Abstract
The utility model discloses an inverted cambered surface clamp which comprises a base (1). The center of the base (1) protrudes outwards to form a cylindrical positioning body (2), and the center of the positioning body (2) and the center of the base (1) are provided with center holes (3) which are communicated. A pull rod (4) is arranged in the center holes (3) in a penetrating mode, and the two ends of the pull rod (4) penetrate out from the outer side of the base (1) and the outer side of the positioning body (2) respectively, and the end of the side, close to the positioning body (2) of the pull rod (4) is provided with a pressure head (5). The pull rod (4) is further provided with a pressing block (8) in a sleeved mode, and the pressing block (4) is located between the pressing head and the positioning body (2). In addition, the pressing block (8) is provided with a notch (8a) extending outwards from the center. According to the inverted cambered surface clamp, the pull rod is matched with the pressing block, a workpiece can be more conveniently pressed, and meanwhile, an outer spline hub is adopted so that the inverted cambered surface clamp can be applicable to workpieces of more sizes. Furthermore, the inverted cambered surface clamp has the advantages of being firm in clamping, easy to operate, low in cost and the like.
Description
Technical field
The utility model relates to mechanical field, particularly relates to the pawl wheel cambered surface fixture on a kind of circular arc chamfering machine.
Background technology
In order to prevent that gear is when meshing, the end face wedge angle of gear is due to stressed excessive crumbling, conventionally need to carry out circular arc chamfering to the transverse profile of gear, and while gear being carried out to chamfering on radiusing machine, gear need to be clamped and guarantee that gear can not rotate freely when chamfering simultaneously, need to design special fixture for this reason gear is clamped, because radiusing machine itself possesses pull bar, therefore need to centered by pull bar, design a kind of fixture.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fixture that clamps gear when to gear face rounding cambered surface.
The technical solution of the utility model is as follows: a kind of inverted arc face fixture, comprise pedestal (1), the center outwardly convex of described pedestal (1) forms columniform positioning body (2), this positioning body (2) and pedestal (1) center are provided with the centre bore (3) communicating, in described centre bore (3), be equipped with pull bar (4), stretch out from pedestal (1) outside and positioning body (2) outside respectively at the two ends of this pull bar (4), and this pull bar (4) is provided with pressure head (5) near a side end of positioning body (2), on described pull bar (4), be also set with briquetting (8), this briquetting (8) is positioned between pressure head and positioning body (2), and this briquetting (8) has the therefrom outward extending breach of the heart (8a).
Use said structure, the pedestal of this fixture is arranged on radiusing machine, by pull bar to radiusing machine, after taking off briquetting, workpiece is nested on pull bar through pressure head, briquetting is nested on pull bar again, makes briquetting between workpiece and pressure head, last driven wheel beveler drives pull bar retraction, thereby pressure head on pull bar is pressed onto on the end face of briquetting Work-sheet pressing, makes workpiece make can not rotate freely in chamfering.
Because inner hole of workpiece has internal spline, on described pull bar (4), be set with external splines cover (6), this external splines cover (6) is positioned between pressure head and positioning body (2).Workpiece is nested into external splines and puts, the contact area of more enough increase workpiece and pull bar, further prevents workpiece rotation, changes spline housing simultaneously, can adapt to the workpiece of different size.
The outer circumference surface of described pedestal (1) offers open slot, is inserted with tool setting plate (8) in this open slot.During use, the one end by this to knife plate is inserted in open slot, and the other end extend in the teeth groove of workpiece, and more enough assurance gears can not rotate freely.
Beneficial effect: the utility model has adopted coordinating of pull bar and briquetting, and more enough workpiece pressings easily adopts external splines cover can adapt to the workpiece of more sizes simultaneously, also has the features such as firm, simple to operate, with low cost that clamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of briquetting in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the utility model comprises pedestal 1, positioning body 2, pull bar 4, pressure head 5, external splines cover 6, the parts such as bolt 7 and briquetting 8, described pedestal 1 is arranged on radiusing machine by bolt, in the center of pedestal 1 outwardly convex, form columniform positioning body 2, this positioning body 2 and pedestal 1 center are provided with the centre bore 3 communicating, in described centre bore 3, be equipped with pull bar 4, stretch out from pedestal 1 outside and positioning body 2 outsides respectively at the two ends of this pull bar 4, and this pull bar 4 is provided with pressure head 5 near a side end of positioning body 2, on described pull bar 4, be also set with briquetting 8, this briquetting 8 is between pressure head and positioning body 2, and this briquetting 8 has the therefrom outward extending breach 8a of the heart.On described pull bar 4, kink is equipped with external splines cover 6, and this external splines cover 6 is between this briquetting 8 and positioning body 2.The outer circumference surface of described pedestal 1 offers open slot, is inserted with tool setting plate 8 in this open slot.
The foregoing is only preferred embodiment of the present utility model; not take the utility model as restriction; all any modifications of doing, be equal to the quantity etc. of replacing and improving as change dial framework and benchmark post, within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
Claims (3)
