Abstract

The utility model relates to a dismounting tool for a pressing bush of a solar cell array substrate. The pressing bushing dismounting tool comprises a primary dismounting tool and a secondary dismounting tool, wherein the primary dismounting tool comprises a fixed seat a, a fixed seat b, a clamping plate stop block and a screw rod a, and the secondary dismounting tool comprises a fixed seat, a stop block, a screw rod b and a nut. When the tool is detached for use at one time, the clamping plate check block is fixed between the fixed seat a and the fixed seat b and connected through the screw, and the screw a applies pressure to the compression bushing through the screw hole in the center of the clamping plate check block, so that the compression bushing is separated from the compression bushing up and down. When the secondary dismantling tool is used, the fixed seats and the stop blocks which are placed at two ends of the compression bush at the undetached side are connected through the screw rod b and the nut, the force of the stop blocks on the undetached compression bush is transmitted to the force bearing structure on the periphery of the bush by rotating the nut, and the compression bush is dismantled. The utility model adopts the screw rod structure, so that the body of the solar cell array substrate is stressed the least in the process of dismounting the upper and lower pressing bushings, and the damage risk of the substrate structure is reduced.

Description

Solar cell array substrate compresses tightly bush and demolishs frock

Technical Field

The utility model relates to the field of solar cell array substrates, in particular to a dismounting tool for a pressing bush of a solar cell array substrate.

Background

The solar cell array is a main energy source of the spacecraft, and the solar cell array substrate is a main bearing body of the cell. The solar cell array is generally designed into a folding structure so as to reduce the space occupied by the rocket system in the launching stage and unfold the rocket system after the rocket system is in orbit. The compressing and releasing mechanism folds and fixes the solar cell array on the star body in the launching stage, and releases restraint after the star body is put into orbit, wherein an upper compressing lining and a lower compressing lining are arranged in the compressing device, so that the solar cell array substrate can be correctly matched when being folded.

After the solar cell array substrate body is molded, the pressing bush is glued to the pressing point position through the rear gluing tool. The design requirement is extremely easily deviated to the precision of the position of the compressing bush after the glue joint due to the limitation of the precision of the back glue joint positioning tool and the influence of the skill level of an operator. The accuracy of the gluing position of the compression bush is an important factor for ensuring whether the compression release device can work reliably, and if the position accuracy deviates from the design requirement, the compression bush needs to be dismantled.

In the existing dismantling method, a solar cell array substrate body is generally fixed, and a special wrench and other tools are used for applying torque to a compaction lining so as to dismantle the compaction lining. The stress of the solar cell array substrate body is large in the process of dismantling, and the risk of reducing the strength of the substrate body and even damaging the substrate body exists because the strength of the substrate body is weak.

Disclosure of Invention

In order to solve the problem that the strength of a solar cell array substrate body is reduced or the body is damaged in the process of disassembling a pressing bush, the utility model provides a disassembling tool for the pressing bush of the solar cell array substrate.

A solar cell array substrate pressing bushing dismounting tool comprises a primary dismounting tool and a secondary dismounting tool; the primary dismantling tool comprises a fixed seat a, a fixed seat b, a clamping plate stop block and a screw rod a, and the secondary dismantling tool comprises a fixed seat, a stop block, a screw rod b and a nut; the cardboard dog is fixed in the middle of fixing base and fixing base, passes through screw rod b and nut with fixing base and dog and is connected.

The middle part of the clamping plate check block which is detached once is provided with an internal thread consistent with the screw rod a, and the clamping plate check block is connected with the screw rod b through a nut.

The clamping plate check block square boss structure of the one-time dismounting tool is connected with the square groove structures of the fixed seat a and the fixed seat b.

And the screw and nut connecting structure of the secondary dismantling tool enables the fixed seat and the stop block to be stressed, so that the compression bushing is dismantled.

The diameter of the inner groove of the fixture fixing seat is larger than the outer diameter of the pressing bush by 4mm, and smooth removal of the pressing bush is guaranteed.

The utility model has the following functions and effects:

the pressing bushing dismounting mode adopting the technical scheme is simple and rapid when the pressing bushing is dismounted, damage to the solar cell array substrate in the dismounting process is avoided, and the pressing bushing dismounting tool is simple in structure, convenient to manufacture and low in cost.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the following embodiment is used to specifically describe the dismantling tool for the solar cell array substrate pressing bushing of the utility model with reference to the attached drawings. It is to be understood that the described embodiments are merely exemplary of a portion of the utility model and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment is described with reference to fig. 1 and 3, and the one-time removal tool includes a fixed seat a101, a fixed seat b102, a clamping plate stopper 103, and a screw rod a 104. When once demolising the frock and using, the annular boss that will compress tightly the bush is placed in the annular groove of fixing base a101, put into the square groove of fixing base b102 with the square boss of cardboard dog 103, fixing base a101 is placed the one side of fixing base b102 symmetry, use two M4 screws to connect fixing base a101 fixing base b102, again with M16 screw rod a104 screw in the M16 threaded hole of cardboard dog 103, through rotating screw rod a104, produce the pressure of interact between the bush from top to bottom compressing tightly, thereby demolish the bush that compresses tightly that the bonding strength is more weak one side.

Referring to fig. 2 and 4, the secondary dismantling tool includes a fixing base 201, a stopper 202, a screw b203, and a nut 204. When the tool is dismounted for the second time, the fixed seat 201 is placed on the surface of the compression bushing on the side which is not dismounted, the stop block 202 is placed in the inner hole of the compression bushing on the side which is dismounted, the fixed seat 201 and the stop block 202 are connected by using the screw rod b203 and the nut 204, and the stop block 202 generates pressure on the compression bushing by rotating the nut 204, so that the compression bushing on the other side which is not dismounted by the tool is dismounted.

Action and effect of the examples:

according to the solar cell array substrate pressing bushing dismantling tool, the risk of damage to the solar cell array substrate in the dismantling process is avoided, and the pressing bushing dismantling tool is simple in structure, convenient to manufacture and low in cost.

When the tool is detached for use at one time, the upper pressing bushing and the lower pressing bushing are mutually acting points, only the bearing structure at the periphery of the bushing of the solar cell array substrate bears the shearing force of the bonding glue in the detaching process of the pressing bushing, and the body of the pressing bushing is free from the action of the stress. When the secondary dismantling tool is used, the bearing structure on the periphery of the lining serves as an acting point, only the bearing structure on the periphery of the lining bears the pressure of the fixing seat in the dismantling process, and the solar cell array substrate body is free from the action of stress.
