During the cleaning process, the elastic force of the spring and the pressure of the gas in the trachea will first drive the push rod downward. At this time, due to the high pressure state still existing in the inner cavity of the trachea, the moving rod will not move upward, thereby achieving the purpose of fixing the position of the casting during the cleaning process, avoiding the situation where the casting is moved by the impact of high-pressure water, resulting in failure to clean smoothly, and improving the cleaning effect.

Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, and more particularly to a cleaning device for casting processing. Background Art

[0002] During the casting process, molding sand is used as the molding mold. After demolding, some molding sand and other impurities will adhere to the casting. Therefore, a cleaning device is needed to clean the molding sand and other impurities.

[0003] A Chinese invention patent with publication number CN104923531B discloses a tunnel-type cleaning machine, which includes a conveyor line. An immersion chamber, a rinse chamber, and a cleaning chamber are sequentially arranged along the conveying direction of the conveyor line. Isolation curtains are provided at the channel entrance and exit, as well as between the immersion chamber and the rinse chamber, and between the rinse chamber and the cleaning chamber. The isolation curtains can block the passage of water mist and reduce cross-contamination. The immersion chamber, the rinse chamber, and the cleaning chamber are all equipped with water tanks, and the three water tanks are separated from each other by partitions. A water tank is provided below each of the immersion chambers, the rinse chamber, and the cleaning chamber, namely, an immersion water tank, a rinse water tank, and a cleaning water tank. The pipelines of the immersion chamber, the rinse chamber, and the cleaning chamber, as well as the connections between the pipelines and the water tanks and the spraying device, are connected via clamps.

[0026] 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.

[0027] Example 1:

[0028] like Figures 1 to 5 As shown, the present invention provides a cleaning device for processing a casting 99, comprising a housing 1, an inner cavity of the housing 1 being transmission-connected to a conveying assembly 2, a rear end of the inner cavity of the housing 1 being provided with a driving assembly 3, and a middle portion of the inner cavity of the housing 1 being provided with a positioning assembly 4;

[0029] The conveying assembly 2 includes a toothed chain 24, which is located at the rear end of the inner cavity of the shell 1. The conveying assembly 2 also includes a motor 21, which is fixedly mounted at the front end of the shell 1. The inner cavity of the shell 1 is rotatably connected to a transmission sprocket 22, and the motor 21 is in transmission connection with the transmission sprocket 22. The surface of the transmission sprocket 22 is in transmission connection with a metal conveying mesh chain 23. The toothed chain 24 is fixedly mounted at the rear end of the metal conveying mesh chain 23. A support roller 25 is rotatably connected to the middle part of the inner cavity of the shell 1, and the support roller 25 is in contact with the metal conveying mesh chain 23.

[0030] The driving assembly 3 includes a gear 1 31, which is rotatably connected to the rear end of the inner cavity of the housing 1. The end of the gear 1 31 close to the positioning assembly 4 is meshed with a rack 1 32. A push rod 33 is fixedly installed on the top of the gear 1 31. The driving assembly 3 also includes a positioning sleeve 34, which is fixedly installed at the rear end of the inner cavity of the housing 1. The end of the rack 1 32 away from the metal mesh 46 is slidably connected in the positioning sleeve 34.

[0031] The positioning assembly 4 includes an air pipe 41, which is fixedly mounted at the rear end of the inner cavity of the shell 1, and a moving rod 42 is slidably connected to the end of the air pipe 41 away from the gear 1. A spring 43 is fixedly mounted between the top end of the air pipe 41 and the top end of the push rod 33, and a connecting frame 44 is fixedly mounted at the bottom end of the moving rod 42. A rubber damping ring 45 is fixedly mounted at the bottom end of the air pipe 41, and a metal mesh 46 is fixedly mounted in the middle of the connecting frame 44. The positioning assembly 4 also includes a positioning rod 47, which is fixedly mounted at the front end of the inner cavity of the shell 1, and the front end of the connecting frame 44 is slidably connected to the positioning rod 47. The rubber damping ring 45 is sleeved on the outside of the moving rod 42 and fits with the moving rod 42. The metal mesh 46 is located above the metal conveyor mesh chain 23, and the push rod 33 is movably connected to the end of the air pipe 41 close to the gear 1.

