Description

TECHNICAL FIELD

[0001] The utility model relates to copper foil tube core technical field, especially a kind of FRP tube core measuring frame. BACKGROUND

[0002] At present, different specifications of tube cores are used for packaging by various domestic electrolytic copper foil manufacturers, and the tube core serves as a supporting structure, which can be used as a supporting carrier for copper foil in the production and processing of copper foil, such as in the slitting section, to facilitate the winding and unwinding operation of copper foil. It can keep the copper foil neat and compact during winding, avoid loose and disordered situations of copper foil, and ensure the continuity and stability of copper foil. In some links that need to handle, store or transport copper foil, the copper foil tube core can provide internal support for the copper foil to prevent deformation and damage of the copper foil due to its own gravity or external pressure.

[0003] It can also ensure the accuracy of winding and unwinding: the dimensional accuracy and shape accuracy of the copper foil tube core are very important for the winding and unwinding of copper foil. High-precision tube cores can ensure good straightness and roundness of copper foil during winding and unwinding, avoid deviation and wrinkling, and improve the processing quality of copper foil.

[0004] The most important thing is that the tube core can be recycled and reused multiple times, greatly saving the production cost. However, when recycling, some copper foil, gel and concave uneven places may remain on the surface of the tube core, which needs to be polished and polished. After polishing and polishing of the tube core, the surface finish, roundness runout and straightness of the surface need to be measured by instruments. Therefore, a FRP tube core measuring frame is provided. SUMMARY

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art to solve the problems in the background.

[0006] In order to solve the above technical problems, the utility model provides the following technical scheme:

[0007] The utility model discloses a kind of FRP tube core measuring frame, including experiment rack, it is characterized by: two groups of bearing seats are provided at the both ends of the experiment rack, any group of bearing seat is rotatably connected with guide roller, any group of bearing seat is provided with adjusting assembly, the adjusting assembly is used to adjust the level and spacing of the corresponding guide roller, tube core is placed on the upper surface of two guide rollers, the upper surface of the experiment rack is equipped with linear guide rail, the linear guide rail is slidably connected with slide, the upper surface of the slide is magnetically connected with magnetic base, the upper end of the magnetic base is connected with connecting rod, the one end of the connecting rod is provided with dial gauge.

[0008] As a preferred embodiment of the present invention, the adjustment component includes a horizontal adjustment component and a spacing adjustment component.

[0009] As a preferred technical solution of this utility model, the horizontal adjustment component includes two bolts and two set screws. The upper surface of the bearing seat is provided with symmetrical elongated slots and threaded holes on both sides. The upper surface of the experimental frame is provided with two sets of threaded holes. The bolts pass through the corresponding elongated slots and are threadedly connected to the threaded holes. The set screws are threadedly connected to the corresponding threaded holes.

