The tool holder structure control system and working principle of CNC wood lathe machine:
In the operation and application of CNC lathes, the electric tool rest is an important part. Its rational use in operation can bring a lot of convenience to the operator. So what are the structural control systems and operating principles of the electric tool rest? The following are Clarification on the above:
1. Tool holder structure of CNC wood lathe machine：
The economical CNC lathe tool holder is used to introduce its structure and composition. The economical CNC lathe tool holder is an automatic tool changing equipment developed on the basis of the general CNC lathe. Its function is the same as that of the general tool holder. There are four tools. Position, can clamp four different functions of the tool, the tool holder rotates 90 degrees, the tool communicates with one tool position, but the rotation of the tool holder and the selection of the tool position number are controlled by the machining program instructions.
2. Control system of CNC wood lathe machine tool holder：
The electrical control of the tool rest is mainly to control the forward rotation and rotation of the tool rest motor by controlling two communication contactors, and then control the forward rotation and rotation of the tool rest.
3. The working principle of CNC wood lathe machine tool holder：
When changing the tool, the action sequence of the tool holder is: tool holder lifting, tool holder indexing, tool holder positioning and tool holder clamping.
1). The tool holder is lifted: the tool holder can be equipped with four different tools, and the index signal is commanded by the processing program. The second is the manufacturer's planning. When purchasing machinery and equipment, you must choose the right manufacturer, which is not only a guarantee of the quality of the machine, but also a layer of security for after-sales. After the CNC system announces the tool change command, the PMC control outputs the forward rotation signal, the tool post motor forward rotation control relay KA3 is pulled in, the tool post motor forward rotation control contactor KM3 is pulled in, and the small motor 1 is recommended to rotate forward, through the flat key sleeve The coupling 2 makes the worm shaft roll over, and then drives the other worm shafts to roll over.
2). Tool holder indexing: When the end face teeth are completely disengaged, the indexing sleeve is just rotated 160 degrees, and the pin hole on the indexing sleeve at the front end of the turbine screw is just aligned with the orientation of the ball stud.
3). Tool rest positioning and clamping: the tool rest body rolls with the brush holder, when it turns to the tool number specified by the program, the PMC releases the forward rotation signal, outputs the rotation signal, the tool rest motor rotation control relay is closed, and the tool rest The motor rotates to control the contactor to pull in, the tool holder motor rotates, and the positioning pin enters the groove of the rough positioning plate under the effect of the spring for rough positioning and clamping.
