Abstract
The invention relates to an improved center frame comprising a base, two lower supports, an upper support, fixation connecting blocks, threaded studs, supporting rollers, tightening nuts and tubes. The base is a rectangular steel plate as designed, two arc-shaped lower supports are fixed to the base in a welded manner, the upper support is connected to the top of the lower supports through fixing bolts, the fixation connecting blocks are fixedly connected to the tops of the arc-shaped lower supports in the welded manner, the fixation connecting block is fixedly arranged in the middle of the upper support in the welded manner, and the tubes are arranged in the fixation connecting blocks through the tightening nuts and are provided with the threaded studs inside in a threaded manner. The radius of the arc is large, shaft workpieces with large size can be machined, the vertical position of the supporting rollers can be adjusted by rotating the threaded studs, and the improved center frame is practical and convenient to disassemble.
Description
Technical field
The present invention relates to the centre frame for working shaft-like part, particularly relate to a kind of improvement rear center frame.
Background technology
The centre frame for working shaft-like part that lathe carries generally can only process the axial workpiece of maximum gauge 350mm, and some larger axial workpieces cannot be processed.
Traditional closed center rest have employed 3 point cantact, although grinding accuracy is high, the circularity of endoporus can be ensured when inner hole grinding, but three contact points all need to adjust position, centre of support after each replacing workpiece, consume long when changing workpiece, affect working (machining) efficiency, and during adjustment, stability is bad, affect machining accuracy, be unfavorable for producing processing work in enormous quantities.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of improvement rear center frame.
The present invention is achieved through the following technical solutions: a kind of improvement rear center frame, comprise base, support undercarriage, support added, be fixedly connected with block, threaded post, backing roll, clamp nut and sleeve pipe, described base is one piece of rectangular steel plates design, described base is welded and fixed the support undercarriage being provided with two arc-shapeds, support is connected with by set bolt added above described support undercarriage top, the support undercarriage top ends of described two arc-shapeds is all welded and fixed to be provided with and is fixedly connected with block, the added centre position of described support is also welded and fixed to be provided with and is fixedly connected with block, the described block inside that is fixedly connected with is provided with sleeve pipe by clamp nut, be spirally connected in described sleeve pipe and be provided with threaded post, described threaded post is rotationally connected and is provided with backing roll.
As preferably, described in be fixedly connected with block and be provided with three.
As preferably, described support is detachably added.
As preferably, described backing roll moves up and down by the rotation of threaded post.
Compared with prior art, the invention has the beneficial effects as follows: arc radius of the present invention is comparatively large, can process larger sized shaft-like workpiece, and threaded post can regulate the upper-lower position of backing roll by rotation, very practical, convenient disassembly; Not only ensure that grinding accuracy in addition, and convenient adjustment position, centre of support, improve operating efficiency, be applicable to producing processing work in enormous quantities.
