Description

Technical Field

[0001] This utility model relates to a polishing device for preparing high-temperature resistant nuts, belonging to the technical field of nut polishing devices. Background Technology

[0002] High-temperature nuts (made of nickel-based alloys, titanium alloys, or stainless steel) are widely used in high-temperature and high-pressure environments such as aerospace, automotive engines, and nuclear power equipment. Their surface quality directly affects the thread fit accuracy, fatigue resistance, and corrosion resistance; therefore, polishing is a crucial step in the manufacturing process.

[0003] For example, utility model patent CN221716556U discloses a polishing device for hexagonal nuts, including a base, a stand, an inclined platform, a gantry, a guide rail, an alignment mechanism, a support module, a locking mechanism, a turning mechanism, and a grinding mechanism. The upper left and right sides of the base are fixedly connected to the stand. An inclined platform with an angle of 120 degrees is fixedly connected to the opposite side of the upper end of the stand. A gantry is fixedly connected to the rear side of the upper end of the base. A guide rail passing under the gantry is installed on the upper end of the base. An alignment mechanism is installed at the rear end of the guide rail. The support module is a V-shaped structure adapted to the adjacent side plane of the hexagonal nut and is snapped onto the alignment mechanism. A longitudinally sliding locking mechanism is installed between the front ends of the stand. A turning mechanism is installed on the gantry. The hexagonal nut is placed on the support module and clamped and fixed between the locking mechanism and the turning mechanism. A grinding mechanism with an output unit facing the side plane of the hexagonal nut is installed on the inclined platform.

[0004] However, the above solution has the following shortcomings in practical use: The aforementioned device uses a V-shaped support module that is compatible with the hexagonal nut to stably lift and fix the nut. With the help of two obliquely opposite grinding mechanisms, it can grind and polish two different side planes of the hexagonal nut at one time, improving the polishing efficiency. However, the aforementioned patent can only grind the outer circumference of one nut at a time, and cannot grind a large number of nuts, thus reducing the overall processing efficiency of the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a polishing device for preparing high-temperature resistant nuts. Through the cooperation of the polishing mechanism (2) and the positioning mechanism (3), multiple nuts can be positioned at the same time. By simultaneously rotating multiple nuts around the fixed shaft (311) and rotating on their own axis, the outer periphery of multiple nuts can be polished efficiently.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A polishing device for preparing high-temperature resistant nuts includes a base, a mounting frame on one side of the base, a connecting rod fixedly connected between the mounting frame and the base, two through grooves through the surface of the mounting frame, and a polishing mechanism inside the mounting frame. The polishing mechanism is used to polish the outer periphery of the nut; A positioning mechanism is provided above the base, which is used to fix multiple nuts simultaneously and rotate them synchronously.

[0007] Preferably, the polishing mechanism includes a slide bar, a first stepper motor, and a driven transmission wheel. Two slide bars are provided, each fixedly connected to the top and bottom of the mounting frame. Sliding blocks are slidably disposed on the outer periphery of each slide bar, and each sliding block is slidably connected to two through slots. Tension springs are sleeved on the outer periphery of each slide bar, with one end of each tension spring abutting against the bent section of the two slide bars, and the other end of each tension spring abutting against the two sliding blocks. A tension wheel is rotatably disposed between the sliding blocks. The bottom of the first stepper motor is fixedly connected to the mounting frame. The output shaft of the first stepper motor is fixedly connected to the drive drive wheel. The drive drive wheel is rotatably connected to the mounting frame. The driven drive wheel is rotatably connected to the mounting frame. A polishing belt is sleeved between the tension wheel, the drive drive wheel, and the driven drive wheel. Starting the first stepper motor can drive the drive wheel to rotate. At the same time, the drive wheel will drive the polishing belt to rotate in a cycle around the drive wheel, the driven wheel and the tension wheel. When the polishing belt is deformed by pressure, the two tension springs can squeeze the two sliders respectively, and the two sliders will drive the tension wheel to tighten the polishing belt.

