DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 10 , a laser engraving precision machining machine tool, comprising: a machine tool table 1, a processing space is opened in the middle of the machine tool table 1;

[0036] A rotating assembly 2 is arranged inside the processing space, and the rotating assembly 2 is used to place and rotate mechanical parts. The rotating assembly 2 includes a rotating shaft 21 and a rotating shell 22. The rotating shaft 21 is rotatably connected to the bottom surface of the rotating shell 22, and a plurality of mounting openings are annularly opened on the rotating shell 22;

[0037] A plurality of placement components 3 are arranged inside the plurality of installation ports, and the placement components 3 include a placement tube 31, a sliding rod 32 and a placement plate 33. The placement tube 31 is fixedly installed inside the installation port, a sliding port is opened at the bottom of the placement tube 31, and the sliding rod 32 is slidably arranged inside the sliding port. The placement plate 33 is fixedly connected to the upper end of the sliding rod 32 and is slidably arranged inside the placement tube 31. A powder guide ring groove is opened in an annular shape in the middle of the placement tube 31, and the placement plate 33 is located on the upper side of the powder guide ring groove.

[0038] An injection assembly 4 is arranged between the placement tube 31 and the rotating assembly 2. The injection assembly 4 includes an airbag 41, a sealing ring 42 and an extrusion block 43. An air port is opened on the side of the placement tube 31. The sealing ring 42 is fixedly connected to the side of the placement plate 33 for sealing the air port position. The airbag 41 is fixedly connected to the side of the placement tube 31 and is connected to the air port. The extrusion block 43 is fixedly connected to the side of the rotating shaft 21. When the placement tube 31 rotates, the extrusion block 43 squeezes the airbag 41 to spray air above the placement plate 33.

[0039] In the embodiment of the application of the above technical solution, during the processing, the parts are placed on the placement plate 33, and during the rotation, they are moved to the inside for laser processing. During the processing, the placement tube 31 drives the airbag 41 to rotate, so that the extrusion block 43 squeezes the airbag 41, so that the gas inside the airbag 41 is sprayed from the air port to the inside of the placement plate 33, and the inside of the placement tube 31 is cleaned. After the processing is completed, a large amount of debris will pass through the inside of the placement tube 31 and be transferred to the airbag 41 and separated from the extrusion block 43, so that the airbag 41 is restored by suction, and the generated debris is collected and introduced into the placement tube 31 from the powder guide ring groove, so that the debris is collected. The present invention can collect and clean the debris during the processing, thereby ensuring the precision of the processing.

[0040] In the preferred technical solution of this embodiment, a limiting component 5 is arranged on the placement plate 33, and the limiting component 5 is used to limit the position of the parts placed on the placement plate 33. During the engraving process, in order to ensure the engraving effect of the parts, the position of the parts needs to be limited and fixed during the engraving process. The parts are limited by the limiting component 5, thereby ensuring the engraving effect;

[0041] The limiting assembly 5 includes a telescopic rod 51, a top plate 52, and an extrusion limiting capsule 53. The telescopic rod 51 is vertically fixedly connected to the middle of the placement plate 33, and the top plate 52 is fixedly connected to the upper end of the telescopic rod 51. The top plate 52 is annularly provided with a plurality of limiting openings. The plurality of limiting extrusion capsules are all L-shaped, fixedly installed under the top plate 52, and clamped inside the limiting openings. The extrusion limiting capsule 53 is deformed by extrusion and is located at the limiting opening part, and is extruded upward. When a part is placed on the top plate 52, due to the effect of gravity, the top plate 52 squeezes the extrusion limiting capsule 53, thereby deforming the extrusion limiting capsule 53. The position of the part is limited by the deformed extrusion limiting capsule 53, thereby ensuring the precise processing of the part.

[0042] The rotating assembly 2 further includes a rotating ring 23 and an installation box 24. The installation box 24 is fixedly installed inside the processing space. The placement plate 33 has a C-shaped cross section. The rotating ring 23 is sleeved on the rotating shell 22 and is rotatably arranged inside the installation box 24. During the processing, multiple parts are placed inside multiple placement assemblies 3, and the rotating shell 22 is driven to rotate by the rotating ring 23, so that the multiple placement assemblies 3 are rotated to transfer the internal parts, thereby ensuring the adjustment of the position of the parts.

[0043] The mounting box 24 is provided with a positioning assembly 6, which is used to adjust the position of the placement plate 33 inside the placement tube 31. In order to ensure effective blocking of the debris transmitted during the processing of the parts, the parts are adjusted by the positioning assembly 6.

[0044] The positioning assembly 6 includes a downward moving sealing block 61, a lifting sealing block 62, a linkage sealing block 63 and a connecting rod 64. A liquid guiding pipe is provided inside the installation box 24. The liquid guiding pipe is set in a U shape, and the two ends are respectively arranged on the opening surface and the bottom surface of the processing space. The downward moving sealing block 61 is sealingly slidably arranged at one end of the liquid guiding pipe close to the bottom surface of the processing space, and the lifting sealing block 62 is sealingly slidably arranged at one end of the liquid guiding pipe close to the opening of the processing space. The side of the liquid guiding pipe close to the bottom surface of the processing space is connected to an L-shaped conduit, and the L-shaped conduit is connected to the liquid guiding pipe. The linkage sealing block 63 is sealingly slidably arranged inside the conduit, and the connecting rod 64 is fixedly connected between the downward moving sealing block 61 and the linkage sealing block 63. The space is used to drive the downward seal block 61 to move downward. When the placement component 3 for placing the parts moves to the top of the downward seal block 61, the linkage seal block 63 will move downward during the processing, thereby driving the connecting rod 64 and the downward seal block 61 to move downward. The downward seal block 61 causes the sliding rod 32 to move downward, so that the placement plate 33 moves downward inside the placement tube 31, thereby ensuring that during the processing, the debris generated by the parts will accumulate inside the placement tube 31, avoiding the scattering of the debris. At the same time, during the downward movement of one end, the lifting seal block 62 on the other side is lifted up through the liquid guide pipe, thereby lifting up the parts processed at the other end, thereby ensuring the rapid transfer of the parts.

[0045] A laser assembly 7 is arranged inside the processing space. The laser assembly 7 is used for laser engraving parts. The laser assembly 7 includes a control module 71, a control column 72 and a laser head 73. The control module 71 is fixedly mounted on the side wall of the machine tool table 1, the control column 72 is fixedly connected below the control module 71, and the laser head 73 is fixedly mounted on the bottom surface of the control column 72. The position of the control column 72 is adjusted by the control module 71 to drive the laser head 73 to move, thereby ensuring the precision processing of the parts.

[0046] The sliding rod 32 is sleeved with an extrusion ring 8, which is fixedly connected to the bottom of the placement plate 33 through an elastic tube. The extrusion ring 8 will squeeze the debris when the placement plate 33 moves downward, thereby increasing the collection space of the debris inside the placement tube 31, collecting more debris, and extending the cleaning cycle;

[0047] A side block 9 is fixedly connected to the side of the control column 72. An elastic rod 10 is fixedly connected between the side block 9 and the linkage sealing block 63. The linkage sealing block 63 is driven downward by the elastic rod 10 to ensure the normal use of the adjustment component 6.
