Abstract
The utility model discloses a work piece rotary disc driving mechanism for a core disc milling machine. The utility model is composed of a guide rail, a hydraulic oil cylinder, a driving gear rack, a driving gear rack, a damping device and a hydraulic station system. The utility model has the advantages of simple structure, low noise, small transmission power loss, low cost, reliable operation, etc. and has a good using prospect.
Description
The utility model belongs to the transmission mechanism of plant equipment, and specifically it is the driving mechanism that belongs to cartridge milling machine workpiece rotating disk.
The upper and lower cartridge of railway locomotive, vehicle is the car body part of locomotive, vehicle and the attaching parts between the running part, in use can cause very big wearing and tearing or rhegma, need often processing to repair, its process is to rebuild with machining tool after the repair welding again.Existing processing method is to revolve with lathe to repair, its shortcoming is: thus since cartridge location difficulty on the lathe cause lathe tool on cartridge, look for the benchmark difficulty cause processing dimension be difficult to guarantee, because lathe tool is that hilted broadsword processing cartridge working (machining) efficiency is very long very low process time, working strength of workers is very big.Change the backward state in the current cartridge process, just should adopt milling mode to process cartridge, milling mode processing processing cartridge has advantages such as working (machining) efficiency height, crudy height, labour intensity are little, and very vast potential for future development is arranged.But the manufacturing of dish milling machine has certain degree of difficulty, Here it is: because Milling Process is workpiece rotating disk of design on milling machine, cartridge is held on the rotating disk, the rotation of the rotating drive cartridge by rotating disk, cartridge milling cutter in rotating process is carrying out milling to cartridge, processing is promptly accused and is finished after cartridge rotates a circle, needs according to Milling Process, require cartridge to want turn around the most slowly in 7～10 minutes, low like this rotating speed has caused certain degree of difficulty for the design of cartridge milling machine, if adopt common ways of deceleration to have power loss big, the transmission noise is big, problems such as the many and component wear of driving parts is serious, because the problem that slowly runs of rotating disk can not get solving well, also influenced the application of milling mode in cartridge processing.
The purpose of this utility model provides the driving mechanism of the workpiece rotating disk that is used for the cartridge milling machine that a kind of power loss is little, driving parts is few, component wear is little, the kind of drive is simple, running noise is low, maintenance is easy, manufacturing expense is low, to overcome the deficiencies in the prior art.
The purpose of this utility model can realize by following structure.The utility model is a kind of drive unit of change rectilinear motion into rotatablely moving that adopts hydraulic technique, it is made up of guide rail, hydraulic jack, driving tooth bar, travelling gear, damping unit and Hydraulic Station system, main points of the present utility model are: have one to overlap the guide rail that is installed on the workpiece rotating disk main spindle box, cylinder component is installed on guide rail, cylinder component by cylinder body, piston, piston rod, sealing ring, cylinder cap, tooth bar, guide rail slipper, form.In the push rod front portion of oil cylinder or the cylinder bucket outside of oil cylinder tooth bar is installed, tooth bar is led along guide rail movement by guide rail, the rack and pinion engagement, when oil cylinder promotes the tooth bar motion, the rack drives gear rotates, finish by straight line running and turn to the process that rotatablely moves, the workpiece rotating disk main shaft that just can drive milling machine of the transmission by transmission mechanism has rotated again.Because the self-lock ability difference of oil cylinder and the gap of transmission device, the workpiece rotating disk has a reverse play when making milling, and the effect of damping unit is to eliminate the reverse play of workpiece rotating disk to the additional brake force of workpiece rotating disk main shaft.Damping unit is divided into the damping pressure generation device, brake pad and dampened disk.When milling machine cuts, the pressure that is produced by the damping pressure generation device promotes brake pad, brake pad is compressed be installed in the dampened disk on the main shaft, make the dampened disk brake force of having given main shaft, (brake force is less than the driving force of main shaft) is because the effect of brake force just can be eliminated the reverse play of workpiece rotating disk.
The utility model compared with prior art has advantages such as drive mechanism is simple, rotational noise is low, the transmission power loss is little, cost is low, reliable, is particularly suitable for the transmission condition of low rotation speed large torque cartridge milling machine.
Accompanying drawing is given except an embodiment of the present utility model, further specifies concrete structure of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the left view of structural representation of the present utility model,
Fig. 3 is a damping unit work schematic diagram of the present utility model,
In conjunction with Fig. 1～2, on guide rail 1, be mounted with oil cylinder 2, oil cylinder 2 is made up of cylinder bucket 3, piston 4, piston rod 5, front end housing 6, back cylinder cover 7, sealing ring 8, the cylinder bucket be externally-arranged with tooth bar 9, tooth bar 9 moves along guide rail 1, tooth bar 9 and gear 10 engagements.
In conjunction with Fig. 3,11 is damping oil cylinders among the figure, the 12nd, be installed on the main shaft 13 dampened disk, and the 14th, brake pad.
The utility model is the low-speed big workpiece rotating disk driving mechanism that is used for the cartridge milling machine, have advantages such as drive mechanism is simple, rotational noise is low, the transmission power loss is little, cost is low, reliable, so promotion prospect is wide.
