Description

Technical Field

[0001] The present invention relates to the technical field of part cleaning equipment, and particularly relates to an internal cavity cleaning equipment for part casting. Background Art

[0002] Part casting is a manufacturing process in which metal is melted into a liquid and poured into a mold of a specific shape to cast a part. After it cools and solidifies, a part or blank with the required shape and properties is obtained. Since dirt, dust or other impurities are likely to remain inside the shaft parts after casting, it is necessary to use cleaning equipment to clean the inside of the shaft parts to ensure the smoothness of the inner cavity of the parts. Currently, when cleaning parts, a cleaning chamber and a water supply component in the cleaning equipment are used to vibrate and clean a batch of parts in the cleaning chamber. Since the parts are close to each other in the cleaning chamber and are likely to collide with each other during vibration, the mutual displacement of the parts makes it difficult to cover all areas during cleaning, resulting in the dirt attached to the inner cavity of the parts being difficult to quickly remove, prolonging the cleaning time required, and reducing the cleaning efficiency of the equipment for the parts. Summary of the Invention

[0003] The purpose of the present invention is to provide an internal cavity cleaning equipment for part casting to solve the above deficiencies in the technology.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An internal cavity cleaning equipment for part casting, comprising:

[0005] A cleaning chamber and a workpiece, and the cleaning chamber is used to clean the inner cavity of the workpiece. An installation box is fixed on one side of the cleaning chamber;

[0006] The cleaning assembly is used to clean workpieces placed in a circular array in the cleaning chamber and effectively remove the attachments in the inner cavity of the workpieces. The cleaning assembly includes a mounting disk rotatably installed in the cleaning chamber, a centering groove opened outside the mounting disk for storing the workpieces, and a first cleaning brush arranged in the middle of the centering groove for cleaning the inner cavity of the workpieces. A centering cleaning groove communicating with the inside of the centering groove is opened on one side of the mounting disk for the first cleaning brush to stretch. An elastic component is arranged outside the mounting disk, and the elastic component is used to limit the workpiece in the centering groove without being too tight and form floating of the workpiece in the centering groove. A moving support component for driving the first cleaning brush to move is arranged in the mounting box, and the first cleaning brush is separated from the inside of the centering cleaning groove and attached to the outside of the mounting disk. A depth cleaning component is arranged on the moving support component for cleaning the impurities outside the first cleaning brush, so that the first cleaning brush and the inner cavity of the workpiece are kept clean. A plurality of centering grooves are opened on the mounting disk, and the number of the first cleaning brushes is equal to that of the centering grooves. Moreover, the sizes of the first cleaning brushes are different, and each first cleaning brush is attached to the inner cavity of the workpiece, so that the relative extrusion forces generated by the contact between each first cleaning brush and the inner cavity of the workpiece are different. Therefore, the workpieces and the mounting disk are arranged in a circular array. When the mounting disk rotates clockwise from the starting point and returns after rotating one circle inside the cleaning chamber, the workpieces are kept flowing inside the cleaning chamber under the rotation of the mounting disk, and the position of the workpieces inside the cleaning chamber is changed with each rotation, so that one centering groove and one first cleaning brush are rotated. This is beneficial for the first cleaning brushes of different sizes to clean the inner cavity of the workpiece once. The rotation of the mounting disk produces a dynamic effect on the workpieces inside the cleaning chamber, which helps the first cleaning brush to penetrate into the inner cavity of the workpiece, effectively remove dirt and residues, and improve the cleaning quality.

[0007] Preferably, a first servo motor is also installed in the cleaning chamber and the mounting box, and the first servo motor is used to drive the mounting disk to rotate. A moving column is fixed to one end of the first cleaning brush close to the cleaning chamber, and one end of the moving column penetrates through the cleaning chamber and the mounting box. A sealing sleeve is jointly fixed in the cleaning chamber and the mounting box, and the sealing sleeve is sleeved on the moving column. Moreover, the connection between the sealing sleeve and the moving column adopts the connection mode of a piston, so that the moving column reciprocates inside the sealing sleeve without carrying the cleaning water inside the cleaning chamber into the mounting box, ensuring good sealing among the moving column, the sealing sleeve and the cleaning chamber.

