Description

Technical Field

[0001] The present invention relates to the technical field of sand removal treatment for castings, and particularly to an outer surface sand removal treatment device for motor housing castings. Background Art

[0002] The casting process of the motor housing mainly includes steps such as molding, casting, cooling and demolding, and sand removal treatment. In the molding stage, corresponding molds need to be made according to the shape and size requirements of the motor housing first, and then molten metal materials are poured into the molds. After cooling and solidification, a blank part of the motor housing is formed. After demolding the blank part, a sand removal treatment device is required, and its main function is to remove the molding sand attached to the blank part, thereby improving the surface quality of the motor housing and preparing for subsequent machining and assembly.

[0003] The existing sand removal treatment devices for castings mainly shake off the molding sand adhered to the surface of the motor housing casting by continuous vibration during use. However, during the treatment process, since the bottom of the casting will inevitably come into contact with and adhere closely to the vibrating screen of the sand removal treatment device, it is difficult to completely remove the molding sand at the bottom of the casting through vibration, and it may cause wear to the bottom of the casting. Moreover, if only the casting is vibrated in a horizontal state, it is also difficult to ensure that all the molding sand on the top of the casting will fall off the casting, resulting in the need for manual or other machinery to clean the top of the casting after sand removal treatment of the casting, thus leading to a poor sand removal effect of the sand removal treatment device for castings.

Detailed implementation manners

[0032] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0033] Embodiment 1: An outer layer sand removal treatment device for a motor housing casting, as Figures 1 - 5 shown, comprising a machine frame 1, a vibration frame 11, a vibration motor 12, an orifice plate 13, a top frame 14, an electric push rod 15, and a leakage hole 16. A vibration frame 11 is slidably connected to the top of the machine frame 1. A collection frame is slidably connected to the middle of the vibration frame 11. Vibration motors 12 are fixedly connected to both the left and right sides of the lower part of the vibration frame 11. An eccentric wheel is fixedly connected to the output end of the vibration motor 12. An orifice plate 13 is fixedly connected to the inside of the vibration frame 11. A top frame 14 is slidably connected to the middle of the orifice plate 13. Uniformly distributed leakage holes 16 are formed in the middle of the top frame 14. Electric push rods 15 are fixedly connected to both the left and right sides of the inside of the vibration frame 11. The telescopic ends of the electric push rods 15 are fixedly connected to the top frame 14.

[0034] When a worker needs to perform shakeout treatment on the motor housing casting, the casting can be first placed on the top of the orifice plate 13 within the vibration frame 11, and then the vibration motor 12 can be started. Since an eccentric wheel is installed at the output end of the vibration motor 12, the vibration motor 12 will drive the eccentric wheel to rotate and cause vibration, thereby making the vibration frame 11, the orifice plate 13, and the casting vibrate. In this way, the molding sand adhered to the top, side, and part of the bottom of the casting can be shaken off through vibration, thereby improving the surface quality of the motor housing casting. The shaken-off molding sand will pass through the round holes on the orifice plate 13 or the leakage holes 16 on the top frame 14 and fall into the collection box inside the vibration frame 11. And at this time, the horizontal height of the top of the top frame 14 is lower than that of the orifice plate 13. When enough molding sand is collected in the collection box, the collection box can be pulled out forward and cleaned. During the shakeout treatment process, the worker can also start the electric push rod 15 in a timely manner. The electric push rod 15 will drive the top frame 14 to move upward and jack up the casting, thereby replacing the orifice plate 13 to support the casting. At this time, the molding sand adhered to the part of the casting that originally contacted the orifice plate 13 can be removed through vibration. In this way, the contact part between the bottom of the casting and the equipment can be switched, so as to prevent the molding sand from being clamped between the bottom of the casting and the equipment and being difficult to be completely removed through vibration, and to prevent the casting from having long-term severe friction with the bottom molding sand and being worn. After the shakeout treatment is completed, the electric push rod 15 can be used to drive the top frame 14 and the casting to move downward and reset first, and then the vibration motor 12 can be turned off and the processed motor housing casting can be taken out.

