[0001] The utility model relates to the technical field of cylindrical pin processing, in particular to an edge grinding device for cylindrical pin processing. Background Art

[0002] The cylindrical pin belongs to a positioning pin and is used to fix the relative positions between parts. It is an important auxiliary part during combined processing and assembly. When processing cylindrical pins, when one bottom surface of some cylindrical pins is flat while the other bottom surface is uneven, an edge grinding assembly needs to be used for grinding.

[0003] In some edge grinding devices, the cylindrical pin is often held manually by workers, and one bottom surface of it is brought into contact with the rotating grinding disc of the edge grinding assembly. However, this cannot ensure its flatness. Sometimes, due to hand shaking, the bottom surface of the cylindrical pin is easily ground and damaged, resulting in the scrapping of the workpiece.

[0012] The beneficial effects of the present utility model are as follows: By providing a placement plate on the workbench for placing the cylindrical pin body, and providing a rotating seat to enable the placement plate to rotate, the placement plate can rotate the placed cylindrical pin body to the grinding component below for grinding.

Detailed Description of the Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figure 1-6, A grinding edge device for processing cylindrical pins, including a workbench 001. On the upper surface support frame of the workbench 001, a grinding edge assembly 002 is provided. On the upper surface of the workbench 001, a rotating seat 4 is provided. On the rotating disk at the top of the rotating seat 4, a placing plate 1 is installed. The rotating seat 4 facilitates the rotation of the placing plate 1 around the rotating seat 4 as the axis.

[0022] Among them, an installation hole 12 is provided in the middle of the plate body of the placing plate 1. A plurality of positioning holes 11 are evenly opened on the plate body of the placing plate 1 outside the installation hole 12. On the column bodies at the ends of the bifurcated plate bodies of the placing plate 1, cylindrical pin insertion holes 14 with different diameters are provided. Cylindrical pin bodies 5 with the same aperture as the cylindrical pin insertion holes 14 are placed at the cylindrical pin insertion holes 14. The cylindrical pin insertion holes 114 with different diameters facilitate the placement of cylindrical pin bodies 5 of different sizes.

[0023] In addition, on the side wall of the plate body of the placing plate 1 on one side of the cylindrical pin insertion hole 14, a limiting plate 13 is fixedly connected. A through hole is provided on the limiting plate 13, and a limiting insertion rod 3 is inserted through the through hole of the limiting plate 13. The limiting plate 13 facilitates the installation of the limiting insertion rod 3.

[0024] Moreover, on the upper surface of the workbench 001, a limiting column 2 is vertically fixed on one side of the rotating seat 4. A limiting hole 21 is provided on the limiting column 2. The limiting hole 21 can be aligned with the center of the limiting plate 13. The aperture of the limiting hole 21 is the same as the diameter of the bottom rod body of the limiting insertion rod 3. The bottom rod body of the limiting insertion rod 3 can be inserted into the limiting hole 21. After the limiting insertion rod 3 is inserted into the limiting hole 21, it can prevent the placing plate 1 from rotating.

[0025] At the same time, a bolt hole 41 is provided in the middle of the upper surface of the rotating disk at the top of the rotating seat 4. A plurality of positioning columns 42 are evenly arranged on the upper surface of the rotating disk at the top of the rotating seat 4 outside the bolt hole 41. The diameter of the positioning column 42 is the same as the aperture of the positioning hole 11. The positioning column 42 and the positioning hole 11 can be centered and aligned. The fixing component 6 can be screwed into the bolt hole 41. The positioning column 42 cooperates with the positioning hole 11 to facilitate the more stable installation of the placing plate 1.

[0026] In this embodiment, when it is necessary to grind the edge of one side of the cylindrical pin body 5, this device can be used. The grinding edge assembly 002 is a device composed of a rotatable grinding disk. The grinding surface of the rotating grinding disk contacts the bottom surface of the cylindrical pin body 5 during rotation, thereby grinding it. This kind of grinding edge assembly 002 is prior art and is well-known to those in the grinding field, so the structure and principle thereof will not be elaborated in this article.

[0027] First, when installing the placement plate 1, ensure that each positioning post 42 is inserted into the positioning hole 11. Then, pass the fixing member 6 through the mounting hole 12 and screw it into the bolt hole 41 to fix the placement plate 1. Then, the user can select a cylindrical pin jack 14 that fits the diameter of the cylindrical pin body 5. Place the bottom surface of the cylindrical pin body 5 that needs to be polished facing up, and then insert it into the cylindrical pin jack 14. Then, rotate the placement plate 1 at this time to rotate the cylindrical pin body 5 that needs to be polished under the grinding disc of the edge grinding assembly 002. Ensure that the through hole on the limit plate 13 can be aligned with the limit hole 21, and the limit insertion rod 3 can pass through the through hole on the limit plate 13 and enter the limit hole 21. At this time, it can be ensured that the cylindrical pin body 5 is directly below the edge grinding assembly 002. After the limit insertion rod 3 is inserted into the limit hole 21, the placement plate 1 cannot rotate at this time, so as to ensure that the cylindrical pin body 5 does not shake during grinding.

[0028] In the present utility model, by providing a placement plate 1 on the workbench 001 that can place the cylindrical pin body 5, and the provided rotating seat 4 can realize the rotation of the placement plate 1. In this way, the placement plate 1 can rotate the placed cylindrical pin body 5 under the edge grinding assembly 002 for grinding. In this way, there is no need to manually hold the cylindrical pin body 5 for edge grinding work, which can ensure that the cylindrical pin body 5 will not be damaged during edge grinding. Moreover, the placement plate 1 can place multiple cylindrical pin bodies 5 of different sizes at one time, so that the placement plate 1 can be applicable to more sizes of cylindrical pin bodies 5.

[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
