The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is made further description explanation.
A kind of Pneuamtic cradle as shown in Figure 1 comprises the stepless pressure regulating mechanism of reel cage positioning and fixing retaining mechanism and spiral, and the reel cage fixing and locking is regulated with pressure and separated independent design, does not disturb mutually.Reel cage positioning and fixing retaining mechanism comprises that supporting goes up card 4, the fastening card 5 down of supporting, hexagonal support column 10, fixedly square nut 71 and holding screw 72; The stepless pressure regulating mechanism of spiral comprises pressure transmission crank 3, adjusting screw(rod) 8, lock screw 9 and air bag 12; Contact the fulcrum place with pressure transmission crank 3 and be provided with a pressure guide 11; Through changing the height that pressure transmission crank 3 contacts with pressure guide 11, realize the adjusting of pressure.
It is point articulated to block 4 employings one in the supporting, and hinge type connects fixing, makes reel cage that basic precision height, reel cage height are installed; Front leather roller position consistency property precision is high, the depth of parallelism, and simultaneously, installation saves time fast; Reduce labour intensity, shake out the fastening card down of supporting 5 along the hinge fulcrum, block 4 in the supporting and fix pressure guide 11, be stuck on the hexagonal support column 10; Another point adopts the fastening half slide structure of screw, and through the fixedly tension of square nut 71 and holding screw 72, thereby the secure fixation of realization reel cage is not rotated; The fixing and locking mode is simply firm, and simple to operate quick, labour intensity is low, high efficiency.
Pressure transmission crank as shown in Figure 23 upper ends are provided with a pivot point 31, and the lower end is provided with one second internal thread cylindrical hole 32, and terminal bottom is provided with one second internal thread cylindrical hole 33.
Adjusting screw(rod) 8 as shown in Figure 3 is made up of the external screw thread cylinder 82 that the internal thread of a spheroid screw head 81 and the one and first internal thread cylindrical hole matches.Screw head 81 contacts with an air bag 12, can realize the variation of adjusting screw(rod) 8 upper and lower displacements with regulating spanner rotation external screw thread cylinder 82, thereby adjust the distance of screw head 81 and pressure transmission crank 3; Adjust the level of compression of 81 pairs of air bags 12 of screw head simultaneously, utilize the elasticity of air bag 12 to realize that pressure transmission point is the height change of screw head 81, it is highly changed thereby pressure transmission crank 3 is rotated around pivot point; Thereby change the height of pressure transmission crank 3 and pressure guide 11 contact points, realize the adjusting of pressure, again through 3 pairs of handles 2 of pressure transmission crank; Support the fastening effect of card 5 down pressure is changed, thereby, adopt the crank stepless pressure-regulating device to regulate the operating pressure of reel cage; Reel cage pressure is regulated fast; Accurately, the stepless voltage regulation space is big, easy to operate saving time.
Thereby lock screw 8 is through reaching the purpose that pressure quick and precisely locks with realizing the locking to adjusting screw(rod) 8 being connected of the second internal thread cylindrical hole 33, and its pressure self-locking property is strong, and pressure drift amount is little; Kept immobilizing of pressure transmission point simultaneously, thereby the pressure transmission of pressure transmission crank 3 is highly immobilized, realized that reel cage pressure is steady in a long-term; Maintenance period is long, and it is time saving and energy saving that pressure is regulated maintenance, and difference is little between the pressure ingot; The depth of parallelism is good; Spinning quality is high, has reduced labour intensity, has improved economic benefit.
Above-described only is optimal way of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these also should be regarded as within protection scope of the present invention.
