Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] Example 1

[0051] like Figure 1 As shown, a CNC machine tool comprises: a workbench 2, a machine tool box 1, a machining tool, a clamping assembly, and a leakage slit 201;

[0052] A machine tool box 1 is arranged above the workbench 2, the front of the machine tool box 1 is an open structure, and a machine tool box protection door (not shown in the figure) is movably arranged on the open structure; the left and right side panels and the back side panel of the machine tool box 1 are respectively arranged at the edges corresponding to the workbench 2;

[0053] A clamping assembly is provided on the upper surface of the workbench 2 for clamping and fixing the material of the part to be processed; Figure 3 As shown, the clamping assembly includes: a clamping seat 5, a clamping block 6 and a screw 504;

[0054] The clamping seat 5 is centrally arranged on the upper surface of the workbench 2; two clamping seats 5 are symmetrically arranged front and back;

[0055] A clamping block 6 is disposed on each of the opposite surfaces of the two clamping seats 5, and the clamping block 6 has no contact with the clamping seat 5, that is, the clamping block 6 and the clamping seat 5 are independent, and there is no connection structure relationship between the two.

[0056] A screw rod 504 passes through the clamping seat 5, and the contact surface between the screw rod 504 and the clamping seat 5 is arranged to be threaded, and the screw rod 504 is screwed, so that the screw rod 504 can move forward and backward relative to the clamping seat 5;

[0057] One end of the screw rod 504 is rotatably connected to the non-clamping surface of the clamping block 6 through a rotating shaft, and the other end is located outside the clamping seat 5. By simultaneously rotating the two screw rods 504, the two clamping blocks 6 can move toward each other to gradually clamp the part material to be processed between the clamping blocks 6; or the two clamping blocks 6 can move away from each other to loosen the part material to be processed.

[0058] A machining tool is provided below the top plate 7 of the machine tool box 1 for cutting or grinding the material of the part to be machined;

[0059] like Figure 6 A tool control box 8 is centrally arranged below the top plate 7 of the box body; a telescopic column 9 is arranged in the middle of the lower bottom surface of the tool control box 8; a tool 10 is arranged on the telescopic end surface of the telescopic column 9; the telescopic column 9 enables the tool 10 to be lowered to a suitable height with the material of the part to be processed on the clamping assembly, so that it can process the material; a tool control electromechanical component is arranged in the tool control box 8, which is used to drive the extension or contraction of the telescopic column 9 and drive the operation of the tool; the telescopic column 9 and the electromechanical component of the telescopic column are existing equipment on the existing machine tools; the driving principle, circuit and electromechanical component of the tool 10 are also existing equipment on the existing machine tools; for those skilled in the art, it is an existing technology that can be directly adopted and will not be repeated here.

[0060] like Figure 6 As shown, a universal tube 11 is arranged on the lower bottom surface of the tool control box 8 on the left and right sides of the telescopic column 9; the universal tube 11 is connected to the coolant storage box in the tool control box 8; a valve is arranged on the universal tube 11; the nozzle end of the universal tube 11 is close to the tool, and when the tool processes the part material, the nozzle of the universal tube 11 can spray coolant on the tool and the part material. The tool cuts and grinds the part material at high speed, and the temperature will rise sharply. The coolant can cool the surface of the tool and the part material; at the same time, the debris on the surface of the tool and the part material can also be flushed.

[0061] like Figure 4 As shown, a plurality of leakage slits 201 are provided on the upper surface of the workbench 2, and the interior of the workbench 2 is provided as a hollow collection space; a drainage pipe 203 is provided on one side of the workbench 2, and the drainage pipe 203 is communicated with the collection space; in this way, the coolant flushes the debris, and can carry the debris together and leak from the leakage slits 201 to the collection space below the workbench 2, and then be discharged from the collection space through the drainage pipe 203. In this way, the mixture of debris and coolant can be prevented from being accumulated on the surface of the workbench 2. When a batch of parts is processed or the production of the day is completed, the mixture of debris and coolant accumulates too much and is difficult to clean; or the mixture of debris and coolant accumulates and adheres to the mechanical parts, which may affect the normal operation of the mechanical parts, and eventually may affect the processing of the part material.

[0062] Example 2

[0063] Based on Example 1, in Example 1, a seepage slit 201 is provided on the upper surface of the workbench 2, and a hollow collecting space is provided inside the workbench 2; the mixture of debris and coolant flowing from the seepage slit 201 into the collecting space needs to be discharged from the discharge pipe 203 on one side under the condition of natural flow; however, such a discharge method has a too slow rate and may not be completely discharged;

[0064] In this embodiment, the bottom of the collection space in the workbench 2 is set to a sloped structure with the left side higher and the right side lower; the debris discharge pipe 203 is set on the right side of the workbench 2 and communicates with the right side of the collection space; in this way, by utilizing a height difference, the debris and coolant mixture flowing into the collection space can be discharged from the debris discharge pipe 203 faster under the high and low slope structure, and can be completely discharged from the collection space to avoid residue.

