Description

Technical Field

[0001] This utility model relates to the field of high-pressure washer nozzle processing technology, specifically to a coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles. Background Technology

[0002] The nozzle of a high-pressure washer is a key component of high-pressure water jet cleaning equipment. It uses high-pressure water to form a jet to peel and wash away dirt. The nozzle's internal aperture design enables water flow focusing. When high-pressure water passes through, the change in aperture alters the water flow velocity and pressure distribution, creating a high-speed jet that impacts the target surface. To ensure precise control of jet pressure and flow, micro-aperture laser processing is used to guarantee the precision of the nozzle aperture.

[0003] According to the coaxial dual-vision control device for dual-beam laser processing disclosed in Chinese Patent CN223114373U, a welding frame and a laser beam generator are included. A cantilever beam near the top is slidably connected within the welding frame. A rotating shaft is located at the bottom of the cantilever beam, and a horizontal plate is fixedly connected to the bottom of the rotating shaft. A lead screw is rotatably connected to the bottom of the horizontal plate. In this invention, a horizontal plate is provided, and below the horizontal plate are two threaded sleeves, a first threaded sleeve and a second threaded sleeve, whose spacing is controlled by the lead screw. Both threaded sleeves have adapters at their bottoms for mounting the laser beam generators. Therefore, compared to existing technologies, this device has two laser beam generator spacing adjustment functions, making it suitable for laser welding at two welding positions with different spacings, thus increasing the applicability of dual-beam welding.

[0004] The aforementioned device only allows for adjustment of the dual laser spacing and switching of processing points via rotation during processing, but lacks independent X / Y axis translation adjustment, resulting in limited adjustment dimensions. Therefore, we provide a coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles. Utility Model Content

[0005] The purpose of this invention is to provide a coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles, in order to solve the problems mentioned in the background art.

[0007] Preferably, the adjusting part includes a fixed plate fixedly connected to the top left side of the frame, a telescopic rod one fixedly connected to the back of the fixed plate, a movable plate fixedly connected to the rear end of the telescopic rod one, a horizontal adjusting rod fixedly connected to the top right side of the movable plate, the side end of the horizontal adjusting rod being slidably connected to the inner surface of the adjusting groove, the adjusting groove being opened on the top side of the frame, a telescopic rod two fixedly connected to the bottom right side of the movable plate, an adjusting block fixedly connected to the right end of the telescopic rod two, a vertical adjusting rod fixedly connected to the bottom of the adjusting block, and the inner surface of the adjusting block being sleeved on the outer wall of the horizontal adjusting rod.

[0008] Preferably, the drilling section includes a telescopic rod three fixedly connected to the top of the adjusting block. A stabilizing plate is fixedly connected to the top of the telescopic rod three, and a stabilizing rod is fixedly connected to the bottom of the stabilizing plate. The bottom end of the stabilizing rod passes through the top of the vertical adjusting rod and is fixedly connected to a fixing frame. A rotary motor is fixedly connected to the inner surface of the fixing frame. A U-shaped plate is fixedly connected to the output end of the rotary motor. A motor is fixedly connected to the back of the U-shaped plate. A bidirectional lead screw is fixedly connected to the output end of the motor. A sliding block is threaded onto the outer wall of the bidirectional lead screw. A laser generator is fixedly connected to the bottom of the sliding block. The middle end of the reciprocating lead screw is rotatably connected to the inner top of the U-shaped plate through a bearing bracket. An extension frame is fixedly connected to the left side of the fixing frame, and a camera is fixedly connected to the bottom right side of the extension frame.

[0009] Preferably, the top surfaces of the front and rear ends of the vertical adjustment rod are in contact with and slidably connected to the top and bottom surfaces of the frame, providing support and guidance for the adjustment block.

[0010] Preferably, the inner surface of the adjusting block and the outer wall of the horizontal adjusting rod are configured to slide together, ensuring that the adjusting block moves only left and right along the horizontal adjusting rod, thereby achieving linear precision adjustment of the laser generator in the left and right directions.

