Description

Technical Field

[0001] This utility model relates to the field of casting post-processing technology, specifically a mechanical casting gap cleaning mechanism. Background Technology

[0002] Cast iron pump and valve components are the core pressure-bearing and flow-guiding parts of pumps and valves in fluid machinery. Their manufacturing quality directly affects the sealing performance, corrosion resistance, and service life of the entire machine. Piston rings are installed on their inner walls to seal the gap between the piston and the cylinder to prevent fluid leakage. They also have the functions of guiding and scraping off impurities. However, after casting, molding sand, flash, burrs, or oxide scale may remain on the inner wall. These impurities can cause piston ring jamming or accelerated wear, and may also lead to seal failure and internal leakage.

[0003] Piston rings are located deep within the casting, with a large length-to-diameter ratio and a narrow inlet throat. They are easily chipped by manual or semi-automatic tools. Conventional manual cleaning makes it difficult to control the force, which may damage the sealing strip or leave high spots, affecting subsequent grinding and sealing. Cleaning them using existing methods is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for cleaning gaps in mechanical castings to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a mechanical casting gap cleaning mechanism, comprising,

[0006] A limiting frame is provided, with a water storage shell fixedly connected to its top. A fixing ring is rotatably connected to the top of the water storage shell. Two nozzles are fixedly connected to the top of the fixing ring. A positioning ring is rotatably connected to the top of the water storage shell. Both nozzles pass through the positioning ring and are fixedly connected to it. Two cleaning brushes are rotatably connected to the top of the positioning ring. The cleaning brushes and nozzles are distributed alternately.

[0007] Furthermore, two fixing frames are symmetrically fixed to the top of the limiting frame, and the opposite ends of the two fixing frames are fixed to the outer wall of the water storage shell. A sleeve is provided above the limiting frame, and the two fixing frames pass through the sleeve and are fixed to it.

[0008] Furthermore, a fixing plate is fixedly connected to the top of the limiting frame, and a water pump is fixedly connected to one side of the fixing plate. The water outlet of the water pump passes through the sleeve and is fixedly connected to the water storage shell.

[0009] Furthermore, the top of the limiting frame is slidably connected to two support frames, which are symmetrically distributed.

[0010] Furthermore, a connecting ring is fixedly sleeved on the outer wall of the positioning ring, and a toothed ring is fixedly sleeved on the outer wall of the connecting ring. A motor is fixedly connected to the top of one of the fixing frames, and a gear is fixedly sleeved on the output end of the motor. The gear meshes with the toothed ring.

[0011] Furthermore, two positioning frames are symmetrically fixed to the top of the limiting frame, and two C-shaped frames are slidably connected between the tops of the two positioning frames. The bottom of the C-shaped frames is fixed with a retainer for limiting the body of the pump valve cast iron part.

[0012] Furthermore, a bidirectional lead screw is rotatably connected inside one of the positioning frames. The bidirectional lead screw passes through two C-shaped frames, and adjacent sections of the C-shaped frames are screwed together with the bidirectional lead screw. One end of the bidirectional lead screw extends through the positioning frame to its outside. A locking block is fixedly sleeved on one end of the bidirectional lead screw. Multiple locking slots are equidistantly opened on the outer wall of the locking block. A plug rod is slidably connected to one side of the positioning frame. A spring is fixedly connected between the plug rod and the positioning frame. The plug rod can be movably engaged with the adjacent locking slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The rotating locking block drives the two C-shaped frames to move closer together, causing the positioning frame to engage and limit the position of the pump and valve cast iron body. The water pump is started to pump water into the water storage tank and spray it out through two nozzles. The motor is started to drive the positioning ring to rotate, and two cleaning brushes scrape and clean the inside of the limiting frame. The cleaning brushes also spray water onto the cleaning area inside the pump and valve cast iron body to remove dust and debris. The pump and valve cast iron body is stably limited, and the cleaning force is constant to prevent damage. During the process, the sleeve can gather and guide the water to prevent water splashing and facilitate use. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a mechanical casting gap cleaning mechanism, including a limiting frame 10, a water storage shell 11 fixedly connected to the top of the limiting frame 10, a fixing ring 112 rotatably connected to the top of the water storage shell 11, two nozzles 111 fixedly connected to the top of the fixing ring 112, a positioning ring 12 rotatably connected to the top of the water storage shell 11, both nozzles 111 passing through the positioning ring 12 and fixedly connected thereto, and two cleaning brushes 121 rotatably connected to the top of the positioning ring 12, the cleaning brushes 121 and the nozzles 111 being distributed alternately.

[0023] In specific implementation, before installing the pump and valve cast iron body 20, the two support frames 103 are brought close to each other, and the pump and valve cast iron body 20 is placed on top of the two support frames 103 for auxiliary support. Then, rotating the locking block 133 can drive the bidirectional screw 132 to rotate, thereby driving the two C-shaped frames 131 to move closer to each other, driving the locking seat 137 to engage and limit the pump and valve cast iron body 20. Then, the insertion rod 135 can be inserted into the adjacent locking slot 134 to limit the angle of the bidirectional screw 132, which facilitates the quick limiting of the two locking seats 137, making it more stable during subsequent cleaning.

