Description

Technical Field

[0001] The utility model relates to the technical field of strip winding, in particular to a coil diameter measuring device. Background Art

[0002] During the production process of metal strips, a winder is needed to wind them. During the winding process, not only the winding tension of the strip needs to be controlled, but more importantly, the winding diameter needs to be controlled. In order to measure the winding diameter, there are mainly two methods at present. One is to calculate it through the winding revolutions and the thickness of the strip; the other is to use an ultrasonic or laser diameter gauge for direct detection. The applicant has been engaged in the design and manufacture of aluminum strip production equipment for a long time. The existing aluminum strip winding equipment often uses a diameter gauge for detection and then feeds back to the equipment controller to control the winding diameter. However, when using an ultrasonic or laser diameter gauge, its probe direction needs to be aligned with the axis of the winding shaft along the winding diameter direction. At present, the mounting bracket of the diameter gauge often uses a simple sheet metal bracket, and an arc-shaped long hole is opened on the sheet metal bottom plate for corner adjustment, which is not convenient to adjust and has poor stability.

[0003] Therefore, it is necessary to develop a coil diameter measuring device for the above defects. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a coil diameter measuring device, which uses a support shaft to install the flipping seat, facilitating the corner adjustment of the diameter gauge and having good structural stability at the same time.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] Further, a first tooth surface is provided on the end face of the bottom socket facing the shaft end baffle, and a second tooth surface is provided on the inner end face of the shaft end baffle.

[0009] Further, the tooth patterns of the first tooth surface and the second tooth surface both extend along the diameter direction of the support shaft.

[0010] Further, it further includes a protective cover which is arranged above the main board of the flipping base and encloses the diameter gauge; the protective cover is provided with a relief notch at the front where the diameter gauge probe faces forward.

[0011] Further, side threaded holes are provided on the side wall of the main board of the flipping base, and the bottom edge of the protective cover is installed by screwing into the side threaded holes.

[0027] In a specific embodiment, as Figures 1 to 4 shown, the roll diameter measuring device of the present utility model includes a base frame, a support shaft 3, a flipping seat 4, a diameter gauge 5, and a shaft end baffle 6. The root of the support shaft 3 is fixedly connected to the top of the base frame, and the horizontal cantilever end of the support shaft 3 is inserted into the socket hole of the bottom socket head 401 at the bottom of the flipping seat 4 with a clearance fit. The top of the bottom socket head 401 is welded to the middle position of the bottom surface of the main board of the flipping seat 4. The shaft end baffle 6 is pressed against the end face of the bottom socket head 401 by a fastening screw 7, and the fastening screw 7 is threadedly connected to the middle threaded hole 301 on the cantilever end face of the support shaft 3. The diameter gauge 5 is installed on the top surface of the main board of the flipping seat 4, and the probe of the diameter gauge 5 is inclined upward and faces the winding shaft.

[0028] Specifically, the diameter gauge 5 can be an ultrasonic or laser diameter gauge, which is a purchased part and there are many models on the market, so it will not be elaborated here.

[0029] Specifically, the diameter of the rotary insertion part of the support shaft 3 is not less than 35 mm.

[0030] By using the cantilever support shaft 3 to pick up and flip the flipping seat 4, the relative rotation of the bottom socket head 401 with respect to the support shaft 3 can achieve the adjustment of the orientation angle of the diameter gauge 5, with a large adjustment range and easy to implement; through the setting of the shaft end baffle 6 and the fastening screw 7, it is convenient to quickly lock the position of the flipping seat 4 after adjustment and it is not easy to loosen. The roll diameter measuring device of the present utility model uses a support shaft to install the flipping seat, which is convenient for the angular adjustment of the diameter gauge and has good structural stability.

[0031] In a specific embodiment of the present utility model, as Figure 1 and Figure 2 shown, the base frame includes a base plate 1 and a support arm 2. The bottom of the support arm 2 is installed on the base plate 1 by screws. The support arm 2 is a vertical plate structure, and the base plate 1 is installed on the frame of the winding machine. A mounting hole 201 is horizontally opened at the top of the support arm 2, and the root of the support shaft 3 is inserted into the mounting hole 201 and welded together at the end face.

[0032] By using the support arm 2 to fixedly support the support shaft 3, it is convenient for the flipping seat 4 to achieve flipping within a large angular range without interference.

[0033] In a specific embodiment of the present utility model, as Figure 2 and Figure 3 shown, a first tooth surface 4011 is provided on the end face of the bottom socket head 401 facing the shaft end baffle 6, and a second tooth surface 601 is provided on the inner end face of the shaft end baffle 6. The first tooth surface 4011 and the second tooth surface 601 are engaged to lock the relative position.

[0034] Specifically, as Figure 3As shown, the tooth patterns of the first tooth surface 4011 and the second tooth surface 601 are both oriented along the diameter direction of the support shaft 3 .

