Technical field
The utility model relates to a kind of fixture, especially a kind of three-clove style for float grease seal blank turnery processing is pressed from both sides
Tool.
Background technique
Currently, the clamp structure for carrying out turnery processing to float grease seal blank is as follows: referring to Fig. 1, the fixture packet
The scroll chuck being made of chuck body 1 and three master jaws 3 is included, wherein sets that there are three the arrangements of 120 ° of angles each other on chuck body 1
T-shape slot 2, master jaw 3 is installed in T-shape slot 2, a fan-shaped claw 4 is fastened on each master jaw 3, and
Three fan-shaped correspondences of claw 4 are assembled into a circular dog plate, are equipped with several layers step on the end face of each fan-shaped claw 4
The arc of shape clamps position 5.
From the foregoing, it will be observed that above-mentioned dog plate realizes the clamping to the float grease seal blank of different model, but dog plate
It is to be clamped outward to it from interior, and on clamp structure be in the form of full folder along the inside of float grease seal blank
It is clamped.During actual processing, if float grease seal blank structure to be processed is irregular, such as the oil that floats
Blank showing ellipsoidal structure in structure is sealed, when dog plate in the form of full folder when being clamped, in order to ensure turnery processing
When concentricity usually oil sealing blank is clamped by dog plate, and carry out concentricity calibrating, this holds very much before processing
The prestressing force of malleable float grease seal blank, and after turnery processing is completed, and release is to the clamp position of workpiece, processing
Part can return to the original form, to be difficult to ensure the precision of turnery processing.
Summary of the invention
The purpose of this utility model seeks to solve currently during carrying out turnery processing to float grease seal blank,
Dog plate is easy to change the prestressing force of float grease seal blank in the form of full folder, so that workpiece can restore former after processing is completed
Shape, and the problem of influence the precision of turnery processing, a kind of three valves for float grease seal blank turnery processing are provided thus
Formula fixture.
The concrete scheme of the utility model is: a kind of three-clove style fixture for float grease seal blank turnery processing, packet
The scroll chuck being made of chuck body and three master jaws is included, wherein sets that there are three the arrangements of 120 ° of angles each other on chuck body
T-shape slot, master jaw are installed in T-shape slot；It is respectively arranged with adapter on each master jaw, and is opened up on each adapter
There are several screw holes radially arranged along chuck body；By in one holding claw of bolt fastening equipped with its screw hole on adapter
Portion, holding claw axisymmetricly arrange along the radial orientation where adapter, and the holding claw on three adapters be evenly arranged on it is same
On circumference；The arc-shaped structure of the inner side end of the holding claw, the both ends on the inside of holding claw are respectively provided with the protrusion for assisting putting forth effort.
Adapter described in the utility model is the block structure that cross section is in rectangle, is opened up on adapter there are three spiral shell
Hole；Adapter is secured it on master jaw by the bolt being mutually equipped with two screw holes therein；Adapter by with third
Holding claw described in the bolt fastening that a screw hole is mutually equipped with.
The utility model structure is simple, ingenious in design, it is ensured that float grease seal blank during processing concentric
Degree, effectively preventing blank, deformation occurs during processing, to improve the precision of its processing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of float grease seal blank clamp structure in the prior art；
Fig. 2 is the overlooking structure diagram of the utility model；
Fig. 3 is the structural schematic diagram of holding claw in the utility model.
In figure: 1-chuck body, 2-T-shape slots, 3-master jaws, 4-fan-shaped claws, 5-arcs clamp position, 6-switchings
Seat, 7-screw holes, 8-bolts, 9-holding claws, 10-protrusions, 11-blanks.
Specific embodiment
Referring to figure 2-3, a kind of three-clove style fixture for float grease seal blank turnery processing, including by 1 He of chuck body
The scroll chuck that three master jaws 3 are constituted wherein sets there are three the T-shape slot 2 of the arrangement of 120 ° of angles each other on chuck body 1, blocks
Pawl seat 3 is installed in T-shape slot 2；It is respectively arranged with adapter 6 on each master jaw 3, and if offering on each adapter 6
The dry screw hole 7 radially arranged along chuck body 1；A holding claw 9 is fastened by the bolt 8 being equipped with its screw hole on adapter 6
Middle part, holding claw 9 is axisymmetricly arranged along the radial orientation where adapter 6, and the holding claw 9 on three adapters is evenly arranged on together
On one circumference；The arc-shaped structure of inner side end of the holding claw 9, is respectively provided at the both ends of the inside of holding claw 9 for assisting
The protrusion 10 of power.
Adapter 6 described in the present embodiment is the block structure that cross section is in rectangle, is opened up on adapter 6 there are three spiral shell
Hole；Adapter 6 is secured it on master jaw 3 by the bolt being mutually equipped with two screw holes therein；Adapter 6 is by with
Holding claw 9 described in the bolt fastening that three screw holes are mutually equipped with.
The working principle of the utility model is as follows:
By technical solution it is found that when being fastened on scroll chuck to three holding claws 9, for tight on three adapters 6
Gu the screw hole of holding claw is on same circumference, so as to ensure the concentricity of three 9 clamping ends of holding claw (inside).In practical vehicle
When cutting work, each holding claw 9 is only contacted with one section of medial surface with the lateral surface of float grease seal blank 11, thus three
The mode that holding claw 9 is equivalent to three point contact clamps it along the lateral surface of blank 11, and this assures the oil that floats
It is enclosed in compactness when clamping, and work in-process not will receive the influence of the shape of blank 11, blank 11 will not be changed
Prestressing force and bring it about deformation；At the same time, during processing, if the prestressing force of blank 11 changes, and
When causing it that deformation takes place, each holding claw 9 can using the fastening point in the middle part of it as axle center carry out it is small and float adjust,
So that the concentricity of blank 11 during processing will not change, to improve the precision of its processing.
