Description

Technical Field

[0001] This invention belongs to the field of polishing equipment technology, and particularly relates to a polishing equipment for special stainless steel plates. Background Technology

[0002] Special stainless steel plates refer to stainless steel plates with special properties. Through high alloy formulas and advanced metallurgical processes, they far exceed ordinary stainless steel in terms of corrosion resistance, strength, and toughness, and are widely used in extreme working conditions such as aerospace, nuclear power, and deep sea.

[0003] In the production of special stainless steel plates, belt sanders are usually used to polish them to improve their surface finish and eliminate surface defects. In order to meet the high polishing requirements of special stainless steel plates, it is necessary to use sanding belts with different abrasives and grits. However, existing belt sanders usually only have one sanding belt. During the polishing process, it is necessary to stop the machine to replace the sanding belt or to equip multiple belt sanders at the same time. Stopping the machine will affect the working efficiency and convenience of the belt sander, while equipping multiple belt sanders will increase production costs.

[0004] Therefore, it is necessary to improve the grinding devices in the existing technology. Summary of the Invention

Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the grinding equipment and are only for the purpose of describing the present invention and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] like Figure 5 , 6 As shown in Figure 12, a special stainless steel plate grinding device includes a hollow turntable 304 that is connected to a second power component 301. A connecting groove 310 is provided on the outer circumferential surface of the turntable 304 to connect its interior and exterior. An annular sanding belt 4 is provided on the turntable 304. The sanding belt 4 is divided into multiple grinding sections along its circumference. The length of each grinding section is consistent with the circumference of the turntable 304. One grinding section is circumferentially located on the outer circumference of the turntable 304, and the remaining grinding sections are stored inside the turntable 304 after passing through the connecting groove 310. A switching mechanism 5 is provided inside the turntable 304. The switching mechanism 5 is configured to switch between different grinding sections on the outer circumferential surface of the turntable 304.

[0021] The aforementioned grinding equipment is applicable to, but not limited to, grinding the surface of stainless steel plates. The second power component 301 is a motor, and the turntable 304 is fixedly connected to one end of the motor's drive shaft. The second power component 301 drives the turntable 304 to rotate, thereby grinding the special stainless steel plate through the abrasive belt 4 covering the outer circumference of the turntable 304. To meet different grinding requirements of stainless steel plates, the abrasive belt 4 is divided into multiple grinding sections, which are connected end-to-end to form a complete ring. Different grit sizes and types of abrasive are applied to the surface of each grinding section. A portion of the abrasive belt 4 circumferentially covers the outer circumference of the turntable 304, while the remaining portion is housed inside the turntable 304 and can be driven along a set path by the switching mechanism 5. When grinding stainless steel plates, the grinding section covering the outer periphery of the turntable 304 plays the main grinding role. When it is necessary to switch grinding sections, the turntable 304 stops rotating, and the switching mechanism 5 drives the sanding belt 4 to advance along the set path, thereby transferring one of the grinding sections stored inside the turntable 304 to the outer periphery of the turntable 304. This realizes the switching between different grinding sections. Each action of the switching mechanism 5 can drive the sanding belt 5 to advance along the set path by the length of one grinding section. By manually triggering the switching mechanism 5 multiple times, the desired grinding section can be switched. Through the above settings, the switching of different grinding sections of the grinding equipment is realized, which makes it convenient for the grinding equipment to grind stainless steel plates with different grinding requirements, improving the ease of use and grinding efficiency of the grinding equipment.

[0022] Further improvements include, for example Figure 6-8As shown, the turntable 304 has an opening on its front side, and a cover plate 305 is provided at the opening. The connecting groove 310 extends along the axial direction of the turntable 304, and one end is connected to the opening. The switching mechanism 5 includes multiple inner ring guide rollers 306 extending along the axial direction of the turntable 304 and multiple outer ring guide rollers 307 extending along the axial direction of the turntable 304. Each inner ring guide roller 306 and each outer ring guide roller 307 are circumferentially distributed at equal intervals around the axis of the turntable 304. The inner ring guide rollers 306 and the outer ring guide rollers 307 are staggered. The part of the sanding belt 4 located inside the turntable 304 passes back and forth between each outer ring guide roller 307 and each inner ring guide roller 306 in sequence. One of the inner ring guide rollers 306 and each outer ring guide roller 307 is a drive roller 508, which is driven to rotate by a third power member 507.

