Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a flanging device for bearing processing. Background Technology

[0002] The bearing shell is a key component of a sliding bearing. It directly wraps around the journal and forms a friction pair through an oil film. It bears rotational loads and reduces wear. Flanged bearing shells have flanges extending from the edge of the shell, which cooperate with the bearing housing or retaining ring to form an axial limiting structure. For example, engine crankshafts usually have only one flanged bearing shell to ensure the uniqueness of the axial positioning of the entire shaft.

[0003] Traditionally, when processing bearing flanges, a progressively moving and rotating protrusion is used to press against the edge of the bearing flange, thereby achieving flange formation during the upward movement. However, this flange formation operation is time-consuming, requires the protrusion to advance layer by layer, is inefficient, delays the work progress, and is not conducive to efficient flange formation in bearing flange processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flanging device for bearing processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flanging device for bearing processing, comprising a mounting frame, wherein an electric cylinder one is fixedly mounted on the lower surface of the mounting frame, an electric cylinder two is fixedly mounted on the upper surface of the mounting frame, and a flanging assembly is provided in the middle of the mounting frame;

[0006] The flange assembly includes a fixing frame, which is fixedly connected to the middle of the mounting frame. A supporting round block is fixedly connected to the middle of the fixing frame. An upper push frame is fixedly connected to the output end of the electric cylinder. Two upper push plates are fixedly connected to the upper surface of the upper push frame. An inner groove is opened inside the upper push plate.

[0007] As a further description of the above technical solution:

[0008] Two resistance wires are installed inside the inner groove, and the inner groove is filled with thermally conductive adhesive.

[0009] As a further description of the above technical solution:

[0010] The output end of the electric cylinder is fixedly connected to a lower pressure shell, and positioning shells are fixedly connected to both sides of the lower pressure shell.

[0011] As a further description of the above technical solution:

[0012] The support block is provided with a limiting component on its outside. The limiting component includes two limiting plates, which are disposed on the outside of the support block. An arc-shaped rod is fixedly connected to one side of each limiting plate.

[0013] As a further description of the above technical solution:

[0014] One of the limiting plates has a long rod fixedly connected to one side, and the other limiting plate has a short rod fixedly connected to one side. A toothed rod is fixedly connected to one end of both the long rod and the short rod.

[0015] As a further description of the above technical solution:

[0016] A limiting sleeve is fixedly connected to one side of the limiting plate, a limiting rod is fixedly connected to one side of the mounting frame, two limiting sleeves are slidably connected to the outside of the limiting rod, and a support plate is fixedly connected to one side of the fixing frame.

[0017] As a further description of the above technical solution:

[0018] A stepper motor is fixedly installed on the lower surface of the support plate. A gear is fixedly connected to the output end of the stepper motor. The gear is meshed with two racks. The stepper motor is fixedly installed on one side of the fixed frame.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the flanging assembly, utilizes the supporting round block to facilitate the support of the bottom of the bearing bush, while the downward pressing of the lower shell facilitates the limiting and clamping of the top of the bearing bush. The heating of the limiting plate by the resistance wire causes the edge of the limiting plate to heat up, and under the upward action of the limiting plate, it is easy to quickly lift the edge of the bearing bush and thus flanging. The heated limiting plate helps to improve the plasticity of the edge of the bearing bush and reduce the damage and cracking of the bearing bush edge during flanging.

[0021] 2. By setting up a limiting component, this utility model facilitates the positioning of the two sides of the bearing placed on the support block by using the limiting plates on both sides and the arc-shaped rods that cooperate with them before the bearing is flanged. This corrects the bearing and reduces the phenomenon of misalignment and failure of flangeing caused by the bearing being skewed or slipping. Attached Figure Description

[0032] 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 protection scope of the present utility model.

[0033] As attached Figure 1-5 As shown, one embodiment of this utility model is provided: a flanging device for bearing processing, including a mounting frame 1, an electric cylinder 2 fixedly mounted on the lower surface of the mounting frame 1, an electric cylinder 3 fixedly mounted on the upper surface of the mounting frame 1, and a flanging assembly provided in the middle of the mounting frame 1.

[0034] The flange assembly includes a fixing frame 4, which is fixedly connected to the middle of the mounting frame 1. A support block 5 is fixedly connected to the middle of the fixing frame 4 to facilitate support for the bearing. An upper push frame 6, which is U-shaped, is fixedly connected to the output end of the electric cylinder 2 to drive the upper push plate 7 to move upward. Two upper push plates 7 are fixedly connected to the upper surface of the upper push frame 6. The upper push plate 7 is circular and its circular area is larger than that of the support block 5. The upper surface of the upper push plate 7 is in contact with the inner wall of the positioning shell 11. An inner groove 8 is opened inside the upper push plate 7 and is arc-shaped.

