Description

Technical Field

[0001] This utility model relates to the field of crankshaft processing equipment technology, specifically to a purging device for an adaptive oil supply crankshaft. Background Technology

[0002] As a core component of an internal combustion engine, the crankshaft typically has a complex internal structure including spiral oil passages, keyways, and oil holes to ensure the delivery of lubricating oil. After finishing, metal shavings, cutting fluid, and grease can easily remain on the crankshaft surface and internal oil passages. Therefore, it requires multiple processes including pre-cleaning, deep cleaning, rinsing, and rust prevention. Among these, after deep cleaning and rinsing but before rust prevention, the outer surface, spiral oil passages, keyways, and oil holes of the crankshaft must be thoroughly dried. Residual moisture significantly reduces the rust prevention effect and can even directly cause crankshaft corrosion, seriously affecting engine reliability and lifespan. Currently, common drying methods such as natural air drying are inefficient, while ordinary air gun cleaning suffers from problems such as arbitrary operation, numerous blind spots, unstable results, and high air consumption. For crankshafts with complex three-dimensional structures, there is a lack of a dedicated device that can adapt to their shape and achieve comprehensive and efficient drying. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a purging device for an adaptive oil supply crankshaft.

A V-shaped structure is formed between the two rollers for positioning and supporting the crankshaft, and the upper part of the rollers is higher than the top of the vertical plate, so that the crankshaft can easily rotate around its axis under the action of external force.

[0007] Preferably, the upright plate and the supporting plate are slidably connected.

[0008] Preferably, the support frame includes a gantry spanning the water collection tank and a connecting assembly; the purging execution module is slidably connected to the top plate of the gantry via the connecting assembly to accommodate crankshafts of different lengths.

[0012] Preferably, there are two sets of the connecting components and the purging execution module, which are symmetrically arranged on the gantry.

[0013] Preferably, a handle is provided at each end of the bearing plate along its length.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by combining the axial reciprocating motion of the moving table with the circumferential rotation of the crankshaft itself, the complex three-dimensional structure such as the outer surface of the crankshaft, the spiral oil groove and the keyway are thoroughly cleaned without dead angles, which significantly improves the uniformity and thoroughness of drying; the support frame allows the nozzle position to be adjusted laterally, and combined with the adjustable spacing of the support components, the device can quickly adapt to crankshafts of different specifications and has strong versatility.

Detailed Implementation

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0018] See Figure 1-4 In one embodiment of this utility model, a purging device for an adaptive oil supply crankshaft is mainly used to efficiently and comprehensively purge and dry the complex structures such as the outer surface, spiral oil groove, keyway and oil hole of the crankshaft after it has been machined and cleaned, so as to ensure the quality of subsequent rust prevention treatment.

[0019] The purging device mainly consists of a base 1, a moving platform 2, a support frame 3, and a purging execution module 4.

[0020] The base 1 includes a water collection tank 11 with an open top for collecting residual moisture carried out by the airflow during the purging process. Two parallel sliding rods 12 are arranged at the bottom inner side of the water collection tank 11. The length direction of the sliding rods 12 is consistent with the length direction of the water collection tank 11, and the sliding rods 12 are fixed to the top of the bottom wall of the water collection tank 11 by a bracket.

[0021] The movable platform 2 is disposed within the water collection tank 11 and can slide along the sliding rods 12. The movable platform 2 includes a rectangular support plate 21, with two linear bearings 22 fixedly installed at the lower end of the support plate 21. These linear bearings 22 cooperate with the two sliding rods 12, allowing the entire movable platform 2 to slide smoothly back and forth along the length of the water collection tank 11. At each end of the support plate 21 along its length, a handle 25 is installed for easy pushing by the operator.

