Description

Technical Field

[0001] This invention belongs to the technical field of rotary joint laser marking fixtures, specifically relating to a convenient rotary shaft marking fixture based on intelligent manufacturing. Background Technology

[0002] Laser marking is a processing technology that uses a high-energy-density laser beam to permanently mark the surface of various materials. Its working principle involves either evaporating the surface material to expose the deeper layers, or using light energy to induce chemical and physical changes in the surface material to "etch" a mark, or burning away part of the material to reveal the desired pattern or text. Compared to traditional inkjet printing and mechanical engraving, laser marking offers significant advantages such as permanent marking, high precision, high speed, no consumables, and environmental friendliness. It has been widely used for product identification and traceability management in fields such as automotive parts, electronic products, medical devices, and hardware tools.

[0003] The announcement number is CN208496114U, describing a convenient rotary shaft marking fixture. It includes a stepper motor, a base, a transmission wheel assembly, a workpiece, driven rotary shafts, and a waste collection area. The stepper motor is mounted on the base. Two driven rotary shafts are mounted on the top of the base via an L-shaped mounting plate. The transmission wheel assembly is mounted on the side of the L-shaped mounting plate away from the driven rotary shafts. The transmission wheel assembly includes one driving wheel and two driven wheels. The driving wheel is connected to the output shaft of the stepper motor, and the driven wheels are connected to the transmission rotary shafts. The driven rotary shafts are located above the waste collection area, which is situated on one side of the base. The workpiece is placed on the two driven rotary shafts. During operation, this device encounters workpieces with different inner diameters, making it difficult for the rotary joint to connect them. This can lead to liquid leakage, reduced cooling of the workpiece, and scratches and welding defects on the inner end face of the workpiece, resulting in decreased sealing when the rotary joint connects to the workpiece's inner diameter.

All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-6 , Figure 11 As shown, a convenient rotary shaft marking fixture based on intelligent manufacturing includes a body 100, two sets of active rotary shafts 200 are mounted on the inner side of the body 100, a water pump 300 is mounted on the top of the body 100, and a telescopic water pipe 400 is mounted on the outer side of the water pump 300. An electric telescopic rod 101 is mounted on the top of the machine body 100. A movable plate 102 is mounted on the telescopic end of the electric telescopic rod 101. The movable plate 102 is slidably connected to the top of the machine body 100. Two sets of connecting rods 103 are fixedly connected to the outer side of the movable plate 102. A rotary joint 104 is slidably connected to the outer side of the two sets of connecting rods 103. The end of the rotary joint 104 near the active rotating shaft 200 is set with a conical structure. By setting the front end of the rotary joint 104 with a conical structure, when the rotary joint 104 moves toward the workpiece, it can fit against the end face of the inner hole of the workpiece, so that the rotary joint 104 can fit against the inner hole of the workpiece with a different inner hole diameter. The rotary joint 104 has an annular groove on the side near the moving plate 102. Two sets of connecting rods 103 are fixedly connected to annular sliding plates corresponding to the annular groove on their outer sides. The annular sliding plates are slidably connected to the inner side of the annular groove. By setting the connecting rods 103, the rotary joint 104 moves while the rotary joint 104 rotates. The connecting rods 103 remain connected to the rotary joint 104. The telescopic water pipe 400 is connected and rotatably connected to the inner side of the rotary joint 104. L-shaped support plates 105 are fixedly connected to both sides of the rotary joint 104. A clamping plate 10 is slidably connected to the inner side of the L-shaped support plate 105. 6. The two sets of clamping plates 106 have an arc-shaped structure on their facing side and near the active rotating shaft 200. A spring 107 is fixedly connected between the clamping plate 106 and the L-shaped support plate 105. Slots 108 are provided on both sides of the rotary joint 104. Two sets of extension plates 109 are fixedly connected to the inner side of the rotary joint 104 and the inner side of the slots 108. A rotating rod 110 is rotatably connected between the two sets of extension plates 109. A rotating plate 111 and a rotating plate 113 are fixedly connected to the outer side of the rotating rod 110. A grinding plate 112 is fixedly connected to the inner side of the rotating plate 111. By setting the grinding plate 112, the rotation... Before the adapter 104 is attached to the workpiece, the grinding plate 112 can grind the end face of the inner hole of the workpiece to reduce the roughness of the end face of the inner hole and improve the sealing of the attachment between the rotary adapter 104 and the inner hole of the workpiece. A spring 114 is fixedly connected between the rotating plate 111 and the rotary adapter 104. A groove 115 is provided on the outer side of the rotary adapter 104. A water outlet 116 and a water outlet 117 are respectively provided on the outer side of the rotary adapter 104 and inside the groove 115. A cavity is provided on the inner side of the rotary adapter 104. The cavity is connected to the telescopic water pipe 400 and the water outlet 116 and the water outlet 117 are connected.

