Abstract
The utility model relates to a floating type fine lapping fixture, which is characterized by comprising a bottom plate, a steel ball retaining plate, a connecting plate, a press plate and steel balls. The steel ball retaining plate and the connecting plate are sequentially arranged on the upper surface of the bottom plate and connected to form a floating integral body by rivets, a press plate mechanism is disposed at the center of the connecting plate, cylindrical holes are transversely disposed on the steel ball retaining plate at intervals and are close to two ends of the steel ball retaining plate, the steel balls are arranged in the cylindrical holes, and the thickness of the steel ball retaining plate is smaller than the diameter of each steel ball. The floating type fine lapping fixture has the advantages that when the floating type fine lapping fixture is used for lapping a hole of a part with higher requirements for perpendicularity of hole surfaces, the part can float along with a tooling after being fixed onto the tooling, the perpendicularity of a processed hole is qualified, qualification rates of dimension accuracy and perpendicularity accuracy are greatly increased as compared with those of a previous traditional tooling, the qualification rate of the dimension accuracy is increased by more than 50%, and the qualification rate of the perpendicularity accuracy of the hole surfaces is improved by more than 1.5 times.
Description
Technical field
The utility model belongs to frock clamp, relates in particular to a kind of floating type lappingout hole anchor clamps.
Background technology
During hole that lappingout precision component hole face vertical precision is had relatively high expectations; Adopt screw or pressing plate to clamp at present; Though this locate mode is simple, has wretched insufficiency: the mode workpiece that tradition leans on screw or pressing plate to be fixed can not move, porting add hole face off plumb situation appears man-hour and can not automatic capturing; Hole after causing processing is vertically defective, and percent defective is high.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of floating type lappingout hole anchor clamps to be provided, and the precision component that hole face vertical precision is had relatively high expectations adopts the lappingout processing mode that floats, and has improved product percent of pass.
The utility model is for realizing above-mentioned purpose; Realize that through following technical scheme a kind of floating type lappingout hole anchor clamps is characterized in that: comprise base plate, steel ball holding plate, connecting plate, pressing plate and steel ball; Said plate upper surface is equipped with steel ball holding plate and connecting plate successively; And connect into through blind rivet and to float wholely, connecting plate central authorities are provided with press plate mechanism, and said steel ball holding plate is provided with cylindrical hole near the lateral separation, two ends; Be equipped with steel ball in the said cylindrical hole, said steel ball holding plate thickness is less than diameter of the steel ball.
Said press plate mechanism comprises pressing plate, screw and adjusting jackscrew, and said pressing plate centre bore runs through screw, and said screw and connecting plate are spirally connected, the pressing back-end adjusting jackscrew that is spirally connected.
Said connecting plate is provided with shop bolt.
Beneficial effect: during hole that the lappingout part is vertically had relatively high expectations to the hole face; Guarantee that part can float with frock after fixing on the frock; Guarantee that the hole perpendicularity after the processing is qualified; Dimensional accuracy and vertical precision qualification rate have all had large increase than preceding traditional frock, and wherein the dimensional accuracy qualification rate improves more than 50%, and hole face vertical precision qualification rate improves more than 1.5 times.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with preferred embodiment; Details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of floating type lappingout hole anchor clamps comprise base plate 1, steel ball holding plate 2, connecting plate 3, pressing plate 5 and steel ball 9; Said plate upper surface is equipped with steel ball holding plate and connecting plate successively; And connect into through two parallel blind rivets 8 and to float wholely, connecting plate central authorities are provided with press plate mechanism, and said steel ball holding plate is provided with four or above cylindrical hole near the lateral separation, two ends; Be equipped with steel ball in the said cylindrical hole, said steel ball holding plate thickness is less than diameter of the steel ball.Said press plate mechanism comprises pressing plate 5, screw 6 and regulates jackscrew 7, and said pressing plate centre bore runs through screw 6, and said screw and connecting plate are spirally connected, the pressing back-end adjusting jackscrew that is spirally connected.Said connecting plate is provided with shop bolt 4.
Operation principle
After a frock parts were connected by above-mentioned annexation, workpiece was fixed on the connecting plate by pressing plate, lean on steel ball and the gap between the steel ball holding plate to realize floating of all directions during the processing porting, thereby the vertical precision requirement of metapore face is processed in assurance.
The course of work
(1) workpiece is fixed on the connecting plate by the pin direction
(2) lean on screw belt dynamic pressure plate workpiece pressing
(3) guarantee that connecting plate is with the processing free floating during porting
(4) unload workpiece and accomplish porting processing
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
