Abstract
The invention belongs to the technical field of workpiece clamps and particularly relates to a self-centering clamp. The self-centering clamp comprises two cylinders, clamp plates, two racks, clamp bodies, gears, two guide rods, a connecting shaft and a base, wherein the clamp bodies are fixedly arranged on the base, the connecting shaft is transversally arranged in the middles of the clamp bodies, the gears are respectively connected to the two ends of the connecting shaft, the racks matched with the gears are respectively arranged on the gears and respectively connected with the clamp plates, the clamp plates are respectively connected with the cylinders, the cylinders are symmetrically distributed and connected by the guide rods, and the guide rods are longitudinally arranged on the two sides of the connecting shaft symmetrically. The self-centering clamp provided by the invention has the advantages that through the symmetric arrangement of the cylinders, stress is uniform, motion is flexible, locating and clamping are simultaneously realized, and locating accuracy can still be ensured when the multiple clamps are simultaneously used; and through the utilization of a gear and rack transmission structure, the cylinders and the clamp plates can move at the same speed and in opposite directions, and inconsistent motion caused by non-uniform gas supply, gas compressibility and the like is avoided.
Description
Technical field
The invention belongs to the work piece holder technical field, be specifically related to a kind of self-centering fixture.
Background technology
The members such as the column in external wooden house, crossbeam, cant beam are solid wood, and the forming surface such as porose, the translot of distributing on these members, vertical slot, skewed slot are inserted metal connecting piece in forming surface, primary structural component can be cross-linked together, form the main frame in house.Forming surface dimensional accuracy, position accuracy demand are higher, and these forming surface are finished through machining.Because sectional dimension of members is different, size, the position distribution of main machined surface are different, workpiece needs repeatedly the conversion station, processes through the much knives tool, necessary self-centering during the processing request Workpiece clamping, when the Workpiece length size larger, when needing several anchor clamps to clamp simultaneously, can guarantee the workpiece positioning accuracy.
Summary of the invention
The object of the present invention is to provide a kind of can self-centering anchor clamps.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of self-centering fixture, comprise cylinder, clamping plate, tooth bar, clamp body, gear, guide post, connecting shaft, base, described clamp body is fixed on the base, described clamp body intermediate lateral is provided with connecting shaft, the connecting shaft two ends are connected with respectively gear, be respectively equipped with tooth bar with matching on the gear, two tooth bars are connected with respectively clamping plate, clamping plate links to each other with cylinder respectively, two cylinders are symmetric, and link to each other by two guide posts between two cylinders, and two guide post symmetries vertically are respectively in the connecting shaft both sides.
Further, the number of teeth of described two gears is identical.
Further, described two gears are centrosymmetric, and two tooth bars are centrosymmetric.
The present invention has following beneficial effect: symmetrical 2 cylinders, and stressed even, flexible movements realize positioning and clamping simultaneously, when a plurality of anchor clamps use simultaneously, still can guarantee positioning accuracy; Utilize gear, rack-driving structure to make cylinder, identical, the opposite direction of clamping plate movement velocity size, the motion that avoided that air feed is inhomogeneous, gas compressibility etc. causes is inconsistent.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Among the figure, 1, cylinder, 2, clamping plate, 3, tooth bar, 4, clamp body, 5, gear, 6, guide post, 7, connecting shaft, 8, base.
The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing
Such as Fig. 1, shown in Figure 2, a kind of self-centering fixture, comprise cylinder 1, clamping plate 2, tooth bar 3, clamp body 4, gear 5, guide post 6, connecting shaft 7, base 8, described clamp body 4 is fixed on the base 8, described clamp body 4 intermediate lateral are provided with connecting shaft 7, connecting shaft 7 two ends are connected with respectively gear 5, be respectively equipped with tooth bar 3 with matching on the gear 5, two tooth bars 3 are connected with respectively clamping plate 2, clamping plate 2 links to each other with cylinder 1 respectively, two cylinders 1 are symmetric, link to each other by two guide posts 6 between two cylinders 1, two guide posts, 6 symmetries vertically are respectively in connecting shaft 7 both sides, and the number of teeth of described two gears 5 is identical, described two gears 5 are centrosymmetric, and two tooth bars 3 are centrosymmetric.
Workpiece is placed between two clamping plates 2, two cylinder 1 symmetrical installations promote respectively a clamping plate 2, left side cylinder 1 promotes left side clamping plate 2, the tooth bar 3 that links to each other with this plate promotes gear 5 rotations, another identical gear 5 rotating Vortexes of the number of teeth on the connecting shaft promote tooth bar 3 action, i.e. two identical, the opposite directions of clamping plate movement velocity size that link to each other with right side clamping plate 2, close look at the swing realizes that self-centering clamps.If there is mechanical mechanism to coordinate 1 action of two cylinders, when source of the gas during simultaneously to two cylinder 1 air feed, because that gas distributes is irregular, and gas has compressibility, and two cylinder 1 actions are inconsistent, cause movement travel different, two clamping plate 2 strokes are different, and namely anchor clamps can not self-centering.
