Wood Lathe
Contents
Definition
A wood lathe consists of a bed, a tailstock installed at the end of the guide rail of the bed, a tool holder installed at the middle of the guide rail of the bed, a headstock installed at the head of the bed, a main shaft installed on the headstock, and The chuck on it, the motor installed on the headstock, and the variable speed transmission device installed on the motor shaft and the main shaft and the headstock box are characterized in that the variable speed transmission device is composed of a slave fixed on the end of the main shaft The fixed half-wheel of the variable speed triangle belt wheel, the movable half-wheel of the driven variable speed triangle belt wheel fitted on the main shaft and inserted into the fixed half-wheel, and the push-pull arm mounted on the end of the movable half-wheel with bearings are installed on the The compression spring between the push-pull arm and the headstock, the rack fixed on the push-pull arm parallel to the main shaft and sliding in the hole of the headstock, the end of the gear meshing with the rack passes through the gear shaft of the headstock, to The small shaft is installed in an open groove at the end of the gear shaft and has an eccentric wheel with a handle, a movable half wheel and a fixed half wheel of an active variable-speed V-belt wheel mounted on the motor shaft or its connecting shaft, and is mounted on the movable half The compression spring and the safety between the wheel and the motor shaft or the retaining ring at the end of the connecting shaft V-belt in the belt driving and driven gear wheels formed.
Features
Structural Features
The woodworking lathe is a combined structure of the spindle box and feed box. It is suitable for processing workpieces with large diameter and short length. High-speed steel or cemented carbide tools can be used to process steel, cast iron and light alloy parts Rough and precise turning of inner hole, end face, tapered face, grooving, and cutting.
Performance Features
Woodworking lathes have excellent performance, and according to the survey, they can basically achieve "people stop without stopping and do three shifts a day." But the premise is that timely maintenance must be carried out in accordance with the instructions. And for rough turning machining, the number of knives can reach about 3, the optimized design of the transmission system greatly reduces the failure rate of the machine tool, and the specially processed gear system can transfer more damping torque to each axis so that The force is applied to protect the teeth.
Types
The lathe machines are divided into ordinary wood lathes, copying wood lathes and round bar machines.
Ordinary Wood Lathes
The workpiece is clamped in the chuck or supported between the main shaft and the tailstock for rotational movement. The turning tool is mounted on the tool holder, and the sliding box is used to move the longitudinal or horizontal feeding motion, and the turning tool can also be held against the carriage for feeding. Ordinary wood lathes are used for the processing of outer circles, end faces, grooving, and boring.
Copying Wood Lathes
The master is installed parallel to the workpiece, and the master can be fixed or rotate at the same speed as the workpiece. The tool is controlled by the master for lateral feed, and the tool holder is moved longitudinally by the action. This machine tool is divided into vertical and horizontal, single-axis and multi-axis, and is used to process the complicated shape of furniture, such as censer legs and rifle butts.
Round Bar Lathe Machines
The square wood is compressed by two pairs of feed rollers for longitudinal feed. The cutter head inside the hollow main shaft rotates at high speed, and the wood is cut into round bars through the hollow main shaft.
Applications
wood lathes are mainly used for processing various stair columns, Roman columns, table and chair legs, washbasins, wooden vases, wooden column tables, rods, wooden furniture, children's bed columns, etc. It can also process plates, stemware, cups, handles, rolling pins, flutes, flutes, cello accessories, etc. It is especially suitable for mass production of small and medium-sized woodworking enterprises, which can flexibly set the shape at any time and quickly change the processing style. In traditional lathe processing, only one product can be processed at a time. The wood lathe has double-axis, double-axis, and three-axis wood lathes, which can process two or three products at the same time, with the same size and size. The operation is simple, the drawing is convenient, and it is easy to understand. The product style of one-key conversion, no professional knowledge personnel can conduct a little training. The fully automatic CNC wood lathe can operate 2-3 sets at the same time, which greatly improves the processing efficiency, saves labor, saves money, and brings good economic benefits.
