Abstract
The utility model discloses an anchor clamps are used in processing of thin wall barrier part excircle, including fixed baseplate, with support mandrel and arm lock that fixed baseplate links to each other, the last wholeheartedly axle sleeve section of thick bamboo of rigid coupling of going back of fixed baseplate, support the mandrel with the telescopic axis of mandrel is on same straight line, support the mandrel through a power device can remove the fixed baseplate both sides, support the mandrel and have a plurality of elastic support claws, when not receiving circumference constraint power, the support claw is followed support the expansion of mandrel circumference direction, when receiving circumference constraint power, the support claw is followed support the shrink of mandrel circumference direction. The utility model discloses a deformations problems of appearance in the barrier part course of working, simple structure, convenient to use can effectively be avoided with anchor clamps to a section of thick bamboo type processing.
Description
Technical field
The present invention relates to a kind of thin-wall barrel Excircle machining fixture.
Background technology
At present, cylindrical parts workpiece adds man-hour carrying out turning class, because tube kind part wall thickness is thinner, radial rigidity is more weak, by the impact of the factors such as cutting force, heat in metal cutting and clamping force in process, opposing solid shaft member more easily produces machining deformation, moreover, existing three grab chuck mode clamping tool often can only the cylinder class workpiece of clamping very in close limit, can not meet actual production demand.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of thin-wall barrel Excircle machining fixture, and this fixture can alleviate the problem on deformation that a like members occurs in process greatly.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of thin-wall barrel Excircle machining fixture, comprise fixed pedestal, the support mandrel be connected with described fixed pedestal and jig arm, an also affixed spindle collet on described fixed pedestal, the axis of described support mandrel and described spindle collet on the same line, described support mandrel can be moved in described fixed pedestal both sides by power set, described support mandrel has some flexible support claws, when not by circumferential binding force, described support claw is expanded along described support mandrel circumferential direction, when being subject to circumferential binding force, described support claw shrinks along described support mandrel circumferential direction.
Preferably, cylinder class workpiece clamps from cylinder class workpiece outer circumference surface by described jig arm, and described jig arm comprises at least two that arrange along cylinder class workpiece axis relative direction.
Preferably, described jig arm comprises two that arrange along cylinder class workpiece axis relative direction.
Preferably, described jig arm can be moved up and down along described fixed pedestal by lowering or hoisting gear.
Preferably, described lowering or hoisting gear comprises lift cylinder or elevating screw.
Preferably, described power set are motor.
The beneficial effect that the present invention reaches:
Cylinder like members fixture for processing of the present invention effectively can avoid the problem on deformation occurred in barrier part process, and structure is simple, easy to use;
Cylinder class workpiece can clamp from cylinder class workpiece outer circumference surface by jig arm, and resiliency supported pawl to carry out to barrier part supports further from barrier part inside fixing, when the position around support member being added to the machining deformation probability that can greatly reduce barrier part man-hour;
Jig arm is connected with lowering or hoisting gear, if there are two jig arm, then the lifting that two jig arm can be relative, can adapt to the cylinder class workpiece of larger diameter scope.
Accompanying drawing explanation
Fig. 1 is the side sectional view (when support claw has opened holding state) of thin-walled Excircle machining fixture in embodiment;
Fig. 2 is the side sectional view (during support claw collapsed state) of thin-walled Excircle machining fixture in embodiment;
Fig. 3 is support mandrel end view in Fig. 2;
Wherein: 1. fixed pedestal, 2. jig arm, 3. support mandrel, 31. support claws, 4. spindle collet, 5. a class workpiece.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As Figure 1-3, a kind of thin-wall barrel Excircle machining fixture, comprise fixed pedestal 1, the support mandrel 3 be connected with fixed pedestal 1 and jig arm 2, an also affixed spindle collet 4 on fixed pedestal 1, the axis of support mandrel 3 and spindle collet 4 on the same line, support mandrel 3 can be moved (i.e. the left and right sides) in fixed pedestal 1 both sides by power set, support mandrel 3 has some flexible support claws 31, when not by circumferential binding force, support claw 31 is expanded along support mandrel 3 circumferential direction, when being subject to circumferential binding force, support claw 31 shrinks along support mandrel 2 circumferential direction.Preferably, power set are motor (not shown).
Preferably, cylinder class workpiece 5 clamps from cylinder class workpiece 5 outer circumference surface by jig arm 2, and jig arm 2 comprises two that arrange along cylinder class workpiece 5 axis relative direction.
Preferably, jig arm 2 can be moved up and down along described fixed pedestal 1 by lowering or hoisting gear.This lowering or hoisting gear comprises elevating screw.
Resiliency supported pawl end is not when by circumferential binding force, support claw is expanded along described support mandrel circumferential direction, plays a supporting role, as shown in Figure 1 to barrier part inwall, now support mandrel moves right, support claw departs from spindle collet, and namely its circumference is in the state of the power of not carrying the baby, and when support mandrel is moved to the left, support claw is incorporated in spindle collet, as shown in Figure 2, namely support claw is subject to circumferential binding force, now no longer plays a supporting role to barrier part inwall.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
