Abstract
The utility model relates to the technical field of machining, in particular to a workpiece centering and clamping mechanism, which comprises a copper sleeve, a front flange, a cylinder barrel, a nut, a piston, a rear flange, a flange, a spring, a piston rod, a pressing head and a clamp body, wherein the cylinder barrel is arranged in the clamp body, the piston is fixed on the piston rod through the nut and slides in the cylinder barrel, the copper sleeve is fixed in the front flange, the front flange and the rear flange are respectively arranged at the front end and the rear end of the cylinder barrel, the pressing head is in floating connection with the front end of the piston rod, and the spring is arranged between the front flange and the pressing head. According to the utility model, a workpiece is clamped and centered synchronously, and a clamping process is equivalent to a centering process, so that the production efficiency of equipment and the machining precision of a workpiece are increased, and the stability of equipment is enhanced.
Description
Technical field
What the present invention relates to is the Machining Technology field, is specially a kind of workpiece centering clamp mechanism.
Background technology
Mechanical processing industry in process of production, many workpiece need to clamp in advance earlier the position of back centering workpiece, unclamp workpiece centering mode again behind the manual pretension of present a kind of employings, this kind mode inefficiency, machining accuracy is difficult for assurance, poor stability; The another kind of mode of centering by force that adopts behind the oil cylinder clamping work pieces causes workpiece deformation easily, does not reach required precision.
Summary of the invention
The present invention provides a kind of workpiece centering clamp mechanism, has overcome the deficiency of existing workpiece centering hold-down mechanism.
Technical solution of the present invention is: a kind of workpiece centering clamp mechanism, comprise copper sheathing, forward flange, cylinder barrel, nut, piston, rear flange, flange, spring, piston rod, pressure head, clamp body, and cylinder barrel is installed in the clamp body; Piston is fixed on the piston rod with nut; In cylinder barrel, slide, copper sheathing is fixed in the forward flange, and forward flange and rear flange are installed in the front end and the rear end of cylinder barrel respectively; Pressure head floats and is connected in the front end of piston rod, between forward flange and pressure head, spring is housed.
Beneficial effect of the present invention is: workpiece is clamped with centering carry out synchronously, the process of clamping is exactly the process of centering, has improved the machining accuracy of efficiency of equipment and workpiece, improves the stability of equipment simultaneously.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; A kind of workpiece centering clamp mechanism; Comprise copper sheathing (1), forward flange (2), cylinder barrel (3), nut (4), piston (5), rear flange (6), flange (7), spring (8), piston rod (9), pressure head (10), clamp body (11); Cylinder barrel (3) is installed in the clamp body (11), and piston (5) is fixed on the piston rod (8) with nut (4), in cylinder barrel (3), slides; Copper sheathing (1) is fixed in the forward flange (2); Forward flange (2) and rear flange (6) are installed in the front end and the rear end of cylinder barrel (3) respectively, and pressure head (10) floats and is connected in the front end of piston rod (8), between forward flange (2) and pressure head (10), spring (9) is housed.
Concrete operation principle: during the oil cylinder oil-feed; ((5) travel forward with piston rod (8), are connected in the front end of piston rod (8) because pressure head (10) floats, and between forward flange (2) and pressure head (10), spring (9) are housed to promote piston; Under the elastic force effect of spring (9); Pressure head (10) can adapt to the surface of the work shape along with the variation of thrust automatically in the process of workpiece pressing, to realize centering, until workpiece pressing.
