Description

Technical Field

[0001] This invention belongs to the field of grinding technology, specifically a three-sided forming grinding machine for guideway processing. Background Technology

[0002] A guide rail is a mechanical component used to guide and restrict the movement trajectory of an object. A guide rail allows a component to reciprocate along a set precise path while bearing the load on it. Guide rail machining is the process of manufacturing a guide component that meets the requirements of straightness, parallelism, hardness, wear resistance, and surface roughness by using a series of processes such as cutting, heat treatment, precision grinding, and surface treatment on a metal blank. A three-sided forming grinder is a high-precision CNC grinder that can grind three sides in one clamping. It is specially designed for the simultaneous precision forming grinding of the top surface and the left and right sides of long strip workpieces such as linear guide rails, and is the core equipment for high-end guide rail machining.

[0003] When using existing three-sided profile grinding machines for guideway processing, the machine bed experiences uneven temperature gradients due to multiple heat sources, including grinding heat conduction, motor radiation, hydraulic system heat dissipation, and environmental fluctuations. This leads to thermal deformation of the machine bed, directly causing the ground guideways to have excessive parallelism, reducing the yield rate of guideway processing, and diminishing the effectiveness of the three-sided profile grinding machine, thus failing to meet people's needs. Summary of the Invention

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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1 Please see Figures 1-8 This application provides a three-sided forming grinding machine for guide rail machining, including a bed 1 and a machining structure 2 disposed on the outer side of the bed 1. The bed 1 is provided with a machining table 3 that cooperates with the machining structure 2. The machining table 3 can position the guide rail. The machining structure 2 includes a column, a crossbeam, a feed slide disposed on the crossbeam, and a grinding head assembly disposed on the feed slide and used to machine the guide rail. The grinding head assembly performs three-sided grinding of the guide rail in cooperation with the feed slide. The bed 1 is provided with a cooling mechanism, which includes symmetrical pre-cooling... The cooling pipe 4 is located inside the bed 1; the filter box 5 is located outside the bed 1 and connected to the water inlet of the cooling pipe 4; and the tee fitting 6 is detachably installed on the outer wall of the filter box 5. Water guide pipes 7 are symmetrically installed on the tee fitting 6, and control valves 8 are installed on the water guide pipes 7. A filter cylinder 9 is located at the other end of the water guide pipe 7. The filter cylinder 9 contains several first filter screens. The filter cylinder 9 is connected to a circulating water tank via a connecting pipe. The circulating water tank is connected to the water outlet of the cooling pipe 4. The circulating water tank contains a system for introducing constant-temperature coolant. The second filter screen performs initial filtration, thereby cooling the bed 1, actively equalizing the temperature of the bed 1, eliminating internal temperature differences, and offsetting the effects of ambient temperature changes. The cooling mechanism also includes a filter assembly set in the filter box 5. The filter assembly includes a rotating magnetic cylinder 10 rotatably set inside the filter box 5, rotating blocks 11 set at both ends of the rotating magnetic cylinder 10 and rotatably connected to the filter box 5, and a first drive motor 12 set outside the filter box 5 and controlling the rotation of the rotating blocks 11. The inner wall of the filter box 5 is provided with a magnetic roller 13 coaxially connected to the rotating magnetic cylinder 10 and the rotating blocks 11. The magnetic roller 13 is provided with a permanent magnet 14. The vertical cross-section of the permanent magnet 14 is arc-shaped. The permanent magnet 14 is set inside the lower side of the rotating magnetic cylinder 10. Two through holes are symmetrically opened on the filter box 5, so that the constant temperature coolant after filtration by the filter cylinder 9 enters the filter box 5 through the three-way fitting 6. The rotating magnetic cylinder 10, the magnetic roller 13, and the permanent magnet 14 work together to adsorb and clean the fine iron filings in the constant temperature coolant, solving the problem of fine iron filings generated by the machining structure 2.

