This new spring press-fit device can smoothly press the spring down into the needle roller bearing, avoiding the dangers of warping and splashing, and can also ensure the concentricity of the spring and the spring groove during the pressing and fitting process, and will not cause the phenomenon of biased pressure, and can effectively avoid the intrusion of pollutants and ensure product quality.

[0004] However, the above patent has certain defects when in use. The device also requires manual removal of the press-fitted bearing from the guide hole of the retaining ring. Since the bearing is not easy to remove from the guide hole, the efficiency is low, which affects the production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 3 As shown, a press-fitting device for producing a retaining ring bearing comprises a base 2, a workbench 1 is provided at the upper end of the base 2, a work panel 11 is provided on the upper surface of the workbench 1, guide holes 12 are provided around the working panel 11, a guide column 3 is provided in the guide hole 12, a crossbeam 4 is provided on the top of the guide column 3, and the crossbeam 4 is fixedly connected to the guide column 3;

[0024] An electric hydraulic device 5 is provided at the bottom of the cross beam 4, a pressure plate 6 is provided at the output end of the electric hydraulic device 5, and a pressure head 7 is provided below the pressure plate 6;

[0025] The working panel 11 is provided with a positioning hole 14, and the working table 1 is provided with an ejection device, which is used for ejecting the bearing.

[0026] The ejection device includes an electric telescopic cylinder 94, the output end of the electric telescopic cylinder 94 is provided with a connecting plate 93, the upper end of the connecting plate 93 is provided with a connecting rod 92, the upper end of the connecting rod 92 is provided with a ejection column 9, and the ejection column 9 is arranged in a positioning hole 14. The aperture of the positioning hole 14 is larger than the bearing, and the bearing can fall into it, and the ejection column 9 is flush with the working panel 11 in the initial position.

[0027] A pressure rod 8 is provided on the side of the lower end of the pressure plate 6, and the length of the pressure rod 8 is greater than that of the pressure head 7. A starting switch 13 is provided on the same side of the upper surface of the working panel 11 and the pressure rod 8. When the starting switch 13 is pressed, the electric telescopic cylinder 94 is retracted, and the bearing falls into the guide hole 12, which makes it convenient for the pressure head 7 to press the retaining ring and the bearing. When the starting switch 13 is restored to its original state, the electric telescopic cylinder is pushed out to restore the initial position and push the bearing out of the guide hole 12.

[0028] There are multiple positioning holes 14, the number of the pressure heads 7 is the same as the number of the positioning holes 14, and the pressure heads 7 are located directly above the positioning holes 14;

[0029] The number of the push posts 9 is consistent with the number of the positioning holes 14. The cooperation between the multiple push posts 9, the positioning holes 14 and the pressing head 7 can press multiple bearings at the same time, which greatly improves the work efficiency.

[0030] A guide block 91 is disposed on the side wall of the top column 9 , and slide grooves for the guide block 91 to move are disposed on both sides of the positioning hole 14 . The guide block 91 moves up and down along the slide grooves to prevent the top column 9 from deviating and reduce wear.

[0031] The use principle of the utility model is as follows: when in use, the bearing is first placed in the positioning hole 14. Since the start switch 13 is not started, the top column 9 is located at the top of the positioning hole 14, the electric hydraulic device 5 is started, and the output end of the electric hydraulic device 5 moves downward, driving the pressure plate 6 to move downward, thereby driving the pressure head 7 to move downward. Since the length of the pressure rod 8 is longer than the length of the pressure head 7, the pressure rod 8 first contacts the start switch 13. After the start switch 13 is started, the electric telescopic cylinder 94 begins to contract, moving the top column 9 downward. After finally stopping, the pressure head 7 presses the retaining spring and the bearing together;

[0032] After the bearing is installed, the electric hydraulic device 5 is retracted to the initial position, and the pressure rod 8 is removed from the start switch 13. At this time, the electric telescopic cylinder 94 is restored to the state, and the top column 9 is pushed upward, so that the bearing is pushed out of the guide hole 12, which is convenient for removal and greatly improves work efficiency.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
