[0020] Please refer to Figure 1 , Figure 2This utility model discloses a polishing device for processing hydrogen sulfide corrosion resistant samples. It includes a drive wheel 3, a central connecting rod 4, an offset connecting rod 5, a sliding rod 6, and a clamp 7. The central connecting rod 4 is fixedly mounted on a lathe 2. The drive wheel 3 is rotatably mounted on the central connecting rod 4 via a central locating pin 31. The offset connecting rod 5 is hinged to the side of the drive wheel 3 away from the central connecting rod 4, with the hinge axis parallel to but not coinciding with the rotation axis of the drive wheel 3. The central connecting rod 4 has a guiding mechanism. One end of the sliding rod 6 is hinged to the end of the offset connecting rod 5 away from the drive wheel 3, and the other end slides in engagement with the guiding mechanism. The drive wheel 3 is driven by the lathe 2 and, through the offset connecting rod 5, drives the sliding rod 6 to reciprocate in the direction defined by the guiding mechanism. The clamp 7 is mounted on the sliding rod 6 and is used to hold the polishing tool.

[0021] When the drive wheel 3 rotates, the axis of the biasing link 5 rotates around the axis of the drive wheel 3, thereby driving the sliding rod 6 to move. Since the sliding rod 6 passes through the guide groove 45 and one end is hinged to the biasing link 5, the sliding rod 6 can reciprocate along the direction defined by the guide groove 45, driving the polishing tool mounted on it to reciprocate, polishing the sample. The polishing tool includes polishing cloth, polishing paste, etc.

[0022] Specifically, the eccentric link 5 and the drive wheel 3 can be connected by an eccentric locating pin 51. The axis of the eccentric locating pin 51 is parallel to the axis of the drive wheel 3. The eccentric locating pin 51 is fixedly connected to the drive wheel 3 and rotatably engaged with the eccentric link 71. In some other embodiments of this utility model, the eccentric locating pin 51 can also be replaced by other suitable components such as a hinge shaft.

[0023] The sliding rod 6 and the biasing link 5 can be connected by a locating pin 52, the axis of which is parallel to the axis of the eccentric locating pin 51. The locating pin 52 has a rotatable fit with both the sliding rod 6 and the biasing link 5. Similarly, the locating pin 52 can be replaced by other suitable components such as a hinge shaft.

[0024] Please continue to refer to Figure 1 , Figure 2 In a preferred embodiment of this utility model, the central connecting rod 4 includes a connecting portion 41, a first guide portion 42, a middle portion 43, and a second guide portion 44. The connecting portion 41 is connected to the drive wheel 3 via a central positioning pin 31. One end of the first guide portion 42 is fixedly connected to the end of the connecting portion 41 away from the drive wheel 3 and is perpendicular to the connecting portion 41. One end of the middle portion 43 is fixedly connected to the end of the first guide portion 42 away from the connecting portion 41, and the other end is connected to one end of the second guide portion 44. The second guide portion 44 is parallel to the first guide portion 42 and located on the same side of the middle portion 43. Guide grooves 45 are provided on both the first guide portion 42 and the second guide portion 44. Thus, the first guide portion 42, the middle portion 43, and the second guide portion 44 form a guiding mechanism. A clamp 7 is mounted on the middle portion 43.

[0025] Specifically, the dimensions of the two guide grooves 45 are adapted to the dimensions of the sliding rod 6, so that the sliding rod 6 can slide within the two guide grooves 45 and be limited by the two guide grooves 45, making it less likely to wobble during sliding.

[0026] In another embodiment of this utility model, the guiding mechanism can also be a ring disposed on the first guide portion 42 and the second guide portion 43, with the two rings coaxial and their dimensions adapted to the dimensions of the sliding rod 6. The sliding rod 6 passes through the two rings and slides with them. In some other embodiments of this utility model, the guiding mechanism can also adopt other suitable components that can both slide with the sliding rod 6 and limit the movement direction of the sliding rod 6, which will not be described in detail here.

