Through the design of the special clamp, the striking covers are uniformly distributed on the clamp, and the circle center of the large outer circle is concentric with the rotating center of the clamp, so the milling processing is ingeniously changed into the lathe cutting processing, the difficult problem of outer circle processing of the striking cover is solved, the efficiency is improved, and the striking cover turning clamp is suitable for mass production.
Description
Technical field
The present invention relates to the pneumatic tool processing technique field, relate in particular to and hit cover manufacture field, particularly a kind of strike cover turning clamp.
Background technology
Hit cover and be in the pneumatic tool extremely widely driving element of a kind of use, it can be with the air tool output of being delivered to of power source cycle.Strike covers on the processing that often needs multiple working procedure in the production process and just can finish, be the little cylindrical of rough-cast-heat-treatment of annealing-rough turn end face-bore hole-car-finish turning end face-large cylindrical of boring-car-mill square hole-broaching square hole-broaching internal tooth-final heat treatment, for the processing of hitting the large cylindrical of cover, be illustrated in figure 1 as and hit the cover schematic diagram, two wider circular arcs are large cylindrical, usually can only take the method for milling, namely use the large cylindrical of numerical control machining center Milling Process, but this method clearly equipment cost is higher, and batch production efficient is low.
Summary of the invention
The technical problem to be solved in the present invention is: in order to enhance productivity, reduce production costs, solve and hit the unmanageable manufacturing bottleneck problem of the large cylindrical of cover, to adopt the numerical control machining center milling to change the employing lathe turning processing into, in order to reach this purpose, a kind of strike cover turning clamp is provided, utilizes this clamp clamps to hit cover and be implemented in turning on the lathe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of strike cover turning clamp, be used for clamping and hit cover, comprise positioning seat, described positioning seat comprises round plate and locating dowel, round plate wherein end face central authorities arranges locating dowel, the edge of other end circumferentially is evenly equipped with at least two locating shafts, a pin-and-hole is respectively opened in the both sides of each locating shaft, the pin-and-hole of each locating shaft both sides is symmetrically set, be equipped with in the pin-and-hole and will hit the fixing bearing pin of cover, the pivot of described positioning seat with hit cover be fixed to hit the large cylindrical of cover behind the locating shaft the center of circle for concentric, comprise that also one is fixedly set in each locating shaft head and will hits the pressing plate that covers compression.
Further, for for convenience detach, described locating shaft head has screw thread, and described pressing plate is fixedly connected with by nut with each locating shaft head.
The locating dowel of positioning seat partly is fixed on the lathe chuck, positioning seat just can rotate like this, to hit cover is fixed in the pin-and-hole by bearing pin, uniform hitting cover on the round plate of positioning seat, the large cylindrical of so a plurality of strike covers just can form a circle, and the center of circle of this circle is the pivot of positioning seat, therefore as long as guarantee that the pivot of positioning seat is concentric with the center of circle of hitting the large cylindrical of cover, utilize such anchor clamps, just can utilize smoothly lathe to process, no longer need Cutter Body Processing with Machining Center, improved working (machining) efficiency, saved processing cost.
The invention has the beneficial effects as follows, the present invention is by design one special fixture, be distributed on the anchor clamps hitting cover, make the center of circle of its large cylindrical concentric with the pivot of anchor clamps, so just dexterously Milling Process has been made into lathe grinding processing, solved a difficult problem of hitting the cover processing excircles, improved efficient, be fit to produce in enormous quantities.
Description of drawings

Fig. 3 is the left view of Fig. 2;
Fig. 4 is the right view of Fig. 2;
Fig. 5 is strike cover parts fixation schematic diagram of the present invention.
Among the figure: 1. positioning seat, 11. round plates, 12. locating dowels, 2. locating shaft, 3. pin-and-hole, 4. bearing pin, 5. pressing plate, 6. nut.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Such as Fig. 2 Fig. 3 Fig. 4, this hits the cover turning clamp and is used for clamping strike cover, comprise positioning seat 1, positioning seat 1 comprises round plate 11 and locating dowel 12, round plate 11 wherein end face central authorities arranges locating dowel 12, the edge of other end circumferentially is evenly equipped with four locating shafts 2, a pin-and-hole 3 is respectively opened in the both sides of each locating shaft 2, the pin-and-hole 3 of each locating shaft 2 both sides is symmetrically set, be equipped with in the pin-and-hole 3 and will hit the fixing bearing pin 4 of cover, the pivot of positioning seat 1 is fixed to locating shaft 2 rear strikes with the strike cover and covers the center of circle of large cylindrical for concentric, comprise that also one is fixedly set in the pressing plate 5 that each locating shaft 2 head will hit the cover compression, locating shaft 2 heads have screw thread, and pressing plate 5 is fixedly connected with by nut 6 with each locating shaft 2 head.When cover is hit in production and processing, such as Fig. 1, according to the radius size of hitting the large cylindrical of cover, determine that can be circumferentially uniform what be individual, select again corresponding anchor clamps, it is the selection of positioning seat 1, such as Fig. 5, take large exradius size R60.77 as example, be chosen in and circumferentially arrange four on the round plate 11 of positioning seat 1 and hit cover, these four centers of circle of hitting the circle of the large cylindrical formation of cover are concentric with the pivot of positioning seat 1, hitting cover with four is set with on locating shaft 2, bearing pin 4 is aimed in the hole of hitting on the cover, because the Position Design of pin-and-hole 3 is horizontal when cover is positioned at the clock 0:00 direction for making to hit, so just guaranteed that four large cylindricals that hit cover can be on same circular arc, and then cover pressing plate 5, with nut 6 lockings, 12 chucks by lathe of the locating dowel of positioning seat 1 are clamped, pressing plate 5 is by top the holding out against in the tail stock, behind the starting lathe, each hits a wherein large periphery of cover turning, and after turning was complete, manual each is hit covered 180 ° of upsets, after fixing, again start lathe, another large periphery of turning is by such sleeve clamp, just realized hitting to cover in the lathe processing, and no longer need the milling of the work in-process heart, and improved efficient, be fit to produce in enormous quantities.
Different according to the size of hitting the large cylindrical of cover, the strike cover quantity that can arrange on positioning seat 1 so is also just different, strike covers on the positioning seat 1 circumferentially, and uniform quantity also can be 2, positioning seat 1 can be little than above-mentioned 4 embodiment that hit in the cover in this case, can also according to circumstances be chosen in equally on the positioning seat 1 and to arrange that 6 are hit cover or more, therefore only need to satisfy hit cover uniform after each center of circle of hitting the circle that the large cylindrical of cover consists of overlap with positioning seat 1 pivot and get final product.
