Abstract

The invention discloses a multi working face ribbed angle iron which is an assembly used in a hole-series modular fixture. The basal body of the angle iron is made into an inverse trapezoid, three vertical faces are vertical to an upper plane and a lower plane, and a vertical plane connected with one long edge of the upper plane and a side surface connected with the vertical face vertical to the lower plane are made into an inclined surface; a groove is made on the inclined surface, and convex edges are arranged around the inclined surface; the vertical face of the bottom surface of the basal body of the angle iron, which is connected with two short edges of the upper plane, is made into a crisscross pin key groove, and the vertical face connected with two short edges of the upper plane is made into a vertical key groove; the convex edge on the lower surface of the inclined surface groove is manufactured with two waist-shaped passing holes which are respectively on two sides of one pin key groove; screw holes are respectively manufactured on the upper convex edge and the lower convex edge of two inclined surface grooves; screw holes and positioning holes are manufactured on the upper plane and are in cross spread in row, and screw holes in row are manufactured on the bottom surface of the inclined surface, where the groove is manufactured. The invention has the advantage of improving the assembly ability for the hole-series modular fixture.

Description

Multi working face ribbed angle iron

Technical field:

The invention is the parts that are used for dowel-pin modular fixture.

Background technology:

At present, using the hole is in the process of element assembling fixture, to direction anyhow greater than the workpiece of 200mm, when locating surface, hole, back gauge run into variation, solve quite difficulty, to consider various factors to anchor clamps and process and influence when design, assembling, as: 1. matrix combination in a plurality of location of anchor clamps is to the influence of machining accuracy; 2. when clamp body is too high to the stability and the influence of intensity; 3. the size of cutting force is to the influence of agent structure; 4. element connected mode, the intensity of clamping work pieces, convenience are whether to the influence of operating efficiency; Make the built-up jig complex structure, the big deficiency that waits of volume.

Summary of the invention:

The purpose of the invention provides a kind ofly can simplify built-up jig, improves the multi working face ribbed angle iron of anchor clamps serviceability; The purpose of the invention is to realize by following technical scheme: multi working face ribbed angle iron, comprise the angle bar matrix, it is characterized in that the angle bar matrix is made up-small and down-big trapezoidal shape, make vertical plane and the lower plane gone up with two minor faces in last plane facade that is connected and the facade that is connected with a long limit, the side bevel of vertical plane that is connected with another long limit, last plane and vertical elevation connection that is connected with lower plane, on the inclined-plane, make groove, periphery leaves chimb, the vertical plane that long limit of groove floor and last plane is connected constitutes parallel plane, make the pin key groove of right-angled intersection in angle bar matrix bottom surface, with facade that two minor faces in last plane are connected on make the pin key groove of above-below direction, make two waist shape bolt via holes on the chimb below inclined plane groove, two waist shape bolt via holes are distributed in the both sides of a pin key groove, with facade that two minor faces in last plane are connected on make in the pin key groove of above-below direction and make nine screws, make two screws on the pin key groove vertical on the chimb below inclined plane groove with two waist shape bolt via holes, close inclined-plane and facade are four locating holes from the two row's orderings of left end system on last plane, three screws are spaced, between two registration holes and screw, make five locating holes of a row, with facade that a long limit is connected on make four locating holes of first row from top to bottom, three screws are spaced, second row makes seven locating holes, down is spaced by first row and second row.

The advantage of the invention: owing to make trapezoidal shape at the angle bar matrix, constitute many working faces, on the angle bar matrix, make pin key groove, waist shape bolt via hole, screw and locating hole, have multi-faceted assembling connection and regulatory function, can bringing into play up and down, the pin key bearing pin connects, the effect of location, the assembling mode simple and flexible is pressed from both sides, holds out against convenient and reliable; Because of many locating holes, many screws on the working face distribute, expanded each orientation and hole slot combination of elements, promoted dowel-pin modular fixture assembling ability.

The specific embodiment:

Multi working face ribbed angle iron, comprise the angle bar matrix, it is characterized in that the angle bar matrix is made up-small and down-big trapezoidal shape, as shown in Figure 1, make vertical plane and the lower plane gone up with two minor faces in last plane facade that is connected and the facade that is connected with a long limit, the side bevel of vertical plane that is connected with another long limit, last plane and vertical elevation connection that is connected with lower plane, on the inclined-plane, make groove, periphery leaves chimb, the vertical plane that long limit of groove floor and last plane is connected constitutes parallel plane, make the pin key groove of right-angled intersection in angle bar matrix bottom surface, with facade that two minor faces in last plane are connected on make the pin key groove of above-below direction, make two waist shape bolt via holes on the chimb below inclined plane groove, two waist shape bolt via holes are distributed in the both sides of a pin key groove, with facade that two minor faces in last plane are connected on make in the pin key groove of above-below direction and make nine screws, make two screws on the pin key groove vertical on the chimb below inclined plane groove with two waist shape bolt via holes, close inclined-plane and facade are four locating holes from the two row's orderings of left end system on last plane, three screws are spaced, between two registration holes and screw, make five locating holes of a row, with facade that a long limit is connected on make four locating holes of first row from top to bottom, three screws are spaced, second row makes seven locating holes, down is spaced by first row and second row.

The invention combined hole is that the structural element of component module design, production line pallet is researched and developed; The most outstanding characteristics one are the positioning accuracy height of anchor clamps; Make trapezoidal shape, stability is strong, it is easy to connect to make pin key groove, waist shape bolt via hole, screw and locating hole and lathe on the angle bar matrix, realize positioning limit, be convenient to select the elements that match such as bushing plate, stomidium supporting to be connected with processing mode in each orientation according to the size of workpiece, applied range can be adjusted to workpiece 90 °, 180 °, 270 ° position processing on lathe; Second when being to use, and because of waist shape bolt via hole, screw and locating hole and the fixation of pin key groove are arranged, can prevent quivering anti-deformation, improves machining accuracy.Digital control processing such as finish car, grind, mill, multi working face ribbed angle iron can be adjusted in the radius of turn scope among the figure, according to specification requirement, on its two main locating surface, increase any location respectively, spacing, compressing structure cooperates with numerical control programming Ding, finishes processing tasks such as workpiece profile, curved surface, cambered surface or fabrication hole.
