Description
Technical field
The utility model discloses a kind of workbench combination of bearing ring turning digital control lathe, belong to the bearing ring turning digital control lathe technical field.
Background technology
Existing bearing ring turning digital control lathe has been accelerated operating rate for improving working (machining) efficiency, and thus, the front and back of workbench work positioning accuracy will be because of before fast and then make limited block be subjected to impacting to cause locating bad.For addressing this problem, domestic general employing now adds near switch meets and discusses, but because of near the effecting reaction distance of switch greatly, reaction sensitivity is not high, the positioning accuracy of workbench is not high all the time, easily causes workpiece processing dimension error, the defect rate height.In addition, domestic employing near switch, only can produce reaction to metal signal, human body is after running near switch, lathe still can continue processing, is prone to accidents, security performance is not high.
The utility model content
In order to address the above problem, the utility model provide a kind of can be in the workbench combination of the high bearing ring turning digital control lathe of hi-Fix under the operation fast and security performance.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of workbench combination of bearing ring turning digital control lathe, comprise and cooperate the planker that is installed on the guide rail, the upper fixed of planker front end is equipped with the workbench of band knife rest platform, the guide rail rear is provided with the hydraulic cylinder that drives planker, this hydraulic cylinder links to each other with Programmable Logic Controller by magnetic valve, described planker rear end is equipped with the foot piece of band regulating block, guide rail tail end left side is equipped with the control valve of control hydraulic cylinder hydraulic fluid flow rate, and the knob on the control valve is corresponding with the driving lever position on the regulating block; Right side, guide rail rear end is equipped with the limit switch that links to each other with Programmable Logic Controller, and right side, planker rear end is equipped with faller, and the faller rear end is equipped with adjusting screw(rod), and this adjusting screw(rod) is corresponding with the contact position on the limit switch.
Described hydraulic cylinder is fixed in the middle of the guide rail tail end by fixed head, the right side, rear end of foot piece is equipped with set screw, this set screw is corresponding with the position of meeting and discussing on being installed in fixed head, and set screw with meet and discuss when touching mutually, adjusting screw(rod) also touches mutually with contact.
After the utility model adopts such scheme, when the cutter on being installed in the knife rest platform is about near workpiece, driving lever on the regulating block can hook the knob on the control valve, drive knob, after knob turns over certain angle, control valve will reduce the fuel delivery of hydraulic cylinder, planker is become at a slow speed by fast moving move, and be normal cutting speed this moment; When this cutting is finished soon, adjusting screw(rod) touches the contact on the limit switch, limit switch transmits signal immediately gives Programmable Logic Controller, Programmable Logic Controller is just given an order, allow magnetic valve stop immediately to hydraulic cylinder forward fuel feeding, and give the reverse fuel feeding of hydraulic cylinder rapidly, workbench is had a break after finishing cutting at one time like this, with regard to the original position of fast return at once, the cutting at one time task is just accused and is finished like this.
In a word, the utility model can reduce the impact of workbench to limited block significantly under moving fast, make the each positioning accuracy unanimity of workbench, thereby guaranteed accurate to dimension, greatly reduces defect rate; Belong to microswitch because of limit switch simultaneously, reaction sensitivity is good, security performance is high, no matter be metal signal or human body, in case run into the contact of limit switch, limit switch will transmit signal immediately gives Programmable Logic Controller, Programmable Logic Controller is just given an order after obtaining signal, makes numerically controlled lathe stop the carrying out of process-cycle.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the workbench combination of the utility model bearing ring turning digital control lathe, comprise and cooperate the planker 2 that is installed on the guide rail 15, the upper fixed of planker 2 front ends is equipped with the workbench 17 of band knife rest platform 1, guide rail 15 rears are provided with the hydraulic cylinder 8 that drives planker 2, this hydraulic cylinder 8 links to each other with Programmable Logic Controller 19 by magnetic valve 20, and this is the common structure of the workbench combination of existing bearing ring turning digital control lathe.
The improvement of this case is: planker 2 rear ends are equipped with the foot piece 3 of band regulating block 7, and guide rail 15 tail ends left side is equipped with the control valve 6 of control hydraulic cylinder 8 hydraulic fluid flow rates, and the knob on the control valve 65 is corresponding with driving lever 4 positions on the regulating block 7; Right side, guide rail 15 rear end is equipped with the limit switch 14 that links to each other with Programmable Logic Controller 19, and right side, planker 2 rear end is equipped with faller 16, and faller 16 rear ends are equipped with adjusting screw(rod) 10, and this adjusting screw(rod) 10 is corresponding with contact 13 positions on the limit switch 14.
Further setting as this case, hydraulic cylinder 8 is fixed in the middle of guide rail 15 tail ends by fixed head 12, the right side, rear end of foot piece 3 is equipped with set screw 9, this set screw 9 is corresponding with 11 positions of meeting and discussing on being installed in fixed head 12, and set screw 9 with meet and discuss 11 when touching mutually, adjusting screw(rod) 10 also touches mutually with contact 13, (contact 13 and meet and discuss 11 touch in advance simultaneously adjust).Contact 13 and meet and discuss and touch 11 time makes the location of workbench 17 more accurate, has also reduced the impulsive force of 17 pairs of limited blocks of workbench simultaneously, and limit switch 14 has been played the certain protection effect, has prolonged the service life of limit switch 14.
Operation principle of the present utility model is as follows:
After clamping workpiece is correct, have a signal and send to Programmable Logic Controller 19, Programmable Logic Controller 19 just orders magnetic valve 20 that hydraulic oil is sent into hydraulic cylinder 8 after receiving signal, utilize piston rod to promote planker 2 by hydraulic cylinder 8 pistons from original position fast moving (because the workbench 17 of band knife rest platform 1 is fixedly mounted on the planker 2, so planker 2 mobile is certain to drive workbench 17 and moves together) forward; When the cutter 18 on being installed in knife rest platform 1 is about near workpiece, driving lever 4 on the regulating block 7 can hook the knob 5 on the control valve 6, driving knob 5 rotates, after knob 5 turns over certain angle, control valve 6 will reduce the fuel delivery of hydraulic cylinder 8, planker 2 is become at a slow speed by fast moving move, be normal cutting speed this moment; When this cutting is finished soon, set screw 9 is touched and is met and discussed 11, adjusting screw(rod) 10 touches the contact 13 on the limit switch 14 simultaneously, limit switch 14 transmits signal immediately gives Programmable Logic Controller 19, and Programmable Logic Controller 19 is just given an order, and allows magnetic valve 20 stop immediately to hydraulic cylinder 8 forward fuel feeding, and rapidly to hydraulic cylinder 8 reverse fuel feeding, workbench 17 is had a break after finishing cutting at one time like this, and with regard to the original position of fast return at once, the cutting at one time task is just accused and finished like this.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
