Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bearing assembly equipment, and particularly to a bearing assembly tooling. Background Art
[0002] In modern manufacturing, bearings, as key components in rotating machinery, the quality of their assembly and detection is directly related to the performance and reliability of the final product. Traditional bearing assembly methods often rely on manual operation or semi-automatic equipment, which have problems of low efficiency, insufficient accuracy, and are difficult to ensure consistent product quality.
[0003] When performing airtightness testing on bearings, traditional methods usually need to consider the directionality of the bearings, that is, the bearings must be adjusted to a specific position to conduct effective testing, which not only increases the operation complexity but also prolongs the detection time. Existing bearing fixing devices usually cannot provide sufficient stability and are prone to sliding or displacement during the assembly process, resulting in assembly failure or the need for rework, thus affecting production efficiency. Moreover, due to different sizes and types of bearings requiring different assembly processes, higher requirements are put forward for the adaptability and flexibility of the tooling. Summary of the Invention
[0004] Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a bearing assembly tooling, mainly to solve the problems of insufficient safety accuracy, time-consuming detection, and poor adaptability in bearing assembly.
[0005] Technical Solutions To achieve the above object, the present invention provides the following technical solutions: A bearing assembly tooling includes a fixed frame. The inner wall of the fixed frame is fixedly connected with a connecting plate. The top surface of the connecting plate is fixedly connected with four connecting rods. The top ends of the four connecting rods are fixedly connected with a top plate. The top surface of the connecting plate is fixedly connected with two slide rails. A placement table is slidably connected to the surfaces of the two slide rails. A transfer mechanism for lifting the product to be detected is arranged at the rear side of the connecting plate; The transfer mechanism includes a placement box fixedly connected to the side surface of the connecting plate. Three fixing blocks and a placement plate are fixedly connected to the inner wall of the placement box; A fixing mechanism for fixing the product placed on the surface of the placement table is arranged above the connecting plate; The lower side of the connecting plate is provided with a detection mechanism that can detect the products placed on the placement table. In this solution, the transfer mechanism is used to transfer the products to be detected from the placement box one by one, and then the products are placed on the surface of the placement table and wait for the fixing mechanism to fix them to prevent slipping during the air tightness detection process. Then, the air tightness is detected by the detection mechanism, and both the left and right sides of the detection mechanism can be detected, so the orientation of the product can be ignored, thereby improving the efficiency of detection; Furthermore, a vibration motor is fixedly connected to the bottom surface of the placement plate, a lifting frame is slidably connected to the inner wall of the placement box, and the lifting frame is staggered with three fixed blocks. After the products are uniformly poured onto the surface of the placement plate, the products can be lifted one by one by repeatedly staggering the three fixed blocks and the lifting frame.
[0006] Furthermore, the inner wall of the placement box is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to a rotating rod, the side end of the rotating rod is rotatably connected to a rotating block, a slot is provided on the side of the lifting frame, and the rotating block is rotatably engaged with the inner wall of the slot. After starting the first motor, the output shaft of the first motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating block to rotate in a circle, and then, under the engaging effect of the slot and the rotating block, the lifting frame can be driven to repeatedly lift up and down on the inner wall of the placement box. When the lifting frame is displaced to the lowermost side, the product can be moved from the bottom to the intersection of the lifting frame and the fixed block on the far right. As the lifting frame is lifted, the product can be transferred to the junction of the fixed block and the lifting frame on the middle side, and finally the product is lifted to the lifting frame at the highest point. Since the surface of the placement table is concave, the product directly slides to the lowest surface of the placement table at this time.
[0007] Furthermore, the fixing mechanism includes a first telescopic pole, which is installed on the top surface of the top plate, and the output shaft of the first telescopic pole slides through the bottom surface of the top plate. The output shaft of the first telescopic pole is fixedly connected with a connecting block, and the top surface of the connecting block is fixedly connected with two limit rods, and the two limit rods both slide through the top surface of the top plate, and the bottom surface of the connecting block is fixedly connected with a fixed pressure block. When a product is transferred to the surface of the placement table, the first telescopic pole is started, and the output shaft of the first telescopic pole drives the connecting block to move downward, and then the fixed pressure block moves downward at the same time to fix the product on the surface of the placement table. The setting of the two limit rods makes the fixed pressure block more stable during the falling process.
