Detailed Description
As shown in fig. 1-2, the cylinder liner product precision detection device of this embodiment structurally includes a workbench, a transverse cylinder 1 is provided on the workbench, a piston column of the cylinder is connected with a detection cylinder 2, a side wall of the detection cylinder 2 is provided with a laser ranging probe 3, the laser ranging probe belongs to the prior art and the conventional technology in the field, and the structure and principle thereof are not detailed. A top rod 4 is arranged in the detection cylinder 2 along the axis in a sliding manner, the length of the top rod is greater than that of the detection cylinder, and the outer end of the top rod can extend out of the detection cylinder when the top rod slides along the axis direction of the detection cylinder; the lateral wall of detecting a section of thick bamboo 2 is equipped with two sets of supporting mechanism in front and back, and every supporting mechanism of group includes along the three support arm 5 that the same circumference department of detecting a section of thick bamboo equiangular interval set up, and the equiangular interval of three support arm distributes, and the tip of three support arm is in on the same circumference that uses the axle center of detecting a section of thick bamboo as the centre of a circle. The lateral wall that detects a section of thick bamboo sets up logical groove 6, and support arm 5 articulates in logical groove 6 department, and the one end of support arm 5 runs through to detecting a section of thick bamboo inside to telescopic connection has top arm 7, and top arm 7 is articulated with ejector pin 4, and the articulated shaft of ejector pin 4 and top arm 7 is all perpendicular with the axis that detects a section of thick bamboo. The supporting arm 5 and the top arm 7 adopt telescopic structures, and when the ejector rod moves back and forth, the top arm can be pushed to open and close; and a top plate 8 is arranged on one side of the upper edge of the workbench opposite to the cylinder, and a reset pressure spring 9 is arranged at one end of the ejector rod far away from the top plate.
When the inner diameter precision of the cylinder liner is detected, the cylinder liner to be detected is transversely placed in front of the detection cylinder, the starting cylinder pushes the detection cylinder to move forwards, the supporting arm is in a folding state at the moment, the outer circle diameter of the whole detection cylinder (including the supporting arm) is smaller than the inner diameter of the cylinder liner, therefore, the detection cylinder can smoothly stretch into the cylinder liner, when the outer end of the ejector rod props up the top plate, the ejector rod moves inwards relative to the detection cylinder, the supporting arm is pushed to open, after the end of the three supporting arms contacts the inner wall of the cylinder liner, a three-point centering effect is achieved, the centering of the front and rear two groups of supporting arms can ensure that the axle center of the detection cylinder coincides with the axle center of the cylinder liner, and therefore the accuracy of. After the detection is finished, the cylinder contracts, the ejector rod rebounds to drive the supporting arm to be folded under the action of the reset pressure spring, and the detection cylinder is smoothly recovered.
In this scheme, laser rangefinder probe 3 is located between two sets of supporting mechanism around. In addition, a front guide sleeve 10 and a rear guide sleeve 10 are arranged in the detection cylinder 2, and the ejector rod 4 is sleeved in the guide sleeves 10. The guide sleeve is used for supporting the ejector rod to slide along the axis direction of the detection cylinder, and the contact surface of the guide sleeve and the ejector rod is provided with a ball, so that friction is reduced. In order to prevent the support arm from scratching the cylinder liner, an arc-shaped contact is arranged at the end of the support arm 5.
