Description

Technical Field

[0001] This utility model relates to the field of bearing ball technology, and in particular to a ball feeding device for bearing production. Background Technology

[0002] During bearing installation, the balls need to be transported to a ball bearing installation machine, which presses multiple balls into the bushing at the same time.

[0003] To ensure that the ball bearing installation machine can arrange the balls at a uniform speed, the ball bearing feeder transports the balls at a slow speed and uses a single-ball transport method. Since there are many balls in the feeder, the feed inlet can only accommodate one ball at a time. Multiple balls that are pressed together block the feed inlet. Therefore, the operator needs to manually and continuously move the balls so that the balls in the feed inlet can move and not continuously block the feed inlet. However, this operation is labor-intensive and does not improve the ball feeding efficiency. Utility Model Content

[0004] The purpose of this application is to provide a ball bearing feeding device for bearing production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A ball bearing feeding device for bearing production includes a feeding bin and a feeding assembly installed at the bottom of the feeding bin. A base plate is fixedly installed on one outer wall of the feeding bin, and the base plate is fixedly installed on the ball bearing feeding station. Multiple slots are opened through the bottom inner wall of the feeding bin. The feeding assembly includes multiple feeding pipes and multiple sleeves. The number of multiple feeding pipes and sleeves corresponds to the number of slots at the bottom of the feeding bin. Multiple feeding pipes are installed inside the slots at the bottom of the feeding bin. The bottom outer wall of the feeding pipe is fixedly installed on the ball bearing feeding station, and multiple sleeves are respectively sleeved on the outer wall of the feeding pipe.

[0007] Preferably, the top end of the feed tube is a slope, the top end face of the sleeve is a concave slope, the inner wall of the sleeve is in contact with the outer wall of the feed tube, a cylinder is fixedly installed on the outer wall of the base plate, and the sleeve is driven by the cylinder. The output end of the cylinder faces downwards from the base plate, and a fixing plate is fixedly installed on the output end of the cylinder. The outer walls of multiple sleeves are fixedly connected to the fixing plate.

[0008] Preferably, a guide block is provided on one side of each of the multiple slots at the bottom of the feeding hopper, and the top outer wall of each guide block is inclined, with a groove formed on the inclined top surface of the guide block. A feeding port is formed on one side of each of the multiple feeding pipes, and the lower end of the inclined top surface of each guide block is installed facing the feeding port. The feeding port is located close to the bottom inner wall of the feeding hopper.

[0009] The beneficial effects of this utility model are: by setting up a feeding component and multiple feeding pipes, multiple feeding pipes can transport the balls simultaneously, improving work efficiency. A small number of balls enter the feeding pipe from the feeding port, which allows the small number of balls at the bottom of the feeding bin to be quickly cleaned up, improving the feeding efficiency of the balls.

[0017] like Figure 1-5 The ball bearing production ball unloading device shown includes a unloading bin 1 and an unloading assembly installed at the bottom of the unloading bin 1. A base plate 2 is fixedly installed on one outer wall of the unloading bin 1. The base plate 2 is fixedly installed on the ball unloading station. Multiple slots are opened through the bottom inner wall of the unloading bin 1. The unloading assembly includes multiple unloading pipes 6 and multiple sleeves 4. The number of multiple unloading pipes 6 and sleeves 4 corresponds to the bottom slots of the unloading bin 1. Multiple unloading pipes 6 are installed inside the bottom slots of the unloading bin 1. The bottom outer wall of the unloading pipe 6 is fixedly installed on the ball unloading station. Multiple sleeves 4 are respectively sleeved on the outer wall of the unloading pipe 6.

[0018] The top of the feed tube 6 is beveled, and the top end face of the sleeve 4 is concave beveled. The inner wall of the sleeve 4 fits against the outer wall of the feed tube 6. A cylinder 3 is fixedly installed on the outer wall of the base plate 2, and the sleeve 4 is driven by the cylinder 3. The output end of the cylinder 3 faces downwards from the base plate 2, and a fixing plate 5 is fixedly installed on the output end of the cylinder 3. The outer walls of multiple sleeves 4 are fixedly connected to the fixing plate 5.

[0019] Guide blocks 7 are provided on one side of multiple slots at the bottom of the feeding bin 1. The top outer wall of the multiple guide blocks 7 is inclined, and a sliding groove 8 is opened on the top inclined surface of the guide blocks 7. A feeding port 9 is opened on one side of the outer wall of multiple feeding pipes 6. The lower end of the top inclined surface of the multiple guide blocks 7 is installed facing the feeding port 9. The feeding port 9 is located close to the bottom inner wall of the feeding bin 1.

[0020] Example: The balls are poured into the feeding hopper 1. In the initial state, the top of the sleeve 4 is close to the bottom inner wall of the feeding hopper 1, while blocking the feeding port 9 on the outer wall of the feeding pipe 6. Some balls enter the feeding pipe 6 directly from the top opening of the feeding pipe 6. The bottom end of the feeding pipe 6 is connected to the external ball bearing installation machine pipe. The balls move from the pipe to the ball bearing installation machine. Due to the large number of ball bearings, multiple ball bearings may block the top opening of the feed tube 6. The cylinder 3 on the base plate 2 is activated, driving the fixing plate 5. The fixing plate 5 then drives multiple sleeves 4 to slide upwards along the outer wall of the feed tube 6. The concave slope at the top of each sleeve 4 can catch multiple ball bearings. As the sleeves 4 move upwards until they exceed the top of the feed tube 6, they push away the ball bearings blocking the opening. Then, as the cylinder 3 drives the sleeves 4 downwards, some of the ball bearings at the top of the sleeves 4 will fall through the slope at the top of the feed tube 6. The cylinder 3 drives the sleeves 4 to move up and down repeatedly, continuously feeding ball bearings into the feed tube 6. The multiple feed tubes 6 and sleeves 4 allow multiple feed tubes 6 to transport ball bearings simultaneously, improving work efficiency.

[0021] After most of the balls are transported out of the discharge bin 1, a small number of balls remaining at the bottom of the discharge bin 1 slide from the groove 8 on the top slope of the guide block 7 to the position where the discharge port 9 is opened in the discharge pipe 6. The cylinder 3 drives the sleeve 4 to descend, so that the top edge of the sleeve 4 is flush with the bottom inner wall of the discharge bin 1, the discharge port 9 is opened, and a small number of balls slide from the groove 8 into the discharge port 9, so that a small number of balls enter the discharge pipe 6. This allows the small number of balls at the bottom of the discharge bin 1 to be quickly cleared, improving the discharge efficiency of the balls.

[0022] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
