Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of flange four-jaw chuck, such as Fig. 1, including a disk 1.Disk 1 is arranged on lathe, and disk 1 is used for Being fixed flange to be processed, lathe is provided with the equipment such as the process tool that is processed flange, and disk 1 drives flange to rotate And it is processed.
The circle centre position of disk 1 is provided with a processing circular groove 16 caved inward.When flange is when cut, can produce a large amount of Heat, the surface at disk 1 center due to tight with Flange joint, the heat resulted in cannot dispersion quickly, by arranging Processing circular groove 16 add the space between disk 1 and flange, add the thermal diffusivity of disk 1, it is to avoid flange is because of overheated Damage.
The surface of disk 1 is provided with some grooves 20, and bar groove 20 is uniform along disk 1 center of circle, can increase the ventilative of disk 1 Property, when processing flange, heat radiation is faster, reduces flange and the temperature of disk 1 further.
The stationary plane of disk 1 is provided with four the first uniform guide rails 3 of the center of circle along disk 1, sets between adjacent first guide rail 3 There is the second guide rail 7.
Such as Fig. 1, in the first guide rail 3, it is provided with a slide block 4, the first guide rail 3 is formed the T-shaped space moved for slide block 4;Sliding Block 4 is provided with a positioning screw 6 extended to outside the first guide rail 3, and positioning screw 6 is vertical with slide block 4, positioning screw 6 End is provided with screw thread, is arranged with a nut 5 outside positioning screw 6, and nut 5 freely can regulate on positioning screw 6.
When flange is fixed on disk 1 by regulating block 2, first regulate the position of positioning screw 6, by right for positioning screw 6 Installing hole on quasi-flange, is contained in flange on positioning screw 6 and is fixed by nut 5.The three-point fix that positioning screw 6 is formed Structure, substantially reduces the error between the flange center of circle and disk 1 center of circle, and flange is high with the concentricity of disk 1, disk 1 and flange During rotation, flange is difficult to deflection, reduces the mismachining tolerance produced because of flange deflection.
Being provided with a screw mandrel 8 in second guide rail 7, screw mandrel 8 is provided with a regulating block 2 protruding on disk 1 outer surface. Such as Fig. 3, regulating block 2 is provided with a semi-circular recesses 9 coordinated with screw mandrel 8, is designed with and silk in groove 9 and the second guide rail 7 The screw thread that bar 8 coordinates.Regulating block 2 is placed on screw mandrel 8, is controlled its position by screw mandrel 8 transmission.
Regulating block 2 is provided with four fixed stations 17, and the height of fixed station 17 is outwards incremented by along disk 1 center of circle, each fixing The height of platform 17 is the most different.Being designed with flat surface 18 and arcwall face 19 on fixed station 17, the outer surface of flat surface 18 and flange supports Connecing, arcwall face 19 abuts with the outer peripheral face of flange.Meanwhile, arcwall face 19 is provided with the projection 21 of some increase frictional force.Outside Fixed station 17 can fix thicker flange, the fixed station 17 of inner side can fix relatively thin flange, fixing more firm to flange, method The practicality of blue four-jaw chuck is higher;Simultaneously compared to the bottom mounting flange at regulating block 2, fixed station 17 adds tune The range of accommodation of locking nub 2, regulating block 2 can the bigger flange of fixed dimension.
Screw mandrel 8 is provided with one section of threadless smooth department 13, and disk 1 is provided with the fixing seat 14 of a fixing screw mandrel 8, Gu Reservation 14 is provided with the arc surface 15 coordinated with smooth department 13, and fixing seat 14 can prevent screw mandrel 8 from the movement of front and back position occurring, as Fig. 2, fixing seat 14 is bolted with disk 1, convenient dismounting.
Such as Fig. 3, being provided with two protruding limited blocks 10 in the second guide rail 7, regulating block 2 is provided with joins with limited block 10 size The stopper slot 11 closed, limited block 10 makes regulating block 2 be fixed in the second guide rail 7, and only moves up the second guide rail 7 side, nothing Method is deviate from, and the rotational of screw mandrel 8 moves it.
The end of screw mandrel 8 is provided with operating side 12, and user passes through rotating operation end 12, makes screw mandrel 8 rotate.Screw mandrel 8 Fixed cannot move by fixing seat 14, the rotary motion of screw mandrel 8 is changed into the linear movement of regulating block 2, before and after regulating block 2 is carried out Mobile.Regulating block 2 abuts flange outer peripheral face, thus reaches the effect of mounting flange;When screw mandrel 8 does not rotates, regulating block 2 is not sent out Raw mobile;Rotating backward operating side 12, regulating block 2 unclamps flange, can take off flange.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but As long as all being protected by Patent Law in right of the present utility model.
