Description

Gear-box right boring hole tool
Technical field
The utility model relates to a kind of frock for gear-box right boring hole, belongs to the gear train assembly processing technique field.
Background technology
In commercial Application, when gear-box was carried out the right boring hole, the general process equipment that adopts was vertical machining centre, and processing content mainly contains large and small dead eye and the flange face of motor side and wheel side.The advantage of vertical machining centre is that centering frock easy, that use is simple, clamping stable.But because wheel side, the motor side of gear-box all needs processing, this structures shape its need to pass through twice clamping, process motor side respectively and wheel side realizes.Its shortcoming is: 1. owing to process at twice, centering has certain error, causes the axiality of large and small dead eye, and the depth of parallelism of flange face is relatively poor; 2. centering is time-consuming, and working (machining) efficiency is not high; 3. need to use two cover frocks.
In order to improve product quality, cut down finished cost, shorten the process-cycle, processing enterprise is constantly being explored always, and the precise boring of carrying out gear-box with horizontal Machining centers is a kind of effective mode, but needs the frock of design specialized to come place work piece; This frock need to satisfy following functions: 1. integrated design; 2. clamping is stable; 3. make workpiece stressed evenly, avoid workpiece deformation; 4. centering is convenient in accurate positioning; 5. modularized design, highly versatile; 6. compact conformation, light-weight design.
The utility model content
The purpose of this utility model is: the problem for above-mentioned prior art exists, a kind of gear-box right boring hole tool is proposed, and can not only clamping workpiece is stable, stressed even, also can greatly improve centering efficient by positioning element, shorten the process-cycle.
In order to reach above purpose, gear-box right boring hole tool of the present utility model comprises base plate, support and caging bolt seat, and at least two described supports are bolted and connect on the described base plate, and the top of described support is equipped with workpiece clamping mechanism; Described base plate between described support is equipped with at least two described caging bolt seats, and described caging bolt seat is provided with Limit screw.
Further restriction technical scheme of the present utility model: aforesaid gear-box right boring hole tool, described workpiece clamping mechanism comprises locating piece, bolt and nut, pressing plate and back-up block, described bolt vertically is fixedly connected on the top of described support, described locating piece and back-up block are located at respectively the both sides of described bolt, described locating piece is located at the side near workpiece, described pressing plate passes the top that described bolt places described locating piece and back-up block, is screwed with described nut on the bolt that described pressing plate stretches out.
Aforesaid gear-box right boring hole tool, described locating piece are provided with groove, screw thread alignment pin and the cylinder pin hole that cooperates with gear-box, cooperate the location by described screw thread alignment pin with described gear-box.
By tightening of pressing plate realized that frock is to the fixed function of gear-box workpiece above-below direction; The cooperating of cylinder pin hole on screw thread alignment pin and the tool locating piece realizes that frock is to the fast positioning function of the fixing and workpiece of workpiece left and right directions.
Aforesaid gear-box right boring hole tool is positioned on the described support of described workpiece clamping mechanism both sides and also is provided with a pair of caging bolt plate, in order to realize fore-and-aft direction (large dead eye is axial) fixing to gear-box.
Aforesaid gear-box right boring hole tool, described support and caging bolt seat and described base plate connecting bolt hole are the stay bolt hole; The workpiece that can make frock be applicable to vary in size with respect to the mobile adjustment of base plate by support.
Further, aforesaid gear-box right boring hole tool, described support is cuboid.
The beneficial effects of the utility model are: the utility model is comprised of simple part, is easy to assembling, and integrated design makes it be easy to use, handling; By rational deployment, can not only make clamping workpiece firm, the stress deformation that can also avoid clamping to produce; Use the screw thread alignment pin, make workpiece and frock Rapid matching, shortened the centering time; By modularized design, make frock have very strong versatility.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model uses view.
