Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball processing technology, specifically to a steel ball processing device for bearings of high-speed letterpress printing machines. Background Technology

[0002] High-speed letterpress printing machines require high-precision rotation and positioning of components such as printing cylinders and printing plate rollers. As an important component of rolling bearings, bearing steel balls can reduce friction and enable these cylinders and rollers to rotate smoothly and accurately. Therefore, it is necessary to ensure their stability during the processing of bearing steel balls. For example, patent document CN213416947U discloses a heat treatment quenching device for processing wind turbine bearing steel balls. This device can not only remove all the steel balls after quenching, but also move the steel balls up and down, resulting in better quenching effect. At the same time, it reduces the need for manual retrieval of steel balls and greatly speeds up the removal rate of steel balls.

[0003] However, during the quenching process of the bearing steel balls, operators still need to intermittently retrieve the steel balls from the quenching pool, which makes the quenching work of the steel balls unable to be carried out continuously and increases labor costs. Summary of the Invention

[0004] In view of the problems existing in the current steel ball processing device for bearings of high-speed letterpress printing machines, this utility model is proposed.

Multiple placement boxes evenly distributed axially are fixedly embedded on the side of the rotating plate. A material cylinder is provided on the top of the mounting plate. The material cylinder is located at the upper end of the rotating plate and is fixedly mounted with a fixing frame between it and the mounting plate. A push hole is opened on the front side of the placement box. A support frame is fixedly installed on the top of the side wall of the quenching tank. An electric push rod is fixedly inserted through the upper end of the support frame. The output shaft of the electric push rod is fitted with the push hole.

[0008] Preferably, a drive motor is fixedly installed on the upper back side of the quenching tank, a sector gear is fixedly installed at the end of the output shaft of the drive motor, and a transmission gear is fixedly installed inside the support rod, with the sector gear and the transmission gear being configured to cooperate.

[0009] Preferably, a baffle is slidably provided on the upper side of the placement box, and a limiting spring is sleeved on the baffle. The two ends of the limiting spring are fixedly connected to the placement box and the baffle, respectively.

[0010] Furthermore, a downward slope is provided on the upper side of one end of the baffle located inside the placement box.

[0011] Preferably, a feeding track is fixedly provided on the back side of the quenching tank.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a steel ball processing device for bearings of high-speed letterpress printing machines.

[0022] This utility model provides, for example Figure 1-4 The high-speed letterpress printing machine bearing steel ball processing device shown includes a quenching tank 1 and a mounting plate 2 fixedly installed on the top of the quenching tank 1. A support rod 3 is rotatably installed inside the mounting plate 2. A rotating plate 4 is fixedly sleeved on the wall of the support rod 3. Multiple placement boxes 5 evenly distributed axially are fixedly embedded on the side of the rotating plate 4. A material cylinder 6 is provided on the top of the mounting plate 2. The material cylinder 6 is located at the upper end of the rotating plate 4 and a fixing frame 7 is fixed between it and the mounting plate 2. A drive motor 13 is fixedly installed on the upper back side of the quenching tank 1. A sector gear 14 is fixedly installed at the end of the output shaft of the drive motor 13. A transmission gear 15 is fixedly installed inside the support rod 3. The sector gear 14 and the transmission gear 15 are configured to cooperate. A push hole is opened on the front side of the placement box 5. A support frame 8 is fixedly installed on the top of the side wall of the quenching tank 1. An electric push rod 9 is fixedly installed on the upper end of the support frame 8. The output shaft of the electric push rod 9 is connected to the push hole. A feeding track 18 is fixedly installed on the back side of the quenching tank 1.

[0023] To ensure the stability of the steel balls within the placement box 5 and thus improve the quenching effect, such as... Figure 3-4 As shown, the back side of the placement box 5 has a discharge hole and is covered by a cover plate 10. The upper end of the back side of the placement box 5 has a groove, and a crossbar 11 is fixedly installed in the groove. The upper end of the cover plate 10 is rotatably engaged with the crossbar 11. A torsion spring 12 is sleeved on the wall of the crossbar 11. The two ends of the torsion spring 12 are fixedly connected to the crossbar 11 and the cover plate 10, respectively. A baffle 16 is slidably installed on the upper side of the side of the placement box 5. A sliding inclined surface is opened on the upper side of the baffle 16 located inside the placement box 5. A limiting spring 17 is sleeved on the baffle 16. The two ends of the limiting spring 17 are fixedly connected to the placement box 5 and the baffle 16, respectively.

[0024] Working principle: First, multiple steel balls are placed in the material cylinder 6. As the number of steel balls increases, the bottom steel balls begin to push the baffle 16. Under the action of the downward inclined plane, the baffle 16 moves laterally and opens the top of the placement box 5, allowing the bottom steel balls to enter the placement box 5. Under the push of the limiting spring 17, the top of the placement box 5 is blocked, thus restricting the top of the steel balls. At the same time, the back cover plate 10 closes the discharge hole under the action of the torsion spring 12 to stably support the steel balls. Then the drive motor 13 is started, so that the drive motor 13 drives the support rod 3 and the rotating plate 4 to rotate through the meshing of the sector gear 14 and the transmission gear 15, so that the placement box 5 rotates into the quenching pool 1. Because the sector gear 14 and the transmission gear 15 mesh intermittently, multiple placement boxes 5 can stay in the quenching pool 1 and be effectively quenched. After quenching, the placement box 5 rotates to the back of the electric push rod 9. At this time, the electric push rod 9 is activated and extends into the placement box 5 through the push hole to push the steel ball forward. The steel ball squeezes the baffle 16, causing the limit spring 17 to compress. At the same time, the cover plate 10 is squeezed by the steel ball and rotates around the cross bar 11 to open the discharge hole. The steel ball moves away from the placement box 5 and falls onto the unloading track 18, thus completing the quenching of the steel ball. The overall operation reduces manual intervention and improves processing efficiency.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
