Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail with reference to specific embodiments and drawings.

Referring to fig. 1-2, a preferred embodiment of the present invention is as follows.

The utility model provides a bearing race pressure head, includes fixing base 1 and stopper 2, stopper 2 sets up two on fixing base 1 for the symmetry, and two stopper 2 all rotate with fixing base 1 and are connected, and two stopper 2 all with 1 elastic connection of fixing base, 1 bottom of fixing base extend have the boss 3 that is used for the storage seat circle, are equipped with the bulge 21 that is used for restricting the seat circle and drops on two stopper 2. This embodiment is when using, the seat circle is through two stoppers 2 of extrusion, make two stoppers 2 be close to each other in order to reduce the interval between the two, make the seat circle can pass two stoppers 2 and store on the boss 3 of 1 bottom of fixing base, and restrict it through bulge 21 on stopper 2 and drop, thereby realize the advance positioning of seat circle, drive the seat circle again and extrude into the bearing inner race after accomplishing in advance positioning, in order to realize the equipment of seat circle and bearing, whole bearing race pressure head withdraws from the bearing again after the equipment is accomplished. Through the mode of location in advance, store the seat circle earlier on boss 3 again, shift the seat circle again and install on the bearing, its location is accurate, can effectively avoid the slope or the skew phenomenon that the seat circle produced when extrudeing into the bearing inner race to the equipment quality of seat circle and bearing has been improved.

The fixing seat 1 comprises a connecting column 11 and two mounting blocks 12 fixed on two opposite sides of the connecting column 11, the two limiting blocks 2 are rotatably connected with the two mounting blocks 12 respectively, and the two limiting blocks 2 are elastically connected with the connecting column 11. The two mounting blocks 12 and the connecting column 11 are integrally formed, so that the connecting strength can be effectively improved.

It should be noted that there are two bosses 3, and the two bosses 3 are respectively located at the bottoms of the two mounting blocks 12. Boss 3 is semi-circular structure, and two boss 3 set up relatively, constitute the accommodation space that is used for placing the seat circle jointly, and the maximum diameter of the accommodation space that two boss 3 are constituteed is less than the diameter of seat circle to the transfer of seat circle is convenient for.

And a limiting groove 5 is arranged between the two mounting blocks 12, and the limiting block 2 is mounted in the limiting groove 5. The limiting block 2 is connected with the mounting block 12 through a screw, the limiting block 2 is provided with a mounting hole 23, and the screw penetrates through the mounting hole 23 and is fixed on the mounting block 12. The limiting groove 5 is arranged to provide a moving space for the limiting block 2, so that the limiting block 2 is not limited in rotation.

Two stopper 2 are connected with spliced pole 11 through elastic component 4, and two stopper 2 all are equipped with the recess 22 that is used for placing elastic component 4. The elastic member 4 is a metal spring or an elastic rubber, and the metal spring is preferred in the present embodiment. The one end of elastic component 4 is located recess 22, the other end and the 11 butt of spliced pole, when carrying out the prepositioning of seat circle, the seat circle is through the bulge 21 on two stoppers 2 of extrusion, makes two stopper 2 be close to each other, enters into boss 3 department through the extruded mode promptly, and the seat circle reduces the extrusion power of bulge 21 this moment, and elastic component 4 kick-backs, and bulge 21 plays the limiting displacement to the seat circle again to avoid droing of seat circle. When the race needs to be installed on the bearing inner ring, the two bulges 21 are inserted into the inner ring of the bearing, so that the bearing inner ring extrudes the two bulges 21 and simultaneously drives the race to enter the bearing inner ring until the race is fixed on the bearing inner ring in an interference manner and then retreats.

The bearing race pressure head of this embodiment still includes pilot pin 6, and pilot pin 6 and spliced pole 11 fixed connection, pilot pin 6 are located between two stopper 2. The connecting column 11 is provided with a blind hole 111, and the positioning needle 6 is inserted into the blind hole 111. The positioning pin 6 is fixed in the blind hole 111 through a bolt, or the positioning pin 6 and the blind hole 111 are in interference fit. The positioning accuracy of the seat ring in the pre-positioning and assembling process can be effectively improved by the positioning needle 6.
