Description

Technical Field

[0001] This utility model relates to the field of automated parts sorting equipment, and in particular to an automatic receiving and sorting turntable for shaft parts. Background Technology

[0002] Shafts, as core components of mechanical transmission systems, are widely used in the automotive, aerospace, and machine tool industries. Typical structures include stepped shafts, smooth shafts, hollow shafts, and crankshafts. These parts typically work in conjunction with bearings, gears, seals, and other supporting components to achieve power transmission, motion conversion, and support positioning functions. On automated production lines, the machining accuracy of shafts directly affects the overall machine performance; therefore, the efficiency requirements for their sorting, distribution, and directional conveying are increasingly stringent.

[0003] In existing technologies, centrifugal feeding turntables for bearings are typical equipment for sorting shaft parts. The centrifugal force generated by the rotating disc arranges the parts along the disc edge and conveys them to the discharge track, with guide plates constraining the movement path of the parts. While this type of equipment can achieve continuous feeding, it has significant limitations. The equipment has poor adaptability, can only handle parts of a single size or specific shape, and requires manual adjustment of the mechanical structure during model changes, resulting in long downtime and low efficiency. During centrifugal feeding, parts are prone to stacking due to centrifugal force, especially when handling slender or irregularly shaped shafts. This stacking can cause jamming, requiring manual intervention to clear the jams, increasing production costs. Utility Model Content

[0004] To overcome the drawbacks of stacking and jamming, this utility model provides an automatic receiving and sorting turntable for shaft parts, aiming to solve the above-mentioned shortcomings.

[0005] An automatic receiving and sorting turntable for shaft parts includes a base plate, a controller mounted on the base plate, a collection tray connected to the base plate, a conveying hopper connected to the base plate, the lower end of the conveying hopper located at the top of the collection tray, a discharge hopper connected to the top of the conveying hopper, a discharge plate tangentially connected to the outer ring of the collection tray, a height limiting plate slidably connected to the discharge plate, a pressure sensor rotatably connected inside the collection tray, a slip ring for power supply for rotation provided at the bottom of the collection tray, a motor mounted at one end of the conveying hopper located at the top of the collection tray, a material-pushing plate rotatably connected inside the conveying hopper, the shaft of the material-pushing plate being connected to the output shaft of the motor, and a spring component for smooth material discharge provided on the material-pushing plate.

[0006] Optionally, the elastic component includes a pressing plate, and the feeding plate has a movable cavity. The pressing plate is slidably connected to the movable cavity of the feeding plate. A return spring is provided in the movable cavity. One end of the return spring is connected to the feeding plate, and the other end of the return spring is connected to the pressing plate.

[0007] Optionally, a buffer pad is connected to the end of the extrusion plate away from the feed plate.

[0008] Optionally, the conveyor bucket is provided with an auxiliary plate.

[0009] Optionally, a guide plate is connected to the side of the conveying hopper, and the guide plate is located inside the collecting tray.

[0010] Optionally, a protective pad is laid in the center of the collection tray.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The spring component at the front end of the feeding plate ensures continuous feeding action. In conjunction with the pressure sensor and controller, the controller immediately stops feeding from the hopper to prevent parts from accumulating excessively in the pan and achieve smooth material discharge.

[0013] 2. Through the sliding adjustment of the height limit plate and the discharge plate, the bottom slope of the height limit plate only allows parts that meet the thickness requirements to pass through. Operators can adjust the height of the height limit plate to adapt to the sorting needs of parts with different diameters, realize the classification of multi-specification shaft parts, and improve the adaptability of the equipment.

Detailed Implementation

[0020] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0021] Example: An automatic receiving and sorting turntable for shaft parts, such as... Figures 1-5 As shown, the assembly includes a base plate 1, a controller 101, a collection tray 102, a feeding hopper 103, a conveying hopper 104, a discharge plate 105, a height limit plate 106, a pressure sensor 2, a slip ring 3, a motor 4, a feeding plate 5, and an elastic assembly. The controller 101 is mounted on the base plate 1. The collection tray 102 and the conveying hopper 104 are connected to the base plate 1. The lower end of the conveying hopper 104 is located at the top of the collection tray 102. The feeding hopper 103 is connected to the top of the conveying hopper 104. The outer ring of the collection tray 102 is tangentially connected to the controller 101. There is a discharge plate 105, which is slidably connected to a height limiting plate 106. The discharge plate 105 and the height limiting plate 106 are interference-fitted. A pressure sensor 2 is rotatably connected inside the collection tray 102. A slip ring 3 for rotational power supply is provided at the bottom of the collection tray 102. A motor 4 is installed at one end of the conveying bucket 104 located at the top of the collection tray 102. A material-pushing plate 5 is rotatably connected inside the conveying bucket 104. The rotating shaft of the material-pushing plate 5 is connected to the output shaft of the motor 4. An elastic component for smooth material feeding is provided on the material-pushing plate 5.

