Description
Technical field
The utility model relates to a kind of installation tool of bearing, in particular to the small bearing erector of a kind of instrument and meter
Tool.
Background technique
Bearing used is especially small in many precision instrumentations, bearing bore diameter having a size of 1mm ~ 3mm, outer diameter be 3mm ~
The installation of 8mm, bearing use plain bearing tool, such as hook spanner, hydraulic nut, and it is uncomfortable to pad sleeve of spun gold pad etc.
With and bearing is as important spare part a kind of in precision instrumentation, and the quality of installation whether influences precision instrumentation
Precision, service life and performance.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides that a kind of structure is simple, easy for installation, work efficiency is high
The small bearing installing tool of instrument and meter.
The technical solution that the utility model solves the above problems is: a kind of small bearing installing tool of instrument and meter, including
Core bar and expansion set, the expansion set are cylinder, and the inner hole hole wall of expansion set is equipped with internal screw thread, and core bar is equipped with matches with the internal screw thread
The external screw thread of conjunction；Axially be provided with a plurality of expansion slot in the expansion set front end side wall, the core bar front end be diameter from back to front by
Decrescence small taper platform, the conical surface of taper platform enable to expansion set diameter to swell.
The small bearing installing tool of above-mentioned instrument and meter, the core bar are the multi-diameter shaft that diameter is gradually reduced.
The small bearing installing tool of above-mentioned instrument and meter, the internal via shape of the expansion set are the ladder to match with multi-diameter shaft
Shape.
The diameter of the small bearing installing tool of above-mentioned instrument and meter, the taper platform front end face is less than expansion set inner hole front end
Diameter, the diameter of taper platform rear end face are greater than the diameter of expansion set inner hole front end.
The small bearing installing tool of above-mentioned instrument and meter, the core bar posterior face are equipped with reticulate pattern.
The small bearing installing tool of above-mentioned instrument and meter, the expansion set are gradually reduced ladder-like in diameter from back to front.
The utility model has the beneficial effects that: the utility model is by the cooperation of core bar and expansion set, using expansion set principle,
Guaranteeing the lean and correct assembly of bearing outer ring and bearing saddle bore, there is entire installation tool structure to be simple and convenient to operate easily a little,
It improves work efficiency and work quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of core bar in Fig. 1.
Fig. 3 is the structural schematic diagram of expansion set front end in Fig. 1.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1-Figure 3, the small bearing installing tool of a kind of instrument and meter, including core bar 1 and expansion set 2, the expansion set 2
For cylinder, the inner hole 2-1 hole wall of expansion set 2 is equipped with internal screw thread, and core bar 1 is equipped with the external screw thread with the screw-internal thread fit；Institute
It states and is axially provided with a plurality of expansion slot 2-2 in 2 front end side wall of expansion set, 1 front end of core bar is what diameter was gradually reduced from back to front
Taper platform 1-2, the conical surface of taper platform 1-2 enable to 2 diameter of expansion set to swell, and 1 posterior face of core bar is equipped with reticulate pattern 1-3.
As shown in Fig. 2, the core bar 1 is the multi-diameter shaft that is gradually reduced of diameter, the internal via shape of the expansion set 2 is and ladder
The stairstepping that axis matches, the expansion set 2 are gradually reduced ladder-like in diameter from back to front.The taper platform 1-2 front end face
Diameter be less than the diameter of 2 front end inner hole 2-1 of expansion set, the diameter of taper platform 1-2 rear end face is greater than 2 front end inner hole 2-1 of expansion set
Diameter.
The working principle of the utility model is as follows: after core bar 1 is inserted into expansion set 2, gently screwing in；When just starting to screw in, core bar 1
The taper platform 1-2 front end face of front end is not with end in contact before 2 inner hole 2-1 of expansion set, and 2 front end external diameter of expansion set is less than bearing to be installed
Internal diameter, with continuing that core bar 1 is threaded into expansion set 2, before the taper platform 1-2 of 1 front end of core bar starts to press against 2 inner hole 2-1 of expansion set
End, reaches 2 front end inner hole 2-1 of expansion set using the conical surface of taper platform 1-2 and clamps bearing outward so that 2 front end of expansion set is radially expanded
3 internal diameters；By the 3 alignment bearings bore of bearing of clamping, 1 rear end of core bar is touched, the installation of bearing 3 is precisely completed.Finally, derotation core
Bar 1 is gradually backed out expansion set 2, and 2 front end of expansion set radially reduces, and exits bearing 3.Whole process is easy to operate, and clamping, tears open
It unloads convenient rapid.
