Description
Technical field
The invention belongs to the processing and manufacturing technology of railway electric locomotive hollow axle wheel set set, and in particular to a kind of electric power
Locomotive hollow shaft sleeve bearing block is ground clamping position frock.
Background technology
SS8 type electric locomotive hollow shafts are the critical components of diesel locomotive wheel pair, half cavity body axle class of category, complicated,
The accuracy of manufacture is high.Its bearing block dimensional tolerance is 0.05mm, circle bounce is 0.05mm, because hollow axis center is that cavity structure can not
Clamping lathe, it is impossible to meet grinding technique demand.This requires to design a kind of frock for aiding in manufacture, to meet high-precision axle
The demand of the manufacturing process of bearing.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned problem and shortage, there is provided it is a kind of reasonable in design, it is economical, just
Victory, improve the electric locomotive hollow shaft sleeve bearing block grinding clamping position frock of product manufacturing precision and operating efficiency.
To reach above-mentioned purpose, adopted the technical scheme that：
A kind of electric locomotive hollow shaft sleeve bearing block is ground clamping position frock, including support axis body, and the support axis body is worn
In hollow shaft sleeve, multiple adjustment screws are laid with the support axis body, is matched in the adjustment screw and is provided with adjustment top
Silk；Backstop disk, the backstop disk is fixedly installed on the front end of support axis body, and the leading section of the hollow shaft sleeve is pasted with backstop disk
Close positioning；And supporting plate, the supporting plate is semicircular arc, and supporting plate is connected into the domain with hollow shaft sleeve；At least one institute
Adjustment jackscrew is stated to be arranged between the supporting plate and support axis body, other adjustment jackscrews be laid in support axis body with it is empty
Between the inwall of spindle sleeve.
The support axis body rear end is provided with shift fork screw, and is provided with shift fork bolt in the shift fork screw.
The backstop disk and support axis body interference fit.
6 ~ 10 adjustment screws are laid with the support axis body.
Using above-mentioned technical proposal, acquired beneficial effect is：
Design structure of the present invention is reasonable, using simple, conveniently, can effectively meet the design requirement of hollow shaft sleeve bearing block,
The accuracy of manufacture of electric locomotive hollow shaft sleeve is can guarantee that, manufacturing cost is saved using existing equipment, greatly improves work effect
Rate.
The present invention is based on existing product material, with reference to the improvement of the manufacturing process of hollow shaft sleeve, it is achieved thereby that a kind of
Economic, easily tool structure design so that it can effectively reduce production cost, during positioning clamping is carried out, greatly
Labor intensity is reduced greatly, so as to realize the processing and manufacturing of hollow shaft sleeve bearing block.

Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 5, a kind of electric locomotive hollow shaft sleeve bearing block grinding clamping position frock of the present invention, hollow shaft sleeve
2001 include two parts, and a portion semicircular in shape hollow shaft structure, another part is the sky in hollow completely circular structure
Mandrel sleeve-bearing, the hollow shaft sleeve can not directly fix the processing that clamping carries out bearing block on cylindrical grinder, it is therefore desirable to
Design corresponding frock and solve the bearing block grinding manufacture of the hollow shaft sleeve.Electric locomotive hollow shaft sleeve bearing block in this implementation
Being ground clamping position frock includes support axis body 1001, backstop disk 1004 and supporting plate 1005, and support axis body 1001 is located in sky
In spindle sleeve 2001, support and 8 adjustment screws 1002 are laid with axis body 1001, matched in adjustment screw 1002 and be provided with tune
Whole jackscrew 1003；Backstop disk 1004 is fixedly installed on the front end of support axis body 1001, and the leading section of hollow shaft sleeve 2001 is with stopping
The fitting positioning of block plate 1004；Supporting plate 1005 is semicircular arc, and supporting plate 1005 is connected into the domain with hollow shaft sleeve 2001；Extremely
Few adjustment jackscrew 1003 is arranged between supporting plate 1005 and support axis body 1001, and others adjustment jackscrew 1003 is laid in
Support between axis body 1001 and the inwall of hollow shaft sleeve 2001, support axis body rear end is provided with shift fork screw 1006, and shift fork
Shift fork bolt 1007 is provided with screw 1006, backstop disk 1004 is interference fitted with support axis body 1001.
In specific implementation process：After first axis body being supported to require that interference fit is good with stop disk opsition dependent, by 8
Bar adjusts jackscrew and 1 shift fork bolt and is arranged on request in the adjustment screw supported on axis body, then with hollow shaft sleeve opsition dependent
It is required that assembling, cylindrical grinder is loaded after supporting plate has been fixedly mounted with attachment bolt and is clamped, you can completes hollow shaft sleeve bearing
Seat grinding process, ensure the accuracy of manufacture of bearing block.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention
