Description
Technical field
The utility model belongs to precision optical machinery and manufactures manufacture field, and the flexibility related between a kind of lathe and workpiece is fast
Change locating and clamping apparatus, specifically the powerful clamping device of the flexible quick position of a kind of mistake proofing.
Background technology
Flexible quick change locating and clamping apparatus is most commonly used to clamp the quick change supporting plate with one or more workpiece, workpiece can be fixed on the exact position in machine tooling district, and seat, quick change supporting plate and the clamping of foundation base phase based on the connector being fixed to machine tooling district.
Chinese patent 201210387014.4 discloses a kind of combined pneumatic chuck, and it mainly comprises base, catch mechanism and pneumatic mechanism, and wherein catch mechanism is made up of ball, inner position ring, outer positioning ring and spring etc.This chuck operationally, utilizes the elastic force effect of the gravity of outer positioning ring and spring downward, and extruding ball clamping stagnation, in the ball installing hole of inner position ring, reaches the object of tight lock electrode; During ventilation after gas lifting outer positioning ring and spring, ball retreats, and eliminates the tight lock status to electrode, reaches the object of disassembling.This combined pneumatic chuck Problems existing is, inner walls and outer positioning ring outer wall belong to rigid seal and coordinate, outer positioning ring reciprocates for a long time and can cause inner walls and the wearing and tearing of outer positioning ring outer wall, causes air-tight chamber sealing property to decline and causes gas to promote outer positioning ring.Owing to not adopting seal approach between inner position ring outer wall and outer positioning ring inwall, so the ball installing hole that other can be provided with along inner position ring ring wall when gas push outer positioning ring moves releases, cannot piston movement be promoted and clamp system opening function cannot be realized; Secondly outer positioning ring when reciprocating owing to there is no guider, angular motion centered by axis can be there is under the effect of spring torsion, spring is in heeling condition and affects the stable and clamping force of clamp system, and can damage spring, thus clamping function is lost efficacy cause security incident to occur.
Chinese patent 03121636.6 discloses a kind of jockey.This device comprises chuck and is connected to the dismountable work rest fixture on chuck, the work rest with holding pin is fixed in the fixture of chuck, chuck is provided with for holding holding pin and having the centre bore that conical inserting portion inserts, and is clamped by holding pin and is firmly held in the clamp system in centre bore.Holding pin has the datum level of fitting with the conical inserting portion of chuck, for the X axis of work rest or Y-axis location.Chuck upper surface is provided with Z-direction locating surface, for locating the Z-axis direction of work rest.This chuck assembly Problems existing is, can only position the direction of in X axis or Y-axis, as needed X axis, Y-axis locates simultaneously, just must combine two or more jockey and use together, and the installation site required precision of combination unit is high.Cannot position angle during single or multiple gripper chuck clamping of workpieces frame simultaneously, cause the angle of work rest or workpiece to be in free state, pinpoint function cannot be played.Because above-mentioned location is rigidity location, positioning precision is not high, makes this device be not suitable for use in precision optical machinery processing; Secondly, after workpiece supporting plate is connected with chuck, workpiece supporting plate or workpiece are just located angle, but the positive negative direction of the X of workpiece, Y-axis is not unique state, as trade union college mistake can cause scrapping of workpiece.
Chinese patent 200410090540.X discloses a kind of jockey.This device comprises chuck and workpiece supporting plate, and chuck is provided with at least 3 centrepins, and workpiece supporting plate is provided with the groove corresponding with centrepin position and shape.Workpiece supporting plate is connected with chuck in removably mode, and detent mechanism and clamp system are all rigidity, can bear certain load.When workpiece supporting plate is connected with chuck, both can work in coordination thus determine the former the Z-direction position relative to the latter.The width of the centrepin of chuck is less than the groove width of workpiece supporting plate, therefore when workpiece supporting plate to be connected with chuck position time, centrepin on chuck only with the single contacts side surfaces of corresponding groove, gap is had between centrepin and another side, so only have four laminatings in eight of four grooves sides, this location belongs to rigidity location, uncertain, the positioning precision that cause locating is reduced, makes this device be not suitable for doing accurate repeated positioning device.In addition, after workpiece supporting plate is connected with chuck, workpiece supporting plate or workpiece are also just located angle, but the positive negative direction of the X of workpiece, Y-axis is not unique state, as trade union college mistake can cause scrapping of workpiece.
Chinese patent 200810039898.8 also discloses a kind of jockey.This device is by chuck, workpiece supporting plate and blind rivet composition, containing four positioning tooths on chuck, move towards with radial direction, even cloth is listed in the end face of chuck circumferentially, four are had with the Z-direction stop surface of radial direction trend between adjacent positioning tooth, containing boss on workpiece supporting plate, groove and blind slot, article four, groove moves towards with radial direction, even cloth is listed in the end face of workpiece supporting plate circumferentially, boss is divided into four parts, there is blind slot on the both sides of every bar groove, it is thin-walled between groove and blind slot, during use, together with four positioning tooths patch with four grooves, four boss end faces and four Z-direction stop surfaces are close to, the plastic deformation of blind slot wall, the workpiece be fixed on workpiece supporting plate is made to obtain X axis, the flexibility location of Y-axis and Z-axis direction and rigid grasp.But this device existing problems are: 1, after workpiece supporting plate is connected with chuck, workpiece supporting plate or workpiece are just located angle, but the positive negative direction of the X of workpiece, Y-axis is not unique state, as trade union college mistake can cause scrapping of workpiece; This device locates X-axis because causing under meeting blind slot wall bearing capacity in heavily processing, Y direction precision reduces; 2, when Z-direction is located, this device is adopted as the contact in 4 faces, due to reasons such as mismachining tolerances or cause and wherein have face to contact completely with chuck locating surface thus to cause Z-direction positioning precision to reduce; The flexible locating slot coordinated with chuck positioning tooth that the carrier of workpiece or supporting plate are provided with belongs to thin-wall construction, and when heavy cut, radial force is large, can cause locating slot that large distortion occurs, cause positioning precision to reduce.
In sum, the shortcoming of existing clamping, jockey is: 1, due to poor sealing performance, easily occurs the problem of not opening of chuck in using; 2, the damage causing spring can be rotated during piston axially-movable, affect the blessing function of clamp system; 3, when quick change supporting plate is connected with chuck, X-axis, the positive negative direction of Y-axis are without error-disable function, the positive negative direction of X-axis, Y-axis can be caused not to be unique state, as trade union college mistake can cause scrapping of workpiece; 4, the contact in 4 faces is adopted as at Z-direction location timer, due to reasons such as mismachining tolerances or cause and wherein have face to contact completely with chuck locating surface thus to cause Z-direction positioning precision to reduce.
