Abstract
Framing shaping machine expanding roller seat nut connecting structure, comprise guide rail and roller seat, roller seat is fixed with Stretching rollers, roller seat bottom is provided with walking roller, walking roll-in is on guide rail, nut and screw mandrel are spirally connected and are fixed together, and square tube is fixed with locating piece by screw, in the top sleeve of the locating piece circular recess on roller seat; Nut is fixed together by screw and square tube, square tube forms strip hole, positioning screw to be screwed onto on roller seat and sleeve in strip hole.Its nut and screw mandrel still can work on after there is little distortion use, extend the service life, particularly nut of framing shaping machine and the service life of screw mandrel.
Description
Technical field:
The utility model relates to framing shaping machine technical field, more specifically to a kind of expanding roller seat nut connecting structure of framing shaping machine.
Background technology:
See shown in Fig. 1, Fig. 2, existing framing shaping machine comprises casing A1, Stretching rollers A2, and screw mandrel A3 and nut A4, screw mandrel A3 and nut A4 coordinate and drive Stretching rollers A2 to move linearly along screw mandrel A3, by cloth around on Stretching rollers A2, realize the stretching of cloth by the change of the spacing of two Stretching rollers A2.Its weak point is: 1, nut A4 is fixed on tentering roller seat A6 by two screw rod A5, nut A4 is dead, because casing A1 works high temperature more than 200 DEG C, so nut A4 is yielding, nut distortion is rear and screw mandrel is stuck, so just cannot use, simultaneously, nut often needs to oil, and safeguards and also extremely bothers.2, because screw mandrel and nut at high temperature work for a long time, so screw mandrel also can be sent out an a little little distortion, after screw mandrel distortion, nut is also easily stuck, causes and cannot use.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of framing shaping machine expanding roller seat nut connecting structure, and its nut and screw mandrel still can work on after there is little distortion use, extends the service life of framing shaping machine.
Technology solution of the present utility model is as follows:
Framing shaping machine expanding roller seat nut connecting structure, comprise guide rail and roller seat, roller seat is fixed with Stretching rollers, roller seat bottom is provided with walking roller, walking roll-in is on guide rail, nut and screw mandrel are spirally connected and are fixed together, and square tube is fixed with locating piece by screw, in the top sleeve of the locating piece circular recess on roller seat;
Nut is fixed together by screw and square tube, square tube forms strip hole, positioning screw to be screwed onto on roller seat and sleeve in strip hole.
Described square tube forms two strip holes, two strip holes symmetrically shape are distributed on two side plates of square tube, two positioning screws respectively sleeves in strip hole.
The beneficial effects of the utility model are:
Its nut and screw mandrel still can work on after there is little distortion use, extend the service life of framing shaping machine.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of prior art;
Fig. 2 is the annexation schematic diagram of nut and roller seat in prior art;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the schematic perspective view of the utility model square tube part.
In Fig. 3,4: 1, guide rail; 2, roller seat; 21,3, Stretching rollers; 4, walking roller; 5, nut; 6, screw mandrel; 7, square tube; 71, strip hole; 8, locating piece; 9, positioning screw.
Detailed description of the invention:
Embodiment: see shown in Fig. 3,4, framing shaping machine expanding roller seat nut connecting structure, comprise guide rail 1 and roller seat 2, roller seat 2 is fixed with Stretching rollers 3, roller seat 2 bottom is provided with walking roller 4, and walking roller 4 is pressed on guide rail 1, and nut 5 and screw mandrel 6 are spirally connected and are fixed together, square tube 7 is fixed with locating piece 8 by screw, in the top sleeve of the locating piece 8 circular recess 21 on roller seat 2;
Nut 5 is fixed together by screw and square tube 7, square tube 7 forms strip hole 71, positioning screw 9 to be screwed onto on roller seat 2 and sleeve in strip hole 71.
Described square tube 7 forms strip hole 71,71, two, two strip holes symmetrically shape be distributed on two side plates of square tube 7, two positioning screws 9 respectively sleeves in strip hole 71.
Operation principle: square tube 7 has certain free degree space on roller seat 2, nut is made also to be provided with certain free degree space relative to screw mandrel, this free degree space is when there are some little distortion in nut 5 and screw mandrel 6, nut 5 still can move along screw mandrel 6, so just extend the service life of the service life of framing shaping machine, particularly nut and screw mandrel.
