[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] For example 1, please refer to Figure 1-Figure 3 The present invention provides a technical solution: a laser marking machine for a hydraulic valve seat, comprising a working plate 1, a sliding groove 2 being formed on the top of the working plate 1, protective plates 3 being fixedly connected to both sides of the working plate 1, a marking mechanism 5 being provided on the inner wall of the sliding groove 2, and the marking mechanism 5 being provided on the inner side of the protective plate 3, and further comprising: The fixing mechanism 4 includes a placement plate 401 fixedly connected to the top of the working plate 1, a gasket 403 fixedly connected to the bottom of the inner wall of the placement plate 401, a compression ring slidably connected to the top of the gasket 403, and the interior of the gasket 403 is filled with coolant. When the compression ring is pressed by the valve seat, it will drive the compression ring to shrink inward into the interior of the gasket 403, thereby compressing the coolant inside it and discharging the coolant into the adsorption plate 405. A telescopic foot 404 is fixedly connected to the surface of the gasket 403, and the end of the telescopic foot 404 away from the gasket 403 is fixedly connected to the adsorption plate 405. The adsorption plate 405 is fixedly connected to the top of the placement plate 401, and a movable groove 402 is provided on the top of the placement plate 401, and an absorption component 406 is provided on the inner wall of the movable groove 402.

[0022] The absorption component 406 includes a fixed block 4061 which is slidably connected to the bottom of the inner wall of the movable groove 402 through a slider, a telescopic chamber 4063 is fixedly connected to the right side of the fixed block 4061, an adsorption ring 4064 is slidably connected to the inner wall of the telescopic chamber 4063, a contact foot 4068 is fixedly connected to the top of the telescopic chamber 4063, a collection membrane 4066 is fixedly connected to the bottom of the inner wall of the contact foot 4068, a negative pressure chamber is provided inside the contact foot 4068, and when subjected to external pressure, the negative pressure chamber will shrink inward to reduce the space and form a pressure difference with the outside, thereby generating negative pressure suction which is transmitted into the internal cavity of the collection membrane 4066, a push rod 4065 is fixedly connected to one end of the collection membrane 4066 away from the bottom of the inner wall of the contact foot 4068, and the push ring 4062 is fixedly connected to the left side of the fixed block 4061.

[0023] The working method of the first embodiment is as follows: the hydraulic valve seat is first placed on the top of the placement plate 401. The bottom of the hydraulic valve seat will generate pressure on the top of the gasket 403. When the compression ring on the top of the gasket 403 is pressed, the compression ring will expand and contract inward into the interior of the gasket 403. After the internal space of the gasket 403 is compressed, the coolant inside it will be ejected from the jet disk on the inner wall of the adsorption plate 405, thereby cooling the bottom of the hydraulic valve seat. When the laser is marking the surface of the hydraulic valve seat, the impact on the surface of the hydraulic valve seat will cause it to shake. When the surface of the hydraulic valve seat shakes, it will press the compression ring on the top of the gasket 403 multiple times, thereby continuously compressing the coolant inside the gasket 403, and thus ejecting it multiple times in the jet disk. When the laser is marking the surface of the hydraulic valve seat, the heat generated will be concentrated in the bottom in large quantities, and the ejected coolant will cool the heat generated on the surface of the hydraulic valve seat due to laser marking, ensuring the cooling effect of the mark printed on the surface of the hydraulic valve seat. When the hydraulic valve seat is placed on the top of the placement plate 401, the push ring 4062 is pulled to drive the fixed block 4061 to slide inward on the inner wall of the sliding groove 2. When the fixed block 4061 moves to the surface of the hydraulic valve seat, the surface of the hydraulic valve seat is adsorbed and fixed by the adsorption ring 4064. At this time, the collection film 4066 will come into contact with the surface of the hydraulic valve seat. When the laser is marking the surface of the hydraulic valve seat, the surface of the hydraulic valve seat will shake. The resulting shaking will push the push rod 4065, driving one end of the push rod 4065 to extend and retract toward the inside of the contact foot 4068. When the inside of the contact foot 4068 is compressed, negative pressure suction is generated and transmitted to the surface absorption holes of the absorption block 4067 through the internal through-holes of the collection film 4066. When the laser emission power is increased, the laser will generate a large amount of heat on the surface of the hydraulic valve seat. To avoid overheating of the surface of the hydraulic valve seat, the heat generated by the laser marking can be absorbed into the inside of the collection film 4066 through the absorption block 4067.