[0035] Embodiment 2: On the basis of Embodiment 1, as Figure 6 and Figure 7 shown, it further includes a lifting mechanism. The lifting mechanism is arranged on the vibration frame 11. The lifting mechanism includes a rotating plate 2, a first electric slide rail 21, a lifting frame 22, a guide rail 23, an elastic vibration damping plate 24, and vibration balls 25. The rotating plate 2 is rotatably connected to the upper part of the left side of the vibration frame 11. The front and rear parts on the right side of the vibration frame 11 are both fixedly connected with a first electric slide rail 21. A lifting frame 22 is fixedly connected between the sliders of the front and rear first electric slide rails 21. The lifting frame 22 is in pressing fit with the rotating plate 2. The front and rear sides inside the vibration frame 11 are both fixedly connected with a guide rail 23. The outer part of the guide rail 23 is slidably connected with an axially distributed elastic vibration damping plate 24. A bolt is threadedly connected to the top of the elastic vibration damping plate 24. The bolt is in pressing fit with the guide rail 23. The inside of the elastic vibration damping plate 24 is movably connected with two left and right vibration balls 25.

[0036] As Figure 6 and Figure 7 shown, a uniformly distributed round hole is formed in the middle of the rotating plate 2, and an axially distributed strip-shaped limiting block is fixedly connected to the top.

[0037] When placing the motor casing casting, the worker can first place the casting on the top of the rotating plate 2, and then install an appropriate number of elastic vibration guide plates 24 on the guide rail 23 according to the number of castings. When the elastic vibration guide plate 24 is moved to the appropriate position along the guide rail 23, the position of the elastic vibration guide plate 24 can be fixed by forward tightening the bolts. In addition, during the movement, the worker can first flip the elastic vibration guide plate 24 upward to a certain angle and deform it according to the size of the motor casing casting, and then use the reset elastic force of the elastic vibration guide plates 24 on the front and rear sides to flexibly clamp and fix the placed casting, so that the casting can better contact with the vibration frame 11 and ensure the vibration effect and uniformity. When the elastic vibration guide plate 24 vibrates continuously with the guide rail 23 and the vibration frame 11 and other components, the vibration balls 25 inside the elastic vibration guide plate 24 will also vibrate continuously and collide with each other, thereby causing additional vibration and transmitting the vibration to the casting through the elastic vibration guide plate 24, thereby enhancing the vibration effect of the casting. During the sand falling process, the worker can also start the The first electric slide rail 21 is driven. If the top of the casting in the placed state is in a horizontal state, the lifting frame 22 can be driven to move upward by the first electric slide rail 21. The upward movement of the lifting frame 22 will squeeze and drive the rotating plate 2 to rotate slightly upward. At this time, the casting and the elastic vibration guide plate 24 will also rotate or deform with the rotating plate 2 and become tilted. In this way, the placement angle of the casting can be adjusted as needed and the top of the casting can be tilted to assist the molding sand to slide down, thereby preventing some molding sand from remaining on the plane at the top of the casting. And secondary cleaning is required, wherein the elastic vibration guide plate 24 and the strip limit blocks on the rotating plate 2 can limit and fix the casting, thereby preventing the casting from moving on the rotating plate 2 and colliding with other components. After the sand falling process is completed, the lifting frame 22 is driven downward and reset by the first electric slide rail 21, and the rotating plate 2 and the casting are also rotated downward and reset. Then, the elastic vibration guide plate 24 is released from the fixation of the battery casing casting and the casting is taken out. The elastic vibration guide plate 24 is then restored to its original state under the action of its own elasticity.

[0038] like Figure 8 and Figure 9 As shown, a closing mechanism is also included, which is arranged on the vibration frame 11. The closing mechanism includes a sealing cloth 3, a pulling frame 31, a limiting frame 32, a rotating rod 33 and a mounting frame 34. The mounting frame 34 is fixed to the top left side of the vibration frame 11. The upper part of the mounting frame 34 is rotatably connected to the rotating rod 33, and the sealing cloth 3 is wound around the outer side of the rotating rod 33. The upper part of the vibration frame 11 is slidably connected to the pulling frame 31, and the pulling frame 31 is fixed to the lead-out end of the sealing cloth 3. The front and rear parts of the right side of the pulling frame 31 are fixed to the limiting frame 32. The front and rear parts of the right side of the vibration frame 11 are provided with card slots, and the limiting frame 32 is card-engaged with the vibration frame 11.

