Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, and in particular to a grinding device for metal parts. Background Art

[0002] During the processing of metal parts, burrs and other foreign objects generated on the surface of the metal parts need to be polished to ensure a smooth surface. The traditional polishing device uses bolts to fix the position of the grinder, fixes the metal parts through the guide rails and clamps at the bottom, and then pushes the guide rails and metal parts to move horizontally to achieve contact with the grinding disc on the grinder and perform the polishing operation. When polishing different metal parts, the angle of the grinder needs to be adjusted to adapt to different polishing positions. The traditional polishing device is inconvenient to adjust the position of the grinder. It is necessary to disassemble multiple sets of fastening bolts and tighten them after adjusting the position. The operation is cumbersome and inconvenient for positioning. If there is still a deviation in the angle adjustment, the above steps need to be repeated, which is time-consuming and laborious.

[0003] In order to solve the above problems, a Chinese patent with publication number CN219359055U discloses a grinding device for metal casting processing, including a grinding guide rail seat, a support frame fixedly connected to the grinding guide rail seat, a support rod fixedly connected to the support frame, a fixed platform fixedly connected to the support rod, a rotating table rotatably connected to the fixed platform, a grinding machine body fixedly connected to the rotating table, a grinding disc fixedly connected to the output end of the grinding machine body, and an angle adjustment mechanism corresponding to the rotating table provided on the fixed platform. The device realizes the adjustment of the angle of the grinding disc, thereby realizing the grinding operation of the positions of different metal castings, ensuring a good grinding effect on the edge positions of the metal castings.

[0004] The above-mentioned device has the following problems during actual use: when the grinding disc is grinding the metal casting, since there is no cooling mechanism on the device to cool the grinding disc, the friction between the grinding disc and the metal casting will generate a large amount of heat, which will cause the grinding disc to be too hot and increase wear, thereby damaging the quality of the grinding disc, reducing the use effect, and reducing the grinding efficiency; in addition, a large amount of debris will be generated during grinding, and the debris will splash in the absence of coolant, causing pollution to the working environment and harm to human life and health. Summary of the invention

[0005] The invention provides a grinding device for metal parts, so as to solve the problem that the existing grinding device cannot cool the grinding disc when the grinding disc is grinding the metal parts.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a grinding device for metal parts, comprising a grinding box with a bottom opening; also comprising a grinding mechanism arranged in the grinding box; the grinding mechanism comprises a hollow shaft, a conduit, a grinding block, a cooling assembly symmetrically arranged on both sides of the hollow shaft along the axial direction of the hollow shaft, a driving assembly for driving the hollow shaft to rotate, and a booster assembly for introducing coolant into the conduit; the hollow shaft is rotatably connected to the grinding box; the conduit is fixedly connected to the inner wall of the hollow shaft; the grinding block is fixedly connected to the hollow shaft; the cooling assembly comprises a water outlet pipe, a side hole opened on the hollow shaft, and a plurality of water outlet holes are equidistantly opened along the axial direction of the water outlet pipe; the water outlet pipe passes through the side hole, the water outlet pipe is communicated with the conduit, and the water outlet pipe is connected to the conduit; the water outlet hole faces the grinding disc.

[0007] The principles and advantages of this solution are:

[0008] 1. The worker places the metal part to be polished against the polishing block, and while the polishing block is rotating, the metal part is continuously moved by the robotic arm to complete the polishing of the metal part; while the metal part is moving, the hollow shaft is driven to rotate by the driving assembly, and during the rotation of the hollow shaft, the polishing block rotates synchronously; while the polishing block is rotating, the polishing block can polish the moving metal part, thereby removing burrs, rust, and defects on the surface of the metal part, thereby enhancing the glossiness of the metal part surface, and improving the glossiness and reflectivity of the metal part surface, that is, improving the quality of the metal part surface and making the metal part beautiful.

[0009] 2. While the grinding block is grinding metal parts, the coolant is introduced into the conduit through the booster component. After the coolant flows into the conduit, the coolant will pass through the outlet pipe and finally be discharged along the outlet hole. The coolant discharged along the outlet hole has a certain force under the action of the booster component, so that the coolant can act on the grinding block and form a sputtering liquid. The sputtering liquid will splash around the grinding block, thereby expanding the action range of the sputtering liquid, making the sputtering liquid contact with the grinding block more fully, and enhancing the effect of the sputtering liquid.