[0021] In practical use, before laser marking, the workpiece is first placed above the two sets of active rotating shafts 200. The synchronous rotation of the two sets of active rotating shafts 200 causes the workpiece to rotate. Then, the electric telescopic rod 101 drives the moving plate 102 towards the workpiece, which in turn drives the two sets of connecting rods 103 towards the workpiece. The two sets of connecting rods 103 then drive the rotary joint 104 towards the workpiece, allowing the rotary joint 104 to fit against workpieces with different inner diameters. During the process of the adapter 104 engaging with the workpiece, the rotary adapter 104 drives the extension plate 109 to move, which in turn drives the rotating rod 110 to move. The rotating rod 110 then drives the rotating plate 111 to move, which in turn drives the grinding plate 112 to move. The spring 114 continuously presses against the rotating plate 111, allowing the grinding plate 112 to contact the end face of the workpiece's inner hole. Due to the workpiece's rotation, the grinding plate 112 can grind the end face of the workpiece's inner hole, thereby reducing... The roughness of the end face of the workpiece's inner hole is reduced, thereby improving the sealing performance when the rotary joint 104 is in contact with the workpiece's inner hole. When the rotary joint 104 is fully in contact with the workpiece's inner hole, the two sets of clamping plates 106 are pressed by the workpiece, causing the clamping plates 106 to move towards the spring 107, increasing the elastic potential energy of the spring 107. This allows the two sets of clamping plates 106 to clamp the workpiece and rotate with it. The rotation of the workpiece drives the rotary joint 104 to rotate as well, and the workpiece is then marked by a laser marking machine. After marking the workpiece, the water pump 300 is started, allowing water from the pump to enter the telescopic water pipe 400 and then into the rotary joint 104. Water can then be sprayed from the outlet 116 and outlet 117 on the outside of the rotary joint 104 into the inner hole of the workpiece to cool it down. When a set of workpieces is marked, the electric telescopic rod 101 moves the moving plate 102 away from the workpiece, causing the rotary joint 104 to stop its contact with the inner hole of the workpiece.

[0022] Example 2, as Figures 6-10As shown, based on Embodiment 1, a second groove 201 is provided on the outer side of the rotary joint 104. A pressure plate 202 is hinged to the inner side of the rotary joint 104 and inside the second groove 201. A hollow lifting plate 203 is slidably connected to the inner side of the rotary joint 104 and inside the second groove 201. A fixing plate 204 is fixedly connected to the inner side of the rotary joint 104 and inside the hollow lifting plate 203. A spring 205 is fixedly connected between the fixing plate 204 and the hollow lifting plate 203. A pressing block 206 is slidably connected to the bottom of the second groove 201 on the inner side of the rotary joint 104. By setting the pressing block 206, the pressing... When the pressure block 206 is pressed by the hollow lifting plate 203, the pressure block 206 can move towards the water pump 300. The curvature of the upper surface of the pressure plate 202 is the same as the curvature of the tapered structure at the front end of the rotary joint 104. The pressure plate 202 is in contact with the hollow lifting plate 203. Both the upper and lower ends of the hollow lifting plate 203 are set as arc structures. The hollow lifting plate 203 is in contact with the pressure block 206. One end of the pressure block 206 that is in contact with the hollow lifting plate 203 is set as a slope. A spring 207 is fixedly connected between the pressure block 206 and the rotary joint 104. A rectangular rod 208 is fixedly connected to the outside of the pressure block 206. The rectangular rod 208 slides... A rectangular rod 208 is connected to the inner side of the rotary joint 104. A shaped extrusion plate 209 is fixedly connected to the outer side of the rectangular rod 208 and located on the outer side of the rotary joint 104. An extrusion rod 210 is slidably connected to the inner side of the rotary joint 104 and inside the slot 108. By setting the extrusion rod 210, when the extrusion rod 210 extrudes the rotating plate 113, the grinding plate 112 can retract into the slot 108. This avoids the grinding plate 112 grinding the inner wall of the workpiece's inner hole, preventing unnecessary damage to the inner wall, and reduces the grinding time of the grinding plate 112, thus extending the grinding time of the grinding plate 112. To extend the service life, an installation plate 211 is fixedly connected to the top of the extrusion rod 210. A spring 212 is fixedly connected between the installation plate 211 and the rotary joint 104. The extrusion rod 210 passes through the rotary joint 104. Two sets of extension plates 213 are fixedly connected to the outside of the rotary joint 104. A rotating rod 214 is rotatably connected between the two sets of extension plates 213. A rocker plate 215 is fixedly connected to both sides of the rotating rod 214. The two ends of the rocker plate 215 are respectively attached to the irregular extrusion plate 209 and the extrusion rod 210. Both ends of the rocker plate 215 are set with an arc structure. The end of the extrusion rod 210 that is attached to the rocker plate 215 is set with an arc structure.

