DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See also Figure 1-Figure 2The utility model provides an assembly device for a bearing end cover, including a holding platform 1, on which a heating mechanism 2 is arranged; the heating mechanism 2 includes a U-shaped plate 21, which is fixedly connected to the lower surface of the holding platform 1 in a linear array, and a heating machine 22 is fixedly connected to the inner surface of the U-shaped plate 21, and a moving groove 23 is provided on the upper surface of the heating machine 22, and an arc plate 24 is slidably connected to the inner surface of the moving groove 23. In order to ensure that the arc plate 24 can slide stably, the arc plate 24 is limited by the moving groove 23, so that the arc plate 24 can only slide in the moving groove 23, thereby making the arc plate 24 more stable, and a circular groove 25 is provided on the upper surface of the holding platform 1, and the inner surface of the circular groove 25 is slidably connected to the arc plate 24, and the inner surface of the circular groove 25 is rotatably connected to a threaded rod 3, and the threaded rod 3 The arc plate 24 is penetrated and is threadedly connected with the arc plate 24. The right surface of the holding platform 1 is fixedly connected with a motor 4. When the motor 4 is started and the output shaft drives the threaded rod 3 to rotate, the threaded rod 3 will drive the arc plate 24 to move in the circular groove 25, thereby realizing the function of controlling the arc plate 24. The threaded rod 3 is fixedly connected to the output shaft of the motor 4. There are multiple groups of arc plates 24 and threaded rods 3. The multiple groups of arc plates 24 and threaded rods 3 are grouped in pairs. The threads of a group of threaded rods 3 are opposite. The threads of the threaded rods 3 of each group are set to be opposite. When the output shaft of the motor 4 rotates, the arc plates 24 will be driven to separate to both sides or aggregate to the middle. The spacing between the two arc plates 24 can be adjusted according to the inner diameter of the bearing, so that the bearing can be inserted into the arc plate 24, which is convenient for heating the bearing and facilitating the mechanical claw to grasp the bearing.

[0025] In this embodiment, by setting the U-shaped plate 21, the heating machine 22, the threaded rod 3 and the motor 4, the arc plate 24 can be adjusted according to the specifications of the bearing, so that the bearing can be placed on the arc plate 24 for easy removal. At the same time, when the bearing is installed, the bearing is heated to make the installation of the bearing more convenient. Example

[0026] See also Figure 2-Figure 4On the basis of the first embodiment, the utility model provides a technical solution: preferably, the outer arc surface of the arc plate 24 is provided with a bearing fixing mechanism 5, and the bearing fixing mechanism 5 includes a slide groove 51, and the outer arc surface of the arc plate 24 is provided with a slide groove 51, and the inner surface of the slide groove 51 is fixedly connected with a slide rod 52, and the outer arc surface of the slide rod 52 is slidably connected with a slider 53, and the slider 53 is limited by the opened slide groove 51 and the slide rod 52, so that the slider 53 can only slide on the slide rod 52, and the outer arc surface of the slider 53 is provided with a limiting hole 54, and the inner surface of the limiting hole 54 is slidably connected with a limiting rod 55, and the limiting rod 55 is fixedly connected to one end of the first spring 6, and the slider 53 is fixedly connected to the other end of the first spring 6, and the cross-sectional shape of the limiting rod 55 is conical. By setting the limiting hole 54 to be conical, after the bearing is inserted into the arc plate 24, the conical surface of the limiting rod 55 will limit the bearing, so that the bearing can be in a relaxed state. The outer arc surface of the slide bar 52 is provided with a slot 7 in a linear array, and the inner surface of the slot 7 is slidably connected with a slot rod 8, which passes through the slider 53 and is slidably connected to the slider 53. The cross-sectional shape of the slot rod 8 is trapezoidal. By setting the slot rod 8 to be trapezoidal, when the bearing is placed on the limit rod 55, the gravity of the bearing cannot make the slot rod 8 converge toward the center direction, so the slider 53 will not move downward. When the artificial downward force and the gravity of the bearing are pressed downward at the same time, the inclined surface of the trapezoidal end of the slot rod 8 will be squeezed by the inner surface of the slot 7, converge toward the center direction of the circular groove 25, and leave the slot 7. After the slot rod 8 no longer limits the slot 7, the slider 53 can slide on the slide bar 52, and the slider 53 is fixedly connected to one end of the second spring 9, and the slot rod 8 is fixedly connected to the other end of the second spring 9. The fixed second spring 9 makes the slot rod 8 more stable and will not be affected by the vibration force and leave the slot 7.

[0027] In this embodiment, by setting the limit rod 55, the slider 53, the first spring 6, the slot 7 and the clamping rod 8, and by the cooperation of the slot 7 and the clamping rod 8, the position of the slider 53 can be adjusted according to the specifications of the bearing. At the same time, through the tapered end of the limit rod 55, the bearing can be clamped in place for easy removal.

[0028] Working principle: when it is necessary to place the bearing, the motor 4 is started according to the inner diameter of the bearing, and the output shaft of the motor 4 drives the threaded rod 3 to rotate. After the two groups of threaded rods 3 rotate, they will drive the arc plate 24 to move in the aggregation and separation state, and the arc plate 24 moves in the moving groove 23 and the circular groove 25. When the outer arc surface of the arc plate 24 can fit the inner surface of the bearing, the bearing is inserted into the arc plate 24. After the bearing is inserted into the arc plate 24, the elastic force of the limit rod 55 and the first spring 6 is used to keep the bearing above the limit rod 55 at all times, which is convenient for the mechanical claw to grab. At the same time, the heating machine 22 is started to heat the bearing. When it is necessary to move the slider 53, the bearing is pressed downward manually. Through the gravity of the bearing and the pressing force, the inclined surface of the clamping rod 8 is squeezed by the clamping groove 7 and moves toward the center direction of the circular groove 25. After being out of the clamping groove 7, the slider 53 can slide on the slide rod 52.
