Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a four-station accessory switching device. Background Art

[0002] The bearing cage, also known as the bearing cage or bearing retainer, is an important component used to support and position the rolling elements of the bearing (such as balls, rollers, etc.). It is usually made of metal or plastic and has a specific shape and structure to ensure that the rolling elements of the bearing maintain the correct spacing and relative position during movement. The bearing cage requires blanking equipment when installed.

[0003] For example, the patent authorization announcement number CN216511505U discloses a feeder for bearing retainer production. However, since it has only a single station, when the bearing retainer on the storage rod is used up, it is time-consuming to replace it. In addition, the bearing retainer on the storage rod does not have the function of limiting the storage rod during feeding, which may cause the storage rod to shake and affect the feeding effect of the bearing retainer. Therefore, it is urgent to design a four-station accessory switching device. Utility Model Content

Two slides are symmetrically slidably arranged inside the limit box, and the opposite ends of the horizontal sides of the two C-shaped plates respectively pass through the two second rectangular grooves and are respectively fixedly installed on the sides away from the two slides, so that when the two slides move, the two clamping blocks can be driven to move through the two C-shaped plates, thereby realizing the limitation of the storage rod in the horizontal direction.

[0009] As a further technical solution of the utility model, a bidirectional lead screw is installed horizontally and rotatably inside the limit box, the surface of the bidirectional lead screw is connected to the inside of the two slides through threads, a drive motor is installed outside the limit box, and the output shaft of the drive motor is installed at the center of the end face of the bidirectional lead screw, which is used to make the two slides move toward or oppositely.

[0011] The beneficial effects of the utility model are:

[0012] The utility model can limit the storage rod that is discharging materials by means of a fixed limit box and a movably arranged clamping block and a pressing block, and can limit the position in two ways simultaneously, thereby ensuring that the storage rod and the bearing retainer sleeved on the storage rod will not be skewed, improving the stability of the bearing retainer during discharging materials, and accelerating the process of assembling the bearing retainer.

[0023] The limit assembly includes: a limit box 4, two clamping blocks 11 are symmetrically arranged below the limit box 4, a first rectangular groove 18 is opened at the bottom of the limit box 4, a pressure block 14 is vertically and slidably arranged inside the limit box 4, and the pressure block 14 is adapted to the first rectangular groove 18. Through the setting of the limit assembly, it is used to limit the storage rod 8 in the working state from two directions, while the storage rod 8 in the non-working state is not limited, so as to facilitate the loading of the storage rod 8 in the non-working state.

[0024] Please see attached Figure 1 -Attached Figure 4 In a preferred embodiment, a U-shaped frame 2 is horizontally fixedly installed on the top of the base 1, an L-shaped frame 3 is fixedly installed on the top of the horizontal side of the U-shaped frame 2, a limit box 4 is fixedly installed on the bottom of the horizontal side of the L-shaped frame 3, and the opposite sides of the limit box 4 are provided with second rectangular grooves 19, and the sides away from the two clamping blocks 11 are fixedly installed with C-shaped plates 10, and two slide plates 9 are symmetrically slidably arranged inside the limit box 4, and the opposite ends of the horizontal sides of the two C-shaped plates 10 respectively pass through the two second rectangular grooves 19 and are respectively fixedly installed on the sides away from the two slide plates 9, so that when the two slide plates 9 move, they can drive the two clamping blocks 11 to move through the two C-shaped plates 10, thereby limiting the storage rod 8 from the horizontal direction.

[0025] Please see attached Figure 3 -Attached Figure 4 In a preferred embodiment, a bidirectional lead screw 12 is installed horizontally and rotatably inside the limit box 4, and the surface of the bidirectional lead screw 12 is connected to the inside of the two slides 9 by threads. A drive motor 13 is installed outside the limit box 4, and the output shaft of the drive motor 13 is installed at the center of the end face of the bidirectional lead screw 12, which is used to move the two slides 9 toward or away from each other.

[0026] Please see attached Figure 1 -Attached Figure 4In a preferred embodiment, connecting rods 15 are rotatably installed on the opposite sides of the pressing block 14, and the other two ends of the two connecting rods 15 are rotatably installed on the opposite sides of the two slides 9, respectively.

The rotation of the bidirectional screw 12 will drive the two slides 9 to move synchronously. The movement of the two slides 9 will drive the two C-shaped plates 10 and the two connecting rods 15 to move. The movement of the two connecting rods 15 will drive the pressing block 14 to move. The pressing block 14 moves downward and passes through the first rectangular groove 18 and extends out of the limit box 4 and presses against the top of the storage rod 8 in the working state, so that the working storage rod 8 can be limited from above. The movement of the other two C-shaped plates 10 will drive When the two clamping blocks 11 move, the two clamping blocks 11 will clamp the working storage rod 8 in the horizontal direction, further ensuring the stability of the storage rod 8 when working, thereby improving the stability of the vertical unloading of the bearing retainer, and can be loaded on other storage rods 8 that are not in the working state. When the bearing retainer on one of the storage rods 8 is unloaded, the movable slider drives the four unloading stations 5 to be used alternately (the movement of the slider is completed by the screw rod and the stepper motor, the screw rod is installed inside the slider through a thread, and the stepper motor and the screw rod are connected), so that the bearing retainer can be unloaded continuously, thereby improving the unloading efficiency of the bearing retainer.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
