The working principle is as follows:

the core part of the set of tooling is a pressurizing unit, and the pressurizing principle is that the flange is pressurized by using continuous force generated when the spring 210 is compressed. As shown in fig. 15, the bonding pressure should be perpendicular to the curved surface, and the pressure is applied along the normal direction F0 of the curved surface (perpendicular to the tangential direction T of the curved surface), but the flange in this embodiment is T-shaped, and the positioning edge a1 of the flange needs to apply a force to attach the flange to the positioning surface, so that the direction of the force is deflected by a certain angle, which is 0 to 45 degrees, and the angle is not too large, if the angle is too large, the pressure for bonding is too small, and the pressure between the positioning edge a1 and the positioning plate is too dead, when bonding, the flange cannot move up and down, and the pressing block 211 cannot press down, thereby affecting the bonding quality, in this embodiment, the deflection angle is 30 degrees; after deflecting a certain angle, the force F on the pressure rod has component force ₁ For gluing flanges to barrels, component force F ₂ The clamping device is used for ensuring that the positioning edge of the flange is tightly attached to the positioning plate, and in addition, the force application mode, like a special-shaped cylinder, has the trend that the curved surface is from low to high, so that the pressing strip 205 can be prevented from sliding downwards along the adhesive inclined surface. Since the force pressing the positioning edge and the positioning plate is uncertain, the component force F is avoided ₂ Not necessarily enough, increase briquetting 211, utilize the elasticity degree of screwing up the nut to assist and compress tightly the locating edge.

As shown in fig. 16, before the bonding, a homemade wrench 212 having a structure similar to that of an open wrench is used to fork the hexagon 20811 of the pressure shaft 208, the pressure shaft 208 is lifted up toward the pressure plate 209, the second limit fastening point 20841 on the pressure shaft 208 passes through the lock hole 20911 of the pressure plate 209, and after the pressure shaft 208 passes through the lock hole 20911, the pressure shaft 208 is rotated, so that the second limit fastening point 20841 escapes from the opening of the lock hole 20911 and then the pressure shaft 208 can be fastened. When gluing, after the pressing strip 205 is put on, a spanner is used for pulling the pressure shaft 208, the spring 210 drives the pressure shaft 208 to pop out, so that the pressing strip 205 is pressed, the spring 210 is still in a compressed state, the compressed spring 210 can generate a certain force, the force can be transmitted to the flange by the pressure shaft 208 against the pressing strip 205, and the pressure is continuously applied even in the process of solidifying and thinning the resin adhesive.

Each positioning plate and the L-shaped foot rest 103 of the set of the tool are positioned and clamped by equal-height bolts, the structure is shown in fig. 17, the positioning plates and the L-shaped foot rest 103 ensure relative positions by using pin rod sections of the equal-height bolts, and then the positioning plates and the L-shaped foot rest are clamped by screwing nuts by using threaded sections. As shown in fig. 18, the upper positioning plate (i.e. the first positioning plate 201 and the second positioning plate 202) has 2 equal-height bolts, the equal-height bolts at the lower side corners not only serve for positioning, but also serve as the rotation axis of the upper positioning plate, and the upper side corners of the upper positioning plate are opened with a triangular opening as a handle during rotation pulling; the lower positioning plate (namely the third positioning plate 203) is provided with 4 equal-height bolts, 2 bolts play a role in positioning and clamping, the other 2 bolts serve as guide pins, longitudinal waist-shaped holes (namely guide bolt holes) are formed in the corresponding positions of the lower positioning plate, and after the 2 equal-height bolts which are positioned and clamped are pulled out, the lower positioning plate can be prevented from toppling forwards, and meanwhile, the lower positioning plate is limited to slide downwards under the action of gravity. The mode greatly facilitates operation work, during operation, only corresponding equal-height bolts need to be pulled out, the lower positioning plate can automatically slide downwards to be disengaged, the upper positioning plate also only needs to be moved open slightly forcibly, and the whole positioning plate is not required to be detached and carried.

