Description

Technical Field

[0001] The utility model relates to the technical field of cross shaft bearings, in particular to automatic assembly equipment for cross shaft bearings. Background Art

[0002] The cross-axis bearing is a bearing formed by two mutually perpendicular axes connected by a special structure. It can realize the transmission of power or torque at different angles. When assembling the shaft sleeve of the cross-axis bearing during its manufacturing process, it is often placed on four shaft frames on a turntable through a mechanical claw. When the turntable brings it to the assembly position, it pushes the two shaft frames to raise the cross-axis and detach it from the two shaft frames. Then the assembly mechanism assembles the shaft sleeves on the two ends of the cross-axis that are detached from the shaft frames. After the assembly is completed, the cross-axis is reset and the shaft sleeves are assembled on the other two ends after the angle is changed.

[0003] However, most of the existing automatic bushing assembly equipment lacks a fixed clamping mechanism. In the process of pushing the two shaft frames to raise the cross shaft and detach it from the two shaft frames, the cross shaft is easily displaced due to being detached from the support of the two shaft frames, which leads to assembly errors and affects product quality.

[0004] Therefore, a cross shaft bearing automatic assembly device is proposed. Utility Model Content

[0025] like Figures 1 to 5As shown, a specific embodiment of the utility model provides an automatic assembly device for a cross-axis bearing, including an assembly table 1, a turntable 2 arranged on the assembly table 1, and a support plate 3 fixedly installed on the turntable 2, a cross-axis 4 is placed on the top of the support plate 3, and a bearing plate 5 is fixedly installed on the assembly table 1; a fixing component for clamping and limiting the cross-axis 4 is provided on the bearing plate 5, and the cross-axis 4 can be clamped and fixed by setting the fixing component, so that its position will not change when assembling the shaft sleeve, thereby more accurately assembling the shaft sleeve, the fixing component includes an elastic member and a clamping plate 6 arranged on the top of the turntable 2, and a pressure plate 7 is fixedly connected to the bottom end of the elastic member; it also includes a lifting component arranged between the assembly table 1 and the support plate 3 for lifting the cross-axis 4, and the lifting component can be set to make the cross-axis 4 rise upward to cooperate with the assembly of the shaft sleeve, and the lifting component includes a lifting table 8 fixedly installed on the assembly table 1, and a rotating rod 9 for lifting the cross-axis 4 in cooperation with the lifting table 8 is provided at the bottom of the support plate 3.

[0026] like Figures 2 to 5 As shown, specifically, a short axis frame 10 and a long axis frame 11 are provided on the support plate 3, the short axis frame 10 is fixedly connected to the support plate 3, and the long axis frame 11 is slidably connected to the support plate 3, an arc surface 19 is provided on the clamping plate 6, and a slope surface is provided on the lifting platform 8, a connecting rod 20 is fixedly installed on the bottom end of the long axis frame 11, and the rotating rod 9 is rotatably connected with the connecting rod 20, after the cross shaft 4 is placed on the short axis frame 10 and the long axis frame 11, the turntable 2 drives the support plate 3 and the connecting rod 20 at the bottom to move, thereby driving the rotating rod 9 on the connecting rod 20 to move, and after the rotating rod 9 approaches the lifting platform 8 and contacts it, the continuous rotation of the turntable 2 and the cooperation of the rotating rod 9 and the slope surface make the rotating rod 9 drive the connecting rod 20 to rise upward, thereby making the long axis frame 11 move upward and rise, and then drive the cross shaft 4 to rise upward, until the rotating rod 9 moves to the highest position of the lifting platform 8 driven by the turntable 2 and the turntable 2 stops rotating, which is the position of assembling the sleeve.

[0027] like Figures 2 to 5As shown, specifically, a bracket 13 is fixedly connected to the carrier plate 5, a connecting frame 14 is fixedly connected to the bracket 13, a first spring 15 is fixedly connected to the connecting frame 14, and the first spring 15 is fixedly connected to the clamping plate 6, a first telescopic rod 16 is fixedly connected between the clamping plate 6 and the connecting frame 14, the elastic member includes a second spring 17 and a second telescopic rod 18, the second spring 17 and the second telescopic rod 18 are fixedly connected between the pressing plate 7 and the bracket 13, at the same time, when the long axis frame 11 drives the cross shaft 4 to rise or in the process, the middle part of the cross shaft 4 gradually approaches the pressing plate 7 and applies pressure to it, so that the second spring 17 and the second telescopic rod 18 are forced to shrink, and the second spring 17 generates a reaction force to push the pressing plate 7 to press the middle position of the cross shaft 4, and when the cross shaft 4 rises, its two ends are close to the pressing plate 7. Near the clamping plate 6, due to the action of the arc surface 19, the cross shaft 4 gradually enters between the clamping plates 6, and the clamping plate 6 causes the first spring 15 and the first telescopic rod 16 to be contracted under force, and the first spring 15 generates a reaction force to push the clamping plate 6 to clamp and fix the two ends of the cross shaft 4. At this time, under the joint pressing and clamping action of the pressure plate 7 and the clamping plate 6, the raised cross shaft 4 can be clamped and fixed, so as to facilitate the subsequent assembly of the shaft sleeves at both ends of the cross shaft 4 separated from the short axis frame 10. After the shaft sleeves are assembled, the turntable 2 drives the support plate 3 to move again, so that the rotating rod 9 at the bottom end gradually separates from the lifting platform 8. During the separation process, the cross shaft 4 and the long axis frame 11 are pushed downward under the reaction force of the second spring 17, so that the long axis frame 11 drives the cross shaft 4 to reset.
