Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to a cleaning device. Background Technology

[0002] A cylinder is formed by the snap-fitting of a cylinder block and a cylinder head, with a cylinder gasket sandwiched between them. The cylinder block typically has multiple mounting holes, such as bolt holes for connecting to the cylinder head. Because these mounting holes are generally deep, metal shavings can easily remain inside during the machining process. Therefore, before assembly, the cylinder block needs to be cleaned of these shavings to prevent them from falling onto the mating surface between the cylinder block and cylinder head due to rotation or vibration during assembly. This ensures that the mating surfaces are not contaminated with metal shavings after assembly, preventing leaks that could cause the cylinder to fail the leak test. This avoids the need for repeated disassembly due to leaks, thus ensuring both good cylinder airtightness and improved assembly efficiency.

[0003] In related technologies, high-pressure cleaners are typically used to flush the mounting holes with water to clean metal shavings. However, this cleaning method is prone to problems where the water mixed with metal shavings does not flow out of the mounting holes, leaving metal shavings behind and preventing complete removal.

This allows impurities within the mounting hole on the material to be loaded to be blown out by the gas, achieving thorough cleaning of the impurities. The cleaning equipment provided in this application utilizes the air jetting device to clean impurities within the mounting hole on the material to be loaded, preventing impurities from remaining in the mounting hole and improving the cleanliness of the impurities within the mounting hole.

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0047] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] Combination Figure 1 and Figure 2As shown in the figure, this application embodiment provides a cleaning device, which includes a fixed bracket 100, a conveying device and an air jet device 300.

[0049] The fixed bracket 100 is mounted on the conveying device. The conveying device is used to convey the material to be loaded, and the surface of the material to be loaded has multiple mounting holes. It should be noted that the material to be loaded can be, for example, a cylinder block of an engine, or other material with mounting holes. The jetting device 300 includes a first telescopic cylinder 301 and multiple jetting elements 302. The first telescopic cylinder 301 is mounted on the fixed bracket 100, and the jetting elements 302 are connected to the telescopic ends of the first telescopic cylinder 301. Each jetting element 302 corresponds to a mounting hole, and the jetting elements 302 are used to eject gas.

[0050] When the conveying device transports the material to be loaded to the target position, the air outlet of the jetting element 302 is aligned with the corresponding mounting hole, and the first telescopic cylinder 301 drives at least a portion of the jetting element 302 to reciprocate within the mounting hole. Since the jetting element 302 can be used for jetting, air can be blown into the mounting hole during the reciprocating movement of the jetting element 302. In this way, impurities in the mounting hole on the material to be loaded can be blown out by the gas to the outside of the material to be loaded, thereby achieving thorough cleaning of the impurities.

[0051] As can be seen from the above, the cleaning equipment provided in this application embodiment uses the jet device 300 to clean metal shavings and other impurities in the mounting holes of the material to be loaded. Since the impurities can be discharged into the mounting holes along with the gas, it can prevent impurities from remaining in the mounting holes, thereby improving the cleaning degree of impurities in the mounting holes and thus improving the sealing performance of the material to be loaded after assembly. At the same time, the cleaning equipment provided in this application embodiment has a relatively simple composition, occupies less space, and has a lower cost.

[0052] The following is in conjunction with the appendix Figures 1 to 5 The various components and functions of the cleaning equipment provided in the embodiments of this application will be described in more detail.

[0053] Combination Figure 1 and Figure 2 As shown, in some embodiments, the first telescopic cylinder 301 includes a first drive member 303 and at least one first telescopic rod 304, the first drive member 303 being used to drive the first telescopic rod 304 to move toward or away from the conveying device.

