Description

Drilling and milling integrated clamp special for hinge

Technical Field

The invention relates to a drilling and milling integrated clamp special for machining hinges, which has the advantages of rapid positioning, rapid clamping action, high production efficiency and high machining precision and stability.

Background

The special hinge needs to process the outer surface and the hole, and the matched surface roughness of the part is Ra3.2. In the prior art, the surface of the part is machined by a milling machine firstly, the principle of surface first and hole second is followed, then the hole is drilled, a common drilling tool firstly performs plane marking on the workpiece, the central position of the hole is determined, then a common drilling machine is used for machining, the workpiece needs to be repeatedly disassembled and assembled in different procedures, the method has low production efficiency and high technical requirements on operators, and the relative position positioning of the hole hardly meets the technical requirements.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides the special drilling and milling integrated clamp for machining the hinge, which has the advantages of quick positioning, quick clamping action, high production efficiency and high machining precision and stability.

In order to achieve the purpose, the invention adopts the technical scheme that: a drilling and milling integrated clamp special for a hinge comprises a clamp main body, a clamping mechanism and a positioning element; the clamp main body is L-shaped; the clamping mechanism comprises a clamping bolt, a fixed seat, a guide pillar, a stud bolt, a V-shaped clamping plate and a handle; the positioning element comprises a supporting nail and a limiting pin; a handle is arranged on the outer side of the vertical side of the clamp main body; the handle is provided with a spring, penetrates through the vertical side of the clamp body and is provided with a limit pin on the inner side of the vertical side of the clamp body; the upper part of the limiting pin is provided with a supporting nail; a fixed seat is arranged on the bottom edge of the clamp main body; the clamping bolt penetrates through the fixed seat, and the other side of the fixed seat is connected with the pushing plate; the pushing plate is provided with a guide pillar; a V-shaped clamping plate is arranged at the front end of the guide post; and the open end of the V-shaped clamping plate is provided with a stud bolt on the bottom edge of the clamp body.

Preferably, the guide posts are at least two.

Preferably, the guide post is provided with a return spring, and the return spring is connected with the pushing plate and the V-shaped clamping plate.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:

the drilling and milling integrated clamp special for the hinge is accurate in positioning and quick in clamping action, can complete positioning and assembling of parts at one time, can be used for drilling and milling two different machining procedures, ensures machining precision and stability of the machining precision, and is high in production efficiency.
