Description

Technical Field

[0001] This utility model relates to the field of casting surface treatment application technology, and in particular to a laser cleaning machine for oxide scale on casting surfaces. Background Technology

[0002] In the casting industry, an oxide scale usually forms on the surface of castings. This oxide scale not only affects the appearance quality of the castings, but also has an adverse effect on subsequent processing and performance, such as reducing the adhesion of the coating and increasing the difficulty of machining.

[0003] Currently, mechanical grinding can easily damage the surface of castings, affecting their dimensional accuracy and surface quality; while chemical pickling generates a large amount of wastewater and waste gas, causing environmental pollution. Furthermore, the chemical reagents used in the pickling process are expensive and pose safety hazards.

[0004] However, existing laser cleaning machines for oxide scale on casting surfaces have certain shortcomings in their structural design, such as the difficulty in adjusting the relative position of the laser emitting device and the casting, making it difficult to adapt to castings of different sizes and shapes. Therefore, this utility model proposes a laser cleaning machine for oxide scale on casting surfaces. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a laser cleaning machine for oxide scale on the surface of castings, so as to solve the problem that the relative position between the laser emitting device and the casting is not easy to adjust in the prior art, so as to achieve efficient and precise cleaning of oxide scale on the surface of castings of different sizes and shapes, while improving the environmental performance of the equipment.

[0006] To solve the above technical problems, the present invention provides a laser cleaning machine for oxide scale on the surface of castings, including a working plate, wherein a positioning toothed ring is bolted to the top of the working plate near the outer arc wall, and a positioning component is bolted to the center of the top of the working plate.

[0007] The inner wall of the positioning toothed ring is engaged with a laser cleaning mechanism, which moves in a circular motion around the positioning component on the positioning toothed ring to laser clean the oxide scale on the surface of the casting.

[0008] The present invention is further configured such that: the laser cleaning mechanism includes a moving mechanism, the moving mechanism includes a moving plate slidably connected to the outer arc wall of the positioning tooth ring, the top of the moving plate is bolted to a moving motor, the output end face of the moving motor is fixedly connected to a drive gear, and the outer wall of the drive gear is meshed with the inner wall of the positioning tooth ring.

[0009] By using the above technical solution, the moving motor is started, and its drive shaft drives the drive gear on the end face to rotate, thereby meshing with it on the inner wall of the positioning gear ring, so that the moving plate makes circumferential motion on the positioning gear ring, thus achieving the cleaning of the circumferential surface.

[0010] The present invention is further configured such that: the movable plate is L-shaped and the inner side wall is rotatably connected to a roller, and the roller is rotatably connected to a limiting groove opened on the outer arc wall of the positioning tooth ring.

[0011] The above technical solution enables the moving plate to roll on the inner wall of the limiting groove using rollers when it is making circular motion, thereby ensuring the stability of the circular motion.

[0012] The present invention is further configured such that: the laser cleaning mechanism also includes an adjustment mechanism installed on the top of the movable plate; the adjustment mechanism includes a mounting frame, the mounting frame is U-shaped, an adjustment motor is bolted to the top of the mounting frame, a lead screw is fixedly connected to the output shaft end face of the adjustment motor, an adjustment plate is threaded to the outer wall of the lead screw, a laser generator is bolted to the middle of the side wall of the adjustment plate, and sliding rods are symmetrically fixedly connected to both sides of the lead screw inside the mounting frame.

[0013] By using the above technical solution, the adjustment motor is started, and its drive shaft drives the lead screw on the end face to rotate, thereby causing the adjustment plate connected to the outer wall thread to slide on the slide rod, which in turn allows the laser generator on one side to be vertically adjusted, thus facilitating the cleaning of the casting surface at different heights.

[0014] The present invention is further configured such that the adjusting plate is slidably connected to two sliding rods near its two ends.

[0015] The above technical solution facilitates stable sliding of the adjustment plate under the action of the slide rod when adjusting it.

[0017] Through the above technical solution, the rotation of the eccentric adjusting block is used to press it against the limiting block fixed on the guide rod by the locking bolt on one side, thereby driving the extrusion block to slide on the guide rod. Then, the protective block B is used to extrude the placed casting, and the protective block A is used to achieve protective positioning and fixation.

[0018] The present invention is further configured such that: the limiting block is fixed to the outer wall of the guide rod by locking bolts provided on its side wall; a positioning rod is provided through the limiting block near the top position, and the positioning rod extends into the interior of the extrusion block for fixation; a stop block is fixedly connected to the end face of the positioning rod; a spring is provided wrapped around the outer wall of the positioning rod, and the end face of the spring abuts against the limiting block and the stop block respectively.

