The support seat 100 has multiple bearing holes with precise structures, and the two support seats 100 have the same shape. During processing, it is first processed separately and then combined. That is, after each support seat 100 is processed individually, they are combined for further processing. In particular, a high machining accuracy needs to be ensured for the right-angle part between the bottom plate part 110 and the column part 120 of the support seat 100. The right-angle part between the column part 120 and the bottom plate part 110 means that the circular curved surface 1201 of the column part 120 is highly perpendicular to the bottom plate surface 1101 of the bottom plate part 110.

[0004] Currently, the processing of the support seat 100 mainly adopts the milling method. However, milling requires customized special tools. Affected by the material, the cutting edge is prone to wear during the processing. In order to ensure the right angle, the tool needs to be changed frequently. The milling cutter is expensive and the processing cost is high. The structure of the support seat 100 is special. In order to ensure the processing quality during processing, four-axis or five-axis machine tools are required, resulting in high costs, etc.

[0005] Therefore, there is an urgent need to provide a support seat clamping device. By using this support seat clamping device, the support seat can be generated through turning processing, with high processing accuracy and low processing cost. Summary of the Utility Model

The clamping assembly 2 has an abutting portion, and the abutting portion is used to abut against one side of the support base 100 facing the clamping slot 12, so that the bottom plate portion 110 is positioned in the positioning slot 11. Explanatorily, the rotating carrier of the turning equipment is an existing processing equipment and will not be elaborated specifically.

[0046] During processing, the bottom plate portion 110 of the support base 100 can be inserted into the positioning slot 11, then the clamping assembly 2 is inserted into the clamping slot 12, and the abutting portion is used to abut against one side of the support base 100 facing the clamping slot 12, so that the bottom plate portion 110 is positioned in the positioning slot 11. The base 1 is fixed to the rotating carrier of the turning equipment. The rotating carrier of the turning equipment drives the support base clamping device and the positioned and clamped support base 100 to rotate, and then the support base 100 can be turned. Since the rotating carrier of the turning equipment can directly form the circular curved surface 1201 of the support base 100 by turning with a tool when rotating, and then retracting the tool along the radial direction of the circular curved surface 1201, the bottom plate surface 1101 perpendicular to the circular curved surface 1201 on the bottom plate portion 110 can be machined, thereby realizing high-precision machining of the right-angle part between the cylindrical portion 120 and the bottom plate portion 110 of the support base 100.

[0048] Referring to Figure 2-3 , in some embodiments, the width dimension of the positioning slot 11 is configured to be smaller than the width dimension of the bottom plate portion 110, so that the bottom plate portion 110 extends into the clamping slot 12 along the width direction Y; preferably, the difference can be 2 mm or 1 mm or 3 mm, which can enable the clamping assembly 2 to clamp the bottom plate portion 110, and then firmly fix the support base 100 in the positioning slot 11.

[0049] Referring to Figure 2-3, in some embodiments, a first relief arc groove 13 is provided at the corner position of at least one positioning slot 11. The first relief arc groove 13 communicates with the positioning slot 11 and is configured to avoid the corners of the bottom plate portion 110, thereby facilitating the insertion of the bottom plate portion 110 into the positioning slot 11 and avoiding the corners and edges of the bottom plate portion 110. A second relief arc groove 14 is provided at the corner position of at least one clamping slot 12. The second relief arc groove 14 communicates with the clamping slot 12 and is configured to avoid the corners of the clamping assembly 2, thereby facilitating the insertion of the clamping assembly 2 into the clamping slot 12.

The first right-angle plate 21 includes a first flat plate 211 and a second flat plate 212 fixedly connected to the first flat plate 211, and the first flat plate 211 and the second flat plate 212 are perpendicular to each other; the second right-angle plate 22 includes a third flat plate 221 and a fourth flat plate 222 fixedly connected to the third flat plate 221, and the third flat plate 221 and the fourth flat plate 222 are perpendicular to each other; wherein, the first right-angle plate 21 and the second right-angle plate 22 are spliced together to form a square tubular structure that can be fixed in the clamping slot 12, with a simple structure and can be assembled separately, that is, first insert the first right-angle plate 21, and then insert the second right-angle plate 22.

[0051] Furthermore, reference Figure 2-3 , in some embodiments, the first flat plate 211 faces the third flat plate 221, and a plurality of first through holes 2111 are provided in the first flat plate 211, and second through holes 2211 corresponding to each of the first through holes 2111 are provided in the third flat plate 221; wherein, the support base clamping device further includes a plurality of fastening bolts (not shown in the figure), and the fastening bolts pass through the first through holes 2111 and the first through holes 2111 to fix the first right-angle plate 21 and the second right-angle plate 22 in the clamping slot 12, thereby ensuring the firm fixation of the first right-angle plate 21 and the second right-angle plate 22.

[0052] Reference Figure 2-3, in some embodiments, one end of the first flat plate 211 has a first abutting bevel 2112, and one end of the fourth flat plate 222 has a second abutting bevel 2221.

The abutting forces in the two directions extend along the wall direction of the square tubular structure, and the abutting forces in the two directions are perpendicular to each other. Similarly, the third abutting bevel 2121 and the fourth abutting bevel 2212 abut, and it is also the same structure, which will not be elaborated here.

[0053] Reference Figure 2-3 , in some embodiments, the depth of the positioning slot 11 is less than the depth of the clamping slot 12, which is beneficial for the clamping assembly 2 to abut against the bottom plate portion 110 of the support seat 100 comprehensively along the depth direction, and the clamping and fixing is more stable.

[0054] In some embodiments, reference Figure 2-3 , the base 1 includes a carrier portion 15 and a shaft portion 16.
