Abstract

The utility model provides a milling clamp which comprises a base (1), a gland (2) and a locking nut (3) which are correspondingly matched with the base (1), wherein a group of workpiece clamping jaws (4) are uniformly distributed on the gland (2). The utility model has simple structure and convenient use, can realize quick processing, solves the technical problems of elastic deformation, concentricity, various sizes which are difficult to ensure and the like of part clamping, avoids the bad conditions of scrapping and the like of parts, and greatly improves the production efficiency and quality.

Description

Milling fixture

The technical field is as follows:

the utility model relates to the field of machining, in particular to a milling clamp.

Background art:

the annular blank is adopted to process a plurality of parts, the machining mode is common in mechanical processing, and the problem of difficulty in clamping is a troublesome problem in the processing process. The milling machine normally uses the clamp plate to compress tightly the part, when milling cutter got the singleton, made elastic deformation, asymmetry appear in the part very easily, lead to inside and outside circle size decentraction, thereby the increase of geometric error, each precision of size can't be guaranteed, produces the part easily and scrapps, extravagant company material cost and processing cost.

The utility model has the following contents:

the utility model provides a milling clamp for overcoming the defects in the prior art.

The application provides the following technical scheme:

the utility model provides a milling fixture, it includes the base, corresponds complex gland and lock nut at the base, its characterized in that: the base is provided with a guide post correspondingly matched with the gland, the guide post is provided with a thread section correspondingly matched with the nut, the base is provided with link steps, the gland is uniformly provided with a group of workpiece clamping jaws, and each workpiece clamping jaw is provided with a notch correspondingly distributed with the link steps.

On the basis of the technical scheme, the following further technical scheme can be provided:

the base be round platform column structure, the guide post distribute at the base top and with base coaxial distribution.

The gland is circular, and the workpiece clamping jaws are uniformly distributed on the outer circular surface of the gland in a radial shape.

The middle parts of the notches are positioned at the bottom surfaces of the clamping jaws of the workpiece, and the middle points of the notches are on the same circumference.

Utility model advantage:

the utility model has simple structure and convenient use, can realize quick processing, solves the technical problems of elastic deformation, concentricity, various sizes which are difficult to ensure and the like of part clamping, avoids the bad conditions of scrapping and the like of parts, and greatly improves the production efficiency and quality.

Description of the drawings:

FIG. 1 is a schematic view of the structure of the present invention in operation;

FIG. 2 is a schematic view of the gland of FIG. 1;

fig. 3 is a partial schematic view of the present invention after completion of its work.

The specific implementation mode is as follows:

as shown in fig. 1-3, a milling fixture comprises a base 1 with a circular truncated cone-shaped structure, wherein a link step 1a is arranged at the upper part of the base 1, and a guide column 5 is further connected to the upper surface of the base 1 at the inner side of the link step 1 a. The upper and middle surfaces of the guide post 5 are in a stud structure with a thread section a, and the lower surface is in a light post structure with a polished rod section b. The base 1, the link step 1a and the guide post 5 are coaxially distributed.

The guide post 5 is sleeved with a disk-shaped gland 2, and the outer circumference surface of the gland 2 extends outwards to form workpiece clamping jaws 4 which are radially and uniformly distributed. The middle part of the upper bottom surface of each workpiece jaw 4 is provided with a notch 4a which is distributed corresponding to the link step 1 a. The midpoints of all the notches 4a are distributed on the same circumference.

The upper surface of the gland 2 is upwards protruded with a coaxially distributed counterweight circular table 2a, and the counterweight circular table 2a is provided with a through hole 2b correspondingly matched with the guide post 5. The nut 3 correspondingly matched with the threaded section a on the guide post 5 is arranged, and the gland 2 sleeved on the guide post 5 is locked by the nut 3.

The working process is as follows:

the base 1 is placed on a milling working surface, an annular blank 6 to be processed is sleeved on the link step 1a, the gland 2 is sleeved on the guide column 5 in a penetrating mode, the upper end face and the lower end face of the annular blank 6 are correspondingly clamped by the notch 4a of the workpiece clamping jaw 4 and the link step 1a, then the nut 3 is screwed, and the annular blank 6 to be processed is locked. And finally, starting milling operation. Since the midpoints of all the notches 4a are distributed on the same circumference, the circumferential degree of the arc surface on the inner side of the part 7 obtained by milling can be kept on the same circumference, and the machining accuracy is ensured.
