Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to an anti-swing tooling for carbon screw processing. Background Technology

[0002] Carbon / carbon composite materials are made by laminating carbon fiber mesh and finely woven carbon fiber products into preforms, followed by densification through chemical vapor deposition and / or impregnation. They possess excellent properties such as high temperature resistance, high specific strength, high specific modulus, ablation resistance, low coefficient of thermal expansion, and thermal shock resistance, making them particularly suitable for high-temperature structural components. They are an ideal material to replace graphite fasteners in high-temperature environments. Using carbon / carbon composite screws instead of graphite screws can effectively extend service life and ensure stable and reliable operation of components under high-temperature conditions.

[0003] In the manufacturing process of carbon carbon screws, thread machining is a crucial step. However, the following problems commonly exist in the current thread machining production process:

[0004] During thread cutting, due to the cutting force, the carbon carbon screw is prone to deviation and swaying while rotating. This causes the ellipticity of the thread on the screw wall to increase, and the thread depth to vary in the circumferential direction, ultimately leading to the carbon carbon screw becoming unqualified. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-swing tooling for carbon carbon screw processing, which overcomes the deficiencies of existing technologies and effectively solves the problem that carbon carbon screws are prone to offset and swing while rotating, which causes the thread ellipticity of the screw wall to increase and the thread depth to be uneven in the circumferential direction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tooling for preventing the swaying of carbon screws includes a base. A lead screw is rotatably connected to the inner walls of both ends of the base, and a movable block is screwed to the wall of the lead screw. A clamping mechanism is connected to the top of the movable block. The clamping mechanism includes a U-shaped frame, a handle screw screwed to the top of the outer wall of one end of the U-shaped frame, a conical rod rotatably connected to one end of the handle screw, and a fastening assembly rotatably connected to the top of the outer wall of the other end of the U-shaped frame. The fastening assembly includes a circular block, a rotating shaft welded and fixed to the back of the circular block, a connecting frame welded and fixed at equal intervals to the annular outer wall of the circular block, an adjusting block slidably connected within the connecting frame, a first adjusting screw rotatably connected to the outer wall of one end of the adjusting block, a second adjusting screw and a guide rod respectively penetrating and connected to both ends of the outer wall of one side of the adjusting block, and a clamping block connected to the second adjusting screw and the guide rod.

[0008] By abutting the large end of the carbon screw with the round block, rotating the handle screw causes the conical rod to abut the diameter end of the carbon screw, clamping and fixing the carbon screw between the round block and the conical rod. Then, by rotating the first adjusting screw in sequence, the first adjusting screw moves spirally within the connecting frame, causing the adjusting block to move towards the position of the carbon screw within the connecting frame, so that the clamping block abuts the diameter of the carbon screw. Then, by rotating the second adjusting screw in sequence, the clamping block moves along the guide rod, causing the clamping block to abut the large end of the carbon screw, clamping and fixing the carbon screw between the round block and the clamping block.

[0009] Preferably, a first servo motor is fixedly mounted on the outer wall of one end of the base, and the output shaft of the first servo motor is connected and fixed to one end of the lead screw through a coupling.

[0010] The first servo motor drives the lead screw to rotate.

[0011] Preferably, the movable block and the base are in a sliding fit, and the top of the movable block is welded and fixed to the bottom of the U-shaped frame.

[0012] The rotating lead screw drives the screwed movable block to move along the base, and the movable block drives the clamping mechanism to move back and forth.

[0013] Preferably, a second servo motor is installed and fixed on the top of the outer wall of the other end of the U-shaped frame, and the output shaft of the second servo motor is connected and fixed to one end of the rotating shaft through a coupling.

[0014] The second servo motor drives the rotating shaft to rotate, and the rotating shaft drives the entire clamping assembly to rotate.

[0015] Preferably, the outer wall of the connecting frame at the end away from the circular block is provided with a screw hole, and the screw hole forms a threaded engagement with the first adjusting screw.

[0016] By rotating the first adjusting screw, the first adjusting screw moves spirally within the connecting frame, thereby adjusting the position of the adjusting block within the connecting frame.

[0017] Preferably, the second adjusting screw is screwed to the adjusting block, and the guide rod is slidably connected to the adjusting block.

[0018] Both the second adjusting screw and the guide rod can move within the adjusting block.

[0019] Preferably, the second adjusting screw is rotatably connected to the clamping block, and the guide rod is welded and fixed to the clamping block.

[0020] Rotating the second adjusting screw will cause the clamping block to move along the guide rod.

[0021] The beneficial effects of this utility model are as follows:

[0022] By clamping and fixing the carbon carbon screw between the round block and the conical rod, and then rotating the first adjusting screw in sequence to make the clamping block abut against the diameter of the carbon carbon screw, and then rotating the second adjusting screw in sequence to move the clamping block along the guide rod to make the clamping block abut against the large end of the carbon carbon screw, the carbon carbon screw is clamped and fixed between the round block and the clamping block. This effectively solves the problem in the prior art that the carbon carbon screw is prone to deflection and swinging while rotating, which causes the thread ellipticity of the screw wall to increase and the thread depth to be uneven in the circumferential direction.

[0031] A first servo motor 4 is fixedly mounted on the outer wall of one end of the base 1.
