Abstract
The utility model discloses a quick disassembling wrench suitable for reducing a locking nut of a diameter-reducing roll collar taper sleeve, which comprises a handle and a ring, wherein holes are formed in four directions of the ring, teeth are connected in the holes and are formed by welding a threaded column and a rectangular block, and a stud penetrates through the hole in the ring and is fixed by a nut. The utility model can reduce the product quality fluctuation caused by the unbalance of the locknut when the locknut rotates at high speed due to the damage of the locknut; meanwhile, the damage of the reducing sizing mill set and the fault repair time caused by the damage of the locking nut are reduced, and the damage of the locking nut is reduced.
Description
Technical Field
The utility model relates to a wrench, in particular to a quick disassembling wrench suitable for reducing a locking nut of a diameter-reducing roll collar taper sleeve.
Background
When the reducing diameter high-speed steel roll collar is installed, a taper sleeve is firstly plugged into a hole of the roll collar, then the roll collar and the taper sleeve are sleeved on a roll shaft together, and finally the taper sleeve is fixed by screwing a locking nut through threads. The reducing diameter locking nut is provided with a threaded hole in the middle and a groove in each of the four directions at the top.
When tightening the fixed jam nut, the operator typically strikes one of the recesses of the jam nut with a bolt or other hard object. After multiple times of knocking, the locking nut is damaged from the groove, the locking nut is finally unbalanced in the high-speed rotating process, the product quality is fluctuated, and even the reducing sizing machine set is damaged.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to provide a quick disassembling wrench which is convenient, simple and labor-saving and is suitable for reducing the locking nut of the taper sleeve of the roll collar without damaging the locking nut in use.
The technical scheme is as follows: the utility model relates to a quick disassembling wrench suitable for reducing a locking nut of a taper sleeve of a sizing roller ring, which comprises a handle and a ring, wherein the handle is connected with the ring, holes are formed in four directions of the ring, teeth are connected in the holes and are formed by welding a threaded column and a rectangular block, and a stud penetrates through the hole in the ring and is fixed by a nut.
Further, the inner diameter of the ring is 125-130mm, which is slightly larger than the locking nut by 5 mm.
Further, the diameter of the hole is 5mm-50 mm.
Further, the diameter of the threaded column is 5mm-50mm, and the length of the threaded column is 10mm-100 mm.
Further, the size of the rectangular block is 1mm-2mm smaller than the size of the groove on the locking nut.
Furthermore, the tail end of the handle is provided with a hole for hanging.
Further, the handle and the ring are connected by welding.
Has the advantages that: compared with the prior art, the utility model has the following remarkable advantages: the utility model can reduce the product quality fluctuation caused by the unbalance of the locknut when the locknut rotates at high speed due to the damage of the locknut; meanwhile, the damage of the reducing sizing mill set and the fault repair time caused by the damage of the locking nut are reduced, and the damage of the locking nut is reduced.

Detailed Description
The technical scheme of the utility model is further explained by combining the attached drawings.
As shown in figure 1, the utility model relates to a quick disassembling tool suitable for reducing a locking nut of a taper sleeve of a diameter roller ring. Comprises an 11-ring; 12-a handle; 13-tooth, the inner diameter of the ring is slightly larger than that of the locking nut and is 127 mm. Holes with the diameter of 10mm are arranged on the ring in four directions. The tooth is formed by welding a threaded column and a rectangular block, the diameter of the threaded column is 10mm, the length of the threaded column is 50mm, and the length of the rectangular block is 10mm, 8mm and 5 mm. The screw bolt of the tooth is inserted into the hole on the ring and fixed by the nut, and the tooth can be replaced quickly after being worn. The handle is connected with the ring through welding, and the terminal trompil of handle is used for hanging.
As shown in fig. 2, where 21-the lock nut; 22-taper sleeve; 23-reducing the sizing roller ring; 24-a roll shaft; 25-reducing the diameter of the roller box, wherein the diameter of the locking nut is 125mm, and the top end of the locking nut has 4 grooves in all four directions.
As shown in figure 3, when in use, the tool is sleeved on the locking nut, the four teeth are placed in the four grooves on the locking nut, and the locking nut can be installed or disassembled by forcibly pulling or knocking the handle. Meanwhile, the four grooves of the locking nut are stressed uniformly, so that the grooves of the locking nut cannot be damaged.
