Abstract
The utility model relates to an unfolding/folding mechanism of a belt cover of a bench drill. The utility model is arranged between the belt cover and a selective headstock. The utility model comprises a lower hinged support seat which is fixed at the back of the upper surface of the selective headstock and is provided with a shaft hole, an upper hinged support seat which is fixed in the belt cover and is provided with a shaft hole, and a rectangular frame-shaped connecting rod shaft hinged between the upper hinged support seat and the lower hinged support seat. The upper side of the connecting rod shaft is hinged on the upper hinged support seat, and the lower side of the connecting rod shaft is hinged on the lower hinged support seat. The upper surface of the selective headstock is fixed with an inverted omega-shaped elastic clip. A support seat provided with a ball head is fixed in the belt cover. After the connecting rod shaft rotates to buckle the belt cover, the ball head of the support seat is just embedded into the elastic clip. The upper hinged support seat and the lower hinged support seat are respectively composed of a seat body provided with a half shaft hole, and a seat cover which is fixed on the seat body with a screw and is also provided with a half shaft hole. A tool does not need to be used, and the utility model can be operated by hand. The belt cover does not need to be aimed at the selective headstock on purpose, and the belt cover can be automatically aimed. The utility model has the advantages of simple operation, labor saving, time saving and high efficiency. The utility model can be used in various drill machines.
Description
Technical field
The utility model belongs to the bench drill technical field, more particularly relates to the improvement of the open-and-close mechanism of bench drill belt housing.
Background technology
The belt housing of tradition bench drill is installed on the headstock with screw.In the time of need opening, instruments such as need use screwdriver are backed out screw, belt housing are taken off again.When needing to install, need earlier belt housing to be fastened and aim at headstock, re-use screwdriver screw is tightened one by one.Just there is following shortcoming in this: need the tool using operation, need earlier belt housing to be fastened and aims at headstock, troublesome poeration, time-consuming.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of open-and-close mechanism of bench drill belt housing is provided.It does not need tool using, and free-hand can the operation need not fasten belt housing and the aligning headstock, and be simple to operate, saving of work and time efficient height.
In order to achieve the above object, the utility model is installed between belt housing and the headstock.It comprises the lower hinge support that is fixed on tape spool hole in rear portion above the headstock, be fixed on the upper hinge support in tape spool hole, belt housing the inside and be hinged on upper hinge support and lower hinge support between rectangular box-like pitman shaft.The top of pitman shaft is hinged on the upper hinge support, and the bottom of pitman shaft is hinged on the lower hinge support.
In the time that belt housing need being opened, need not use instruments such as screwdriver, as long as lift with the front portion of handgrip belt housing.So belt housing just can rotate up around the top of rectangular box-like pitman shaft, rectangular box-like thereupon pitman shaft integral body is rotated backward around lower hinge support, and belt housing rotates, erects the rear side that leans at headstock backward the most at last.In the time of need closing, do not need specially belt housing to be fastened,, just can aim at headstock automatically and close as long as belt housing is rotated down forward.Simple to operate, saving of work and time.
Fixing the resilient clip of a shape of reverse omega above the headstock, a bearing that has bulb is being fixed in the belt housing the inside.After the pitman shaft rotation fastened belt housing, the bulb of bearing just embedded in the resilient clip its locking.This structure can guarantee to fasten and accurately put in place.In the time of need opening belt housing, firmly bulb is deviate from from resilient clip gently, simple, reliable.
Upper hinge support and lower hinge support are by the pedestal that has the semiaxis hole and be fixed on the flap that has the semiaxis hole on the pedestal equally with screw and formed.This structure can make the installation of upper and lower hinged-support and pitman shaft simplify.That is in the semiaxis hole of the pedestal of earlier pitman shaft being packed into, flap be fixed on the pedestal with screw get final product good manufacturability again.
About upper hinge support and lower hinge support respectively have two.About the spacing of two upper hinge supports and lower hinge support bigger, the stability that this structure can strengthen they and pitman shaft after installing.
Task of the present utility model comes to this and finishes.
The utility model does not need tool using, and free-hand can the operation need not specially be aimed at headstock to belt housing, can aim at automatically, and be simple to operate, saving of work and time efficient height.It can be widely used in the various drilling machines.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 inserts the schematic diagram that is locked in the resilient clip for bulb.
The specific embodiment
Embodiment 1.A kind of open-and-close mechanism of bench drill belt housing, as depicted in figs. 1 and 2.It is installed between the belt housing 1 and headstock 2 of bench drill.Comprise the lower hinge support 3 that is fixed on rear portions above the headstock 2 and tape spool hole, be fixed on the upper hinge support 4 in tape spool hole, belt housing 1 the inside and be hinged on upper hinge support 4 and lower hinge support 3 between rectangular box-like pitman shaft 5.The top of pitman shaft 5 is hinged in the upper hinge support 4, and the bottom of pitman shaft 5 is hinged in the lower hinge support 3.6 is the column of bench drill, and 7 is its base.
Fixing the resilient clip 8 of a shape of reverse omega above the headstock 2, a bearing 10 that has bulb 9 is being fixed in belt housing 1 the inside.When pitman shaft 5 be rotated down forward fasten to belt housing 1 on the headstock 2 after, the bulb 9 of bearing 10 just embeds in the resilient clip 8.
Upper hinge support 4 and lower hinge support 3 are by the pedestal 11 that has the semiaxis hole and be fixed on the flap 12 that has the semiaxis hole on the pedestal 11 equally with screw and formed.
About upper hinge support 4 and lower hinge support 3 respectively have two.
Embodiment 1 does not need tool using, and free-hand can the operation need not specially be aimed at headstock to belt housing, can aim at automatically, and be simple to operate, saving of work and time efficient height.It can be widely used in the various drilling machines.
