Description
Technical field
The utility model relates to rolling mill screwdown device, is a kind of screw thread pair running-in machine specifically.
Background technology
Housing screw is the important component part of rolling mill screwdown device.Along with metallurgy industry technical development, the steel rolling equipment that roll-force is large, stroke is long, linear velocity is fast more and more for the production of, machining accuracy, the screw thread pair contact precision etc. of depressing screw thread have been proposed to very high requirement.
Press down screw-pairs is mainly made up of housing screw and screw box.As shown in Figure 1, in the course of the work, housing screw by the spline on it by the positive and negative rotation of driven by motor, and by being axially fixed in the screw box in frame, force the upper and lower motion of housing screw, realize roll chock and roll moves up and down, reach the object of adjusting roll relative position.
Housing screw is steel alloy, and screw box is copper alloy.In work, on screw thread, working face bears roll and passes to the equilibrant force of press down screw-pairs.In the time that amount of rolling changes, press down screw-pairs need to carry engagement under load condition, if contact rate does not reach designing requirement, the contact stress of screw thread pair working surface will sharply increase, and cause that working surface sharply weares and teares, grinds wound, even causes part to be scrapped.So surface quality, the contact rate of screw thread pair etc. of design to press down screw-pairs all proposed high requirement.
In actual processing, the defect that the geometry of the form of thread and thread surface quality exist some to affect contact rate unavoidably, improve the contact rate of screw thread pair working face, just requires press down screw-pairs to carry out facing-up, makes it reach technical requirement.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and a kind of screw thread pair running-in machine is provided, and the real use state of this unit simulation press down screw-pairs is realized the facing-up of screw thread pair.
Realizing the technical solution of the utility model is: a kind of screw thread pair running-in machine, is characterized in that: comprise operating platform, screw box, pull out seat, housing screw, spline housing, workbench and guide rail; Described screw box is fixedly installed on operating platform; The described seat that pulls out is fixedly mounted on the workbench with guide rail, and this pulls out a top and is fixedly connected with spline housing; Described housing screw splined shaft portion is placed in and pulls out in seat through spline housing, and the threaded portion of described housing screw, through operating platform, engages composition screw thread pair with screw box.
Described screw box is installed in the nut seat on operating platform, on it, uses and fixes with the pressing plate of connecting bolt.
Described workbench has gear ring around, this gear ring and the gear engagement that is connected motor, thus obtain rotational power.
Described operating platform is by seat supports, and this bearing is cast on concrete pedestal, can better bear the weight of package unit.
Described seat, housing screw, spline housing, workbench and the guide rail of pulling out is all placed in the cement pit under operating platform, handled easily.
" facing-up " is paired part instrument and a kind of processing method of grinding object each other, and screw thread pair running-in machine is the running-in machine of housing screw and screw box.
The beneficial effects of the utility model are:
1, whole device imitates press down screw-pairs actual working state, and facing-up is effective, precision is high;
2, apparatus structure is simple, easy for installation, easy to implement.
3, can select the vertical car of discarded C512-1A to do power, transmission system and the workbench of facing-up, be all on-the-spot twice laid.

Detailed description of the invention
As shown in Figures 2 to 4: a kind of screw thread pair running-in machine, comprises operating platform 4, screw box 2, pulls out seat 7, housing screw 1, spline housing 6, workbench 8 and guide rail 9; Described screw box 2 is installed in the nut seat 3 on operating platform 4, fixing with the pressing plate 15 with connecting bolt 14 on it.Described pulling out on seat 7 workbench 8 that are fixedly mounted on guide rail 9, this pulls out seat 7 tops and is fixedly connected with spline housing 6; Described housing screw 1 splined shaft portion is placed in and pulls out in seat 7 through spline housing 6, and the threaded portion of described housing screw 1, through operating platform 4, engages composition screw thread pair with screw box 2.Described workbench 8 has gear ring 12 around, and this gear ring 12 engages with the gear 11 that is connected motor 10, thereby obtains rotational power.Described operating platform 4 is supported by bearing 5, and this bearing 5 is cast on concrete pedestal 13, can better bear the weight of package unit.Described seat 7, housing screw 1, spline housing 6, workbench 8 and the guide rail 9 of pulling out is all placed in the cement pit under operating platform 4, handled easily.
Power, transmission system and the workbench 8 of selecting the vertical car of discarded C512-1A to do facing-up are on-the-spot twice laids.The structure that is spline according to housing screw 1 one end, design spline housing 6 connects the vertical lathe workbench of rotation and housing screw 1, drives housing screw 1 to rotate; The groove that on recycling screw box 2, width is 200, design nut seat 3, with pressing plate 15, screw box 2 is fixing with nut seat 3, and nut seat 3 is fixed on the fixing operation platform 4 of building on top.
Process of lapping of the present utility model: first housing screw 1 is hung in to pulling out in seat 7 of screw thread pair running-in machine, and work good with spline housing 6, at this moment the weight of housing screw 1 is born by pulling out seat 7.In the time of workbench 8 forward, drive housing screw 1 forward by group seat 7 and the spline housing 6 that are fixed on workbench 8, housing screw 1 forces housing screw 1 to move from bottom to top by the screw box 2 and the nut seat 3 that are fixed on operating platform 4, at this moment its weight is born by screw box 2 and nut seat 3, the real use state (just opposite direction) of simulation press down screw-pairs, completes housing screw 1 and screw box 2 milling tool and the process of lapping that grinds object each other; In the time that workbench 8 reverses, housing screw 1 exits from top to bottom, once simulates process of lapping and finishes, and the stroke of housing screw 1 is determined jointly by the reach of spline length and screw box 2.As required, can one or many simulate and grind to reach Cui effect.
