Description

one

The invention relates to the woodworking industry.

A circular-shaped shaped semi-automatic machine for manufacturing wooden parts is known, including a frame, a support with clamping centers, a cutting tool, a magazine with side walls and a drive.

The purpose of the invention is to expand the range of workpieces, regardless of their length, to increase the productivity of the machine, as well as to ensure that the clamping centers approach the ends of the next workpiece and precisely pre-clamp and center it.

This is achieved by mounting rails on the frame, on which the caliper is mounted with clamping centers that can be moved by means of a mechanical transmission system connected to an electric motor by means of, for example, a worm gearbox, while a crank drive rod is used as a mechanical transmission system. mechanism, and in the side walls of the store, the drive is slotted.

FIG. 1 schematically shows a semi-automatic plan; in fig. 2 shows a section along A-A in FIG. one.

The circular bevel shaped semiautomatic device contains a bed 1 with guides 2 and an inclined platform 3; the suplort 4, made in the form of a plate, moving along the guides and carrying two headstocks on it: the left drive 5 and the right 6 with centers and a cutter 7, which is a rigidly mounted console plate.

The left head 5 contains an axially moving and simultaneously rotating spike driving center, inside which, in conjunction with it, there is a needle detector centro-detector, which moves the actuator in the axial direction. The axial direction of the center and the center-digger is carried out by two successively mounted on one axis (one after the other) hydraulic cylinders.

Rights grandma 6 has a non-power center with spikes. Inside the center, in conjunction with it, there is a spring-loaded center-finder with a needle, the end of which in the static

position goes beyond the spikes. Centre

and the center finder is supported by bearings.

Store 8 is

A chute vertically mounted on frame 1 and adjustable (moved) in both vertical and horizontal planes. At the bottom of the store, a platform for basing, pre-centering and removing

it centers of the workpiece.

The caliper with clamping centers is moved, with help, to a mechanical transmission system, such as a crank mechanism 9, comprising a housing associated with a caliper in which a connecting rod finger, a connecting rod and / (crank suit, crank disk finger, the base of which is made rectangular guides placed in the groove of the crank plate; a connecting rod finger fixed with a screw; and a shaft supported on bearings in the housing and carrying a crank disk on one neck and an asterisk on the other.

The drive 10 of the caliper consists of an electric motor, a worm gear and a V-belt and chain transmission.

As a braking mechanism, bushes are used that are in alignment with the centers (left, right, motionless).

Semiautomatic works as follows.

After the storage unit 8 is filled with blanks, the semiautomatic device is turned on for the automatic operation of the support 4 with the headstock 5 and 6 and the cutter 7 installed. The support 4 moves by means of a creeper mechanism 9 from the cutter head in the direction of the storage center 8.

At the beginning of the movement, the cutter 7 cuts off the next billet and does not allow it to fall to the base platform. At that moment, when the axis of the clamping locators is at a distance of mm from the rear end position, the slam-shut 7 goes out from under the workpiece and under the pressure of the overlying workpiece falls on the base platform of the storage drive 8.

When --5 mm remains to the end position of the caliper 4, the rear stop of the caliper on :: means to the end switch, through which at the time of the centers coming to the axis of the workpiece, the preform is pre-clamped by the centrifugal detectors. At the time of departure of the center-viewers with the workpiece per mm, the final boost occurs

billet center with tweaks. The operation of pressing the workpiece simultaneously causes it to rotate.

Prp the continuous movement of the caliper 4 rotating with the actuator; comes in contact with the workpiece ;; oh, rotating in the opposite direction. Thus, with continuous movement of the caliper, the workpiece is machined (turned).

At the time of the end of the cutting, the caliper 4 with its abutment presses the second limit switch, as a result of which, when the caliper departs by mm, the center-detectors and centers are expanded and the rotary motion of the workpiece is braked for an instant before falling onto the inclined platform 3.
