For solving the problems of the technologies described above, the purpose of this utility model is the tapping rod device providing a kind of tooth machining unit, and the tapping rod device structure of this tooth machining unit is simple, and without the need to high-power servomotor and switching gear-box, cost is lower.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of tapping rod device of tooth machining unit, comprise base, support, brushless electric machine, square sleeve, tooth bar and swivel nut, described brushless electric machine is fixed on described base bottom, the bottom of described square sleeve is provided with motor connecting hole, the top of square sleeve is provided with tooth lever attachment hole, the output shaft of described brushless electric machine is connected in the motor connecting hole of square sleeve, described tooth bar is structure as a whole, this tooth bar comprises the head section set gradually from top to bottom, thread segment and rear, the rear of described tooth bar is connected in the tooth lever attachment hole of described square sleeve, the female tapped through hole of tool is provided with in described swivel nut, the thread segment of described tooth bar is provided with the external screw thread with the screw-internal thread fit of the tapped through hole of swivel nut, the thread segment of described tooth bar is arranged in the tapped through hole of swivel nut, described swivel nut is fixed on described support, described support is fixed on the upside of described base, the head section upper end of described tooth bar is provided with the tapping-head connecting hole for connecting tapping-head.
Further, the tooth lever attachment hole of described square sleeve is square hole.
Further, the cross section of the rear of described tooth bar is square.
Further, the shape of described support is " several " font.
The beneficial effects of the utility model are: the tapping rod device of tooth machining unit of the present utility model adopts brushless electric machine, and directly drive the tooth bar of integrative-structure to rotate by square sleeve, tooth bar rises or declines under the screw-driven effect of the tapped through hole of its thread segment and swivel nut, realizes the tapping action of the tapping-head be connected in tooth bar head section.The brushless electric machine that the utility model adopts has that volume is little, power foot, cost are not high and the advantage such as little that consumes energy, and it is more energy-conservation than high-power servomotor as power resources.And brushless electric machine volume is narrow and small, so any space can be arranged on easily, thus structure can significantly be simplified.Tooth bar of the present utility model is the integrative-structure be made up of head section, thread segment and rear, and the structure of tooth bar can realize being connected with the convenient of brushless electric machine, swivel nut and tapping-head, thus makes whole tapping rod device structure simple, without the need to gimbal structure.The utility model drives the action of tooth bar by brushless electric machine, whole device can be arranged on tooth machining unit very easily, tapping can be carried out at any angle, without the need to spare parts such as high-power servomotor and switching gear-boxes, thus significantly reduce board and tooth bar cost, the energy at least over half can be saved.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figures 1 to 4, a kind of tapping rod device of tooth machining unit, comprise base 1, support 2, brushless electric machine 3, square sleeve 4, tooth bar 5 and swivel nut 6, described brushless electric machine 3 is fixed on bottom described base 1, the bottom of described square sleeve 4 is provided with motor connecting hole 41, the top of square sleeve 4 is provided with tooth lever attachment hole 42, the output shaft of described brushless electric machine 3 is connected in the motor connecting hole 41 of square sleeve 4, described tooth bar 5 is structure as a whole, this tooth bar 5 comprises the head section 51 set gradually from top to bottom, thread segment 52 and rear 53, the rear 53 of described tooth bar 5 is connected in the tooth lever attachment hole 42 of described square sleeve 4, the female tapped through hole 61 of tool is provided with in described swivel nut 6, the thread segment 52 of described tooth bar 5 is provided with the external screw thread with the screw-internal thread fit of the tapped through hole 61 of swivel nut 6, the thread segment 52 of described tooth bar 5 is arranged in the tapped through hole 61 of swivel nut 6, described swivel nut 6 is fixed on described support 2, described support 2 is fixed on the upside of described base 1, head section 51 upper end of described tooth bar 5 is provided with the tapping-head connecting hole 511 for connecting tapping-head (not shown).
Furtherly, the tooth lever attachment hole 42 of described square sleeve 4 is square hole.
Furtherly, the cross section of the rear 53 of described tooth bar 5 is square.
Furtherly, the shape of described support 2 is " several " font.
During work, brushless electric machine 3 drives square sleeve 4 to rotate, and square sleeve 4 drives connected tooth bar 5 to rotate again.Because the thread segment 52 of tooth bar 5 is threaded with the swivel nut 6 be fixed on support 2, thus under the effect of screw-driven, the thread segment 52 of tooth bar 5 can rise relative to swivel nut 6 or decline, thus the rear 53 of tooth bar 5 moves up and down relative to square sleeve 4, the head section 51 of tooth bar 5 also can realize moving up and down, thus the tapping-head be connected in the head section 51 of tooth bar 5 just can complete tapping action.
The brushless electric machine 3 that the utility model adopts has that volume is little, power foot, cost are not high and the advantage such as little that consumes energy, and it is more energy-conservation than high-power servomotor as power resources.And brushless electric machine volume is narrow and small, so any space can be arranged on easily, thus the structure of whole tapping rod device can significantly be simplified.Tooth bar 5 of the present utility model is the integrative-structure be made up of head section 51, thread segment 52 and rear 53, and the structure of tooth bar can realize the connection with brushless electric machine 3, swivel nut 6 and tapping-head, thus makes whole tapping rod device structure simple, without the need to gimbal structure.The utility model drives the action of tooth bar by brushless electric machine, whole device can be arranged on tooth machining unit very easily, tapping can be carried out at any angle, overcome current tooth bar tapping blind spot, shorten the allotment time, without the need to high-power servomotor, spare part such as switching gear-box and universal joint etc., save tooth bar cost, decrease board required drive, save the energy.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
