Description

Technical Field

[0001] This utility model relates to the field of standardized measuring calipers, specifically to a vernier caliper for standardized measurement of flexible workpieces that can avoid workpiece deformation and thus improve measurement accuracy. Background Technology

[0002] Today, measurement technology has permeated all aspects of production and daily life. Whether in scientific research laboratories or industrial production sites, accurate and reliable measurement data are crucial to ensuring work quality and production safety. However, due to the diversity of measurement equipment and the lack of standardization in measurement methods, problems such as inconsistent data and difficulty in controlling errors often arise. Therefore, standardized measurement data ensures reliable technical information.

[0003] Currently, to ensure standardized and consistent measurement of parameters such as workpiece length, width, and thickness, vernier calipers are typically used to obtain relatively accurate and reliable measurement data. However, when using existing vernier calipers, the workpiece to be measured is clamped between the measuring jaws of the vernier scale and the measuring jaws of the main scale by moving the vernier scale. The two measuring jaws press against the workpiece. Since the movement of the measuring jaws relies entirely on manual operation by the user, when measuring workpieces made of soft or easily deformable materials, manual operation by the user may cause excessive clamping force, resulting in plastic deformation of the workpiece. On the other hand, insufficient force may lead to poor contact, thus introducing system measurement errors and reducing the accuracy of the measurement data. Utility Model Content

[0004] The purpose of this invention is to provide a vernier caliper for standardized measurement of flexible workpieces, so as to solve at least one of the technical problems existing in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a vernier caliper for standardized measurement of flexible workpieces, including a main scale and a vernier scale slidably mounted on the main scale, with a fastening screw on the vernier scale; a clamping plate is provided on one side of the measuring jaw on the vernier scale, which contacts the workpiece to be measured during use; a threaded seat is provided on the side of the clamping plate opposite to the measuring jaw, and a through-hole is provided on the measuring jaw, with the threaded seat slidably extending into the through-hole; an insulating top rod is threadedly connected to the threaded seat and located in the through-hole, with an indicator light assembly detachably connected to the end of the through-hole away from the clamping plate, and a conductive head that can contact the indicator light assembly is provided at the end of the insulating top rod; a limiting ring is fixedly provided in the through-hole, and the insulating top rod can slide through the limiting ring, with an elastic element provided between the limiting ring and the threaded seat.

[0007] Furthermore, the indicator light assembly includes an insulating lamp holder detachably connected to the measuring claw; a storage battery is disposed within the insulating lamp holder; an indicator light is disposed on the insulating lamp holder, one end of the indicator light being electrically connected to the output terminal of the storage battery, and the other end of the indicator light being electrically connected to the input terminal of the storage battery.

[0008] Furthermore, the end of the insulating lamp holder is detachably provided with a lamp holder cover, and the indicator light is disposed on the lamp holder cover.

[0009] Furthermore, the lamp holder cover has a conductive protrusion in the middle that is connected to the battery. The conductive protrusion is connected to one end of the indicator light. A conductive ring is provided on the radial end face of the insulating lamp holder, and the conductive ring is connected to the other end of the indicator light.

[0010] Furthermore, the interior of the insulating lamp holder is provided with a conductive sheet connected to the conductive ring, and one end of the conductive sheet extends into the interior space of the insulating lamp holder.

[0011] Furthermore, one end of the insulating lamp holder is a connector with external threads, and the inner wall of the through-hole is provided with an internal thread that matches the external thread. The connector is threadedly connected to the through-hole.

[0012] Furthermore, the outside of the insulating lamp holder is provided with an annular groove, and the lamp holder cover is fastened to the annular groove by a clamping clamp.

[0013] Furthermore, the main scale has a toothed groove on its side, and the vernier scale has a gear on its side that meshes with the toothed groove.

[0014] Furthermore, the insulating top rod is provided with a slide block that can slide within the through hole.

[0015] Furthermore, the elastic element is a spring.

