Description

Technical Field

[0001] This utility model relates to the technical field of water jet cleaning devices, specifically a water jet cleaning device for cleaning cylinders. Background Technology

[0002] As a core component of the engine, the cylinder block has a complex external geometry, featuring heat sinks, bolt holes, mounting surfaces, and various uneven structures. During manufacturing, assembly, or repair, stubborn contaminants such as oil, grease, dust, and anti-corrosion coatings easily adhere to the cylinder block surface. If these contaminants are not thoroughly cleaned, they will not only affect the engine's cooling efficiency and hinder subsequent testing and assembly processes, but may also lead to component corrosion or impurities penetrating the interior, posing a serious threat to the overall quality and reliability of the engine. Therefore, achieving thorough and efficient cleaning of the complex external surfaces of the cylinder block, especially various crevices and uneven areas, has always been a key process in the manufacturing and repair industries.

[0003] Currently, high-pressure water jet technology has become one of the mainstream methods for cleaning the exterior of cylinder blocks due to its environmentally friendly and efficient characteristics. However, traditional fixed or simple reciprocating nozzles have significant limitations. Their spray trajectory is singular and the coverage angle is fixed, making it difficult to effectively adapt to the complex geometric contours of the cylinder block exterior. This results in the cleaning jet not accurately covering all surfaces, especially in areas such as gaps between heat sinks and irregular joint surfaces, easily forming "cleaning blind spots." To ensure cleanliness, repeated cleaning or extended cleaning time is often required, leading to low cleaning efficiency, high water and energy consumption, and becoming a bottleneck for improving overall process efficiency. Therefore, a water jet cleaning device for cylinder block cleaning is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water jet cleaning device for engine block cleaning, which has the advantages of being able to perform multi-angle cleaning of the exterior of the engine block, thus solving the problem of inadequate cleaning in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water jet cleaning device for cleaning cylinders, comprising a support frame 1, characterized in that: a water pipe 4 for connection is provided on the support frame 1, a cleaning mechanism 3 for multi-angle cleaning of the cylinder is provided at the bottom of the water pipe 4, and a transmission component 2 for transmission is provided on one side of the support frame 1, the transmission component 2 being tractively connected to the water pipe 4. The transmission assembly 2 includes a mounting base 21 fixedly mounted on the support frame 1. A transmission motor 22 is mounted on the mounting base 21. A transmission gear 23 is mounted at the output end of the transmission motor 22. A transmission chain 24 is driven by the transmission gear 23. A driven gear 25 is driven by the transmission chain 24. The driven gear 25 is driven by the water pipe 4.

[0006] Furthermore, the support frame 1 includes two mounting plates 11, which are arranged vertically at intervals. Multiple support columns 12 are provided in the middle to support and form an installation space for the installation of the drive motor 22.

[0007] Furthermore, both of the aforementioned mounting plates 11 are provided with connecting bearings 13, and are rotatably connected to the water pipe 4 through the connecting bearings 13.

[0008] Furthermore, the cleaning mechanism 3 includes a connecting pipe 31 that is connected to the water pipe 4, and the connecting pipe 31 is connected to a diversion pipe 32; The diversion pipe 32 includes a straight pipe connected to the connecting pipe 31, and two branch pipes are provided at both ends of the straight pipe, with the two branch pipes being perpendicularly connected to the straight pipe.

[0009] Furthermore, the straight pipe is provided with a first cleaning nozzle 33 for cleaning the top of the workpiece, one of the branch pipes is provided with a second cleaning nozzle 34, and the other branch pipe is provided with a cleaning brush 36 for cleaning the side of the workpiece.

[0010] Furthermore, the cleaning brush 36 is connected to the branch pipe via a connector 35. The connector 35 includes a slide tube and a sleeve and can achieve a sealed sliding connection. The sleeve is provided with a limiting ring for limiting the slide tube.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This water jet cleaning device for engine cylinder cleaning precisely drives the water pipe and cleaning mechanism to rotate 360 ​​degrees or swing at a specific angle through a transmission assembly consisting of a drive motor, drive gears, a drive chain, and a driven gear. It successfully converts the rotational motion of the motor into the revolution of the cleaning mechanism around the workpiece, thus achieving comprehensive, multi-angle, high-pressure water jet coverage of the top and sides of the engine cylinder block without blind spots. This fundamentally overcomes the "cleaning shadows" and blind spots inherent in traditional fixed or simple reciprocating nozzles, significantly improving cleaning efficiency and coverage uniformity.

[0012] II. This water jet cleaning device for cylinder cleaning employs a combined cleaning mode that integrates high-pressure water jet and mechanical brushing. The cleaning mechanism's branch pipe design not only includes first and second cleaning nozzles for rinsing the top and sides, but also a cleaning brush with an elastic clamping structure on one side branch pipe. Under spring action, this cleaning brush adaptively adheres to the complex sides of the cylinder, powerfully scraping and scrubbing stubborn dirt during its revolution. This synergistic effect with the high-pressure water jet is highly efficient, particularly effective at removing thick oil stains and adhesive impurities, achieving a deep cleaning through integrated rinsing and scrubbing. The cleaning effect and overall efficiency far surpass those of a single water jet cleaning method. Attached Figure Description

[0015] 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.

