Abstract
The utility model provides a mechanical expanding shaft in a side manipulation mode, which comprises a coiled material sleeve, an expanding block, an expanding core, an expanding shaft pull rod, an expanding shaft with an expanding core, a driving bevel gear and a driven bevel gear, wherein the pair of bevel gears are engaged, and the driving bevel gear is arranged on the expanding shaft with an expanding core; a spanner hole is arranged at one end of the driving bevel gear towards the outside, and a spanner jack is arranged in the outer wall of the expanding shaft corresponding to the spanner hole; an internal thread is arranged at the core part of the driven bevel gear, an external thread is arranged at the top of the expanding shaft pull rod, and the driven bevel gear is mounted at the top of the expanding shaft pull rod. The utility model adopts a pair of bevel gears to tighten the expanding shaft pull rod so as to realize the expanding strain of the sleeve, namely utilize the transmission of the orthogonal bevel gears to realize side manipulation, and the utility model has the characteristics of smart structure design and convenient operation.
Description
Technical field
The machinery that the utility model relates to a kind of coiled material cutting apparatus batches bloated axle construction, specifically, has related to the bloated axle of a kind of side control type machinery.
Background technology
In the prior art, the machinery that is used for the coiled material cutting apparatus batches the axle that expands and mainly contains two kinds of structures: first kind is the bloated axle that does not have the breathing function, the precision of beating of coiled material guarantees with coiled material sleeve quality of fit that by the axle that expands the rotation of coiled material realizes with expanding axle two end nut clamp sleeves fully; Second kind is the bloated axle of the bloated core of band, though overcome the shortcoming of above-mentioned bloated axle, the operation that screws of the core that expands is at the axle two ends of expanding, promptly in the inside of expanding the axle mounting face, this bloated axle is before being installed on the machine, must be on axle with the coiled material swelling, and after definite swelling is errorless, could lift on the machine, in a single day loose winding takes place in the middle of work, must repeat above-mentioned work, obviously, there is the very shortcoming of inconvenience of operation in it.
In order to solve the problem of above existence, people are seeking a kind of practical technical scheme that is suitable for always.
The utility model content
Goal of the invention of the present utility model is at the deficiencies in the prior art, thereby provides a kind of structure design ingenious, the easy to operate bloated axle of side control type machinery.
In order to realize the foregoing invention purpose, the utility model provides a kind of side control type machinery bloated axle, comprise the coiled material sleeve, piece expands, core expands, the bloated axle of the bloated core of bloated axle pull bar and band, this machinery expands that axle also comprises one group of ingear drive bevel gear and by dynamic bevel gear, described drive bevel gear is arranged on the bloated axle of the bloated core of band, the outside end of described drive bevel gear core is provided with spanner hole, the outer wall of described bloated axle is provided with the spanner jack, the corresponding described spanner hole setting of described spanner jack, described core by dynamic bevel gear is provided with negative thread, the top of described bloated axle pull bar is provided with outside thread, the described top that is installed in described bloated axle pull bar by dynamic bevel gear.
The relative prior art of the utility model has substantive distinguishing features and progressive, specifically, this side control type machinery expands axle employing bevel-gear sett to strain the axle pull bar that expands, and then the tensioner of realization sleeve, promptly utilize the bevel gear with axes at right angles transmission, the realization side is handled, and it has ingenious, the convenience operation of structure design.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
As shown in Figure 1, mechanical bloated of a kind of side control type comprises coiled material sleeve 6, bloated piece 5, bloated core 4, a bloated pull bar 7 and is with bloated core bloated 1;
Described bloated axle also comprises one group of ingear drive bevel gear 2 and by dynamic bevel gear 3, described drive bevel gear 2 is arranged on the bloated axle 1 of the bloated core of band, the outside end of described drive bevel gear 2 cores is provided with spanner hole, the outer wall of described bloated axle is provided with the spanner jack, the corresponding described spanner hole setting of described spanner jack;
Described core by dynamic bevel gear 3 is processed with negative thread, and the top of described bloated axle pull bar 7 is processed with outside thread, by described negative thread and described externally threaded the cooperation, makes the described top that is installed in described bloated axle pull bar 7 by dynamic bevel gear 3.
The utility model adopts bevel-gear sett, screws direction by change, and the axle pull bar 7 that expands is progressively strained, thereby reaches the purpose of tensioner coiled material sleeve 6.
When utilizing spanner or other instrument to rotate described drive bevel gear 2, then described drive bevel gear 2 drives have the described of negative thread is rotated by dynamic bevel gear 3, and then the axle pull bar 7 that expands is progressively strained, thus tensioner coiled material sleeve 6, on the contrary then unclamp.
Promptly utilize bevel gear with axes at right angles break-in transmission, realized that the side of mechanical bloated axle is handled, have distinguishing feature simple to operate.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