[0010] Through the above movement, under the action of the coolant, the friction heat generated between the grinding block and the metal part surface can be reduced, playing a cooling role, ensuring that the grinding block and the metal part will not be deformed or damaged due to excessive heat; in addition, the coolant can form a liquid film on the metal surface to play a lubricating role, thereby reducing the friction resistance and the wear of the grinding block during the grinding process, and improving the grinding efficiency and quality; at the same time, the coolant can flush impurities and grinding debris on the surface of the metal part, maintain the cleanliness of the metal part surface, and avoid secondary pollution.

[0011] In summary, by moving the metal parts, the combined effect of the grinding block and the coolant can, on the one hand, reduce the heat generated by the grinding block during grinding and enhance the grinding effect; on the other hand, it can reduce the wear of the grinding block and thus improve the grinding quality.

[0012] Furthermore, it also includes a linkage part arranged on the conduit; the linkage part includes a linkage tube, a chamber opened on the grinding block, and a plurality of linkage holes equidistantly opened along the length direction of the chamber; the two ends of the linkage tube are respectively connected to the conduit and the chamber; the end of the linkage hole away from the chamber is flush with the lower surface of the grinding block.

[0013] While the coolant is in the conduit, a portion of the coolant will enter the chamber along the linkage pipe and finally be discharged from the linkage hole; through the above movement, the coolant can directly penetrate into the position where the grinding block and the metal part are in contact, so that the coolant can further enhance the lubrication and cooling effects, thereby ensuring that the grinding block and the metal parts will not be damaged due to the temperature increase caused by grinding, thereby enhancing the grinding effect and improving the grinding efficiency.

[0014] Furthermore, it also includes an annular rack arranged on one side of the outer wall of the hollow shaft; the annular rack is fixedly connected to the polishing box; the water outlet pipe is rotatably connected to the conduit; a first gear is fixedly connected to the water outlet pipe; and the first gear is meshed with the annular rack.

[0015] During the movement of the water outlet pipe, the first gear moves synchronously; during the movement of the first gear, since the first gear is engaged with the annular rack, the first gear rotates and the water outlet pipe rotates synchronously; therefore, the water outlet pipe can rotate while making circumferential motion.

[0016] During the rotation of the water outlet pipe, the water outlet pipe has a certain centrifugal force; therefore, the coolant will diffuse over a wider range under the action of the centrifugal force, so that the coolant can act on the surface of the grinding block over a large area, thereby expanding the contact area between the coolant and the grinding block, improving the utilization rate of the coolant, and enhancing the effect of the coolant, that is, ensuring that the temperature of the grinding block and the metal parts can drop quickly.

[0017] Furthermore, an auxiliary part is provided on the water outlet pipe; the auxiliary part includes an auxiliary pipe and a plurality of auxiliary units equidistantly arranged along the length direction of the auxiliary pipe; the auxiliary pipe is fixedly connected to the water outlet pipe, and the auxiliary pipe is communicated with the water outlet hole; the auxiliary unit includes a water guide pipe, a blocking block, an atomizing nozzle, a conical pipe, a second gear, an arc-shaped rack, and mounting holes are symmetrically provided on both sides along the diameter direction of the blocking block; the water guide pipe is communicated with the auxiliary pipe; the blocking block is fixedly connected to the inner wall of the water guide pipe away from one end of the auxiliary pipe; the atomizing nozzle and the conical pipe are fixedly connected to the mounting hole respectively; an annular groove is provided on the auxiliary pipe, and a plurality of connecting rods are fixedly connected along the circumferential direction of the second gear, and the connecting rods are slidably connected to the annular groove; the second gear is in contact with the free end of the water guide pipe, and a through hole is provided on the second gear, and the through hole is communicated with the mounting hole; connecting blocks are symmetrically provided on both sides along the axial direction of the hollow shaft; the connecting block is fixedly connected to the outer wall of the hollow shaft; the arc-shaped rack is fixedly connected to the connecting block, and the arc-shaped rack is located on the movement trajectory of the second gear, and the second gear can mesh with the arc-shaped rack.

[0018] During the rotation of the water outlet pipe, the auxiliary pipe rotates synchronously; during the rotation of the auxiliary pipe, the water guide pipe rotates synchronously; during the rotation of the water guide pipe, the second gear rotates synchronously; during the rotation of the second gear, when the second gear engages with the arc-shaped rack, the second gear rotates half a circle; during the rotation of the second gear, the through hole changes position so that the through hole communicates with one mounting hole and the other mounting hole is sealed; through the above movement, each time the second gear engages with the arc-shaped rack, one mounting hole will be sealed and the other mounting hole will be communicated with the through hole, and this intermittent cyclic movement realizes that the through hole is communicated with the two mounting holes in sequence.

