Technical Field
The utility model relates to a processing part preapre for an unfavorable turn of events shape presss from both sides tight positioner belongs to part clamping technical field.
Background
The precision requirement of mechanical manufacturing class product to processing is very high, all require that we can not have the removal and not hard up relative anchor clamps of product when processing the product, this just needs our anchor clamps to press from both sides tight product completely when compressing tightly, but because the material of product, factors influences such as shape, position, the contact surface of clamp plate and product is difficult to realize whole face laminating when anchor clamps compress tightly, the product is because the casting difference, the same position of same product also can have the difference, if the clamp plate is the plane and compresses tightly the contact of product and will appear line contact, the product is pressed the deformation, and the deformation has randomness.
the platen, which is one of the component parts of the jig, plays an important role. The pressing plate is driven by an oil cylinder or an air cylinder to tightly press the product,
the processing size of the product is influenced by the magnitude of the pressing force in the pressing process, the product cannot be pressed when the pressing force is small, and the product can be pressed in the processing process
The vibration and size deviation are generated, and the product is compressed and deformed due to large pressing force. Due to the diversity of the product structure and the pressing surface
The uncertainty of the shape, we cannot find the optimal pressure value for each product.
With the continuous development of human technology, machine processing is gradually replacing manual work, and more product processing is changed from traditional manual processing and semi-manual processing into automatic processing of machines. The automatic processing of machine has driven the development of anchor clamps, current anchor clamps mainly divide into atmospheric pressure anchor clamps and hydraulic fixture, the atmospheric pressure anchor clamps are driven by the cylinder, hydraulic fixture is by hydraulic oil provides pressure, no matter atmospheric pressure or hydraulic pressure compress tightly all can produce very big packing force, the pressure head of traditional clamp plate is made the facet more, this kind of pressure point is suitable for regular horizontal pressing surface, but there are many die casting products in the casting because the die drawing angle of product and reasons such as clamping part selection cause, can't guarantee the level of product pressing surface, can't accomplish perpendicularly to push down and be perpendicular with the plane when pressing surface on the clamp plate and product contact under this condition, can cause the deformation that compresses tightly of product when compressing tightly, so just need one kind can compress tightly the device that can not produce and compress tightly the deformation by arbitrary angle shape.
SUMMERY OF THE UTILITY MODEL
To the above defect, the utility model aims to provide a rational in infrastructure, it is various to have solved the product that compresses tightly and compress tightly the face shape, and is irregular, the deformation that compresses tightly that the unstability arouses.
Therefore, the utility model adopts the technical scheme that: the anti-deformation clamping and positioning device for the machined parts is characterized by comprising an oil cylinder (1), a positioning block (2), a pressing plate (3) and spherical pressing points (4);
The pressing plate (3) is driven by the oil cylinder (1) to operate, and the spherical pressing points (4) are arranged on the pressing plate (3) and operate along with one point of the pressing plate (3);
the spherical pressing points (4) and the positioning blocks (2) are correspondingly arranged to clamp the workpiece.
The pressing plate (3) is positioned on the front side of the oil cylinder (1) and is driven by the oil cylinder (1) to move back and forth;
The positioning block (2) is arranged on the side surface of the oil cylinder (1), and the corresponding spherical pressure point (4) is arranged on the side surface of the pressure plate (3).
And the pressing plate (3) is also provided with a driving mechanism (5) for finely adjusting the spherical pressing point (4).
the pressing plate (3) is provided with a guide track for the spherical pressing point (4) to move back and forth, and the spherical pressing point (4) is driven by the driving mechanism (5) to move back and forth along the guide track.
The utility model has the advantages that: the part deformation-preventing clamping and positioning device adopts the hemispherical pressure points, so that point contact with a product is ensured, the point contact with the product is still maintained when the shape of the pressed point is irregular, the inclined plane and the thickness are changed, and the possibility of stress deformation of the product is greatly reduced; the utility model discloses used the part to preapre for an unfavorable turn of events shape and pressed from both sides tight positioner, improved the stability of product clamping greatly, improved the qualification rate of product.
The utility model discloses can realize keeping the product to compress tightly not warp when the product compresses tightly the product under the anomalous condition of face shape. The pressing plate is not required to be manually intervened and controlled, the inclined pressing surface is met, or the pressing surface with the irregular shape is not required to be specially designed in the angle of the pressing plate, the pressing is not required to be deformed by adjusting the pressure, and the deviation does not occur in the size in the machining process.
