamp roller 3, roller 3 two ends penetrate in the hole of rotor plate 7, and cylinder piston rod 1 is connected with pinch roller 8 successively with seat board 2, and two other hole of rotor plate 7 is connected with chuck seat 4 and chuck jaw 11 with bearing pin 5 respectively; Connecting rod 9 and chuck seat 4 and chuck jaw 11 hinged.Chuck seat 4 and rotor plate 7 are bolted, bolt dismounting easy to connect and coupling together conveniently.Chuck jaw 11 has three, three can be stable fixed tire.Connecting rod 9 is connected with chuck seat 4 by bearing pin 5, bearing pin 5 dismounting easy to connect, easy to assembly.When doing axially-movable under the effect of piston rod 1 at hydraulic pressure, drive roller 3 not only along chuck axis to but also along chuck radial motion, in fact roller 3 is the Fixed-point Motion of As around chuck seat 4, namely rotor plate 7 under the drive of roller 3 around the Fixed-point Motion of A of chuck seat 4, chuck jaw 11 under the drive of rotor plate 7 simultaneously again by connecting rod 9 restriction not only along chuck axis to but also along chuck radial motion, ensure that chuck jaw 11 reliably props up object.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
