Description

Special bar double-thimble clamp for milling machine
Technical Field
The invention relates to the field of milling machine fixture design, in particular to a bar double-thimble fixture special for a milling machine.
Background
The common bar can be processed on a lathe, however, grooving and hole opening are difficult to be carried out on the circumferential surface of the bar in the traditional lathe processing process, so that a milling machine can be used for processing large batches of bar processing grooves and holes, a common fixture structure is used in the milling machine processing part process, bar clamping efficiency is low, the problems of inaccurate processing precision and the like exist, bar processing scrapping is further caused, and production efficiency is low.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defect of bar clamping of the existing milling machine, and provides a special bar double-thimble clamp for the milling machine, which has a simple structure, is practical and convenient, can solve the problem of bar clamping efficiency in the milling machine processing process, and can effectively solve the problem in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a double-thimble clamp for a bar special for a milling machine comprises a base, and a mounting plate, a left thimble and a right thimble which are arranged on the base; the mounting plate is provided with an air cylinder and is detachably connected with the air cylinder and the base; the cylinder is connected with the left thimble nut; the left thimble device is detachably connected with the right thimble device.
As a preferable scheme of the present invention, the mounting plate is connected to the cylinder and the base by a connecting bolt.
As a preferred scheme of the invention, the base is connected with the left thimble device through a mounting bolt a; the base is connected with the right thimble device through a mounting bolt b.
As a preferred scheme of the present invention, the left thimble device includes a left thimble base, a left sleeve and a left thimble; the left thimble is connected with the air cylinder through a nut.
As a preferred scheme of the present invention, the right thimble device includes a right thimble base, a right sleeve and a right thimble.
As a preferable scheme of the invention, the cylinder is matched with the ejector pin devices on two sides to realize the clamping of the final bar stock.
Compared with the milling machine fixture for the current bar stock, the milling machine fixture has the beneficial effects that: this special bar double-anchor clamps of milling machine, simple structure, control is convenient, and the clamping is efficient, cooperates with both sides thimble device through the cylinder, realizes that the bar presss from both sides tightly. The low bar machining efficiency is avoided, the shaking of the bar in the machining process is avoided, and the bar part machining quality is ensured.
