Problems solved by technology

This not only makes the whole device extremely large and complex, but also extremely expensive
Such as the kneading massager disclosed in Chinese patent document CN 102940566 A, not only the structure is extremely complicated, but also fails to give the trajectory of bionic motion; another example is the numerical control rubbing type grinding machine disclosed in Chinese patent document CN 103252709 A, then adopted 3 servo The motor, as well as the extremely complex mechanical transmission system, is bulky and expensive
From a kinematic point of view, no substantial hands-rubbing bionic device has yet been retrieved

Embodiment 1

[0024] see figure 1 A pneumatic hands-rubbing bionic device shown includes a frame (not shown in the figure), and two sets of rubbing components 10, 10' arranged on the frame.

[0025] The kneading assembly 10 includes a gear 1 rotatably arranged on the frame around the axis, and a connecting rod 2 rotatably arranged on the gear 1 through a pin shaft 3 . There is an eccentric pin hole on the gear 1, the center line of the pin hole is parallel to the axis line of the gear 1, one end of the pin shaft 3 is connected to the upper part of the connecting rod 2, and the other end is rotatably passed through the above pin hole middle. A chute 4 is provided on the connecting rod 2, and the chute 4 extends along the length direction of the connecting rod 2, and the frame is provided with a slider 5 centrally hinged on the frame for providing the guidance of the connecting rod 2, that is, the slider 5 The center positions of the two axial ends of the shaft are hinged on the frame, ...

Embodiment 2

[0034] see figure 2 Shown is a bionic device for rubbing with both hands, the difference between this bionic device and Embodiment 1 is mainly in the setting of the parts that provide the guides of the connecting rods 2, 2'. In this embodiment, the guide member 6, 6' provided on the frame is centered on the part that provides the guide of the connecting rod 2, 2', and the guide member 6, 6' is respectively arranged in the chute 4, 4' with loose fit. Among them, the circumferential outer surface of the guides 6, 6' matched with the longitudinal groove walls of the chute 4, 4' is a cylindrical surface, and the guides 6, 6' form a plane height pair with the chute 4, 4' respectively. When the double-sided rack 8 moves along the length direction to drive the gear 1 and the gear 1' to rotate, the connecting rods 2 and 2' are relative to the guides 6 and 6 on the cylindrical outer surface under the action of the pin shafts 3 and 3' respectively. 'does both linear motion and swing...

Abstract

The invention discloses a pneumatic double-hand rubbing bionic device. According to the pneumatic double-hand rubbing bionic device, only the simple parts including air cylinders, double-face racks, gears, connecting rods and sliding blocks or guiding parts are used, and the complex plane motion of simulating double-hand rubbing can be realized, wherein the centers of the sliding blocks are hinged to a machine frame or the centers of the guiding parts are fixed to the machine frame and the outer surfaces of the guiding parts are cylindrical. Rubbing tools with different functions are fixed to the lower ends of the connecting rods so that various pneumatic double-hand rubbing bionic devices with different functions can be formed. The pneumatic double-hand rubbing bionic device is extremely simple in structure, especially low in manufacturing cost, high in working reliability, and capable of meeting the requirements for the rubbing bionic devices of different industries. A striking contrast is formed between the pneumatic double-hand rubbing bionic device and other bionic devices which are huge and complex in structure and extremely high in manufacturing cost, and the pneumatic double-hand rubbing bionic device can be widely popularized and used.

Description

[0001] technical field [0002] The invention relates to a pneumatic bionic device for rubbing hands. Background technique [0003] In the innovative design of the mechanism, it is extremely difficult to imitate the movement of human hands by relying solely on the movement of the mechanism itself. Because the movement of human hands rubbing is a compound motion of linear motion and swing. Using numerical control technology to imitate the action of human rubbing is the easiest technical solution to think of. However, using numerical control technology to imitate the movement of rubbing with one hand requires at least two servo motors, which are programmed and driven by a two-axis linkage numerical control system; system control to achieve. This not only causes the whole device to be extremely large and complex, but also extremely expensive. Such as the rubbing massager disclosed in Chinese patent document CN 102940566 A, not only the structure is extremely complex, but al...
