Abstract
The utility model discloses a crank arm welding clamp. Positioning keys are arranged on the two sides of a substrate respectively; positioning key ways on a left positioning sleeve and a right positioning sleeve are sleeved on the positioning keys; the left positioning sleeve and the right positioning sleeve are positioned on the substrate through bolts; a diamond-shaped positioning pin is fixedly arranged on the substrate between the left positioning sleeve and the right positioning sleeve; plug positioning pins are plugged in positioning holes of the left positioning sleeve and the right positioning sleeve; the included angles between the positioning holes and the positioning key ways are consistent with the included angle of a crank arm pin hole and a crank arm shaft connecting rod mounting hole; and a support column is arranged at the four corners of the substrate respectively. The crank arm welding clamp has the characteristics of simple structure, convenience in mounting and accuracy and high efficiency in positioning.
Description
Technical field
The utility model belongs to mesohigh switchgear assembly manufacturing technology field, especially relates to a kind of mesohigh switchgear assembly technological equipment valve mechanism connecting lever weld jig.
Background technology
Make the field at the mesohigh switchgear assembly, especially in mesohigh switchgear assembly valve mechanism connecting lever welding processing, to be the connecting lever that will process and connecting lever axle be contained in the design attitude of cabinet respectively at erecting yard to present situation, connecting lever and connecting lever axle welded together after adjusting the position with the valve mechanism connecting rod more again.Owing to there is not positioner, the requirement difficulty of space angle that guarantees pin-and-hole on the connecting lever and the connecting rod installing hole on the connecting lever axle is bigger, the symmetry difficulty that particularly will guarantee left and right connecting lever parts is bigger, often but do not reach ideal effect through repeatedly adjusting, often because opening and closing valve mechanism, the problems referred to above cause obstacle, the effort of not only taking a lot of work, and influence serviceability.
Summary of the invention
The purpose of this utility model is to improve existing technical deficiency and a kind of simple in structure, easy for installation, accurate positioning, connecting lever weld jig efficiently is provided.
The utility model is to realize like this, a kind of connecting lever weld jig, the both sides that it is characterized in that substrate are respectively equipped with positioning key, left side positioning sleeve, positioning spline on the right positioning sleeve is sleeved on the positioning key, left side positioning sleeve, right positioning sleeve also is positioned on the substrate by bolt, the rhombus alignment pin is fixed on left positioning sleeve, on the substrate between right positioning sleeve, the plug alignment pin is inserted into left positioning sleeve, in the locating hole on the right positioning sleeve, locating hole is consistent with angle and the angle between connecting lever pin-and-hole and connecting lever axle connecting rod installing hole between positioning spline, respectively is provided with a pillar at substrate four jiaos.
The utility model is compared in prior art has following distinguishing feature and good effect: the utility model adopts the both sides of substrate to be respectively equipped with positioning key, left side positioning sleeve, positioning spline on the right positioning sleeve is sleeved on the positioning key, left side positioning sleeve, right positioning sleeve also is positioned on the substrate by bolt, the rhombus alignment pin is fixed on left positioning sleeve, on the substrate between right positioning sleeve, the plug alignment pin is inserted into left positioning sleeve, in the locating hole on the right positioning sleeve, locating hole is consistent with angle and the angle between connecting lever pin-and-hole and connecting lever axle connecting rod installing hole between positioning spline, four jiaos at substrate respectively are provided with a pillar, the upper surface of its substrate, left side positioning sleeve, the inner surface of right positioning sleeve, the periphery of prismatic alignment pin constitutes the plane and two pits location structure, six spatial degrees of freedom of connecting lever parts have been limited, the full location of having realized the connecting lever parts; Positioning key is fixedly arranged on the substrate, in the positioning spline of its movable set on left positioning sleeve, right positioning sleeve, realize left positioning sleeve, the location of right positioning sleeve in substrate, with bolt left and right positioning sleeve is fastened on the substrate; Have waist shape locating hole on left side positioning sleeve and the right positioning sleeve, waist shape locating hole has a space angle consistent with the space angle of connecting lever pin-and-hole and connecting lever axle connecting rod installing hole with positioning spline, realize connecting lever axle connecting rod installing hole and the connecting lever pin-and-hole angle location in anchor clamps by the plug alignment pin, like this, also just guaranteed the spatial design angle of connecting lever pin-and-hole and connecting lever axle connecting rod installing hole after the welding; Waist shape locating hole on a left side positioning sleeve and the right positioning sleeve prevented the pitch-row error of connecting lever axle connecting rod installing hole on the other hand and produce cross the location; Left and right sides positioning sleeve symmetric arrangement in anchor clamps, left and right sides connecting lever parts welding processing is finished in same anchor clamps, install to machine at left positioning sleeve and be the arm of turning left, install to machine at right positioning sleeve and be the arm of turning right, they share and make same prismatic alignment pin, have guaranteed the symmetry of left and right sides connecting lever reliably; Whole anchor clamps are placed on the workbench with 4 pillars, and are simple in structure, easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 bows to partial sectional view for Fig. 1.
The specific embodiment
Embodiment, a kind of connecting lever weld jig, with reference to Fig. 1, Fig. 2, the both sides that are substrate 1 are respectively equipped with positioning key 5, left side positioning sleeve 2, positioning spline on the right positioning sleeve 6 is sleeved on the positioning key 5, left side positioning sleeve 2, right positioning sleeve 6 also is positioned on the substrate 1 by bolt, rhombus alignment pin 4 is fixed on left positioning sleeve 2, on the substrate 1 that right positioning sleeve is 6, plug alignment pin 8 is inserted into left positioning sleeve 2, in the locating hole 3 on the right positioning sleeve 6, locating hole 3 is consistent with angle and the angle between connecting lever pin-and-hole and connecting lever axle connecting rod installing hole between positioning spline, four jiaos at substrate 1 respectively are provided with a pillar 9, and this constitutes a kind of structure of the present utility model.
During use, be example with the arm of turning left, the arm of will turning left earlier is placed on the last plane of substrate 1, the pin-and-hole of arm of turning left is sleeved on the rhombus alignment pin 4, turn left macropore on the arm facing to the endoporus of positioning sleeve 2, again the macropore of connecting lever axle by connecting lever is inserted in the endoporus of positioning sleeve 2 and leans against on the upper surface of connecting lever until the shoulder inner face on it, to plug alignment pin 8 again inserts in the connecting rod installing hole of connecting lever axle lower end by the waist shape locating hole on the positioning sleeve 2, like this, just realized the full location of connecting lever parts in anchor clamps, taken off workpiece after welding is finished and get final product; Left and right connecting lever is corresponding processing one by one, and left and right sides connecting lever is quantitatively in full accord, is very easy to production management, has the characteristics of novel structure, accurate positioning, easy for installation, efficient work.
