Abstract
The invention discloses a rapid self-centering clamp for a cylinder sleeve. A positioning seat is mounted on a base; a centering disk is arranged on the positioning seat; the centering disk is connected with a plurality positioning sliding blocks; the positioning sliding blocks are connected with the base through sliding pins; a positioning handle is arranged on the centering disk in a locking manner. The rapid self-centering clamp for the cylinder sleeve has the characteristics of reasonable structural design, high positioning accuracy and low production cost; on the premise of not increasing blank sorting or blank reference machining, and the positioning accuracy is improved in a self-centering manner.
Description
Technical field
What the present invention relates to frock clamp manufactures and designs field, particularly relates to a kind of cylinder sleeve Quick self-centering fixture.
Background technology
The endoporus boring processing of cylinder sleeve, most often DGT524 two-spindle borer is adopted at present, its basic locate mode is the mode adopting positioning sleeve, namely with the outer garden of cylinder sleeve for positioning datum, be positioned in the positioning seat 2 be arranged in base 1, its position error is the aperture, location of positioning seat 2 and the diameter difference in the outer garden of cylinder sleeve.Because the outer garden of cylinder sleeve be now blank outer garden size, tolerance range be ± 1mm, and therefore position error is very large, causes endoporus processing capacity uneven, both affects cutter life, and work is useless even to produce Tang Bu garden time serious or forge a knife etc.For overcoming the above problems, industry adopts two schemes generally: a kind of is classify to the outer garden of cylinder liner blank, adopts different positioning seats, though this method can reduce position error, can not realize precision centering completely.Meanwhile, the manufacture input of positioning seat and the operation consumption of blank sorting is increased; Another kind is the operation increasing by one Che Wai garden benchmark and flat both ends of the surface before bore hole operation, and come to position with standard base with the outer garden of benchmark comparatively unified after car, this mode, owing to realizing the roughing of part, reduces follow-up rough machined processing capacity; Meanwhile, relatively improve positioning precision, therefore apply the most general.But, in actual production, there is following shortcoming: 1, owing to adding a procedure, increase the input of equipment, improve manufacturing cost; 2, can not eliminate position error completely, position error is large.
Summary of the invention
The object of the present invention is to provide the cylinder sleeve Quick self-centering fixture that a kind of reasonable in design, positioning precision are high, production cost is low, this fixture, under the prerequisite not increasing blank sorting or rough benchmark processing, realizes the raising of positioning precision by self-centering mode.
For achieving the above object, a kind of cylinder sleeve Quick self-centering of the present invention fixture, described base is provided with positioning seat, and positioning seat is provided with centering disk; Described centering disk is connected with several positioning sliding blocks, and positioning sliding block is connected with base through sliding pin; On described centering disk, locking is provided with position fixing handle.
Described base is provided with stop screw.
In technique scheme, by being provided with positioning seat on base, centering disk is fixedly located on base by stop screw; Described centering disk is connected with several positioning sliding blocks, and positioning sliding block is connected with base through sliding pin; Described centering disk side is provided with position fixing handle.After adopting said structure, when certain kind cylinder sleeve will be processed, being installed by hexagon socket head cap screw by the positioning seat of dimension is locked on base, cylinder sleeve to be processed is positioned in positioning seat, now the bottom surface of cylinder sleeve contacts with the locating surface of positioning seat, achieve the centering of end face, and the endoporus of the outer garden of cylinder sleeve and footstock has the gap of about 4mm, be convenient to place; During location, by promoting position fixing handle counterclockwise, the position fixing handle be locked on centering disk drives centering disk to rotate in the endoporus of base, eccentric grove on such centering disk drives sliding pin to move, and then drive three positioning sliding blocks to make synchronizing moving, promote cylinder sleeve to main shaft concentric position, until centering disk can not continue to rotate, after making each slide block all touch the outer garden of cylinder sleeve, cylinder sleeve realizes precision centering.
Further, described base is provided with stop screw, and by the effect of stop screw, centering disk can not depart from base in moving process, improves cylinder sleeve centering precision further.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylinder sleeve Quick self-centering fixture of the present invention;
Fig. 2 is top view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, cylinder sleeve Quick self-centering fixture of the present invention is described in further detail.
From Fig. 1, Fig. 2, a kind of cylinder sleeve Quick self-centering fixture of the present invention, described base 1 is provided with positioning seat 2, and positioning seat 2 is provided with centering disk 3; Described centering disk 3 is connected with several positioning sliding blocks 4, and positioning sliding block 4 is connected with base 1 through sliding pin 5; On described centering disk 3, locking is provided with position fixing handle 6.
When using of the present invention, being coordinated by its locating surface by base 1 is arranged on bed piece, now its outer garden, location and endoporus are coaxial with machine tool chief axis, and the positioning seat 2 of dimension is installed by hexagon socket head cap screw and is locked on base 1, cylinder sleeve 8 to be processed is positioned in positioning seat 2, now the bottom surface of cylinder sleeve 8 to be processed contacts with the locating surface of positioning seat 2, achieves the centering of end face; Meanwhile, the outer garden of cylinder sleeve 8 to be processed and the endoporus of footstock 2 have the gap of 4mm, are convenient to place.During location, counterclockwise promotion position fixing handle 6, because position fixing handle 6 is locked on centering disk 3, therefore along with the rotation of position fixing handle 6 drives centering disk 3 to rotate in the endoporus of base 1, eccentric grove on such centering disk 3 drives sliding pin 5 to move, and then drive some positioning sliding blocks 4 to make synchronizing moving, promote cylinder sleeve 8 to main shaft concentric position to be processed, until centering disk 3 can not continue to rotate, after making some positioning sliding blocks 4 all touch the cylindrical of cylinder sleeve 8 to be processed, cylinder sleeve 8 to be processed realizes precision centering.
See Fig. 2, operation principle of the present invention is: the center of circle of base 1, positioning seat 2 is concentric with machine tool chief axis; On centering disk 3, arc groove has an offset relative to the cylindrical that it coordinates with base 1, when centering disk 3 is after the center of circle of base 1, positioning seat 2 rotates to an angle, sliding pin 5 can be made to produce displacement, as long as the distance of its displacement is greater than its fit clearance, then can realize centering, because three eccentric groves are uniformly distributed, then locating piece 2 is synchronizing movings, thus realizes 3 self-centerings of cylinder sleeve 8 to be processed.
In the present embodiment, described base 1 is provided with stop screw 7, and due to the effect of stop screw 7, centering disk can not depart from base in moving process, improves centering precision further.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.