[0019] When the mounting hole where the atomizing nozzle is located is connected to the through hole, the coolant discharged from the water pipe is atomized coolant; the atomized coolant can better suppress the dust generated by the grinding block during grinding, so that the dust will not spread out, ensuring that the dust generated by the grinding block during grinding will not pollute the environment and cause harm to the human body; and, because the water pipe can rotate while making circumferential motion, the atomized coolant can be diffused over a large area, ensuring that the atomized coolant can contact the dust more comprehensively, thereby further enhancing the dust reduction effect and improving the dust reduction efficiency, that is, improving the working environment and enhancing the working comfort.

[0020] When the mounting hole where the tapered tube is located is connected to the through hole, the coolant discharged from the water pipe can be ejected with stronger force under the action of the tapered tube; after the coolant is pressurized by the tapered tube, the sputtering liquid formed when the coolant contacts the grinding block has a wider diffusion range, thereby further expanding the contact area between the sputtering liquid and the grinding block, ensuring that the grinding block can be quickly cooled down under the action of the sputtering liquid, thereby improving the grinding quality and efficiency.

[0021] In summary, by setting two different modes of atomizing nozzle and conical tube and exchanging them back and forth, the grinding quality of the grinding block on metal parts is comprehensively improved, the grinding effect is enhanced, and the grinding quality is improved.

[0022] Furthermore, the conduit is connected with a boosting pipe; one end of the boosting pipe away from the conduit is fixedly connected with a rubber head; and a boosting member for driving the rubber head to deform is also included.

[0023] The rubber head is continuously deformed by the booster. During the deformation of the rubber head, the rubber head can compress the air, so that the compressed air enters the duct. After the compressed air enters the duct, the flow rate of the coolant can be increased, thereby increasing the pressure of the coolant when it is discharged, so that the coolant can have a more sufficient and complete cooling effect on the grinding block.

[0024] Furthermore, it also includes a boosting unit arranged in the auxiliary pipe; the boosting unit includes a boosting block, a boosting hole group opened on the boosting block, and a moving part used to drive the boosting block to reciprocate along the length direction of the auxiliary pipe; the boosting block is slidably connected to the auxiliary pipe; the boosting hole group includes a plurality of boosting holes, and the diameters of the plurality of boosting holes gradually decrease along the length direction of the auxiliary pipe away from the position where the first gear is located, and the boosting holes are communicated with the water pipe, and the water pipe is located on the movement trajectory of the boosting holes.

[0025] The boost block is driven to perform reciprocating motion along the length direction of the auxiliary pipe by the moving parts; during the movement of the boost block, the diameters of a plurality of boost holes are gradually reduced along the length direction of the auxiliary pipe toward a position away from the first gear, thereby further enhancing the force of coolant discharge by changing the caliber of the water pipe, that is, the range of action of the coolant is more comprehensive, the cooling effect is more significant, and the cooling quality of the coolant on the grinding block is further guaranteed.

[0026] Furthermore, it also includes a heat dissipation unit arranged on one side of the hollow shaft; the heat dissipation unit includes a rotating shaft, fan blades, and a power part for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the polishing box; the fan blades are fixedly connected to the rotating shaft, and the fan blades face the polishing block.

[0027] The rotating shaft is driven to rotate by the power part, and the fan blades rotate synchronously during the rotation of the rotating shaft; during the rotation of the fan blades, cold air can be delivered to the grinding block to increase the heat dissipation method, so that the grinding block can be quickly cooled down with the cooperation of the coolant and the cold air; at the same time, during the rotation of the fan blades, the effective distance of the atomized coolant can be further increased and the effective range of the atomized coolant can be expanded, so that the dust reduction effect of the atomized coolant on the dust is further made more significant, that is, the dust reduction time is shortened and the dust reduction efficiency is improved.

[0028] Moreover, during the rotation of the fan blades, the dust can be dispersed so that the dust does not gather; at the same time, it is beneficial to the circulation of air during grinding and enhances the ventilation effect, that is, it increases the flow rate of the atomized coolant and air and shortens the dust removal time.

[0029] Furthermore, the driving assembly includes a third gear and a fourth gear; the third gear is fixedly connected to the rotating shaft; the fourth gear is fixedly connected to the hollow shaft, and the third gear is meshed with the fourth gear.

[0030] During the rotation of the shaft, the third gear rotates synchronously; during the rotation of the third gear, the third gear is meshed with the fourth gear, and then the fourth gear; during the rotation of the fourth gear, the hollow shaft rotates synchronously.

