Embodiment Construction
[0013] A trajectory generator, including a paintbrush 1, a pen cover 2, a sleeve 3, a spring 4, a connecting piece 5 and a connecting rod 7.
[0014] The paintbrush 1 is inserted into the pen case 2 in close fit. There is a boss on the outer edge of the pen case 2. One end of the pen case 2 passes through the sleeve 3. The pen case 2 and the sleeve 3 form a clearance fit. The inner edge of the sleeve 3 is stuck on the outer edge of the pen case 2. On the boss, the other end of the sleeve 3 is threadedly connected with the connecting piece 5, and a spring 4 is installed in the sleeve 3, the upper end of the spring 4 is pressed against the lower end of the pen case 2, and the lower end of the spring 4 is pressed against the upper end of the connecting piece 5, There is a mounting hole 6 at the lower end of the connector 5, and the connecting rod 7 passes through the mounting hole 6, so that the trajectory generator can slide along the connecting rod 7, so that the distance betwee...

A trail generator comprises a drawing pen, a pen socket, a sleeve, a spring, a connecting part and a connecting rod. The drawing pen is tightly inserted into the pen socket in a matched mode, a boss is arranged on the outer edge of the pen socket, one end of the pen socket penetrates through the sleeve, and the pen socket is in clearance fit with the sleeve. The inner edge of the sleeve is clamped on the boss on the outer edge of the pen socket, and the other end of the sleeve and the connecting part are connected together through threads. The spring is installed in the sleeve, the upper end of the spring abuts against the lower end of the pen socket, and the lower end of the spring abuts against the upper end of the connecting part. An installing hole is formed in the lower end of the connecting part, the connecting rod penetrates through the installing hole, and after the position of the trail generator is determined, locking is performed through a set screw. The drawing pen is installed on the trail generator, so that the motion trail curve of a linkage mechanism is drawn on a drawing board in real time; in the using process, the trail generator can be installed at different positions of the linkage so that different linkage motion trail curves can be drawn vividly and visually, and a student can more deeply master the motion characteristics of the linkage mechanism for achieving preset trails.
Description
technical field [0001] The present invention relates to a trajectory generator. Background technique [0002] The teaching and demonstration experiment platform of planar linkage mechanism has been widely used in various colleges and universities. When the kinematic characteristics of the predetermined trajectory are realized, the connecting rod curve cannot be drawn in real time, which is not intuitive and not easy for students to understand. Contents of the invention [0003] The purpose of the present invention is to provide a trajectory generator. The present invention designs a trajectory generator for the above deficiencies. A paintbrush is installed on the trajectory generator, which can draw the linkage motion trajectory curve in real time on the drawing board. , The trajectory generator can be installed on different positions of the connecting rod, so as to draw different connecting rod motion trajectory curves, the image is intuitive, so that students can more d...
