Description
Technical Field
The utility model relates to a manufacturing and processing technical field of aviation spare part, concretely relates to blade mould multi freedom plane closing device.
Background
The plane closing device is an indispensable part in manufacturing processes such as machining, welding, assembly, detection, and the mode commonly used in the trade is that practical bolt compresses tightly at present, but when the position that the part need compress tightly was the inclined plane, adopts conventional bolt to compress tightly, and the contact surface then can become a point, and when the contact surface diminishes, will grow to the pressure of part, can lead to the part to warp, scrap when serious. Aiming at the existing problems, it is very important to design a plane pressing device with simple structure, good universality and convenient disassembly and assembly.
To sum up, the utility model designs a blade mould multi freedom plane closing device.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a not enough to exist on the prior art, the utility model aims at providing a blade mould multi freedom plane closing device, structural design is reasonable, can compress tightly the plane fast, compress tightly the inclined plane that has certain angle of inclination fast to guarantee that the contact surface is the plane all the time in the certain limit, convenient to use is reliable, and the practicality is strong.
In order to achieve the above purpose, the present invention is realized by the following technical solution: a multi-degree-of-freedom plane pressing device of a blade die comprises a movable nut and a pressing bolt, wherein the pressing bolt is provided with a ball head, a first external thread, a second external thread and a rotating disc, and the movable nut is provided with a pressing surface, a spherical groove and an internal thread; the movable nut and the pressing bolt are connected through a first external thread and an internal thread, the ball head is in contact with the spherical groove, the second thread is connected with an external auxiliary device, the pressing surface is in contact with the surface of a workpiece, and the rotating disc is arranged at the outer end of the pressing bolt.
Preferably, the second external thread is provided at the middle of the pressing bolt.

Preferably, the internal thread is arranged in the spherical groove.
The utility model has the advantages that: the utility model has the advantages of reasonable design, the commonality is good, and it is convenient to dismantle, can compress tightly the plane fast, compress tightly the inclined plane that has certain angle of inclination fast to guarantee that the contact surface is the plane all the time in the certain limit, it is convenient to use, and the practicality is strong.
Drawings
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the working state of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: a multi-degree-of-freedom plane pressing device of a blade die comprises a movable nut and a pressing bolt, wherein the pressing bolt is provided with a ball head 7, a first external thread 6, a second external thread 5 and a rotating disc 4, and the movable nut is provided with a pressing surface 1, a spherical groove 2 and an internal thread 3; the movable nut and the pressing bolt are connected through a first external thread 6 and an internal thread 3, the ball head 7 is in contact with the spherical groove 2, the second thread 5 is connected with an external auxiliary device, the pressing surface 1 is in surface contact with a workpiece 8, and the rotating disc 4 is arranged at the outer end of the pressing bolt.
It is noted that said second external thread 5 is provided in the middle of the hold-down bolt.
It is noted that the rotating disc 4 is arranged perpendicular to the screw of the hold-down bolt.
Furthermore, said internal thread 3 is arranged in the spherical recess 2.
This embodiment's a blade mould multi freedom plane closing device, pass through internal thread 3 with clamp bolt and be connected with first external screw thread 6 with movable nut, after ball 7 and the spherical recess 2 contact of movable nut of clamp bolt, internal thread 3 no longer contacts with first external screw thread 6, at this moment movable nut can be at the certain internal rotation of within range, screw thread 5 is connected with outside auxiliary device, pressing surface 1 and 8 surface contact of work piece, make clamp bolt downstream through screwing up the rolling disc, reach the mesh that compresses tightly. When the contact surface inclines, the movable nut can automatically adjust the angle to be parallel to the contact surface, and the contact area is guaranteed to be maximized all the time.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