[0027] By setting the part of the central connecting rod 4 away from the drive wheel 3 into a "U" shape, the clamp 7 can be installed between the first guide part 42 and the second guide part 44, which reduces the space occupied by the clamp 7 and is conducive to the miniaturization of the device.

[0028] The clamp 7 is connected to the intermediate part 43 via a connecting block 8. The connecting block 8 is detachably connected to both the intermediate part 43 and the clamp 7. In a preferred embodiment of this invention, the connecting block 8 is rectangular in shape and is connected to the intermediate part 43 via at least two bolts and to the clamp 7 via a fixing pin 81. This allows for quick assembly and disassembly of the clamp 7, sliding rod 6, and connecting block 8, facilitating the replacement or maintenance of the clamp 7.

[0029] More specifically, the clamp 7 includes a connecting rod 71 and a clamping part 72. One end of the connecting rod 71 is detachably connected to the connecting block 8. The other end is hinged to the clamping part 72 via a connecting joint 9, allowing the angle of the clamping part 72 relative to the connecting rod 71 to be adjustable. The clamping part 72 is used to clamp polishing tools. The connecting rod 71 is connected to the intermediate part 43 via a fixing pin 81. The connecting joint 9 can be a pivot or a locking bolt. That is, the clamp 7 is connected to the connecting rod 71 via a pivot, and the pivot can be locked by a locking bolt, allowing the angle of the clamp 7 to be adjusted, and after being adjusted to a suitable angle, it can be locked by the locking bolt to prevent the clamp 7 from loosening during use.

[0030] To further improve the stability of the clamp 7, the clamp 7 also includes a fixing rod 73. The fixing rod 73 is mounted on the connecting block 8, with both ends bent away from the middle part 43. Both ends of the fixing rod 73 are threaded with limit bolts 74. The two limit bolts 74 are coaxial, and their tails are positioned opposite each other.

[0031] Specifically, both ends of the fixing rod 73 are bent to form mounting portions 731. The mounting portion 731 is formed by extending the end of the fixing rod 73 upward from the fixing rod 73, then extending horizontally in a direction away from the other mounting portion 731, and finally extending upward again to form a "Z"-shaped structure rotated 90°. This shape of the mounting portion 731 helps to reduce the space occupied by the fixing rod 73 and facilitates the miniaturization of the device.

[0032] The working principle of the polishing device for processing hydrogen sulfide corrosion resistant samples of this utility model is as follows: Before polishing, the sample is clamped on the fixture 7, and then the lathe 2 is started, which drives the drive wheel 3 to rotate. The rotation of the drive wheel 3 can drive the axis of the biasing connecting rod 5 to rotate around the axis of the drive wheel 3, thereby driving the sliding rod 6 to move. Since the sliding rod 6 passes through the guide groove 45 and one end of it is hinged to the biasing connecting rod 5, the sliding rod 6 can reciprocate along the direction defined by the guide groove 45, driving the polishing tool mounted on it to reciprocate, thus polishing the sample.

[0033] Compared with existing technologies, the polishing device for processing hydrogen sulfide corrosion resistant samples of this invention can replace manual polishing of samples, achieve human-machine isolation, reduce the safety risks of direct contact between people and mechanical equipment, and also achieve automated operation, reducing the labor intensity of workers. Furthermore, compared with manual polishing, the polishing device for processing hydrogen sulfide corrosion resistant samples of this invention uses a linkage of mechanical structures to polish, which helps to improve the consistency and accuracy of sample polishing.

[0034] Based on the above concept, such as Figure 3 As shown, this utility model also discloses a polishing lathe, including the aforementioned polishing device 1 for processing hydrogen sulfide corrosion resistant samples. By using the polishing device 1 for processing hydrogen sulfide corrosion resistant samples, this polishing lathe can replace manual polishing of the samples, offering good safety and high consistency and precision in polishing.

[0035] Figure 3 In the diagram, the part within the dashed box is the polishing device 1 used for processing samples resistant to hydrogen sulfide corrosion, while the remaining part is the lathe 2.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