[0035] Obviously, the tooth patterns of the first tooth surface 4011 and the second tooth surface 601 can also be concave-convex dot patterns or other forms of anti-slip patterns, which can also play an anti-loosening effect to a certain extent. Similar simple replacement methods all fall within the protection scope of the present utility model.

[0036] By setting tooth surfaces on the end faces of the bottom sleeve 401 and the shaft end baffle 6 that are pressed against each other, the relative positions can be locked by bite during the tightening process to prevent loosening; by setting tooth patterns along the diameter direction, they can be effectively locked in the compressed state to prevent circumferential relative rotation.

[0037] In a specific embodiment of the present invention, Figure 1 and Figure 4 As shown, the roll diameter measuring device of the utility model further includes a shield 8, which is a sheet metal part, and is arranged above the main board of the flip seat 4 and closes the diameter gauge 5. The shield 8 is provided with a clearance slot when the probe of the diameter gauge 5 faces forward, which does not affect the normal operation of the diameter gauge 5.

[0038] Specifically, if Figure 1 and Figure 4 As shown, a side threaded hole 402 is provided on the side wall of the main board of the flip seat 4, and the bottom edge of the shield 8 is installed by screwing the side threaded hole 402. In a specific embodiment, four side threaded holes 402 are symmetrically arranged on two long side walls of the main board of the flip seat 4.

[0039] The caliper 5 is sealed and protected by adding a protective cover 8 to reduce the influence of dust on the caliper 5 of the precision instrument; the protective cover 8 is installed by connecting the side threaded hole 402 with screws, which is easy to disassemble.

[0040] In a specific embodiment of the present invention, Figure 4 As shown, a mounting slot 403 is provided on the top surface of the main board of the flip seat 4, and two mounting slots 403 are provided in parallel along the direction of the probe of the caliper 5. The bottom plate of the caliper 5 is installed in the mounting slot 403 by bolts.

[0041] Specifically, if Figure 4 As shown, the installation slot 403 is specifically a dovetail slot or a T-slot, and a dovetail slider or a T-slide with a threaded hole is embedded in the installation slot 403. The dovetail slider or the T-slide is installed by bolts and threads on the bottom plate of the diameter gauge 5.

[0042] By usually providing a mounting slot 403 on the top surface of the main board of the flip seat 4, it is convenient to move the mounting position of the caliper 5 forward and backward to obtain a better measurement effect. By arranging an embedded dovetail slider or a T-shaped slider, the forward and backward position can be adjusted arbitrarily.

[0043] |Working process of the roll diameter measuring device of the utility model: When installing and debugging the diameter gauge 5, first preliminarily install the diameter gauge 5 on the top surface of the flip seat 4 main board through the T-shaped slider and bolts. Before adjusting the swing angle, use a wrench to loosen the fastening screws 7 without removing them, so that the bottom sleeve 401 can be manually moved to rotate the flip seat 4 relative to the support shaft 3. Turn on the red light debugging light of the diameter gauge 5, observe whether the red light spot falls on the center position of the winding shaft, and rotate the flip seat 4 so that the probe direction is as close to the diameter direction of the winding shaft as possible. After adjustment, gradually tighten the fastening screws 7. Note that the flip seat 4 must not rotate twice during the locking process. Adjust the front and rear positions of the diameter gauge 5 on the mounting slide 403 according to the installation distance requirements of the diameter gauge 5, and retighten the bolts to lock the position after meeting the set requirements. During use, if it is found that the diameter gauge 5 has accidentally deflected or is no longer accurate, it can be readjusted.

[0044] In summary, the roll diameter measuring device of the utility model uses the cantilever support shaft 3 to connect the flip seat 4, and the bottom sleeve 401 can be rotated relative to the support shaft 3 to adjust the direction angle of the diameter gauge 5. The adjustment range is large and easy to implement; through the setting of the shaft end baffle 6 and the fastening screw 7, it is convenient to quickly lock the position of the flip seat 4 after adjustment, and it is not easy to loosen. The roll diameter measuring device of the utility model adopts the support shaft to install the flip seat, which is convenient for adjusting the rotation angle of the diameter gauge and has good structural stability. In addition, the support shaft 3 is fixedly supported by the support arm 2, which is convenient for the flip seat 4 to achieve flipping within a large angle range without interference. By setting the tooth surface on the end face of the bottom sleeve 401 and the shaft end baffle 6 that are pressed against each other, the relative position can be locked by bite during the tightening process to avoid loosening; by setting the tooth pattern along the diameter direction, it can be effectively locked in the compressed state to prevent circumferential relative rotation. The caliper 5 is enclosed and protected by adding a protective cover 8 to reduce the impact of dust on the precision instrument caliper 5; the protective cover 8 is installed by screwing the side threaded hole 402, which is easy to disassemble. By usually providing an installation slide groove 403 on the top surface of the main board of the flip seat 4, it is convenient to move the installation position of the caliper 5 forward and backward to achieve a better measurement effect. By providing an embedded dovetail slider or a T-shaped slider, the forward and backward position can be adjusted arbitrarily.
