Description
Technical field
The utility model relates to a kind of special fixture, particularly a kind of clamp body of shift fork special fixture.
Background technology
Along with social development, science and technology is progress constantly, development of manufacturing also very rapid; What require also to become very in the process of finished parts is strict, no matter is all must have suitable fixture at drilling operating or milling flat etc., designs suitable fixture and not only ensure that part processing precision also improves operating efficiency; Therefore jig Design is a key component in manufacture process.In the processing of shift fork, the putting position of shift fork in lathe is very important, and the angle of putting is wanted accurately, can not loosen, the machining accuracy of such guarantee shift fork and working (machining) efficiency after clamping; Therefore the design of shift fork clamp is just very crucial; In order to ensure crudy and the working (machining) efficiency of shift fork, now provide a kind of clamp body.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design at this, and structure is simple, can preserve the fork special fixture clamp body of shift fork machining accuracy and lifting shift fork working (machining) efficiency.
The utility model realizes like this, shift fork special fixture clamp body described in the utility model, clamp body front end is provided with two circular holes, and on two circular holes, location axle pin is installed, two V-shaped grooves are provided with above clamp body, be rectangular channel bottom V-shaped groove, the gap be provided with between two V-shaped grooves; Clamp body rear end is a platform, and platform offers screwed hole and fore-set installing hole, and screwed hole is for installing double threaded screw, and fore-set installing hole is for installing fore-set; Offer six installing holes in clamp body bottom, six installing holes are distributed in clamp body low side both sides and every side distributes three, and installing hole is used for the screw of the connection of the concrete and lathe of mounting clamp.Gap between two V-shaped grooves is used for placed shifting fork leg, after placing shift fork leg, utilize the location axle pin be arranged on circular hole and big nut, and flat shim a and flat shim c coordinates the restriction shift fork leg left and right free degree; Utilize location axle pin middle circle cambered surface and shift fork inboard leg arc surface to fit simultaneously and limit shift fork Anterior-Posterior.
According to clamp body described in the utility model, location axle pin is cylinder pivot pin, mid portion axial plane and shift fork inboard leg cambered surface are fitted, and location axle pin two ends are provided with external screw thread, all big nut is installed at two ends, one end big nut joint jig body, is provided with flat shim a between other end big nut and clamp body.Utilize the big nut at location axle pin two ends to produce pretightning force thus limit the shift fork leg be placed in the middle of two V-shaped grooves.
The utility model has as follows a little:
Advantage one: the utility model structure is simple, reasonable in design, installs and easily manufactured, and the reliability of clamping shift fork is high, ensure that the working (machining) efficiency of shift fork crudy and raising shift fork.
Advantage two: the utility model offers two V-shaped grooves and two circular holes on clamp body, and V-shaped groove defines the placement location of shift fork, the location axle pin that two circular holes are installed controls shift fork four frees degree; And utilize the gap placed shifting fork leg between two V-shaped grooves; Although simplicity of design still meets the positioning requirements of shift fork.
Advantage three: this uses novel low cost of manufacture, dismounting and easy to maintenance; In the processing of shift fork, play key effect, be applicable to promoting the use of.
