Abstract

The invention provides a quickly detachable nut. The quickly detachable nut is arranged on a metal machining tool, and is matched with a T-head bolt to clamp a workpiece. According to the quickly detachable nut provided by the invention, an inclined hole is machined in the nut, the inner diameter of the inclined hole is larger than the diameter of an outer circle of the T-head bolt, a centerline of the inclined hole and that of the clamping nut form a certain included angle, the nut can be detached and taken out directly by being unscrewed for a short distance and moved to a position where the centerline of the T-head bolt is superposed with that of the inclined hole along the direction of the inclined hole, without unscrewing the whole nut out of the T-head bolt; and both time and labor are saved during the operation.

Description

A kind of fast quick-detach nut

Affiliated technical field

The clamp nut that the present invention relates to a kind of clamping work pieces on metal working machine tool and use, the fast quick-detach of especially a kind of ability, clamp nut very easy to use.

Background technology

At present, the clamping work pieces nut on the known metal working machine tool all is a plain nut, promptly on the whole length of nut inner hole, all is distributed with screw thread; And the thickness of the workpiece that lathe will be processed is often not of uniform size; In order to satisfy the clamping of all thickness workpiece, the T connector bolt that generally cooperates with binding nut all selects length long, to satisfy the clamping of maximum ga(u)ge workpiece; Like this when the smaller workpiece of grip thickness; The length that binding nut need be screwed into the T connector bolt is just very long, when clamping and dismantling, loses time very much, has influenced the raising of production efficiency.

Summary of the invention

The deficiency that in use exists for the nut that overcomes clamping work pieces on the existing metal working machine tool; The present invention provides a kind of fast quick-detach nut, and by an inclined hole, the internal diameter size of inclined hole is greater than the outside diameter size of T connector bolt in endoporus processing for this nut; The center line of inclined hole and the center line of binding nut form an angle; In dismounting during nut, as long as with the nut a bit of distance of back-outing, again with the nut position that direction is pulled T connector bolt center line and inclined hole central lines along the hole; Just can nut directly be taken out, operating process is very time saving and energy saving.

The technical solution adopted for the present invention to solve the technical problems is

On binding nut, two crossing center lines are arranged, a center line is vertical with the clamping end face of nut, and this center line is as the center of nut inner thread; Another center line becomes certain included angle a with the center line of nut inner thread; This center line is as the center of quick removal hole; Because the diameter of removal hole is greater than the outside diameter size of T connector bolt fast; So when nut when inner rotary makes nut can swing an angle a away from the distance of surface of the work at least, just there is no need nut to be screwed out, as long as nut is pulled the center line that makes quick removal hole and the central lines of T connector bolt always; Just become the big matched in clearance of hole with axle by threaded engagement between nut and the T connector bolt, nut just can be taken out very easily fast.

The invention has the beneficial effects as follows

Simple in structure, easily manufactured, with low cost, need not use cushion block just can easily clamp or dismantle the workpiece of any thickness, operating process is time saving and energy saving, has improved production efficiency, has reduced operative employee's labour intensity.

Description of drawings,

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Accompanying drawing is plan view of the present invention.

In the accompanying drawing

1.T type hook bolt; 2. fast quick-detach nut; 3. workpiece; 4. the work top of lathe;

The specific embodiment

In the T type groove of the work top (4) of metal working machine tool, T connector bolt (1) is housed, the bolt of T connector bolt (1) partly stretches out T type groove; The screw portion that T connector bolt (1) is passed in hole on the workpiece to be processed (3) with; The screw thread of fast quick-detach nut (2) T connector bolt (1) is wanted to screw, and leans on the clamping of screw thread pair to stand on the work top that is fixed on lathe (4) that workpiece (3) is firm, on fast quick-detach nut (2); There are a center line and nut center line to intersect and the through hole of a that forms an angle; When dismounting nut (2), need nut (2) all not screwed out the thread head of T connector bolt (1) through screw thread, only need earlier nut (2) outwards to be screwed out; Treat to have between fast quick-detach nut (2) and the workpiece (3) to be processed a minimum can guarantee nut (2) deflection angle a apart from the time; Can stop nut (2) is outwards screwed out, and nut (2) deflection is made through hole and the bolt central lines of nut (2), so fast quick-detach nut (2) is just partly taken out from the bolt of T connector bolt (1) through through hole very easily; Time saving and energy saving, very convenient.

Claims

1. fast quick-detach nut; Through with metal working machine tool on the T connector bolt cooperate to come clamping work pieces, it is characterized in that: need nut all not screwed out the T connector bolt when dismantling this nut, as long as nut is screwed out a bit of distance; The deflection certain angle just can directly be taken out nut again.

2. fast quick-detach nut according to claim 1; It is characterized in that: on this dismounting nut except screwed hole is arranged; The via hole that also has the center line of a center line and nut to form an angle, quick unloading process is directly to take out nut through the matched in clearance of T connector bolt and via hole to realize.
