[0002] The planetary shaft is an internal part of the car starter. The car planetary shaft is the shaft fixed on the planetary gear. Its function is to fix the planetary gear and transmit the power to the output shaft through the planetary shaft. At the same time, the planetary shaft also plays an important role in bearing torque, because when the planetary gear moves, the planetary shaft will bear the force and torque of the planetary gear. Therefore, the quality and strength of the planetary shaft will directly affect the stability and safety of the entire wheel reducer.

[0003] When installing the planetary carrier and the planetary shaft, the common practice is to use a hydraulic press to drive the planetary shaft to be inserted into the planetary carrier for fixation. However, during assembly, the hydraulic press can easily drive the planetary shaft to move, thereby causing the planetary carrier to deviate.

[0004] Therefore, a quick press-fitting tool for a planetary shaft of an automobile starter is proposed to solve the above-mentioned problems. Utility Model Content

[0023] Embodiment 1:

[0024] See also Figure 1-3 In this embodiment, a quick press-fitting tool for a planetary shaft of an automobile starter includes a bracket 1 and a planetary carrier 2. An auxiliary mechanism is provided in the bracket 1. The auxiliary mechanism includes a hydraulic cylinder 3 installed on the lower surface of the bracket 1, two connecting bolts 4 are threadedly connected to the upper surface of the bracket 1, a clamping mechanism 5 is arranged in the bracket 1, and an adjusting mechanism 6 is arranged in the bracket 1.

[0025] The clamping mechanism 5 includes a clamping box 51 fixedly installed between the brackets 1, a motor 52 fixedly installed on the right surface of the clamping box 51, a bidirectional screw 53 fixedly installed on the output end of the motor 52, an installation box 54 threadedly installed on the outer peripheral wall of the bidirectional screw 53, a rotating shaft 55 rotatably installed on the upper surface of the installation box 54, a clamping plate 56 fixedly installed on the outer peripheral wall of the rotating shaft 55, a slot 57 provided in the clamping plate 56 and a torsion spring 58 fixedly installed in the clamping plate 56. In order to increase the practicality of the rotating shaft 55, the rotating shaft 55 is located on the center line of the clamping plate 56, so that when the planetary carrier 2 is offset, the clamping plate 56 can be driven to rotate, thereby driving the rotating shaft 55 to rotate. After rotation, the rotating shaft 55 can be driven to reset by the torsion spring 58 in the clamping plate 56, and the planetary carrier 2 can be reset by resetting the rotation 55, thereby avoiding the offset of the planetary carrier 2 and the impact on assembly.

[0026] In this embodiment, the adjustment mechanism 6 includes a mounting rod 61 fixedly mounted on the lower surface of the bracket 1, a connecting box 62 slidably mounted on the lower surface of the mounting rod 61, and an electric push rod 63 fixedly mounted in the mounting rod 61. When the user needs to adjust the position of the hydraulic cylinder 3, the user starts the electric push rod 63 to drive the connecting box 62 to move, thereby changing the position of the hydraulic cylinder 3, so that the hydraulic cylinder 3 can assemble the planetary carrier 2 in different positions.

[0027] In this embodiment, the lower surface of the connection box 62 is fixedly connected to the hydraulic cylinder 3 , and the output end of the electric push rod 63 is fixedly connected to the connection box 62 .

[0028] It should be noted that the clamping box 51 is rotationally connected to the bidirectional screw 53 , and the installation box 55 is slidingly connected to the clamping box 51 , thereby limiting the movement of the installation box 55 .

[0029] In this embodiment, one end of the torsion spring 58 away from the clamping plate 56 is fixedly connected to the rotating shaft 55 , and the number of the torsion springs 58 is two.

[0030] In this embodiment, the clamping box 51 is located at the lower side of the hydraulic cylinder 3 , and bolt holes are provided in the bracket 1 .

[0031] In this embodiment, the planet carrier 2 and the clamping box 51 are movably connected, and a rubber layer is provided on the outer peripheral wall of the clamping groove 57 .

[0032] It should be noted that a controller is fixedly connected to the upper surface of the bracket 1 , and the controller is electrically connected to the hydraulic cylinder 3 and the motor 52 .

[0033] Embodiment 2:

[0034] See also Figure 1-3 On the basis of the first embodiment, a gasket is movably sleeved on the outer wall of the connecting bolt 4. By providing the gasket, the stability of the bracket 1 can be increased to prevent the bracket 1 from collapsing during use, thereby affecting the entire assembly.

[0035] The working principle of the above embodiment is:

[0036] The user first places the planetary carrier 2 into the clamping box 51, and then the user starts the motor 52 to drive the bidirectional screw 53 to rotate, and the bidirectional screw 53 drives the installation box 54 to move toward one end of the planetary carrier 2 until the installation box 54 drives the two clamping plates 56 to clamp the planetary carrier 2. Then the user starts the hydraulic cylinder 3, and the hydraulic cylinder 3 drives the planetary shaft to move downward for assembly. When the planetary carrier 2 is offset during assembly, it drives the clamping plate 56 to rotate, and the clamping plate 56 rotates to drive the torsion spring 58 to rotate. After rotation, the torsion spring 58 drives the rotating shaft 55 to reset, and the rotating shaft 55 drives the clamping plate 56 to reset, thereby completing the entire operation process.

[0037] The above beneficial effects are:

[0038] By setting a hydraulic cylinder, the hydraulic cylinder and the planetary shaft can be fixedly connected, and the planetary shaft and the planetary carrier can be connected by starting the hydraulic cylinder. By setting a motor, a bidirectional screw, a mounting box and a clamping plate, the clamping plate can be driven to clamp the planetary carrier. By setting a rotating shaft and a torsion spring, when the planetary shaft drives the planetary carrier to deviate, the rotating shaft drives the clamping plate to deviate. After the deviate, the torsion spring drives the clamping plate to reset to drive the planetary carrier to reset, thereby solving the problem that the hydraulic press easily drives the planetary shaft to move and thus drives the planetary carrier to deviate. By starting the electric push rod to drive the connecting box to slide on the lower surface of the mounting rod, the hydraulic cylinder can be driven to move to adapt to planetary carriers in different positions.

[0039] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
