Description
Technical field
The utility model relates to a kind of two drill bit driving mechanisms being applied to bench drill, is applied to beads processing.
Background technology
Beads are more and more subject to liking of people as a kind of entity product of faith, because the market space is large, the processing of current beads is also very many, in order to more efficient and have a quality process the target that beads are current enterprises, but rely on existing bench drill and can only process halfbody beads, reprocess out halfbody beads after needing reversion, such shaping efficiency is low, quality is also easily influenced.Therefore, for the problems referred to above be the utility model research object.
Utility model content
In order to solve existing technical deficiency, the utility model provides a kind of two drill bit driving mechanisms being applied to bench drill.
Of the present utility modelly to be characterised in that:
A kind of two drill bit driving mechanisms being applied to bench drill, comprise bench drill main body, the top of described bench drill main body is provided with the first rack sleeve and feeding handle, the first main shaft installing drill bit is provided with in described first rack sleeve, one end of described feeding handle and one first rotating shaft is connected, the middle part of described first rotating shaft is fixed with one first idler gear, tell the first gear and engage with the tooth bar of the first rack sleeve periphery, it is characterized in that: the bottom of described bench drill is provided with the first main shaft coaxial line and the second main shaft in order to install another drill bit, described second main shaft is installed and is connected in the second rack sleeve of bench drill lower body part, the periphery of described second rack sleeve also has rack structure, the other end of described first rotating shaft is fixed with one first gear, one end of described first gear and a chain is connected, the bench drill main body of described first gear side is hinged with one second gear, the lower hinge of described bench drill main body has one the 3rd gear, described second rack sleeve periphery rack structure engages with second idler gear be affixed on one second rotating shaft one end, the other end of described second rotating shaft is fixed with one the 4th gear, the other end of described chain walks around the first gear successively, second gear, be connected with a spring being affixed to bench drill lower body part after 3rd gear and the 4th gear.
Wherein, described 4th gear turn to the axial opposed with the first gear.。
Advantage of the present utility model: the utility model structure is simple, and it is convenient to manipulate, can be realized the move toward one another of two drill bit, thus meet follow-up beads process requirements by operation.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment side structural representation,
Fig. 2 is the structural representation of the utility model embodiment opposite side feeding handle portion.
Detailed description of the invention
Referring to figs. 1 to Fig. 2, the utility model relates to a kind of two drill bit driving mechanisms being applied to bench drill, comprise bench drill main body, the top of described bench drill main body is provided with the first rack sleeve 1 and feeding handle 2, the first main shaft 3 installing drill bit is provided with in described first rack sleeve, one end of described feeding handle and one first rotating shaft 4 is connected, the middle part of described first rotating shaft is fixed with one first idler gear 5, tell the first gear and engage with the tooth bar of the first rack sleeve periphery, the bottom of described bench drill is provided with the first main shaft coaxial line and the second main shaft 6 in order to install another drill bit, described second main shaft is installed and is connected in the second rack sleeve 7 of bench drill lower body part, the periphery of described second rack sleeve also has rack structure, the other end of described first rotating shaft is fixed with one first gear 8, one end of described first gear and a chain 9 is connected, the bench drill main body of described first gear side is hinged with one second gear 10, the lower hinge of described bench drill main body has one the 3rd gear 11, described second rack sleeve periphery rack structure engages with second idler gear 13 be affixed on one second rotating shaft 12 one end, the other end of described second rotating shaft is fixed with one the 4th gear 14, the other end of described chain walks around the first gear successively, second gear, be connected with a spring 15 being affixed to bench drill lower body part after 3rd gear and the 4th gear.
In order to ensure that two main shafts can move toward one another, what make above-mentioned 4th gear turns to the axial opposed with the first gear, thus ensures that two drill bits be installed on main shaft can be holed in opposite directions.
Specific implementation process: by swivel feeding handle, feeding handle is made to drive the first rotating shaft to rotate, first rotating shaft drives the first idler gear and the first gear to rotate again, because the rack structure of the first idler gear with rack sleeve periphery engages, thus drive active sleeve descending, and main shaft is installed in rack sleeve, so rack sleeve then drives main shaft descending; Simultaneously because the first gear rotates, the chain that so one end is connected on the first gear will be pulled, because the chain other end is connected by spring and bench drill lower body part, so chain will be rotated by the second gear, the 3rd gear driven the 4th gear, 4th gear rotates and then drives the second axis of rotation, second axis of rotation then drives the second idler gear to rotate, and the second idler gear finally drives the second rack sleeve engaged with it up, makes the second rack sleeve drive the second main shaft to rise; Finally complete the move toward one another of two drill bits.
Although specifically show in conjunction with preferred embodiment and describe the utility model; this technical scheme method and access of specific implementation is a lot; the above is only preferred embodiment of the present utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
