Description

Technical Field

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

[0002] When cutting existing columnar metal parts, it is necessary to manually control the clamps to fix the columnar metal parts on the workbench, which has poor stability during cutting and needs to be manually disassembled after each cutting, resulting in high labor intensity.

[0003] In order to solve the above problems, a Chinese patent with publication number CN219254325U discloses a metal parts cutting device, including a workbench, a cutting mechanism fixedly connected to the upper end of the workbench, a fixing mechanism provided inside the workbench and the front side of the upper end, the fixing mechanism including a rotating groove provided inside the workbench, a gear fixedly connected to the outer side of the rotating shaft, and a moving groove provided on both sides of the upper and lower sides of the workbench near the gear. The device rotates two sets of connecting plates along the fixing blocks through the movement of two sets of movable rods, and cooperates with the protrusions to move along the connecting grooves, and compresses the springs by pushing the two sets of fixing rods to move through the protrusions, thereby achieving the two sets of fixing rods to be fixed and clamped inward, effectively fixing the columnar metal parts, reducing the danger during work, and pushing the moving plate to move downward along the card slot through the output shaft of the cylinder, thereby achieving the purpose of cutting the columnar metal parts.

[0004] The above-mentioned device has the following problems during actual use: after the cutting of the cylindrical metal parts is completed, many burrs will remain on the cut surface. Since the device is not provided with a grinding mechanism to grind these burrs, on the one hand, it will affect the accuracy of the processing of the cylindrical metal parts, resulting in reduced cutting quality, and on the other hand, it is easy to cause scratches to the workers when they are carrying them, posing certain safety hazards; and, if the workers use grinding equipment to grind the burrs remaining on the surface of the cylindrical metal parts, on the one hand, they need to disassemble and assemble the processed cylindrical metal parts again at the grinding equipment, which is inefficient and not conducive to rapid processing, and on the other hand, it will increase the labor intensity of the workers and bring unnecessary work burden to the workers. Summary of the invention

[0005] The invention provides a cutting device for metal parts, so as to solve the problem that the existing cutting device cannot grind the burrs remaining on the cutting surface after cutting the columnar metal parts.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cutting device for metal parts, comprising a box body, side holes are opened on both sides of the box body, and mechanical arms are arranged on both sides of the box body: it also includes a grinding mechanism symmetrically arranged on both sides of the box body along the width direction of the box body; the grinding mechanism includes a limit frame, a limit ring, a guide block, a slider, a grinding block, a driving component for driving the slider to reciprocate along the length direction of the guide block, and a power component for driving the limit ring to rotate; the limit frame is fixedly connected to the box body; the limit ring is rotatably connected to the limit frame, and a positioning component for fixing the metal part is provided on the limit ring; the guide block is fixedly connected to the limit frame; the slider is slidably connected to the guide block; the grinding block is connected to the slider; and it also includes a cutting component arranged in the box body.

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

[0008] 1. Workers place the cylindrical metal parts to be polished into the box along the side holes. After the metal parts are placed, they are cut by the cutting assembly until the metal parts are cut. After the metal parts are cut, the two cut metal parts are moved away from each other by the robotic arm until the distance between the two metal parts can adapt to the polishing of the polishing block and the cut surface of the metal parts is on the movement trajectory of the polishing block.

[0009] 2. After the cutting surface of the metal part is located on the motion trajectory of the grinding block, the driving assembly drives the slider to reciprocate along the length direction of the guide block, and the grinding block moves synchronously during the movement of the slider; during the movement of the grinding block, the grinding block can grind the cutting surface of the metal part to make the surface of the cutting surface of the metal part smooth and will not injure the workers, and remove impurities on the surface to make the quality and surface properties of the cutting surface better; and, while the grinding block is grinding the cutting surface of the metal part, the positioning assembly is used to position the metal part, so that the metal part can rotate synchronously with the limit ring under the drive of the power assembly; during the rotation of the metal part, the grinding range of the grinding block on the metal part can be expanded, so that the grinding block can grind any position of the cutting surface of the metal part, thereby enhancing the grinding effect and improving the grinding efficiency.

