Description
Technical field
The present invention relates to machinery processing apparatus, more particularly, to a kind of guide rail processing unit (plant).
Background technology
At present its low production efficiency of guide rail Drilling operation and precision low so that poor product quality, such as bore mode at present
Typically there are two kinds：Method one, movable workbench, workpiece are installed on the table, this institution requests workbench length is more than
Workpiece length, requires lathe length just longer simultaneously, at least the twice of workbench, the therefore larger of lathe bed and workbench
Afterwards, lead to added cost, difficulty of processing increases, and the precision of workpiece is not easy to ensure；Method two, fixed using workpiece, plus
The tool spindle in work hole moves, and such mechanism size reduces, but because tool spindle is moving, to the structural rigidity of lathe with regard to phase
High to comparing, the specification that increase rigidity certainly will increase guide rail can reach, so added cost to equipment.
And in process, single workpiece operation break-down carries out substep and processes, and specifically, a workpiece is bored
Hole, needs to bore location hole, boring, reaming, also the two ends of device to hole carry out chamfering, and each operation is entered using different process equipments
Row processing；This requires repeatedly to carry out multiple bearing to workpiece, and machining accuracy is low, hand labor intensity is big；The whole brill of guide rail
Hole machined low production efficiency, machining accuracy are low.In order to meet the market demand, inevitable requirement manufacturer increases machinery and puts into and personnel
Put into, production cost is high.
When to guide rail Drilling operation, because the length of guide rail is longer, some longer guide rails reach more than 5 meters, guide rail
On have row's installing hole, to install hole machined when, need, to guide rail, usually using cylinder, guide rail to be compressed, if
Simply single cylinder can make guide rail upwarp guide rail compression, when particularly guide rail has just started processing, or guide rail is being processed
Finally during several work step, guide rail does not fix to clamp so that the position of guide rail shifts in region completely into workbench, with
When not firm to the fixation of guide rail.
Because the length of guide rail is longer, some longer guide rails reach more than 5 meters, typically have one sending into end to guide rail
Row's running roller supports, and sends end in guide rail and has pull bar to pull out, and does not therefore have running roller to support sending end, is so easily caused
Guide rail sag bent, causes the mobile dimensions length to workpiece to control inaccurate.And guide rail needs the silk of corresponding length in processing
Bar sliding guides, because screw mandrel length is long, the zone line of screw mandrel can be sagging, leads to produce whipping, work during screw mandrel rotation
Can only the moving at a lower rate of platform.Lead to screw mandrel to deform after life-time service, thus causing that movement velocity is low, precision simultaneously
Difference.
And in drilling equipment, generally by Motor drive, and drill bit is the bearing block being arranged on rotation by fixture
On, and fixture is connected with the output shaft of motor by fixing axle, shaft coupling, or connected by way of belt pulley, so tie
Structure is complex, takes up room big, leads to the overall volume of machine larger.
Therefore in the course of processing of guide rail, in prior art, there are a lot of problems, lead to high cost, the body of process equipment
Long-pending huge, the machining accuracy of long guideway is low, corresponding short lead rail, and the error of its borehole accuracy and position dimension all can increase.
Content of the invention
The invention solves the problems that the problem that above-mentioned prior art exists, provide a kind of guide rail processing unit (plant), improve working (machining) efficiency
And crudy.

The leading screw and nut mechanism driving；Right boring machine and right beveler are separately mounted on right cross slide way, right boring machine and right chamfering
The rear end of machine connects motor-driven leading screw and nut mechanism；This structure is to carrying out drilling and chamfering on the right side of guide rail workpiece, simultaneously right
The left side of guide rail workpiece carries out reaming and chamfering, and right boring machine and right beveler differ two stations, are therefore to enter simultaneously
Row four procedure is processed, and improves working (machining) efficiency；And the reaming on the left side and chamfering are differed with the drilling and chamfering position on the right and lead
A station on rail workpiece, as long as the distance (i.e. a station) by mobile for a guide rail workpiece pitch-row, you can carry out next
Step processing.
The guide pad of limited location side about workpiece is wherein fixed on supporting table, guide pad has pilot hole, workpiece
Upper surface is higher than the upper surface of guide pad；The compact heap being close on workpiece, compact heap are provided with the piston rod of compression cylinder
Lower pressure surface be close to the surface of workpiece and guide pad respectively；This structure has row's compression cylinder to be pressed on workpiece down simultaneously,
Play the positioning action of more firm stable, and when workpiece is not completely into supporting table, workpiece do not move to below compression cylinder,
It is pressed under compression cylinder on guide pad, compact heap contacts the upper surface to workpiece and plays the effect of workpiece pressing.
Wherein pull bar is fixed on sliding seat by fixed seat, and sliding seat is arranged on rail plate, and rail plate is installed
On support base, support base is installed motor-driven screw mandrel, screw mandrel is connected on sliding seat by feed screw nut；On support base
Screw mandrel is installed and supports cylinder, screw mandrel supports and is provided with, on the piston rod of cylinder, the support block being supported on screw mandrel；This structure is led to
Cross and support the support block on cylinder to be supported on below screw mandrel, prevent screw mandrel sagging, such that it is able to avoid screw mandrel whipping, the rotation of screw mandrel
