Cutterhead 1 back side gear train 14 is to expose in the working range of cutting, Workpiece boring or milling or ward off the groove process and cause living metal fillings, splash gear train 14 interferes with the smoothness of engaged transmission easily, have influence on what is more main tapping socket handle of a knife 11 firmly whether.

In view of this, the utility model application artificially solves aforementioned problems, grinds a kind of cutterhead power source location structure that wound is applicable to the drilling-tapping machine now.

Summary of the invention

One of the utility model purpose provide a kind of be applicable to the drilling-tapping machine and with the transferring power element protection in casing; make metal fillings no longer splash be entrained between each element of bridle joint, machining accuracy is reduced to the cutterhead power source location structure of minimum impact degree.

For reaching aforementioned purpose, a kind of drilling-tapping machine knife of the utility model dish power source location structure, comprise: one is arranged on the cutterhead of board, this cutterhead periphery equidistantly is provided with a plurality of chuck seats, respectively this chuck seat presss from both sides the handle of a knife of the binding cutter of pulling, and these cutterhead central authorities have the rotating shaft of inserting indexing case, and this indexing case is located between cutterhead and the board, this rotating shaft is passed a case lid and is linked with an index dial that is positioned at indexing case, and the one side that this index dial differs from cutterhead equidistantly is provided with a plurality of pulleys; Two contiguous pulleys and the moving portion of spiral shell bridle joint, the moving portion of this spiral shell is arranged on the driven shaft, this driven shaft one end is worn group has roller bearing to be set up on the indexing case, utilize a closure member that port is sealed, the other end of this driven shaft assembling roller bearing, pass this indexing case and link with a follower of a gear-box inside, this follower bridle joint one main wheel, this main wheel is linked on the power transmission shaft of a power source, this power transmission shaft passes a load seat that supplies aforementioned power source to set firmly, and this load seat system is covered in the openend of gear-box.

According to above-mentioned drilling-tapping machine knife dish power source location structure, have following advantage:

A comprises rotating shaft 24, pulley 33, the moving portion 34 of spiral shell, follower 42, main wheel 43 and power transmission shaft 44 even flowing elements; all be protected in indexing case 3 and the gear-box 41; process generation metal fillings no longer splash is entrained between each element of bridle joint relation, reduces to minimum to the influence degree of machining accuracy.

B is under the situation of not interfering cutterhead 2 each handle of a knife 23 running, and each actuated element distance to each other more formerly technology is little, and with regard to the loss of mechanical energy, the utility model more formerly technology has more low-loss advantage.

The specific embodiment

Fig. 2 and Fig. 3 are the embodiment that is applicable to the relevant cutterhead power source of drilling-tapping machine, and drawing shows that one is arranged on the cutterhead 2 of board 21, and these cutterhead 2 peripheries equidistantly are provided with a plurality of chuck seats 22, and respectively this chuck seat 22 presss from both sides the handle of a knife 23 of the binding cutter of pulling.

These cutterhead 2 central authorities have the rotating shaft 24 of inserting indexing case 3, this indexing case 3 is located between cutterhead 2 and the board 21, this rotating shaft 24 is passed a case lid 31 and is linked with an index dial 32 that is positioned at indexing case 3, and the one side that this index dial 32 differs from cutterhead 2 equidistantly is provided with a plurality of pulleys 33.