[0035] As attached Figure 5 As shown, two resistance wires 9 are installed inside the inner groove 8, and the inner groove 8 is filled with thermally conductive adhesive to facilitate the generation of heat and transfer the heat to the upper push plate 7.

[0036] As attached Figure 8 As shown, the output end of the electric cylinder 2 3 is fixedly connected to the lower pressure shell 10, which presses and limits the upper surface of the bearing. Both sides of the lower pressure shell 10 are fixedly connected to the positioning shell 11, which facilitates limiting the rising position of the upper push plate 7. The inner wall space of the positioning shell 11 helps the bearing edge to fit when it is turned over.

[0037] As attached Figure 6 As shown, a limiting component is provided on the outside of the supporting circular block 5. The limiting component includes two limiting plates 12. The two limiting plates 12 are located on the outside of the supporting circular block 5, on both sides of the supporting circular block 5. An arc-shaped rod 13 is fixedly connected to one side of the limiting plate 12 to facilitate the limiting of the bearing edge. A long rod 14 is fixedly connected to one side of one of the limiting plates 12 to facilitate the movement of one of the limiting plates 12 when the long rod 14 moves.

[0038] As attached Figure 7 As shown, a short rod 15 is fixedly connected to one side of another limiting plate 12, so that the short rod 15 can drive the other limiting plate 12 to move when it moves. A toothed rod 16 is fixedly connected to one end of both the long rod 14 and the short rod 15. The toothed rod 16 is a square rod with multiple toothed grooves on one side, so that the toothed rod 16 can drive the limiting plate 12 to move through its respective long rod 14 and short rod 15 when it moves. A limiting sleeve 17 is fixedly connected to one side of the limiting plate 12.

[0039] As attached Figure 1 As shown, a limiting rod 18 is fixedly connected to one side of the mounting frame 1, and two limiting sleeves 17 are slidably connected to the outside of the limiting rod 18. The limiting rod 18 plays a limiting role on the limiting sleeves 17.

[0040] As attached Figure 3As shown, a support plate 19 is fixedly connected to one side of the fixed frame 4, which supports the two racks 16. A stepper motor 20 is fixedly installed on the lower surface of the support plate 19. A gear 21 is fixedly connected to the output end of the stepper motor 20. The gear 21 is meshed with the two racks 16. The edge gear 21 drives the two racks 16 to move relative to each other. The stepper motor 20 is fixedly installed on one side of the fixed frame 4.

[0041] Working principle: In use, first place the bearing bush, whose width is slightly larger than that of the support block 5, on the support block 5. At this time, the two sides of the bearing bush to be turned extend out of the two sides of the support block 5, and the upper push plate 7 is below the two sides of the bearing bush. Then, use the external controller to start the stepper motor 20. When its output end drives the gear 21 to rotate, the gear 21 will drive the two gear rods 16 to move relative to each other under the action of adhering to the two gear rods 16. When the gear rods 16 slide on the upper surface of the support plate 19, one of them will pull one of the limiting plates 12 to move through the short rod 15, and the other gear rod 16 will pull the other limiting plate 12 to move through the long rod 14, so that the two limiting plates 12 move relative to each other. Thus, when the arc rod 13 moves, the arc rods 13 on both sides move closer to the edge of the bearing bush, limiting the two sides of the placed bearing bush. Start the electric cylinder 3, and when its output end drives the lower pressure shell 10 and the positioning shell 11 to press down, the lower pressure shell 10 and the positioning shell 11 are pressed down. The shell 10 presses against the upper surface of the bearing, thus limiting and fixing the bearing. After the bearing is fixed, the reverse function of the stepper motor 20 is activated, indirectly causing the two limiting plates 12 to move away from each other, releasing the clamping and limiting on both sides of the bearing. Then, the resistance wire 9 is turned on, causing it to heat up and transfer the heat to the upper push plate 7, causing the edge of the upper push plate 7 to heat up. Then, the starting electric cylinder 2 is controlled, causing its output to drive the upper push frame 6 to move upward. When the upper push frame 6 moves upward, it will drive the upper push plates 7 on both sides to move upward, causing the upper push plates 7 to push the edges of the extended support block 5 upward. When the edge comes into contact with the heated upper push plate 7, its plasticity will increase. Under the action of continuous heating and being pushed upward by the upper push plate 7, the edge of the bearing will be squeezed into the interior of the positioning shell 11, and the upper surface of the upper push plate 7 will fit against the inner wall of the positioning shell 11, thus causing the bearing to be flipped. When removing it, the upper push plate 7 and the lower pressing shell 10 are reset so that the operator can remove the bearing.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
