The integral center plate swing bolster fulcrum seat milling positioning clamping device has the advantages that the device has high positioning precision and can automatically complete the positioning of the middle part through the positioning block with both sides provided with circular arc surfaces under the action of the gravity of a workpiece during workpiece lifting; moreover, a lower positioning mechanism automatically completes centering positioning during clamping; in addition, in order to ensure the safe machining for the workpiece, fabrication holes of an upper part and a lower part of the workpiece are used as clamping points, and the tensioning mechanisms press the workpiece in a mode of spiral tension and compression; meanwhile, the device has simple, convenient, quick and reliable operation, and the two heel blocks can ensure the perpendicularity of the workpiece.
Description
Technical field
The utility model relates to one cartridge bolster fulcrum block milling positioning clamping device.
Background technology
Bolster is a part of railway freight car bogie, and bolster of the present utility model is a kind of one cartridge bolster, sees Fig. 4, and this bolster 8 has center bearing upright rib 8-1, fabrication hole 8-2, and center bearing plane and upright rib inner face 8-3 are polished surfaces.The two sides of this bolster respectively are provided with fulcrum block, by technological requirement, need carry out plane processing to the surface of fulcrum block.Because the structure of bolster is special, its working position size is less, and the two ends size is bigger, can not horizontal positioned process, so take to press line processing by manually marking the machined surface processing line with the single armed milling machine.Because bolster of processing must carry out twice location, clamping, so machining accuracy is poor, the mass property fluctuation is big, labour intensity is big, processing non-cutting time, long, production efficiency was carried not high.
The utility model content
The purpose of this utility model is to propose a kind of one cartridge bolster fulcrum block milling positioning clamping device, process that a bolster utilizes this positioning clamping device need only carry out one-time positioning, clamping gets final product.
For achieving the above object, general plotting of the present utility model is: because the processing of bolster fulcrum block is carried out after bolster cartridge and upright rib fine finishining thereof, by mach general positioning principle, should be the location benchmark with the polished surface, consider that simultaneously fulcrum block is positioned at the middle part left and right sides of bolster cartridge and end bolster retaining, and longitudinal centre line symmetry with respect to bolster, therefore, the locating surface that this device is the middle part with the bolster cartridge face that processed and upright rib circumference thereof, keeping off the width center with the bolster that is positioned at fulcrum block one end is the located lateral benchmark, consider that simultaneously the upright rib of cartridge inevitably exists mismachining tolerance and bolster retaining to have the casting error, therefore this positioning clamping device is taked the centering detent mechanism, can not be subjected to the error effect of workpiece locating surface.
The concrete scheme of the utility model is as follows:
The utlity model has pedestal, the upper and lower of pedestal vertical wall lateral surface respectively is fixed with by piece, the middle part is fixed with locating piece, whenever be provided with the tensioning mechanism that is connected on the pedestal vertical wall by between piece and the locating piece, be provided with the detent mechanism that is connected on the pedestal vertical wall by below the piece in the bottom.
Described tensioning mechanism has screw rod that is connected with pedestal vertical wall upper screwed hole and the nut that cooperates and be in pedestal vertical wall inboard with screw rod, and the front end of screw rod is fixed with the baffle plate that is used for workpiece pressing.
Described locating piece dual-side has the radian that coincide with the upright rib inner peripheral surface of one cartridge.
Two orientation direction posts about described detent mechanism has, about the top of two orientation direction posts to be provided with two thread rotary orientation opposite screw mandrel, the middle part of screw mandrel is by the limit base location that is fixed on the pedestal, and two of screw mandrel respectively is threaded and is used for limited block to left and right sides clamping work pieces.
The limited block sliding area of corresponding detent mechanism is provided with slide on the pedestal, and limited block and slide are slidingly matched.
The utility model is simple in structure, positioning accuracy is high, under the effect of workpiece gravity, is location that the locating piece of arc surface is finished the middle part automatically by both sides in the work piece hoisting process, and following detent mechanism is finished the centering location automatically in the process that clamps; For guaranteeing the process safety of workpiece, utilize its technology hole wall as clamping point at upper and lower two positions of workpiece in addition, tensioning mechanism adopts the mode workpiece pressing of spiral tension and compression, and is easy and simple to handle, rapid, reliable, and two lean on piece can guarantee the vertical of workpiece.After adopting this device, need not to draw processing line again, but one-time positioning, clamp the processing can finish left and right sides two fulcrum blocks on the single armed milling machine, guarantee machining accuracy, process time is short, has significantly reduced non-cutting time, and production efficiency significantly promotes.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a configuration diagram of the present utility model;
Fig. 2 is the side view of Fig. 1;
