A rear longitudinal beam fuel tank bracket positioning device

Abstract

This utility model relates to the field of positioning device technology and discloses a rear longitudinal beam fuel tank bracket positioning device, including a mounting shell. Slide grooves are formed on both sides of the top of the mounting shell. A first slide rod is fixedly connected to the inner wall of the slide groove. A slide plate is slidably connected to the surface of the first slide rod. A first extension plate is fixedly connected to both sides of the top of the slide plate. Bolts are threaded into the interior of the first extension plate. This rear longitudinal beam fuel tank bracket positioning device allows the operator to place the fuel tank bracket on top of the slide plate and tighten the bolts to move the push plate. This causes the push plate to clamp and fix the fuel tank bracket to the first extension plate. The operator then adjusts the position of the slide plates on both sides to a designated position on the surface of the fuel tank, and inserts a limiting rod into a limiting hole for fixation. This allows the device to clamp and position fuel tank brackets of different sizes, and the spacing of the fuel tank brackets can be adjusted for fixation, making the device suitable for assembling and using fuel tanks and fuel tank brackets of different sizes.

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments.

[0025] Reference Figure 1 and Figure 2As shown, in this embodiment: the top of the limiting rod 9 is fixedly connected with a flat round block 11, the bottom of the flat round block 11 is fixedly connected with a first spring 12, the bottom of the first spring 12 is fixedly connected to the top of the second extension plate 8, and the staff pulls the flat round block 11 upward to drive the first spring 12 to store force. When the staff releases the flat round block 11, the force generated by the first spring 12 is released, so that the first spring 12 rebounds and pulls the flat round block 11 to push the limiting rod 9 downward into the inner wall of the limiting hole 10, so that the staff can control the position of the limiting rod 9 through the force generated by the first spring 12 to plug the limiting hole 10.

[0026] Reference Figure 1 and Figure 2 As shown, in the present embodiment: a plurality of digital scales 13 are fixedly connected to the surface of the mounting shell 1, and the number of the digital scales 13 is the same as the number of the limiting holes 10. The digital scales 13 opened on the surface of the mounting shell 1 correspond to the number of the limiting holes 10, so that when the staff adjusts the position of the slide plate 4, the positions of the slide plates 4 on both sides can be clearly identified, which makes it easier for the staff to adjust the slide plates 4 on both sides to the specified positions.

[0027] Reference Figure 1 , Figure 3 and Figure 4 As shown, in the present embodiment: one end of the slide plate 4 is fixedly connected with the second spring 14, and the end of the second spring 14 away from the slide plate 4 is fixedly connected to one side of the inner wall of the slide groove 2, and the staff pulls the slide plate 4 to adjust the position to drive the second spring 14 to store force, and when the staff releases the slide plate 4, the force generated by the second spring 14 is released, so that the second spring 14 pulls the slide plate 4 to reset, so that the staff can adjust the position of the slide plate 4 to the same position next time.

[0028] Reference Figure 2 As shown, in this embodiment: the push plate 7 is made of hard rubber. By making the push plate 7 of hard rubber material, it is not easy to scratch the bracket when the push plate 7 clamps the fuel tank bracket. At the same time, the friction between the bracket and the push plate 7 is increased, which makes it easier for the staff to clamp and fix the fuel tank bracket.

[0029] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in this embodiment: the front end of the mounting shell 1 is fixedly connected with a second sliding rod 15, both ends of the surface of the second sliding rod 15 are slidably connected with sliding blocks 16, one side of the sliding block 16 is fixedly connected with a clamping plate 17, the front end of the sliding block 16 is threadedly connected with a threaded rod 18, both sides of the front end of the mounting shell 1 are fixedly connected with extension blocks 19, one side of the extension block 19 is fixedly connected with a rotating rod 20, the surface of the rotating rod 20 is rotatably connected to the two sides of the threaded rod 18, the staff twists the threaded rod 18 to drive the sliding block 16 to slide on the surface of the second sliding rod 15, and adjusts the position of the second sliding rod 15 so that the clamping plate 17 clamps the oil tank, thereby positioning the position of the device on the oil tank, so that the clamped oil tank brackets can be evenly distributed on both sides of the oil tank.

[0030] Reference Figure 5 As shown, in this embodiment: a through hole 21 is opened at the top of the slider 16, and the through hole 21 is opened, so that the staff can add lubricating oil to the surface of the threaded rod 18 through the through hole 21, thereby reducing the friction between the slider 16 and the threaded rod 18, so that the movement of the slider 16 is smoother when the threaded rod 18 rotates.

[0031] The working principle of the utility model is as follows: the staff places the fuel tank bracket on the top of the slide plate 4 and screws the bolt 6 to drive the push plate 7 to move, so that the push plate 7 pushes the fuel tank bracket and the first extension plate 5 to form a clamping fixation, and then the staff adjusts the positions of the slide plates 4 on both sides to the specified positions on the surface of the fuel tank, and then inserts the limit rod 9 into the limit hole 10 for fixing, so that the device can clamp and position fuel tank brackets of different sizes, adjust the spacing of the fuel tank brackets for fixing, so that the device can be suitable for the assembly and use of fuel tanks and fuel tank brackets of different sizes, and the staff can adjust the positions of the slide plates 4 on both sides to the specified positions on the surface of the fuel tank, and then insert the limit rod 9 into the limit hole 10 for fixing, so that the device can clamp and position fuel tank brackets of different sizes, adjust the spacing of the fuel tank brackets for fixing, and make the device suitable for the assembly and use of fuel tanks and fuel tank brackets of different sizes. The flat round block 11 is pulled upward to drive the first spring 12 to store force. When the staff releases the flat round block 11, the force generated by the first spring 12 is released, so that the first spring 12 rebounds and pulls the flat round block 11 to push the limit rod 9 downward to insert into the inner wall of the limit hole 10, so that it is convenient for the staff to control the position of the limit rod 9 to plug the limit hole 10 through the force generated by the first spring 12. The digital scale 13 on the surface of the mounting shell 1 corresponds to the number of the limit hole 10, so that when the staff adjusts the position of the slide plate 4, the position of the slide plate 4 on both sides can be clearly identified. When the staff releases the slide plate 4, the force generated by the second spring 14 is released, so that the second spring 14 pulls the slide plate 4 to reset, so that the staff can adjust the position of the slide plate 4 to the same position next time. By making the push plate 7 of hard rubber material, it is not easy to scratch the bracket when the push plate 7 clamps the fuel tank bracket. At the same time, the friction between the bracket and the push plate 7 is increased, which is more convenient for the staff to clamp and fix the fuel tank bracket. By screwing the threaded rod 18 by the staff, the slider 16 slides on the surface of the second slide rod 15, and the position of the second slide rod 15 is adjusted, so that the clamping plate 17 clamps the fuel tank, thereby positioning the position of the device on the fuel tank, so that the clamped fuel tank bracket can be evenly distributed on both sides of the fuel tank. Through the through hole 21, the staff can add lubricating oil to the surface of the threaded rod 18 through the through hole 21, reduce the friction between the slider 16 and the threaded rod 18, and make the movement of the slider 16 smoother when the threaded rod 18 rotates.