[0008] Preferably, the motion support assembly includes a support frame fixed in an installation box, an annular disk fixed at one end of the moving column and a moving frame slidably connected to the outside of the support frame, and the annular disk is located in the installation box and fixed at one end of the moving frame, and a rotating disk is rotatably connected in the support frame, and a reciprocating assembly is provided on the support frame for driving the moving frame and the annular disk to reciprocate; and the moving frame and the annular disk are fixedly connected to each other, so as to keep one end of the moving column in the installation box stable, so that the moving column is in a horizontal state in the cleaning cabin, ensuring that the moving column can maintain stable movement and connection with the first cleaning brush under the action of the motion support assembly.

[0009] Preferably, a positioning block is fixed on the support frame, and a positioning groove for sliding the positioning block is opened at one end of the mobile frame; and the positioning groove and the positioning block are slidably connected to ensure stable movement of the mobile frame outside the support frame, and good stability is maintained between the water drop mobile frame and the support frame.

[0010] Preferably, the reciprocating assembly includes a second servo motor fixed on the support frame, two eccentric wheels fixed at one end of the rotating disk, and a push rod fixed on the movable frame near one of the eccentric wheels, and the second servo motor is used to drive the rotating disk to rotate, a support seat is fixed on the outside of the support frame, a guide column is rotatably sleeved on the support seat, a first interference rod and a second interference rod are respectively fixed on the outside of the guide column, and the outside of the first interference rod is fitted with the other eccentric wheel, a guide column is fixed on the side of the movable frame adjacent to the push rod, and a floating groove for the guide column to slide is provided on the top of the second interference rod; and the push rod is fitted with one of the eccentric wheels, and the two eccentric wheels move in a circle on the rotating disk, so that the two eccentric wheels respectively The first cleaning brush and the mounting plate are alternately fitted with the push rod and the first resistance rod to drive the moving frame to reciprocate along the upper seat of the support frame. At the same time, the rotating disk and the mounting plate maintain synchronous movement, so that the moving frame moves to pre-take out the first cleaning brush from the centering groove, and then the mounting plate rotates to rotate the centering groove. Subsequently, the moving frame is reset to reset the first cleaning brush along the centering groove, and is used to scrape and clean the inner cavity of the workpiece. Then the moving frame, the first cleaning brush and the mounting plate complete the first movement, and reciprocate in turn to avoid mutual interference, and are used to rotate the first cleaning brush to clean the inner cavity of the workpiece; and the first resistance rod and the second resistance rod are combined on the guide column to form an L-shaped structure, which is conducive to the swing of the first resistance rod to drive the guide column to rotate along the support seat.

[0011] Preferably, the deep cleaning component includes a moving ring installed on the moving frame, a cleaning sleeve sleeved on the first cleaning brush, and a long column fixed at one end of the cleaning sleeve. An adapter ear plate is fixed on the moving ring, and one end of the long column passes through the sealing sleeve and extends into the installation box and is fixedly connected to the top of the adapter ear plate. A synchronous component for driving the moving ring to reciprocate is provided on the positioning block; and the long column and the sealing sleeve also adopt a piston connection method, so that a good seal is maintained among the long column, the sealing sleeve and the cleaning chamber, and the cleaning sleeve and the first cleaning brush are staggered, so that the first cleaning brush contacts the cleaning sleeve during movement to remove the dirt on the first cleaning brush, keep the surface of the first cleaning brush clean, prevent the dirt on the surface of the first cleaning brush from polluting the inner cavity of the workpiece after cleaning, and is beneficial to the effective cleaning of the inner cavity of the workpiece by the first cleaning brush.

[0012] Preferably, the synchronous component includes a synchronous block fixed in the moving ring, a first rack installed on one side of the moving frame close to the positioning block, and a gear rotatably connected to one end of the positioning block.

