Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing, and in particular to a polishing device for a stainless steel adjusting rod. Background Art

[0002] In the field of grinding and polishing, the processing of stainless steel adjusting rods is a typical application case, which involves the characteristics of high material hardness and strict surface finish requirements. Traditional handheld grinders, with their efficient cutting ability and rapid material removal characteristics, perform well in processing local excess materials such as chamfers or burrs of stainless steel adjusting rods. Their high-speed rotating grinding wheels can quickly cut off unnecessary parts and improve work efficiency. However, when faced with the need to clean and polish the outer wall of stainless steel adjusting rods, the limitations of the grinding wheel gradually emerge: on the one hand, it is difficult for the grinding wheel to maintain a uniform and consistent processing effect when processing large-area continuous surfaces, and it is easy to leave spiral marks or damage the surface; on the other hand, the rough grinding nature of the grinding wheel seems to be unable to cope with the processing of subtle parts or those requiring extremely high surface finish.

[0003] Belt sanding technology shows unique advantages in this context. With its uniform distribution of abrasive grains, adjustable softness and low heat generation rate, abrasive belts are very suitable for detailed cleaning and polishing of exterior walls. Especially for materials such as stainless steel that have strict requirements on aesthetics and corrosion resistance, abrasive belts can provide more delicate surface treatment, effectively remove minor defects, improve surface flatness and brightness, and reduce damage to the material base.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1

[0034] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a polishing device for a stainless steel adjusting rod, including a power component 100, including a shell 101 and a motor 102 arranged inside the shell 101, and an additional component 200, which is added to the power component 100, and includes a sleeve 201 installed on the output shaft of the motor 102 and a cover body 202 installed on the shell 101, a grinding wheel 203 and a slidable and extendable sanding belt member 204 are arranged in the cover body 202, the grinding wheel 203 and the sanding belt member 204 are both rotated by the sleeve 201, a switching member 205 for switching the working state of the grinding wheel 203 and the sanding belt member 204 is arranged in the sleeve 201, and the switching member 205 is connected to the sanding belt member 204.

[0035] In view of the limitations of existing grinding wheel grinders in processing complex workpieces such as stainless steel adjusting rods, we proposed an improvement plan to achieve the integration and instant switching of the grinding wheel and the grinding belt functions, and improve the applicability and processing efficiency of the equipment. The key to this improvement lies in the optimization of the cover body 202 structure and the design of the output shaft of the motor 102.

[0036] In order to further optimize space utilization and safety, we set a slide rail structure (slide groove 202a) in the original protective cover body 202. In addition to retaining the original protective function of the cover body 202, the sand belt piece 204 is allowed to be completely retracted into the cover body 202 when not in operation, which not only protects the sand belt piece 204 from accidental damage and is properly preserved in the non-working state, but also ensures the normal use of the grinding wheel 203 after the sand belt piece 204 is retracted. When the sand belt needs to be used for fine work, the operator only needs to gently push the sand belt piece 204 along the slide groove 202a, and the sand belt piece 204 will automatically cover the original working area of ​​the grinding wheel 203. In particular, the sand belt piece 204 is designed to be distributed in a triangular shape, which not only expands the grinding coverage area and ensures that the original working area of ​​the grinding wheel 203 is shielded, but also realizes the adaptive adjustment of the tightness, which can fit closely with the outer wall of the stainless steel adjustment rod, and both the curved surface and the straight line part can be processed evenly and efficiently.

[0037] We realize the diversification of power transmission by adding a sleeve 201 to the output shaft of the existing motor 102. A switching member 205 is embedded in the sleeve 201, and the switching member 205 can flexibly select two different power parts connected to the sleeve 201 - the grinding wheel 203 dedicated to rough processing and the sanding belt drive wheel (first wheel 204a) suitable for fine grinding. This design enables a single power source to efficiently and smoothly switch between the grinding wheel 203 and the sanding belt 204 according to the working requirements.

[0038] Specifically, in order to realize the automatic switching between the grinding wheel 203 and the abrasive belt 204, the end of the straight rod of the abrasive belt 204 is connected to the switching member 205 inside the sleeve 201. When the abrasive belt 204 slides out of the working position, the switching member 205 automatically disconnects from the grinding wheel 203 and starts the linkage with the abrasive belt driving wheel (the first wheel 204a), and vice versa, ensuring a seamless transition between the two grinding modes. This design significantly improves the flexibility of the operation, reduces the time and labor intensity of manual tool replacement, and improves the overall processing efficiency and accuracy.

[0039] In summary, this improvement scheme successfully integrates the functions of the grinding wheel 203 and the abrasive belt through innovative mechanical design, which not only meets the diversified processing requirements of different parts of the stainless steel adjusting rod, but also greatly improves the operation convenience and processing efficiency of the equipment through the automatic switching mechanism.

