Abstract
The utility model belongs to the field of machine design, and particularly relates to a bearing axial positioning necking fixing tool. The bearing axial positioning and necking fixing tool is used for taking the place of a traditional rolling wheel necking and pressing mode, and is a necking and pressing tool capable of being controlled in a quantified mode. The bearing axial positioning and necking fixing tool is of the structure of a solid of revolution; a positioning hole is formed in the middle of the bearing axial positioning necking fixing tool; a plane close to the positioning hole can avoid the situation that the end surface of an inner ring of a bearing intervenes in the bearing axial positioning and necking fixing tool; sharp necking and pressing corners are arranged at the bottom of the bearing axial positioning and necking fixing tool. Through necking and pressing amount control, the bearing axial positioning necking fixing tool ensures that bearings bear enough axial push force after being converged and pressed, axial clearance or starting force moment does not change obviously, certain flexibility of the bearings is kept, the bearings are quickly fixed, and 100% qualification rate of the bearings is achieved.
Description
Technical field
The utility model belongs to mechanical design field, particularly relates to a kind of bearing axial location closing in setting tool, for substituting traditional roller, receives the pressure mode, is a kind of receipts press tool that can quantize control.
Background technology
Airplane parts is when installing bearing, traditional roller is received impacts such as pressing the size of can not quantified controlling receiving pressure and rotating speed and is received the factor of pressing effect, rely on operator's working experience fully, what the bearing after installation can not guarantee axially to release power, end-play or staring torque etc. simultaneously all meets designing requirement, causes scrapping of part and bearing.
Summary of the invention
The purpose of this utility model is: a kind of setting tool of bearing is provided, and after guaranteeing that the bearing receipts have been pressed, when bearing enough axial release power, the end-play of bearing or staring torque significantly do not change, and keep certain rotation flexibility.
The technical solution of the utility model is: a kind of bearing axial location closing in setting tool, for rotary structure, centre is provided with locating hole 1, near the plane of locating hole 1, avoid bearing inner race end face and bearing axial location closing in setting tool to interfere, bottom arranges receives pointing angle 2, receive 2 positions, pointing angle consistent with bearing mounting groove 3 or the bearing block counter boring 4 of bearing outer ring, receipts pointing angle 2 is mainly used in the receipts pressure limit of bearing outer ring mounting groove 3 or bearing block counter boring 4, the internal diameter of locating hole 1 is consistent with bearing bore diameter, the plane of receiving 2 outsides, pointing angle is locating surface 7, for limiting the pressure amount of receiving, receive the size of pressure amount, according to the size of bearing outer ring mounting groove 3 or bearing block counter boring 4, determine.
When the receipts last item holds mounting groove 3, the inner face angle β that receives pointing angle 2 is less than 30 ° of bearing outer ring mounting groove 3 inner face angles, and bearing outside angle α is greater than 30 ° of bearing outer ring mounting groove 3 outside angles.
When receiving last item bearing counter boring 4, the inner face angle β that receives pointing angle 2 is greater than 30 ° of bearing block counter boring 4 inner face angles, and the outside angle α that receives pointing angle 2 is less than 30 ° of bearing block counter boring 4 outside angles.
The utility model has the advantages that: the utility model bearing axial location closing in setting tool is received the pressure amount by control, after guaranteeing that the bearing receipts have been pressed, when bearing enough axial release power, the end-play of bearing or staring torque significantly do not change, keep certain rotation flexibility, realize the qualification rate of the quick fixing of bearing and 100%.

The specific embodiment
Below the utility model is described in further details, refers to Fig. 1 to Fig. 5.
As shown in Figure 1, receive the structural representation of pressing for traditional roller.Before receiving pressure processing, roller is received to press tool to be arranged on drilling machine, bearing is installed in bearing block, utilize bearing that bearing and bearing block support are placed on the drilling machine stand, receive the locating shaft on press tool by roller, regulate bearing and bearing block and roller and receive press tool centering, then, regulate roller by the rocking arm of drilling machine and receive press tool and bearing and the bearing block distance in the drill press spindle direction.Adjust suitable after, start drilling machine, apply receipts pressure by rocking arm, realize the flange of bearing outer ring mounting groove or bearing block counter boring by the rotation of drill press spindle, realize that bearing closes up fixing.The rotary speed of receiving the size of pressure and drill press spindle is to affect the bearing fixing key that closes up, and human factor is more, is unfavorable for quantified controlling.
As shown in Figures 2 and 4, bearing axial location closing in setting tool is rotary structure, it is characterized in that, centre is provided with locating hole 1, near the plane of locating hole 1, avoid bearing inner race end face and bearing axial location closing in setting tool to interfere, bottom arranges receives pointing angle 2, receive 2 positions, pointing angle consistent with bearing mounting groove 3 or the bearing block counter boring 4 of bearing outer ring, receipts pointing angle 2 is mainly used in the receipts pressure limit of bearing outer ring mounting groove 3 or bearing block counter boring 4, the internal diameter of locating hole 1 is consistent with bearing bore diameter, the plane of receiving 2 outsides, pointing angle is locating surface 7, for limiting the pressure amount of receiving, receive the size of pressure amount, according to the size of bearing outer ring mounting groove 3 or bearing block counter boring 4, determine.
As shown in Figures 2 and 3, when the receipts last item holds mounting groove 3, the inner face angle β that receives pointing angle 2 is less than 30 ° of bearing outer ring mounting groove 3 inner face angles, and bearing outside angle α is greater than 30 ° of bearing outer ring mounting groove 3 outside angles.
As shown in Figures 4 and 5, when receiving last item bearing counter boring 4, the inner face angle β that receives pointing angle 2 is greater than 30 ° of bearing block counter boring 4 inner face angles, and the outside angle α that receives pointing angle 2 is less than 30 ° of bearing block counter boring 4 outside angles.
