Technical scheme: for achieving the above object, a kind of rigid tapping device of the present utility model, comprise the motor that power is provided, the small pulley that links to each other with motor, described small pulley is connected with big belt wheel by driving-belt, big belt wheel is connected with spline housing by first key, spline housing is connected with main shaft by spline, main shaft is connected with tooth rule by second key, tooth is advised with pattern by being threaded, main shaft is installed in the box body hole by protheca and back cover, pattern is installed on the cover board, and cover plate is fixed on the support, and described support has a hole, be provided with pair of bearings in the hole, the spline housing outer surface is provided with raised step, and spline housing carries out axial limiting by bearing inner race and big belt wheel, and bearing is by the cover plate axial limiting.
As preferably, described tooth rule are together rotated with main shaft, are static element with tooth rule by the pattern that is threaded.
As preferably, be provided with the dish of posting a letter in the middle part of the described main shaft, the top of casing is provided with noncontacting switch.
As preferably, described noncontacting switch has two.
Beneficial effect: a kind of rigid tapping device of the present utility model, owing to only use a motor as power source, therefore have the characteristics of simple in structure, dependable performance, the saving energy, be particularly suitable for various building-block machines processing internal and external threads and use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, a kind of rigid tapping device of the present utility model, comprise the motor 2 that power is provided, the small pulley 1 that links to each other with motor 2, small pulley 1 is connected with big belt wheel 11 by driving-belt 3, big belt wheel 11 is connected with spline housing 13 by first key 12, spline housing 13 is connected with main shaft 15 by spline, main shaft 15 is connected with tooth rule 7 by second key 8, tooth rule 7 and pattern 9 are by being threaded, tooth rule 7 usefulness pressing plates 6 and screw are locked, main shaft 15 is installed in casing 19 holes by protheca 18 and back cover 14, pattern 9 is installed on the cover plate 5, and cover plate 5 is fixed on the support 4, and support 4 has a hole, be provided with pair of bearings 10 in the hole, spline housing 13 outer surfaces are provided with raised step, and spline housing 13 carries out axial limiting by bearing 10 inner rings and big belt wheel 11, and bearing 10 is by cover plate 5 axial limitings, main shaft 15 middle parts are provided with the dish 20 of posting a letter, and the top of casing 19 is provided with two noncontacting switches 21.
In the present embodiment, because big belt wheel 11 is connected by key or spline respectively with spline housing 13 and main shaft 15, therefore big belt wheel 11 rotates a week, main shaft 15 rotates a week simultaneously, are static elements, do not rotate owing to pattern 9 simultaneously, therefore tooth rule 7 are forced to move axially, and make main shaft 15 move a pitch simultaneously, the formation compound motion-and be screw (the spline cylindrical of main shaft 15 endwisely slips along the spline endoporus of spline housing 13 simultaneously).The size of pitch depends on the tooth distance of tooth rule 7 and pattern 9 screw threads, therefore, changes the tooth rule 7 and pattern 9 of different pitch, can process different thread.
The dish 20 of posting a letter is equipped with at the middle part of main shaft 15, two noncontacting switches 21 are housed on the top of casing 19, when main shaft 15 work feeds put in place, the noncontacting switch 21 on the left side was felt the dish 20 of posting a letter, noncontacting switch 21 posts a letter, and notice drive motor 2 oppositely, main shaft 15 returns; When main shaft 15 is return when putting in place, the noncontacting switch 21 on the right is felt the dish 20 of posting a letter, noncontacting switch 21 is posted a letter, and notice drive motor 2 stops, main shaft namely quits work.Two noncontacting switches 21 all can axially carry out distance adjustment along main shaft 15, with the impulse stroke of control tapping.
Front portion at main shaft 15 is equipped with screw tap 17 by spacer shell 16, is used for the screwed hole of processing parts; Also can screw die be installed in the front portion of main shaft 15 and connect handle and screw die, be used for the external screw thread of processing parts.The pitch of screw tap 17 or screw die will be advised 7 identical with the pitch of pattern 9 screw threads with tooth.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
