Description

Technical Field

[0001] This invention relates to the field of polishing wheel production, and more specifically, to polishing wheel production processes and testing equipment. Background Technology

[0002] Limiting polishing wheels are used for plating polishing. Through different polishing methods, various stainless steel sheets, pipes, bars, and profiles can achieve different levels of surface finish, greatly improving the appearance of stainless steel. Traditional polishing wheel manufacturing processes mainly include material selection, abrasive preparation, binder mixing, forming, hardening, and post-treatment. However, these steps present some problems. The surface roughness of the formed polishing wheel is high, resulting in a rough grinding surface when grinding components, making it unsuitable for processing delicate workpieces and reducing the applicability of the polishing wheel. Therefore, it is necessary to develop polishing wheel manufacturing processes and testing equipment.

[0003] The Chinese invention patent (application number: CN202310229362.7) discloses a "polishing wheel and its manufacturing process," the specification of which reveals that, for example, in the invention patent entitled "A Resin Polishing Wheel Production Formula and Manufacturing Process," published in CN112428163A, a polishing wheel is designed that includes any one or any combination of abrasives such as green silicon carbide, black silicon carbide, single-crystal corundum, brown corundum, white corundum, zirconium corundum, black corundum, microcrystalline corundum, and diamond. Similarly, abrasives are used in the manufacturing process of the polishing wheel, thereby increasing its roughness. Consequently, during subsequent polishing of the denture, the surface of the denture is relatively rough, reducing the practicality of the polishing wheel. The aforementioned patents can corroborate the defects of the existing technology.

[0004] Therefore, we have made improvements and proposed a polishing wheel production process and testing equipment. Summary of the Invention

[0008] As a preferred technical solution of this application, the substrate in S1 consists of 9 kg of nylon fiber, 10 kg of primary green silicon carbide, 6 kg of epoxy resin, 4 kg of low molecular weight 650 polyamide resin, and 3 kg of calcium stearate.

[0009] As a preferred technical solution of this application, the stirring temperature in step S2 is 35-40℃ and the stirring time is 10-20 minutes.

[0010] As a preferred technical solution of this application, in step S4, burrs on the edges and corners of the polishing wheel are cleaned to make the surface of the polishing wheel smooth.

[0011] As a preferred technical solution of this application, the hardness and wear resistance of the polishing wheel are detected in step S5.

[0012] As a preferred technical solution of this application, in step S6, a label is affixed to the box to indicate the name, specifications and quantity of the polishing wheels, and the packaged polishing wheels are stored in a dry, ventilated and moisture-proof place.

[0013] A polishing wheel inspection device includes a base, a positioning seat fixedly mounted on the top of the base, and an inspection mechanism above the positioning seat. The inspection mechanism includes a disc, and a first motor is connected to the bottom of the disc via a support block. A threaded rod is fixedly connected to the shaft of the first motor. Threaded sleeves are threaded on both sides of the surface of the threaded rod. A connecting rod is fixedly connected to the bottom of the threaded sleeves. An inspection shell is connected to the bottom of the connecting rod via a rotating shaft. The bottoms of the two inspection shells are rotatably connected via a rotating shaft.

[0014] As a preferred technical solution of this application, the top of the disc is provided with an adjustment mechanism, the adjustment mechanism includes a vertical rod, the top of the base is fixedly connected to a U-shaped plate, the top of the U-shaped plate is rotatably connected to a driven gear, the top of the vertical rod passes through the U-shaped plate and the driven gear in sequence, the top of the U-shaped plate is connected to a second motor by screws, the top of the second motor shaft is fixedly connected to a driving gear, the left side of the driving gear meshes with the driven gear, and a counterweight mechanism is installed on the top of the disc.

[0015] As a preferred technical solution of this application, the counterweight mechanism includes a fixed tube, the bottom of which is fixedly connected to the top of the disc, a first spring fixedly connected to the inner wall of the fixed tube, a movable rod fixedly connected to one end of the first spring, a counterweight ring fixedly connected to the end of the movable rod away from the first spring, electromagnets fixedly connected to both the front and rear sides of the top of the counterweight ring, short horizontal grooves, oblique grooves and long horizontal grooves respectively opened on the surface of the fixed tube, and a guide rod fixedly connected to the top of the movable rod, the top of the guide rod extending through to the top of the short horizontal groove.

