T-profile assembly tool

Abstract

The invention provides a T-profile assembly tool. The tool comprises a bottom frame and a face plate jig, a web plate jig and a lifting unit which are arranged on the bottom frame. A face plate bearing face which is inclined to be used for bearing a T-profile face plate is arranged on the face plate jig. A web plate bearing face which is inclined to be used for bearing a T-profile web plate is arranged on the web plate jig. The web plate bearing face is vertical to the face plate bearing face and form a T shape with the face plate bearing face. A gap for the T-profile to penetrate is formed between the end of the web plate bearing face and the face plate bearing face. The lifting unit is arranged corresponding to the face plate jig to be used for supporting the lower end of the T-profile face plate. The upper end height of the lifting unit is adjustable, and accordingly, the distance from the lower end of the T-profile face plate to the web plate bearing face is adjusted. The tool is convenient to operate, accurate in location, high in assembly efficiency and capable of improving the T-profile assembly quality, reducing the worker labor intensity and saving labor hours.

Description

technical field [0001] The invention relates to tooling equipment, in particular to a T-shaped bar assembly tooling. Background technique [0002] There are many specifications of marine T profiles, and there is no standard size. Therefore, steel plates are cut and welded in various shipyards. The traditional T-profile prefabrication process is as follows: first draw a line on the T-profile panel, then lay the T-profile panel on the ground, and then hoist the T-profile web to the panel for positioning. Since the T-profile web is usually relatively high, therefore In addition to spot welding positioning, some temporary braces are also welded. This method has the following disadvantages: [0003] 1) Positioning is difficult, because it needs to be hoisted by a crane to align with the theoretical line on the T-profile panel, which requires long-term adjustment. [0004] 2) There are security risks. In order to reduce the time for positioning, workers usually need people to ...

AI Technical Summary

Problems solved by technology

[0003] 1) Positioning is more difficult, because it needs to be hoisted by a crane to align with the theoretical line on the T-profile panel, which requires long-term adjustment

[0004] 2) There are potential safety hazards

In order to reduce the time for positioning, workers usually need people to assist in adjusting the T-shaped profile, which poses safety hazards to workers

[0005] 3) Low welding efficiency

[0006] 4) The welding quality is unreliable, and the probability of repair is relatively high

Welding quality depends entirely on the experience of the workers, and welders have high mobility, so the welding quality is very unstable

[0007] 5) Damage to the base material

Because temporary supports need to be welded, when these supports are cut off, there will be different degrees of damage to the positions that do not have solder joints

[0008] 6) The operating environment of the workers is poor, and there is a certain degree of personal injury to the welders

This kind of fully armed labor insurance, in the hot summer, welders are at risk of heat stroke

[0009] 7) Usually, the two-point clamping method is used to hoist the T-shaped web, and the T-shaped web is easy to cause local deformation due to its relatively large width.

In the harsh operating environment on site, this device is easily deformed, which reduces the operating accuracy

[0014] 3) There is a gap between the adjustment arm and the T-shaped web, so other devices have to be used for adjustment, which increases the complexity of its operation

[0015] 4) There is no adjustment device for the T-profile panel on the bottom plate, and manual adjustment of the position of the panel is still required, which increases the adjustment time

[0016] 5) There is no fixed position of the T-profile panel on the bottom plate, and when installing the T-profile web, it may cause the position of the T-profile panel to change, so it has to be adjusted again

[0018] 1) There is a great restriction on the height of the web of the T profile

Since the distance between the formwork and the base plate is fixed, if the height of the T-shaped web exceeds the distance between the formwork and the base plate, it cannot be used; if the distance between the T-shaped web and the formwork is too large, the iron wedge cannot be connected with the T-shaped web, and cannot use

[0019] 2) Since the template is cut from steel plates, when the height is relatively large, it is easy to bend under the harsh operating environment on site

[0020] 3) Since there are only two fixed templates, when the length of the T profile is less than the distance between the two templates, it cannot be used; when the length of the T profile is much larger than the distance between the two templates, the parts that grow at both ends are prone to deformation , so that the accuracy of the equipment cannot be guaranteed

[0021] 4) Since the panel and web of the T profile are adjusted by iron wedges, multiple sets of iron wedges are required for many specifications of T profiles on board, thus increasing manufacturing costs and management costs

[0022] 5) Since multiple sets of iron wedges and devices are not fixed, the iron wedges are easily lost in shipyards with a very large flow of personnel on site

[0023] 6) Since the panel and web of the T profile are adjusted with iron wedges, the assembly time is lengthened and the work efficiency is affected

[0024] 7) Since only one side of the web of the T-shaped bar has a limited position, the clamp of the crane can only be loosened when the iron wedge with the web is installed. The hoisting and personnel operation are mixed together, which increases the safety hazard

[0026] 1) This kind of device is too complicated and the manufacturing cost is too high

[0027] 2) When the electromagnetic chuck absorbs the web and stands up, the electromagnetic chuck has no lifting capacity at all, and it is impossible to hoist it to the T-shaped panel

Therefore, other hoisting equipment is still required to operate in this process, which greatly reduces work efficiency

[0028] 3) Only T-profiles with symmetrical panels can be assembled, and it cannot be operated for eccentric T-profiles

[0029] 4) This invention is welded on the rear side of the gantry bracket, and the two cannot achieve the same speed, so only one section can be aligned and one section welded, and the continuous welding of the weld cannot be realized, and the requirements of the real assembly line cannot be met.

[0030] 5) After assembly, manual spot welding is still required, which adds an additional process, which greatly limits the efficiency of the device with a relatively high degree of automation
