Tolerance fitting and technical measurement are very important for mechanical majors - a technical basic course, skills course and application course . It is an important technical requirement in the design drawings of mechanical parts, and it is also an important component of the static and dynamic geometric accuracy of mechanical products. With the development of science and technology and the improvement of production level, higher and higher requirements have been put forward for the geometric accuracy of mechanical products. Geometric accuracy has formed an independent technical discipline and has been favored by knowledgeable people in academia and engineering technology circles. People attach great importance to it.
This series of devices is based on the actual requirements of design engineers for precision design, combined with the actual teaching situation and teaching object conditions, and has carefully developed a set of teaching products that combine theory with practice. It is suitable for parts design, testing and inspection teaching in mechanical and electrical majors in full-time high schools, staff middle schools, vocational middle schools, higher vocational colleges and undergraduate colleges.

vocational skills comprehensive integrated tr*ning virtual Simulation system: The model
in the software can be rotated 360°, enlarged, reduced, and translated. It is equipped with universal interactive buttons: return, home page, and help. There are prompts during all virtual simulation tasks, and the software automatically checks the box after completing a task. There are experimental tasks 1 and basic three-dimensional above the tool library. (When the model is rotated, the XYZ space coordinate icon automatically follows the rotation.) A. Plane and three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - building models (drag and drop in the tool library The model is put into the three-projection plane system, and the projection is automatically displayed. There will be a prompt when the selection is wrong) - Change the posture (change by clicking the up, down, left and right arrows) - Select the projection (enter the answer interface, select the three-dimensional projection map completed at this time among the 6 items) ) B. Cutting three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - building the model (drag the model in the tool library into the three-projection plane system, and automatically display the projection) - marking the projection situation (as a three-dimensional projection icon Determine, select the corresponding label symbol in the 14 blank columns) C. Intersecting three-dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) - digging holes (select any digging model, at this time, you will be able to dig holes in the XYZ space coordinates Select any surface, the model will be switched at the same time, and a coordinate slider will appear. According to the displacement of the slider, the model will appear with a corresponding section plane) - aperture change (select 1-4 apertures) - rear through hole - select projection (enter the answer interface) , select the three-dimensional projection image completed at this time among the 8 items) 2. Assembly A, assembly assembly: The experimental steps are divided into experimental tasks (text prompt tasks)-select the assembly model (8 models are optional)-assembly assembly Body (select the tool library model according to the selected model and drag and drop to combine) - Sectioning the combined body (you can select any surface in the XYZ space coordinates, the model is switched at the same time, and a coordinate slider appears. According to the displacement of the slider, the model appears Corresponding section plane)—Select the side projection (enter the answer interface and select the correct side projection among the 3 items based on the known front and horizontal projections) B. Combination picture reading: The experimental steps are divided into experimental tasks (text Prompt task)—Select the combination section view (8 types of pictures are av*lable)—Build the combination model (select the tool library model according to the selected model and drag and drop the combination)—Section the combination (you can select any surface in the XYZ space coordinates, The model is switched at the same time, and a coordinate slider appears. According to the displacement of the slider, the model appears with a corresponding section plane) - Select the left view (enter the answer interface, select the correct left view among the 3 items based on the known m*n view and top view) View) 3. Assembly A, mechanical transmission mechanism : 8 types of mechanisms (worm gear, rack and pinion, screw transmission, out-of-plane meshing gear, in-plane meshing gear, space spur bevel gear, belt drive , ch*n drive) optional , after selecting, the model will appear in the toolbar. Drag and drop the model freely to combine it. After the combination is completed, the model can be operated. Each mechanism comes with an introduction, video demonstration, and drawing method. There are 6 questions in the answering interface, and each question has 4 options. B. Gear oil pump: According to the prompts, select the tool library model and gradually build the model. You can choose the introduction, drawing method, and animation principle (the internal movement principle of the model is visible) to learn. There are 2 questions in the answering interface, each with 4 options. C. Mechanical mechanism construction: 2 types of mechanisms (2-DOF robotic arm, 3-DOF robotic arm). Select the tool library model according to the prompts to gradually build the model. After the combination is completed, the model can be operated. Each mechanism comes with an introduction and video demonstration. . There are 2 questions in the question-answering interface (which can only be entered after both models have been built), each with 4 options.
