Description
Technical field
This utility model is related to a kind of stone tongs structure and in particular to a kind of revolving shell stone tongs structure.
Background technology
The operation principle of stone tongs is：Smoothly hold up or reliably clamp workpiece, using electric block or pneumatic flat
Weighing apparatus hang wait transfer equipment pass through rigging drive stone tongs, and then drive workpiece rising, translate, drop to specified location, so
Pass through afterwards to operate stone tongs to control transfer equipment simultaneously, make stone tongs remove workpiece, complete the handling process of workpiece.Lifting
Commonly use in fixture is the Special riggings such as suspension hook, steel wire rope, chain forcipated sling.Hoisting suction cup, clamp and pallet fork etc. can rise
Use for a long time as special hanger on heavy-duty machine, also can as removable auxiliary lifting appliance hang on suspension hook interim using it is also possible to
Magnechuck is drawn as magnetic conductivity materials such as borings.
For Engineering Machinery Components manufacturing company, for improve production efficiency, reduce the labor intensity of operator, lifting
The demand of fixture is requisite.But hoisting process Plays suspender can not meet all lifting demands, so must set
Count nonstandard suspender to realize lifting.For the design of nonstandard stone tongs, need the construction featuress according to part in actual use
And processing, service condition design different stone tongs.
Content of the invention
To be solved in the utility model be existing stone tongs poor universality technical problem.
In order to solve the above problems, this utility model provides a kind of structure of stone tongs it is characterised in that including set
Cylinder, the top of sleeve is inserted with push rod, and the upper end of push rod is connected with the suspension ring above sleeve；The bottom of sleeve is provided with cavity, should
It is provided with big steel ball, the lower end of push rod is exposed in cavity, and contacts with big steel ball in cavity；Wear in the side wall of lower cartridge
There are at least two small balls, small ball is located at the lower section of big steel ball, and contacts with big steel ball；Go out positioned at small ball outside sleeve
It is provided with O-ring.
Preferably, the outer wall of described sleeve is provided with for spacing ledge structure.
For improve production efficiency, reduce the labor intensity of operator, this utility model provides a kind of revolving shell and hangs
The design of clamps.Rotary shell part belongs to medium-and-large-sized, basic more than 20 kilograms of its weight, after such casing blank enters factory,
It is suitable for carrying out the coarse-fine Vehicle Processing of its cylindrical, endoporus and end face using large-scale vertical lathe, as carried by operator in the course of processing
If, during work-handling, labor intensity is larger, and danger is higher, and the suspender such as general suspension hook, suspender belt and suspension ring is all not
It is suitable for, so need to be according to the stone tongs of the size dimension of part, shape and processing situation design specialized.
The stone tongs structure that this utility model provides is simple, is not affected by workpiece blank hole molten error, is processed into
This is low, and its adjustable extent is larger, all applicable for revolution shells.
Brief description
A kind of structural representation of stone tongs structure that Fig. 1 provides for this utility model；
Fig. 2 is the sectional view in A-A face in Fig. 1；
Fig. 3 is schematic diagram during this utility model free state；
Fig. 4 is the sectional view of sleeve.
Specific embodiment
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As Figure 1-4, a kind of structure of the stone tongs providing for this utility model, this stone tongs expands for steel ball
Formula structure, this stone tongs includes sleeve 1, O-ring 2, push rod 3, suspension ring 4, big steel ball 5, small ball 6 form, three small balls 6
Uniformly it is arranged on sleeve 1.
Housing 7 is to be lifted workpiece, when fixture uses, by tightening of suspension ring 4, makes push rod 3 act on middle big steel ball 5
On, in the presence of big steel ball 5, three small balls 6 making periphery uniform are moved radially outwards, the blanking inner hole with housing 7
Fit tightly (as shown in Figure 1)；Lifting is sling suspension ring 4 by the suspension hook on electric block or balance crane, each steel ball props up
Prop up housing 7 to be lifted by crane, by housing 7 transfer to specified process equipment, after housing 7 is installed, unclamp suspension ring 4, hanging clamp
During carrying on tool, in the presence of housing 7 blanking inner hole, periphery small ball 6 inward hole moves, on middle part big steel ball 5
Move, you can take out stone tongs (as shown in Figure 3).
As shown in figure 4, sleeve 1 is provided with ledge structure 8, when workpiece put into by stone tongs, this ledge structure 8 lower surface
Contact with housing 7 inner face, can prevent fixture from dropping in workpiece.For improving intensity and the hardness of set letter 1, low-carbon (LC) selected by sleeve 1
Alloy steel material is processed through carburizing and quenching, simultaneously because screw thread position need to often be tightened and unclamps, after preventing screw thread position from hardening
Become fragile fragile, during heat treatment, permeability-reducing admixture is smeared at screw thread position, do not harden.Sleeve 1 is provided with the mounting groove of O-ring 2,
Using the elastic reaction of O-ring 2, when preventing from not lifting by crane workpiece, small ball 6 occurs and comes off from sleeve 1, the position to small ball 6
Put auxiliary positioning effect.
Push rod 3 is a cylindrical bar, and stone tongs can move up and down in using, and has relative motion with sleeve 1, so top
Bar 3 and sleeve 1 are set to gap cooperation, the quenched process of material selection steel alloy of push rod 1.
Suspension ring 4, big steel ball 5 and the equal selection standard part of small ball 6, are easy to purchase.
Stone tongs provided by the utility model, can eliminate the factor causing because of blank hole molten error, work piece hoisting
In front and back, by locking or unclamping suspension ring 4, in the presence of push rod 3, big steel ball 5 is made to move up and down, thus promoting small ball 6
Move radially, till making the fitting tightly of blanking inner hole of uniform three small ball 6 section and housing 7.
