Technical Field

[0001] The invention relates to the technical field of screw grinding, in particular to a grinding device for processing stainless steel screws. Background Art

[0002] Stainless steel screws need to go through multiple processes during the manufacturing process, among which grinding is an indispensable part. The grinding process is mainly used to remove burrs, oxide layers and tiny surface defects on the surface of the screws, making the surface of the screws smoother, thereby improving the connection performance and appearance quality of the screws. However, the existing grinding equipment is usually inefficient in practical applications. Due to the high hardness of stainless steel materials, the grinding process takes a long time, and the design of the equipment itself may not provide sufficient grinding force and stability, resulting in low grinding efficiency, poor grinding quality, and poor thread fit; and the grinding equipment is prone to generate a large amount of dust and debris during high-speed operation.

[0017] The present invention provides a grinding device for stainless steel screw processing, which has the following beneficial effects:

[0018] 1. The grinding device for stainless steel screw processing drives the grinding disc to move rightward to the inside of the protective sleeve through an electric slide, and performs semi-closed grinding on the stainless steel screws inside the protective sleeve, which can prevent dust from flying around. At the same time, combined with the shielding of the grinding disc itself on the left side of the opening and the close shielding of the right wall inside the box facing another opening opened on the right side of the protective sleeve surface, the range of dust splashing inside the box is reduced.

[0019] 2. The grinding device for stainless steel screw processing can conveniently intercept and collect most of the dust inside the bottom bucket, and surround the stainless steel screws with a protective sleeve to achieve a shielding effect. It can not only intercept the dust generated during grinding into the bottom bucket, but also shield the splashes generated during grinding inside the protective sleeve, thereby avoiding the impact of splashing foreign matter on the operator or the surrounding working environment and protecting the operator's work safety.

[0020] 3. The grinding device for stainless steel screw processing can synchronously drive the fan blades to rotate around the central axis of the three-clamp grip cylinder while the three-clamp grip cylinder is driven to rotate by the DC motor, thereby generating a downward airflow inside the protective sleeve, so that the dust generated during the grinding of the stainless steel screws can be blown vertically downward, and the rounded corner design at the contact part between the cross wall band and the inner wall of the protective sleeve can increase the wall thickness of the frame near the opening while eliminating the problem of right-angle blocking of the airflow caused by the cross wall band, prevent the airflow blown vertically downward along the side of the inner wall of the protective sleeve from being blocked and intercepted, thereby preventing the airflow near the opening from being turbulent, reducing the situation where the airflow near the opening blows dust to the outside of the opening, and ensuring that most of the dust can be blown into the bottom hopper by the airflow and collected.

[0021] 4. The grinding device for stainless steel screw processing uses a guide plate to buffer and intercept the dust blown into the bottom hopper, so that the dust is guided by the guide plate to the bottom of the guide plate, and enters the bottom hopper through the filter to be stored. At the same time, the guide plate is used as an interception structure shielding the filter directly above the filter to avoid the airflow being blown directly to the bottom of the hopper, and the dust collected in the hopper is blown out to prevent the dust from flowing back or escaping, thereby ensuring the one-way collection and storage function of the hopper for dust.

[0022] 5. The grinding device for stainless steel screw processing can magnetically position the bottom of the stainless steel screw through the electromagnetic rod during grinding, so that the top and bottom of the stainless steel screw are always in the rotational motion of the same axis. The metal dust generated during grinding can be separately adsorbed and collected on the surface of the electromagnetic rod in real time, which can not only reduce the hidden dangers of metal dust splashing or lasing, but also reduce the dispersion range of metal dust inside the box. Combined with the surrounding shielding and interception of dust by the protective sleeve and the one-way collection of dust by the bottom bucket, the pollution of dust to the surrounding working environment during grinding of stainless steel screws can be comprehensively reduced, and the subsequent maintenance and cleaning work of the grinding device can be reduced.

