The utility model content
In order to overcome the defective of prior art, a kind of convenient mounting and clamping, the anchor clamps that crudy is high, production efficiency is high are provided, the utility model discloses a kind of anchor clamps that are used for machining bearing lid on milling machine.
The utility model reaches goal of the invention through following technical scheme:
A kind of anchor clamps that are used for machining bearing lid on milling machine comprise base and pressing plate, it is characterized in that: also comprise alignment pin; The side of base has groove; The width of groove cross section notch is not more than the twice of groove section depth, and the both sides of groove notch edges have pin-and-hole, is inserted with alignment pin in the pin-and-hole; The symmetry axis of two alignment pins and the symmetry axis of groove overlap; Pressing plate is made up of two columns and a transverse slat, and two columns are vertically fixed on the two ends of transverse slat respectively, and the distance between two columns is not less than the width in groove cross section.
The described anchor clamps that are used for machining bearing lid on milling machine; It is characterized in that: the quantity of groove is 2~5, and the both sides of each groove notch edges all have pin-and-hole, and the cross section of groove is a rectangle; All be inserted with alignment pin in each pin-and-hole, the quantity of pressing plate and the quantity of groove equate.
The described anchor clamps that are used on milling machine machining bearing lid, it is characterized in that: alignment pin is selected the rhombus pin for use, and the distance between two columns is 100%~120% of a groove cross-sectional width.
When the utility model uses, with the bottom alignment base of bearing cap to be processed, the pin-and-hole that the left installing hole and the right installing hole of bearing cap both sides are aimed at the bottom plate groove both sides respectively; And fix with alignment pin, the top of bearing cap compresses with pressing plate, when pressing plate compresses; Make two columns of pressing plate push down the shoulder of both sides, bearing cap top respectively; Subsequently, the utility model of having fixed bearing cap to be processed is placed on the machine table of milling machine and clamping is fixed, boring cutter is installed on milling machine spindle; Regulate the boring cutter position and make it the center of circle that alignment bearings is covered semicircle bearing guard, can implement hole processing.
The utility model has utilized the fireballing advantage of milling machine main motion, convenient mounting and clamping, and process velocity is fast, and crudy is high, and can realize that a clamping processes a plurality of products, makes production efficiency bring up to part/order of classes or grades at school from original part/order of classes or grades at school.The beneficial effect of the utility model is: simple in structure, easy to use, crudy is high, and production efficiency is high.
