Description

Technical Field

[0001] The utility model relates to the field of bearing assembly, and specifically relates to a separating device for unqualified bearings. Background Technique

[0002] After the bearings are assembled, they need to be boxed and transported. Before boxing, the bearings generally need to be inspected to pick out the damaged or unqualified assembled bearings. The existing method is generally manual selection, which has low efficiency and large workload. Long-term focused viewing is likely to cause fatigue, which may lead to the situation that unqualified bearings are not separated in time, affecting the qualification rate of bearings. The existing improved device uses structures such as air cylinders to automatically remove the unqualified bearings detected on the conveyor belt. However, it is found in actual application that when some unqualified bearings are pushed by structures such as air cylinders and move from the conveyor belt, the exposed cage on the unqualified assembled bearings is very likely to scratch the conveyor belt, affecting the normal movement and transportation of the bearings, and there are great inconveniences in actual application. Content of the Utility Model

[0003] The purpose of the utility model is to provide a separating device for unqualified bearings, which can solve the technical problem that the existing device for separating unqualified bearings is likely to scratch the conveyor belt during use, so that the unqualified bearings on the conveyor belt will not contact the conveyor belt too much during separation, reducing the possible damage to the conveyor belt during the separation process, ensuring the normal movement and transportation of the bearings, and improving the efficiency and convenience of separating unqualified bearings.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] A separating device for unqualified bearings includes a conveyor belt for conveying bearings. A storage groove is provided on one side of the conveyor belt. A bracket is provided above the conveyor belt. A rotating shaft is rotatably connected to the bracket. A plurality of operating rods are arrayed on the side surface of the rotating shaft. A suction plate for cooperating with the bearings is slidably connected to the end of the operating rod. An expansion rod for driving the suction plate to slide is provided on the operating rod. A roller is rotatably connected to the bracket. A trigger electrically connected to the expansion rod is provided on the operating rod. When the operating rod rotates, the roller rolls into contact with the trigger.

[0006] Further, an electromagnet is provided inside the suction plate. The electromagnet is electrically connected to the trigger. The suction plate is magnetically attracted to the bearings.

[0007] Further, the trigger includes an L-shaped elastic sheet. Contacts electrically connected to the expansion rod are provided on both the vertical part and the horizontal part of the L-shaped elastic sheet. When the L-shaped elastic sheet is compressed by the roller, the two contacts come into contact.

[0008] Further, a fixed disk is provided on the bracket, and the roller is rotatably connected to the position above the bearing on the fixed disk.

[0009] Further, a groove is provided on one side of the operating rod facing the fixed disk, the trigger is arranged in the groove, and after the roller extends into the interior of the groove, it is in rolling contact with the trigger.

[0010] Further, a frame is provided on the side of the conveyor belt, a notch is provided on the frame, and the storage groove is communicated with the notch.

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

[0012] 1. The structure of the present utility model is provided with a bracket above the conveyor belt. A rotating shaft is rotatably arranged on the bracket, and a plurality of operating rods are arrayed on the side of the rotating shaft. A suction plate used in cooperation with the bearing is slidably connected to the end of the operating rod. When detecting unqualified bearings, such a structure drives a plurality of operating rods to rotate by using the rotating shaft. When the operating rod rotates above the bearing, the telescopic rod is used to drive the suction plate at the end of the operating rod to slide, so that the suction plate contacts the bearing and is suction-fixed to it. The telescopic rod drives the operating rod to retract, thereby separating the bearing from the conveyor belt. Then, the rotating shaft is used to continue driving the operating rod to rotate by a certain angle, and the suction plate is separated from the bearing. Under the action of inertia, the bearing is thrown into the storage groove on the side, so that the unqualified bearings on the conveyor belt do not come into frictional contact with the conveyor belt during the separation process, thereby avoiding possible scratches on the conveyor belt caused by the exposed cage on the bearing, ensuring the integrity of the conveyor belt, and ensuring the efficiency and convenience of bearing separation;

[0013] 2. A roller is rotatably arranged on the bracket, and a trigger electrically connected to the telescopic rod is arranged on the operating rod. When the operating rod rotates above the bearing, the roller is in rolling contact with the trigger. Such a structure does not require separate control of the telescopic movement of the telescopic rod. When the operating rod rotates above the bearing, the trigger on the operating rod contacts the roller and is squeezed by it to generate an electrical signal, thereby driving the telescopic rod electrically connected to it to automatically extend, so that the suction plate contacts the bearing. Then, the telescopic rod retracts to drive the bearing to be separated from the conveyor belt. Such a structure improves the convenience of controlling the telescopic rod, reduces possible systematic errors, and improves the accuracy of separating unqualified bearings.