[0010] 3. The metal parts are positioned by the positioning components so that they can be fixed. On the one hand, it ensures that the metal parts will not shake during grinding, thereby improving the grinding accuracy and ensuring the grinding quality. On the other hand, it can cooperate with the grinding of the grinding block to increase the grinding range of the grinding block on the metal parts, ensuring that any position of the cutting surface of the metal parts can be polished more completely and fully.

[0011] To sum up, through the joint action of the grinding block, positioning assembly, and power assembly, the cut surface of the metal part can be fully polished, which improves the quality of the metal part after cutting and enhances the performance of the metal part during use; at the same time, it ensures that the metal parts will not cause harm to the workers during subsequent transportation and storage, thereby protecting the workers' lives and health.

[0012] Furthermore, it also includes an auxiliary part arranged on the slider; the auxiliary part includes an auxiliary block, a short shaft, a first cam, a first spring, a side hole opened on the slider, and an auxiliary unit for driving the short shaft to rotate; the auxiliary block is vertically slidably connected to the side hole, the auxiliary block can make vertical reciprocating motion in the side hole, and the grinding block is fixedly connected to the auxiliary block; the short shaft is rotatably connected to the limit frame; the first cam is fixedly connected to the short shaft, and the first cam is against the auxiliary block; the two ends of the first spring are respectively connected to the auxiliary block and the side hole.

[0013] During the rotation of the short shaft, the first cam rotates synchronously; during the rotation of the first cam, when the raised portion of the first cam abuts against the auxiliary block, the auxiliary block moves vertically upward, and the first spring is stretched. When the raised portion of the first cam no longer abuts against the auxiliary block, the auxiliary block is reset under the action of the first spring, and the auxiliary block moves vertically downward; therefore, the auxiliary block can perform vertical reciprocating motion.

[0014] During the vertical reciprocating motion of the auxiliary block, the grinding block moves synchronously. Therefore, while the grinding block reciprocates along the length direction of the guide block, the grinding block can also reciprocate vertically. During the vertical reciprocating motion of the grinding block, the grinding block has a certain force, so the grinding block can more thoroughly grind the burrs remaining on the cutting surface of the metal part, ensuring that the burrs will not remain on the cutting surface of the metal part, further enhancing the grinding effect of the grinding block, and improving the grinding efficiency of the grinding block.

[0015] Furthermore, it also includes a linkage part arranged on the limit frame; the linkage part includes a cooling box, a piston cylinder, a piston block, a second spring, and a chamber opened in the slider; the cooling box is fixedly connected to the limit frame; the piston cylinder is fixedly connected to the limit frame; the piston block is vertically slidably connected to the piston cylinder, and the first cam is against the piston block; the two ends of the second spring are respectively connected to the piston block and the piston cylinder; the piston cylinder is respectively connected to a water inlet pipe and a hose; the water inlet pipe is connected to the cooling box; the hose is connected to the chamber; a plurality of water outlet pipes are equidistantly arranged along the length direction of the chamber; the water outlet pipe is connected to the slider, the water outlet pipe is communicated with the chamber, and the water outlet pipe faces the limit ring.

[0016] During the rotation of the first cam, when the raised portion of the first cam abuts against the piston block, the piston block moves vertically downward and the second spring is compressed. When the raised portion of the first cam no longer abuts against the piston block, the piston block is reset under the action of the second spring and moves vertically upward; therefore, the piston block can perform vertical reciprocating motion.

[0017] 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 flows into 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 enters the chamber along the hose, and is finally discharged along the water outlet pipe and can act on the cutting surface of the metal part.

