Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for bearing component production, and more specifically, to a bearing ring feeding device. Background Technology

[0002] The bearing inner ring is an important component used in bearings, such as... Figure 5 The image shows a semi-finished bearing inner ring used in wheel hub bearings. This semi-finished bearing inner ring needs to be loaded onto a machine tool for processing. Because the outer diameter of this semi-finished bearing inner ring differs from that of a conventional bearing inner ring (the outer diameter of a conventional bearing inner ring is the same size, while the outer diameter of this bearing inner ring has a small outer diameter segment and a large outer diameter segment), it needs to be installed in a fixed orientation during loading. Therefore, the requirements for automated conveying and loading are relatively high (it needs to be conveyed to the loading equipment in a fixed orientation). Currently, the company still uses a mode of manually picking up the material, determining the orientation, and then installing it on the machine tool for processing. With the increase in product sales, the low-efficiency production mode of manual picking is becoming increasingly difficult to meet production needs. The company is working on the technical breakthrough of automated conveying and loading for this type of bearing inner ring to meet production needs, and this case has arisen from this. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bearing ring feeding device. This invention realizes the feeding of bearing inner ring workpieces one by one through a conveyor belt. During the workpiece conveying process, it can complete a series of processes such as flipping and standing upright, and actively dropping and feeding. Furthermore, the orientation detection element can detect the orientation of the fed workpiece. Workpieces with incorrect orientation can be blocked and warned in time. This invention can realize automated and efficient conveying and feeding of bearing inner rings, and can meet the needs of enterprises to improve work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bearing ring feeding device is used in the conveying and feeding operation of an inner ring of a wheel hub bearing. It includes a conveyor belt and a feeding trough. The inner ring of the wheel hub bearing is conveyed by the conveyor belt. A feeding station is provided along the direction of movement of the conveyor belt. The feeding station is equipped with a dropper and a tilting seat. The dropper blocks the forward movement of the inner ring of the wheel hub bearing. The inner ring of the wheel hub bearing is blocked by the dropper and swept onto the tilting seat. The inner ring of the wheel hub bearing is tilted and upright within the tilting seat. The feeding trough is installed at an angle, and its highest point is connected to the tilting seat. The upright inner ring of the wheel hub bearing rolls down naturally along the feeding trough. On the side of the feeding trough, a feeding control element and a position detection element are sequentially installed along the rolling and falling direction of the inner ring of the wheel hub bearing.

[0006] Furthermore, the width of the conveyor belt is adapted to the conveying of a single inner ring of a wheel hub bearing, and the feeder includes a plate frame and a triangular plate. The triangular plate is fixedly installed on the plate frame and blocks the forward direction of the inner ring of the wheel hub bearing. The triangular plate is provided with an inclined surface, and the triangular plate faces the inner ring of the wheel hub bearing with the inclined surface.

[0007] Furthermore, the flipping seat includes a vertical groove, the width of which matches the thickness of the inner ring of the wheel hub bearing. The flipping seat includes a first side wall and a second side wall. The first side wall is connected to an inclined receiving plate, and the second side wall is connected to an inclined baffle plate. The height of the second side wall is higher than that of the first side wall. The inner ring of the wheel hub bearing, which is blocked and swept off by the dropper, falls down the slope of the receiving plate and is vertically flipped in the vertical groove.

[0008] Furthermore, the feeding control element includes a first frame, a plate base, and a contact switch. The first frame is fixedly connected to the side wall of the feeding trough, the plate base is fixedly installed on the first frame, and the rotating plate is rotatably connected to the plate base. A switch base is fixedly installed on the first frame, and the contact switch is fixedly installed on the switch base. The contact switch is installed vertically. The rotating plate includes a long side section and a short side section. The long side section hangs naturally downwards towards the lowest point of the feeding trough, and the short side section is located below the contact switch. The contact switch blocks the upward flipping movement path of the short side section.

