Teaching aid for mechanical course teaching

Abstract

The invention relates to the technical field of a teaching aiding auxiliary device, in particular to a teaching aid for mechanical course teaching. The position fixation can be conveniently performedon relevant teaching materials; the slide falling of the teaching materials in the support plate rotating process is prevented; the use effect is good; the practicability is high; the carrying and themovement are convenient; and convenience is brought to users, so that the use reliability is improved. The teaching aid comprises a bottom plate, a driving motor, a rotating shaft, a driving chain wheel, a driven chain wheel and a chain, wherein the output end of the driving motor is provided with a transmission shaft; the chain is arranged on the driving chain wheel and the driven chain wheel ina sleeving way; two groups of shrinkage frames are arranged at the left side and the right side of the top end of the bottom plate; the teaching aid also comprises two groups of threaded rods, two groups of threaded pipes, two groups of first chain wheels, two groups of second chain wheels, two groups of transmission belts, two groups of servo motors, a connecting plate, a rotating shaft and twogroups of driving plates; a clamp plate is arranged at the bottom end of the rotating shaft; one group of transmission belts are arranged on the two groups of the first chain wheels in a sleeving way;the other group of transmission belts are arranged on the two groups of second chain wheels in a sleeving way; and the teaching aid also comprises a lifting handle.

Description

Technical field [0001] The invention relates to the technical field of teaching auxiliary auxiliary devices, in particular to a teaching aid for teaching mechanical courses. Background technique [0002] As we all know, the teaching aids used for mechanical course teaching are devices used to demonstrate the cooperative connection of mechanical equipment, so that students can understand and memorize related mechanical operating principles and structures, thereby improving the efficiency of mechanical teaching. It has been widely used in the field of teaching aids; the existing teaching aids used in the teaching of mechanical courses include the bottom plate, drive motor, rotating shaft, active sprocket, passive sprocket and chain. The top of the bottom plate is provided with a connecting groove to connect The bottom end of the groove is provided with a fixed plate, the top end of the fixed plate is provided with a rotating hole, the bottom end of the rotating shaft extends into t...

[0002] As we all know, the teaching aids used in the teaching of mechanical courses are a device used to display the matching and connection methods of mechanical equipment so that students can understand and memorize the relevant mechanical operating principles and structures, thereby improving the efficiency of mechanical teaching. It has been widely used in the field of teaching aids; the existing teaching aids for the teaching of mechanical courses include a base plate, a drive motor, a rotating shaft, a driving sprocket, a passive sprocket and a chain, and the top of the base plate is provided with a connecting groove. The bottom end of the groove is provided with a fixed plate, the top of the fixed plate is provided with a rotary hole, the bottom end of the rotating shaft extends into the rotary hole and the outer wall of the rotating shaft contacts the inner wall of the rotating hole, the top of the rotating shaft is connected with the bottom end of the support plate, and the driving The motor is installed in the connecting groove, the output end of the driving motor is provided with a transmission shaft, the driving sprocket and the passive sprocket are installed on the transmission shaft and the rotating shaft respectively, and the chain is sleeved on the driving sprocket and the passive sprocket; When using teaching aids for mechanical course teaching, the relevant teaching staff will place the mechanical equipment teaching materials above the support plate, turn on the drive motor to drive the transmission shaft set on it to rotate, and at the same time drive the drive sprocket to rotate and drive the chain to rotate relatively to drive The passive sprocket rotates and drives the rotating shaft to rotate in the fixed plate at the same time, which can drive the support plate to rotate and the mechanical teaching materials on the support plate to rotate, so that the mechanical teaching materials can be displayed in many ways to facilitate students to understand and memorize relevant knowledge; however, the existing During the use of the teaching aids used in the teaching of mechanical courses, it is found that it is inconvenient to fix the position of the relevant teaching materials, and it is easy to cause the teaching materials to slip during the rotation of the support plate, the use effect is poor, and the practicability is low; moreover, it is inconvenient Carrying and moving, causing inconvenience to users, resulting in lower reliability of use
