Embodiment 1

[0018] As shown in Figure 1, the support cylinder body 6 is a cylindrical structure, and its upper and lower ends are respectively provided with a top cover 9 and a base 7. The center of the top cover 9 is provided with a central hole, and the support rod 1 is sleeved on the body 6 The bobbin can move up and down, and its upper end is a support head 8 extending from the center hole of the top cover 9 for contact with the workpiece. The base 7 is fixed with a reducer bracket 5, and the reducer bracket 5 is equipped with a DC motor 16, DC The motor 16 and the reducer 13 are assembled in a shaft type. The output shaft end of the reducer 13 is equipped with a hollow thread head 12 to form a linkage mechanism. The thread head 12 and the nut 4 of the jacket form a thread pair that can move up and down. The upper end of 4 is fixedly connected with the switch contact 2 through the insulating pad to form the switch of the control circuit of the DC motor 16. The electrode positioning screw ...

Embodiment 2

[0024] According to Fig. 3, the precision electric control stroke support cylinder is assembled with a shaft combination of the motor 16 and the reducer 13, and the output shaft end of the reducer 13 is equipped with a wire end 12. During operation, the motor 16 drives the speed reducer 13 to rotate, thereby driving the thread head 12 to rotate. The thread head 12 drives the thread mother 4 to move up and down according to the guide pin 20. That is, screw drive. The upper end of the nut 4 is equipped with a support rod 1, and drives the support rod 1 and the sliding rheostat 19 to move up and down. The sliding rheostat 19 is installed on the lower eaves of the nut 4, the reducer seat 5 is processed with a horizontal groove, and the sliding head of the sliding rheostat 19 is inserted. In the horizontal groove. When the nut 4 is raised and lowered, the horizontal groove moves the sliding head, and the resistance value of the sliding rheostat 19 changes accordingly. The control circu...

Embodiment 3

[0030]This system can also use the form of current overload to control the rise of the support rod. The specific working principle is: the motor 16 moves, and when the support head 8 at the upper end of the support rod 1 contacts the workpiece, the load of the motor 16 increases, and the current of the motor 16 When the current reaches the set value, the control circuit is turned on, the motor 16 is powered off, and the components stop moving, that is, the start and stop of the motor are controlled by collecting the change of the motor current.

Abstract

The present invention discloses an electrical pressure actuating support method and an electrical precision support cylinder. Wherein, the support cylinder is a hollow structure. The hollow structure is divided into an upper section and a lower section and provided with a vertically moving support rod and an electrical elevator assembly. A traveling clearance is arranged between the support rod and the electrical elevator. Both ends of the clearance, viz. bottom of the support rod and top of the electrical elevator are respectively arranged with a switch contact to form a control circuit switch for the electrical elevator. The clearance is changed based on relative displacement between the support rod and the electrical elevator until they contact each other to switch on the control circuit of the electrical elevator, stop the elevator assembly and realize support. The present invention rejects complex oil pressure control system, has the advantages of no pollution, small size, simple structure, lower cost, high efficiency, accurate and reliable control and flexible support. The pressure actuating mechanism of the same size can get electrical pressure 200% to 300% higher than oil pressure.

Description

Technical field [0001] The invention relates to an electric pressure execution support method and a precision electric support cylinder, in particular to a mechanical processing tooling equipment technical field of electric support cylinders, thrust cylinders, tension cylinders, rotating cylinders, connecting rod compression cylinders, etc., belonging to machining tooling Equipment technology field. Background technique: [0002] At present, the support cylinders used in the machining process are basically spring ejection type, air ejection type, and hydraulic ejection type. Thrust cylinders, pull cylinders, rotating cylinders, and connecting rod compression cylinders currently do not have electric structures. [0003] The known patent CN2425226, an improved hydraulic floating support cylinder, is also a structural improvement of the hydraulic ejection type support cylinder. [0004] The hydraulic support cylinder mainly has the following shortcomings and defects: (1) Because the...
