[0002] On heavy trucks, toolboxes are usually used to store some commonly used or necessary tools, spare parts and maintenance equipment, etc. These tools can help drivers quickly solve problems in emergencies and ensure safe and smooth driving. The toolboxes of most heavy trucks are usually stored in a specific location at the rear or bottom of the vehicle body.

[0003] At present, in order to reduce the manufacturing cost of tool boxes and achieve lightweight tool boxes, most tool boxes are made of plastic or composite materials, and the tool boxes are fixed to the vehicle body by bolts. However, since the tool boxes are made of plastic or composite materials, the strength of the mounting holes is low. During driving, the shaking of the vehicle body will cause wear between the mounting holes and the bolts, resulting in damage to the mounting holes or enlargement of the size, and unstable installation of the tool box. In order to improve the strength of the mounting holes of the tool box and avoid friction damage to the mounting holes, a common measure is to install tubular rivets at the mounting holes and fix them with rivet heads, so that the bolts are installed in the rivets and no longer directly contact the mounting holes.

[0004] The tubular rivets at the mounting holes of the existing tool box are mostly manually riveted (manually operated riveting gun). Since the tool box has two relatively arranged hole seats (including mounting holes), the manual riveting method is inefficient, has low installation accuracy, and has high work intensity. At the same time, due to the limitation of the tool box structure, the tool box needs to be limited and the hole seats need to be supported during the riveting process, which requires the cooperation of multiple people.

[0030] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0031] In a typical implementation of the present invention, Figure 1-Figure 4 As shown, a rivet assembly tool for a heavy truck tool box is proposed, comprising: a workbench, a mounting frame is fixedly installed on the workbench, two cylinders 11 are fixedly provided on the mounting frame, the two cylinders 11 are connected to the same air source, and the two cylinders 11 are connected to the same pedal switch 2, and the two cylinders 11 can be controlled to work synchronously through the pedal switch 2 to perform riveting work on the two hole seats 15 of the tool box at the same time.

[0032] The two cylinders 11 are arranged side by side, and the two cylinders 11 are located above the workbench surface. A first limit block 5 is detachably provided on the side of the workbench, and a second limit block 6 is detachably installed on the workbench surface. The first limit block 5 and the second limit block 6 are both L-shaped plate structures, and both are fixed on the workbench by bolts. The position can be adjusted according to needs, and the position of the hole seat 15 can be limited by the cooperation of the first limit block 5 and the second limit block 6.

[0033] Specifically, the workbench includes a bracket 1 and a support plate 4, the support plate 4 is fixedly installed on the bracket 1 by welding or other means, the mounting frame includes a vertical frame 9 and a fixed plate 10, the vertical frame 9 is fixedly set on the support plate 4 by welding or bolting, the fixed plate 10 is fixedly installed on the vertical frame 9 by bolting, there are two fixed plates 10, each of which is fixedly installed with a cylinder 11, and a plurality of bolt holes are provided on the vertical frame 9, and the positions of the two fixed plates 10 can be adjusted according to needs to adapt to tool boxes of different specifications, that is, the relative positions of the two cylinders 11 can be adjusted according to the relative positions of the two hole seats 15.

[0034] The two cylinders 11 are respectively connected to the air source through the air pipe, and are connected to the same pedal switch 2 through the air pipe. The pedal switch 2 is placed on the ground. The synchronous action of the two cylinders 11 can be controlled by the foot pedal switch 2, so that the two hole seats 15 can be processed synchronously, which improves the work efficiency and accuracy. An oil-water separator 3 is fixedly installed on the bracket 1. The pipelines connecting the two cylinders 11 to the air source are also connected to the oil-water separator 3 to separate the moisture in the compressed air and accurately adjust the air pressure. A throttle valve 12 is installed on each cylinder 11 to control the flow rate of compressed air.

