Description
Technical field
The present invention relates to a kind of fork head type fixture.
Background technology
Casting tool has following several installation positioning methods：
Shoulder is fixed：The fixed form that through hole cage plate uses.Bottom is carried to the insert of boss, after being pressed into cage plate, passed through
Screw compresses movable mold support plate or top clamping plate with cage plate.If insert is oversized, enhancing spiral shell can also be set in centre
Nail.The band boss of generally rounded insert one week, non-circular insert only need setting unit boss, and big insert two sides band boss is small
Insert one-side band boss.When for circle and having direction requirement, also need to set up defences and ship and resell on another market to prevent from misplacing.This fixation side
The die casting that formula applies in general to die cavity relatively depth or cavity or narrow insert can not use screw to fasten.
Screw fastens：The mould shallower to cylinder insert or die cavity is fastened using screw, to the monotype of non-cylindrical insert
Chamber die casting can also use screw to fasten, and be now, between insert and cage plate and cage plate and seat board that screw is fixed.It is and right
In deep-small hole, for the ease of processing, insert is frequently with more than two pieces as depicted of insert composed structure.
Shoulder and straight pin coordinate fastening：When insert is thiner and quantity is more, processing boss difficulty is larger, now only
Two outside inserts are processed into boss, are connected in series all small inserts with straight pin, then all inserts are pressed into cage plate together.
However, above-mentioned Set and Positioning whether clamping in place, that is, casting roughing standard face to tool locating reference plane whether clamping in place,
It is main still by manually being detected using clearance gauge at present, the frock of casting is judged with rough clearance gauge data and working experience
Situation in place.This mode limits casting there is the problems such as detection is inconvenient, precision is low, limitation is larger, automaticity is poor
The production efficiency of product.
No. 201110230286.9 Chinese invention patents of 2 months 2012 Application No. disclosed in 1 day, it is invented
Entitled " casting tool detection clamp and its detection method ", it includes bottom plate, corner oil cylinder and benchmark boss, benchmark boss by
Benchmark boss with alignment pin and the interior benchmark boss for setting through hole are formed；Inside set and pass through pipeline below the benchmark boss of through hole
Equipped with pressure sensor, the pressure sensor connects with microcomputer controller.Above-mentioned patent application, passed by monitoring each pressure
Whether the change of pressure in sensor, can monitor whether corresponding benchmark boss has gap, namely be installed in place.
The installation of above-mentioned casting tool whether detection fixture in place and frock, provided just for operator and user really
Profit, however it remains following deficiency：Find that casting tool installation is not in place 1. working as, namely pressure sensor is detected
When pressure is less than setting value, microcomputer controller can only carry out early warning, it is impossible to and it is adjusted, still needs to after manually casting has been removed,
Adjustment is reapposed and positioned, is then detected again.It is low that Adjusting accuracy is positioned manually, is typically required to multi-pass operation, adjusts
Time is grown, and efficiency is low.2. in process, loosened when clamping occurs in corner oil cylinder, pressure sensor detects pressure less than setting
During definite value, microcomputer controller can only also carry out early warning, when scene does not have operating personnel, equipment will autostop, when existing
When head's time is unattended or repairs, the equipment also will always be in dead state, and this imitates the processing for having a strong impact on production
Rate.3. directly casting is removed and has put down progress again during out-of-flatness inside benchmark boss top or casting tool bottom positioning chamber
The method of positioning, it is difficult to be installed in place casting tool, generally require and rotate casting tool, exchange casting tool inner chamber and base
The pairing order of quasi- boss, can carry out accurately installation positioning.So, the labor intensity of operating personnel, production effect will be increased
Rate will also decrease.
The content of the invention
The above mentioned problem that the present invention needs to solve is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of fork head type folder
Tool.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of fork head type fixture, including bottom plate, a pair of substrates, a pair of clamping plates and a jaw；A pair of substrates are relatively fixed to bottom
On plate, a pair of clamping plates are relative located at the inner side of a pair of substrates, and bottom plate is provided with chute, the trend of chute and the company of two clamping plates
Line is consistent, and the lower slide of clamping plate is connected in chute, and back-moving spring is provided between the substrate and clamping plate of homonymy, and jaw has two
Yoke, the wedge-shaped in cross-section of yoke, and the small rear end in front end is big, jaw is fixed on bottom plate by extensible member, and two yokes
Front end correspond to space between the substrate of both sides and clamping plate respectively.
Clamping plate towards substrate side be convex arc surface.
The opposite one side of clamping plate is concaved circular cambered surface.
Extensible member is hydraulic cylinder or pneumatic cylinder.
The front end of yoke carries out chamfer machining.
Compared with prior art, the beneficial effects of the invention are as follows：The front end of two yokes correspond to respectively the substrates of both sides with
Space between clamping plate, when extensible member extends, two yokes insert the space between substrate and clamping plate respectively, because yoke is in
Wedge shape, so two clamping plates are pressed together, so as to step up workpiece to be processed, when when extensible member shortens, yoke is taken out
From in the presence of back-moving spring, clamping plate is pulled, and so as to unclamp workpiece, the fixture is very easy to use, and structure
Simply.
