Technical Field

[0001] This utility model relates to the field of gear installation technology, and in particular to a gear press-fitting fixture. Background Technology

[0002] Gear rings are key components in mechanical transmissions, used to transmit motion and power in mechanical devices. A gear is a mechanical component with teeth on its rim, transmitting motion and power through the meshing of its teeth. Currently, gear installation mainly involves pressing the gear onto the shaft using external pressure. However, existing press-fitting fixtures are simple in structure and inconvenient for adjusting and using gears of different specifications, causing inconvenience in use. Utility Model Content

The support mechanism is equipped with a limiting mechanism for limiting and fixing the mounting shaft, and a pressing mechanism for pressing the gear is set on the upper side of the limiting mechanism. The pressing mechanism includes guide columns vertically arranged on both sides of the limiting mechanism. A lifting plate is set on the guide columns. A connecting frame is fixed to the upper end of the lifting plate. A hydraulic telescopic rod connected to the connecting frame is fixed on the support frame. The lower end face of the lifting plate is set into a groove. A rotating plate is set in the groove. A worm gear is set on the outer ring of the rotating plate. A worm gear is installed on the lifting plate. A fixed plate is installed at the lower end of the lifting plate. A through hole is opened at the center of the lifting plate, the rotating plate, and the fixed plate. An arc-shaped groove is opened on the circumference of the rotating plate. A vertical groove opposite to the arc-shaped groove is opened on the circumference of the fixed plate. A pressure column is set in the vertical groove and the arc-shaped groove. The lower end of the pressure column passes through the fixed plate.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a gear pressing fixture includes a support mechanism, which includes a base plate 11, a support frame 12 fixed to the rear side of the upper end of the base plate 11, a limiting mechanism for limiting and fixing the mounting shaft, and a pressing mechanism for pressing the gear on the upper side of the limiting mechanism.

[0025] In this embodiment: the limiting mechanism includes a limiting cylinder 21 fixed to the upper end face of the base plate 11. Two supporting flanges 22 are provided on the outer diameter of the limiting cylinder 21. Top posts 23 are evenly distributed on the limiting cylinder 21 between the supporting flanges 22. A clamping plate 24 is fixed to each top post 23 through the inner end face of the limiting cylinder 21. A flange ball is provided at the other end of each top post 23, and a spring 25 is sleeved on one side of the flange ball on the top post 23 to facilitate the outward movement and reset of the top post 23. Rotatably connected to the supporting flanges 22... There is a rotating ring 26, and a rotating rod is fixed on the outer diameter of the rotating ring 26. A boss 27 opposite to the flange ball is provided on the inner wall of the rotating ring 26. The top post 23 is slidably connected to the limiting cylinder 21, and the boss 27 is slidably connected to the flange ball at the end of the guide post 31. The mounting shaft is placed vertically in the limiting cylinder 21, and the rotating ring 26 is rotated, so that the boss 27 in the rotating ring 26 squeezes and pushes the top post 23. The clamping plate 24 at the end of the top post 23 clamps and fixes the mounting shaft.

[0026] In this embodiment: the pressing mechanism includes guide columns 31 vertically arranged on both sides of the limiting mechanism. A lifting plate 34 is provided on the guide columns 31. A connecting frame 33 is fixed to the upper end of the lifting plate 34. A hydraulic telescopic rod 32 connected to the connecting frame 33 is fixed on the support frame 12. A hydraulic pump station and control system are connected to the hydraulic telescopic rod 32 through hydraulic pipes. The hydraulic pump station and control system are existing technologies known to those skilled in the art and will not be described in detail here. The lower end face of the lifting plate 34 is set in a groove shape. A rotating plate 35 is provided in the groove. A worm gear is provided on the outer ring of the rotating plate 35. A worm gear 36 is installed on the lifting plate 34. A fixed plate 37 is installed at the lower end of the lifting plate 34. A through hole is opened at the center of the lifting plate 34, the rotating plate 35 and the fixed plate 37. An arc-shaped groove is opened on the circumference of the rotating plate 35. A vertical groove opposite to the arc-shaped groove is opened on the circumference of the fixed plate 37. A pressure column 38 is provided, with its lower end passing through a fixed plate 37. A lifting plate 34 is slidably connected to a guide column 31, a rotating plate 35 is rotatably connected to the lifting plate 34, and a worm gear 36 is rotatably connected to the lifting plate 34. The worm gear 36 meshes with the worm teeth on the outer ring of the rotating plate 35. The pressure column 38 is slidably connected to the rotating plate 35 and the fixed plate 37. The axis of the limiting cylinder 21 coincides with the axis of the lifting plate 34, the rotating plate 35, and the fixed plate 37. By rotating the worm gear 36 and meshing with the worm teeth on the outer ring of the rotating plate 35, the rotating plate 35 is driven to rotate. This causes the arc-shaped groove of the rotating plate 35 to push the pressure column 38 to adjust its relative center position under the vertical groove limit of the fixed plate 37. The pressure column 38 is adjusted to a pressing and pushing position suitable for gears of different specifications. Then, the hydraulic telescopic rod 32 extends and pushes the connecting frame 33 and the lifting plate 34 as a whole to move downward under the limit of the guide column 31. The gear is pressed by the pressure column 38.

[0027] The working principle and usage process of this utility model are as follows: The mounting shaft is placed vertically inside the limiting cylinder 21, and the rotating ring 26 is rotated, so that the boss 27 inside the rotating ring 26 presses and pushes the top column 23. The clamping plate 24 at the end of the top column 23 clamps and fixes the mounting shaft. The gear is sleeved on the mounting shaft, and the rotating worm gear 36 meshes with the worm gear on the outer ring of the rotating disk 35, driving the rotating disk 35 to rotate. The arc-shaped sliding groove of the rotating disk 35 pushes the pressure column 38 to adjust its relative center position under the vertical sliding groove limit of the fixed disk 37. The pressure column 38 is adjusted to the pressing and pushing position to adapt to different specifications of gears. Then, the hydraulic telescopic rod 32 extends and pushes the connecting frame 33 and the lifting disk 34 to move downward under the limit of the guide column 31, pressing the gear onto the mounting shaft.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