[0023] 6. The grinding device for stainless steel screw processing can maintain the magnetic attraction and positioning effect of the electromagnetic rod on the bottom of the stainless steel screw after the surface of the stainless steel screw is polished, and the three-clamp cylinder is activated to loosen the clamp to release the top of the stainless steel screw. Then, as the clamp is slowly opened, the electric telescopic push rod is gradually activated to extend and press against the middle of the top of the stainless steel screw. At the same time, during this period, the electric cylinder is activated to drive the long rod shaft to descend, and the top of the stainless steel screw is lowered and positioned to the position in contact with the grinding disk in coordination with the extension action of the electric telescopic push rod. In this way, the top of the stainless steel screw can be polished by the grinding disk, so that the top of the stainless steel screw clamped in the clamp can also be polished in place, eliminating the grinding dead angle of the stainless steel screw, and realizing comprehensive grinding of the stainless steel screw by the grinding device.

[0024] 7. The grinding device for processing stainless steel screws activates the hydraulic cylinder and the electric cylinder to move the stainless steel screw upward by the height of half the diameter of the grinding disk and moves the electromagnetic rod downward by the height of half the diameter of the grinding disk, so that the electric slide can drive the grinding disk at the right end of the grinding motor to continue to move horizontally to the right without being blocked by the stainless steel screw, so that the grinding disk passes the station where it contacts and grinds the stainless steel screw, and the grinding brush is moved to the grinding station. The grinding motor drives the grinding brush on the extension shaft to polish the surface of the stainless steel screw, so that the dust and fine burrs remaining on the surface of the stainless steel screw are thoroughly polished and removed.

[0025] 8. The grinding device for stainless steel screw processing can supplement and grind the dead corners of the oxide layer remaining on the surface of the stainless steel screw, remove these oxide layers, improve the smoothness of the screw surface, reduce the surface roughness, remove minor surface defects and residual contaminants, and improve the corrosion resistance of the stainless steel screw. At the same time, through this secondary fine grinding method, it can repair slight scratches or damage on the surface of the stainless steel screw, repair these defects, and for the threaded part of the stainless steel screw, it can remove irregularities in the manufacturing process, ensure that the thread fits more tightly and accurately, improve the thread fit of the stainless steel screw, and improve the overall quality of the product.

[0026] 9. The grinding device for stainless steel screw processing can utilize the contact and rotation of the grinding disc with the surface of the stainless steel screw for grinding. At the same time, the DC motor drives the three-clamp cylinder to rotate, thereby driving the stainless steel screw to rotate around the axis of the three-clamp cylinder and inside the protective sleeve, thereby increasing the grinding contact area of ​​the grinding disc with the stainless steel screw per unit time, improving the grinding surface, and improving the grinding efficiency.

[0046] The lifting assembly 7 has an electromagnetic rod 9 that magnetically attracts the bottom of the stainless steel screw, and a clamping unit 11 installed on the top of the lifting assembly 7. The electromagnetic rod 9 is installed in the middle of the inner side of the protective sleeve 6 through the lifting assembly 7. An electric telescopic push rod 13 is installed in the middle of the bottom of the three-clamp gripping cylinder 10. The telescopic end of the electric telescopic push rod 13 contacts the middle part of the top of the stainless steel screw.

[0047] A through opening 61 is opened through the surface of the protective sleeve 6, and the through opening 61 is opened along the axial direction of the polishing piece 8. A cross wall band 62 is fixedly installed on the inner wall of the protective sleeve 6, and the cross wall band 62 is installed around the through opening 61, and the connection between the through opening 61 and the inner wall of the protective sleeve 6 is chamfered.

[0048] The lifting assembly 7 includes an electric cylinder 71, which is fixedly mounted on the inner bottom plate of the box body 1 and away from one end of the stand. A bottom bucket 72 is mounted in the middle of the top of the electric cylinder 71, and the bottom bucket 72 is docked with the protective sleeve 6. A spherical shell 73 is installed around the electric cylinder 71 to provide shielding protection for the electric cylinder 71 and prevent dust accumulation.

