Description

Technical Field

[0001] The invention relates to the technical field of disc parts post-processing, in particular to a brake disc oil-immersion drying machine. Background Art

[0002] In the manufacturing of automotive parts, especially disc-type parts, a cleaning process and a rust prevention process are required after machining is completed and before product packaging. The cleaning process is a water wash. After the cleaning process, the surface of the workpiece is first hung with water to dry, and then immersed in an oil tank for rust prevention. The amount of rust prevention oil on the surface of the workpiece cannot be too much, otherwise the rust prevention oil will soak into the paper box after packaging, causing damage to the paper box. In the current cleaning line, there is a need for turnover between the cleaning process and the rust prevention process. The workpieces that have completed the cleaning process are first stacked, and then each workpiece is manually hung on the cleaning line. After a long cycle, it enters the rust prevention oil tank. After another long cycle, the surface rust prevention oil is air-dried before it is taken off the line for packaging. This operation process has a long cycle, occupies a large area, and is costly. In addition, the rust prevention oil on the product surface will naturally drip, which not only wastes the rust prevention oil, but also makes the amount of attached oil uncontrollable, creating the risk of the packaging paper box being soaked with rust prevention oil.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] See also Figure 1-Figure 2This embodiment discloses a brake disc oil immersion and drying machine, including a frame 1 and an oil immersion mechanism 2 and a drying mechanism 3 connected by the frame 1. The frame 1 is formed by welding square tubes and steel plates. The oil immersion mechanism 2 and the drying mechanism 3 are distributed side by side along the length direction of the frame 1.

[0025] Specifically, the oil immersion mechanism 2 includes an oil immersion tank 21 fixedly connected to the frame 1. A liftable workpiece placement plate 22 is located within the oil immersion tank 21. This plate is used to position and position workpieces to be oiled. In this embodiment, the plate 22 is rotatable. When tilted, it allows excess oil on the workpiece and on the top surface of the plate 22 to flow back into the oil immersion tank 21, preventing oil from dripping and wasting during workpiece transfer.

[0026] In this embodiment, the workpiece placement plate 22 is constructed as a rectangular plate structure, and a V-shaped baffle 221 is fixed on its top surface for isolating the brake disc workpiece, and a through hole is provided on the V-shaped baffle 221 for reflux of the anti-rust oil.

[0027] like Figure 4 As shown, the oil immersion mechanism 2 also includes a lifting mechanism connected to the workpiece placement plate 22. The lifting mechanism includes two sets of lifting cylinders 23 fixedly connected to the outer walls on both sides of the oil immersion box 21 and a lifting bracket 24 fixedly connected to the output end of the lifting cylinder 23. The bottom end of the lifting bracket 24 extends into the oil immersion box 21 and is respectively connected to both sides of the workpiece placement plate 22. Starting the lifting cylinder 23 can drive the workpiece placement plate 22 to rise and fall, so that it can be immersed in or separated from the rust-proof oil.

[0028] Further, see Figure 3 and Figure 4 In this embodiment, the lifting bracket 24 is fixedly connected to a rotating shaft 25 at one end corresponding to the workpiece placement plate 22. The rotating shaft 25 passes through the side wall of the workpiece placement plate 22 and is rotatably connected thereto, thereby making the workpiece placement plate 22 rotatable.

[0029] To ensure the balance and stability of the workpiece placement plate 22 when not unloading oil, in this embodiment, the oil immersion mechanism 2 further includes a balancing spring 262 disposed on the bottom side of the workpiece placement plate 22. Specifically, a spring holder 261 is fixedly connected to the bottom of the jacking bracket 24. The spring holder 261 includes a first connecting end arranged vertically and a second connecting end arranged horizontally. The first connecting end extends toward the bottom of the oil immersion tank 21, and its length roughly matches the length of the balancing spring 262. The second connecting end is fixed to the bottom of the first connecting end and is constructed in an L-shaped structure. It extends to a position corresponding to the bottom of the workpiece placement plate 22. The balancing spring 262 is fixedly connected between the second connecting end of the spring holder 261 and the bottom of the workpiece placement plate 22. The balancing spring 262 not only ensures the balance of the workpiece placement plate 22 in the absence of external forces, but also provides a buffering force when the workpiece placement plate 22 tilts, preventing the workpiece placement plate 22 from rotating excessively and causing the workpiece to fall into the oil immersion tank 21.

