Abstract
A kind of coaxial frock matched somebody with somebody for mm finishing mill unit cone box installed, it is characterised in that：The upper and lower working plate being fixedly connected including hollow support and with support, the bearing block that eight and countershaft component assembly are offered in upper frock plate surface fixes the size used, depth identical screwed hole in pairs, also offers the hole coordinated with countershaft component shaft part on upper and lower working plate respectively.What the utility model was opened up by upper frock plate surface fix in pairs with the bearing block of countershaft component assembly, and countershaft component assembly is fixed using screwed hole, being opened up by upper and lower working plate that it is installed with the cooperation of countershaft component shaft part hole.So as to ensure assembly precision improve operating efficiency, reduce operating personnel's labor intensity, reduce measurement when existing error the problems such as.
Description
Technical field
The utility model belongs to metallurgy industry steel rolling equipment technical field, and in particular to one kind is used for mm finishing mill unit cone box installed
The coaxial frock matched somebody with somebody.
Background technology
Cone case belongs to closed speedup draw box mechanism, is the core component of mm finishing mill unit.Case is bored by casing, power transmission shaft, spiral
Bevel gear pair, synchronous gear wheel set composition；Whole gears are Hardened gear face grinding worm, and axial modification, spiral bevel gear precision is 6
Level, cylindric spiral gear precision are 5 grades, to ensure that high-speed smooth operates, so requirement of the cone case to assembly precision and sealing is very
Strictly.Simultaneously because cone case working environment is severe (high temperature, water drenching, impact etc.), in process of production often because a variety of causes is made
Into random faule or damage parts, therefore it is higher to bore devan maintenance, the frequency of renewal part of case.If failure can not be repaired rapidly
Cone case, then mm finishing mill unit can be caused to shut down for a long time, influence the normal use of mm finishing mill unit.
The parts that include of cone case are more, and assemble fit precision and have a strict requirements, and process is cumbersome during assembling；Bore case
Countershaft component because using filmatic bearing, having certain interval between the diameter of axle and bearing working face in static state, this gap is to protect
Card in high-speed rotation is to form uniform oil film, and it is even that oil film when being worked if the bias of gap can have a became uneven, causes to moisten
Sliding harmful effect equipment operation, serious causes countershaft ablation locking, causes stopping accident.So how to ensure countershaft axle journal
Gap uniformity between filmatic bearing, lubrication when ensureing to run at high speed is well that industry expects solve the problems, such as a long time.
The content of the invention
The purpose of this utility model be to provide one kind can solve the problem that axle journal present in countershaft shafting assembling work mode with
The problem of gap is uneven between filmatic bearing, and it is simple to operate, it is same to improve matching somebody with somebody for mm finishing mill unit cone box installed for operating efficiency
Axle frock.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：Consolidate including hollow support and with support
Surely the upper and lower working plate connected, the bearing block that eight and countershaft component assembly are offered in upper frock plate surface are fixed in pairs
The size that uses, depth identical screwed hole, the hole coordinated with countershaft component shaft part is also offered respectively on upper and lower working plate.
Described upper and lower working plate is process using steel plate to be welded as a whole with support.
Described hollow support is circular configuration.
The aperture in the hole of described upper and lower working plate is fitted close with countershaft component shaft part.
The bottom surface of described lower working plate is higher than the end of countershaft component shaft part, that is, descends working plate bottom surface and countershaft component axle
There is a certain distance the end of section.
The bearing block fixed use in pairs with countershaft component assembly that the utility model is opened up by upper frock plate surface
Countershaft component assembly is fixed screwed hole, the hole pair coordinated with countershaft component shaft part opened up by upper and lower working plate
It is installed.So as to ensure assembly precision improve operating efficiency, reduce operating personnel's labor intensity, reduce measurement when
The problems such as existing error.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2,3 be two kinds of countershaft component assemblies of the utility model operating position figure；
Embodiment
Structural principle of the present utility model and operation principle are further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, the support 9 of the utility model including hollow circle configuration and the use being welded as a whole with support 9
The upper and lower working plate 10,11 that steel plate is process, eight axles with countershaft component assembly are offered on the upper surface of working plate 10
The bearing fixed size used, depth identical screwed hole in pairs, are also offered on upper and lower working plate 10,11 and countershaft respectively
The hole 12,13 that component shaft part coordinates, the aperture in the hole 12,13 of upper and lower working plate 10,11 and countershaft component shaft part are fitted close,
Referring to Fig. 3, the bottom surface of lower working plate 11 is higher than the end 14 of countershaft component shaft part, that is, descends the bottom surface of working plate 14 and countershaft component axle
There is a certain distance the end 14 of section.
Operating method of the present utility model is as follows：
The countershaft component mounting process of two kinds of different directions is identical, and as shown in Figure 2,3, countershaft component shaft part passes through
The hole 12,13 of upper and lower working plate 10,11, aperture and the countershaft component shaft part in the hole 13 of lower working plate 11 are fitted close, Er Qieyu
Frock lower steel plate bottom surface maintains a certain distance, and reaches axiality and examines purpose, then countershaft component is respectively by respective screw
Bearing block and upper working plate 10 of the component by the fixed joint shaft assembly of screwed hole 1,2,3,4 or 5,6,7,8, finally realize countershaft group
Whole axialities detection of part.