[0018] When the coolant acts on the cutting surface of the metal surface, it can reduce the friction heat generated by the grinding block and the cutting surface of the metal part, play a cooling role, and ensure that the grinding block and the cutting surface of 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, reduce friction resistance and the wear of the grinding block during the grinding process, and improve the grinding efficiency and quality; at the same time, the coolant can flush impurities and grinding debris on the cutting surface of the metal part, maintain the cleanliness of the cutting surface of the metal part, and avoid secondary pollution.

[0019] Furthermore, a boosting unit is provided in the chamber; the boosting unit includes a vertical block, a boosting block, and a third spring; the vertical block is vertically slidably connected to the slider, the vertical block extends into the side hole, and the vertical block is located on the movement trajectory of the auxiliary block; the boosting block is fixedly connected to the vertical block, and the water outlet pipe is located on the movement trajectory of the boosting block; the two ends of the third spring are respectively connected to the boosting block and the chamber.

[0020] When the auxiliary block moves vertically upward, when the auxiliary block contacts the vertical block, the vertical block moves synchronously driven by the auxiliary block, and the third spring stretches. When the auxiliary block moves vertically downward, the vertical block resets under the action of the third spring. Therefore, the vertical block can perform vertical reciprocating motion.

[0021] During the movement of the vertical block, the boost block moves synchronously; during the movement of the boost block, when the boost block and the water outlet pipe gradually stick together, the water inlet aperture of the water outlet pipe will gradually shrink, that is, by controlling the change of the water inlet aperture of the water outlet pipe, the pressure in the water outlet pipe is increased, so that the coolant has a better cooling effect on the cutting surface of the metal part, the cooling efficiency is faster, and the flushing effect is more significant.

[0022] Moreover, after being pressurized, the coolant has a certain force, which enables the coolant to act on the cutting surface of the metal part and form a sputtering liquid. The sputtering liquid will splash around the cutting surface of the metal part, thereby expanding the action range of the sputtering liquid, making the sputtering liquid contact more fully with the grinding block and the metal part, and enhancing the effect of the sputtering liquid.

[0023] Furthermore, it also includes a first rack; the first rack is fixedly connected to the limit frame; a first gear is fixedly connected to the water outlet pipe, and the water outlet pipe is rotatably connected to the slider; the first gear is meshed with the first rack.

[0024] During the synchronous movement of the first gear with the slider, the first gear is engaged with the first rack, and then the first gear rotates. Therefore, the first gear can rotate while making reciprocating motion along the length direction of the guide block; during the rotation of the first gear, the water outlet pipe rotates synchronously.

[0025] 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 part can drop quickly, and the grinding block has a better grinding effect on the cut surface of the metal part.

[0026] Furthermore, it also includes an annular block fixedly connected to the limiting ring; a plurality of grooves are equidistantly provided along the circumferential direction of the annular block; the water outlet end of the water outlet pipe is connected with a rubber tube; and the annular block is located on the movement track of the rubber tube.

[0027] During the reciprocating motion of the rubber tube along the length direction of the guide block, when the rubber tube is in contact with the annular block, the rubber tube is deformed under the reaction force of the annular block, causing the water outlet diameter of the rubber tube to become smaller. When the rubber tube is no longer in contact with the annular block, the rubber tube recovers its deformation.

[0028] Through the above movement, the rubber tube can increase the force of the coolant during the recovery of deformation, that is, after the coolant is deformed by the rubber tube, so that when the coolant acts on the cutting surface of the metal part, the coolant splashes over a wider range, further increasing the contact area between the sputtering liquid and the grinding block and the cutting surface of the metal part, ensuring that the sputtering liquid can contact the grinding block and the cutting surface of the metal part more fully and comprehensively during sputtering, thereby enhancing the cooling effect, improving the cooling efficiency, and ensuring that the grinding quality of the cutting surface of the metal part by the grinding block is better.

