Abstract
The utility model discloses a mould jig of a gear milling machine. The mould jig comprises a fixing seat (1), a locking nut (2) screwed at one end of the fixing seat (1) and a pressing sleeve (4). A seal cover is arranged at one end of the locking nut (2); a through hole is formed on the seal cover; a spindle (7) extending out of the upper end surface of the fixing seat (1) is arranged in the center of the fixing seat (1); a plurality of positioning pins (5) are arranged on the upper end surface of the fixing seat (1); a back cover is arranged at the upper end of the pressing sleeve (4); a through hole with the diameter larger than that of the spindle (7) is formed on the back cover; the pressing sleeve (4) is positioned in the through hole; the lower part of the pressing sleeve is extruded at the inner sides of the positioning pins for realizing the radial positioning; a lug boss is also arranged on the outer circular surface of the pressing sleeve (4); and a nut lever (6) is fixed on the locking nut (2). The mould jig has the advantages of high efficiency and good quality of processed helical gears, thereby greatly improving the economic benefit of factories.
Description
Technical field
The utility model relates to a kind of anchor clamps, exactly is the milling machine tire anchor clamps that a kind of milling machine is used for fixing gear when adding work gear.
Background technology
Helical gear is made the field, though helical gear part processing part is little, processing technology complexity and specification requirement are all than higher.In order to guarantee helical gear processing technology and machined required precision, accomplish the production efficiency efficient quick.Must possess the special-purpose tire clamp fixture of a kind of lathe for each road production process, that is to say that the per pass production process finishes on special-purpose tire clamp fixture.The dark 4.2mm groove of wide 7mm manufacturing procedure with helical gear is an example, this operation generally on universal milling machine Milling Process form, there are not special-purpose tire anchor clamps, each single-piece work clamping is time-consuming, operating efficiency is low, helical gear machined precision is difficult to control, and product quality can not get guaranteeing, the low serious puzzlement economic benefit of enterprises of product percent of pass.The production efficiency of helical gear and product precision improve and quality control, have become development matter of utmost importance anxious to be solved.
The utility model content
The purpose of this utility model solves existing gear exactly when milling system because of no special fixture, cause of low quality, the problem that efficient is not high.
The technical solution adopted in the utility model is: gear milling machine tire anchor clamps, it is characterized in that it comprises holder, the locking nut and the gland that connect with the holder threaded one end, locking nut one end is capping, capping is provided with through hole, the center of holder is provided with the mandrel that stretches out the holder upper surface, the upper surface of holder is provided with several alignment pins, the gland upper end is provided with back cover, back cover be provided with greater than the through hole of axle diameter, the through hole bottom that is positioned at of gland is squeezed in the inboard realization of alignment pin radial location, also be provided with boss on the periphery of gland, be fixed with the nut lever on the locking nut.
Adopt technique scheme, when adding work gear, geared sleeve is equipped with on the holder mandrel, load onto gland, the gland bottom surface is squeezed on the alignment pin, installs locking nut again, and the rotating nut lever, locking nut is rotated, locking nut drives and compresses gland in the process that moves down, make gland extruding gear, thereby make the gear axial location, like this gear shaft to radially can both locate.
In sum, the utility model beneficial effect is: owing to use this in fact to use novel, to be processed gear can both locate radial and axial, therefore can on milling machine, realize accurately processing, thereby improved machining accuracy, the Gear Processing quality is improved, the also big raising of efficient.

Fig. 1 is the utility model schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1, holder, 2, locking nut, 3, helical gear, 4, gland, 5, alignment pin, 6, the nut lever, 7, mandrel, 8, boss.
The specific embodiment
The utility model gear milling machine tire anchor clamps, as Fig. 1, shown in Figure 2, it comprises holder 1, the locking nut 2 and the gland 4 that connect with holder 1 threaded one end, locking nut 2 one ends are capping, capping is provided with through hole, the center of holder 1 is provided with the mandrel 7 that stretches out holder 1 upper surface, the upper surface of holder 1 is provided with several alignment pins 5, gland 4 upper ends are provided with back cover, back cover is provided with the through hole greater than axle diameter, the through hole bottom that is positioned at of gland 4 is squeezed in alignment pin 5 inboard realization radial locations, also is provided with boss 8 on the periphery of gland 4, is fixed with nut lever 6 on the locking nut 2.
When helical gear 3 is sleeved on the mandrel 7, install gland 4 more like this, install locking nut 2 and rotating nut lever 6 again, can fix helical gear 3, helical gear 3 all is fixed radial and axial.