[0011] Preferably, the bottom end of the stabilizing rod and the top end of the vertical adjusting rod are connected by a movable through-hole, so that the bottom end of the stabilizing rod can slide up and down along the top end of the vertical adjusting rod, thereby guiding the fixing frame and the laser generator to rise and fall smoothly in the vertical direction.

[0012] Preferably, the number of laser generators is set to two, and the two laser generators are respectively fixedly connected to the bottom of two sliding blocks. The nozzle can be symmetrically or parallelly processed by the dual laser generators.

[0013] Compared with the prior art, this utility model provides a coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles, which has the following beneficial effects: 1. The coaxial vision alignment fixture for laser processing of micro-holes in the nozzles of this high-pressure washer involves activating the first telescopic rod to move the movable plate back and forth along the frame. The movable plate then moves the horizontal adjusting rod synchronously along the adjusting groove until the movable plate reaches the target position. Activating the second telescopic rod then pushes the adjusting block to slide along the horizontal adjusting rod. At this time, the vertical adjusting rod moves left and right along the horizontal adjusting rod along with the adjusting block. Simultaneously, the top surfaces of the front and rear ends of the vertical adjusting rod slide smoothly along the bottom surface of the frame, providing support and guidance for the adjusting block, until the laser generator moves to the target horizontal position. This allows for the processing of nozzles of different sizes and micro-hole positions.

[0014] 2. The coaxial vision alignment fixture for laser processing of micro-holes in the nozzle of this high-pressure washer uses a telescopic rod. Activating the telescopic rod causes the piston rod to extend and retract, moving the stabilizing plate, stabilizing rod, and fixing frame up and down until the distance between the laser generator focus and the nozzle surface meets the processing requirements. Then, the rotary motor is activated, driving the U-shaped plate to rotate to a set angle, aligning the laser generator axis with the nozzle micro-hole angle. The motor then drives the bidirectional lead screw to rotate, causing two sliding blocks to move in opposite directions along the lead screw. This adjusts the distance between the two laser generators according to processing needs. A camera maintains relative position synchronization with the laser generators, capturing real-time images of the processing area and feeding them back to an external terminal. Operators can visually confirm the alignment of the laser focus with the micro-hole markings, avoiding deviations caused by manual visual inspection. Attached Figure Description

[0019] Example 1: The coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles provided by this utility model, such as... Figures 1 to 4 As shown: Coaxial vision alignment fixture for laser processing of micro-holes in high-pressure cleaner nozzles, including: processing table 1; Positioning seat 2 is fixedly connected to the top of the processing table 1; Frame 3 is fixedly connected to the top of the processing table 1; And a processing assembly 4 fixedly connected to the processing table 1 and the frame 3 support; the processing assembly 4 includes an adjustment part 41 fixedly connected to the surface of the frame 3, and the adjustment part 41 is connected to a punching part 42.

[0020] The adjustment part 41 includes a fixed plate 411 fixedly connected to the top left side of the frame 3. A telescopic rod 412 is fixedly connected to the back of the fixed plate 411. A movable plate 413 is fixedly connected to the rear end of the telescopic rod 412. A horizontal adjustment rod 414 is fixedly connected to the top right side of the movable plate 413. The side end of the horizontal adjustment rod 414 is slidably connected to the inner surface of the adjustment groove 415, which is located on the top side of the frame 3. A telescopic rod 416 is fixedly connected to the bottom right side of the movable plate 413. An adjustment block 417 is fixedly connected to the right end of the telescopic rod 416. A vertical adjustment rod 418 is fixedly connected to the bottom of the adjustment block 417. The inner surface of the adjustment block 417 is fitted onto the outer wall of the horizontal adjustment rod 414.

[0021] In this embodiment, the top surfaces of the front and rear ends of the vertical adjustment rod 418 are in contact with and slidably connected to the top and bottom surfaces of the frame 3, providing support and guidance for the adjustment block 417.

