Description

Technical Field

[0001] This utility model belongs to the field of bearing processing technology, and in particular relates to an automatic grease injection machine for automotive bearings. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. According to the product's usage requirements, bearings must be filled with a certain amount of grease before leaving the factory.

[0003] Patent application CN202322471889.9 discloses an automatic grease injection machine for automotive bearings, comprising a processing table, a connecting frame fixedly mounted on the top of the processing table, a support base fixedly mounted on the connecting frame, a loading seat fixedly mounted on the top of the support base, a grease injection mechanism mounted on the loading seat, and an electric push rod fixedly mounted on the loading seat. The electric push rod extends to the bottom of the loading seat and a pressing cover is fixedly mounted thereon. A drive shaft is rotatably mounted on the top of the processing table, and a turning mechanism is mounted on the top of the drive shaft. A connecting ring drives a rubber pad to rotate, and as the rubber pad rotates, it drives a turning head to actuate the balls inside the bearing, causing the rollers to continuously move inside the bearing. Grease is delivered to the grease injection head through a second delivery pipe, and grease is injected into the inside of the bearing through the grease injection head. This ensures that the grease is more evenly distributed between the balls and the inner and outer rings of the bearing during the grease injection process.

[0004] Existing technologies use structures such as rubber pads to rotate the bearing, resulting in a more uniform distribution of grease between the inner and outer rings during grease injection. However, there are still shortcomings:

[0005] First, existing bearing grease injection machines can only rotate and grease bearings of a single size, which makes them impractical and unsuitable for grease injection processing of bearings of multiple sizes in actual production processes.

[0006] Secondly, existing bearing grease injection machines require the replacement of different sized drive components to rotate the bearings when performing grease injection operations on bearings of different sizes. However, the replacement of existing drive components is relatively complicated and is not conducive to the rapid progress of bearing processing. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides an automatic grease injection machine for automotive bearings. By incorporating components such as a rotating cone, this invention enables the grease injection machine to fix and perform grease injection operations on bearings of different sizes, effectively increasing the convenience of grease injection work for bearings of various sizes. Furthermore, the use of arc-shaped snap-fit ​​springs and other structures makes the replacement of the rotating cone even more convenient.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic grease injection machine for automotive bearings, comprising a worktable, a top plate above the worktable, a plurality of support blocks evenly arranged in a ring on the upper surface of the worktable, a plurality of support steps on the end face of each support block, the plurality of support steps being arranged in a stepped manner decreasing from the outside to the inside, a first motor slidably arranged above the plurality of support steps, a detachable rotating cone provided at the output end of the first motor, and a grease injection assembly provided on one side of the rotating cone.

[0009] Optionally, the grease injection assembly includes a multi-axis drive assembly disposed on the lower end face of the top plate, a fixing plate disposed at the output end of the multi-axis drive assembly, a grease injection nozzle disposed on the lower end face of the fixing plate, a storage box disposed on the upper end face of the top plate, and a flexible hose connected between the storage box and the grease injection nozzle.

[0010] Optionally, the upper end face of the rotating cone is provided with a first snap-fit ​​groove, and a snap-fit ​​block is snapped into the inside of the first snap-fit ​​groove. The snap-fit ​​block is connected to the output end of the first motor.

[0011] Optionally, each of the first snap-fit ​​grooves has a groove on its inner sidewall, and each groove has an arc-shaped snap-fit ​​spring inside. The upper end of the arc-shaped snap-fit ​​spring is fixedly connected to the inner sidewall of the groove. Each arc-shaped snap-fit ​​spring has a second snap-fit ​​groove on one side of the snap-fit ​​block. Every two adjacent arc-shaped snap-fit ​​springs and second snap-fit ​​grooves are snap-fitted together.

[0012] Optionally, each of the grease injection nozzles is provided with a collection elongated hole on the upper surface of the workbench, and each collection elongated hole is provided with a detachable collection frame on the lower surface of the workbench.

[0013] Optionally, the outer wall of the rotating cone is provided with an anti-slip protective layer.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1:

[0027] like Figure 1 , Figure 2 and Figure 3As shown, an automatic grease injection machine for automotive bearings includes a worktable 10, a top plate 11 above the worktable 10, and a plurality of support blocks 12 evenly arranged in a ring on the upper surface of the worktable 10. The plurality of support blocks 12 are arranged in a ring on the upper surface of the worktable 10. Each support block 12 has a plurality of support steps 13 on its end face. The plurality of support steps 13 are arranged in a stepped manner, decreasing in size from the outside to the inside. This allows the plurality of support steps 13 at the same horizontal height to cooperate with each other to form support platforms of different diameters. This allows the device to inject grease into bearings of different sizes without any adjustment. The bearing ring can be directly placed on the upper surface of the plurality of support steps 13 that match its size. The plurality of support steps 13 form a support and fixation for the outer ring of the bearing, thereby increasing the adaptability of the device.

[0028] A first motor 14 is slidably mounted above multiple supporting steps 13. The first motor 14 is a conventional motor, existing technology. The output end of the first motor 14 is equipped with a detachable rotating cone 16. The rotating cone 16 has an isosceles trapezoidal cross-sectional shape and is vertically positioned above the center of the multiple supporting blocks 12. The output end of the first motor 14 drives the rotating cone 16 to rotate, allowing its outer surface to contact bearing inner rings of different sizes and rotate them. This facilitates subsequent injection molding of the bearings. The grease is applied more evenly, and the downward pressure on the inner ring of the bearing by the rotating cone 16, combined with the support of the upper end of the support step 13 on the outer ring of the bearing, forms a more secure fixation for the bearing. The upper end of the top plate 11 is provided with a first push cylinder 21. The output end of the first push cylinder 21 passes through the top plate 11 and is fixedly connected to the upper end of the first motor 14. The first push cylinder 21 is a common push cylinder, which is existing technology. The output end of the first push cylinder 21 drives the first motor 14 and the rotating cone 16 and other components to move vertically, forming a downward pressure fixation for the bearing. A grease injection component is provided on one side of the rotating cone 16.

