SU918095A1 - Device for milling the edges of wooden parts - Google Patents

Description

The device for milling torsional parts can be used in the woodworking industry, in particular, for milling the joined edges when gluing the panel details of furniture.

A device is known for milling the edges of wooden parts, including a stand with tables between which a milling head with an actuator mounted on the guides, mounted above each table, a pressure device, and a mechanism for parts basing. However, this device has low productivity and accuracy of parts, especially large edge length.

The purpose of the invention is to improve the performance and accuracy of machining parts.

The goal is achieved by the fact that the device is equipped with two traverses and an additional mechanism for positioning the parts, the main and additional mechanisms for positioning the parts being mounted on traverses and having at least two interlocking pivot stops, and the pivot axes of the latter are perpendicular to The shuffles are re-machined milling head axes.

The clamping device can be made in the form of spring-loaded levers, which are located along the traverse.

Figure 1 shows the proposed device; figure 2 - the same view

10 above; on fig.Z - section aa in figure 1; figure 4 - mounting stops; figure 5 - section bb in figure 1.

The device consists of a frame 1, on which the fixed

t5 table 2 and table 3, adjustable in height by means of screws 4 and guides 5.

Guides b are also mounted on the bed 1, along which the milling head 7 moves in a protective casing 8.

Above the tables 2 and 3, in the upper part of the bed, traverses 9 are installed with clamping devices in the form of non-movable pneumatic chambers 10 and swinging spring-loaded levers 11 with a corrugated surface. The traversing mechanisms also have basing mechanisms in the form of lugs 12, fixed 30 kn and can be rotated on axles

13 by means of a common rod 14 through the hinge 15 from the pneumatic cylinders 16. The parts 17 to be machined are placed individually on tables 2 and 3 to the stops 12. The milling head 7 is moved along the guides 6 by means of an actuator 18.

The device works as follows.

Parts 17, which are subject to processing, are laid alternately on tables 2 and 3 up to stops 12, which are in the initial position and are evenly spaced along the entire length of tables 2 and

3

After loading parts 17, compressed air from the pneumatic system is fed into the cavity of pneumatic cylinders 16, which are kinematically connected with rods 14,

When the rods 14 move by means of pneumatic cylinders 16, the stops 12 are removed from the treatment zone. At the same time, compressed air enters pneumatic chambers 10, which, by pumping out spring-loaded levers 11 with a corrugated surface, fix part 1 in a stationary state 4

After that, the feed drive 18 of the milling head 7 is turned on and the edges of the parts 17 are simultaneously processed. When the work cycle is performed, the milling head leaves the edge treatment zone, compressed air is removed from the pneumatic chambers 10 o. Due to the elastic forces of the compression springs of the levers 11.

At the same time, the compressed air enters the other cavity of the pneumatic cylinders 16, and the stops 12 occupy the initial position. Parts with machined 1-1 1.

the edges are manually unloaded from tables 2 and 3. The cycle is repeated.

When processing a complex profile. the edges (for example, simultaneous processing in one edge of the tongue and the other ridge) table 3 is shifted in height relative to table 2 by means of screws 4.
