Description

Technical Field

[0001] This application relates to the field of concentricity testing technology, and in particular to a fiber tube concentricity testing device. Background Technology

[0002] Fiber conduit is a type of tubing made from fiber materials. There are many types of fiber materials, including carbon fiber, glass fiber, ceramic fiber, and asphalt fiber. It performs well in terms of temperature resistance and insulation, and is mainly used for electrical conduit, conveying pipelines, etc.

[0003] During fiber tube processing, the concentricity of the fiber tube needs to be tested. However, existing concentricity testing devices mostly use a single dial indicator for measurement, resulting in a single measurement point, large measurement errors, and the dial indicator adjustment can only be done visually or based on experience, leading to large adjustment errors and affecting the accuracy of the concentricity test. Therefore, to correct the above defects, we propose a fiber tube concentricity testing device. Utility Model Content

[0004] In view of the above problems, this application provides a fiber tube concentricity testing device to solve the problem that most concentricity testing devices use a single dial indicator for measurement, resulting in a single measurement point, large measurement error, and the dial indicator can only be adjusted visually or based on experience, which leads to large adjustment error and affects the accuracy of concentricity testing.

[0005] This application provides a fiber tube concentricity testing device, including a housing: a pair of electric telescopic rods are fixedly connected to the inner wall of the housing; a horizontal block is fixedly connected to the output shaft of the pair of electric telescopic rods; several limiting blocks are sleeved on the horizontal block; a dial indicator is provided below the limiting blocks; a movable opening is provided on the side wall of the housing; an observation block is fixedly connected to the side wall of the horizontal block; the other side of the observation block passes through the movable opening; a pair of positioning blocks are fixedly connected to the side wall of the housing; an adjusting ruler passes through the observation block; the adjusting ruler is fixedly connected to the side wall of the pair of positioning blocks; a connecting mechanism is provided between the limiting blocks and the dial indicator; and a rotating mechanism is provided inside the housing.

[0006] In some embodiments, each of the limiting blocks has an L-shaped block passing through it, and the top of the horizontal block has a plurality of slots that match the L-shaped block.

[0007] In some embodiments, the connecting mechanism includes a pair of fixing blocks, which are fixedly connected to the side wall of the limiting block. A mounting block is provided below the fixing block, which is fixedly connected to the dial indicator. A bolt passes through the mounting block, and a threaded groove matching the bolt is provided at the bottom of the fixing block.

[0009] In some embodiments, the first three-jaw chuck and the second three-jaw chuck are symmetrically arranged about the central axis of the housing.

[0010] In some embodiments, a plurality of the card slots are equidistantly distributed on the top of the horizontal block.

[0011] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0012] 1. By setting up an electric telescopic rod, horizontal block, limit block, and L-shaped block, several dial indicators can be moved to different positions on the fiber tube. Then, the limit block is locked by the L-shaped block, so that multiple dial indicators can measure at the same time, reducing measurement error and improving the accuracy of concentricity measurement of multiple fiber tubes.

[0013] 2. By setting up the electric telescopic rod, horizontal block, limit block, observation block, and adjusting ruler, start the electric telescopic rod. The electric telescopic rod drives the horizontal block to move up and down until the dial indicator is close to the fiber tube. At this time, record the position of the dial indicator based on the relative position of the observation block and the adjusting ruler. This will prevent the subsequent measurement from being affected by the different positions of the dial indicator, thus improving the accuracy of the concentricity measurement.

[0026] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a fiber tube concentricity testing device, including a housing 1. A pair of electric telescopic rods 2 are fixedly connected to the inner wall of the housing 1. A horizontal block 3 is fixedly connected to the output shaft of the pair of electric telescopic rods 2. Several limiting blocks 4 are sleeved on the horizontal block 3. A dial indicator 5 is provided below the limiting block 4. An opening 6 is provided on the side wall of the housing 1. An observation block 7 is fixedly connected to the side wall of the horizontal block 3. The other side of the observation block 7 passes through the opening 6. A pair of positioning blocks 8 are fixedly connected to the side wall of the housing 1. An adjusting ruler 9 passes through the observation block 7. The adjusting ruler 9 is fixedly connected to the side wall of the pair of positioning blocks 8. A connecting mechanism is provided between the limiting blocks 4 and the dial indicator 5. A rotating mechanism is provided inside the housing 1.

[0028] In the technical solution of this application embodiment, the dial indicator 5 can be easily replaced through the connecting mechanism. Each limiting block 4 has an L-shaped block 10 passing through it. The top of the horizontal block 3 is provided with several slots 11 that match the L-shaped block 10. The connecting mechanism includes a pair of fixing blocks 12, which are fixedly connected to the side wall of the limiting block 4. A mounting block 13 is provided below the fixing block 12. The mounting block 13 is fixedly connected to the dial indicator 5. A bolt 14 passes through the mounting block 13. The bottom of the fixing block 12 is provided with a threaded groove that matches the bolt 14.

[0029] In the technical solution of this application embodiment, the fiber tube can be driven to rotate by the rotating mechanism, which facilitates the measurement of the concentricity of the fiber tube. The rotating mechanism includes a motor 15 and a first three-jaw chuck 16. The first three-jaw chuck 16 is movably connected to the inner wall of the box 1 through a rotating shaft. The motor 15 is fixedly connected to the outer wall of the box 1, and the output shaft of the motor 15 passes through the side wall of the box 1 and is fixedly connected to a second three-jaw chuck 17.

[0030] In the technical solution of this application embodiment, the first three-jaw chuck 16 and the second three-jaw chuck 17 are symmetrically arranged to improve the installation stability of the fiber tube. The first three-jaw chuck 16 and the second three-jaw chuck 17 are symmetrically arranged about the central axis of the box body 1, and a number of slots 11 are equidistantly distributed on the top of the horizontal block 3.

[0031] Working principle: In use, the fiber tube is placed between the first three-jaw chuck 16 and the second three-jaw chuck 17, and the fiber tube is fixed by the first three-jaw chuck 16 and the second three-jaw chuck 17. Then, the limit block 4 is moved as needed until several dial indicators 5 are in the correct positions. Then, the L-shaped block 10 is inserted into the slot 11, and then the electric telescopic rod 2 is activated. The electric telescopic rod 2 drives the horizontal block 3 to move up and down until the dial indicator 5 is close to the fiber tube. At this time, the stopping position of the dial indicator 5 is recorded according to the relative position of the observation block 7 and the adjusting ruler 9. Then, the motor is started. 15. Motor 15 drives the first three-jaw chuck 16 and the second three-jaw chuck 17 to rotate. During the rotation of the fiber tube, the swing amplitude of the dial indicator 5 pointer is observed. Then, the first three-jaw chuck 16 and the second three-jaw chuck 17 are turned to remove the fiber tube and continue to measure other fiber tubes, thereby completing the concentricity measurement between multiple fiber tubes. When the dial indicator 5 needs to be replaced, the bolt 14 is unscrewed, the dial indicator 5 is removed, the new dial indicator 5 is placed under the fixing block 12, and the bolt 14 is tightened again, thereby completing the replacement of the dial indicator 5.
