Description

Technical Field

[0001] This utility model relates to the field of grinding head tools, and in particular to a flexible grinding and polishing small grinding head tool. Background Technology

[0002] With the development of industrial technology, small grinding tools are needed to polish precision optical components. These small grinding heads typically consist of a support section and a polishing disc. The support section, usually a spindle, supports the polishing disc and is connected to a power mechanism such as a motor. When the motor starts, it drives the polishing disc to rotate via the spindle. The polishing disc material can be asphalt, polyurethane, nylon cloth, etc. The polishing disc is used to polish the surface of an object. However, because the surface of precision optical components may be irregular with multiple protrusions, and the polishing disc is relatively large, it is difficult to control the polishing force manually or mechanically to conform to the object's surface during the polishing process. This makes it challenging to control the applied force, resulting in inconsistent polishing levels on the surface of the precision optical components after polishing. Furthermore, existing polishing discs and spindles are usually fixed as a single unit, making the polishing disc prone to wear. When the polishing disc wears out, the entire disc must be replaced, leading to high operating costs.

[0003] Therefore, it is necessary to propose a flexible polishing small grinding head tool to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible polishing small grinding head tool to solve the problem that the polishing disc is large in size, and the force applied during the polishing process is difficult to control manually or mechanically to fit the surface of the object. This results in inconsistent polishing of the surface of the precision optical components after polishing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible grinding and polishing small grinding head tool, including a grinding and polishing head, wherein the grinding and polishing head includes a first grinding and polishing component and a second grinding and polishing component, the first grinding and polishing component has a hemispherical structure, the second grinding and polishing component has a cylindrical structure, and the first grinding and polishing component and the second grinding and polishing component are spliced ​​together.

[0006] The first polishing component is used for elastic polishing of irregular areas on the surface of an object; the second polishing component is used for polishing flat areas on the surface of an object.

[0007] The second polished part has a circular groove on the side near the first polished part, and a spring is fixedly installed in the circular groove. The other end of the spring is fixedly connected to the first polished part.

[0008] Preferably, it also includes a connecting shaft, which is a cylindrical structure. The side of the second polished part away from the first polished part is provided with a mating groove, and one end of the connecting shaft extends into the mating groove.

[0009] Preferably, it also includes a central rod, which is a rod-shaped structure with a square cross-section;

[0010] The first polished part has a rectangular groove at one end near the second polished part, into which one end of the center rod can be movably inserted. The second polished part has a short rectangular hole inside, which connects the circular groove and the mating circular groove. The center rod moves through the short rectangular hole. The connecting shaft has a long rectangular hole inside, through which the center rod moves.

[0011] The connecting shaft and the central rod are connected by a screw and nut assembly.

[0012] Preferably, the central rod is provided with connecting holes for connecting screw and nut assemblies, and there are multiple connecting holes that are evenly distributed.

[0013] Preferably, the central rod is fixed to the short rectangular hole by adhesive.

[0014] Preferably, a gap is left between the rectangular groove and the end of the central rod.

[0015] Preferably, a gap is left between the first polished part and the second polished part.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] The elastic polishing head tool in this utility model can automatically adapt to the irregular surface of the object and achieve the effect of elastic polishing. Only by controlling a fixed force and holding the elastic polishing head tool, a relatively uniform polished surface can be produced.

[0018] When the first or second grinding / polishing part is severely worn, the elastic grinding / polishing head tool of this utility model can be replaced with a new grinding / polishing head without the need for complete replacement, thus saving on usage costs.

[0019] In the elastic polishing head tool of this utility model, there is a certain gap between the first polishing component and the second polishing component. When the polishing head rotates as a whole, it drives the air force to enter the gap between the first polishing component and the second polishing component, which can increase the heat dissipation effect and avoid excessive heat loss of the polishing head.

Detailed Implementation

[0026] This utility model provides, for example Figures 1-5 The invention relates to a flexible polishing head tool, which can achieve flexible polishing of irregular surfaces, increase the fit between the flexible polishing head tool and the object surface, and can be partially replaced when the flexible polishing head tool is damaged, without the need for complete replacement, thus saving on usage costs.

[0027] refer to Figure 1 and Figure 2 As shown, the flexible polishing small grinding head tool mainly includes a polishing part, a connecting part, and a supporting part.

[0028] Among them, reference Figure 3 As shown, the grinding and polishing part includes a grinding and polishing head 1, which is composed of a first grinding and polishing component 101 and a second grinding and polishing component 102. The first grinding and polishing component 101 has a hemispherical structure, and the second grinding and polishing component 102 has a cylindrical structure. The first grinding and polishing component 101 and the second grinding and polishing component 102 are spliced ​​together. The first grinding and polishing component 101 is used to elastically grind irregular positions on the surface of the object, and the second grinding and polishing component 102 is used to grind flat positions on the surface of the object.