[0024] The water pump 102 is connected to the water supply source. The water pump 102 is started to pump water into the water storage tank 11 and spray it out through two nozzles 111. The motor 106 is started to drive the gear 107 to rotate. The gear 107 and the gear ring 123 drive the positioning ring 12 to rotate, thereby scraping and cleaning the inside of the limit frame 10 through two cleaning brushes 121. The cleaning brushes 121 drive the cleaning brushes to spray water on the cleaning position inside the pump valve cast iron body 20, removing dust and debris inside the pump valve cast iron body 20. During the process, the sleeve 105 can gather and guide the water to prevent water splashing and guide the sewage downward.

[0025] See Figure 1-5 The top of the limiting frame 10 is symmetrically fixed with two fixing frames 104. The opposite ends of the two fixing frames 104 are fixed to the outer wall of the water storage shell 11. A sleeve 105 is provided above the limiting frame 10. The two fixing frames 104 pass through the sleeve 105 and are fixed to it.

[0026] A fixing plate 101 is fixedly connected to the top of the limiting frame 10, and a water pump 102 is fixedly connected to one side of the fixing plate 101. The water outlet end of the water pump 102 passes through the sleeve 105 and is fixedly connected to the water storage shell 11.

[0027] A connecting ring 122 is fixedly sleeved on the outer wall of the positioning ring 12, and a gear ring 123 is fixedly sleeved on the outer wall of the connecting ring 122. A motor 106 is fixedly connected to the top of one of the fixing brackets 104, and a gear 107 is fixedly sleeved on the output end of the motor 106. The gear 107 meshes with the gear ring 123.

[0028] In practice, the sleeve 105 and the water storage tank 11 and its components are fixed by two fixing brackets 104. The water pump 102 is connected to the water supply source. The water pump 102 is started to pump water into the water storage tank 11 and spray it out through two nozzles 111. The motor 106 is started to drive the gear 107 to rotate. The gear 107 and the gear ring 123 drive the positioning ring 12 to rotate, thereby scraping and cleaning the inside of the limiting bracket 10 by two cleaning brushes 121. The cleaning brushes 121 spray water on the cleaning position inside the pump valve cast iron body 20 to remove dust and debris inside the pump valve cast iron body 20. During the process, the sleeve 105 can gather and guide the water to prevent water splashing and guide the sewage downward.

[0029] See Figure 1 The top of the limiting frame 10 has two support frames 103 that are slidably connected, and the two support frames 103 are symmetrically distributed.

[0030] In practice, before installing the pump and valve cast iron body 20, the two support frames 103 are brought close to each other, and the pump and valve cast iron body 20 is placed on top of the two support frames 103 for auxiliary support. Then, the two C-shaped frames 131 are engaged with the pump and valve cast iron body 20 for stable positioning.

[0031] See Figure 1-3 Two positioning frames 13 are symmetrically fixed to the top of the limiting frame 10. Two C-shaped frames 131 are slidably connected between the tops of the two positioning frames 13. A card seat 137 for limiting the pump valve cast iron body 20 is fixed to the bottom of the C-shaped frame 131.

[0032] One of the positioning frames 13 is internally rotatably connected to a bidirectional lead screw 132, which passes through two C-shaped frames 131. The adjacent sections of the C-shaped frames 131 and the bidirectional lead screw 132 are screwed together. One end of the bidirectional lead screw 132 passes through the positioning frame 13 and extends to its outside. A locking block 133 is fixedly sleeved on one end of the bidirectional lead screw 132. Multiple slots 134 are equidistantly opened on the outer wall of the locking block 133. A plug rod 135 is slidably connected to one side of the positioning frame 13. A spring 136 is fixedly connected between the plug rod 135 and the positioning frame 13. The plug rod 135 can be movably engaged with the adjacent slot 134.

[0033] In practice, the two positioning frames 13 limit the position of the shaped frame 131, thereby limiting the horizontal sliding of the two card seats 137. Rotating the card block 133 can drive the bidirectional screw 132 to rotate, thereby driving the two shaped frames 131 to move closer to each other, causing the card seats 137 to engage and limit the position of the pump and valve cast iron body 20. Then, the insertion rod 135 can be inserted into the adjacent slot 134 to limit the angle of the bidirectional screw 132, which facilitates the quick limiting of the two card seats 137 and makes subsequent cleaning more stable.

[0034] Working principle: Before installing the pump and valve cast iron body 20, the two support frames 103 are brought close to each other, and the pump and valve cast iron body 20 is placed on top of the two support frames 103 for auxiliary support. Then, rotating the locking block 133 can drive the bidirectional screw 132 to rotate, thereby driving the two C-shaped frames 131 to move closer to each other, driving the locking seat 137 to engage and limit the pump and valve cast iron body 20. Then, the insertion rod 135 can be inserted into the adjacent locking groove 134 to limit the angle of the bidirectional screw 132, which facilitates the quick limiting of the two locking seats 137, making it more stable during subsequent cleaning.

[0035] The water pump 102 is connected to the water supply source. The water pump 102 is started to pump water into the water storage tank 11 and spray it out through two nozzles 111. The motor 106 is started to drive the gear 107 to rotate. The gear 107 and the gear ring 123 drive the positioning ring 12 to rotate, thereby scraping and cleaning the inside of the limit frame 10 through two cleaning brushes 121. The cleaning brushes 121 drive the cleaning brushes to spray water on the cleaning position inside the pump valve cast iron body 20, removing dust and debris inside the pump valve cast iron body 20. During the process, the sleeve 105 can gather and guide the water to prevent water splashing and guide the sewage downward.
