[0034] Set screw 1: Used to fix the stepped pin 2 to the bottom of the connecting plate body 3;

[0035] Step pin 2: The small end of step pin 2 mates with the hole on the bottom surface of the connecting plate body 3 and is locked together by the set screw 1. The large end of step pin 2 mates with the positioning hole in the middle of the turntable, thereby achieving precise positioning of the turntable and the connecting plate body 1. Because the size of the center positioning hole of different turntable models is different, the large end of this step pin 2 has various specifications. Select the appropriate one according to actual needs when using it.

[0036] The connecting plate body 3 has a positioning hole machined in the center of its bottom surface, which can be matched with the small end of the stepped pin 2; the bottom circumference is machined with various combinations of mounting holes to achieve connection with machining center turntables of various brands and models; the upper surface is machined with positioning pin holes and various threaded holes to achieve precise positioning and clamping of various fixtures (vises, chucks, zero-point positioning, dovetail clamps, and various non-standard fixtures) with the connecting plate body 3, and can also be connected with the connecting plate extension block 5;

[0037] Positioning pin 4: When the connecting plate heightening block 5 is needed, it is used for precise positioning of the connecting plate body 3 and the connecting plate heightening block 5;

[0038] Connecting plate heightening block 5: It is mainly used to install on the connecting plate body 3 when the height of the connecting plate body 3 affects the product processing, and then install the clamp on it. It can also be used independently with a smaller turntable. Correspondingly, its upper and lower surfaces are machined with several positioning pin holes and screw holes.

[0039] Fixing screw 6: Fixes the main body 2 of the connecting plate and the raising block 5 of the connecting plate;

[0040] The operation process is as follows:

[0041] First, determine the model of the step pin 2 according to the size of the fixture for the product being processed and the model of the machine tool turntable. Then, insert the small end of the step pin 2 into the positioning hole in the center of the bottom surface of the connecting plate body 3 and lock it with the set screw 1. Then, fix the assembly of the connecting plate body 3 and the step pin 2 with the positioning screw and T-block, etc., by the large end of the step pin 2 and the center hole of the turntable. (If the connecting plate heightening block 5 is to be used, it can be connected to the connecting plate body 3 by the positioning pin 4 and the fixing screw 6.) Finally, the required fixture can be installed on the end face of the connecting plate body 3 or the end face of the connecting plate heightening block 5. Example
