Description

Technical Field

[0001] The utility model belongs to the technical field of automobile oil tanks, and in particular relates to a processing fixture for an automobile oil tank body. Background Art

[0002] The fuel container on the car is a special container for storing hydraulic oil or hydraulic fluid in the hydraulic system. The fuel tank can be divided into open fuel tank and closed fuel tank. The fuel tank must have a large enough volume. The oil suction pipe and the oil return pipe should be inserted below the minimum liquid level to prevent air bubbles caused by suction and oil return splashing. The distance between the oil suction pipe and the oil return pipe should be as far as possible, and a partition should be set between them. In order to keep the oil clean, the fuel tank should have a peripheral sealed cover with an air filter installed on the cover. The bottom of the fuel tank should be more than 150mm from the ground. Full attention should be paid to the anti-corrosion treatment of the inner surface of the fuel tank. During the automobile manufacturing process, the hydraulic press is required to clamp it before continuing production.

[0003] However, there are some problems with the prior art: the existing automobile fuel tank clamp is usually manually adjusted for clamping strength and angle, and sometimes due to fatigue of workers from long-term work, deviations may occur when adjusting the clamp, resulting in the automobile fuel tank not being clamped, causing damage, which not only wastes workers' time but also easily causes damage to the automobile fuel tank. At the same time, after the automobile fuel tank is completed, it is inconvenient to carry the automobile fuel tank because the fuel tank is close to the frame and is not easy to be taken out. Therefore, we propose a automobile fuel tank body processing fixture. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a vehicle fuel tank body processing fixture, which can start the hydraulic press to rotate the clamping block on the driving column, and then clamp the four corners of the fuel tank to fix the fuel tank on the frame. At the same time, after the fuel tank is completed, the fuel tank is lifted up by the top shell assembly, so as to automatically clamp the fuel tank, which is less prone to deviation and can more stably fix the fuel tank. Lifting the fuel tank also makes it easier for workers to carry the fuel tank.

[0026] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 4 As shown, an automobile fuel tank body processing fixture provided by the embodiment of the utility model comprises:

[0028] The frame 1 has two groups of support blocks on its lower surface for supporting its surface, and the upper surface of the frame 1 is detachably connected with a gasoline tank 4, and after the gasoline tank 4 is manufactured, it can be replaced with a new one.

[0029] The four corners of the frame 1 surface are fixedly installed with clamping components 2. After the gasoline tank 4 is placed on the surface of the frame 1, the clamping components 2 clamp the four corners of the gasoline tank 4 so that the gasoline tank 4 can be fixed on the surface of the frame 1 for manufacturing.

[0030] Top shell assemblies 3 are fixedly installed on both sides of the surface of the frame 1. After the fuel tank 4 is manufactured, the top shell assembly 3 will lift up the fuel tank 4. Then the staff can hold the bottom of the fuel tank 4 to move the fuel tank 4 down, or use some carrying tools to move the fuel tank 4 down from the upper surface of the frame 1.

[0031] Support columns 7 are fixedly installed at the four corners of the frame 1, and the support columns 7 are located on one side of the clamping assembly 2. The support columns 7 support the four corners of the fuel tank 4. Four groups of guide heads 8 are fixedly installed on the upper surface of the frame 1. There are four holes at the four corners of the fuel tank 4. When the fuel tank 4 is placed, the four holes are aligned with the four groups of guide heads 8, and then the four groups of guide heads 8 are inserted into the four holes. The four groups of guide heads 8 are respectively located on one side of the support columns 7. Four groups of material guide holes 6 are opened on the surface of the frame 1. The material guide holes 6 remove the debris dropped from the fuel tank 4, and the four groups of material guide holes 6 are located between the two groups of top shell assemblies 3. Several groups of positioning pins 5 are fixedly installed on the surface of the frame 1. After the fuel tank 4 is placed on the surface of the frame 1 and the clamping assembly 2 clamps the fuel tank 4, the positioning pins 5 are close to the edge of the fuel tank 4 to position the fuel tank 4. Several groups of positioning pins 5 are respectively located around the surface of the frame 1.

[0032] Circular holes are formed at the four corners of the frame 1 , and one end of the clamping assembly 2 passes through the circular hole and is located on the surface of the frame 1 .

[0033] The clamping assembly 2 includes a hydraulic press 201, which is fixedly installed on the lower surface of the frame 1. A driving column 202 is fixedly installed on one end of the output shaft of the hydraulic press 201. The driving column 202 passes through a circular hole and is located on the surface of the frame 1. A clamping block 203 is rotatably connected to the surface of the driving column 202. A first rotating shaft 204 is provided between the clamping block 203 and the driving column 202. The clamping block 203 is rotatably connected to the driving column 202 through the first rotating shaft 204. By starting the hydraulic press 201, the driving column 202 is driven to move upward. At the same time, when the driving column 202 is upward, the first rotating shaft 204 rotates, and one end of the clamping block 203 will be pressed downward to clamp the gasoline tank 4.

[0034] A positioning block 207 is fixedly installed on the upper surface of the hydraulic press 201. The positioning block 207 is set in a convex shape. Both ends of the positioning block 207 are rotatably connected with rotating blocks 205. Second rotating shafts 206 are set on both sides of the rotating block 205. One end of the rotating block 205 is rotatably connected to the positioning block 207, and the other end of the rotating block 205 is rotatably connected to the clamping block 203. When the clamping block 203 is pressed down, the rotating block 205 will be tilted forward, pushing the clamping block 203 to be pressed down, playing a linkage role. After the clamping block 203 clamps the edge of the gasoline tank 4, the hydraulic press 201 stops running.

[0035] The top shell assembly 3 includes a motor 301 and a fixed plate 303. The motor 301 is fixedly installed on the lower surface of the frame 1. The output shaft of the motor 301 passes through the frame 1 and is located on the surface of the frame 1. The fixed plate 303 is fixedly installed on the surface of the frame 1 and is located on one side of the motor 301. A slide groove 9 is provided on the side wall of the fixed plate 303. The slide groove 9 is used to connect with the slider 304. When the clamping block 203 releases the gasoline tank 4, the motor 301 of the top shell assembly 3 starts.

[0036] A threaded column 302 is fixedly installed at one end of the output shaft of the motor 301, and a slider 304 is threadedly connected to the surface of the threaded column 302. One end of the slider 304 is slidably connected to the slide groove 9, and a top block 305 is fixedly installed at the other end of the slider 304. The top block 305 is set in an L shape. After the motor 301 is started, the output shaft of the motor 301 starts to rotate, and the electric threaded column 302 rotates. While the threaded column 302 rotates, it will push the slider 304 to slide upward. A threaded hole is provided at the center end of the slider 304, so that it can slide up or down under the rotation of the thread of the threaded column 302. At the same time, the lifting of the slider 304 can drive the lifting of the top block 305, so that the top block 305 can lift the gasoline tank 4.
