Description

Technical Field

[0001] This invention belongs to the field of machining equipment and relates to an environmentally friendly multi-functional grinding machine for processing metal profiles. Background Technology

[0002] A grinding machine is a machine tool that uses grinding wheels to grind the surface of a workpiece. A grinding machine mainly consists of a spindle, bed, cantilever beam, tool holder support, worktable, rotary table, cross slide, lifting table, and base. The main classifications of grinding machines are cylindrical grinding machines, internal grinding machines, and surface grinding machines. Among these, surface grinding machines are most widely used in workshops processing profiles.

[0003] Currently, most grinding machines operate in completely open environments. Since the grinding dust is much finer than turning dust, even though spraying coolant during processing can reduce dust, the pollution in the workshop is still greater than other processing methods, and it also poses certain hazards to the grinders. Furthermore, existing surface grinders generally have only one machining axis and a relatively limited machining range. For workpieces with flat or inclined surfaces, such as dovetail grooves, only the straight sections of the groove can be ground. Finishing the dovetail grooves requires additional equipment or manual processing by workers; the former is costly, while the latter is inefficient. Secondly, the sludge and grime formed on the workpiece surface during grinding can be washed away by the sprayed coolant if the workpiece is small. However, for larger workpieces, sludge and grime may accumulate in other areas besides the currently being processed, easily being carried up by the grinding wheel and thrown onto other parts. Even with a grinding wheel guard, the protection range is very limited. Summary of the Invention

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0034] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0035] Examples, such as Figures 1-14As shown, the present invention provides an environmentally friendly multifunctional grinding machine for metal profile processing, including a surface grinder 1. The surface grinder 1 includes a spindle box 11, and a spindle grinding wheel 12 is provided at the power output end of the spindle box 11. The surface grinder 1 also includes an electromagnetic chuck for adsorbing workpieces, an X-axis drive mechanism for driving the electromagnetic chuck to reciprocate along the X-axis, a Y-axis drive mechanism for driving the slide seat supporting the electromagnetic chuck to reciprocate along the Y-axis, and a Z-axis reciprocating drive mechanism for driving the spindle box 11 to lift and lower. Based on this, the surface grinder 1 provided by the present invention is provided with a protective enclosure 2 on its outer side, and a sliding double door 3 is provided on the front side of the protective enclosure 2. A connecting seat 4 is provided on one side of the spindle box 11, and a secondary spindle device 5 is provided on the connecting seat 4. The secondary spindle device 5 includes a secondary spindle box 51. A secondary spindle motor 52 and a secondary spindle grinding wheel 53 are respectively provided at the power input end and power output end of the secondary spindle box 51. The rotation center of the secondary spindle grinding wheel 53 intersects the rotation center of the spindle grinding wheel 12 in a non-plane manner. A vibration pressure suction device 6 connected to the spindle box 11 is provided below the spindle grinding wheel 12. The vibration source of the vibration pressure suction device 6 is the workpiece and the spindle box 11. The pressure suction surface of the vibration pressure suction device 6 faces the grinding surface of the spindle grinding wheel 12.

[0036] Specifically, the protective enclosure 2 is distributed around the perimeter of the surface grinder 1. The top of the protective enclosure 2 can be either closed or open. If closed, lighting equipment needs to be installed on top; if open, the workshop's existing lighting equipment can be used to illuminate the grinding area. The bottom of the protective enclosure 2 is supported by a bracket made of welded square tubing. Guide rails are provided on the inner side of the front of the protective enclosure 2 for installing the sliding double door 3. By installing the protective enclosure 2 and the sliding double door 3 around the working area of ​​the surface grinder 1, the environmental friendliness and safety of this equipment during workpiece processing are improved.

[0037] This invention adopts a main and auxiliary dual-working-axis design. The main shaft grinding wheel 12 is used for surface grinding, while the auxiliary shaft grinding wheel 53 is a cup-shaped grinding wheel used for inclined surface grinding, such as grinding the dovetail groove of the slide. Therefore, it integrates both surface grinding and inclined surface grinding functions, which can be switched according to processing requirements. It has strong processing capabilities and helps to reduce equipment costs in the workshop.

