Abstract
The utility model discloses a pressure-limiting valve mounting seat locating sample rod which is capable of settling the disadvantages of existing C70 pressure-limiting valve mounting seats, such as difficult assembly, low efficiency, big man-hour consumption, failures of overall test over the next working procedure. The utility model has the advantages of simple structure, easy operation, easy assembly and high assembly efficiency, etc. The sample rod comprises a square-tube (I), a square-tube (II) and reinforcing ribs which form a triangular structure; a retaining-plate device is arranged at the joint between the square-tube (I) and the reinforcing ribs; and a locating device is arranged at the joint between the square-tube (II) and the reinforcing ribs.
Description
Technical field
The utility model relates to a kind of railway freight-car equipment, especially relates to a kind ofly turning over welder's preface assembling associate member with pressure limiting valve mount pad location sample bar at C70 type open-top car car body underframe.
Background technology
At present when assembly welding C70 pressure limiting valve mount pad, serve as the location benchmark with 120 valve seat centers, determine that with long rule the position of pressure limiting valve mount pad rules then, carry out spot welding again, assemble relatively more difficult like this.
Summary of the invention
The purpose of this utility model is exactly in order to solve the difficulty of present C70 pressure limiting valve mount pad assembling, efficient is low, expend man-hour, can produce a series of problems such as the subsequent processing whole detection does not pass a test, provide a kind of have simple in structure, easy to use, be convenient to assembling, can effectively improve the pressure limiting valve mount pad location sample bar of advantage such as packaging efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of pressure limiting valve mount pad location sample bar, it comprises square tube I, square tube II and reinforcement, the three forms triangular structure; Be provided with fixing plate device at square tube I and reinforcement junction; Then be provided with positioner at square tube II and reinforcement junction.
Described fixing plate device is a fixed head, and it connects firmly by rivet and square tube I, and the fixed head two ends are respectively equipped with an alignment pin I.
Described positioner comprises stiffener and location-plate, and both are installed in the two ends of a pair of rectangular steel pipe, and wherein stiffener is connected with square tube II, and the two ends of location-plate are provided with a pair of diagonal orientation pin II.
Described stiffener and square tube II junction are provided with gusset.
Be provided with circlip between described alignment pin II and location-plate.
The beneficial effects of the utility model are: this sample bar utilizes two alignment pins on the fixed bit plate and two diagonal orientation pins on the location-plate to locate pressure limiting valve seat and 120 valve seats respectively, general structure has stability and enough intensity, the longitudinal pitch and the horizontal spacing of 120 valves and pressure limiting valve have been guaranteed, it is convenient smoothly that the back operation is detected, operate light, economical and practical.
