Abstract
The utility model discloses an indexing plunger control mechanism in order to achieve precise motion control of an indexing plunger in the prior art. The indexing plunger control mechanism comprises a machine frame, an index plate and an indexing plunger, wherein the index plate and the indexing plunger are mutually matched and arranged on a main shaft, and the machine frame is provided with a spring driving the indexing plunger to be inserted into the index plate. The indexing plunger control mechanism is characterized in that the main shaft is provided with a cam, the indexing plunger goes in and out of an indexing hole in the index plate in the axial direction through an electromagnetic valve, a convex edge is arranged in the middle of the indexing plunger, the position beside the curved surface of the cam and the front axial position and the rear axial position of the convex edge are provided with a cam limit switch, an indexing shaft advance limit switch and an indexing shaft retreat limit switch respectively, and the cam limit switch, the indexing shaft advance limit switch and the indexing shaft retreat limit switch are all connected with the electromagnetic valve. The three switches are connected with a controller of the electromagnetic valve, advance and retreat of the indexing plunger are controlled through induction of the three switches, retreat of the indexing plunger is achieved by means of the electromagnetic valve, and insertion of the indexing plunger is achieved by means of the spring.
Description
Technical field
The utility model relates to a kind of positioner of workpiece.
Background technology
Dividing head be mounted on milling machine for workpiece is divided into any equal portions machine tool accessories, utilize calibrated dial ring and vernier, alignment pin and index dial and change gear, index pin inserts and in the index hole of index dial, realizes the fixing of angle under the effect of spring, the workpiece being installed on top or chuck is divided into arbitrarily angled, circumference can be divided into any equal portions, auxiliary lathe utilizes various difform cutters to carry out the processing work of the positive tooth wheel of the positive tooth of various ditch groove ﹑ wheel ﹑ spiral ﹑ Archimedes spiral cam etc.And the precision maneuver of realizing index pin is also the vital task of indexing mechanism.
Utility model content
The utility model is intended to provide a kind of index pin controlling organization, to solve the problem that realizes the accurate action control of index pin in prior art.
Index pin controlling organization in this programme, comprise frame, index dial on the main shaft cooperatively interacting and index pin, frame is provided with the spring that orders about index pin insertion index dial, it is characterized in that: main shaft is provided with cam, index pin by solenoid shaft to turnover the index hole on index dial, index pin middle part is provided with convex edge, the curved surface side of cam is respectively equipped with the both sides, axial front and back of convex edge the cam limit switch being all connected with magnetic valve, dividing spindle carry limit switch and the dividing spindle limit switch of giving up the throne, dividing spindle carry limit switch closure in the time that index pin inserts index hole, the dividing spindle limit switch closure of giving up the throne in the time that index pin exits index hole, cam limit switch closure in the time that index dial rotation makes index hole depart from dividing spindle, the front end that dividing spindle inserts index hole is provided with pressure sensor.
Three switches are connected with the controller of magnetic valve, control the advance and retreat of index pin by the induction of three switches, exiting of index pin relies on magnetic valve to realize, and the insertion of index pin relies on spring to realize, and pressure sensor can judge whether index pin reality inserts index hole.
Further, the force side of index pin and magnetic valve is hinged by cylindrical void.That can avoid bringing after magnetic valve direction of action and index pin direction of motion deviation is improper stressed, has also facilitated the handling of equipment.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
Reference numeral in Figure of description comprises: index dial 1, index pin 2, magnetic valve 3, frame 4, on index dial, be provided with index hole 11, cam 12, index pin is provided with convex edge 21 and cylindrical void 22, is also fixed with cam limit switch 41, dividing spindle carry limit switch 42 and the dividing spindle limit switch 43 of giving up the throne in frame.
Embodiment mono-is (part-structure does not illustrate in the drawings) substantially as shown in Figure 1: index pin is in axial sliding connection in frame, the spring that connects index pin and frame orders about index pin and inserts index dial, index hole form fit on front end and the index dial of index pin, the application of force axle of the cylindrical void that the rear end of index pin is provided with and magnetic valve is hinged, and the push-pull effort that magnetic valve produces orders about index pin axially-movable.
On the main shaft of index dial, be fixedly welded with cam, the middle part of index pin is welded with annular convex edge, dividing spindle carry limit switch closure in the time that index pin inserts index hole, the dividing spindle limit switch closure of giving up the throne in the time that index pin exits index hole, cam limit switch closure in the time that index dial rotation makes index hole depart from dividing spindle, the front end that dividing spindle inserts index hole is provided with pressure sensor, be connected with the controller of magnetic valve, controller is provided with the indicator lamp that shows pressure sensor stress, and the indicator lamp described in the time that index pin inserts index hole lights.
The present embodiment can move according to following principle in certain condition: under state, index pin inserts index hole under spring action conventionally, and now dividing spindle carry limit switch closure and magnetic valve are failure to actuate; Exit index hole when starting index pin after magnetic valve, now index dial can be rotated, cam limit switch can perception cam in rotary course; Cam limit switch can judge after index hole rotates a circle gets back to original position, and now magnetic valve stops action, and index pin inserts index hole under spring action.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
