Abstract

The utility model relates to a fixture for a lathe. The fixture consists of a fixture body, a fastening screw, a pressure plate and a part. Key points are that: an inner hole for arranging the part and a mounting screw hole are formed in the fixture body; the aperture of the inner hole is 0.005 to 0.012mm larger than the external diameter of the small end of the part; a rubber backing plate is additionally arranged on the pressure plate; and the pressure plate and the part are connected and fastened on the fixture body through the fastening screw. The fixture for the lathe is simple in structure, and can be conveniently and quickly assembled and disassembled; the inner hole of the fixture is used for positioning, so that the fixture is high in positioning accuracy and convenient to operate; the rubber backing plate is arranged on the pressure plate, the part is slightly deformed when clamped, and can be machined at one time, and the machined part has high coaxiality of less than 0.02mm; and the quality of the product is stable, the assembly and disassembly time of the part is shortened, machining efficiency is improved, and the machining cost of the product is lowered.

Description

Lathe is used anchor clamps
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of lathe and uses anchor clamps.
Background technology
Working axiality requires high, and axiality requires to utilize the traditional lathe anchor clamps to add man-hour at 0.02 millimeter during with interior nonstandard part; Need the benchmark of first centering part one end, require it to beat, after processing less than 0.01 millimeter; Repeat said procedure, the reprocessing other end.The shortcoming of this processing method is: the part centering needs high skill and patience, and the centering spended time is long; Next is that this method processing parts quality stability is poor, and qualification rate is low, and processing cost is high.
Summary of the invention
The purpose of the utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, convenient mounting and clamping, stable processing quality, lathe that axiality is good to use anchor clamps.
The lathe of the utility model is used anchor clamps, comprises chuck body, clamp-screw, pressing plate and part, it is characterized in that: described chuck body is provided with the endoporus and installation screw that part is installed, and the aperture of endoporus is bigger 0.005~0.012 millimeter than part small end external diameter; Described pressing plate is provided with the rubber backing plate; Pressing plate is connected by clamp-screw with part and is fixed tightly on the chuck body.
The lathe of the utility model is simple with clamp structure, loads and unloads efficient and conveniently, adopts anchor clamps endoporus location, and positioning accuracy is high, and is easy to operate; Pressing plate is provided with the rubber backing plate, and the parts fixation distortion is little, once accomplishes the processing at part two ends, and the part axiality of processing is good, and axiality is less than 0.02 millimeter; Constant product quality has shortened the part lay day, has improved working (machining) efficiency, has reduced the product processing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure 1, chuck body, 2, pressing plate, 3, clamp-screw, 4, the rubber backing plate, 5, part, 6, installing hole, 7, screw is installed, 8, endoporus.
The specific embodiment
The lathe of the utility model is used anchor clamps, is made up of chuck body 1, clamp-screw 3, pressing plate 2 and part 5.Chuck body is provided with the endoporus 8 and installation screw 7 that part 5 is installed, and the aperture of endoporus 8 is bigger 0.01 millimeter than part 5 small end external diameters; Pressing plate 2 is provided with rubber backing plate 4.
The lathe of the utility model is to connect like this with anchor clamps: the small end of part 5 inserts in the endoporus 8 on the chuck body; The pressing plate 2 of band rubber backing plate 4 is pressed on the part 5; Clamp-screw 3 passes pressing plate 2, part 5 successively; Be screwed into the installation screw 7 on the chuck body, tighten clamp-screw 3, pressing plate 2 and part 5 are fixed tightly on the chuck body 1.
There are the anchor clamps of the utility model of part 5 to place on the jig platform of lathe clamping; Through the installing hole on the chuck body 16; Chuck body 1 is fixed tightly on the jig platform of lathe, just can have processed, after part 5 processes part 5; Only clamp-screw 3 and pressing plate 2 need be taken off, the part 5 that processes can be taken off.
