Description

Technical Field

[0001] This utility model relates to the field of cutting machinery technology, and in particular to a tabletop CNC cutting machine. Background Technology

[0002] Cutting machinery refers to mechanical equipment used for cutting various materials, widely used in industrial production and manufacturing processes. A tabletop CNC cutting machine is a type of cutting machinery; it uses a digital program to drive the machine tool's movement, and the accompanying cutting tools cut objects. It belongs to the category of mechatronics cutting equipment.

[0003] However, conventional cutting machines generate a large amount of dust during the cutting process, which escapes into the air and pollutes the surrounding environment. Furthermore, the saw blade generates high temperatures when rotating at high speeds, and conventional cutting machines are ineffective at cooling the blade. Therefore, how to effectively collect dust while simultaneously cooling the circular saw blade is a crucial issue that needs to be addressed in the design of benchtop CNC cutting machines. Utility Model Content

[0004] This invention provides a desktop CNC cutting machine to address the problems of dust pollution caused by cutting and the inability to effectively dissipate heat from the saw blade.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a tabletop CNC cutting machine, including a worktable, and further comprising: ball bearing sliders fixedly connected at equal distances to both ends of the bottom sidewall of the worktable, the ball bearing sliders being slidably connected to a ball bearing guide rail, and the ball bearing guide rail being fixedly connected to the top sidewall of a support frame.

[0007] A clamping and fixing structure is provided on the worktable;

[0008] A heat dissipation and collection structure is installed below the workbench to collect dust.

[0009] A cooling structure is provided within a heat dissipation collection structure.

[0010] Preferably, a second support frame is fixedly connected to the top side wall of the first support frame, an asynchronous motor is fixedly connected to the second support frame, a rotating wheel is fixedly connected to the rotating end of the asynchronous motor, a rotating shaft is rotatably connected to the side wall of the second support frame, one end of the rotating shaft is fixedly connected to the first rotating wheel, a transmission belt is sleeved between the first rotating wheel and the second rotating wheel, and a circular saw blade is fixedly connected to the other end of the rotating shaft.

[0011] In this technical solution, an asynchronous motor drives the second rotating wheel to rotate, the second rotating wheel drives the first rotating wheel to rotate via a transmission belt, and the first rotating wheel drives the circular saw blade to rotate via a rotating shaft. The circular saw blade cuts and processes the moving workpiece.

[0012] Preferably, a servo motor is fixedly connected to the top side wall of the support frame, a lead screw is fixedly connected to the rotating end of the servo motor, a moving block is threaded onto the lead screw, and the moving block is fixedly connected to the bottom side wall of the worktable.

[0013] In this technical solution, a servo motor drives a lead screw to rotate, the lead screw rotation drives a moving block to move, the moving block drives a worktable to move, and the worktable drives a ball block slider to slide on a ball guide rail.

[0014] Preferably, the clamping and fixing structure includes a clamping plate, a movable frame, and an electric push rod. The electric push rod is fixedly connected to the side walls on both sides of the movable block, and the other end of the electric push rod is fixedly connected to the movable frame. The movable frame is slidably connected to the worktable, and a clamping plate is fixedly connected between the movable frames. The bottom side wall of the clamping plate is attached to the top side wall of the worktable.

[0015] In this technical solution, the electric push rod shortens to move the moving frame, and the moving frame moves the clamping plate, so that the clamping plate tightly clamps and fixes the workpiece. The electric push rods on both sides of the moving block can be independently extended and retracted.

[0016] Preferably, the heat dissipation and collection structure includes a fixed housing, a suction pipe, a blower pipe, a first partition plate, a ventilation tube, an exhaust fan, and a dust filter. The fixed housing is fixedly connected to the side wall of the first support frame. The suction pipe is fixedly connected at equal intervals to the side wall of the ball bearing guide rail. One end of the suction pipe is fixedly connected to the side wall of one side of the fixed housing. The blower pipe is fixedly connected to the side wall of the second support frame. One end of the blower pipe is fixedly connected to the side wall of the other side of the fixed housing. The other ends of the blower pipe and the suction pipe extend above the workbench. Two first partition plates are fixedly connected inside the fixed housing. A ventilation tube is fixedly connected to the two first partition plates. An exhaust fan and two dust filters are fixedly connected inside the ventilation tube.

[0017] In this technical solution, the exhaust fan draws air, causing the dust suction pipe to suck up the dust generated during cutting and processing, which is then adsorbed and fixed inside the housing and collected in the collection box. The extracted air is then blown out through the blower pipe on the other side towards the asynchronous motor of the circular saw blade.

[0018] Preferably, the exhaust fan is located between two dust filters.

[0019] In this technical solution, the dustproof netting at the top intercepts dust, preventing it from entering the exhaust fan.

[0020] Preferably, a collection box is slidably connected to the bottom side wall of the fixed housing, and a handle is fixedly connected to the side wall of the collection box.

[0021] In this technical solution, the collection box can be easily pulled out using a handle for dust removal.

[0022] Preferably, the cooling structure includes a second partition plate, a water pump, a thermoelectric cooler, a heat-conducting plate, a water pipe, an inlet pipe, and an outlet pipe. The second partition plate is fixedly connected between the first partition plate and the side wall of the fixed housing. The water pipe and the inlet pipe are fixedly connected at equal intervals to the side wall of the second partition plate. The top of the water pipe and the inlet pipe are respectively fixedly connected to the two ends of the water pipe. The bottom end of the inlet pipe is fixedly connected to the water pump.

The thermoelectric cooler is fixedly connected at equal intervals to the bottom side wall of the heat-conducting plate. The thermoelectric cooler extends downwards out of the fixed housing.

[0023] In this technical solution, the heat-conducting plate is made of a material with good thermal conductivity, and the semiconductor cooler is used for cooling. The clean water inside the fixed shell exchanges heat with the semiconductor cooler through the heat-conducting plate, which lowers the temperature of the clean water. The water pump draws the cooler clean water, which circulates through the inlet pipe, the outlet pipe and the outlet pipe and then returns to the clean water below. When the flowing air passes between the outlet pipes, it exchanges heat with the outlet pipes, which lowers the temperature of the flowing air.

[0024] Preferably, the cavity below the second partition plate is filled with clean water.

[0025] Preferably, the water pipe is arranged in a spiral shape.

[0026] In this technical solution, the water pipe is made of a material with good thermal conductivity. The spiral-shaped water pipe increases the path of the water flow, so that the cool water can fully exchange heat with the flowing air.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. The exhaust fan draws in air, causing the suction pipe to suck up the dust generated during cutting and processing, which is then drawn into the housing and collected in the collection box. The dustproof net on top intercepts the dust, preventing it from entering the exhaust fan. The extracted air is then discharged through the blower on the other side, facilitating the collection of dust generated during the cutting process and preventing dust pollution of the surrounding environment.

[0030] 2. Cooling is achieved through a semiconductor cooler. The clean water inside the fixed housing exchanges heat with the semiconductor cooler through a heat-conducting plate, causing the water temperature to drop. The water pump draws in the cooler water, which circulates through the inlet pipe, the outlet pipe, and the outlet pipe before returning to the clean water below. When the flowing air passes between the outlet pipes, it exchanges heat with the outlet pipes, causing the air temperature to drop. The cooled air is then blown out onto the circular saw blade through the blower pipe, which can dissipate heat and cool the circular saw blade. This facilitates better heat dissipation and cooling of the circular saw blade while collecting dust. Attached Figure Description
