Description

Mortise and tenon reverse rotating platform

Technical Field

The invention relates to a machining accessory of a wood industry machine tool, in particular to a mortise and tenon reverse rotating table which is mainly used for a non-metal frame machine and can be matched with other equipment.

Background

At present, the processing modes of the wood machine tool generally adopt the following two modes: 1, when a solid wood strip is processed, a motor rotates to drive a screw to jack a pressing plate, the solid wood strip is fixed by the pressing plate, and mortise and tenon processing of a single end face is carried out; 2, when the solid wood strip is processed, the ejector rod is driven by the air cylinder to jack the pressing plate, the solid wood strip is fixed by the pressing plate, and single-end-face mortise and tenon processing and manufacturing are carried out. Above two kinds of processing methods add man-hour to wood strip both ends, all must carry out twice and fix, take place the wood strip easily and move and lead to shifting, can't carry out accurate processing, also can't once only accomplish the mortise and tenon processing of wood strip both ends.

Disclosure of Invention

The technical scheme of the invention is as follows: the utility model provides a mortise and tenon turn-over table, includes a U type reversal pedestal, 180 rotatoryss are equipped with to U type reversal pedestal intermediate frame, by installing 180 revolving cylinder drives at its tip, and 180 rotatoryss cup joint press from both sides tight work piece mesa, cup joint the limiting plate in the pivot of 180 rotatoryss both sides, can block on U nature reversal pedestal, press from both sides tight work piece mesa and be equipped with 90 rotatory air cylinders down, and the limiting plate passes through the connecting rod and connects rotatory holding down plate, rotatory holding down plate is semi-circular, and it has the slip fixed slot to open on it, is equipped with adjustable push rod in the slip fixed slot, the tip keeps in contact with pressing from both sides tight work piece mesa under the adjustable push rod. The adjustable push rod comprises a positioning push rod, a tapping thread at the middle lower part of the positioning push rod is sleeved with a locking nut, a boss is arranged on the positioning push rod, a spring is arranged above the boss and sleeved with a positioning sleeve, a positioning groove is formed in the positioning sleeve, the positioning push rod is provided with a pin hole close to the lower part of the spring and fixed through a spring pin, the other end of the positioning push rod penetrates through the positioning sleeve, the end part of the positioning push rod is a round table, and the diameter of the positioning push rod is matched with that of the positioning sleeve. In order to prevent dust from entering, a dustproof sleeve can be additionally arranged outside the positioning sleeve.

The invention has the beneficial effects that: the processing precision is accurate, production efficiency is high, general strong adaptability, because can overturn two-sided processing, the processing of both ends can one shot forming about. The workpiece is fixed by a 90-degree rotary pressing cylinder, the workpiece is placed in place on a table top of a clamped workpiece, the adjustable push rod is adjusted through a sliding fixing groove, the workpiece is positioned, the 90-degree rotary pressing cylinder presses down the fixed workpiece, when the A surface is machined, the A surface can be turned over by 180 degrees to perform B surface machining, and the 180-degree rotary cylinder returns to the original point after the machining is completed.
