Description

Interior chip removal is stretched gapless positioner

Technical field

This utility model relates to machining manufacture, the detent mechanism of frock clamp shell part.Particularly There is the coarse positioning of quickly feeling relieved of the product in hole, location, it is achieved the gapless positioner of empty end face, and guarantee Add the unimpeded interior chip removal of chip removal in man-hour at inner via hole to stretch gapless positioner.

Background technology

The housings such as current automotive transmission, use aluminum alloy die-casting technological to carry out the molding of blank, casting mostly When making, mould has certain casting draft, and when actual casting, blank also has a certain degree of change Shape, and mould the most also has abrasion deformation, these all can cause casing blank to there is different journey The deformation of degree, in the past when blank first working procedure positions, selects the privileged sites of blank shape to carry out slightly mostly Location, or select the core-drawing hole that some are bigger to position, but the housing bore position after processing due to the error of foundry goods Having dislocation with blank, affect outward appearance, the allowance additionally, due to die casting is the most less, positions meeting improperly Cause certain this position surplus deficiency to cause to scrap, if as the hole of coarse positioning, because mould uses process, Fracture of loosing core does not casts out, then cannot be carried out in location and processing.

Utility model content

For overcoming the housing part improper impact that processing is caused of processing first working procedure blank coarse positioning, this practicality Novel one simple in construction, the registration gapless of providing, and can stretch with the interior chip removal that chip removal is unimpeded Gapless positioner.

In a kind of, chip removal is stretched gapless positioner, and including positioning seat and pedestal, positioning seat passes through with pedestal Built-in spring floating couples, and positioning seat side opening has the angular cut for chip removal, described positioning seat lower outside With pedestal upper outside joining place equipped with guard ring.

Preferably, the angular cut of described positioning seat is up big and down small tapered configuration, and aperture is the circle of R3-R5 Arc transition.

Further, be provided with in described pedestal fluted under have the spring base of boss, described base bottom sets Having through hole, boss embeds in the through hole of pedestal.

Further, described spring is arranged in groove, and spring is arranged over locating piece, and locating piece is placed in base In locating slot inside Zuo.

Further, pedestal also includes hexagon socket head cap screw, screw bolt passes spring base, spring and limited block Through hole, leave space between top and the positioning seat of bolt.

Further, described space height is less than the impulse stroke of spring.

This utility model uses the interior chip removal of combining form to stretch integrated positioning holder structure, and base interior is provided with Spring, in order to eliminate deformation and the draft of blank, it is ensured that it is fixed that positioning seat end face and workpiece are in gapless Position, positioning datum is selected in inner chamber, the axis of the periphery of bigger cylindrical hole, and the inner chamber end face in this hole, And choose deflection casing center position, variator fore shell is chosen the periphery in clutch release bearing carrier hole Axis and end face as benchmark, process chip removal inclined-plane in positioning seat bottom, it is ensured that processing endoporus time row Consider to be worth doing unimpeded.Positioning seat lower outside equipped with guard ring, prevent cutting fluid, aluminum bits etc. splash enter positioning seat and Sliding position between pedestal, causes clamping stagnation.Positioning seat upper surface and circumference are made round-corner transition and are conducive to conveniently Workpiece mounting or dismounting.Space height prevents spring fatigue from can not reset.

The beneficial effects of the utility model are:

1, the stretching structure of positioning seat can realize the location of the gapless to blank；

2, distinctive chip removal inclined-plane, makes inner via hole add and is constantly discharged downwards by processing aluminum bits, it is ensured that processing man-hour The quality in face；

3, positioning seat lower outside is equipped with guard ring, it is ensured that positioning seat is in use without clamping stagnation；

4, manufacturing process is simple, low cost；

5, change conveniently, only Foundation anchor bolts is pulled down, during installation, spring base lower boss is directed at Position hole on base plate, tighten Foundation anchor bolts the most permissible；

6, clamping is easy, and labor strength is low, is suitable for streamline processing；

7, owing to selecting big cylinder location, and can automatically eliminate gap, location, be advantageously implemented mechanical hand automatic Operation.

Detailed description of the invention

With reference to Fig. 1, a kind of in chip removal stretch gapless positioner, including positioning seat 1 and pedestal 3, location Seat 1 and pedestal 3 are by built-in spring 6 Floating connection, and positioning seat 1 side opening has the angular cut for chip removal, Positioning seat 1 lower outside and pedestal 3 upper outside joining place are equipped with guard ring 2.It is provided with in pedestal 3 Having the spring base 7 of boss, pedestal 3 bottom to be provided with through hole under groove, boss embeds in the through hole of pedestal 3. Spring 6 is arranged in groove, and spring 6 is arranged over locating piece, and locating piece is placed in the location inside pedestal 3 In groove.Pedestal 3 also includes that hexagon socket head cap screw 4, bolt 4 sequentially pass through spring base 7, spring 6 and spacing The through hole of block 5, leaves space between top and the positioning seat 1 of bolt 4.Space height is less than spring 6 Impulse stroke.

Up big and down small tapered configuration is made in hole, location, positioning seat 1 top, its tapering and positioned blank cylindrical Tapering is consistent, and ensures to make blank cylindrical can be in the appropriate location of positioning seat 1, and angular cut is made R3-R5 Arc transition, be beneficial to position centering.Positioning seat 1 bottom uses with pedestal 3 and is slidably matched, and coordinates public affairs Difference can be selected for H7/g6, and surface uses grinding, to ensure that use process is without clamping stagnation.

Positioning seat 1 bottom uses close-fitting mode to install guard ring 2, and guard ring 2 bottom is in use All the time pedestal 3 top can be included in inside, during to prevent work pieces process, aluminum bits fly into sliding position.

After positioning seat 1 loads pedestal 3, it is combined with limited block 5 and screw, prevents positioning seat 1 upwards Pull-out, it is internal that spring 6 is arranged on pedestal 3, and lower springs seat 7 cylindrical coordinates with spring 6 hole, spring base 7 lower ends have boss to coordinate with base plate, it is ensured that the location during dismounting of whole alignment system.

Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although reference This utility model has been described in detail by previous embodiment, it will be understood by those of skill in the art that it Still the technical scheme described in previous embodiment can be modified, or to wherein portion of techniques feature Replace on an equal basis；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this practicality The spirit and scope of novel each embodiment technical scheme.
