Description
Technical field
The invention belongs to field of machining, more particularly to boring grab on pull-fork assembly.
Background technique
Pull-fork assembly is usually used in gear-box, is a common part in gearshift comprising shift fork and shift fork axle,
Shift fork axle is fitted into shift fork through-hole, is all drilled with dowel hole on shift fork axle and shift fork, and two parts are fixed after squeezing into pin,
And require shift fork arc surface axis after fixing corresponding to the plane and shift fork axle mounting plane angle satisfaction that shift fork axle axis forms
It is required that.According to Conventional processing methods, needs first first to beat dowel hole on the through-hole periphery of shift fork, then shift fork axle is packed into and is dialled
It pitches in through-hole, the relative position of two parts is adjusted to after meeting the requirements, then with dowel hole in brill shift fork axle, or pass through shift fork
Dowel hole gets sample dotting punch in shift fork axle, then drills to axis.This to the more demanding and time-consuming more of operator,
To which product quality hardly results in guarantee, working efficiency is low, and labor intensity is high, is not suitable for high-volume and processes.
Summary of the invention
The present invention is to solve technical problem present in well-known technique and provide that bore dowel hole on a kind of pull-fork assembly special
With fixture, positioning and clamping is carried out using the fixture, energy clamped one time accurately guarantees that shift fork is met the requirements with shift fork axle relative position
Under, the dowel hole processing on two parts is completed, and clamping is simply easily operated.
Dowel hole special fixture, including pedestal, positioning device, clamping device and drill jig dress are bored on a kind of pull-fork assembly
It sets, it is characterised in that: have the vertical plate with shift fork shaft mounting hole and positioning device mounting hole on the pedestal；The positioning device with
Vertical plate connection, has the locating piece with arc surface thereon, fork can be navigated to the angle of needs；The clamping device includes branch
Fagging, gripping block are installed in the band cular arc groove of support plate, and move along guide ledges, and force-application block drives backspin in handle
When turning, gripping block can be pushed to carry out clamping to the plane in shift fork axle by adjusting screw；The drill jig device is connected to bottom plate
On, there is the drill guide for meeting bore position requirement thereon.
The advantages and positive effects of the present invention are:
It by adopting the above technical scheme due to the present invention, can clamped one time completion when carrying out clamping to pull-fork assembly using the fixture
The drilling processing of dowel hole on two parts, and the mutual position accuracy of two parts can preferably be guaranteed by fixture, be subtracted
Lack the factor of manual operation, and clamping is simple, it is easily operated, the efficiency of hole machined greatly improved, reduce operator's
Labor intensity is high, processes high-volume and is easily achieved.

Specific embodiment
For that can further appreciate that innovation and creation contents, features and effects of the invention, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing:
It please refers to Fig. 1-5, bores dowel hole special fixture, including pedestal 1, positioning device 2, clamping device on a kind of pull-fork assembly
3 and drill jig device 4.
Include vertical plate 11, bottom plate 12 on the pedestal 1, shift fork shaft mounting hole 111, positioning device peace are machined on vertical plate 11
Fill hole 112.
The positioning device 2 includes locating piece 21, connecting shaft 22,21 on locating piece on have arc surface 211, and be used for
The through-hole that connecting shaft 22 is installed, connecting shaft 22 are that stairstepping axis, connecting shaft 22 and locating piece 21 are connected by the interference fit of axis hole
It is connected together, 22 other end of connecting shaft is inserted into the positioning device mounting hole 112 of vertical plate 11, and fixed by holding screw 23.
