Crossbar upset testing fixture
The utility model relates to a kind of crossbar upset testing fixture, belongs to railway auxiliary device field.
The crossbar that railway freight-car is used needs to overhaul after using a period of time, checks mainly during maintenance that there is flawless the welding position.At present, do not have special-purpose inspection frock, inspection need be carried out on bin, because crossbar is longer, middle welding position can not carry out close-ups, and needs two people to cooperate just and can finish at least during upset, wastes time and energy.
The utility model content
The crossbar upset testing fixture that the technical problems to be solved in the utility model provides and a kind ofly overhauls conveniently, overhaul efficiency is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of crossbar upset testing fixture, and it comprises frame, be installed on the switching mechanism on the frame and be positioned clamp system on the switching mechanism; Described switching mechanism comprises rotary bracket and supporting brake system; Described rotary bracket comprises a rectangular frame, be fixed in the rectangular frame left side mounting platform, be fixed in the mount pad on rectangular frame right side and be welded in guide rail on the mounting platform, rotary bracket is installed on the frame by bearing seat and brake system; Described brake system comprise reductor and with the braking motor of the supporting setting of reductor, the output shaft and the rotary bracket of reductor are affixed; Described clamp system comprises stationary jaw, removable claw and via the sliding bar of air cylinder driven, stationary jaw is welded on the mount pad, and removable claw is welded on the sliding bar, and sliding bar slides on the guide rail.
Above-mentioned guide rail be arranged two in parallel.
Above-mentioned sliding bar is a T shape structure.
Adopt the beneficial effect that technique scheme produced to be: after adopting the utility model, the crossbar upset is convenient, and can be in arbitrarily angled stop by the control of braking motor, and easy access personnel closely multi-angle check the welding position, thereby the minimizing loss improves repair quality.

Wherein, 1, frame; 2, rotary bracket, 2-1, rectangular frame, 2-2, mounting platform, 2-3, guide rail, 2-4, stiffener, 2-5, mount pad; 3, cylinder; 4, sliding bar; 5, stationary jaw; 6, removable claw; 7, reductor; 8, output shaft; 9, bearing seat; 10, crossbar.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, on frame 1, be provided with switching mechanism and be fixed in clamp system on the switching mechanism, switching mechanism comprises rotary bracket 2 and supporting brake system, rotary bracket 2 is rotatable motion under the driving of brake system, rotary bracket 2 can be realized the parking of optional position under the control of brake system, make things convenient for maintainer's upkeep operation, brake system is made up of reductor 7 and supporting braking motor (not shown).Clamp system comprises two stationary jaws 5, two removable claws 6 and sliding bars 4, and clamp system is used for the crossbar 10 of examine is fixed on the rotary bracket 2.
Referring to accompanying drawing 1, the rectangular frame 2-1 of the main body of rotary bracket 2 for being made by square steel or the weldering of other shaped steel is welded with stiffener 2-4 on this rectangular frame 2-1, and it is a plurality of that stiffener 2-4 can be provided with as required, to guarantee the intensity of rotary bracket 2; Be provided with two mount pad 2-5 that are used to install and fix claw 5 on rectangular frame 2-1 right side, be provided with mounting platform 2-2 in the left side of rectangular frame 2-3, on mounting platform 2-2, be provided with two parallel guide rail 2-3, two stationary jaws 5 are welded on the mount pad 2-5, two removable claws 6 are welded on the sliding bar 4 of setting, sliding bar 4 is a T shape structure, sliding bar 4 links together with the cylinder bar of cylinder 3, sliding bar 4 can move around along guide rail 2-3 in the effect of cylinder 3, move thereby drive removable claw 6, thereby crossbar 10 can be clamped or unclamp.One end of rotary bracket 2 is fixed in by bearing seat 9 on the left side of frame 1, and the other end is positioned the right side of frame 1 by reductor 7, and reductor 7 drives via the braking motor (not shown), and can realize the parking of optional position.
Referring to accompanying drawing 2, during use, at first crossbar 10 is put on the rotary bracket 2, operate cylinder 3 then, with its clamping, start braking motor then and make rotary bracket 2 rotations, carry out the defect inspection of welding position.After inspection finishes, rotary bracket 2 is got back to horizontal level, removable claw 6 is unclamped, crossbar 10 is hung away, can carry out next Work inspection device.
