Description
Technical field
The invention belongs to metal pipe material processing equipment technical field, be specifically related to a kind of power output shaft of cold pilger mill slew gear and the fit structure of plug chuck.
Background technology
Cold pilger mill widely uses in the tubing processing industry; And in the Chinese patent document, be no lack of the technical scheme that is seen in relevant cold pilger mill, slightly with give an example like the continuous feeder of the disclosed a kind of two cold mill pipes of the novel license notification number of practicality CN201223884Y, the achievement part of this scheme has solved the technical problem that the double-roller cold pilger mill that has earlier can not continuous operation; Because; Double-roller cold pilger mill in the prior art is after sending completion to, owing to send dolly to and can only withstand the pipe rear end, sending dolly to must rollback to home position (resetting); Be housed to next root pipe; The pipe that penetrates plug gets into sends dolly to, begins to send to after sending dolly chucking pipe to, so exist one section to send auxiliary times such as dolly rollback and charging, chucking to; Cause this cold pilger mill can not continuous operation, so this patent scheme can be increased work efficiency undoubtedly.And for example: the revolution feed mechanism of a kind of cold pilger mill that CN2788915Y recommends has the alleged technique effect of Instructions Page 2 the 14th～19 row of this patent.For another example: the cold pilger mill that CN2621094Y introduces send slew gear to; This scheme will be sent between the head and feeding lathe bed that slew gear is arranged at cold pilger mill; Cancelled the jackshaft system and the 2-level reducer of the cold pilger mill in the prior art, the floor space of cold pilger mill is significantly reduced.
Except above-mentioned technical scheme of giving an example; Also just like CN2385817Y (feed mechanism of cold pilger mill), CN2386900Y (pipe mill send to slew gear), CN2656036Y (cold pilger mill is sent slew gear to), CN201067762Y (electrical control is sent to and rotating novel pipe mill), CN201470679U (the steel pipe rotation feed mechanism of pipe mill), CN201543661U (a kind of revolution feed mechanism of double-roller cold pilger mill) and CN201592194U (hydraulic revolving feed device of cold pilger mill), or the like.
Aforesaidly send the comprehensive appellation that slew gear is feed mechanism and slew gear to; These two key mechanism that mechanism is a cold pilger mill; The effect of slew gear is plug revolution used when making tube rolling; And the effect of feed mechanism is to drive dolly, by the rear end pushing tow of dolly with pipe, supplies the roll of tube rolling mechanism rolling.Aforesaid plug is that string is inserted in the through hole of power output shaft, that is to say.Power output shaft has the output shaft through hole that is through to the other end from an end; Plug is located in the output shaft through hole; And the claw by setting on the chuck blocks plug; Chuck is located at the axle head of power output shaft, and the part of the thickness direction of chuck leans out the axle head end face of power output shaft, so that make one group of claw on the chuck to clamping by way of the plug of output shaft through hole or discharging.
In said structure; Because claw is clamped outside the end face that the position is in power output shaft plug; Therefore the part of the thickness direction of chuck shows as cantilever position on power output shaft, so in the process of chuck with the power output shaft rotation, exist chuck to throw away the anxiety of power output shaft.In addition, make claw on the chuck to the operation of the folding up of plug (clamp or discharge) by manual realization, so operator's working strength is big and inefficient operation, influences the rolling efficiency of cold pilger mill to steel pipe.
Summary of the invention
Task of the present invention is to provide a kind of can guarantee that chuck is positioned at all the time on the power output shaft and can occur being free on power output shaft and need not to use through the manual operation chuck power output shaft and the fit structure of plug chuck of the cold pilger mill slew gear of the operating efficiency that alleviates operator's working strength and improve chuck.
Task of the present invention is accomplished like this; The fit structure of a kind of power output shaft of cold pilger mill slew gear and plug chuck; Comprise the power output shaft body and be located at the plug chuck body on the power output shaft body; The end that the power output shaft body has a ultromotivity output shaft body is through to the output shaft through hole of the other end; Be characterised in that: the circumferencial direction that centers on the power output shaft body at an end of described power output shaft body and at the position corresponding to said plug chuck body is equidistantly spaced and is provided with one group of claw groove, and each claw groove communicates with said output shaft through hole; Be equidistantly spaced equally on the described plug chuck body and around the circumferencial direction of plug chuck body and be provided with the corresponding claw sliding tray in position that one group of quantity equates with the quantity of said claw groove; And the corresponding both sides on the top of each claw sliding tray respectively are concaved with a claw guide plate groove; Slide in each claw sliding tray and be equipped with a claw; The top of each claw is installed with a claw guide plate; Claw guide plate and described claw guide plate groove are slidingly matched, and claw is corresponding to described claw groove; On the outer wall of described plug chuck body and offer a ring-type and slider slideway that connect around the circumferencial direction of plug chuck body, in this slider slideway, sliding, it is a pair of each other with the slide block that is connected with the chuck actuating device of being used at 180 ° of intervals to be equipped with.
In a concrete embodiment of the present invention; Be concaved with a collar groove in the end of described power output shaft and at position corresponding to the right side of said plug chuck body; In the collar groove, be embedded with a collar; And this collar is furnished with a centring ring and positioning sleeve, and centring ring and positioning sleeve all are nested with on the power output shaft body, wherein: centring ring is positioned at the side towards said plug chuck body of collar; And positioning sleeve and be positioned at the opposite side of collar, and centring ring and positioning sleeve are fixed to one another and collar is limited between centring ring and the positioning sleeve.
Technical scheme provided by the invention is because at an end of power output shaft body and offering one group of claw groove corresponding to the position of plug chuck body; Therefore the plug chuck body need not to resemble and under the state of the end face that leans out the power output shaft body, plug is clamped the prior art or discharged, the plug chuck body situation in the power output shaft body that can not occur escaping; Owing on the plug chuck body, offered slider slideway; And in slider slideway, be provided with a pair of slide block; Therefore, as long as a pair of slide block is connected with the chuck actuating device, just can make the plug chuck body at power output shaft body top offset through slide block by the chuck actuating device; Make claw in the claw sliding tray that is located at the plug chuck body to being in plug in the output shaft through hole and clamping or discharging; Need not to resemble the prior art by manual the operation of plug chuck body, not only can alleviate operator's working strength, and can raise the efficiency.