[0040] Example 2

[0041] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the abrasive belt member 204 includes a first wheel 204a installed on the sleeve 201, a second wheel 204b and a third wheel 204c sliding along the cover body 202, a belt body 204d is sleeved between the first wheel 204a, the second wheel 204b and the third wheel 204c, a straight plate 204e is provided between the first wheel 204a and the second wheel 204b, and an arc plate 204f is provided between the second wheel 204b and the third wheel 204c. The cover body 202 is provided with a slide groove 202a, the second wheel 204b slides along the first rotating rod 204g inside, a fastening nut 204h for locking the position is arranged on the outside of the first rotating rod 204g, an arc groove 204i is provided on the arc plate 204f, the third wheel 204c slides along the second rotating rod 204j through one end inside, a first spring is arranged on the arc plate 204f, and the first spring is used to push the second rotating rod 204j to move outward to move the belt body 204d. The straight plate 204e is located on the outside of the sand belt member 204, the arc plate 204f is located on the inside of the sand belt member 204, and the arc opening of the arc plate 204f faces outward.

[0042] It should be noted that the core of the abrasive belt 204 is composed of three parts: the first wheel 204a rotatably arranged on the sleeve 201 is used as a driving wheel to provide power for the entire abrasive belt; the second wheel 204b slides along the slide groove 202a inside the cover 202, and the third wheel 204c slides with the second wheel 204b through the arc plate 204f to realize the dynamic expansion and retraction of the abrasive belt 204 in the cover 202. The three wheels are distributed in a triangular shape, the first wheel 204a is fixed to ensure continuous power output, and the second and third wheels work together to achieve effective support and flexible adjustment of the belt body 204d through the cooperation of the straight plate 204e and the arc plate 204f. The third wheel 204c can automatically adjust the tightness of the belt body 204d with the help of the second rotating rod 204j and the first spring installed on the arc plate 204f to adapt to the pressure changes on the surfaces of different workpieces and ensure the uniformity and consistency of the grinding effect.

[0043] The design of the arc plate 204f is particularly critical. Through its specific arc opening design facing outward, it not only provides a buffer space for the pressure of the workpiece on the abrasive belt, making it easier for the abrasive belt to fit closely to the workpiece surface, but also further limits the excessive penetration of the workpiece to prevent it from touching the internal grinding wheel 203.

[0044] In summary, the abrasive belt component 204 realizes the rapid deployment and precise positioning of the abrasive belt, which not only improves the versatility and operating efficiency of the equipment, but also ensures the safety and flexibility of operation through a series of sophisticated mechanical linkages, providing a solution for the efficient grinding of complex workpieces such as stainless steel adjusting rods.

[0045] The specific operation process is as follows: first, loosen the fastening nut 204h so that the first rotating rod 204g can move freely in the slide groove 202a, and then drive the second wheel 204b to slide along the slide groove 202a by moving the first rotating rod 204g. This action not only causes the straight plate 204e to cause the belt body 204d to deflect, but also drives the third wheel 204c to move synchronously through the arc plate 204f structure between the second wheel 204b and the third wheel 204c, so that the entire belt body 204d rotates and unfolds around the first wheel 204a, and the third wheel 204c and the corresponding part of the belt body 204d are smoothly extended out of the cover body 202 to cover the original working area of ​​the grinding wheel 203, which is used for the operation of grinding and polishing by using the grinding belt piece 204 instead of the grinding wheel 203. This design also ensures that when the grinding belt is operating, a sufficient distance is maintained between the workpiece and the grinding wheel 203 to avoid accidental contact and ensure operational safety.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3

[0048] Reference Figure 1-Figure 6, which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the outer wall of the sleeve 201 is provided with a baffle 206, a grinding wheel 203, a transmission plate 207 and a first wheel 204a in sequence from the inside to the outside, the baffle 206 is rotatably arranged on the sleeve 201, the grinding wheel 203 and the first wheel 204a are both sleeved on the outer wall of the sleeve 201, and the transmission plate 207 is detachably installed on the grinding wheel 203. The switching member 205 includes a fixed shaft 205b installed at one end of the plug 205a, the outer wall of the fixed shaft 205b is sleeved with a ring body 205c, the outer wall of the ring body 205c is provided with a telescopic plug rod 205d, the telescopic plug rod 205d is inserted into the insertion hole 207a on the inner wall of the transmission plate 207, and the inner wall of the sleeve 201 is provided with a limiting groove 201a, and the telescopic plug rod 205d slides along the limiting groove 201a. A connecting rod 205e connected to the ring body 205c is arranged on one side of the fixed shaft 205b and is connected to the ring body 205c through a bearing. The side of the grinding wheel 203 or the first wheel 204a is provided with a lock hole 207c, and the left and right sides of the transmission plate 207 are provided with a locking rod 207b, which is plugged into the lock hole 207c. A plug 205a is plugged into the outer end of the sleeve 201, and the lower end of the straight plate 204e is installed on the plug 205a, and the upper end of the straight plate 204e slides along the outer side groove 202a of the cover body 202, and the outer side groove 202a gradually deviates outward along the extension direction of the abrasive belt member 204, which is used to drive the straight plate 204e to gradually move outward, and to drive the plug 205a to rotate and move in the sleeve 201.