[0049] A guide plate 74 is installed in the middle of the inner side of the bottom hopper 72 , and a filter screen 75 is installed in the middle of the inner side of the bottom hopper 72 for filtering and collecting dust generated by grinding inside the bottom hopper 72 . The filter screen 75 is installed directly below the guide plate 74 , and the diameter of the guide plate 74 is larger than the diameter of the filter screen 75 .

[0050] The polishing part 8 includes an extended shaft 81, which is bolted to the grinding disc 3. The extended shaft 81 is connected to the output end of the grinding motor 2 through a second coupling. A grinding brush 82 is bolted to the surface of the extended shaft 81 at one end close to the grinding disc 3, and a paint brush 83 is installed on the left side of the grinding brush 82, and the paint brush 83 is bolted to the extended shaft 81.

[0051] An annular transfer tube 84 is rotatably installed on the surface of the extended shaft 81, and a pump 85 is fixedly installed on one side of the electric slide of the grinding motor 2. The output end of the pump 85 is connected to the annular transfer tube 84, and the pump 85 is connected to the inside of the paint brush 83 through the annular transfer tube 84 and the extended shaft 81.

[0052] A paint box 86 is installed on the left side of the pump 85. The paint box 86 contains liquid paint. The paint box 86 is installed in an interlocking manner with the electric slide. The output end of the paint box 86 is connected to the input end of the pump 85 for conveying liquid paint to the paint brush 83.

[0053] When in use, the stainless steel screw is clamped and fixed by the three-clamp gripping cylinder 10, and then the electric cylinder 71 is activated to drive the long rod shaft 712 to rise, so that the top of the electromagnetic rod 9 is against the bottom middle position of the stainless steel screw, and then the electric slide, grinding motor 2 and DC motor 5 are activated at the same time. The electric slide drives the grinding motor 2 and the grinding disc 3 on the polishing piece 8 to move along the axial direction of the extended shaft 81, so that the grinding disc 3 contacts the surface of the stainless steel screw, and driven by the reciprocating translation of the electric slide, the grinding disc 3 is driven to perform reciprocating translation contact grinding on the surface of the stainless steel screw, and the grinding motor 2 is used to drive the grinding disc 3 at the right end of the extended shaft 81 to rotate, and the grinding The disc 3 is in contact with the surface of the stainless steel screw for rotation and grinding, and at the same time, the DC motor 5 drives the three-clamp gripping cylinder 10 to rotate, so as to drive the stainless steel screw to rotate around the axis of the three-clamp gripping cylinder 10 and the inner side of the protective sleeve 6, thereby increasing the grinding contact area of ​​the grinding disc 3 with the stainless steel screw per unit time, improving the grinding surface, and improving the grinding efficiency. After the surface with the stainless steel screw is polished, the three-clamp gripping cylinder 10 can be activated to separate the three grippings to remove the polished stainless steel screw, and then the next stainless steel screw to be polished can be re-clamped and installed, and the operation is cyclically carried out to realize the continuous grinding operation of the stainless steel screw by the grinding device.

[0054] During the grinding of stainless steel screws, the grinding disc 3 is driven by the electric slide to move horizontally to the right into the protective sleeve 6, and the stainless steel screws are semi-closedly ground inside the protective sleeve 6, which can prevent dust from flying around. At the same time, combined with the shielding of the grinding disc 3 itself on the left side of the opening 61, and the close shielding of the right wall inside the box body 1 facing another opening 61 opened on the right side of the surface of the protective sleeve 6, the range of dust splashing inside the box body 1 is reduced, and most of the dust is conveniently intercepted and collected inside the bottom hopper 72, and the stainless steel screws are surrounded and wrapped by the protective sleeve 6, which has a shielding effect, not only can the dust generated during grinding be intercepted into the bottom hopper 72, but also the splashing generated during grinding can be shielded inside the protective sleeve 6, avoiding the impact of foreign matter splashing on the operator or the surrounding working environment, and protecting the operator's work safety.

