Abstract
The utility model relates to a clamping device special for milling a needle frame arc surface, which comprises a pedestal, a fixed chassis, a rotary chassis, a positioning pin, a positioning platform and a pressing plate, wherein the fixed chassis is fixedly arranged on the upper surface of the pedestal horizontally; the rotary chassis is rotationally mounted on the upper surface of the fixed chassis; a regulating handle is mounted on the rotary chassis; the positioning pin is fixedly arranged in the center of the upper surface of the rotary chassis; the positioning platform is fixedly arranged on the upper surface of the rotary chassis; and the pressing plate is mounted on the upper surface of the rotary chassis through a set screw. The rotary chassis serves as the positioning reference pedestal, a needle frame can be clamped on the upper surface of the rotary chassis stably and precisely, and rotation of a workpiece in milling processing can be realized by manually adjusting the rotary chassis, so that milling processing of the work arch surface is realized. Bearing transmission is adopted, so friction is reduced, the roughness of the processing surface is improved, and the clamping device has the advantages of convenience, quickness and stability in clamping, high processing precision and high processing efficiency.
Description
Technical field
The utility model belongs to industrial sewing machine accessory processing unit (plant), particularly a kind of milling punch block arc surface clamping device special.
Background technology
Punch block is requisite parts in the industrial sewing machine, is used for the insert syringe needle.The main body of punch block is circular arc, therefore need to carry out milling to the arc surface of punch block.Retainer when assembling dimensional accuracy and roughness require very strict, adopt machine tool, need to finish relatively moving of milling cutter and bed in process, regulate very complicatedly, and working (machining) efficiency is low, and is difficult to guarantee its specification requirement in the processing, and the workpiece yield rate is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of clamping reliable and stable, and workpiece is rotatable, thus but the milling punch block arc surface clamping device special of Effective Raise machining accuracy and working (machining) efficiency.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of milling punch block arc surface clamping device special, it is characterized in that: consisted of by base, fixed underpan, swivel base, alignment pin, positioning table and pressing plate, be fixedly mounted with fixed underpan in the base upper surface level, rotate the installation swivel base at this fixed underpan upper surface, on this swivel base regulating handle is installed, upper surface center at this swivel base is fixed with alignment pin, also be fixed with positioning table at the swivel base upper surface, also by screw pressing plate be installed at the swivel base upper surface.
And described swivel base is rotatably installed on the described fixed underpan by bearing.
Advantage of the present utility model and good effect are:
The utility model scientific structure design is reasonable, adopt swivel base as the positioning datum base, by pressing plate and positioning table, punch block can be stablized accurate clamping and turn the chassis upper surface, by the manual adjustments swivel base, can realize the rotation of workpiece in the Milling Process, thereby realize the Milling Process of workpiece circular arc face; Simultaneously, use bearing-transmission, can reduce friction, improve the roughness of machined surface, have a clamping convenient stable, machining accuracy is high, the advantage that working (machining) efficiency is high.
Description of drawings
Fig. 1 is front view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of milling punch block arc surface clamping device special, it is made of base 8, fixed underpan 1, swivel base 2, alignment pin 4, positioning table 3 and pressing plate 5, be fixedly mounted with fixed underpan in the base upper surface level, rotate the installation swivel base at this fixed underpan upper surface, swivel base is rotatably installed on the described fixed underpan by bearing 6.Regulating handle 7 is installed on this swivel base, is fixed with alignment pin in the upper surface center of this swivel base, also be fixed with positioning table at the swivel base upper surface, also by screw pressing plate is installed at the swivel base upper surface.
Operation principle of the present utility model is:
Adopt swivel base as the positioning datum base, by pressing plate and positioning table, punch block can be stablized accurate clamping turning the chassis upper surface, by the manual adjustments swivel base, can realize the rotation of workpiece in the Milling Process, thereby realize the Milling Process of workpiece circular arc face; Simultaneously, use bearing-transmission, can reduce friction, improve the roughness of machined surface.
After the utility model workpiece is installed, can realize 360 degree rotations of product, flexible operation, can guarantee after the processing that the punch block arc diameter margin of tolerance is in 0.02mm, through measuring, roughness can be controlled in the Rz1.5s, has solved the technical barrier of machine tool machining high-precision circular arc.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
