It is stuck in corresponding rectangular channel, and be fixed together with support base 8 by bolt.
The processing jig of the present invention, also includes guide plate 4, and described guide plate 4 is slidably fitted in left support plate 5, right support
So that guide plate 4 can slide in vertical direction along left support plate 5, right support plate 2 between plate 2.For example, guide plate 4
Both sides are combined together by slide with the side wall of left support plate 5, right support plate 2 respectively, specifically real in invention one
Apply in mode, the side wall of described left support plate 5 is provided with the guide rail 50 along the distribution of its short transverse, described guide plate 4 is corresponding
Sliding tray with guide rail cooperation is provided with the wall of side, this guide rail 50 and sliding tray coordinate to realize the limit in x, y direction on horizontal plane
Position.With reference to Fig. 1, Fig. 4, in order to prevent guide plate 4 from the displacement in other directions occurring during vertical movement, guide rail 50 section is excellent
Select t-shaped or swallow-tail form, after its cooperation with sliding tray, can well the displacement in other directions for the restricted guidance plate 4 it is ensured that
The precision of guide plate 4.
Wherein, the side wall in described right support plate 2 is provided with the elongated through hole 20 along the distribution of its short transverse, described elongated
It is provided with the clamping screw 9 for locking guide plate 4, one end of clamping screw 9 passes through elongated through hole 20 and fixes in through hole 20
On the side wall of guide plate 4, and plate 4 is directed to by nut it is locked at desired position, the structure of clamping screw 9 belongs to existing
Technology, here no longer illustrates.
In the upper end of described left support plate 5, right support plate 2, upper mounted plate 1 is installed, this upper mounted plate 1 can pass through spiral shell
Silk 6 is directly anchored to left support plate 5, the upper end of right support plate 2, and fixed plate 1 is provided with multiple centre holes 11, is easy to push up
Pin penetrates, and wherein can also arrange datum hole 12, so that locating and machining.In one preferred embodiment of the invention, described
One end of upper mounted plate 1 be provided with for left support plate 5 side wall on guide rail 50 cooperation groove 10, this guide rail 50 and groove
The spacing of x, y direction on horizontal plane is realized in 10 cooperations.The other end of upper mounted plate 1 is screwed in the upper of right support plate 2
End.That is, one end of upper mounted plate 1 is against on the side wall of left support plate 5, and coordinated one by groove 10 and guide rail 50
Rise, the other end is directly fixed on the upper end of right support plate 2 by screw 6.Such structure design, can improve upper mounted plate 1
Installation accuracy, upper mounted plate 1 can be prevented to be subjected to displacement in the horizontal direction simultaneously.
Described guide plate 4 is also sliding combined with bottom plate 3 so that bottom plate 3 can edge in the horizontal direction
Guide plate 4 to slide.Wherein, with reference to Fig. 3, the lower end of described bottom plate 3 is provided with the first projection 30 of two strips,
Described first raised 30 position being connected with bottom plate 3 is formed with first step, the lower end of described first projection 30 and guiding
Plate 4 is slidably matched in the horizontal direction and carries out in terminal spacing, and the top surface of described first step is to the upper surface of guide plate 4
Distance is the height of thimble hanging platform, and wherein, centre hole 11 corresponds to the top of first step.In one specific embodiment party of invention
In formula, the lower end of described first projection 30 is provided with the second projection 31, is connected with first raised 30 in the described second projection 31
Position is formed with second step；Wherein, this second projection 31 is combined together with the guide groove 40 on guide plate 4 as guide rail, real
The now sliding matching structure of fixed plate 3 and guide plate 4.Guide groove 40 in the present invention preferably employs dovetail groove or t shape slot structure,
It is combined together it is ensured that the installation accuracy of bottom plate 3 with the second projection 31 of bottom plate 3, is also prevented from down simultaneously
There is the displacement in other directions in fixed plate 3.Described bottom plate 3 is provided with multiple centre holes, these centre holes are solid with upper
Centre hole 11 in fixed board 1 corresponds.Multiple centre holes can be in matrix distribution on upper mounted plate 1, bottom plate 3.And
And, penetrate the centre hole of upper mounted plate 1 for the ease of thimble, the centre hole 11 of fixed plate 1 lower end has the cone of expansion
Shape structure.
Thimble is pierced into centre hole from the bottom of bottom plate 3 by the processing jig of the present invention first, simultaneously by under thimble
The rotation stop side at end is fit together with the side wall of the first projection 30 in bottom plate 3, prevents thimble from rotating, thimble assembles it
Afterwards, bottom plate 3 is installed on guide plate 4 so that the second raised 31 of bottom plate 3 is joined with the guide groove 40 on guide plate 4
It is combined；Promote bottom plate 3 in the horizontal direction afterwards so that the thimble of thimble on bottom plate 3 and upper mounted plate 1
Align one by one in hole 11, vertically upward mobile guide plate 4, and guide plate 4 drives the thimble on bottom plate 3 and bottom plate 3 same
Walk and up move the centre hole so that thimble passes through upper mounted plate 1, and expose the upper end of thimble, be now directed to plate 4 again and lock
Get up, such that it is able to be machined out to the thimble upper end exposing centre hole 11.
The processing jig of the present invention, its structure is simple, assembling is convenient, only need to change correspondence to the thimble workpiece of different size
The upper bottom plate of specification.It is no longer necessary to organize the structures such as formwork erection core, mould bases, effectively reduce working strength, save
Installation time.This processing jig is lightweight, is easy to mobile, upper machine, improves the working (machining) efficiency of lathe.
In order to provide positioning to the displacement of bottom plate 3, make bottom plate 3 rapidly right with upper mounted plate 1
Should get up, the processing jig of the present invention, it is additionally provided with limiting plate 7, this limiting plate 7 is connected to described left support plate 5, right support plate
On the side wall of 2 the same sides.For example on left support plate 5, the side wall of right support plate 2 the same side, open up a mounting groove respectively, will limit
Position plate 7 is fixed in this mounting groove by the mode well-known to those skilled in the art such as screw.Connect left using limiting plate 7
Fagging 5, right support plate 2, can improve the installation strength of whole tool, it is also possible to provide positioning for bottom plate 3.Under
After fixed plate 3 and guide plate 4 are worked good, Level Promoting bottom plate 3, until the side wall of the side wall of bottom plate 3 and limiting plate 7
Fit together, now, bottom plate 3 is mapped with the centre hole in upper mounted plate 1, afterwards upwardly guide plate 4 again.
In the present invention, in order to reduce the contact area between bottom plate 3 and limiting plate 7, it is used for and limiting plate in described bottom plate 3
It is provided with multiple grooves, the plurality of groove can be distributed on the side wall of bottom plate 3 on the side wall of 7 laminatings.Certainly,
Contact area between bottom plate 3 and limiting plate 7 can be reduced using alternate manner well-known to those skilled in the art.
Although being described in detail to some specific embodiments of the present invention by example, the skill of this area
Art personnel it should be understood that example above is merely to illustrate, rather than in order to limit the scope of the present invention.The skill of this area
Art personnel are it should be understood that can modify to above example without departing from the scope and spirit of the present invention.This
