[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] The utility model provides Figure 1-5 A driving device shown includes a cylinder body 1 and a dust prevention mechanism 3. The cylinder body 1 is fixedly inserted and connected to the top of the press, and a driving rod 2 is provided inside the cylinder body 1.

[0025] The dustproof mechanism 3 is used to prevent the driving rod 2 from entering the cylinder body 1 and being contaminated with granular impurities and dust. The dustproof mechanism 3 includes an annular groove, which is arranged at the bottom of the cylinder body 1. The inner cavity of the annular groove is provided with a movable ring 301. The inner wall of the annular groove is symmetrically provided with two anti-slip grooves. The inner cavities of the two anti-slip grooves are provided with anti-slip sliders 308 which are slidably sleeved. The anti-slip grooves and the anti-slip sliders 308 are used to prevent the movable ring 301 from escaping from the annular groove, and also ensure that the movable ring 301 can move smoothly. The two anti-slip sliders 308 are symmetrically fixedly connected to the inner wall of the movable ring 301. A plurality of return springs 302 are arranged on the top of the movable ring 301. The return springs 302 can undergo elastic deformation to drive the movable ring 301 to automatically perform a return movement, thereby improving the convenience of operation. A plurality of return springs 302 are fixedly connected to the top of the movable ring 301 in an annular array. The top ends of the plurality of return springs 302 are fixedly connected to the top of the inner wall of the annular groove. A plastic dustproof ring 303 is arranged on the bottom of the movable ring 301. The connection between the plastic dustproof ring 303 and the movable ring 301 and the connection between the plastic dustproof ring 303 and the reduction ring 312 is carried out by means of adhesive, so that the damaged plastic dustproof ring 303 can be easily replaced. An assembly ring 304 is provided at the bottom of the plastic dustproof ring 303, and a reduction ring 312 is sleeved on the outer wall of the assembly ring 304. The reduction ring 312 is fixedly sleeved on the outer wall of the assembly ring 304. The plastic dustproof ring 303 is fixedly connected between the movable ring 301 and the reduction ring 312. A fixed ring 305 is provided below the assembly ring 304 to fix the plastic dustproof ring 303. The top of the fixed ring 305 is symmetrically provided with through holes, and the inner cavities of the two through holes are provided with assembly screws 306. The two assembly screws 306 are symmetrically fixedly connected to the bottom of the assembly ring 304. The outer walls of the two assembly screws 306 are sleeved with locking nuts 307. When the locking nuts 307 are rotated clockwise, the locking nuts 307 on the assembly screws 306 will move toward the direction of the fixed ring 305. The inner walls of the two locking nuts 307 are threadedly connected with the outer walls of the assembly screws 306 corresponding to the positions.

[0026] A cylindrical block 309 is fixedly connected to one side of the cylinder body 1. A threaded hole is provided on one side of the cylindrical block 309. A locking bolt 310 is threadedly connected to the inner wall of the threaded hole. An annular anti-slip groove is provided on the inner wall of the threaded hole. An anti-slip ring 311 is provided in the inner cavity of the annular anti-slip groove. The anti-slip ring 311 is used to prevent the locking bolt 310 from escaping from the threaded hole. The anti-slip ring 311 is fixedly sleeved on the outer wall of the locking bolt 310. A locking hole is provided on the outer wall of the movable ring 301. One end of the locking bolt 310 penetrates the outer wall of the cylinder body 1 and is movably sleeved with the inner cavity of the locking hole. When one end of the locking bolt 310 is inserted into the locking hole, half of the movable ring 301 protrudes out of the annular groove, which is convenient for replacing the plastic dust ring 303.

[0027] The top of the assembly ring 304 is fixedly connected with an annular Velcro 1 4 , and the bottom of the cylinder body 1 is fixedly connected with an annular Velcro 2 5 . The annular Velcro 1 4 and the annular Velcro 2 5 are used for limiting the assembly ring 304 when the dustproof mechanism 3 is not used.

[0028] like Figure 1 As shown, this embodiment provides a press machine, which includes the above-mentioned driving device.

[0029] Working principle of this utility model:

[0030] When using a press to process a workpiece, first apply a vertical downward force to the assembly ring 304 until the annular Velcro 1 4 is separated from the annular Velcro 2 5, and then place the assembly ring 304 on the top of the fixing ring 305. During this process, the two assembly screws 306 need to be inserted into the corresponding through holes, and then the two locking nuts 307 are screwed on the corresponding assembly screws 306 until the assembly ring 304 cannot shake easily. At this time, the assembly of the dustproof mechanism 3 is completed. During the movement of the driving rod 2, the plastic dustproof ring 303 will move synchronously with the driving rod 2, thereby preventing the driving rod 2 from entering the cylinder body 1 and being contaminated with granular impurities and dust, avoiding damage to the internal components of the cylinder body 1, and ensuring the accuracy of the components in the cylinder body 1.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