[0038] The vibration suction device 6 provided by this invention is adapted to the surface grinding function. It is a non-powered structure, using the workpiece and the spindle box 11 as vibration sources. The vibration of the workpiece and the spindle box 11 during the grinding process causes frequent compression of its own suction gap 67. The lowest level of the vibration suction device 6 is slightly higher than the lowest grinding surface of the spindle grinding wheel 12. The grinding dust and the coolant sprayed from the coolant pipe form dust. Except for the dust that is washed away, most of the dust remaining on the workpiece surface is located around the current grinding surface. This dust is squeezed into the interior of the vibration suction device 6 by the pressure of the suction gap 67, and excess dust is recovered in time to avoid the continuous rotation of the spindle grinding wheel 12 carrying up a large amount of dust. For the dust that is not recovered temporarily, the main board 61 closely follows the spindle grinding wheel 12 and provides a splash-proof function. During the relative movement between the main board 61 and the workpiece, the dust provides a certain polishing and cooling effect on the workpiece surface, which is beneficial to improving the quality of grinding to a certain extent. In addition, after adopting the vibration pressure suction device 6, the grinding wheel housing of the main shaft grinding wheel 12 does not need to be installed, thus reducing the workload of cleaning and frequently disassembling and assembling the grinding wheel housing.

[0039] To improve the suction performance of the vibration suction device 6, the vibration suction device 6 provided by the present invention includes a main board 61. The top of the main board 61 is provided with a wire brush 62 facing the wheel surface of the spindle grinding wheel 12. The main board 61 is provided with a grinding passage 63 that corresponds vertically to the spindle grinding wheel 12. The bottom of the main board 61 is provided with at least two mounting grooves 64. A horizontal shaft 65 is provided in the mounting groove 64. A vibration plate 66 is provided on the horizontal shaft 65. A suction gap 67 is provided at the center of the vibration plate 66. Multiple suction ports 68 are provided on both sides of the suction gap 67. The wire brush 62 is used to brush the powder and sludge carried by the spindle grinding wheel 12 down into the working range of the vibration suction device 6, and to prevent the powder and sludge from adhering to the grinding surface over a large area, thus affecting the grinding efficiency of the spindle grinding wheel 12. The grinding passage 63 provides a sufficient working opening for the spindle grinding wheel 12, and the coolant can enter the grinding working surface along the cut surface of the spindle grinding wheel 12. While the main plate 61 moves relative to the workpiece, it covers the surrounding area through which the grinding passes, providing a shield for the powder and sludge to be carried up. At the same time, the mounting groove 64 provides a concealed mounting base for the horizontal shaft 65 and the vibrating plate 66, and limits the maximum vibration amplitude of the vibrating plate 66, so that the vibrating plate 66 can obtain effective vibration potential energy at a position infinitely close to the workpiece, thereby converting it into its own vibration source. The suction gap 67 changes accordingly, and the pressure generated by the change forces the excess powder and sludge to be squeezed into / sucked into the vibration suction device 6 from the suction port 68, completing the recycling.

[0040] Furthermore, the vibrating plate 66 provided by the present invention has a left-right symmetrical structure. The vibrating plate 66 includes two clamping sections 661 that cooperate with the horizontal shaft 65. The horizontal shaft 65 has dovetail grooves on both sides. The clamping section 661 is R-shaped and its R-shaped head engages with the groove. One end of the clamping section 661 is free and faces upward, while the other end of the clamping section 661 extends downward at an angle. The bottom of the clamping section 661, i.e., the other end of the clamping section 661, is provided with a vibrating section 662. The vibrating section 662 has an acute angle structure and its side facing the workpiece is an upward inclined surface. A ridge section 663 is provided at a position directly below the horizontal shaft 65 on the inclined surface. The top of the ridge section 663 is in dynamic contact with the lower surface of the horizontal shaft 65. The inclined surface of the vibrating section 662 allows a portion of the grinding powder to enter its vertical coverage area and provides a certain flow guide for the grinding powder to be sucked into the vibrating suction device 6. The ridge section 663 is slightly lower than the horizontal axis 65 in its natural state. The horizontal axis 65 serves as the limit and highest point of the ridge section 663. While the clamping section 661 and the vibrating section 662 vibrate, the ridge section 663 can impact the bottom of the horizontal axis 65. The impact potential energy causes the ridge section 663 to provide a reverse vibration tendency to the vibrating section 662 and the clamping section 661. In addition, the vibration effect that is unavoidable during the grinding process can make the vibrating plate 66 reciprocate, thereby achieving the function of intermittently recovering the grinding powder. This ensures that the amount of grinding powder in the grinding range is kept at a balanced level, neither too much nor too little. The grinding powder kept at a balanced level can play a certain role in cooling and polishing, which is conducive to improving the grinding quality of the workpiece by this equipment.

