Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, and in particular to a surface grinding machine. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. It is a component used to transmit or receive electromagnetic waves in radio equipment. The antenna carrier is an important component of the carrier antenna, and the antenna carrier needs to be polished during the processing.

[0003] A surface grinder is a type of grinder, which mainly uses a grinding wheel to rotate and grind the workpiece so that it can achieve the required flatness. The antenna carrier is generally ground by a surface grinder. The grinding wheel grinds the antenna carrier. Part of the debris generated during the grinding process adheres to the grinding surface of the grinding wheel, causing the grinding wheel to be blocked. The grinding wheel blockage will lead to increased grinding force and increased cutting temperature, thereby affecting the processing accuracy, reducing the surface quality, and may cause the workpiece to burn. In order to improve the grinding effect of the antenna carrier, the grinding wheel is flushed and cooled by coolant to separate the debris from the grinding wheel. When the grinding wheel is flushed with coolant, due to the long grinding time, the grinding wheel needs to be continuously cooled and flushed with coolant.

[0032] Reference Figure 4-5 The liquid storage mechanism 13 includes a liquid storage box 131, which is fixedly connected to the upper end of the movable frame 4.

[0034] Working principle:

[0035] The antenna carrier is fixed on the movable platform 2, the handle 143 drives the second threaded rod 142 to rotate, the second threaded rod 142 rotates and moves toward the movable frame 4, the second threaded rod 142 drives the connecting plate 141 to move, the connecting plate 141 drives the second connecting tube 10 to move, the second connecting tube 10 slides on the first connecting tube 9, and the second connecting tube 10 also drives the open box 11 to move, so that the open box 11 matches the open opening of the sanding wheel 7;

[0036] After the electric telescopic rod 35 is powered on and started, it drives the movable plate 36 to move in the horizontal direction. The movable plate 36 moves smoothly under the guidance of the second open box 32. The movable plate 36 drives the movable frame 4 to move. The movable frame 4 drives the driving machine 6 to move through the fixed frame 5. The driving machine 6 drives the sanding wheel 7 to move. When the sanding wheel 7 moves to the top of the grinding area of ​​the antenna carrier plate, the electric telescopic rod 35 is self-locking. After the servo motor 33 is powered on and started, it drives the first threaded rod 34 to rotate clockwise for a set number of circles. After the first threaded rod 34 rotates, the second open box 32 moves downward. The second open box 32 moves smoothly under the guidance of the first open box 31. The second open box 32 drives the movable plate 36 to move downward. The movable plate 36 drives the movable frame 4 to move. The movable frame 4 drives the driving machine 6 to move through the fixed frame 5. The driving machine 6 drives the sanding wheel 7 to move downward for a set distance and then contacts with the grinding area of ​​the antenna carrier plate, so as to accurately adjust the position of the sanding wheel 7.

[0037] After the driving machine 6 is started, it drives the sanding wheel 7 to rotate. After the sanding wheel 7 rotates, the antenna carrier plate is polished. During the polishing process, the movable table 2 drives the antenna carrier plate to reciprocate in the horizontal direction. During the movement of the antenna carrier plate, it contacts the rotating sanding wheel 7. The sanding wheel 7 polishes the antenna carrier plate. At the same time, the pump 8 is powered on and started. After the pump 8 is started, the coolant in the liquid storage tank 131 is pumped out through the first conduit, and the pumped coolant is introduced into the first connecting pipe 9. The coolant in the first connecting pipe 9 is introduced into the second connecting pipe 10. Since the outlet of the second connecting pipe 10 is facing the sanding wheel 10, the coolant in the first connecting pipe 9 is introduced into the second connecting pipe 10. The grinding wheel 7 is tilted downward, and the coolant in the second connecting pipe 10 contacts the rotating sanding wheel 7 after being released from the pipe mouth, so as to clean and cool the grinding surface of the sanding wheel 7, so that the debris on the grinding surface of the sanding wheel 7 is separated from the sanding wheel 7. The open box 11 collects the coolant after cleaning the sanding wheel 7, and limits the collection of the coolant splashed by contacting the sanding wheel 7. The cleaned debris and coolant fall into the open box 11. The sanding wheel 7 is in continuous contact with the coolant in the open box 11 during rotation, so that the debris on the grinding surface of the sanding wheel 7 is effectively separated.