[0032] During the rotation of the rotating shaft, the second bevel gear rotates synchronously; during the rotation of the second bevel gear, the first bevel gear rotates due to the meshing of the first bevel gear and the second bevel gear; during the rotation of the first bevel gear, the rotating shaft rotates synchronously; during the rotation of the rotating shaft, the cam rotates synchronously; during the rotation of the cam, when the raised portion of the cam abuts against the piston block, the piston block moves vertically downward, the first spring is compressed, and when the raised portion of the cam no longer abuts against the piston block, the piston block is reset under the action of the first spring, and the piston block moves vertically upward; therefore, the piston block can perform vertical reciprocating motion.

[0033] During the vertical reciprocating motion of the piston block, the piston block can continuously pump and drain water; during the vertical upward motion of the piston block, the piston block pumps water, and the coolant enters the piston cylinder along the water inlet pipe and is temporarily stored; during the vertical downward motion of the piston block, the piston block drains water, and the coolant stored in the piston cylinder enters the conduit along the drain pipe.

[0034] Furthermore, the booster is a slider; the slider is slidably connected to the piston cylinder, the slider is fixedly connected to the piston block, and the rubber head is located on the movement track of the slider.

[0035] During the vertical reciprocating motion of the piston block, the slider moves synchronously; during the motion of the slider; during the motion of the slider, when the slider contacts the rubber head, the slider continues to move, and then the rubber head is deformed, the internal pressure of the rubber head increases, and the air in the rubber head is compressed; when the slider is no longer in contact with the rubber head, the rubber head recovers, and the air in the rubber head is discharged along the air outlet of the boost pipe; therefore, the rubber head can continuously release compressed air into the conduit.

[0064] Through the above-mentioned movement, under the action of the coolant, the friction heat generated between the grinding block 4 and the surface of the metal part can be reduced, playing a cooling role, ensuring that the grinding block 4 and the metal part will not be deformed or damaged due to excessive heat; in addition, the coolant can form a liquid film on the metal surface to play a lubricating role, thereby reducing the friction resistance and the wear degree of the grinding block 4 during the grinding process, and improving the grinding efficiency and quality; at the same time, the coolant can flush impurities and grinding debris on the surface of the metal part, maintain the cleanliness of the surface of the metal part, and avoid secondary pollution.

[0065] In summary, by moving the metal parts, the combined effect of the grinding block 4 and the coolant can, on the one hand, reduce the heat generated by the grinding block 4 during grinding and enhance the grinding effect; on the other hand, reduce the wear of the grinding block 4 and thus improve the grinding quality.

[0066] While the coolant is in the conduit 3, a portion of the coolant will enter the chamber 8 along the linkage tube 7 and finally be discharged from the linkage hole 9; through the above movement, the coolant can directly penetrate into the position where the grinding block 4 and the metal part are in contact, so that the coolant can further enhance the lubrication and cooling effects, thereby ensuring that the grinding block 4 and the metal part will not be damaged in quality due to the temperature increase caused by grinding, thereby enhancing the grinding effect and improving the grinding efficiency.

[0067] During the movement of the water outlet pipe 5, the first gear 11 moves synchronously; during the movement of the first gear 11, since the first gear 11 is engaged with the annular rack 10, the first gear 11 rotates and the water outlet pipe 5 rotates synchronously; therefore, the water outlet pipe 5 can rotate while making circumferential motion.

[0068] During the movement of the water outlet pipe 5, the wedge block 43 moves synchronously; during the movement of the wedge block 43, when the wedge block 43 moves to the crest of the arc-shaped protrusion 45, the second spring 44 is compressed, and the boost block 24 moves along the length direction of the auxiliary pipe 12 toward the position where the first gear 11 is located; when the wedge block 43 moves to the trough, that is, the connection between two adjacent arc-shaped protrusions 45, the boost block 24 is reset under the action of the second spring 44, and the boost block 24 moves along the length direction of the auxiliary pipe 12 toward the position away from the first gear 11.

[0069] During the reciprocating motion of the boost block 24 along the length direction of the auxiliary tube 12, the diameter of a plurality of boost holes 25 is gradually reduced along the length direction of the auxiliary tube 12 toward the position away from the first gear 11, and then the force of the coolant discharge can be further enhanced by changing the diameter of the water pipe 13, that is, the range of action of the coolant is more comprehensive, and the cooling effect is more significant, which further ensures the cooling quality of the coolant on the grinding block 4.

