Abstract
A kind of speed-changer operation lid drilling-hole positioning device, it is characterised in that：Including base, cylindrical positioning pins, diamond positioning pin, positioning sleeve, screw rod, spacer, opening pressing plate, locking nut, screw, positioning sleeve is fixed by screws on base, on diamond positioning pin and the symmetrical positioning sleeve of cylindrical positioning pins, cylindrical positioning pins are fixed on positioning sleeve by base, positioning sleeve flat shape is the boss of four deciles, through screw rod, spacer in positioning sleeve, load onto workpiece to be processed and manipulate lid, then load onto opening pressing plate and locking nut on screw rod workpiece can be manipulated into lid and fixed.The utility model changes the contact area of locating surface, takes the mode of four point positioning, by locating and machining face being made into the boss of the quartering, solves the problem of position error influences processing caused by aluminium skimmings are adhered to locating surface, causes mismachining tolerance.With reference to the mode of two finger settings, processing is simple, and positioning is reliable, is advantageous to chip removal and cleans aluminium skimmings, improves crudy.
Description
Technical field
It the utility model is related to a kind of speed-changer operation lid drilling-hole positioning device.
Background technology
Speed-changer operation lid needs to process the dowel hole of an axial direction, and the position accuracy demand in hole is higher, does not reach essence
Degree can influence shift property, and serious meeting causes gear shift clamping stagnation.Generally processing is drilled again with fitting surface positioning, because manipulating lid material
Expect for aluminum often there is the positional precision that aluminium skimmings attachment causes fitting not influence drilling sternly, such as hole when fitting surface is bonded with frock
Position is bored can influence gearbox gear-shift action partially, and transmission assembly can not be qualified offline.
The content of the invention
The purpose of this utility model is to provide a kind of speed-changer operation lid drilling-hole positioning device, overcomes original locating and machining
Face Full connected mode can be because of the position error caused by aluminium skimmings are adhered to locating surface the shortcomings that.
A kind of speed-changer operation lid drilling-hole positioning device, it is characterised in that：Including base, cylindrical positioning pins, rhombus positioning
Pin, positioning sleeve, screw rod, spacer, opening pressing plate, locking nut, screw, positioning sleeve are fixed by screws on base, and rhombus is fixed
On position pin and the symmetrical positioning sleeve of cylindrical positioning pins, cylindrical positioning pins are fixed on positioning sleeve by base, positioning sleeve plane
The boss of four deciles is shaped as, screw rod, spacer are passed through in positioning sleeve, workpiece to be processed is loaded onto and manipulates lid, then on screw rod
Lid can be manipulated by workpiece and fix by loading onto opening pressing plate and locking nut, tighten locking nut and workpiece is clamped, so far complete
Positioning, clamping into workpiece, carry out Drilling operation.
The utility model has the advantages that：By the four point positioning mode of positioning sleeve quartering boss, reduce speed-changer operation
The contact area of lid machined surface and positioning sleeve, two alignment pins are two kinds of shapes of diamond positioning pin and circular alignment pin, and rhombus positions
Pin can control the radial rotary of workpiece to ensure fit-up gap, while reliable location is ensured, ensure that fit-up gap, effectively
Ensure the positioning precision of workpiece and the machining accuracy of product.By reducing the contact area of shaft-cup machined surface and positioning sleeve, solve
Caused by aluminium skimmings are adhered to locating surface position error, cause the problem of mismachining tolerance.Pass through the four of two finger settings and positioning sleeve
Point location, the guiding and locating effect of workpiece is effectively ensured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 left side structure schematic view；
In figure：Base 1, cylindrical positioning pins 2, positioning sleeve 3, screw rod 4, spacer 5, screw 6, diamond positioning pin 7, be open pressing plate
8, locking nut 9.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of speed-changer operation lid drilling-hole positioning device, it is characterised in that：Including base 1, cylindrical positioning pins 2, positioning sleeve
3rd, screw rod 4, spacer 5, screw 6, diamond positioning pin 7, opening pressing plate 8, locking nut 9, positioning sleeve 3 are fixed on bottom by screw 6
On seat 1, on diamond positioning pin 7 and the symmetrical positioning sleeve 3 of cylindrical positioning pins 2, it is fixed that cylindrical positioning pins 2 are fixed on by base 1
On position set 3, the flat shape of positioning sleeve 3 is the boss of four deciles, passes through screw rod 4, spacer 5 in positioning sleeve 3, loads onto to be processed
Workpiece manipulates lid, then loads onto on screw rod 4 opening pressing plate 8 and locking nut 9 and workpiece can be manipulated into lid and fixed.Positioner work
When making, it would be desirable to which the speed-changer operation lid of processing loads positioning sleeve 3, and speed-changer operation lid mounting hole is aligned into diamond positioning pin 7
With cylindrical positioning pins 2, the locating surface of speed-changer operation lid is adjacent to the plane of positioning sleeve 3, and the flat shape of positioning sleeve 3 is four deciles
Boss.Load screw rod 4, spacer 5, opening pressing plate 8, opening pressing plate 8 compresses speed-changer operation lid, the opening shape for the pressing plate 8 that is open
The displacement of locking nut 9 can be reduced when installing part, realizes quick locking.After the positioning of speed-changer operation lid, tighten
Locking nut 9 is clamped to workpiece, is so far completed the positioning of workpiece, is clamped, proceeds by Drilling operation.
By the four point positioning mode of the quartering boss of positioning sleeve 3, reduce speed-changer operation lid machined surface and positioning sleeve 3
Contact area, two alignment pins are respectively 2 two kinds of shapes of diamond positioning pin 7 and circular alignment pin, and diamond positioning pin 7 can control change
The radial rotary that fast device manipulates lid ensures fit-up gap, while reliable location is ensured, ensure that fit-up gap, is effectively ensured
The positioning precision of workpiece and the machining accuracy of product.By reducing the contact area of shaft-cup machined surface and positioning sleeve, solve because of aluminium
Position error caused by bits are adhered to locating surface, the problem of causing mismachining tolerance.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, make some equivalent substitutes or obvious modification without departing from the concept of the premise utility, and performance or
Purposes is identical, then should be considered as belonging to the protection domain that claims that the utility model is submitted determine.