[0016] As a preferred technical solution of this application, both sides of the positioning seat are provided with a delayed return dust collection mechanism, which is used to absorb the dust generated when the polishing wheel is being tested.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the scheme of this application: 1. In order to solve the problem that the surface roughness of the existing polishing wheel is large, which makes the polishing surface rough when grinding components, and cannot process fine workpieces, thus reducing the applicability of the polishing wheel, this application stirs and mixes the substrate so that the substrate can be uniformly fused together. During the molding process, the substrate is pressurized to make the mixture tightly bonded, thereby achieving a fine polishing wheel surface and improving the applicability of the polishing wheel. 2. The detection mechanism enables the adjustment of the detection shell shape. When the detection shell is conical, the hardness of the polishing wheel can be detected. When the detection shell changes shape, the wear resistance of the polishing wheel can be detected, thus solving the problem that a single device in the prior art cannot simultaneously detect the hardness and wear resistance of the polishing wheel. 3. The adjustment mechanism enables the rotation of the detection shell. When the detection shell is transformed into a grinding mode, it facilitates the rotation of the detection shell to grind the polishing wheel. In conjunction with the counterweight mechanism, gravity is applied to the disc and the detection shell during the grinding process, which can better test the wear resistance of the polishing wheel, improve the testing efficiency, and solve the problem of low wear resistance testing efficiency. 4. The delayed return dust collection mechanism enables the detection plate to return to its original position. The position of the detection plate is measured by the scale groove, and the grinding time can be controlled during the wear detection process, thereby better detecting the wear resistance of the polishing wheel. The detection plate and the adjustment mechanism can be used to raise and lower the detection shell, and adjust the height of the detection shell to better detect the hardness of the grinding wheel, thus solving the problem of inconvenience in detecting the hardness of the grinding wheel.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] As described in the background art, the surface roughness of the shaped polishing wheel is large, which makes the polishing surface relatively rough when grinding components, making it impossible to process fine workpieces and reducing the applicability of the polishing wheel.

[0022] To solve this technical problem, the present invention provides a polishing wheel manufacturing process and testing equipment, which are applied to polishing wheel production.

[0023] For details, please refer to Figure 1 The polishing wheel manufacturing process includes the following steps: S1. Selecting the substrate: Nylon fiber, Grade I green silicon carbide, epoxy resin, low molecular weight 650 polyamide resin, and calcium stearate; S2. Mixing: Add the substrates from S1 to a mixer and mix while adding; S3. Molding: Pour the mixture into a mold and shape it, then perform a hardening treatment at a molding pressure of 450-500 kPa; S4. Cleaning: Remove the polishing wheel and allow it to cool. After it reaches room temperature, clean and trim the shaped polishing wheel; S5. Inspection: Place the polishing wheel on an inspection device for testing; S6.

[0024] In step S1, the base material consists of 9 kg of nylon fiber, 10 kg of grade 1 green silicon carbide, 6 kg of epoxy resin, 4 kg of low molecular weight 650 polyamide resin, and 3 kg of calcium stearate. In step S2, the stirring temperature is 35-40℃ and the stirring time is 10-20 minutes.

In step S6, the box is labeled with the name, specifications, and quantity of the polishing wheel, and the packaged polishing wheel is stored in a dry, ventilated, and moisture-proof place.

[0025] The polishing wheel production process provided by this invention involves stirring and mixing the substrate to ensure uniform fusion, and applying pressure to the substrate during the molding process to ensure tight bonding within the mixture, thereby achieving a fine surface finish on the polishing wheel and improving its applicability.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1 Please refer to Figure 2 , Figure 3 and Figure 4 The polishing wheel inspection equipment includes a base 1, a positioning seat 2 fixedly installed on the top of the base 1, and an inspection mechanism 3 set above the positioning seat 2. The inspection mechanism 3 includes a disc 31, a first motor 32 connected to the bottom of the disc 31 via a support block, a threaded rod 33 fixedly connected to the shaft of the first motor 32, threaded sleeves 34 threaded on both sides of the surface of the threaded rod 33, a connecting rod 35 fixedly connected to the bottom of the threaded sleeves 34, and an inspection shell 30 connected to the bottom of the connecting rod 35 via a rotating shaft. The bottoms of the two inspection shells 30 are rotatably connected by a rotating shaft.

[0030] The bottom of the detection shell 30 extends into the inner cavity of the positioning seat 2. The inner cavity of the positioning seat 2 contains the polishing wheel body. A bolt is installed through the surface of the positioning seat 2. One end of the bolt passes through the inner cavity of the positioning seat 2 and contacts the polishing wheel body. The bolt is threadedly connected to the positioning seat 2. A sealing ring is fitted on the surface of the disc 31. The threads on both sides of the surface of the threaded rod 33 rotate in opposite directions.

