Abstract
The utility model relates to a quick-change output axle housing, particularly a quick-change output axle housing capable of changing a drill bit inside in advance and inserting and covering the drill bit on an output shaft, which is used as a fitting of a quick-change drill bit of the output shaft of a drill press multi-axle device. The utility model is characterized in that the quick-change output axle housing comprises a quick-change joint; the quick-change joint is provided with a shaft insertion hole at the top end, and can be inserted in and covered on the shaft insertion hole; the other end of the quick-change joint is provided with a drill bit insertion hole concentric with the shaft insertion hole; the side wall of the quick-change joint is provided with a through hole capable of connecting with the output shaft by a pin sleeve; a sliding sleeve with a spring and a group of steel balls are arranged between the quick-change joint and the output shaft, wherein the steel balls can move in the sliding sleeve and can be clamped in a groove on the side wall of the output shaft so as to realize the axial quick positioning of the quick-change joint on the output shaft. As a result, the utility model can solve the problems that loading and unloading for the change of the drill bit of the output shaft of the existing drill press multi-axle device is required to carry out on the output shaft directly when the drill press stops, the problems of the drill press multi-axle device always occur, etc.
Description
Technical field
The utility model relates to a kind of accessory that is used for the quick change drill bit of drilling machine multi-shaft device output shaft, the especially a kind of quick-changing type output sleeve of moment sleeve to the output shaft that can change the outfit drill bit in advance within it and shut down.
Background technology
Existing drilling machine multi-shaft device output shaft, its structure can see from Fig. 4, and the top of output shaft 1 directly is fixed on the housing of multi-shaft device, in the bottom with a slotting drill bit bore that can clamp drill bit.The shortcoming of existing this output shaft is; Because of it and the affixed one of multi-shaft device housing; so the transposing drill bit loading and unloading all must when drilling machine is shut down, directly on output shaft, carry out, more time-consuming; not only because the quantity of drilling machine multi-shaft device is many, bit change but also frequently more; therefore it is long that the time that drill bit spent is changed in shutdown, causes the production efficiency of drilling machine low.
Summary of the invention
The utility model is will overcome existing drilling machine multi-shaft device output shaft because of bit change long shortcoming downtime; provide a kind of and can change drill bit in advance within it and at the quick-changing type output sleeve of quick sleeve of the moment of drilling machine multi-shaft device stall to the output shaft, and make it have simple and reasonable, do not change the position of existing output shaft on the drilling machine multi-shaft device, do not change the characteristics such as custom of people the drilling machine machining.
The utility model quick-changing type output sleeve, it is characterized in that: it contains a hydraulic quick coupler, the top of this hydraulic quick coupler have one can make its sleeve the slotting axis hole on the output shaft, in addition end have one with the concentric slotting drill bit bore of slotting axis hole, sidewall on have the through hole that can be connected with the pin sleeve with output shaft, the sliding sleeve of band spring and one group are housed between hydraulic quick coupler and the output shaft can in the moving of sliding sleeve, snap in the groove on the output shaft sidewall to realize that hydraulic quick coupler is at the axially quick steel ball of locating of output shaft.
The utility model quick-changing type output sleeve, the slotting axis hole of its hydraulic quick coupler and the mating surface of output shaft are preferably taper seat.To make things convenient for the quick-changing type output sleeve toward the output shaft upper sleeve.
The beneficial effects of the utility model: 1) the quick-changing type output sleeve can be used as the many covers of accessory outfit of drilling machine, and the prior drill bit that need change well of clamping within it, shut down in a flash at the drilling machine bit change then, directly the modulated quick-changing type output sleeve sleeve of finishing changing drill bit is got final product to output shaft; Because the sleeve of this quick-changing type output shaft is more than directly convenient, fast at the output shaft drill bit of removing stage makeup and costume, so can significantly reduce downtime, production efficiency improves thereupon; Thereby solved existing drilling machine multi-shaft device is the disadvantage that bit change must be shut down for a long time; 2) the quick-changing type output sleeve is rational in infrastructure, for example it makes the moment of torsion transmission reliable by being connected with the pin of output shaft, groove, sliding sleeve, steel ball and spring by being provided with on the output shaft again, fast in the axially reliable location of output shaft, therefore in quick and easy sleeve, still guaranteed the cutting precision of drilling machine multi-shaft device; 3) the utility model is after drilling machine multi-shaft device output shaft upper sleeve has been installed the quick-changing type output sleeve, neither change the structure of drilling machine multi-shaft device, also keep the custom of people, but also help applying because of the simple in structure, easily manufactured of quick-changing type output sleeve drilling machine boring.

The specific embodiment
The structure of embodiment 1, present embodiment quick-changing type output sleeve can be seen from Fig. 1～Fig. 3, it contains a hydraulic quick coupler 5, the top of this hydraulic quick coupler have one can make its sleeve the slotting axis hole 5a on the output shaft 1, in addition end have one with the concentric slotting drill bit bore 5b of slotting axis hole 5a, sidewall on have the through hole 5c that can be connected with pin 2 sleeves with output shaft 1 and the embedded hole 5d of steel ball 6; Sliding sleeve 3 and one group of steel ball 6 that is arranged in embedded hole 5d and can axially locatees fast at output shaft with realization hydraulic quick coupler 5 at the groove 1a that moving of sliding sleeve 3 snaps on the output shaft sidewall of being with spring 4 are housed between hydraulic quick coupler 5 and the output shaft 1.
When being inserted into the quick-changing type output sleeve on the output shaft 1, as long as the slotting axis hole 5a by hydraulic quick coupler 5 inserts output shaft 1, at this moment sliding sleeve 3 promotes under the effect of spring 4 among the groove 1a that steel ball 6 enters output shaft, realize the axial location of quick-changing type output sleeve on output shaft 1, will sell 2 through hole 5c and the output shaft pin-and-hole 1b that insert hydraulic quick coupler simultaneously again and get final product.Otherwise, will be when output shaft 1 takes off with the quick-changing type output sleeve, then take out pin 2 earlier and move down sliding sleeve 3 from hydraulic quick coupler and output shaft, steel ball 6 can move back to from the groove of output shaft sidewall in the larger-diameter endoporus of sliding sleeve, and the quick-changing type output sleeve can be thrown off output shaft 1.So easy disassembly of present embodiment quick-changing type output sleeve.
When output shaft need be changed drill bit, can shut down present embodiment quick-changing type output sleeve is taken off from output shaft, the quick-changing type output sleeve sleeve that another group the has been installed drill bit work of can starting shooting again to the output shaft again.The time of whole shutdown only spends in pulling out of quick-changing type output sleeve and unloads and plug-in mounting, rather than is used for the demolition, installation drill bit, so can significantly reduce downtime.
