Compared with the prior art, the utility model have can detect slight skidding of tongs, guarantee advantages such as operation safety.
Description
Technical Field
The utility model relates to an engine cylinder body tongs especially relates to a detection mechanism of cylinder body tongs.
Background
When one cylinder body gripper grabs various cylinder bodies, if the clamping positions are different, sensors need to be arranged at a plurality of positions on a driving original piece such as a hydraulic cylinder, the efficiency is low, and the cost is increased; in addition, the function that current cylinder body tongs did not detect the work piece and drop, when the tongs did not grasp the cylinder body, the tongs had the condition of slightly skidding, if can not in time detect this moment, continued to remove and have very big potential safety hazard.
Disclosure of Invention
The utility model aims at providing a detection mechanism of engine cylinder body tongs for technical problem more than solving.
The utility model discloses mainly set up the mechanism on the arm claw of cylinder body tongs, concrete technical scheme is as follows:
the utility model comprises a first proximity sensor, a second proximity sensor and a drop detection component, wherein the first proximity sensor is arranged at the position, close to the lower end, of the left arm claw of the gripper through threads, and the second proximity sensor is arranged at the position, close to the lower end, of the right arm claw of the gripper through threads; the falling detection assembly is arranged at the position, close to the upper end, of the right arm claw of the gripper; the falling-off detection assembly comprises a base frame, a linear guide rail, an air cylinder, a support, a limiting block, a detection shaft, an end cover, a third proximity sensor and a displacement sensor, wherein the base frame is arranged on a right arm claw of the gripper, the linear guide rail which is longitudinally arranged is arranged on the base frame, the support is arranged on a sliding block of the linear guide rail, the air cylinder which is longitudinally arranged is arranged on the base frame, the piston end of the air cylinder is downwards arranged and is connected with the support, the displacement sensor which is fixedly arranged on the support is arranged on one side of the air cylinder, the limiting block which is fixedly arranged on the support is arranged on the other side of the air cylinder, the limiting block is provided with an upward central slotted hole, the top end of the slotted hole is connected with the end cover through threads, the third proximity sensor which is in threaded connection with the end cover is arranged in the center, the lower extreme of this detection axle stretches out to the outside of stopper by the slotted hole bottom of stopper to the boss lower extreme and the slotted hole bottom of detecting the axle meet, in order to realize detecting the spacing downwards of axle, detect epaxial pressure spring that still cup joints, the lower extreme of pressure spring meets with the boss upper end of detecting the axle, the upper end of pressure spring with the lower extreme of end cover meets.
The utility model discloses at the during operation, in left arm claw and right arm claw stretched into the cylinder of cylinder body, the right arm claw opened, and the tight cylinder body expands, and at this moment, first proximity sensor and second proximity sensor signals show that the tongs opens and targets in place. When the left arm claw and the right arm claw stretch into the cylinder body to be in place, the piston rod of the air cylinder stretches out downwards, the limiting block contacts the upper surface of the cylinder body, the detection shaft moves upwards, the third proximity sensor feeds back signals, and the displacement sensor records distance data between the sensor and the upper surface of the cylinder body. When the gripper is lifted, the cylinder body slightly slips downwards, the position of the piston of the air cylinder is kept unchanged, the distance detected by the displacement sensor is changed, a signal is output, and the gripper stops moving continuously.
The utility model can realize that when the gripper grabs various cylinder bodies, a sensor for detecting the cylinder bodies in place does not need to be additionally arranged on a driving piece such as a hydraulic cylinder, and the sensor does not need to be replaced due to different cylinder bodies; and the slight slip of the hand grab can be detected, and the operation safety is ensured.