[0023] In the aforementioned grinding equipment, to facilitate the orderly storage of the sanding belt 4 inside the turntable 304, an inner guide roller 306 and an outer guide rail 307 are provided to guide the sanding belt 4 forward, so that the sanding belt 4 is folded and stored in an S-shape inside the turntable 304, thereby achieving orderly storage of the sanding belt 4 inside the turntable 304; at the same time, the sanding belt 4 is rolled and connected with the inner guide rail 306 and the outer guide roller 307, which can improve the smoothness of the movement of the sanding belt 4 when switching; when it is necessary to switch grinding sections, the third power component 507 drives the drive roller 508 to rotate, and then the drive roller 508 drives the sanding belt 4 forward, thereby completing the switching of the sanding belt 4.

[0024] Further improvements include, for example Figure 6 , 10 As shown in Figure 13, the drive roller 508 and the third power component 507 are both mounted on the sliding seat 504. The sliding seat 504 is radially slidably mounted inside the turntable 304. A fixed seat 501 is fixedly connected to the inner bottom wall of the turntable 304. The sliding seat 504 is connected to the fixed seat 501 through an elastic component. The elastic force of the elastic component acts on the sanding belt 4 through the drive roller 508, causing the sanding belt 4 to have a tendency to be tensioned. The sliding seat 504 is a magnetic seat. An electromagnet 502 is fixedly connected to the fixed seat 501. A pressure roller 509 is also elastically connected to the sliding seat 504. The pressure roller 509 is configured to press the sanding belt 4 and the drive roller 508 together. An anti-slip layer 401 is provided on the inner circumferential surface of the sanding belt 4.

[0025] The specific structure of the elastic element is as follows: Figure 10 and 13 As shown, the fixed seat 501 has a guide hole 503 extending radially along the turntable 304, and the sliding seat 504 is fixedly connected to a third guide rod 505. The third guide rod 505 is coaxially slidably engaged with the guide hole 503, and a first spring 506 is sleeved on the third guide rod 505, with its two ends respectively connected to the fixed seat 501 and the sliding seat 504.

[0026] Specifically, the third power component 507 includes a servo motor fixedly connected to the sliding seat 504. The drive end of the servo motor is fixedly connected to the drive gear. Both ends of the drive roller 508 are connected to the sliding seat 504 through bearings. One end of the drive roller 508 is provided with a driven gear that meshes with the drive gear. Thus, the servo motor can drive the drive roller 508 to rotate, thereby driving the sanding belt 4 to move forward along a set path through the drive roller 508 to achieve the switching of the sanding belt.

[0027] To ensure a firm connection between the sanding belt 401 and the outer circumference of the turntable 304 and prevent relative slippage during grinding, an anti-slip layer 401 is provided on the back of the sanding belt 401. However, during the switching of the sanding belt 401, the anti-slip layer hinders the forward movement of the sanding belt 401. To solve this problem, when switching the sanding belt 401, an electromagnet 502 can attract the sliding seat 504 to move radially away from the axis of the turntable 304. In this grinding equipment, the drive roller 508 is one of the inner guide rollers 306. Therefore, when the electromagnet 502 attracts the sliding seat 504 to move, the tension of the sanding belt 401 disappears, and the friction between the sanding belt 401 and the turntable 304 decreases. The drive roller 508 facilitates the movement of the sanding belt 4, thereby improving the ease of switching the sanding belt 4. In the above structure, the guide hole 503 and the third guide rod 505 slide together, which guides and supports the sliding of the sliding seat 504, thereby improving the stability and smoothness of the movement of the sliding seat 504. The first spring 506 sleeved on the third guide rod 505 can push the sliding seat 504 to reset after the sanding belt 4 is switched, thereby re-tensioning the sanding belt 4 by the drive roller 508. At the same time, the elasticity of the first spring 506 can also be used to maintain the stability of the tension of the sanding belt 4, thereby improving the stability of the sanding belt 4 during the operation of the grinding equipment and reducing the failure rate of the grinding equipment.

