Description
Technical field
The utility model relates to a kind of devices of engineering machinery, more particularly, to the embedded railway frog of railway communication line road
The angle rotary workbench of processing manufacturing industry.
Background technique
Current processing method is that the railway frog for having as many as eight sections of angles is placed on planer-type milling machine work top, every by break
Section difference centering, is processed again after being compressed with pressing plate, and two operators need to carry out phase according to the number of segment of single railway frog angle
The disassembly, correction, clamping for answering number, complete the Milling Process of embedded railway frog.
Embedded railway frog is ZGMn13 high manganese steel material, has high rigidity, high abrasion characteristic, and length is long, appearance curved surface
Complexity must use molding cutter milling when processing, and maximum depth of cut, in 7mm, maximum cutting width is in 53mm, cutting
Vibration is big.Rigidity and electric parameter for general NC lathe can not meet cutting and require, and the equipment for being able to satisfy requirement is thrown
Money is big, causes to perplex to enterprise.
Taking the method for manually adjusting at present, the time is long, effect to completing the correction of every embedded railway frog, fill, tear open often
Rate is low；Relative correction trueness error is big；Labor intensity of workers is big；Output is at high cost.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of by railway frog through primary correction clamping, by manual
Automatically controlled button is operated to realize the angle rotary of workbench, step-cut milling is carried out to the railway frog of multistage angle, to complete entirely
Process.
The utility model aim is to avoid by manually repeatedly being filled, being torn open, correction situation and a kind of servo electricity provided
Machine retarder ball-screw-transmission disc spring locks angle rotary table product.
Technical solution adopted by the utility model to solve the above technical problems is as follows: being provided with zero on corner angle rectangular table face
Part installation ladder-type trough, bottom surface are supported by three pieces of base planes, and plane studs with one section of wear-resisting steel plate on the pedestal at both ends, improves and slides
The wearability at dynamic position, workbench bottom centre position are pivot axis center, configure a cylindrical roller thrust bearing and two
The center of deep groove ball bearing locating shaft.Rotary encoder apparatus is installed, for the angle of revolution of feedback operation platform in axis hole.Work
Platform bottom is distributed three groups of concentric arcs ladder-type troughs on the basis of center, in length direction, in three pieces of base intracavities and workbench bottom
Symmetrical totally ten disc spring locking cylinders on the corresponding circumference of three groups of portion ladder-type trough, the pull rod of disc spring locking cylinder is in disc spring elasticity
Deformation is lower to be bonded locking workbench with the interior step of ladder-type trough, and when weakening and resist strong cutting or the impact endurance test shock of generation is to biography
The influence of moving part precision and service life.The hydraulic interface parallel connection of ten disc spring locking cylinders accesses pipeline oil inlet, works as workbench
When needing rotational angle, starts hydraulic power unit to provide pressure oil and give cylinder inner piston, when pressure overcomes disc spring coupling mechanism force,
It relieves to table latch, on the contrary locking workbench.It is appropriate apart from the centre of gyration between two pieces of pedestals below workbench
Radial location is equipped with servo motor retarder ball-screw-transmission case, is driven by servo motor retarder, passed by two groups of teeth wheel
Ball-screw rotation is passed, the feed screw nut seat equipped with bearing guide chute block is moved back and forth along lead screw axis, below workbench
Sliding axle with bearing drives sliding axle along guide chute direction and lead screw axis in guide chute when nut seat moves
Make the movement of arc track, realizes the revolution of workbench.
The utility model has the beneficial effects that need to only manipulate required angle of revolution after the completion of workpiece is through primary correction clamping
Carry out being machined to complete paragraph by paragraph, without it is multiple tear open, school, dress, significantly shorten stand-by time, alleviate labor intensity,
To workpiece accuracy, raising production efficiency, reduction production cost is guaranteed, increasing economic efficiency has apparent good effect.
