Mechanical machining fixture with stable clamping force

Abstract

The invention discloses a mechanical machining fixture with stable clamping force and belongs to the technical field of mechanical machining. A first plate body and a second plate body of the fixtureare both arranged on a base, a rotating ring is slidably connected inside a through hole of the first plate body, the right side surface of the rotating ring is provided with one first fixture body, the left side surface of the rotating ring is provided with one second fixture body, the side surface, close to the first plate body, of a pushing plate is provided with one first fixture body and onesecond fixture body correspondingly, first fixed blocks of the first fixture bodies are fixed to the rotating ring, the first fixed blocks are provided with second threaded holes, second threaded pushing rods penetrate through the second threaded holes to be movably connected with arc-shaped clamping parts, second fixed blocks of the second fixture bodies are fixed to the rotating ring, the secondfixed blocks are provided with third threaded holes, and third threaded pushing rods penetrate through the third threaded holes to be movably connected with V-shaped clamping parts. The mechanical machining fixture with the stable clamping force performs clamping firmly, can meet clamping of workpieces of different specifications and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machining fixture with stable clamping force. Background technique [0002] The fixture is a device used to fix the processing object in the machining process so that it occupies the correct position to accept construction or inspection. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures.

Problems solved by technology

[0003] When the current lathes process long bar workpieces of different specifications, because the bar workpieces are generally long and heavy, the farther they are from the processing end, the more the workpiece hangs downwards, making it difficult to guarantee the dimensional accuracy requirements of the processed workpieces. It is necessary to clamp workpieces of different specifications through fixtures. It is difficult for fixtures to not only clamp workpieces stably and reliably

Secondly, there are not only round bars, but also angular bars such as hexagonal bars. The clamping tools for round bars cannot clamp hexagonal bars stably and reliably, and it is often necessary to make round bars and bars separately. The special fixture for hexagonal bar, on the one hand, causes waste of cost, on the other hand, it needs to be replaced according to the type of bar, which is troublesome
