Abstract
A kind of protective device of rotor detecting core shaft, comprise and deposit pipe (1) and mandrel (2), the lower end sleeve of mandrel (2) is depositing in pipe (1), the upper end of mandrel (2) is plugged in the pipe box (3) that cross section is circular arc, be spirally connected crown cap (4), lower end of the upper end of pipe box (3) is bolted with inner screw sheath (5), and the lower end of inner screw sheath (5) is screwed onto deposits on pipe (1); The groove of moulding annular on the described madial wall of depositing pipe (1), deposits in the groove of pipe (1) and is pasted with annular sponge ring (7); On described pipe box (3), be plugged with rubber sleeve (6).It can avoid colliding with of mandrel not using, and it has avoided the impact of hand perspiration on mandrel simultaneously, has reduced the situation of getting rusty, thereby has extended the serviceable life of mandrel.
Description
Technical field:
The utility model relates to the technical field of rotating shaft pick-up unit, more specifically to a kind of protective device of rotor detecting core shaft.
Background technology:
At present on the production assembly line of refrigerator press, there is hot jacket rotor one procedure, before hot jacket rotor, first need to detect it and treat with detecting core shaft the rotating shaft internal diameter of hot jacket.Its detecting core shaft accuracy requirement is higher, but the mandrel in first assembling process is just simply placed on worktable, thereby easily cause colliding with and affected by hand perspiration or humid air and getting rusty of mandrel, not only affect its testing result, and directly cause scrapping of mandrel when serious.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of protective device of rotor detecting core shaft is provided, and it has reduced the situation of colliding with and getting rusty of mandrel, has extended the serviceable life of mandrel.
Technology solution of the present utility model is as follows:
A kind of protective device of rotor detecting core shaft, comprise and deposit pipe and mandrel, the lower end sleeve of mandrel is depositing in pipe, and the upper end of mandrel is plugged in the pipe box that cross section is circular arc, be spirally connected crown cap, lower end of the upper end of pipe box is bolted with inner screw sheath, and the lower end of inner screw sheath is screwed onto deposits on pipe; The groove of moulding annular on the described madial wall of depositing pipe, deposits in the groove of pipe and is pasted with annular sponge ring; On described pipe box, be plugged with rubber sleeve.
Described inner screw sheath is made up of upper and lower two groups of screw threads, and the upper and lower screw thread of inner screw sheath is contrary screw thread.
The upper and lower side of the rubber sleeve on described pipe box leans against respectively on top cap and inner screw sheath.
The internal diameter of described pipe box is less than the diameter of mandrel, and the diameter of mandrel is greater than the internal diameter of sponge ring, and the length of mandrel is less than pipe box and deposits the length sum of pipe.
On the described outer wall of depositing pipe, be fixed with mounting bracket.
The beneficial effects of the utility model are:
It can avoid colliding with of mandrel not using, and it has avoided the impact of hand perspiration on mandrel simultaneously, has reduced the situation of getting rusty, thereby has extended the serviceable life of mandrel.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model;
Fig. 3 is the enlarged diagram in Fig. 2 of the present utility model.
In figure: 1, deposit pipe; 2, mandrel; 3, pipe box; 4, top cap; 5, inner screw sheath; 6, rubber sleeve; 7, sponge ring; 8, mounting bracket.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of protective device of rotor detecting core shaft, comprise and deposit pipe 1 and mandrel 2, the lower end sleeve of mandrel 2 deposit pipe 1 in, the upper end of mandrel 2 is plugged in the pipe box 3 that cross section is circular arc, be spirally connected crown cap 4, lower end of the upper end of pipe box 3 is bolted with inner screw sheath 5, and the lower end of inner screw sheath 5 is screwed onto deposits on pipe 1; On the described madial wall of depositing pipe 1, the groove of moulding annular, deposits in the groove of managing 1 and is pasted with annular sponge ring 7; On described pipe box 3, be plugged with rubber sleeve 6.
Described inner screw sheath 5 is made up of upper and lower two groups of screw threads, and the upper and lower screw thread of inner screw sheath 5 is contrary screw thread.
The upper and lower side of the rubber sleeve 6 on described pipe box 3 leans against respectively on top cap 4 and inner screw sheath 5.
The internal diameter of described pipe box 5 is less than the diameter of mandrel 2, and the diameter of mandrel 2 is greater than the internal diameter of sponge ring 7, and the length of mandrel 2 is less than pipe box 3 and deposits the length sum of pipe 1.
On the described outer wall of depositing pipe 1, be fixed with mounting bracket 8.
Principle of work: set its pipe box 3 of protective device of the utility model can be served as handle arrangement; use is directly held in 3 of pipe boxes and can avoids the impact of hand perspiration on mandrel; and can deposit some lithium base greases of pipe 1 placement simultaneously; when mandrel 2 is extracted out, antirust grease is stopped by sponge ring; can smear the uniform oil film of one deck at mandrel 2 again, more can prevent from getting rusty simultaneously.
