Specific embodiments

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Such as Figures 1 to 5As shown in the figure, the frame pressing and laser marking integrated machine according to the embodiment of the present utility model includes a pressing machine 1; a fixed frame 10 is fixedly connected to the side wall of the pressing machine 1; a first linear motor 11 is fixedly connected to the top of the fixed frame 10; a second linear motor 12 is installed in the middle of the first linear motor 11; a third linear motor 13 is installed in the middle of the second linear motor 12; a laser head 14 is installed on the top of the pressing machine 1; a first fixing plate 15 is fixedly connected to the side wall of the third linear motor 13; a laser rangefinder 16 is fixedly connected to the end of the first fixing plate 15; a focusing device 17 is fixedly connected to the side wall of the laser rangefinder 16; during operation, the frame is fixed at the bottom position of the laser head 14, the pressing machine 1 is started to press the frame, the first linear motor 11, the second linear motor 12 and the third linear motor 13 are controlled to move, so that the laser rangefinder 16 can move flexibly on one side of the pressing machine 1 and measure at different positions. The laser beam emitted by the laser rangefinder 16 irradiates a specific position of the frame, and part of the laser is reflected back for distance calculation. At the same time, the sensor in the focusing device 17 will emit a laser beam to the surface of the frame and receive the reflected light, so that the focusing device 17 calculates the distance from the laser head 14 to the surface of the frame and monitors the change of the frame position in real time. Then, the laser head 14 is used to perform laser marking on the frame. Through the second linear motor 12 and the third linear motor 13, precise control and positioning of the position of the laser rangefinder 16 can be achieved, the position of the laser rangefinder 16 can be quickly and accurately changed, effectively adapting to different frame sizes and shapes, enabling the laser rangefinder 16 to reach different angles and orientations, thereby obtaining comprehensive and accurate distance information, and enabling the laser beam to be accurately focused on a specific position of the frame through the focusing device 17, reducing the problems of marking errors or blurring, enabling the focusing state to be consistent during each marking, achieving a stable marking effect, reducing the adjustment time and marking errors, and effectively improving the production efficiency of frame laser marking.

[0028] As Figures 1 to 7As shown, a second fixing plate 2 is fixedly connected to the side wall of the first fixing plate 15; the second fixing plate 2 is fixedly connected to the side away from the focusing device 17; a dust suction pipe 21 is fixedly connected to the middle of the second fixing plate 2; the end of the dust suction pipe 21 penetrates through the middle of the second fixing plate 2; a dust suction hood 22 is fixedly connected to the end of the dust suction pipe 21; during operation, the end of the dust suction pipe 21 is connected to an air suction pump. When the vehicle frame is being engraved at the bottom of the laser head 14, the dust generated during the engraving process is sucked in through the dust suction hood 22. The dust enters the interior of the dust suction pipe 21 through the dust suction hood 22 for collection. By centrally sucking the dust through the dust suction hood 22, it can effectively reduce the dispersion of the dust generated during the laser engraving of the vehicle frame in the working environment, effectively reduce the adhesion of the dust to the surface of the equipment, effectively reduce the problem of surface corrosion and damage caused by long-term dust accumulation on the surface of the equipment, reduce the difficulty of cleaning caused by long-term adhesion of the dust to the surface of the equipment, and can effectively reduce the inhalation of the dust by the human body and the resulting health hazards.

[0029] As Figure 5 shown, two fixing rods 3 are fixedly connected to the side wall of the first fixing plate 15; the two fixing rods 3 are fixedly connected to the position near the top of the first fixing plate 15; the two fixing rods 3 are arranged oppositely; a sliding block 31 is slidably connected to the middle of the fixing rod 3; a glass plate 32 is fixedly connected to the middle of the two sliding blocks 31; during operation, the glass plate 32 is slid through the two sliding blocks 31 in the middle of the fixing rod 3 to move the glass plate 32 to a specified distance from the first fixing plate 15. When the vehicle frame is being laser engraved, the sparks and debris generated during the laser engraving process are blocked by the glass plate 32. The glass plate 32 can effectively block the sparks and debris generated during the laser engraving process, effectively reduce the splashing of the sparks and debris onto the surface of the laser rangefinder 16, can reduce the contact between the sparks and debris and the precision components in the laser rangefinder 16, and effectively reduce the damage to the precision components in the laser rangefinder 16. The high-quality glass plate 32 has a high transmittance, which can keep the purity and stability of the laser beam during transmission, reduce the reflection and refraction of the laser beam, and thus improve the measurement accuracy of the laser rangefinder 16.