[0009] Furthermore, the orientation detection element includes a second frame and a threaded rod. The second frame is fixedly connected to the side wall of the feeding trough, and the threaded rod is vertically installed on the second frame. The threaded rod passes through and is threadedly connected to the second frame. A chuck is connected to the bottom of the threaded rod, and an assist handle is connected to the top of the threaded rod.

[0010] Furthermore, the width of the feeding groove matches the thickness of the inner ring of the wheel hub bearing. The inner ring of the wheel hub bearing includes a small outer diameter section and a large outer diameter section. The threaded rod is installed on the inner ring of the wheel hub bearing in the correct orientation above the small outer diameter section when the material is being fed. The chuck of the threaded rod extends downward past the highest point of the large outer diameter section but does not touch the highest point of the small outer diameter section.

[0011] Furthermore, the orientation detection element also includes a sensor, which is embedded in the side wall of the feeding trough and installed facing the inside of the feeding trough.

[0012] Furthermore, an alarm light is installed on the outer wall of the feeding trough, and the alarm light is connected to the sensor circuit.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a conveyor belt to feed bearing inner ring workpieces one by one. After the bearing inner ring touches the unloading device, it automatically flips and stands upright, and then automatically rolls down the feeding chute. During the rolling process, the orientation is detected. Workpieces with incorrect orientation can be blocked and warned in time, making it easy for workers to remove incorrectly oriented workpieces in a timely manner. This utility model can realize automated and efficient conveying and feeding of bearing inner rings, which can meet the needs of enterprises to improve work efficiency.

[0015] 2. This utility model incorporates a feeding control element in the feeding trough. This feeding control element controls the opening and closing of the conveyor belt in conjunction with the feeding trough. When there are many workpieces in the feeding trough, the conveyor belt can be closed to prevent workpiece accumulation. When the amount of workpieces in the feeding trough decreases, the conveyor belt can be opened in time to feed materials to replenish the feeding trough. The design of the feeding control element makes the opening and closing of the conveyor belt automatic and orderly, which can meet production needs and reduce energy consumption on the conveyor belt.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 The bearing ring feeding device shown is applied in a type of... Figure 5 In the conveying and feeding operation of the inner ring 7 of the hub bearing shown, the inner ring 7 of this type of hub bearing is characterized by having a small outer diameter section 71 and a large outer diameter section 72. Its orientation needs to be fixed when installed on the machine tool chuck. Therefore, the orientation issue needs to be considered when designing an automatic conveyor. The bearing ring feeding device of this utility model includes a conveyor belt 1 and a feeding trough 4. The inner ring 7 of the hub bearing is conveyed by the conveyor belt 1. Figure 1(The arrow in the image indicates the workpiece conveying direction). The width of the conveyor belt 1 is adapted to convey a single inner ring 7 of the hub bearing. In other words, the inner rings 7 of the hub bearing are conveyed one by one. A feeding station 11 is provided along the movement direction of the conveyor belt 1. The feeding station 11 is equipped with a dropper 2 and a tilting seat 3. The dropper 2 blocks the forward movement of the inner ring 7 of the hub bearing. The inner ring 7 of the hub bearing is blocked by the dropper 2 and swept off onto the tilting seat 3. The tilting seat 3 is located on the side of the conveyor belt 1 and is designed to catch the swept-off hub bearing. The inner ring 7 of the bearing, specifically the inner ring 7 of the wheel hub bearing, is rotated and erected within the tilting seat 3. For ease of initial transport, the inner ring 7 of the wheel hub bearing on the conveyor belt 1 is initially in a flat position. However, the inner ring 7 of the wheel hub bearing to be loaded onto the machine tool needs to be erected. Therefore, the inner ring 7 of the wheel hub bearing needs to be rotated and erected via the tilting seat 3. The loading chute 4 is installed at an angle, with both its high and low ends open. The high point of the loading chute 4 connects to the tilting seat 3 to receive the inner ring 7 of the wheel hub bearing on the tilting seat 3. The erected inner ring 7 of the wheel hub bearing... The inner ring 7 of the wheel hub bearing rolls naturally down along the feeding trough 4 to achieve feeding. It is output from the lowest point of the feeding trough 4 and then fed onto the automatic loading machine matched with the machine tool (the automatic loading machine matched with the machine tool is used to grab and load a single inner ring 7 of the wheel hub bearing onto the machine tool fixture. The automatic loading machine is only functionally related to the solution of this application, so only its function is described and its structure is not described in detail). On the side of the feeding trough 4, along the rolling and falling direction of the inner ring 7 of the wheel hub bearing, a feeding control element 5 and an orientation detection element 6 are installed in sequence. The feeding control element 5 can detect the workpiece inventory in the feeding trough 4. It controls the conveyor belt 1 to open only when the workpiece inventory is low, which can reduce the operating energy consumption of the conveyor belt 1. Since the inner ring 7 of the wheel hub bearing needs to have a fixed orientation, the orientation detection element 6 is very necessary. It needs to detect the workpiece with incorrect orientation so that workers can easily remove it. This utility model can meet the automatic feeding of special bearing inner ring workpieces and help improve the production efficiency of the inner ring 7 of the wheel hub bearing.