[0065] Example 3

[0066] Based on Example 2, as a preferred implementation, Figure 5 As shown, in this embodiment, based on the bottom structure of the collecting space which is higher on the left and lower on the right in Embodiment 2, a center line (virtual) is set in the middle position of the sloped structure from left to right, and the sloped structure is concave at the center line, so that the cross section of the sloped structure presents a "V"-shaped structure.

[0067] In this way, the mixture of chips and coolant is collected in the concave part and then discharged along the slope structure, which further accelerates the discharge rate and discharge effect of the mixture of chips and coolant.

[0068] Example 4

[0069] Based on Example 1, in Example 1, the clamping assembly for clamping the material of the part to be processed is fixedly connected to the upper surface of the workbench 2; that is, the clamping assembly cannot move on the upper surface of the workbench 2 to adjust the position of the material of the part to be processed; and the position of the clamping assembly may not be the best position for cutting and grinding at certain angles of the material, and the position of the clamping assembly needs to be fine-tuned;

[0070] like Figure 2 As shown, a workbench slide rail 3 is provided on the upper surface of the workbench 2 near the front and rear sides; a sliding frame 4 is movably provided on the workbench slide rail 3; the sliding frame 4 can move along the X-axis on the workbench 2. A clamping assembly is movably provided on the sliding frame 4, so that the clamping assembly can move along the Y-axis on the sliding frame 4.

[0071] The movable connection relationship between the clamping assembly and the sliding frame 4 is set as follows:

[0072] A slide groove 401 is provided on the slide frame 4; a slide block 501 is provided below the clamping seat 5 on the clamping assembly;

[0073] The slide block 501 is movably embedded in the slide groove 401, so that the clamping seat 5 together with the clamping block 6 can move forward and backward along the Y axis relative to the sliding frame 4.

[0074] The position of the clamping assembly in the X-axis direction can be adjusted by moving the sliding frame 4, and the position of the clamping assembly in the Y-axis direction can be adjusted by moving the clamping assembly on the sliding frame 4; thus, accurate positioning of the clamping assembly can be achieved.

[0075] Example 5

[0076] Based on the embodiment 1, in the embodiment 1, the position of the entire tool control box 8 together with the tool 10 is fixed and cannot be moved;

[0077] like Figure 6 As shown, in this embodiment, a slide 701 is horizontally arranged from left to right in the middle below the top plate 7 of the box body; a tool control box 8 is movably arranged on the slide 701; the tool control box 8 can move along the X-axis on the slide 701; the tool control box 8 drives the tool 10 below to move together, so as to adjust the position of the tool 10.

[0078] Example 6

[0079] Based on Example 1, in Example 1, the nozzle at the head end of the universal tube 11 for spraying the coolant is set as a common nozzle; the sprayed coolant does not cover a wide range and is not sprayed evenly;

[0080] In this embodiment, a pressurized atomizing nozzle 1101 is provided at the nozzle at the head end of the universal tube 11. The pressurized atomizing nozzle 1101 can be used to form the sprayed coolant into a fine mist, and the spraying range can also be wider, so that the coolant is evenly sprayed on the tool 10 and the part material;

[0081] In addition, the valve on the universal tube 11 is set as an electric control valve 1102, which realizes automatic opening or closing of the valve through electric control; there is no need to open the valve manually; during the processing, the coolant does not need to be sprayed continuously, and the electric control valve 1102 can be opened for spraying as needed, which is more flexible.

[0082] The above-mentioned pressurized atomizing nozzle 1101 and the electric control valve 1102 are both existing products and can be purchased and used directly.

[0083] Example 7

[0084] Based on Example 1, in Example 1, the debris generated by the cutting or grinding of the part material by the tool 10 is taken away by the flushing of the coolant; but sometimes the amount of debris is too much and the discharge is not timely, and some debris may still accumulate on the surface of the workbench 2;

[0085] like Figure 1 As shown, a dust removal pipe 12 passes through one side of the machine tool housing 1; a shaped elbow 1201 is provided at one end of the dust removal pipe 12 located in the machine tool housing 1, and a dust hood is provided at the head end of the shaped elbow 1201; the dust hood should be located close to the tool 10 and the part material;

[0086] One end of the dust removal pipe 12 outside the machine tool housing 1 is connected to the dust removal negative pressure device 1202; the debris generated by the tool 10 during the cutting and grinding of the part material can be sucked out of the machine tool housing 1 under the action of the dust removal pipe 12, and the remaining debris mixed with the coolant is discharged from the collection space under the workbench 2. In this way, the amount of debris on the machine tool housing 1 and the workbench 2 can be minimized.
