Abstract
The utility model provides a flange centering frock relates to flange drilling processing frock field, including vertical set up etc. Mainboard, the bottom plate at high post and the upper and lower both ends of height post such as being fixed in respectively, the bottom plate upper end is fixed with the hydro -cylinder, install the lever pressure arm on the mainboard, the even ring of lever pressure arm is established threely, and the upper end inboard of every lever pressure arm all is provided with the alloy briquetting, and the lower extreme of three lever pressure arm is respectively through the same hydro -cylinder connector of hinged joint, the hydro -cylinder connector is fixed on the piston rod of hydro -cylinder, the middle part of lever pressure arm is rotated through the lever round pin and is installed on the mainboard. The utility model provides a flange centering frock for self -holding is realized through the steerable lever pressure arm of hydro -cylinder to the clamping flange, and structural design is simple, operating maintenance is convenient.
Description
Technical field
The utility model relates to flange drilling processing tool field, particularly relates to a kind of flange centering frock.
Background technology
The existing frock clamp for flange centering, uses common ￠ 200 standard manual chuck, and clamping and unclamping needs to use chuck handle, and labour intensity is high, and the clamping time is long.
Utility model content
The purpose of this utility model is to provide a kind of flange centering frock, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of flange centering frock, it is characterized in that: comprise the contour post longitudinally arranged and the mainboard, the base plate that are individually fixed in the upper and lower two ends of contour post, described base plate upper end is fixed with oil cylinder, described mainboard is provided with lever pressure arm, described lever pressure arm uniform ring establishes three, alloy briquetting is provided with inside the upper end of each lever pressure arm, the lower end of three lever pressure arms is respectively by the same oil cylinder connector of chain connection, described oil cylinder connector is fixed on the piston rod of oil cylinder, and the middle part of described lever pressure arm is rotatably installed on mainboard by lever pin.
Mainboard, base plate are fixedly connected with contour post respectively by bolt, dismounting, easy to assembly.During work, the piston rod of oil cylinder pulls downwards, oil cylinder connector drives the action simultaneously downwards of three hinges to drive three lever pressure arms to rotate centered by lever pin simultaneously, the upper end of three lever pressure arms is inwardly tightened up simultaneously, workpiece (flange) clamping keeps not spinning by the alloy briquetting arranged inside lever pressure arm upper end, after realizing clamping, starts processing, oil cylinder upwards action after work pieces process completes, unclamps the clamping force of lever pressure arm to workpiece.
Described alloy briquetting is made up of kirsite, the seal face of alloy briquetting is provided with continuous print lug boss.
Described lug boss is the setting of arc convex or tapered protrusion, continuous print lug boss, can well mounting flange, simultaneously when carrying out centering to flange, the vibrational energy that drill bit produces can be absorbed, reduce the frequency of broken drill, improve the crudy of centre bore.
Described connector comprises columniform connecting portion, and described swivel hook is located at around this connecting portion, and described connector also comprises piston rod connecting portion, and this piston rod connecting portion is fixing by being threaded in piston rod.
Alloy briquetting is bolted on lever pressure arm upper end, by loosening spiral, can regulate the installation site of alloy briquetting on lever pressure arm, thus regulates alloy to the arm of force of Work-sheet pressing, to realize regulating thrust.
The beneficial effects of the utility model are:
The flange centering frock that the utility model provides, for clamping flange, can control lever pressure arm by oil cylinder and realize Automatic-clamping, and structural design is simple, and operating maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the clamping schematic diagram of alloy briquetting to workpiece.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiments and the drawings, further elaboration the utility model, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
As Fig. 1, shown in Fig. 2, a kind of flange centering frock, comprise the contour post 2 longitudinally arranged and the mainboard 5 being individually fixed in contour post about 2 two ends, base plate 1, base plate 1 upper end is fixed with oil cylinder 10, mainboard 5 is provided with lever pressure arm 4, lever pressure arm 4 uniform ring establishes three, alloy briquetting 7 is provided with inside the upper end of each lever pressure arm 4, the lower end of three lever pressure arms 4 connects same oil cylinder connector 3 respectively by hinge 9, oil cylinder connector 3 is fixed on the piston rod of oil cylinder 10, the middle part of lever pressure arm 4 is rotatably installed on mainboard 5 by lever pin 6, workpiece 8 is gripped by three alloy briquettings 7.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description is only preference of the present utility model; be not used for limiting the utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
