[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] In this embodiment, refer to Figure 3 , Figure 4 and Figure 5The system includes a base 1, which is fixed to the machining table of a CNC milling machine to increase support during part processing. A bracket 2 is installed on the base 1 and is fixed to the edge of the base 1 by welding. The bracket 2 is L-shaped and has a limiting groove 8 on its horizontal section. The limiting groove 8 is semi-circular to limit the upper part of the part in the limiting groove 8, which helps to stabilize the part to be processed. It can also limit parts within a certain size range, making it suitable for processing parts of multiple sizes.

[0035] In this embodiment, refer to Figure 4 , Figure 5 and Figure 6 A support plate 3 is also installed on the base 1. The support plate 3 is fixed to the edge of the base 1 by welding, so that the support plate 3 and the bracket 2 are arranged opposite to each other. A clamping mechanism 4 is provided on the support plate 3. The clamping mechanism 4 and the upper end of the bracket 2 are arranged opposite to each other. The clamping mechanism 4 is used to clamp and limit the upper end of the part. The clamping mechanism 4 includes a clamping plate 41 and a limiting screw 42. The clamping plate 41 is fixed to the support plate 3 by fixing screws 7, which facilitates the installation and removal of the clamping plate 41. A screw hole is opened on the clamping plate 41. The limiting screw 42 is threaded through the thread hole and points to the limiting groove 8, so as to securely limit the part in the limiting groove 8 and realize the stabilization of the upper part of the part.

[0036] In this embodiment, refer to Figure 6 The limiting screw 42 is threaded with a limiting nut 6, which strengthens and fixes the limiting screw 42 to the abutment plate 41. At the same time, the limiting nut 6 can also fix and control the limiting screw 42 to a certain length, which is convenient for fixing the upper part of parts of different sizes within a certain range.

[0037] In this embodiment, refer to Figure 7 and Figure 8 The base 1 is also equipped with a reinforcing mechanism 5, which is used to stabilize the lower end of the part. The reinforcing mechanism 5 includes two pressure plates 51, which are respectively installed at two opposite corners on the base 1. The pressure plates 51 are provided with irregularly shaped elongated holes 53. The adjusting screws 52 are inserted into the irregularly shaped elongated holes 53, so that the adjusting screws 52 can move along the length direction of the irregularly shaped elongated holes 53 to adjust the distance between the two pressure plates 51. The two pressure plates 51 work together with the limiting groove 8 and the limiting screw 42 to fix the lower end of parts of different sizes within a certain range. It is suitable for fixing parts of multiple sizes.

[0038] Two threaded holes are provided at two opposite corners on the base 1, so that two adjusting screws 52 are threaded into the two threaded holes respectively. By rotating the adjusting screws 52, the pressure plate 51 is rotated, thereby realizing the adjustment of the position of the pressure plate 51, which facilitates the tightening and loosening of the lower end of the part.

[0039] The working principle of this embodiment is as follows: The part to be processed is placed on the base 1. At this time, the upper end of the part is located in the limiting groove 8, and the lower end of the part is placed between the two pressure plates 51. First, by rotating the adjusting screw 52, ​​the two pressure plates 51 press the bottom edge of the part tightly, so that the part is fixed on the base 1, thus achieving the bottom fixation of the part. Then, by rotating the limiting screw 42, the upper part of the part is pressed against the limiting groove 8. Then, the limiting nut 6 is used to fix the limiting screw 42 to the abutment plate 41, thereby strengthening the tightness of the limiting screw 42 and thus strengthening the tightness of the limiting screw 42 on the part. This facilitates subsequent part processing, achieves double stability for the part, increases the rigidity of the part, reduces the vibration of the part during processing, makes the inner hole size more accurate, reduces the error, improves the overall production efficiency, increases the product qualification rate, and reduces the production cost.