[0032] The working principle and beneficial effects of the above technical solution are as follows:

[0033] The casting 99 to be cleaned is placed on the side of the top of the metal conveyor mesh chain 23 away from the motor 21, and the motor 21 is started. The motor 21 drives the transmission sprocket 22 to rotate, and then drives the metal conveyor mesh chain 23 to rotate, so that the metal conveyor mesh chain 23 drives the casting 99 to be cleaned and the toothed chain 24 (the toothed chain 24 is a rack connected in series with an articulation, which is a prior art and will not be described in detail here) to move in the direction of the motor 21. When the toothed chain 24 moves to the bottom end of the gear 1 31, the toothed chain 24 meshes with the gear 1 31, driving the gear 1 31 to rotate, and the gear 1 31 drives the rack 1 32 and the push rod 33 to move upward as a whole. When the push rod 33 moves upward in the air pipe 41, the gas in the air pipe 41 is pushed toward the moving rod 42, and then the moving rod 42 is pushed downward to drive the metal mesh 46 to move; at the same time, the water pump connected to the rear end of the rotating tube 61 is turned on to deliver the cleaning liquid to perform the cleaning operation, so that the high-pressure water of the high-pressure nozzle 62 cleans the casting 99.

[0034] When the metal mesh 46 contacts the casting 99, the metal mesh 46 is blocked and cannot move downward, so it applies pressure to the casting 99, fixing the position of the casting 99, thereby improving the cleaning effect;

[0035] When the toothed chain 24 leaves the gear 1 31, the motor 21 stops, and the pressure of the gas in the air pipe 41 and the elasticity of the spring 43 jointly drive the push rod 33 to move downward. During this process, due to the damping between the moving rod 42 and the rubber damping ring 45, the moving rod 42 will not move up immediately, so that the casting 99 is continuously fixed during the flushing process, preventing the casting 99 from moving after being impacted by the high-pressure water, ensuring that the high-pressure water can fully exert pressure on the casting 99, and improving the cleaning effect; when the air pressure in the air pipe 41 returns to normal pressure, the elastic force of the spring 43 alone drives the push rod 33 to move downward, and the moving rod 42 will drive the metal mesh 46 to move upward, so that the metal mesh 46 is separated from the casting 99, and the cleaning of this batch of castings 99 is completed;

[0036] When cleaning a higher casting 99, the descending distance of the metal mesh 46 will become shorter, and it will contact the casting 99 in advance. After the push rod 33 moves up, the pressure in the air pipe 41 will increase. When cleaning a lower casting 99, the downward moving distance of the metal mesh 46 is equivalent to that in the state of the higher casting 99. After the push rod 33 moves up, the pressure in the air pipe 41 is smaller than that in the state of the higher casting 99, and the air pipe 41 is still in a high-pressure state. Therefore, the thrust received by the push rod 33 in the process of moving downward will experience: the joint downward push of the air pressure and the elastic force of the spring 43 changes to the single downward push of the elastic force of the spring 43. Therefore, it can be adapted to castings 99 of different heights, thereby increasing the scope of application of the device.

[0037] Example 2:

[0038] like Figures 2 to 4 and Figure 6 As shown, the present invention provides a cleaning device for processing a casting 99, wherein a swing assembly 5 is provided at the rear side of the inner cavity of the shell 1, and the swing assembly 5 includes a second rack 51, which is fixedly mounted on the top end of the first rack 32, and a second gear 52 is rotatably connected to the rear side of the inner cavity of the shell 1, and an incomplete gear 53 is fixedly mounted on the rear end of the second gear 52, and a rack 3 55 is provided at the rear end of the inner cavity of the shell 1, and a reciprocating rack 54 is fixedly mounted on the bottom end of the rack 3 55, and a slide rail 56 is fixedly mounted at the rear end of the inner cavity of the shell 1, and the rear end of the rack 3 55 is slidably connected to the slide rail 56, and the length of the slide rail 56 is the same as the length of the top end of the shell 1, the second gear 52 is meshed with the second rack 51, and the incomplete gear 53 is located in the middle of the reciprocating rack 54 and meshes with the reciprocating rack 54;

[0039] A cleaning assembly 6 is provided at the top of the inner cavity of the shell 1, and the cleaning assembly 6 includes a rotating tube 61, which is rotatably connected to the top of the shell 1. A high-pressure nozzle 62 is fixedly installed at the bottom end of the rotating tube 61, and a gear ring 63 is fixedly installed at the rear end of the rotating tube 61. The bottom end of the gear ring 63 is engaged with the rack three 55, and the high-pressure nozzle 62 is located above the metal mesh 46.

