Description
Technical field
The utility model relates to tooth bar clamp for machining field, is specifically related to a kind of for milling machine tooth bar clamp for machining.
Background technology
Tooth bar refers to: a kind of tooth is distributed in the special gear on bar shape.Tooth bar also divides spur rack and diagonal-cut rack, matches respectively use with straight spur gear and helical gears; The flank profil of tooth bar is straight line non-involute (be then plane for the flank of tooth), is equivalent to the gear that reference radius is infinitely great cylinder.
Usual tooth bar processing method: gear hobbing, gear shaping, shaving, roll flute and gear honing is wherein modal two kinds of tooth bar processing methods with gear hobbing and gear shaping.
The blank of tooth bar, before processing tooth, needs to carry out roughing to blank, after treating preliminary working, carries out milling flat to the upper and lower surface of workpiece, and in the slabbing smooth guarantee following process process on upper and lower surface, the tooth processing on tooth bar is qualified.If the upper and lower plane machining of workpiece is defective, in the process of gear hobbing or gear shaping, easily " forging a knife ".To forge a knife finger: in process, the damaged or whole cutter of the blade part of cutter ruptures.The processing on the upper and lower surface of workpiece is extremely important as can be seen here.
Usual manufacturing gear strip upper and lower surface time, adopt pressing plate be fixed, that is: by bolt, pressing plate is fixed, rely on pressing plate workpiece is positioned., there is the shortcoming that fixed efficiency is low in this fixed form, often processing a workpiece all needs dismounting, installs pressing plate once, affects working (machining) efficiency.
The term " upper and lower surface " used in this background technology refers to: after tooth bar blank completion of processing, and when workpiece level is placed, the face of tooth to be processed is upper surface, the face just right with the flank of tooth to be processed is lower surface.
Utility model content
The purpose of this utility model be to provide a kind of Quick holding part for milling machine tooth bar clamp for machining.
For achieving the above object, the technical solution of the utility model is as follows:
The base case that this programme provides is: for milling machine tooth bar clamp for machining, and comprise holder and the electromagnet base being positioned at same level, holder top is provided with the groove holding workpiece, and holder is provided with support bar; Also comprise can with the Z-shaped bar of electromagnet base intermittent contact, this Z-shaped bar comprises the upper ejector pin, the dwang that connect successively and has ferromagnetic lower push rod; Described support bar and dwang are rotationally connected.
The operation principle of base case and beneficial effect are: during electromagnet base energising, electromagnet base provides magnetic force that lower push rod is moved to electromagnet base direction to lower push rod, now lower push rod drives dwang to rotate, dwang drives upper ejector pin motion, when lower push rod contacts with electromagnet base, upper ejector pin and absorption surface, and Work-sheet pressing is fixed.After work pieces process, electromagnet base power-off, Z-shaped bar relies on the weight of self that Z-shaped bar is swung around the pin joint of support bar and dwang, and now upper ejector pin moves to the direction away from workpiece, and workpiece is in non-blessing state, is taken away by the workpiece processed.
This fixture only need be energized to electromagnet base when clamping work pieces, only need to electromagnet base power-off when unclamping workpiece.Compare tradition by pressing plate fixation workpiece, this fixture has Quick-clamped, changes the feature of workpiece.
Preferred version one: based on the preferred version of scheme, the end of described upper ejector pin is provided with bolster.During upper ejector pin contact workpiece, eliminated the noise by bolster, avoid ear-piercing impact noise to produce.
Preferred version two: based on the preferred version of scheme or preferred version one: be provided with return unit between described holder and dwang, this return unit can make Z-shaped bar Rapid reset.
Preferred version three: the preferably preferred version of two: the arm of force of described upper ejector pin and the arm of force of lower push rod are than being 1:2 ~ 4.Can realize labour-saving effect, make less magnetic force realize upper ejector pin to workpiece larger clamping force, arm of force ratio is applicable to actual production more in 1:2 ~ 4.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for milling machine tooth bar clamp for machining embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: holder 1, electromagnet base 2, groove 3, support bar 4, upper ejector pin 5, dwang 6, lower push rod 7, rubber blanket 8, extension spring 9, workpiece 10.
Embodiment is substantially as shown in Figure 1: for milling machine tooth bar clamp for machining, and comprise holder 1 and be positioned at the electromagnet base 2 of same level, holder 1 top is provided with the groove 3 holding workpiece 10, holder 1 is welded with a support bar 4.This tooth bar clamp for machining also comprise can with the Z-shaped bar of electromagnet base intermittent contact, this Z-shaped bar comprises the upper ejector pin 5, dwang 6 and the lower push rod 7 that connect successively, wherein upper ejector pin 5 is one-body molded with dwang 6, and lower push rod 7 is ferromagnetism bar, and namely lower push rod 7 is iron bar.Support bar 4 and dwang 6 pivot joint.
The end of upper ejector pin 5 is provided with bolster, and this bolster is rubber blanket 8; Be provided with return unit between holder 1 and dwang 6, this return unit is extension spring 9.The arm of force of upper ejector pin 5 and the arm of force of lower push rod 7 are than being 1:2, and the clamping force of upper ejector pin 7 workpiece pressing 10 is twices of the magnetic force of electromagnet base 2 pairs of lower push rods 7.
During concrete enforcement, when electromagnet base 2 is energized, electromagnet base 2 provides magnetic force that lower push rod 7 is moved to electromagnet base 2 direction to lower push rod 7, now lower push rod 7 drives dwang 6 to rotate, extension spring 9 is stretched, dwang 6 drives upper ejector pin 5 to move, and finally makes upper ejector pin 5 contact with workpiece 10, and is fixed by workpiece 10.When after workpiece 10 completion of processing, electromagnet base 2 power-off, Z-shaped bar relies on the weight of self and the elastic force of extension spring 9 to swing around the pivoting point of support bar 4 with dwang 6, reach the object of Rapid reset, now upper ejector pin 5 moves to the direction away from workpiece 10, workpiece 10 is in non-blessing state, is taken away by the workpiece 10 processed.
The term " ferromagnetism bar " used in this description refers to: have ferromagnetic rod member.Ferromagnetism (Ferromagnetism) refers to a kind of magnetic state of material, has idiopathic magnetization phenomenon, is widely known by the people most in each material with iron, therefore named it.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