At the same time, when the moving ring moves on the moving frame, it drives the cleaning sleeve and the first cleaning brush to move back and forth in an alternating manner, which is beneficial to the first cleaning brush and the cleaning sleeve constantly contacting their surfaces during the back-and-forth movement, applying repeated frictional force to the dirt existing inside them, reducing the time required for cleaning the dirt on the surface of the first cleaning brush, and thus more effectively removing these stains, and further achieving a better cleaning effect of the first cleaning brush on the inner cavity of the workpiece; at the same time, part of the first rack and the gear are located in the synchronous groove, so that the second rack, the gear and the first rack can maintain a stable connection. At the same time, the gear maintains a proper distance from the moving frame in the synchronous groove to avoid interference between the moving frame moving along the positioning block and the gear, and then enables the first rack, the gear and the second rack to maintain stable transmission, enabling the synchronous component and the reciprocating component to cooperate synergistically, and further improving the flexibility of the equipment.

[0013] Preferably, the tightening and loosening component includes a slot opened outside the installation disc and communicating with the inner part of the centering groove, two tightening arc plates symmetrically installed in the slot, and two fitting grooves opened in the slot for the two tightening arc plates to slide. Centering columns are fixed in the slot and the two fitting grooves. Two floating grooves for the two centering columns to insert are formed on the tightening arc plates. Two springs are commonly installed between the two fitting grooves and the two tightening arc plates, and the two springs are sleeved on the centering columns.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0015] 1. Through the setting of the cleaning component, not only can the workpieces be maintained in a circular array in the cleaning chamber, which is beneficial to keeping an appropriate position between the workpieces, avoiding mutual displacement between the workpieces and making it difficult to cover all areas during cleaning, but also the position of the workpieces in the cleaning chamber can be changed, enabling one centering groove to be rotated with one of the first cleaning brushes. This is conducive to all first cleaning brushes of different sizes being able to clean the inner cavity of the workpiece once, helping to penetrate into the inner cavity of the workpiece and effectively remove dirt and residues, improving the cleaning quality and enhancing the cleaning efficiency of the equipment for parts.

[0016] 2. Through the setting of the moving support component, it can be used to keep the mounting plate, centering groove and the first cleaning brush in synchronous cooperation, which is beneficial to preventing interference from occurring between the mounting plate and the centering groove when they move and the first cleaning brush, ensuring their reciprocating motion with each other. Thus, the first cleaning brush can stably rotate and clean the inner cavity of the workpiece.

[0017] 3. Through the setting of the deep cleaning component, it can make the first cleaning brush contact with the cleaning sleeve during movement, which is beneficial to removing the dirt on the surface of the first cleaning brush, keeping the surface of the first cleaning brush clean, preventing the dirt on the surface of the first cleaning brush from contaminating the inner cavity of the workpiece after cleaning, and further enhancing the effective cleaning of the inner cavity of the workpiece by the first cleaning brush.

[0018] 4. Through the setting of the synchronization component, it can be used to keep the moving ring and the annular disk moving synchronously on the moving frame, reducing unnecessary energy transfer, thereby improving the force transmission efficiency of the equipment. At the same time, when the moving ring moves on the moving frame, it drives the cleaning sleeve and the first cleaning brush to reciprocate alternately. This is beneficial to the first cleaning brush and the cleaning sleeve constantly contacting their surfaces during the back-and-forth movement, being able to apply repeated frictional forces to the dirt existing inside them, reducing the time required for cleaning the dirt on the surface of the first cleaning brush, and thus more effectively removing these stains. Further, it can achieve a better cleaning effect of the inner cavity of the workpiece by the first cleaning brush.

[0019] 5. Through the setting of the tightening and loosening component, it can keep the workpiece floatingly connected in the centering groove, so that the workpiece and the centering groove are not rigidly connected. This can reduce the stress concentration phenomenon generated when the workpiece is installed or taken out, reduce the risk of damage to the workpiece caused by uneven force, facilitate the stable removal of the cleaned workpiece, and improve the flexibility of the equipment.

