Abstract
The invention discloses a split-structure key pulling fixture, solving the problems of the entire structure of a large-aperture key pulling fixture. The scheme is as follows: the split-structure key pulling fixture comprises two semi-circular positioning shafts (1) and a positioning block (3) clamped between the two semi-circular positioning shafts (1); key slots (4) are formed between the two semi-circular positioning shafts (1) and on the positioning block (3); the thickness of the positioning block (3) is 12mm+/-0.005 mm; the diameter of the two semi-circular positioning shafts (1) after closed is shown in the specification, and the degree of symmetry of the key slots (4) is 0.005 mm; the two semi-circular positioning shafts (1) and the positioning block (3) are screwed up by a bolt B (6) and a locating pin (10) to form a guide sleeve (8); and the guide sleeve (8) is fixed on a fixture body (5) by a bolt A (2). A broach (9) is put into the key slot (4); a workpiece (7) is mounted on the axle diameter of the two semi-circular positioning shafts (1), and the end surface of the workpiece (7) closely leans on the fixture body (5); and the broach (9) is started to move axially, and a blade cuts the workpiece (7) to pull out the key slots. The invention has delicate structure and high processing precision, and is convenient and fast to operate.
Description
Technical field
The present invention relates to the machining anchor clamps, be specifically related to a kind of minute body structure and draw the key anchor clamps.
Background technology
Engine horsepower constantly increases in recent years, and engine timing gear module and interior hole dimension also increase thereupon.The high efficiency processing method of gear inner hole key slot is drawn key exactly, and the small-bore draws the key anchor clamps generally to adopt the overall structure pattern, and the anchor clamps one end diameter of axle is connected with the broaching machine spindle hole, and the other end is the workpiece locating shaft.Workpiece will be contained on the anchor clamps with the endoporus location during processing keyway, broaching tool moves in the clamp body gathering sill, and the workpiece endoporus is drawn out keyway.The large aperture draws the key anchor clamps to adopt overall structure form, and the symmetry of gathering sill is difficult to guarantee in the 0.005mm tolerance; Draw strong anchor clamps to manufacture the comparison difficulty, and be difficult to guarantee design accuracy, expend a large amount of man power and materials.
Summary of the invention
The present invention discloses a kind of minute body structure and draws the key anchor clamps, to solve the problem that the large aperture draws key anchor clamps overall structure to exist.For addressing the above problem the following scheme of concrete employing:
Divide body structure to draw the key anchor clamps to form by two semicircle locating shafts (1) and the locating piece (3) that is clipped in wherein.
Described two semicircle locating shafts (1) and locating piece (3) are tightened with bolt B (6) and alignment pin (10), constitute a fairlead (8).
Described fairlead (8) is fixed on the clamp body (5) with bolt A (2), forms the split type key anchor clamps that draw of a cover.
Between described two semicircle locating shafts (1), the top of locating piece (3) forms keyway (4).
Described locating piece (3) size 12mm ± 0.005mm, the synthetic back of two semicircle locating shafts (1) diameter is
Keyway (4) symmetry 0.005mm.
The present invention is helpful to be: delicate structure, simple operation, machining accuracy height.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is that the branch body structure draws the key anchor clamps to face structural representation;
Fig. 2 is that the branch body structure draws key chuck side TV structure schematic diagram.
Among the figure: semicircle locating shaft 1, bolt A2, locating piece 3, keyway 4, clamp body 5, bolt B 6, workpiece 7, fairlead 8, broaching tool 9, alignment pin 10.
The specific embodiment
As shown in Figure 1 and Figure 2, divide body structure to draw the key anchor clamps to form by two semicircle locating shafts 1 and the locating piece 3 that is clipped in wherein; With bolt B 6 and alignment pin 10 two semicircle locating shafts 1 and locating piece 3 are tightened, constituted a fairlead 8; Locating piece 3 size 12mm ± 0.005mm, two semicircle locating shafts, 1 synthetic back diameter is
Keyway 4 symmetry 0.005mm; 8 usefulness bolt A2 are fixed on the clamp body 5 with fairlead, form the split type key anchor clamps that draw of a cover.
At first anchor clamps are fitted on the positioning disk of broaching machine front in the operation, broaching tool 9 are put in the keyway 4 of fairlead 8, adjust the height dimension of broaching tool 9 with pressing plate; Workpiece 7 is installed on the diameter of axle of two semicircle centration axis 1, end face is pressed the lathe switch then by tangible clamp body 5, and broaching tool 9 begins to move axially, and the blade cutting workpiece is pulled out a keyway at workpiece 7 internal diameters.
Claims (6)