[0008] Further, the detection mechanism includes a vertical rod fixedly connected to the inner wall of the fixed frame. A second telescopic electric rod is fixedly connected to the surface of the vertical rod. The extension shaft of the second telescopic electric rod is fixedly connected with a movable hinge shaft. The top surface of the vertical rod is rotatably connected with a turntable. Two curved rods are rotatably connected to the surface of the turntable. Sliders are rotatably connected to the remote ends of the two curved rods. When the product is placed on the surface of the placement table and is pressed by the fixed pressing block, the second telescopic electric rod is started. The output shaft of the second telescopic electric rod drives the movable hinge shaft to displace. After the displacement of the movable hinge shaft, it drives a slider fixedly connected thereto to slide. And the slider is simultaneously affected by one of the curved rods and the turntable. Subsequently, the turntable rotates to drive the other slider and the curved rod to slide synchronously, so that the two detection pressing blocks displace synchronously and in opposite directions.
[0009] Further, a fixed seat is fixedly connected to the bottom surface of the connecting plate. The two sliders are both slidably connected to the inner wall of the fixed seat. The movable hinge shaft is fixedly connected with one of the sliders. After the displacement of the movable hinge shaft, it drives a slider fixedly connected thereto to slide.
[0010] Further, detection pressing blocks are fixedly connected to the top surfaces of the two sliders. Two sliding grooves are formed in the top surface of the connecting plate. The two sliders are respectively slidably connected to the inner walls of the two sliding grooves. The turntable rotates to drive the two sliders and the two curved rods to slide synchronously, so that the two detection pressing blocks displace synchronously and in opposite directions.
[0011] Further, two detection air pumps are fixedly connected to the top surface of the connecting plate. Connecting air pipes are connected to the sides of the two detection air pumps through pipelines. The two connecting air pipes are respectively connected to the two detection pressing blocks through pipelines. The settings of the two detection air pumps and the two connecting air pipes ensure that the orientation of the product is not restricted and airtightness detection can always be carried out on it, avoiding the process of manually adjusting the orientation of the product.
[0012] Further, the adjacent ends of the two detection pressing blocks are in contact connection with the top surface of the placement table. A pull ring is fixedly connected to the side surface of the placement table. Limit plates are fixedly connected to the front ends of the two slide rails. The two detection pressing blocks are in contact connection with the top surface of the placement table to prevent the two detection pressing blocks from bumping against the placement table. And the setting of the pull ring can facilitate the outward extraction of the placement table after the product detection is completed. The settings of the two limit plates prevent the placement table from being pulled out of the range of the two slide rails when the placement table is extracted.
[0013] Further, the placement plate is in a slope surface. The top surfaces of the three fixed blocks are all in slope surfaces. The top surface of the lifting frame is in a slope surface and the highest position is flush with the top surface of the placement box. The top surface position of the highest position of the lifting frame is flush with the placement table. The slope surface of the placement plate facilitates the stacking of products at the bottom end.
[0014] Beneficial effects Compared with the prior art, the present invention provides a bearing assembly tooling, which has the following beneficial effects: 1. Through the integrated fixing mechanism, the bearing can be ensured to be stable and immovable during the detection or assembly process. The first telescopic electric rod drives the fixed pressing block to descend, tightly pressing the bearing to prevent it from sliding or shifting, thus ensuring the safety and precision of the operation and enabling the subsequent assembly steps to proceed smoothly.
[0015] 2. The design of the detection mechanism realizes the two-way airtightness test function without considering the bearing directionality. The operation of the second telescopic electric rod makes the movable hinge shaft move, which in turn drives the two curved rods and the sliders to move synchronously in opposite directions, enabling the two detection pressing blocks to act on different sides of the bearing simultaneously for all-round detection. This design avoids the time required for adjusting the product orientation, further improves the detection efficiency, and ensures that all bearings can be subject to consistent quality control standards.
