Abstract

A steel ball splitting device of a deep groove ball bearing comprises an air cylinder (5), a positioning clamp (2) and a ball splitting punch (1), wherein the ball splitting punch (1) is fixed on a piston rod of the air cylinder (5), plugging rods (11) which are respectively in a sharp shape and have same quantity with balls are fixed on the ball splitting punch, the plugging rods (11) are distributed in an annular matrix way, the positioning clamp (2) is provided with a lug boss (22) and an outer ring accommodating nest (21), and a retainer ring (23) is fixed inside the outer ring accommodating nest (21). Due to the adoption of the steel ball splitting device, the production efficiency is improved, the device can be conveniently applied to the production line, and the automatic assembling of the bearing can be realized.

Description

Deep groove ball bearing steel ball equipartition device

Technical field:

The utility model relates to bearing assembly machine tool technical field, more specifically to a kind of deep groove ball bearing steel ball equipartition device.

Background technique:

Before deep groove ball bearing steel ball fixing frame is installed, need make ball be evenly distributed between inner ring and the outer ring, be to lean on operation manually a bit when now ball being divided equally; Some is to divide equally anchor clamps through bearing; Inner ring and the space between the outer ring with bearing is divided into some five equilibriums earlier, then ball put into corresponding the inside, space, and the mode of dividing equally of these balls makes manufacturing efficiency low; And complex operation, be not easy to realize the automatic assembling of bearing machinery.

The model utility content:

The purpose of the utility model is exactly the deficiency to existing technology; And a kind of deep groove ball bearing steel ball equipartition device is provided; It can be divided equally ball through inserted link simply, has improved the efficient of producing, and can realize bearing automation assembling very easily.

The technological solution of the utility model is following:

Deep groove ball bearing steel ball equipartition device; Comprise that cylinder, positioning fixture and ball divide equally drift; Ball is divided equally on the piston rod that drift is fixed on cylinder, and ball is divided equally and is fixed with the inserted link that is tip shape and equates with ball quantity on the drift, and said inserted link circular array distributes; Positioning fixture forms boss and nest is accommodated in the outer ring, and back-up ring is fixed on the outer ring and accommodates in the nest.

Said back-up ring is weldingly fixed on the outer ring and accommodates in the nest.

The said ball that stretches out is divided equally two the longest inserted links symmetrical distributions of drift, and remaining inserted link is arranged by the length of stretching out drift from high to low from left to right.

The beneficial effect of the utility model is:

1, it is divided equally through the ball that the inserted link action once just can will be distributed between bearing inner race and the outer ring, has improved the efficient of producing.

2, its total and operation are all very simple, can easily it be applied in the automatic production, realize the automation assembling of bearing.

Description of drawings:

Fig. 1 is the structural representation of the utility model

Fig. 2 is all structural representations of parted hair of ball

Fig. 3 is the structural representation of positioning fixture

Among the figure: 1, ball is divided equally drift; 2, positioning fixture; 3, bearing outer ring; 4, bearing inner race; 5, cylinder; 11, inserted link; 21, nest is accommodated in the outer ring; 22, boss; 23, back-up ring.

Embodiment:

Embodiment: see shown in Fig. 1 to 3; Deep groove ball bearing steel ball equipartition device comprises that cylinder 5, positioning fixture 2 and ball divide equally drift 1, and ball is divided equally on the piston rod that drift 1 is fixed on cylinder 5; Ball is divided equally and is fixed with the inserted link 11 that is tip shape and equates with ball quantity on the drift 1; Said inserted link 11 circular array distribute, and positioning fixture 2 forms boss 22 and accommodates nest 21 with the outer ring, and back-up ring 23 is fixed on the outer ring and accommodates in the nest 21.

Said back-up ring 23 is weldingly fixed on the outer ring and accommodates in the nest 21.

The said ball that stretches out is divided equally two the longest inserted links of drift 1 11 and is symmetrically distributed, remaining inserted link by 11 stretch out drift length arrange from left to right from high to low.

Working principle: bearing inner race 4 sleeves are on boss; Bearing outer ring 3 places the outer ring to accommodate nest 21; And the bottom of bearing outer ring 3 is shelved on the back-up ring 23; Because the thickness of back-up ring 23 is thicker a little compared with bearing outer ring 3, so back-up ring 23 has also blocked ball between bearing outer ring 3 and bearing inner race 4 and the space that between bearing inner race 4 and bearing outer ring 3, supplies inserted link 11 to pass in addition when blocking bearing outer ring 3.

Cylinder 5 drive balls are divided equally drift 1 and are moved downward; Being fixed on ball, to divide equally the head of the inserted link 11 on the drift 1 are tip shapes, and inserted link 11 uneven ground circular array distribute, when ball is divided equally drift 1 and moved downward; At first be to stretch out ball to divide equally two the longest inserted links of drift 1 11 and get between the balls; With the ball separated into two parts, then second long two inserted links 11 inject between the ball, along with ball is divided equally moving downward of drift 1; Inject between the ball until two the shortest inserted links 11, so just realized dividing equally each ball.

Claims

1. deep groove ball bearing steel ball equipartition device; Comprise that cylinder (5), positioning fixture (2) and ball divide equally drift (1); Ball is divided equally drift (1) and is fixed on the piston rod of cylinder (5), it is characterized in that: ball is divided equally and is fixed with the inserted link (11) that is tip shape and equates with ball quantity on the drift (1), and said inserted link (11) circular array distributes; Positioning fixture (2) forms boss (22) and nest (21) is accommodated in the outer ring, and back-up ring (23) is fixed on the outer ring and accommodates in the nest (21).

2. deep groove ball bearing steel ball equipartition device according to claim 1 is characterized in that: back-up ring (23) is weldingly fixed on the outer ring and accommodates in the nest (21).
