Spindle moulder

1. Composition of spindle moulder

The bed is an integral box structure made of cast iron. Several rib plates are arranged inside the bed to ensure sufficient stiffness and strength. The fixed worktable is fastened on the bed through bolts and adjustable support sleeve. The main shaft is supported in the shaft sleeve by two thrust bearings. Rotating the hand wheel can make the shaft sleeve rise and fall with the main shaft, and the motor drives the main shaft through the belt.

The handle is used to adjust the tightness of the spindle V-belt. The handle can adjust the deflection of the main shaft, which can deflect the main shaft to any position between 0 ° and 45 ° vertically, so as to mill parts at various angles. Adjust the handle to make the spindle accurately in the vertical position. A cutter head is installed in the conical hole at the upper end of the main shaft. The upper end of the cutter head can be installed into the cantilever support on the fixed workbench as required.

The movable worktable can move horizontally along the cylindrical guide rail under the support of the bracket, so as to process the tenon and the end face of the parts. The movable workbench is also equipped with a horizontal hydraulic press, an eccentric vertical clamp, a backup plate and a limiter. In order to facilitate the loading and unloading of tools, the spindle can be fixed through the handle. The machine tool is also equipped with guide plate, control button and safety cover.

2. Spindle adjusting mechanism of spindle moulder

Spindle adjustment mechanism of single shaft end milling machine. The adjustment mechanism of the spindle is used to adjust the lifting and tilting of the spindle. The lifting mechanism of the main shaft is composed of an upper shaft seat, a lower shaft seat, a bevel gear and a bevel gear. A bevel gear is installed between the upper and lower shaft seats. The other end of the bevel gear meshed with the bevel gear is installed with a hand wheel. The bevel gear can rotate in the shaft sleeve. When the hand wheel is rotated, the bevel gear can drive the bevel gear to rotate. Because the thread on the bevel gear is combined with the thread on the shaft sleeve, it can drive the shaft sleeve to move up and down along the guide key, The guide key is fixed on the lower shaft seat through nuts. The shaft sleeve can be locked by turning the handle through the ejector rod and the ejector block. Adjusting the inclination of the main shaft is completed by the bracket, arc guide rail, adjusting plate and nut. The bracket and the lower shaft seat are connected by bolts, and the adjusting plate is fixed on the bracket by bolts. The bracket is sleeved outside the shaft sleeve and can rotate around it. The arc guide rail is fixed on the disc by bolts. When the nut moves, the bracket rotates along the arc guide rail and drives the lower shaft seat to rotate, so as to tilt the main shaft in the lower shaft seat. The degree of inclination can be indicated by the scale on the disc. It also shows the device for fixing the spindle when changing the tool. The utility model is mainly composed of a bolt installed on the lower shaft seat, a spring, a support and a handle installed on the bed.
