Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of polishing devices, and particularly relates to a polishing device for stainless steel casting production. BACKGROUND

[0002] Stainless steel castings are widely used in kitchen utensils, medical devices, chemical equipment, automobile parts and other fields due to excellent corrosion resistance, mechanical strength and surface gloss. In the production process of stainless steel castings, the polishing process is a key link to ensure the surface quality of products, and the pouring riser, flash burr, scale and machining allowance on the surface of the castings need to be removed through polishing to lay a foundation for subsequent polishing, coating and other processes.

[0003] The existing polishing operation of stainless steel castings is mainly completed by automatic polishing devices. The typical structure includes a rack, a driving motor, a polishing wheel and a dust adsorption mechanism. The polishing wheel, as the core executive component, is driven by the driving motor to rotate at high speed and contact the surface of the casting to achieve grinding. The dust adsorption mechanism is used to collect the metal dust generated during polishing to avoid dust dispersion and environmental pollution.

[0004] The current mainstream dust adsorption mechanism generally adopts an "external downward suction structure", that is, the adsorption assembly (such as a dust collecting hood and an air suction pipeline) is fixedly arranged below or obliquely below the polishing wheel. The dust generated during polishing is sucked into the dust collecting device by a fan to generate negative pressure. In order to ensure the normal contact processing of the polishing wheel and the casting, a certain working gap needs to be reserved between the adsorption assembly and the polishing wheel and the casting to avoid mechanical interference or affect the loading and unloading operation of the workpiece.

[0005] The stainless steel dust generated during polishing has the characteristics of light weight and easy suspension. When the adsorption structure is located below the polishing wheel, the dust needs to be first settled downward and then adsorbed by negative pressure after separating from the polishing area. However, due to the gap between the adsorption assembly and the polishing area, part of the dust will be affected by the airflow disturbance and the polishing wheel rotating airflow and spread to the surrounding during the settling process, resulting in excessive dust concentration in the workshop, which not only pollutes the working environment, but also causes health hazards to the respiratory system of the operator.

[0038] The output shaft of drive motor 2 is provided with fluid conveying assembly, and the fluid conveying assembly is provided with telescopic piece 4 between the frame 1;

[0039] The fluid conveying assembly comprises: shunt pipe 52, shunt structure 53, pipeline 54, filter structure 55, negative pressure fan 56 and driving structure 58;

[0040] The shunt pipe 52 is driven by the telescopic piece 4, is arranged in the output shaft of the drive motor 2 in an axially movable manner, and is rotatably connected between the output shaft of the drive motor 2 and the inside of the output shaft, the shunt pipe 52 is designed to have at least two independent cavities;

[0041] The negative pressure fan 56 is arranged inside the frame 1, the air inlet end of the negative pressure fan 56 is connected with one cavity of the shunt pipe 52 through the pipeline 54 and the filter structure 55, to form a negative pressure adsorption airflow channel; the air outlet end of the negative pressure fan 56 is connected with another cavity of the shunt pipe 52 through the pipeline 54, to form a clean gas backflow channel;

[0042] The shunt pipe 52 is provided with shunt structure 53, the shunt structure 53 interacts with the driving structure 58 arranged on the polishing wheel 3 and rotates with the polishing wheel 3, periodically changes the adsorption state of the air inlet channel 6, and the driving structure 58 drives the filter structure 55 to vibrate synchronously when rotating.

[0043] The stainless steel dust generated in the polishing process in the prior art has the characteristics of light weight and easy suspension, when the adsorption structure is located below the polishing wheel 3, the dust needs to be first settled downward after separating from the polishing area and then be adsorbed by negative pressure, but due to the gap between the adsorption assembly and the polishing area, part of the dust will be diffused to the surrounding during the settling process due to the influence of airflow disturbance and polishing wheel 3 rotation airflow, resulting in that the dust concentration in the workshop exceeds the standard, which not only pollutes the working environment, but also causes health threat to the respiratory system of the operator;

[0044] Therefore, the fluid conveying assembly is arranged to construct a bidirectional airflow circulation system, to realize integrated dust control from direct adsorption at the polishing point, efficient filtration to a clean airflow barrier, to minimize dust diffusion, to improve the working environment, and to reduce the threat to the health of the operator.

