Description

A kind of hardware workpiece processing unit (plant)
Technical field
The present invention relates to hardware manufacture fields, and in particular to a kind of hardware workpiece processing unit (plant).
Background technology
Five metalworkings are exactly by raw material metal, are processed into respectively by drawing or sample with the machinery such as lathe, milling machine, drilling machine The part of kind various kinds, in process, grinding wheel can generate a large amount of metallic dust and high temperature with metal works Rapid contact Metal fillings if these metallic dusts cannot be handled timely, if fallen into operated implement, is often made operated implement Into damage, this is highly detrimental to the progress of five metalworkings, not only increases processing cost, also reduce working efficiency.And add The metallic dust generated during work easily sucks body by operating personnel, and high-temperature metal bits are easily splashed to operating personnel, right The health of operating personnel impacts.
Invention content
The invention is intended to provide a kind of hardware workpiece processing unit (plant), to solve metallic dust pair when existing hardware workpiece is processed The problem of processing impacts.
In order to achieve the above objectives, basic technology scheme of the invention is as follows:A kind of hardware workpiece processing unit (plant), including machine Frame is connected with lateral supporting table in the middle part of rack, drive shaft is rotatably connected in rack, sliding tooth is fixed in drive shaft Wheel, the upper and lower both sides of drive gear are engaged with symmetrically arranged transmission gear, and transmission gear has been fixedly and coaxially connected endless All gear goes back sliding sleeve in drive shaft and is connected to lateral mandril, and the upper and lower both sides of mandril are equipped with to be meshed with partial gear Tooth, the both ends of mandril have been fixedly connected with air bag, and air bag is fixed in rack, and U-shaped limiting plate, limit are equipped in the middle part of supporting table The outer openings of position plate two sides, the medial and lateral on limiting plate base are open, and the inside of supporting table and limiting plate is equipped with wind Road, air bag are connected with air duct, and the dust collecting trough of annular is equipped on the outside of supporting table, and disposal box, dust collecting trough and collection are equipped with below supporting table Dirt case connects, and is fixedly connected with cutting wheel in drive shaft, cutting wheel is located at the top on the inside of limiting plate.
The principle of this programme is:During practical application, the support construction of rack as a whole provides installation for other parts The frame of support, the work top that supporting table is processed as hardware workpiece, the power input that drive shaft is processed as hardware workpiece, The transferring member of drive gear and transmission gear as power, partial gear and bridgeware of the mandril as power, air bag conduct Metallic dust processing cleaning power source, limiting plate in supporting table to hardware workpiece processing carry out position restriction and The separation of metallic dust, metal fillings, opening, air flue are used for the flowing and guiding of air bag output gas flow, and dust collecting trough, disposal box are used for The collection and guiding of metallic dust, metal fillings, cutting wheel are used for the processing of hardware workpiece.It is slidably socketed top on the driving shaft Bar, the tooth on the symmetrical transmission gear in the upper and lower both sides of drive gear, mandril, the upper and lower both sides of mandril and transmission gear are same The partial gear of step rotation forms continuous dual direction drive mechanism, and drive gear rotation drives two transmission gears to synchronize in the same direction Rotation, two transmission gears are located at the upper and lower both sides of mandril partial gear during rotating synchronously alternately are engaged with mandril Mandril is driven to slide laterally.Opening on limiting plate is symmetrically divided into disconnected two parts centered on the middle part on base, should Two parts connect respectively with the air bag at mandril both ends and air duct.Mandril slide during wind from side air sac pressing to homonymy It supplies gas in opening on road, limiting plate, air-flow is pneumatically sent to metallic dust, the metal fillings in the supporting table of the side by opening The dust collecting trough of homonymy, the air bag synchro-draw of mandril opposite side is in the air duct of homonymy.Negative pressure is formed in opening on limiting plate, it will Metallic dust and metal fillings that hardware workpiece processing generates are pumped in the surface of supporting table, avoid metallic dust loss, metal fillings It splashes.The metal powder that is generated can be synchronized in this way during hardware workpiece processing is carried out in two parts of supporting table Dirt, the pneumatic discharge of metal fillings and pneumatic absorption so that metallic dust loss, metal fillings will not will not rest in supporting table The processing of hardware workpiece is influenced in supporting table.
The advantages of this programme is:1st, this programme can carry out metallic dust, metal fillings while hardware workpiece is processed Collection is handled, and can effectively avoid the processing of metallic dust, metal fillings the remaining influence hardware workpiece on work top;2nd, this programme The discharge and suction of metallic dust, metal fillings can be carried out in motion process in the both ends bi-directional synchronization of work top, avoids gold Belonging to dust loss influences the running of other parts and causes harmful effect to operator's health.
Preferred embodiment one, as a kind of improvement of basic scheme, on the dust collecting trough side wall opposite with limiting plate outer openings Electromagnet is respectively and fixedly provided with, partial gear is connected on mandril in the electric power loop of electromagnet.Setting can by electromagnet in this way During top rod driving air bag carry out metallic dust, metal fillings attraction so that metallic dust, metal fillings can comprehensively, Thoroughly enter dust collecting trough, when partial gear is engaged with mandril, and mandril is driven to slide, direction one is slidably advanced positioned at mandril The electromagnet of side is powered, and the metallic dust in supporting table is blowed to the dust collecting trough of the electromagnet side of energization by mandril extruding gasbag Interior, electromagnet promotes the movement of metallic dust and the movement of metallic dust is oriented to.
