Description
Technical field
The utility model relates to the control circuit of guide screw rod-type automatic tapping machine, particularly a kind of duty control that realizes automatic tapping machine by gauge tap.
Background technology
Make internal thread tapping, tapping is often used in nut, it is screwed in the part that is used for playing the role of fastening with bolt or screw rod, progress and development along with society, require also more and more higher to screw thread with nut, must make the nut will the occuping market with high precision screw, yet the quality of equipment is not only depended in the control of accuracy of thread, also confidential relation is arranged with its operating state, the control circuit of existing guide screw rod-type automatic tapping machine all adopts the operating state of distinctive chip controls complete machine, and it is the circuit complexity not only, and cost is very high, in addition, electronic chip also exists the life-span short, shortcomings such as power consumption is big.
Summary of the invention
The purpose of this utility model provides a kind of control circuit of guide screw rod-type automatic tapping machine, can not only reduce cost by the control of simple ON-OFF control circuit realization to guide screw rod-type automatic tapping machine operating state, and stable working state.
The utility model adopts following scheme to realize: a kind of control circuit of guide screw rod-type automatic tapping machine, comprise the drive motors of guide screw rod-type automatic tapping machine and the on-off circuit of controlling this drive motors work, it is characterized in that: described on-off circuit comprises that master switch, motor that the control motor drive power supply turn-offs are just changeing gauge tap and motor reverse gauge tap.
In the utility model one examples of implementation, described control circuit further comprises first limit switch and second limit switch of guide screw rod-type automatic tapping machine lathe, described first limit switch is connected with the control end that motor is just changeing gauge tap, and described second limit switch is connected with the control end that motor reverses gauge tap.
The utility model need not by control chip by the control of gauge tap realization to guide screw rod-type automatic tapping machine duty, and circuit is simple, and cost is low and control effective.
Description of drawings
Fig. 1 is the structural representation of the utility model guide screw rod-type automatic tapping machine.
Fig. 2 is the contactor control connection schematic diagram of the utility model one examples of implementation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
In order to allow those skilled in the art better understand the utility model, here we simply introduce the structure of guide screw rod-type automatic tapping machine earlier, please refer to Fig. 1, Fig. 1 is the structural representation of the utility model guide screw rod-type automatic tapping machine, comprise support 1 and the frame 2 that is arranged on the support 1, it is characterized in that: described frame 2 is provided with a main spindle box 3, be provided with the main shaft 4 that is used for tapping in the described main spindle box 3, described main shaft 4 afterbodys are connected with driving screw 5, and described driving screw 5 is connected with nut 6 on being fixed on main spindle box 3.Described frame 2 is provided with drive motors 7, described drive motors 7 drives synchronous pulley 10 rotations coaxial with power transmission shaft 9 by belt gear 8, described synchronous pulley 10 is by driving the synchronizing wheel 12 that is fixed on the main spindle box 3 with 11 synchronously, and described synchronizing wheel 12 is by being arranged on spline 13 drive shaft 4 rotations on the main shaft 4.The rotation of main shaft drives the driving screw rotation of being fixed in the main shaft afterbody among the figure, driving screw will move up and down at the nut that is fixed on the main spindle box with the fixing pitch T of revolution, move up and down with fixing pitch thereby drive main shaft, realize the high accuracy tapping processing of screw thread.
In order to realize control to guide screw rod-type automatic tapping machine operating state, as shown in Figure 2, the control circuit of guide screw rod-type automatic tapping machine, comprise the drive motors of guide screw rod-type automatic tapping machine and the on-off circuit of controlling this drive motors work, it is characterized in that: described on-off circuit comprises that master switch QS, motor that the control motor drive power supply turn-offs are just changeing gauge tap KM1 and motor reverse gauge tap KM2.In order to realize the control under the different conditions, present embodiment further comprises the first limit switch K1 and the second limit switch K2 of guide screw rod-type automatic tapping machine lathe, described first limit switch is connected with the control end that motor is just changeing gauge tap, and described second limit switch is connected with the control end that motor reverses gauge tap.
Below in conjunction with Fig. 2 the duty of present embodiment is described further, is noted that here the sub-complete machine work of present embodiment can be divided into three kinds of states, comprise crawl state, single cycle state, automatic recurrent state.
At the crawl state, lathe is realized crawl adjustment function, is just changeing the lathe start button SA1 of gauge tap KM1 by controlling motor, and machine tool chief axis 4 is realized being rotated in the forward, the beginning tapping; Unclamp start button SA1, machine tool chief axis 4 stops; The lathe crawl moves to the second limit switch K2, and machine tool chief axis 4 is auto-reverse, and screw tap withdraws from workpiece; Lathe falls back on original position, and lathe quits work.
At the single cycle state, lathe is realized the single duty cycle function, presses lathe start button SA1, and machine tool chief axis 4 is realized being rotated in the forward, the beginning tapping; Unclamp start button SA1, machine tool chief axis 4 keeps just changeing state; The lathe crawl moves to the second limit switch K2, and machine tool chief axis 4 is auto-reverse, and screw tap withdraws from workpiece; Lathe falls back on original position, and lathe quits work.
In automatic recurrent state, lathe realizes repeating automatically duty cycle function, presses lathe start button SA1, and machine tool chief axis 4 is realized being rotated in the forward, the beginning tapping; Unclamp start button SA1, machine tool chief axis 4 keeps just changeing state; The lathe crawl moves to the second limit switch K2, and machine tool chief axis 4 is auto-reverse, and screw tap withdraws from workpiece; Lathe falls back on original position first limit switch K1 action, and machine tool chief axis 4 just transfers to automatically to be changeed, and repeats continuous operation.
Here what deserves to be mentioned is that also comprise the urgency that connects control motor reverse switch in present embodiment and move back button SB1, by the anxious button SB1 that moves back, workpiece is withdrawed from machine tool chief axis 4 counter-rotatings, gets back to original position until main shaft under the arbitrary duty of lathe, lathe quits work.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