[0030] As Figure 7 and Figure 8As shown, a filter cover 4 is installed in the middle of the dust suction pipe 21; two groups of elastic rods 41 are fixedly connected to the end of the filter cover 4; the two groups of elastic rods 41 are fixedly connected to both ends of the filter cover 4; every two of the elastic rods 41 form a group; the two elastic rods 41 are arranged oppositely; the elastic rods 41 are arc-shaped; a rubber block 42 is fixedly connected to the end of the elastic rod 41; during operation, the filter cover 4 is inserted into the inside from one end of the dust suction pipe 21. At the same time, the two groups of elastic rods 41 are in contact with the inner wall of the dust suction pipe 21. The two groups of elastic rods 41 are elastically bent under extrusion. The contact between the rubber block 42 and the inner wall of the dust suction pipe 21 increases the friction, so that the two groups of elastic rods 41 and the rubber block 42 are in close contact with the inner wall of the dust suction pipe 21, fixing the filter cover 4 inside the dust suction pipe 21. When the soot enters the middle of the dust suction pipe 21, the filter cover 4 filters out the particles and impurities in the soot. Through the filter cover 4, the particles and impurities contained in the soot generated during the laser engraving process can be effectively reduced, the particles and impurities can be effectively captured, the particles and impurities can be reduced from adhering to the inner wall of the dust suction pipe 21 when passing through the inside of the dust suction pipe 21, effectively reducing the accumulation of particles and impurities on the inner wall of the dust suction pipe 21, and effectively reducing the problems of scratches and damage caused by the accumulation of particles and impurities on the inner wall of the dust suction pipe 21.

[0031] As Figure 6 and Figure 7 shown, a corrugated pipe 5 is fixedly connected to the end of the dust suction hood 22; the corrugated pipe 5 is fixedly connected to the end away from the dust suction pipe 21; a lengthened hood 51 is fixedly connected to the end of the corrugated pipe 5; during operation, when the dust suction hood 22 sucks in the soot, the corrugated pipe 5 is pulled and stretched, so that the lengthened hood 51 moves to the laser engraving position, and one side of the corrugated pipe 5 is stretched to adjust the angle of the lengthened hood 51. Due to the good telescopic and deformation capabilities of the corrugated pipe 5, the lengthened hood 51 can effectively adjust the position and angle of the sucked-in soot, enabling the soot to be directly and effectively sucked into the inside of the dust suction hood 22, effectively reducing the diffusion and retention of the soot in the working environment, and effectively reducing the pollution caused by the dispersion of some un-sucked soot in the working environment, thereby effectively improving the efficiency of soot absorption.

[0032] As Figure 6 and Figure 7As shown, two support rods 6 are fixedly connected to the end of the dust suction hood 22; the two support rods 6 are fixedly connected inside the dust suction hood 22; the two support rods 6 are arranged oppositely; a plurality of elastic rods 61 are fixedly connected to the middle of the support rod 6; the plurality of elastic rods 61 are equidistantly distributed in the middle of the support rod 6; during operation, when the corrugated pipe 5 is stretched, the plurality of elastic rods 61 support at the bent part in the middle of the corrugated pipe 5. Since the support rod 6 is elastically arranged, when only one end of the corrugated pipe 5 is stretched to adjust the angle of the extension hood 51, the support rod 6 is elastically bent at the same time. The plurality of elastic rods 61 in the middle of the support rod 6 can effectively support and fix the corrugated pipe 5, effectively reducing the problems of shaking and swinging of the corrugated pipe 5 and the extension hood 51 due to wind force during the process of inhaling dust and smoke, effectively increasing the stability when the corrugated pipe 5 and the extension hood 51 inhale dust and smoke, and improving the accuracy and efficiency of dust and smoke cleaning.

[0033] During operation, the vehicle frame is fixed at the bottom position of the laser head 14. The press 1 is started to press the vehicle frame. The first linear motor 11, the second linear motor 12, and the third linear motor 13 are controlled to move, so that the laser rangefinder 16 can move flexibly on one side of the press 1 and perform measurements at different positions. The laser beam emitted by the laser rangefinder 16 irradiates a specific position of the vehicle frame, and part of the laser is reflected back for distance calculation. At the same time, the sensor in the focusing device 17 emits a laser beam to the surface of the vehicle frame and receives the reflected light, so that the focusing device 17 calculates the distance from the laser head 14 to the surface of the vehicle frame and monitors the change of the position of the vehicle frame in real time. Then, the laser head 14 performs laser marking on the vehicle frame. The end of the dust suction pipe 21 is connected to the suction pump. When the vehicle frame is being marked by the laser head 14 at the bottom, the dust generated during the marking process is sucked in through the dust suction hood 22. The dust passes through the dust suction hood 22 and enters the interior of the dust suction pipe 21 for collection. The glass plate 32 slides on the fixed rod 3 through two sliding blocks 31, so that the glass plate 32 moves to a specified distance from the first fixing plate 15. When the vehicle frame is being laser marked, the glass plate 32 blocks the sparks and debris during the laser marking process. The filter cover 4 is inserted into the interior from one end of the dust suction pipe 21. At the same time, the two groups of elastic rods 41 are in contact with the inner wall of the dust suction pipe 21. The two groups of elastic rods 41 are elastically bent under extrusion. The rubber block 42 contacts the inner wall of the dust suction pipe 21 to increase friction, so that the two groups of elastic rods 41 and the rubber block 42 are in close contact with the inner wall of the dust suction pipe 21, fixing the filter cover 4 inside the dust suction pipe 21. When the dust enters the middle of the dust suction pipe 21, the filter cover 4 filters the particles and impurities in the dust. When the dust suction hood 22 sucks in the dust, the bellows 5 is pulled and stretched, so that the extension hood 51 moves to the laser marking position. One side of the bellows 5 is stretched to adjust the angle of the extension hood 51. During the stretching process of the bellows 5, a plurality of elastic rods 61 support the bent part in the middle of the bellows 5. The support rod 6 is elastically arranged. When only one end of the bellows 5 is stretched to adjust the angle of the extension hood 51, the support rod 6 is elastically bent at the same time.
