It crosses special fixture to reach accurate positioning, clamp the advantages that rapid, swift to operate, is easy to guarantee machining accuracy, shortens non-cutting time.
The part blank is casting, belongs to thin-walled parts, and wall thickness is only 2.5mm, though shape is simple, and it is in T shape, it is processed
Cheng Zhong will also guarantee symmetric relation of the hole location relative to axis of workpiece in addition to guarantee the wall thickness requirement after processing.Part pedestal
There are 4 6.1 holes Φ, is ± 0.12mm apart from outline edge and hole location tolerance.Initially when processing, clamped after scribing line using vice
It drills after playing WU punching, but since auricle wall ratio is relatively thin, when drilling is easy to cause deformation, and bored hole location deflection is caused to lead to wall
It is thick overproof；If pedestal is bonded with vice surface, vice can be hurt, and the part is to produce in enormous quantities, it is improved, it uses
Assembling clamp drilling, although assembling clamp can satisfy drawing requirement, the assembling clamp period is long, and each splicing structure is not
Together, it is difficult to ensure that the stability and processing efficiency of product, the serious manufacturing schedule for restricting part, become the bottleneck problem of production.
Summary of the invention
In view of the problems of the existing technology, the present invention proposes a kind of T shape thin-section casting pedestal boring grab.
The technical solution of the present invention is as follows:
A kind of T shape thin-section casting pedestal boring grab, including bushing plate 1, locating piece 2, positioning pin 3, high stabilizer blade 4, hexagonal
Nut 5, mobile pressing plate 6 and drill bushing 7；
The bushing plate 1 is tabular, and side is equipped with handle, is convenient for turning operation；1 four edges of bushing plate are equipped with logical
Hole, the high stabilizer blade 4 are inserted into the through-hole, are fixed on bushing plate 1 by hex nut 5；1 interposition of bushing plate installs
There is hole, part is placed on bushing plate 1, and hole location to be processed is corresponding with the hole in 1 middle position of bushing plate, 1 middle position of bushing plate
Drill bushing 7 is fixedly mounted in hole, the drilling for part hole location is processed；
The mobile pressing plate 6 is bolted on bushing plate 1, for part pedestal to be pressed on bushing plate 1；
The locating piece 2 is bolted on bushing plate 1, and locating piece 2 is equipped with the extension end of strip, for being adjacent to part caudal peduncle
Side positioned；
The positioning pin 3 is set on bushing plate 1, and totally two, the side for being adjacent to part pedestal is positioned.
Fixture application method is as follows:
Locating piece 2, high stabilizer blade 4 are fixed on bushing plate 1, according to location dimension on bushing plate 1 by the first step with bolt
Positioning pin 3, and 3 drill bushings 7 are installed；
Second step upward by high stabilizer blade 4 unclamps the mobile pressing plate 6 in two sides；
Part is attached on bushing plate 1 by third step, and caudal peduncle side is bonded with locating piece 2, positioning pin 3, with 0.05mm clearance gauge
Test part and fixture contact surface, if compressing mobile pressing plate 6 into not going；
Part and fixture after installation is stablized, are overturn 180 °, start lathe, process part by the 4th step.
Beneficial effects of the present invention:
1. using very convenient, and fixture is exquisite；2. improving processing quality, parts product quality is improved；3. improving zero
Part processing efficiency；4, the fixture versatility is stronger, can be used for that base dimensions requirement is identical, the different various parts of caudal peduncle length,
Save production cost.

Specific embodiment
Below in conjunction with attached drawing and technical solution, specific embodiments of the present invention are further illustrated.
As shown in Figure 1, a kind of T shape thin-section casting pedestal boring grab, including bushing plate 1, locating piece 2, positioning pin 3, height
Stabilizer blade 4, hex nut 5, mobile pressing plate 6 and drill bushing 7；
The bushing plate 1 is tabular, and side is equipped with handle, is convenient for turning operation；1 four edges of bushing plate are equipped with logical
Hole, the high stabilizer blade 4 are inserted into the through-hole, are fixed on bushing plate 1 by hex nut 5；1 interposition of bushing plate installs
There is hole, part is placed on bushing plate 1, and hole location to be processed is corresponding with the hole in 1 middle position of bushing plate, 1 middle position of bushing plate
Drill bushing 7 is fixedly mounted in hole, the drilling for part hole location is processed；
The mobile pressing plate 6 is bolted on bushing plate 1, for part pedestal to be pressed on bushing plate 1；
The locating piece 2 is bolted on bushing plate 1, and locating piece 2 is equipped with the extension end of strip, for being adjacent to part caudal peduncle
Side positioned；
The positioning pin 3 is set on bushing plate 1, and totally two, the side for being adjacent to part pedestal is positioned.
When processing the part, after first carrying out milling to caudal peduncle both sides of the face, since part pedestal shape is that casting is non-processing
Surface after polishing its pedestal positioning surface, is then positioned with the plane polished and caudal peduncle side, drilling, it is contemplated that zero
The hole location mounting hole that part is processed, and wall thickness is thin, solid capacity is small, therefore drill bushing is designed to fixed drill bushing；Since part is in " T
Shape ", wall ratio is relatively thin, and when drilling is easily deformed, and causes hole location overproof, therefore in order to improve the stability of parts fixation, by ear mount
Bottom surface is bonded with bushing plate, while adding high foot support, keeps chip removal smooth, realizes that workpiece loading and unloading is convenient, fast.
Fixture application method is as follows:
Locating piece 2, high stabilizer blade 4 are fixed on bushing plate 1, according to location dimension on bushing plate 1 by the first step with bolt
Positioning pin 3, and 3 drill bushings 7 are installed；
Second step upward by high stabilizer blade 4 unclamps the mobile pressing plate 6 in two sides；
Part is attached on bushing plate 1 by third step, and caudal peduncle side is bonded with locating piece 2, positioning pin 3, with 0.05mm clearance gauge
Test part and fixture contact surface, if compressing mobile pressing plate 6 into not going；
Part and fixture after installation is stablized, are overturn 180 °, start lathe, process part by the 4th step.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
