Description

Technical Field

[0001] The utility model relates to the field of concentricity detectors, in particular to a concentricity detector which is convenient for fixing a measured object. Background Technique

[0002] The concentricity detector is used for the concentricity finding work of two shafts of various rotating equipment such as centrifugal pumps, compressors, fans, generators, etc. (also known as coupling alignment). It has the characteristics of reasonable structure, high precision, small error, wide application range, convenient use and maintenance, etc. It is an ideal special measuring tool and is widely used in mechanical industries such as petrochemical, power generation, papermaking, textile, etc.

[0003] The concentricity detector can adapt to workpieces of different lengths for detection. Since one end of the workpiece is usually fixed during fixing, and the other end is in a suspended state, this will make the longer workpiece unstable. At the same time, when performing straightness detection, people need to manually move the dial indicator. The manual movement will make the moving speed uneven, which may affect the detected data. For this reason, we propose a concentricity detector which is convenient for fixing a measured object. Content of the Utility Model

It can effectively solve the problems in the background technique.

[0011] Beneficial effects: Compared with the prior art, the utility model provides a concentricity detector that is convenient for fixing a measurement object, and has the following beneficial effects:

[0012] 1. For the concentricity detector that is convenient for fixing a measurement object, through the provided support assembly, a longer workpiece can be supported, avoiding the possible instability of the workpiece due to the influence of gravity, which may affect the detection. When the longer workpiece is installed on the workpiece positioning structure, by rotating the bolt at the rear end of the moving block, the moving block can move on the base. Move the moving block to the other end of the workpiece, pull the U-shaped support rod upward. Since the block and the rectangular groove are elastically connected, when the block reaches the position of the rectangular through hole, due to the reset effect, the block is snap-connected to the rectangular through hole, fixing the U-shaped support rod. At this time, the U-shaped support rod contacts the lower end of the workpiece, and the U-shaped support rod supports the workpiece.

[0013] 2.

[0026] Working principle

[0027] A concentricity detector for facilitating the fixation of a measured object, including a base 1, characterized in that: on one side of the outer surface of the upper end of the base 1, a workpiece positioning structure 2 is installed, and a first sliding block 3 is movably connected to the outer surface of the upper end of the base 1. The outer surface of the upper end of the first sliding block 3. This utility model is a concentricity detector for facilitating the fixation of a measured object. When it is necessary to detect a longer workpiece, first, one end of the workpiece is installed on the workpiece positioning structure 2 for fixation, and then the other end of the workpiece is supported by the support assembly 5. By rotating the bolt at the rear end of the moving block 9, the moving block 9 can move on the base 1. Move the moving block 9 to the other end of the workpiece, and pull the U-shaped support rod 12 upward. Since the block 14 and the rectangular groove 13 are elastically connected, when the block 14 reaches the position of the rectangular through hole 10, due to the reset effect, the block 14 is clamped with the rectangular through hole 10, and the U-shaped support rod 12 is fixed. At this time, the U-shaped support rod 12 contacts the lower end of the workpiece, so that the U-shaped support rod 12 supports the workpiece. When the support assembly 5 is not needed, press the block 14 so that the block 14 enters the sleeve groove 11, and slide the U-shaped support rod 12 into the sleeve groove 11, so that the U-shaped support rod 12 is retracted and slides to one side of the base 1, which will not affect the detection. Move the first sliding block 3 to drive the first dial indicator 4 to move and contact the workpiece, and rotate the rear turntable of the workpiece positioning structure 2 to rotate the workpiece. At this time, the first dial indicator 4 performs detection. Then contact the second dial indicator 7 with the workpiece, start the motor 16 to make the lead screw 17 rotate, thereby driving the second sliding block 6 and the second dial indicator 7 to move. The second dial indicator 7 can detect the straightness of the workpiece. The second sliding block 6 moves more stably through the chute 19, the slider 20, and the guide rod 18, without the need for manual movement, which is more convenient. At the same time, the moving speed is more uniform, improving the detection effect.
