In the prior art, the mounting sleeve is usually riveted into the side beam of the battery tray by employees using handheld pneumatic or electric riveting machines. However, this method has low production efficiency. Due to the manual riveting, the yield rate after riveting is also uneven, which will cause the battery tray to be unable to be stably installed on the vehicle body. Summary of the invention

[0027] The present invention is further described below in conjunction with embodiments and drawings.

[0028] like Figure 5 As described above, the battery tray sleeve riveting equipment is mainly used to rivet the sleeve 18 in the figure to the inside of the sleeve mounting hole 17a, wherein the sleeve mounting hole 17a is formed on the side beam 17, and the side beam 17 is fixedly installed in the circumference of the battery tray 16.

[0029] like Figures 1 to 3As shown, a battery tray sleeve riveting device includes a base 1 and a workbench 2 slidably arranged along the length direction thereof, a fixing component is installed on the top of the workbench 2, which is used to fix the battery tray 16 on the workbench 2, a mounting frame 3 is installed at one end in the length direction of the base 1, and a riveting system A is installed on the top of the mounting frame 3, the riveting system A has a plurality of upper pressing blocks 5 that can move up and down simultaneously, and lower pressing blocks 6 are distributed on the workbench 2. When the workbench 2 slides to one side to below the riveting system A, each upper pressing block 5 can be opposite to each lower pressing block 6 in the vertical direction. After the battery tray 16 is fixedly installed on the workbench 2, each sleeve mounting hole 17a is opposite to the lower pressing block 6. After the sleeve 18 is placed in the sleeve mounting hole 17a, the riveting system A drives the upper pressing block 5 to move downward, so that the sleeve 18 can be riveted into the corresponding sleeve mounting hole 17a. A data monitoring component is installed on the mounting frame 3. The data monitoring component is equipped with a pressure sensor 7 and a stroke sensor 8. The pressure sensor 7 is used to monitor the pressure applied by the riveting system A, and the stroke sensor 8 is used to monitor the riveting stroke of the riveting system A.

[0030] The fixing assembly can ensure that the battery tray 16 will not shake during riveting, and the riveting system A can then simultaneously rivet each sleeve 18 downward, greatly increasing the overall riveting efficiency of the battery tray 16. The design of the lower pressing block 6 can facilitate the positioning and installation of the battery tray 16, and can also support the battery tray during riveting. The data monitoring assembly can monitor the riveting system A, thereby ensuring that each sleeve 18 can be well riveted in the sleeve mounting hole 17a.

[0031] like Figure 1 and Figure 2 As shown, the riveting system A includes hydraulic cylinders 4 distributed on the top of the mounting frame 3, and the upper pressure block 5 is fixedly installed at the bottom of the hydraulic cylinder 4. In this embodiment, fourteen hydraulic cylinders 4 are fixedly installed on the top of the mounting frame 3, and each hydraulic cylinder 4 corresponds to a sleeve mounting hole 17a on the side beam 17.

[0032] In this embodiment, the hydraulic cylinder 4 adopts the design of a bidirectional hydraulic cylinder, which includes a cylinder seat 4a fixedly mounted on the top of the mounting frame 3 and a cylinder rod 4b vertically arranged on the cylinder seat 4a, an upper pressure block 5 fixedly mounted on the lower end of the cylinder rod 4b, a pressure sensor 7 arranged between the cylinder rod 4b and the upper pressure block 5, a stroke sensor 8 arranged on the side of the cylinder seat 4a and vertically mounted on the top of the mounting frame 3, a limit bracket 4c fixedly mounted on the top of the cylinder rod 4b, and when the cylinder rod 4b moves downward, the limit bracket 4c can press the stroke sensor 8 downward. With such a design, when the hydraulic cylinder 4 is riveted downward, the force applied downward by the hydraulic cylinder 4 and the distance moved downward can be monitored, thereby ensuring that each sleeve 18 is stably riveted in the sleeve mounting hole 17a.

[0033] like Figure 1 As shown, the data monitoring component also includes a PLC module 9 and a monitoring panel 10. The pressure sensor 7, the stroke sensor 8 and the monitoring panel 10 are all electrically connected to the PLC module 9. The data measured by the pressure sensor 7 and the stroke sensor 8 can be collected and converted by the PLC module 9 and finally displayed on the monitoring panel 10. In addition, the data collected by the PLC can be directly uploaded to the system through a network cable and can be detected in real time using a mobile device. With this design, it is possible to more intuitively observe whether each sleeve 18 is stably riveted in the sleeve mounting hole 17a, thereby ensuring the overall yield after riveting.

[0034] like Figure 4 As shown, the fixing component is a telescopic cylinder 11 vertically mounted on the top of the workbench 2, and a pressing block 11a is fixedly mounted on the end of the cylinder rod of the telescopic cylinder 11. When the telescopic cylinder 11 is driven, the pressing block 11a can press the battery tray 16 downward so that the battery tray 16 is closely attached to the surface of the workbench 2. In this embodiment, a total of six telescopic cylinders 11 are provided, and the six telescopic cylinders 11 are symmetrically distributed in pairs at both ends of the sliding direction of the workbench 2. Such a design can ensure that the battery tray 16 is stably fixed on the top of the workbench 2.

[0035] In this embodiment, a positioning pin 12 is fixedly installed on the top of the workbench 2, and a positioning hole 17b is formed on the side beam 17. When the battery tray 16 is placed on the workbench 2, the positioning pin 12 can be inserted into the positioning hole 17b. Such a design can facilitate the placement of the battery tray 16, and can also further avoid the position deviation of the battery tray 16 during riveting, which affects the riveting quality.

[0036] like Figure 2 As shown, four slide rails 13 are fixedly installed on the top of the base 1 along its length direction, and a slider 14 is fixedly installed on each slide rail 13. The workbench 2 is fixedly installed on the top of the slider 14. A cylinder 15 arranged along its length direction is also fixedly installed on the top of the base 1. The cylinder rod end of the cylinder 15 is fixedly installed on the workbench 2. With this design, the workbench 2 can slide on the base 1.

[0037] Based on the above-mentioned riveting equipment, the riveting method of the battery tray sleeve specifically includes the following steps:

[0038] Step 1: Place the battery tray 16 on the top of the workbench 2, wherein each pressing block 6 is correspondingly inserted into the sleeve mounting hole 17a, and each positioning pin 12 is correspondingly inserted into the positioning hole 17b.

[0039] Step 2: Drive each telescopic cylinder 11 so that the pressing block 11 a presses the battery tray 16 downward, so that the battery tray is fixedly mounted on the top of the workbench 2 .

[0040] Step 3: Place the sleeve 18 on the upper end of each sleeve mounting hole 17a.

[0041] Step 4: Drive the cylinder 15 to slide the workbench 2 to the position directly below the riveting system A.

[0042] Step 5: Drive each cylinder rod 4b to move vertically downward so that each sleeve 18 is synchronously riveted into the corresponding sleeve mounting hole 17a.

[0043] Step 6: During the downward riveting process in step 5, the pressure sensor 7 and the stroke sensor 8 perform real-time data detection and transmit the detected data to the monitoring panel 10 or a mobile device, so that the operator can monitor whether each sleeve 18 is qualified for riveting, thereby ensuring the yield rate of riveting.

[0044] Step 7: Finally, drive the cylinder 15 to slide the workbench 2 to the initial position, and take out the battery tray 16 to complete the entire riveting process.

[0045] Through the above steps, the battery tray can be quickly sleeve-riveted, which greatly speeds up the overall riveting efficiency of the battery tray 16 and is also very convenient to operate.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
