At present, the internal grinding machine is mainly used for grinding the surface of an inner hole formed by spreading cylindrical, conical or other plain lines and the end surface of the inner hole. When the stamping die is processed, the stamping die needs to be punched or grooved firstly, and then the inner grinder is used for grinding the formed holes or grooves, so that the surface of the stamping die is in a shape corresponding to a product, and the subsequent stamping die is convenient to stamp to form the product.

Related art for example, publication No. CN103962902A discloses an internal rounding machine, which comprises a machine body and a longitudinal workbench slidably connected with the machine body, wherein a transverse workbench is slidably connected above the longitudinal workbench, a transverse feeding mechanism is arranged on the transverse workbench, the transverse feeding mechanism is connected with a speed reducer, and the speed reducer is connected with a feeding control mechanism; the main scale of the grating scale is arranged on the transverse worktable along the feeding direction of the transverse worktable; the reading head of the grating ruler is arranged below the main ruler and is electrically connected with a digital display meter.

In the above-described related art, the inventors consider that: when processing stamping die, because stamping die general shape is the rectangle, adopt above-mentioned chuck to carry out the centre gripping and make stamping die comparatively difficult to make interior rounding machine to the suitability of work piece centre gripping relatively poor.

Disclosure of Invention

In order to improve the suitability of interior rounding machine to the work piece centre gripping, the purpose of this application is to provide an interior rounding machine.

The application provides an interior rounding machine adopts following technical scheme:

the utility model provides an internal rounding machine, includes the lathe bed, slide set up in slip subassembly on the lathe bed, set up in dull polish subassembly on the lathe bed, dull polish subassembly is located on the slip direction of subassembly that slides, be equipped with the chuck with the work piece centre gripping on the subassembly that slides, the cover has the fixed plate on the chuck, the fixed plate orientation one side of dull polish subassembly is equipped with fixed block and grip block, grip block and fixed block butt respectively in the roof and the diapire of work piece.

Through adopting above-mentioned technical scheme, when polishing the stamping die and add man-hour, place stamping die on the fixed block for stamping die's diapire butt in fixed block, roof butt in the grip block, then the drive subassembly that slides, drive chuck and fixed plate slide towards the dull polish subassembly. And after the grinding assembly extends into the hole of the stamping die, the sliding assembly drives the fixing plate to slide back and forth so that the grinding assembly polishes the stamping die. Consequently, through setting up the fixed plate, utilize grip block and fixed block to carry out the butt to stamping die's roof and diapire to on being fixed in the fixed plate with stamping die, make the fixed plate chuck get off the back and slide in the drive of the subassembly that slides, thereby be convenient for polish processing to stamping die.

Optionally, the sliding assembly comprises a sliding seat connected to the lathe bed in a sliding manner, a first driving part arranged on the lathe bed and used for driving the sliding seat to slide, and a second driving part arranged on the sliding seat and used for driving the chuck to rotate, and the chuck is rotatably arranged in the fixing plate.

By adopting the technical scheme, when the driving chuck rotates, the driving part II is started; when drive chuck and fixed plate make a round trip to slide, start driving piece one, drive the slide and slide towards the direction of keeping away from dull polish subassembly each other to realize stamping die and polish on dull polish subassembly, thereby be convenient for drive chuck and fixed plate together slide.

Optionally, the confession has been seted up in the fixed plate chuck pivoted mounting hole, chuck threaded connection in the mounting hole, the bottom sliding connection of fixed plate is on the slide, the one end fixedly connected with limiting plate of dull polish subassembly is kept away from to the mounting hole, the limiting plate is used for the restriction the fixed plate breaks away from the chuck towards after the dull polish subassembly slides.

By adopting the technical scheme, after the stamping die is placed between the clamping block and the fixing block, the first driving piece drives the chuck and the fixing plate to slide towards the grinding assembly; and after the stamping die is close to the sanding component, the driving part II drives the chuck to rotate, so that the fixed plate slides towards the sanding component under the rotation of the chuck, and the sanding component extends into the hole of the stamping die. When the limiting plate in the fixing plate abuts against the chuck, the fixing plate slides to the maximum position, the driving part II stops driving at the moment, and then the driving part I starts to drive the fixing plate and the stamping die to slide back and forth so as to polish the stamping die.
