Description
Technical field
The present invention relates to cylinder fittings field, especially relate to a kind of cylinder trunnion support structure。
Background technology
At present, the trunnion mounting of cylinder adopts the formula of filling the span of a man's arms to fix mostly, namely symmetrical support is utilized in the cylinder body both sides of cylinder, and fastened by fixing bolt, such as Chinese patent notification number: CN201412413, authorized announcement date on February 24th, 2010, disclose a kind of movable central trunnion, including main body, four briquettings, screw compositions, described main body is respectively equipped with little axle up and down, and main body and four briquettings are fastened by screw。But, such fixed structure is easily because loosening under the impact repeatedly moved of cylinder piston, trunnion mounting is axially slided at cylinder body, the entirety of cylinder is moved, the long stroke of piston rod lost efficacy, thus causing equipment failure, scrapping, even cause even more serious security incident, cause greater loss。
Summary of the invention
The present invention is the above-mentioned deficiency in order to overcome prior art, it is provided that a kind of can effectively prevent the fixing comparatively firm cylinder trunnion support structure of trunnion mounting and cylinder body generation axial slip, position。
To achieve these goals, the present invention is by the following technical solutions:
A kind of cylinder trunnion support structure of the present invention, including the trunnion mounting being separately positioned on cylinder body both sides, described trunnion mounting includes body and two positioning ends, positioning end lays respectively at the two ends of body and arranges in the same direction, the top of described body is provided with gudgeon, the opposite flank of two positioning ends is respectively equipped with the clamping block mounting groove axially in parallel with cylinder body, clamping block mounting groove in be provided with can opposite gripping blocks mounting groove rotate clamping block, described cylinder body is provided with and the locating slot clamping block fit inside, trunnion mounting is provided with the bolt acted on outside clamping block, the extrados that the outwardly formation of one side of described clamping block fits tightly with clamping block mounting groove sidewall。Clamping block is arranged in clamping block mounting groove, is bolted clamping block side so that clamping block opposite side snaps onto in the locating slot of cylinder body, completes the fixed installation for cylinder body。Such that make the bolt looseness of trunnion mounting side, trunnion mounting still can keep and being reliably connected of cylinder body, without there is trunnion mounting situation of significantly sliding on cylinder body。By clamping the leverage of block; so that bigger active force can be produced between clamping block and cylinder body; therefore trunnion mounting is fixing also more reliable; simultaneously in process clamping block fastened by bolt; the assembling torque requirement of bolt is also less; not only reduce labor intensity during assembling, and the protected effect for bolt and screw thread is also better。
As preferably, described bolt and clamping block contact position to distance in the horizontal direction between extrados and locating slot sidewall contact position more than extrados and locating slot sidewall contact position to distance in the horizontal direction between extrados and clamping block mounting groove sidewall contact position。Owing to bolt is for clamping the arm of force arm of force more than locating slot counteracting force of block active force so that clamping block becomes laborsaving lever。
As preferably, the side that described body is relative with gudgeon is provided with inner concave, and being respectively provided on two sides with of inner concave transits to the intrados clamping block mounting groove。When assembling, cylinder side wall enters into inner concave and carries out pre-determined bit in space, conveniently installs。The intrados of both sides can be fitted with the corner of cylinder body simultaneously, thus the diametrically opposite position of trunnion mounting and cylinder body is positioned, improves the radially coaxial degree of trunnion mounting and cylinder body。
As preferably, described clamping block is provided with the clamping face relative with extrados, and the clamping face of clamping block fits tightly with locating slot, and described clamping face is provided with clamping block protuberance layer, additionally, described intrados is provided with intrados protuberance layer。Clamping block protuberance layer and intrados protuberance layer can be the anti-skid structures such as projection particle or dentate stripe, thus increasing the frictional force between clamping face and locating slot, clamping block mounting groove and between intrados and cylinder body, improve the trunnion mounting clamping reliability for cylinder body further。
As preferably, described trunnion mounting is respectively equipped with relative hole, location in the bottom surface of positioning end, is provided with pillar between the trunnion mounting of described cylinder body both sides, and pillar is suitable with hole, location。Between the trunnion mounting of cylinder body both sides, pillar is set, improve the integral rigidity of trunnion mounting on the one hand, reduce the amplitude of deformation of trunnion mounting, positioning action can be played on the other hand when mounting ear bracing strut, ensure that trunnion mounting is accurate with cylinder body position, improve the axiality of gudgeon on two trunnion mountings。
As preferably, described hole, location is pin-and-hole, and described pillar is alignment pin, is connected by alignment pin between the trunnion mounting of both sides。Easily the trunnion mounting of both sides can be positioned by alignment pin so that the trunnion mounting of both sides is integrally forming。As an alternative, hole, location can be adopted as screw, and pillar adopts screw rod, is connected by screw rod between the trunnion mounting of both sides。Can certainly adopting while being screw, being through hole or both sides are all through holes, thus utilizing bolt and nut to be fixed。
Therefore, there is advantages that (1) is greatly promoted the clamping force for cylinder body by clamping the leverage of block, effectively prevent the situation of trunnion mounting and cylinder body generation sliding；(2) its screw-down torque of bolt acting on clamping block reduces, and effectively prevents bolt from skidding, the comparatively laborsaving convenience of installing/dismounting；(3) the radially coaxial degree between axiality and trunnion mounting and the cylinder body of gudgeon is substantially increased。
