Abstract
The utility model relates to a collet chuck for boring an eccentric hole in a cylinder. The collet chuck is used for clamping a workpiece and comprises a positioning sleeve, a positioning plate and a positioning pin for positioning a workpiece pin hole, wherein a cavity for placing the workpiece is formed in the positioning sleeve; the eccentric distance of the cavity is consistent with the eccentric distance of the workpiece; the positioning plate is arranged at one end away from a workpiece inlet and is provided with the positioning pin; one end of the positioning pin extends out of the positioning plate and is horizontally inserted into the cavity; the outer wall of the positioning sleeve close to the positioning plate is circumferentially and uniformly provided with a plurality of first through holes; and the outer wall of the positioning sleeve close to the workpiece inlet is circumferentially and uniformly provided with a plurality of second through holes. According to the collet chuck, by forming the through holes in the positioning sleeve, the workpiece is clamped by three claws of a numerical control machine tool through the positioning sleeve, so that the clearance between the workpiece and the inner wall of the positioning sleeve is eliminated, the accuracy for repeated positioning of the workpiece is improved, the accuracy of the eccentric distance and the wall thickness of the cylinder workpiece is guaranteed, the qualification rate is greatly improved, and great convenience is brought to workers for clamping.
Description
Technical field
The utility model relates to a kind of bore hole collet chuck, relates in particular to a kind of cylinder boring eccentric orfice collet chuck.
Background technology
Cylinder is a vitals in the air motor, and air motor is the device that compressed-air actuated pressure energy is converted to the mechanical energy of rotation.Its effect is equivalent to motor or hydraulic motor, namely exports torque and rotates with driving mechanism.
The production of cylinder part will just can be finished through following operation, and cast blank-finish turning 1-finish turning 2-chamfering-brill lateral aperture-cylindrical grinding-boring eccentric orfice-mill both ends of the surface-deburring-cleaning-immersion oil is antirust.Wherein the boring eccentric orfice is one critical process.
Process one and need to utilize existing anchor clamps such as the cylinder workpiece of Fig. 1 and Fig. 2, existing anchor clamps are comprised of parts such as base plate, pin, positioning sleeve, pressing plate and alignment pins usually.Require this cylinder eccentric orfice of processing according to the cylinder detail drawing, the crucial required precision that will guarantee eccentric throw and wall thickness is at first aimed at alignment pin with the workpiece pin-and-hole on the workpiece and is put into the end, then clamps with pressing plate, because must be gapped between cylinder part and the positioning sleeve, the size of pressing plate thrust is difficult to guarantee the pinpoint uniformity of cylinder part, in addition simultaneously, workman's clamping is also inconvenient, efficient is low, so such installation way can not guarantee the qualification rate of cylinder part.
The utility model content
The technical problems to be solved in the utility model is: for the precision that solves cylinder part eccentric throw that existing anchor clamps produce and wall thickness not high, qualification rate is low, and the problem of workman's clamping inconvenience, the utility model provides a kind of cylinder boring eccentric orfice collet chuck to solve the problems referred to above.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cylinder boring eccentric orfice collet chuck, comprise positioning sleeve, location-plate and be used for the alignment pin of positioning workpieces pin-and-hole, has the cavity for place work piece in the described positioning sleeve, the eccentric throw of cavity is consistent with the eccentric throw of workpiece, described location-plate is arranged on the end away from workpiece import department, on the described location-plate alignment pin is set, one end of described alignment pin stretches out described location-plate level and inserts cavity, described positioning sleeve circumferentially is evenly equipped with a plurality of the first through holes near on the outer wall of location-plate, and described positioning sleeve circumferentially is evenly equipped with a plurality of the second through holes near on the outer wall of workpiece import department.
For better accurate positioning workpieces, described the first through hole has 3, and described the second through hole has 3.
Further, as preferably, described positioning sleeve is that spring steel is made.
The beneficial effects of the utility model are, the utility model cylinder boring eccentric orfice collet chuck, utilization is opened the hole at positioning sleeve, the Digit Control Machine Tool three-jaw comes clamping work pieces by positioning sleeve, eliminate the gap between workpiece and the positioning sleeve inwall, improved the precision of workpiece resetting, guaranteed the eccentric throw of cylinder workpiece and the precision of wall thickness, qualification rate improves greatly, and workman's clamping is also very convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the cylinder part that will process;
Fig. 2 is the cutaway view at the cylinder part A-A place that will process;

Schematic diagram when Fig. 4 is the utility model cylinder boring eccentric orfice collet chuck processing cylinder workpiece.
Among the figure 1, positioning sleeve, 2, location-plate, 3, the workpiece pin-and-hole, 4, alignment pin, 5, cavity, the 6, first through hole, the 7, second through hole.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-4, the utility model cylinder boring eccentric orfice collet chuck, be used for clamping workpiece, comprise positioning sleeve 1, location-plate 2 and be used for the alignment pin 4 of positioning workpieces pin-and-hole 3, has the cavity 5 for place work piece in the positioning sleeve 1, the eccentric throw of cavity 5 and workpiece is consistent, location-plate 2 is arranged on the end away from workpiece import department, alignment pin 4 is set on the location-plate 2, one end of alignment pin 4 stretches out location-plate 2 levels and inserts cavity 5, positioning sleeve 1 circumferentially is evenly equipped with 3 the first through holes 6 near on the outer wall of location-plate 2, and positioning sleeve 1 circumferentially is evenly equipped with 3 the second through holes 7 near on the outer wall of workpiece import department, and positioning sleeve 1 is made by spring steel.
First the cylinder workpiece is put into cylinder boring eccentric orfice collet chuck, the alignment pin 4 that workpiece pin-and-hole 3 is aimed in the cylinder boring eccentric orfice collet chucks is put into the end, cylinder workpiece and cylinder boring eccentric orfice collet chuck is installed to together to clamp on the three-jaw of numerically controlled lathe again to carry out bore hole.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
