Abstract
The utility model discloses an extended surface tube welded fastening anchor clamps, including punch holder and lower plate, connecting plate hinged joint is passed through to punch holder and lower plate one end, and the other end passes through handle activity block, handle fixed connection is on the lower plate, the punch holder expansion end is equipped with ARC guide portion, be provided with the roll locating pin with the ARC guide sliding fit of portion on the handle, the inboard symmetry of punch holder and lower plate sets up the semicircle clamping part. Just guaranteed the center of fin on the pipe these anchor clamps are not getting into welding equipment with the pipe fitting when using before, the centre gripping is stable, and it is effectual to feel relieved, and easy operation has alleviateed workman intensity of labour, the convenient production of welding in batches improves work efficiency.
Description
Technical field
The utility model relates to boiler plant technical field, especially relates to a kind of extended surface tube and is welded and fixed fixture.
Background technology
In boiler industry, the making of extended surface tube is except most important weldquality ensures, fin is also very important factor at tube center.Usually adopt automatic welding device self roller to control fin on the center line of pipe in current boiler industry, this kind of processing mode is just by the workman center feeling assessment fin soon, and production efficiency is low, and weldment is second-rate.
Utility model content
In order to overcome above-mentioned existing technological deficiency, it is stable that the purpose of this utility model is to provide a kind of clamping, to the position centering effect of fin on pipe good be welded and fixed fixture.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is that a kind of extended surface tube is welded and fixed fixture, comprises train wheel bridge and lower plate; Described train wheel bridge and lower plate one end are by connecting plate chain connection, and the other end is movably fastened by handle, and described handle is fixedly connected on lower plate; Train wheel bridge movable end is provided with arc guide rail portion, described handle is provided with the scroll positioning pin be slidably matched with arc guide rail portion; Semicircle clamping part is symmetrical arranged inside described train wheel bridge and lower plate; Train wheel bridge and lower plate form the clamping cavity to fin when extended surface tube welds by the chain connection of connecting plate.By this setting tool, when fin assembling spot welding, fixture clamps pipe and band steel, and fin is fixed on tube center by fixture, reach fin to be controlled on pipe center line when not entering automatic welding equipment, thus ensure better fin center fixed mass.
As preferably, the logarithm that described semicircle clamping part is arranged is not less than 2, disposablely carries out centering to many pipes and fin and clamps, and increases work efficiency.
Compared with prior art, the beneficial effects of the utility model are: pipe fitting is just ensured the center of fin on pipe by this fixture in use before not entering welding equipment, and clamping is stable, and centering effect is good, simple to operate, alleviates labor strength; Convenient batch welding production, increases work efficiency.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is main structure schematic diagram of the present utility model;
Fig. 2 is left view of the present utility model.
Mark in figure: train wheel bridge 1, lower plate 2, connecting plate 3, handle 4, arc guide rail portion 5, scroll positioning pin 6 and semicircle clamping part 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as shown in Figures 1 and 2, the utility model is that a kind of extended surface tube is welded and fixed fixture, comprises train wheel bridge 1 and lower plate 2; Described train wheel bridge 1 and lower plate 2 one end are by connecting plate 3 chain connection, and the other end is movably fastened by handle 4, and described handle 4 is fixedly connected on lower plate 2; Train wheel bridge 1 movable end is provided with arc guide rail portion 5, described handle 4 is provided with the scroll positioning pin 6 be slidably matched with arc guide rail portion 5; Semicircle clamping part 7 is symmetrical arranged inside described train wheel bridge 1 and lower plate 2; Train wheel bridge 1 and lower plate 2 form the clamping cavity to fin when extended surface tube welds by the chain connection of connecting plate 3.
First handle 4 position is pulled downwards, scroll positioning pin 6 opens fixture along with arc guide rail portion 5 slide downward, now fixture is in unlocked state, ready pipe is placed in semicircle clamping part 7, fin is placed on pipe side, finally up pulled by handle 4, fixture is locked, can carry out integral solder after locking by being pushed in welding equipment by welding pipe fitting.By this setting tool, when fin assembling spot welding, fixture clamps pipe and band steel, and fin is fixed on tube center by fixture, reach fin to be controlled on pipe center line when not entering automatic welding equipment, thus ensure better fin center fixed mass.The effect of train wheel bridge 1 and lower plate 2 is clamping pipe and will controls fin on tube center line position, and clamping plate size is chosen according to using the specification size of pipe.Semicircle clamping part 7 on upper lower plate is other to be needed to be polished into impulse-free robustness, avoids the impact on pipe clamping stability and tube surface quality; Train wheel bridge 1 and lower plate 2 are by connecting plate 3 chain connection and formation clamps step, and the size step of this position is fin position location.Upper lower plate adopts steel plate materials to make usually, and Main Function ensures that the positioning clamping of pipe and fin is accurate, do not departed from by the traction of equipment simultaneously.Handle 4 is provided with the scroll positioning pin 6 be slidably matched with arc guide rail portion 5, scroll positioning pin 6 handle 4 upwards pull close up fixture time and train wheel bridge 1 on arc guide rail portion 5 Structure deformation and slide and reach dead-centre position and make lower plate locked, scroll positioning pin 6 effectively ensure that the clamping stability to pipe and fin, facilitates operative.
Embodiment 2, decision design is carried out to the logarithm that semicircle clamping part 7 is arranged in the basis of embodiment 1, and the logarithm that described semicircle clamping part 7 is arranged is not less than 2, disposablely carries out centering to many pipes and fin and clamps, and increases work efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