[0033] In this embodiment, the guide rail is positioned on the machining table 3, the machining structure 2 is started, and the machining table 3 is controlled to move on the bed 1 so that the grinding head assembly performs three-sided grinding on the guide rail. The second filter screen filters the constant temperature coolant entering the circulating water tank. The circulating water tank controls the constant temperature coolant to be introduced into the filter cylinder 9, so that the first filter screen filters the constant temperature coolant again. The filtered constant temperature coolant enters the filter box 5 through the water guide pipe 7 and the three-way fitting 6. The first drive motor 12 is started, which drives the rotating block 11 to rotate, so that the rotating block 11 drives the rotating magnetic cylinder 10 to rotate. The magnetic roller 13 and the permanent magnet 14 work together to attract the fine iron filings in the constant temperature coolant to the rotating magnetic cylinder 10, so that the rotating magnetic cylinder 10 cleans the fine iron filings, and the cleaned constant temperature coolant enters the cooling pipe 4, so that the cooling pipe 4 equalizes the temperature of the bed 1.

[0034] The cooling mechanism of this invention also includes a cleaning component disposed on the filter box 5 to process iron filings on the rotating magnetic cylinder 10. The cleaning component includes a fixing strip 15 disposed on the upper part of the filter box 5 and several high-pressure nozzles 16 disposed on the fixing strip 15. Air pipes are connected to the high-pressure nozzles 16, one end of which extends out of the filter box 5 and is connected to an air source. The high-pressure nozzles 16 can reverse-flushing the iron filings attached to the upper outer surface of the rotating magnetic cylinder 10, which facilitates the cleaning of iron filings on the rotating magnetic cylinder 10. The cleaning component also includes a vacuum nozzle 17 disposed on the filter box 5 and suction components 18 symmetrically disposed on the upper end of the vacuum nozzle 17. The lower end of the vacuum nozzle 17 is disposed above the rotating magnetic cylinder 10 and works in conjunction with the high-pressure nozzles 16 to perform negative pressure suction of the loosened and floated iron filings.

[0035] In this embodiment, the high-pressure nozzle 16 is controlled to spray air onto the rotating magnetic cylinder 10, so that the iron filings attached to the upper end face of the rotating magnetic cylinder 10 are loosened, causing the suction component 18 to generate negative pressure, and causing the vacuum nozzle 17 to suck up the loosened and floated iron filings under negative pressure, thereby cleaning the rotating magnetic cylinder 10.

[0036] The cleaning assembly of this invention also includes a cleaning box 19 disposed on the upper surface of the filter box 5 and a negative pressure device 20 disposed on one side of the cleaning box 19. One end of the suction member 18 extends into the cleaning box 19, and the connection between the suction member 18 and the cleaning box 19 is sealed. A partition 21 that works with the suction member 18 is installed inside the cleaning box 19. The partition 21 divides the internal space of the cleaning box 19 into an adsorption chamber and a collection chamber. The outlet of the suction member 18 is disposed in the adsorption chamber. Collection boxes 51 that extend into the collection chamber are symmetrically disposed on the cleaning box 19. The collection boxes 51 can collect the cleaned iron filings, and the collection boxes 51 are sealed to the cleaning box 19.

[0037] In this embodiment, the negative pressure device 20 is activated, which generates negative pressure in the adsorption chamber and the suction component 18, so that the vacuum nozzle 17 sucks up the loosened and floated iron filings under negative pressure and draws the iron filings into the cleaning box 19.

[0038] The cleaning assembly of the present invention also includes a partition 22 symmetrically arranged inside the adsorption chamber and a support 23 symmetrically arranged on the upper surface of the separator 21. The partition 22 divides the adsorption chamber into two areas. The upper surface of the support 23 is connected to the inner top surface of the cleaning box 19. The support 23 is arranged on one side of the partition 22. A filter plate 24 is installed between the two support 23s. The filter plate 24 can filter iron filings.

[0039] In this embodiment, when the vacuum nozzle 17 sucks the loosened and floated iron filings into the cleaning box 19, the filter plate 24 filters the iron filings.

[0040] The cleaning assembly of the present invention further includes a scraper 25 movably mounted on the support base 23 for cleaning the filter plate 24, and a first screw drive structure 26 symmetrically arranged inside the support base 23 for controlling the scraper 25 to move up and down. The top end of the first screw drive structure 26 is provided with a rotating rod 27 extending into the cleaning box 19. The inside of the cleaning box 19 is provided with a synchronous belt structure 28 coaxially connected to the rotating rod 27. The cleaning box 19 is provided with a synchronous groove that matches the synchronous belt structure 28. The upper end of the cleaning box 19 is provided with a second drive motor 29 for controlling the synchronous belt structure 28 to work.