[0024] like Figure 1 As shown, the feeder 2 includes a plate frame 21 and a triangular plate 22. The plate frame 21 is fixedly installed on the side of the conveyor belt 1, and the triangular plate 22 is fixedly installed on the plate frame 21. The triangular plate 22 blocks the forward direction of the inner ring 7 of the hub bearing. The triangular plate 22 has an inclined surface 221. The triangular plate 22 faces the inner ring 7 of the hub bearing with the inclined surface 221. During the forward movement of the inner ring 7 of the hub bearing, it contacts the inclined surface 221 and moves along the inclined surface, thereby achieving the effect of falling off the conveyor belt 1.

[0025] The flip seat 3 is located on the side of the inner ring 7 of the wheel hub bearing in the direction of its fall, such as... Figure 2As shown, the flipping seat 3 includes a vertical groove 31, the width of which matches the thickness of the inner ring 7 of the wheel hub bearing. The flipping seat 3 includes a first sidewall 311 and a second sidewall 312. The first sidewall 311 is connected to an inclined receiving plate 32. The falling inner ring 7 of the wheel hub bearing first falls onto the receiving plate 32. Due to the inclination of the receiving plate 32, the inner ring 7 of the wheel hub bearing slides down along the receiving plate 32 until it falls into the vertical groove 31. The inner ring 7 of the wheel hub bearing that falls into the vertical groove 31 naturally flips and stands upright. The side wall 312 is connected to an inclined baffle plate 33. The height of the second side wall 312 is higher than that of the first side wall 311. The above design is to enable the inner ring 7 of the wheel hub bearing to rotate smoothly and to prevent the inner ring 7 of the wheel hub bearing from popping out. The bottom of the vertical groove 31 should also be designed to be inclined. The lowest point of the groove bottom is connected to the feeding groove 4. In this way, the upright inner ring 7 of the wheel hub bearing can roll down naturally into the feeding groove 4. The width of the feeding groove 4 is consistent with that of the vertical groove 31 to ensure that the inner ring 7 of the wheel hub bearing falls smoothly.