[0045] In use, when the negative pressure fan 56 is started, a negative pressure state is formed in one chamber of the shunt pipe 52, at this time, the dust generated by polishing is directly sucked from the polishing point into the air inlet channel 6 of the polishing wheel 3, enters the negative pressure chamber of the shunt pipe 52 through the output shaft of the driving motor 2, and is sent to the filtering structure 55 through the pipeline 54 for purification treatment;

[0046] At the same time, the clean gas purified by the filtering structure 55 enters another chamber of the shunt pipe 52 through another pipeline 54, and is finally discharged from the air outlet of the output shaft into the air inlet channel 6 of the polishing wheel 3, thereby forming a backflush;

[0047] The cooperation of the shunt structure 53 and the driving structure 58 further enhances the dust control effect, when the polishing wheel 3 rotates, the driving structure 58 synchronously drives the shunt structure 53 to move, so that the adsorption state of the air inlet channel 6 changes periodically, and a pulse adsorption effect is generated, avoiding the local airflow turbulence that may be formed by traditional continuous adsorption;

[0048] In addition, the driving structure 58 rotates synchronously to drive the filtering structure 55 to vibrate, which can prevent the filtering material from being blocked by dust, ensure the stability of the filtering efficiency, and at the same time, the vibration can also promote the dust attached to the filtering material to fall off, facilitating subsequent cleaning and recycling.

[0049] In order to realize the above-mentioned embodiment, the driving structure 58 drives the shunt structure 53 to run, and the following solutions are provided, as shown in Figure 3 and Figure 6 The driving structure 58 includes a rotating disc 581, which is rotatably connected to the outside of the convex disc 51 and is clamped with the polishing wheel 3, a sector-shaped connecting plate 583 is fixedly installed on the inner wall of the rotating disc 581, a magnetic attraction piece two 584 is clamped and installed on one end face of the sector-shaped connecting plate 583, an oval ring 582 is clamped and installed on one end face of the rotating disc 581 close to the negative pressure fan 56, a circular rod is clamped and installed on one end face of the oval ring 582 close to the rotating disc 581, and the circular rod is clamped and connected with the rotating disc 581;

[0050] In use, the rotation of the polishing wheel 3 synchronously drives the rotating disc 581 to rotate, the rotating disc 581 drives the sector-shaped connecting plate 583 to rotate when rotating, the sector-shaped connecting plate 583 synchronously drives the magnetic attraction piece two 584 to rotate when rotating, and the oval ring 582 is synchronously driven to rotate at the same time.

[0051] In order to achieve the above-mentioned embodiment, how to make the shunt pipe 52 enter the output shaft of the driving motor 2, so that the gas can flow along the preset direction, the following solutions are provided, as shown in Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The output shaft of the telescopic part 4 is clamped and installed with a convex disc 51, the convex disc 51 is fixedly connected with the shunt pipe 52 near one end of the polishing wheel 3, the shunt structure 53 is clamped and installed inside the shunt pipe 52 and the number is two, the shunt structure 53 includes a screening plate 531, the screening plate 531 is clamped and installed inside the shunt pipe 52, one of the screening plates 531 is provided with a cavity inside, the screening plate 531 and the inner fan-shaped air baffle 532 are provided with positioning holes on one end face, the positioning holes on the screening plate 531 and the inner fan-shaped air baffle 532 are the same size, which is convenient for the flow of gas, the rubber pad 533 is bonded to the top end of the cavity of the screening plate 531, the inner fan-shaped air baffle 532 is bonded to the bottom end of the rubber pad 533 and moves along the inside of the cavity, the magnetic member one 534 is embedded and installed on one end face of the inner fan-shaped air baffle 532 close to the convex disc 51, the magnetic member one 534 and the magnetic member two 584 have opposite magnetic poles on the opposite surfaces (opposite sex attraction), the Teflon non-stick coating is sprayed inside the air inlet channel 6 to prevent dust from adhering to the inside of the air inlet channel 6.

[0052] When the magnetic member two 584 rotates through the fan-shaped connecting plate 583, the magnetic member two 584 rotates to one end face of the magnetic member two 584 at this time, and the magnetic member two 584 is attracted by the opposite sex attraction principle at this time, so that the magnetic member one 534 moves along the inside of the cavity of the screening plate 531, thereby driving the inner fan-shaped air baffle 532 to move, the inner fan-shaped air baffle 532 pulls the rubber pad 533 when it moves, at this time, the inner fan-shaped air baffle 532 and the positioning hole of the screening plate 531 are staggered, so that the negative pressure inside the air inlet channel 6 changes, forming a pulse type adsorption principle, and when the magnetic member two 584 and the magnetic member one 534 are separated, the inner fan-shaped air baffle 532 is reset under the action of the rubber pad 533.

