[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] See Figures 1-14 An automotive brake actuator gear assembly device comprises: a frame 1; a conveying mechanism 2, mounted on the frame 1, capable of conveying a tooling plate for positioning the workpiece; an assembly clamping mechanism 4, mounted on the frame, capable of clamping and assembling a pinion; an oiling mechanism, mounted on the frame, capable of applying oil to a large gear; and a floating mechanism 3, mounted on the frame, capable of clamping and assembling a large gear. The conveying mechanism has a conveyor line on which the tooling plate can be conveyed. It can automatically install the large and small gears. During installation, both the large and small gear mechanisms are in a floating state, facilitating the large and small gears to find a suitable meshing position for installation and avoiding damage to the gears caused by forced installation.

[0073] The assembly clamping mechanism 4 includes: a clamping linear module 43, mounted on the frame 1; a base gripper 421, mounted on the frame 1, capable of positioning and clamping the gear seat 9; a clamping mechanism 41, mounted on the slider of the clamping linear module 43, capable of clamping the gear seat 9 and the pinion 8; and a pressing mechanism 42, mounted on the slider of the clamping linear module 43, capable of pressing the pinion 8 onto the gear seat 9. By first initially placing the gear on the gear seat 9, then performing a first pressing through an elastic pressing structure, and then a second pressing through a second pressing mechanism, flexible installation is achieved, preventing damage to the pinion 8 and the mounting shaft, ensuring stable and reliable installation.

[0074] The clamping mechanism 41 has a movable plate 411, which is mounted on the slider of the linear module. A clamping lifting cylinder 412 is mounted on the movable plate 411, and a clamping cylinder 413 is mounted on the piston rod of the clamping lifting cylinder 412. The clamping cylinder 413 has grippers that can clamp the gear seat 9 and the pinion 8. The linear module drives the grippers to clamp the gear seat 9, placing it onto the base grippers 421. Then, the grippers clamp the pinion 8, initially placing it onto the mounting shaft of the gear seat 9.

[0075] The clamping mechanism 42 includes: a first clamping cylinder 422 mounted on a movable plate 411; a clamping slide 423 connected to the piston rod of the first clamping cylinder 422; a clamping base plate 424 mounted on the bottom of the clamping slide 423; a pressure plate 425 connected to the clamping base plate 424 by a spring; and a first pressure shaft 426 mounted on the pressure plate 425, which can press the center hole of the pinion 8. The first clamping cylinder 422 drives the clamping base plate 424 downward, and the pressure plate 425 and the first pressure shaft 426 on the clamping base plate 424 press the center hole of the pinion 8. Because there is a spring between the clamping base plate 424 and the pressure plate 425, the first pressing is a flexible pressing, which will not damage the pinion 8 and the mounting shaft.

[0076] A second pressing mechanism is also provided. The second pressing mechanism 42 includes: a second pressing cylinder 427, mounted on a pressing slide 423; and a second pressing shaft 428 connected to the piston rod of the second pressing cylinder 427, which passes through the pressing base plate 424 and the pressure plate 425. The second pressing shaft 428 can press the end face of the pinion 8. After the first flexible pressing, the second pressing mechanism 42 achieves rigid pressing, using the second pressing cylinder 427 to drive the second pressing shaft 428 to press the end face of the pinion 8, thus achieving the purpose of secondary pressing.

[0077] By first placing the gear on the gear seat 9, then pressing it for the first time through the elastic pressing structure, and then pressing it for the second time through the second pressing mechanism, flexible installation is achieved, which will not damage the pinion 8 and the mounting shaft, and the installation is stable and reliable.

[0078] The floating mechanism 3 includes: an upper floating mechanism 31, mounted on the frame 1, which can movably install the large gear 7 into the housing 6; and a lower floating mechanism 32, mounted on the frame 1, which can drive the gear seat 9 and the small gear 8 to move when installing the large gear 7. During the installation of the large gear 7, both the large gear 7 and the small gear 8 can be in a floating state, facilitating the large gear 7 and the small gear 8 to find a suitable meshing position for installation and avoiding damage to the gears caused by forced installation.

[0079] The conveying mechanism 2 has a conveying line 21, and the tooling plate 22 can be conveyed on the conveying line, which plays the role of conveying the tooling plate 22. When assembly is required, it is sent into the assembly position and sent out after the assembly is completed.

[0080] The floating mechanism 31 includes: a robotic arm 311; an upper lifting cylinder 312 mounted on the frame 1; an upper sliding seat 313 connected to the piston rod of the upper lifting cylinder 312; a sliding claw 314 movably mounted on the upper sliding seat 313; an upper mounting base 315 connected to the sliding claw 314; and a suction mechanism mounted on the upper mounting base 315, capable of adsorbing gears. The robotic arm 311 drives the entire mechanism to move, and the upper lifting cylinder 312 drives the large gear 7 to rise and fall, thus sending it into the assembly position. The sliding claw 314 is movably mounted to the upper sliding seat 313, allowing for movement and enabling the suction mechanism to operate. When the large gear 7 is sent into the housing 6, the large gear 7 can move within a small range to find a suitable meshing position, inserting into the small gear 8 and meshing with it, avoiding damage to the gear caused by forced installation. The suction mechanism is a suction cup 316, which serves to adsorb the gears.

[0081] The lower floating mechanism 32 includes: a lower lifting cylinder 321 mounted on the frame 1; a lower lifting seat 322 connected to the piston rod of the lower lifting cylinder 321; a lower push rod 323, with its first end mounted on the lower lifting seat 322 and its second end passing through the bottom plate of the frame 1; and a lower top plate 326 connected to the lower push rod 323, capable of lifting the tooling plate 22 and detaching it from the conveyor line 21. The lower lifting cylinder 321 drives the lower lifting seat 322 to move, thereby driving the lower push rod 323 to rise and fall, which in turn drives the lower top plate 326 to rise and fall. The lower top plate 326 lifts the tooling plate 22 and detaches it from the conveyor line 21 for subsequent assembly work.

[0082] When installing the large gear 7, both the large gear 7 and the small gear 8 mechanism can be in a floating state, which makes it easy for the large gear 7 and the small gear 8 to find a suitable meshing position for installation, avoiding the problem of damage to the gears caused by forced installation.

[0083] During the working process, the clamping mechanism of the assembly clamping mechanism first clamps the gear seat onto the base jaws for positioning. Then, the clamping mechanism of the assembly clamping mechanism clamps the small gear onto the gear seat for initial positioning. The first clamping mechanism of the pressing mechanism clamps the small gear for the first time, and then the second clamping mechanism clamps the small gear again. After the small gear is assembled, the upper floating mechanism puts the small gear assembly into the housing. The upper floating mechanism then clamps the large gear, first applies oil to the oiling tank, and then puts the large gear into the housing to mesh with the small gear. The assembly work is then completed.

[0084] The above structure enables automatic installation of the large and small gears. During installation, both the large and small gear mechanisms are in a floating state, which facilitates the large and small gears to find the appropriate meshing position for installation and avoids damage to the gears caused by forced installation.
