Abstract
The invention discloses an internal rounding fixture which comprises a fixture body and a plurality of pressure blocks. The fixture body is disc-shaped and fixed onto a chunk, a positioning component for fixing to-be-machined workpieces is arranged on the outer end face of the fixture body and consists of a plurality of dowels arrayed according to shapes of the to-be-machined workpieces in the center of the fixture body, and the dowels are all positioned outside the to-be-machined workpieces. One end of each pressure block tightly presses the to-be-machined workpieces through adjusting bolts on the fixture body while the other end of each pressure block is fixed onto the fixture body through screws. Using the internal rounding fixture can conveniently fix non-cylindrical workpieces onto a grinding machine for machining, and the internal rounding fixture is simple in structure, easy to manufacture and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of frock clamp, relate in particular to the anchor clamps of using on a kind of internal and external grinding machine, belong to technical field of tooling clamps.
Background technology
When injection mould processing, some part need be processed inboard circle or outside circle, generally all be with the workpiece to be processed clamping on the chuck of grinding machine, process.But for some injection mold, its profile that many workpieces to be processed are arranged is not columniform, has plenty of cuboid, has plenty of six prismatic.For the processing of this type workpiece, if utilize the chuck clamping, processed workpiece just has very big error, nor locatees easily.Bring a lot of inconvenience to production, thus existing injection mold process for ease, all be designed to as far as possible columniform.But for some injection molds, wherein between the profile of many parts be to be designed to columniformly, this just brings a very big difficult problem to Mould Machining.
Summary of the invention
The present invention seeks to provide the interior rounding anchor clamps of a kind of convenient location, processing non-cylindrical work piece for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the present invention adopts is: rounding anchor clamps in a kind of comprise clamp body and briquetting; Said clamp body is a disc, and clamp body is fixed on the chuck; The outside end face of said clamp body is provided with the fixedly positioning component of workpiece to be processed; Said positioning component is a plurality of pins, and pin is arranged according to the shape that is positioned at the workpiece to be processed at clamp body center; Said pin all is positioned at the outside of workpiece to be processed; Said briquetting is a plurality of; One end of said briquetting compresses workpiece to be processed through the adjusting bolt that is positioned on the clamp body, and the other end of briquetting is fixed on the clamp body through screw.
Preferably, said positioning component is many groups, and all arranges according to the shape of different workpieces to be processed.
Preferably, said briquetting all is positioned at the outside at the angle on the workpiece to be processed.
Preferably, each outside, bar limit of said workpiece to be processed all is provided with two or more pins.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Rounding anchor clamps in the present invention program a kind of, utilize positioning component with workpiece to be processed be positioned at clamp body in the heart, and workpiece to be processed is fixed through briquetting; Again clamp body is fixed on the grinding machine through chuck, workpiece is processed, adopt these anchor clamps can be easily with non-cylindrical work piece; Be fixed on the grinding machine and process; And it is simple in structure, and is easy to manufacture, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of interior rounding anchor clamps of the present invention;
Accompanying drawing 2 is the front view of accompanying drawing 1;
Wherein: 1, clamp body; 2, pin; 3, workpiece to be processed; 4, briquetting; 5, regulate bolt; 6, screw.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
With processing square workpiece is example, and accompanying drawing 1,2 is a kind of interior rounding anchor clamps of the present invention, comprises clamp body 1 and briquetting 4; Said clamp body 1 is a disc, and clamp body 1 is fixed on the chuck; The outside end face of said clamp body 1 is provided with the fixedly pin 2 of workpiece to be processed 3; Said pin 2 is eight, and pins and 2 arrange according to the shape that is positioned at the workpiece to be processed 3 at clamp body 1 center; Said pin 2 all is positioned at the outside of workpiece to be processed 3, and each outside, bar limit of workpiece to be processed 3 all is provided with two pins 2; Said briquetting 4 is four, and briquetting 4 all is positioned at the outside at the angle on the workpiece to be processed 3; One end of said briquetting 4 compresses workpiece to be processed 3 through the adjusting bolt 5 that is positioned on the clamp body 1, and the other end of briquetting 4 is fixed on the clamp body 1 through screw 6.
During use, workpiece is positioned at the center of clamp body with pinning, and fixes workpiece, again clamp body is fixed on the grinding machine through chuck, process through briquetting.Can also many group positioning components be set according to the multiple different shape of workpiece to be processed on the clamp body.Utilize positioning component with workpiece to be processed be positioned at clamp body in the heart, and workpiece to be processed is fixed through briquetting, again clamp body is fixed on the grinding machine through chuck; Workpiece is processed; Adopt these anchor clamps be fixed on the grinding machine and process, and it is simple in structure easily with non-cylindrical work piece; Easy to manufacture, low cost of manufacture.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