[0041] To facilitate real-time processing of powdered mud, the vibrating section 662 provided in this invention is internally equipped with a compression groove 69, and the compression groove 69 is internally equipped with wire mesh filler (not shown in the figure). Both the wire mesh filler and the compression groove 69 have the ability to deform with the vibrating section 662. Simultaneously, the wire mesh filler provides effective attachment points for the powdered mud, and the filling volume of the wire mesh filler matches the acute angle of the vibrating section 662. This allows the powdered mud sucked into the vibrating suction device 6 to maintain a certain amount, and the dynamic retention level will not exceed the lowest position of the suction inlet 68. One end of the compression groove 69 is open and faces the power input direction of the main shaft box 11. The main board 61 is provided with a discharge chute 610 near the open end. In this way, the powder and sludge trapped by the wire mesh packing can be squeezed out towards both ends of the wire mesh packing while being compressed by the compression groove 69 and the wire mesh packing. The gap between one end of the compression groove 69 and the groove wall of the mounting groove 64 is small, and the extrusion resistance is large. The opening and the connection position of the discharge groove 610 are provided with teeth. These teeth allow the powder and sludge squeezed out by the compression groove 69 and the wire mesh packing to fall along the vertical direction of the discharge groove 610, and can fall to a position outside the workpiece or the electromagnetic chuck of the surface grinder 1. The discharged powder and sludge is collected, discharged and processed by other devices.

[0042] To improve the practicality of the counterspindle housing 51, the counterspindle housing 51 provided by this invention is connected to the main spindle housing 11 in a transmission manner. The main spindle housing 11 is internally equipped with a transmission mechanism 7, which controls the rotation of the main spindle grinding wheel 12 and the pitch movement of the counterspindle housing 51 through an electromagnetic clutch action. For the pitch adjustment of the counterspindle housing 51, no additional power source is used; instead, an effective transmission structure is provided based on the existing power source to achieve the adjustment purpose.

[0043] Specifically, the transmission mechanism 7 provided by the present invention includes a main shaft 71. A main shaft drive gear set 715 is provided at the power input end of the main shaft 71. The main shaft drive gear set 715 includes a spur gear set 7151 that is drively connected to the main shaft 71. The spur gear set 7151 includes a large spur gear and a small spur gear. A bevel gear set 7152 is coaxially connected to the small spur gear. The bevel gear set 7152 includes a large bevel gear and a small bevel gear. A steering angle shaft 7153 is coaxially connected to the small bevel gear set 7152. The steering angle shaft 7153 is intersected with the lifting transmission shaft of the main spindle box 11. The two ends of the steering angle shaft 7153 are rotatably supported on the inner wall of the main spindle box 11. A reduction gear set 7154 is provided at the rear end of the steering angle shaft 7153. The reduction gear set 7154 is connected to the main spindle motor 716. At least three levels of speed reduction are achieved from the main spindle motor 716 to the electromagnetic clutch 72, and the lifting transmission path of the main spindle box 11 is reasonably avoided, which can ensure that the main spindle 71 has stable power input conditions.

[0044] Furthermore, the main shaft 71 provided by the present invention is located at the center of the electromagnetic clutch 72. An active bevel gear 73 is provided on the outer periphery of the active side of the electromagnetic clutch 72. A pitch adjustment bevel gear 74 is provided on the transmission side of the active bevel gear 73. A gear shaft 75 is coaxially provided on the pitch adjustment bevel gear 74. A brake rod 76 is provided on the axial surface of the gear shaft 75. A brake inclined surface 77 is provided at one end of the brake rod 76. The brake inclined surface 77 is in dynamic contact with the driven end of the electromagnetic clutch 72. A pitch adjustment spur gear 78 is provided on the tooth surface of the gear shaft 75 and meshes with it. An adjustment shaft 79 connected to the auxiliary shaft box 51 is provided at the center of the pitch adjustment spur gear 78. In this invention, the driving side of the electromagnetic clutch 72 is a constantly rotating structure, and its power is switched on and off with the driven side by means of energizing. The driving side of the electromagnetic clutch 72 serves as the shaft of the driving bevel gear 73, and the driven side serves as the axial drive structure of the brake lever 76. When the electromagnetic clutch 72 is energized, the driven side and the driving side are effectively connected, and the driven side rotates synchronously with the main grinding wheel 12, thereby achieving the corresponding surface grinding function. When the electromagnetic clutch 72 is de-energized, the driven side disconnects from the driving side under the action of the elastic structure inside the electromagnetic clutch 72. The power connection on the driven side generates a certain axial displacement, which also serves as the axial displacement of the brake lever 76. This causes the pitch adjustment bevel gear 74 to mesh with the driving bevel gear 73, and the gear shaft 75 to mesh with the pitch adjustment spur gear 78, thus establishing a transmission connection between the adjustment shaft 79 and the main shaft 71. Switching to a low-speed gear to start the main shaft motor 716, the main shaft motor 716 reduces speed through multiple stages, allowing the sub-shaft box 51 to obtain a certain adjustment angle. Therefore, manual disassembly and assembly are not required, which is beneficial to improving the motor matching performance of the sub-shaft box 51 and the equipment, and to improving the overall utilization rate of the equipment.

