Abstract

The utility model discloses a built-in door roller lead screw limiting device, which aims to resolve problems that the existing built-in door roller lead screw limiting device is relatively difficult in travel adjustment, relatively poor in positioning precision and the like. One end of a lead screw (5) is connected with one end of a flexible shaft (1), the other end of the flexible shaft (1) is connected with a speed reducer, and a flange capable of being fixedly connected with an adapter sleeve at the end of the flexible shaft (1) is arranged at the end of the lead screw (5) outside a fixing fame (3). Therefore, the built-in door roller lead screw limiting device has the advantages of convenient travel adjustment, accurate positioning and the like.

Description

Built-in door-rolling machine screw mandrel stopping means
Affiliated technical field the utility model relates to a kind of door-rolling machine, especially relates to a kind of built-in door-rolling machine screw mandrel stopping means of being made up of fixed mount, travel switch, screw mandrel, feed screw nut, adjusting nut and hold-down screw.
Background technology is present, a kind of so built-in door-rolling machine screw mandrel stopping means is disclosed on the market, its design feature is: by fixed mount, travel switch, screw mandrel, the feed screw nut, adjusting nut and hold-down screw are formed, the two ends of screw mandrel are arranged in the fixed mount by axle sleeve, screw mandrel is provided with feed screw nut and adjusting nut, be provided with hold-down screw at the feed screw nut top, travel switch is installed in the chute both sides in the fixed mount, after adopting this structure, motor reel drives the screw mandrel rotation by gear drive, thereby drive the feed screw nut along the runner movement in the fixed mount, when the feed screw nut arrives stroke limit point, push the limit switch contact by switch press plate and make drive motors cut off the power supply, thereby reach the effect of stroke limit, but this structure stroke adjustment is difficulty comparatively, and positioning accuracy is lower.
The summary of the invention the purpose of this utility model provides the built-in door-rolling machine screw mandrel stopping means that a kind of stroke adjustment is convenient, positioning accuracy is high.
For achieving the above object, the built-in door-rolling machine screw mandrel of the utility model stopping means, form by fixed mount, travel switch, screw mandrel, feed screw nut, adjusting nut and hold-down screw, the two ends of screw mandrel are arranged in the fixed mount by axle sleeve, screw mandrel is provided with feed screw nut and adjusting nut, be provided with hold-down screw at the feed screw nut top, travel switch is installed in the chute both sides in the fixed mount, screw mandrel one end is connected with flexible axle one end, the flexible axle other end is connected with reducer, and screw mandrel one end outside fixed mount is provided with the flange that can be connected and fixed flexible axle end-fitting cover.
End axial centre position in that described screw mandrel is connected with flexible axle is processed with the sector that can cooperate with the flexible axle termination.
The tabular that sector on the end machining Cheng Nengyu screw mandrel that described flexible axle is connected with screw mandrel cooperates.
After adopting this structure, because screw mandrel one end is connected with flexible axle one end, the flexible axle other end is connected with reducer, therefore, fixed mount can be arranged on outside the door-rolling machine, regulates the requirement that the door-rolling machine stroke is convenient, positioning accuracy is high thereby reach.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Accompanying drawing is the main cross-sectional schematic of the built-in door-rolling machine screw mandrel of the utility model stopping means.
Among the figure: 1. flexible axle 2. flanges 3. fixed mounts 4. hold-down screws 5. screw mandrels 6. feed screw nuts 7. adjusting nuts 8. travel switches.
The built-in door-rolling machine screw mandrel of the utility model shown in specific embodiment accompanying drawing stopping means, by fixed mount 3, travel switch 8, screw mandrel 5, the feed screw nut 6, adjusting nut 7 and hold-down screw 4 are formed, the two ends of screw mandrel 5 are arranged in the fixed mount 3 by axle sleeve, screw mandrel 5 is provided with feed screw nut 6 and adjusting nut 7, be provided with hold-down screw 4 at feed screw nut 6 tops, travel switch 8 is installed in the chute both sides in the fixed mount 3, screw mandrel 5 one ends are connected with flexible axle 1 one ends, flexible axle 1 other end is connected with reducer, and screw mandrel 5 one ends outside fixed mount 3 are provided with the flange 2 that can be connected and fixed flexible axle 1 end-fitting cover; End axial centre position in that described screw mandrel 5 is connected with flexible axle 1 is processed with the sector that can cooperate with flexible axle 1 termination; The tabular that described flexible axle 1 and sector on the end machining Cheng Nengyu screw mandrel 5 that screw mandrel 5 is connected are cooperated.