[0021] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0022] Refer to Figure 1 and Figure 2, the present utility model relates to a separation device for unqualified bearings 1. The main structure includes a conveyor belt 2 for conveying the bearings 1. Generally, an existing belt conveyor can be used for the conveyor belt 2. The bearings 1 are placed on the conveyor belt 2 to achieve batch movement and transportation of the bearings 1. A storage tank 3 is provided on one side of the conveyor belt 2. The storage tank 3 has a structure with an open top and side, and is used to put the unqualified bearings 1 into the storage tank 3 from the open side, so as to realize the separation operation from the qualified bearings 1 on the conveyor belt 2. Above the conveyor belt 2, there is a bracket 4 welded or bolted. The bracket 4 is fixed on the body of the conveyor belt 2 or the ground. A rotating shaft 5 is rotatably connected to the bracket 4 through a bearing 1. The rotating shaft 5 is driven to rotate by a motor. A plurality of operating rods 6 are arranged in an array on the side of the rotating shaft 5 by welding or bolting. The operating rods 6 extend along the radial direction of the rotating shaft 5. A suction plate 7 cooperating with the bearing 1 is slidably connected to the end of the operating rod 6. The suction plate 7 slides along the length direction of the operating rod 6. After sliding towards the bearing 1, it contacts and sucks the bearing 1, and then the bearing 1 can be lifted from the conveyor belt 2. Under the rotational movement of the operating rod 6, the unqualified bearing 1 makes an arc movement and separates from the conveyor belt 2. There is no contact friction with the conveyor belt 2 during the separation process, thus avoiding the possible scratching of the conveyor belt 2 by the exposed cage on the unqualified assembled bearing 1, ensuring the normal operation of the conveyor belt 2, reducing the probability of shutdown for maintenance, and improving the convenience and efficiency of separating and processing the unqualified bearings 1. An expansion rod 8 for driving the suction plate 7 to slide is provided on the operating rod 6. Specifically, an electric cylinder or a pneumatic cylinder can be used. The suction plate 7 is welded or bolted to the movable end of the expansion rod 8, and the expansion and contraction movement of the expansion rod 8 is used to drive the suction plate 7 to slide. A roller 9 is rotatably connected to the bracket 4 through a bearing 1. A trigger electrically connected to the expansion rod 8 is provided on the operating rod 6. After being triggered, the trigger can generate an electrical signal, thereby causing the expansion rod 8 electrically connected to it to perform an expansion and contraction movement. When the operating rod 6 rotates, the roller 9 makes rolling contact with the trigger. Such a structure makes the triggering mode of the trigger be the extrusion contact of the roller 9, so that when the operating rod 6 rotates above the unqualified bearing 1, the trigger is automatically triggered after being extruded by the roller 9, and then the expansion rod 8 is driven to perform an expansion and contraction movement, so as to realize the sliding of the suction plate 7 and the contact and suction of the bearing 1. There is no need to separately control the expansion and contraction movement of the expansion rod 8, which simplifies the complexity of the device, avoids the situation of omission in the separation of unqualified bearings 1 caused by system errors, and improves the accuracy of the separation operation of unqualified bearings 1.

[0023] Preferably, an electromagnet 10 is provided inside the suction plate 7. The electromagnet 10 can adopt any structure with magnetism after being energized in the existing market. The electromagnet 10 is electrically connected to a trigger. When the trigger is triggered, the circuit where the electromagnet 10 is located is turned on, so that the electromagnet 10 has magnetism after being energized. The suction plate 7 is magnetically attracted to the bearing 1. With such a structure, when the operating rod 6 rotates above the unqualified bearing 1, the telescopic rod 8 drives the bearing 1 to slide. After the suction plate 7 generates magnetism under the action of the electromagnet 10, it is magnetically attracted to the bearing 1. Before the roller 9 separates from the trigger, the suction plate 7 remains magnetically attracted to the bearing 1. After the roller 9 separates from the trigger, the electromagnet 10 is powered off automatically, so that the suction plate 7 separates from the bearing 1. Under the action of inertia, the bearing 1 is thrown into the storage groove 3, which makes it more convenient to control the contact or separation between the suction plate 7 and the bearing 1.

