Description
Technical field
This utility model relates to the Machining Technology field of punching block material, particularly a kind of porous punching block inner circle mill folder
Tool.
Background technology
In the grinding of porous punching block endoporus, used clamping method uses floral disc to add tailstock center and combines
Method carries out clamping and correction, as it is shown in figure 1,1 is the headstock, 2 is floral disc, and 5 is grinding tool, and workpiece 4 relies on pressing plate 3 to be pressed on floral disc
Above 2, by the thimble of tailstock workpiece 4 held out against above floral disc, carry out workpiece location, then by grinding tool on workpiece 4
Multiple endoporus are polished successively.
On above-mentioned technological method for processing, use tailstock center top tight workpiece, the most again workpiece is carried out pressing plate fastening, enter
And workpiece is carried out inner hole grinding processing, there is following defect in this kind of installation way:
One, production efficiency is relatively slow, and workpiece adds man-hour, single hole clamping minutes correction time about 2.5 in conversion position, hole.
Two, the method that have employed single hole location due to workpiece, have ignored the position degree relation of adjacent holes position, can cause work step
Between cumulative error strengthen.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that a kind of porous punching block inner circle mill folder
Tool, workpiece is easy and simple to handle during processing and loading clamp, workpiece change position, hole processing time the clamping time in 1 minute, efficiency obtains
To being effectively improved, use diplopore localization method simultaneously, reduce the position degree skew of work piece.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of porous punching block inner circle grinding jig, including Mohs clamp body, be additionally provided with in described Mohs clamp body front end for
The clamping hole of clamping workpiece, also includes gland, location key seat and alignment pin, if described Mohs clamp body front end edge is evenly distributed in
Dry bar axial shrinkage is stitched, and gland is connected by screw thread with Mohs clamp body front end, and location key seat is fixed on Mohs clamp body front end
Clamping hole in, alignment pin is vertically set in location key seat vertically, alignment pin end connect have by alignment pin jack-up keep
The compression spring of axial elasticity, the front end of alignment pin extends to outside Mohs clamp body front end.
Further, described shrinkage joint is set to 4.
For the ease of location workpiece, described alignment pin is set to two.
Preferably, described alignment pin front end is pyramidal structure.
Compared with prior art, the beneficial effects of the utility model:
1, this fixture is installed and regulates convenient to use, effectively raises porous punching block and is carrying out inner hole grinding processing
In clamping workpiece efficiency, use this fixture substantially can reach the clamping workpiece time than existing installation way save the time two points
More than one of.
2, use unique workpiece location mode, efficiently solve the position degree cumulative errors that clamping workpiece process produces,
Finished product qualification rate improves more than 5%.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art fixture；
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by specific embodiment, in the signal of this utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as restriction of the present utility model.
A kind of porous punching block inner circle grinding jig as shown in Figure 2, including Mohs clamp body 1, in Mohs clamp body 1 front end also
It is provided with the clamping hole 7 for clamping workpiece, also includes gland 2, location key seat 3 and alignment pin 5, Mohs clamp body 1 front end edge circle
Being evenly equipped with 4 axial shrinkage seam (not shown in FIG.) week, gland 2 is connected by screw thread with Mohs clamp body 1 front end, location key seat
In the 3 clamping holes 7 being fixed on Mohs clamp body 1 front end, alignment pin 5 is vertically set in location key seat 3 vertically, alignment pin 5
Being set to two, alignment pin 5 front end is pyramidal structure, and alignment pin 5 end connects to be had alignment pin jack-up holding axial elasticity
Compression spring 4, the front end of alignment pin 5 extends to outside Mohs clamp body 1 front end, is additionally provided with use in described Mohs clamp body 1 front end
Clamping hole 7 in clamping workpiece 6.The gland 2 that turns clockwise makes gland 2 axially be moved to the left and forces Mohs clamp body 1 front end
Inclined-plane pressurized and produce radial contraction and workpiece 6 clamped, the front end, clamping hole 7 that workpiece 6 is clamped on Mohs clamp body 1.
During operation, the Morse taper shank of Mohs clamp body 1 is loaded in internal grinder mohs tapered bore, and strains with wire drawing bar,
Rotating gland 2 counterclockwise, Mohs clamp body 1 clamps hole 7 and opens by elastic clear-cutting forestland, any holes on workpiece 6 is directed at
Two alignment pins 5 axially inward propelling movement hold out against on Mohs clamp body 1, and workpiece 6 is clamped by the gland 2 that turns clockwise
Carrying out the grinding of inner hole of workpiece, after workpiece 6 completion of processing, only need to take out workpiece 6 radially rotates suitable angle, reorientates
Clamping workpiece 6.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, within each falling within protection domain of the present utility model.
