Abstract

The utility model discloses a short-stress-path rolling mill connecting shaft bracket. First pin shafts are connected with first connecting rods, second pin shafts are connected with the first connecting rods, second connecting rods are connected with the first connecting rods, third pin shafts are connected with the second connecting rods, upper sliders are located below the third pin shafts, bracket bodies are located on second lower sliders, connecting plates are connected with the first connecting rods, guide rods are connected with the connecting plates, the second lower sliders are located below the guide rods, backing plates are located above nuts, and the nuts are located above thin nuts. Couplings are supported by elasticity of springs, and the spring can absorb vibration and resist impact; compared with conventional pin shafts, the pin shafts have the advantages that diameter is increased, and shear resistance of the pin shafts is enhanced; therefore, the connecting shaft bracket is more smooth and reliable during operation, accident rate is reduced, and smooth production is guaranteed.

Description

A kind of short stress path rolling mill spindle bracket
Technical field
The utility model relates to spindle bracket field, specifically relates to a kind of short stress path rolling mill spindle bracket.
Background technology
Spindle bracket is positioned in the middle of short stress path rolling mill and milling train gear-box, be used for holding GSL concertina type drum-shaped tooth type shaft coupling, GSL concertina type drum-shaped tooth type shaft coupling two ends connect respectively short stress path rolling mill and milling train gear-box, but the mill speed of short stress path rolling mill is very fast, while especially arriving bar finish rolling end frame, mill speed is faster, in high-speed rolling process, GSL concertina type drum-shaped tooth type shaft coupling is accompanied by high-frequency vibration, this vibration is just directly conducted and has been given spindle bracket, on causing in bracket, the vibration of sliding block, to bearing pin, be threaded and cause high-frequency impact, cause bearing pin cross section to bear shearing force, bearing pin wearing and tearing, screw thread is rigidly connected loosening, thread damage, the equipment that affects is normally used, production is obstructed.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of short stress path rolling mill spindle bracket.
For realizing this technical purpose, scheme of the present utility model is: a kind of short stress path rolling mill spindle bracket, comprise the first bearing pin, first connecting rod, the second bearing pin, second connecting rod, the 3rd bearing pin, top shoe, back-up block, bracket, connecting plate, guide rod, the second sliding block, spring, backing plate, nut, thin nut, described the first bearing pin is connected with first connecting rod, described the second bearing pin is connected with first connecting rod, described second connecting rod is connected with first connecting rod, described the 3rd bearing pin is connected with second connecting rod, described top shoe is positioned at the 3rd bearing pin below, described bracket is positioned at the second sliding block, described connecting plate is connected with first connecting rod, described guide rod is connected with connecting plate, described the second sliding block is positioned at guide rod below, described backing plate is positioned at nut top, described nut is positioned at thin nut top.
As preferably, described second connecting rod is connected by the first bearing pin with first connecting rod.
As preferably, described guide rod is connected by bearing pin with connecting plate.
As preferably, described guide rod is connected by connecting plate with first connecting rod.
As preferably, below described guide rod, be inserted in spring.
The utility model is broken the traditional concept of spindle bracket in the past, with the elastic force of spring, hold shaft coupling, spring can absorb vibration, shock-resistant, and compare bearing pin in the past, its diameter all increases, the anti-shear performance of bearing pin also strengthens, can be more steadily reliable when therefore spindle bracket is worked, reduce accident rate, ensure to produce and carry out smoothly.
Accompanying drawing explanation
Fig. 1 is the spindle carrier structure schematic diagram of prior art;
Fig. 2 is structural representation of the present utility model;
In figure: the first bearing pin 1, first connecting rod 2, the second bearing pin 3, second connecting rod 4, the 3rd bearing pin 5, top shoe 6, left screw rod 7, stop nut 8, Double-ended nut 9, right screw rod 10, the first sliding block 11, back-up block 12, bracket 13, connecting plate 14, guide rod 15, the second sliding block 16, spring 17, backing plate 18, nut 19, thin nut 20.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 2, a kind of short stress path rolling mill spindle bracket of the utility model embodiment, comprise the first bearing pin 1, first connecting rod 2, the second bearing pin 3, second connecting rod 4, the 3rd bearing pin 5, top shoe 6, bracket 13, connecting plate 14, guide rod 15, the second sliding block 16, spring 17, backing plate 18, nut 19, thin nut 20, described the first bearing pin 1 is connected with first connecting rod 2, described the second bearing pin 3 is connected with first connecting rod 2, described second connecting rod 4 is connected with first connecting rod 2, described the 3rd bearing pin 5 is connected with second connecting rod 4, described top shoe 6 is positioned at the 3rd bearing pin 5 belows, described bracket 13 is positioned at the second sliding block 16, described connecting plate 14 is connected with first connecting rod 2, described guide rod 15 is connected with connecting plate 14, described the second sliding block 16 is positioned at guide rod 15 belows, described backing plate 18 is positioned at nut 19 tops, described nut 19 is positioned at thin nut 20 tops.
As preferably, described second connecting rod 4 is connected by the first bearing pin 1 with first connecting rod 2.
As preferably, described guide rod 15 is connected by bearing pin with connecting plate 14.
As preferably, described guide rod 15 is connected by connecting plate 14 with first connecting rod 2.
As preferably, spring 17 is inserted in described guide rod 15 belows.
Operation principle of the present utility model: break the traditional concept of spindle bracket in the past, with the elastic force of spring, hold shaft coupling, it can cushion the vibratory impulse that GSL concertina type drum-shaped tooth type shaft coupling imposes on top shoe 6 and the second sliding block 16, and compare bearing pin in the past, its diameter all increases, the circular section of bearing pin is long-pending also all to increase, and bearing pin can bear larger shear stress, so can be more steadily reliably during the work of spindle bracket.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
