Work piece automatic centering and clamping mechanism is including the anchor clamps body, die clamping cylinder, push pedal, bearing, press from both sides specific side setting die clamping cylinder, link firmly the push pedal on die clamping cylinder's the piston rod push pedal upper portion sets up the bearing, the inner circle of bearing link firmly in in the push pedal, the quantity of bearing is two, be provided with backer's face on the anchor clamps body. The utility model is suitable for a self -holding of work piece is realized to the machine -building in -process to the position of correcting the work piece automatically, it is reliable and stable to the clamping -force of work piece, improve production efficiency.

Description

Workpiece self-centering and clamping mechanism

Technical field

The utility model relates to industry producing apparatus, more specifically, it relates to a kind of frock clamp equipment for fixation workpiece position.

Background technology

Fixture adds to be used for rapid fastening workpiece man-hour, makes lathe, cutter, workpiece keep the process unit of correct relative position. That is frock clamp is the parts that mechanical workout is indispensable, at machine tool technology at a high speed, under the drive that develops of efficient, precision, compound, intelligence, environmental protection direction, clamp technology just develops towards high-precision, efficient, module, combination, direction general, economic.

Fixture is also known as jig. From inventionbroadly, any operation in technological process, is used for rapidly, installs easily and safely the device of workpiece, all can be called fixture. Such as welding settings, inspection jig, assembling jig, lathe fixture etc. Wherein lathe fixture is the most common, often referred to as fixture.

On lathe during processing work, the dimensions that reaches drawing for making the surface energy of workpiece and specify, geometrical shape and with the technical requirements such as the relative-position error on other surfaces, workpiece must be filled before processing (location), folder jail (clamping).

Application lathe fixture, is conducive to ensureing working accuracy, the stabilized product quality of workpiece; Be conducive to improving labour productivity and reducing costs; Be conducive to improving workman's labor condition, ensure safety in production; Be conducive to expanding lathe processing range, it is achieved " machine is multiplex ".

Practical novel content

The purpose of this utility model there are provided a kind of workpiece self-centering and clamping mechanism, the utility model is applicable in machinofacture process, it is achieved the automatic clamping of workpiece, and automatically corrects the position of workpiece, the holding force of workpiece is reliable and stable, it is to increase production efficiency.

A kind of workpiece self-centering and clamping mechanism, comprise clamp body, clamping cylinder, push pedal, bearing; Side at described clamp body arranges described clamping cylinder, and the piston rod of described clamping cylinder is connected institute's push pedal, arranges described bearing on described push pedal top, and the inner ring of described bearing is fixed in described push pedal, and the quantity of described bearing is two; Described clamp body is provided with backer face.

Of the present utility model provide a kind of workpiece self-centering and clamping mechanism, compare the useful effect that the utility model has with conventional art as follows:

Side at described clamp body arranges described clamping cylinder, and the piston rod of described clamping cylinder is connected institute's push pedal, and the piston rod of described clamping cylinder can promote described push pedal campaign.Arranging described bearing on described push pedal top, the inner ring of described bearing is fixed in described push pedal, and the quantity of described bearing is two. After workpiece is positioned on described clamp body, the piston rod of described clamping cylinder stretches out, described push pedal is driven to move to the direction of described workpiece, when after described bearing touch to described workpiece, described bearing and described backer realize clamping in the face of described workpiece on three points, the position of described workpiece corrected automatically by described bearing simultaneously, makes described workpiece be positioned at the position determined.

Accompanying drawing explanation

Fig. 1 is the utility model workpiece self-centering and the structural representation of clamping mechanism.

39 clamp bodies, 40 clamping cylinder, 41 push pedals, 42 bearings, 43 backer faces.

Embodiment

Being described in further detail by the utility model below in conjunction with accompanying drawing, but do not form any restriction of the present utility model, element numbers similar in accompanying drawing represents similar element. As mentioned above, it is necessary, the utility model provides a kind of workpiece self-centering and clamping mechanism, for realizing the automatic clamping to workpiece, and automatically correct the position of workpiece, make workpiece be fixed on the position determined.

A kind of workpiece self-centering and clamping mechanism, comprise clamp body 39, clamping cylinder 40, push pedal 41, bearing 42; Side at described clamp body arranges described clamping cylinder 40, be connected on the piston rod of described clamping cylinder 40 institute's push pedal 41, arranging described bearing 41 on described push pedal 41 top, the inner ring of described bearing 41 is fixed in described push pedal 41, and the quantity of described bearing 41 is two; Described clamp body 39 is provided with backer face 43.

Below in conjunction with Fig. 1, further describe principle of work of the present utility model and working process:

Side at described clamp body arranges described clamping cylinder 40, and the piston rod of described clamping cylinder 40 is connected institute's push pedal 41, and the piston rod of described clamping cylinder 40 can promote described push pedal 41 to move. Arranging described bearing 41 on described push pedal 41 top, the inner ring of described bearing 41 is fixed in described push pedal 41, and the quantity of described bearing 41 is two. After workpiece 38 is positioned on described clamp body 39, the piston rod of described clamping cylinder 40 stretches out, described push pedal 41 is driven to move to the direction of described workpiece 38, after described bearing 41 touches described workpiece 38, described workpiece 38 is realized clamping by described bearing 41 and described backer face 43 on three points, the position of described workpiece 38 corrected automatically by described bearing 41 simultaneously, makes described workpiece 38 be positioned at the position determined.

Finally, it should be noted that above embodiment is only the more representational example of the utility model. Obviously, the utility model is not limited to above-described embodiment, it is also possible to have many distortion. Every any simple modification, equivalent variations and modification above embodiment done according to technical spirit of the present utility model, all should think and belong to protection domain of the present utility model.
