Description
Technical Field
The utility model relates to a chucking device, concretely relates to conical surface chucking device for fixing accelerator disc.
Background
The disc processing technology is mainly applied to the field of accelerators and is mainly characterized by high requirements on coaxiality, verticality, shape tolerance, position tolerance and consistency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a conical surface chucking device for fixing accelerator disc, mainly used accelerator disc is fixed in the course of working. The clamping device can realize rapid clamping and positioning of a workpiece to be machined; the positioning is accurate; the deformation condition of the workpiece in the machining process is effectively prevented.
The conical surface clamping device consists of a mandrel and a locking nut; the two parts are fixed by threaded rotation.
The front end of the mandrel is of an extended conical surface structure, the front end of the conical surface structure is a hollow circular straight table hole, and the circular straight table hole is used for positioning the length of a workpiece to be machined; the rear end of the conical surface structure is provided with threads for connecting with the locking nut;
wherein the threads are double start threads.
Wherein, the rear end of dabber is provided with handheld end.
The locking nut is of a hollow structure, and a conical surface and threads matched with the conical surface structure are arranged inside the locking nut. The locking nut is internally provided with a thread and a conical surface which are matched with the thread and the conical surface of the mandrel, and the locking nut and the mandrel are connected through the thread to enable the conical surfaces of the nut and the mandrel to be matched and clamp a workpiece.
The utility model adopts a conical surface mode for connection and fixation; the mandrel and the locking nut rotate by utilizing threads, so that two corresponding conical surfaces of the mandrel and the locking nut are matched in a fitting manner, and the purpose of clamping a workpiece is achieved.

Drawings
Fig. 1 is a schematic structural view of a conical surface clamping device provided by the present invention;
in the figure: 1. a mandrel; 2. locking the nut; 3. a conical surface structure; 4. a circular truncated cone hole; 5. and (4) threading.
Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Examples
The embodiment provides a conical surface clamping device for fixing an accelerator disk, as shown in fig. 1, the conical surface clamping device is composed of a mandrel 1 and a lock nut 2; the two parts are fixed by threaded rotation.
The front end of the mandrel 1 is an extended conical surface structure 3, the front end of the conical surface structure is a hollow circular straight platform hole 4, and the circular straight platform hole 4 is used for positioning the length of a workpiece to be processed; the rear end of the conical surface structure 4 is provided with a thread 5 for connecting with the locking nut 2;
wherein the thread 5 is a double start thread.
Wherein, the rear end of the mandrel 1 is provided with a handheld end.
The locking nut 2 is of a hollow structure, and a conical surface and threads matched with the conical surface structure 3 are arranged inside the locking nut. The locking nut is internally provided with a thread and a conical surface which are matched with the thread and the conical surface of the mandrel, and the locking nut and the mandrel are connected through the thread to enable the conical surfaces of the nut and the mandrel to be matched and clamp a workpiece.
Wherein, the conical surface angle of the conical surface structure 3 is 5 degrees to 10 degrees. The angle can further provide the adaptive effect of the conical surface, so that the flexibility of the clamping device in the use process is improved; is more convenient for taking and placing in a rotating way.
Wherein, the mandrel 1 is provided with 6 longitudinal seams. When the locking nut 2 is in interference fit with the conical surface of the mandrel 1, a clamping force is applied to the mandrel 1 inwards, so that a workpiece is clamped.
Although the invention has been described in detail in the foregoing by way of general description, specific embodiments and experiments, it will be apparent to those skilled in the art that certain modifications and improvements may be made thereto based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