[0049] It should be noted that: multiple core components are arranged on the outer wall of the sleeve 201: the inner layer is the baffle 206, which is responsible for the positioning and stabilization of the grinding wheel 203; outside the baffle 206 are the grinding wheel 203 and the first wheel 204a (sand belt driving wheel) that can be directly sleeved on the sleeve 201. They are not directly linked with the sleeve 201, and the task of power transmission is given to the transmission plate 207 sliding between the two. The transmission plate 207 flexibly docks with one of the grinding wheel 203 or the first wheel 204a to ensure smooth power conversion. The transmission plate 207 has a preset socket 207a, which is closely matched with the telescopic plug rod 205d, which not only facilitates the installation and removal of the transmission plate 207, but also provides a convenient channel for the replacement of the grinding wheel 203.

[0050] The core component of the switching mechanism is a fixed shaft 205b, which is connected to the plug 205a. The plug 205a is inserted into the opening at the end of the sleeve 201. At the same time, the lower part of the straight plate 204e is also bound to the plug 205a, so that the movement of the straight plate 204e can be transmitted to the fixed shaft 205b through the plug 205a. One side of the fixed shaft 205b is connected to the ring body 205c through a connecting rod 205e with a bearing. The outer wall of the ring body 205c is fixed with a telescopic plug 205d. The telescopic plug 205d slides axially under the guidance of the limit groove 201a in the sleeve 201, thereby controlling the horizontal movement of the transmission plate 207 between the grinding wheel 203 and the first wheel 204a, and realizing the precise switching of power. In this process, the locking rods 207b on both sides of the transmission plate 207 perfectly match the locking holes 207c on the grinding wheel 203 and the first wheel 204a, ensuring the stability of the power connection and the accuracy of the switching.

[0051] The key to the operation mechanism lies in the interaction between the straight plate 204e and the outer slide groove 202a. The upper end of the straight plate 204e slides along the specially designed slide groove 202a on the outer side of the cover body 202. The slide groove 202a gradually widens as the sanding belt 204 is extended outward, ensuring that when the straight plate 204e moves outward, it not only slides smoothly, but also effectively drives the plug 205a to rotate and translate in the sleeve 201. This series of actions, through the chain reaction of the connecting rod 205e-ring body 205c-telescopic plug 205d, ultimately adjusts the position of the transmission plate 207, thereby seamlessly switching the power transmission path between the grinding wheel 203 and the first wheel 204a. The whole process is both ingenious and efficient.

[0052] The mechanical linkage mechanism of the sanding belt 204 during the expansion process is as follows: when the sanding belt 204 expands outward along the slide groove 202a on the cover body 202, the second wheel 204b drives the upper end of the straight plate 204e to rotate accordingly, and the plug 205a fixed at the lower end of the straight rod rotates inside the sleeve 201. As the upper end of the straight plate 204e slides along the outer oblique slide groove 202a, the distance between the straight plate 204e and the first wheel 204a gradually increases, and the plug 205a is also pulled outward from the sleeve 201 with the action of the straight plate 204e. The movement of the plug 205a drives The fixed shaft 205b moves outwards together with the fixed shaft 205b, and this movement is transmitted to the telescopic rod 205d through the connecting rod 205e, so that it moves outwards along the limit groove 201a on the sleeve 201. The outward movement of the telescopic rod 205d not only pulls the transmission plate 207 to move together, but also makes the locking rod 207b on one side of the transmission plate 207 disengage from the locking hole 207c of the grinding wheel 203. At the same time, the locking rod 207b on the other side of the transmission plate 207 is plugged and engaged with the locking hole 207c on the side of the first wheel 204a, ensuring the firm connection between the transmission plate 207 and the first wheel 204a. Therefore, when the motor 102 drives the sleeve 201 to rotate, the power is transmitted to the transmission plate 207 and the first wheel 204a through the telescopic rod 205d, thereby driving the entire abrasive belt assembly (including the second wheel 204b, the third wheel 204c and the belt body 204d) to rotate, so as to achieve efficient grinding and polishing of the abrasive belt.

[0053] On the contrary, when the abrasive belt 204 is recovered, the process is reversed: the straight plate 204e slides back along the outer slide groove 202a, driving the plug 205a to return to the deep of the sleeve 201, and then driving the shaft to move inward. This action is transmitted through the connecting rod 205e, prompting the telescopic plug 205d to slide inward, driving the transmission plate 207 to move inward, separating it from the first wheel 204a, and re-locking it with the grinding wheel 203, completing the automatic switching of the power source from the abrasive belt drive to the grinding wheel 203, ensuring the smooth conversion of the equipment between the abrasive belt and the grinding wheel 203 functions according to different operating requirements.

[0054] The remaining structure is the same as that of Example 2.