[0041] In this embodiment, when the negative pressure device 20 stops working, the second drive motor 29 is started, which drives the synchronous belt structure 28 to work. The synchronous belt structure 28 drives the rotating rod 27 to rotate, which in turn drives the first lead screw transmission structure 26 to work. The first lead screw transmission structure 26 drives the scraper 25 to move, so that the scraper 25 cleans off the iron filings adhering to the filter plate 24 and causes the cleaned iron filings to fall into the collection chamber, so that the collection box 51 collects the iron filings.

[0042] In this invention, both ends of the scraper 25 are provided with fixing blocks 30, and the first lead screw transmission structure 26 is provided with an installation strip 31 that is aligned and connected with the fixing blocks 30. One end of the installation strip 31 is provided with a moving block 32 that fits against the inner side wall of the support base 23. The moving block 32 is vertically mounted with a moving strip 33 that is connected to the first lead screw transmission structure 26.

[0043] In this embodiment, the second drive motor 29 is started, and the synchronous belt structure 28 drives the first lead screw transmission structure 26 to work through the rotating rod 27. This causes the first lead screw transmission structure 26 to drive the moving bar 33 to move, the moving bar 33 to drive the moving block 32 to move, the moving block 32 to drive the mounting bar 31 to move, the mounting bar 31 to drive the fixed block 30 to move, and the fixed block 30 to drive the scraper 25 to move.

[0044] Example 2 Based on Example 1, referring to Figures 6-9This is the second embodiment of the present invention, wherein the separator 21 is provided with a discharge trough 34 that connects the adsorption chamber and the collection chamber, and the separator 21 is provided with a sealing component for sealing the discharge trough 34.

[0045] In this embodiment, when the second drive motor 29 starts, the discharge chute 34 is opened, and when the second drive motor 29 stops, the discharge chute 34 is blocked.

[0046] The sealing assembly of this invention includes a sealing plate 35 movably disposed in the partition 21 to seal the discharge trough 34, and a second lead screw transmission structure 36 disposed inside the partition 21 to control the horizontal movement of the sealing plate 35. The partition 21 has a sealing groove that fits against the sealing plate 35. A first bevel gear structure 37 is coaxially mounted on the other end of the second lead screw transmission structure 36. The first bevel gear structure 37 is connected to a second bevel gear structure 38 via a first transmission rod. The bottom end of the support base 23 has a protrusion 39 extending into the discharge trough 34. The bottom end of the first lead screw drive structure 26 extends into the protrusion 39. The bottom end of the first lead screw drive structure 26 is provided with a third bevel gear structure 40. The third bevel gear structure 40 is coaxially connected to the second bevel gear structure 38 through the second transmission rod. When the first lead screw drive structure 26 is working, the third bevel gear structure 40, the second bevel gear structure 38 and the first bevel gear structure 37 cooperate to control the two second lead screw drive structures 36 to work synchronously, so that the second lead screw drive structures 36 control the sealing plate 35 to move, opening or closing the discharge chute 34.

[0047] In this embodiment, when the first lead screw transmission structure 26 is working, it drives the third bevel gear structure 40 to rotate, which in turn drives the second transmission rod to rotate. The second transmission rod then drives the second bevel gear structure 38 to rotate, which in turn drives the first transmission rod to rotate. The first transmission rod then drives the first bevel gear structure 37 to rotate, which in turn drives the second lead screw transmission structure 36 to work. This causes the second lead screw transmission structure 36 to move the sealing plate 35 horizontally, allowing the sealing plate 35 to either block or open the discharge chute 34.

[0048] Example 3 Based on Example 2, referring to Figures 7-11This is the third embodiment of the present invention. In this embodiment, the support base 23 is provided with a movable groove that fits with the movable strip 33. The support base 23 is provided with a sealing assembly that works in conjunction with the movable groove. The sealing assembly includes elastic sealing strips 41 symmetrically arranged on the rear side of the movable block 32 and several sealing blocks 42 movably arranged inside the support base 23 to seal the movable groove. The elastic sealing strips 41 are fitted and connected to the movable groove. The two elastic sealing strips 41 are respectively fitted to the upper and lower end faces of the movable strip 33, so that the several sealing blocks 42 and the elastic sealing strips 41 work together to seal the movable groove.

