Abstract
The utility model discloses a kind of lamp outer casing Special Fixture for Machining, comprise orientational cone-shaped surface, be installed axle, disk, locking nut, support, location-plate, Workpiece fixing taper hole and clamping screw, the be installed setting circle conical surface of axle of described fixture is assemblied in lathe spindle tapered hole, 3 claws of lathe three-claw chuck clamp the axle cylindrical that is installed, the assembling positioning precision of integral clamp is checked according to the disk of fixture, in the location tapered hole that the tapering cylindrical of 2 of workpiece wiring mouths is injected fixture simultaneously and pilot hole, the reach of turn locking nut makes its end face contact with workpiece end face and lock, one of them wiring mouth endoporus of workpiece and internal thread are processed, unclamp after locking nut makes it and move, promote workpiece along gathering sill transverse horizontal after the taper hole of workpiece pull-off fixture location and make another unprocessed workpiece wiring mouth inject location taper hole, after locking, continue processing.The utility model is cheap for manufacturing cost, have self-centering function, without the need to adjusting centering and easy to operate.
Description
Technical field
The utility model relates to technical field of lamps, particularly relates to a kind of lamp outer casing Special Fixture for Machining.
Background technology
Flameproof luminaire shell to there is the wiring mouth of helical structure needed for turnover power line.Wiring mouth on flameproof luminaire Al-alloy casing foundry goods is generally symmetricly set on the both sides of housing or is eccentrically set on same end face, uses conventional clamp processing wiring mouth endoporus and internal thread thereof to have certain difficulty.Can not meet the needs of mass production according to conventional clamp card engaging workpiece and complicated operation, adjustment difficulty, workpiece time that is installed is long.
Utility model content
According to above deficiency, the utility model provide a kind of structure simple, cheap for manufacturing cost, there is self-centering function, without the need to adjusting centering and safe and efficient lamp outer casing Special Fixture for Machining.
For achieving the above object, the utility model lamp outer casing Special Fixture for Machining, main contents are: comprise orientational cone-shaped surface, be installed axle, disk, locking nut, support, location-plate, Workpiece fixing taper hole and clamping screw, it is characterized in that: described in axle 45 round steel that are installed be processed into, the orientational cone-shaped surface matched with lathe spindle taper hole is processed in the rear end of the described axle that is installed, described orientational cone-shaped surface is the positioning datum of whole fixture, described disk is welded on support left end, described location-plate is welded on support right-hand member, described clamping screw is the right-handed thread compared with coarse pitch, be conducive to the Quick fastening of workpiece and unclamp, described locking nut front end has the disk of larger area to coordinate the locking device formed workpiece with bolt, clamping screw described in two is arranged in disc centre hole, described locking nut is arranged on clamping screw, described location-plate center is processed with Workpiece fixing taper hole.
As preferably, described clamping screw is processed into the single line trapezoidal thread of 4mm pitch, has that precession speed is fast, coupling mechanism force large and durable wear-resistant high.
As preferably, described location-plate processes the Workpiece fixing taper hole of a workpiece wiring mouth with the axle coaxial center position that is installed, and its taper hole gradient is identical with workpiece wiring mouth pattern draft ensures accurate work piece positioning with this.
As preferably, the gathering sill of described location-plate rear end processing certain depth, workpiece moves horizontally the Working position changing workpiece wiring mouth along gathering sill.
The effect that the utility model is useful is: plug-in type conical surface integrated structure, and workpiece more moves forward cooperation can be tighter. this structure effectively prevent the unsafe factor that in process, workpiece easily loosens and workpiece flies out; Decrease locking step, install workpiece rapidly, locking is firm, clamping force is even, safe and reliable, shorten the fastening time, effectively improves operating efficiency.
