The structure of the cold rolling device of bearing ring can obtain and understand from the utility model of the disclosed a kind of short cylindrical roller bearing outer ring cold-rolling machine device of Chinese patent announcement CN202291177U; Cylindrical roller bearing outer ring cold-rolling machine is the cold rolling machine of bearing ferrule blanks; The blank of bearing ferrule blanks is fixed on the roll milling wheel outside main shaft and is positioned under the mutual spreading of core roller of blank inner side and expand until meet the requirements of diameter gradually laying respectively at blank gusset outside; The bearing ferrule blanks of cold rolling different size need to be changed different roll milling wheels; There is the deficiency of roll milling wheel disassembling, assembling and replacing difficulty in the main shaft device of the cold rolling machine of current bearing ferrule blanks; Therefore, design a kind of roll milling wheel disassembling, assembling and replacing main shaft device of the cold rolling machine of bearing ferrule blanks easily, become problem demanding prompt solution.
Utility model content
The purpose of this utility model is in order to overcome the main shaft device of the cold rolling machine of current bearing ferrule blanks, to have the deficiency of roll milling wheel disassembling, assembling and replacing difficulty, and a kind of roll milling wheel disassembling, assembling and replacing main shaft device of the cold rolling machine of bearing ferrule blanks is easily provided.
Concrete technical scheme of the present utility model is:
The main shaft device of the cold rolling machine of a kind of bearing ferrule blanks, comprise the main shaft being formed by the transmission section connecting successively, the first linkage section, baffle ring section, canned paragraph and the second linkage section, the first holder with the first linkage section pivot joint, with the roll milling wheel that canned paragraph is in transmission connection, the round nut that blocks roll milling wheel and be threaded with canned paragraph; The axle sleeve mating with the second linkage section, with the second holder of axle sleeve pivot joint, the baffle plate that blocks axle sleeve and be fixedly connected with the second linkage section.When the main shaft device of the cold rolling machine of this bearing ferrule blanks is used, when needs, change roll milling wheel, pull down baffle plate, pull down axle sleeve and drive and pull down the second holder, screw out round nut, just can pull down roll milling wheel and change.The main shaft device roll milling wheel disassembling, assembling and replacing of the cold rolling machine of this bearing ferrule blanks is convenient.
As preferably, the second described linkage section is provided with frustum section; The interior gusset of axle sleeve is the frustum hole of mating with frustum section.Make roll milling wheel disassembling, assembling and replacing more convenient.
As preferably, the second described holder is provided with the transition seat that compresses first holder one end.Improve the integral rigidity of the main shaft device of the cold rolling machine of bearing ferrule blanks.
As preferably, outside, the outer end of described baffle plate be provided be fixedly connected with the second holder stifle.Prevent that dust from entering pivot joint position.
Compared with prior art, the beneficial effects of the utility model are: one. the main shaft device roll milling wheel disassembling, assembling and replacing of the cold rolling machine of this bearing ferrule blanks is convenient.Two. frustum section and frustum hole make roll milling wheel disassembling, assembling and replacing more convenient.Three. transition seat improves the integral rigidity of the main shaft device of the cold rolling machine of bearing ferrule blanks.Four. stifle.Prevent that dust from entering pivot joint position.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: main shaft-1, transmission section-11, the first linkage section-12, baffle ring section-13, canned paragraph-14, the second linkage section-15, frustum section-16, the first holder-2, roll milling wheel-3, round nut-4, axle sleeve-5, frustum hole-51, the second holder-6, baffle plate-7, transition seat-8, stifle-9.
The specific embodiment
Below in conjunction with shown in accompanying drawing, the utility model is described further.
As shown in Figure 1: the main shaft device of the cold rolling machine of a kind of bearing ferrule blanks, comprise the main shaft 1 being formed by the transmission section 11, the first linkage section 12, baffle ring section 13, canned paragraph 14 and the second linkage section 15 that connect successively, pass through the first holder 2 of bearing hinge joint with the first linkage section 12, with the roll milling wheel 3 that canned paragraph 14 keys are connected, the round nut 4 that blocks roll milling wheel 3 and be threaded with canned paragraph 14; The axle sleeve 5 mating with the second linkage section 15, passes through the second holder 6 of bearing hinge joint, the baffle plate 7 that blocks axle sleeve 5 and be connected with the second linkage section 15 screws with axle sleeve 5.
The second described linkage section 15 has frustum section 16; The interior gusset of axle sleeve 5 is the frustum hole 51 of mating with frustum section 16.
The second described holder 6 has the transition seat 8 that compresses first holder 2 one end.
The outer end outside of described baffle plate 7 have be connected with the second holder 6 screws stifle 9.
