Description

(5) MACHINE FOR PROCESSING SHEETS BY PERIMETER

I

The invention relates to timber industry, in particular to the production of parquet boards.

Known machines for processing shields around the perimeter include a bed with guides, a carriage with a bracket, a rotary table with a vertical shaft, the upper end of which is fixed in the center of the table, and the lower one with a pneumatic cylinder of the table rotation mechanism, a clamping element, a clamp and cutting tools l and 2.

However, the pneumatic cylinder of the rotation mechanism of the known devices does not have a damper, and in the extreme position a sharp blow of the table finger against the support / carriage is obtained. And since the working surfaces of the table and the clamp are smooth, the product slips out of the impact and during the subsequent processing of the other two edges, their perpendicularity is disturbed, i.e. the required shield quality is not ensured. In addition, from sharp blows together with the product is turned more than 90 ° and the clamp. And since the clamp is metal, then during subsequent processing, its edges can get on the saws or mills, which does not provide safety work.

The purpose of the invention is to improve the quality of the processing of the shields and ensure the safety of work.

The goal is achieved by the fact that the clamp is provided with a retainer on the form of a spring-loaded ball and a bar with holes, and the pneumatic cylinder of the table turning mechanism is equipped with a damping damper, the working surface of the table is made corrugated, and the clamp with a rubber pad.

FIG. 1 shows a machine for processing shields around the perimeter, a general view; in fig. 2 is its carriage, cut in FIG. 3 - locking type A in figure 2; in fig. i is a section B-B in FIG. 2 on the damper; in fig. 5 is a view of B in FIG. (on top of the plug). The machine includes the base 1 on which the saw milling heads 2 are fixed. A carriage 3 is installed on the guide bars. A rotary table is installed on the upper surface of the carriage, the working surface 5 of which is made corrugated. The turning mechanism 6 is fixed on the bottom surface of the carriage; the pneumatic cylinder 7 of which is equipped with a shock-absorbing damper 8. The end face of the rack has a clamp 9 of the product 10 installed through the bracket, the working surface of the clamp is provided with a rubber lining 11. The clamp is equipped with a clamp 12 installed in the height-adjustable bracket 13. clamp It consists of a ball, And, a spring 15 and a bar 16, two vertices at the end points. The machine works as follows. The product 10 is laid on the grooved surface 5 of the turntable f. Includes all sawing and milling heads 2. At the same time, clamp 9 is activated and, with its rubber pad.11, presses the product 10 against the turntable k. Spring-loaded ball 14 latch 12 locks the clamp in the initial position. As the carriage 3 moves, two opposite edges and divide 10 are machined. Pass through the new group of saw and milling heads, the carriage 3 stops. The turning mechanism 6 is turned on. The turning table, the product 10 and the clamp 9 are rotated by 90. At the final turning point, the damper 8 is actuated by the pneumatic cylinder 7, which absorbs the impact. In conjunction with the clamp, the plan b is rotated. 4 ka 16, which has two holes at the end points at an angle of 90 °. In the latter, the ball lA of the retainer 12 feeds in from the strap 16. Thus, the introduction of the corrugated surface of the table, the rubber pad of the clamp, the retainer and the damper makes it possible to rotate the table and perpendicular to the edges of the shield when turning the table, and also to improve the quality of the product and improve technical safety when working. Invention Formula Machine for processing shields along the edge, including a bed with guides, a carriage with a bracket, a rotary table with a vertical shaft, the upper end of which is fixed in the center of the table, and the lower section is engaged with a pneumatic cylinder of the table turning mechanism, clamping element, clamp and cutting working bodies, characterized in that, in order to improve the quality of processing of the shields and ensure safety of operation, the clamp is provided with a lock in the form of a spring-loaded ball and a plate with holes, and the pneumatic cylinder of the rotation mechanism la - amortiziruschim damper, wherein the table surface is made of corrugated and pressing - with rubber lining.