[0030] In order to provide the workpiece placement plate 22 with a rotational driving force, in this embodiment, the oil immersion mechanism 2 further includes a first driving member for driving the workpiece placement plate 22 to rotate, such as Figure 1 and Figure 2 As shown, the first driving member includes a push cylinder 271 fixedly connected to an upper position within the oil immersion tank 21, and a wedge-shaped push block 272 fixedly connected to the output end of the push cylinder 271. The push cylinder 271 is fixedly connected to the interior of the oil immersion tank 21 via a cylinder mounting plate 33. In this embodiment, the top surface of the wedge-shaped push block 272, i.e., the push surface, is configured as an inclined surface, which, when pushed by the push block, can tilt the workpiece placement plate 22 to a certain angle.

[0031] Better, combined Figure 6 In this embodiment, an oil pump 28 is fixedly connected to the top of the oil immersion tank 21 and secured via an oil pump mounting bracket. The oil pump 28 is used to extract and replace the rust-proof oil within the oil immersion tank 21. An oil residue cleaning port 29 is also provided at the bottom of the oil immersion tank 21. The bottom plate of the oil immersion tank 21 is configured to be inclined toward the oil residue cleaning port 29, allowing waste oil residue to be discharged through the oil residue cleaning port 29.

[0032] See also Figure 5 and Figure 6The drying mechanism 3 includes a guide plate 31 fixedly connected to the frame 1, an enclosure housing roughly covering the guide plate 31, and a clamping member 32 connected via the guide plate 31. In this embodiment, the enclosure housing encloses a working chamber, the guide plate 31 is tilted, and its lower end is connected to the interior of the oil immersion tank 21; the clamping member 32 can adopt a clamping structure in the prior art, for example, a three-jaw chuck, and the clamping member 32 is used to clamp the workpiece, and the clamping member 32 is rotatable. The rotation achieves the effect of drying the workpiece, and the discharged oil flows back into the oil immersion tank 21 through the guide plate 31.

[0033] In this embodiment, the structure of the drying mechanism 3 is described in detail by taking a three-jaw chuck as an example.

[0034] In this embodiment, the structure of the three-jaw chuck adopts the existing technology, which is provided with three groups of jaws that can move radially. The three groups of jaws apply clamping force to the brake disc workpiece, and the movement of the three groups of jaws is driven by a second driving member fixedly connected to the frame 1. More specifically, the frame 1 is fixed with a mounting plate 33 below the guide plate 31, and the second driving member includes a tensioning cylinder 34 fixedly connected to the bottom end of the mounting plate 33 through a mounting seat, and the piston rod end of the tensioning cylinder 34 faces the three-jaw chuck and is fixedly connected to the center shaft 35, and the top end of the center shaft 35 is sleeved with a rack shaft 36. Correspondingly, the second driving member further includes a plurality of groups of mutually meshing gears 37 rotatably connected to the chuck seat 322 of the three-jaw chuck, and the gear 37 is vertically arranged, and the gear 37 close to the rack shaft 36 is meshed with the rack shaft 36, and the plurality of groups of gears 37 are all meshed with a long rack 38 fixedly connected to the bottom of the claw seat 321. Then, the tensioning cylinder 34 provides an axial force, and the axial force can be converted into a radial clamping force through the cooperation of the rack shaft 36, the gear 37 and the long rack 38. In order to ensure the linear motion stability of the clamping claws when they move toward the center, each chuck seat 322 is respectively installed with two sets of linear guide rails 39, and the clamping claw seat 321 slides with the guide rails through a slider.