[0008] Preferably, the positioning mechanism includes a rotating structure and a positioning structure, wherein the rotating structure is used to drive multiple nuts to rotate synchronously, and the positioning structure is used to simultaneously fix and position the multiple nuts.

[0009] Preferably, the rotating structure includes a fixed shaft, the bottom of which is fixedly connected to the base, a connecting ring fixedly connected to the outer periphery of the fixed shaft, a fixed toothed ring fixedly connected to the outer periphery of the connecting ring, a first rotating disk rotatably connected to the top of the fixed shaft, and a driven toothed ring fixedly connected to the bottom of the first rotating disk. The first rotating disk has multiple rotating shafts that are rotatably connected to it. Each of the rotating shafts has a driven gear fixedly connected to its bottom end. Each of the driven gears meshes with a fixed gear ring. Each of the rotating shafts has a positioning ring fixedly connected to its outer circumference. A second stepper motor is fixedly connected to the top of the connecting ring, and a drive gear is fixedly connected to the output shaft of the second stepper motor. The drive gear meshes with the driven gear ring. Nuts can be fitted onto the top of multiple rotating shafts, and the bottom of each nut is positioned by a positioning ring. Then, starting the second stepper motor drives the driven gear ring and the first rotating disk to rotate via the drive gear. At the same time, the first rotating disk drives multiple rotating shafts to rotate synchronously. Since the driven gears at the bottom of multiple rotating shafts are meshed with the fixed gear ring, while the first rotating disk drives multiple rotating shafts to rotate around the fixed shaft, each rotating shaft is also driven to rotate by its own axis by the driven gears. In this way, while rotating around the fixed shaft, multiple nuts can sequentially contact the rotating polishing belt, and while in contact with the polishing belt, multiple nuts can rotate on their own axis, so that the outer circumference of multiple nuts can be polished by the polishing belt.

[0010] Preferably, the positioning structure includes a support frame, the bottom of which is fixedly connected to the base, an electric push rod is fixedly connected to the middle of the support frame, a mounting frame is fixedly connected to the output end of the electric push rod, and two guide rods are fixedly connected to the top of the mounting frame. Both guide rods pass through the support frame and are slidably connected to the support frame. The mounting bracket has a second rotating disk rotatably mounted at its bottom. Multiple mounting components are fixedly connected to the outer periphery of the bottom of the second rotating disk. Each of the multiple mounting components has a pressing component rotatably mounted on one side of its bottom, and a positioning component is fixedly connected to the other side of its bottom. A limiting rod is fixedly connected to the bottom center of the second rotating disk, and a limiting sleeve is sleeved on the bottom end of the limiting rod. The limiting sleeve is fixedly connected to the first rotating disk. In the initial state, when the nut is fitted onto the top of the rotating shaft, the positioning component on one side of the nut will limit the angle of the nut. After multiple nuts are fitted, the electric push rod can be activated to drive the second rotating disk to move downward. At the same time, the second rotating disk will synchronously drive the pressing and positioning components at the bottom of multiple mounting components to move downward. At this time, multiple pressing components will abut against the top of multiple nuts respectively, thereby limiting the multiple nuts. Multiple positioning components will separate from multiple nuts, thereby preventing the nuts from being limited and unable to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the cooperation of the polishing mechanism and the positioning mechanism, multiple nuts can be positioned at the same time, and by making multiple nuts rotate around the fixed axis and rotate on their own axis at the same time, the outer circumference of multiple nuts can be polished efficiently.

[0016] Please see Figure 1-7 This utility model provides a technical solution: A polishing device for preparing high-temperature resistant nuts includes a base 1, a mounting frame 11 on one side of the base 1, a connecting rod 12 fixedly connected between the mounting frame 11 and the base 1, two through slots 13 through the surface of the mounting frame 11, and a polishing mechanism 2 inside the mounting frame 11.

[0018] Furthermore, the positioning mechanism 3 includes a rotating structure 31 and a positioning structure 32. The rotating structure 31 is used to drive multiple nuts to rotate synchronously, and the positioning structure 32 is used to fix and position multiple nuts synchronously.

