[0031] Example 1

[0032] Combine Figures 1 to 5 A head fixing device of a CNC engraving machine includes a machine plate 3 and a machine length plate 5, the bottom of the machine length plate 5 is fixedly connected to an organic needle head 1, a stabilizing mechanism 4 is provided on the machine length plate 5 and the machine plate 3, and a mounting mechanism 2 is provided on the stabilizing mechanism 4;

[0033] The stabilizing mechanism 4 includes a clamping component 41 and a stabilizing component 42 , wherein the stabilizing component 42 is disposed on the clamping component 41 ;

[0034] The clamping assembly 41 includes a slot 413, which is opened at the bottom of the machine plate 3. The bottom of the slot 413 is set as an opening. The surface of the machine plate 5 is plugged into the slot 413. The left and right sides of the machine plate 3 are fixedly connected with fixed plates 418. The fixed plates 418 have rectangular grooves 412 formed inside. The inner walls of the rectangular grooves 412 have sliding grooves 417 on the front and rear sides. The sliders 414 are slidably connected inside the sliding grooves 417. A movable plate 419 is fixedly connected between the front and rear sliders 414. The lower end of the movable plate 419, which is close to the machine plate 3, is fixedly connected to a fixing seat 4101. The other side of the fixing seat 4101 is fixedly connected to a clamping plate 411. The clamping plate 411 is arranged on the surface of the machine length plate 5. The top of the fixed plate 418, which is away from the machine plate 3, is fixedly connected to a limit block 416. An electric push rod 415 is fixedly connected between the limit block 416 and the movable plate 419. The top and bottom of the rectangular groove 412 are both set to be open, and the surface of the movable plate 419 and the interior of the rectangular groove 412 are plugged into each other.

[0035] The stabilizing assembly 42 includes a T-slot 427, which is provided inside the movable plate 419 on the side close to the machine plate 3. A T-block 426 is slidably connected inside the T-slot 427. A mounting base 421 is fixedly connected to the T-block 426 on the side close to the machine plate 3. A rotating rod 422 is fixedly connected to the other side of the mounting base 421. A rotating plate 425 is rotatably connected to the surface of the rotating rod 422. A square slot 423 is provided on the front of the fixing base 4101. Bolts 424 are threadedly connected to the inside of the rotating plate 425 and the fixing base 4101. The front, top and bottom of the square slot 423 are all set to be open, and the surface of the rotating plate 425 and the inside of the square slot 423 are plugged into each other.

[0036] Furthermore, the electric push rod 415 drives the movable plate 419 to move when it is running. When the movable plate 419 moves, on the one hand, it can drive the slider 414 to slide in the slide groove 417. On the other hand, the movable plate 419 drives the fixed seat 4101 to move. The fixed seat 4101 drives the clamping plate 411 to move out from one side of the captain plate 5, so that the captain plate 5 can be replaced directly and conveniently. The rotating plate 425 is inserted into the square groove 423, so that when the clamping plate 411 clamps and fixes the captain plate 5, it can avoid the fixed seat 4101 and the movable plate 419 from breaking to a certain extent.

[0037] Example 2

[0038] See Figure 1-7, and on the basis of the first embodiment, the mounting mechanism 2 further comprises a long slot 27, the long slot 27 being provided at the upper and lower ends of the front face of the machine long plate 5, the front face of the long slot 27 being set as an opening, a long plate 26 being inserted into the long slot 27, the upper and lower long plates 26 being fixedly connected to the front faces of the connecting plates 25, the left and right sides of the connecting plates 25 being fixedly connected to locking plates 24, the other side of the locking plate 24 being hinged to a hinge plate 23, the hinge plate 23 being fixedly connected to a clamping block 21 on the side close to the machine plate 3, and a clamping slot 22 being provided on the left and right sides of the machine plate 3;

[0039] Through slots are provided at both upper and lower ends of the front face of the machine board 3. The surface of the long board 26 is inserted into the through slots provided at both upper and lower ends of the front face of the machine board 3. There are four card blocks 21 and card slots 22 in number and they form a group of two. The openings of the card slots 22 on the left and right sides are opened corresponding to each other, and the surface of the card block 21 and the inside of the card slot 22 are engaged.

[0040] Furthermore, the hinged plate 23 drives the card block 21 out of the card slot 22, and the connecting plate 25 is pulled again to drive the long plate 26 out of the long slot 27, so that the initial limit fixation of the position of the machine long plate 5 can be cancelled, so that the machine long plate 5 can be pulled out of the slot 413 with the cooperation of the stabilizing mechanism 4 in the later stage, so that the machine needle head 1 can be replaced in the later stage.

[0041] In actual operation, when this device is used, when the needle head 1 needs to be replaced according to the pattern to be engraved, first, the hinge plate 23 is rotated on one side of the locking plate 24, so that the hinge plate 23 and the locking plate 24 are in a straight line. The hinge plate 23 can drive the card block 21 to be taken out from the card slot 22, and then the connecting plate 25 is pulled again to drive the long plate 26 to be taken out from the long slot 27, so that the initial limit fixation of the position of the machine long plate 5 can be cancelled, so that the machine long plate 5 can be pulled out from the slot 413 with the cooperation of the stabilizing mechanism 4 in the later stage, so that the needle head 1 can be replaced in the later stage.

[0042] When the electric push rod 415 is running, the movable plate 419 is driven to move. When the movable plate 419 moves, on the one hand, it can drive the slider 414 to slide in the slide groove 417. On the other hand, the movable plate 419 drives the fixed seat 4101 to move. The fixed seat 4101 drives the clamping plate 411 to move out from the side of the captain plate 5, so that the captain plate 5 can be replaced directly and conveniently.

[0043] When the rotating plate 425 rotates on the surface of the rotating rod 422 until the rotating plate 425 is inserted into the square groove 423, the bolt 424 threadedly fixes the rotating plate 425 and the fixed seat 4101, so that when the clamping plate 411 clamps the captain plate 5, the fixed seat 4101, the movable plate 419 and the rotating plate 425 cooperate to avoid the fixed seat 4101 and the movable plate 419 from breaking to a certain extent.

[0044] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
