Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a fixed blind rivet of using of digit control machine tool, includes circular head 2, and the top of circular head 2 runs through there is air vent 1, and the bottom welding of circular head 2 has blind rivet neck 3, and the inside of blind rivet neck 3 runs through there is expansion joint 101, and air chamber 102 has been seted up to the bottom of expansion joint 101.

The bottom welding of blind rivet neck 3 has stopper 4, and the bottom welding of stopper 4 has dome 5, and the bottom welding of dome 5 has joint post 6, and the bottom of joint post 6 bonds and has sealing rubber circle 601, and the bottom welding of joint post 6 has fixed screw thread 7, and the bottom of fixed screw thread 7 bonds and has packing ring 8.

In this embodiment, specifically, the vent hole 1 is located at the center of the circular head 2, the vent hole 1 penetrates through the top of the circular head 2, and the vent hole 1 can discharge air from the inside of the blind rivet to balance the internal and external pressures of the blind rivet.

In this embodiment, it is concrete, the expansion joint 101 diameter is a centimeter, and the expansion joint 101 runs through in the inside of circular head 2 and blind rivet neck 3 respectively, and the distance of expansion joint 101 can be when exhausting and deformation, guarantees the hardness of blind rivet neck 3.

In this embodiment, specifically, the space that stopper 4 and dome 5 inside fretwork constitute air chamber 102, and air chamber 102 and expansion joint 101 intercommunication, air chamber 102's effect can be with air balance, the deformation degree of control blind rivet neck 3.

In this embodiment, it is concrete that sealing rubber circle 601 is "circular", and sealing rubber circle 601's diameter and the diameter looks adaptation of joint post 6, sealing rubber circle 601 can control the interlock degree of fixed thread 7 and the inside embedded screw thread of handle of a knife, can reduce the emergence of card silk phenomenon.

In this embodiment, specifically, the gasket 8 is parallel to the sealing rubber ring 601, the gasket 8 is connected to the fixing thread 7 in an adhesive manner, and the gasket 8 can prevent the fixing thread 7 from being excessively engaged with the thread embedded in the handle, so that the possibility of damage to the blind rivet and the handle is reduced.

The working principle is as follows: firstly, a user checks whether the performance of each part of the structure is normal enough, if some parts are found to be abnormal, the parts are maintained or replaced in time, after the performance of each part of the equipment to be checked is normal, the rivet neck 3 is clamped in the special spanner, at the moment, the expansion joint 101 is extruded, air in the air chamber 102 is driven to be discharged from the air vent 1, so that the spacing distance of the expansion joint 101 is reduced, the rivet neck 3 can be clamped into a port of the special spanner more easily, then when the fixed thread 7 is screwed into the embedded thread in the cutter handle, the clamping column 6 moves downwards along with the downward movement of the fixed thread 7, meanwhile, the sealing rubber ring 601 at the bottom of the clamping column 6 generates friction with the clamping hole in the inner wall of the cutter handle by controlling the clamping hole, so as to control the meshing degree of the embedded thread in the fixed thread 7 and the cutter handle, and further to ensure that the fixed, when the utility model discloses when advancing the inside certain degree of depth of handle of a knife soon, dome 5 can closely laminate with the handle of a knife top, and packing ring 8 can slow down the sliding speed of the fixed thread 7 of bottom this moment, avoids fixed thread 7 and the excessive interlock of embedded screw thread, and is good at the installation the utility model discloses afterwards, the epaxial bayonet socket of lathe owner can be fixed circular head 2 inside the lathe main shaft to block stopper 4, make the tool bit begin normal work, just so accomplished the utility model discloses a use flow.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
