Embodiment Construction

[0014] The specific structure and implementation mode of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The structural composition of the present invention is as figure 1 , figure 2 with image 3 shown. The improved sinusoidal acceleration cam locking mechanism consists of servo motor (1), L-shaped plate (2), support plate (3), transmission shaft (4), cam (5), incomplete bevel gear (6), cross guide rail ( 7), slide block (8), guide rail strut (9), spring (10), groove bevel gear (11), connection surface (12), boss (13). The servo motor (1) is connected with the support plate (3) by means of the L-shaped plate (2), and serves as the source power device of the locking mechanism. The transmission shaft (4) is connected with the servo motor (1), and the cam (5) and the incomplete bevel gear (6) are coaxially installed. By changing the power phase sequence of the servo motor (1), the connection between the connectin...

Abstract

The invention relates to an improved sine acceleration cam locking mechanism. The improved sine acceleration cam locking mechanism is mainly composed of a servo motor, a supporting plate, a transmission shaft, a cam, an incomplete bevel gear, a cross-shaped guide rail, a guide rail fulcrum bar, a groove bevel gear, a connecting face and the like, wherein the servo motor serves as a source power device of the locking mechanism to be connected with the transmission shaft, and the cam and the incomplete bevel gear are coaxially installed to provide power for connection and disconnection between connection faces; the cam makes contact with the surface of the cross-shaped guide rail, and by means of rotation of the cam, the cross-shaped guide rail is driven to forwards move according to a sineacceleration motion law; the guide rail fulcrum bar is installed in a cross-shaped guide rail sliding groove and is connected with a sliding block to form a guide rail assembly, and the guide rail assembly can do rectilinear motion; the groove bevel gear with a sinusoid groove is installed on the supporting plate, the guide rail fulcrum bar is tangent to the sinusoid groove all the time, and the rotation of the groove bevel gear can drive the guide rail assembly to move in the radial direction; and the connecting face is connected with the supporting plate through the cam to form a connectingface structure locked to an external connecting unit.

Description

technical field [0001] The invention relates to an improved sinusoidal acceleration cam locking mechanism. Background technique [0002] Since the 1990s, self-reconfigurable cellular robots have developed rapidly in the United States and Japan, and several self-reconfigurable cellular robots based on different connection methods have been proposed one after another. The main connection methods are pin hole type, claw type and Velcro type. The pin hole type relies on the mutual nesting of the taper hole and the taper pin to realize the connection and separation of the two connection surfaces; the hook type relies on a micro motor to drive the claw to move to realize the locking connection of the connection surface; the velcro type relies on rotation The rocker-shaped buckle is bonded to the tail of the previous unit. However, the interchangeability of the active and passive connection surfaces of these three connection methods is poor, and the processing is complicated, whi...
