[0002] With the continuous progress of industrialization, there are now many parts with smaller and smaller shapes, higher and higher requirements for the roughness of structural holes, and higher and higher accuracy requirements for structural dimension processing. For example Figure 1 For the described part, its top end is a large opening, the bottom end is a small opening, and there is a flange around the outer periphery of the top end. The volume of this part is small, and the abrasive flow processing is difficult. Therefore, an abrasive flow clamping tooling is designed now, which can clamp multiple parts at one time, has high processing efficiency, and has good protection effect on the parts, ensuring the processing quality of the parts. Summary of the Utility Model

[0003] In view of the above defects or deficiencies in the prior art, it is expected to provide an abrasive flow clamping tooling that can clamp multiple parts at one time, has high processing efficiency, and has good protection effect on the parts, ensuring the processing quality of the parts.

[0004] An abrasive flow clamping tooling provided by the utility model includes:

[0005] A lower base on which a plurality of vertical lower abrasive through holes are evenly distributed, and a positioning installation groove is opened at the top end of the lower abrasive through hole;

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0029] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and embodiments.

[0030] Please refer to Figures 1 to 5 , an embodiment of the present utility model provides an abrasive flow clamping tooling, including:

[0031] A lower base 1, on which a plurality of vertical lower abrasive through holes 11 are evenly distributed, and a positioning installation groove 12 is opened at the top end of the lower abrasive through hole 11;

[0032] An upper base 2, arranged on the top of the lower base 1, fixedly connected to the lower base 1 through at least two positioning bolts 21, and an upper abrasive channel 22 corresponding to the lower abrasive through hole 11 one by one is opened on the upper base 2, and the inner diameter of the upper abrasive channel 22 is the same as the inner diameter of one end of the part 4 close to the upper abrasive channel 22.

[0033] In this embodiment, when deburring the inner hole of the part 4, first place the part 4 with the large mouth 41 facing up and the small mouth 42 facing down at the top end of the lower abrasive through hole 11, and the flange 43 of the part 4 is embedded in the positioning installation groove 12; after the installation of the part 4 is completed one by one, press the upper base 2 on the lower base 1 and fix the two through the positioning bolts 21. Then install the clamping tooling on the abrasive flow equipment for deburring treatment. The abrasives flow into through the respective upper abrasive channels 22, pass through the part 4 through the large mouth 41 and the small mouth 42, and then enter the lower abrasive through hole 11, and then return to the abrasive flow equipment. The deburring treatment of multiple parts 4 is completed at one time, effectively improving the work efficiency.

[0034] During the deburring process, the upper base 2 covers the end face of the flange 43, so that the abrasives can only pass through the inner hole of the part 4 to complete the grinding treatment, and will not damage the end face of the part 4, ensuring the processing quality of the part 4.

[0035] In a preferred embodiment, as Figure 2 shown, both the lower base 1 and the upper base 2 are circular, which is convenient for assembling them onto the abrasive flow equipment.

[0036] In a preferred embodiment, as Figure 2As shown, 5 - 8 lower abrasive through - holes 11 are evenly distributed on the outer periphery of the lower base 1 at its center. The processing of 5 - 8 parts 4 is completed at one time. If the number of parts processed at one time is too large, the grinding effect will decline; if the number of parts processed at one time is too small, the processing efficiency is low.

[0037] In a preferred embodiment, as Figure 2 and Figure 3 shown, a circular positioning boss 13 protruding downward is provided on the bottom surface of the lower base 1, which is convenient for the clamping tooling to be accurately docked with the material cylinder of the abrasive flow equipment.

[0038] In a preferred embodiment, as Figure 2 and Figure 5 shown, a number of positioning pin columns 3 are evenly distributed along the circumferential direction on the top - surface edge of the upper base 2. The bottom end of the positioning pin column 3 is fixedly connected to the upper base 2 through a fixing bolt 31. The clamping tooling is positioned and installed in the abrasive flow equipment through the positioning pin columns 3 to ensure the stability of its installation and the accuracy of the installation position.

[0039] In a preferred embodiment, as Figure 2 and Figure 3 shown, lower positioning holes 14 are symmetrically opened on both sides of the lower base 1; upper positioning holes 23 corresponding to the lower positioning holes 14 are opened on both sides of the upper base 2. When fixing the upper base 2 and the lower base 1 through the positioning bolt 21, first align the upper positioning hole 23 with the lower positioning hole 14, and then the positioning bolt 21 can be accurately inserted and tightened, which improves the convenience of fixing the upper base 2 and the lower base 1.
