In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] like Figures 1 to 5 As shown, this embodiment provides a clamping tool for clamping the bottom surface 101 and the side surface 102 of an annular thin-walled part (hereinafter referred to as the part) to facilitate processing of the side surface 102 of the part 100.

[0039] In some embodiments, the clamping tool includes a base 1, a pressing member 2, and an auxiliary member 3. The base 1 is used to place the part 100; the pressing member 2 is arranged on the base 1, and the pressing member 2 is used to abut against the bottom surface 101 of the part 100; the auxiliary member 3 is arranged on the base 1, and one side of the auxiliary member 3 is connected to the base 1, and the other side is used to connect to the side surface 102 of the part 100. Specifically, since the part 100 is an annular part, in order to facilitate the placement of the part 100 on the base 1, the base 1 is a circular seat.

[0040] The arrangement of the clamping member 2 enables the part 100 to be placed on the base 1 more stably; the auxiliary member 3 is arranged on the base 1, one side of the auxiliary member 3 is connected to the base 1, and the other side is used to connect to the side 102 of the part 100, and the auxiliary member 3 supports the side 102 of the part 100. By arranging the clamping member 2 and the auxiliary member 3, the stability of the clamping of the part 100 is improved, and when the tool acts on the part 100, the part 100 will not vibrate, and the tool will be more accurately docked when acting on the cutting point of the part 100, thereby improving the processing qualification rate of the part 100.

[0041] Furthermore, if Figure 1 and Figure 2As shown, in order to place the part 100 more stably on the base 1, a plurality of pressing members 2 are provided, and the plurality of pressing members 2 are evenly distributed on the base 1 along the circumference of the base 1. Specifically, the material of the pressing member 2 can be steel. In this embodiment, six pressing members 2 are provided, and the six pressing members 2 are evenly distributed on the base 1 along the circumference of the base 1, so that the bottom surface 101 of the part 100 is stably pressed on the base 1. In other embodiments, the number of pressing members 2 can also be 4, 5, 7 or 8, but it is not limited thereto.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in order to fix the clamping piece 2 to the base 1 so that the clamping piece 2 can clamp the bottom surface 101 of the part 100, the clamping tool also includes a first connecting piece, and the clamping piece 2 includes an abutting portion and a mounting portion. The abutting portion is used to abut the bottom surface 101 of the part 100; the mounting portion is used for the first connecting piece to pass through so as to fix the clamping piece 2 to the base 1.

[0043] Specifically, the first connecting member includes a screw 41 and a nut 42. The pressing member 2 is provided with a connecting hole 21, and the base 1 is provided with a through hole 11. The screw 41 can pass through the connecting hole 21 and the through hole 11 in sequence, and the pressing member 2 is fixed to the base 1 through the nut 42. Specifically, the nut 42 is a flange nut 42, and the contact area between the flange nut 42 and the pressing member 2 is larger, ensuring the firmness of the connection.

[0044] Furthermore, the connection hole 21 includes a waist hole, which extends in the radial direction of the base 1. The waist hole is provided on the clamping member 2 so that the connection position between the clamping member 2 and the base 1 can be adjusted, so that the clamping member 2 can be applied to parts 100 with different radii, thereby making the clamping tooling more applicable.

[0045] like Figure 1 and Figure 2 As shown, in order to make the side 102 of the part 100 more stable during processing, a plurality of auxiliary parts 3 are provided, and the plurality of auxiliary parts 3 are evenly distributed on the base 1 along the circumference of the base 1. Specifically, the material of the auxiliary part 3 can be aluminum, and the hardness of the aluminum material is relatively low, so that the auxiliary part 3 will not scratch the part 100 when it contacts the part 100. In addition, the price of aluminum is relatively low, which is conducive to cost saving. In this embodiment, six auxiliary parts 3 are provided, and the six auxiliary parts 3 are evenly distributed on the base 1 along the circumference of the base 1, so that the side 102 of the part 100 is stably supported. In other embodiments, the number of auxiliary parts 3 can also be 4, 5, 7 or 8, but it is not limited thereto.

[0046] like Figure 1 , Figure 2 and Figure 5As shown, in order to facilitate the connection between the auxiliary part 3 and the base 1 and the part 100, the auxiliary part 3 includes a first connection portion 31 and a second connection portion 32, and the first connection portion 31 is fixedly connected to the base 1; the side 102 of the part 100 has a disengagement portion 103, and the second connection portion 32 is fixedly connected to the disengagement portion 103. Specifically, the auxiliary part 3 and the part 100, and the auxiliary part 3 and the base 1 are fixed by bonding. It is worth noting that before processing the side 102 of the part 100, the blank needs to be processed into a semi-finished product of the annular part 100. Due to process reasons, the disengagement portion 103 will be formed on the part 100 after processing, but the disengagement portion 103 does not belong to the structural features of the finished product of the part 100. Therefore, after the processing of the side 102 of the part 100 is completed, the support portion needs to be cut off. The auxiliary member 3 is fixed to the side surface 102 of the component 100 by bonding with the outgoing portion 103. Therefore, after the outgoing portion 103 is cut, no residual adhesive will remain on the side surface 102 of the component 100 to damage the appearance of the component 100. When the auxiliary member 3 needs to be separated from the base 1, a debonding agent can be used to separate the auxiliary member 3 from the base 1.

[0047] like Figures 1 to 3 As shown, in order to place the base 1 stably on the workbench, the clamping tool further includes a support member 5 , which is connected to the base 1 for supporting the base 1 .

[0048] Specifically, the clamping tool also includes a second connecting member 6, the base 1 is provided with a first mounting hole 12, the support member 5 is provided with a second mounting hole, and the second connecting member 6 can pass through the first mounting hole 12 and the second mounting hole in sequence to connect the base 1 and the support member 5.

[0049] The first mounting hole 12 includes a countersunk hole, and the countersunk hole includes a first hole 121 and a second hole 122. The second connecting member 6 is a bolt. The length and width of the first hole 121 are both greater than the head diameter of the bolt, the length of the second hole 122 is greater than the head diameter of the bolt, the width of the second hole 122 is less than the head diameter of the bolt, and the bottom surface 101 can cover the countersunk hole. The length and width of the first hole 121 are both greater than the head diameter of the bolt, so that the head of the bolt can be placed in the countersunk hole, the width of the second hole 122 is less than the head diameter of the bolt, so that the head of the bolt can be stuck in the countersunk hole, the length of the second hole 122 is greater than the head diameter of the bolt, so that part of the countersunk hole can be exposed. At the same time, the bottom surface 101 of the part 100 can cover part of the countersunk hole so that after the part 100 is processed, the part 100 will not be completely adsorbed on the base 1, which is convenient for taking the processed part 100.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
