Technical Field
[0001] This utility model relates to the field of needle roller bearing processing technology, specifically a needle roller bearing assembly mechanism. Background Technology
[0002] Needle roller bearings are a type of roller bearing with slender needle-shaped rollers and extremely small radial cross-sectional dimensions. They can withstand high radial loads within a limited space. The needles make line contact with the raceway surface, and compared to ball bearings, they can withstand greater impacts and heavy loads. They also have a compact structure and are commonly used in gearboxes, universal joints, and other parts of automobiles, machine tools, and other equipment.
[0003] When machining and assembling needle roller bearings, first place the container containing the needle rollers and the workpiece holding the needle rollers on the operating table. Then, place the needle rollers into the workpiece one by one. Gradually rotate the inner ring of the workpiece to move the needle rollers into the workpiece to ensure that their spacing is consistent to avoid jamming during operation. Use positioning fixtures to ensure coaxiality. Finally, after clearance detection and sealing treatment, complete the overall assembly to ensure that the bearing rotates flexibly and has good sealing performance.
[0004] In the machining and assembly of needle roller bearings, the workpiece to which the needle rollers need to be placed is first placed on the operating table and then the needle rollers are filled in. During assembly, the workpiece and the needle rollers need to be supported multiple times before they can be assembled, which increases the adjustment time during assembly.

Detailed Implementation
[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a needle roller bearing assembly mechanism includes an operating table 1, with an adjustment component 11 on the top of the operating table 1; a placement plate 12 is fixedly connected to the side wall of the adjustment component 11; a placement hole 13 is opened in the middle of the placement plate 12; a pair of clamping plates 14 are fixedly connected to the surface of the adjustment component 11; the clamping plates 14 are located above the placement plate 12; a placement box 15 is fixedly connected to the middle of the operating table 1; the placement box 15 is located below the placement plate 12; the clamping plates 14 are elastic; during operation, the workpiece is first placed into the placement hole 13, and during placement, it will contact the clamping plates 14. Upon contact, the pair of clamping plates 14 will be pushed to both sides, causing them to move to the sides. After movement, the clamping plates 14 will be in close contact with the workpiece, making... It clamps and fixes the workpiece, and then the needle rollers inside the placement box 15 can be taken out and placed into the workpiece one by one. At the same time, the clamping plate 14 only clamps the outer ring of the workpiece. At this time, the inner ring inside can also rotate. After the needle rollers are installed, they can be rotated to move the needle rollers. In this way, fixing the workpiece reduces the inconvenience when the workpiece and the needle rollers need to be operated at the same time, and fixing the outer ring of the workpiece increases the hand operation space. By adding the placement hole 13, positioning can be added when placing the workpiece. At the same time, when the clamping plate 14 squeezes the workpiece, it can increase the contact area of the workpiece above the placement hole 13, making it more stable when fixed. When installing the workpiece, the clamping plate 14 can be used to quickly fix the workpiece by utilizing the elasticity of the clamping plate 14, making it more convenient for installation and disassembly.
[0026] like Figure 5 As shown, a feed plate 2 is fixedly connected to the side wall of the operating table 1; an airbag 21 is fixedly connected to the end of the feed plate 2; a connection port 22 is provided on the top of the airbag 21; during operation, after the workpiece and needle roller are installed, the workpiece can be placed on the feed plate 2, and then it will slide along the surface of the feed plate 2, moving closer to the airbag 21. Before the assembly begins, the connection port 22 is connected to an air pump to fill the airbag 21 with gas, so that it can increase the cushioning when the workpiece slides down when it comes into contact with the workpiece; by adding the feed plate 2, the dwell time of the workpiece on the operating table 1 can be reduced after the workpiece is assembled, thereby increasing the operating space on the surface of the operating table 1. At the same time, the airbag 21 can increase the flexible contact when the workpiece moves to the bottom, thereby reducing collisions.
[0027] like Figure 1 As shown, a guide plate 3 is fixedly connected to the top of the placement box 15; the guide plate 3 and the placement hole 13 are correspondingly arranged; during operation, when the needle roller is picked up and placed into the workpiece, some needle rollers will fall. At this time, the falling needle rollers will contact the guide plate 3 when they fall, so that they gradually enter the placement box 15 through the guidance of the guide plate 3; by adding the guide plate 3, the time for the needle rollers to enter the placement box 15 can be accelerated by contacting the guide plate 3 when they fall, and the number of needle rollers falling to the outside can be reduced.
