Detailed Description

The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.

As shown in the figure, this worm is pressure equipment frock for bearing includes:

the fixing seat 10 comprises a lower base 11 and an upper clamping seat 12, the lower base 11 and the upper clamping seat 12 are arranged in parallel, a placing groove 111 is formed in the base 11, the placing groove 111 is used for placing a first bearing 30, a U-shaped clamping groove 121 is formed in the free end of the upper clamping seat 12, and the U-shaped clamping groove 121 is used for placing and extending out of a worm;

the pressure bar 20 is provided with an inner hole 21 on the pressure bar 20, the inner hole 21 is used for placing a central rod of the worm, the diameter of the inner hole 21 is a, the diameter of the central rod of the worm is b, and the size relationship is satisfied: a-b.

The utility model discloses guaranteed the reasonable of in-process bearing stress surface of impressing and the straightness that hangs down of worm and bearing, greatly reduced the defective rate that the pressure equipment in-process produced to production efficiency has been promoted.

In this embodiment, the specific operation is divided into the following three steps

Step one, the positioning and placement of the bearing I30 are realized through the fixed seat 10

Firstly, the first bearing 30 is placed in the placing groove 111 of the fixed base, and the placing groove 111 is matched with the first bearing 30 in shape, so that the operation is convenient and quick;

step two, the worm 40 is placed through the fixing seat 10

A worm 40 is clamped into the U-shaped groove, and one end of the worm 40 is aligned to the circle center of the first bearing 30;

step three, fixing the second bearing 50 with the top of the worm 40

And after the positioning in the second step is finished, the top of the worm 40 is sleeved into the second bearing 50, and finally the pressure rod 20 is pressed down.

In the above operation process, since the bearing support hole is a horizontal plane, the maximum outer diameter of the pressure rod 20 is smaller than the outer diameter of the bearing, and the bearing surfaces are inner rings of the bearing.

As a further preferred embodiment, the strut 20 comprises a fixing portion 22 and an abutment portion 23, the diameter of the fixing portion 22 being greater than the diameter of the abutment portion 23.

The diameter of the fixing portion 22 is larger than that of the abutting portion 23, so that the press can be conveniently clamped in specific operation, and the second bearing 50 can be conveniently pressed into the central rod of the worm.

As a further preferred embodiment, the maximum outer diameter of the abutment 23 is smaller than the outer diameter of the second bearing 50.

The maximum outer diameter of the abutting part 23 is smaller than that of the bearing II 50, so that the bearing surfaces are bearing inner rings when the bearing II 50 is pressed in.

As a further preferred embodiment, the two ends of the placing groove 111 are symmetrically provided with a first through groove 112 and a second through groove 113.

Through the first through groove 112 and the second through groove 113 symmetrically arranged at the two ends of the placing groove 111, the bearing first 30 can be conveniently placed into the placing groove 111 matched with the shape of the bearing by manpower during specific operation, and positioning is also facilitated; and the placement and the removal of the bearing-one 30 are also convenient.

As a further preferred embodiment, the inner wall of the U-shaped slot 121 is symmetrically provided with worm positioning devices.

During specific operation, the U-shaped slot 121 is used for placing the worm 40, and when the bearing two 50 is pressed into the upper end of the worm 40, if the worm positioning device is not arranged, the worm 40 may shake in the U-shaped slot 121 and cannot be positioned, which is not favorable for assembling the bearing two 50 and the worm 40.

As a further preferred embodiment, the worm positioning means is a ball 122.

In the embodiment, the worm 40 is effectively positioned by the arrangement of the worm positioning device, namely the arrangement of the marble 122; moreover, the ball 122 is in a spherical shape, and the contact between the outer surface of the worm 40 and the ball 122 is point contact, so that the friction or abrasion caused by the contact is further reduced, and the use is convenient.

The press-fitting tool for the worm bearing is reasonable in structural design, and the worm 40, the first bearing 30 and the second bearing 50 are effectively assembled through the fixed seat 10 and the pressure lever 20; because the bearing support hole is a horizontal plane, the maximum outer diameter of the pressure lever 20 is smaller than the outer diameter of the bearing, and the stress surfaces are all inner rings of the bearing, the bearing cannot be damaged; the condition that the bearing and the worm are not vertical is avoided, and finally, the assembled product cannot generate abnormal sound; the product percent of pass and the production efficiency are improved.

The preferred embodiments of the present invention are described herein, but the scope of the present invention is not limited thereto. Modifications or additions to or replacement by similar means to those skilled in the art to which the invention pertains to the specific embodiments described herein are intended to be covered by the scope of the invention.
