Abstract
A positioning datum-floating fixture comprises a base plate, a positioning mechanism and hold-down mechanisms; the positioning mechanism is arranged on the base plate; the hold-down mechanisms are symmetrically arranged on the left and the right sides of the positioning mechanism; the positioning mechanism comprises an air cylinder, a retainer, positioning pins, guide pins and a positioning body; the positioning body is arranged at the middle of the upper surface of the base plate; the telescopic part of the air cylinder positioned on the bottom of the positioning body is connected with the retainer into a whole; the positioning pins and the guide pins which run through the positioning body are vertically arranged on the retainer; each hold-down mechanism comprises an oil cylinder and a hold-down arm; and the hold-down arms are connected with the piston rods of the oil cylinders. The design of the fixture is novel, and the structure is reasonable; after the fixture positions and clamps a casting product, the parts of the casting product, including bottom holes for positioning, which need to be machined, can be machined in one step, the casting product does not need to be positioned and clamped time after time, consequently, the equipment resource and the labor cost are saved, the machining efficiency is increased, and therefore the fixture is highly worth popularizing.
Description
Technical field
The utility model relates to a kind of positioning fixture, especially a kind of unsteady anchor clamps of benchmark of locating.
Background technology
A lot of cast articles have polymorphic structure, are difficult for the location, and processing causes inconvenience to subsequent fine.As improvement, often on cast article, reserve bottom outlet, as the location benchmark, carry out follow-up fine finishining with bottom outlet.Yet generally the anchor clamps of making according to this method can't guarantee to process in same operation as the bottom outlet and the hole end surface of location benchmark, need again could carry out fine finishining to bottom outlet behind the clamping location.Though can finish the processing of cast article, time-consuming taking a lot of work, the product uniformity is not high.
Summary of the invention
At the weak point of existing cast article location technology, the purpose of this utility model provides a kind of anchor clamps that benchmark floats of locating, and makes it can be to finishing follow-up fine finishining after the disposable positioning and clamping of cast article.
For achieving the above object, technical solution adopted in the utility model is: a kind of unsteady anchor clamps of benchmark of locating, comprise base plate, positioner and hold down gag, and positioner is located on the base plate; The left and right sides of positioner is arranged with hold down gag; Described positioner is made up of cylinder, limiting plate, alignment pin, guide finger and positioning body; Positioning body is located at the middle part of plate upper surface; The extensible member and the limiting plate that are positioned at the cylinder of positioning body bottom are connected as a single entity; Vertically be provided with the alignment pin and the guide finger that pass positioning body on the limiting plate; Described hold down gag is made up of oil cylinder and pressure arm; Pressure arm is connected with the piston rod of oil cylinder.
Further, the locating surface that contacts with cast article of described positioning body is provided with coarse anti-skidding lines.
Further, the via hole top that cooperates with alignment pin and guide finger in the described positioning body is stepped hole.
The beneficial effects of the utility model are: owing to adopt said structure, cast article can be located on positioning body by positioner, and is firm by the hold down gag clamping then; Alignment pin in the positioner and guide finger can withdraw from locating hole by the limiting plate that cylinder drives lifting, thereby can not cause any interference to the following process of bottom outlet; The locating surface of positioning body is provided with coarse anti-skidding lines, can prevent effectively that cast article from adding the slip in man-hour; Via hole top in the positioning body is stepped hole, can be used for dodging the burr that the cast article bottom orifice may exist, and also can avoid process tool.The utility model modern design, rational in infrastructure, after to cast article location, clamping, the position of the required processing of cast article comprises that the bottom outlet that is used to locate can disposablely machine, need not repeatedly positioning and clamping, thereby save device resource and cost of labor, improve working (machining) efficiency, have excellent generalization values.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, also is that specification digest is with scheming.Each label is respectively among the figure: (1) base plate, (2) cylinder, (3) limiting plate, (4) alignment pin, (5) guide finger, (6) positioning body, (7) oil cylinder, (8) pressure arm, (9) anti-skidding lines, (10) stepped hole, (11) cast article.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to accompanying drawing, a kind of unsteady anchor clamps of benchmark of locating of the utility model comprise base plate 1, positioner and hold down gag, and positioner is located on the base plate 1; The left and right sides of positioner is arranged with hold down gag; Described positioner is made up of cylinder 2, limiting plate 3, alignment pin 4, guide finger 5 and positioning body 6; Positioning body 6 is located at the middle part of base plate 1 upper surface; The extensible member and the limiting plate 3 that are positioned at the cylinder 2 of positioning body 6 bottoms are connected as a single entity; Vertically be provided with the alignment pin 4 and the guide finger 5 that pass positioning body 6 on the limiting plate 3; Described hold down gag is made up of oil cylinder 7 and pressure arm 8; Pressure arm 8 is connected with the piston rod of oil cylinder 7.
Working method of the present utility model is as follows: at first, cylinder 2 actions promote limiting plate 3 and upwards action of alignment pin 4, withstand positioning body 6 until limiting plate 3, stop action, alignment pin 4 emersion positioning bodies 6 certain distances; Then, with cast article 11 positioning body 6 of packing into, by positioning body 6, alignment pin 4 location; Then, oil cylinder 7 action compresses product by pressure arm 8; At last, limiting plate 3 and alignment pin 4 are return in cylinder 2 actions, and alignment pin withdraws from the product orientation hole, finish the clamping location of product, can carry out follow-up machined.
The above, it only is a kind of preferred embodiment of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology any trickle modification, equivalent variations and modification that top embodiment did.