[0038] The debris and coolant in the open box 11 are introduced into the liquid storage tank 131 through the third connecting pipe 12 and the third connecting pipe 12. The introduced debris and coolant fall on the filter 132. The filter 132 filters the debris in the coolant. The filtered coolant falls on the bottom of the liquid storage tank 131 and is reused. The coolant circulates in the liquid storage tank 131, the first connecting pipe 9, the second connecting pipe 10, the open box 11 and the third connecting pipe 12. The sanding wheel 7 is in continuous contact with the coolant in the open box 11 during the grinding of the antenna carrier. The coolant cleans the debris on the sanding wheel 7 to prevent the debris from clogging the sanding wheel. The open box 11 blocks and limits the splashing coolant, and the cleaned coolant falls into the open box 11 to prevent the cleaned coolant from falling on the grinder body 1, thereby reducing the waste of coolant.

[0039] Embodiment 2: When the coolant in the open box 11 contacts the grinding surface of the sanding wheel 7 to clean it, since the sanding wheel 7 has a certain rotation speed, the coolant in the open box 11 is in a relatively static state. When the coolant in the static state contacts the grinding surface of the sanding wheel 7 to clean it, it is not convenient to wash out the debris adhered to the grinding surface, thereby reducing the cleaning effect of the grinding surface of the sanding wheel 7. Figure 6-9 As another preferred embodiment of the present invention, on the basis of embodiment 1, an impact mechanism 15 for improving the cleaning effect is connected to the open box 11, and the impact mechanism 15 includes a first rotating roller 151, and the first rotating roller 151 is rotatably connected to the open box 11, and one end of the first rotating roller 151 extends into the open box 11 and is sleeved with a first elastic sealing sleeve 152, and the first elastic sealing sleeve 152 contacts the grinding surface of the sanding wheel 7, and the first elastic sealing sleeve 152 contacts the inner upper end of the open box 11, and the open box 11 is rotatably connected to A second rotating roller 153, the second rotating roller 153 is located below the first rotating roller 151, one end of the second rotating roller 153 extends into the open box 11 and is sleeved with a second elastic sealing sleeve 154, the second elastic sealing sleeve 154 contacts the grinding surface of the sanding wheel 7, the second elastic sealing sleeve 154 contacts the inner bottom end of the open box 11, and a stirring assembly 155 is rotatably connected to the open box 11, one end of the stirring assembly 155 extends into the open box 11, and the stirring assembly 155 is connected to the second rotating roller 153 through a belt transmission member 156;

[0040] Reference Fig. 9 The stirring assembly 155 includes a rotating shaft 1551, which is rotatably connected to the open box 11. One end of the rotating shaft 1551 extends into the open box 11 and is fixedly connected to a fixed tube 1552. A plurality of fan plates 1553 are connected to the fixed tube 1552 at equal intervals along the axis direction.

[0041] Working principle:

