Abstract
The invention relates to a cam controller with built-in shaft sleeves and a mechanical limiting function. The cam controller comprises a controller housing and a camshaft. A plurality of groups of cam components are arranged on the camshaft. Pressure springs are arranged between adjacent cam components. The cam controller is characterized in that each cam component comprises a shaft sleeve sleeved on the camshaft; an outer gear ring is arranged on the middle part of the outer surface of each shaft sleeve; cams are sleeved on the two sides of the outer gear ring on each shaft sleeve; inner gear rings are arranged on the inner surfaces of the cams, and are meshed with the outer gear ring of the shaft sleeves; dowels are arranged on the end faces of the outer gear rings of the shaft sleeves; the two ends of the dowels are extended from the two end faces of the outer gear rings; a plurality of cranked slots are formed on the end faces of the cams; and the two ends of the dowels are arranged in the cranked slots of the cams on the two sides respectively. The cams are prevented from sliding, so that the reliability of the cam controller is improved; and maximum rotating regulating variables of the cams can be limited within a certain angle, so that regulating errors or accidents are avoided.
Description
Technical field
The present invention relates to a kind of built-in axle sleeve type cam controller with mechanical position limitation, especially a kind of for the cam controller on the automation equipments such as iron and steel, metallurgy, machinery, light industry, mine and various automatic production line.
Background technology
Cam controller is the important component part of punching machine electric-controlled system processed.In a duty cycle of punching machine, the action of main and auxiliaries (particularly controlled pressure machine slide block action subsidiary engine) each operating mechanism has strict logical relation, comprises order and the shared time of action of action.The method of work for the treatment of mechanism logical relation is normally distributed 360 ° of one weeks of crankshaft rotating, makes the working cycle diagram of punching machine, and the action of each operating mechanism is controlled.Cam controller is exactly the actuator that the crankshaft rotating angle is distributed.Cam controller is installed on the axle that rotates with crankshaft-synchronous, along with the rotation of bent axle, cam controller sends corresponding signal, and electric-control system sends instruction to each operating mechanism after receiving signal, operating mechanism produces the action of regulation successively, completes a duty cycle of punching machine.
Existing cam controller is comprised of camshaft, cabinet and switch module.Some groups of adjustable cams are installed on camshaft, and every group of adjustable cam is comprised of stage clip, cam and axle sleeve.Axle sleeve is arranged on camshaft, and cam is by end face gear ring and axle sleeve engagement, and stage clip is arranged in two groups of spaces between adjustable cam.When needs are adjusted angle, only cam need to be pushed engagement after the angle that needs again and gets final product along rotating to after axial withdrawal withdraw from the gear ring engagement, this angular adjustment can be carried out in 360 ° of scopes; Thereby easily occur because of the wrong or unexpected accident that causes of regulating of installing.Can produce vibration when lathe is worked, easily cause producing between cam in the cam controller of this structure and axle sleeve and slide, the formation control angular deviation; And when the travel switch contact of cam controller inside and the friction of the cam outside, the impact that cam is subjected to frictional force also relatively the end face gear ring of axle sleeve produce slip, formation control angular deviation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of built-in axle sleeve type cam controller with mechanical position limitation is provided, avoided on the one hand the slip of cam, improved the reliability of cam controller; The maximum rotation regulated quantity of cam is limited in certain angle, avoids regulating mistake or accident causes the accident.
According to technical scheme provided by the invention, described built-in axle sleeve type cam controller with mechanical position limitation, comprise the controller case, be located at camshaft and switch module in the controller case, the multiple cams assembly is installed on camshaft, be provided with stage clip between adjacent cam pack; It is characterized in that: described cam pack comprises the axle sleeve that is set on camshaft, be provided with external toothing in the middle part of the outer surface of axle sleeve, be positioned at external toothing both sides sheathed cam respectively on axle sleeve, be provided with ring gear at the inner surface of cam, the ring gear of cam meshes with the external toothing of axle sleeve; End face at the external toothing of described axle sleeve arranges pin, and the both sides end face of external toothing is stretched out at the two ends of pin; End face at described cam is provided with a plurality of crank slots; The two ends of described pin are separately positioned in the crank slot of both sides cam.
Described switch module comprises a plurality of switches that are arranged on camshaft one side, switch of every group of corresponding installation of cam pack.
Built-in axle sleeve type cam controller with mechanical position limitation of the present invention has the following advantages: (1) has avoided the slip of cam on the one hand, has improved the reliability of cam controller; (2) the maximum rotation regulated quantity of cam is limited in certain angle, avoids regulating mistake or accident causes the accident.

Embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 6: as described in comprise controller case 1, camshaft 2, axle sleeve 3, external toothing 3-1, cam 4, ring gear 4-1, pin 5, crank slot 6, stage clip 7 etc. with the built-in axle sleeve type cam controller of mechanical position limitation.
As shown in Figure 1, the present invention includes controller case 1, be located at camshaft 2 and switch module in controller case 1; According to required control signal on described camshaft 2 how many multiple cams assemblies be installed; Described cam pack comprises the axle sleeve 3 that is set on camshaft 2, be provided with external toothing 3-1 in the middle part of the outer surface of axle sleeve 3, be positioned at the sheathed cam 4 of external toothing 3-1 both sides difference on axle sleeve 3, inner surface at cam 4 is provided with ring gear 4-1, the ring gear 4-1 of cam 4 and the external toothing 3-1 of axle sleeve 3 engagement; Be provided with stage clip 7 between adjacent cam pack, two cams 4 on axle sleeve 3 compress by stage clip 7;
As Fig. 5, shown in Figure 6, at the end face of the external toothing 3-1 of described axle sleeve 3, pin 5 is set, the both sides end face of external toothing 3-1 is stretched out at the two ends of pin 5; As shown in Figure 3, Figure 4, the end face at described cam 4 is provided with a plurality of crank slots 6; The two ends of described pin 5 are separately positioned in the crank slot 6 of both sides cam 4;
