Abstract

The utility model relates to a driving apparatus for a mechanical driving tension machine, which comprises a power converter, an output shaft, a shaft coupling, an outer wheel of a clutch, a turn key, a turn key keyboard, a tail cover, a camshaft and a bearing seat. The utility model is characterized in that the shaft coupling on the power output shaft is directly connected with the outer wheel of a clutch, and the camshaft is driven to rotate through the transference of the outer wheel of a clutch and the turn key. A double-pole or multi-pole tension machine can also be made of output shafts in the multiple directions of the power converter. The utility model with the structure has the advantages of part saving, size and weight reduction and ingenuity and practicality of equipment.

Description

A kind of transmission device of tensile machine

The utility model relates to the transmission device of a kind of mechanical structure device, particularly a kind of tensile machine.

Tensile machine is a kind of machine tool of punch process, the tensile machine of existing machinery transmission, normally the power of motor passes to retarder by belt, give sprocket wheel or gear on the engaging and disengaging gear foreign steamer by the sprocket wheel on the reducer output shaft or gear transmission again, pass to the rotatingshaft of cam through the joint of turn key, make shaking and to-and-fro motion of cam rotation drivening rod, cause the pull bar to-and-fro motion, finish the purpose of machinery pulling.This drive mechanism, because need use sprocket wheel or gear transmission on the foreign steamer of the output shaft of retarder and engaging and disengaging gear, cost of parts increased; And the axis of the output shaft of retarder and the foreign steamer of engaging and disengaging gear has increased the volume and weight of equipment not on same axis.So, be not the structure of a kind of saving, compactness, exquisiteness.

The purpose of this utility model is to provide a kind of sprocket wheel between pto and the engaging and disengaging gear or gear transmission and compact structure, lower-cost tensile machine of saving.

Task of the present utility model is achieved in that

The transmission device of tensile machine comprises power converter (1), output shaft (2), coupling (3), clutch foreign steamer (4), turn key (10), turn key keyboard (7), tail-hood (8), camshaft (6), bearing support (5), it is characterized in that on the pto coupling directly and the clutch foreign steamer link, by the transmission of clutch foreign steamer, turn key, drive camshaft and rotate.This transmission device also can utilize the output shaft of a plurality of directions of power converter, mix corresponding engaging and disengaging gear and driving component after, that makes two bars and many bars can be synchronous or the tensile machine of asynchronous operation.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the plan view of the utility model single pole structure.

Fig. 2 is the side view of the utility model single pole structure.

Fig. 3 is the plan view for the two asynchronous operating structures of bar of the utility model.

The output shaft (2) of power converter (1) is gone up coupling (3) is installed, this coupling can be the clip wheel formula, the dental forceps formula, the first-class form of concavo-convex shell type or cross, coupling (3) in a variety of forms with clutch on foreign steamer (4) link, foreign steamer on the clutch (4) is by bearing support (5) supporting (also this bearing support can be installed in the next door of cam (12)), camshaft (6) is being supported by keyboard (7) and tail-hood (8) and small bearing bracket (9), foreign steamer is separable or engage moment of torsion is passed to camshaft (6) by turn key (10), connecting rod (11) is enclosed within on the cam (12) with the slip form, its far-end links to each other with pull bar (14) by a strand (13), (15) be to lean against retarder in the other direction, utilize its two output shaft (16) and (17) and above-mentioned principle to can be made into the tensile machine (18) that pair bars can asynchronous operation.

Claims

1, a kind of transmission device of tensile machine, comprise power converter, output shaft, coupling, clutch foreign steamer, turn key, turn key keyboard, tail-hood, camshaft, bearing support, it is characterized in that on the pto coupling directly and the clutch foreign steamer link, by the transmission of clutch foreign steamer, turn key, drive camshaft and rotate.

2, transmission device according to claim 1 is characterized in that coupling can be forms such as clip wheel formula, dental forceps formula, concavo-convex shell type or cross hair style.

3, transmission device according to claim 1 is characterized in that selecting for use the pto of a plurality of directions, mixes corresponding clutch, and that makes two bars and many bars can be synchronous or the tensile machine of asynchronous operation.
