[0038] The end face where the front housing 1 connects to the main housing is designated as the main housing connection surface 14, such as... Figure 1 As shown.
[0039] An automatic gearbox assembly closing method, including
[0040] Multiple clamping process pin holes are provided on the outer wall of the front housing 1, such as the first front housing pin hole 11, the second front housing pin hole 12, and the third front housing pin hole 13; the axes of the multiple clamping process pin holes are in the same horizontal plane and parallel to the main housing connecting surface 14. For different models of front housing 1, the distance between the plane where the axes of the clamping process pin holes are located and the main housing connecting surface 14 is the same, which is the same value. When the gripper 7 clamps the front housing 1, the descent height is also a fixed value, which is convenient for control.
[0041] When closing the boxes,
[0042] The main shell connecting surface 14 of the former housing 1 is used as the positioning surface, and the positioning method is two pins on one surface; it is placed on the positioning seat 25 of the lifting platform 2;
[0043] After the gripper 7 descends to its position, the gripper 7 engages with the clamping process pin hole to clamp the front housing 1; the gripper 7 then transports the front housing 1 to the box assembly station.
[0044] After the main shell is conveyed to the box assembly station by the main shell conveyor 6, glue is applied to the box assembly surface of the main shell. The glue application detection device 4 is used to take pictures to check whether the glue application is qualified, including whether the glue line is broken and whether the thickness meets the requirements. After the glue application is qualified, the front shell and the glued main shell are assembled and bolts are installed and tightened.
[0045] like Figure 2 As shown, the automatic gearbox assembly closing equipment that implements the above method includes grippers 7, a lifting platform 2, a translation track 3, an adhesive application detection device 4, an adhesive application device 5, and a main housing conveying device 6. The lifting platform 2 is used to load the front housing 1 onto the line and lift the front housing 1 to the gripping position of the grippers 7; the grippers 7 grip the front housing 1 and move it along the translation track 3 to the closing station; the adhesive application device 5 is used to apply adhesive to the closing surface of the main housing, and the adhesive application detection device 4 takes pictures and detects the adhesive application quality; the main housing conveying device 6 connects the closing station and its upstream and downstream stations to convey the main housing.
[0046] The structures of the translation track 3, the glue application detection device 4, the glue application device 5, and the main shell conveying device 6 are existing technologies and will not be described in detail here.
[0047] like Figure 3 , Figure 4 and Figure 5As shown, the gripper 7 includes a mounting plate 706, which is mounted on a translation track 3 and can be raised and lowered relative to the translation track 3, or can be translated along the translation track 3. For example, the mounting plate 706 is connected to a slider of the translation track 3 via a lifting cylinder, and the slider is translated under the drive of the translation cylinder. A slide rail 712 is provided on the lower side of the mounting plate 706, and a first support arm 701 and a second support arm 703 are slidably mounted on the slide rail 712. A gripping cylinder 705 is provided between the first support arm 701 and the second support arm 703. Specifically, the housing of the gripping cylinder 705 is fixed to the first support arm 701, and the piston rod is fixedly connected to the second support arm 703. By controlling the gripping cylinder 705, the distance between the first support arm 701 and the second support arm 703 can be controlled to realize the gripping or release of the front housing 1.
[0048] Furthermore, to limit the clamping position, the mounting plate 706 is also provided with a first buffer block 708, a second buffer block 709, a first stop 710, and a second stop 711. In the extending direction of the slide rail 712, the first buffer block 708, the first stop 710, the second stop 711, and the second buffer block 709 are arranged sequentially at intervals. The first support arm 701 is located between the first buffer block 708 and the first stop 710, and the second support arm 703 is located between the second stop 711 and the second buffer block 709. The first buffer block 708 and the second buffer block 709 respectively limit the outer positions of the first support arm 701 and the second support arm 703, while the first stop 710 and the second stop 711 respectively limit the inner positions of the first support arm 701 and the second support arm 703.
[0049] The inner side of the first support arm 701 is provided with a first pin 702 and a second pin 707, and the inner side of the second support arm 703 is provided with a third pin 704. In the direction perpendicular to the slide rail 712, the first pin 702, the third pin 704, and the second pin 707 are arranged alternately to achieve the clamping of the front housing 1. Of course, the positions of the first pin 702, the third pin 704, and the second pin 707 can also be designed and selected according to design requirements.
[0050] To accommodate different models of the front housing 1, the first pin 702 and the second pin 707 are modularly integrated and mounted on a quick-change template, which is detachably connected to the first support arm 701. When the clamping process pin holes on the front housing 1 need to be adjusted, the module consisting of the first pin 702, the second pin 707, and the quick-change template is replaced accordingly.
[0051] The lifting platform 2 includes a fixed bracket 21, which is fixed to the frame or the ground. A lifting cylinder 22 and a support platform 24 are mounted on the fixed bracket 21. The support platform 24 is connected to the fixed bracket 21 via a guide rail assembly 23. The housing of the lifting cylinder 22 is fixed to the fixed bracket 21, and the piston rod is connected to the support platform 24. Driven by the lifting cylinder 22, the support platform 24 can rise and fall relative to the fixed bracket 21. A positioning seat 25 is provided on the support platform 24, and a short bolt detection head 26 is provided on the positioning seat 25.
[0052] When the automatic gearbox assembly closing equipment is working...
[0053] Take the front housing 1, clean the main housing connecting surface 14 with wiping paper, and place it on the positioning seat 25;
[0054] Take two short, flower-shaped box bolts (M8x1.25x25 M8 socket head cap screws) and place them into the corresponding bolt holes 15 of the front housing 1.
[0055] After the short bolt inspection head 26 inspects and confirms that the bolt assembly is complete, the gripper 7 moves down to the gripping position. At this time, the first pin 702, the third pin 704, and the second pin 707 correspond to the third front housing pin hole 13, the second front housing pin hole 12, and the first front housing pin hole 11, respectively. The gripping cylinder 705 retracts, and the first pin 702, the third pin 704, and the second pin 707 are inserted into the third front housing pin hole 13, the second front housing pin hole 12, and the first front housing pin hole 11, respectively, completing the clamping.
[0056] Control the gripper 7 and the front housing 1 to move along the translation track 3 to the box closing station;
[0057] After the main shell is conveyed to the box-closing station by the main shell conveying device 6, the gluing device 5 applies glue to the box-closing surface of the main shell.
[0058] After the adhesive coating detection device 4 confirms that the adhesive coating is qualified, the gripper 7 releases the front housing 1, completing the closing of the main housing and the front housing 1.
[0059] Install the box bolts to complete the box assembly operation.
