The invention discloses a geography teaching model convenient for demonstration, which comprises a base. Block 1, a connecting rod 1 is movably installed on the left side of the cover block 1, the top of the connecting rod 1 is fixedly connected with a sphere 2, the surface of the connecting rod 1 is fixedly connected with a support block, and the top of the connecting rod 1 is fixedly connected with a support block. The surface is socketed with a sleeve block two at the top of the support block. The present invention achieves the effect of being able to fix the second block by setting the first connecting rod, the support block, the second block, the second connecting rod, the third sphere, the fixed block and the fixed rod, so that the second block cannot be rotated, and the The three spheres are fixed, so that the lecturer can explain without manually supporting the moon, thereby reducing the difficulty of teaching for the lecturer, making the lecturer less likely to feel tired, and being convenient for people to use.

The invention discloses an automobile brake drum robot spraying system and method. The system is based on a machine learning two-classifier automobile brake drum detection system, which can detect the position, shape and size information of the brake drum, and can judge the position of the brake drum. Whether the brake drum is missing or not, it has strong adaptability to environmental changes; the 6-dimensional torque sensor is installed at the end of the robot arm to realize manual dragging and teaching of the spraying path, which reduces the difficulty of teaching. At the same time, the teaching path based on Kalman filter is used. The optimization method can ensure the stability and efficiency of the spraying process, improve the spraying quality and equipment life; the mobile robot structure design realizes the automatic spraying control of multi-station and multi-brake drums on the premise of ensuring the movement accuracy, which improves the spraying efficiency and improves the efficiency of spraying. With less manual intervention, the entire spraying system meets the development requirements of automation and intelligence, which is conducive to the intelligent transformation and upgrading of enterprises and even the spraying industry.

Novel laser teaching equipment comprises a base, a key device, a processing device, a fragrance excitation device, a display device and a sound making device; keys are used for sending key electric signals after pressing; each recognition part comprises a sticking layer, a recognition layer and a fluorescent layer which are sequentially arranged in an overlapped manner; the processing device is used for sending a laser control electric signal, a display control electric signal and a sound making control electric signal; the fragrance excitation device comprises a plurality of laser transmitters and a plurality of fragrant liquid storage components; the laser transmitters are used for receiving and responding to the laser control electric signal and sending laser beams to the fragrant liquid storage components. According to the novel laser teaching equipment, by arranging the base, the key device, the processing device, the fragrance excitation device, the display device and the sound making device, recognition and memory abilities of children can be enhanced from three aspects of fragrance, image and sound, so that the teaching difficulty is low and the teaching effect is good.

The invention discloses a flexible self-adaptive mechanism of an angle grinder. The flexible self-adaptive mechanism comprises a first fixing board and so on, the first fixing board, a first blanking plate, a second blanking plate and a third blanking plate are connected in sequence to form a box body; a first fixing block is located between the first fixing board and a mounting base; a bush is mounted on the mounting base; a first equal height bolt is located in the bush; a cylinder is mounted at the bottom end of the mounting base and is connected with a joint; the joint is connected with a first connecting rack; a second equal height bolt is fixed with the first connecting rack; a second connecting rack is parallel to the first connecting rack and is connected with a first support board; a second support board is located under the first support board; the angle grinder is located between the second support board and a fourth blanking plate; a clamp block is located between the angle grinder and the fourth blanking plate. The flexible self-adaptive mechanism of the angle grinder enables the automatic workpiece grinding yield of a robot to be improved, enables the grinding quality to be improved, enables the service efficiency of the angle grinder to be improved, and enables the service life of the angle grinder to be prolonged.

The invention discloses a geometric teaching aid for mechanical drawing with the function of folding and storing, and relates to the technical field of mechanical drawing teaching aids, including a base, an adjustment mechanism is provided on the top of the base, and a teaching aid body is movably connected to one side of the adjustment mechanism. One side of the adjustment mechanism is slidably connected with a projection mechanism, and both sides of the top of the base are fixedly connected to side plates, and a number of cover plates are hinged on the top of the base, and the cover plates are attached to the side plates on both sides. The adjustment mechanism includes a first As for the slider, a first sliding slot is opened on the top of the base.
