Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission modules, in particular to a modular assembled rocker motion device. Background Art

[0002] In non-standard designs, it is often necessary to intermittently input power from the front and transmit it to the rear part that is staggered or has a certain center distance parameter. Based on the characteristics of non-standard designs, traditional design thinking generally solves the above situation by increasing the amount of non-standard components, such as incorporating special transmission mechanisms to participate in transmission.

[0003] Based on the application of the above-mentioned traditional technology, the addition of non-standard components undoubtedly creates a certain redundancy in the design of the entire non-standard device. First, the non-standard components are special designs, and their specific parameters, transmission coefficients and other design aspects need to be formulated and calculated by the staff themselves, which increases the workload; second, the application of non-standard components only involves non-standard devices of current specifications; if the non-standard device is improved accordingly in the subsequent period, the parameters of the non-standard components also need to be changed accordingly; based on this, the production process and assembly process and process of the non-standard components must be recalculated and set relative to the existing ones, which is relatively cumbersome;

[0004] To this end, a modular assembled rocker motion device is proposed; the device is used to solve the problem of the above-mentioned traditional technology, that is, to perform corresponding modular adaptation of the double-end transmission of the intermittent staggered shafts and meet the existing standardized design concept.

[0007] In the above implementation mode: the stroke of the linear degree of freedom is set to be adjustable; it is used to adapt to different transmission environments, self-adjust the device, and thus meet the corresponding transmission requirements.

[0011] In one embodiment, a coupling is installed at one end of the transmission shaft away from the cam.

[0012] In the above embodiment: the coupling is responsible for connecting the external power parts.

[0013] In one embodiment, a hinge shaft is hingedly connected to the outer surface end of the rocker arm, and the hinge shaft is hingedly connected to the frame.

[0014] In the above embodiment: the hinge shaft locks the degree of freedom of the rocker arm to one, thereby preventing it from having an unpredictable transmission trajectory.

[0015] In one embodiment, a sliding groove that slidably cooperates with the docking arm is provided on the outside of the rocker arm, and the rocker arm and the docking arm are detachably connected.

[0016] In the above implementation mode: Based on the above, the stroke of the linear degree of freedom is set to be adjustable; it is used to adapt to different transmission environments, self-adjust the device, and thus meet the corresponding transmission requirements.

[0030] In this solution, the stroke of the linear degree of freedom is adjustable to accommodate external non-standard components of different sizes or transmission requirements;

[0031] At the same time, the output mechanism 4 takes over the linear degrees of freedom, performs staggered displacement, and performs work externally.

[0032] In some specific embodiments of this application, please refer to Figures 1-2 : In this embodiment, the intermittent mechanism 2 preferably includes a transmission shaft 201 and a cam 203 rigidly matched with the transmission shaft 201, the cam 203 is in contact with the rocker arm 204, and realizes linear freedom in the form of intermittent drive; the rocker arm 204 drives the output mechanism 4 through the docking arm 3.

[0034] For details, please refer to Figure 2 , the cam 203 in the figure is a roller cam, and the rocker arm 204 is in direct contact with the cam 203 through a bearing to realize eccentric shaft transmission, thereby realizing swinging and intermittent cyclic linear freedom;

[0035] It should be noted that, in this specific embodiment, the cooperation between the cam 203 and the rocker arm 204 is not limited to the above-mentioned roller cam, nor is it limited to Figure 3The inner cam form shown; based on actual use requirements, the cam 203 can also be disassembled and replaced with other forms to achieve conventional cam forms such as cylindrical cams, disc cams or top cams; it is generally modular, based on the relevant parameters of the intermittent transmission, such as uniform speed, uniform acceleration or the operation requirements of obtaining any expected running trajectory;
