Abstract
An anti-rotation positioning clamp comprises a base (1), wherein a positioning plate (2) is fixed on the base (1) and a positioning groove (3) is disposed in the positioning plate (2); and is characterized in that a threaded hole (3) is disposed on one side of the positioning plate (2) on the base (1), a long screw rod (4) is locked and threaded inside the threaded hole (3), a spring (5) is disposed on the long screw rod (4) in a sleeved manner, the top end of the spring (5) is pressed against a pressing plate (6), a bar groove hole (601) is disposed in the pressing plate (6) and the long screw rod (4) passes through the bar groove hole (601). In the utility model, the multiple threaded holes are disposed in the positioning plate for installation of the pressing plate in order to limit freedom degree of a part to be processed and reduce possibility in rotation. Meanwhile, the whole device is simple in structure, convenient in manufacturing, convenient in installation and cheap in cost.
Description
Technical field
The utility model belongs to machining auxiliary equipment technical field, specifically just relates to a kind of anti-rotation positioning fixture, prevents that for round piece processing workpiece rotation from affecting machining accuracy.
Background technology
Fixture is to be used for fixing processing object in machine-building process, makes it to occupy correct position, with the device of accepting construction or detecting, claims again jig.In a broad sense, any operation in technical process, is used for installing rapidly, easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe when processing work, for make the surface of workpiece can reach the size, geometry of drawing regulation and with the technical requirement such as other surperficial relative-position errors, before processing, workpiece must be installed to location, clip clamping.Fixture is conventionally by determining that setting element, the clamping device of workpiece tram in fixture, the relative position of determining cutter and workpiece or the tool setting induction element of guiding tool orientation, processing indexing mechanism, Connection Element and the clamp body etc. that make workpiece can complete several stations in once mounting form.
Fixture kind can be divided into by handling characteristics: 1. universal fixture: as machine vice, chuck, sucker, dividing head and rotary table etc., there is very large versatility, can adapt to preferably the conversion of manufacturing procedure and processing object, its structure is shaped, the seriation of size, specification, wherein great majority have become a kind of standard accessory of lathe.2. specificity fixture: for the clamping of certain product parts on certain procedure needs specialized designs manufacture, service object is single-minded, and specific aim is very strong, generally by product manufactory designed, designed.Conventional have turning attachment, fraise jig, drill jig (guiding cutter hole or the jig of the use that reams on workpiece), boring template (guiding the boring cutter bar jig that bore hole is used on workpiece) and a pallet (for the mobile clamping on transfer line of modular machine, automatic production line of modular machine).3. flexible jig: the special fixture that can change or adjust element.4. built-up jig.The fixture being made up of the standardized component of difformity, specification and purposes, is applicable to single-piece, small serial production and temporary duty that trial production of new products and product are often changed.
In general, fixture can be used for clamping the product of the needs processing of various shapes, circular processed product is also to locate to realize clamping object by fixture conventionally, but the free degree of circular product is owing to being that infinite causing easily rotates in circular product process engineering, especially in the time that circular product end face is carried out to cylindrical plane machining, due to the moment of torsion easily being rotated in circular product process, cause circular product to rotate, impact to processing.
Utility model content
The purpose of this utility model is to add for existing circular product the technological deficiency easily rotating man-hour, and a kind of anti-rotation positioning fixture is provided, and can realize location fast for the round piece with fabrication hole, prevents that it from rotating in process.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of anti-rotation positioning fixture, it comprises base, and location-plate is fixedly housed on base, and described location-plate is provided with locating slot, it is characterized in that: a side that is positioned at location-plate on described base has been attacked screwed hole, in screwed hole, screw fastening has long bolt, and on long bolt, cover has spring, and pressing plate is withstood in spring upper end, on pressing plate, have rectangular slotted eye, long bolt is through rectangular slotted eye.
Described location-plate is provided with locating post.
Described locating slot is circular.
On the base of described location-plate surrounding, attack screwed hole.
Beneficial effect
The utility model utilization has mode that multiple screwed holes install pressing plates the free degree to be processed is limited on location-plate, has reduced the possibility of its rotation, and meanwhile, whole apparatus structure is simple, easily manufactured, and convenient low cost is installed.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is front views of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in attached Fig. 1 and 2, a kind of anti-rotation positioning fixture, it comprises base 1, and location-plate 2 is fixedly housed on base 1, and described location-plate 2 is provided with locating slot 3, it is characterized in that: a side that is positioned at location-plate 2 on described base 1 has been attacked screwed hole 301,301 li of screw fastenings of screwed hole have long bolt 4, and on long bolt 4, cover has spring 5, and pressing plate 6 is withstood in spring 5 upper ends, on pressing plate 6, have rectangular slotted eye 601, long bolt 4 is through rectangular slotted eye 601.
Described location-plate 2 is provided with locating post 201.
Described locating slot 3 is circular.
On the base of described location-plate 2 surroundings, attack screwed hole 301.
The utility model utilization has mode that multiple screwed holes install pressing plates the free degree to be processed is limited on location-plate, has reduced the possibility of its rotation, and meanwhile, whole apparatus structure is simple, easily manufactured, and convenient low cost is installed.
