Description
Technical field
The present invention relates to Machining Technology field, especially a kind of special-shaped workpiece clamping tooling.
Background technology
In the mechanical processing process of part, usually need to use the machining that lathe carries out part.General lathe with device be three-pawl type claw, good fixation can be played for this claw of the processing parts of axle center symmetry.But for some irregular special-shaped parts, this claw then cannot use.Prior art fixing for special-shaped part, normally the fixture of design specialized replaces claw.Although can play fixing effect, cost of manufacture is high, and disassembly and assembly time is long, substantially increases the processing cost of special-shaped part.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of special-shaped workpiece clamping tooling, can improve the deficiencies in the prior art, by designing the clamping tooling of general-purpose type, realize directly socket use on the original claw of lathe, flexibly and easily, can be mass-produced, cost is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of special-shaped workpiece clamping tooling, comprise tubular outrigger, tubular outrigger is hinged with three connecting rods, the top of connecting rod is hinged with drive link, the top of drive link is provided with fixed cover, the bottom of connecting rod is hinged with arc-like sheet, three arc-like sheets are arranged in parallel, and be arranged in order along the axial direction of tubular outrigger, the bottom surface of arc-like sheet is provided with the first jut and the second jut, fast pulley is provided with in the middle of first jut and the second jut, the first nonrigid connector is provided with between fast pulley and arc-like sheet, first nonrigid connector is arranged in arc-like sheet, the height of the first jut is higher than the height of the second jut, the surface of the first jut and the second jut is provided with the first anti-skidding striped, the surface of fast pulley is provided with the second anti-skidding striped, first anti-skidding striped is arranged with the second anti-skidding striped is mutually vertical.
As preferably, the curved angle of described arc-like sheet is 120 °.
As preferably, the top of described first jut and the second jut is symmetrically arranged with outward-dipping fixed claw.
As preferably, the angle of inclination of described fixed claw is 15 ° ~ 30 °.
As preferably, described first jut is 3:2 with the ratio of the height of the second jut.
As preferably, the inside of described fixed cover is provided with metal barb, and the two ends of fixed cover are provided with larynx hoop.
As preferably, be connected by the second nonrigid connector between described metal barb with described first nonrigid connector.
The beneficial effect adopting technique scheme to bring is: the present invention is socketed on the original claw of lathe by fixed cover, and metal barb improves the degree of being connected firmly of fixed cover and claw, and is finally fixed by larynx hoop, easy accessibility.Three are fixed workpiece at different horizontal levels in the arc-like sheet of 120 °, can keep the stable of workpiece, and can be fixed for various special-shaped workpiece.First jut and the second jut can utilize the fluctuating of special-shaped work piece surface to connect and fix, and the ratio of its height is preferably 3:2, can avoid the clamping stability that excessive difference in height causes.Fixed claw can realize the fixing of former and later two directions, improves the first jut and the second jut adaptability for special-shaped work piece surface.Fast pulley can utilize the deformation quantity of the first nonrigid connector to fill up fixing to the space between the first jut and the second jut, improves the stability to special-shaped workpiece.First anti-skidding striped is arranged with the second anti-skidding striped is mutually vertical, improve special-shaped workpiece axially fixing with radial, avoiding the micro-play of part in process.The deformation that metal barb produces when stationary jaw is passed to the first nonrigid connector by the second nonrigid connector, and the deformation produced when metal barb can be utilized to fix claw feeds back to the first nonrigid connector, changes the clamping dynamics of fast pulley, puies forward stability.