[0010] As a preferred technical solution of this utility model, the spacing adjustment component includes a limiting block and a second set screw. The limiting block is fixedly installed on the test frame. The limiting block is provided with a third threaded hole. The limiting block is threadedly connected to the second set screw through the third threaded hole. One end of the second set screw abuts against one side of the corresponding bearing seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Specifically, during use, the horizontal height, angle, and spacing of the bearing housing are adjusted by adjusting the components. First, the bearing housing is initially positioned by tightening the bolts. Then, the fine-tuning bolts are slowly loosened, allowing the bearing housing to gradually reach a free state. Next, using set screw one, one end of set screw one is pressed against the upper surface of the experimental frame, lifting the bearing housing and adjusting the level of the guide roller. Similarly, since the bearing housing is currently fixed by bolts, its position is not precise enough. At this point, we use set screw two for fine-tuning. By rotating set screw two until it abuts against one side of the bearing housing, the level can be adjusted. After the level of the adjusted guide rollers and the spacing between adjacent guide rollers are matched by the limit bearing seat, the core is placed on the two guide rollers. The dial indicator is moved and the reading is observed by the pointer of the dial indicator touching the surface of the core. The measurement is performed slowly to measure the circular runout and straightness parameters of the core. After the core is polished and ground in the production process, the instrument needs to measure the surface smoothness, circular runout and straightness. Using this device can reduce complicated operation procedures and improve efficiency, and quickly measure whether the core meets the standards after polishing and grinding.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] like Figures 1-2 As shown, this utility model discloses an FRP core measuring frame, including a test frame 1. Two sets of bearing seats 2 are provided at both ends of the test frame 1. A guide roller 3 is rotatably connected to each set of bearing seats 2. An adjustment component is provided on each set of bearing seats 2. The adjustment component is used to adjust the level and spacing of the corresponding guide roller 3. A core 4 is placed on the upper surface of the two guide rollers 3. The core 4 is the part to be tested. A linear guide rail 5 is provided on the upper surface of the test frame 1. A slide block 6 is slidably connected to the linear guide rail 5. The slide block 6 slides on the linear guide rail 5 and can stop at any position. A magnetic base 7 is magnetically connected to the upper surface of the slide block 6. A connecting rod 8 is connected to the upper end of the magnetic base 7. A dial indicator 9 is provided at one end of the connecting rod 8. The dial indicator reading is observed by contacting the surface of the core 4 with the pointer of the dial indicator 9, and the parameters of the core are measured.

[0020] Furthermore, such as Figure 2The adjustment components include a horizontal adjustment component and a spacing adjustment component. The horizontal adjustment component includes two bolts 10 and two set screws 11. The upper surface of the bearing seat 2 has symmetrical elongated slots and threaded holes 1 on both sides. The upper surface of the experimental frame 1 has two sets of threaded holes 2. The bolts 10 pass through the corresponding elongated slots and are threaded into the threaded holes 2. The bearing seat 2 can be adjusted left and right through the elongated slots to control the spacing between the two bearing seats 2. After the spacing is adjusted, it can be tightened by bolts 10. The set screws 11 are threaded into the corresponding threaded holes 1. The set screws 11 can lift the lower surface of the bearing seat 2 and adjust the two sides of the same bearing seat 2 to adjust the horizontal height and angle of the bearing seat 2.

[0021] The spacing adjustment assembly includes a limiting block 12 and a set screw 13. The limiting block 12 is fixedly installed on the test frame 1. The limiting block 12 is provided with a threaded hole 3. The limiting block 12 is threadedly connected to the set screw 13 through the threaded hole 3. One end of the set screw 13 abuts against one side of the corresponding bearing seat 2. Through the design of the set screw 13, the left and right spacing of the bearing seat 2 can be adjusted.

[0022] Specifically, during use, the horizontal height, angle, and spacing of the bearing seat 2 are adjusted by adjusting the components. Specifically, the bearing seat 2 is initially positioned by tightening bolt 10, then the fine-tuning bolt 10 is slowly loosened, allowing the bearing seat 2 to gradually reach a free state. Then, with the help of set screw 11, one end of set screw 11 is pressed against the upper surface of the experimental frame 1, lifting the bearing seat 2 and adjusting the level of the guide roller 3. Similarly, since the bearing seat 2 is currently fixed by bolt 10, its position is not precise enough. At this point, fine-tuning is achieved by rotating set screw 13, which is used to adjust the bearing seat 2. One side of the guide roller 3 is in contact with the other side to limit the bearing seat 2. After the level of the adjusted guide roller 3 and the distance between the guide rollers 3 reach the appropriate value, the core 4 is placed on the two guide rollers 3. The dial indicator 9 is moved and the pointer of the dial indicator 9 contacts the surface of the core 4 to observe the dial indicator reading. During the measurement process, the dial indicator is moved slowly to measure the circular runout and straightness parameters of the core. After the core is polished and ground in the production process, the instrument needs to measure the surface smoothness, circular runout and straightness. Using this device can reduce complicated operation procedures and improve efficiency, and quickly measure whether the core meets the standards after polishing and grinding.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
