Description
Technical field
The utility model relates to metallurgy, machinery manufacturing industry, particularly a kind of bearing pin flat surface grinding anchor clamps of slab caster chain type dummy bar.
Background technology
A kind of chain type dummy bar of slab caster is to be formed by connecting by a plurality of chain links and bearing pin, for the dummy bar that assembles only with to a direction bending, oppositely then can not be crooked.Because the downwarp amount to the whole back-flexing of dummy bar has certain requirement, therefore, the relative dimensions of each chain link and bearing pin all has higher requirement.Every dummy bar has the dozens of bearing pin usually, in order to prevent error accumulation, guarantees the whole assembly quality of whole dummy bar, must strict size and the form and position tolerance of controlling in the actual process of each bearing pin.
The processing technology traditional to bearing pin is: the bearing pin cylindrical is machined by lathe and grinding machine, and the bearing pin plane mills out on milling machine.In reality processing, the tolerance distribution is bigger during milling bearing pin plane, and size and form and position tolerance be cannot say for sure to demonstrate,prove, and the Biao Mian Cu Unfeigned degree on bearing pin plane also is difficult for reaching requirement.Therefore, the crudy that adopts method for grinding to obtain.Usually, the workbench of surface grinding machine adopts electromagnetic worktable, and flat surface grinding adds man-hour, and the general direct suction of workpiece is on electromagnetic worktable, and grinding will be realized in the dummy bar bearing pin location that can't directly be installed, and must adopt the frock solution orientation problem that is installed.
The utility model content
Task of the present utility model provides a kind of chain type dummy bar bearing pin flat surface grinding anchor clamps, the problem that bearing pin can't directly be installed and locate when it had solved the grinding of dummy bar bearing pin processing technology midplane.
The technical solution of the utility model is as follows:
A kind of chain type dummy bar bearing pin flat surface grinding anchor clamps, it is made up of clamp body, set bolt, cambered surface pressing plate, spheric washer and hold-down nut, described clamp body is equipped with anchor clamps and base plate, be provided with the anchor clamps of relative installing at the base plate dual side-edge, set bolt is housed on base plate, cambered surface pressing plate, spheric washer and the hold-down nut that is pressed on the workpiece is being installed on the set bolt.
The utility model uses a kind of bearing pin flat surface grinding anchor clamps, has improved dummy bar bearing pin processing technology, former cause milling machine is directly finished plane processing change into, carries out plane roughing by milling machine earlier, finishes fine finishining by surface grinding machine then.Given full play to the high and high advantage of surface grinding machine machining accuracy of milling machine working (machining) efficiency, working (machining) efficiency and crudy all are improved.
Bearing pin flat surface grinding anchor clamps of the present utility model can directly be inhaled on electromagnetic worktable, use semicircle pressing plate and spheric washer, and the location datum level can be proofreaied and correct at any time, and two above workpiece simultaneously can be installed.
This bearing pin flat surface grinding clamp structure is simple, and the error that is installed is little, and the location that is installed is reliable, easy to use, has improved working (machining) efficiency and crudy widely, can be widely used in the occasion on machining high-precision plane on cylindric workpiece.
Description of drawings
Fig. 1 is the structural representation of a kind of chain type dummy bar bearing pin flat surface grinding anchor clamps of the present utility model.
Fig. 2 is by left TV structure schematic diagram shown in Figure 1.
Fig. 3 is the schematic perspective view of Fig. 1 bearing pin flat surface grinding anchor clamps.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the utility model is a kind of chain type dummy bar bearing pin flat surface grinding anchor clamps, and it is made up of clamp body 1, set bolt 5, cambered surface pressing plate 4, spheric washer 3 and hold-down nut 2.Clamp body 1 is equipped with anchor clamps 11 and base plate 12, and the base plate height carries out the required surplus of autogenous grinding in the time of need considering to use the space of gage measuring needs and calibrate the location benchmark.
Be provided with the anchor clamps 11 of relative installing at base plate 12 dual side-edges, the anchor clamps 11 among Fig. 3 are provided with two pairs, and every pair of anchor clamps 11 are installed relatively.Install and fix bolt 5 on base plate 12, the set bolt 5 among Fig. 3 is arranged on the centre of every pair of anchor clamps 11.What show in the diagram of present embodiment is the structure that once can fix two workpiece.Just as shown in fig. 1, two workpiece 7 are inserted and put between the anchor clamps 11 that are fixed on paired arrangement, and set bolt 5 has been installed between two workpiece 7.Certainly, according to bearing pin size, manufacturing batch and plane Grinder bench specification, the structure that can be designed to fix simultaneously a plurality of workpiece, for example once fix three workpiece, or four workpiece, or multiplex's part more, between per two workpiece, should install and fix bolt, be convenient to insert and put.
Cambered surface pressing plate 4, spheric washer 3 and the hold-down nut 2 that is pressed on the workpiece 7 is being installed on the set bolt 5.Cambered surface pressing plate 4 outer surfaces are through grinding.Use spheric washer 3, it is inhomogeneous to eliminate the thrust that causes because of set bolt 5 position deviations, prevents the damage of workpiece 7 outer surfaces.
Clamp body 1 of the present utility model is to be made by ferrimagnet, can utilize electromagnetic worktable.Used ferrimagnet must have the advantage that distortion is little, dimensional stability is good.This clamp body 1 preferably adopts casting pig through annealing in process, for the purpose of economical, quick, also can adopt Welding Structure and through stress relief annealing.
When using the utility model, clamp body is placed on positions the bottom surface autogenous grinding on the surface grinding machine workbench earlier; Be placed on workpiece on the clamp body and adjust the position, with set bolt and spheric washer by the cambered surface pressing plate with Work-sheet pressing on clamp body.The dummy bar bearing pin just can carry out grinding at surface grinding machine like this.The dummy bar bearing pin after grinding, its dimensional tolerance can be controlled at ± 5 μ m in, form and position tolerance and Biao Mian Cu Unfeigned degree can both reach requirement, result of use is fine.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention conversion, the modification of the foregoing description.
