The quick screw rod pressing device is a quick screw rod pressing device used for the mass part processing of milling and drilling in the machinery manufacture, and has the advantages that the structural design is reasonable, the positioning accuracy is high, the manufacturing cost is low, the enterprises can be helped in solving the problem of slow work piece clamping and replacing process, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of anchor clamps of machining, especially relates to a kind ofly making datum level at the bottom of having one, but middle with holes or the additional process hole, the quick screw rod hold down gag of parts processing in batches.
Background technology
In the machining, workpiece generally all will unclamp taking-up to clamp nut when installing and change, put into workpiece after, screw in whole nut again, its efficient is quite low.Product orientation and anchor clamps technology always are processing enterprise main attack objects, and its objective is should the precision height, and speed is fast again, also wants cost low, so the mode of anchor clamps is also varied on the market.
As the patent No. is 200510072002.2 1 kinds of precision location clamps, be the usefulness of clamping location workpiece, one base and Flexible element and a toggle unit are arranged, there is a first end that articulates mutually its toggle unit, and one the another part that articulates with holder respectively form, if its clamping work rely on angle lever individual operating position finish, the similar bench vice of this structure, can make things convenient for the workpiece of clamping horizontal positioned, and to a bottom surface or interstitial hole being the very difficult location of product processing of benchmark, clamping speed also can not improve, and its structure is more than the utility model structure also complexity.
And for example the patent No. is 200420090933.6 1 kinds of positioning fixtures, base is provided with square shaped teeth and four boss, base is connected by connecting rod with grip block, utilize the base square teeth to carry out the location of 4 * 90 degree, it is convenient available at the work step of processing orthogonal of same part or different directions, and when its main shortcoming was the batch machining workpiece, the loading, unloading workpiece was slow, be not suitable for the product processing of the same work step of part of the same race in enormous quantities, also differ widely with this screw rod hold down gag structure.
And for example the patent No. is 02261777.9 a kind of quick positioning fixture, one end is fixed with the fixedly guide rod of holder, the live splint main body that the location mobile device is arranged on the guide rod, clamping workpiece is not to be one of them location benchmark with the center of pilot line, its clamping force is also smaller, especially to middle position have machining hole workpiece and will with interstitial hole for one of them the location benchmark product inoperative, horizontal direction more can't be located.It can load and unload fast, but can not locate fast.And machine tooling is stressed more improper.
Summary of the invention
The purpose of this utility model is to solve to have a baseplane to make datum level, the middle part is with holes or slow, the inefficient problem of loading and unloading of the similar machine components processing of fabrication hole arranged, provide a kind of reasonable in design, simple and convenient, the quick screw rod hold down gag of low cost of manufacture.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model is made up of location axle bed and movable compacting part.Base has a baseplane, locating piece, alignment pin are admittedly above base, apotting spindle is fixed on the top of locating piece, screw rod is fixed on the apotting spindle, and it is vertical with base end face, endoporus is sleeved on the screw rod greater than the open washer of maximum sized quick change briquetting of clamp nut profile and band U-shaped opening, is close to quick change briquetting plane below the open washer, is provided with clamp nut above.
Workpiece passes through apotting spindle, locating piece and alignment pin, the six-freedom degree of restriction part to be processed, finish the reliable location of work piece, put into the quick change briquetting and insert open washer along screw rod then,, finish clamping by clamp nut being screwed in the screw rod workpiece pressing, whole pedestal is fixed on the lathe, can carry out the processing such as milling, drilling of part.
Parts of the present utility model are few, and are simple in structure, and processing is got up easily, low cost of manufacture.
As preferably, described base, apotting spindle, locating piece, alignment pin and screw rod are assembled into one, and these parts can be converted.Apotting spindle is vertical with base with screw rod assembling back.Locating piece adopts soket head cap screw to be connected with base, wherein the size of locating piece can be suitable by processed element size, alignment pin and base cooperate separately, be processed into flat with convenient location, several of multi-processings are standby, and the location hole of alignment pin also can be set quantity 3-5 by the size of processing work.
As preferably, described alignment pin is located at the last plane of base, and as the location of processing work, it cooperates and adopts interference fits, and workpiece is not come off when cutwork easily, and it is also easy to change.Screw rod and apotting spindle fuse, and when cooperatively interacting, its six-freedom degree all will retrain, and for making processing more convenient, also can be processed into a part to screw rod and apotting spindle, and its axiality relatively easily guarantees.When apotting spindle, locating piece and screw rod and base were formed one, the free degree was each other retrained fully, becomes one.
As preferably, described quick change briquetting has bigger endoporus, and greater than the maximum appearance and size 2mm of clamp nut, making is not having under the situation of open washer, is easy to a quick change briquetting and takes out along screw rod from the nut direction at least.During clamping workpiece, directly contact with workpiece to be machined below the quick change briquetting.
As preferably, described open washer astragal U-lag, its U type slot length are half of its appearance and size, and promptly U-shaped center of arc's point is in the center of its length and width, and in the time of so in working order, the clamp nut applied pressure is at the middle part of open washer.The full-size of open washer should be suitable with the quick change briquetting, suitably dwindles 5-10mm.
As preferably, described clamp nut can adopt plain nut or T type nut, and with the screw rod processing that matches, screw flight length is 2-3 nut thickness.When workpiece, quick change briquetting, when open washer installs, just can make the workpiece location and clamp as long as tighten clamp nut.
As preferably, four installing holes on the described base mainly are that the T-slot with the lathe table top fixes, and when processing parts, its level reference is to determine that by the baseplane of base the base above and below depth of parallelism has certain requirement.Four installing holes of base are the U-lag hole on the symmetric position, on lathe platforms such as milling, drilling, can Yangjing platform T type groove direction, and chosen position is installed arbitrarily.
Therefore, the utlity model has reasonable in design, the positioning accuracy height, low cost of manufacture can help enterprise to solve quick-clamping and changes the difficult problem of workpiece, characteristics such as enhance productivity.
