Description
Technical field
The utility model relates to a kind of penknife drive mechanism.
Background technology
As shown in Figure 1, hob head 1 is fixed on housing 2 prior art by hobboing cutter fixed mount and left support, and handle 3 is connected with hob head 1, drives hob head 1 to rotate around its center when handle 3 rotates; Hobboing cutter 5 is fixed on hob head 1 again by hobboing cutter steady pin 4, hobboing cutter 5 can be rotated around hobboing cutter 5 Pivot Point Center on hobboing cutter fixed mount, because hobboing cutter 5 has gear, hob head fixed block 6 also there is corresponding gear, so, when hob head 1 rotates, the gears meshing on the tooth on hobboing cutter 5 and hob head fixed block 6, hobboing cutter 5 is rotated, thus blade on hobboing cutter 5 can chip pencil; But because the hob head fixed block 6 of this type of penknife is fixed on housing 2 motionless, during chip, the number of turns that penknife handle 3 needs turn can be many, the rotating speed of hobboing cutter 5 is also comparatively slow, so chip efficiency is relatively low.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of penknife drive mechanism that penknife chip efficiency can be made to improve.
For solving the problem, the technical solution adopted in the utility model is: penknife drive mechanism, comprise and being connected and the hob head of synchronous axial system with penknife handle, described hob head is provided with hobboing cutter and hobboing cutter gear, hobboing cutter gear is external tooth, described penknife handle is positioned to be connected with the outer ring of hob head connected position one with the travelling gear of penknife handle synchronous axial system, described travelling gear be bevel gear and profile of tooth towards hob head side, the outer ring of described hob head is positioned at the position corresponding with hobboing cutter gear and is provided with a rotatable hobboing cutter driven wheel and the diameter of hobboing cutter driven wheel is greater than the diameter of hobboing cutter gear, described hobboing cutter driven wheel be bevel gear and profile of tooth towards travelling gear side, described hobboing cutter driven wheel and equal diameters relative with travelling gear profile of tooth, an idle pulley is at least provided with between described hobboing cutter driven wheel and the profile of tooth of travelling gear, described idle pulley coordinates with the profile of tooth of hobboing cutter driven wheel and the profile of tooth of travelling gear respectively, described hobboing cutter driven wheel is also provided with internal tooth and corresponding with the external tooth position of hobboing cutter gear and cooperatively interact.
Preferably, two idle pulleys can be provided with between described hobboing cutter driven wheel and the profile of tooth of travelling gear.
Preferably, described penknife handle and travelling gear can be formed in one.
Preferably, described penknife handle and travelling gear can also pass through assembly and connection.
Preferably, described penknife handle and hob head are by being threaded.
The beneficial effects of the utility model are: the rotation of the utility model hobboing cutter driven wheel accelerates the geared speed of hobboing cutter gear and hobboing cutter driven wheel internal tooth, thus accelerates the rotation of hobboing cutter, therefore improve the chip efficiency of penknife, and structure is simple.

Detailed description of the invention
The utility model is further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 2, described penknife drive mechanism, comprise and being connected and the hob head 2 of synchronous axial system with penknife handle 1, penknife handle 1 described in the utility model is threaded connection with hob head 2, be threaded and install and manufacture homogeneous phase to convenient, described hob head 2 is provided with hobboing cutter 3 and hobboing cutter gear 4, hobboing cutter gear 4 is external tooth, described penknife handle 1 is positioned to be connected with the outer ring of hob head 2 connected position one with the travelling gear 5 of penknife handle 1 synchronous axial system, described travelling gear 5 be bevel gear and profile of tooth towards hob head 2 side, the outer ring of described hob head 2 is positioned at the position corresponding with hobboing cutter gear 4 and is provided with a rotatable hobboing cutter driven wheel 6 and the diameter of hobboing cutter driven wheel 6 is greater than the diameter of hobboing cutter gear 4, described hobboing cutter driven wheel 6 be bevel gear and profile of tooth towards travelling gear 5 side, described hobboing cutter driven wheel 6 and equal diameters relative with travelling gear 5 profile of tooth, as shown in Figure 3, an idle pulley 7 is at least provided with between described hobboing cutter driven wheel 6 and the profile of tooth of travelling gear 5, described idle pulley 7 coordinates with the profile of tooth of hobboing cutter driven wheel 6 and the profile of tooth of travelling gear 5 respectively, described hobboing cutter driven wheel 6 is also provided with internal tooth and corresponding with the external tooth position of hobboing cutter gear 4 and cooperatively interact.
The utility model does not do concrete restriction to the number of idle pulley 7, when preferentially selecting, two idle pulleys 7 can be provided with between described hobboing cutter driven wheel 6 and the profile of tooth of travelling gear 5, not only can not additionally increase too many cost but also the rotation of penknife handle 1 can be made relatively lighter;
Penknife handle 1 described in the utility model and travelling gear 5 can be formed in one, one-body molded easily manufactured, easy for installation; Also can pass through assembly and connection, after penknife handle 1 and travelling gear 5 wherein have one to be damaged, only need to change damage, need not change simultaneously, decrease maintenance and repair cost comparatively speaking; Concrete condition can be determined according to specific needs.
During use, penknife handle 1 rotates, hob head 2 rotates with penknife handle 1 together, hobboing cutter gear 4 now on hob head 2 just starts to revolve round the sun around the center of hob head 2, and constantly engage with the internal tooth of hobboing cutter driven wheel 6 simultaneously, therefore hobboing cutter gear 4 also starts rotation, thus drives hobboing cutter 3 to start to rotate, and now just starts chip; Meanwhile, when penknife handle 1 rotates, travelling gear 5 drives the reverse of hobboing cutter driven wheel 6 by idle pulley 7, and now, the rotation of hobboing cutter driven wheel 6 accelerates the geared speed of hobboing cutter gear 4 and hobboing cutter driven wheel 6 internal tooth, thus accelerate the rotation of hobboing cutter 3, therefore improve the chip efficiency of penknife.
