Abstract
The utility model pertains to tool technology and relates to a device for fast assembling a threaded bush. The device consists of a thread section, a washer, a substrate, a transition section and an operation section, wherein the thread section is arranged at one end of the device; the substrate is arranged between the thread section and the transition section; the diameter of the substrate is larger than that of the operation section, and the diameter of the transition section is the same as that of the thread section; the operation section is arranged at the other end of the device; and the washer is sleeve-jointed on the thread section. The cross section of the operation section is a tetrahedrold or a hexahedron. The materials of the device can be obtained easily and conveniently, and the assembly of the threaded bush can be realized fast by utilizing the device and a torque wrench. Due to the arrangement of the washer on the device, the treaded bush is not damaged; and the thread section of the device is screwed in the inner thread of the threaded bush, therefore, the thread is under the action of torque, and the threaded bush can not be driven when the device is screwed out; and as for the threaded bushes with different specifications, only the size of the thread of the device needs to be correspondingly changed.
Description
Technical field
The utility model belongs to tool technique, relates to a kind of device of quick assembling screw-thread bush.
Background technology
At present, when screw-thread bush is installed, all be to adopt spanner directly to pull screw-thread bush, the screw-thread bush force side is the end face of thick 2mm, make side's wearing and tearing in the spanner when directly pulling easily with spanner, and spanner damages the external screw thread of screw-thread bush easily, thereby the outer face of screw-thread bush easily produces burr influence and the assembly relation that is mounted part, and sealing effectiveness does not reach requirement.
Summary of the invention
The purpose of this utility model provides a kind of screw-thread bush end face that do not damage, and better satisfies and the device that is mounted a kind of quick assembling screw-thread bush of part sealing effectiveness.Technical solution of the present utility model is, device is made up of thread segment, packing ring, matrix, changeover portion and lever piece, and thread segment places an end of device, is matrix between thread segment and the changeover portion, the diameter of matrix is greater than the diameter of changeover portion, and changeover portion is identical with the diameter of thread segment; Lever piece places the other end of device; Gasket sleeve is connected on the thread segment.The cross section of lever piece is tetrahedron or hexahedron.Advantage that the utlity model has and beneficial effect, the utility model is drawn materials easy, utilizes the useful novel and torque spanner of this reality just can realize assembling screw-thread bush fast.Owing on device, be provided with packing ring, make screw-thread bush injury-free, because the thread segment of device is to screw on the internal thread of screw-thread bush, therefore, screw thread is under moment loading, device can not drive screw-thread bush when screwing out, and for the screw-thread bush of different size, only needs the thread size of corresponding modifier to get final product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Device is made up of thread segment 1, packing ring 5, matrix 4, changeover portion 2 and lever piece 3, and thread segment 1 places an end of device, is matrix 4 between thread segment 1 and the changeover portion 2, and the diameter of matrix 4 is greater than the diameter of changeover portion 2, and changeover portion 2 is identical with the diameter of thread segment 1; Lever piece 3 places the other end of device; Packing ring 5 is socketed on the thread segment 1.The cross section of lever piece 3 is tetrahedron or hexahedron.
The inside and outside circle of screw-thread bush is screw thread, and installing an end is the internal thread connection of thread segment 1 and screw-thread bush; The other end of device is a lever piece 3, and the cross section of lever piece 3 is tetrahedron or hexahedron, and lever piece 3 and torque spanner connect; Packing ring 5 is socketed on the thread segment 1, and packing ring 5 is an aluminum packing ring, and packing ring 5 can protect screw thread injury-free.
The utility model cooperates torque spanner to use together, can fast screw-thread bush be packed into, because computing formula according to moment, thread segment 1 diameter of device is less than the external diameter of screw-thread bush, the moment of the required device of back-outing is less than the moment of threaded together lining, when the assembling screw-thread bush, on the external screw thread of screw-thread bush, scribble fastening glue, therefore can guarantee when extractor, can not drive screw-thread bush.
Assembling process concrete operations flow process is as follows:
The first, thread segment 1 one ends with device are screwed in the screw-thread bush;
The second, the screw-thread bush external screw thread is coated LOCTITE 277 fastening glue;
Three, torque spanner is adjusted to required moment, is inserted on band four directions on the device or six sides' the lever piece 3;
Four, screw-thread bush is screwed into part;
Five, the torque reaction spanner withdraws from device from screw-thread bush.
