[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a CNC lathe power head with a protective structure, including a power head body 1, a spring chuck 2 is fixedly installed on the side wall of the power head body 1, the spring chuck 2 is specifically an ER chuck, model ER25, an empty slot 3 is opened on the power head body 1, and a protective mechanism 4 for protecting the spring chuck 2 is arranged on the power head body 1. The spring chuck 2 can be protected by setting the protective mechanism 4 to prevent iron filings from splashing into the interior of the spring chuck 2 during the operation of the CNC machine tool. A cleaning mechanism 5 for cleaning the spring chuck 2 is arranged on the protective mechanism 4. The cleaning mechanism 5 can adsorb fine metal particles on the inner wall of the spring chuck 2 to prevent the accumulation of metal particles and the inability to install the turning tool.

[0024] The protective mechanism 4 includes an L-rod 41, a baffle 42, a worm 43, a worm gear 44, a slider 45, and a knob 46; one end of the L-rod 41 is rotatably connected to the inner wall of the slot 3, and the other end of the L-rod 41 penetrates the power head body 1 and is rotatably connected to the slider 45. The slider 45 can be pushed and pulled by the rotation of the L-rod 41, so that the slider 45 can slide up and down on the side wall of the baffle 42 while pushing and pulling the baffle 42. The outer wall of the L-rod 41 is fixedly mounted with a worm gear 44, and the baffle 42 is slidably connected to the power head body. 1, and the opening of the spring chuck 2 is completely covered by the baffle plate 42, so that iron filings can be prevented from splashing into the interior of the spring chuck 2 during the operation of the CNC machine tool. The slider 45 is slidably connected to the side wall of the baffle plate 42, one end of the worm 43 is rotatably connected to the inner wall of the slot 3, and the other end of the worm 43 is fixedly mounted with a knob 46, the worm 43 is meshed with the worm wheel 44, and the worm 43 is rotated by the knob 46, and the L rod 41 can be driven to rotate by the rotation of the worm 43 and the worm wheel 44 meshed with it.

[0025] The cleaning mechanism 5 comprises a collar 51, a slide plate 52, a magnetic rod 53, an iron plate 54 and a torsion spring 55; the collar 51 is hinged on the outer wall of the baffle 42. When it is necessary to clean the fine metal particles inside the spring chuck 2, the collar 51 is first rotated 180° so that the magnetic rod 53 is located at the opening of the spring chuck 2. The inner wall of the collar 51 is slidably connected with the slide plate 52, and the inner wall of the slide plate 52 is hinged with the magnetic rod 53. The slide plate 52 is pushed so that the slide plate 52 drives the magnetic rod 53 to make a circular motion on the inner wall of the collar 51. At this time, the The magnetic rod 53 can be used to absorb the fine metal particles on the inner wall of the spring chuck 2. The outer wall of the baffle 42 is fixedly installed with an iron plate 54. The ring 51 is rotated to make the magnetic rod 53 and the iron plate 54 absorb together. At this time, the ring 51 can be limited by using the magnetic rod 53 and the iron plate 54. A torsion spring 55 is provided at the hinge between the magnetic rod 53 and the slide plate 52. After cleaning, the magnetic rod 53 is released. At this time, the elasticity of the torsion spring 55 can drive the magnetic rod 53 to rotate and reset, so that the magnetic rod 53 and the slide plate 52 can be kept parallel.

[0026] Working principle: when the spring chuck 2 is not installed with the turning tool, the worm 43 is rotated by the knob 46, and the rotation of the worm 43 and the worm wheel 44 meshing therewith can drive the L rod 41 to rotate, and the rotation of the L rod 41 can push the slider 45, so that the slider 45 slides downward on the side wall of the baffle 42 and pushes the baffle 42 at the same time, so that the baffle 42 slides toward the side close to the spring chuck 2 until the baffle 42 covers the entire opening of the spring chuck 2. At this time, the baffle 42 can be used to protect the spring chuck 2 to prevent iron filings from splashing into the interior of the spring chuck 2 during the operation of the CNC machine tool.

[0027] When it is necessary to clean the fine metal particles inside the spring chuck 2, the ring 51 is first rotated 180° so that the magnetic rod 53 is located at the opening of the spring chuck 2, and then the magnetic rod 53 is pushed to rotate it toward the inside of the spring chuck 2. At the same time, the magnetic rod 53 will compress the torsion spring 55, so that the magnetic rod 53 and the slide plate 52 remain vertical, and then the slide plate 52 is pushed again, so that the slide plate 52 drives the magnetic rod 53 to make a circular motion on the inner wall of the ring 51. At this time, the magnetic rod 53 can be used to absorb the fine metal particles on the inner wall of the spring chuck 2 to avoid the accumulation of metal particles causing the turning tool to be unable to be installed. After the cleaning is completed, the magnetic rod 53 is released. At this time, the elasticity of the torsion spring 55 can drive the magnetic rod 53 to rotate and reset, so that the magnetic rod 53 and the slide plate 52 remain parallel, and then the ring 51 is rotated to make the magnetic rod 53 and the iron plate 54 adsorbed together. At this time, the ring 51 can be limited by the magnetic rod 53 and the iron plate 54.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