[0016] The beneficial effects of this utility model are as follows: The movable vernier caliper clamps the workpiece to be measured through the clamping plate and the measuring jaws on the main scale. The workpiece pushes the clamping plate to move so that the conductive head contacts the indicator light assembly. During this process, the elastic element plays a certain buffering role, avoiding hard contact with the workpiece. When the indicator light assembly lights up, it indicates that the workpiece to be measured has made full contact with the clamping plate. At this time, the movement of the vernier caliper can be stopped, the fastening screw can be tightened to fix the vernier caliper, and the reading can be taken. This avoids workpiece deformation caused by excessive clamping force, improves measurement accuracy, and also protects the workpiece to be measured.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0032] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings, provides further explanation of specific embodiments. These specific embodiments do not constitute a limitation on the embodiments of this utility model.

[0033] Those skilled in the art should understand that the accompanying drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily essential for implementing this utility model.

[0034] like Figures 1 to 4 As shown in this embodiment, a vernier caliper for standardized measurement of flexible workpieces is provided, including a main scale 1 and a vernier scale 2 slidably disposed on the main scale 1. The vernier scale 2 is provided with a fastening screw 3. A clamping plate 5 is provided on one side of the measuring jaw 4 on the vernier scale 2. In use, the clamping plate 5 contacts the workpiece to be measured. The clamping plate 5 is movably disposed on the measuring jaw 4 and can reciprocate in a direction perpendicular to the contact surface of the workpiece to be measured.

[0035] Specifically, to enable the reciprocating movement of the clamping plate 5, a threaded seat 6 is provided on the side of the clamping plate 5 opposite to the measuring claw 4. The measuring claw 4 has a through-hole 7. The threaded seat 6 can slide into the through-hole 7 to achieve the connection between the clamping plate 5 and the measuring claw. The threaded seat 6 has an internal thread, and a movable insulating rod 8 is provided in the through-hole 7. The end of the insulating rod 8 has an external thread. The threaded connection between the threaded seat 6 and the insulating rod 8 is achieved through the cooperation of the internal and external threads. A limiting ring 10 is fixedly provided in the through-hole 7, and the outer surface of the limiting ring 10 is fixedly connected to the inner wall of the through-hole 7. A through hole is provided in the middle of the limiting ring 10. The insulating top rod 8 can slide through the limiting ring 10 through the through hole. An elastic element 11 is provided between the limiting ring 10 and the threaded seat 6. When the clamping plate 5 is squeezed, the threaded seat moves inward along the inner wall of the through sliding hole 7, squeezing the elastic element 11 to compress. When the clamping plate 5 is not in contact with the workpiece to be measured, the elastic element 11 returns to its original state and pushes the clamping plate outward.

[0036] Specifically, the elastic element 11 can be a spring sleeved on the insulating top rod 8. During use, the clamping plate 5 is pressed by the workpiece to be measured. To prevent the flexible workpiece from deforming due to excessive pressure, an indicator light assembly 26 is detachably connected to the end of the through-hole 7 away from the clamping plate 5. The end of the insulating top rod 8 is provided with a conductive head 9 that can contact the indicator light assembly 26. When the clamping plate 5 is pressed and pushes the insulating top rod 8 to move, when the conductive head 9 contacts the indicator light assembly 26, the circuit of the indicator light assembly 26 is connected, and the indicator light lights up. At this time, the movement of the vernier scale can be stopped to avoid deformation of the workpiece due to excessive clamping force, which would affect the measurement accuracy.

[0037] In one specific embodiment, in order to enable the insulating top rod 8 to move linearly and reliably within the through-hole, a slide block 22 that can slide along the inner wall of the through-hole 7 can also be provided on the insulating top rod 8.

[0038] Specifically, in combination Figure 2 As shown, the indicator light assembly includes an insulating lamp holder 12 detachably connected to the measuring claw 4; specifically, one end of the insulating lamp holder 12 is a connector 17 with external threads, and the inner wall of the through-hole 7 is provided with an internal thread that matches the external thread. The connector 17 and the through-hole 7 are detachably connected by the engagement of the external and internal threads. Figure 2 As shown, the insulating lamp holder 12 contains a storage battery, which can be specifically installed in a battery box 23 at the end of the insulating lamp holder 12. The left side of the battery box 23 can be provided with a conductive part that can contact the conductive head 9. This conductive part is connected to the input terminal (negative terminal) of the storage battery inside the battery box 23. The insulating lamp holder is provided with an indicator light 13. One end of the indicator light 13 is electrically connected to the output terminal (positive terminal) of the storage battery. When the conductive head 9 moves to just contact the conductive part on the left side of the battery box 23, the conductive head 9 just connects the circuit of the indicator light, so that the other end of the indicator light 13 is indirectly electrically connected to the input terminal (negative terminal) of the storage battery. The circuit is connected, and the indicator light lights up.