[0029] Furthermore, it also includes a linkage unit symmetrically arranged on both sides of the box body along the width direction of the box body; the linkage unit includes a guide cylinder, a moving block, a fourth spring, a first annular rack, a first screw, a first guide rod, a first nut seat, and a driving member for driving the first screw to rotate; the guide cylinder is fixedly connected to the box body; the moving block is slidably connected to the guide cylinder; the two ends of the fourth spring are respectively connected to the moving block and the inner wall of the guide cylinder; the first annular rack is fixedly connected to the moving block; the first screw is rotatably connected to the box body; the first guide rod is fixed to the box body; the first nut seat is threadedly connected to the first screw, and the first nut seat is slidably connected to the first guide rod ; The first annular rack is located on the motion trajectory of the first nut seat; the positioning assembly includes a plurality of positioning parts equidistantly arranged along the circumferential direction of the limit ring; the positioning part includes a second screw, a second guide rod, a second nut seat, a clamping block, a second gear, and a through hole opened on the limit ring; the second screw and the second guide rod are both located in the through hole; the second screw is rotatably connected to the through hole, and the second guide rod is fixedly connected to the through hole; the second nut seat is threadedly connected to the second screw, and the second nut seat is slidably connected to the second guide rod; the clamping block is fixedly connected to the second nut seat; the second gear is fixedly connected to the second screw, and the second gear is meshed with the first annular rack.

[0030] The first screw is driven by the driving member to rotate forward, and during the forward rotation of the first screw; the first nut seat moves along the length direction of the first guide rod to a position away from the limit frame; during the movement of the first nut seat, when it has not yet contacted the first annular rack, during this period, the second screw and the second guide rod both rotate synchronously with the limit ring; during the rotation of the second screw along the circumferential direction of the annular rack, the second gear moves synchronously; during the circumferential movement of the second gear, the second gear is engaged with the first annular rack, and then the second gear rotates; during the rotation of the second gear, the second screw rotates synchronously, so the second While the screw rod is moving circumferentially, the second screw rod can also rotate; during the rotation of the second screw rod, the second nut seat moves along the length direction of the second guide rod toward the position where the metal part is located, and the clamping block moves synchronously; during the movement of the clamping block, until the clamping block abuts against the metal part, at this time, the first nut seat contacts the first annular rack, and the first nut seat drives the first annular rack to move toward the position close to the side hole, and the moving block compresses the fourth spring; during the synchronous movement of the first annular rack, that is, the first annular rack is no longer meshed with the second gear, during which time the metal part is positioned by the positioning block.

[0031] Similarly, when the second screw reverses, the first nut seat moves away from the side hole, and the first annular rack is reset under the action of the fourth spring until the first annular rack engages with the second gear again, so that the clamping block no longer positions the metal part, making it easier to remove the metal part after grinding is completed.

[0032] The positioning of the metal part by the clamping block enhances the positioning effect of the metal part, ensuring that the metal part can rotate synchronously with the limit ring under the action of the clamping block, thereby expanding the grinding range of the grinding block on the cutting surface of the metal part, enhancing the grinding effect and improving the grinding efficiency.

[0033] Furthermore, the driving assembly includes a rotating shaft, a second cam, and a fifth spring; the rotating shaft is rotatably connected to the limit frame, and the rotating shaft is fixedly connected to the first screw; the second cam is fixedly connected to the rotating shaft, and the second cam is against the slider; the two ends of the fifth spring are respectively connected to the slider and the guide block.

[0034] During the rotation of the first screw, the rotating shaft rotates synchronously; during the rotation of the rotating shaft, the second cam rotates synchronously; during the rotation of the second cam, when the raised portion of the second cam abuts against the slider, the slider moves along the length direction of the guide block away from the position where the rotating shaft is located, and the fifth spring is compressed. When the raised portion of the second cam no longer abuts against the slider, the slider is reset under the action of the fifth spring, and the slider moves along the length direction of the guide block toward the position where the rotating shaft is located; therefore, the slider can reciprocate along the length direction of the guide block.