[0022] Furthermore, the inner surface of the adjusting block 417 and the outer wall of the transverse adjusting rod 414 are configured to slide together, ensuring that the adjusting block 417 moves only left and right along the transverse adjusting rod 414, thereby achieving linear precision adjustment of the laser generator 4210 in the left and right directions.

[0023] Example 2: Based on Example 1, the coaxial vision alignment fixture for laser processing of micro-holes in high-pressure washer nozzles provided by this utility model, such as... Figures 1 to 4 As shown: The drilling section 42 includes a telescopic rod 421 fixedly connected to the top of the adjusting block 417. A stabilizing plate 422 is fixedly connected to the top of the telescopic rod 421, and a stabilizing rod 423 is fixedly connected to the bottom of the stabilizing plate 422. The bottom end of the stabilizing rod 423 passes through the top of the vertical adjusting rod 418 and is fixedly connected to a fixing frame 424. A rotary motor 425 is fixedly connected to the inner surface of the fixing frame 424, and a U-shaped plate 426 is fixedly connected to the output end of the rotary motor 425. A motor 427 is fixedly connected to the back of 426. A bidirectional lead screw 428 is fixedly connected to the output end of the motor 427. A sliding block 429 is threadedly connected to the outer wall of the bidirectional lead screw 428. A laser generator 4210 is fixedly connected to the bottom of the sliding block 429. The middle end of the reciprocating lead screw 428 is rotatably connected to the inner top of the U-shaped plate 426 through a bearing bracket. An extension frame 4211 is fixedly connected to the left side of the fixed frame 424. A camera 4212 is fixedly connected to the bottom right side of the extension frame 4211.

[0024] In this embodiment, the bottom end of the stabilizing rod 423 and the top end of the vertical adjusting rod 418 are configured to be movable through each other. By sliding the bottom end of the stabilizing rod 423 up and down along the top end of the vertical adjusting rod 418, the fixing frame 424 and the laser generator 4210 can be guided to rise and fall smoothly in the vertical direction.

[0025] Furthermore, the number of laser generators 4210 is set to two, and the two laser generators 4210 are fixedly connected to the bottom of the two sliding blocks 429 respectively. The dual laser generators 4210 can simultaneously perform symmetrical or parallel micro-hole processing on the nozzle.

[0026] In actual operation, when this device is used, the high-pressure washer nozzle workpiece is fixed on the positioning seat 2 by the clamp. The telescopic rod 412 is activated to drive the movable plate 413 to move along the front and back direction of the frame 3. The movable plate 413 drives the horizontal adjusting rod 414 to slide synchronously along the adjusting groove 415 until the laser generator 4210 moves to the front and back position corresponding to the area to be processed by the nozzle. Then, the telescopic rod 416 is activated to push the adjusting block 417 to slide left and right along the outer wall of the horizontal adjusting rod 414. At the same time, the adjusting block 417 drives the vertical adjusting rod 418 to slide along the bottom surface of the frame 3, thereby driving the drilling part 41 to move left and right as a whole until the laser generator 4210 is aligned with the horizontal coordinate of the micro hole.

[0027] The telescopic rod 421 is activated, which drives the stabilizing rod 423 to move up and down through the stabilizing plate 422. The stabilizing rod 423 drives the fixing frame 424 to move up and down until the distance between the focal point of the laser generator 4210 and the surface of the nozzle reaches the processing requirements, so that the axis of the laser generator 4210 matches the processing point of the nozzle micro-hole. The motor 427 is activated to drive the bidirectional lead screw 428 to rotate, so that the two sliding blocks 429 slide in opposite directions along the bidirectional lead screw 428, thereby adjusting the distance between the two laser generators 4210 according to the processing needs.

[0028] The camera 4212 captures images of the processing area in real time. The focus of the laser generator 4210 is observed on the external screen to see if it is aligned with the micro-hole marking point. If there is a deviation, the above steps are repeated for fine adjustment. After confirming that the alignment is correct, the laser generator 4210 is started. The two laser generators 4210 emit lasers synchronously to complete the micro-hole processing.