[0054] The jet device 300 also includes a support member 305 and an air supply member. The support member 305 is connected to the first telescopic rod 304 and has multiple first through holes 307. One end of the jet member 302 is connected to the outlet end of the air supply member, and the other end passes through the corresponding first through hole 307. The jet member 302 extends along a first direction, which is parallel to the axial direction of the mounting hole. It should be noted that the air supply member in this embodiment can be, for example, an air pump. The outlet end of the air supply member is connected to multiple air delivery pipes, each of which is connected to a corresponding jet member 302. Thus, when the air supply member is activated, gas can be delivered into the jet member 302. In this embodiment, the shape of the jet member 302 is adapted to the shape of the mounting hole; for example, it can be a long tube to ensure that impurities deep within the mounting hole can be cleaned. Understandably, when the first telescopic rod 304 moves towards or away from the conveying device, it can drive the carrier 305 to move synchronously. Consequently, the jetting element 302 mounted on the carrier 305 can move synchronously with the carrier 305, allowing it to extend into or exit the corresponding mounting hole. Since the jetting element 302 extends parallel to the axial direction of the mounting hole, it avoids bending or impact deformation with the hole wall, thus improving the reliability of the jetting element 302.

[0055] like Figure 2 As shown, in some embodiments, the jetting device 300 further includes a first sensor assembly 308, which is mounted on the first drive member 303. The first sensor assembly 308 is used to detect the position of the first telescopic rod 304. It should be noted that, based on the detection result of the first sensor assembly 308, the position of the first telescopic rod 304 can be determined, thereby reflecting the position of the jetting member 302 indirectly connected to the first telescopic rod 304. This allows for determination of whether the jetting member 302 has entered or exited the mounting hole. This ensures that the jetting member 302 is fully inserted to thoroughly clean impurities in deeper mounting holes, and also prevents the conveying device from prematurely moving the material to be loaded before the jetting member 302 has exited the mounting hole, thus avoiding damage to the jetting member 302 and improving the reliability of the jetting device 300. In some embodiments, the first sensor assembly 308 includes a first sub-sensor 311 and a second sub-sensor 312, with the first sub-sensor 311 located above the second sub-sensor 312. The first sub-sensor 311 is used to detect that the first telescopic rod 304 has moved to its highest position, and the second sub-sensor 312 is used to detect that the second telescopic rod has moved to its lowest position.

[0056] Combination Figure 1 and Figure 3As shown, in some embodiments, the cleaning device further includes a second telescopic cylinder 211 and at least one limiting component 212, the limiting component 212 being connected to the telescopic end of the second telescopic cylinder 211, the second telescopic cylinder 211 being used to drive at least a portion of the limiting component 212 to rise above the conveying device or to descend below the conveying device.

[0057] When the material to be loaded is at the target position, a portion of the limiting component 212 is positioned above the conveying device and abuts against the front side of the material to be loaded. It should be noted that the front side of the material to be loaded refers to the side of the material to be loaded at the target position that faces forward and has been cleaned. It is understood that the limiting component 212 can initially position the material to be loaded to prevent excessive movement, thereby ensuring that the mounting hole of the material to be loaded is aligned with the jet nozzle 302. In some embodiments, the limiting component 212 includes at least two limiting rods 213 arranged side-by-side.

[0058] like Figure 1 As shown, in some embodiments, the conveying device includes a support base 201, a first support frame 202, a second support frame 203, and multiple roller assemblies 204. The first support frame 202 and the second support frame 203 are respectively mounted on the support base 201 and arranged opposite to each other. The multiple roller assemblies 204 are arranged side by side along the extending direction of the first support frame 202. Each roller assembly 204 includes a fixed shaft 205 and rollers 206. The two ends of the fixed shaft 205 are respectively connected to the first support frame 202 and the second support frame 203, and the rollers 206 are sleeved on the fixed shaft 205. A limiting component 212 is located between two adjacent roller assemblies 204. It should be noted that the multiple roller assemblies 204 are arranged side by side at a preset interval, and the limiting component 212 is located in the gap between two adjacent rollers 206. The material to be loaded is placed on the rollers 206. When the rollers 206 rotate, they can move the material to be loaded, improving the convenience of conveying the material. In some embodiments, the second telescopic cylinder 211 includes a second driving member and a second telescopic rod. One end of the second telescopic rod is connected to a limiting component 212, and the other end of the limiting component 212 is aligned with the gap between two adjacent roller assemblies 204. The second driving member drives the second telescopic rod to move towards or away from the jet device 300. At this time, the limiting component 212 can move synchronously with the second telescopic rod to pass through the gap between the two roller assemblies 204 and above the conveying device. In some embodiments, the limiting component 212 includes a plurality of limiting rods, each corresponding to a second telescopic rod. The end of the limiting rod away from the second telescopic rod bends towards the material to be loaded and abuts against the front side of the material to be loaded.

