Description

Technical Field

[0001] This utility model relates to the field of metal engraving machine technology, specifically a water-circulating metal engraving machine. Background Technology

[0002] From a processing principle perspective, engraving is a combination of drilling and milling. Engraving machines have multiple data input modes that can be used as needed. Engraving machines used in metal processing require cooling devices to cool the cutting tools during use.

[0003] According to a published cooling device for a metal engraving machine (publication number: CN220217702U), the above application enables the reuse of water resources, avoids the waste of water resources, and can automatically add water to the cooling water tank, effectively solving the defects of the prior art that cannot reuse cooling water and cannot automatically add water to the tank.

[0004] However, in the aforementioned application, the drainage mesh plate becomes clogged with waste and debris after prolonged use. When it needs to be replaced or cleaned, the equipment must be stopped, which delays processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a water-circulating metal engraving machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-circulating metal engraving machine, comprising an operating table, a drainage hole at the bottom of the operating table, a power spindle mounted on the top of the operating table, a milling cutter mounted at the bottom of the power spindle, and a cooling assembly for circulating wastewater on the surface of the operating table. The cooling assembly includes a water tank, a partition, a base plate, and a filter plate. An adjustment assembly for replacing the filter plate without stopping the equipment is provided on the surface of the water tank. The adjustment assembly includes:

[0007] A fixed base is fixed to the top of the inner wall of the water tank. A water guide groove is hinged to the inner side of the fixed base. A rocker arm is rotatably connected to the surface of the water tank. The output shaft of the rocker arm passes through the water tank and the fixed base, and the output shaft of the rocker arm is fixed to the surface of the water guide groove.

[0008] Preferably, the adjustment assembly further includes a socket on the surface of the rocker arm. A fixed frame is fixed to the top of the water tank. A sliding plate is slidably connected to the inner wall of the fixed frame. A rod is fixed to the surface of the sliding plate. A pull rod is fixed to the top of the sliding plate. A through hole is provided at the top of the fixed frame. A pull rod is fixed to the top of the sliding plate. The top of the pull rod passes through the through hole. A spring is fixed to the surface of the sliding plate. The end of the spring away from the sliding plate is fixed to the inner wall of the fixed frame. The adjustment assembly also includes a limiting component. Rotating the rocker arm can cause the water guide channel to shift, thereby changing the direction of water flow and facilitating subsequent replacement of the filter plate. The rod, in conjunction with the socket, can limit the rocker arm and prevent the water guide channel from reversing, thus affecting the guidance of wastewater.

[0009] Preferably, the limiting component includes a sliding groove, which is formed on the surface of the slide plate. A locking block is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the surface of the locking block, and the end of the second spring away from the locking block is fixed to the inner wall of the sliding groove. A fixed block is fixed inside the fixed frame, and a moving block is slidably connected to the inner wall of the fixed frame. A magnet is fixed to the inner wall of the fixed frame, and the magnet is magnetically connected to the moving block. When the slide plate moves, it drives the locking block to move. When the side of the locking block away from the inclined plane abuts against the side of the fixed block away from the inclined plane, the locking block and the slide plate are limited. Pulling the lever again, when the locking block is located on the side of the moving block away from the fixed block, the first spring drives the slide plate to move the locking block and the moving block synchronously closer to the fixed block. When the surface of the moving block is in contact with the surface of the fixed block, the limitation is released, and the insertion rod is inserted into the insertion hole to limit the rocker arm.

[0010] Preferably, the water tank is fixed to the bottom of the operating table, a partition is fixed to the bottom of the inner wall of the water tank, a water inlet is opened on the surface of the water tank, a water inlet pipe is opened on the top of the water tank, a funnel is connected to the top of the water inlet pipe, the top of the funnel is fixed to the bottom of the operating table, a base plate is fixed to the surface of the partition, a filter plate is placed on the top of the base plate, the end of the filter plate away from the water tank penetrates the water tank, a tee is installed on the back of the water tank, a water pump is connected to the end of the tee away from the water tank, the suction end of the water pump is fixed to the end of the tee away from the water tank, a conduit is fixed to the suction end of the water pump, the end of the conduit away from the water pump penetrates the operating table, and a nozzle is fixed to the end of the conduit away from the water pump. When the water pump is turned on, cooling water is sprayed out from the nozzle through the tee and the conduit for cooling. The cooled wastewater re-enters the water tank through the leak, the funnel, and the water inlet pipe, flows into the water guide channel for guidance, is filtered by the filter plate, and is pumped out again for cooling.

[0011] Preferably, an electric push rod is fixed to the inner wall of the operating table, and a clamping plate is fixed to the output end of the electric push rod to facilitate clamping of the workpiece and prevent displacement during engraving.

[0012] Preferably, the bottom plate and filter plate are provided in two sets, and the two sets of bottom plates and filter plates are symmetrically arranged with the center line of the water tank as the axis of symmetry, which facilitates alternating use and easy replacement.