[0028] like Figures 2 to 4As shown, a pair of sliding grooves 4 are formed on the surface of the placement plate 12; a sliding rod 41 is slidably connected inside the sliding groove 4; the sliding rod 41 and the clamping plate 14 are fixedly connected; a first fixing hole 42 is formed on the surface of both the placement plate 12 and the sliding rod 41; during operation, when the workpiece is placed, the workpiece will push the clamping plate 14 to drive the sliding rod 41 to slide inside the sliding groove 4. After installation, the sliding rod 41 is moved to align with the first fixing hole 42. At this time, a pin can be inserted into the first fixing hole 42, so that it enters the sliding rod 41 through the first fixing hole 42, thereby fixing the clamping plate 14 and making it more stable after clamping the workpiece; by adding the sliding rod 41, the stability after stopping can be increased when using the clamping plate 14 to clamp and fix the workpiece, thus making it more stable during use and reducing the adjustment operation during assembly.
[0029] like Figure 4 As shown, a first hook 5 is fixedly connected to one end of the clamping plate 14; a second hook 51 is fixedly connected to the other end of the clamping plate 14. During operation, when the workpiece is placed into the placement hole 13, the clamping plate 14 is squeezed. After the workpiece is placed, it will be in close contact with the clamping plate 14. At this time, the first hook 5 can be pulled closer to the second hook 51, and then they will make contact and engage, connecting the pair of clamping plates 14. At this time, the slide rod 41 is in the corresponding position with the first fixing hole 42. Then, the pin can be inserted into the first fixing hole 42 to fix the slide rod 41, thereby increasing the contact between the clamping plate 14 and the workpiece. By adding the first hook 5 and the second hook 51, the clamping plate 14 and the workpiece can have more contact after the workpiece is placed, making them fit better. At the same time, when fixing in the first fixing hole 42, the workpiece can reach the designated position more quickly.
[0030] like Figures 1 to 3 As shown, the adjustment component 11 includes a fixing block 6; a slider 61 is slidably connected to the middle of the fixing block 6; the slider 61 and the placement plate 12 are fixedly connected; both the fixing block 6 and the slider 61 have second fixing holes 62 on their surfaces; multiple second fixing holes 62 are provided on the slider 61; during operation, after the workpiece is placed, the pin inside the second fixing hole 62 can be pulled out according to the operator's situation to pull the slider 61 and adjust the position of the placement plate 12, so that the position of the placement plate 12 can be adjusted for different operators, thereby adapting to the working conditions of different operators; by adding slider 61 and thus adjusting the position of placement plate 12, the flexibility of operation can be increased, allowing it to quickly adapt to different operators, thereby increasing the convenience of operation.
[0031] Working principle: First, the workpiece is placed into the placement hole 13. During placement, it will contact the clamping plate 14, pushing the clamping plate 14 to both sides. After movement, the clamping plate 14 will be in close contact with the workpiece, clamping and fixing it. Then, the needle rollers inside the placement box 15 can be taken out and placed into the workpiece one by one. At the same time, the clamping plate 14 only clamps the outer ring of the workpiece, while the inner ring can still rotate. After the needle rollers are installed, they can be rotated to move the needle rollers. This fixation of the workpiece reduces the need for simultaneous operation of the workpiece and the needle rollers. To address the inconvenience of manual operation, the outer ring of the workpiece is fixed to increase hand operating space. After the workpiece and needle rollers are installed, the workpiece can be placed on the feed plate 2, and then it will slide along the surface of the feed plate 2, moving closer to the airbag 21. Before assembly begins, the connection port 22 is connected to the air pump to fill the airbag 21 with gas, which increases the cushioning when the workpiece slides and falls upon contact. When the needle rollers are picked up and placed inside the workpiece, some needle rollers will fall. At this time, the falling needle rollers will contact the guide plate 3, and gradually enter the placement box 1 under the guidance of the guide plate 3. 5. Internally; When the workpiece is placed, it pushes the clamping plate 14, causing the slide rod 41 to slide inside the slide groove 4. After installation, the slide rod 41 is moved to align with the first fixing hole 42. At this time, a pin can be inserted into the first fixing hole 42, allowing it to enter the slide rod 41 through the first fixing hole 42, thereby fixing the clamping plate 14 and making it more stable after clamping the workpiece. When the workpiece is placed into the placement hole 13, it will press against the clamping plate 14. At this time, the workpiece will be in close contact with the clamping plate 14. At this time, the first hook 5 can be pulled towards the second hook. 51 is brought close together and then engaged to connect a pair of clamping plates 14. At this time, the slide rod 41 is in the corresponding position with the first fixing hole 42. Then, the pin can be inserted into the first fixing hole 42 to fix the slide rod 41, thereby increasing the contact between the clamping plate 14 and the workpiece. After the workpiece is placed, the pin inside the second fixing hole 62 can be pulled out according to the operator's situation to pull the slider 61 and adjust the position of the placement plate 12. This allows the position of the placement plate 12 to be adjusted for different operators, thus adapting to the working conditions of different operators.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
