[0013] Next, we will further explain the tooling for processing the damping piston of a pusher centrifuge described in the present invention with reference to the accompanying drawings.

[0014] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0015] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0016] See Figure 1-2 As shown in , a tooling for processing a damping piston of a pusher centrifuge is characterized by comprising a machine tool clamping base 1, a machine tool clamping block 2 provided on the machine tool clamping base 1, and a locking mechanism provided on the machine tool clamping base 1 for fixing the piston on the machine tool clamping base 1, wherein the locking mechanism comprises a fastening screw 3 installed on the machine tool clamping base 1, a pressure block 4 movably installed on the fastening screw 3, and a nut 5 installed on the fastening screw 3;

[0017] Through the setting of the device, the machine tool clamping block 2 is installed on the machine tool fixture. When drilling the piston, after one side is completed, the machine tool clamping base 1 is driven by the machine tool fixture to rotate and then the other hole is processed. The processing is completed in one clamping, which reduces the positioning error caused by the secondary clamping, ensures the processing accuracy, ensures that the coaxiality of the two damping piston holes meets the design requirements, and avoids the coaxiality error of the two damping piston holes caused by the secondary clamping;

[0018] The setting of the locking mechanism makes it easy to lock and disassemble the piston, and the operation is simple, convenient and fast.

[0019] In one embodiment, it also includes a number of limit blocks 6 arranged on the machine tool clamping base 1 to limit and guide the installation position of the piston.

[0020] The limit blocks 6 are arranged in a triangular shape, and a plurality of limit blocks 6 are symmetrically arranged on the machine tool clamping seat 1;

[0021] By providing a plurality of triangular and symmetrically arranged limit blocks 6, the inclined surfaces on two limit blocks 6 play a guiding and limiting role in the installation of the piston.

[0022] In one embodiment, it also includes a piston positioning block 7 arranged on the machine tool clamping base 1 and a piston positioning groove 8 arranged on the piston and adapted to the piston positioning block 7. Through the setting and matching of the piston positioning block 7 and the piston positioning groove 8, the position of the piston installed on the machine tool clamping base 1 is further limited.

[0023] In one embodiment, it also includes a reinforcing rib 9 arranged on the machine tool clamping base 1 for increasing the strength of the machine tool clamping base 1; the reinforcing rib 9 is arranged to enhance the strength of the machine tool clamping base 1 and prevent the machine tool clamping base 1 from being deformed due to force during the piston processing process.

[0024] When the utility model is in use: first, the piston is installed on the machine tool clamping seat 1 through the inclined surface limit of the limit block 6, and the piston positioning block 7 is placed in the piston positioning groove 8 during installation, thereby completing the position limitation of the piston, and then the pressure block 4 is sleeved on the fastening screw 3 and placed on the upper end surface of the piston, and then the nut 5 is tightened to fasten the piston to the machine tool clamping seat 1; when processing the piston damping hole on the piston, the hole on one side is processed, and after the processing is completed, the machine tool clamping block 2 and the machine tool clamping seat 1 are driven to rotate by the fixture on the machine tool, thereby driving the piston to rotate, and after rotating 180°, the other hole is processed. After the processing is completed, the nut 5 is unscrewed, the pressure block 4 is removed, and the piston can be removed from the machine tool clamping seat 1.
