Description
Technical field
The utility model 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 lathe and carry out the machining of part.General lathe with device be three-pawl type claw, can play good fixation for this claw of the processing parts with axle center symmetry.But for some irregular special-shaped parts, this claw cannot use.Prior art is fixing for special-shaped part, and normally the fixture of design specialized replaces claw.Although can play fixing effect, cost of manufacture is high, disassembly and assembly time is long, has greatly improved the processing cost of special-shaped part.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of special-shaped workpiece clamping tooling, can improve the deficiencies in the prior art, by the clamping tooling of design 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, technical solution adopted in the utility model is as follows.
A kind of special-shaped workpiece clamping tooling, comprise tubular outrigger, on tubular outrigger, be 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 the axial direction along tubular outrigger is arranged in order, the bottom surface of arc-like sheet is provided with the first jut and the second jut, in the middle of the first jut and the second jut, be provided with fast pulley, between fast pulley and arc-like sheet, be provided with the first nonrigid connector, the 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, the first anti-skidding striped and the vertical setting mutually of the second anti-skidding striped.
As preferably, the arc angle of described arc-like sheet is 120 °.
As preferably, the top of described the 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 the 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 hangnail, and the two ends of fixed cover are provided with larynx hoop.
As preferably, between described metal hangnail and described the first nonrigid connector, be connected by the second nonrigid connector.
The beneficial effect that adopts technique scheme to bring is: the utility model is socketed on the original claw of lathe by fixed cover, and metal hangnail has improved the degree of being connected firmly of fixed cover and claw, and finally fixing by larynx hoop, easy accessibility.Three arc-like sheets that are 120 ° are fixed workpiece at different horizontal levels, can keep the stable of workpiece, and can be fixed for various special-shaped workpieces.The 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, the clamping stability that can avoid excessive difference in height to cause.Fixed claw can be realized the fixing of former and later two directions, has improved 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, has improved the stability to special-shaped workpiece.Vertical settings mutually of the first anti-skidding striped and the second anti-skidding striped, improved special-shaped workpiece axially with fixing radially, avoided the micro-play of part in process.The deformation that metal hangnail produces in the time of stationary jaw is passed to the first nonrigid connector by the second nonrigid connector, and the deformation producing can utilize metal hangnail fixing to claw time feeds back to the first nonrigid connector, changes the clamping dynamics of fast pulley, puies forward stability.
