[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4A part processing fixing frame which is convenient for positioning comprises a bottom plate 1 and a workpiece 3 to be processed. A base 31 is arranged at the bottom of the workpiece 3 to be processed, and a mounting cavity 32 is opened downward at the top of the bottom plate 1. The mounting cavity 32 is adapted to the base 31, and a limiting plate 2 is adapted to be installed above the bottom plate 1; a limiting cavity 21 is adapted to be opened at the middle part of the limiting plate 2 corresponding to the workpiece 3 to be processed, and fixing cavities 22 are opened around the limiting cavity 21 on the limiting plate 2, and positioning columns 5 are arranged downward around the outer side of the limiting plate 2.

[0020] Among them, a plurality of fixing columns 6 are arranged upward on the outside of the installation cavity 32 above the bottom plate 1, and the tops of the fixing columns 6 are connected with threaded columns 61, and the fixing columns 6 are arranged corresponding to the fixing cavities 22. The diameter and height of the fixing columns 6 are the same as those of the fixing cavities 22, and the limiting plate 2 can be initially limited by the setting of the fixing columns 6.

[0021] The top of the threaded column 61 is adapted to be provided with a limiting sleeve 4, the diameter of which is larger than the diameter of the fixing cavity 22, and the bottom of the limiting sleeve 4 is adapted to be provided with a threaded cavity 41 corresponding to the threaded column 61. By sleeve-mounting the limiting sleeve 4 on the threaded column 61, the limiting plate 2 can be fixed to prevent the limiting plate 2 from moving in the upward and downward directions, and an anti-slip sleeve is provided on the outer side of the limiting sleeve 4.

[0022] Among them, the bottom plate 1 is provided with a plurality of positioning cavities 51 downwardly outside the installation cavity 32, and the positioning cavities 51 are all adapted to the positioning posts 5. Through the arrangement of the positioning cavities 51 and the positioning posts 5, the limiting plate 2 can be positioned when it is installed, so as to facilitate the installation by the user.

[0023] When the limit plate 2 is mounted on the bottom plate 1, the positioning posts 5 are inserted into the positioning cavity 51, and the threaded posts 61 on the fixing posts 6 pass through the fixing cavity 22. By setting the positioning posts 5 and the limit posts 6, the limit plate 2 can be clamped to prevent the limit plate 2 from rotating and moving in the horizontal direction.

[0024] The size of the workpiece 3 to be processed is smaller than that of the base 31, the mounting cavity 32 is adapted to the workpiece 3 to be processed, and the limiting cavity 21 is adapted to the workpiece 3 to be processed. The height of the base 31 is the same as that of the mounting cavity 32, and when the base 31 below the workpiece 3 to be processed is installed in the mounting cavity 32, the bottom of the workpiece 3 to be processed is flush with the top surface of the bottom plate 1.

[0025] In this embodiment, a base 31 is provided at the bottom of the workpiece 3 to be processed, and a mounting cavity 32 is provided downwardly on the top of the bottom plate 1, the mounting cavity 32 is adapted to the base 31, and a limit plate 2 is adapted to be installed on the top of the bottom plate 1. A limit cavity 21 is adapted to be provided in the middle of the limit plate 2 corresponding to the workpiece 3 to be processed, and a fixing cavity 22 is provided around the limit cavity 21 on the limit plate 2, and positioning columns 5 are provided downwardly around the outer side of the limit plate 2. The workpiece 3 to be processed can be clamped by the setting of the limit plate 2, and the limit plate 2 can be fixed by the limit sleeve 4, so that the fixation of the workpiece 3 to be processed can be completed.

[0026] Furthermore, when the user needs to fix the workpiece 3 to be processed, the base 31 at the bottom of the workpiece 3 to be processed can be directly placed into the installation cavity 32, and the bottom of the workpiece 3 to be processed is flush with the top surface of the bottom plate 1. Then, the positioning columns 5 under the limiting plate 2 are aligned with the positioning cavity 51 and inserted into it. At this time, the limiting cavity 21 is located on the outside of the workpiece 3 to be processed, and the base 31 is clamped. And in the process of the limiting plate 2 moving downward, the threaded columns 61 on the fixing columns 6 all pass through the fixing cavity 22, and the fixing columns 6 are located in the fixing cavity 22. Then, the user sets the limiting sleeve 4 on the threaded column 61 through the limiting cavity 41 at its bottom. It is worth noting that when the limiting sleeve 4 is completely set on the threaded column 61, the bottom of the limiting sleeve 4 contacts the limiting plate 2, so that the limiting plate 2 can be fixed in the upper and lower directions. Thereby, the fixing of the workpiece 3 to be processed can be completed.

[0027] In the utility model, the base 31 at the bottom of the workpiece 3 to be processed is placed in the installation cavity 32, and then the installation of the limit plate 2 can be completed through the positioning column 5, the fixing column 6, the threaded column 61 and the limit sleeve 4, so that the workpiece 3 to be processed can be clamped and fixed by the limit plate 2. This fixing method not only makes it convenient for users to position irregular parts, but also has high positioning accuracy, thereby improving the processing quality of parts.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
