The rotating part has a speed reduction structure inside, and the rotating part is driven by a clamping chuck, which is used to clamp parts.
[0006] It also includes a drive assembly, which is connected to the speed reduction structure inside the rotating part, so that the clamping chuck carries the part to rotate axially; the drive assembly can be detached from the rotating part, and the rotating part after being detached from the drive assembly can rotate relative to the support, so that the machining surface of the part is transferred from the outer circle to the end face.
[0007] Preferably, the bracket has two bracket extensions, with the rotating part disposed between the two bracket extensions, and also includes a main shaft, which is installed at both ends of the rotating part and enters a circular hole provided at the bracket extension, so that the rotating part can rotate relative to the bracket after being disengaged from the drive assembly.
[0008] Preferably, the clamping chuck is also equipped with an indexing head, which is connected to the speed reduction structure inside the rotating part.
[0009] Preferably, the position of the rotating part relative to the bracket is adjustable and can be locked after adjustment.
[0010] Preferably, the drive assembly includes a motor, a motor bracket combined with a support, and a conveyor belt. The motor is fixed by the motor bracket, the motor transmission part is equipped with a first wheel, and the internal reduction structure of the rotating part is equipped with a second wheel. The second wheel extends outward from the support. The conveyor belt is fitted over the first wheel and the second wheel and is used to rotate the clamping chuck and the indexing head when the motor drives the first wheel to rotate.
[0011] Preferably, the second wheel can be detached from the rotating part, and after the second wheel is detached, the rotating part can rotate relative to the bracket.
[0012] The beneficial effects of this utility model are:
[0013] The fixture proposed in this utility model is mainly used on surface grinders. This fixture can not only expand the machining surface of the surface grinder, but also combine with the refinement requirements to make the machining surface of the part located on the end face or the outer circle, with a wider range of choices, and can further expand the applicability of the surface grinder.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Example 1
[0022] This embodiment presents a fixture for converting a manual surface grinder into a cylindrical grinder. Please refer to [link to relevant documentation]. Figures 1-4The fixture for this manual surface grinder modified into a cylindrical grinder includes a base 1, a support 2, and a rotating part 4. The base 1 has a curved groove on top, and the curved support 2 is positioned within this groove. The support 2 has two support extensions 12, and the rotating part 4 is positioned between the two support extensions 12. (See also...) Figure 2 and Figure 4 The bracket extension 12 also has a main shaft 5, which is installed at both ends of the rotating part 4 and extends into the circular holes provided in the bracket extension 12. The rotating part 4 has a reduction gear structure (not shown in the figure), and the rotating part 4 is connected to a clamping chuck 7, which can be used to clamp parts. In this embodiment, a drive assembly is also provided, which includes a motor 8, a motor bracket 3 that is coupled to the bracket 2 from the side of the bracket 2, and a conveyor belt 11. The motor 8 is fixed by the motor bracket 3, and the transmission part of the motor 8 is equipped with a first wheel 9. The reduction gear structure in the rotating part 4 is equipped with a second wheel 10, which extends outward from the bracket 2. The conveyor belt 11 is fitted around the first wheel 9 and the second wheel 10. Thus, when the motor 8 drives the first wheel 9 to rotate, the clamping chuck 7 can rotate, thereby driving the parts clamped by the clamping chuck 7 to rotate. Of course, in this embodiment, the part can be machined not only its outer diameter but also its end face. Specifically, the second wheel 10 can be detached from the rotating part 4. After the second wheel 10 is detached, the rotating part 4 can be rotated relative to the bracket 2 as follows: Figures 1 to 3 The rotation action shown in the figure transfers the machining surface of the part from the outer circle to the end face, and then the end face is machined in conjunction with the grinding disc in the surface grinder.
[0023] In this embodiment, it should be noted that the clamping chuck 7 is also equipped with an indexing head 6, which is connected to the speed reduction structure inside the rotating part 4. Thus, when the machining surface of the part is transferred from the outer circle to the end face, the clamping chuck 7 can be rotated along its axis via the indexing head 6, thereby fine-tuning the end face of the part. Furthermore, it should be noted that the position of the rotating part 4 relative to the support 2 is adjustable and can be locked after adjustment, using locking methods such as snap-fit or bolt connection.
[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