[0035] Furthermore, the drying mechanism 3 also includes a third driving member for driving the three-jaw chuck to rotate. Specifically, the third driving member includes a rotatable rotating spindle 40 sleeved on the outside of the central shaft 35. The rotating spindle 40 is rotatably connected to the guide plate 31 and the mounting plate 33 through bearing seats. The top of the rotating spindle 40 is fixedly provided with a connecting seat, which is fixedly connected to the bottom end of the chuck seat 322. The three-jaw chuck is driven to rotate synchronously by the rotation of the rotating spindle 40. It should be noted that the rotating spindle 40 and the central shaft 35 are clearance-fitted, and the central shaft 35 does not rotate with the rotating spindle 40. The third driving member further includes a synchronous pulley 41 fixedly sleeved on the rotating spindle 40, and the synchronous pulley 41 is driven to rotate by a drive motor 42 fixedly connected to the side end of the frame 1.

[0036] It can be understood that the drying mechanism 3 in this embodiment can be used not only in the rust-proof drying process of the workpiece, but also in drying the moisture on the surface of the workpiece after the cleaning process.

[0037] In actual application, the robot gripper or truss manipulator grabs the workpiece that needs to be rust-proofed and places it on the workpiece placement plate 22. At this time, the lifting cylinder 23 retracts, pulling the lifting bracket 24 down to the bottom of the oil immersion box 21 to immerse in oil. Then the lifting cylinder 23 is pushed out, bringing the workpiece out of the oil surface and lifting it to the position corresponding to the wedge-shaped push block 272. At this time, the pushing cylinder 271 is activated, causing the wedge-shaped push block 272 to push the workpiece placement plate 22. Under the action of the rotating shaft 25, the workpiece placement plate 22 is inclined at a certain angle, and the excess anti-rust oil flows back into the oil immersion box 21 through the through hole on the baffle 221. At this time, under the action of the balance spring 262, the workpiece placement plate 22 will not flip over and cause the workpiece to fall into the oil immersion box 21. After the oil control is completed, the pushing cylinder 271 is retracted. At this time, the workpiece placement plate 22 is restored to a horizontal state under the action of the balance spring 262.

[0038] After the oil immersion is complete, the workpiece is grabbed onto the three-jaw chuck of the drying mechanism 3. The tensioning cylinder 34 retracts, pulling the center shaft 35 and rack shaft 36 downward. The three sets of jaws now move radially and clamp the workpiece. After the workpiece is clamped, the drive motor 42 is activated, driving the synchronous pulley 41 to rotate, which in turn drives the rotating spindle 40 and the chuck seat 322 to rotate synchronously to dry the workpiece. The rust-proof oil removed from the workpiece flows back into the oil immersion housing 21 via the guide plate 31. The drive motor 42 can also be set to a rotation speed and drying time to control the amount of rust-proof oil remaining on the workpiece surface. After the drying operation is complete, the workpiece is taken to the packaging process. When the rust-proof oil in the oil tank needs to be replaced after a period of use, the oil pump 28 is activated to extract the rust-proof oil from the tank. The remaining oil residue is cleaned through the oil residue cleaning port 29, and then new rust-proof oil is replenished.

[0039] The brake disc oil immersion and drying machine provided in this embodiment integrates oil immersion and drying. On the one hand, it can replace the traditional large-scale cleaning line to realize oil immersion and drying related operations, and can quickly dry the excess anti-rust oil on the workpiece surface without the need for long-distance circulation, effectively shortening the anti-rust process cycle, and the drying mechanism can control the amount of oil on the workpiece surface by setting the drying time and speed; on the other hand, the excess oil generated during the oil immersion and drying process can be recycled and refluxed, thereby achieving the effect of improving oil utilization and reducing oil waste.
