Table saws, on the contrary, in the process, can be easily exhibited at the height of the saw blade with the integrated lifting mechanism. On the right side of the table “buzz-saws” on the longitudinal guide mechanism is placed with the scale adjusting the angle, by which it is possible to produce stippling of the ends of boards, not only direct, but also at any angle in between. The basis of this mechanism taken as a suitable tool for hand saws.
Notice that the described fixture can be easily removed: removed or lowered. The longitudinal guide rail is made of steel pipe with a diameter of 17 mm, its fixing is done using brackets, Ushkov on the edges of the table circular saw.
On the same side of the table by means of the clamping bar bolts M10 to the table is mounted a guide strip made of rolled steel angle 50×50 mm. distance between the saw blade and strap is determined by the width of the cut workpiece. And she strap helps to maintain a predetermined width along the entire length of the workpiece without marking the latter.
The lifting mechanism of the table “buzz-saws” and the mount table of the guide:
1 —frame, 2—resistant cross member frame (50×50 area); 3 —Jack (screw М20х2); 4—resistant cross member of the lift table (area 45×45); 5—stopper lifting table (special screw M12x1,5,2); 6—circular saw; 7—guide bar; 8—drawer side (area 40×40, 4x); 9—stand lifting table (area 40×40, 2); 10—strut (40×40 area, 2); 11—countertop; 12—additional front frame; 13—clamping bar (steel, 2); 14—poluchili-lock nut M10 (2 sets.); 15—special screw M10 2 PCs.)
A mechanism for the parallel machining of workpieces (parts of POS. 3,4,6 used from attachments for hand saws):
1—Foundation (Board s15); 2—focus (Board s18); 3—front (steel); 4—the plate scale (steel); 5—fastening of the plate to the base (bolt M8 2); 6—the stopper (special nut M8 knurled); 7—fastening of the bushing to the base (nut M8 2 PCs); 8—lifting table “buzz-saws”; 9—bracket mounting rail to the table (sheet s5, 2 PCs.); 10—guide rod (pipe Ø17); 11 —backing plate (steel, sheet s5); 12—bushing (steel, 2); 13—fastening of the guide rod (screw M12 2 PCs.)
The drive of a rotor — work (instrumental) shaft — carried double-strand V-belt transmission (although in practice I use only one strap) from the three-phase (380 V) motor power 3 kW with a speed of 1500 rpm. The engine is located at the bottom inside the frame and pivotally mounted to the suspended cantilever subframe, which allowed to solve the problem of belt tension without additional video. To ensure the quality of processing the material, the rotational speed of the working shaft has been increased due to the accelerating belt transmission. The drive pulley diameter of the motor is larger than the diameter of the pulley working shaft in half, therefore, the knife rotor and a circular saw rotating with an angular speed of about 2250 rpm. The motor power supply is via four-core cable, wiring done with all the requirements of safety standards, the frame is grounded. In case of short circuit or overcurrent starting machine is capable of almost instantly the power is switched off in automatic mode. After work, the machine should be shut down, cleaned of chips and dust.
The machine has been operating for six years. Spend routine maintenance: syringes bearing, check condition of mounting the knives of the jointer, the condition of the teeth of the saw blade, inspect V-belts for the drive and power cables of the machine.
Not superfluous to recall that the machine refers to the mechanisms of increased danger. The rotating parts are not used and cutting tools, you must close the fixed covers. The work on the machine requires the utmost concentration, compliance with safety regulations. Do not rush, do not force to speed up the process, work hard at your pleasure. The workplace of the joiner should be well lit, the space around the machine is free enough, the flooring is not slippery.
