Description
Technical field
The present invention relates in the machining frock of auto parts machinery, specifically a kind of special-purpose vehicles of four loops valve body porous
Cut frock.
Background technology
Four loop valve bodies be it is a kind of full car gas circuit be divided into into four not only connected each other but also separate loop, when any one
When individual loop is broken down, other loop normal works are not affected with inflation.Under normal circumstances, four loop valve bodies are actually
It is a five-way joint, only certain primary Ioops occurs just to shield during disconnected, leakage failure.
In general, 4 holes on four loop valve bodies generally require when being processed 4 sub-folders tool come successively to each hole
Position carries out positioning and clamping turning.Using very inconvenient, efficiency is relatively slow for this mode, and after four loop valve bodies processing its 4
The axially in parallel degree in individual hole is relatively poor, affects product processing quality.
It is for the defect of existing this porous turning tool, public in Chinese utility model patent CN203003548U description
Opened a kind of highly effective vehicle clamper for indexing car hole, by fixed disk, clamp body, T-shaped pressing plate, briquetting, latch spring, insert
Pin and lock-screw are constituted.The clamp body is located at the clamp body transitional pore and clamp body location hole of one eccentric throw of fixed disk upper band
It is interior, laterally zygomorphic two indexing location hole is provided with clamp body transitional pore, lock-screw clamps workpiece, T-shaped pressure by briquetting
Plate locking fixture body, latch is coordinated with indexing location hole realizes indexing car hole function.When the complete automobile air-conditioning heating power of turnery processing it is swollen
After swollen valve body return-air hole, as long as unscrewing T-shaped pressing plate, latch is pulled up, clamp body is rotated into 180 °, then latch is inserted into another
Indexing location hole, then fastens T-shaped pressing plate, you can rapid turnery processing valve body air inlet.
In the middle of above-mentioned patent, can actually be played by way of being clamped after eccentric rotary again and be had with regard to energy by a sub-folder
The turning of porous, and simple structure are completed enough, simple structure is easy to operate, low cost of manufacture, production efficiency is relative to be obtained
Improve.But it is on the whole, due to being only that the valve body workpiece for asking for turning is passed through installing hole location and installation, this coarse
Positioning mode, easily briquetting clamp valve body when, easily cause valve body and deflection occur, cause partially to the particular location of hole machined
Difference.On the other hand, when carrying out changing hole turning, clamp body needs people by trickle manual after rotating a certain angle
Latch can be inserted after match by the indexing location hole on the fastening hole on clamp body and fixed disc will
Holes is connected, so as to complete the fixation of clamp body.This positioning mode is time-consuming relatively more long, once the hole of required turning excessively will
Bother very much.
The content of the invention
The base of the eccentric rotary clamping function having in above-mentioned technology for the defect existing for above-mentioned technology, the present invention
On plinth, when further improving hole site machining accuracy and accelerating to change hole turning, a kind of four loops valve body porous of speed is special
Use turning tool.
A kind of Special purpose turning frock of four loops valve body porous, mainly including chassis, rotating disk, clamp body, rotational positioning dress
Put and rotating clamp, chassis upper surface center is sequentially provided with placement circular groove from top to bottom, rotates circular groove.
The rotating disk is arranged on by rolling bearing to be placed inside circular groove, and the rotating disk circular shaft end is evenly equipped with four with rotation
The corresponding spill spin block of circular groove.
The rotating clamp includes two cylinders installed in chassis upper surface near circumference edge, the cylinder
Upper end is hinged with pressing plate, and the pressing plate is fixed with briquetting on the lower surface of center of turntable one end, the pressing plate with cylinder
Junction and the hinged block for being welded on chassis upper end is hinged with and the junction of briquetting between on position.
Aforesaid way is that mode of the prior art employed in clamps turning porous mode by eccentric rotary, works as needs
When carrying out changing hole turnery processing, it is only necessary to cylinder is pushed down on pressing plate by briquetting by the shape being pressed in disc surfaces originally first
State departs from, and then manually by 90 degree of turntable rotation, then cylinder is pushed down on pressing plate so that briquetting moves downward compression rotating disk.
Slot is equipped between the two neighboring spill spin block.
The chassis upper surface is provided with and rotates the locating slot that circular groove is communicated.
The rotary positioning apparatus include the riser for being vertically installed at locating slot top side, and the riser is provided with U-shaped
Groove, the riser upper end are welded with spring base, and the locating slot inner vertical is placed with the latch in one slot of insertion, institute
Stating that latch top is welded with the side of the riser position can be described to insert in the pull handle of longitudinal sliding motion in the U-lag
Pin upper surface is connected with the spring being fixedly mounted on spring base lower surface.
Said apparatus structure is one of main improvement of the present invention, and the positioning for being mainly used in changing during the turnery processing of hole is used
When, it is only necessary to manual-up pulling pull handle, cause engaging of the latch bottom with slot to depart from, whole latch is moved upwards by spring
Compression, while pull handle is held, manual slow rotary turnplate, when rotating disk 2 is rotated by 90 °, under the action of the spring, under latch
Portion can spring force effect under automatic fastening in slot corresponding on rotating disk 2.This positioning mode is comparatively more
Quickly, shorten the time for changing hole.
The clamp body includes the valve body positioning case for being fixedly mounted on rotating disk upper surface center, and the valve body positions one, case
The center of end wall is hinged with compact heap, and the positioning case is at the opposite flank outer end with compact heap hinged place to installation
There are clamping cylinder one, clamping cylinder two.
Said apparatus structure for the main improvement of the present invention two, is mainly reflected in and is incited somebody to action by cylinder one, clamping cylinder two
Compact heap coordinates clamp body to clamp hole to be processed, so as to ensure that being accurately positioned for hole turning.
Two center of arc's distance of the U-lag is equal with socket depth.Ensure that latch being capable of accurate and effective control rotating disk
Braking.
The invention has the beneficial effects as follows：
The present invention is employed on the basis of existing frock completes porous Technology for Turning Machining by eccentric rotary clamping
Rotating disk often turn 90 degrees spring automatically latch is pressed in slot and carries out single hole machined positioning, for prior art,
Easy to use, locating speed also saves manpower soon.Cylinder drive compact heap cooperation valve body positioning case will be each on valve body in addition
The tight mode of individual pore pressure to be processed will cause hole to obtain more accurately location positioning, further reduce the position of hole turning
Deviation, it is ensured that the axially in parallel degree in 4 holes.