[0070] During the rotation of the water outlet pipe 5, the water outlet pipe 5 has a certain centrifugal force; therefore, the coolant will diffuse over a wider range under the action of the centrifugal force, so that the coolant can act on the surface of the grinding block 4 over a large area, thereby expanding the contact area between the coolant and the grinding block 4, improving the utilization rate of the coolant, and enhancing the effect of the coolant, that is, ensuring that the temperature of the grinding block 4 and the metal part can drop rapidly.

[0071] During the rotation of the water outlet pipe 5, the auxiliary pipe 12 rotates synchronously; during the rotation of the auxiliary pipe 12, the water conduit 13 rotates synchronously; during the rotation of the water conduit 13, the second gear 17 rotates synchronously; during the rotation of the second gear 17, when the second gear 17 engages with the arc-shaped rack 18, the second gear 17 rotates half a circle; during the rotation of the second gear 17, the through hole 20 changes position, so that the through hole 20 communicates with one mounting hole and the other mounting hole is sealed; through the above movement, each time the second gear 17 engages with the arc-shaped rack 18, one mounting hole will be sealed and the other mounting hole will communicate with the through hole 20, so that the intermittent cyclic movement is realized, so that the through hole 20 is communicated with the two mounting holes in sequence.

[0072] When the mounting hole where the atomizing nozzle 15 is located is connected to the through hole 20, the coolant discharged from the water pipe 13 is atomized coolant; the atomized coolant can better reduce the dust generated by the grinding block 4 during grinding, so that the dust will not spread out, ensuring that the dust generated by the grinding block 4 during grinding will not pollute the environment or cause harm to the human body; and, because the water pipe 13 can rotate while making circumferential motion, the atomized coolant can be diffused over a large area, ensuring that the atomized coolant can contact the dust more comprehensively, thereby further enhancing the dust reduction effect and improving the dust reduction efficiency, that is, improving the working environment and enhancing the working comfort.

[0073] When the mounting hole where the tapered tube 16 is located is connected to the through hole 20, the coolant discharged from the water pipe 13 can be ejected with stronger force under the action of the tapered tube 16; after the coolant is pressurized by the tapered tube 16, the sputtering liquid formed when the coolant contacts the grinding block 4 has a wider diffusion range, thereby further expanding the contact area between the sputtering liquid and the grinding block 4, ensuring that the grinding block 4 can be quickly cooled down under the action of the sputtering liquid, thereby improving the grinding quality and efficiency.

[0074] In summary, by setting two different modes of the atomizing nozzle 15 and the tapered tube 16 and exchanging them back and forth, the grinding quality of the grinding block 4 on the metal part is comprehensively improved, the grinding effect is enhanced, and the grinding quality is improved.

[0075] During the vertical reciprocating motion of the piston block 33, the slider 41 moves synchronously; during the motion of the slider 41; during the motion of the slider 41, when the slider 41 contacts the rubber head 23, the slider 41 continues to move, and then the rubber head 23 is deformed, and the internal pressure of the rubber head 23 increases, so that the air in the rubber head 23 is compressed; when the slider 41 is no longer in contact with the rubber head 23, the rubber head 23 recovers, and the air in the rubber head 23 is discharged along the air outlet of the boost pipe 22; therefore, the rubber head 23 can continuously release compressed air into the conduit 3.

[0076] The rubber head 23 is continuously deformed by the slider 41. During the deformation of the rubber head 23, the rubber head 23 can compress the air so that the compressed air enters the conduit 3. After the compressed air enters the conduit 3, the flow rate of the coolant can be increased, thereby increasing the pressure of the coolant when it is discharged, so that the coolant can have a more sufficient and complete cooling effect on the grinding block 4.

[0077] During the rotation of the shaft 26, the fan blades 27 rotate synchronously; during the rotation of the fan blades 27, cold air can be delivered to the grinding block 4, increasing the heat dissipation method, so that the grinding block 4 can be quickly cooled down with the cooperation of the coolant and the cold air; at the same time, during the rotation of the fan blades 27, the effective distance of the atomized coolant can be further increased and the effective range of the atomized coolant can be expanded, further making the dust reduction effect of the atomized coolant on the dust more significant, that is, shortening the dust reduction time and improving the dust reduction efficiency.

[0078] Furthermore, during the rotation of the fan blades 27, the dust can be dispersed so that the dust does not gather; at the same time, it is beneficial to the circulation of air during grinding and enhances the ventilation effect, that is, the flow rate of the atomized coolant and air is increased, and the dust removal time is shortened.

[0079] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