[0013] Preferably, the end of the locking block away from the second spring is set as an inclined surface, the side of the fixed block away from the moving block is set as an inclined surface, and the moving block is set as a right-angled trapezoidal block. The locking block and the fixed block abutting against each other away from the inclined surface can limit each other, and the moving block cooperating with the fixed block can easily release the limit.

[0014] Compared with the prior art, this utility model provides a water-circulating metal engraving machine, which has the following beneficial effects:

[0015] 1. This water-circulating metal engraving machine, through its adjustable components, allows for filter plate replacement by pulling the lever. The fixed block limits the locking block, causing the insertion rod to disengage from the insertion hole. At this point, rotating the rocker arm shifts the water guide channel, changing the water flow direction and allowing the filter plate to work through another set of filter plates. The filter plate to be replaced can then be pulled out and replaced without stopping the machine, thus improving processing efficiency.

[0016] 2. This water-circulating metal engraving machine, through its cooling components, activates the water pump, and cool water is sprayed from the nozzle through a three-way valve and conduit for cooling. The cooled wastewater then re-enters the water tank through a leak, funnel, and inlet pipe, is filtered by a filter plate, and is then pumped out again for cooling, thus achieving water circulation and avoiding water waste.

[0026] like Figures 1-8 As shown, this utility model provides a technical solution: a water-circulating metal engraving machine, including an operating table 1, with a drain hole 6 at the bottom of the operating table 1, a power spindle 2 installed on the top of the operating table 1, a milling cutter 3 installed at the bottom of the power spindle 2, and a cooling assembly 7 for circulating wastewater on the surface of the operating table 1. The cooling assembly 7 includes a water tank 70, a partition 74, a base plate 75, and a filter plate 76. The surface of the water tank 70 is provided with an adjustment assembly 8 that allows the filter plate 76 to be replaced without stopping the equipment. The adjustment assembly 8 includes: a fixed base 80, a water guide channel 81, a rocker arm 82, an insertion hole 83, a fixed frame 84, a sliding plate 85, an insertion rod 86, a pull rod 87, a through hole 88, a first spring 800, a limiting component 89, a sliding groove 890, a locking block 891, a second spring 892, a fixing block 893, a moving block 894, and a magnet 895.

[0027] A fixed base 80 is fixed to the top of the inner wall of the water tank 70. A water guide groove 81 is hinged to the inner side of the fixed base 80. A rocker arm 82 is rotatably connected to the surface of the water tank 70. The output shaft of the rocker arm 82 passes through the water tank 70 and the fixed base 80, and the output shaft of the rocker arm 82 is fixed to the surface of the water guide groove 81. The adjustment assembly 8 also includes a socket 83, which is opened on the surface of the rocker arm 82. A fixed frame 84 is fixed to the top of the water tank 70. A sliding plate 85 is slidably connected to the inner wall of the fixed frame 84. The surface of the sliding plate 85 is fixed. The slide plate 85 has a rod 86, a pull rod 87 is fixed to the top of the slide plate 85, a through hole 88 is opened on the top of the fixed frame 84, the pull rod 87 is fixed to the top of the slide plate 85, the top of the pull rod 87 passes through the through hole 88, a spring 800 is fixed to the surface of the slide plate 85, and the end of the spring 800 away from the slide plate 85 is fixed to the inner wall of the fixed frame 84. The adjustment component 8 also includes a limiting member 89. By rotating the rocker arm 82, the water guide channel 81 can be shifted, thereby changing the direction of water flow, which facilitates the subsequent replacement of the filter plate 76.

[0028] The limiting component 89 includes a slide groove 890, which is formed on the surface of the slide plate 85. A locking block 891 is slidably connected to the inner wall of the slide groove 890. A second spring 892 is fixed to the surface of the locking block 891. The end of the second spring 892 away from the locking block 891 is fixed to the inner wall of the slide groove 890. A fixing block 893 is fixed inside the fixing frame 84. A moving block 894 is slidably connected to the inner wall of the fixing frame 84. A magnet 895 is fixed to the inner wall of the fixing frame 84. The magnet 895 is magnetically connected to the moving block 894. The end of the locking block 891 away from the second spring 892 is set as an inclined surface. The side of the fixing block 893 away from the moving block 894 is set as an inclined surface. The moving block 894 is set as a right-angled trapezoidal block. When the slide plate 85 moves, it drives the locking block 891. 1. Movement: When the side of the locking block 891 away from the inclined plane abuts against the side of the fixed block 893 away from the inclined plane, the locking block 891 and the sliding plate 85 are limited. When the rocker arm 82 rotates to the appropriate angle, the pull rod 87 is pulled again. When the locking block 891 is located on the side of the moving block 894 away from the fixed block 893, the pull rod 87 is released, the spring 800 is released, and the sliding plate 85 drives the locking block 891 and the moving block 894 to move towards the fixed block 893 in sync. When the surface of the moving block 894 is in contact with the surface of the fixed block 893, the locking block 891 moves along the surface of the moving block 894 and the fixed block 893, and the limitation is released. The insertion rod 86 is inserted into the insertion hole 83, which limits the rocker arm 82 and avoids the impact of water flow, which would cause the water guide channel 81 to reverse.