[0053] In order to achieve the above-mentioned embodiment, how to make the shunt pipe 52 enter the output shaft of the driving motor 2, so that the gas can flow along the preset direction, the following solutions are provided, as shown in Figure 3 、 Figure 5 and Figure 8As shown, the filter structure 55 includes a mounting frame 551 fixedly installed on the air inlet end of the negative pressure fan 56 and connected with the pipeline 54, a vertical moving plate 552 vertically movably connected inside the mounting frame 551, reset members 553 installed between the top end and the bottom end of the vertical moving plate 552 and the inner wall of the mounting frame 551, a push rod 554 fixedly installed at the top end of the vertical moving plate 552, the push rod 554 being composed of a vertical column and a horizontal rod, the vertical column penetrating through the reset members 553 at the top end of the vertical moving plate 552 and the mounting frame 551, the horizontal rod of the push rod 554 being located inside the oval ring 582 and abutting against the inner wall of the oval ring 582, a circular corner being formed at the bottom end of the horizontal rod of the push rod 554, a screen 555 clamped and installed inside the vertical moving plate 552, the screen 555 being obliquely installed inside the vertical moving plate 552, and a groove 556 being formed at the bottom end of the screen 555 inside the vertical moving plate 552.

[0054] In use, since the distance between the inner wall of the oval ring 582 and the top end of the mounting frame 551 changes during rotation of the oval ring 582, the push rod 554 is driven to rise, the vertical moving plate 552 is driven to rise when the push rod 554 rises, one reset member 553 is stretched and one reset member 553 is compressed when the vertical moving plate 552 rises, and the vertical moving plate 552 moves up and down reciprocatingly inside the mounting frame 551 under the action of the reset members 553 during reciprocating rotation, thereby forming vibration, the screen 555 is vibrated at this time, and dust falls downward when the screen 555 is vibrated, so that the dust falls into the groove 556.

[0055] Working principle: the operator fixes the stainless steel casting to be polished on the mounting frame 5, sets the polishing parameters through the control system (which belongs to the prior art and will not be described in detail here), and starts the device, so that the driving motor 2 starts to rotate and drives the two polishing wheels 3 to rotate at high speed to polish the casting;

[0056] At the same time when the polishing starts, the negative pressure fan 56 starts to work, and the large amount of light stainless steel dust generated by the polishing is directly sucked into the air inlet channel 6 inside the polishing wheel 3 at the moment of splashing due to the suction of the negative pressure fan 56, and the dust is sequentially passed through the hollow output shaft of the driving motor 2, enters the negative pressure chamber of the shunt pipe 52 arranged axially inside the output shaft, and then is sent to the filtering structure 55 through the pipeline 54. The rotation of the polishing wheel 3 synchronously drives the rotation of the rotating disc 581 of the driving structure 58 and the fan-shaped connecting plate 583 and the magnetic suction member two 584 thereon, and when the magnetic suction member two 584 rotates to the position corresponding to the magnetic suction member one 534 in the shunt structure 53, a strong suction force is generated due to the opposite magnetic poles, the magnetic suction member one 534 is adsorbed, and the inner fan-shaped air baffle 532 connected therewith is moved in the cavity of the screening plate 531, and the displacement occurs by overcoming the elasticity of the rubber pad 533. At this time, the movement of the inner fan-shaped air baffle 532 makes the positioning holes thereon dislocated with the positioning holes on the screening plate 531, and partially or completely blocks the air flow channel, resulting in a sharp fluctuation of the negative pressure in the air inlet channel 6 at this moment, and a strong adsorption pulse is formed. This periodic pulse adsorption can more effectively capture the dust about to diffuse, and avoid the local airflow turbulence caused by continuous and stable adsorption.

[0057] The airflow containing dust enters the installation frame 551 of the filtering structure 55, and the dust is intercepted by the screen 555 obliquely arranged in the vertical moving plate 552 and adheres to the surface of the screen 555, and the purified clean gas enters the air inlet end of the negative pressure fan 56. The oval ring 582 of the driving structure 58 rotates with the rotating disc 581, and at this time, the horizontal rod of the push rod 554 is always in contact with the inner wall of the oval ring 582, and the rotation of the oval ring 582 will periodically lift or lower the push rod 554 due to the different radii of the major axis and the minor axis of the irregular contour of the inner wall of the oval ring 582. The up-and-down movement of the push rod 554 drives the vertical moving plate 552 to compress or stretch the restoring member 553 in the installation frame 551, and the vertical moving plate 552 makes continuous reciprocating vibration, and the vibration of the vertical moving plate 552 is directly transmitted to the screen 555, so that the dust particles adhering to the screen 555 are loosened and fall off, and fall into the groove 556 below to be collected, which effectively prevents the screen 555 from being blocked and ensures the persistent stability of the filtering efficiency.

[0058] The clean gas filtered and purified is pumped out from the air outlet end of the negative pressure fan 56, flows back to the positive pressure chamber of the shunt pipe 52 through another pipeline 54, and is discharged from the air outlet of the output shaft of the driving motor 2, and reenters the air inlet channel 6 of the polishing wheel 3. The gas performs backflushing on the inside of the air inlet channel 6, thereby preventing the air inlet channel 6 from being blocked due to dust.

[0059] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them.