[0016] 3. The entire tooling structure is compact, and the coordinated work among components is smooth. For example, the slope surface design of the placement plate and the slope surface cooperation of the fixed block and the lifting frame help the bearing to naturally slide to the predetermined position on the placement table; while the connection between the detection air pump and the detection pressing block ensures the uniformity and accuracy of the pressure application. These optimizations in details jointly promote the specialization and high efficiency of the bearing assembly process. Description of the drawings

[0022] Refer to Figures 1 - 7, the present invention provides a bearing assembly tooling, including a fixed frame 1. The inner wall of the fixed frame 1 is fixedly connected with a connecting plate 2. The top surface of the connecting plate 2 is fixedly connected with four connecting rods 3. The top ends of the four connecting rods 3 are fixedly connected with a top plate 4. The top surface of the connecting plate 2 is fixedly connected with two slide rails 9. A placing table 10 is slidably connected to the surfaces of the two slide rails 9. A transfer mechanism for lifting the product to be detected is arranged at the rear side of the connecting plate 2; The transfer mechanism includes a placing box 20. The placing box 20 is fixedly connected to the side surface of the connecting plate 2. The inner wall of the placing box 20 is fixedly connected with three fixing blocks 25 and a placing plate 21; A fixing mechanism for fixing the product placed on the surface of the placing table 10 is arranged above the connecting plate 2; A detection mechanism for detecting the product placed on the surface of the placing table 10 is arranged below the connecting plate 2. In this solution, the transfer mechanism is used to transfer the products to be detected from the placing box 20 one by one, and then the products are placed on the surface of the placing table 10 and wait for the fixing mechanism to fix them to prevent slipping during the airtightness detection. Subsequently, the airtightness of the products is detected by the detection mechanism, and both the left and right sides of the detection mechanism can detect, so the orientation of the products can be ignored, thereby improving the detection efficiency; Among them, a vibration motor 22 is fixedly connected to the bottom surface of the placing plate 21. A lifting frame 26 is slidably connected to the inner wall of the placing box 20. The lifting frame 26 is alternately connected with the three fixing blocks 25. After the products are uniformly poured on the surface of the placing plate 21, by using the repeated alternation of the three fixing blocks 25 and the lifting frame 26, the products can be lifted one by one.
[0023] Among them, a first motor 23 is fixedly connected to the inner wall of the placing box 20. The output shaft of the first motor 23 is fixedly connected with a rotating rod 24. A rotating clamping block 28 is rotatably connected to the side end of the rotating rod 24. A clamping groove 27 is formed on the side surface of the lifting frame 26. The rotating clamping block 28 is rotatably clamped in the inner wall of the clamping groove 27. After the first motor 23 is started, the output shaft of the first motor 23 drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the rotating clamping block 28 to perform a circular rotation. Subsequently, under the clamping effect of the clamping groove 27 and the rotating clamping block 28, the lifting frame 26 can be driven to repeatedly move up and down in the inner wall of the placing box 20. When the lifting frame 26 moves to the lowest side, the product can be moved from the bottom to the intersection of the lifting frame 26 and the rightmost fixing block 25. As the lifting frame 26 is lifted, the product can be transferred to the intersection of the middle fixing block 25 and the lifting frame 26, and finally the product is lifted to the highest lifting frame 26. Since the surface of the placing table 10 is concave, the product directly slides to the lowest surface of the placing table 10 at this time.
[0024] Among them, the fixing mechanism includes a first telescopic electric rod 5. The first telescopic electric rod 5 is installed on the top surface of the top plate 4. The output shaft of the first telescopic electric rod 5 slides through the bottom surface of the top plate 4. The output shaft of the first telescopic electric rod 5 is fixedly connected with a connecting block 6. Two limiting rods 7 are fixedly connected to the top surface of the connecting block 6. Both of the two limiting rods 7 slide through the top surface of the top plate 4. A fixing pressure block 8 is fixedly connected to the bottom surface of the connecting block 6. When a product is transferred to the surface of the placing table 10, the first telescopic electric rod 5 is started. The output shaft of the first telescopic electric rod 5 drives the connecting block 6 to move downward. Immediately, the fixing pressure block 8 also moves downward to fix the product on the surface of the placing table 10. The setting of the two limiting rods 7 makes the fixing pressure block 8 more stable during the falling process.
[0025] Among them, the detection mechanism includes a vertical rod 14. The vertical rod 14 is fixedly connected to the inner wall of the fixing frame 1. A second telescopic electric rod 15 is fixedly connected to the surface of the vertical rod 14. The extension shaft of the second telescopic electric rod 15 is fixedly connected with a movable hinge shaft 16. The top surface of the vertical rod 14 is rotatably connected with a turntable 18. Two curved rods 17 are rotatably connected to the surface of the turntable 18. Sliders 1601 are rotatably connected to the far ends of the two curved rods 17 away from each other. When the product is placed on the surface of the placing table 10 and is pressed by the fixing pressure block 8, the second telescopic electric rod 15 is started. The output shaft of the second telescopic electric rod 15 drives the movable hinge shaft 16 to move. After the movable hinge shaft 16 moves, it drives a slider 1601 fixedly connected to it to slide. And the slider 1601 is simultaneously affected by one of the curved rods 17 and the turntable 18. Subsequently, the turntable 18 rotates to drive the other slider 1601 and the curved rod 17 to slide synchronously, so that the two detection pressure blocks 19 move synchronously and in opposite directions.
