Abstract
The utility model relates to the field of machinery, particularly to a faceplate supporting device for a floor-type lathe. The faceplate supporting device comprises a base, a supporting shaft and a bracket, wherein the bracket is hinged to the base through the bracket; a supporting platform is arranged on the bracket; a group of symmetrically arranged riding wheel mechanisms is arranged on the supporting platform; the space between the two riding wheel mechanisms is adjustable; two adjusting and limiting devices are arranged on the supporting platform, and respectively support the separated directions of the two riding wheel mechanisms. According to the arrangement, when a workpiece is clamped, the force carrying direction can be found movably, and the condition that the two riding wheels are in contact simultaneously is ensured, so that the stability of processing is ensured, and the processing precision is ensured.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of for face lathe floral disc bracing or strutting arrangement.
Background technology
In the turning processing to huge revolving workpiece for barrel outer surface and section, at present, in process due to the excessive machining accuracy that affects of cylinder part weight, specifically because rotating cylinder workpiece weight is excessive, make the main shaft of thimble one end be subject to excessive power vertically downward to cause micro-flexural deformation, thereby the position that causes main shaft and floral disc because of stressed downward displacement occurs, when main shaft is rotary, can forms circle and beat, thereby affect machining accuracy.
Utility model content
The utility model object is to provide a kind of face lathe floral disc bracing or strutting arrangement, thereby object is to solve, weight because of rotating cylinder is excessive causes that main shaft occurs bending and deformation and affect the problem of machining accuracy.
The utility model comprises base, back shaft, bracket, described bracket is hinged on described base by back shaft, at described bracket, be provided with a support platform, one group of wheel holding mechanism being arranged symmetrically with is set in described support platform, spacing between described two wheel holding mechanisms is adjustable, two regulation limiting devices are set in described support platform, and described regulation limiting device is supported on respectively described two directions that wheel holding mechanism separates.
The utility model is supported under workpiece while using, when workpiece preponderance, delivery mechanism gives floral disc radial support power, can prevent that like this main shaft from occuring bending and deformation, thereby improved machining accuracy, in production, can coordinate workpiece according to the distance between two wheel holding mechanisms of size adjustment of processing work; Have between bracket and base again and form hinge by back shaft, this set is when card engaging workpiece, and can walk about to look for is subject to force direction, guarantees that two support rollers contact simultaneously, has guaranteed like this stability of processing, has guaranteed machining accuracy.
Wheel holding mechanism described in the utility model comprises support roller, roller frame, supporting-roller shaft, self-aligning roller bearing, described support roller is fixed in supporting-roller shaft by self-aligning roller bearing, described supporting-roller shaft is supported in described roller frame, and described roller frame is fixed in described support platform by bolt, nut; In described support platform, T-slot is set, slideable being arranged in described T-shaped groove of spiral shell head of described bolt; This set can be so that wheel holding mechanism slides in support platform, and the distance of adjusting between two wheel holding mechanisms adapts to different workpieces, has guaranteed precision, the stability of processing.
Regulation limiting device described in the utility model comprises adjusting jackscrew and is fixed on the back-up block in described support platform, the screwed hole of one level is set on described back-up block, described adjusting jackscrew is threaded in the screwed hole of described back-up block, and described adjusting jackscrew contacts with the roller frame of described wheel holding mechanism; By regulating jackscrew, the spacing between wheel holding mechanism is adjusted, by the position that regulates jackscrew to control supporting roller base, can guarantee that the surface of support roller and floral disc fully contacts, and the position that can finely tune floral disc and the main shaft constant precision and stability of controlling main shaft in the vertical direction.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the sectional drawing of Fig. 1.