[0035] The first limit block 5 is fixedly installed on the side of the support plate 4 by bolts, and the second limit block 6 is fixedly installed on the upper surface of the support plate 4 by bolts. The second limit block 6 is close to the side of the support plate 4 where the first limit block 5 is installed. The second limit block 6 is parallel to the side of the support plate 4 where the first limit block 5 is installed, and the second limit block 6 extends along the length direction of the side of the support plate 4 where the first limit block 5 is installed. The length of the second limit block 6 is greater than the distance between the two hole seats 15 on the tool box. The side of the support plate 4 and its upper surface are provided with a plurality of bolt holes, and the positions of the first limit block 5 and the second limit block 6 can be adjusted according to needs to adapt to hole seats 15 of different sizes. The hole seat 15 is an L-shaped structure (the specific positioning method is as follows Figure 2 shown).

[0036] The length of the second limit block 6 is much larger than that of the first limit block 5. The first limit block 5 is used to contact the side wall of a hole seat 15, and the second limit block 6 is used to contact the ends of two hole seats 15 at the same time. The first limit block 5 is provided with one and cooperates with the second limit block 6. While ensuring positioning, it is convenient for the hole seat 15 to be hung on / removed from the workbench (if two first limit blocks 5 are relatively clamped on both sides of the two hole seats 15 as a whole, it is difficult to accurately adjust the distance between the two first limit blocks 5, and it is difficult to accurately hang the hole seat 15 between the two first limit blocks 5).

[0037] A parts box 13 is also fixedly mounted on the support plate 4 for placing the rivet heads 7 , so as to facilitate the selection and replacement of different rivet heads 7 according to different riveting requirements.

[0038] The cylinder 11 is used to drive the assembly of the rivet 16. The cylinder 11 is inverted and vertically arranged, and the telescopic rod of the cylinder 11 extends vertically downward. The bottom end of the telescopic rod of each cylinder 11 is detachably connected to a rivet head 7 through a connecting flange 8 to drive the rivet head 7 to move vertically, and then the tubular rivet 16 is riveted using the rivet head 7.

[0039] like Figure 3-Figure 4 As shown, the rivet head 7 includes two types. The head of the first type of rivet head 7 has a smooth surface, and the head of the second type of rivet head 7 contains a cross-shaped / X-shaped groove for riveting out different flanges.

[0040] like Figure 5 As shown, the tubular rivet 16 is a hollow rod-shaped part with a cap at one end. Figure 6 The flange is shown as being riveted out by the first type of rivet head 7. Figure 7 The figure shows a flange with a groove which is riveted out using a second type of rivet head 7 .

[0041] The rivet 16 can be fixed in the mounting hole of the hole seat 15 by riveting, so as to isolate the mounting hole of the hole seat 15 from direct contact with the bolt.

[0042] The specific working principle is:

[0043] First, select the rivet 16 of corresponding specifications according to the size of the mounting hole on the hole seat 15, and adjust the oil-water separator 3 according to the specifications of the rivet 16 to achieve a suitable working air pressure;

[0044] The positions of the first limiting block 5 and the second limiting block 6 are adjusted according to the sizes of the two hole seats 15 on the tool box, a rivet 16 is placed in each of the two mounting holes, and the tool box is hung on the workbench as a whole, so that the L-shaped hole seat 15 is hung on the support plate 4, and the first limiting block 5 is used to contact the side of one of the hole seats 15 to achieve positioning, and the second limiting block 6 is synchronously contacted with the ends of the two hole seats 15 to achieve positioning;

[0045] According to the positions of the mounting holes on the two hole seats 15, the position of the fixing plate 10 is adjusted accordingly so that the two cylinders 11 are respectively located directly above the corresponding mounting holes. A suitable rivet head 7 is selected and installed on the two cylinders 11. The tool box body 14 is held by hand and the pedal switch 2 is stepped on. The two cylinders 11 move downward synchronously to rivet and flanging the rivet 16. When the rivet 16 is assembled, the operator releases the pedal switch 3, the two cylinders 11 are reset, and the rivet head 7 returns to the initial position.

[0046] Through the above operation, the assembly of the rivets 16 on the two hole seats 15 can be completed quickly and accurately, which significantly improves the production efficiency and product quality. At the same time, the use of two cylinders 11 for synchronous riveting reduces the use of personnel, reduces the need for manual operation, and reduces labor intensity and safety risks.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
