Description

Technical Field

[0001] This utility model relates to a manual measuring fixture for the straightness and circular runout of a spinning cylinder. Background Technology

[0002] In the manufacturing process of spinning cylinders, reverse spinning is often the preferred method because it effectively controls material flow, reduces internal stress, and improves product surface quality and dimensional accuracy. However, an inherent characteristic of reverse spinning is that, as the spinning process progresses, the tail end of the spinning cylinder often gradually detaches from the mold due to the characteristics of metal flow, resulting in a suspended state. This characteristic undoubtedly increases the difficulty of subsequent processing for products that require strict control of straightness and circular runout. Therefore, it is necessary to control the straightness and circular runout of the spinning cylinder during the spinning stage.

[0003] There are generally two methods for measuring straightness and circular runout. The first method is to use laser interferometers, coordinate measuring machines, etc. to measure straightness and circular runout. These instruments are expensive and complicated to operate, which increases production costs. The second method is to use a testing platform to manually measure the spinning cylinder by placing it on the testing platform. Traditional manual testing platforms require clamping the spinning cylinder at both ends. The clamping process can easily cause deformation of the spinning cylinder, especially thin-walled spinning cylinders, thus affecting the accuracy of the measurement results. Utility Model Content

[0004] The main purpose of this invention is to provide a manual measuring fixture for the straightness and circular runout of a spinning cylinder, so as to solve the problems mentioned in the background art.

[0019] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0020] like Figures 1-6 As shown, the manual measuring fixture for the straightness and circular runout of the spinning cylinder provided in this embodiment includes multiple spaced support seats 1. A plate 2 is provided on the top of the multiple support seats 1. Multiple roller bases 3 are spaced along the length of the plate 2. A fixed roller frame 4 is provided at one end of the roller base 3. A fixed roller 5 is rotatably connected to the fixed roller frame 4. A movable roller frame 6 is provided at the other end of the roller base 3. A movable roller 7 is rotatably connected to the movable roller frame 6. A guide rail 8 is provided on one side of the fixed roller 5 along the length of the plate 2. A first slider 9 is provided on the guide rail 8. A dial indicator 10 is provided on the first slider 9.

[0021] The dial indicator 10 is mounted on the first slider 9 via a magnetic base so as to adjust the position of the measuring head of the dial indicator 10 so that the measuring head can abut against the outer wall of spinning cylinders of different diameters.

[0022] When using it, you need to fix the dial indicator 10 and manually rotate the spinning cylinder to measure the circular runout, or keep the spinning cylinder stationary and manually push the dial indicator 10 to measure the straightness.

[0023] Although manually rotating the spinning cylinder and moving the dial indicator 10 are inferior to machine tool power drives in terms of motion smoothness and speed consistency, and may introduce additional errors, this application uses the plate 2 as a unified reference plane for the entire measurement, ensuring the reference stability of straightness measurement. The adjustable V-shaped support formed by the combination of fixed rollers 5 and moving rollers 7 reliably supports the spinning cylinder while limiting its degree of freedom and abnormal movement during rotation. The guide rail 8 and the first slider 9 restrict the movement path of the dial indicator 10, significantly reducing the adverse effects of manual operation. Comparative tests have verified that its measurement results are almost consistent with the machine tool test results, which can meet the accuracy requirements of on-site testing.

[0024] In this embodiment, as Figure 5 As shown, the support base 1 includes an upper mounting plate 101 and a lower mounting plate 102. A first support frame 103 and a second support frame 104 are arranged in a cross-distribution between the upper mounting plate 101 and the lower mounting plate 102, which enhances the stability and load-bearing capacity of the structure and ensures that the support base 1 is not easily deformed during the measurement process.

[0025] In this embodiment, as Figure 5 As shown, the first support frame 103 and the second support frame 104 are rotatably connected at their middle parts. The lower end of the first support frame 103 is rotatably connected to the lower mounting plate 102, and the upper end of the second support frame 104 is rotatably connected to the upper mounting plate 101. The upper mounting plate 101 is provided with a height adjustment screw 11, and a second slider 12 is threaded onto the height adjustment screw 11. The upper end of the first support frame 103 is rotatably connected to the second slider 12. The lower mounting plate 102 is provided with a slide rail 13, and a third slider 14 is provided inside the slide rail 13. The lower end of the second support frame 104 is rotatably connected to the third slider 14. By rotating the height adjustment screw 11, the second slider 12 and the third slider 14 can move left and right, changing the opening angle of the first support frame 103 and the second support frame 104, thereby adjusting the height of the support seat 1. When encountering uneven ground, the height of each support seat 1 is adjusted to keep the plate 2 level.

[0026] In this embodiment, as Figure 5 As shown, the height adjustment screw 11 is equipped with a height adjustment handwheel 15, and the height adjustment handwheel 15 is equipped with a height adjustment dial. The accuracy of the height adjustment dial is 0.02mm. The height of the support base 1 can be adjusted by rotating the height adjustment handwheel 15. The height adjustment dial provides a precise height adjustment reading, making the operation more accurate and reliable.