[0042] The grinding surface of the sanding wheel 7 is in squeeze contact with the first elastic sealing sleeve 152 and the second elastic sealing sleeve 154. After the sanding wheel 7 rotates, it drives the second elastic sealing sleeve 154 to rotate through friction. The second elastic sealing sleeve 154 drives the second rotating roller 153 to rotate. The second rotating roller 153 drives the rotating shaft 1551 to rotate through the belt transmission member 156. The rotating shaft 1551 drives the fixed tube 1552 to rotate. The fixed tube 1552 drives the plurality of fan plates 1553 to rotate. After the plurality of fan plates 1553 rotate, they stir the coolant in the open box 11. The surging coolant collides with the grinding surface of the rotating sanding wheel 7. The sanding wheels 7 are all in a moving state. After the coolant collides with the sanding wheel 7, a large impact force will be generated. The coolant collides with the grinding surface of the sanding wheel 7 with a large impact force. The impact force generated by the collision acts on the grinding surface of the sanding wheel 7, so that the debris on the grinding surface of the sanding wheel 7 is greatly scoured. After the debris is greatly scoured, it is separated from the grinding surface of the sanding wheel 7, and the separated debris falls into the coolant. The surging coolant collides with the grinding surface of the rotating sanding wheel 7, thereby increasing the scouring force on the grinding surface of the sanding wheel 7, effectively washing off the debris on the grinding surface of the sanding wheel 7, and improving the cleaning effect of the grinding surface of the sanding wheel 7.

[0043] Embodiment 3: After the fan plate 1553 rotates, the coolant in the open box 11 is stirred, and the surging coolant collides with the grinding surface of the rotating sanding wheel 7, causing the debris on the grinding surface of the sanding wheel 7 to fall off. After the debris falls off, the coolant adhering to the grinding surface of the sanding wheel 7 increases. Due to the increase of coolant on the surface of the sanding wheel 7, the coolant on the surface will be thrown out after the sanding wheel 7 rotates, resulting in splashing of coolant. Figure 9-10 As another preferred embodiment of the present invention, on the basis of Embodiment 2, a moisture absorption mechanism 16 for reducing liquid splashing is connected to the open box 11, and the moisture absorption mechanism 16 includes a fixed plate 161, one end of the fixed plate 161 is fixedly connected to the open box 11, and the other end of the fixed plate 161 is connected to a groove frame 162 through a fixing bolt, and a movable groove 163 is provided on the groove frame 162, and a slider 164 is slidably connected to the movable groove 163, and a spring 165 is fixedly connected to the slider 164, and one end of the spring 165 is fixedly connected to the movable groove 163, and a moisture absorption component 166 is rotatably connected to the slider 164, and the moisture absorption component 166 is in contact with the sanding wheel 7;

[0044] Reference Figure 9-10 The moisture absorption component 166 includes a third rotating roller 1661, which is rotatably connected to the slider 164. The third rotating roller 1661 is sleeved with a moisture absorption sleeve 1662, and the moisture absorption sleeve 1662 is in contact with the sanding wheel 7.

[0045] Working principle:

[0046] The fixing plate 161 fixes the groove frame 162, the grinding surface of the sanding wheel 7 squeezes the moisture absorbing sleeve 1662, the moisture absorbing sleeve 1662 drives the third rotating roller 1661 to move, the third rotating roller 1661 drives the slider 164 to move, the slider 164 moves and squeezes the spring 165, the spring 165 generates elastic force after being compressed, the elastic force generated by the spring 165 pushes the slider 164, the slider 164 drives the third rotating roller 1661 to move, the third rotating roller 1661 is squeezed and contacted with the grinding surface of the sanding wheel 7 through the moisture absorbing sleeve 1662;

[0047] After the fan plates 1553 rotate, they stir the coolant in the open box 11, and the surging coolant collides with the grinding surface of the rotating sanding wheel 7. The impact force generated by the collision acts on the grinding surface of the sanding wheel 7, so that the debris on the grinding surface of the sanding wheel 7 is greatly washed away. After being greatly washed away, the debris is separated from the grinding surface of the sanding wheel 7, and the grinding surface of the sanding wheel 7 after cleaning is bonded with the coolant. Because the desiccant sleeve 1662 is in close contact with the grinding surface of the sanding wheel 7 under the elastic force of the spring 165, the desiccant sleeve 1662 is driven to rotate by friction after the sanding wheel 7 rotates. During the rotation of the desiccant sleeve 1662, the coolant on the grinding surface of the sanding wheel 7 is absorbed, thereby reducing the coolant on the grinding surface of the sanding wheel 7, so that no coolant splashes during the rotation of the sanding wheel 7.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
