Description

Technical Field

[0001] The utility model relates to the field of cams, in particular to a hydraulic cam adjusting mechanism. Background Art

[0002] In existing production technology, some equipment needs to perform continuous high-speed reciprocating motion, such as the thread pulling device of a sewing machine. However, the speed of the gas rod structure in reciprocating motion is limited, and equipment damage or defective products often occur due to speed problems. In order to quickly make a certain action reciprocate, people often use some hydraulic cam devices to complete complex movements.

[0003] The existing hydraulic cam device is connected to the output shaft interface end of the hydraulic drive device of the cam through the hydraulic drive device, selects a cam of suitable structure, and connects the actuator to the cam. When the cam rotates, the actuator performs rhythmic reciprocating motion along the outer structure of the cam.

[0004] The existing hydraulic cam device has extremely high stability in movement because its driving device is a hydraulic driving device. However, during the movement, because the position where the cam is connected to the output shaft of the hydraulic driving device is a fixed point, its movement is fixed and cannot be adjusted due to changes in the environment. When the movement path of the actuator changes, the center point of the cam structure cannot change accordingly, and this can only be solved by replacing the cam. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing hydraulic cam mechanism cannot change the central position of the cam connection port.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a hydraulic cam adjustment mechanism, including a hydraulic drive device, a cam and an actuator, the hydraulic drive device is connected to the cam through a pin structure, the cam is slidably connected to the actuator through body contact, an adjustment mechanism is provided inside the cam, and an adjustment groove corresponding to the shape of the adjustment mechanism is provided inside the cam.

[0007] As an improvement, the adjustment mechanism includes a transverse adjustment mechanism, a longitudinal adjustment mechanism and an adjustment shell, and the transverse adjustment mechanism and the longitudinal adjustment mechanism are both located in the adjustment shell.

[0008] As an improvement, the transverse adjustment mechanism includes a transverse threaded rod, a transverse slider and a transverse auxiliary rod, the threads of the transverse auxiliary rod and the transverse threaded rod both pass through the transverse slider, the transverse threaded rod and the transverse auxiliary rod are both connected to the adjustment shell through bearings, the bearings pass through the side walls of the adjustment shell, and the transverse auxiliary rod and the transverse threaded rod are parallel to each other.

[0009] As an improvement, the longitudinal adjustment mechanism includes a longitudinal threaded rod passing through the transverse slider, a translation slider located at both ends of the longitudinal threaded rod, and a longitudinal auxiliary rod parallel to the longitudinal threaded rod. The thread of the longitudinal threaded rod is provided with a longitudinal slider, and the longitudinal auxiliary rod passes through the translation slider, the longitudinal slider and the transverse slider. The interior of the adjustment shell is provided with a translation groove corresponding to the translation slider, the longitudinal threaded rod passes through the translation slider, and the longitudinal threaded rod and the transverse threaded rod are perpendicular to each other.

[0010] As an improvement, the sides of the transverse threaded rod and the longitudinal threaded rod are provided with screwdriver sockets, one side of the longitudinal slider is provided with an output shaft interface corresponding to the output shaft of the hydraulic drive device, and the output shaft of the driving device is connected to the output shaft interface through a pin structure.

[0011] As an improvement, a bayonet through hole corresponding to the screwdriver bayonet is provided inside the cam, and a screwdriver bayonet groove parallel to the translation slide groove is provided inside the cam.

[0012] The advantage of the utility model over the prior art is that the device adjusts the position of the output shaft interface through the lateral adjustment mechanism and the longitudinal adjustment mechanism of the adjustment mechanism, so that the axis of the cam changes, thereby achieving the purpose of changing the motion trajectory of the cam, and in turn indirectly adjusting the motion trajectory of the actuator.
