[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] See Figures 1-5 A gear assembly and clamping mechanism for a brake actuator includes: a frame 1; a clamping linear module 43 mounted on the frame 1; a base gripper 421 mounted on the frame 1, capable of positioning and clamping a 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 a 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 using an elastic pressing structure, and finally a second pressing using a second pressing mechanism, flexible installation is achieved, preventing damage to the pinion 8 and the mounting shaft, and ensuring stable and reliable installation.

[0040] 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.

[0041] 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.

[0042] With the above structure, the gear is initially placed on the gear seat 9, then pressed for the first time by the elastic pressing structure, and then pressed for the second time by the second pressing mechanism, so as to achieve flexible installation without damaging the pinion 8 and the mounting shaft, and the installation is stable and reliable.

[0043] Example 2

[0044] In this embodiment, 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, the second pressing shaft 428 passing 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, and the second pressing cylinder 427 drives the second pressing shaft 428 to press the end face of the pinion 8, achieving the purpose of secondary pressing.

[0045] The brake actuator gear assembly and clamping mechanism comprises: a frame 1; 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 initially placing the gear on the gear seat 9, then performing a first pressing using an elastic pressing structure, and finally a second pressing using a second pressing mechanism, flexible installation is achieved, preventing damage to the pinion 8 and the mounting shaft, ensuring stable and reliable installation.

[0046] 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.

[0047] 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.

[0048] Multiple sets of second pressure shafts 428 are provided around the pinion 8, making the clamping more stable and reliable.

[0049] With the above structure, the gear is initially placed on the gear seat, then pressed for the first time by the elastic pressing structure, and then pressed for the second time by the second pressing mechanism, so as to achieve flexible installation without damaging the pinion and the mounting shaft, and the installation is stable and reliable.