[0035] Furthermore, the power assembly includes a third gear and a second annular rack; the third gear is fixedly connected to the rotating shaft; the second annular rack is fixedly connected to the limiting ring, and the third gear is meshed with the second annular rack.

[0036] During the rotation of the shaft, the third gear rotates synchronously. During the rotation of the third gear, the second annular rack rotates because the third gear meshes with the second annular rack. During the rotation of the second annular rack, the limit ring rotates synchronously.

[0037] Furthermore, the auxiliary unit includes a fourth gear and a second rack; the fourth gear is fixedly connected to the short shaft; the second rack is fixedly connected to the slider, and the second rack is meshed with the fourth gear.

[0038] During the movement of the slider, the second rack moves synchronously. During the movement of the second rack, the second rack meshes with the fourth gear, so that the fourth gear rotates; during the rotation of the fourth gear, the short shaft rotates synchronously.

After the metal part is placed, the cylinder 13 is started, and the movable block 9 is driven by the cylinder 13 to move toward the position close to the metal part; during the movement of the movable block 9, the motor 12 is started, and the rotating shaft 39 is driven to rotate by the output shaft of the motor 12; during the rotation of the rotating shaft 39, the cutting knife 11 rotates synchronously; during the rotation of the cutting knife 11, the cutting knife 11 can cut the metal part until the metal part is cut; after the metal part is cut, the two cut metal parts are moved away from each other by the robot arm 2 until the distance between the two metal parts can adapt to the polishing of the polishing block 7, and the cutting surface of the metal part is located on the movement trajectory of the polishing block 7.

[0063] After the cutting surface of the metal part is located on the motion trajectory of the grinding block 7, the servo motor 45 is started, and the first screw 51 is driven to rotate by the output shaft of the servo motor 45. During the rotation of the first screw 51, the rotating shaft 39 rotates synchronously; during the rotation of the rotating shaft 39, the second cam 40 rotates synchronously; during the rotation of the second cam 40, when the raised portion of the second cam 40 abuts against the slider 6, the slider 6 moves along the length direction of the guide block 5 away from the position where the rotating shaft 39 is located, and the fifth spring is compressed. When the raised portion of the second cam 40 no longer abuts against the slider 6, the slider 6 is reset under the action of the fifth spring, and the slider 6 moves along the length direction of the guide block 5 toward the position where the rotating shaft 39 is located; therefore, the slider 6 can reciprocate along the length direction of the guide block 5.

[0064] At the same time, during the rotation of the rotating shaft 39, the third gear 41 rotates synchronously. During the rotation of the third gear 41, since the third gear 41 is engaged with the second annular rack 42, the second annular rack 42 rotates; during the rotation of the second annular rack 42, the limit ring 4 rotates synchronously.

[0065] During the forward rotation of the first screw 51; the first nut seat 53 moves along the length direction of the first guide rod 52 away from the position where the limit frame 3 is located; during the movement of the first nut seat 53, before it contacts the first annular rack 33, during this period, the second screw 34 and the second guide rod 35 both rotate synchronously with the limit ring 4; during the rotation of the second screw 34 along the circumferential direction of the annular rack, the second gear 38 moves synchronously; during the circumferential movement of the second gear 38, the second gear 38 is engaged with the first annular rack 33, and then the second gear 38 rotates; during the rotation of the second gear 38, the second screw 34 rotates synchronously, so the second screw 34 moves circumferentially At the same time, the second screw 34 can also rotate; during the rotation of the second screw 34, the second nut seat 36 moves along the length direction of the second guide rod 35 to the position close to the metal part, and the clamping block 37 moves synchronously; during the movement of the clamping block 37, until the clamping block 37 is in contact with the metal part, at this time, the first nut seat 53 is in contact with the first annular rack 33, and the first nut seat 53 drives the first annular rack 33 to move to the position close to the side hole 10, and the moving block 50 compresses the fourth spring; during the synchronous movement of the first annular rack 33, that is, the first annular rack 33 is no longer meshed with the second gear 38, during this period, the metal part is positioned by the positioning block.

