Abstract
The utility model discloses a base plate of a clamp, which comprises a plurality of positioning holes (1) and a peripheral surface (2), wherein the peripheral surface (2) surrounds the positioning holes (1), and a recessed area (3) recessing inwards is arranged at one side of the peripheral surface (2); and the recessed area (3) comprises a first circular arc (4) and a second circular arc (5) which are connected with each other in sequence, wherein the first circular arc (4) protrudes towards the positioning holes (1), and the second circular arc (5) protrudes towards a bottom edge of the base plate of the clamp. The base plate of the clamp has the advantages of flexible structure and good positioning effect, and the defects in the prior art are overcome.
Description
Technical field
The utility model relates to a kind of fixture substrate.
Background technology
High speed development along with computer technology, the change of essence has taken place in traditional manufacturing industry, utilize Digit Control Machine Tool processing, the quality conformance of its product processing is good, the efficient of machining accuracy all exceeds much than machine tool, especially add man-hour at the plant product of compoundization processing and high-precision requirement of irregular, the complicated curve of profile or curved surface, multiplex (MUX), its advantage is that traditional machine tool is incomparable.Anchor clamps are important component parts of numerical control machining center, its effect is that workpiece is fixed on the accurate position of lathe, finish various processing to workpiece, should accurate positioning reliable clamping again, obviously the quality of its structure has fundamental influence to machining accuracy, working (machining) efficiency. it has the processing range that guarantees machining accuracy, boost productivity, reduce cost, enlarge lathe, alleviate advantage such as working strength of workers.General anchor clamps are used for especially with the in place so that processing of pinpoint piece-holder, and anchor clamps have usually and are used to install or the tray for work pieces of each workpiece of clamping.In producing continuously, the workpiece to be processed blank directly inserts in the lathe usually.In small-sized continuous production, be clamped on the pallet by the artificially or replacing automatically in lathe for processing work, and in medium-sized continuous production, piece-holder then more complicated in place or pallet is relatively more expensive.The corresponding fixture substrate of product of prior art lower clamp, production cost height, mechanism lack flexibility.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model be to provide a kind of mechanism flexibly, the fixture substrate of good positioning effect.
For reaching above purpose, the utility model provides a kind of fixture substrate, comprises a plurality of locating holes and around the outer peripheral face of described locating hole, described outer peripheral face one side is formed with the depressed area that caves inward.
Further improvement of the utility model is that the quantity of described locating hole is 3.
Further improvement of the utility model is, the circle center line connecting besieged city right-angle triangle of described locating hole.
Further improvement of the utility model is that the diameter of described locating hole is 2cm.
Further improvement of the utility model is that wherein three limits of described outer peripheral face and the angle on adjacent both sides are 70 °～110 °.
Further improvement of the utility model is that described depressed area comprises two first circular arcs that are connected successively and second circular arc, and described first circular arc is outstanding towards the locating hole direction, and described second circular arc is outstanding towards described fixture substrate base.
Further improvement of the utility model is that the radian of described first circular arc is greater than the radian of described second circular arc, and the radius of described first circular arc is less than the radius of described second circular arc
The beneficial effects of the utility model are: owing to adopted above technical scheme, make that a plurality of products can shared anchor clamps, reduced anchor clamps and manufactured a finished product that reduced production cost, product construction is flexible.
Description of drawings
Accompanying drawing 1 is the front view of fixture substrate in the present embodiment.
Wherein
1, locating hole; 2, outer peripheral face; 3, depressed area; 4, first circular arc; 5, second circular arc.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1, a kind of fixture substrate comprises locating hole 1 and around the outer peripheral face 2 of locating hole 1, outer peripheral face 2 one sides are formed with the depressed area 3 that caves inward.
The quantity of locating hole 1 is 3 in the present embodiment, the circle center line connecting besieged city right-angle triangle of locating hole 1, and the diameter of locating hole 1 is 2cm.Locating hole 1 can have three kinds of occupation modes, and first kind in use, and fixture substrate is covered on the tool to be processed, uses three positioning fixtures and locating hole 1 to cooperate, and positioning fixture passes locating hole 1 and is fixed towards processed products; Second kind for when need fixing a point to add man-hour towards processed products, and drill bit passes locating hole 1, carries out drilling operation towards processed products, and the diameter of locating hole 1 has determined the diameter in the hole of the product that processes; The third needs product processed outward flange volume ratio bigger for working as, do not had in the machine table outside can mounting and positioning device the space, and inside is when existing part hollow, at this moment just fixture substrate is placed on product inside, on locating hole, draw positioner, the other end of positioner compresses processed product, positions from the inside of product.
Depressed area 3 comprises that two first circular arcs 4 that are connected successively and second circular arc, 5, the first circular arcs 4 are outstanding towards locating hole 1 direction, and second circular arc 5 is outstanding towards the fixture substrate base.The radian of first circular arc 4 is greater than the radian of second circular arc 5, and the radius of first circular arc 4 is less than the radius of second circular arc 5.First circular arc 4 is connected with second circular arc, 5 ends and forms the camber pattern of a phase sunken inside.The radian of first circular arc 4 is π in the present embodiment, and the radian of second circular arc 5 is 2 π/3.Also there are two kinds of occupation modes depressed area 3, and first kind of occupation mode is the insertion that makes things convenient for backstay, and 3 radian moves backstay along the depressed area in process, can treat the outer surface that processing object processes identical radian measure; Second kind of occupation mode makes positioning element slip into first circular arc 4 for use second circular arc 5 before processing, and 4 pairs of positioning elements of first circular arc carry out stuckly in process, make processed product obtain the location.
By above embodiment as can be seen, the utility model is that a kind of mechanism is flexible, the fixture substrate of good positioning effect.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this, all equivalences of doing according to the utility model spirit essence change or modification all is encompassed in the protection domain of the present utility model.
