[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] like Figure 1 As shown, this embodiment provides a steering bearing bending device, including a loading platform 1, a pressing mechanism 2, and a lifting block 3.

[0024] Specifically, Figure 1 As shown, the loading platform 1 is in the shape of a rectangular plate and is arranged horizontally, where horizontal means parallel to the placement surface of the device.

[0025] Specifically, Figure 1 and Figure 2 As shown, the pressing mechanism 2 includes a clamping table 21 and a pressing table 22 arranged on the upper surface of the loading platform 1. The clamping table 21 is in the shape of a rectangular plate, and two clamping strips 23 with adjustable spacing are arranged on its upper surface. The clamping table 21 is movably arranged along the length direction of the clamping strip 23, and the pressing table 22 is arranged on the moving path of the clamping table 21, and a pressing surface 24 is vertically arranged thereon, and the vertical direction refers to the direction perpendicular to the placement surface of the device; the pressing surface 24 is perpendicular to the clamping strip 23, and one end of the clamping strip 23 facing the pressing surface 24 is flush with a side of the clamping table 21 facing the pressing surface 24.

[0026] Specifically, Figure 1~Figure 3 As shown, there are two lifting blocks 3, which are symmetrically arranged on both sides of the pressing platform 22 and are arranged to move vertically. The lifting blocks 3 are connected with lifting bars 31 along the length direction of the clamping bar 23. In this example, one lifting block 3 is connected with two lifting bars 31 arranged at intervals; the lifting bars 31 are respectively arranged at both ends of the space between the clamping platform 21 and the pressing platform 22.

[0027] More specifically, Figure 4As shown, the mechanical structure acted upon by the device includes a connecting rod body 41, a steering bearing 42, and a rotating handle 43, wherein the top end of the connecting rod body 41 is vertically connected to the center of the rotating handle 43, and the diameter of the middle section of the connecting rod body 41 is smaller than the diameter of its top end, the steering bearing 42 is sleeved on the middle section of the connecting rod body 41, and the device is used to press the steering bearing 42 onto the top end of the connecting rod body 41.

[0028] During operation, the clamping platform 21 is moved and the spacing of the clamping strips 23 is enlarged, and the lifting block 3 is lifted so that the upper surface of the lifting strip 31 is flush with the upper surface of the clamping platform 21; the connecting rod body 41 is placed between the clamping strips 23 so that the steering bearing 42 just contacts with the side of the clamping platform 21 facing the pressing surface 24, and the rotating handle 43 is placed on the lifting strip 31. At this time, the spacing of the clamping strips 23 is reduced so that the clamping strips 23 clamp the connecting rod body 41, and the end of the clamping strip 23 facing the pressing surface 24 contacts with the steering bearing 42, and the clamping platform 21 is moved toward the pressing platform 22, so that the connecting rod body 41 moves between the clamping strips 23 along its own length direction, so that the clamping platform 21 and the clamping strip 23 push the steering bearing 42 until the steering bearing 42 is pressed to the top of the connecting rod body 41; at this time, the spacing of the clamping strips 23 is enlarged and the lifting block 3 is lifted, so that the lifting strip 31 lifts the rotating handle 43 upward to complete the pressing.

[0029] Preferably, Figure 1 and Figure 2 As shown, a driving track 11 parallel to the clamping bar 23 is provided on the upper surface of the loading platform 1. The clamping platform 21 slidably cooperates with the driving track 11. A first electric screw 12 is provided in the driving track 11. The first electric screw 12 cooperates with the clamping platform 21 to drive the clamping platform 21 to move.

[0030] Preferably, Figure 2 and Figure 4 As shown, the opposite side of the top of the clamping strip 23 is an arc surface, which is used to more conveniently place the connecting rod body 41; two fixing strips 25 are provided on the upper surface of the clamping platform 21 along the length direction of the clamping strip 23, and the fixing strips 25 are respectively arranged on the two opposite sides of the clamping strip 23, and a spring 26 is vertically connected between the clamping strip 23 and the corresponding fixing strip 25. In this example, three springs 26 are connected between one clamping strip 23 and its corresponding fixing strip 25; a limiting groove 27 perpendicular to the clamping strip 23 is opened on the upper surface of the clamping platform 21, and in this example, two limiting grooves 27 are provided; a limiting strip 28 matching the number of the limiting grooves 27 is provided at the bottom of the clamping strip 23, and the limiting strip 28 is slidably fitted in the limiting groove 27 to limit the moving direction of the clamping strip 23. When working, the connecting rod body 41 can be directly placed between the clamping strips 23 to complete the clamping, and there is no need to add an additional linear mechanism to the clamping strip 23.

[0031] Preferably, Figure 1 and Figure 3 As shown, two L-shaped plates 32 are provided on the loading platform 1, and the L-shaped plates 32 include a horizontal part and a vertical part. The vertical part is vertically connected to the loading platform 1, and a lifting rod 33 and a second electric screw 34 are vertically provided between the horizontal part and the loading platform 1. The lifting block 3 is slidably sleeved on the lifting rod 33 and cooperated with the second electric screw 34. The second electric screw 34 is used to drive the lifting block 3 to move vertically.

[0032] Preferably, Figure 2 and Figure 4 As shown, a rotating mechanism 29 and a rotating frame 210 are provided at the upper end of the pressing platform 22. The rotating mechanism 29 can adopt a rotating drive mechanical device such as a rotating motor and a rotating cylinder. The rotating mechanism 29 is horizontally arranged and perpendicular to the clamping bar 23. The rotating frame 210 is rotatably arranged around one end thereof, and the one end is coaxially connected to the driving shaft of the rotating mechanism 29. The rotating mechanism 29 is used to drive the rotating frame 210 to rotate around one end thereof and make the other end contact with the top of the clamping bar 23 to prevent the connecting rod body 41 from running out from the top of the clamping bar 23 during pressing.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