[0024] Example 2: The difference from Example 1: Figure 4-Figure 6 The marking mechanism 5 includes a conveying box 501, the bottom of the conveying box 501 is slidably connected to the inner wall of the sliding groove 2 through a slider, the surface of the conveying box 501 is fixedly connected to a telescopic rod 503, the surface of the telescopic rod 503 is slidably connected to a laser emitter 502, and the end of the laser emitter 502 away from the conveying box 501 is fixedly connected to a launch tube 504, and expansion mechanisms 6 are provided on both sides of the laser emitter 502.

[0025] The marking mechanism 5 also includes a side plate 505, which is fixedly connected to both sides of the launch tube 504. The end of the side plate 505 away from the launch tube 504 is fixedly connected to a compression rod 506. Both sides of the launch tube 504 are fixedly connected to a covering block 507. The bottom of the inner wall of the covering block 507 is fixedly connected to an extrusion rod 508. The inner wall of the covering block 507 is provided with a compression component 509.

[0026] The compression assembly 509 includes a limit block 5091, the left side of the limit block 5091 is slidably connected to the two sides of the inner wall of the covering block 507 through a slider, the end of the extrusion rod 508 away from the bottom of the inner wall of the covering block 507 is fixedly connected to the surface of the limit block 5091, the inner wall of the limit block 5091 is fixedly connected to an absorption capsule 5094, and the surface of the limit block 5091 is fixedly connected to a connecting wheel 5093.

[0027] The compression assembly 509 also includes a guide block 5092, which is fixedly connected to both sides of the inner wall of the limit block 5091. The slots on both sides of the limit block 5091 are rotatably connected to the cover plate 5095 through a rotating shaft. The bottom of the limit block 5091 is slidably connected to the compression block, and a shrinkage bag is installed at the connection between the compression block and the limit block 5091. When pressed by the compression block, gas is generated to push the push rope 5096. The push rope 5096 is slidably connected to both sides of the limit block 5091, and the push rope 5096 is fixedly connected to the surface of the cover plate 5095 at one end of the push rope 5096 away from the limit block 5091.

[0028] The working method of the second embodiment is as follows: the propeller inside the working plate 1 is activated to drive the conveying box 501 to slide on the inner wall of the sliding groove 2. When the conveying box 501 slides to the surface of the hydraulic valve seat, the telescopic device inside the conveying box 501 is activated to drive the laser emitter 502 to slide on the surface of the telescopic rod 503. The laser emitter 502 is remotely activated to emit laser light from the emission tube 504, thereby printing a mark on the surface of the hydraulic valve seat. When a deeper mark is required on the surface of the hydraulic valve seat, the emission power of the laser emitter 502 is increased. In order to prevent the laser wave energy emitted from the emission tube 504 from being too high and thus leaving unnecessary marking marks on the surface of the hydraulic valve seat, the telescopic device inside the covering block 507 is activated to drive the limit block 5091 to slide downward. When the limit blocks 5091 on both sides move together, a portion of the laser wave energy emitted from the emission tube 504 will be guided into the absorption groove on the inner wall of the limit block 5091 through the multiple guide blocks 5092. This portion of the laser wave energy will be absorbed after entering the absorption groove. The capsule 5094 absorbs, and when the laser emitter 502 slides on the surface of the telescopic rod 503 to mark the surface of the hydraulic valve seat, the connecting wheel 5093 can slide on the surface of the valve seat, thereby facilitating the launch tube 504 to mark the surface of the valve seat. When the compression blocks at the bottom of the limit blocks 5091 on both sides squeeze each other, the compression blocks will shrink inward into the inner wall of the limit block 5091, and the contraction bag inside the limit block 5091 will generate air pressure after being squeezed by the outside and push the push rope 5096, thereby The push rope 5096 is extended and retracted outward from both sides of the limit block 5091 and pushes the cover plate 5095, so that one end of the cover plate 5095 rotates outward from the slots on both sides of the limit block 5091. When the laser marks the surface of the valve seat, the smoke generated by the evaporation of the material on the surface of the valve seat will be discharged outward from the exhaust holes on both sides of the limit block 5091, which can compress and limit the laser after the enhanced emission power to prevent the ejected laser wave energy from being too strong and causing overheating on the surface of the valve seat and producing unnecessary marking marks.