[0031] By setting bolts, the polishing wheel placed in the inner cavity of the positioning seat 2 can be positioned to prevent the polishing wheel from shifting during inspection. By setting a sealing ring, when the grinding inspection is performed, the disc 31 extends into the inner cavity of the positioning seat 2, and the sealing ring seals the disc 31 and the positioning seat 2, thereby improving the sealing performance.

[0032] Example 2 The polishing wheel and testing equipment provided in Example 1 have been further optimized, specifically, as follows: Figure 3 As shown, an adjustment mechanism 4 is provided on the top of the disc 31. The adjustment mechanism 4 includes a vertical rod 40. A U-shaped plate 41 is fixedly connected to the top of the base 1. A driven gear 42 is rotatably connected to the top of the U-shaped plate 41. The top of the vertical rod 40 passes through the U-shaped plate 41 and the driven gear 42 in sequence. A second motor 43 is connected to the top of the U-shaped plate 41 by screws. A driving gear 44 is fixedly connected to the top of the shaft of the second motor 43. The left side of the driving gear 44 meshes with the driven gear 42. A counterweight mechanism 5 is installed on the top of the disc 31.

[0033] The vertical rod 40 is movably connected to the U-shaped plate 41 and the driven gear 42 respectively. By setting the driven gear 42, the vertical rod 40 can be rotated during grinding and testing, and the vertical rod 40 can be guided during hardness testing to facilitate the vertical movement of the vertical rod 40.

[0034] Example 3 The polishing wheel and testing equipment provided in Example 1 or 2 are further optimized, specifically, as follows: Figure 5As shown, the counterweight mechanism 5 includes a fixed tube 50, the bottom of which is fixedly connected to the top of the disc 31. A first spring 51 is fixedly connected to the inner wall of the fixed tube 50. A movable rod 52 is fixedly connected to one end of the first spring 51. A counterweight ring 53 is fixedly connected to the end of the movable rod 52 away from the first spring 51. Electromagnets 54 are fixedly connected to both the front and rear sides of the top of the counterweight ring 53. A short horizontal groove 55, an inclined groove 56, and a long horizontal groove 57 are respectively opened on the surface of the fixed tube 50. A guide rod 58 is fixedly connected to the top of the movable rod 52. The top of the guide rod 58 extends through to the top of the short horizontal groove 55.

[0035] After the two counterweight rings 53 come into contact, they form a ring. By setting the first spring 51, a pulling force is applied to the movable rod 52, which facilitates the rapid return of the counterweight rings 53. By setting the short transverse groove 55, the inclined groove 56 and the long transverse groove 57, the guide rod 58 can be guided, which facilitates the movement of the guide rod 58. The guide rod 58 can drive the movable rod 52 and the counterweight rings 53 to move. The counterweight rings 53 can also rotate during the movement.

[0036] Furthermore, such as Figure 6 , Figure 7 and Figure 8 As shown, both sides of the positioning seat 2 are provided with delayed return dust collection mechanisms 6. The delayed return dust collection mechanisms 6 are used to absorb the dust generated when the polishing wheel is being tested. The delayed return dust collection mechanism 6 includes a housing 60. The bottom of the housing 60 is fixedly connected to the base 1. The top of the housing 60 is connected to a dust collection hood 61. One side of the dust collection hood 61 extends into the inner cavity of the positioning seat 2. A partition 62 is fixedly connected to the inner cavity of the housing 60. A collection box 63 is placed on the top of the partition 62. A ventilation mesh 64 is inlaid on the inner wall of the collection box 63 and the surface of the partition 62. A piston plate 65 is movably connected to the inner cavity of the housing 60. A pull rod 66 is fixedly connected to the left side of the piston plate 65.

[0037] One side of the housing 60 is fixedly connected to the positioning seat 2. The front side of the collection box 63 extends through to the front side of the housing 60. A handle is connected to the front side of the collection box 63 by screws. The handle facilitates the movement of the collection box 63 and its disassembly. A sealing sleeve is provided between the surface of the collection box 63 and the housing 60 to seal the connection between the collection box 63 and the housing 60, thereby improving the sealing performance. The collection box 63 is used to collect dust absorbed from inside the positioning seat 2. A ventilation net 64 is provided so that the gas above the collection box 63 enters below the partition 62, facilitating gas flow. The top of the piston plate 65 contacts the partition 62, and the bottom of the piston plate 65 contacts the base 1.

[0038] Furthermore, such as Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, one end of the pull rod 66 extends through to the outside of the box 60 and is fixedly connected to the detection plate 67. A second spring 68 is sleeved on the surface of the pull rod 66. Threaded protrusions 69 are fixedly connected to the opposite side of the two detection plates 67. The detection plates 67 engage with the counterweight ring 53 through the threaded protrusions 69. An air hole 610 is opened on the top of the disc 31. Graduation grooves 611 are opened on both sides of the top of the base 1. The graduation grooves 611 are used in conjunction with the detection plates 67.

