Description
Technical field
The utility model belongs to the field of machining, is specially a kind of clamp for machining with dead eye workpiece.
Background technology
When carrying out machining, during for the irregular structure of the workpiece that needs the machining bearing hole, particularly workpiece or more complicated, workpiece need be fixed, require high to fixing accuracy and accuracy, and majority is manual fixing at present, tighten with bolt is manual, and consuming time, effort and poor stability, backward in technique, the modern large-scale production of incompatibility causes waste to resources such as manpower and materials.For the patent No. is 200820035943.8 patent application, discloses a kind of lathe anchor clamps, and these anchor clamps have been realized mechanical fixing automatically, but the shortcoming of its existence is a complex structure, and it is big to take up room, and the dismounting inconvenience is lost time etc.
The utility model content
The purpose of this utility model is exactly that a kind of clamp for machining of being convenient to the processing work dead eye of dismounting use simple in structure is provided at the defective of above-mentioned existence.These anchor clamps adopt and comprise that the spiral pull bar of tie-plate, traverses fixed dish, this spiral tie rod end are fixed with pressing plate, the other end of this spiral pull bar is fixed on the arm-tie between tie-plate and the fixed disk, this arm-tie is fixedlyed connected with hydraulic pressure draw-bar by coupling nut, and described fixed disk center fixation has positioning disk; Be fixed with the ring-type coupling sleeve between tie-plate and fixed disk, this coupling sleeve excircle is provided with the technical scheme of square hole, and this clamp structure is simple, and weight is little, and is strong to the adaptability of processing work, and convenient disassembly is easy to use again.
The technical scheme of the utility model anchor clamps is: comprise that the spiral pull bar of tie-plate, traverses fixed dish, this spiral tie rod end are fixed with pressing plate, the other end of this spiral pull bar is fixed on the arm-tie between tie-plate and the fixed disk, this arm-tie is fixedlyed connected with hydraulic pressure draw-bar by coupling nut, it is characterized in that described fixed disk center fixation has positioning disk; Be fixed with the ring-type coupling sleeve between tie-plate and fixed disk, this coupling sleeve excircle is provided with square hole.
Characteristics of the present utility model also have, and described square hole is 3; Described pressing plate is 2; Described spiral pull bar is provided with guide pin bushing, and this guide pin bushing is fixed on the fixed disk; Described spiral pull bar tail end stretches out arm-tie, and this tail end is provided with the fixing nut of split pin, is set with spring on the spiral pull bar between nut and the arm-tie.
The beneficial effects of the utility model are: these anchor clamps have been realized automatic mechanical grip operation, reduce labour intensity, shorten the clamping time, on the excircle of coupling sleeve, be provided with square hole, the so i.e. bolt that connects with lathe of remover-and-replacer has very easily alleviated the weight of anchor clamps again; The fixed disk center fixation has positioning disk, and fixed disk is designed to hollow, just with the connector of dismounting coupling nut and arm-tie, reduces stand-by time; These anchor clamps do not have special-purpose lubricating system, it is little to take up room, and can leave for more space asymmetric and external form complex parts selection pressure point, makes clamping more reasonable, for lubricating of spiral pull bar, can adopt cutting fluid, because the rotation frequency of spiral pull bar is not high, the rotation amplitude is little, can satisfy lubricated needs fully, in a word, the utility model is simple in structure, and volume is little, in light weight, be convenient to dismounting and use, the transition of converted products is fast, is suitable for small lot, many kinds, in rolling clamp, the axial clamping of processing for non-regular shape workpiece has very strong representativeness, popularization and practicality.