[0026] like Figure 3 As shown, the feeding control element 5 includes a first frame 51, a plate base 52, and a contact switch 55. The first frame 51 is fixedly connected to the side wall of the feeding trough 4. The plate base 52 is fixedly installed on the first frame 51. The rotating plate 53 is rotatably connected to the plate base 52. A switch base 54 is fixedly installed on the first frame 51. The contact switch 55 is fixedly installed on the switch base 54 and is vertically installed. The rotating plate 53 includes a long side section 531 and a short side section 532. The long side section 531 faces... The loading trough 4 hangs naturally downwards from its lowest point. The short side segment 532 is located below the contact switch 55. The contact switch 55 blocks the upward flipping movement path of the short side segment 532. Since the long side segment 531 of the rotating plate 53 is significantly heavier than the short side segment 532, if there is no downward obstruction, the long side segment 531 of the rotating plate 53 will naturally hang downwards and flip. When there is a large amount of workpiece in the loading trough 4, there will definitely be workpiece below the long side segment 531. Therefore, the long side segment 531... The workpieces will be lifted up. As the machine tool is used, the amount of workpieces in the feeding trough 4 will decrease until there are no workpieces under the long side section 531. Then the long side section 531 will droop and flip down. At this time, the short side section 532 will flip up, which will create a collision triggering effect on the contact switch 55. The circuit of the contact switch 55 is connected to the motor of the conveyor belt 1. After the contact switch 55 is triggered, the conveyor belt 1 will start. After the conveyor belt 1 starts, it can continuously transport the inner ring of the hub bearing 7 into the feeding trough 4 for replenishment. After the inner ring of the hub bearing 7 is replenished, the rotating plate 53 will reset and lift up again. This can control the conveyor belt 1 to close. The position of the motor of the conveyor belt 1 can be set with electrical components that delay opening and closing to realize the control of the feeding replenishment amount of the conveyor belt 1. It is best to replenish about 10 workpieces each time the conveyor belt 1 is turned on. This can well adapt to the consumption of workpieces by the machine tool. After the above design, the conveyor belt 1 does not need to be turned on all the time, which can meet the production needs and reduce the energy consumption of the conveyor belt.

[0027] like Figure 4As shown, the orientation detection element 6 includes a second frame 61 and a threaded rod 62. The second frame 61 is fixedly connected to the side wall of the feeding trough 4. The threaded rod 62 is vertically installed on the second frame 61, passing through and threadedly connected to the second frame 61. A chuck 63 is connected to the bottom of the threaded rod 62, and an assist handle 64 is connected to the top of the threaded rod 62. The assist handle 64 has knurled patterns. By turning the assist handle 64, the threaded rod 62 and the chuck 63 can be raised and lowered. Figure 4 As shown, the width of the feeding groove 4 matches the thickness of the inner ring 7 of the wheel hub bearing. The threaded rod 62 is installed on the inner ring 7 of the wheel hub bearing in the correct orientation above the small outer diameter section 71 when the material is falling. The chuck 63 of the threaded rod 62 extends downward past the highest point of the large outer diameter section 72 but does not touch the highest point of the small outer diameter section 71. Figure 4 The correct orientation of the inner ring 7 of the wheel hub bearing in the feeding groove 4 is as follows: the smaller outer diameter section 71 is on the right, and the larger outer diameter section 72 is on the left. At this time, the clamp 63 is positioned above the smaller outer diameter section 71. The presence of the clamp 63 does not affect the position of the inner ring 7 of the wheel hub bearing through the orientation detection element 6. If the orientation of the inner ring 7 of the wheel hub bearing is reversed, the larger outer diameter section 72 is on the right. In this case, the clamp 63 will block the outer wall of the larger outer diameter section 72, causing the inner ring 7 of the wheel hub bearing to be unable to fall. This invention utilizes this point by designing a sensor 65 on the orientation detection element 6. The sensor 65 is embedded and installed on the side wall of the feeding groove 4. The sensor 65 is installed inside the feeding trough 4. It is an infrared sensor. If the inner ring 7 of the wheel hub bearing cannot fall, the sensor 65 will be continuously triggered. An alarm light 66 is installed on the outer wall of the feeding trough 4. The alarm light 66 is connected to the sensor 65. The continuously triggered sensor 65 will control the alarm light 66 to stay lit (red light) to alert the worker that there is an abnormal workpiece. The worker uses manual operation to remove the abnormal workpiece. Since the conveyor belt 1 has already been sorted when feeding, abnormal workpieces are relatively rare and can be removed manually. The sensor 65 can also be connected to the machine tool controller to alert the worker on the machine tool control screen that there is an abnormal workpiece.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
