Abstract

This utility model relates to an eccentric shaft jig, which belongs to the technical field of mechanical processing. The eccentric shaft jig mainly solves the problems that the technical requirement is high, the operation is complex, and the work efficiency is low because the positioning of the eccentric shaft is difficult and the division of dividing heads has errors easily in the processing by adopting the traditional processing method. The eccentric shaft jig is mainly characterized in that the eccentric shaft jig comprises a regular polygon jig body; an eccentric circle inner hole is formed on the regular polygon jig body, and a concentric circle shoulder inner hole is formed at one end of the eccentric circle inner hole; and screw holes are formed on the walls of the eccentric circle inner hole and the concentric circle shoulder inner hole. The eccentric shaft jig has the advantages that the overall design structure is simple, the conception is novel, the disassembly is convenient, the positioning and the dividing are accurate, and the work efficiency is high; and the effect of the eccentric shaft jig is very effective in small amount probation, the work efficiency can be improved by more than four times, and the eccentric shaft jig is particularly applicable to the mass production, and mainly to the jigs for eccentric shaft turning and milling.

Description

The eccentric shaft anchor clamps

Technical field

The utility model belongs to the Machining Technology field, is specifically related to a kind of eccentric shaft anchor clamps that are used for processing eccentric shaft part on milling machine, lathe.

Background technology

At present, processing eccentric shaft part does not have special eccentric shaft anchor clamps on milling machine, lathe, as mills six sides, all directions etc. of eccentric shaft.Because the outermost point in six sides of eccentric shaft, all directions etc. is consistent with the outermost point of the off-centre operation of eccentric shaft, indicator board, and traditional processing method location difficulty, and the dividing head calibration is made mistakes easily, thereby has specification requirement height, complicated operation, weak point that work efficiency is low.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure at above-mentioned weak point exactly, and is novel, easy accessibility, and the location, calibration is accurate, the eccentric shaft anchor clamps that work efficiency is high.

Technical solution of the present utility model is: a kind of eccentric shaft anchor clamps is characterized in that: comprise the regular polygon clamp body; This regular polygon clamp body is provided with the off-centre operation endoporus, and off-centre operation endoporus one end is provided with the concentric circles inner bore of step; This off-centre operation endoporus and concentric circles inner bore of step hole wall are provided with screw hole.

Regular polygon clamp body described in the utility model technical solution is that octagon is to positive ten hexagons.

The utility model adopt by the regular polygon clamp body and on the off-centre operation endoporus, the concentric circles inner bore of step, the eccentric shaft anchor clamps that screw hole on the hole wall constitutes, limit number on the regular polygon clamp body is corresponding with the limit number that eccentric shaft will mill, thereby on milling machine, add man-hour, earlier eccentric shaft is inserted in the regular polygon clamp body, the off-centre operation of eccentric shaft is in the off-centre operation endoporus, and be fixed with screw, only need then the chuck of milling machine is clamped on the polygon of regular polygon clamp body, just nature can guarantee to wait to mill the outermost point at position and the off-centre operation of eccentric shaft, the outermost point unanimity of indicator board.Compare traditional processing method, it is simple in structure, novel to the utlity model has global design, easy accessibility, the location, calibration is accurate, and the characteristics that work efficiency is high are on probation by small lot, effect is very desirable, can improve work efficiency more than 3 times, is specially adapted to produce in batches.The utility model is mainly used in the eccentric shaft car, mills the anchor clamps of processing.

Fig. 2 is that the C of eccentric shaft indicator board is to diagrammatic sketch;

Fig. 3 is that eccentric shaft six sides' D is to diagrammatic sketch;

Fig. 4 is a structural representation of the present utility model;

Fig. 5 is A of the present utility model-A cut-away view.

The specific embodiment

As shown in Figure 1 to Figure 3.What eccentric shaft 8 comprised the indicator board 6 of one end, middle off-centre operation 9, off-centre operation 9 both sides holds round 7 and six sides 10 of the other end.Six sides' 10 low order end requires consistent with the low order end of off-centre operation 9 and indicator board 6.

Extremely shown in Figure 5 as Fig. 4.The eccentric shaft anchor clamps comprise dodecagon clamp body 1, which is provided with off-centre operation endoporus 2 and concentric circles inner bore of step 3, and are respectively equipped with screw hole 4,5 on the hole wall of off-centre operation endoporus 2 and concentric circles inner bore of step 3.The dodecagon anchor clamps are used to mill six sides' 10 eccentric shaft.

The limit number of regular polygon clamp body is to wait to mill the eccentric shaft twice of limit number in many ways.Mill the four directions as eccentric shaft, then anchor clamps are octagon; If mill five sides, then be regualr decagon; If mill seven sides, then be positive ten quadrangles; If mill from all directions, then be positive ten hexagons.