[0019] Furthermore, the rotating structure 31 includes a fixed shaft 311, the bottom of which is fixedly connected to the base 1, a connecting ring 312 is fixedly connected to the outer periphery of the fixed shaft 311, a fixed toothed ring 313 is fixedly connected to the outer periphery of the connecting ring 312, a first rotating disk 314 is rotatably connected to the top of the fixed shaft 311, and a driven toothed ring 315 is fixedly connected to the bottom of the first rotating disk 314. Multiple rotating shafts 316 are provided through the surface of the first rotating disk 314. All rotating shafts 316 are rotatably connected to the first rotating disk 314. A driven gear 317 is fixedly connected to the bottom end of each of the multiple rotating shafts 316. The multiple driven gears 317 are meshed with a fixed gear ring 313. A positioning ring 318 is fixedly connected to the outer periphery of each of the multiple rotating shafts 316. A second stepper motor 319 is fixedly connected to the top of the connecting ring 312. A drive gear 3110 is fixedly connected to the output shaft of the second stepper motor 319. The drive gear 3110 meshes with the driven gear ring 315.

[0020] Furthermore, the positioning structure 32 includes a support frame 321, the bottom of which is fixedly connected to the base 1, an electric push rod 322 is fixedly connected to the middle of the support frame 321, a mounting frame 323 is fixedly connected to the output end of the electric push rod 322, and two guide rods 324 are fixedly connected to the top of the mounting frame 323. Both guide rods 324 pass through the support frame 321 and are slidably connected to the support frame 321. The bottom of the mounting bracket 323 is rotatably provided with a second rotating disk 325. Multiple mounting parts 326 are fixedly connected to the outer periphery of the bottom of the second rotating disk 325. Each of the multiple mounting parts 326 has a pressing part 327 rotatably provided on one side of its bottom, and a positioning part 328 is fixedly connected to the other side of its bottom.

The limiting sleeve 3210 is fixedly connected to the first rotating disk 314.

[0021] The workflow of this embodiment is as follows: In the initial state, when the nut is fitted onto the top of the rotating shaft 316, the positioning part 328 on one side of the nut will limit the angle of the nut. After multiple nuts are fitted, by starting the electric push rod 322, the second rotating disk 325 can be driven to move downward. At the same time, the second rotating disk 325 will drive the pressing part 327 and positioning part 328 at the bottom of multiple mounting parts 326 to move downward. At this time, multiple pressing parts 327 will abut against the top of multiple nuts respectively, thereby limiting the multiple nuts. Multiple positioning parts 328 will separate from multiple nuts, thereby preventing the nuts from being limited and unable to rotate. Then, the second stepper motor 319 is started, which can drive the driven gear ring 315 and the first rotating disk 314 to rotate through the drive gear 3110. At the same time, the first rotating disk 314 will drive multiple rotating shafts 316 to rotate synchronously. Since the driven gears 317 at the bottom of the multiple rotating shafts 316 are meshed with the fixed gear ring 313, while the first rotating disk 314 drives the multiple rotating shafts 316 to rotate around the fixed shaft 311, the multiple rotating shafts 316 will also be driven to rotate by the multiple driven gears 317 respectively. In this way, while the multiple nuts are rotating around the fixed shaft 311, they can contact the rotating polishing belt 28 in sequence. While contacting the polishing belt 28, the multiple nuts can rotate by themselves, so that the outer circumference of the multiple nuts can be polished by the polishing belt 28. By starting the first stepper motor 22, the active drive wheel 27 can be driven to rotate. At the same time, the active drive wheel 27 will drive the polishing belt 28 to rotate cyclically around the active drive wheel 27, the driven drive wheel 23 and the tension wheel 26. When the polishing belt 28 is deformed by pressure, the two tension springs 25 can squeeze the two sliders 24 respectively, and the two sliders 24 will drive the tension wheel 26 to tighten the polishing belt 28.
