Abstract
The utility model discloses a center frame of a screw rolling machine. The center frame is characterized by comprising a bottom plate, a slide rail, a center bracket and a slide block, wherein the slide rail is arranged on the bottom plate; an installing hole for installing a workpiece is formed in the upper end of the center bracket; and the slide block is arranged at the bottom end of the center bracket, and is provided with a sliding chute matched with the slide rail. Compared with the prior art, the center frame has the advantages that the slide rail is in guiding fit with the slide block, and the entire center bracket moves forwards and backwards horizontally, so that the center position of the workpiece is more stable during processing, the processing precision and accuracy are increased greatly, and the defective rate is lowered.
Description
Technical field
The utility model relates to a kind of parts of screw-rolling machine.Relate in particular to a kind of screw-rolling machine centre frame.
Background technology
The centre frame of screw-rolling machine is used for clamping workpiece, the important composition parts of screw-rolling machine, in existing screw-rolling machine, utilize centre frame to deflect to adjust the location of workpiece, the left and right is in the center like this, but minor variations has occured in upper-lower position, and the workpiece after processing is beated because of centre frame and produced bad phenomenon greatly, needs to improve for this reason.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of screw-rolling machine centre frame that adds workpiece centre position stability in man-hour for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of screw-rolling machine centre frame is characterized in that comprising
Base plate;
Slide rail is located on aforesaid base plate;
Center bearing bracket, upper end have the installing hole for workpiece setting; And
Slide block is located at the bottom of aforementioned center bearing bracket and is had the chute adaptive with aforementioned slide rail.
Further, described slide rail two ends are provided with pressing plate, and described slide block is between aforesaid pressing plate.For realizing that slide block moves back and forth automatically, the inwall of described pressing plate is provided with a back-moving spring from all forming storage tank outside to inside in this storage tank, and the outer end of this back-moving spring is stretched out storage tank and can be contacted with the outer wall of center bearing bracket.
Form a bar-shaped trough on described base plate, and described slide rail is arranged in this bar-shaped trough by abaculus.Abaculus can utilize self big or small setting angle of adjusting slide rail, thereby satisfies the depth of parallelism of slide rail and screw-rolling machine mould, is beneficial to the accuracy that improves processing work.
Compared with prior art, the utility model has the advantage of: coordinate with the guiding of slide block by slide rail, the center bearing bracket integral level is moved around, the center that adds like this workpiece in man-hour is more stable, and machining accuracy and accuracy greatly improve, and defect rate reduces.
