Abstract
The invention discloses a shifting fork drilling clamp which aims at achieving the purposes of precise location in the shifting fork drilling process and improving machining quality. The shifting fork drilling clamp comprises a clamp body. The clamp body is provided with a locating spindle penetrating a fork head hole and further provided with a flat pin used for being located between shifting fork feet. The two sides of the flat pin are provided with arc-shaped faces matched with the inner rims of the shifting fork feet, and the clamp body is further provided with a clamping block used for pressing a fork head upwards. The clamping block is located under the flat pin. A drill plate abutting against the lower portion of the fork head is hinged to the clamp body and is in threaded linkage with a locking screw. The tail end of the locking screw penetrates the drill plate and is in threaded linkage with the clamp body. A drill bit locating hole in the drill plate is located between the flat pin and the clamping block. The geometrical centers of the flat pin, the drill bit locating hole, the locating spindle and the clamping block are collinear from top to bottom. A drill bit of a drilling machine can conduct drilling on the fork head in the radial direction through the drill bit locating hole, cutting force is small in the drilling process, and the stable drilling work can be achieved.
Description
Technical field
The present invention relates to a kind of shift fork boring grab.
Background technology
Shift fork is the parts on automobile gearbox, is connected with gear change hand lever, is positioned at handle, at its lower end, stirs middle change pulley, and I/O rotating ratio is changed.If the shift fork on lathe is for speed change, be mainly used in operating mechanism, the gear plectrum of 2 occlusions is come to be pushed on another one gear one of them gear that can slide on axle to obtain another speed again.Namely change the position of lathe shifting slide gear, realize speed change.Or be applied in the mechanism of the engagement of solenoidoperated cluthes, disconnection, thus control transverse direction or length feed.
Shift fork is structurally by being divided into jaw and fork pin, it is circular that shift fork pin is generally an open semi, jaw is a perforated pipe shape body, shift fork its jaw when applying connects for connecting firmly with driving shaft clip, need at present on jaw, drill radial hole in the production process of shift fork, because the shape of shift fork is completely square not whole, drilling machine is not easy carry out clamping position accurately, crudy is difficult to keep stable.
Summary of the invention
The invention is intended to provide a kind of shift fork boring grab, to realize the accurate location to shift fork boring, improve crudy.
Shift fork boring grab in this programme, comprise clamp body, clamp body is provided with the apotting spindle for being located in jaw hole, clamp body is provided with the cotter pilotage for being positioned between shift fork fork pin, the both sides of cotter pilotage are provided with and pitch in pin along the arcwall face mated, clamp body is also provided with the clamp for upwards compressing jaw, clamp is positioned at immediately below cotter pilotage, clamp body is hinged with the bushing plate for being resisted against below jaw, on bushing plate, thread connection has lock-screw, the tail end of lock-screw through bushing plate and thread connection on clamp body, collared hole on bushing plate is between cotter pilotage and clamp, cotter pilotage, collared hole, apotting spindle, the geometric center conllinear from top to bottom of clamp.
The feature of technique scheme is: the location being achieved fork pin by cotter pilotage, apotting spindle ensure that shift fork is in correct Working position, shift fork clamps by clamp, bushing plate is resisted against after on jaw and carries out realization boring location, the drill bit of drilling machine can by the radial bore of collared hole at jaw, cutting force during boring is little, can realize stable boring work.
Further, clamp is rotating eccentric wheel, and eccentric wheel is for wedging in the groove on workpiece the location and clamping that realize workpiece.
Further, be provided with support nail between bushing plate and clamp body, support nail thread connection is on clamp body.The restraining position of bushing plate can be changed by the height adjusting support nail.
Further, cotter pilotage is detachably connected in clamp body.Different cotter pilotages can be selected according to the shift fork of different size, realize various applicability of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is that A-A in embodiment of the present invention Fig. 1 is to schematic diagram.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: cotter pilotage 1, lock-screw 2, bearing pin 3, bushing plate 4, support nail 5, apotting spindle 6, dies holder 7, eccentric wheel 8, clamp body 9.
Embodiment is substantially as shown in accompanying drawing 1,2: shift fork has been positioned in clamp body 9 by stable.The fork pin of shift fork upper, jaw under.Be embedded with cotter pilotage 1 between fork pin, cotter pilotage 1 is mounted in clamp body 9 by finger setting, and the both sides of cotter pilotage 1 are close to the interior edge of fork pin.
The jaw hole of shift fork is located on apotting spindle 6, and apotting spindle 6 to be located in clamp body 9 and to be fixed by nut.The below of jaw is an eccentric wheel 8, and eccentric wheel 8 is rotatably connected on clamp body 9, and can order about its handle with one, rotates clockwise handle and eccentric wheel 8 can be made to clamp jaw.
Also bushing plate 4 is hinged with by bearing pin 3 in the left side of clamp body 9, on bushing plate 4, thread connection has lock-screw 2, the tail end of lock-screw 2 is resisted against the upper surface of clamp body 9, the turn lock-screw 2 i.e. position of lockable bushing plate 4, ensures its in the course of the work stable.Below bushing plate 4, be also provided with the support nail 5 of thread connection on dies holder 7, dies holder 7 and clamp body 9 are fixedly connected.The height of adjustment support nail 5, can change bushing plate 4 extreme lower position, improves the flexibility of equipment.Just in time tangent with jaw after bushing plate 4 falls, the collared hole on bushing plate 4, just to the machining position in hole, and then just can implement drilling operating.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and/or 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 structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.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.
