Abstract

The utility model relates to a mechanical machining clamp comprising an arc-shaped pressing plate, a locking screw rod, a middle locking opening and a nut, wherein the middle locking opening is arranged in the middle of the arc-shaped pressing plate, one end of the locking screw rod penetrates through the middle locking opening and is connected with the nut, the arc-shaped pressing plate is made of a 45# steel plate, the thickness of the steel plate is between 20 millimeters and 40 millimeters, the radian of the arc-shaped pressing plate is between 120 degrees and 180 degrees, the length of the arc-shaped pressing plate is between 300 millimeters and 500 millimeters, and the size of the middle locking opening is 20 mm*400 mm. Compared with the prior art, the mechanical machining clamp has the advantages of being simple in structure, small in size and low in weight, solving the problem that a sizing block with the same height as a workpiece needs to be assembled when the workpiece is locked during the machining process in the prior art, improving operation sensitivity, and improving use efficiency and operation strength of a machine tool.

Description

A kind of clamping tool for machine work
Technical field
The utility model relates to the Ferrous Metallurgy field of machining, is a kind of anchor clamps that use at machining equipment, particularly a kind of clamping tool for machine work.
Background technology
The important step of machine components in process be use anchor clamps whether rationally reliable, because volume of part differs in size, different, the different anchor clamps that adopt of device therefor are also different, therefore in process because one of problem that the problem that anchor clamps occur is our line technology personnel and operating personnel need to be solved always, existing anchor clamps are in use owing to be subjected to part dimension, the seat of shape and platen is controlled, it is time-consuming and loaded down with trivial details to operate, and has influence on the specification requirement of part processing, the operation turnover, utilization rate with equipment.
Therefore, a kind of clamping tool for machine work, simple to operate, effectively increased the flexibility of operation, improved lathe service efficiency and manipulation strength.
Summary of the invention
The purpose of this utility model be to provide a kind of can the general anchor clamps of realizing the clamping of some workpiece at different lathes.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of clamping tool for machine work comprises arc pressuring plate, tie down screw, middle fore shaft and nut, fore shaft in the middle of being provided with in the middle of the described arc pressuring plate, and fore shaft was connected with nut in the middle of tie down screw one end passed.
Described arc pressuring plate adopts the 45# steel plate, and steel plate thickness is between 20~40mm, and the arc pressuring plate radian is between 120 °~180 °, and arc pressing plate length is between 300~500mm.
Fore shaft is of a size of 20mm * 400mm in the middle of described.
Compared with prior art, the beneficial effects of the utility model are:
A kind of clamping tool for machine work has simple in structurely, and volume is little, lightweight characteristics, solve the problem that need to be equipped with when common workpiece is locked with the parallels of workpiece equal height in process, increased the flexibility of operation, improved lathe service efficiency and manipulation strength.