[0028] The clamping roller 509 and the drive roller 508 clamp the sanding belt 4 from both sides. The clamping roller 509 presses the sanding belt 4 and the drive roller 508 together, so that there is sufficient friction between them, which enables the drive roller 508 to effectively push the sanding belt 4 forward and prevent slippage between them, thereby improving the accuracy of sanding belt 4 switching.

[0029] The specific installation structure of the pressure roller 509 is as follows: Figure 13 As shown, the two ends of the pressing roller 509 are rotatably connected to the second guide sleeve 510, and the sliding seat 504 is fixedly connected to the fourth guide rod 511 extending radially along the drive roller 508. The fourth guide rod 511 is slidably engaged with the second guide sleeve 510, and the fourth guide rod 511 is fitted with the second spring 512, which is connected to the second guide sleeve 510 and the sliding seat 504 at its two ends respectively.

[0030] The fourth guide rod 511 and the second guide sleeve 510 cooperate with each other to support and guide the pressure roller 509. Then, under the tension of the second spring 512, the pressure roller 509 tends to move closer to the drive roller 508, so that the pressure roller 509 and the drive roller 508 clamp the sand belt 4 from both sides to increase the friction between the drive roller 508 and the sand belt 4 and prevent slippage between them. The ends of the fourth guide rod 511 and the third guide rod 505 away from the sliding seat 504 are both threaded with nuts, which can prevent the fourth guide rod 511 and the third guide rod 505 from falling off.

[0031] Further improvements include, for example Figure 7 and 8 As shown, multiple support rings 308 are provided on the side of the cover plate 305 near the turntable 304. The sum of the number of inner ring guide rollers 306 and outer ring guide rollers 307 is the same as the number of support rings 308, and they correspond one-to-one. One end of the inner ring guide rollers 306 and outer ring guide rollers 307 are fixedly connected to the inner bottom wall of the turntable 304, and the other end is inserted into the support rings 308. Guide grooves 309 extending radially are provided on the inner bottom wall of the turntable 304 and the cover plate 305. The sliding seat 504 and the second guide sleeve 510 are both slidably engaged with the guide grooves 309.

[0032] The inner guide roller 306 and the outer guide roller 307 each include a support shaft fixedly connected to the turntable 304 and a roller body connected to the support shaft via bearings. After the cover plate 304 is fixedly connected to the turntable 304 with screws, the ends of each support shaft are inserted into the interior of each support ring 308, thereby improving the stability of the support shaft and thus improving the firmness of the installation of the inner guide roller 306 and the outer guide roller 307. The guide groove 309 can limit and guide the sliding seat 504 and the second guide sleeve 510, thereby improving the stability of the sliding of the drive roller 508 and the pressure roller 509.

[0033] Further improvements include, for example Figure 1 and 2 As shown, the second power component 301 is mounted on the moving mechanism, which includes two parallel tracks 101. A moving trolley 102 is slidably mounted on the tracks 101. A column 103 is fixedly connected to the moving trolley 102. A horizontally extending first guide rod 107 and a first power component 104 are fixedly connected between the top ends of the two columns 103. A translation seat 105, which is driven by the first power component 104, is slidably mounted on the first guide rod 107. A vertically extending first guide sleeve 108 is fixedly connected to the translation seat 105. A second guide rod 109 is slidably mounted coaxially on the inner side of the first guide sleeve 108. A lifting seat 110 is fixedly connected to the bottom end of the second guide rod 109. A cylinder 106, which is driven by the lifting seat 110, is fixedly connected to the first guide sleeve 108. The second power component 301 is fixedly connected to the lifting seat 110.

