Description

Technical Field

[0001] This utility model mainly relates to the field of steering knuckle cleaning technology, specifically to a deep hole cleaning device for automotive steering knuckles. Background Technology

[0002] The steering knuckle is a key connecting component between the steering system and the suspension system. Its complex structure typically includes deep holes for mounting kingpins, ball joints, or other connecting parts. During the manufacturing and subsequent maintenance of the steering knuckle, impurities such as iron filings, aluminum shavings, grit, oil, and dust inevitably accumulate inside these deep holes.

[0003] Currently, cleaning deep holes in steering knuckles mainly involves using high-pressure water guns or specialized cleaning machines to impact the hole walls with water jets, utilizing the scouring force of the water flow to remove impurities and oil. This method offers relatively good cleaning results and can remove oil. However, a key drawback of existing technologies is that the large amounts of wastewater generated during the cleaning process, containing impurities such as oil, metal shavings, and sand, as well as solid waste washed away by the water flow, are usually directly discharged into the work area or drainage ditches, or simply temporarily collected by operators using containers, lacking effective and systematic collection and filtration methods.

[0028] See attached document Figure 1-4 A deep hole cleaning device for automotive steering knuckles includes a barrel 1 with an open top. A conical guide plate 2 is coaxially arranged inside the barrel 1. The bottom of the conical guide plate 2 is fixed to the bottom wall of the barrel 1 by a plurality of circumferentially evenly distributed support columns 201. A through groove 202 for passing through the steering knuckle spindle is opened at the center of the conical guide plate 2. The steering knuckle spindle passes through the through groove 202 and is limited and fixed by a clamping mechanism 3 provided at the bottom of the conical guide plate 2.

[0029] An annular baffle 4 is fixedly installed on the inner wall of the barrel 1. The annular baffle 4 is located below the conical guide plate 2 and its inner diameter is equal to the outer diameter of the conical guide plate 2. The inner edge of the top of the annular baffle 4 extends upward to form an annular connecting sleeve 401. The annular baffle 4, the annular connecting sleeve 401 and the inner wall of the barrel 1 together form an annular liquid collection tank with a top opening.

[0030] An annular filter basket 5 is detachably installed inside the annular collection tank. Multiple drainage holes 402 are evenly distributed along the circumference on the annular baffle 4. A drainage pipe 6 is connected to the bottom of the tank body 1.

[0031] In this embodiment, after the main shaft of the steering knuckle is inserted into the through groove 202, the main shaft is then fixed by the clamping mechanism 3, thus fixing the steering knuckle inside the barrel 1. Then, the operator uses a high-pressure water gun to clean the deep hole of the steering knuckle. Some of the sewage flushed down by the water gun falls directly into the annular collection tank, some splashes on the inner wall of the barrel 1 and flows into the annular collection tank, and some falls on the conical guide plate 2 and also flows into the annular collection tank. After the sewage enters the annular collection tank, it can be filtered out by the annular filter basket 5. The remaining sewage flows into the bottom of the barrel 1 through the drain hole 402. After enough sewage is collected at the bottom of the barrel 1, the valve installed on the drain pipe 6 can be opened to discharge the collected sewage.

[0032] The clamping mechanism 3 includes mounting plates 301 symmetrically fixed to the bottom of the conical guide plate 2. Cylinders 302 are mounted on the back sides of the two mounting plates 301. The telescopic ends of the cylinders 302 pass through the clearance holes 303 opened in the center of the corresponding mounting plates 301 and are connected to clamping plates 304 with a semi-circular clamping side. The clearance holes 303 are symmetrically provided with through sliding grooves 305 on both sides. A sliding rod 306 is slidably fitted in each sliding groove 305. One end of the sliding rod 306 is fixed to the non-clamping side of the clamping plate 304. A first fitting groove 307 is opened in the clamping side of the clamping plate 304. The clamping mechanism 3 also includes an arc-shaped rubber block 308 that cooperates with the clamping plate 304. One side of the arc-shaped rubber block 308 is provided with a fitting block 309 that can be detachably fitted with the first fitting groove 307, and the other side is provided with a second fitting groove 310.

[0033] In this embodiment, after the controller drives the two cylinders 302 to start simultaneously, and then the sliding rod 306 slides with the corresponding sliding groove 305, the two clamping plates 304 can be driven to clamp and fix the steering shaft main shaft with the arc-shaped rubber block 308 installed on their clamping side. The arc-shaped rubber block 308 is detachably fixed on the clamping plate 304 through the fitting block 309 and the fitting groove 307. The second fitting groove 310 is used to adapt and install another arc-shaped rubber block 308 of a different specification, thereby realizing the step-by-step adaptation of the clamping radius.

[0034] The outer side of the top of the annular filter basket 5 extends outward to form an annular mounting edge 501. The annular mounting edge 501 is fitted with the inner wall of the annular collection tank with a clearance and abuts against the annular support plate 7 fixed to the inner wall of the annular collection tank. The top of the annular mounting edge 501 is symmetrically provided with two handles 503, and the bottom is fixed with multiple positioning rods 502 evenly distributed along the circumference. The annular support plate 7 is provided with positioning holes 701 that correspond one-to-one with the positioning rods 502 and can be inserted and matched. The bottom of the annular mounting edge 501 is also fixed with a first magnetic suction member 8, and the top of the annular support plate 7 is fixed with a second magnetic suction member 9 that attracts the first magnetic suction member 8.

[0035] In this embodiment, after the annular mounting edge 501 abuts against the annular support plate 7, since the annular mounting edge 501 is in clearance fit with the inner wall of the annular collection tank, the operator can use the handle 503 to drive the annular mounting edge 501 to rotate in the annular collection tank until each positioning rod 502 is inserted into the corresponding positioning hole 701. Then, with the magnetic force of the first magnetic suction member 8 and the second magnetic suction member 9, the installation of the annular filter basket 5 can be completed. Similarly, the operator can use the handle 503 to pull the annular mounting edge 501 outward to remove the annular filter basket 5 from the annular collection tank.

[0036] Finally, it should be noted that barrel 1 is made of transparent material so that staff can observe its interior at any time.

However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0038] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
