In prior art, the general grinding machine that adopts is repaired steel rod, because steel rod weight is large and usually adopt the mounting means of back dead centre, can damage the top of grinding machine in repair process; In addition, steel rider grinding machine can affect the precision of grinding because of external vibration in grinding process, therefore, when steel rider grinding, needs to eliminate external vibration, thus improves grinding accuracy, and then the quality of raising product; In addition, grinding machine is on steel rider during machine, and often occur that steel rider swings and steel rider falls too fast situation, because steel rider roll shape is more, weight large, the impulsive force reinforcement that steel rider is produced grinding machine, directly affects the machining accuracy of steel rider.The weak point that Here it is existing for prior art.
Summary of the invention
Technical problem to be solved in the utility model is exactly for the deficiency existing for prior art, and provides a kind of steel rider to repair the technical scheme of special purpose grinder.
This programme is achieved by the following technical measures: a kind of steel rider repairs special purpose grinder, include lathe bed, tailstock, grinding carriage, the headstock, described grinding carriage is provided with grinding wheel drive mitor, the described headstock is provided with headstock motor, the bottom of described lathe bed is provided with grinder foundation, the upper surface of this grinder foundation is provided with the closed damping trough of at least one circle, and the width of described damping trough is more than or equal to 300mm; The side of described tailstock is provided with the first live centre, and side relative with described tailstock on the headstock is provided with the second live centre; Guide rail on front side of described lathe bed is provided with two slides matched with guide rail, each slide is provided with hydraulic cylinder, the top of this hydraulic cylinder is provided with the roll neck support member matched with steel rider.
Further improvement of the utility model also has, and described first live centre is connected with tailstock by bearing, and described second live centre is connected with the headstock by bearing.
Further improvement of the utility model also has, and the axis of described first live centre and the second live centre is on same straight line.
Further improvement of the utility model also has, and what described bearing adopted is Biserial cylindrical roller bearing.
Further improvement of the utility model also has, and the inner surface of described roll neck support member is provided with wearing layer.
Further improvement of the utility model also has, and the top of described roll neck support member has the dovetail groove that width of rebate is greater than slot bottom width.
Technical characterstic of the present utility model and good effect are:
(1) bottom of described lathe bed is provided with grinder foundation, and this grinder foundation upper surface is provided with the damping trough that at least one circle is closed, and the width of described damping trough is more than or equal to 300mm; When roll dressing, this grinder foundation can eliminate outside vibration, thus improves grinding accuracy, and then improves the quality of rolled products;
(2) side of described tailstock is provided with the first live centre, and side relative with described tailstock on the headstock is provided with the second live centre; After the two ends of large-scale steel rider are arranged on live centre respectively, steel rider and top dieback can be avoided the top damage caused, thus extend top service life;
(3) guide rail on front side of described lathe bed is provided with two slides matched with guide rail, each slide is provided with hydraulic cylinder, the top of this hydraulic cylinder is provided with the roll neck support member matched with steel rider, before steel rider is placed on grinding machine, first steel rider is placed on roll neck bracing frame, thus the impact alleviated lathe bed, and then improve the grinding accuracy of roll.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model detailed description of the invention.
In figure, 1 is headstock motor, and 2 is the headstock, and 3 is the second live centre, and 4 is grinding wheel drive mitor, and 5 is grinding carriage, and 6 is tailstock, and 7 is roll neck support member, and 8 is hydraulic cylinder, and 9 is slide, and 10 is lathe bed, and 11 is grinder foundation, and 12 is the first live centre, and 13 is damping trough.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, a kind of steel rider repairs special purpose grinder, include lathe bed 10, tailstock 6, grinding carriage 5, the headstock 2, described grinding carriage 5 is provided with grinding wheel drive mitor 4, the described headstock 2 is provided with headstock motor 1, the bottom of described lathe bed 10 is provided with grinder foundation 11, the upper surface of this grinder foundation 11 is provided with the closed damping trough 13 of at least one circle, the width of described damping trough 13 is more than or equal to 300mm, grinder foundation 11 can adopt cast mineral manufacture, there is very high damping property, while itself intensity of guarantee, improve the machining accuracy of lathe.