[0045] To improve the reliability of the pitch adjustment action of the counterspindle housing 51, the brake lever 76 provided by the present invention is provided with a first guide rod 710 and a second guide rod 711 spanning both sides of the gear shaft 75 and the pitch adjustment spur gear 78 on the side facing the connecting seat 4. The first guide rod 710 cooperates with the guide groove 41 provided inside the connecting seat 4. The outer side of the connecting seat 4 is provided with a guide hole 42 that cooperates with the second guide rod 711 and a reset hole that is radially connected to the guide hole 42. The second guide rod 711 is provided with a reset pull rod 712 that cooperates with the reset hole. The reset pull rod 712 is provided with a reset spring 713. The end of the reset pull rod 712 and the end of the second guide rod 711 are both provided with limit plugs 714. The mating nodes of the first guide rod 710 and the guide groove 41, and the second guide rod 711 and the guide hole 42, provide a certain support span for the brake rod 76, which helps to ensure the stability and reliability of its translation. At the same time, the two ends of the return spring 713 will achieve dynamic balance during the translation of the brake rod 76. Especially when the electromagnetic clutch 72 is energized, the return lever 712 is pulled by the return spring 713 to drive the brake rod 76 to return to its original position. This ensures that the brake rod 76 can immediately enter the working state after the coil of the electromagnetic clutch 72 is de-energized, which is beneficial to the system's control over the pitch adjustment of the countershaft box 51.

[0046] To ensure the quality of grinding operations with this equipment, from a cooling perspective, the top of the connecting seat 4 provided by this invention is equipped with a coolant spraying assembly 8. The coolant spraying assembly 8 includes a water distributor 81, on which is provided a first coolant pipe 82 facing the main spindle grinding wheel 12 and two second coolant pipes 83 facing the counterspindle grinding wheel 53. The coolant sprayed from the first coolant pipe 82 is used to cool the main spindle grinding wheel 12 and the workpiece surface; the coolant sprayed from the second coolant pipes 83 is used to cool the cup-shaped surface of the counterspindle grinding wheel 53 and the dovetail groove surface of the workpiece, thereby meeting the grinding requirements. To ensure the synchronization of the pitch adjustment between the second coolant pipe 83 and the sub-shaft housing 51, the present invention provides a radial seat on the side of the sub-shaft housing 51 that mates with the connecting seat 4. A connecting plate 85 is provided on the side of the radial seat, and a perforated plate 84 is provided on the connecting plate 85. The perforated plate 84 provides multiple support holes that can cooperate with the second coolant pipe 83. The second coolant pipe 83 has a certain deformation capacity. During the process of adjusting the pitch angle of the sub-shaft housing 51 by the transmission mechanism 7, the second coolant pipe 83 can be adjusted synchronously to reduce manual intervention and improve the maneuverability of the equipment.

[0047] To facilitate centralized treatment of grinding waste liquid, the surface grinder 1 provided by the present invention is equipped with a sludge hopper 9 inside. A rear drawer opening 13 for moving the sludge hopper is provided on the rear side of the surface grinder 1. The sludge hopper 9 is connected to the support structure of the electromagnetic chuck of the surface grinder 1. Water spray pipes for spraying cleaning media are provided on both sides of the surface grinder 1. Connecting the sludge hopper 9 to the support structure of the electromagnetic chuck allows the waste liquid to be discharged from the sludge hopper, thereby cleaning the processing environment inside the equipment in a timely manner and avoiding large-scale accumulation of powder and sludge.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