[0022] Furthermore, the upper surface of the movable platform 2 is provided with two sets of opposing crankshaft support assemblies for supporting the main journals of the crankshaft. Each support assembly includes a vertically fixed upright plate 23 and two rollers 24 rotatably mounted on the upper part of the upright plate 23; a V-shaped placement space is formed between the two rollers 24, which facilitates the rapid positioning and stable bearing of the crankshaft. The upper part of the rollers 24 is higher than the top of the upright plate 23, ensuring that the crankshaft only contacts the rollers 24, so that after the crankshaft is placed, it can be easily rotated around its own axis by the operator.

[0023] The support frame 3 includes a gantry frame 31, which is fixedly installed on the water collection tank 11 by bolts and spans across it; a strip-shaped sliding groove 311 is provided on the top plate of the gantry frame 31, and the length direction of the sliding groove 311 is perpendicular to the length direction of the water collection tank 11. The support frame 3 also includes two sets of connecting components, each corresponding to a slider 33, a connecting block 32, and a clamping handle 34. The slider 33 is located on the upper side of the slide groove 311, and the connecting block 32 is located on the lower side of the slide groove 311. The screw of the clamping handle 34 passes through the slider 33 and the slide groove 311 in sequence and is threadedly connected to the connecting block 32. When the clamping handle 34 is tightened, the slider 33 and the connecting block 32 clamp the top plate of the gantry frame 31, thereby achieving fixation. When the clamping handle 34 is loosened, the entire connecting component can drive the purging execution module 4 on it to move laterally along the slide groove 311 to adjust the purging position.

[0024] The purging execution module 4 includes two sets of nozzle assemblies, which are respectively installed on the two sets of connecting assemblies. Each nozzle assembly includes a flat-head fan-shaped air nozzle 41, a connecting pipe 42, and a connector. One end of the connecting pipe 42 is fixed to the connecting block 32 and is used to connect to an external high-pressure air source, while the other end is detachably connected to the nozzle 41 via the connector. The outlet of the nozzle 41 faces the moving stage 2 directly below. Using a flat-head fan-shaped nozzle can generate an air curtain with wide coverage and uniform airflow, thereby improving purging efficiency and uniformity. The working process of this utility model is as follows: First, adjust according to the size of the crankshaft to be treated. Loosen the clamping handle 34, move the nozzle 41 laterally to align it with the part of the crankshaft that needs to be purged, and then tighten it again. If the length of the crankshaft changes, the relative positions of the two sets of crankshaft support assemblies on the bearing plate 21 can be adjusted. Then, the cleaned crankshaft is hoisted onto the V-shaped roller 24 of the moving platform 2, and the external air compressor is started. The high-pressure airflow is ejected from the nozzle 41 through the connecting pipe 42. Next, the operator slowly and steadily pushes the movable platform 2 carrying the crankshaft using handle 25, causing it to reciprocate axially along slide bar 12 below nozzle 41. During this process, the crankshaft can be slowly rotated to ensure that all its circumferential surfaces are fully exposed to the airflow.

[0025] The water blown out is collected in the water collection tank 11. After the entire surface of the crankshaft is completely dried, it can be removed for the next rust prevention process.

[0026] In summary, by combining the axial reciprocating motion of the moving stage with the circumferential rotation of the crankshaft itself, the device achieves thorough cleaning of the complex three-dimensional structures such as the outer surface of the crankshaft, spiral oil grooves, and keyways, significantly improving the uniformity and thoroughness of drying. The support frame allows for lateral adjustment of the nozzle position, and the adjustable spacing of the support components enables the device to quickly adapt to crankshafts of different specifications, making it highly versatile. In one embodiment, the uprights 23 of the two crankshaft support assemblies are preferably slidably connected to the support plate 21. In practice, a guide rail or T-slot along its length can be provided on the upper surface of the support plate 21, and a corresponding slider or locking block can be configured at the bottom of the uprights 23. By releasing the locking mechanism, the uprights 23 and their rollers 24 can be moved along the guide rail, thereby flexibly adjusting the relative distance between the two sets of support assemblies. This design enables the device to stably support and position crankshafts with different journal pitches, significantly improving the versatility and applicability of the equipment.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