[0039] Specifically, the end of the insulating lamp holder 12 is detachably provided with a lamp holder cover 14, and the indicator light 13 is disposed on the lamp holder cover 14. The lamp holder cover 14 has a conductive protrusion in the middle that connects to the battery. One side of this conductive protrusion is connected to the battery in the battery box 23, and the other side of the conductive protrusion is connected to one end of the indicator light 13. That is, the other side of the conductive protrusion can be adhered to the lamp holder cover 14 and connected to the lead of the indicator light. A conductive ring 15 is provided on the radial end face of the insulating lamp holder 12. The conductive ring 15 is connected to the other end of the indicator light 13, that is, the conductive ring 15 is connected to another lead of the indicator light. Inside the insulating lamp holder 12 is a conductive plate 16 connected to the conductive ring 15. One end of the conductive plate 16 extends into the internal space of the insulating lamp holder 12. When the conductive head just contacts the conductive part on the left side of the battery box 23, it also just contacts the conductive plate 16, thereby achieving circuit continuity and illuminating the indicator light.

[0040] In one specific embodiment, to allow the lamp holder cover 14 to be mounted on the insulating lamp holder 12, an annular groove 18 is provided on the outside of the insulating lamp holder 12, and the lamp holder cover 14 is secured to the annular groove 18 by a clamping clamp 19. When the battery needs to be replaced, the clamping clamp 19 can be removed to remove the lamp holder cover 14, the old battery can be directly removed, a new battery can be installed, and then the lamp holder cover 14 can be put back on and secured with the clamping clamp 19. Due to prolonged use, the elastic element 11 may deform, requiring replacement. When the elastic element 11 needs to be replaced, the entire insulating lamp holder 12 can be removed from the through sliding hole, and then the insulating top rod can be turned to disengage from the threaded seat. The clamping plate can then be removed, and the elastic element 11 can be replaced.

[0041] In one specific embodiment, combined with Figure 3 , Figure 4 As shown, to enable further fine-tuning of the vernier caliper, even if the indicator light is on, excessive clamping force may still cause slight deformation of the workpiece being measured. The user can further fine-tune the vernier caliper until the clamping plate just touches the workpiece, thus ensuring the accuracy of the measurement data. Specifically, to achieve further fine-tuning of the vernier caliper, the main scale 1 has a toothed groove 20 on its side, and the vernier caliper 2 has a rotatable gear 21 that meshes with the toothed groove 20 on its side. By rotating the gear 21, the vernier caliper 2 moves linearly in conjunction with the toothed groove 20. Specifically, a receiving hole for accommodating the gear 21 can be provided on the side of the vernier caliper, and a rotating shaft 24 connected to the gear can also be rotatably provided on the side of the vernier caliper. A knob 25 is provided at the outer end of the rotating shaft 24, allowing the user to rotate the gear 21 via the rotating shaft 24 using the knob 25.

[0042] The vernier caliper for standardized measurement of flexible workpieces described in this embodiment is used as follows: First, the vernier scale is moved to its farthest position until the indicator light illuminates. At this point, the clamping plate contacts the measuring jaws on the main scale. The corresponding positions of the scales on the vernier scale and the main scale are then determined. Next, the vernier scale is moved to separate the clamping plate from the measuring jaws on the main scale. The workpiece to be measured is placed between the clamping plate and the measuring jaws on the main scale. The vernier scale is then moved again until the clamping plate contacts the workpiece. When the indicator light illuminates, the movement of the vernier scale is stopped, and the reading is taken. During this process, the elastic element acts as a buffer, preventing excessive rigid contact between the clamping plate and the workpiece, avoiding deformation of the flexible workpiece, and improving the accuracy of the measurement data.

[0043] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that, based on the technical solutions disclosed in the present utility model, all modifications or variations that can be made by those skilled in the art without creative effort should be included within the scope of protection of the present utility model.
