Description

Flexible door structure of steel cable joint spinning forming machine

Technical Field

The utility model belongs to cable wire connects spinning technique relates to a flexible door structure of cable wire connects spinning forming machine.

Background

A spinning forming machine (s10) for a steel cable joint is special aviation equipment for aviation manufacturers, the steel cable joint and a steel cable of a navigation mark are assembled, the requirements of standards such as HB5-11, HB5-16, HB5-17, HB5-18 and HB7387.8 are met, the equipment often has the defects of ultra-poor part size and unstable surface quality in the use process, a safety door copper sleeve is seriously worn, the structure of the equipment door is unreasonable, the structural composition of the equipment is analyzed, a rotating main shaft rotates at a high speed in the working process, the door not only needs to realize a pressing function, but also needs to realize follow-up to reduce the serious wear caused by hard contact.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the utility model provides a flexible door structure of steel cable joint spinning forming machine avoids leading to the longer phenomenon of down time of equipment because of changing the vulnerable part repeatedly.

The technical scheme of the utility model is that:

in a first aspect, a flexible door structure of a steel cable joint spinning forming machine is provided, which includes: the structure comprises an end cover 1, a positioning piece 3, an elastic retainer ring 4, a deep groove ball bearing 5 and a door main body 6 with a step shaft structure;

deep groove ball 5 installs behind the hole of setting element 3, and deep groove ball 5 installs on the step of 6 of door main part together with setting element 3, and circlip 4 installs in the slot on the step, and end cover 1 links into an organic whole with setting element 3.

Further, the structure further comprises: fixing a flexible door structure of a steel cable joint spinning forming machine on a door lug 7 on equipment; the door lug 7 is fixed to the edge of the door main body 6.

Furthermore, the fixing mode of the door handle 7 is welding.

Further, the structure further comprises: the end cover 1 is provided with a through hole which is perpendicular to the axial direction of the end cover and corresponds to the cross recessed countersunk head screw 2, and the cross recessed countersunk head screw extends into the through hole to connect the end cover 1 and the positioning part 3 into a whole.

Furthermore, the number of the cross recessed countersunk head screws is 8, and the cross recessed countersunk head screws are uniformly distributed on the end surface of the end cover 1.

Further, the deep groove ball bearing 5 comprises an inner ring, an outer ring and a circle of balls arranged between the inner ring and the outer ring;

the inner ring is fixed on the step of the door body 6, and the outer ring is fixedly connected with the positioning piece 3; when the outer ring is subjected to the external friction force of the end cover 1, the balls drive the outer ring to rotate.

The utility model has the advantages that:

the utility model discloses at cable wire joint spinning in-process, when the mould operates at a high speed, the partial structure of door is rotatory along with the mould, greatly reduced the wear rate of end cover, play the effect that compresses tightly to the mould simultaneously, make the mould can not the axial float, the purpose of protection is played in the flexible laminating, and avoids leading to the longer phenomenon of down time of equipment because of changing the vulnerable part repeatedly.

Drawings

FIG. 1 is a side view of a flexible door structure of a spinning forming machine for wire rope joints according to an embodiment of the present invention;

fig. 2 is a front view of a flexible door structure of a spinning forming machine for steel cable joints according to an embodiment of the present invention.

Detailed Description

The present invention will be described in further detail below.

The utility model discloses reform transform original cable wire joint spinning make-up machine door structure, as shown in fig. 1, provide a flexible door structure of cable wire joint spinning make-up machine

The novel door mainly comprises an end cover 1, a cross recessed countersunk head screw 2, a positioning piece 3, an elastic retainer ring 4, a deep groove ball bearing 5, a door main body 6 and a door lug 7. The door structure is characterized by comprising a deep groove ball bearing 5, wherein a bearing inner ring is arranged on a shaft outer ring of a door main body 6, the right end surface of the bearing inner ring abuts against the step surface of the door main body, and an elastic retainer ring 4 is arranged in a shaft groove of the door main body to limit the axial movement of the bearing inner ring; the positioning piece 3 is arranged on the outer ring of the bearing 5, the right end face of the outer ring of the bearing abuts against the step face of the positioning piece, the end cover 1 and the positioning piece 3 are connected into an integral structure through the cross-shaped groove countersunk head screw 2, and the right end face of the end cover 1 presses the outer ring of the bearing tightly to prevent the outer ring of the bearing from moving axially.

The elastic retainer ring 4 arranged in the groove at the shaft end of the door main body 6 limits the left and right movement of the inner ring of the deep groove ball bearing 5, and the positioning piece 3 and the end cover 1 limit the left and right movement of the outer ring of the deep groove ball bearing 5.

As shown in fig. 2, the working principle of the present invention is: in operation, the door body 6 is closed and the door lug 7 is secured so that the door body 6 cannot be opened. The equipment mould is attached to the end cover 1. When the equipment mould rotates, the equipment mould and the end cover 1 generate friction force, and the positioning piece 3 and the end cover 1 are driven to rotate together with the mould through the rotation of the balls of the deep groove ball bearing 5. Therefore, the abrasion speed of the end cover is reduced, and the die is compressed, so that the die cannot axially move.
