Description
The utility model relates to electric jig saw, is a kind of incidence regulating mechanism of electric jig saw.
Existing electric jig saw incidence regulating mechanism includes the electric jig saw body, be positioned at the rotating base plate of body downside, linked by an arch support between the two and be fixed together, described arch support can rotate and lock with respect to the sweep-saw body, thereby between can form certain angle of inclination.But above-mentioned this to relatively rotate and lock be to rely on a double-screw bolt that is fixed with one with the sweep-saw body and one to screw from bottom to top the nut of arch support clamping cooperating each other realized.This fastening means has following shortcoming: at first be unreliable, nut may rotate under the vibration that is produced at motor and get loose; Next is that nut must be operated with instruments such as spanners when clamping, because described nut is to be positioned in the inner chamber of an arch support, the space is restricted, so very inconvenient when operating with spanner.
The purpose of this utility model is: a kind of easy to operate, firm sweep-saw inclination angle governor motion of locking is provided, it does not need to adopt instruments such as spanner when operation (unclamp or clamp), do not need too big latching force just can keep base plate tilt adjustment and the locking firm with respect to the sweep-saw body.
Scheme of the present utility model is: on sweep-saw body downside, uprightly be fixed with one can rotation fixed bolt, other has one and the separable base plate of sweep-saw body, the breach that passes through for saw blade at described base plate front end band, the outside, bottom surface (downside) of base plate is the plane, is fixed with the arch support of an arch on the upper side of base plate.Have a deep-slotted chip breaker that supplies described fixed bolt to pass through on the upside cylinder of described arch support.(inner chamber of arch support) has a fitting strip that is spirally connected mutually with described double-screw bolt below deep-slotted chip breaker.Be connected with one horizontally disposedly and with the degree of tightness knob that is used for the turn double-screw bolt of inclination angle locking on the end face of described double-screw bolt, described clamping plate sheet can progressively rise when described double-screw bolt turn described arch support is fixedly clamped.The flank profil of processed arc on the one end termination of described arch support is being moulded identical flank profil, both the chimeric lockings of formation mutually face to face that also process on the shell with the sweep-saw of described arc flank profil relative position.The scale that reflection inclination angle size is arranged on the upper side of described arch support.On described arch support upper side, also have the vertical straight trough that passes through for described double-screw bolt, it make base plate can do appropriateness vertically (with the direction of propulsion of sweep-saw in the same way) move, realize flank profil on the described arch support and sweep-saw mould on the shell flank profil each other tooth to the engagement or the disengaging of tooth.Body belly downside has the protruding counterfort face of a cancave cambered surface and described arch support to amplexiform mutually, and described base plate also can be locked on the position of any inclination with respect to body is rotatable.
The utility model has the advantages that: at first, sweep-saw is easy to operate when adjusting the angle of inclination, and only with hand turn double-screw bolt (by turn degree of tightness knob) just, does not need instruments such as actuating spanner.Secondly, do not need too big locking moment when the locking inclination angle, because be provided with the engagement of " tooth is to tooth " on arch support, under ingear lock-out state, its anti-loose energy force rate will not strengthen greatly with the scheme of engaging tooth.
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated.
Brief Description Of Drawings:
Fig. 1 is the general partial sectional view of an embodiment of the utility model;
Fig. 2 is the base plate stereogram of Fig. 1 embodiment;
Fig. 3 is the layout of looking up partial sectional view, reflection degree of tightness knob of Fig. 1;
Fig. 4 be the A-A of Fig. 1 to view, the general structure of reflection inclination-angle regulating device;
Fig. 5 is the inclination user mode figure of Fig. 4.
An embodiment of the present utility model is reflected in the accompanying drawing of Fig. 1 to Fig. 5, and Fig. 1 analyses and observe the overall formation that part has reflected an electric jig saw incidence regulating mechanism.Be fixed with a fixed bolt (2) that outwards stretches from the lining on the belly downside of electric jig saw body (1), its top is fixed with the degree of tightness knob (3) of a horizontally disposed turn double-screw bolt (2).Described double-screw bolt (2) role is to constitute a kind of each other separable be connected with the separable base plate of sweep-saw body (4) with body with one.Connection between the two also must be achieved by an arch support (5) and a fitting strip (6) that is fixed on the base plate (4).Body (1) belly downside has the protruding counterfort face of a cancave cambered surface and described arch support (5) to amplexiform mutually.Have for the curved groove (7) of the arc that passes through of double-screw bolt (2) on the upside cylinder of arch support (5), also have a vertical straight trough (8) and pass through for double-screw bolt (2), described arc bend groove (7) be when regulating the inclination angle of base plate (4) and body (1) for double-screw bolt (2) by usefulness; And described vertical straight trough (8) is to pass through to use for double-screw bolt (2) along the mobile of the sweep-saw direction of motion with respect to body (1) at base plate (4).At the processed dentation profile of an end of arch support (5) (9), mould relative with the profile of tooth (9) of arch support also processes identical profile of tooth on the shell face under the belly of body (1).When base plate (4) moves, when the profile of tooth (9) and the body (1) of arch support end are moulded on the shell corresponding profile of tooth contraposition engagement, just limited base plate (4) is done rotation with respect to whole (1) the free degree forward.On the upper surface of arch support (5), be carved with the scale graticule (10) that can reflect the inclination angle number of degrees.The front end of base plate (4) jagged (11), it passes through usefulness for saw blade (12).The saw blade carriage (13) of the belt wheel on the body (1) provides support at work for saw blade (12).
The course of work of the present utility model is as follows:
When needs are regulated the inclination angle, unclamp degree of tightness knob (3) earlier, make body (1) and base plate (4) get loose mutually, the inner chamber that does not need to extend into arch support (5) with spanner goes operation.After both get loose mutually, base plate (4) is rotated on the angle at the inclination angle of wanting, then base plate (4) is passed forward, profile of tooth on the arch support termination (9) and body (1) are moulded when corresponding profile of tooth is meshing with each other on the shell, again with the moving degree of tightness knob (3) of hand-screw, cause on the fitting strip (6) and open, arch support (5) is clamped on the body (1), and like this, base plate (4) just is fastened on the body (1) with a desired inclination angle.Base plate (4) is moved backward when with hand-screw pine knob (3) again, make the profile of tooth (9) of arch support (5) mould with body (1) that corresponding profile of tooth breaks away from engagement on the shell, this just makes base plate (4) be in the state that gets loose with respect to body (1).
