Abstract
The utility model discloses a hoisting fixture for a precision-machined shaft workpiece, which can stably clamp a shaft workpiece, and can prevent the surface of the workpiece from being scratched to the greatest extent. The hoisting fixture for the precision-machined shaft workpiece, provided by the utility model, comprises an auxiliary fixing ring, wherein at least three through holes are formed in the side surface of the auxiliary fixing ring, and are uniformly distributed at the periphery of the auxiliary fixing ring; the axial lines of the through holes intersect the axial lines of the auxiliary fixing ring; bolts are mounted in the through holes. The hoisting fixture has the advantages that the structure is simple, the design is reasonable, the bolts can be propped against the precision-machined shaft workpiece, and the contact areas of the bolts and the workpiece are small; compared with the steel wire rope which directly hoists, the hoisting fixture greatly reduces the possibility of scratching the surface of the workpiece. In addition, through controlling the penetration length of the plurality of bolts, the hoisting fixture can adapt to hoisting shaft workpieces with different sizes, and is wide in application range.
Description
Technical field
The utility model belongs to mechanical part hoisting technology field, especially relates to a kind of for lifting the fixture of fine limit work axial workpiece.
Background technology
The fine limit work shaft-like workpiece, after machining, need to be lifted usually.When lifting fine limit work axial workpiece, often adopt the method lifting of steel rope oil bottle knot at present, but fine limit work axle class smooth surface, roughness is low, with the surface of the easy slip of steel rope lifting and scratch axle, and, after steel rope plucking workpiece, need polishing reparation even to scrap.And while in fitting process, needing vertical assembled shaft, oil bottle knots method and is difficult to aim at assembly center, also easy landing, cause workpiece surface damage, affected part quality.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of fine limit work shaft-like workpiece stone tongs, the gripping shaft-like workpiece can be stablized, and the scratch surface of the work can be avoided as far as possible.
In order to reach above purpose, the utility model provides following technical scheme:
A kind of fine limit work shaft-like workpiece stone tongs, comprise auxiliary set collar, described auxiliary set collar side has through hole, and described through hole is at least three and be uniformly distributed along auxiliary set collar periphery, through-bore axis and auxiliary set collar axes intersect, be equipped with bolt in through hole.
As a kind of improvement project of the present utility model, described bolt bottom is provided with pad.
As a kind of preferred version of the present utility model, described bolt side is provided with length scales.
As a kind of improvement project of the present utility model, described auxiliary set collar upper surface is provided with link.
As a kind of preferred version of the present utility model, described through hole is four.
As a kind of preferred version of the present utility model, there is the negative thread matched with the bolt outside thread in described through hole.
Compared with prior art, the utlity model has following technical scheme:
1. simple in structure, reasonable in design, bolt can prop up the fine limit work shaft-like workpiece, little with the workpiece area of contact, with the direct lifting mode of original steel rope, compares, and greatly reduces the possibility that surface of the work scratches.In addition, by controlling the length of going deep into of a plurality of bolts, the utility model can adapt to the shaft-like workpiece lifting of different size, applied widely.
2. pad can further play a protective role to surface of the work.
3. length scales is convenient to make a plurality of bolts to keep identical built-in length, guarantees that shaft-like workpiece and fixture do not produce bias, can not cause slippage because of centre-of gravity shift in hoisting process.
4. the link arranged on auxiliary set collar, steel rope easy to use coordinates this fixture to be lifted.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand the following specific embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometric centre.
Fine limit work shaft-like workpiece stone tongs as shown in Figure 1 and Figure 2, comprise auxiliary set collar 1, described auxiliary set collar 1 side has through hole 2, described through hole 2 is at least three and be uniformly distributed along auxiliary set collar 1 periphery, through hole 2 axis and auxiliary set collar 1 axes intersect, the interior bolt 3 that all is equipped with of each through hole 2.During lifting, only need as shown in Figure 3, fine limit work shaft-like workpiece 4 is placed to auxiliary set collar 1 central authorities, bolt 3 is tightened and is got final product on workpiece through through hole 2, note the symmetry of bolt 3 while tightening, built-in length should keep identical assurance shaft-like workpiece and fixture not to produce bias, in hoisting process, can not cause slippage because of centre-of gravity shift.As shown in Figure 4, during lifting, 8 one of steel ropes are hung on the lifting task that can complete shaft-like workpiece 4 on travelling crane hook 9 through auxiliary 1, one of set collar.Bolt 3 can prop up fine limit work shaft-like workpiece 4, little with workpiece 4 area of contact, with the direct lifting mode of original steel rope, compares, and greatly reduces the possibility of workpiece 4 surface tears.In addition, by controlling the length of going deep into of a plurality of bolts 3, the utility model can adapt to shaft-like workpiece 4 liftings of different size, applied widely.We know, general three bolts can form stable supported at three point, and bolt is more, support more stablely, but also for controlling a plurality of bolts, go deep into length and have unanimously brought more work capacity.In use procedure, find at the scene, four through holes and bolt have preferably stable holding effect.
As a kind of improvement project of the present utility model, as shown in Figure 5, described bolt 3 bottoms are provided with pad 5.Pad 5 can be made by the elastomeric material of the soft surfaces such as rubber, can further to surface of the work, play a protective role.
