X-shaped electric fixture for cam

Abstract

The invention discloses an X-shaped electric fixture for a cam, and relates to a mechanical device. An X-shaped transmission mechanism is formed by two transmission pieces which are crossed in the middle part and only can rotate at a cross point, the cam is clamped in the middle of the upper ends of the transmission pieces, the outer ends of opening and closing parts are arranged outside a shell, clamping jaws are fixedly arranged on the outer ends of the opening and closing parts, two transmission points of transmission chains are respectively in two driven recesses, and when the distance between the two transmission points is changed, the two opening and closing parts are also changed, the two clamping jaws fixedly arranged on the opening and closing parts are also opened and closed along with the change of an included angle, a rotating motor capable of controlling a rotating angle is used for driving the cam with a designed shape to rotate so as to enable the clamping jaws to open and close according to needs, the shapes and the positions of the cam, the upper ends of the transmission pieces and the lower ends of the transmission pieces are set and adjusted, and the electric fixture meeting different requirements can be manufactured. The X-shaped electric fixture for the cam can be used for mechanical automation.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an X-type cam electric clamp. technical background [0002] Grippers are widely used in various machinery and equipment, especially in the fields of automation equipment and intelligent robots, which have a wide range of needs. [0003] Pneumatic grippers are widely used. The advantage is that the technology is mature and the price is low. The disadvantage is that the response time is slow, basically only two points reciprocate, and the movement of multiple points cannot be selected, and the service life is not ideal. [0004] There are many ways to implement electric grippers, such as using the motor to drive the screw and the forward and reverse screw to drive the nut to move to realize the opening and closing of the mechanical structure. The design disclosed in the applicant's previous Chinese patents CN201015847Y and CN1164392C has a more complicated structure, and The design disclosed...

Problems solved by technology

[0003] Pneumatic grippers are widely used. The advantage is that the technology is mature and the price is low; the disadvantage is that the response time is slow, basically only two points reciprocate, and the movement of multiple points cannot be selected, and the service life is not ideal.

[0004] There are many ways to implement electric grippers, such as using the motor to drive the screw and the forward and reverse screw to drive the nut to move to realize the opening and closing of the mechanical structure. The design disclosed in the applicant's previous Chinese patents CN201015847Y and CN1164392C has a more complicated structure, and The design disclosed in CN101439479B relies on the movement of the nut, the speed of movement is slow, the range of movement is limited, and the response time is slow. In the case of fast opening and closing, the response speed is not ideal