[0026] Among them, a fixed seat 13 is fixedly connected to the bottom surface of the connecting plate 2. Both of the two sliders 1601 are slidably connected to the inner wall of the fixed seat 13. The movable hinge shaft 16 is fixedly connected with one of the sliders 1601. After the movable hinge shaft 16 moves, it drives a slider 1601 fixedly connected to it to slide.
[0027] Among them, detection pressure blocks 19 are fixedly connected to the top surfaces of the two sliders 1601. Two sliding grooves 1901 are formed in the top surface of the connecting plate 2. The two sliders 1601 are respectively slidably connected to the inner walls of the two sliding grooves 1901. The turntable 18 rotates to drive the two sliders 1601 and the two curved rods 17 to slide synchronously, so that the two detection pressure blocks 19 move synchronously and in opposite directions.
[0028] Among them, two detection air pumps 2101 are fixedly connected to the top surface of the connecting plate 2. Connecting air pipes 2102 are connected to the sides of the two detection air pumps 2101 through pipes. The two connecting air pipes 2102 are respectively connected to the two detection pressure blocks 19 through pipes. The settings of the two detection air pumps 2101 and the two connecting air pipes 2102 ensure that the orientation of the product is not restricted, and the airtightness of the product can always be detected, avoiding the process of manually adjusting the orientation of the product.
[0029] Among them, the closer ends of the two detection pressure blocks 19 are in contact with the top surface of the placement table 10. A pull ring 11 is fixedly connected to the side of the placement table 10. Limit plates 12 are fixedly connected to the front ends of the two slide rails 9. The two detection pressure blocks 19 are in contact with the top surface of the placement table 10 to prevent the two detection pressure blocks 19 from colliding with the placement table 10. The setting of the pull ring 11 facilitates the outward extraction of the placement table 10 after the product detection is completed. The setting of the two limit plates 12 prevents the placement table 10 from being pulled out of the range of the two slide rails 9 when the placement table 10 is extracted.
[0030] Among them, the placement plate 21 is in the shape of an inclined plane, the top surfaces of the three fixing blocks 25 are in the shape of inclined planes, the top surface of the lifting frame 26 is in the shape of an inclined plane, and the highest position is flush with the top surface of the placement box 20. The top surface of the highest position of the lifting frame 26 is flush with the placement table 10. The inclined shape of the placement plate 21 facilitates the stacking of products at the bottom end.
[0031] The working principle of the present invention: First, uniformly pour the products into the interior of the placement box 20. After starting the first motor 23, the output shaft of the first motor 23 drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the rotating chuck 28 to perform a circular rotation. Subsequently, due to the clamping effect of the card slot 27 and the rotating chuck 28, the lifting frame 26 can be driven to repeatedly move up and down on the inner wall of the placement box 20. When the displacement of the lifting frame 26 reaches the lowest side, the products can be moved from the bottom to the intersection of the lifting frame 26 and the rightmost fixed block 25. As the lifting frame 26 is lifted, the products can be transferred to the intersection of the middle fixed block 25 and the lifting frame 26, and finally the products are lifted to the highest lifting frame 26. Since the surface of the placement table 10 is concave, at this time the products directly slide to the lowest surface of the placement table 10. When products are transferred to the surface of the placement table 10, start the first telescopic electric rod 5. The output shaft of the first telescopic electric rod 5 drives the connecting block 6 to move downward, and immediately the fixed pressing block 8 also moves downward to fix the products on the surface of the placement table 10. When the products are placed on the surface of the placement table 10 and are pressed by the fixed pressing block 8, start the second telescopic electric rod 15. The output shaft of the second telescopic electric rod 15 drives the movable hinge shaft 16 to move. After the displacement of the movable hinge shaft 16, it drives a slider 1601 fixedly connected to it to slide. And the slider 1601 is simultaneously affected by one of the curved rods 17 and the turntable 18. Subsequently, the turntable 18 rotates to drive the other slider 1601 and the curved rod 17 to slide synchronously. Finally, the two detection air pumps 2101 and the two connecting air pipes 2102 simultaneously pressurize the two detection pressing blocks 19 to detect the products. After the detection is completed, pull out the placement table 10 outward through the pull ring 11.
[0032] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0033] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
