[0027] Example

[0028] Reference Figure 1-Figure 3 The utility model provides a technical solution: a special machine tool for CNC needle groove processing, including a bed 1 and a grooving mechanism 3, and a column 2 is installed on the top of the bed 1, the grooving mechanism 3 includes a vertical slide 31, the vertical slide 31 is movably installed inside the column 2, and a fine milling blade 311 and a rough milling blade 312 are installed inside the vertical slide 31, a dividing plate 32 is rotatably installed on the bed 1, and a tooling shaft 321 is provided on the dividing plate 32 for mounting a workpiece, a connecting beam 33 is fixedly installed on the top of the column 2, and a hydraulic top 331 is installed on the top of the connecting beam 33, and the telescopic end of the hydraulic top 331 is arranged at a position inside the connecting beam 33 for limiting the tooling shaft 321.

[0029] In a preferred embodiment, two first cylinders 4 are installed inside the vertical slide 31, and the telescopic end of one of the first cylinders 4 is stably installed with a fine milling cutter seat 5, and the fine milling blade 311 is installed on the fine milling cutter seat 5, and the telescopic end of the other first cylinder 4 is stably installed with a rough milling cutter seat 6, and the rough milling blade 312 is installed on the rough milling cutter seat 6. In order to facilitate the processing of the workpiece, this device installs the fine milling blade 311 on the telescopic end of the first cylinder 4, and also installs the rough milling blade 312 on the telescopic end of the other first cylinder 4, so as to control the movement of the fine milling blade 311 and the rough milling blade 312, thereby processing the workpiece.

[0030] In a preferred embodiment, a second cylinder 7 is also installed on the top of the bed 1, and the telescopic end of the second cylinder 7 is fixedly connected to the vertical slide 31, which is used to control the up and down movement of the fine milling blade 311 and the rough milling blade 312. When cutting grooves on the outer surface of the workpiece, in actual use, it is necessary to control the up and down movement of the fine milling blade 311 and the rough milling blade 312 to process the outer surface of the workpiece to the required length. Therefore, a second cylinder 7 is installed on the bed 1, and the telescopic end of the second cylinder 7 is fixedly connected to the vertical slide 31, thereby driving the fine milling blade 311 and the rough milling blade 312 to move up and down to meet production needs.

[0031] In a preferred embodiment, two vertical slides 31 are provided and are respectively arranged at positions inside the two columns 2. A fine milling blade 311 and a rough milling blade 312 are installed inside each vertical slide 31. In order to improve the processing effect, the device is respectively provided with vertical slides 31 inside the two columns 2, and a fine milling blade 311 and a rough milling blade 312 are installed inside each vertical slide 31. When processing the workpiece, the left and right sides of the workpiece will be processed at the same time, which greatly shortens the processing time.

[0032] The workpiece is cut by the fine milling blade 311 and the rough milling blade 312, and a certain amount of heat is generated during the cutting process. If the heat is not dissipated in time, the service life of the blade and the quality of the workpiece will be reduced. Therefore, a cooling mechanism 8 is installed on the connecting beam 33. The cooling mechanism 8 includes a water bag 81, an outlet pipe 82 and an inlet pipe 83. The water bag 81 is stably installed at the top position inside the connecting beam 33, and the outlet pipe 82 is installed on the lower surface of the water bag 81. The inlet pipe 83 is installed on the upper surface of the water bag 81. The inlet pipe 83 extends out of the interior of the connecting beam 33. The position of the water bag 81 corresponds to the position of the vertical drag plate 31, and a one-way valve 9 is installed on the inlet pipe 83 and the outlet pipe 82 respectively.

[0033] In actual use, when the workpiece is processed by the fine milling blade 311 and the rough milling blade 312, high temperature will be generated. The high temperature will affect the life of the blade and the quality of the workpiece. Therefore, a water bag 81 is installed at the top position of the connecting beam 33. When the vertical drag plate 31 is controlled to move upward, the water bag 81 will be squeezed, and the cutting fluid inside the water bag 81 will be squeezed out from the inside of the water outlet pipe 82, and the cutting fluid will be sprayed to the processing position of the workpiece to cool the processing position, reduce the temperature of the blade and the workpiece, extend the service life of the blade and improve the processing quality of the workpiece.

[0034] Specifically, the working process or working principle of the CNC needle groove processing special machine tool is as follows: the current way to process the needle groove of the workpiece is to place it on a horizontal machine tool and install a four-axis machining, and use a milling cutter to process the groove one by one. Since there will be rough processing and fine processing during processing, it is necessary to first perform rough processing on the workpiece and then perform fine processing on the workpiece. Such operation is very time-consuming and reduces work efficiency, so this device is designed to solve this problem.

[0035] The present device sets two fine milling blades 311 and two rough milling blades 312 respectively. When processing the needle groove on the workpiece, the fine milling blade 311 and the rough milling blade 312 can be controlled to process both sides of the workpiece at the same time, thereby shortening the processing time and improving work efficiency. The specific operation is to connect the external power supply, sleeve the workpiece on the tooling shaft 321, and stably install the tooling shaft 321 on the indexing plate 32. After the tooling shaft 321 is stably installed, the hydraulic center 331 can be opened, and the telescopic end of the hydraulic center 331 is extended and pressed against the tooling shaft 321, so that the tooling shaft 321 can be squeezed and limited. The workpiece processed by the present device is in the shape of a sleeve, which is clamped on the tooling shaft 321 to stably process the workpiece.

[0036] When processing the workpiece, first turn on the first cylinder 4. Since two first cylinders 4 are arranged inside each vertical slide 31, the rough milling blade 312 and the fine milling blade 311 will be pushed to move in turn by the two first cylinders 4, and the device sets two rough milling blades 312 and fine milling blades 311 respectively. When processing the workpiece, the left and right sides of the workpiece can be processed at the same time. After the workpiece is processed by the rough milling blade 312, it is processed by the fine milling blade 311. While processing the workpiece, the second cylinder 7 needs to be turned on, and the telescopic end of the second cylinder 7 drives the vertical slide 31 to move up and down, so that the outer side of the workpiece can be processed into a needle groove shape.

[0037] After grooving the workpiece, the position of the workpiece needs to be changed. The device is equipped with a drive motor inside the bed 1. The drive motor drives the dividing plate 32 to rotate. The rotation of the dividing plate 32 drives the tooling shaft 321 to rotate, thereby driving the workpiece to rotate and changing the processing position of the workpiece, so as to continue processing the workpiece according to the above method.

[0038] When the workpiece is processed by the fine milling blade 311 and the rough milling blade 312, high temperature will be generated. The high temperature will affect the life of the blade and the quality of the workpiece. Therefore, a water bag 81 is installed at the top position of the connecting beam 33. When the vertical drag plate 31 is controlled to move upward, the water bag 81 will be squeezed, and the cutting fluid inside the water bag 81 will be squeezed out from the inside of the water outlet pipe 82, and the cutting fluid will be sprayed to the processing position of the workpiece to cool the processing position, reduce the temperature of the blade and the workpiece, extend the service life of the blade and improve the processing quality of the workpiece.

[0039] It should be noted that the first cylinder 4 and the second cylinder 7 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
