[0045] The inner bottom surface of the clamp 105 is provided with the roller 10501, when the clamping position of the lifting arm 8 is adjusted, the friction between the lifting arm 8 and the inner bottom surface of the clamp 105 is reduced, the phenomenon that the lifting arm 8 is pulled and scratched and the paint is peeled off when sliding in the clamp 105 is avoided, and the assembly quality is effectively improved.

[0046] The second clamping assembly comprises the bearing plate 206; the front side of the workbench of the elevator 101 is provided with the bearing plate 206; the bearing plate 206 is driven to move upward to lift the turnover shaft 9 to a certain installation height.

[0047] The left and right sides of the upper surface of the base 3 are each provided with two first guide portions 3003, and the upper end of the bearing plate 206 is provided with the second guide portion 20601; the first guide portion 3003 and the second guide portion 20601 are both made of nylon material, and both are provided with arc surfaces that are flared outward, which is more beneficial to placing the main beam 7 and the turnover shaft 9 into the placing grooves on the base 3 and the bearing plate 206, avoiding scratching the main beam 7 and the turnover shaft 9 when they are placed, and ensuring the assembly quality.

[0048] The driving unit comprises a mounting frame 201, a transmission shaft 202, a second hand wheel 203, a gear 204, a connecting shaft 205, a second sliding rod 207 and a rack 208; the mounting frame 201 is fixed on the front side of the workbench of the elevator 101; the transmission shaft 202 is rotationally connected to the mounting frame 201; the second hand wheel 203 is fixed on the left end of the transmission shaft 202; the gear 204 is fixed on the right end of the transmission shaft 202 and located in the mounting frame 201; two connecting shafts 205 are fixed on the front side of the workbench of the elevator 101, the front ends of the two connecting shafts 205 penetrate through the bearing plate 206, and the front sides of the two connecting shafts 205 are provided with sliding holes 20501; one second sliding rod 207 is slidingly connected in each of the two sliding holes 20501, and the two second sliding rods 207 are connected with the bearing plate 206; the rack 208 is fixed on the rear side of the bearing plate 206 and engaged with the gear 204; the second hand wheel 203 is rotated to drive the gear 204 to rotate, thereby driving the bearing plate 206 provided with the rack 208 to move upward, and the turnover shaft 9 is lifted upward to the assembly height.

[0049] The specific process of assembling the hydraulic tail plate is as follows:

[0050] The assembly personnel first fix the main beam 7 on the base 3 by putting the two mounting plates 7001 in the middle of the main beam 7 into the positioning groove 3001, ensure the straightness of the center of the main beam 7 and the center of the assembly equipment, determine the only assembly center reference, then record the scale values of the mounting plates 7001 on the left and right sides of the main beam 7, control the manipulator 2 to move downward to the main beam 7 and clamp and fix the main beam 7, then control the manipulator 2 to lift the main beam 7 to a certain assembly height.

[0051] After the main girder 7 is fixed to the assembly height, the assembly personnel first put the turnover shaft 9 into the placing groove of the bearing plate 206, then loosen the clamp 105 on the workbench of the elevator 101, and then put the two lifting arms 8 into the clamp 105 for adjustment in the front-back direction. Since the inner bottom surface of the clamp 105 is provided with the roller 10501, the friction between the lifting arm 8 and the inner bottom surface of the clamp 105 can be reduced, so as to avoid the phenomenon that the lifting arm 8 is pulled and scratched and the paint is peeled off when sliding in the clamp 105, and the assembly quality is effectively improved. When adjusting the front-back position of the lifting arm 8, as shown in the figure, the positioning pin 5 in the positioning hole 4001 is inserted through the second mounting hole 8001 on the lifting arm 8, so as to realize that the center points of the second mounting hole 8001 and the first mounting hole 7002 are positioned on the same vertical line, and then the mounting position of the lifting arm 8 and the mounting plate 7001 on the main girder 7 is determined. At this time, the two clamps 105 are locked, and the two lifting arms 8 are fixed. The positioning pin 5 is pushed again, and the grease reservoir 6 on the positioning pin 5 is extruded to deform, so that part of the lubricating grease stored in the grease reservoir 6 is extruded from the grease outlet hole 5001 to the inner wall of the second mounting hole 8001. Another part of the lubricating grease is guided to the side surface of the lifting arm 8 along the first flow channel groove 5002 and the second flow channel groove 6001, which increases the lubricity of the second mounting hole 8001 on the lifting arm 8 and the side surface of the lifting arm 8, is beneficial to the installation of the lifting arm 8, and improves the assembly efficiency. Thereafter, the assembly personnel pull out the positioning pin 5 from the second mounting hole 8001. By recording the scale value on the base 3 when placing the main girder 7, the second scale line 10101 on the workbench of the elevator 101 is referred to, the first hand wheel 104 is rotated to drive the two clamps 105, and then the two lifting arms 8 are moved, so that the two lifting arms 8 are adjusted to the corresponding scale position. The two lifting arms 8 are lifted to the assembly height of the first mounting hole 7002 and the second mounting hole 8001 by controlling the elevator 101, and the installation work of the lifting arm 8 and the main girder 7 is carried out. It is not necessary to measure and align the installation position manually, which greatly improves the assembly efficiency.