[0023] In practical use, when the grinding plate 112 finishes grinding the end face of the inner hole of the workpiece, as the grinding plate 112 moves deeper into the inner hole, the workpiece presses against the pressure plate 202, causing the pressure plate 202 to completely cover the opening of the second groove 201. When the pressure plate 202 completely covers the opening of the second groove 201, the pressure plate 202 presses against the hollow lifting plate 203, causing the hollow lifting plate 203 to move downwards, pressing against the extrusion block 206, causing the extrusion block 206 to move towards the moving plate 102, causing the extrusion block 206 to drive the rectangular rod 208 to move, causing the rectangular rod 208 to drive the irregularly shaped extrusion plate 209 to move, thus... The irregularly shaped extrusion plate 209 can extrude the rocker arm 215, allowing the rocker arm 215 to rotate around the rotating rod 214. This allows the rocker arm 215 to press against the extrusion rod 210, causing the extrusion rod 210 to move towards the rotating plate 113. The extrusion rod 210 then presses against the rotating plate 113, causing the rotating plate 113 to drive the rotating rod 110 to rotate. This causes the rotating rod 110 to drive the rotating plate 111 to retract into the slot 108. The rotating plate 111 then drives the grinding plate 112 to retract into the slot 108, preventing the grinding plate 112 from contacting the inner wall of the workpiece's inner hole, thus avoiding grinding the inner wall of the workpiece's inner hole. This avoids unnecessary damage to the inner wall of the workpiece's inner hole and reduces the grinding time of the grinding plate 112, thereby extending its service life. It also aims to allow the grinding plate 112 to be inserted into the slot 108 after the end face grinding is completed and before entering the inner hole. When a set of workpieces is marked and the rotary joint 104 stops contacting the workpiece, the workpiece stops pressing the pressure plate 202, causing the pressure plate 202 to stop pressing the hollow lifting plate 203. The hollow lifting plate 203 can then return to its original position due to the elastic force of the spring 205, allowing it to lift the pressure plate 202 and return it to its original position. When the hollow lifting plate 202... As the 3rd part returns to its original position, the hollow lifting plate 203 stops pressing the extrusion block 206, allowing the extrusion block 206 to return to its original position via the elastic force of the spring 207. This causes the irregular extrusion plate 209 to return to its original position, stops the extrusion of the rocker 215, and stops the extrusion of the extrusion rod 210. The extrusion rod 210 can then return to its original position via the tension of the spring 212, causing the extrusion rod 210 to press the rocker 215, thus returning the rocker 215 to its original position. As the extrusion rod 210 stops pressing the rotating plate 113, the rotating plate 111 can then return to its original position via the elastic force of the spring 114.

[0024] Example 3, as Figures 11-13As shown, based on Embodiment 1, a rotating rod 301 is rotatably connected to the inner side of the rotary joint 104 and the inner side of the groove 115. Multiple sets of rotating plates 302 are fixedly connected to the outer side of the rotating rod 301, and a pressing plate 303 is fixedly connected to the outer side of the rotating rod 301. All sets of rotating plates 302 are configured with an arc-shaped structure. The end of the pressing plate 303 away from the rotating rod 301 is also configured with an arc-shaped structure. A round rod 304 is rotatably connected to the inner side of the rotary joint 104 and below the groove 115. A water guide plate 305 is fixedly connected to the outer side of the round rod 304. By setting the water guide plate 305... 05, allowing the water guide plate 305 to swing left and right, guiding the water and constantly changing the water spray angle, increasing the contact area between the water and the inner wall of the workpiece's inner hole, thereby improving the cooling efficiency of the water on the workpiece. A rectangular plate 307 is fixedly connected to the inner side of the rotary joint 104 and below the groove 115. A spring 306 is fixedly connected between the rectangular plate 307 and the water guide plate 305. A push rod 308 is slidably connected to the inner side of the rotary joint 104 and below the groove 115. A triangular rod 309 is fixedly connected above the push rod 308.

[0025] In practical use, when water is sprayed into the inner hole of the workpiece from outlet 116 and outlet 117, the water sprayed from outlet 116 comes into contact with multiple sets of rotating plates 302, causing the rotating plates 302 to drive the rotating rod 301 to rotate. The rotating rod 301 then drives the pressing plate 303 to rotate around the rotating rod 301, allowing the pressing plate 303 to continuously press the triangular rod 309. This causes the triangular rod 309 to move towards the guide plate 305, thus... 9 drives the push rod 308 to move the guide plate 305 and squeeze the guide plate 305, causing the guide plate 305 to tilt to the right. When the squeezing plate 303 temporarily stops squeezing the triangular rod 309, the push rod 308 ends the squeezing of the guide plate 305, so that the guide plate 305 can tilt back to the left by the elastic force of the spring 306, thereby achieving the purpose of the guide plate 305 continuously tilting left and right to guide the direction of water spray, thereby improving the cooling efficiency of water on the workpiece.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
