Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] To make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the attached drawings.

[0027] Please refer to Figures 1-4 As shown, this embodiment is a gear and ring pressing tooling, including:

[0028] Mounting structure, the mounting structure includes a mounting frame 11;

[0029] The mounting frame 11 is the main mounting carrier and provides structural stability through the contact of its lower end with the contact surface;

[0030] The mounting structure further includes an assembly block 12 and a movable opening 13. A set of the assembly blocks 12 are symmetrically clamped at the lower end of the mounting frame 11, and a set of the movable openings 13 are symmetrically formed at the upper end of the mounting frame 11;

[0031] The assembly block 12 can further ensure the structural stability by increasing the weight and the contact surface. The movable port 13 allows the gear ring to be press-fitted to move up and down.

[0032] The convenient feeding structure includes hole blocks 21, movable shafts 22, feeding frames 23, guiding rollers 24 and hydraulic push rods 25. Two groups of hole blocks 21 are symmetrically fixed at the middle ends on both sides of the mounting frame 11, and a movable shaft 22 is connected through the middle of the hole block 21. A feeding frame 23 is sleeved on the middle of the movable shaft 22, and guiding rollers 24 are rotatably connected at equal intervals on one side of the upper end of the feeding frame 23. Two groups of hydraulic push rods 25 are symmetrically fixed at the lower ends on both sides of the mounting frame 11, and the output end of the hydraulic push rod 25 is fixed to the lower end of the feeding frame 23.

[0033] The hole block 21 and the movable shaft 22 are used in cooperation to movably install the feeding frame 23. The feeding frame 23 and multiple guiding rollers 24 are used in cooperation to feed the gear ring to be press-fitted in a rolling manner. The hydraulic push rod 25 acts on the feeding frame 23 to complete the mechanical movement of the feeding frame 23.

[0034] It also includes a feeding structure, which includes electric push rods 41 and material placing frames 42. Two groups of electric push rods 41 are symmetrically fixed at the ends on both sides of the inner bottom end of the mounting frame 11, and a material placing frame 42 is fixed to the upper part of the output end of the electric push rod 41. Anti-slip lines are arranged at equal intervals on the upper end of the material placing frame 42.

[0035] The electric push rod 41 provides the power source for the up and down movement of the material placing frame 42. The material placing frame 42 and the anti-slip lines are used in cooperation to place the gear ring to be press-fitted and perform a preliminary positioning of the structure.

[0036] The feeding structure also includes support blocks 43, hydraulic cylinders 44 and rubber contact heads 45. Four groups of support blocks 43 are symmetrically fixed horizontally in the middle of the mounting frame 11, and a hydraulic cylinder 44 passes through the upper part of the support block 43. A rubber contact head 45 is fixed to the output end of the hydraulic cylinder 44.

[0037] The support block 43 installs and fixes the hydraulic cylinder 44. The hydraulic cylinder 44 provides the power source for the movement of the rubber contact head 45. By acting on the gear ring through the rubber contact head 45, its structure can be positioned.

[0038] Working principle: When performing feeding and press-fitting treatment on the gear ring, the gear ring to be press-fitted can be placed on the lower side of the upper part of the feeding frame 23 at a low position.

[0039] At this time, a diagonally upward force is applied to the feeding frame 23 through the controlled hydraulic push rod 25 until the horizontal angle of the area between the feeding frame 23 and the material placing frame 42.

[0040] Next, a driving force can be applied to the gear ring to be press-fitted. By using the rolling process of multiple guide rollers 24, the gear ring to be press-fitted can be easily and conveniently pushed onto the material placing rack 42. Then, a controlled electric push rod 41 applies an upward force to the material placing rack 42, passing through the movable opening 13 and between the rubber contact heads 45. Then, a controlled hydraulic cylinder 44 applies a force to the rubber contact heads 45 to act on the gear ring;

[0041] This solution can conveniently and labor-savingly complete the feeding of the gear ring. Feeding from a low position saves time and effort and reduces the operation risk, which helps to improve the feeding efficiency.

[0042] Please refer to Figures 1-4 As shown, based on the above embodiment, this embodiment further includes a positioning and determination structure. The positioning and determination structure includes a mounting block 31, an infrared distance sensor 32, and a buzzer 33. A set of the mounting blocks 31 are symmetrically and fixedly arranged at the upper end of the front surface of the mounting frame 11, and the infrared distance sensor 32 passes through the middle of the mounting block 31. One end of the infrared distance sensor 32 is sleeved with the buzzer 33;

[0043] The mounting block 31 mounts and fixes the infrared distance sensor 32. The infrared distance sensor 32 is used to detect the distance between it and the gear ring. The buzzer 33 generates a beep to prompt that the gear ring is accurately placed;

[0044] The infrared distance sensor 32 has a built-in control end and is electrically connected to the buzzer 33 through a wire;

[0045] Working principle: When the gear ring to be press-fitted is raised to between the rubber contact heads 45 as described above, the infrared distance sensor 32 can detect the distance between the two. When it is at the rated detection distance, the controlled buzzer 33 emits a beep for prompting, and then the rubber contact heads 45 are used for contact positioning;

[0046] When the buzzer 33 does not emit a beep, position deviation adjustment is required until a beep appears;

[0047] This solution can determine that the gear ring placed in this position is in the correct position, which is beneficial to improving the press-fitting accuracy and convenient for use.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