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] The present invention provides an inner cavity cleaning device for part casting as Figures 1 - 9 shown, including: a cleaning chamber 1 and a workpiece 11, and the cleaning chamber 1 is used to clean the inner cavity of the workpiece 11, and an installation box 12 is fixed on one side of the cleaning chamber 1;

[0040] The cleaning assembly 2, for cleaning the workpieces 11 placed in the cleaning chamber 1 in an annular array, can effectively remove the attachments in the inner cavity of the workpieces 11. The cleaning assembly 2 includes a mounting disk 21 rotatably installed in the cleaning chamber 1, a centering groove 22 opened outside the mounting disk 21 for storing the workpieces 11, and a first cleaning brush 24 arranged in the middle of the centering groove 22 for cleaning the inner cavity of the workpieces 11. A centering cleaning groove 23 communicating with the inside of the centering groove 22 is opened on one side of the mounting disk 21 for the first cleaning brush 24 to stretch. An elastic component 7 is arranged outside the mounting disk 21, and the elastic component 7 is used to limit the workpiece 11 in the centering groove 22 without being too tight, and form a floating state of the workpiece 11 in the centering groove 22. A moving support component 3 for driving the first cleaning brush 24 to move is arranged in the mounting box 12, and the first cleaning brush 24 is disengaged along the centering cleaning groove 23 and attached to the outside of the mounting disk 21. A depth cleaning component 5 is arranged on the moving support component 3 for cleaning the impurities outside the first cleaning brush 24, so that the first cleaning brush 24 and the inner cavity of the workpiece 11 are kept clean; A first servo motor 25 is also installed in the cleaning chamber 1 and the mounting box 12, and the first servo motor 25 is used to drive the mounting disk 21 to rotate. A moving column 27 is fixed at one end of the first cleaning brush 24 close to the cleaning chamber 1, and one end of the moving column 27 penetrates through the cleaning chamber 1 and the mounting box 12. A sealing sleeve 26 is jointly fixed in the cleaning chamber 1 and the mounting box 12, and the sealing sleeve 26 is sleeved on the moving column 27; The elastic component 7 includes a slot 71 opened outside the mounting disk 21 and communicating with the inside of the centering groove 22, two elastic arc plates 72 symmetrically installed in the slot 71, and two fitting grooves 76 opened in the slot 71 for the two elastic arc plates 72 to slide. Centering columns 73 are fixed in the slot 71 and the two fitting grooves 76. Two floating grooves 75 for the two centering columns 73 to be inserted are opened on the elastic arc plates 72. Two springs 74 are jointly installed between the two fitting grooves 76 and the two elastic arc plates 72, and the two springs 74 are sleeved on the centering columns 73; And the two elastic arc plates 72 and the slot 71 and the centering groove 22 form an adjustable inverted V-shaped structure, so that the opening of the slot 71 and the centering groove 22 is adjustable under the action of the two elastic arc plates 72, which is beneficial for the slot 71 and the centering groove 22 to place the workpiece 11 and stably limit it. Moreover, the elastic arc plates 72 are arranged in an arc structure, so that a slope fit is maintained between the elastic arc plates 72 and the workpiece 11, and the convex part in the middle of the elastic arc plates 72 is made of an elastic material, which is convenient for the workpiece 11 to keep squeezing and deforming at the convex position in the middle of the elastic arc plates 72, and is beneficial for the workpiece 11 to slide into the centering groove 22. At the same time, the floating grooves 75 are arranged in an oval shape, so that there is a gap between the floating grooves 75 and the centering columns 73, which is beneficial for floating between the floating grooves 75 and the centering columns 73, ensuring that the elastic arc plates 72 can maintain a lever movement in the slot 71 and the fitting grooves 76.

[0041] The motion support assembly 3 includes a support frame 33 fixed inside the installation box 12, an annular disc 31 fixed at one end of the moving column 27, and a moving frame 32 slidably connected to the outside of the support frame 33. The annular disc 31 is located inside the installation box 12 and fixed to one end of the moving frame 32. A rotating disc 34 is rotatably connected inside the support frame 33. A reciprocating assembly 4 for driving the moving frame 32 and the annular disc 31 to reciprocate is provided on the support frame 33. A positioning block 35 is fixed on the support frame 33, and a sliding positioning groove 36 for the positioning block 35 is formed at one end of the moving frame 32.