[0059] like Figure 1As shown, in some embodiments, the fixed bracket 100 includes a fixed frame 101 and four fixed rods 102, wherein two fixed rods 102 are respectively connected to a first support frame 202 and extend perpendicularly to the first support frame 202, and the other two fixed rods 102 are respectively connected to a second support frame 203 and extend perpendicularly to the second support frame 203. The fixed frame 101 is quadrilateral, and the four fixed rods 102 are respectively connected to the four apex corners of the fixed frame 101. A first driving member 303 is mounted on the fixed frame 101, so that the first driving member 303 can drive the first telescopic rod 304 to move towards or away from the conveying device. In some embodiments, the fixed bracket 100 also includes a plurality of protective doors 103, which are respectively located between two adjacent fixed rods 102 and on the fixed frame 101. The protective doors 103 can protect the jetting device 300 and the material to be cleaned. It should be noted that the shape of each protective door 103 can be adjusted according to requirements.

[0060] Combination Figure 1 and Figure 3 As shown, in some embodiments, the conveying device further includes a first limiting bracket 207, a second limiting bracket 208, a first guide member 209, and a second guide member 210. One end of the first limiting bracket 207 is connected to the first support frame 202, and the other end is bent toward the second limiting bracket 208 and connected to the first guide member 209. One end of the second limiting bracket 208 is connected to the second support frame 203, and the other end is bent toward the first limiting bracket 207 and connected to the second guide member 210. Both the first guide member 209 and the second guide member 210 extend along the conveying direction of the material to be loaded, and the first guide member 209 and the second guide member 210 abut against both sides of the material to be loaded. It should be noted that the first guide member 209 and the second guide member 210 can guide the movement of the material to be loaded, thereby ensuring that the material to be loaded can move smoothly in the same direction and avoiding deviation of the material to be loaded. It is understood that the bagged material can have recesses on both sides, and the first guide 209 and the second guide 210 respectively engage with the corresponding recesses to position and guide the material to be packaged. The height of the first guide 209 relative to the first support frame 202 and the height of the second guide 210 relative to the second support frame 203 can be adjusted according to the position of the recesses on the material to be packaged.

[0061] like Figure 3As shown, in some embodiments, the cleaning equipment further includes a second sensor assembly 400 for detecting the position of the material to be loaded. The second sensor assembly 400 includes a first transmitter 401 and a first receiver 402. The first transmitter 401 is mounted on a first limiting bracket 207, and the first receiver 402 is mounted on a second limiting bracket 208. The first transmitter 401 and the first receiver 402 are arranged opposite to each other. It should be noted that the first transmitter 401 is used to emit light, and the first receiver 402 is used to receive light. When the first receiver 402 does not receive light, it indicates that the material to be loaded has entered between the first transmitter 401 and the first receiver 402, that is, the position of the material to be loaded can be detected.

[0062] Combination Figure 1 and Figure 4 As shown, in some embodiments, the cleaning equipment further includes a third telescopic cylinder 500 and at least two positioning shafts 600. The positioning shafts 600 are connected to the telescopic ends of the third telescopic cylinder 500. The third telescopic cylinder 500 is used to drive at least a portion of the positioning shafts 600 to rise above the conveying device or descend below the conveying device. The end face of the positioning shafts 600 has a protrusion 601. The bottom surface of the material to be loaded has a groove corresponding to the protrusion 601. When the material to be loaded moves to the target position, the protrusion 601 engages in the corresponding groove. It should be noted that the limiting component 212 can initially position the material to be loaded, and when the protrusion 601 falls into the groove, it can perform secondary positioning of the material to be loaded. This ensures that the mounting holes on the material to be loaded can be aligned with the jet nozzle 302, ensuring the smooth progress of the cleaning process. It should be noted that the cross-section of the protrusion 601 can be, for example, rhomboid or circular.

