Description
Technical field
The present invention relates to drilling machine technical field, particularly Multifunctional drill taper shank cover.
Background technology
Drilling machine is when processing plurality of specifications endoporus machine components, need the drill bit changing dimension according to the size in aperture, in the middle of one-stop operation, operator often will the drill bit of clamping different size and kind on acorde bur chuck continually, screw tap, the cutters such as reamer, cause that production efficiency is lower and operator's physical demands is also larger, in existing process technology, quick chuck is all interior taper shank interconnection system or adds standard drill chuck with standard Morse taper shank, former structure is large compared with complicated manufacture difficulty, the latter requires great effort again with standard drill chuck acquisition expenses is large and mounting cutter is consuming time, get half the result with twice the effort, have impact on operating efficiency.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, it is convenient to change, and can exit separately the Multifunctional drill taper shank cover that drill bit can exit again drill bit and tapered sleeve simultaneously.
Realize technical scheme of the present invention as follows:
Multifunctional drill taper shank cover, comprise tapered sleeve, be provided with the tailstock of the first cavity and the second cavity, tailstock body, leading screw, ejector pin and clamping device, described tapered sleeve is provided with the cavity inserted for drill bit, tapered sleeve is inserted in the first cavity of drilling machine tailstock, tapered sleeve is set to T-shaped structure, the less one end of tapered sleeve diameter is provided with can the clamping device of fixed drill bit, leading screw is provided with in second cavity, dividing plate is provided with between first cavity and the second cavity, dividing plate is provided with ejector pin, ejector pin end is provided with steady pin, tailstock is sheathed in tailstock body, tailstock body is provided with the handle controlling leading screw and seesaw.
Described clamping device comprises front outer ring, rear outer ring and chock, front outer ring sleeve is located on tapered sleeve, connected by spring between front outer ring and tapered sleeve, rear outer ring is by the solid end at tapered sleeve in chock top and front outer ring coordinates connected, and in order to coordinate the tapered sleeve end that acts on of spring to be fixed with limited step, advantage forms cavity between limited step and front outer ring, spring can realize the effect of Tension and Compression in cavity, namely promotes front outer ring and is the effect that front outer ring resets.
The contact surface that chock is connected with rear outer ring with front outer ring is inclined-plane, advantage be convenient to chock slip thus reach compress and unclamp drill bit.
The maximum gauge of described clamping device is less than the minimum diameter of tailstock, and advantage is the useful effect being convenient to clamping device, prevents it to be stuck and ineffective.
Described ejector pin and steady pin are structure as a whole, and advantage simplifies structure.
Have employed above-mentioned scheme, by the chock clamping in clamping device in the cavity that drill bit inserts tapered sleeve, chock is compressed by front outer ring and rear outer ring, so in the course of the work can not landing, structure be simple and stable; Tapered sleeve is set to the normal use that T-shaped structure is conveniently clamping device, and the path that clamping device is arranged on tapered sleeve can normally work, unaffected; Leading screw is moved forwards, backwards by the control of handle, and promote ejector pin, ejector pin acts on clamping device, makes clamping device work, and steady pin prevents ejector pin from coming off and dividing plate, causes clamping device to work; Structure is simple, and operating efficiency is high, and by leading screw, the cooperation of ejector pin and clamping device, can make separately drill bit exit and drill bit and tapered sleeve can be made simultaneously to exit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of clamping device in the present invention;
In accompanying drawing, 1 is tailstock, and 2 is tapered sleeve, and 3 is front outer ring, and 4 is chock, and 5 is rear outer ring, 6 is spring, and 7 is limited step, and 8 is leading screw, and 9 is handle, and 10 is ejector pin, and 11 is steady pin, 12 is dividing plate, and 13 is tailstock body, and 14 is the first cavity, and 15 is the second cavity, and 16 is drill bit.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1 and Fig. 2, Multifunctional drill taper shank cover, comprise tapered sleeve 2, be provided with the tailstock 1 of the first cavity 14 and the second cavity 15, tailstock body 13, leading screw 8, ejector pin 10 and clamping device, described tapered sleeve 2 is provided with the cavity inserted for drill bit 16, tapered sleeve 2 is inserted in the first cavity 14 of drilling machine tailstock 1, tapered sleeve 2 is set to T-shaped structure, the less one end of tapered sleeve 2 diameter is provided with can the clamping device of fixed drill bit 16, leading screw 8 is provided with in second cavity 15, dividing plate 12 is provided with between first cavity 14 and the second cavity 15, dividing plate 12 is provided with ejector pin 10, ejector pin 10 end is provided with steady pin 11, ejector pin 10 and steady pin 11 are structure as a whole, structure can be simplified, tailstock cover 1 is located in tailstock body 13, tailstock body 13 is provided with the handle 9 controlling leading screw 8 and seesaw, tailstock body 13 also can be offered lubrication groove (for marking in figure), ensure the normal operation of screw mandrel.
Described clamping device comprises front outer ring 3, rear outer ring 5 and chock 4, front outer ring 3 is sheathed on tapered sleeve 3, connected by spring 6 between front outer ring 3 and tapered sleeve 2, rear outer ring 5 is pushed up the solid end at tapered sleeve 2 by chock 4 and is coordinated with front outer ring 3 and is connected, front outer ring 3 outer surface is provided with bayonet socket, be convenient to rear outer ring 4 promoted, limited step 7 is fixed with in order to coordinate the tapered sleeve end that acts on of spring, advantage forms cavity between limited step 7 and front outer ring 3, spring 6 can realize the effect of Tension and Compression in cavity, namely promote front outer ring 3 and be the effect that front outer ring 5 resets.
The contact surface that chock 43 is connected with rear outer ring 5 with front outer ring is inclined-plane, advantage be convenient to chock 4 slip thus reach compress and unclamp drill bit 16.
The maximum gauge of described clamping device is less than the minimum diameter of tailstock, and advantage is the useful effect being convenient to clamping device, prevents it to be stuck and ineffective.
More during bit change, turning handle, makes leading screw travel forward, promote ejector pin, ejector pin withstands rear outer ring and produces thrust, outer ring after promoting, then after, outer ring drives front outer ring to move forward, and now, chock loosens, no longer drill bit is had to an effect of clamping, so just can more bit change, rotating backward handle, leading screw is away from ejector pin, and ejector pin loses thrust, and front outer ring automatically resets under the action of the spring, chock clamps drill bit again, namely completes bit change-over operation; If need unload whole for tapered sleeve, only need be rotated further handle, ejector pin promotes clamping device, till whole tapered sleeve is pushed out.