[0040] The working principle and beneficial effects of the above technical solution are as follows:

[0041] The cleaning fluid that enters the rotating tube 61 will enter the high-pressure nozzle 62 and be sprayed out by the high-pressure nozzle 62 during the cleaning process. In addition, since the push rod 33 is in a downward state during the cleaning process, the push rod 33 can drive the rack 2 51 to move downward and drive the gear 2 52 to rotate, thereby driving the incomplete gear 53 to rotate. By respectively meshing the incomplete gear 53 with the upper and lower ends of the reciprocating rack 54, the reciprocating rack 54 and the rack three 55 can be driven to reciprocate in the horizontal direction. Since the rack three 55 is meshed with the bottom end of the gear ring 63, when the rack three 55 moves back and forth laterally, the gear ring 63 and the rotating tube 61 can be driven to swing back and forth, so that the high-pressure water column sprayed by the high-pressure nozzle 62 impacts the casting 99 in a multi-angle inclined manner. Compared with the situation in which the water column is directly sprayed downward in the prior art and the side of the casting 99 is not cleaned in place, it can achieve comprehensive and multi-angle effective cleaning of multiple sides of the casting 99, thereby improving the cleaning effect.

[0042] The working principle and use process of the present invention:

[0043] When in use, the casting 99 to be cleaned is placed on the side of the top of the metal conveying mesh chain 23 away from the motor 21, the motor 21 is started, and the water pump connected to the rear end of the rotating tube 61 is turned on to transport the cleaning liquid to perform the cleaning operation. The motor 21 drives the transmission sprocket 22 to rotate, thereby driving the metal conveying mesh chain 23 to rotate, so that the metal conveying mesh chain 23 drives the casting 99 to be cleaned to move in the direction of the motor 21. When the metal conveying mesh chain 23 rotates, when the tooth chain 24 moves to the bottom end of the gear 1 31, it will mesh with the gear 1 31, thereby driving the gear 1 31 to rotate, and the rack 1 32 is driven to move upward as a whole through the gear 1 31. When the rack 1 32 moves upward, it will drive the push rod 33 and the rack 2 51 to move upward together;

[0044] When the push rod 33 moves upward in the air pipe 41, it compresses the spring 43, pushing the air in the air pipe 41 toward the motor 21, thereby pushing the moving rod 42 to move the connecting frame 44 and the metal mesh 46 downward. During this process, the rubber damping ring 45 damps the moving rod 42, causing it to move slowly downward.

[0045] When the rack 2 51 moves upward, the meshing of the rack 2 51 and the gear 2 52 drives the gear 2 52 and the incomplete gear 53 to rotate together. The incomplete gear 53 periodically meshes with the upper and lower ends of the reciprocating rack 54 in the reciprocating rack 54, thereby driving the reciprocating rack 54 to reciprocate laterally, thereby driving the rack 3 55 to reciprocate laterally. The meshing of the rack 3 55 and the gear ring 63 drives the rotating tube 61 to continuously swing.

[0046] When the casting 99 to be cleaned is located below the metal mesh 46, the motor 21 stops, the gear 1 31 is separated from the toothed chain 24, and the gear 1 31 and the toothed chain 24 stop meshing. At this time, the metal mesh 46 presses on the top of the casting 99 to be cleaned, fixing the casting 99 to be cleaned. The gas in the air pipe 41 is in a compressed state, and the water pump on the rear side of the housing 1 is started to pump the cleaning liquid into the rotating tube 61 and spray it out through the high-pressure nozzle 62.

[0047] After gear 1 31 stops meshing with the toothed chain 24, gear 1 31 loses its lock and can rotate in the opposite direction. Under the combined action of the elastic action of the compressed spring 43 and the air pressure of the compressed gas in the top part of the air pipe 41, the push rod 33 is directly pushed downward. The downward movement of the push rod 33 drives the rack 1 32 downward, driving gear 1 31 to reverse and simultaneously drives the rack 2 51 downward, causing the rack 2 51 to drive gear 2 52 to rotate in the opposite direction, thereby driving the incomplete gear 53 to rotate and drive the rack 3 55 to reciprocate laterally, thereby driving the rotating tube 61 to swing back and forth. At this time, the cleaning liquid sprayed from the high-pressure nozzle 62 can impact the casting 99 at a cleaning angle to clean the casting 99.

[0048] After the air pressure at the top of the air pipe 41 returns to normal pressure, the push rod 33 does not move down completely. At this time, the push rod 33 moves down under the action of the elastic force of the spring 43, and then the movable rod 42 is pulled up to drive the metal mesh 46 away from the cleaned casting 99. During this process, the high-pressure nozzle 62 continues to swing and spray water. However, the casting 99 has already been impact-cleaned before this process. In this process, the casting 99 is cleaned again to keep the surface of the casting 99 clean.

[0049] After cleaning is completed, the motor 21 is started again to deliver the cleaned casting 99.
