In order to achieve the purpose, the basic scheme of the invention is as follows: the generator end cover clamping device comprises a base, a supporting mechanism, a resetting mechanism and a limiting mechanism, wherein the base comprises a base, a supporting cylinder is arranged on the base, a slide way is arranged on the inner wall of the supporting cylinder, the sliding direction of the slide way is parallel to the axial direction of the supporting cylinder, the top surface of the slide way is a plane, the bottom surface of the slide way penetrates through the base, and two wedge blocks with the same inclination angle are arranged between every two adjacent slide ways;
the supporting mechanism comprises a supporting plate, the edge of the upper end of the supporting plate is uniformly provided with upward extending sliding claws in an array mode, the sliding claws are connected with the inner cavity of the supporting cylinder in a sliding mode, the upper end face of each sliding claw is an inclined face matched with the inclined face of the wedge block, the bottom face of the supporting plate is fixedly connected with a first spring, and one end, far away from the supporting plate, of the first spring is fixedly connected to the;
the reset mechanism comprises a support column, and push claws are arranged at the bottom end of the support column in the circumferential direction and are connected to the inner wall of the support cylinder in a sliding manner;
stop gear includes stopper, gag lever post and limiting plate, and the limiting plate is evenly arrayed in a support section of thick bamboo periphery, and the gag lever post is L shape, gag lever post one end fixed connection support column outer wall, and the other end sliding connection of gag lever post is in the limiting plate inner chamber, and the gag lever post is close to the lateral wall that supports a section of thick bamboo and is the inclined plane, and the stopper is with horizontal direction sliding connection in limiting plate lateral wall, is equipped with the second spring between stopper and the limiting plate inner chamber.
The working principle and the beneficial effects of the basic scheme are as follows: the generator end cover is stably placed at the top of the supporting column, and is pressed downwards. When the supporting column is stressed to move downwards to a certain position, the push claw can prop against the sliding claw, and then the sliding claw drives the supporting disk to move downwards together. Because the terminal surface of sliding claw is the inclined plane, consequently when exerting downward pressure, horizontal skew can take place for the sliding claw, and then the sliding claw drives the supporting disk and takes place to rotate.
When the sliding claw rotates into the position of the slideway, the pressing-down is stopped. The support mechanism will be moved upwards to a higher position before being pressed down by the first spring. Meanwhile, the limiting rod is fixed on the supporting column, so that the limiting rod can continue to move upwards. When the inclined plane of the limiting rod moves upwards, the limiting block is pushed to move outwards, and then the top surface of the limiting rod is abutted against the engine end cover.
When the generator end cover is removed, the generator end cover is only required to be pressed again, and the sliding claw returns to be between the inclined planes of the wedge blocks again. The reset mechanism descends, and the limiting block is retracted under the action of the second spring. Thereby achieving the effect of taking out the end cover of the generator.
Compare in this kind of mode of fixing the generator end cover through threaded connection mode among the prior art, the operating procedure of this scheme is very simple and convenient, only needs to press once to the generator end cover can reach the effect to its fixed or take out. Meanwhile, the fixing device has a good fixing effect on the premise of simple and convenient operation, and is convenient for an operator to carry out trimming operation on the end cover of the generator.
Further, the end part of the support column is conical. Compare and constantly control horizontal plane to fixed establishment regulation among the prior art, this design only needs insert the generator end cover output shaft hole on the circular cone, can reach the effect of steadily placing.
Furthermore, the end face of the push claw is an inclined plane. The design can increase the joint area between the push claw and the sliding claw, and can achieve better pushing effect when pushing.
Furthermore, one end, close to the limiting rod, of the limiting block is an inclined plane, and the inclined plane of the limiting block is matched with the inclined plane at the end part of the limiting rod. The design has the advantages that the contact area of the matched inclined surfaces is large, so that the limiting rod can have larger thrust to push out the limiting block.
Furthermore, the outer wall of the limiting block is made of rubber buffer materials. On one hand, the limiting block is prevented from clamping the generator end cover due to overlarge pressure, and on the other hand, the friction force is increased to prevent the generator end cover from sliding.
Furthermore, the bottom surface of the limiting block far away from one end of the limiting plate extends downwards to form a protrusion. The surface of the end cover of the generator is generally an uneven surface, so that when the limiting block slides to a certain position horizontally, the protrusion can be clamped at the groove on the surface of the end cover of the generator, an effective fixing effect is achieved, and the transverse displacement of the end cover of the engine is avoided when the end cover is clamped.