[0052] After the installation of the lifting arms 8 and the main beam 7 is completed, the installation work of the turnover shaft 9 and the lifting arms 8 is carried out. Due to the variety of automobiles, the corresponding hydraulic tail plate specifications are different. For the hydraulic tail plate carried by the high-height carriage, the lifting arm 8 used is relatively long. Therefore, when installing the turnover shaft 9, the positions of the third mounting hole 8002 on the lifting arm 8 and the fourth mounting hole 9001 on the turnover shaft 9 are first corrected. The position correction process is as follows. The assembler rotates the second hand wheel 203 to drive the gear 204 to rotate, and then drives the bearing plate 206 on which the rack 208 is installed to move upward, so as to lift the turnover shaft 9 to the assembly height of the third mounting hole 8002 and the fourth mounting hole 9001. Then, the two clamps 105 are loosened. By controlling the extension of the mechanical arm 2 in the front-rear direction, the main beam 7 and the two lifting arms 8 are adjusted in the front-rear direction. After the third mounting hole 8002 on the lifting arm 8 and the fourth mounting hole 9001 on the turnover shaft 9 are aligned, the turnover shaft 9 is installed between the two lifting arms 8. Thus, the assembly work of the main beam 7, the lifting arms 8 and the turnover shaft 9 is completed. By rotating the second hand wheel 203 to drive the gear 204 to rotate, and then driving the bearing plate 206 on which the rack 208 is installed to lift the turnover shaft 9 upward for assembly, the working strength of lifting the turnover shaft 9 is reduced, the assembly efficiency is effectively improved, and the safety hazard of bruising the assembler caused by the falling of the turnover shaft 9 is eliminated.

[0053] Embodiment 2

[0054] On the basis of embodiment 1, as shown in Figure 14 , it further includes a collision simulation assembly. The collision simulation assembly includes a fixing frame 301 and a nylon plate 302. One fixing frame 301 is fixed to each of the two clamps 105. One nylon plate 302 is arranged on each of the two fixing frames 301. The nylon plate 302 has the same thickness as the lifting arm 8. The two nylon plates 302 are located directly above the two lifting arms 8. Since the mounting plate 7001 is fixed to the main beam 7 by manual welding, there is a welding error. During the process of lifting the lifting arm 8 upward to the position between the two mounting plates 7001 for installation, the nylon plate 302 located directly above the lifting arm 8 first passes between the two mounting plates 7001. If the distance between the two mounting plates 7001 is welded to be narrow, the nylon plate 302 collides with the mounting plate 7001. At this time, the assembler immediately stops the elevator 101 to avoid the collision between the lifting arm 8 and the mounting plate 7001, which may cause the lifting arm 8 to be bruised. Then, the main beam 7 with poor welding is replaced, and the subsequent assembly work is carried out. The nylon plate 302 is used for pre-collision simulation, which has a pre-protective effect on the lifting arm 8, and effectively ensures the assembly quality of the hydraulic tail plate.

[0055] Embodiment 3

[0056] On the basis of embodiment 1, as shown in Figure 1 ,Figure 2 and Figure 15 As shown in FIG. 3, the elevator 101 further comprises a protective cover 303 installed between the working table and the base 3 of the elevator 101. During the assembly process, the assembly personnel may put hands or legs into the lifting space of the elevator 101, and when the working table of the elevator 101 is lowered, there is a risk of crushing the assembly personnel. The lifting space of the elevator 101 is covered by the protective cover 303, effectively avoiding the assembly personnel from directly putting hands or legs into the elevator 101, and improving the safety factor of the assembly work.
