Abstract
The invention relates to a plane-contact weight reduction device. The plane-contact weight reduction device comprises a supporting rod, a base body, a spring and an adjusting screw, wherein the supporting rod is arranged in the base body in a sliding fit manner, the lower end of the base body is in threaded connection with the adjusting screw, the spring is assembled between the adjusting screw and the supporting rod, a steel ball fixing rack is placed at the top of the supporting rod, a plurality of steel balls are mounted in the steel ball fixing rack, a supporting block, which covers the upper part of the steel ball fixing rack and the upper part of the supporting rod, is supported above the steel balls, two rings of elastic plungers are mounted on the sidewall of the supporting block, one ring of the elastic plungers is abutted against the sidewall of the steel ball fixing rack, and the other ring of the elastic plungers is abutted against the sidewall of the supporting rod. According to the plane-contact weight reduction device, the supporting block in contact with parts is supported above the steel balls, the supporting block is enabled to be capable of horizontally moving towards any direction in the horizontal plane, the frictional resistance to the parts is reduced, and the parts can move more easily during locating action, so that the parts can be accurately located, and the reference holes of the parts can be effectively protected from being damaged.
Description
Technical field
The present invention relates to frock clamp, specifically a kind of Plane-contact weight reduction device.
Background technology
In the fixture of machining large part (as wind-driven generator body), in order to reduce part deadweight to the impact of location components and parts, and the datum hole of available protecting part makes its injury-free (such as part impression), often adopts weight reducing device.
Existing weight reducing device as shown in Figure 1, comprise rest pad 1, cramp bar 2, matrix 3, spring 4 and adjustment screw 5, cramp bar 2 is slidably fitted in the top of matrix 3, the bottom thread of matrix 3 is connected with adjustment screw 5, spring 4 is equipped with between adjustment screw 5 and cramp bar 2, cramp bar 2 stretches out under the effect of spring 4 above matrix 3, and rest pad 1 is fixed on the top of cramp bar 2.This weight reducing device requires higher to the positioning datum of part, and during location, part does not move substantially, is difficult to the occasion that adaptation part positioning reference holes changes greatly.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of Plane-contact weight reduction device, this device can ensure part accurate positioning and the datum hole of energy available protecting part.
According to technical scheme of the present invention: a kind of Plane-contact weight reduction device, comprise cramp bar, matrix, spring and adjustment screw, described cramp bar to be slidably fitted in described matrix and to stretch out from the upper end of described matrix, the lower end of described matrix has been threaded adjustment screw, described spring is equipped with between described adjustment screw and described cramp bar, the top of described cramp bar is placed with steel ball fixed mount, the steel ball of plane on multiple outstanding described steel ball fixed mount is installed in described steel ball fixed mount, described multiple steel ball is supported with the rest pad covering described steel ball fixed mount and described cramp bar top, the sidewall of described rest pad is provided with two circle resilient plunger, the described resilient plunger of one circle withstands on the sidewall of described steel ball fixed mount, another encloses described resilient plunger and withstands on the sidewall of described cramp bar.
The side-walls that described steel ball fixed mount and described cramp bar contact with described resilient plunger is processed with plane respectively.
Described two circle resilient plunger are distributed on described rest pad.
Often enclose described elastic and be plugged with six.
Described steel ball has six.
Technique effect of the present invention is: the rest pad with feature contacts is bearing on steel ball by the present invention; make rest pad can to any direction translation in horizontal plane; reduce the frictional resistance of part; make part more easily movement when location action, thus make the accurate positioning of part and can the datum hole of available protecting part make it injury-free.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing weight reducing device.
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ Fig. 2, comprise rest pad 1, cramp bar 2, matrix 3, spring 4, adjustment screw 5, steel ball fixed mount 6, steel ball 7, resilient plunger 8 etc.
As shown in Figure 2, the present invention is a kind of Plane-contact weight reduction device, comprise cramp bar 2, matrix 3, spring 4 and adjustment screw 5, cramp bar 2 to be slidably fitted in matrix 3 and to stretch out from the upper end of matrix 3, the lower end of matrix 3 has been threaded adjustment screw 5, spring 4 is equipped with, by the elastic force regulating adjustment screw 5 to adjust cramp bar 2 between adjustment screw 5 and cramp bar 2.
The top of cramp bar 2 is placed with steel ball fixed mount 6, and be provided with the steel ball 7 of plane on multiple outstanding steel ball fixed mount 6 in steel ball fixed mount 6, steel ball 7 generally has six.Multiple steel ball 7 is supported with the rest pad 1 covering steel ball fixed mount 6 and cramp bar 2 top.
The sidewall of rest pad 1 being provided with two circle resilient plunger 8, two circle resilient plunger 8 is distributed on rest pad 1, and often enclosing resilient plunger 8 generally has six.One circle resilient plunger 8 withstands on the sidewall of steel ball fixed mount 6, and another circle resilient plunger 8 withstands on the sidewall of cramp bar 2.The side-walls that steel ball fixed mount 6 and cramp bar 2 contact with resilient plunger 8 is processed with plane respectively.
Operation principle of the present invention is as follows: the present invention is the device that a kind of elastic force by spring 4 carries out loss of weight, and be in contact with it when part is placed on rest pad 1 as face contact, due to the deadweight of part, part and rest pad 1 form entirety.The power F produced during location action, the entirety that part and rest pad 1 are formed is rolled and is easy to workpiece is moved along the direction of putting forth effort F on steel ball 7.The separate design of steel ball fixed mount 6 and rest pad 1, cramp bar 2 is reasons that steel ball 7 can form rolling between cramp bar 2 and rest pad 1.The resilient plunger 8 contacted with steel ball fixed mount 6 and the resilient plunger 8 contacted with cramp bar 2 make them return back to home position separately when part is separated with rest pad 1, i.e. shown position.
Rest pad 1 with feature contacts is bearing on steel ball by the present invention; make rest pad 1 can to any direction translation in horizontal plane; reduce the frictional resistance of part; make part more easily movement when location action, thus make the accurate positioning of part and can the datum hole of available protecting part make it injury-free.The present invention can adapt to part positioning reference holes has larger change and the very high occasion of the surface requirements be in contact with it part.