[0029] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8 The expansion mechanism 6 includes a plate 601, which is fixedly connected to both sides of the laser emitter 502. The end of the compression rod 506 away from the side plate 505 is fixedly connected to the spray chamber 603. The slots on both sides of the spray chamber 603 are slidably connected with flow belts 604. The end of the flow belt 604 away from the spray chamber 603 is fixedly connected to the movable tube 602. The flow belt 604 has a telescopic characteristic and an air groove is opened inside. When absorbing gas, it will expand and contract outward and push the movable tube 602. The movable tube 602 is slidably connected to the inner wall of the plate 601. One end of the movable tube 602 is fixedly connected to the suction tank 605. The end of the movable tube 602 away from the suction tank 605 is provided with a suction component 606.

[0030] The suction component 606 includes an expansion plate 6065, which is fixedly connected to one end of the movable tube 602. The top of the expansion plate 6065 is fixedly connected to an absorption film 6061, and the right side of the expansion plate 6065 is fixedly connected to a tightening tube 6062. The tightening tube 6062 is made of soft rubber material and has a compression chamber inside. When pressed from the outside, the space will shrink inward and form a pressure difference with the outside, thereby generating suction and transmitting it into the absorption film 6061. The end of the tightening tube 6062 away from the expansion plate 6065 is fixedly connected to the fixed plate 6063, and both sides of the absorption film 6061 are fixedly connected to the air collection ring 6064. The end of the air collection ring 6064 away from the absorption film 6061 is fixedly connected to the inner wall of the fixed plate 6063.

[0031] The working method of the third embodiment is as follows: when one end of the extrusion rod 508 is subjected to the downward sliding of the limit block 5091 and the extrusion rod 508 is compressed, the extrusion rod 508 will be expanded and contracted inwardly and generate gas to flow into the compression rod 506 through the internal gas groove of the side plate 505, and then the gas is introduced into the interior of the injection cavity 603 through the compression rod 506. The gas will push the flow belt 604 inside the injection cavity 603, so that the flow belts 604 on both sides expand and contract from the inside of the injection cavity 603 to the outside and push the movable tube 602, so that the movable tubes 602 on both sides slide on the inner wall of the sticking plate 601. When the movable tubes 602 on both sides slide outward by one end, when the laser emitted by the laser emitter 502 marks the surface of the valve seat, the air collecting ring 6 064 will be squeezed with the surface of the valve seat, thereby generating pressure on the shrinkage tube 6062, thereby driving the shrinkage tube 6062 to expand and contract inward. When the shrinkage tube 6062 expands and contracts inward, negative pressure suction will be generated and the smoke generated by the laser marking will be absorbed into the interior through the absorption film 6061. The smoke enters the interior of the movable tube 602 through the absorption film 6061, and the smoke in the movable tube 602 is absorbed into the interior through the suction tank 605. The smoke discharged through the exhaust holes on both sides of the limit block 5091 will be guided to the surface of the absorption film 6061 through the covering plate 5095, which can protect the large amount of smoke generated by the laser with increased emission power during marking, prevent the smoke from diffusing outward and affecting the operator, and can also quickly absorb the smoke.
