Description
Technical field
The utility model belongs to Automatic manual transmission workpiece technical field, particularly a kind of air discharging manifold flange hole runner elastic floating locating taper pin.
Background technology
Automobile gas exhausting manifold branch zero product variety is many, and batch is large.In process, for ensureing that the position degree of product air inlet flange face installing hole and runner mouth is so that the installation of exhaust manifold and cylinder cap, boring initial alignment benchmark is typically chosen in air inlet flange runner, belong to blank location, but because casting deviation is larger, runner mouth diameter dimension size is unstable, if adopt stationary positioned finger setting, runner mouth diameter is little, product can not be fitted with tool positioning surface, runner mouth diameter is large, and runner mouth and fixed locating stud gap greatly, can not ensure the position degree requirement of Drilling operation hole when and runner mouth.
Summary of the invention
Main purpose of the present utility model is to work out that a kind of positioning precision is high, easy to manufacture, cost is low, stay-in-grade air discharging manifold flange hole runner locating taper pin.
For achieving the above object, technical solution adopted in the utility model is: air discharging manifold flange hole runner elastic floating locating taper pin, and described locating taper pin comprises guiding cap and holder, arranges spring between described guiding cap and described holder; The endoporus matched in clearance of described guiding cap and described holder, and fluctuated by described spring; Described lower spring end adopts circle block and circlip to be installed on described holder, and described guiding cap arranges keyway.
Described holder inside arranges lip dust ring.
Described holder arranges perforate, described perforate arranges holding screw, the keyway on described screw and described guiding cap matches.
Described guiding cap is arranged two locating surfaces, restriction both direction.
Described locating taper pin is fixed on rig fixture by flange screw.
The utility model in use, that guiding cap is mounted on clamp body by holder and clamp body flange screw, the endoporus matched in clearance of guiding cap and holder, and fluctuated by spring, lower spring end adopts circle block and circlip to be installed on holder, thus realize whole taper pin and up and downly can automatically realize workpiece and automatically locate, guiding cap is milled with keyway, can prevents locating taper pin from rotating and limiting up and down scope by holding screw.Holder inside is provided with lip dust ring, for seal lubrication and prevent iron filings foreign material from entering, avoids the taper pin stuck phenomenon in use occurred.
The beneficial effects of the utility model are:
(1) manufacture simply, precision is high, cost is low, can realize standardized production, has interchangeability advantage, can effectively reduce costs, and in adopting between holder and clamp body, hexagonal flange screw is installed and fixed, installation, convenient disassembly.
(2) guiding cap of locating taper pin adopts small―gap suture to coordinate with between holder endoporus, and install lip dust ring, have dustproof effect, iron filings, foreign material are difficult to enter in holder; Add oil lubricating in locating cone bearing pin and holder, lubrication is good, and frictional force is little, long service life simultaneously.