[0016] See appendix Figure 1 To be continued Figure 3 The present invention provides a water jet cleaning device for cleaning cylinders.

[0017] As attached Figure 1 As shown, the device mainly includes a support frame 1, a transmission assembly 2, and a cleaning mechanism 3. The support frame 1 serves as the basic framework of the entire device and includes two mounting plates 11 spaced apart vertically. The two mounting plates 11 are fixedly connected by multiple support columns 12, thus forming a stable installation space. Connecting bearings 13 are installed on both the upper and lower mounting plates 11.

[0018] A water pipe 4 passes through the connecting bearing 13 on the upper and lower mounting plates 11 and is interference-fitted with the inner ring of the connecting bearing 13, thereby enabling the water pipe 4 to rotate flexibly relative to the support frame 1. The top end of the water pipe 4 is used to connect to the water supply pipeline of an external high-pressure water pump through a rotary joint to ensure that high-pressure water can be continuously and leak-free during the rotation of the water pipe 4.

[0019] The transmission assembly 2 is used to drive the water pipe 4 to rotate. The transmission assembly 2 includes a mounting base 21 that is bolted to the lower mounting plate 11. A drive motor 22 is mounted on the mounting base 21. The drive motor 22 is preferably a servo motor or a stepper motor to facilitate precise control of the rotation angle. A drive gear 23 is mounted on the output shaft of the drive motor 22. A drive chain 24 meshes with the drive gear 23, which allows the drive motor 22 to drive the drive chain 24 to rotate a driven gear 25. The driven gear 25 is fixedly mounted on the water pipe 4 by means of a key connection or other means.

[0020] When the drive motor 22 starts, it drives the drive gear 23 to rotate, which in turn drives the drive chain 24 meshing with it to rotate, thereby driving the driven gear 25 meshing with the drive chain 24 to rotate, ultimately causing the water pipe 4 to rotate or swing precisely 360 degrees around its axis. This gear-rack transmission method converts the rotational motion of the motor into the linear motion of the rack, and then into the rotational motion of the driven gear. Its transmission principle and connection relationship can be specifically implemented by those skilled in the art based on this description.

[0021] As attached Figure 2 As shown, the cleaning mechanism 3 is located at the bottom of the water pipe 4 and is used to clean the engine block located below it from multiple angles. The cleaning mechanism 3 includes a connecting pipe 31 that communicates with the lower end of the water pipe 4. The lower end of the connecting pipe 31 is connected to a branch pipe 32. The branch pipe 32 consists of a horizontally arranged straight pipe and two branch pipes that are vertically connected to both ends of the straight pipe, forming an approximately "I"-shaped structure.

[0022] The connection between the connecting pipe 31 and the branch pipe 32, as well as the connection between the straight pipe of the branch pipe 32 and the two branch pipes, are fixedly connected and the internal flow channels are sealed and connected by welding or threaded sealing to ensure the smooth passage of high-pressure water.

[0023] A first cleaning nozzle 33 is located at the center of the bottom of the straight pipe of the branch pipe 32. This nozzle points vertically downward and is used to directly rinse the top surface of the cylinder. A second cleaning nozzle 34 is located at the end of one branch pipe. This nozzle is angled downward and is used to clean one side of the cylinder. A cleaning brush 36 is installed at the end of the other branch pipe via a connector 35.

[0024] The connector 35 includes a sleeve 351 fixedly connected and communicating with the end of the branch pipe, and a slide tube slidably inserted into the sleeve, with the cleaning brush 36 installed at its outer end. A compression spring (not shown in the figure) is provided between the inner end of the slide tube and the bottom of the sleeve, and the cleaning brush 36 is installed at the outer end. The end of the sleeve is tapered and has a limiting ring threadedly connected to the opening of the sleeve. When the limiting ring rotates, it can cause the end of the sleeve to retract, thereby preventing the slide tube from coming out and achieving a seal. The bristles of the cleaning brush 36 are made of wear-resistant material (such as nylon or steel wire).

[0025] Its working principle and beneficial effects are as follows: High-pressure water enters through the water pipe 4, flows into the diversion pipe 32 through the connecting pipe 31, and finally sprays out from the first cleaning nozzle 33 and the second cleaning nozzle 34, forming a high-pressure water jet. Simultaneously, driven by the transmission component 2, the entire cleaning mechanism 3 can drive the nozzles and cleaning brush 36 to revolve around the cylinder. Under the action of the compression spring, the cleaning brush 36 always maintains a certain pressure against the other side of the cylinder, achieving mechanical brushing during its revolution. This, combined with the high-pressure water jet, achieves a synergistic cleaning mode of "high-pressure water rinsing + mechanical brushing," which is particularly effective at removing firmly attached oil and impurities. By controlling the rotation of the transmission motor 22, the cleaning mechanism 3 can be made to swing at a specific angle or rotate continuously, thereby achieving flexible multi-angle cleaning without dead angles.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
