Description

Be convenient to the three posts centering frame of workpiece loading and unloading
Technical field
The utility model relates to a kind of device for machine tooling centering, specifically is a kind of three posts centering frame of being convenient to workpiece loading and unloading.
Background technology
The processing of axial workpiece is a kind of common processing mode of mechanical field, because axial workpiece in most cases is used for transmission, need be rotatably assorted with fixed part, therefore the axiality of axial workpiece, surface smoothness etc. is generally had relatively high expectations.In the prior art, add man-hour for major axis, owing to axial length is difficult for centering, for the axiality that guarantees axle all needs to use the centering frame.
The overall structure that present centering frame body adopts mostly, namely adopt the annulus body frame structure of an integral body, by centring means axle class workpiece is fixed on circular ring structure inside, reach the centering effect, such structure centering is effective, but, put into or take out centering very inconvenience during frame will growing class axle spare, extract out from centering frame medial surface otherwise will grow class axle spare exactly, otherwise be exactly the frame taking-up of will feel relieved of mobile centering frame, so not only waste time and energy, and efficient is low, is unfavorable for producing in enormous quantities, for this reason, we need design a kind of centering frame of being convenient to load and unload workpiece, are used for solving the frame workpiece loading and unloading inconvenience of nowadays feeling relieved, inefficient problem.
The utility model content
Problem to be solved in the utility model provides a kind of three posts centering frame of being convenient to workpiece loading and unloading, is used for solving centering frame workpiece loading and unloading inconvenience in the past, inefficient problem.
The technical scheme that the utility model provides is: the three posts centering frame of being convenient to workpiece loading and unloading, comprise and putting on the shelf and undercarriage, described putting on the shelf is connected by rotational pin with undercarriage one end, one end clamps by movable bolt, the outer face is provided with the centering post in the middle part of putting on the shelf, centering post inside has screwed hole, adjusting screw(rod) is put on the shelf by centering post internal thread hole and running through, the undercarriage outer face is provided with two centering posts equally and runs through the adjusting screw(rod) of undercarriage, the middle part outer face of undercarriage between two centering posts also is provided with connecting plate, and affiliated connecting plate lower end is connected and fixed plate.
Described putting on the shelf is connected an end with rotational pin and is provided with the convex piece, and undercarriage is provided with corresponding groove with it, and convex piece and groove mate fully and flexibly connect by rotational pin.Put on the shelf and undercarriage is formed a rotational structure by the cooperation of convex piece and groove and by rotational pin, put on the shelf can be in the undercarriage inner groovy be that turning cylinder rotates with the rotational pin.
The described end lateral surface that is connected with movable bolt of putting on the shelf is provided with the fixed block of open arc connected in star, the undercarriage position of correspondence with it is provided with two contiguous blocks, bearing pin passes contiguous block movable bolt is connected, constituting movable bolt is the rotational structure that axle is rotated with the bearing pin, and fastening nut will be put on the shelf and the undercarriage clamping after movable bolt forwards fixed block arc groove to.
Described centering post is 120 ° each other and evenly distributes.Adjusting screw(rod) in the centering post is used for inner workpiece is felt relieved, and it evenly distributes and makes adjusting screw(rod) can be intersected in a bit, reaches the effect of accurate centering.
Four edges of described fixed head also have four installing holes.Location and installation when installing hole is used for three posts centering frame is installed and fixing.
Described adjusting screw(rod) is positioned at the port top of putting on the shelf with undercarriage and adopts spherical structure.Adjusting screw(rod) is positioned to put on the shelf and will directly contacts with workpiece with the port top of undercarriage, if it is sharp or the larger area structure, not only easily workpiece is damaged, and also is easy to occur the phenomenon of workpiece mal-operation and resonance, is unfavorable for processing; Spherical structure is any surface finish but also very little with the workpiece contact area not only, damages very little to workpiece.
Advantage of the present utility model is: this three posts centering frame of being convenient to workpiece loading and unloading of the utility model design, the loading and unloading workpiece is very convenient, the efficient height.
