Abstract
The utility model discloses a clamp capable of preventing squashing products. The clamp comprises a pressing plate, a bridge plate, a left supporting device, a right supporting device, a bottom plate, a regulation mechanism, a circular shaft, a locking nut, a gasket and a swing bolt. By means of the floating type pressing plate, single-point and single-line contact when stress is performed is avoided, pressure is dispersed to large surfaces of products uniformly, the range of clamping force is greatly enlarged, and the products can be prevented from being squashed.
Description
Technical field
The utility model belongs to mechanical engineering field, is specifically related to the clamping structure device of frock clamp.
Background technology
The clamping force of frock clamp must be in certain scope, has both needed to guarantee that product added is not subjected to displacement man-hour, does not damage again product.Clamping mode is a lot, generally has the hand-operated clampings such as screw thread, spring, and the power such as pneumatic, hydraulic pressure, electric power clamp, and what wherein have can set power value, and some needs are by controlling manually.For the fastening situation of hand thread, as shown in Figure 1, if if firmly excessive at certain point, pressing plate produces distortion, and the corresponding position of just easy conquassation product appears single-point or single line contact, in unbalance stress.So need symmetrically, fastening nut or bolt progressively repeatedly, each screwing force can not be too large, is difficult to control.
Summary of the invention:
The purpose of this utility model is to provide a kind of clamp structure that prevents conquassation, by floating type pressure plate structure, makes screwing force dispersed, avoids occurring the contact of single-point single line, thereby has expanded the scope of screwing force, prevents conquassation product.
The purpose of this utility model is achieved through the following technical solutions:
Prevent a fixture for conquassation, comprise pressing plate, bridge plate, left support, right support, base plate, can be according to governor motion, circular shaft, nut, packing ring, the eyelet bolt of product adjustment height, described base plate is connected with left support, right support bottom;
Governor motion is set in left support and right support;
Bridge plate left side is provided with a locating hole, by circular shaft, governor motion and bridge plate is rotationally connected;
Pressing plate top and bridge plate bottom are provided with a corresponding locating hole, by circular shaft, pressing plate and bridge plate are rotationally connected;
Bridge plate right side has a groove matching with right support shape, by nut, packing ring, bridge plate and governor motion is pressed in right support;
Between eyelet bolt and right side governor motion, by circular shaft, be rotationally connected;
The pressing plate left and right sides is respectively equipped with the groove matching with governor motion shape.
Preferably, described left support and right support are double threaded screw, and described governor motion comprises sleeve nut and stop nut, and governor motion screws in left support and right support.
Preferably, described nut is sphere band shoulder nut, and described packing ring is suspension type packing ring.
Further, described fixture also comprises damping pin and spring leaf, the perforate of bridge plate top, and damping pin penetrates the hole on bridge plate, and one of spring leaf is stuck in the groove of damping pin head, and one is screwed on bridge plate.
Further, shape and the product of the one side that described pressing plate contacts with product are corresponding, and surface has groove, fluting can absorption portion be out of shape, reduce the difficulty of large area finished surface, and disperse contact area, when product processing vibration, can increase side-friction.
Compared with prior art, the beneficial effects of the utility model are that pressing plate transmits screwing force by circular shaft and bridge plate, pressing plate is in rotating floating type state, pressing plate can be fitted with product all the time like this, pressure is dispersed, and contact area is large, has avoided the generation of single-point single line contact situation, even compromise face, also can manufacture the pressing plate of respective shapes.Very big like this scope of widening screwing force, has effectively avoided the conquassation of product.For being easy to operate, adopted suspension type packing ring and sphere band shoulder nut to prevent that packing ring from dropping, spring leaf and damping pin produce frictional resistance to pressing plate and prevent that pressing plate from arbitrarily rocking, and by adjusting sleeve nut's screw-in length, can adapt to the product of differing heights simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, originally execute routine left support 12, right support 11 is selected double threaded screw, governor motion is selected sleeve nut 2 and stop nut 10, left support 12, right support 11 are screwed into the base plate B of equipment, according to the good sleeve nut 2 of the Height Adjustment of product, screw in the degree of depth of left support 12, right support 11, fixing with stop nut 10.Products A is put into behind centre position, bridge plate 3 and pressing plate 1 are put down, adjust product space and make after pressing plate and product laminating, rotation eyelet bolt 9, compresses bridge plate 3 with sphere band shoulder nut 7 and suspension type packing ring 8.
The above is only preferably embodiment of the utility model, for a person skilled in the art, can also make some distortion and improvement not departing under structure of the present utility model, and these also should be considered as protection domain of the present utility model.
