Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a length measuring device suitable for metal sheets. Background Art

[0002] In some special-purpose tires, such as engineering tires or heavy-duty vehicle tires, metal sheets or other metal components may be used as internal reinforcements to improve the tire's load-bearing capacity and durability. During the metal sheet production process, after the metal sheets are cut into long strips of a certain length, the cut metal sheets need to be measured.

[0003] Currently, due to the different lengths of metal wave plates, a large vernier caliper is required to measure metal sheets. The zero scale of the vernier caliper is aligned with one end of the metal sheet. When the vernier caliper slides along the main scale and contacts the other end of the metal sheet, the difference in scales between the two is used to accurately measure the length.

[0004] When the length of a metal strip needs to be measured, the thin sheet is easy to bend, which will lead to inaccurate length measurement. In addition, a large vernier caliper is long and heavy, time-consuming and labor-intensive to use, and is easily deflected and difficult to operate, resulting in poor measurement accuracy.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-4 The tool is fixed on the upper surface of the workbench 1 and is provided with a plurality of adjusting devices, and the adjusting devices are connected to the tool holder 1 through a plurality of adjusting screws. The adjusting devices are connected to the tool holder 1 through a plurality of adjusting screws. The adjusting devices are connected to the tool holder 1 through a plurality of adjusting screws. The adjusting devices are connected to the tool holder 1 through a plurality of adjusting screws.

[0026] The lifting structure is arranged at one end of the bottom of the placement groove 3 close to the positioning block 4, and is used to lift the metal sheet after measurement to avoid inconvenience in taking out the material.

[0027] In some specific embodiments, such as Figure 4As shown, in order to facilitate adjustment of the angle of the display 8, the adjustment component includes a semicircular ring 15, a U-shaped block 16 and a screw 17. A vertical rod 14 is fixedly provided on the top of the sliding component 5, and a connecting block is fixedly provided on the bottom of the display 8. The connecting block and the vertical rod 14 are rotatably connected through a rotating shaft. The semicircular ring 15 is fixedly provided at the bottom of the display 8 along the width direction of the display 8. A U-shaped block 16 aligned with the semicircular ring 15 is provided on the top of the sliding component 5. The semicircular ring 15 is slidably connected in the groove of the U-shaped block 16. The screw 17 passes through a side wall of the U-shaped block 16 and is threadedly connected to the U-shaped block 16. The end of the screw 17 is supported by the side of the semicircular ring 15. Screwing the screw 17 can fix the semicircular ring 15, and screwing the screw 17 in the opposite direction can release the fixation of the semicircular ring 15.

[0028] In some specific embodiments, such as Figure 2 or Figure 3 As shown, in order to facilitate the removal of the metal sheet after measurement, the lifting structure includes a push plate 12 and a push rod 11. A groove body 10 is provided at the bottom of the placement groove 3. The push plate 12 is vertically slidably connected to the inside of the groove body 10. A push rod 11 is fixedly connected to the bottom of the groove body 10. The push rod 11 passes through the bottom of the placement table 1 and is slidably connected to the placement table 1. When the push rod 11 is pushed upward, the push plate 12 rises accordingly. When the push plate 12 exceeds the bottom of the placement groove 3, the metal sheet placed inside the placement groove 3 can be lifted up for easy removal.

[0029] In some specific embodiments, such as Figure 3 As shown, in order to facilitate the automatic reset function of the push plate 12, a number of springs 13 are elastically connected between the push plate 12 and the trough body 10. One end of the spring 13 is fixedly connected to the bottom of the push plate 12, and the other end is fixedly connected to the inner wall of the trough body 10 close to the push plate 12. When the push rod 11 is pushed, the push plate 12 drives the spring 13 to stretch. After the push rod 11 is released, due to the rebound force of the spring 13, the push plate 12 automatically resets and falls back into the groove of the trough body 10.

[0030] In some specific embodiments, such as Figure 1 or Figure 4 As shown, in order to facilitate enhancing the smoothness of sliding of the sliding component 5, limiting grooves are opened on both sides of the convex strip, and a limiting strip 9 corresponding to the limiting groove is provided on the sliding component 5. The sliding component 5 is slidably connected to the convex strip through the limiting strip 9. A plurality of rollers 18 are distributed on one side of the sliding component 5 close to the top of the convex strip. The rollers 18 are rollingly connected to the convex strip. When the sliding component 5 is pushed to move, the limiting strip 9 is slidably connected to the corresponding limiting groove, and the rollers 18 roll on the convex strip.

[0031] In some specific embodiments, such as Figure 1 As shown, in order to enhance the friction of the bottom of the placement platform 1, anti-slip pads 19 are fixedly connected to both ends of the bottom of the placement platform 1 to prevent the placement platform 1 from slipping and damaging the magnetic scale 6.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0033] During measurement, the sliding component 5 is moved to fit with the positioning block 4 so that the side of the read head 7 is in contact with the side of the positioning block 4. At this time, the number on the display 8 connected to the read head 7 is reset to zero, and then the sliding component 5 is moved to the side away from the positioning block 4. The metal sheet to be measured is placed on the placement slot 3, one end of the metal sheet is flush with the side of the positioning block 4, and then the sliding component 5 drives the read head 7 to approach the other end of the metal sheet so that the sliding component 5 is in contact with the free end of the metal sheet. The inductive head inside the read head 7 scans the magnetic scale 6 and generates a signal. After processing by the signal processing board inside the read head 7, the position information of the magnetic scale 6 can be obtained. The number read on the display screen is the measured length, which can achieve fast measurement, improve the measurement rate, and improve the measurement accuracy.

[0034] During the measurement process, the screw 17 can be rotated to release the support on the semicircular ring 15, and then the display 8 can be rotated to adjust the display surface of the display 8 to a position that is convenient for the staff to observe, so that the staff can conveniently observe the display surface of the display 8 whether sitting or standing, and then the screw 17 can be rotated so that the end of the screw 17 can support the semicircular ring 15 to fix it, thereby achieving a fixed display angle of the display 8.

[0035] After the measurement is completed, since the metal sheet is placed inside the placement slot 3 and the thickness of the metal sheet is small, it is inconvenient to take it out. At this time, use your fingers to push the push rod 11 to move the push plate 12 upward to push the bottom of the metal sheet. Use the other hand to take out the raised end of the metal sheet, which makes it easier to take out the metal sheet and improves the measurement efficiency of the metal sheet. After releasing the push rod 11, the push plate 12 automatically falls back into the slot body 10 due to the rebound force of the spring 13, and does not affect the next measurement of the metal sheet.

[0036] The above describes several embodiments of the present invention in detail, but the present invention is not limited to these embodiments and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