[0063] like Figure 4As shown, in some embodiments, the cleaning device includes a first support shaft 700 and a second support shaft 800. The first support shaft 700 and the second support shaft 800 are respectively connected to the telescopic end of a third telescopic cylinder 500. The end faces of the first support shaft 700 and the second support shaft 800 are flush with the end face of a positioning shaft 600. When the material to be loaded moves to the target position, the end faces of the first support shaft 700 and the second support shaft 800 abut against the bottom surface of the material to be loaded. It can be understood that because the end faces of the first support shaft 700 and the second support shaft 800 are flush with the end face of the positioning shaft 600, it ensures that the material to be loaded is in a horizontal state, preventing the material from tilting. It should be noted that the third telescopic cylinder 500 can drive the first support shaft 700, the second support shaft 800 and the positioning shaft 600 to rise or fall synchronously, so that the material to be loaded moves toward or away from the jet device 300, thereby allowing the jet component 302 to move relative to the mounting hole. This not only cleans impurities in deeper positions within the mounting hole, but also improves the cleaning efficiency of impurities.

[0064] like Figure 4 As shown, in some embodiments, the cleaning device further includes a tray 900 with a receiving groove 901. The opening of the receiving groove 901 faces the jet device 300, and the two sides of the bottom of the receiving groove 901 are respectively connected to the positioning shaft 600 and the telescopic end of the third telescopic cylinder 500. It should be noted that the first support shaft 700 and the second support shaft 800 are both located on the same side of the bottom of the receiving groove 901 as the positioning shaft 600 and are connected to the bottom of the receiving groove 901. The receiving groove 901 is located directly below the material to be loaded at the target position, so that impurities blown out from the mounting hole of the material to be loaded can fall into the receiving groove 901, thereby facilitating the collection and processing of impurities. In some embodiments, the third telescopic cylinder 500 includes a third drive member 501 and a third telescopic rod 502. The third drive member 501 drives the third telescopic rod 502 to move toward or away from the jet device 300. The bottom of the receiving groove 901 is connected to the third telescopic rod 502.

[0065] It should be noted that in the embodiments of this application, the first telescopic cylinder 301, the second telescopic cylinder 211, the third telescopic cylinder 500, the first sensor assembly 308, and the second sensor assembly 400 are respectively adapted to be connected to the controller signal. The operating principle of the cleaning device provided in the embodiments of this application will be explained below:

[0066] The controller activates the conveying device, which moves the material to be loaded onto it forward. In response to the second sensor assembly 400 detecting that the material to be loaded has entered between the first transmitter 401 and the first receiver 402, the controller controls the second telescopic cylinder 211 to drive the limiting assembly 212 upwards above the conveying device. After the limiting assembly 212 abuts against the front side of the material to be loaded, the conveying device continues to move the material until the protrusion 601 of the positioning shaft 600 falls into the corresponding groove at the bottom of the material, at which point the material has reached the target position. In response to the material reaching the target position, the controller activates the air supply, controlling the first telescopic cylinder 301 to drive the jet 302 to reciprocate, and controlling the third telescopic cylinder 500 to drive the tray 900 to reciprocate, so that the jet 302 reciprocates within the mounting hole of the material to be loaded. This allows impurities in the mounting hole to be blown out by the gas ejected from the jet 302 to the outside of the material to be loaded and fall into the receiving groove 901 of the tray 900. In response to the jetting time of the jetting component 302 reaching the target duration, the controller controls the first telescopic cylinder 301, the second telescopic cylinder 211, and the third telescopic cylinder 500 to move to their initial positions respectively, and controls the conveying device to continue rolling, so as to transport the cleaned material to be loaded to the next process.

[0067] In summary, the cleaning device provided in this application can thoroughly clean metal shavings and other impurities from the mounting holes of the engine cylinder block, improving the cleanliness of the mounting holes. Therefore, during subsequent assembly, no impurities from the mounting holes will fall onto the mating surfaces of the materials to be installed, such as the mating surface between the cylinder block and the cylinder head. This prevents impurities from causing leaks between the cylinder block and cylinder head, ensuring good cylinder sealing. Furthermore, by avoiding repeated disassembly due to leaks, the assembly efficiency of the production line can be improved.
