[0005] The above devices all have the following shortcomings: during high-speed cutting, a large amount of heat is generated, which causes thermal deformation of the workpiece, tool or machine tool, thereby affecting the machining accuracy. Utility Model Content

[0006] The purpose of this invention is to provide a CNC gantry machining center with high-speed chip cutting capability, which can provide coolant to reduce cutting temperature during the cutting process.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a CNC gantry machining center with high-speed chip cutting, comprising a machine tool, a gantry frame disposed on the machine tool, a slide mounted on the gantry frame, and a cutting machine mounted on the slide. The slide is fixed with a liquid outlet nozzle whose end is close to the cutting machine. A machining table is slidably disposed on the machine tool. A clamping plate is slidably disposed on one side of the machining table, and a collection groove is fixed on the other side. The machining table is provided with a plurality of inwardly recessed guide grooves.

[0008] By adopting the above technical solution, the clamping plate is used to clamp the workpiece on the machining table. When the cutting machine is started to cut the workpiece on the machining table, the liquid spray nozzle sprays coolant onto the workpiece and the cutting machine head to reduce the cutting temperature and avoid thermal deformation of the workpiece and tool caused by a large amount of heat. At the same time, it washes away the chips in the cutting area to prevent chip accumulation from affecting the machining quality and tool performance and improve machining accuracy. Afterwards, the coolant flows into the collection tank through the guide groove on the machining table to realize recycling and reuse, saving resources and reducing costs.

[0009] A further feature of this invention is that: a box is fixed to the side beam of the gantry frame, a pump body is installed inside the box, the water inlet pipe of the pump body is connected to the inside of the box, a liquid outlet pipe is connected to the upper end of the liquid outlet nozzle, and the end of the liquid outlet pipe away from the liquid outlet nozzle extends into the box and is connected to the water outlet pipe of the pump body.

[0010] By adopting the above technical solution, coolant is stored in the tank, and the coolant is drawn out of the tank by the pump and delivered to the outlet nozzle through the outlet pipe to spray coolant onto the workpiece and the cutting machine tool head, thereby reducing the cutting temperature.

[0011] A further feature of this invention is that: a drive groove is fixed on one side of the processing table, a drive screw with opposite threads at both ends is rotatably connected in the drive groove, a movable block that slides in the drive groove is threaded to both ends of the drive screw, the movable block is fixedly connected to the clamping plate, and a drive motor that drives the drive screw to rotate is installed outside the drive groove.

[0012] By adopting the above technical solution, the drive motor is started to drive the drive screw to rotate, so that the moving blocks on both sides and the clamping plate move relative to each other to clamp the workpiece on the processing table, avoiding the workpiece moving during cutting work and affecting the processing accuracy, thus improving processing efficiency.

[0013] A further feature of this invention is that the bottom of the clamping plate is in contact with the upper surface of the processing table.

[0014] By adopting the above technical solution, while the clamping plates move relative to each other, the coolant remaining on the processing table can be scraped into the guide groove, thus avoiding the accumulation of coolant on the processing table and affecting subsequent processing, while improving the coolant recovery efficiency.

[0015] A further feature of this invention is that the lower end of the guide channel is inclined towards the collection channel, and the upper end of the collection channel is lower than the lower end of the guide channel.

[0016] By adopting the above technical solution, the coolant flowing into the guide channel can flow smoothly into the collection tank, thereby improving the coolant recovery efficiency.

[0017] A further feature of this invention is that a filter plate is fixed inside the collection tank.

[0018] By adopting the above technical solution, the coolant flows through the filter plate into the collection tank, and the filter plate screens out the waste debris in the coolant. After cleaning the waste debris on the filter plate, the coolant in the collection tank can be poured into the tank for reuse.

[0019] A further feature of this invention is that the collection tank and the processing table are detachably connected.

[0020] By adopting the above technical solution, the coolant in the collection tank can be poured into the tank for reuse by removing the collection tank from the processing table.

[0021] A further feature of this invention is that mounting plates are fixed on both sides of the collection trough, and the mounting plates are threadedly connected with mounting bolts that extend into the processing table.

[0022] By adopting the above technical solution, the collection tank can be quickly installed on the processing table or quickly removed from the processing table by using mounting bolts and mounting plates.

[0023] A further feature of this invention is that an adjusting screw is rotatably connected to the machine tool, the bottom of the processing table is threadedly connected to the adjusting screw, and the adjusting screw is driven to rotate by an adjusting motor installed on the machine tool.

[0024] By adopting the above technical solution, the adjusting motor drives the adjusting screw to rotate, which in turn moves the machining table to adjust the relative positions of the machining table, the workpiece and the cutting machine. A guide rod is fixed on the machine tool that passes through the machining table to limit and guide the adjustment of the machining table.

[0025] A further feature of this invention is that an adjusting screw two is rotatably connected to the gantry frame, the slide block is threadedly connected to the adjusting screw two and slidably connected to the gantry frame, and the adjusting screw two is driven to rotate by an adjusting motor two installed on the gantry frame.

[0026] By adopting the above technical solution, the second motor drives the second adjusting screw to rotate, thereby adjusting the second adjusting screw to move the slide to adjust the relative position of the processing table, workpiece and cutting machine. The gantry is equipped with a slide rail for the slide to slide, thereby limiting and guiding the adjustment of the slide.

[0027] The beneficial effects of this utility model are:

[0028] 1. The clamping plate is used to clamp the workpiece on the machining table. When the cutting machine is started to cut the workpiece on the machining table, the liquid spray nozzle sprays coolant onto the workpiece and the cutting machine head to reduce the cutting temperature and avoid thermal deformation of the workpiece and tool caused by a large amount of heat. At the same time, it washes away the chips in the cutting area to prevent chip accumulation from affecting the machining quality and tool performance and improve machining accuracy.

[0029] 2. The coolant can flow into the collection tank through the guide channel on the machining table, realizing recycling and reuse, saving resources and reducing costs;

[0030] 3. While the clamping plates move relative to each other, they can scrape the coolant remaining on the processing table into the guide groove, thus avoiding the accumulation of coolant on the processing table and affecting subsequent processing, while improving the coolant recovery efficiency.

[0031] 4. The coolant flows through the filter plate into the collection tank, where the filter plate screens out the waste particles in the coolant. After cleaning the waste particles from the filter plate, the coolant in the collection tank can be poured back into the tank for reuse. Attached Figure Description

Figure 1-2As shown, it includes a machine tool 1, a gantry 2 mounted on the machine tool 1, a slide 3 mounted on the gantry 2, and a cutting machine 4 mounted on the slide 3.

The upper end of the liquid outlet nozzle 5 is connected to a liquid outlet pipe 11. The end of the liquid outlet pipe 11 away from the liquid outlet nozzle 5 extends into the box 10 and is connected to the pump body's water outlet pipe.

[0040] like Figure 1 As shown, a drive groove 12 is fixed on one side of the processing table 6. A drive screw 13 with opposite threads at both ends is rotatably connected inside the drive groove 12.

[0041] Furthermore, the bottom of the clamping plate 7 is in contact with the upper surface of the processing table 6.

[0042] like Figure 3 As shown, the lower end of the guide channel 9 is inclined to the collection channel 8, and the upper end of the collection channel 8 is lower than the lower end of the guide channel 9.

[0043] Furthermore, a filter plate 16 is fixed inside the collection tank 8.