[0042] The reciprocating assembly 4 includes a second servo motor 41 fixed on the support frame 33, two eccentric wheels 42 fixed at one end of the rotating disc 34, and a push rod 43 fixed on one side of the moving frame 32 close to one of the eccentric wheels 42. The second servo motor 41 is used to drive the rotating disc 34 to rotate. A support seat 45 is fixed outside the support frame 33. A guide post 46 is rotatably sleeved on the support seat 45. A first contact rod 47 and a second contact rod 48 are respectively fixed on the outside of the guide post 46. The outside of the first contact rod 47 is in contact with the other eccentric wheel 42. A guide post 49 is fixed on one side of the moving frame 32 adjacent to the push rod 43. A floating groove 44 for the guide post 49 to slide is formed at the top of the second contact rod 48.

[0043] When used for cleaning shaft parts:

[0044] The first step: Place the workpiece 11 in the slot 71 and between the two elastic arc plates 72. Then, push the workpiece 11 downward to move it downward along the slot 71. At this time, the outside of the workpiece 11 continuously contacts with the two elastic arc plates 72, and the slope between the outside of the workpiece 11 and the two elastic arc plates 72 is matched. When the outside of the workpiece 11 moves inward along the two elastic arc plates 72 into the centering groove 22, it contacts slowly. Moreover, when the outside of the workpiece 11 contacts the bottom of the two elastic arc plates 72, extrusion occurs and the two elastic arc plates 72 are pushed to rotate along the slot 71, so that the two floating grooves 75 opened on the elastic arc plates 72 slide with the two centering columns 73, which is used to make the two elastic arc plates 72 perform a lever movement on the slot 71. Thus, the bottoms of the two elastic arc plates 72 approach the two fitting grooves 76, then the tops of the two elastic arc plates 72 approach each other along the slot 71, and then the workpiece 11 moves into the centering groove 22 along the slot 71 and the elastic arc plates 72. As the workpiece 11 moves continuously, its middle part contacts the protruding parts in the middle of the two elastic arc plates 72, causing the protruding parts in the middle of the two elastic arc plates 72 to deform under force, increasing the distance between the two elastic arc plates 72 and the workpiece 11. Then, the middle part of the workpiece 11 slides over the protruding parts in the middle of the two elastic arc plates 72. Subsequently, the workpiece 11 is completely placed in the centering groove 22. Thus, the bottoms of the two elastic arc plates 72 form an adaptive force with the outside of the centering groove 22 under the elastic action of the spring 74, and the protruding parts in the middle of the two elastic arc plates 72 reset to limit the workpiece 11 in the centering groove 22. Therefore, when the workpiece 11 is installed or removed, the stress concentration phenomenon is reduced, facilitating the stable picking and placing of the workpiece 11 that needs to be cleaned or the cleaned workpiece 11.

[0045] The second step: Drive the rotating disk 34 to rotate along the support frame 33 by the second servo motor 41. Then, the rotation of the rotating disk 34 drives the two eccentric wheels 42 to perform circular motion. At this time, the other eccentric wheel 42 contacts the first contact rod 47 and pushes the first contact rod 47 to move. Moreover, the movement of the first contact rod 47 drives the guide post 46 to rotate along the support seat 45, and the contact surface between the first contact rod 47 and the other eccentric wheel 42 is continuously decreasing. Also, the rotation of the guide post 46 drives the second contact rod 48 to rotate along the support seat 45, so that the floating groove 44 slides and contacts with the guide post 49 and pushes the guide post 49 to move leftward. Thus, the leftward movement of the guide post 49 drives the moving frame 32 to move leftward along the support frame 33. As the moving frame 32 moves, the positioning groove 36 opened on one side of it slides with the positioning block 35. Then, the moving frame 32 moves to push the annular disk 31 and drives the moving column 27 to move along the sealing sleeve 26. Subsequently, the moving column 27 pushes the first cleaning brush 24 into the centering cleaning groove 23 and moves into the inside of the workpiece 11 installed in the centering groove 22. Thus, the first cleaning brush 24 is used to clean the inner cavity of the workpiece 11.

