Abstract
The utility model provides a disassembling tool for a middle guide locking screw of a sizing mill, which consists of a sleeve, a connecting rod and a pull rod; one end of the connecting rod is connected with the sleeve, the other end of the connecting rod is connected with a pull rod in a right-angle mode, and the front end of the sleeve is provided with a hexagonal nut groove. The utility model has simple and practical structure, convenient operation and labor saving, can quickly realize the installation and the disassembly of the locking screw without damaging the connecting thread of the locking screw and the equipment, not only shortens the maintenance time, and improves the operation efficiency; and bending of the locking screw can be avoided.
Description
Technical field
The utility model belongs to the Work tool field, is specifically related to a kind of specific purpose tool for the dismounting of guide and guard tie down screw and installation in the middle of the high-speed rod sizing mill.
Background technology
In the middle of the high-speed rod sizing mill, guide and guard tie down screw length is longer, and diameter is very thin, only has
10mm is thick.All adopt adjustable wrench or double offset ring spanner to be mounted and dismounted in the past, very easily caused tie down screw flexural deformation, can't dismounting.Especially local narrow and small, and tie down screw length is less than the roll protective cap, and adjustable wrench or double offset ring spanner all can't be put to good use, not only waste time and energy, inefficiency; And extended maintenance time, affect repair schedule.
Summary of the invention
The utility model aims to provide a kind of simple, can shorten the installation and removal time, avoids the middle guide and guard tie down screw of the sizing mill dismantling device of bent screws.
For this reason, the solution that the utility model is taked is:
In the middle of a kind of sizing mill, guide and guard tie down screw dismantling device, is characterized in that, sleeve, connecting rod and tommy bar, consists of; Connecting rod one end branch sleeve, other end right angle connects a tommy bar, and barrel forward end is provided with the hex nut groove.
Described connecting rod is diameter
12mm, length 120-150mm round steel.
Described tommy bar is diameter
12mm, length 800-120mm round steel.
Described sleeve outer diameter is
15-17mm.
The beneficial effects of the utility model are:
The utility model can be realized the installation and removal of tie down screw fast in the situation that do not damage tie down screw and equipment connection screw thread, not only can shorten the repair time, improves operating efficiency; And can avoid the bending of tie down screw.It is simple and practical, convenient operation and laborsaving.
The accompanying drawing explanation
Fig. 1 is tie down screw dismantling device front view;
Fig. 2 is tie down screw dismantling device left view.
In figure: tommy bar 1, connecting rod 2, sleeve 3, nut groove 4.
The specific embodiment
From accompanying drawing, in the middle of the utility model sizing mill, guide and guard tie down screw dismantling device system is comprised of tommy bar 1, connecting rod 2 and sleeve 3.Tommy bar 1 adopts
12 * 100mm round steel; Connecting rod 2 adopts
12 * 150mm round steel.Sleeve 3 external diameters are
16mm, front end is processed with hex nut groove 4, and the size of hex nut groove 4 is determined according to the tie down screw head dimensions is corresponding.After tommy bar 1, connecting rod 2, sleeve 3 machine, the rear end that tommy bar 1 one end flat-face fillet welds are received to connecting rod 2, then the front end of connecting rod 2 is welded on sleeve 3, make the special-purpose dismantling device of tie down screw of the utility model.
