The tool comprises a channel steel seat, a pressing block, a support column, a tightening rod, a pressing plate and a thread bushing; the torque wrench is screwed down according to the pressing force required by the process, so that the labor intensity of an operator is reduced. Simple structure, safety and reliability, and is beneficial to popularization.
Description
Technical Field
The utility model belongs to the technical field of rocket projectile or the relevant manufacturing of nozzle seat, a frock that is used for nozzle body and graphite layer to keep compressing tightly is related to.
Background
The nozzle holder consists of a nozzle body and a graphite layer, wherein the nozzle body and the graphite layer are in compression joint in a gluing mode (see figure 1). In the manufacturing process, the body and the graphite are firstly bonded together by strong glue, then are pressed by a press with the force of 120N and are kept for 48 hours, or are pressed by a steel block (lead pouring) with the equivalent force of 120N, and finally are machined subsequently.
The nozzle base structure is as the above figure: 11 graphite layers and 12 nozzle bodies.
The disadvantages of using the two compression methods described above: when the nozzle base is pressed by a press machine, the production schedule is severely restricted due to large batch of products, large quantity of products and limited pressure equipment. When the steel block (filled with lead) is used for compaction, the steel block is heavy due to overlarge volume and frequent use, and the labor intensity of workers is increased; meanwhile, the manufacturing cost is increased, and the lead-filled steel block is easy to cause environmental pollution.
Therefore, the novel tool can be designed and manufactured, the requirement for keeping the pressing force is met, the labor intensity of an operator is reduced, the manufacturing cost is reduced, and the environmental pollution is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a frock for nozzle holder keeps compressing tightly for certain product nozzle holder keeps compressing tightly's frock, what solve is that nozzle holder keeps the technical problem of packing force, and uses the frock to reduce manufacturing cost and reduce operator's intensity of labour. And designing and manufacturing a tool aiming at the requirements of the compression and pressure maintaining time of the spray pipe body and the graphite, and the tool is used for processing the spray pipe seat.
The technical scheme of the utility model is that: a tool for keeping a nozzle seat compact is characterized by comprising a channel steel seat, a pressing block, a support column, a tightening rod, a pressing plate and a thread bushing; the two pillars are screwed at the two ends of the channel steel seat; the pressing plate is placed on the two supporting columns and is screwed tightly by nuts respectively; the thread bushing and the tightening rod are screw nut pairs, and the periphery of the thread bushing is fixedly connected with the pressing plate; the lower end of the tightening rod is connected with a pressing block; the pressing block is pressed in the nozzle seat; the upper end of the tightening rod is hexagonal.
Furthermore, the screw rod and the threaded bushing are connected through trapezoidal threads and are axially compressed.
Furthermore, still include the rubber pad, be located nozzle base lower extreme, and be located the channel steel seat.
Further, the number of the pressing plates is one; the thread bushing, the tightening rod and the pressing block are combined into a plurality of combinations and are connected with a pressing plate, and each combination is used in a nozzle seat.
Furthermore, the combination of the pressing block, the threaded bushing and the tightening rod is 5.
The technical effects of the utility model are that:
1. reduce environmental pollution and manufacturing cost
The graphite layer is compressed by the compression tool, a compression mode (or a compression mode by a press) of the lead-filled steel block is replaced, the environmental pollution can be reduced, and the manufacturing cost is reduced.
2. Reduce the labor intensity of operators
As the pressing tool only needs to place the nozzle base on the channel steel base and is screwed down by the torque wrench according to the pressing force required by the process, the labor intensity of an operator is reduced. Therefore, the tool has the advantages that: simple structure, safety and reliability, and is beneficial to popularization.