[0066] Similarly, when the second screw 34 reverses, the first nut seat 53 moves to a position away from the side hole 10, and the first annular rack 33 is reset under the action of the fourth spring until the first annular rack 33 engages with the second gear 38 again, so that the clamping block 37 no longer positions the metal part, thereby facilitating the removal of the metal part after grinding is completed.

[0067] Through the above-mentioned movement, the grinding block 7 moves synchronously during the movement of the slider 6; during the movement of the grinding block 7, the grinding block 7 can grind the cut surface of the metal part, so that the surface of the cut surface of the metal part is smooth and will not injure the workers, and remove impurities on the surface, so that the quality and surface properties of the cut surface are better; and, while the grinding block 7 is grinding the cut surface of the metal part, the metal part is positioned by the clamping block 37, so that the metal part can rotate synchronously with the limit ring 4 under the drive of the limit ring 4; during the rotation of the metal part, the grinding range of the metal part by the grinding block 7 can be expanded, so that the grinding block 7 can grind any position of the cut surface of the metal part, thereby enhancing the grinding effect and improving the grinding efficiency.

[0068] The metal part is positioned by the clamping block 37 so that it can be fixed. On the one hand, it ensures that the metal part will not shake during grinding, thereby improving the grinding accuracy and ensuring the grinding quality. On the other hand, it can cooperate with the grinding of the grinding block 7 to increase the grinding range of the grinding block 7 on the metal part, ensuring that any position of the cut surface of the metal part can be polished more completely and fully.

[0069] To sum up, through the joint action of the grinding block 7, the limit block 47 and the tightening block 37, the cut surface of the metal part can be fully polished, which improves the quality of the metal part after cutting and enhances the performance of the metal part during use; at the same time, it ensures that the metal parts will not cause harm to the workers during subsequent transportation and storage, thereby protecting the lives and health of the workers.

[0070] During the movement of the slider 6, the second rack 44 moves synchronously. During the movement of the second rack 44, the second rack 44 is engaged with the fourth gear 43, so that the fourth gear 43 rotates; during the rotation of the fourth gear 43, the short shaft 15 rotates synchronously.

[0071] During the rotation of the short shaft 15, the first cam 16 rotates synchronously; during the rotation of the first cam 16, when the raised portion of the first cam 16 abuts against the auxiliary block 14, the auxiliary block 14 moves vertically upward, and the first spring 17 is stretched. When the raised portion of the first cam 16 no longer abuts against the auxiliary block 14, the auxiliary block 14 is reset under the action of the first spring 17, and the auxiliary block 14 moves vertically downward; therefore, the auxiliary block 14 can perform vertical reciprocating motion.

[0072] During the vertical reciprocating motion of the auxiliary block 14, the grinding block 7 moves synchronously. Therefore, while the grinding block 7 reciprocates along the length direction of the guide block 5, the grinding block 7 can also reciprocate vertically. During the vertical reciprocating motion of the grinding block 7, the grinding block 7 has a certain force, so that the grinding block 7 can grind the burrs remaining on the cutting surface of the metal part more thoroughly, ensuring that the burrs will not remain on the cutting surface of the metal part, further enhancing the grinding effect of the grinding block 7, and improving the grinding efficiency of the grinding block 7.

[0073] During the rotation of the first cam 16, when the raised portion of the first cam 16 abuts against the piston block 21, the piston block 21 moves vertically downward and the second spring 22 is compressed. When the raised portion of the first cam 16 no longer abuts against the piston block 21, the piston block 21 is reset under the action of the second spring 22 and moves vertically upward; therefore, the piston block 21 can perform vertical reciprocating motion.

[0074] During the vertical reciprocating motion of the piston block 21, the piston block 21 can continuously pump and drain water; during the vertical upward motion of the piston block 21, the piston block 21 pumps water, and the coolant flows into the piston cylinder 20 along the water inlet pipe 23 and is temporarily stored; during the vertical downward motion of the piston block 21, the piston block 21 drains water, and the coolant enters the chamber 28 along the hose 24, and is finally discharged along the water outlet pipe 48 and can act on the cutting surface of the metal part.

