The CNC table is one of the important accessories in CNC equipment. Its main function is to assemble two CNC worktables to form an XY numerical control workbench to realize positioning and linkage of two coordinates. The numerical control worktable is composed of base, guide rail, ball screw nut pair, motor seat and wire. Bar support mechanism, slide plate, travel switch, protective cover and other components. After the assembly of the CNC machine table of the thread-turning lathe, the movement is required to be smooth and easy. When the skateboard is running to different positions, the no-load driving force is the same, the linearity of the sliding movement, the parallelism of the sliding plane and the moving direction, the sliding surface of the sliding plate and the bottom surface of the base Parallelism must meet the specified technical specifications. Pipe thread lathe disassembly and assembly should be carried out conscientiously, and each part to be removed should be arranged and registered. The assembly should be carried out in the reverse order of disassembly, and the CNC table should be carefully tested to make the assembly accuracy and motion accuracy match. Claim. Teaching and training meetings, classroom teaching; traditional projectors are not easy to carry. In school classrooms, due to the naughty students, projectors are not safe in the classroom and are easily damaged by students. The portability of micro projectors makes up for the teaching vacancies. In the future, teachers will give lectures. You only need to store the data in the projector to show it to students for teaching, saving the trouble of textbooks and handwriting with pens and chalks. portable projector for teaching,portable projector education,portable classroom projector,projector for teachers Shenzhen Happybate Trading Co.,LTD , https://www.szhappybateprojector.com
1) Pipe thread lathe tool prepares one CNC working table, one set of dial gauge and magnetic watch stand, one flat ruler (300mm), two adjustable spanners, two wooden handles and one set of hex wrenches.
2) Step 1 Remove the positioning pin and the connecting screw of the table and the guide rail slider and the nut holder, and remove the table (slide).
2 Check the contact surface of the guide rail on the workbench, the parallelism between the contact surface of the nut holder and the work surface and record.
3 Check the parallelism between the guide rail and the ball screw and record.
4 Remove the positioning pin and screw that the ball screw bracket is connected to the base, remove the ball screw nut pair, loosen the coupling, and remove the drive motor.
5 Check the parallelism between the contact surface of the ball screw bracket on the base and the guide rail.
6 Remove the positioning pins that are connected to the base by the rolling guides, and remove the rolling guides.
7 Check the flatness of the mounting surface of the rolling guide on the base and the straightness of the guiding surface and record:
8 Clean the parts that have been removed and prepare for assembly.
9 Install the rolling guide on the base and check the installation accuracy. The accuracy value before the removal should be achieved.
10 Install the ball screw assembly on the base and check the parallelism between the lead screw and the guide rail. The accuracy value before disassembly should be achieved. The pipe thread lathe is then fitted with a drive motor to tighten the coupling.
11 Install the table on the rail slider and connect the screw nut holder to the table.
12 After installation, check the geometric accuracy.
During the assembly process, the parallelism of the sliding plane and the bottom surface of the base, the straightness of the sliding of the sliding plate, the parallelism of the sliding plane and the moving direction, and the parallelism between the ball screw and the guide rail must be carefully checked, and the measurement accuracy before assembly. Compare. If the accuracy of the pipe thread lathe after assembly exceeds the allowable range, it should be re-adjusted.
It can be seen that when diagnosing and repairing more complicated equipment such as numerical control equipment, the following points should be made:
1 It is necessary to collect and digest relevant materials in advance and make adequate preparations. On this basis, the disassembly, maintenance steps and precautions are formulated.
2 Strictly follow the requirements of the relevant materials (drawings, instructions, etc.) and pay attention to the data in the data. Pipe thread lathe data is often an important basis for guiding equipment maintenance. For example, the torque used to tighten the screws is based on technical data.