[0039] Before starting the vibration motor 12, the worker can first move the pulling frame 31 and the limiting frame 32 to the right until the limiting frame 32 deforms and inserts into the card slot on the right side of the vibration frame 11. In this way, the pulling frame 31 can be limited and fixed by means of the limiting frame 32 and the card slot. Moreover, when the pulling frame 31 moves to the right, the sealing cloth 3 wound around the rotating rod 33 will be pulled out and the opening at the top of the vibration frame 11 will be closed by means of the sealing cloth 3, thus preventing the dust generated by sand falling from leaking outwards and affecting the external environment and the physical health of the workers. During this period, the rotating rod 33 will also rotate forward under the drive of the sealing cloth 3. After the sand falling treatment is completed, the worker can rotate the rotating rod 33 in the reverse direction and rewind the sealing cloth 3, and the pulling frame 31 and the limiting frame 32 will also move leftward and reset under the drive of the sealing cloth 3.

[0040] As Figure 10 and Figure 11 shown, it also includes a suction mechanism. The suction mechanism is arranged on the vibration frame 11. The suction mechanism includes a suction fan 4, a guide air pipe 41, a suction plate 42 and a spray plate 43. The spray plate 43 is fixedly connected to the inside of the vibration frame 11. Suction plates 42 are fixedly connected to both the left and right sides inside the vibration frame 11. A guide air pipe 41 is fixedly connected and communicated between the suction plate 42 and the spray plate 43. The upper part of the guide air pipe 41 is fixedly connected with a suction fan 4.

[0041] As Figure 10 and Figure 11 shown, a filter screen is fixedly connected to the top of the suction plate 42.

[0042] When performing sand falling treatment on the motor housing casting, the worker can also start the suction fan 4. Since the vibration frame 11 will vibrate under the action of the vibration motor 12, the collection box on the vibration frame 11 and the collected molding sand will also vibrate and stir up dust. The suction fan 4 can absorb the stirred-up dust through the suction plate 42 and make the dust adhere to the filter screen. The air absorbed by the suction fan 4 will enter the spray plate 43 through the guide air pipe 41 and be sprayed downward, thus preventing the dust from diffusing upward and re-adhering to the surface of the casting. After the sand falling treatment is completed, just turn off the suction fan 4.

[0043] As Figure 12 and Figure 13As shown in the figure, it further includes a scraping mechanism. The scraping mechanism is arranged on the vibration frame 11. The scraping mechanism includes a second electric slide rail 5, a moving frame 51, a telescopic block 52, a guiding block 53 and a scraping plate 54. The two second electric slide rails 5 are respectively fixedly connected to the front and rear sides inside the vibration frame 11. A moving frame 51 is fixedly connected between the sliders of the front and rear second electric slide rails 5. Telescopic blocks 52 distributed longitudinally in the front and rear directions are fixedly connected to both the left and right sides of the moving frame 51. A scraping plate 54 is fixedly connected between the telescopic ends of the longitudinally distributed telescopic blocks 52 on the same side. Guiding blocks 53 are fixedly connected to both the front and rear sides of the top of the suction plate 42. The scraping plate 54 is slidably connected to the adjacent guiding block 53, and the scraping plate 54 is in contact and cooperation with the suction plate 42.

[0044] After the sand falling treatment is completed, the worker can also start the second electric slide rail 5. The second electric slide rail 5 will drive the moving frame 51, the telescopic block 52 and the scraping plate 54 to move up and down. Since the telescopic block 52 can be telescopic and the guiding block 53 is inclined, the scraping plate 54 will move up and down along the guiding block 53 and scrape and clean the dust on the filter screen of the suction plate 42, and make the dust fall downward into the collection box, so as to avoid the filter screen being blocked by dust and affecting the dust suction effect of the equipment. After the cleaning is completed, just turn off the second electric slide rail 5.

[0045] The above are only examples of the present invention and are not used to limit the present invention. All equivalent replacements made within the principle of the present invention shall be included in the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art in the technical field of the specialty.