[0022] like Figure 4 and Figure 5 As shown, the elastic component includes a return spring 7 and a pressing plate 8. The feeding plate 5 has a movable cavity 6. The pressing plate 8 is slidably connected to the movable cavity 6 of the feeding plate 5. Several return springs 7 are provided in the movable cavity 6. One end of the return spring 7 is connected to the feeding plate 5, and the other end of the return spring 7 is connected to the pressing plate 8. The return spring 7 provides a continuous rebound force, so that the pressing plate 8 can adapt to different contact angles and maintain feeding stability.

[0023] like Figure 5 As shown, it also includes a buffer pad 9. The end of the extrusion plate 8 away from the feeding plate 5 is connected to the buffer pad 9. The buffer pad 9 is made of polyurethane material that combines elasticity and wear resistance.

[0024] like Figure 4 As shown, it also includes an auxiliary plate 10. The conveying bucket 104 is covered with the auxiliary plate 10, which is made of polytetrafluoroethylene with a low coefficient of friction.

[0025] like Figure 1As shown, it also includes a guide plate 11. The guide plate 11 is connected to the side of the conveying bucket 104. The guide plate 11 is located inside the collection tray 102. The guide plate 11 has an inclined structure, and its inclined surface is in contact with the parts.

[0026] like Figure 1 As shown, it also includes a protective pad 12. The protective pad 12 is laid in the middle of the collection tray 102. The protective pad 12 is made of silicone rubber to absorb the impact of the falling parts.

[0027] Shaft-like parts of different sizes enter the conveying hopper 104 through the feeding hopper 103 and slide naturally along the inclined surface inside the hopper towards the collection tray 102. The collection tray 102 has a frustum structure in the middle, which rotates clockwise under the power supply of the bottom slip ring 3, causing the parts falling into the tray to spread outward. The pressure sensor 2 is embedded in the middle of the collection tray 102 to detect the total weight of the parts in the tray in real time. When the weight reaches a preset threshold, the sensor sends an overweight signal to the controller 101, and the controller 101 immediately controls the feeding hopper 103 to stop feeding to prevent the parts from accumulating excessively in the tray.

[0028] The feeding control is accomplished by the motor 4 driving the feeding plate 5, and the controller 101 is connected to the motor 4 via a circuit. When the motor 4 starts, it drives the feeding plate 5 to rotate inside the conveying hopper 104, moving the parts towards the collection tray 102. The low-friction auxiliary plate 10 laid at the bottom of the conveying hopper 104 ensures that the surface of the parts is not scratched during the sliding process. The buffer pad 9 at the front end of the feeding plate 5 is made of rubber. When the rear end of the part is moved, the buffer pad 9 directly pushes the part into the collection tray 102; if the buffer pad 9 contacts the top surface of the part, the extrusion plate 8 will retract into the movable cavity 6 inside the feeding plate 5, and simultaneously compress the return spring 7. It adapts to the change in contact angle through elastic deformation. After the part passes, the return spring 7 pushes the extrusion plate 8 back to its original position, maintaining the continuity of the feeding action. When the controller 101 receives an overload signal, the motor 4 immediately stops running, the feeding plate 5 stops at its current position, and the parts stop falling further, ensuring that the feeding process is precise and controllable.

[0029] After falling into the collection tray 102, the parts first come into contact with the protective pad 12, which effectively cushions the impact of the falling parts and absorbs the noise generated by the collision. The collection tray 102 continues to rotate, causing the parts to move along the inclined surface of the frustum to the edge. The inclined structure of the guide plate 11 gradually squeezes the parts to the detection area of ​​the pressure sensor 2, so that the parts are evenly distributed on the sensor surface and rotate synchronously with the tray. When the parts move to the inlet of the discharge plate 105, which is tangent to the outer ring of the collection tray 102, the sliding height limit plate 106 controls the thickness of the parts through which they pass by by adjusting the height. Parts that are too thick are blocked by the top of the inclined surface of the height limit plate 106 and continue to rotate with the tray; parts that meet the thickness requirements pass through the bottom of the height limit plate 106 and enter the discharge plate 105 to complete the sorting. The operator can manually or automatically adjust the height of the height limit plate 106 to adapt to the sorting needs of parts with different diameters. After multiple adjustments, accurate classification of parts of various specifications can be achieved.