[0029] refer to Figure 4As shown, a circular groove 1021 is provided on the side of the second polishing part 102 near the first polishing part 101. A spring 1012 is fixedly installed in the circular groove 1021. The other end of the spring 1012 is fixedly connected to the first polishing part 101. The first polishing part 101 can move along the axial direction of the second polishing part 102. When the first polishing part 101 is used to polish the surface of the object, when the first polishing part 101 comes into contact with the irregular protrusions on the surface of the object, the first polishing part 101 is pushed against and compresses the spring 1012, so that the first polishing part 101 moves within a certain range along the axial direction of the second polishing part 102 to avoid it, automatically adapting to the irregular surface of the object. Only a fixed force needs to be controlled to hold the elastic polishing small grinding head tool to polish, and a relatively uniform polished surface can be polished.

[0030] Among them, reference Figure 1 and Figure 2 As shown, the support part includes a connecting shaft 2, which is a cylindrical structure. The side of the second polishing part 102 away from the first polishing part 101 is provided with a mating groove 1023. One end of the connecting shaft 2 extends into the mating groove 1023, and the other end of the connecting shaft 2 is connected to an external power mechanism such as a motor. When the power mechanism is started, it can drive the connecting shaft 2 to rotate.

[0031] refer to Figure 1 , Figure 2 and Figure 5 As shown, the connecting part includes a central rod 4, which is a rod-shaped structure with a square cross-section. The first polishing part 101 is provided with a rectangular groove 1011 at one end near the second polishing part 102, into which one end of the central rod 4 can be movably inserted. The second polishing part 102 is provided with a short rectangular hole 1022 inside, through which the central rod 4 can be movably passed. The short rectangular hole 1022 is connected between the circular groove 1021 and the mating circular groove 1023. The connecting shaft 2 is provided with a long rectangular hole 201 inside, through which the central rod 4 can be movably passed.

[0032] The central rod 4 is provided with multiple connecting holes 401, which are evenly distributed. The connecting shaft 2 is provided with a screw and nut assembly 3, which includes a screw and a nut. The screw is connected to the corresponding connecting hole 401, thereby fixing the connecting shaft 2 and the central rod 4. The nut is connected to both ends of the screw through a threaded engagement, thus completing the positioning of the screw and nut assembly 3.

[0033] The center rod 4 is fixed by adhesive at the position where it passes through the short rectangular hole 1022, forming a stable structure.

[0034] When the power mechanism drives the connecting shaft 2 to rotate, the connecting shaft 2, the central rod 4, and the polishing head 1 all rotate as a whole, which can polish the surface of the object.

[0035] When polishing a relatively smooth surface on an object, polishing can be performed through the outer ring of the second polishing part 102.

[0036] When polishing an irregular surface on an object, the outer surface of the first polishing part 101 can be used for polishing. If there are protrusions or depressions during the polishing process, the first polishing part 101 will compress or release the spring 1012, so that the first polishing part 101 moves along the axial direction of the second polishing part 102, and stretches and avoids within a certain range, thus achieving the effect of elastic polishing.

[0037] It should be noted that when the first polishing part 101 or the second polishing part 102 is severely worn, the screw and nut assembly 3 can be removed, the center rod 4 can be taken out from the polishing head 1 and the connecting shaft 2, a new polishing head 1 can be replaced, and then the polishing head 1 can be fitted onto the end of the center rod 4. The short rectangular hole 1022 and the center rod 4 can be fixed with glue. There is no need to replace the whole thing, which saves on usage costs.

[0038] It should also be noted that a certain gap is left between the end of the center rod 4 and the rectangular groove 1011, allowing the first polishing part 101 to extend and retract within a certain range. The extension and retraction distance of the first polishing part 101 is less than the depth of this gap, so as to prevent the center rod 4 from detaching from the rectangular groove 1011.

[0039] There is a certain gap between the first polishing part 101 and the second polishing part 102. When the polishing head 1 rotates as a whole, it drives the air force to enter the gap between the first polishing part 101 and the second polishing part 102, which can increase the heat dissipation effect and avoid excessive heat loss of the polishing head 1.

[0040] When the screw and nut assembly 3 is fixed in different connecting holes 401, the overall length of the elastic polishing small grinding head tool can be adjusted to facilitate adjustment and use according to actual needs.