[0055] While the three-clamp gripping cylinder 10 is driven to rotate by the DC motor 5, the fan blades 12 can be synchronously driven to rotate around the central axis of the three-clamp gripping cylinder 10, thereby generating a downward airflow on the inner side of the protective sleeve 6, thereby blowing the dust generated during the grinding of the stainless steel screws vertically downward, and the rounded corner design at the contact point between the cross wall band 62 and the inner wall of the protective sleeve 6 increases the wall thickness of the frame near the opening 61 while eliminating the problem of right-angle blocking of the airflow caused by the cross wall band 62, preventing the airflow blown vertically downward along the inner wall side of the protective sleeve 6 from being blocked and intercepted, thereby preventing the airflow near the opening 61 from being turbulent, reducing the situation where the airflow near the opening 61 blows dust to the outside of the opening 61, and ensuring that most of the dust can be blown into the bottom hopper 72 by the airflow and collected.

[0056] The dust blown into the bottom hopper 72 is buffered and intercepted by the guide plate 74, so that the dust is guided by the guide plate 74 to the bottom of the guide plate 74, and enters the bottom hopper 72 through the filter 75 and is stored. At the same time, the guide plate 74 is used as an interception structure shielding the filter 75 to prevent the airflow from being directly blown to the bottom of the bottom hopper 72, and the dust collected in the bottom hopper 72 is blown out to prevent the dust from flowing back or escaping, thereby ensuring the one-way collection and storage function of the bottom hopper 72 for dust.

[0057] Furthermore, by filtering and intercepting the dust through the filter 75, larger dust particles can be intercepted separately on the filter 75, thereby achieving a preliminary classification of the dust particles generated during the grinding operation, and providing a pre-screening basis for the subsequent recycling of the dust.

[0058] During the grinding of stainless steel screws, the bottom of the stainless steel screw is magnetically positioned by the electromagnetic rod 9, so that the top and bottom of the stainless steel screw are always in the rotational motion of the same axis. The metal dust generated during the grinding can also be separately adsorbed and collected on the surface of the electromagnetic rod 9 in real time, which can not only reduce the hidden dangers of metal dust splashing or lasing, but also reduce the escape range of metal dust inside the box 1. Combined with the surrounding shielding and interception of dust by the protective sleeve 6 and the one-way collection of dust by the bottom bucket 72, the pollution of dust to the surrounding working environment during the grinding of stainless steel screws can be comprehensively reduced, and the subsequent maintenance and cleaning work of the grinding device can be reduced.

[0059] During the use of the grinding device, after the surface of the stainless steel screw is polished, the electromagnetic rod 9 can maintain the magnetic positioning effect on the bottom of the stainless steel screw, and the three-clamp cylinder 10 can be activated to loosen the clamp to release the top of the stainless steel screw. Then, as the clamp slowly opens, the electric telescopic push rod 13 is gradually activated to extend and press against the middle of the top of the stainless steel screw. At the same time, during this period, the electric cylinder 71 is activated to drive the long rod shaft 712 to descend, and the extension action of the electric telescopic push rod 13 is coordinated to lower the top of the stainless steel screw to the position in contact with the grinding disk 3. In this way, the top of the stainless steel screw can be polished by the grinding disk 3, so that the top of the stainless steel screw clamped in the clamp can also be polished in place, eliminating the grinding dead angle of the stainless steel screw, and realizing the comprehensive grinding of the stainless steel screw by the grinding device.

[0060] After the grinding of the stainless steel screw is completed, the hydraulic cylinder 4 and the electric cylinder 71 can be activated at the same time to move the stainless steel screw upward by the height of half the diameter of the grinding disc 3, and move the electromagnetic rod 9 downward by the height of half the diameter of the grinding disc 3, so that the electric slide can drive the grinding disc 3 at the right end of the grinding motor 2 to continue to move horizontally to the right without being blocked by the stainless steel screw, so that the grinding disc 3 passes the station where it contacts and grinds the stainless steel screw, and the grinding brush 82 is moved to the grinding station, and the grinding motor 2 drives the grinding brush 82 on the extension shaft 81 to grind the surface of the stainless steel screw to remove the dust and The fine burrs are thoroughly polished and removed, and the dead corners of the oxide layer remaining on the surface of the stainless steel screws are supplemented and polished to remove these oxide layers, improve the smoothness of the screw surface, reduce the surface roughness, remove small surface defects and residual contaminants, and improve the corrosion resistance of the stainless steel screws. At the same time, this secondary fine polishing method can be used to repair slight scratches or damage on the surface of the stainless steel screws, repair these defects, and for the threaded part of the stainless steel screws, it can remove irregularities in the manufacturing process, ensure that the thread fits more tightly and accurately, improve the thread fit of the stainless steel screws, and improve the overall quality of the product.