[0029] A water tank 70 is fixed to the bottom of the operating table 1. A partition 74 is fixed to the bottom of the inner wall of the water tank 70. A water inlet 71 is opened on the surface of the water tank 70. A water inlet pipe 72 is opened on the top of the water tank 70. A funnel 73 is connected to the top of the water inlet pipe 72. The top of the funnel 73 is fixed to the bottom of the operating table 1. A base plate 75 is fixed to the surface of the partition 74. A filter plate 76 is placed on the top of the base plate 75. The end of the filter plate 76 away from the water tank 70 passes through the water tank 70. A tee 77 is installed on the back of the water tank 70. A water pump 78 is connected to the end of the tee 77 away from the water tank 70. The suction end of the water pump 78 is fixed to the end of the tee 77 away from the water tank 70. A conduit 79 is fixed to the suction end of the water pump 78. The conduit 79 is far from the water tank 70. One end of the water pump 78 passes through the operating table 1. A nozzle 700 is fixed to the end of the conduit 79 furthest from the water pump 78. Two sets of base plates 75 and filter plates 76 are provided, symmetrically arranged about the center line of the water tank 70. Cooling water is injected through the inlet 71. Turning on the water pump 78 allows the cooling water to be sprayed from the nozzle 700 through the tee 77 and conduit 79 for cooling. The cooled wastewater re-enters the water tank 70 through the drain hole 6, funnel 73, and inlet pipe 72. The water then flows into the guide trough 81 for guidance, is filtered by a set of filter plates 76, and is pumped out again by the water pump 78 for cooling, thus achieving water circulation and preventing water waste. An electric push rod 4 is fixed to the inner wall of the operating table 1. A clamping plate 5 is fixed to the output end of the electric push rod 4 for clamping the workpiece.

[0030] When engraving is required, place the workpiece at the bottom of the operating table 1, turn on the electric push rod 4 to clamp the workpiece with the clamping plate 5, and then inject cooling water through the water inlet 71. At the same time, pull the pull rod 87, and the slide plate 85 will cause the insertion rod 86 to disengage from the insertion hole 83. Then, the rocker arm 82 can be rotated normally. At this time, the rocker arm 82 will cause the water guide channel 81 to shift, and the outlet of the water guide channel 81 will face a set of filter plates 76. At the same time, when the slide plate 85 moves, the inclined surface of the locking block 891 will abut against the surface of the fixed block 893, so that the locking block 891 can enter the slide groove 890. The spring 1 800 and the spring 2 892 will be compressed. When the locking block 891 is located between the moving block 894 and the fixed block When the position is between 893 and 894, release the lever 87. Spring 892 will cause the locking block 891 to reset, so that the side of the locking block 891 away from the inclined plane abuts against the side of the fixed block 893 away from the inclined plane. This limits the locking block 891 and the sliding plate 85. When the rocker arm 82 rotates to the appropriate angle, pull the lever 87 again. At this time, the surface of the locking block 891 will contact the surface of the moving block 894. When the locking block 891 is on the side of the moving block 894 away from the fixed block 893, release the lever 87. Spring 800 will release, which will cause the sliding plate 85 to reset. At this time, the locking block 891 will cause the moving block 894 to move synchronously closer to the fixed block 893. When the moving block 894... When surface 94 is in contact with surface 893, locking block 891 moves along surfaces 894 and 893, releasing the limit. Magnet 895 attracts moving block 894 to reset. At this time, insert rod 86 is inserted into insertion hole 83, limiting rocker arm 82 and preventing water flow impact from causing water guide channel 81 to reverse. Water pump 78 is then turned on, allowing cooling water to spray from nozzle 700 through T-junction 77 and pipe 79. Power spindle 2 and milling cutter 3 can then be turned on to engrave the workpiece while cooling water cools it. Waste water after cooling returns to water tank 70 through drain hole 6, funnel 73, and inlet pipe 72. At this time, the water flows into the water guide channel 81 for guidance, is filtered through a set of filter plates 76, and is then pumped out again by the water pump 78 for cooling, which realizes water circulation and avoids water waste. When a set of filter plates 76 needs to be replaced after long-term use, repeat the above steps and reverse the rocker arm 82 to change the direction of water flow in the water guide channel 81, so that the sewage passes through another set of filter plates 76. At this time, the filter plate 76 that needs to be replaced can be pulled out for cleaning and replacement without stopping the equipment, which improves processing efficiency. During installation, insert the filter plate 76 into the water tank 70 so that the filter plate 76 is located on the top of the base plate 75 for stability.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
