Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a CNC horizontal machining center with an inverted T-shaped structure. Background Technology

[0002] CNC horizontal machining centers are high-precision, high-efficiency CNC machine tools widely used in aerospace, automotive manufacturing, mold processing, and other fields. Their core feature is the ability to perform multi-faceted machining of workpieces through the cooperation of a horizontal spindle and a horizontal worktable, making them particularly suitable for machining large and heavy workpieces.

[0003] Chinese Patent CN205414935U discloses a fixed-column horizontal machining center, including: a base, a column, a spindle box, a saddle, a rotary table, X-axis guide rails, Y-axis guide rails, and Z-axis guide rails. This invention modifies the base into an inverted T-shape, with the column fixed on the base. A Y-axis guide rail is mounted on the column, and the spindle box moves up and down along the Y-axis guide rail. The X-axis guide rail is mounted on the base, and the saddle moves along the X-axis guide rail above the base. The Z-axis guide rail is located on the saddle, and the rotary table moves along the Z-axis guide rail above the saddle. When machining a workpiece, the spindle holds the tool, and with the movement along the X, Y, and Z axes, as well as the rotation of the rotary table, machining can be performed on the side of the workpiece in all directions. However, this device has the following drawbacks: it cannot dissipate heat from the tool and workpiece during machining, causing heat to gradually accumulate during long-term continuous machining, potentially leading to an overall increase in workpiece temperature, affecting dimensional stability and machining quality. Utility Model Content

[0004] The purpose of this invention is to provide a CNC horizontal machining center with an inverted T-shaped structure, which can dissipate heat and cool down the cutting tools and workpieces during machining operations, thereby improving machining quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a CNC horizontal machining center with an inverted T-shaped structure, including a frame, a machining table disposed on the frame, and a turntable rotatably disposed on the machining table. A mounting frame is disposed on one side of the machining table, a fan is disposed on the mounting frame, an air outlet of the fan is connected to an air guide pipe, an exhaust port is disposed on the air guide pipe, and a nozzle is fixed at the exhaust port.

[0006] By adopting the above technical solution, when the cutting tool is machining the workpiece located on the turntable, the fan is started, and air is sent to the cutting tool and the workpiece through the air duct, exhaust port and nozzle to achieve heat dissipation and cooling, improve machining stability, reduce the wear and deformation of the cutting tool caused by high temperature, extend the service life of the cutting tool, reduce the thermal deformation of the workpiece caused by high temperature, and ensure the machining accuracy of the workpiece.

[0007] A further feature of this invention is that multiple exhaust vents are provided along the axial direction of the air guide pipe, and multiple corresponding air nozzles are provided.

[0008] By adopting the above technical solutions, the overall cooling efficiency can be improved.

[0009] A further feature of this invention is that the processing table is fixed with a fixed frame, the mounting frame is disposed on the fixed frame, and the fixed frame is provided with a lifting device for driving the mounting frame to rise and fall.

[0010] By adopting the above technical solution, the height of the mounting frame and the fan can be adjusted by the lifting device, so that it can be adapted to workpieces of different sizes on the processing table. At the same time, it can cool the workpieces at different heights. When the turntable rotates for processing, it can also achieve comprehensive cooling of the workpieces, thus improving the flexibility and adaptability of the overall device.

[0011] A further feature of this invention is that the lifting device is a lifting cylinder fixed to the fixed frame, and the output end of the lifting cylinder is fixed to the mounting frame.

[0012] By adopting the above technical solution, the mounting bracket can be raised and lowered directly by a lifting cylinder, which is more efficient.

[0013] A further feature of this invention is that the fixing frame is threadedly connected to both sides with fixing bolts that extend into the processing table.

[0014] By adopting the above technical solution, the fixing frame is installed on the processing table by fixing bolts. The position of the fixing frame and the fan can be quickly disassembled, adjusted or maintained as needed, making the overall structure more flexible.

[0015] A further feature of this invention is that an air guide box is fixed on the mounting frame, the air outlet of the fan is connected to the air guide box, and the end of the air guide pipe is rotatably connected to the air guide box and driven to swing by a heat dissipation component mounted on the mounting frame.

[0016] By adopting the above technical solution, the heat dissipation component drives the air duct to rotate and swing back and forth to achieve all-round heat dissipation of the tool and workpiece, thereby improving heat dissipation efficiency and processing stability.

[0017] A further feature of this invention is that the heat dissipation assembly includes a drive shaft rotatably connected to the mounting bracket, a drive device for driving the drive shaft to rotate, a turntable eccentrically fixed to the drive shaft, and a crankshaft fixed outside the turntable. The end of the air duct is fixed with a rotating shaft rotatably connected to the mounting bracket. A rotating plate is fixed to the end of the rotating shaft away from the air duct. A fixing rod is fixed to the end of the rotating plate away from the rotating shaft. The end of the crankshaft away from the turntable is sleeved and slidably attached to the fixing rod.

