Description

Tooling for machining bracket

Technical Field

The utility model relates to the field of bracket machining, in particular to a tool for machining a bracket.

Background

The front and back brackets of the Ka-T-R base are brackets processed by clients in our factory, the front and back brackets of the Ka-T-R base are forged thin plate pieces, the appearance of a workpiece is greatly influenced by forging temperature, the appearance tolerance is required to be controlled to be plus or minus 0.6 mm, and in the machining process, the coaxiality of the small end connecting holes of the brackets and the bosses is required to be 0.25 mm when the small end connecting holes of the brackets are processed, so that classified screening processing is required, the forge piece is a special-shaped piece, the bolt pressing plate is required to be pressed on a flange plate for turning, the clamping is complex, and the workpiece sorting is time-consuming, so that the production efficiency is influenced.

Therefore, a tooling for machining the bracket needs to be designed.

Disclosure of Invention

Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description. The embodiments of the utility model have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.

1-4, including roof 1, bottom plate 2 and lever board 3, the center of bottom plate 2 is concave downwards, forms work piece space 23, and the center of bottom plate 2 is provided with centre bore 22, and the center of roof 1 is provided with lever board chamber 12, lever board 3 movable mounting in lever board chamber 12, is provided with spring 31 between the afterbody of lever board 3 and roof 1, and spring 31 has holding power to lever board 3, makes lever board 3 extrude the work piece.

The top plate 1 is provided with a plurality of first holes 11, the bottom plate 2 is provided with a plurality of second holes 21, when the bottom plate 2 is attached to the bottom of the top plate 1, the first holes 11 are aligned with the second holes 21, and then the bottom plate is mounted by bolts.

The bottom surface portion of the lever plate 3 is located in the work space 23, and can press the work placed in the work space 23.

After the components are assembled, the top plate 1 is fixed on a hydraulic chuck, then the lever plate 3 is used for applying pressure to the workpiece, the workpiece is tightly propped against the bottom plate 2, and a machining center is used for milling and positioning a cavity on the bottom surface of the square box, so that the problem of inaccurate positioning is solved; finally, a mandrel on the hydraulic piston shaft drags the lever plate to move back and forth, so that the workpiece clamping function is realized, and finally, the function of automatically clamping the workpiece by hydraulic pressure is achieved.

It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art and which are included in the embodiments of the present utility model without the inventive step, are intended to be within the scope of the present utility model. Structures, devices and methods of operation not specifically described and illustrated herein, unless otherwise indicated and limited, are implemented according to conventional means in the art.
