Description
Technical field
The utility model relates to a kind of replacement positioning devices, and in particular to a kind of replacement positioning for knockout special fixture
Device.
Background technique
Aluminium alloy castings need to carry out peeling after casting and forming, and the sand removing method of aluminium alloy casting machine has two at present
Kind: one is artificial knockouts, i.e., in general foundry, by manually knockout on the spot, this is mainly used for jobbing work, exists
The low disadvantage of large labor intensity, production efficiency.Another kind is mechanical knockout, generallys use mechanical equipment knockout, it is cast aluminium
Alloy components are placed on viberating knock-out machie makes sand fall by vibration, and with popularizing for mechanization, mechanical knockout is gradually taken
For traditional artificial knockout mode.But need to be equipped with different fixtures according to different production requirements in mechanical knockout, this
It requires often to replace different types of fixture, quick-replaceable and positioning in order to facilitate fixture, be badly in need of a kind of special for knockout
With the replacement positioning device of fixture.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of replacements for knockout special fixture to position dress
It sets, quick-replaceable and positioning of the jig plate on equipment bay may be implemented.
To realize above-mentioned technical proposal, the utility model provides a kind of replacement positioning dress for knockout special fixture
It sets, comprising: hammering head, jig plate and equipment bay, the upper left corner and the lower right corner of the equipment bay upper surface are respectively arranged with
First positioning pin and the second positioning pin, the upper left corner and the lower right corner of jig plate are respectively arranged with to be positioned with the first positioning pin and second
Sell corresponding first positioning hole and second location hole, the jig plate by first positioning hole and second location hole respectively with set
The first positioning pin and the second positioning pin on standby bottom plate are correspondingly connected with, and knockout fixture is mounted on the center of jig plate, and hammering head is only
Erect the side for being placed in jig plate or equipment bay.
In the above-mentioned technical solutions, when replacing fixture, only hammering head need to be used to tap equipment bay from bottom to top, will pressed from both sides
After tool plate shakes loose, so that it may take out jig plate from equipment bay；After replacing different clamp types, it need to will only be set on jig plate
The first positioning hole and second location hole set respectively with the first positioning pin on equipment bay and after the second positioning pin is aligned, then
Jig plate is tapped using hammering head and enters equipment bay, and jig plate is close to equipment bay, prevents knockout process
Middle jig plate loosens.In this way, which quick positioning and replacement of the jig plate on equipment bay may be implemented.
Preferably, first positioning pin and the second positioning pin are designed to cylindric, and the first positioning pin and second is determined
The size of position pin is identical, is both designed as outer diameter 5mm, high 15mm, and the first positioning hole and second location hole are disposed as circular hole,
The internal diameter of the circular hole is 5.2mm.A difference is needed between the internal diameter of location hole and the outer diameter of positioning pin, and this difference is not
Can be too small, it otherwise cannot achieve the quick socket between positioning pin and location hole, while the internal diameter of location hole and positioning pin is outer
Difference between diameter also should not be too large, and otherwise will lead to jig plate during knockout and is easy to loosen, knockout effect is caused to be deteriorated.
It is demonstrated experimentally that positioning pin not only may be implemented and determine when the difference between the internal diameter of location hole and the outer diameter of positioning pin is 0.2mm
Quick socket between the hole of position, and in the operation of actual knockout, jig plate is not easy to loosen, and knockout effect is good.
Preferably, the outer surface of first positioning pin and the second positioning pin is the smooth surface by polishing treatment, institute
The inner surface for stating first positioning hole and second location hole is smooth surface by polishing treatment, when facilitating docking, jig plate with
Quick positioning socket between equipment bay.
Preferably, the jig plate and equipment bay are ABS material or alloy material, and the hammering head is cast iron material
Matter.
A kind of beneficial effect of replacement positioning device for knockout special fixture provided by the utility model is: this use
It is simple in the replacement positioning device structure of knockout special fixture, design rationally, it is easy to use, when replacing fixture, only need using
Hammering head taps equipment bay from bottom to top, after jig plate is shaken loose, so that it may take out jig plate from equipment bay；Replacement
After different clamp types, only need to by the first positioning hole being arranged on jig plate and second location hole respectively with the on equipment bay
After one positioning pin and the alignment of the second positioning pin, reuses hammering head and tap jig plate into equipment bay, and to press from both sides
Tool plate is close to equipment bay, prevents jig plate during knockout from loosening, in this way, which jig plate may be implemented in equipment bay
On it is quick positioning and replacement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, hammering head；2, jig plate；21, knockout fixture；22, first positioning hole；23, second location hole；3, equipment
Bottom plate；31, the first positioning pin；32, the second positioning pin.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Ordinary people in the field's every other embodiment obtained without making creative work, belongs to
The protection scope of the utility model.
A kind of embodiment: replacement positioning device for knockout special fixture.
