Extend the bottom of vertical plane two.
Preferably, the surface of the frock main body is provided with carburized layer.
Preferably, the surface of the cylindrical portion is along the circumferential direction provided with the rough layer of annular, and the rough layer is used to coordinate
Maintenance tool uses.
The beneficial effects of the utility model are as follows：
Frock described in the utility model by first half and it is latter half of involute, when being assembled on hydraulic cylinder rod, first half
Portion and latter half of pairing are connected, and hydraulic cylinder rod surface will not be caused to damage in installation process, during dismounting, only need pine
Open the annexation of left fixing bolt and right fixing bolt, you can open first half and latter half of, thus, avoided in unloading process
Brute-force dismounting so that frock described in the utility model effectively plays protective action, will not cause extra damage.Further
Ground, left round plate of the present utility model devise the Access Division being engaged with hydraulic cylinder rod end construction so that and it is fixed, prevent
Only in the course of work of hydraulic cylinder rod, protective tooling loosens, and influences equipment operation；Oozed on the surface of protective tooling
Carbon processing, the carburized layer on surface can play cure process effect.In addition, found during on probation, the dimension such as spanner or pipe wrench
The abrasion on protective tooling surface can be caused by repairing the use of instrument, get off to cause the part of carburized layer to peel off for a long time, therefore this practicality
New further to devise annular rough layer, the rough layer is obtained by carrying out coarse processing on the surface of cylindrical portion, coarse
The mode of processing includes setting some grooves or frosted processing, and after so designing, when maintenance work is carried out, spanner or pipe wrench exist
The position of rough layer uses, and on the one hand facilitates the application of active force, improves the operating efficiency of spanner or pipe wrench, on the other hand may be used
To protect protective tooling, its service life is effectively extended.The utility model had not both interfered with the normal operation of hydraulic cylinder rod,
And can protects hydraulic cylinder rod in maintenance, and the effect of being effectively protected can be played to the mechanical oil seal of the opening position, practical.
