[0002] Automobile straight pipes play an important role in automobile systems. They usually refer to pipes with a straight shape used to transport gas or liquid. The length and diameter of automobile straight pipes are the main factors to measure their quality. In the process of length detection of automobile straight pipes, corresponding length gauges are required.

[0003] At present, the automobile straight pipe length inspection tool in the existing technology mainly includes a support bracket and a measuring plate. The straight pipe is placed on the support bracket, and then the measuring plate is used to detect its length. The straight pipe is then taken out from the support bracket to complete the automobile straight pipe length detection step. In this process, the process of taking the straight pipe out from the support bracket may occupy the detection channel of the next straight pipe and reduce the detection efficiency of the automobile straight pipe length to a certain extent.

[0004] Therefore, in order to solve the above problems, an automobile straight pipe length checking fixture is proposed. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] See also Figure 1 - Figure 4The utility model provides a car straight pipe length measuring tool, including a side plate 1, a side wall of the side plate 1 is provided with a through opening 11 near the corner, a measuring plate 2 is slidably passed through the inner wall of the through opening 11, a mounting slot 12 is provided on one side of the side plate 1, a center gear 13 is installed at the center of the side wall of the mounting slot 12, two racks 3 are installed inside the mounting slot 12, the two racks 3 are rotationally symmetrical along the axial direction of the center gear 13, and the adjacent side walls of the two supporting rods 31 are fixed with arc support blocks 32. The side wall of the side plate 1 is installed with a motor 4 through a bracket, and the output shaft of the motor 4 passes through the side plate 1 and is fixed to the axial center of the center gear 13. The bottom surface of the measuring plate 2 away from the end where the motor 4 is located is fixed with a limiting rod 21, and a limiting component 5 is installed on the other side of the side plate 1. The measuring plate 2 slidably installed inside the through opening 11 plays a major supporting role for the car straight pipe, and the mobile measuring When the cam 31 is in the normal position, the cam 32 is in the normal position, and the cam 32 is in the normal position, so that the cam 32 is in the normal position, and the cam 32 is in the normal position, so that the cam 32 is in the normal position, and the cam 32 is in the normal position, so that the cam 32 is in the normal position, and the cam 32 is in the normal position.

[0025] like Figure 1 As shown, a plurality of limiting through holes 22 are provided at the top center of the measuring plate 2. The plurality of limiting through holes 22 are provided at equal intervals along the side wall edge of the measuring plate 2. The relative position of the measuring plate 2 and the side plate 1 is limited by the mutual cooperation between the limiting through holes 22 and the limiting assembly 5.

[0026] like Figure 2 and Figure 4As shown, the limiting assembly 5 includes a limiting column 51, which slides through the inner wall of one of the limiting through holes 22. One end of the limiting column 51 is fixedly connected to a base 52. The side wall of the base 52 is provided with a limiting card slot 521. A card rail 53 is slidably installed between the inner walls of the limiting card slot 521. The side wall of the card rail 53 is fixedly connected to the side wall of the side plate 1. The bottom surface of the base 52 is vertically fixed with an elastic telescopic rod 54. One end of the elastic telescopic rod 54 is fixedly connected to the side wall of the card rail 53 through a bracket. The rail 53 fixed to the side wall of the side panel 1 limits its position by engaging with the limiting groove 521 on the side wall of the base 52, so that the limiting column 51 and the base 52 as a whole can only change their positions in the vertical direction. When the limiting column 51 and the limiting through-hole 22 are engaged with each other, the relative position of the measuring plate 2 is limited, realizing the limiting effect of the limiting assembly 5 on the measuring plate 2, and the elastic telescopic rod 54 provides elastic force for the mutual engagement of the limiting column 51 and the limiting through-hole 22.

[0027] like Figure 3 As shown, rollers 33 are installed at the bottom of one end of each of the two supporting rods 31. The bottom cross-section of the rollers 33 is coplanar with the bottom surface of the side panel 1. The rollers 33 support the other ends of the supporting rods 31, so that the supporting rods 31 and the straight tubes thereon can remain level, thereby increasing the rationality of the device structure.

[0028] like Figure 3 As shown, the side walls of the two racks 3 are provided with strip-shaped limiting grooves 34, which are respectively engaged with the top and bottom convex rails of the mounting slot 12. The racks 3 cooperate with the mounting slot 12 through the strip-shaped limiting grooves 34, thereby increasing the rationality of the device structure.

[0029] Working principle: The measuring plate 2 slidably installed inside the through opening 11 plays a major supporting role for the automobile straight pipe. After moving the measuring plate 2 to the standard position, it and the limit lever 21 are fixed as a whole. At this time, the straight pipe can be placed between the supporting rods 31 on both sides and the arc-surface supporting block 32 to support it. When the two ends of the straight pipe can respectively contact the adjacent side walls of the side plate 1 and the limit lever 21, the straight pipe length is qualified. At this time, start the motor 4 to rotate the center gear 13. Under the action of the center gear 13, the two racks 3 and the supporting rod 31 are moved away from each other until the straight pipe is separated from the device. Then reverse the motor 4 to reset the rack 3, the supporting rod 31 and the arc-surface supporting block 32, and continue to feed the straight pipe. The detection shows that the rail 53 fixed to the side wall of the side panel 1 limits its position by mutual fit with the limiting slot 521 on the side wall of the base 52, so that the limiting column 51 and the base 52 as a whole can only change their position in the vertical direction. When the limiting column 51 and the limiting through-hole 22 fit together, the relative position of the measuring plate 2 is limited, and the limiting component 5 has a limiting effect on the measuring plate 2, and the elastic telescopic rod 54 provides an elastic force for the mutual clamping of the limiting column 51 and the limiting through-hole 22. The roller 33 supports the other end of the supporting rod 31, so that the supporting rod 31 and the straight tube thereon can remain horizontal. The rack 3 cooperates with the installation slot 12 through the strip limiting slot 34 to increase the rationality of the device structure.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
