Embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, the modified model cutter head of coaxial line stripping machine described in the utility model has a rotating knife headstock 1, integral body is hollow tube-shape, tool rest 11 and cutter lid 12 is installed outside one in one end is provided with, outside described, form four groups of accommodation sections 120 between cutter lid 12 and the interior tool rest 11, this accommodation section 120 is used for holding installs four groups of knife rests 13 and locating rack 14, and limits described knife rest 13 and locating rack 14 radially slides within it;
In conjunction with Fig. 3～shown in Figure 6, be installed with blade 130 on the described knife rest 13, on the described locating rack 14 spacer 140 is installed; The initial position of the blade of described blade 130 and the locating surface of described spacer 140 equates apart from the distance of rotating knife headstock 1 axis; And described blade 130 and described spacer 140 respectively by screw in described knife rest 13 and described locating rack 14.
Again as shown in Figure 1, described rotating knife headstock 1 is provided with four cutting knife tool arm 2a and four location tool arm 2b, the middle part of a described cutting knife tool arm 2a and a location tool arm 2b is articulated in described rotating knife headstock 1 jointly by a fine setting cam pin 20, the end of described cutting knife tool arm 2a and described knife rest 13 interlocks, the other end is equipped with the first roller 2a1; Described location tool arm 2b one end and described locating rack 14 interlocks, the other end is equipped with the second roller 2b1; In conjunction with Fig. 7, shown in Figure 8, described knife rest 13 is setting in opposite directions with described locating rack 14, its intermediate slide 13 is provided with the knife rest groove 131 with the end clamping of described cutting knife tool arm 2a, and locating rack 14 is provided with the locating rack groove 141 with the end clamping of described location tool arm 2b.But adopting the effect of cam pin 20 is initial positions of manual adjustments blade 130 and spacer 140.
In conjunction with shown in Fig. 2,2-1, the 2-2, also has a push broach seat 3 again, described push broach seat 3 and described rotating knife headstock 1 coaxial setting; Described push broach seat 3 is by blade push broach seat 3a and detachable vertically chimeric the forming of spacer push broach seat 3b, and blade push broach seat 3a is positioned at the place ahead of spacer push broach seat 3b; Wherein, described blade push broach seat 3a is provided with the first tilting slide rail 3a1 corresponding with the described first roller 2a1, the described first roller 2a1 places in the described first tilting slide rail 3a1, described spacer push broach seat 3b is provided with the second tilting slide rail 3b1 corresponding with the described second roller 2b1, and the described second roller 2b1 places in the described second tilting slide rail 3b1; The described first tilting slide rail 3a1, the second tilting slide rail 3b1 all are " [" shape, and the described first roller 2a1, the second roller 2b1 place in the corresponding slide rail respectively and form no gap with its each face and contact.
Again as shown in Figure 1, the blade push broach seat 3a of described push broach seat 3 is fixedlyed connected with a push broach bar 4, described push broach bar 4 peripheries are provided with a movable sleeve 41, described spacer push broach seat 3b is fixedlyed connected with described movable sleeve 41, the other end of described movable sleeve 41 connects a spring 42, and the other end of described spring 42 is connected with regulating sleeve 43 on being installed in described push broach bar 4.Described push rod 4 is driven by a cutting knife motor 51 respectively and does axial motion, and is rotated by an electric rotating machine 52 drivings, and cutter motor 51 can pass through screw drive, and electric rotating machine 52 then can pass through belt pulley or gear drive.
After the utility model adopted said structure, its course of work was as follows:
Push rod 4 is done axial motion under the driving of cutter motor 51, because the place ahead blade 130, spacer 140 also do not contact with cable, so push broach seat 3 moves integral body to rotating knife headstock 1 direction, the bottom surface of the first tilting slide rail 3a1 of blade push broach seat 3a makes the first roller 2a1 of cutting knife tool arm 2a one end raise, then under the effect of lever, the other end of cutting knife tool arm 2a will descend, and descend thereby drive described knife rest 13; In like manner, spacer push broach seat 3b drives locating rack 14 by its second tilting slide rail 3b1 and location tool arm 2b;
When the blade of the blade 130 of knife rest 13 contacts with the cable surface that fixes, be that spacer 140 also contacts with the cable surface, cable produces reaction force with blade 130 and spacer 140, because spacer push broach seat 3b promotes by spring on the push broach bar 4 42 and movable sleeve 41, when meeting obstructions, spring 42 is compressed, and spacer push broach seat 3b halts, be that locating rack 14 and spacer 140 also halt, thereby simultaneously 140 pairs of cables of 4 spacers produce pressure and finish the location and look for middle function;
And since between blade push broach seat 3a and the push broach bar 4 for fixedlying connected, be push broach bar 4 when advancing blade push broach seat 3a also keep advancing and break away from chimerism with spacer push broach seat 3b, and then driving blade 140 continues feeds, four blade 140 beginning radial cuts cable epidermises, stop to drive push broach bar 4 after arriving required depth of cut, thereby stop feed; After the blade radial cuts, under the driving of electric rotating machine 52, drive push broach seat 3 and whole rotating knife headstock 1 and upper blade 130 rotation certain commentaries on classics amounts (quantity of rotation) thereof, can cut off the cable epidermis;
Push broach bar 4 inverted running under the driving of cutter motor 51 then, make also counter motion of blade push broach seat 3a, the upper bottom surface of its first tilting slide rail 3a1 makes the first roller 2a1 of cutting knife tool arm 2a descend, therefore the other end of cutting knife tool arm 2a improves, promptly drive described blade 130 and leave the cable surface, after blade 130 leaves cable, blade push broach seat 3a and spacer push broach seat 3b are chimeric again, also counter motion of spacer push broach seat 3b, thereby drive location tool arm 2b locating rack 14 is raise, spacer 140 and blade 130 are return simultaneously.
