[0032] A transplanting track 1 is arranged between the engine 2 positioning brackets 1, a transplanting trolley 4 is arranged to slide along the transplanting track 1, a lifting scissors 41 is arranged on the transplanting trolley 4, a lifting plate 42 is arranged on the lifting scissors 41, a plurality of universal balls 43 are fixedly installed on the lifting plate 42, a floating tray 44 is placed above the universal balls 43, two rows of receiving bosses 45 are symmetrically arranged on the floating tray, and an oil pan 5 is placed on the receiving bosses 45.

[0033] The device adopts a transfer trolley 4 with a servo lifting function, which carries the oil pan 5 and automatically moves it to the pre-assembly bottom of the engine 2. The pre-assembly of the engine 2 is positioned and supported by a fixed bracket. The oil pan 5 is raised to a set position according to the product model. After the oil pan 5 is raised, the joint surface of the oil pan 5 and the engine 2 is basically fitted, and then the bolts are manually tightened.

[0034] Reference Figure 4A threaded hole 14 is provided on the adjusting plate 11, a docking plate 15 is provided below the supporting column 12, a threaded hole 14 is provided on the docking plate 15, the docking plate 15 fixes the supporting column 12 on the adjusting plate 11 through a stud, the length of the adjusting plate 11 is greater than the length of the docking plate 15, the engine positioning bracket is used for supporting and positioning the engine 2, the positioning of the engine 2 is realized by a plurality of supporting columns 12, in order to adapt to different lengths of the engine 2, the supporting column 12 can be disassembled and installed at other positions of the adjusting plate 11 corresponding to the threaded hole 14.

[0035] Support columns 12 are fixedly mounted on both sides of the adjustment plate 11 , and positioning plates 13 are mounted on the support columns 12 .

[0036] Reference Figure 5 An electric control box 46 is fixedly installed at one end of the transplanting trolley 4, and a driving motor is installed in the electric control box 46. The electric control box 46 is installed with a control panel. The driving motor adopts an existing servo motor. The lifting scissors fork 41 adopts the existing lifting scissors fork 41 structure. By pushing the push rod at the lower end of the lifting scissors fork 41, the lifting plate 42 of the lifting scissors fork 41 is lifted and lowered. An armrest 48 is fixedly installed on the outside of the electric control box 46 and on the transplanting trolley. The armrest 48 can be manually pushed to transport the transplanting trolley from the gluing station to the assembly station 6.

[0037] Rollers 49 are arranged below the transplanting trolley 4 , and the rollers 49 are in contact with the bottom surface of the transplanting track 1 . Four rollers 49 are arranged below the transplanting trolley 4 .

[0038] Limiting bosses 31 are arranged on both sides of the transplanting track 1, and guide wheels 410 are arranged on both sides of the transplanting trolley 4. The guide wheels 410 are in contact with the inner side walls of the limiting bosses 31. The arrangement of the guide wheels 410 ensures that the transplanting track 1 can move along a straight line during the forward movement.

[0039] A step 411 is provided on the receiving boss 45, and the oil pan 5 is placed on the step 411. The step 411 provided on the receiving boss 45 can be engaged with the lower side corner of the oil pan 5. The receiving boss 45 is arranged in two rows, and the steps 411 of the two rows of receiving bosses 45 are arranged opposite to each other. Each row can use three steps, and multiple receiving bosses 45 can simultaneously receive the oil pan 5.

[0040] Stoppers 412 are evenly distributed around the lifting plate 42 , and the floating tray 44 is disposed between the stoppers 412 . The stoppers 412 restrict the floating tray 44 within a movable area surrounded by the stoppers 412 .

[0041] An adjustment handle 413 is provided on the floating tray 44. When the floating tray 44 needs to be adjusted to align the oil pan 5 and the engine 2, the handle 413 is held to push the floating tray 44 to slide on the universal ball 43, thereby avoiding the safety hazard of the lifting chain 8 breaking when adjusting the lifting chain 8.

[0042] Reference Figure 3The area between the engine 2 positioning brackets 1 is the assembly station 6, the transfer track 1 is extended away from the assembly station 6, and the area where the transfer track 1 is extended is the oil pan gluing station 7.

[0043] The operation process of the device is as follows: the initial position of the transplanting trolley 4 is at the oil pan gluing station 7, the engine 2 is pre-assembled and hoisted onto the engine 2 positioning bracket 1 manually, and is placed stably according to the posture requirements, and then the oil pan 5 is hoisted onto the receiving boss 45 on the floating tray 44 of the transplanting trolley 4, and the bottom side of the oil pan 5 falls on the step 411 of the receiving boss 45. At this time, the lifting scissors 41 of the transplanting trolley 4 is lowered to the initial position, and glue is manually applied on the joint surface of the oil pan 5. After the gluing is completed, the transplanting device is started, and the transplanting trolley 4 is transported to the assembly station 6 with the oil pan 5, and the control panel is manually operated to lift the oil pan 5 to the specified position according to the product model. At this time, there is a gap of about 1-2mm between the oil pan 5 and the joint surface of the engine 2, and the lifting stroke of the lifting scissors 41 is 0-500mm;

[0044] The handle 413 is manually held to push the floating tray 44 to move horizontally on the universal ball 43, so as to align the screw holes of the oil pan 5 and the engine 2. The floating tray 44 is limited by baffles around the lifting plate 42. The distance between the baffle and the floating tray 44 is 20 mm, so as to ensure sufficient floating amount. After alignment, the bolts are tightened one by one.

[0045] After the assembly is completed, the lifting scissors 41 is lowered, the engine 2 is manually lifted off the device, and the transplanting trolley 4 returns to the initial position. The safety of the entire assembly process is greatly improved, the labor intensity is reduced, and the operation assistance time is shortened.

[0046] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