[0075] When the coolant acts on the cutting surface of the metal surface, it can reduce the friction heat generated by the grinding block 7 and the cutting surface of the metal part, play a cooling role, and ensure that the grinding block 7 and the cutting surface of the metal part will not be deformed or damaged due to excessive heat; moreover, the coolant can form a layer of liquid film on the metal surface to play a lubricating role, reduce the friction resistance and the wear degree of the grinding block 7 during the grinding process, and improve the grinding efficiency and quality; at the same time, the coolant can flush the impurities and grinding debris on the cutting surface of the metal part, maintain the cleanliness of the cutting surface of the metal part, and avoid secondary pollution.

[0076] When the auxiliary block 14 moves vertically upward, when the auxiliary block 14 abuts against the vertical block 25, the vertical block 25 moves synchronously driven by the auxiliary block 14, and the third spring 27 is stretched. When the auxiliary block 14 moves vertically downward, the vertical block 25 is reset under the action of the third spring 27. Therefore, the vertical block 25 can perform vertical reciprocating motion.

[0077] During the movement of the vertical block 25, the boost block 26 moves synchronously; during the movement of the boost block 26, when the boost block 26 and the water outlet pipe 48 gradually stick together, the water inlet aperture of the water outlet pipe 48 will gradually shrink, that is, by controlling the change of the water inlet aperture of the water outlet pipe 48, the pressure in the water outlet pipe 48 is increased, so that the coolant has a better cooling effect on the cutting surface of the metal part, the cooling efficiency is faster, and the flushing effect is more significant.

[0078] Moreover, after being pressurized, the coolant has a certain force, which enables the coolant to act on the cutting surface of the metal part and form a sputtering liquid. The sputtering liquid will splash around the cutting surface of the metal part, thereby expanding the action range of the sputtering liquid, making the sputtering liquid contact more fully with the grinding block 7 and the metal part, and enhancing the effect of the sputtering liquid.

[0079] During the period when the first gear 30 moves synchronously with the slider 6, since the first gear 30 is engaged with the first rack 29, and then the first gear 30 rotates, the first gear 30 can rotate while making reciprocating motion along the length direction of the guide block 5; during the rotation of the first gear 30, the water outlet pipe 48 rotates synchronously.

[0080] During the rotation of the water outlet pipe 48, the water outlet pipe 48 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 7 over a large area, thereby expanding the contact area between the coolant and the grinding block 7, improving the utilization rate of the coolant, and enhancing the effect of the coolant, that is, ensuring that the temperature of the grinding block 7 and the metal part can drop quickly, and the grinding block 7 has a better grinding effect on the cut surface of the metal part.

[0081] During the reciprocating motion of the rubber tube 32 along the length direction of the guide block 5, when the rubber tube 32 is in contact with the annular block 31, the rubber tube 32 is deformed under the reaction force of the annular block 31, so that the diameter of the water outlet pipe 48 of the rubber tube 32 becomes smaller. When the rubber tube 32 is no longer in contact with the annular block 31, the rubber tube 32 recovers its deformation.

[0082] Through the above-mentioned movement, the rubber tube 32 can increase the force of the coolant during the recovery of the deformation, that is, after the coolant is deformed by the rubber tube 32, so that when the coolant acts on the cutting surface of the metal part, the coolant splashes over a wider range, further increasing the contact area between the sputtering liquid and the grinding block 7 and the cutting surface of the metal part, ensuring that the sputtering liquid can contact the grinding block 7 and the cutting surface of the metal part more fully and comprehensively during the sputtering period, thereby enhancing the cooling effect, improving the cooling efficiency, and ensuring that the grinding quality of the cutting surface of the metal part by the grinding block 7 is better.

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.
