[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] Embodiment 1

[0025] Combined with Figure 1-4 The utility model provides a special clamp for a CNC lathe, including a chuck body 1, a movable claw 2, and a driving rod 3. A plurality of movable claws 2 are slidably connected to one side of the chuck body 1, and the driving rod 3 is rotatably connected to the side of the chuck body 1. The driving rod 3 is adjusted to make the movable claw 2 clamp the workpiece. A through hole 11 with a circular hole structure is opened at the center of the chuck body 1. A cleaning mechanism 4 is inserted into the inner side of the chuck body 1. The chuck body 1 is located at a side opposite to the movable claw 2 and is movably connected to a collecting mechanism 5. The cleaning mechanism 4 includes a cleaning rod 41, a connecting disk 42, a cleaning pad 43, a connecting rod 44, and a magnetic suction cup 45. The lower end of the cleaning rod 41 is fixedly connected to the connecting disk 42, and the cleaning pad 43 is fixedly connected to the connecting disk 42. On the outside, both ends of the connecting rod 44 are connected to the connecting disk 42 and the magnetic suction cup 45 respectively. The outer diameter of the cleaning pad 43 is adapted to the through hole 11 of the chuck body 1. Before clamping the workpiece, the cleaning rod 41 is pulled out of the through hole 11 for use. When the chuck body 1 is finished using, the cleaning rod 41 is held and one end of its connecting disk 42 is inserted into the through hole 11 and pushed downward. During this process, the magnetic suction cup 45 absorbs the iron filings on the inside of the through hole 11, and the cleaning pad 43 wipes off the remaining iron filings to separate them from the inside of the through hole 11. After falling, they are absorbed by the magnetic suction cup 45 or fall into the collecting mechanism 5, and then the cleaning rod 41 is pulled out to clean it. It can be used multiple times to enhance the cleaning effect.

[0026] Embodiment 2

[0027] Combined with Figure 1-4On the basis of the first embodiment, the chuck body 1 is located at the side opposite to the movable claw 2 and is fixedly connected with a base 12 adapted to the chuck body 1. The collecting mechanism 5 includes a slide rail 51 and a collecting bucket 52. Two symmetrical slide rails 51 are arranged on both sides of the base 12. The upper end of the collecting bucket 52 is adapted to the slide rail 51. A sliding member 53 is arranged on the upper end of the collecting bucket 52. The shapes of the two sides of the sliding member 53 are adapted to the slide rail 51. Before cleaning, the collecting bucket 52 can be slid on the slide rail 51 to the through hole 11 to collect iron filings. After cleaning, the collecting bucket 52 can be slid out. The radius of the magnetic suction cup 45 is smaller than the through hole 11 to avoid hard friction between the iron filings and the magnetic suction cup 45 and the inner side of the through hole 11, which may cause damage to the magnetic suction cup 45 and the chuck body 1. The length of the cleaning rod 41 is greater than the depth of the through hole 11. A lifting ring 46 is fixedly connected to the upper end of the cleaning rod 41 to facilitate cleaning of the through hole 11 in the chuck body 1.

[0028] The working principle of this application is:

[0029] Before clamping the workpiece, the cleaning rod 41 is pulled out of the through hole 11 for use. When the chuck body 1 is cleaned after clamping, the cleaning rod 41 is held and one end of the connecting plate 42 is inserted into the through hole 11 and pushed downward. In this process, the magnetic suction cup 45 absorbs the iron filings inside the through hole 11, and the cleaning pad 43 wipes the remaining iron filings to separate them from the inside of the through hole 11. After falling, they are absorbed by the magnetic suction cup 45 or fall into the collection bucket 52. The upper end of the collection bucket 52 is provided with a sliding member 53, and both sides of the sliding member 53 are The shape is adapted to the slide rail 51. After cleaning, the collecting bucket 52 can be slid on the slide rail 51 to remove the internal iron filings, and then the cleaning rod 41 can be pulled out to clean the cleaning rod 41. It can be used multiple times to enhance the cleaning effect. The patent uses the magnetic suction cup 45 to absorb the iron filings on the inner wall of the through hole 11 of the chuck body 1, and the cleaning pad 43 wipes off the remaining iron filings on the inner wall of the through hole 11, and collects the iron filings through the collecting mechanism 5, so as to simply and efficiently clean the iron filings in the chuck body 1, while effectively ensuring the cleaning effect.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