[0046] Step 3: Another eccentric wheel 42 slides over the outside of the first contact rod 47 during rotation and moves towards the push rod 43. Immediately afterwards, the other eccentric wheel 42 contacts the push rod 43 and pushes the push rod 43 to move to the right. At this time, the movement of the push rod 43 drives the moving frame 32 to move to the right along the support frame 33, and the guide post 49 slides in the floating groove 44 and pushes the floating groove 44 to drive the second contact rod 48 to swing. Moreover, the movement of the second contact rod 48 drives the guide post 46 to rotate along the support seat 45, causing the first contact rod 47 to move back to its original position. Thus, the movement of the moving frame 32 drives the annular disk 31, the moving column 27, and the first cleaning brush 24 to move to the right. Subsequently, the first cleaning brush 24 moves out of the inner cavity of the workpiece 11 and the centering cleaning groove 23. And there is a gap between one end of the first cleaning brush 24 and the outside of the mounting disk 21. As the first cleaning brush 24 moves out of the centering cleaning groove 23, the other eccentric wheel 42 slides over the outside of the push rod 43, and then one of the eccentric wheels 42 moves closer to the outside of the first contact rod 47. At the same time, the first servo motor 25 drives the mounting disk 21 to rotate in the cleaning chamber 1, causing the position of the workpiece 11 in the cleaning chamber 1 to change. After the first servo motor 25 stops adjusting the position of the mounting disk 21, then after one of the eccentric wheels 42 contacts the first contact rod 47, the first cleaning brush 24 is inserted into the centering cleaning groove 23 again and scrapes and cleans the inner cavity of the workpiece 11 adjusted in the cleaning chamber 1. Through reciprocating motion in sequence, the workpiece 11 can be kept in a circular array in the cleaning chamber 1, which is beneficial for maintaining a proper position between the workpieces 11, can avoid the difficulty in covering all areas during cleaning caused by the mutual displacement between the workpieces 11, and can also change the position of the workpiece 11 in the cleaning chamber 1, enabling one of the centering grooves 22 to be rotated with one of the first cleaning brushes 24. This is beneficial for all first cleaning brushes 24 of different sizes to clean the inner cavity of the workpiece 11 once, helps to penetrate into the inner cavity of the workpiece 11 and effectively remove dirt and residues, improves the cleaning quality, and enhances the cleaning efficiency of the equipment for parts.

[0047] Reference Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9As shown, the deep cleaning component 5 includes a moving ring 51 installed on the moving frame 32, a cleaning sleeve 54 sleeved on the first cleaning brush 24, and a long column 53 fixed at one end of the cleaning sleeve 54, a connecting ear plate 52 is fixed on the moving ring 51, and one end of the long column 53 passes through the sealing sleeve 26 and extends into the installation box 12 and is fixedly connected to the top of the connecting ear plate 52, and a synchronous component 6 for driving the moving ring 51 to reciprocate is provided on the positioning block 35; the synchronous component 6 includes a synchronous block 65 fixed in the moving ring 51, a first rack 62 installed on the side of the moving frame 32 close to the positioning block 35, and a gear 64 rotatably connected to one end of the positioning block 35, and the gear 64 is meshed with the first rack 62, a second rack 63 is fixed to the bottom end of the synchronous block 65, and the second rack 63 is meshed with the gear 64, and a synchronous groove 61 for sliding the second rack 63 is provided at the top of the moving frame 32, and the synchronous groove 61 is L-shaped.

[0048] Through the above technical solution:

[0049] When the first cleaning brush 24 is moving, the moving frame 32 first moves to the left along the positioning block 35, and then the first rack 62 is meshed with the gear 64 for transmission. At this time, the gear 64 rotates in the positioning block 35 and the synchronous groove 61 and meshes with the second rack 63 to drive the second rack 63 to the right along the synchronous groove 61, and the second rack 63 moves to drive the synchronous block 65 to move synchronously, and the synchronous block 65 moves to pull the moving ring 51 to move along the moving frame 32, so that the moving ring 51 moves to drive the connecting ear plate 52 and the long column 53 to move, so that the long column 53 moves along the sealing sleeve 26, and then the long column 53 moves to drive the cleaning sleeve 54 and the first cleaning brush 24 to move alternately, which is conducive to the first cleaning brush 24 and the cleaning sleeve 54 to continuously contact its surface during the back and forth movement, and can apply repeated friction to the dirt inside it, thereby reducing the time required for cleaning the dirt on the surface of the first cleaning brush 24, thereby more effectively removing these stains, and further achieving a better cleaning effect of the first cleaning brush 24 on the inner cavity of the workpiece 11.
