Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of coordinated type tool arm of the present utility model, comprise the tool arm body 1 of strip, two have the button cutter pawl 2 of button cutter groove 21 and the top cutter pawl 3 of two thin rod shapes, button cutter pawl 2 is located at tool arm body 1 two ends, be provided with the first containing cavities 11 of tubulose and through-thickness in tool arm body 1 along its length and be provided with the second containing cavities 12 that (mark) suitable for reading be less than end opening (mark), first containing cavities 11 and the second containing cavities 12 intercommunication, top cutter pawl 3 to be arranged in the first containing cavities 11 and to be positioned at button cutter groove 21 side of button cutter pawl 2, top cutter pawl 3 end is hinged with connecting rod 4, connecting rod 4 other end is hinged with ejector pin 5, ejector pin 5 has thinner head 51 and thicker body portion 52, head 51 is suitable for reading through the second containing cavities 12, ejector pin cover plate 6 is provided with outside second containing cavities 12 end opening, ejector pin cover plate 6 is provided with just to the 3rd containing cavities 61 of the second containing cavities 12, ejector pin 5 body portion 51 is accommodated in the cavity that the second containing cavities 12 and the 3rd containing cavities 61 surround, ejector pin spring 5a is clamped with between ejector pin 5 and the 3rd containing cavities 61 bottom surface.Top cutter pawl 3 stretches along tool arm body 1 length direction, and ejector pin 5 stretches along tool arm body 1 width.When not yet capturing cutter 8, ejector pin 5 head 51 is pressed decline, becomes the retraction action of top cutter pawl 3 through connecting rod 4 transmission, now pushes up cutter pawl 3 top and cutter 8 can not be hindered to enter button cutter groove 21; When carrying out grabbing cutter, the button cutter groove 21 of button cutter pawl 2 is near cutter 8, and pin 5 head that now bears down on one removes external force, and ejector pin 5 can by ejector pin spring 5a upwards jack-up, become the extend action of top cutter pawl 3 through connecting rod 4 transmission action, such cutter 8 will be grasped between button cutter pawl 2 and top cutter pawl 3.The benefit of this structure is that the power of grabbing cutter is provided by ejector pin spring 5a, and it is smaller to grab cutter dynamics, more not easy damaged cutter 8; Push up cutter pawl 3 to be controlled by mechanical linkage simultaneously, be quick on the draw, and avoid by clashing into the operating noise produced.
As shown in Figure 3 and Figure 6, be provided with a circular interior heavy face 612 bottom the 3rd containing cavities 62 of ejector pin cover plate 6, one end of ejector pin spring 5a is held on interior heavy face 612.The position of such ejector pin spring 5a is subject to the restriction in interior heavy face 612, and under ejector pin 5 frequent movement, ejector pin spring 5a position can not change, and avoids ejector pin 5 that card occurs.
As shown in Figure 3, Figure 5 and Figure 6, on ejector pin cover plate 6, the exit of the 3rd containing cavities 6 is provided with inward flange 611, is provided with the iner ledge 121 snapped in for inward flange 611 inside the second containing cavities 12.If there is no inward flange 611 and iner ledge 121, ejector pin cover plate 6 is exactly plane with the contact surface of tool arm body 1, this just represents in an installation, second containing cavities 12 wall may not align the 3rd containing cavities 61 wall, both inner edges may protrude from the wall of the cavity of the second containing cavities 12 and the formation of the 3rd containing cavities 61 like this, but from being difficult to identification in appearance, if both walls stagger too large, the inner edge of encountering protrusion is easy in ejector pin 5 advance and retreat process, then there will be card, cause cutter 8 grab incessantly or fail to lay down; The cooperation of inward flange 611 and iner ledge 121 makes to there is a kind of step between tool arm body 1 with ejector pin cover plate 6 and contacts, both fixed position alignment accuracy are just very high, and the inner edge now not having a certain side is projecting inward from cavity significantly, avoiding problems ejector pin 5 and block a problem brought.
As shown in Figure 1, Figure 2, shown in Fig. 6 and Fig. 9, be provided with button cutter ring 22 in button cutter groove 21, the top of top cutter pawl 3 is provided with top cutter projection 31.Actual cutter 8 has a recessed circle 81, such button cutter pawl 2 coordinates when capturing cutter 8 with top cutter pawl 3, button cutter ring 22 and top cutter projection 31 all embed in recessed circle 81, the attitude of such cutter 8 on tool arm is just more stable, problem crooked because of collision when cutter 8 can be avoided to be installed on machine shaft.
As shown in Fig. 2, Fig. 3 and Figure 10, button cutter pawl 2 side is provided with a block 2a, and block 2a protrudes from inside button cutter groove 21.Cutter 8 is in order to be provided with groove 82 with machine spindle is fixing, such cutter 8 just can not skid at work, block 2a on button cutter pawl 2 utilizes the groove 82 on cutter 8 to carry out crawl location, namely block 2a protrudes from the position embedding groove 82 of button cutter groove 21, such cutter 8 would not arbitrarily rotate, more accurate when being installed in machine spindle.
As shown in Fig. 2, Fig. 3 and Fig. 7, the side in cutter pawl 3 stage casing, top is provided with stopper slot 32, tool arm body 1 is fixed with limited block 7, limited block 7 comprises integrated stator 71 and tappet 72, stator 71 is provided with and penetrates in stopper slot 32 for tappet 72 for a pair fixing hole 711, first containing cavities 11 side direction perforate fixing with tool arm body 1.Top cutter pawl 3 is when stretching, mainly limit maximum advance and retreat distance by the tappet 72 on limited block 7, even if the shock that tappet 72 is subject to pushing up cutter pawl 3 is also not easy to affect its fixing with tool arm body 1, if tappet 72 serious wear, then change whole limited block 7, compare spacer pin 7 ' limit method, be not easy fracture, longer service life, also can not bring whole tool arm body 1 to need the trouble of replacing because of deformed threads.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
