Embodiment Construction

[0013] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] see figure 1 , figure 2 , The main structure of the present invention includes: threaded seat 1, nut 2, positioning bolt 3, mounting seat 4.

[0015] For the structure of threaded seat 1, see image 3 , Figure 4 : Nut placement slot 5, threaded seat mounting hole 6. Among them, the nut placement groove 5 is used to place the nut 2, the square square groove prevents the placement nut 2 from rotating, and the circular through hole prevents the nut 2 from falling off from the nut placement groove 5; the threaded seat mounting hole 6 is used to fix the threaded seat 1 and the mounting seat 4 with bolts .

[0016] Nut 2 mechanism see Figure 5 , Figure 6 : the nut guide groove 7 cooperates with the positioning bolt guide head 8 to guide the nut 2.

[0017] For positioning bolt 3 mechanism, see Figure 7 .

Abstract

The invention belongs to the technical field of machining and relates to a moving nut mechanism for a clamp. The moving nut mechanism comprises a thread base (1), a nut (2) and a locating bolt (3). A nut placing groove (5) is formed in the thread base (1). The nut (2) is placed in the nut placing groove (5) of the thread base (1). The thread base (1) and a mounting plane are fixed through a bolt. The nut placing groove (5) and the mounting plane form a sealed cavity. A gap is formed between the nut (2) and the nut placing groove (5). One end, close to the mounting plane, of the nut (2) is a nut guiding groove (7) with a chamfer. A locating bolt guiding head (8) is arranged at the end of the locating bolt (3). The locating bolt guiding head (8) and the nut guiding groove (7) are matched. The moving nut mechanism is simple in structure and good in operability, production efficiency is improved, and production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to a traveling nut mechanism for a clamp. Background technique [0002] At present, floating nuts with sheet metal bending structures are often used in aircraft structures to solve the problem of nut tightness in closed areas. Sheet metal bending type floating nut has many advantages, but because of its high cost, unsuitable for repeated loading and unloading and other shortcomings, it is rarely used in fixture tooling. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a traveling nut mechanism for clamps with simple structure, good operability and repeated loading and unloading. [0004] The technical solution of the present invention is: a floating nut mechanism for clamps, characterized in that: the floating nut mechanism includes a threaded seat 1, a nut 2 and a positioning bolt 3; the threaded seat 1 is pr...
