Definitions

• a ring-shaped main body fitted to a slit shaft is provided with a main body fixing mechanism for fixing the main body to the rotation shaft.
• the main body fixing mechanism is a mechanism for reducing the inner diameter of the main body.
• a cylindrical pressure chamber is provided concentrically along the inner peripheral surface of the main body, and a pressure chamber having a leading end communicating with the pressure chamber is provided.
• a pressurizing piston is fitted in the pressurizing chamber.
• the pressure chamber and pressurization chamber are filled with oil.
• a screw hole communicating with the base end of the pressurizing chamber is provided on the outer peripheral surface of the main body, a screw shaft is screwed into the screw hole, and the tip of the screw shaft contacts the pressurizing piston of the pressurizing chamber.
• the main body is provided with a small diameter portion having a small outer diameter and a large diameter portion having a large outer diameter.
• the ring-shaped blade is fitted on the small diameter portion of the main body and overlaps the end face of the large diameter portion of the main body.
• the pressing device of the first conventional example is fitted and attached to the small diameter portion of the main body.
• the pressing device is screwed with a screw shaft exposed on the outer peripheral surface, presses the blade with uniform pressing force with a plurality of pressing pistons protruding from the front surface, and fixes the blade to the end surface of the large diameter part of the main body. I have.
• the space holding member and the nut between the blade pressing and fixing device and the nut are not required, and the trouble of attaching and detaching the space holding member and the nut is saved.
• I will When changing the position of the blade on the rotating shaft and the clearance between the upper and lower blades, the time required to replace the spacing material and the clearance adjusting material is reduced. Production efficiency does not decrease significantly even in the production of many types and small quantities.
• the main body is provided with a main body fixing mechanism that fixes the main body to the slit shaft, and a blade pressing mechanism that presses the spacing material fitted with the slit shaft and the blade with an equal force.
• a blade pressure fixing device characterized by not providing a configuration for mounting an evening blade.
• the above-mentioned main body fixing mechanism is a mechanism in which, for example, when a fixing screw shaft is screwed in, the inner diameter of the main body is reduced and the main body is fixed to the rotating shaft of the slipper.
• the space holding material and the nut between the blade pressing and fixing device and the nut are not necessary for the upper and lower rotating shafts, and the space holding material and the nut are attached and detached. Time is saved. When changing the position of the blade on the rotating shaft and the gap between the upper and lower blades, the time required to replace the spacers is reduced. Production efficiency does not decrease significantly even in the production of many types and small quantities.
• FIG. 9 is a front view of the left side portion of the blade pressing and fixing device.
• the extruding mechanisms 22 to 30 are, like the pressing mechanisms 3 to 10 of the main body fixing mechanisms 2 to 13, holes having a circular cross section opened on the outer peripheral surface of the main body 1.
• the bottom portion of the hole is formed in the pressurizing chamber 23, the open side portion of the hole is formed in the screw hole 24, and the bottom of the pressurizing chamber 23 is connected to the oil passage 22 through the passage 25.
• a pressurizing piston 26 is fitted in the pressurizing chamber 23, and oil is filled in the rear chamber of each piston hole 16, oil passages 22 and passages 25, and the bottom part of the pressurizing chamber 23. are doing.
• two rotating shafts 42 are bridged between left and right side plates 41 and bearings, and both rotating shafts 42 are vertically arranged in parallel.
• the upper rotating shaft 42 can move up and down together with the left and right bearings 44 to which the bearings 43 are fitted.
• the side plate 41 can move left and right together with the upper and lower bearings 44 attached to the side plate 41.
• the upper and lower rotating shafts 42 have their left ends connected to a motor (not shown), and can be driven to rotate in opposite directions.
• Each of the two rotating shafts 42 has a large-diameter retaining portion 45 inside the left-end bearing portion 43 and a small-diameter thread portion 46 inside the right-end bearing portion 43.
• a portion between 5 and the screw portion 46 is a blade fixing portion 47 having a smaller diameter than the retaining portion 45 and a larger diameter than the screw portion 46.
• the upper and lower double blade pressing and fixing devices 1 to 13 and 16 to 30 respectively screw the fixing screw shaft 7 exposed on the outer peripheral surface of the main body 1 with a rotating tool to reduce the inner diameter of the main body 1,
• the main body 1 is concentrically fixed to the blade fixing portion 47 of the rotary shaft 42.
• the double-blade tool pressing and fixing devices 1 to 13 and 16 to 30 respectively screw the pressing screw shaft 27 exposed on the outer peripheral surface of the main body 1 with a rotary tool, and advance each pressing piston 17. Then, each pressing piston 17 presses the adjacent spacing member 48 with an even large force.
• a fixing mechanism for fixing the cylindrical body 61 is provided.
• a plurality of screw holes 62 are radially penetrated at equal intervals at the right end of the cylindrical body 61, and a screw 63 with a hexagonal hole is screwed into each screw hole 62.
• Each screw 63 is screwed in, and a soft plate fixed to the tip of each screw 63 is pressed against the screw tooth portion 46 to fix the cylindrical body 61.
• a rotation mechanism for rotating the cylindrical body 61 is provided.
• a plurality of concave portions 64 are provided on the right end face of the cylindrical body 61 at equal intervals. A rotating tool such as a wrench is hooked on the concave portion 64 to rotate the cylindrical body 61.
