Abstract

The utility model relates to a tool used on a turning machine or a milling machine, particularly to a tool for centring and clamping a large-scale rotational part on a turning machine or a milling machine. The tool comprise a base and jack catch bodies fixed to the base, and is characterized in that jack catch sliding blocks are movably mounted in sliding chutes of the jack catch bodies; jack catches are fixed on the jack catch sliding blocks through screws; a rotating disc is fixed on the base; three spiral grooves are formed on the rotating disc; the three jack catch bodies are movably fixed into the three spiral grooves through pins respectively; and a rotating bar is fixed on the rotating disc and provided with a rotating handle. The tool provided by the utility model has a simple structure and high clamping efficiency, is convenient and reliable in clamping, and is suitable for turning of various large-scale workpieces.

Description

Large revolving body part centering clamping tool
Technical field
The utility model relates to the frock of a kind of lathe or milling machine, specifically a kind of large revolving body part centering clamping tool of on lathe or milling machine, accomplishing.
Background technology
, lathe or milling machine generally all need use frock to clamp processed parts when carrying out machining.General now use three-jaw self-centering chuck comes clamping part.Existing three-jaw self-centering chuck maximum can only clamping 800mm, therefore factory's development in the past and the large revolving body part of producing, and the chucks that adopt carry out clamping more on vertical lathe; The chuck clamping; Need the position centering part of four claws of adjustment to realize centering, clamping needs centering, and spended time is long; And clamping is yielding, and clamping is unreliable.High to workman's specification requirement, be not suitable for producing in batches.Therefore inventing a kind of large-scale clamping tool is highly profitable.
Summary of the invention
The goal of the invention of the utility model is exactly that pin has the defective that the self-centering clamping exists in the revolving parts processing now, invents a kind of large revolving body part centering clamping tool, this device clamping efficient height, convenient mounting and clamping, clamping precision height.
The technical scheme of the utility model is achieved in that it comprises base and is fixed on the jaw body on the base; It is characterized in that: the claw slide block is equipped with in activity in the chute of jaw body, is fixed with claw through screw on the claw slide block, is fixed with rotating disk on the base; Rotating disk is provided with three helicla flutes; Three jaw body are fixed in three helicla flutes through the activity of pinning respectively, are fixed with dwang on the rotating disk, and turning handle is housed on the dwang.
During parts fixation, the rotated handle drives dial rotation by dwang, and three helicla flutes on the rolling disc drive three claw slide block movements through pin, and the clamping to part is accomplished in motion when accomplishing three claws.This frock clamping movement travel is short; The different parts that the clamping size disparity is bigger can be realized with the different location of claw slide block through claw 4; Can realize that also the utility model is applicable to the quick centering clamping of the workpiece of diameter phi more than 800 through processing different claws.
The utility model is simple in structure, and clamping efficient is high, and convenient mounting and clamping, reliable is applicable to the turning processing of various large-scale workpieces.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the vertical view of Fig. 1
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
Like Fig. 1, shown in Figure 2, the utility model comprises base 1 and is fixed on the jaw body 5 on the base 1 through screw that claw slide block 2 is equipped with in activity in the chute of jaw body 5; Be fixed with claw 4 through screw 3 on the claw slide block 2; Be fixed with rotating disk 7 on the base 1, rotating disk 7 is provided with 8, three jaw body 5 of three helicla flutes and is fixed in three helicla flutes 8 through 6 activities of pinning respectively; Be fixed with dwang 9 on the rotating disk 7, turning handle 10 is housed on the dwang 9.
During parts fixation, rotated handle 10 drives rotating disks 7 by dwang 9 and rotates, and three helicla flutes 8 on the rotating disk 7 drive 2 motions of three claw slide blocks through pin 6, motion when accomplishing three claws 4, and completion is to the clamping of part.This frock clamping movement travel is short; The different parts that the clamping size disparity is bigger can be realized with the different location of claw slide block 2 through claw 4; Also can realize that contact area is big during clamping through processing different claws, clamping force improves greatly; Clamping and process time significantly reduce, and working (machining) efficiency significantly improves.
