Description

Technical Field

[0001] The utility model belongs to the technical field of oil tank processing, in particular to an oil tank splicing device. Background Art

[0002] The hydraulic oil tank is an indispensable and important component in the hydraulic system. It is mainly used to store the oil required to ensure the operation of the hydraulic system. Its design and function directly affect the efficiency and reliability of the entire system. Through reasonable design and maintenance, the hydraulic oil tank can ensure the quality and performance of the hydraulic oil, thereby ensuring the normal operation of the hydraulic equipment and extending its service life. There is currently a separate hydraulic oil tank, which is mainly composed of a panel, a cover, an oil suction pipe, an air filter, an oil return pipe, a liquid level gauge, a partition, a filter, etc. This type of tank is flexible in layout and easy to maintain, and is commonly used in mobile operating machinery and fixed operating machinery systems. However, in order to make full use of materials, reduce waste, thereby reducing production costs, and making manufacturing more flexible, the hydraulic oil tank body is generally formed by welding rather than direct forming. The welding operation of this tank is inconvenient, and it is necessary to design an auxiliary device that facilitates welding operations to improve work efficiency. Utility Model Content

An extrusion plate 1011; the second splicing frame 2 is open on one side close to the first splicing frame 1, and two symmetrical second extrusion plates 2011 are provided on the open side. The two second extrusion plates 2011 are provided with a second rotating rod 202 at one end away from the symmetry axis. One end of the two second rotating rods 202 can be rotatably installed on the top plate of the second splicing frame 2, and the other end can be rotatably installed on the bottom plate of the second splicing frame 2.

[0026] Specifically, the first telescopic drive device 103 and the second telescopic drive device 203 may be pneumatic or electric.

[0027] It should be noted that the fuel tank shell to be spliced ​​includes a first panel 401, a second panel 402 and a cover plate 403. The first panel 401 and the second panel 402 are both composed of a bottom plate and two side plates. When using this device, the fuel tank cover plate 403 is placed on the top of the loading platform 3, the bottom plate of the first panel 401 of the fuel tank is placed between the first extrusion plate 1011 and the loading platform 3, and the two side plates of the first panel 401 are placed on both sides of the loading platform 3; the bottom plate of the second panel 402 of the fuel tank is placed between the second extrusion plate 2011 and the loading platform 3, and the two side plates of the second panel 402 are placed on both sides of the loading platform 3. The side panels are respectively placed on both sides of the loading platform 3, and the driving force is provided by the first telescopic driving device 103 to push the two first extrusion plates 1011 toward the first enclosure 401, thereby pressing the first enclosure 401 against the wall of the loading platform 3.

The above design can avoid the first enclosure 401 and the second enclosure 402 from shaking during welding, making the welding operation more convenient to improve work efficiency.

[0028] In one embodiment, see Figure 2As shown, two first limit blocks 104 are provided on the top surface of the first splicing frame 1, and two second limit blocks 1041 are provided on the inner bottom surface.

Through the cooperation of the first rotating rod 102 and the limit blocks, when the first extrusion plate 1011 is subjected to driving force, the connected first rotating rod 102 can rotate more smoothly in the limit blocks, thereby reducing the probability of jamming.

[0029] In one embodiment, two third limit blocks 205 are provided on the inner top surface of the second splicing frame 2, and two fourth limit blocks 206 are provided on the inner bottom surface.

Through the cooperation between the second rotating rod 202 and the limit blocks, when the second extrusion plate 2011 is driven, the connected second rotating rod 202 can rotate more smoothly in the limit blocks, thereby reducing the probability of jamming.

[0030] In one embodiment, since the height of the second enclosure 402 is lower than that of the first enclosure 401 , in order to match the enclosure structure and reduce the production cost of the splicing device, the height of the second splicing frame 2 is lower than that of the first splicing frame 1 .

[0031] In one embodiment, see Figure 3 As shown, it also includes two first limit plates 101 symmetrically arranged on both sides of the loading platform 3 and two second limit plates 201 symmetrically arranged on both sides of the loading platform 3. One end of the first limit plate 101 is fixedly connected to the first rotating rod 102, and the other end is set toward the second splicing frame 2. One end of the second limit plate 201 is fixedly connected to the second rotating rod 202, and the other end is set toward the first splicing frame 1. When in use, the side plate of the first enclosure 401 is placed between the first limit plate 101 and the loading platform 3, and the side plate of the second enclosure 402 is placed between the second limit plate 201 and the loading platform 3. The first enclosure 401 and the second enclosure 402 can be limited by the limit plate to avoid the welding position of the first enclosure 401 and the second enclosure 402 being too misaligned, thereby affecting the welding.

[0032] In one embodiment, see Figure 1 As shown, an operation window 105 is provided on each of the two first limiting plates 101. The operation window 105 is provided at a position at the bottom of the first limiting plate 101 close to the second splicing frame 2. This position is the junction of the first enclosure 401 and the second enclosure 402. The welding operation can be performed more conveniently through the operation window 105.

[0033] In one embodiment, a limiting protrusion 204 is provided on the top of each of the two second limiting plates 201. The bottom of the limiting protrusion 204 is lower than the worktable 3 in horizontal height, and the top of the limiting protrusion 204 is higher than the worktable 3 in horizontal height. The position of the cover 403 on the top of the worktable 3 can be more conveniently calibrated through the limiting protrusion 204.

[0034] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