[0039] One end of the second spring 68 is fixedly connected to the piston plate 65, and the other end of the second spring 68 is fixedly connected to the housing 60. The pull rod 66 is movably connected to the housing 60. By setting the second spring 68, tension is generated on the piston plate 65, which facilitates the return of the piston plate 65. By setting the air hole 610, external gas can enter the bottom of the disc 31 through the air hole 610, which facilitates the circulation of gas between the inside of the base 1 and the outside.

[0040] The process of using the polishing wheel inspection device provided by this invention is as follows: S1. Hardness detection: By controlling the operation of the second motor 43, the driving gear 44 is rotated, which in turn drives the driven gear 42 to rotate. The driven gear 42 drives the vertical rod 40 to rotate, which in turn drives the disc 31, the fixed tube 50, the movable rod 52, and the counterweight ring 53 to rotate. The counterweight ring 53 engages with the threaded protrusion, causing the counterweight ring 53 to move upward, which in turn drives the bottom detection shell 30 to move upward. When the two detection shells 30 move to the specified height, opposite currents are applied to the electromagnets 54, causing the two electromagnets 54 to repel each other and the two counterweight rings 53 to move away from each other. The counterweight rings 53 push the detection plate 67 to move, which in turn drives the pull rod 66 and the piston plate 65 to move. The piston plate 65 compresses the second spring 68, and then the same current is applied to the two electromagnets 54, causing the two counterweight rings 53 to quickly attract each other. At this time, the detection plate 67 will return to its original position after a delay, and the detection shell 30 will fall downward. Finally, the detection shell 30 will hit the polishing wheel, thereby detecting the hardness of the polishing wheel. S2. Wear Resistance Testing: By controlling the operation of the first motor 32, the threaded rod 33 is rotated. The threaded rod 33 drives the threaded sleeve 34 to move. The two threaded sleeves 34 drive the two connecting rods 35 to move away from each other. The connecting rods 35 drive the detection shell 30 to rotate, making the two sides of the detection shell 30 parallel to the top surface of the polishing wheel. By controlling the detection shell 30 to move downward and contact the top surface of the polishing wheel, opposite currents are passed to the two electromagnets 54, causing the two electromagnets 54 to drive the counterweight ring 53 to move away from each other. During the movement, the counterweight ring 53 drives the movable rod 52 and the guide rod 58 to rotate. The guide rod 58 moves into the inclined groove 56. When the guide rod 58 moves into the long horizontal groove 57, the two counterweight rings 53 rotate to a horizontal position, with the bottom surface of the counterweight rings 53 parallel to the disk 31. The current is increased through the current regulator on the electromagnet 54, increasing the distance between the two counterweight rings 53. The movement distance of the detection plate 67 is measured through the scale groove 611. Then, the same current is applied to the two electromagnets 54, causing them to quickly attract each other, moving the counterweight rings 53, the movable rod 52, and the guide rod 58. When the guide rod 58 approaches... When the inclined chute 56 stops moving, the bottom surfaces of the two counterweight rings 53 remain parallel to the disk 31, and the counterweight rings 53 are separated from the detection plate 67. The second motor 43 is controlled to rotate the drive gear 44, which in turn rotates the driven gear 42, the vertical rod 40, the disk 31, and the detection shell 30. The rotating detection shell 30 contacts and rubs against the polishing wheel for detection. The second spring 68 pushes the piston plate 65 to slowly return to its original position. At this time, because the inside of the housing 60 is sealed, the gas at the top of the disk 31 enters the positioning seat 2 through the vent 610. Because the vent 610 has a very small diameter, the gas... The entry speed is very slow. During the friction between the detection shell 30 and the polishing wheel, dust will be generated. The dust floating in the air will pass through the dust suction hood 61, the collection box 63 and the ventilation net 64 in sequence, and finally enter the bottom of the inner cavity of the box 60. After the piston plate 65 drives the pull rod 66 and the detection plate 67 to return to their original positions, the threaded protrusion 69 on the surface of the detection plate 67 contacts the counterweight ring 53 to inhibit the rotation of the counterweight ring 53. At the same time, the second motor 43 is controlled to stop running. Then the wear of the polishing wheel is observed. By driving the detection plate 67 to different positions, the different wear resistance of the polishing wheel can be obtained, and thus the wear resistance of the polishing wheel can be detected.