[0027] In this embodiment, as Figure 6 As shown, an adjusting screw 16 is provided on the roller base 3, and the movable roller frame 6 is threadedly connected to the adjusting screw 16, allowing the user to adjust the position of the movable roller 7 to accommodate spinning cylinders of different diameters, thus enhancing the adaptability of the measuring fixture.

[0028] In this embodiment, as Figure 6 As shown, the adjusting screw 16 is equipped with an adjusting handwheel 17, which is equipped with an adjusting scale. The adjusting scale has an accuracy of 0.02mm, providing a precise reading for adjusting the roller spacing, making the operation more accurate and reliable.

[0029] In this embodiment, as Figure 2 As shown, a level 18 is installed on the plate 2. The level 18 is magnetically attached to the plate 2. In use, the level 18 is placed on the surface of the plate 2. When the bubble in the level 18 reaches the middle position, the plate 2 is in a horizontal state. A shim can be placed between the plate 2 and the roller base 3 to further adjust the height of both ends of the spinning cylinder, keeping the spinning cylinder horizontal. The level 18 can be removed and placed on the spinning cylinder to check whether the spinning cylinder is in a horizontal state.

[0030] In this embodiment, as Figure 2 As shown, multiple threaded holes 19 are spaced apart along the length of the plate 2. There are two roller bases 3. The two roller bases 3 are fixed to the plate 2 by bolts. By fixing the roller bases 3 to the threaded holes 19 at different positions according to the length of the spinning cylinder, the roller bases 3 can be placed at both ends of the spinning cylinder to ensure stable load bearing.

[0031] In this embodiment, as Figure 1 As shown, there are three support seats 1. The three support seats 1 are located below the plate 2 and are evenly distributed along the length of the plate 2. The three support seats are respectively located at both ends and the middle of the bottom surface of the plate. The support seats 1 at both ends are mainly responsible for adjusting the levelness of the plate 2, while the support seat 1 in the middle mainly serves to assist in supporting the plate 2, bearing the weight of the plate 2, reducing the bending deflection of the plate 2 caused by gravity, and ensuring the flatness of the plate 2.

[0032] In this embodiment, as Figure 1 As shown, the bottom of the support base 1 is equipped with casters 20, which allows the entire measuring fixture to be moved easily, facilitating measurement in different positions and improving ease of use.

[0033] A method for measuring the straightness and circular runout of a spinning cylinder using a manual measuring fixture, comprising the following steps: Step S1: Push the measuring fixture to the appropriate position using the caster wheel 20, and fix the caster wheel 20 to keep the measuring fixture stable; Step S2: Rotate the height adjustment handwheel 15 on the support seat 1 of the measuring fixture to adjust the level of the plate 2 by adjusting the height of each support seat 1. During the adjustment process, observe the level 18 on the plate 2. When the bubble in the level 18 is in the middle position, the plate 2 is in a level state. Step S3: Adjust the distance between the roller bases 3 at both ends of the plate 2 according to the length of the spinning cylinder, so that the two roller bases 3 are respectively located at both ends of the spinning cylinder; Step S4: Rotate the adjusting handwheel 17 on the roller base 3 to adjust the distance between the fixed roller 5 and the movable roller 7 on the roller base 3 according to the outer diameter of the spinning cylinder. Place the spinning cylinder horizontally and stably between the fixed roller 5 and the movable roller 7 on both sides. The two ends of the spinning cylinder should not exceed the two ends of the plate 2. Step S5: When measuring the circular runout of the spinning cylinder, fix the first slider 9 so that the position of the dial indicator 10 on the first slider 9 is fixed. Place the measuring head of the dial indicator 10 against the outer wall of the spinning cylinder, manually hold both ends of the spinning cylinder, continuously rotate the spinning cylinder, and observe the runout on the dial indicator 10. The circular runout of a certain section of the spinning cylinder can then be measured. Step S6: When measuring the straightness of the spinning cylinder, allow the first slider 9 to slide freely on the guide rail 8. Place the measuring head of the dial indicator 10 against the outer wall of the spinning cylinder. Slide the first slider 9 back and forth smoothly on the guide rail 8 and observe the jump on the dial indicator 10. The straightness of the spinning cylinder generatrix at the current angle can be measured. Manually grasp both ends of the spinning cylinder and rotate the spinning cylinder to another angle. Repeat the above operation to measure the straightness of the spinning cylinder generatrix at that angle. Combine the straightness of each spinning cylinder generatrix and take the largest straightness as the final straightness of the spinning cylinder.

[0034] The manual measuring fixture can measure the length of the spinning cylinder from 700mm to 6000mm. The manual measuring fixture can measure the outer diameter of the spinning cylinder from 150mm to 650mm.

[0035] In summary, the measuring fixture provided in this embodiment can adapt to spinning cylinders of different lengths and outer diameters by adjusting the distance between the roller bases 3 and the distance between the fixed rollers 5 and the movable rollers 7. After the spinning cylinder is correctly placed, the straightness and circular runout results can be obtained by manually controlling the spinning cylinder and the dial indicator 10. This optimizes the detection method, simplifies operation, and eliminates the need for complex and expensive detection equipment, effectively reducing detection costs. Especially for thin-walled spinning cylinders, no external force is applied to the spinning cylinder during the measurement process, avoiding the risk of deformation caused by the measurement operation.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
