The driving sleeve is engaged with the driving leading screw, the guiding rod penetrates through the upper part of the contact head plate fixed on the driving sleeve, and the regulating screw rod is engaged with the on-off switch. When the screw stroke controller controls a stroke, a plurality of circles of rotation control can be realized by designing the screw length and the thread pitch of the driving leading screw. The utility model has the advantages of simple structure and convenient fabrication.
Description
The present invention relates to a kind of machinery automatic controller, specifically a kind of journey controller.
In industrial production, the Stroke Control of swirl gear is to use comparatively general technology.Adopt more prevailing mechanical control method to have following three kinds at present: 1. adopt two places control.Promptly set up position limit switch respectively at the two-end-point in stroke zone.2. adopt individual pen formula revolution control, as LK4 type master controller.Its shortcoming is the control of individual pen formula, and promptly controlled quentity controlled variable in most cases must be slowed down on former transmission basis within a circle, and need add one or more speed reducer could realize.3. adopt worm and gear to slow down, utilize the worm gear output shaft to carry out many swirl gear controls again, its shortcoming is the fine setting poor performance, worm and gear processing relative complex.
The purpose of this invention is to provide and a kind ofly can make mechanism simplifying, change rotation motion into straight-line spiral journey controller, overcome above-mentioned shortcoming of the prior art.
The objective of the invention is to realize by following technological scheme:
A kind of spiral journey controller comprises housing, turn-screw, rigid bearing in the composition, its improvements are that it also has transmission top board and on-off switch; The transmission top board is meshed with turn-screw, and on-off switch is two, lays respectively at the both sides of turn-screw.
The above line range controller, described transmission top board is made up of drive sleeve and contact top board, and drive sleeve is meshed with turn-screw, and the contact top board is fixed on the drive sleeve.
Above line range controller, the both sides of described turn-screw respectively have one to adjust screw rod, and each is adjusted screw rod and is meshed with an on-off switch.
The above line range controller also has two guide rods, and is all parallel with turn-screw, a top of passing the contact top board, and another passes the bottom of two on-off switches.
Above line range controller, described on-off switch have fixed contact, fixed contact fixed plate, moving contact, moving contact clamping plate, bearing pin, Returnning spring, contact base; Fixed contact fixed plate, bearing pin, Returnning spring are installed on the contact base, moving contact is installed in moving contact clamping plate upper end, the middle part of moving contact clamping plate has axis hole to cooperate with bearing pin, its underpart is corresponding with contact top board position, Returnning spring is extension spring, and two ends are separately fixed on fixed contact fixed plate and the moving contact clamping plate.
The above line range controller, described adjustment screw rod is meshed with the inner hole thread of the contact base of on-off switch.
Adopt the spiral journey controller of this structure when the control stroke, helix length and the pitch by the design turn-screw to realize multi-turn revolution control, thereby can save speed reduction gearing, in use also can carry out the continuous stepless adjusting to stroke by regulating the adjustment screw rod.The utility model is simple in structure, and is easy to make.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 2;
As can be seen from the figure this journey controller mainly is made up of drive part and on-off switch.Drive part comprises turn-screw 2, drive sleeve 4, contact top board 7, guide rod 5,6, adjusts screw rod 8.Guide rod and adjustment screw rod are two, and they parallel with turn-screw.The middle part of drive sleeve 4 is enclosed within on the turn-screw 2 and has internal thread to be meshed with turn-screw, contact top board 7 is fixed on the drive sleeve 4, the top of contact top board 7 is porose, guide rod 5 therefrom passes, the two ends of turn-screw 2 are installed on the housing 1 of journey controller by bearing 3, and are connected with the transmission system of institute control apparatus.On-off switch partly comprises two on-off switches, lay respectively at the both sides of turn-screw 2, each on-off switch is fixed on one and adjusts on the screw rod 8, and guide rod 6 is all passed in the bottom of two on-off switches, makes on-off switch can move along guide rod 6 when adjusting screw rod 8 rotations.Each on-off switch comprises fixed contact 9, fixed contact fixed plate 10, moving contact 11, moving contact clamping plate 12, bearing pin 13, Returnning spring 14, contact base 15.Fixed contact 9, moving contact 11 are separately fixed at the top of fixed contact fixed plate 10 and moving contact clamping plate 12, fixed contact fixed plate 10 is fixed on the contact base 15, there is pin-and-hole at moving contact clamping plate 12 middle parts, it matches with bearing pin 13 on being fixed on the contact base, on the corresponding position on the top of fixed contact fixed plate and moving contact clamping plate, spring shaft 16 is arranged, drawn Returnning spring 14 between them, contact base 15 is enclosed within to be adjusted on the screw rod 8, and its endoporus has screw thread and adjusts screw engages and fixing by nut 17.
During work, the transmission system of institute's control apparatus drives turn-screw 2 and rotates, turn-screw 2 drives drive sleeve 4 and travels forward, guide rod 5 may command drive sleeve 4 do not rotate, contact top board 7 on the drive sleeve 4 contacts with the bottom of moving contact clamping plate 12, promote moving contact clamping plate 12 and rotate, and make the moving contact 11 on moving contact clamping plate top separate, realize outage control with fixed contact 9 around bearing pin 13.When turn-screw 2 backward rotation, contact top board on the drive sleeve 47 breaks away from moving contact clamping plate 12, Returnning spring 14 pulling force on moving contact clamping plate top make its around bearing pin 13 to back rotation, moving contact 11 contacts energising with fixed contact 9 thus.Adjust screw rod 8 contact base 15 is moved adjusting on the screw rod 8 as regulating to rotate the control stroke, fixing with nut 17 then.
Two on-off switches are arranged in the utility model, in real work, can increase to four on-off switches, be symmetrical arranged, realize multiple spot control, parts such as adjustment screw rod with matching also increase thereupon.
