Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a mechanical structure of an oil tank wave-break plate edge welding device and a working method thereof. Background Art

[0002] When the viscosity of the medium being transported by a tank truck is low and the filling volume is between 20% and 80%, a wave breakers must be installed inside the tank. When the liquid inside the tank fluctuates, the wave breakers inside the tank can be used to reduce the fluctuations and impacts of the liquid inside the tank, thereby improving the stability of the tank truck. The wave breakers need to be edge-welded before leaving the factory. In the traditional welding process of oil tank wave breakers, in most cases, the bending and welding operations are performed separately in two workshops, requiring workers to pre-press the bend and weld separately. If the enclosure is too long, a dedicated person is required to be responsible for feeding the wave breakers. The welding process is both physically and humanly intensive, and production efficiency is relatively low. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a mechanical structure and working method of an oil tank wave-breaking plate edge welding device, which can not only bend and weld the wave-breaking plate on the same workbench, but also process wave-breaking plates of various specifications.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A mechanical structure of an oil tank wave-blocking plate edge welding device includes a workbench, on which a first conical plate, a second conical plate, a third conical plate, a first support plate, a second support plate, and a third support plate are sequentially arranged from left to right in parallel with each other, wherein the first conical plate and the first support plate are fixedly connected by a first connecting rod, the second conical plate and the second support plate are fixedly connected by a second connecting rod, and the third conical plate and the third support plate are fixedly connected by a third connecting rod;

[0006] The bottom surfaces of the first conical plate, the second conical plate and the third conical plate are all fixedly connected to bearings, and the inner rings of the bearings are fixedly connected to screw rods; the workbench is provided with a groove for accommodating the screw rods, a nut is fixedly connected in the groove, the screw rods are threadedly connected to the nut, and one end of the screw rod extends out of the groove and is fixedly connected to a hand crank wheel;

[0007] A top plate is fixedly installed on the top of the workbench through a supporting rod, and a first hydraulic rod and a second hydraulic rod are fixedly installed on the left and right sides of the bottom of the top plate respectively, an extruded plate is fixedly installed on the bottom of the first hydraulic rod, and a welding head is fixedly installed on the bottom end of the second hydraulic rod. The extruded plate presses the wave-blocking plate located on the first conical plate, the second conical plate and the third conical plate downward to bend it, and the bent wave-blocking plate is placed on the first support plate, the second support plate and the third support plate to be welded by the welding head.

[0008] Furthermore, a group of slide grooves are opened on the workbench, and sliders are fixedly connected to both sides of the bottom of the first conical plate, the second conical plate, the third conical plate, the first support plate, the second support plate and the third support plate, and the sliders are slidably connected in the slide grooves.

[0009] Furthermore, the bottom surfaces of the first conical plate, the second conical plate and the third conical plate are all fixedly connected with a fixing plate slidably connected to the groove, a circular hole is opened on the fixing plate, and the outer ring of the bearing is fixedly connected to the inner surface of the circular hole.

[0010] Furthermore, the bottom end of the first hydraulic rod is fixedly connected to the first vertical rod, and the extruded plate is fixedly connected to the bottom end of the first vertical rod; the bottom end of the second hydraulic rod is fixedly connected to the second vertical rod, and the upper end of the welding head is fixedly connected to the second vertical rod.

[0011] Furthermore, the first conical plate, the second conical plate and the third conical plate have the same size;

[0012] The first support plate, the second support plate and the third support plate have the same size.

[0013] Furthermore, four supporting legs are fixedly connected to the bottom of the workbench.

[0014] Furthermore, the first connecting rod, the second connecting rod and the third connecting rod are all U-shaped.

[0015] A working method of a mechanical structure of an oil tank wave plate edge welding device includes the following steps:

[0016] Step 1: First, adjust the distance between the first conical plate, the second conical plate and the third conical plate by rotating the hand wheel. The distance between the first support plate, the second support plate and the third support plate is also adjusted synchronously.

[0017] Step 2: Place the wavebreak to be bent on top of the first conical plate, the second conical plate, and the third conical plate, and control the extrusion forming plate to move downward by the first hydraulic rod. The extrusion forming plate cooperates with the first conical plate, the second conical plate, and the third conical plate to extrude and bend the wavebreak.

[0018] Step 3: Place the bent wave-breaking plate on the first, second and third support plates according to the creases, so that the surface of the wave-breaking plate fits tightly with the first, second and third support plates;

[0019] Step 4: Turn on the control switch of the welding head, and control the height of the welding head through the second hydraulic rod to weld the wave breakers that need to be welded.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention can drive the screw to rotate and move left and right relative to the nut by a hand-cranked wheel, thereby driving the first conical plate, the second conical plate and the third conical plate connected thereto to move left and right, thereby adjusting the spacing between the first conical plate, the second conical plate and the third conical plate, and processing wave-stopping plates with different wave spacings; at the same time, the first conical plate drives the first support plate to move through the first connecting rod, the second conical plate drives the second support plate to move through the second connecting rod, and the third conical plate drives the third support plate to move through the third connecting rod, thereby synchronously adjusting the spacing between the first support plate, the second support plate and the third support plate, and making the spacing between the first support plate, the second support plate and the third support plate adapt to the spacing between the first conical plate, the second conical plate and the third conical plate, so that the surface of the bent wave-stopping plate is completely fitted with the first support plate, the second support plate and the third support plate, thereby better fixing and effectively preventing the wave-stopping plate from moving during the welding process. It can be seen that the present invention can not only bend and weld wave-stopping plates on the same workbench, thereby improving production efficiency, but also can process wave-stopping plates of various specifications and ensure the smooth progress of welding work.

[0022] By coordinating the slide groove with the slider, not only can the first conical plate, the second conical plate, the third conical plate, the first support plate, the second support plate and the third support plate be more stable during movement, but they can also move within a limited motion trajectory, preventing processing errors caused by offset.
