Description
Technical Field
The utility model relates to a bearing bush installation location auxiliary device.
Background
The bearing bush is a part of precision supporting shafts in mechanical equipment, a bearing is a rolling bearing, the bearing bush and a shaft are sliding bearings, one set of the bearing bush generally adopts a three-piece sheet structure, namely, the circumference of the shaft sleeve is equally divided into a plurality of pieces, the aperture of the bearing bush of some mechanical equipment is smaller and longer, the diameter of a circle formed by correspondingly matched sheet bearing bushes is smaller, the single-piece bearing bush is also longer, in actual installation, the three-piece sheet bearing bush needs to be installed and fixed in an equal division mode in a bearing bush hole of the mechanical equipment, however, the bearing bush hole with a small aperture directly influences visual difficulty and hand difficulty in extending into the bearing bush hole for auxiliary installation when the bearing bush is installed, and is also difficult to perform equal division positioning installation.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, an object of the utility model is to provide a bearing bush installation location auxiliary device, the location core one end of location axle is established the connecting axle and is cup jointed the back with axial separation blade and connecting axle and lock with the nut, a plurality of constant head tanks of outer circumference equipartition of location core, and the width of constant head tank is not more than 0.1mm with flaky axle bush width clearance, and the degree of depth is greater than flaky axle bush thickness and is not less than 5mm, the utility model discloses angle location that can be accurate and install flaky axle bush, greatly reduced the downthehole location degree of difficulty and the installation accuracy of installing longer flaky axle bush of long and slender axle bush.
In order to achieve the above purpose, the technical scheme of the utility model is that: a bearing bush mounting and positioning auxiliary device comprises a positioning shaft, wherein a connecting shaft is arranged at one end of a positioning core of the positioning shaft, an external thread is arranged on the outer side of the connecting shaft, a knurled handle is arranged on the outer side of the external thread, and a nut is in threaded connection with the external thread after an axial blocking piece is sleeved with the connecting shaft;
and a plurality of positioning grooves are uniformly distributed on the outer circumference of the positioning core.
Further setting, the width of constant head tank is not more than 0.1mm with flaky axle bush width clearance.
Further, the depth of the positioning groove is larger than the thickness of the flaky bearing bush and is not smaller than 5 mm.
The utility model has the advantages that: the utility model discloses angular positioning that can be accurate and installation flaky axle bush, greatly reduced the downthehole location degree of difficulty and the installation accuracy of installing longer flaky axle bush of long and thin axle bush.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a left side view of fig. 1.
In the figure: the positioning device comprises a positioning shaft 1, a positioning core 11, a connecting shaft 12, external threads 13, a knurled handle 14, an axial blocking piece 2, a nut 3 and a positioning groove 4.
The specific embodiments,
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
As shown in fig. 1-2, in the bearing bush mounting and positioning auxiliary device, a connecting shaft 12 is arranged at one end of a positioning core 11 of a positioning shaft 1, an external thread 13 is arranged on the outer side of the connecting shaft 12, a knurled handle 14 is arranged on the outer side of the external thread 13, and a nut 3 is in threaded connection with the external thread 13 after an axial blocking piece 2 is sleeved with the connecting shaft 12; a plurality of constant head tanks 4 of outer circumference equipartition of location core 11, the utility model discloses the angle location that can be accurate and install flaky axle bush, greatly reduced the downthehole location degree of difficulty and the installation accuracy of installing longer flaky axle bush of long and thin axle bush.
The width of the positioning groove 4 and the width clearance of the flaky bearing bush are not more than 0.1mm, and the circumferential error is enlarged due to deviation of the monolithic bearing bush to the maximum extent.
The depth of the positioning groove 4 is larger than the thickness of the flaky bearing bush by not less than 5mm, so that the collision and abrasion of the outer circumference of the single bearing bush are avoided, and the fixation of the single bearing bush with a bearing bush hole of mechanical equipment after being pulled up by a mounting screw is not influenced.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. The skilled person in this trade also understands, the utility model discloses do not receive the restriction of above-mentioned embodiment, the description only is the explanation in above-mentioned embodiment and the description the principle of the utility model, do not keeping away from the utility model discloses under the connection meter category prerequisite, the utility model discloses still can have various changes and improvement, these changes and improvement all fall into the protection of the utility model discloses the within range. The scope of the invention is defined by the appended claims and equivalents thereof.
