Abstract

The utility model discloses a fast-clamping multi-pressure head clamp. The clamp comprises a clamp base, a support block for bearing workpieces to be processed is arranged on the clamp base, and a positioning mechanism for positioning the workpieces and a pressing block array for locking the workpieces are further arranged on the base. Compared with the prior art, the utility model has the benefits that firstly, the clamp is modified based on the prior art to achieve simple and reasonable structure, good rigidity and long service life; secondly, the operation is convenient and fast and can be automatically controlled by numerical control equipment; and thirdly, strong stability and small processing tolerance ensure that bad conditions of shock marks in processing, wrinkles and the like are avoided.

Description

But the multiple pressure fixture head of quick-clamping

Technical field

The utility model relates to a kind of anchor clamps, belongs to accurate CNC processed clip clamping apparatus technical field, but refers in particular to a kind of multiple pressure fixture head of quick-clamping.

Background technology

As shown in Figure 1, the product that the utility model is used is a main bearing seat, need carry out Precision Machining to 10 small end faces, side, each bolt via hole and the bottom surface thereof of main bearing seat, because the main bearing seat configuration design has two locating holes, first operation can process wide of 10 small end faces, side, bolt via hole and thrust according to this locating hole, and second operation is location, processing bolt via bottom end face and side according to 2 bolt via holes that finish ream out in first operation then.

At this product, the operation process is: first operation adopts the conical locating hole fixed product of product design, process 10 small end faces, side, bolt via hole and and wide of thrust; Second operation adopts the alignment pin of rhombus and round pin to locate two holes that first operation processes, in the centre position of product briquetting is set and compresses product, the 3rd operation and the 4th operation adopt special plane to come two Φ 149 round sides of heavy boring center semicircle orifice and processing intermediate journal.And in whole process, because product has bigger difference than all the other both directions on length direction, therefore, in order to adapt to the clamping requirement of this product, the applicant has carried out necessary improvement to prior art.

The utility model content

The purpose of this utility model is to overcome shortcoming of the prior art with not enough, but a kind of multiple pressure fixture head of simple and reasonable, convenient to operation, practical and reliable quick-clamping is provided.

To achieve these goals, the utility model is realized by following technical scheme:

But a kind of multiple pressure fixture head of quick-clamping includes clamp base, and clamp base is provided with and is used for the rest pad of support for processing work; Further, described clamp base is provided with the briquetting array that is used to locate the detent mechanism of workpiece and is used to lock workpiece.

Further, described briquetting array includes some briquettings to utilizing hydraulic control to open and close, and every pair of briquetting is arranged in the workpiece bilateral symmetry.

Further, described clamp base is provided with oil-collecting plate.

Further, described briquetting array adopts automation control system.

Further, described detent mechanism includes and uses coarse positioning parts and the fine positioning parts that cooperate.

Further, described coarse positioning parts include and are arranged on the clamp base and contact the thick limit stick that cooperates with workpiece inside groove contact, be arranged on the clamp base and contact the thick limited block that cooperates with the distolateral contact of workpiece and be arranged on the clamp base and contact the elastic bead seat of cooperation with workpiece bottom contact.

Further, described fine positioning parts include and are arranged on the clamp base and the profile locating piece and the location round pin that cooperate with workpiece bottom clamping.

The utility model compared with prior art, its beneficial effect is:

1, on the prior art basis, improve, simple and reasonable, good rigidly, long service life;

2, convenient to operation, can adopt numerical control device automation control;

3, stability is strong, and machining tolerance is little, can effectively avoid defective modes such as processing shake line, wrinkle.

In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
