For solving the technical problem, the technical proposal of the utility model is that:
the utility model provides an axle type part auxiliary clamping structure, auxiliary clamping structure divide into two parts: a clamping structure 2 and a lock nut 3;
the clamping structure 2 consists of a conical surface, an external thread and a clamping part 4; a plurality of through grooves 5 which are communicated up and down are arranged on the conical surface;
the inner side of the locking nut 3 is provided with a conical surface and an internal thread structure, and the length of the conical surface is determined by the length of the conical surface of the clamping structure 2; the inner thread of the clamping structure is matched with the outer thread of the clamping structure 2; a plurality of decomposers 6 are designed on the end surface of the locking nut 3 for decomposition;
the clamping part 4 is assembled at a central bracket on the machine tool, and the shape of the clamping part is determined by the shape of a clamping end of the machine tool.
The length of the conical surface of the locking nut 3 is 1/2-2/5 of the length of the conical surface of the clamping structure 2. The benefits of the length matching setup are: the greater pressure applied to the conical surface of the clamping structure 2 by the nut causes a sufficient amount of deformation of the conical surface.
The conical surface angle of the locking nut 3 is 10-15 degrees. The angle setting has the advantages of 10-15 degrees: the deformation and shrinkage of the conical surface of the clamping structure 2 are about 0.2mm through calculation, so that the service life of the clamping structure is not influenced too much, and sufficient clamping force can be generated.
Preferably, the through slots 5 on the conical surface of the clamping structure 2 are uniformly arranged. The through groove 5 is used for holding the part 1 tightly.
Preferably, the decomposers 6 are uniformly arranged.
The number of said through slots 5 is greater than or equal to 8, preferably 16.
The number of the decomposition tanks 6 is more than or equal to 3, and preferably, the number is 8.
When the auxiliary clamping structure is assembled, the part 1 is assembled with the clamping structure 2, and the two parts are assembled in a small clearance fit.
The utility model has the advantages that: axle type part length is longer, adopts in the course of working the utility model discloses an axle type part assists clamping structure can guarantee part product machining precision, in the course of working, reduces the radial force that the part received, reduces resonance, eliminates processing deformation. After processing, the precision of the external dimension is less than or equal to 0.02mm, and the position precision is less than or equal to 0.03 mm. The structure has the characteristics of simple structure, convenient assembly and disassembly and improvement of the machining precision and the qualification rate of parts.