[0029] Furthermore, such as Figure 1 and Figure 3As shown, the grease injection assembly includes a multi-axis drive assembly disposed on the lower end face of the top plate 11. A fixed plate 28 is disposed at the output end of the multi-axis drive assembly, and a grease injection nozzle 29 is disposed on the lower end face of the fixed plate 28. A storage tank 30 is disposed on the upper end face of the top plate 11. A flexible hose 31 connects the storage tank 30 and the grease injection nozzle 29, facilitating the delivery of grease from the storage tank 30 to the bearing via the grease injection nozzle 29. The multi-axis drive assembly includes a slide groove 23 disposed on the upper end face of the top plate 11. A slider 24 is slidably disposed inside the slide groove 23, and a lead screw 26 is rotatably disposed inside the slide groove 23. The lead screw 26 and the slider... 24. A sliding connection is provided. A second motor 27 is provided on one side wall of the top plate 11. The output end of the second motor 27 is fixedly connected to one end of the lead screw 26. The second motor 27 is a common motor and is existing technology. The output end of the second motor 27 drives the lead screw 26 to rotate, thereby driving the slider 24 and the second push cylinder 25 and other components to move horizontally. The lower end face of the slider 24 is provided with the second push cylinder 25. The second push cylinder 25 is a common electric push cylinder or a hydraulic push cylinder and is existing technology. The output end of the second push cylinder 25 drives the fixed plate 28 and the grease injection nozzle 29 and other components to inject bearing grease into the bearing. The output end of the second push cylinder 25 is connected to the fixed plate 28.

[0030] Furthermore, such as Figure 4 As shown, the upper end face of the rotating cone 16 is provided with a first locking groove 17. A locking block 15 is locked inside the first locking groove 17 and connected to the output end of the first motor 14. Grooves 18 are provided on the inner sidewall of the first locking groove 17. An arc-shaped locking spring piece 19 is provided inside each groove 18. The upper end of the arc-shaped locking spring piece 19 is fixedly connected to the inner sidewall of the groove 18. A second locking groove 20 is provided on one side of each arc-shaped locking spring piece 19 on one side wall of the locking block 15. Every two adjacent arc-shaped locking spring pieces 19 and second locking grooves 20 are locked together. The shape of the arc-shaped locking spring piece 19 is as follows: Figure 4 As shown, the upper end of the arc-shaped snap-fit ​​spring piece 19 is fixedly connected to the inner wall of the first snap-fit ​​groove 17. When the snap-fit ​​block 15 is disengaged from the first snap-fit ​​groove 17, the second snap-fit ​​groove 20 will press on the arc-shaped snap-fit ​​spring piece 19, thereby causing the arc-shaped snap-fit ​​spring piece 19 to deform and disengage from the snap-fit ​​limit of the snap-fit ​​block 15. This allows the rotating cone 16 to be easily replaced when pressing down and fixing bearings with large differences in the inner ring size range, thereby further improving the overall adaptability and practicality of the device.

[0031] Furthermore, such as Figure 3As shown, each of the grease injection nozzles 29 has a collection elongated hole 32 on the upper end face of the worktable 10, and each collection elongated hole 32 has a detachable collection frame 33 on the lower end face of the worktable 10. When the device injects grease into the bearing, grease may drip from inside the bearing onto the upper end face of the worktable 10. The collection frame 33 and the collection elongated hole 32 can collect and store the dripping grease, thereby keeping the end face of the worktable 10 clean and avoiding waste of grease.

[0032] First, the bearing is placed on the upper surface of multiple support steps 13 of the same horizontal height with appropriate size, so that the multiple support steps 13 form a support for the outer ring of the bearing. At this time, the multiple support steps 13 do not contact the inner ring of the bearing. Then, the first push cylinder 21 is activated. The first push cylinder 21 drives the rotating cone 16 and other components to move vertically downward until the outer arc surface of the rotating cone 16 contacts the inner ring of the bearing, thus completing the fixing of the bearing.

[0033] Then, the second motor 27 is started. The second motor 27 drives the second push cylinder 25 and the grease injection nozzle 29 and other components to move to the area above the inner and outer rings of the bearing. Then, the second push cylinder 25 is started. The output end of the second push cylinder 25 drives the grease injection nozzle 29 and other components to move to a height suitable for grease injection into the bearing.

[0034] Finally, the grease injection nozzle 29 is activated, and the grease inside the storage tank 30 is delivered to the bearing through the hose 31. During this process, the first motor 14 is activated, and the output end of the first motor 14 drives the rotating cone 16 and other components to rotate, thereby driving the inner ring of the bearing to rotate, which makes the grease injection of the bearing more uniform.

[0035] Example 2:

[0036] Based on Example 1, further examples are made, such as... Figure 5 As shown, each support step 13 has an anti-slip protective pad 34 on its upper surface. The anti-slip protective pad 34 is made of anti-slip material. The anti-slip protective pad 34 increases the friction between the upper surface of the support step 13 and the outer ring of the bearing, thereby improving the stability of the bearing during grease injection.

[0037] Example 3:

[0038] Further embodiments can be made based on Embodiment 1 or 2, such as... Figure 3 As shown, the outer wall of the rotating cone 16 is provided with an anti-slip protective layer 22, which is made of elastic material. By setting the anti-slip protective layer 22, the rotating cone 16 will not damage the bearing inner ring when it comes into contact with the bearing inner ring, thus effectively protecting the bearing inner ring.