[0049] In this embodiment, when the moving block 32 moves, it causes the elastic sealing strip 41 and the sealing block 42 to move, so that the sealing block 42 controls the movement of the sealing block 42 during the movement, and the moving block 32, the elastic sealing strip 41 and the sealing block 42 cooperate to seal the moving groove in real time.

[0050] The sealing assembly of the present invention further includes a guide strip 43 disposed on one side of the sealing block 42 and a first groove formed on the guide strip 43. A movable rack 44 is installed in the first groove. A movable gear 45 that meshes with the movable rack 44 is rotatably disposed inside the support base 23. A drive groove that fits with the guide strip 43 is formed on the support base 23. A sealing groove that fits with the sealing block 42 is formed on the support base 23. The guide strip 43 can limit and guide the sealing block 42. When the movable gear 45 rotates, the guide strip 43 controls the sealing block 42 to move through the cooperation of the movable gear 45 and the movable rack 44, thereby sealing or opening the movable groove.

[0051] In this embodiment, when the control moving gear 45 rotates, the moving gear 45 meshes with the moving rack 44, causing the moving gear 45 to drive the moving rack 44 to move, the moving rack 44 to drive the guide bar 43 to move, and the guide bar 43 to drive the sealing block 42 to move horizontally, so that the sealing block 42 seals or opens the moving groove.

[0052] The sealing assembly of this invention also includes a first drive bar 46 vertically disposed on one side of the moving bar 33 and a second groove formed on the first drive bar 46. A main rack 47 is installed in the second groove. A first drive groove matching the first drive bar 46 is formed on the support base 23. A main gear 48 is coaxially connected to one side of the moving gear 45. The diameter of the main gear 48 is smaller than the diameter of the moving gear 45. The main rack 47 can mesh with the main gear 48. When the moving bar 33 drives the first drive bar 46 to move, the main rack 47 meshes with the main gear 48. When the first drive bar 46 continues to move, the main gear 48 controls the movement of the sealing block 42 through the cooperation of the moving gear 45, the moving rack 44 and the guide bar 43. When the main rack 47 separates from the main gear 48, the moving gear 45 and the moving rack 44 cooperate to move the sealing block 42 into the sealing groove.

[0053] In this embodiment, when the moving bar 33 moves, it causes the first drive bar 46 to move, and the first drive bar 46 causes the main rack 47 to move. When the main rack 47 meshes with the main gear 48, the main rack 47 causes the main gear 48 to move, and the main gear 48 causes the moving gear 45 to rotate. The moving gear 45 and the moving rack 44 cooperate to drive the guide bar 43 to move, and the guide bar 43 causes the sealing block 42 to move. The sealing block 42 opens the moving groove, allowing the moving bar 33 to pass through.

[0054] The sealing assembly of this invention also includes a connecting strip 49 vertically disposed on one side of the moving strip 33 and a second driving strip 50 fixedly disposed on the connecting strip 49. The support base 23 has a connecting groove that matches the connecting strip 49 and a second driving groove that matches the second driving strip 50. The second driving strip 50 has a third groove that aligns with the second groove. The main rack 47 is disposed in the third groove. The second driving strip 50 and the third groove are disposed on the other side of the main gear 48, so that the main rack 47 on the second driving strip 50 can control the sealing block 42 to move through the main gear 48. When the main rack 47 on the second driving strip 50 is separated from the main gear 48, the moving gear 45 and the moving rack 44 cooperate to move the sealing block 42 from the sealing groove to the moving groove, so that the sealing block 42 seals the moving groove at that location.

[0055] In this embodiment, when the moving bar 33 continues to move, it causes the connecting bar 49 to move, and the connecting bar 49 causes the second driving bar 50 to move, which in turn causes the main rack 47 to move. When the main rack 47 meshes with the main gear 48, the main gear 48 causes the moving gear 45 to rotate, and the moving gear 45 and the moving rack 44 work together to move the guide bar 43, which in turn causes the sealing block 42 to move, and the sealing block 42 seals the moving groove.
