Description
Technical Field
The utility model relates to the technical field of aircraft assembly process equipment, in particular to an expanding rotary pressing device.
Background
In the traditional aircraft assembly jig, the hold-down device compresses tightly the unilateral location of product part under the general circumstances, when fixing a position box-shaped assembly piece, need set up different hold-down devices respectively to both sides and bottom surface and fix a position, each hold-down device compresses tightly alone, and the operation is more loaded down with trivial details in carrying out the part assembly riveting in-process, also great simultaneously has influenced the operating space of riveting work. The traditional single compactor only comprises a working part of a seat and a pressing block, more time is required to be spent for carrying out dispersed arrangement of the compactor according to the position space of positioning installation in the assembly type frame when the tooling is designed and used, and the position needing compacting is often not provided with installation and operation space, so that the traditional dispersed compactor has larger installation limitation, operation inconvenience and positioning inaccuracy, the labor intensity of operators is increased intangibly in the mass production of the aircraft, and the working efficiency is greatly reduced.
Disclosure of Invention
The purpose of the utility model is that: an expanding rotary compression device is provided. The utility model has the characteristics of simple operation, high working efficiency and low labor intensity.
The technical scheme of the utility model is as follows: the utility model provides an rotatory closing device of expansion, includes the support, and the support bottom is connected with the end briquetting, and the support both sides all rotate and are connected with the side pressure strip, and both sides layering is "V" type structure, support top and screw rod swing joint, screw rod shaft and nut threaded connection, nut both sides are respectively through connecting rod and side pressure strip swing joint.
In the expansion type rotary pressing device, the end part of the side pressing bar is provided with the corner seat.
In the expansion type rotary pressing device, the top end of the screw rod is provided with a handle.
In the expansion type rotary pressing device, the movable connection structure of the top of the support and the screw is a ball head structure.
In the expanding rotary pressing device, the bottom of the support is provided with a notch with a fork structure, and the top of the bottom pressing block is provided with a lug structure; the connecting structure of the bottom of the support and the bottom pressing block is as follows: the lug structure at the top of the bottom pressing block is fixed through a pin shaft after being inserted into the notch at the bottom of the support.
In the expansion type rotary pressing device, the two sides of the connecting rod are notches in fork structures, and the notches on the two sides of the connecting rod are respectively meshed with the side pressing strips and the nuts and then are rotationally connected through the pin shaft.
Advantageous effects
Compared with the prior art, the utility model overcomes the defects in the prior art and provides the open type rotary pressing device; according to the structure, the pressing operation of the front edge airfoil surface on the same pressing cross section can be simultaneously realized by only one pressing device, so that the working efficiency is effectively improved, and the labor intensity is reduced; the utility model has simple operation, reduces the space requirement of the compressing device in the aspects of installation and operation, and simultaneously avoids the conditions of larger installation limitation, inconvenient operation and inaccurate positioning of the traditional distributed compressing device. Compared with the traditional point compression structure, the utility model is a surface compression structure, so that the stress of the compressed skin is more balanced.
The rotary compacting structure of the utility model promotes the shorter moving stroke of the compacting block, thus the required working space is small, the rotary compacting structure is convenient to use in occasions with smaller space, and the whole rotary compacting structure is in a V-shaped structure, and the self-locking characteristics of the screw rod and the screw rod structure are combined to promote the compacting block to stably press and avoid the defect of unbalanced pressure points.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Example 1. The utility model provides an expansion rotary pressing device, constitutes as 1-5 shows, includes support 1, and support 1 bottom is connected with end briquetting 2, and support 1 both sides all rotate and are connected with side pressure strip 3, and both sides layering 3 is "V" type structure, support 1 top and screw rod 4 swing joint, screw rod 4 shaft and nut 5 threaded connection, nut 5 both sides respectively through connecting rod 6 and side layering 3 swing joint.
The end of the side pressure strip 3 is provided with a corner seat 7.
The top end of the screw 4 is provided with a handle 8.
The movable connection structure between the top of the support 1 and the screw 4 is a ball head structure.
The bottom of the support 1 is provided with a notch with a fork structure, and the top of the bottom pressing block 2 is provided with a lug structure; the connecting structure of the bottom of the support 1 and the bottom pressing block 2 is as follows: the lug structure at the top of the bottom pressing block 2 is inserted into the notch at the bottom of the support 1 and then fixed through a pin shaft.
The two sides of the connecting rod 6 are notches in fork structure, and the notches on the two sides are respectively meshed with the side pressing bar 3 and the nut 5 and then are rotationally connected through a pin shaft.
