Abstract
The invention relates to a sling for hoisting of a cylindrical stepped hole workpiece, and the sling can be used for lifting a smooth cylindrical workpiece. A positioning cylinder is equipped with an eccentric through-hole, a threaded hole and an arc through-groove, a lifting hook passes through the eccentric through-hole of the positioning cylinder to be connected to a hook plate, and the positioning cylinder cooperates with the stepped hole of the workpiece to realize positioning. The hook plate is provided with an eccentric hole, is in connection with the lifting hook through a nut and is stuck in the arc through-groove of the positioning cylinder. A cover plate for fixing the positioning cylinder and a return spring is sleeved on the lifting hook, and is fixed on the upper surface of the positioning cylinder through a bolt. The return spring is positioned on the lifting hook by a cylindrical pin. The sling provided by the invention can accurately control the lifting point of the smooth cylindrical workpiece, and after lifting, the workpiece does not slip, thus being safe and reliable. After lifting, the workpiece can maintain a horizontal state, during hoisting, the workpiece is table, bump phenomenon does not occur, and the product quality is ensured. The sling is easy to operate, and can meet the hoisting of a variety of cylindrical workpieces.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially for smooth outer surface and the inside suspender that has step hole workpiece to lift.
Background technology
When assembling automotive axle assembly, many cylindrical works are had to join use at the enterprising luggage of assembly.In the manufacturing process of cylindrical work, need steadily to hang this its to get.Due to its contour structures smoother, not easily using suspender to carry out hanging getting, is more carry out handling to it after using hook cylindrical work endoporus.But this kind of easy suspension hook has just been sling workpiece, can not guarantee steady handling, and workpiece easily slippage from lifting hole(eyelet) in the process of handling, there is larger potential safety hazard.Meanwhile, by the easy deflection of ordinary lifting hook handling cylindrical work, cause accurately workpiece being placed on working position apparatus, usually there will be phenomenon of colliding with, affect product design.
Summary of the invention
For solving existing suspender to the not steady and unsafe problem of cylindrical work lifting, goal of the invention of the present invention is to provide a kind of suspender for the lifting of cylindrical step hole workpiece, can handling cylindrical component safely and reliably, lift by crane safe and reliable, handling is steady.
For achieving the above object, positioning cylinder of the present invention is with eccentric through-hole, tapped bore and circular arc groove, and suspension hook is connected with hook plate by nut through the eccentric through-hole of positioning cylinder, and positioning cylinder coordinates with the stepped hole of workpiece and realizes locating; Hook plate is with eccentric orfice, and hook plate is connected with suspension hook by nut, and is stuck in the circular arc groove of positioning cylinder; Cover plate for stationary positioned cylinder and pull back spring is enclosed within suspension hook, is bolted on the upper surface of positioning cylinder; Pull back spring is positioned on suspension hook by straight pin.
Described hook plate is the trapezoidal plate of semi arch, and the eccentric throw of its eccentric through-hole is consistent with the eccentric throw of the eccentric through-hole on positioning cylinder.
During lifting cylindrical work, hook plate relative positioning cylinder forms a cylinder (being called initial position), and under the effect of pull back spring, hook plate is close in the circular arc groove of positioning cylinder.Whole suspender is inserted in the stepped hole of workpiece, fit in cover plate and the workpiece upper surface of suspender, downward pressing suspension hook also revolves turnback, under the effect of eccentric orfice, hook plate protrudes cylindrical one segment distance of positioning cylinder, during hoisting sling, hook plate projection supports the step surface of stepped hole, and the cylindrical of positioning cylinder contacts with inner hole of workpiece, achieves the hoisting function of whole workpiece.
The present invention compared with prior art, has the following advantages:
1, the Heave Here of smooth cylinder workpiece can accurately be controlled, after lifting, workpiece not slippage, safe and reliable.
2, after lifting by crane workpiece, workpiece can be made to keep horizontality, and in handling process, workpiece is steady, there will not be phenomenon of colliding with, ensure that the quality of product.
3, easy and simple to handle, the lifting of multi items cylindrical work can be met.
