[0002] In certain precision manufacturing fields, extremely high precision requirements are placed on parts, especially in terms of surfaces, outer circles, and other features that require grinding and milling. In this case, if only a single grinder or milling machine is used for processing, the parts will need to be clamped twice during processing, which often leads to processing errors. As a result, the accuracy of the parts cannot meet the design requirements, thus affecting the quality of the entire workpiece. In addition, for certain specific parts, multiple machine tools are required for processing, which not only leads to a significant increase in the floor space of the production site, but also brings a series of other problems. First, workers need to spend extra time on the handling and loading and unloading of workpieces, and this extra working time directly affects processing efficiency.

DETAILED DESCRIPTION

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1-6 , the utility model provides a crankshaft milling machine, comprising a machine tool base 1;

[0030] A clamping device 2, the clamping device 2 is used to clamp the workpiece to fix its position;

[0031] A milling and grinding machine 3, comprising a milling column 30 movably mounted on the machine base 1, a milling side plate 31 movably mounted on the milling column 30, a milling cutter device 32 fixedly mounted on the milling side plate 31, and a sharpening device 33, wherein the milling cutter device 32 is horizontally mounted above the sharpening device 33;

[0032] a first moving device 4 , which is laterally fixed to the machine tool base 1 and is used to laterally move the milling column 30 toward or away from the workpiece;

[0033] The second moving device 5 is longitudinally fixed on the milling column 30 and is used to longitudinally move the milling side plate 31 so that the milling cutter device 32 or the grinding device 33 provided thereon can process a workpiece.

[0034] In the above structure, the staff clamps the workpiece on the clamping device and then starts the displacement of the first moving device. The first moving device drives the milling column to move horizontally so that the milling machine is close to the workpiece, so that the workpiece is located in the gap between the milling cutter device and the grinding device, and then controls the second moving device to move up and down longitudinally according to the way the workpiece needs to be processed. When the workpiece needs to be processed using the milling cutter device, the second moving device drives the milling column downward, and the milling cutter device is close to the workpiece for processing; when the workpiece needs to be processed using the grinding device, the second moving device drives the milling column upward, and the grinding device is close to the workpiece for processing. The whole process is carried out by the moving device, and no human is required for secondary clamping, which prevents the occurrence of errors in secondary clamping. At the same time, it saves the workers' time in carrying and loading and unloading workpieces, thereby improving processing efficiency.

[0035] Specifically, a thimble seat 34 is fixedly provided on one side of the milling and grinding machine 3, and a thimble 36 driven by a cylinder 35 is provided on the thimble seat 33. The thimble 36 is arranged in the gap between the milling cutter device 32 and the grinding device 33, and corresponds to the position of one end of the workpiece. Using the thimble to support the workpiece to be processed can support the workpiece, fix the workpiece to prevent displacement, and ensure that the workpiece can be processed stably.

[0036] Specifically, the machine tool base 1 is covered with a machine tool sheet metal shell shield 10, which can prevent dust, debris and other debris from entering the interior of the machine tool, thereby extending the service life of the machine tool. Covering the internal machine tool can protect the safety of the operator when the machine tool is working, and at the same time can cover the internal machine tool to improve the overall aesthetics of the machine.

[0037] Specifically, the first moving device 4 includes a first guide rail 40 symmetrically arranged on the machine tool base 1, a first slider 41 fixed to the bottom of the milling column 30, and a first driving device 42 fixed between the first guide rails 40.

One side of the first nut 422 is fixedly connected to the bottom of the milling column 30. The screw rod and the nut have a small clearance, are easy to rotate, have a long service life, and have high precision and high efficiency. At the same time, the screw rod and the nut have a high bearing capacity, and have a strong power output when driven by the driving motor.

[0039] Specifically, the second moving device 5 includes a second guide rail 50 symmetrically arranged on the milling side plate 31, a second slider 51 fixed to the side of the milling column 30, and a second driving device 52 arranged on the milling column 30. The second slider 51 is used in conjunction with the second guide rail 50, and the driving device is used to drive the movement of the milling side plate, and then the cooperation between the second guide rail and the second slider plays a role of limiting guidance.

[0040] Specifically, the second driving device 52 includes a second driving motor 520, a second screw rod 521 rotatably arranged at one end of the second driving motor 520, and a second nut 522 movably arranged on the second screw rod 521. One side of the second nut 522 is fixedly connected to the side of the milling side plate 31. The screw rod and the nut have a small clearance, are easy to rotate, have a long service life, and have high precision and high efficiency. At the same time, the screw rod and the nut have a high bearing capacity, and have a strong power output when driven by the driving motor.

[0041] Specifically, the machine tool base 1 is movably provided with a chip conveyor 6, and a dust collector 7 used in conjunction with the chip conveyor 6 is placed on one side of the chip conveyor 6. The integrated design allows the chip conveyor to absorb the debris generated by processing as soon as possible, effectively reducing the flying of debris and thus reducing pollution.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