[0034] The mobile trolley 102 has a drive wheel and a motor that are rolledly connected to the track 101. The motor is connected to the drive wheel, allowing the mobile trolley 102 to move along the track 101. The first power component 104 includes a motor and a lead screw. The lead screw is threadedly connected to the translation seat 105. The motor drives the lead screw to rotate, which in turn drives the translation seat 105 to slide the first guide rod 107. The first guide rod 107 and the track 101 extend horizontally and are perpendicular to each other, allowing the turntable 304 to move freely in the horizontal direction. Then, under the mutual limiting action of the first guide sleeve 108 and the second guide rod 109, the cylinder 106 drives the lifting seat 110 to rise and fall, thereby realizing the lifting and falling of the turntable 304. This allows the turntable 304 to move freely in three-dimensional space. The rotation of the turntable 304 drives the sanding belt 4 to grind the stainless steel plate, improving the ease of use of the grinding equipment.

[0035] Further improvements include, for example Figure 3 and 4 As shown, a protective cover 204 is fixedly connected to the lifting base 110. The protective cover 204 partially surrounds and covers the turntable 304. An openable and closable baffle 205 is rotatably mounted on the side of the protective cover 204 away from the lifting base 110. A dust removal mechanism 2, which communicates with the interior of the protective cover 204, is fixedly connected to the first guide sleeve 108. The protective cover 204 is fixed to the lifting base 110 by bolts and nuts. The protective cover 204 covers the upper part of the turntable 304, thereby blocking the splashes during the grinding process and improving the safety of the grinding equipment. The openable and closable baffle 205 facilitates maintenance of the turntable 304 inside.

[0036] The specific structure of dust removal mechanism 2 is as follows: Figure 2-4 As shown, the system includes a dust collector 202 with an internal filter element, an air pump 201 at the air outlet of the dust collector 202, and an air inlet connected to a protective cover 204 via a hose 203. The second power unit 301 includes a tubular drive shaft 302 fixedly connected to a turntable 304. The drive shaft 302 and the turntable 304 are internally interconnected. An opening 303 is provided on the side of the drive shaft 302. A vacuum box 206 is fixedly connected to the lifting seat 110. The vacuum box 206 has a through hole 207 for the drive shaft 302 to pass through. The hose 203 is interconnected with the vacuum box 206.

[0037] The dust collection box 202 is equipped with an activated carbon filter to filter out particulate matter in the air. Air is drawn into the dust collection box 202 by the air pump 201, which is then purified to reduce the amount of splashes and dust during the grinding process and improve the environmental performance of the grinding equipment. The hollow drive shaft 302 connects the dust collection box 202 and the turntable 304. The through hole 207 and the drive shaft 302 are sealed by a rubber ring. When the air pump 201 draws air, the air inside the turntable 304 first enters the vacuum box 206 through the opening 303, and then enters the dust collection box 202 through the hose 203. This allows impurities that fall off the sanding belt 4 during the switching process to be removed, thus cleaning the sanding belt 4.

[0038] Further improvements include, for example Figure 9 and 11 As shown, the dust removal mechanism 2 also includes a base plate 311 fixedly connected to the inner bottom wall of the turntable 304. The base plate 311 is a perforated plate, and multiple cleaning brushes 6 are detachably connected to the base plate 311. The cleaning brushes 6 extend along the axial direction of the turntable 304 and are arranged close to the inner ring guide roller 306. When the sand belt 4 passes through the inner ring guide roller 306, the cleaning brushes 6 clean the front side of the sand belt 4.

[0039] Specifically, the base plate 311 has an insertion groove 312 extending axially along the turntable 304. The cleaning brush 6 has an insertion strip 601 that matches the insertion groove 312, which facilitates the replacement of the cleaning brush 6. Under the support of the base plate 311, the cleaning brush 6 abuts against the outer wall of the sanding belt 4. During the switching of the sanding belt 4, the cleaning brush 6 can remove some of the impurities adhering to the sanding belt 4. At the same time, in conjunction with the dust removal mechanism, the removed impurities are sucked out to the outside of the turntable 304, which can achieve the cleaning effect of the sanding belt 4 and improve the sanding effect of the sanding belt 4. At the same time, the air pump 201 can also promote the air flow inside the turntable 304 to achieve the cooling effect of the turntable 304, thereby achieving the cooling effect of the sanding belt 4, slowing down the aging of the sanding belt 4, extending its service life, and reducing the failure rate of the sanding equipment.
