Abstract
The utility model relates to a mechanical device, in particular to a self-centering floating clamp for clamping workpieces, which has the technical scheme that the self-centering floating clamp comprises a clamp body and a clamp claw arranged on the clamp body, the center part of the clamp body is provided with a tip; and the clamp claw is in slip connection with the clamp body. The utility model is mainly used for machining the parts such as bearings and the like.
Description
Technical field
The utility model relates to mechanical device, particularly a kind of self centering, floating chuck that is used for clamping workpiece.
Background technology
Axial workpiece is a kind of typical part commonly used, is mainly used in to transmit motion and moment of torsion in various plant equipment.Therefore, the Machining of Shaft-type Parts specification requirement is as a rule all than higher.
The Machining of Shaft-type Parts means generally adopt turning and grinding, mainly are turning.But Machining of Shaft-type Parts is the holonomic system that lathe, anchor clamps, cutter and workpiece constitute, and is referred to as process system.
As everyone knows, process system exists more error component, have only all errors in the process system are reduced to minimum, could guarantee the part processing precision height, wherein especially the clamping error ratio of workpiece is more outstanding, because the clamping error comprises position error and two aspects of clamp error, these two errors directly influence the machining accuracy of workpiece.
Present common three-pawl type fixed chuck adopts and clamps the mode of afterwards feeling relieved earlier, is easy to generate the then easier centering error that causes of clamping, greatly reduces the machining accuracy of workpiece.
The utility model content
The purpose of this utility model provides the accurate self centering, floating chuck in a kind of location, and it has the advantages that to feel relieved and afterwards clamp earlier, has abandoned traditional big locate mode of a crown one head-clamp position error.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of self centering, floating chuck, and comprise collet body, be arranged at the jaw of collet body, it is characterized in that: described collet body central part is provided with top; Described jaw and collet body are slidingly connected.Workpiece end face withstand described top after, jaw slides to the collet body central part, thus clamping work pieces is realized the installation way of feeling relieved and afterwards clamping earlier, to guarantee the zero clamping error in the workpiece process.
As preferably, be with two oscillating bearings outside the described top middle part, clamping between two oscillating bearings has spheroid, and spheroid is provided with Spring Card near a top end, and the other end of the relative Spring Card of spheroid is fixedly connected with movable joint, and movable joint is fixedlyed connected with jaw.Two oscillating bearings drive spheroid moving linearly in the gap that is formed by two oscillating bearings, thereby drive movable joint and jaw generation displacement, for guaranteeing not easy damaged workpiece, are provided with Spring Card at spheroid near a top end, to realize Flexible Fixturing.
As preferably, described top tail end is provided with the oil cylinder adapter sleeve that is used to connect oil cylinder.The oil adapter sleeve is used to connect oil cylinder, and oil cylinder drives the oscillating bearing motion.
In sum, the utlity model has following beneficial effect:
1, adopts the big traditional locate mode of a crown one head-clamp position error owing to abandoning, and take to locate the installation way that afterwards clamps earlier, make and realize location " zero " error in the work process.
2, be provided with Spring Card at spheroid near a top end, when making jaw depend on position that workpiece reserved to clamp, be unlikely to picture and adopt the fixedly rigid clamping of three-jaw, the workpiece clamp of having had good positioning is askew, thereby the realization Flexible Fixturing has been created good condition for improving the workpiece machining accuracy.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model side sectional view;
Among the figure, 01, jaw, 02, collet body, 03, adapter sleeve, 07, oscillating bearing, 09, movable joint, 011, spheroid, 012, Spring Card, 015, the oil cylinder adapter sleeve, 019, top, 020, closing disk, 024, top sheath.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
A kind of self centering, floating chuck, as shown in drawings, this self centering, floating chuck is the three-pawl type chuck, comprises jaw 01, collet body 02, oscillating bearing 07, movable joint 09, oil cylinder adapter sleeve 015, top 019.The distribution of jaw 01 as shown in Figure 1, adjacent jaw 01 is 120 degree and divides and to be located at collet body 02 end face.
As shown in Figure 2, collet body 02 is fixedly connected with closing disk 020 by top 019 head place, and top 019 head is arranged with top sheath 024, and top 019 head passes top sheath 024, and top sheath 024 is fixed and fixedlyed connected with closing disk 020.
Top 019 middle part is arranged with two oscillating bearings 07, clamping between two oscillating bearings 07 and the corresponding spheroid 011 of three jaws, 01 difference, spheroid 011 is provided with Spring Card 012 near top 019 1 ends, the other end of spheroid 011 relative Spring Card 012 is fixedly connected with movable joint 09, and movable joint 09 is fixedlyed connected with corresponding jaw 01.
Be provided with oil cylinder in the oil cylinder adapter sleeve 015, after workpiece end face withstands described top 019, oil cylinder drives oscillating bearing 07 motion, make spheroid 011 moving linearly between by two oscillating bearings, 07 formed gap, thereby driving jaw 01 slides to the collet body central part, and then clamping work pieces, realize the installation way that elder generation feels relieved and afterwards clamps, to guarantee the zero clamping error in the workpiece process, for guaranteeing not easy damaged workpiece, be provided with Spring Card 012 at spheroid 011 near top 019 1 ends, to realize Flexible Fixturing.
