Description
Technical field
The utility model relates to a kind of fixtures, in particular to for a kind of abnormal workpieces of the support base boring inner hole of fork truck
Semicircle orifice bore hole clamping apparatus.
Background technique
There are three major defects in the semicircle orifice of workpiece working special-shaped on numerically controlled lathe for existing fixture: 1. fixtures pass through three
For dog chuck in conjunction with lathe, suspending weight is excessive, and when work is also easy to produce the effect of jitter speed of mainshaft；2. using two workpiece semicircle complementary pairs
The mode of processing is pasted, clamping workpiece needs first to be inserted into fixture midline position with baffle, and workpiece half nose circle face paste is leaned on baffle, workpiece
Side, which reclines, chuck side locating piece and again takes out baffle after locking, the half of workpiece one before another workpiece again and again reclines semicircle end face
Nose circle face, side surface of workpiece recline and lock after chuck side locating piece.But since baffle can have skew because gap is excessive caused by abrasion
Loosening problem, influences machining accuracy；3. above-mentioned fixture side locating piece is strip, when debugging between two locating piece of expense table school
Away from and it is horizontal, and need adjustment again after wearing, it is cumbersome.Therefore this fixture machining accuracy it is unstable, and production efficiency compared with
It is low.
Utility model content
The purpose of this utility model is that in view of the deficiency of the prior art, providing a kind of semicircle of abnormal workpieces
Hole bore hole clamping apparatus.The semicircle orifice bore hole clamping apparatus adjustment of the abnormal workpieces is convenient, maintenance is simple, efficient accurately bore hole
Device.
The technical solution of the utility model includes clamping substrate equipped with boring cutter receiving portion, is fixed at described clamp respectively
The positioning device of the opposite sides of the corresponding one side of substrate and corresponding two groups of workpiece pressuring clamping devices, are set to and clamp substrate
The positioning device of opposite side includes that a face wall surface corresponding to associated workpiece one, side stage terrace and side wall surface are flat respectively
The corresponding equal height cushion block in face, locating piece and positioning column are set to and clamp substrate with respect to the positioning device of the other side and include
Corresponding face wall surface and the corresponding corresponding equal height cushion block of side wall facial plane and positioning column, the folder with associated workpiece two respectively
The equal height cushion block for filling the positioning device of substrate opposite sides is mutually contour.
Positioned at clamping there are two the positioning device of substrate opposite sides its positioning column is respectively set, equal height cushion block point
There are three not setting.
The boring cutter receiving portion is a receiving hole, and the back end for clamping substrate of the receiving hole is provided with and corresponding lathe
The round concave station seam allowance of connection.
The utility model is relative to its advantageous effects of existing similar device: scroll chuck is eliminated, fixture is direct
It is locked on machine tool chief axis turntable, eliminates eccentric shake and improve the speed of mainshaft；By being reclined in side surface of workpiece with locating piece, mention
High clamping efficiency；Guarantee positioning spacing and level by the way that corresponding positioning column is arranged, only needs rotational angle after positioning column abrasion
Or replacement, convenient for disassembly and assembly, accurate positioning.Its design structure is reasonable, easy to operate, machining accuracy is high, improves production effect
Rate.
Detailed description of the invention
Fig. 1 is an embodiment of the present invention structural schematic diagram；Fig. 2 is Workpiece clamping schematic diagram；Fig. 3 is one (work of workpiece
Part two) structural schematic diagram.
Specific embodiment
To further appreciate that the technical solution of the utility model, now by embodiment combination attached drawing to the utility model make into
One step explanation.
As shown in Figs. 1-3.The semicircle orifice bore hole clamping apparatus of this abnormal workpieces clamps substrate 1 including one, is set to and clamps
Positioning device and two groups of workpiece pressuring clamping devices on outer (front) wall surface of substrate etc..It clamps and offers appearance in the middle part of substrate
Receive the boring cutter receiving hole 2 of boring cutter, backrest surface one end of boring cutter receiving hole is provided with round concave station seam allowance.
Its positioning device includes being respectively arranged at the docking with two halves workpiece (i.e. workpiece one and workpiece two) for clamping substrate
Line of symmetry 3 is two positioning device of left and right of the left and right opposite sides part of boundary.Its two halves workpiece includes one 8a of workpiece and workpiece
Two 8b, workpiece to be machined (fork truck support base) are made of one 8a of workpiece and two 8b of workpiece docking.A left side corresponding to one 8a of workpiece
Positioning device include with one 8a of workpiece to be located at a face wall surface inside (back side) corresponding and be distributed in the different parts of workpiece one
Three equal height cushion block 4a, locating piece 6 corresponding with the side stage terrace 10 of workpiece one and the side wall with the corresponding side of workpiece one
The corresponding two positioning columns 5a of facial plane 11.
Right positioning device corresponding to two 8b of workpiece includes corresponding with the wall surface positioned at the back side of workpiece two and is distributed in work
Three equal height cushion block 4b of the different parts of part two, and two positioning corresponding with the side wall facial plane 11 of the corresponding side of workpiece two
Column 5b.
The setting position of two positioning devices of left and right ensures that the semicircle end face 12 of workpiece one and workpiece two is mutually butted.It is clamped
The equal height cushion block of the positioning device of substrate opposite sides is mutually contour.
Two groups of workpiece pressuring clamping devices correspond respectively to workpiece one and workpiece two, every group of workpiece pressuring clamping device include respectively with phase
Corresponding three compactors of the equal height cushion block answered, compactor is by being connected to several stud 7a clamped on substrate, being connected to spiral shell
The pressing plate 7b of the wall surface for being located at positive (outside) of column and associated workpiece and the locking screw being connected on corresponding stud and pressing plate
Female 7c.
When clamping workpiece, first workpiece one is laid flat and is supported on the equal height cushion block of left positioning device, the side stage rank of workpiece one
Face paste keeps left the locating piece of positioning device, the positioning column of the left positioning device of side wall surface plane abutment of workpiece one, then with corresponding
One group of workpiece pressuring clamping device locks workpiece one；Workpiece two is symmetrically docked to the contour pad for lying in right positioning device with workpiece one again
On block, and the semicircle end face of workpiece two is made to recline the semicircle end face of workpiece one, the right positioning dress of the side wall surface plane abutment of workpiece two
The positioning column set locks workpiece two with another group of workpiece pressuring clamping device；Clamping workpiece is completed, Boring can be carried out.This reality
It only needs to be unclamped the pick-and-place that can complete workpiece with its novel workpiece pressuring clamping device, is not required to dismantle.
