Abstract

The utility model discloses a rotary coupler. The rotary coupler comprises a core body, a cover plate, a shell body, plain bearings and plane bearings, wherein the core body, the plain bearings and the plane bearings are installed in the shell body, the plain bearings and the plane bearings are distributed on the two sides of the core body respectively, the plane bearings are arranged at the position of connection among the core body, the shell body and the cover plate, the plain bearings are arranged between the core body and the plane bearings, the cover plate is connected with the shell body, the core body is of a cross shape, and a through hole which is used in cooperation with the core body is formed in the cover plate. According to the rotary coupler, an existing common rotary air cylinder or an existing common rotary oil cylinder can be replaced by an ordinary air cylinder with the added rotary coupler, or an ordinary oil cylinder with the added rotary coupler. Compared with the rotary air cylinder or the rotary oil cylinder, the use cost of the rotary coupler is lower, the price of the rotary coupler is only about 20% that of the rotary air cylinder or the rotary oil cylinder, repair and maintenance can be more convenient, and the working stroke can be longer.

Description

Revolution shaft coupling

Technical field

The utility model relates to mechanical transmissioning technology field, specifically a kind of revolution shaft coupling.

Background technology

Rotary cylinder is a kind of cylinder acting on jig and wire coil device, the cylindrical metal parts that guiding piston carries out straight reciprocating motion therein, conventionally be applied on mechanical processing machine, in particular for the part of machine tooling, clamp clamping force is provided, when clamping processing parts, can provide at any time clamping force or unclamp part, operation is very easy.In order to promote the clamping force output of rotary cylinder, the inner dual-piston structure that adopts of some rotary cylinder provides clamping force to export by double-piston simultaneously, increases the power that clamps to machining workpiece, makes to clamp more stable.But because rotary piston cylinder use cost is high, maintenance is inconvenient, and maintenance is inconvenient, and impulse stroke is shorter, affects machine tooling efficiency.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the utility model discloses a kind of revolution shaft coupling.

The technical scheme that the utility model adopts is: revolution shaft coupling, comprise core body, cover plate, housing, plain bearing, plane bearing, core body, plain bearing, plane bearing are installed in described housing, described plain bearing, plane bearing are distributed in core body both sides, described plane bearing is positioned at described core body and housing, cover plate junction, described plain bearing is between described core body and described plane bearing, and described cover plate is connected with housing.

As preferably, described core body is cross.

As preferably, described cover plate is provided with the through hole matching with core body, has good sealing property.

The beneficial effects of the utility model are, the disclosed a kind of revolution shaft coupling of the utility model, can be used in lathe collet clamping and unclamp or the clamping of lathe Special tooling clamp, as long as add upper rotary shaft coupling with common cylinder or oil cylinder, just can substitute present conventional rotary cylinder or angling cylinder.Compare rotary cylinder and angling cylinder, the use cost of revolution shaft coupling is lower, and the price of revolution shaft coupling only has 20% left and right of rotary cylinder and angling cylinder, and maintenance and maintenance are also convenient, and impulse stroke more lengthens.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The specific embodiment

In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.

Specific embodiment of the utility model is, revolution shaft coupling as shown in Figure 1, 2, comprise core body 1, cover plate 2, housing 3, plain bearing 4, plane bearing 5, core body 1, plain bearing 4, plane bearing 5 are installed in housing 3, plain bearing 4, plane bearing 5 are distributed in core body 1 both sides, plane bearing 5 is positioned at core body 1 and housing 3, cover plate 2 junctions, and plain bearing 4 is between core body 1 and plane bearing 5, and cover plate 2 is connected with housing 3.Core body 1 is cross.Cover plate 2 is provided with the through hole matching with core body 1.

Revolution shaft coupling as shown in Figure 3, revolution shaft coupling one side is connected with common cylinder, opposite side is connected with collet, when turning round the two ends motion for the relative rotation of shaft coupling, one end to other end transmitter shaft to thrust and pulling force.

The disclosed a kind of revolution shaft coupling of the utility model, can be used in lathe collet clamping and unclamp or the clamping of lathe Special tooling clamp, as long as add upper rotary shaft coupling with common cylinder or oil cylinder, just can substitute present conventional rotary cylinder or angling cylinder.Compare rotary cylinder and angling cylinder, the use cost of revolution shaft coupling is lower, and the price of revolution shaft coupling only has 20% left and right of rotary cylinder and angling cylinder, and maintenance and maintenance are also convenient, and impulse stroke more lengthens.

Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modifications that are equal to replacement or make according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, within all should being included in the desired interest field of the utility model.