Parameter design:

the general bonding pressure is 3-50 Psi (namely 0.0207 MPa-0.345 MPa), the contact area S =0.004m2 of the designed secondary bonding pressing bar and the workpiece is obtained according to the pressure format, and the required force applied to the pressing block is F = PS = 82.8N-1380N; if the pressure is 108N, the pressure shaft is designed at 3, the force component F1=108/3=36N and the force component angle is 30 degrees which are required to be uniformly distributed on each pressure shaft along the normal direction of the curved surface, so that according to the formula, the force generated on the pressure shaft during working is F = F1/cos30 degrees and is approximately equal to 41.57N, and the space for inserting and taking out the pressing strip is considered, so that the spring cannot be in a fully compressed state during gluing and needs to be in a semi-compressed state, the coefficient N needs to be multiplied, and the working limit load of the spring is P _j = F/n, if n is 0.5, P _j 83N, finding out the corresponding spring of 1.4 multiplied by 10 according to the standard parameter table of the cylindrical spiral compression spring, and obtaining the calculation formula suitable for the set of tool by combining the length with the space of the actually required plugging/taking pressure strip and each parameter of the compression springLength of the package.

The utility model discloses the pressurization unit can increase or reduce to splice pressure according to the actual condition of splicing, has reduced the cost that the repetition test revised the frock, has shortened the project cycle.

The above parameters are examples, many parameters can be changed, and specific parameters need to be set according to actual requirements, and the setting follows the following principle: 1. setting pressure according to the actual bonding pressure and the area of the bonding contact surface of the pressing strip; 2. the number of the pressurizing devices is reasonably arranged by considering the operation space; 3. if a manual compression spring is used, the maximum force that a person can bear needs to be considered. For example, if the force required to compress the spring is 150N, an operator needs to be able to lift 15KG of the object, so as not to exceed 100N as much as possible, and P can be reduced by increasing the length of the spring (since hooke's law F = kx, when the spring length increases, the greater the spring compressibility, the smaller the coefficient thereof, and the constant space Δ x required to plug/remove the bead, the smaller the increased force Δ F = k Δ x required to stretch the spring), or increasing the number of pressurizing devices _j ；

If the actual required glue joint pressure is larger, the space is limited, and the compression pressure of the spring is larger, so that an operator cannot pull the self-made wrench to compress the spring, a set of labor-saving clamps as shown in fig. 19 can be additionally designed for operation (the labor-saving lever principle is not described in detail).

The utility model successfully reduces the warping of the flange positioning edge and reduces the problem of inaccurate positioning through the structure that the pressing block is additionally arranged outside the oblique force application shaft; the force applying device of the tool set can increase or reduce the gluing pressure according to the actual gluing condition; increase: 1. a gasket is added on the spring and the angle steel part, so that the spring is pressed more tightly in a working state, and the pressure is increased; 2. when the spring 3 having a larger linear diameter is replaced and the pressure plate is replaced, the pressure plate deflection angle is decreased to increase the component force. And (3) reducing: 1. the spring with smaller wire diameter is replaced; 2. increasing the length of the spring; 3. and replacing the angle steel, and increasing the deflection angle of the angle steel so as to reduce the component force. The operation is carried out by a self-made wrench in a narrow space, so that the operation is simple and convenient; the mode of overturning the upper positioning plate and sliding the lower positioning plate greatly reduces the carrying burden of staff; compared with bag-making pressurization, press pressurization and tightening belt pressurization, the pressure-bonding condition can be observed more conveniently, and the pressure of each point is more variable and adjustable.

The utility model discloses not only be applicable to simple dull and stereotyped splice but also be applicable to all kinds of section of thick bamboo types, the combined material assembly of annular dysmorphism curved surface structure splices. The tool can adjust the applied pressure according to the actual condition, and can change the pressure direction by replacing part of small parts.