[0018] By adopting the above technical solution, the drive device drives the drive shaft and turntable to rotate, which in turn drives the crankshaft to move back and forth and rise and fall. In turn, the end of the crankshaft drives the fixed rod, the turntable and the shaft to rotate back and forth, so as to realize the back and forth swing of the nozzle for heat dissipation.

[0019] A further feature of this invention is that the driving device is a drive motor mounted on the mounting bracket.

[0020] By adopting the above technical solution, the drive motor drives the drive shaft to rotate, thereby improving heat dissipation efficiency.

[0021] The beneficial effects of this utility model are:

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example 1: A CNC horizontal machining center with an inverted T-shaped structure, such as... Figure 1 As shown, it includes a frame 1, a processing table 2 set on the frame 1, and a turntable 3 rotatably set on the processing table 2. A mounting frame 4 is set on one side of the processing table 2, and a fan 5 is set on the mounting frame 4. The air outlet of the fan 5 is connected to an air guide pipe 6. An exhaust port is provided on the air guide pipe 6, and a nozzle 7 is fixed at the exhaust port. When processing, the fan 5 is started, and air is sent to the workpiece and tool through the air guide pipe 6, the exhaust port and the nozzle 7.

[0031] Furthermore, multiple exhaust vents are provided along the axial direction of the air duct 6, and multiple corresponding air nozzles 7 are provided to improve air supply efficiency.

[0032] like Figure 1 As shown, the processing table 2 is fixed with a fixed frame 8, and the mounting frame 4 is set on the fixed frame 8. The fixed frame 8 is equipped with a lifting device that drives the mounting frame 4 to rise and fall. The lifting device is a lifting cylinder 9 fixed to the fixed frame 8. The output end of the lifting cylinder 9 is fixed to the mounting frame 4. When the lifting cylinder 9 is started, it drives the mounting frame 4 to rise and fall, adjusting the height of the mounting frame 4 and the fan 5 so that it can adapt to workpieces of different sizes on the processing table 2, and at the same time, it can cool the workpieces at different heights.

[0033] like Figure 1 As shown, the fixing bracket 8 has threaded connections on both sides with fixing bolts 10 that extend into the processing table 2, allowing the fixing bracket 8 to be quickly assembled and disassembled via the fixing bolts 10.

[0034] like Figure 1 As shown, an air guide box 11 is fixed on the mounting frame 4. The air outlet of the fan 5 is connected to the air guide box 11. The end of the air guide pipe 6 is rotatably connected to the air guide box 11 and is driven to swing by the heat dissipation component 12 installed on the mounting frame 4. The fan 5 delivers air through the air guide box 11, the air guide pipe 6 and the nozzle 7. The heat dissipation component 12 drives the air guide pipe 6 to reciprocate and swing to achieve all-round heat dissipation for the tool and the workpiece.

[0035] like Figure 2 As shown, the heat dissipation assembly 12 includes a drive shaft 121 rotatably connected to the mounting bracket 4, a drive device for driving the drive shaft 121 to rotate, a turntable 123 eccentrically fixed to the drive shaft 121, and a crankshaft 124 fixed outside the turntable 123. The end of the air duct 6 is fixed with a rotating shaft 125 rotatably connected to the mounting bracket 4. A rotating plate 126 is fixed to the end of the rotating shaft 125 away from the air duct 6. A fixing rod 127 is fixed to the end of the rotating plate 126 away from the rotating shaft 125. The end of the crankshaft 124 away from the turntable 123 is sleeved and slidably connected to the fixing rod 127. The drive device is a drive motor 122 mounted on the mounting bracket 4.

[0036] Working principle: When the cutting tool processes the workpiece located on the turntable 3, the fan 5 is started, and air is sent to the cutting tool and workpiece through the air box 11, air duct 6, exhaust port and nozzle 7 to achieve heat dissipation and cooling. At the same time, the drive motor 122 is started, and the drive motor 122 drives the drive shaft 121 to rotate. The drive shaft 121 and the turntable 123 rotate synchronously, which in turn drives the crankshaft 124 to move back and forth and lift up and down. Then, the end of the crankshaft 124 drives the fixed rod 127, the rotating plate 126 and the rotating shaft 125 to rotate back and forth, so that the nozzle 7 swings back and forth to dissipate heat, achieving all-round heat dissipation for the cutting tool and workpiece and improving heat dissipation efficiency.