[0024] Preferably, referring to Figure 4 and Figure 5 , the trigger includes an L-shaped elastic piece 11. The L-shaped elastic piece 11 is made of an elastic metal material and can automatically reset after being compressed. Contacts 12 electrically connected to the telescopic rod 8 are provided on both the vertical part and the horizontal part of the L-shaped elastic piece 11. When the L-shaped elastic piece 11 is compressed by the roller 9, the two contacts 12 come into contact. During the process that the roller 9 contacts and drives the L-shaped elastic piece 11 to bend, the two contacts 12 come into contact, and thus an electrical signal can be generated. The specific structure can refer to the structure of a contact sensor in the existing market. After generating the electrical signal, it can prompt the telescopic rod 8 electrically connected to it to perform telescopic movement. When the roller 9 separates from the L-shaped elastic piece 11, the two contacts 12 separate, and thus the electrical signal disappears, and the trigger is in an off state, preparing for the next telescopic drive.

[0025] Preferably, a fixed disk 13 is welded or bolted to the bracket 4. The roller 9 is rotatably connected to the fixed disk 13 through a bearing 1 at a position above the bearing 1. Such a structure makes the installation position of the roller 9 more stable and accurate, provides a more stable support for the roller 9, and ensures the accuracy of its cooperation with the trigger on the operating rod 6 rotating above the bearing 1.

[0026] Preferably, referring to Figure 3 , a groove 14 is provided on one side of the operating rod 6 facing the fixed disk 13. The groove 14 is recessed from the surface of the operating rod 6. The trigger is welded or bolted to be arranged in the groove 14. After the roller 9 extends into the inside of the groove 14, it is in rolling contact with the trigger. Such a structure makes the trigger hidden in the groove 14 and will not contact external objects when the operating rod 6 rotates to other positions. Thus, it ensures that the trigger remains in an off state and is not prone to accidental touch, and ensures the accuracy of the cooperation between the trigger and the roller 9.

[0027] Preferably, a frame 15 is provided on the side of the conveyor belt 2, and the conveyor belt 2 is arranged on the frame 15. An opening 16 is provided on the frame 15, and the opening 16 penetrates through the frame 15. The storage groove 3 is communicated with the opening 16. The arrangement of the opening 16 enables the operating rod 6 to pass through the opening 16 when rotating, avoiding the possible movement interference between the operating rod 6 and the frame 15. At the same time, the unqualified bearing 1 adsorbed by the suction plate 7 can also pass through the opening 16 during the process of being thrown into the storage groove 3, thereby preventing the bearing 1 from falling outside the storage groove 3 and improving the accuracy of separating and storing the unqualified bearing 1.

[0028] Working principle: The structure of the present utility model is provided with a bracket 4 above the conveyor belt 2. A rotating shaft 5 is rotatably arranged on the bracket 4. A plurality of operating rods 6 are arranged in an array on the side surface of the rotating shaft 5. A suction plate 7 used in cooperation with the bearing 1 is slidably connected to the end of the operating rod 6. When an unqualified bearing 1 is detected, such a structure drives a plurality of operating rods 6 to rotate by using the rotating shaft 5. When the operating rod 6 rotates above the bearing 1, the telescopic rod 8 is used to drive the suction plate 7 at the end of the operating rod 6 to slide, so that the suction plate 7 contacts and is suction-fixed to the bearing 1 after contacting the bearing 1. The telescopic rod 8 drives the operating rod 6 to retract, thereby separating the bearing 1 from the conveyor belt 2. Then, after the rotating shaft 5 continues to drive the operating rod 6 to rotate by a certain angle, the suction plate 7 is separated from the bearing 1. Under the action of inertia, the bearing 1 is thrown into the storage groove 3 on the side, so that the unqualified bearing 1 on the conveyor belt 2 does not come into frictional contact with the conveyor belt 2 during the separation process, thereby avoiding the possible scratching of the conveyor belt 2 caused by the exposed cage on the bearing 1, ensuring the integrity of the conveyor belt 2, and ensuring the efficiency and convenience of separating the bearing 1; A roller 9 is rotatably arranged on the bracket 4. A trigger electrically connected to the telescopic rod 8 is provided on the operating rod 6. When the operating rod 6 rotates above the bearing 1, the roller 9 comes into rolling contact with the trigger. Such a structure does not require separate control of the telescopic movement of the telescopic rod 8. When the operating rod 6 rotates above the bearing 1, the trigger on the operating rod 6 contacts the roller 9 and generates an electrical signal after being squeezed by it, thereby driving the telescopic rod 8 electrically connected to it to automatically extend, so that the suction plate 7 contacts the bearing 1. Then, the telescopic rod 8 retracts to drive the bearing 1 to be separated from the conveyor belt 2. Such a structure improves the convenience of controlling the telescopic rod 8, reduces the possible systematic error, and improves the accuracy of separating the unqualified bearing 1.
