Detailed Description of the Embodiment

[0024] The present application will be further described in detail below with reference to the drawings.

[0025] Refer to Figure 1 and Figure 2, a V - surface grinding positioning device disclosed in the present application, includes a base 1, a mounting part 2, and a fixing part 3. The base 1 is installed on the mounting part 2. There is a support groove 11 on the base 1, and the support groove 11 is used to cooperate with the fixing part 3 to form a pressing cavity. The support groove 11 includes two groups of contact surfaces 12. The mounting part 2 is used to connect other structures. The base 1 and the fixing part 3 form a pressing cavity, and the workpiece 6 is located in the pressing cavity. In this embodiment, the number of adjusting members 5 is two groups, and the adjusting members 5 can be bolts.

[0026] When pressing the workpiece 6, first place the workpiece 6 in the support groove 11 to contact the contact surface 12, and rotate the adjusting member 5 so that the workpiece 6 is pressed. After the processing is completed, rotate the adjusting member 5 in the reverse direction so that the pressing member 4 moves away from the base 1, thereby loosening the workpiece 6.

[0027] Refer to Figure 3 and Figure 4 , in another embodiment, it further includes a driving member 7 and a measuring part 8. The pressing member 4 includes a connecting plate 42 and a pressing plate. The driving member 7 is installed on the connecting plate 42, and the driving member 7 is used to drive the pressing plate to move vertically. The adjusting member 5 adjusts the distance between the connecting plate 42 and the base 1. The pressing plate is slidably connected to the adjusting member 5. In this embodiment, the driving member 7 can be a cylinder or an electric push rod. There are two groups of adjusting members 5. The adjusting member 5 includes a lead screw and a nut. The nuts are provided on the bottom surface and the top surface of the connecting plate 42 for adjusting the position of the pressing plate on the lead screw.

[0028] The measuring part 8 includes a pressing rod 81 and an indicating rod 82. There is a first groove 13 and a second groove 14 on the base 1. The first groove 13 is used to accommodate the pressing rod 81, and the second groove 14 is used to accommodate the indicating rod 82. The pressing rod 81 is installed on the pressing member 4 and moves vertically with the pressing member 4. One end of the indicating rod 82 is in contact with the pressing rod 81 and moves horizontally under the drive of the pressing rod 81. The indicating rod 82 is provided with a scale at the end far from the pressing rod 81. The pressing rod 81 is provided with a guiding surface 83, and the guiding surface 83 is set as an inclined surface. The guiding surface 83 is used to contact the indicating rod 82. The indicating rod 82 is provided with an arc surface, and the arc surface is used to guide the pressing rod 81 to push the indicating rod 82. A reset member is provided at the end of the indicating rod 82 in contact with the guiding surface 83.

[0029] When pressing the workpiece 6, first place the workpiece 6 in the support groove 11. The driving member 7 drives the pressing plate to move downward to press the workpiece 6, so that the pressing rod 81 moves downward, and the indicating rod 82 moves horizontally under the drive of the pressing rod 81. The pressing degree of the workpiece 6 can be determined by observing the length of the indicating rod 82 extending out. The distance between the pressing member 4 and the base 1 is finely adjusted by rotating the nuts provided on the bottom surface and the top surface of the connecting plate 42. When the workpiece 6 needs to be loosened, the driving member 7 drives the pressing plate to move upward to loosen the workpiece 6.

[0030] The driving member 7 moves upward, causing the pressing rod 81 to move upward. The reset member on the indicating rod 82 is adsorbed on the guiding surface 83, causing it to move horizontally under the drive of the pressing rod 81, so that one end of the indicating rod 82 approaches the base 1. After the pressing rod 81 and the indicating rod 82 are separated, the indicating rod 82 can be manually reset.

[0031] The implementation principle of this embodiment is as follows: The adjusting member 5 adjusts the position of the connecting plate 42, so that the distance between the pressing member 4 and the base 1 can be adjusted, thereby adjusting the pressing degree of the workpiece 6. The driving member 7 drives the pressing member 4 to move vertically, so that the workpiece 6 can be pressed or released, making the workpiece 6 firmly fixed and easier to replace. During the grinding process, the workpiece 6 is more stable, thus improving the grinding accuracy of the workpiece 6.

[0032] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