Furthermore, during disassembly, the spring's return elasticity allows the extrusion block to quickly reset.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figures 1-4 As shown, a laser cleaning machine for oxide scale on the surface of castings includes a working plate 1. A positioning toothed ring 2 is bolted to the top of the working plate 1 near the outer arc wall. A laser cleaning mechanism 3 is engaged with the inner wall of the positioning toothed ring 2. The laser cleaning mechanism 3 moves circumferentially around the positioning component 4 on the positioning toothed ring 2 to laser clean the oxide scale on the surface of the casting. The laser cleaning mechanism 3 includes a moving mechanism 31, which includes a moving plate 311 slidably connected to the outer arc wall of the positioning toothed ring 2. The moving plate 311 is L-shaped, and a roller 312 is rotatably connected to its inner side wall. The roller 312 is rolled in a limiting groove 21 opened on the outer arc wall of the positioning toothed ring 2. To facilitate the circular motion of the movable plate 311, it can roll on the inner wall of the limiting groove 21 using the roller 312, thereby ensuring the stability of the circular motion. The top of the movable plate 311 is bolted to a movable motor 313, and the output end face of the movable motor 313 is fixedly connected to a drive gear 314. The outer wall of the drive gear 314 is meshed with the inner wall of the positioning gear ring 2. When the movable motor 313 is started, its drive shaft drives the drive gear 314 on the end face to rotate, thereby meshing with the inner wall of the positioning gear ring 2, so that the movable plate 311 can make circular motion on the positioning gear ring 2 to achieve the cleaning of the circumferential surface.

[0031] The laser cleaning mechanism 3 also includes an adjustment mechanism 32 mounted on the top of the movable plate 311. The adjustment mechanism 32 includes a mounting frame 321, which is U-shaped. An adjustment motor 322 is bolted to the top of the mounting frame 321. A lead screw 323 is fixedly connected to the output shaft end face of the adjustment motor 322. An adjustment plate 324 is threadedly connected to the outer wall of the lead screw 323. The adjustment plate 324 is slidably connected to two slide rods 326 near both ends, so that it can slide stably under the action of the slide rods 326 when the adjustment plate 324 is adjusted. A laser generator 325 is bolted to the middle of the side wall of the adjustment plate 324. Slide rods 326 are symmetrically fixedly connected to both sides of the lead screw 323 inside the mounting frame 321. When the adjustment motor 322 is started, its drive shaft drives the lead screw 323 at the end face to rotate, so that the adjustment plate 324 threaded to the outer wall slides on the slide rods 326, thereby allowing the laser generator 325 on one side to be vertically adjusted, thus facilitating the cleaning of casting surfaces of different heights.

[0032] like Figure 5 As shown, a positioning assembly 4 is bolted to the top center of the work plate 1. The positioning assembly 4 includes a fixed seat 41 mounted on the work plate 1. A positioning frame 42 is bolted to the top of the fixed seat 41 near one end. A protective block A43 is bolted to the side wall of the positioning frame 42. A guide rod 44 is installed in the middle of the inner wall of the fixed seat 41 and extends into the interior of the positioning frame 42. A limit block 45 and a pressing block 46 are slidably connected to the outer wall of the guide rod 44. The limit block 45 is fixed to the outer wall of the guide rod 44 by a locking bolt 451 provided on its side wall. A positioning bolt is provided through the limit block 45 near the top. The positioning rod 452 extends into the interior of the extrusion block 46 and is fixed. A stop block 453 is fixedly connected to the end face of the positioning rod 452. A spring 454 is wrapped around the outer wall of the positioning rod 452, and the end face of the spring 454 abuts against the limiting block 45 and the stop block 453 respectively. This allows the spring 454 to slide on the guide rod 44 when the extrusion block 46 is being extruded and adjusted, thereby driving the positioning rod 452 to move. The stop block 453 on the end face is used to extrude the spring 454. Furthermore, when disassembling the extrusion block 46, the spring 454 can be used to quickly reset the extrusion block 46.

[0033] The side wall of the extrusion block 46 is bolted with a protective block B47. The top of the extrusion block 46 is rotatably connected with an eccentric adjustment block 461, which abuts against the side wall of the limiting block 45. By rotating the eccentric adjustment block 461, it abuts against the limiting block 45, which is fixed to the guide rod 44 on one side by a locking bolt 451. This causes the extrusion block 46 to slide on the guide rod 44. Then, the protective block B47 is used to extrude the placed casting, and the protective block A43 is used to achieve protective positioning and fixation.

[0034] In use, the casting to be processed is first placed into the positioning assembly 4. The rotation of the eccentric adjusting block 461 causes it to press against the limiting block 45, which is fixed to the guide rod 44 by the locking bolt 451. This causes the pressing block 46 to slide on the guide rod 44. Then, the protective block B47 presses the placed casting, and the protective block A43 provides protective positioning and fixation. Next, the laser generator 325 in the initial position is activated to clean the surface of the casting, and simultaneously, the moving motor 313 is started, its drive shaft driving the end face... The drive gear 314 rotates, causing it to mesh with the inner wall of the positioning gear ring 2. This causes the moving plate 311 to move in a circular motion on the positioning gear ring 2, achieving circumferential cleaning. After cleaning one revolution, the adjusting motor 322 is started, and its drive shaft drives the lead screw 323 on the end face to rotate. This causes the adjusting plate 324, which is threaded on the outer wall, to slide on the slide rod 326, thereby allowing the laser generator 325 on one side to be vertically adjusted. This, together with the moving mechanism 31, achieves another circumferential cleaning operation until the entire cleaning operation is completed.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