[0061] After the grinding brush 82 finishes grinding the stainless steel screw, the paint brush 83 can be translated to the grinding station in contact with the stainless steel screw through the same operation method as mentioned above, and the pump 85 can be activated to transport the paint in the paint box 86 to the inside of the paint brush 83 through the annular adapter tube 84, so that the paint is precipitated from the surface of the paint brush 83, and the grinding motor 2 drives the paint brush 83 to contact the surface of the stainless steel screw, so that a layer of rust prevention or protective layer can be evenly applied on the surface of the stainless steel screw, and after the above two grinding operations, based on the structure of the regular threaded surface provided, the coating is more uniform and firm, thereby ensuring the quality of the stainless steel screw. Among them, according to specific processing requirements, the paint in the paint box 86 can be replaced with the required paint, and the paint brush 83 can be used to uniformly brush the surface of the stainless steel screw, so that the grinding device has multifunctionality.

[0062] The second embodiment is based on the first embodiment. Figures 5 to 9 As shown, the middle part of the clamping unit 11 is installed with the clamping latch of the three-clamping cylinder 10, and the two sides of the clamping unit 11 away from the clamping are hinged with clamping blocks 111, and the hinged part of the clamping block 111 and the clamping unit 11 is installed with a torsion spring, and the clamping block 111 is installed by fitting with the surface of the stainless steel screw through the torsion spring.

[0063] When in use, through the design of the clamping unit 11, the clamping block 111 can be combined with the symmetrical assembly of the torsion spring on both sides of the clamping unit 11 to jointly increase the clamping contact area between the clamping on the three-clamp cylinder 10 and the top of the stainless steel screw. At the same time, the three-clamp cylinder 10 can be cooperated to achieve stable clamping and fixation of stainless steel screws of different models and sizes. During the grinding, the stainless steel screw can be coaxially rotated and ground around the electromagnetic rod 9 and the three-clamp cylinder 10 under the guidance of the magnetic attraction positioning support of the electromagnetic rod 9 on the bottom of the stainless steel screw, thereby ensuring the smooth rotation of the stainless steel screw on the fixed axis and ensuring the grinding accuracy of the stainless steel screw.

[0064] The third embodiment is based on the first and second embodiments. Figures 10 to 13 As shown, a long rod shaft 712 is installed in the middle of the top of the electric cylinder 71, the long rod shaft 712 is connected to the output end of the electric cylinder 71 through a first coupling, the guide plate 74 is fitted with the electromagnetic rod 9, the long rod shaft 712 is rotatably connected to the electromagnetic rod 9, and the long rod shaft 712 is inserted into the bottom bucket 72.

[0065] A pair of straight guide rods 711 are inserted at the top of the electric cylinder 71. The pair of straight guide rods 711 are installed around the long rod shaft 712 in a centrally symmetrical shape. The straight guide rods 711 penetrate the bottom bucket 72 and are connected to the guide plate 74, and the long rod shaft 712 and the middle part of the filter screen 75 are penetrated and installed.

[0066] After the grinding of the stainless steel screws is completed, the electric cylinder 71 is activated to drive the long rod shaft 712 to retract, so that the electromagnetic rod 9 and the stationary guide plate 74 can be pulled downward and moved, and the guide plate 74 can be used to scrape the metal dust magnetically attracted to the surface of the electromagnetic rod 9 onto the guide plate 74, and the guide plate 74 can be used to separately collect and store the metal dust, so as to facilitate the subsequent separate recovery of the metal dust and reuse.
