Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder pipes, in particular to a pipe wall thickness measuring mechanism for oil cylinder pipes. Background Art

[0002] Cylinder tube is a kind of high-precision steel tube material after cold drawing or hot rolling. Because the inner and outer walls of precision steel tube have no oxide layer, can withstand high pressure without leakage, high precision, high finish, no deformation after cold bending, no cracks after expansion and flattening, etc., it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. When manufacturing cylinder tubes, the wall thickness of the cylinder tubes will be tested. The conventional wall thickness measurement mechanism is a wall thickness micrometer.

[0003] When measuring the wall thickness of the cylinder tube, the threaded rod on the wall thickness micrometer is rotated to drive the two ends of the micrometer to clamp at the two end walls of the tube wall. After reading the scale, the threaded rod on the wall thickness micrometer is rotated in the opposite direction to separate the end wall of the micrometer from the tube wall. Finally, the micrometer is removed and the threaded part is rotated to make the micrometer contact and separate from the tube wall. This is time-consuming. When the cylinder tube is manufactured, the wall thickness measurement base is large, and the slow measurement speed is not conducive to efficient thickness measurement of the large base of the cylinder tube wall. Utility Model Content

[0004] The utility model aims to provide a pipe wall thickness measuring mechanism for an oil cylinder pipe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pipe wall thickness measuring mechanism for an oil cylinder pipe comprises a straight plate, a grip is provided at the bottom of the straight plate, a spring column is arranged at the left end of the straight plate, a sliding seat is arranged at the outer side of the spring column, a slider is arranged at the side of the sliding seat close to the straight plate, a header is installed at the front end wall of the sliding seat, through holes are provided at the middle of the sliding seat and the slider, a scale mark is opened at the front end wall of the straight plate, a fixed frame is installed at the right end of the straight plate, a threaded rod is arranged at the right end of the fixed frame, a pad column is installed at the end side of the threaded rod, a slideway is opened in the middle of the straight plate, and a slide rod is installed at the inner side of the slideway.

[0007] Preferably, the straight plate is fixedly connected to one end of the spring column, and the slide seat forms an elastic structure through the spring column and the straight plate.

[0008] Preferably, the slide seat and the slider are fixedly connected, and the slide seat and the header are fixedly connected.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. The slide seat and the slider are fixed to form an integral body. When in use, the elastic force of the spring column causes the slide seat to slide down along the vertical direction of the straight plate.

The fixed frame on the upper end of the displacement straight plate moves down, and the two fixed frames are brought close to each other. When measuring the thickness of the cylinder wall, it is only necessary to place the two fixed frames on the two ends of the pipe wall respectively.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 2 As shown, the straight plate 1 is fixedly connected to one end of the spring column 3, and the slide seat 4 forms an elastic structure with the straight plate 1 through the spring column 3, the slide seat 4 and the slider 5 are fixedly connected, and the slide seat 4 and the header 6 are fixedly connected, and two fixed frames 9 are provided. At the same time, the fixed frame 9 near the upper end of the straight plate 1 is fixedly connected to the slider 5, and is fixed by the slide seat 4 and the slider 5 to form an integral body. When in use, the elastic force of the spring column 3 causes the slide seat 4 to slide downward along the vertical direction of the straight plate 1, and the downwardly moving slide seat 4 and the slider 5 drive the fixed frame 9 at the upper end of the displacement straight plate 1 to move downward. The fixed frame 9 at the upper end of the displacement straight plate 1 is moved downward, so that the two fixed frames 9 are close to each other. When measuring the thickness of the cylinder wall, it is only necessary to place the two fixed frames 9 at the two ends of the pipe wall respectively. Through the elastic force, the two fixed frames 9 are close to each other and can be clamped on the end side of the cylinder pipe. After the measurement is completed, the fixed frame 9 at the upper end of the displacement is pulled in the opposite direction to separate the fixed frames 9 and remove the two fixed frames 9. The control process is fast and convenient for measuring a large number of cylinder pipes. When the slide seat 4 is displaced, the header 6 is displaced accordingly. Through the header 6 and the scale mark 8, the displacement parameter is read to obtain the thickness of the cylinder pipe wall.

[0027] Based on the first embodiment, Figure 3 and Figure 4As shown, the solid frame 9 is fixedly connected to the threaded rod 10, and the threaded rod 10 is threadedly connected to the cushion column 11. Two threaded rods 10 and two cushion columns 11 are provided. At the same time, the solid frame 9 near the lower end of the straight plate 1 is fixedly connected to the straight plate 1. By rotating the cushion column 11, the threaded rod 10 and the cushion column 11 are threadedly connected to form a whole. The end wall of the cushion column 11 is used to contact the wall of the cylinder tube for wall thickness measurement. Conversely, the threaded rod 10 and the cushion column 11 are disassembled, the cushion column 11 is removed, and the cushion column 11 is cleaned and washed. Through the slideway 12, the slider 5 is connected to the solid frame 9 located at the upper end of the straight plate 1.

[0028] Working principle: The slide seat 4 and the slider 5 are fixed to form an integral body. When in use, the elastic force of the spring column 3 causes the slide seat 4 to slide down along the vertical direction of the straight plate 1. The downwardly moved slide seat 4 and the slider 5 drive the fixed frame 9 at the upper end of the displacement straight plate 1 to move downward. The fixed frame 9 at the upper end of the displacement straight plate 1 moves downward, and the two fixed frames 9 are brought close to each other. When measuring the thickness of the cylinder wall, it is only necessary to place the two fixed frames 9 on the two ends of the pipe wall respectively. Through the elastic force, the two fixed frames 9 are close to each other and can be clamped on the end side of the cylinder pipe. After the measurement is completed, the fixed frame 9 at the upper end of the displacement is pulled in the opposite direction to separate the fixed frames 9. The two fixed frames 9 are removed and controlled. The process is fast and convenient for measuring a large number of cylinder tubes. When the slide 4 is displaced, the header 6 is displaced accordingly. The displacement parameters are read through the header 6 and the scale mark 8 to obtain the cylinder tube wall thickness. The threaded rod 10 is threadedly connected with the cushion column 11 by rotating the cushion column 11 to form a whole. The end wall of the cushion column 11 is used to contact the cylinder tube wall for wall thickness measurement. Conversely, the threaded rod 10 and the cushion column 11 are separated, the cushion column 11 is removed, and the cushion column 11 is cleaned and washed. Through the slideway 12, it is used to connect the slider 5 and the fixed frame 9 located at the upper end of the straight plate 1 together.
