Description

Technical Field

[0001] This utility model relates to the field of automotive product testing technology, specifically a dial indicator positioning mechanism for rapid testing. Background Technology

[0002] A dial indicator, also known as a pointer-type dial indicator or clock face indicator, is a commonly used precision measuring tool. It is primarily used to measure dimensional deviations and geometric tolerances (such as flatness, roundness, coaxiality, and runout) of workpieces, as well as to monitor minute displacements during mechanical assembly and inspection. Its principle is that when the probe is subjected to an external force and undergoes a minute movement, an internal gear or lever transmission system drives the pointer on the dial to rotate, thus displaying the displacement on the scale. With the rapid development of China's automotive inspection tooling industry and fierce competition, measuring the measurement points of products is an essential process in the manufacturing process. Dial indicators are used when inspecting automotive hoods, door panel trims, glass, and headlights. Because the dimensional tolerance requirements for automotive hoods, door panel trims, glass, and headlights are high, measurements are taken at individual, critical measurement points. Furthermore, since these products require matching the appearance to the vehicle body, a rapid detection positioning mechanism is designed at these critical points, thus increasing measurement accuracy, efficiency, and overall precision.

[0003] When performing dial indicator tests on automotive products, the dial indicator rod is usually fixed to the mounting base by directly tightening bolts. However, this method requires repeated tightening and loosening of the bolts with tools each time the dial indicator is installed, which is cumbersome and not conducive to frequent replacement or quick adjustment of the dial indicator, making the test inconvenient. Therefore, to solve the above problems, a dial indicator positioning mechanism for rapid testing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a dial indicator positioning mechanism for rapid testing, so as to solve the problem mentioned in the background art that the bolt tightening method requires the use of tools to repeatedly tighten or loosen the bolts each time they are assembled and disassembled, which makes the operation cumbersome and is not conducive to frequent replacement or rapid adjustment of the dial indicator, thus making the testing inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dial indicator positioning mechanism for rapid detection, comprising a detection table, a support frame on the surface of the detection table, a mold platform on the surface of the support frame, a base mounted on the surface of the mold platform, and a mounting seat on the surface of the base. A dial indicator is mounted on the inner side of the mounting seat, the base and the mounting seat are magnetically connected, a dial indicator rod is fixedly connected to the bottom end of the dial indicator, a measuring rod is provided on the inner side of the dial indicator, and a glass cover is fixedly connected to the surface of the dial indicator.

[0006] The surface of the mounting base is provided with an assembly mechanism, and the surface of the dial indicator is provided with a protective mechanism;

[0007] The assembly mechanism includes a movable rod that moves within the mounting base, and a clamping block is fixedly connected to the surface of the movable rod. The dial rod, the movable rod, and the clamping block all move within the mounting base.

[0008] The protective mechanism includes a transparent protective cover, which is disposed on the surface of the dial gauge.

[0009] Preferably, the assembly mechanism further includes a first movable groove, which is formed inside the mounting base, and the movable rod moves inside the first movable groove. A first spring is fixedly connected to the surface of the clamping block, and one end of the first spring is fixedly connected to the first movable groove, and the other end of the first spring is fixedly connected to the clamping block.

[0010] Preferably, a fixing block is fixedly connected to the surface of the mounting base, and a limiting rod is movably connected to the inner side of the fixing block. A slot is provided on the inner side of the movable rod, and a second spring is fixedly connected to the surface of the limiting rod.

[0011] Preferably, one end of the second spring is fixedly connected to the limiting rod, and the other end of the second spring is fixedly connected to the fixing block.

[0012] Preferably, the protective mechanism further includes a positioning block, which is fixedly connected to the surface of the transparent protective cover, and a connecting block is fixedly connected to the surface of the dial indicator. The positioning block and the connecting block are arranged in three groups and fixed to the transparent protective cover and the dial indicator respectively.

[0013] Preferably, the positioning block is movable inside the connecting block, and a second movable groove is provided on the inner side of the connecting block, with a third spring fixedly connected to the inner wall of the second movable groove.

[0014] Preferably, a locking block is fixedly connected to the end of the third spring away from the second movable groove, and the locking block moves inside the second movable groove, and a locking groove is opened on the inner side of the positioning block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The movement of the movable rod within the first movable slot, combined with the elasticity of the first spring, allows the clamping block to quickly clamp and release the dial indicator rod. This facilitates the rapid assembly and disassembly of the dial indicator, as well as its replacement and adjustment, making testing more convenient and efficient. Simultaneously, the movement of the limiting rod, in conjunction with the second spring, enables the insertion and separation of the limiting rod and the slot, thus limiting the movement of the movable rod and preventing the clamping block from shifting. This ensures a more stable installation of the dial indicator and better guarantees testing results and quality.

[0017] 2. The transparent protective cover protects the glass cover of the dial indicator, preventing direct exposure and reducing scratches or wear caused by external contact. This extends the overall lifespan of the dial indicator. The positioning and connecting blocks, along with the locking and slotting mechanisms, allow for the secure fixing and separation of the transparent protective cover and the dial indicator. This facilitates the installation, use, and removal of the protective cover, and makes it easy to replace if damaged, ensuring both the usability of the dial indicator and the protection of the glass cover.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 One embodiment provided by this utility model:

[0030] A dial indicator positioning mechanism for rapid testing includes a testing table 1, a support frame 11 on the surface of the testing table 1, a mold platform 12 on the surface of the support frame 11, a base 13 mounted on the surface of the mold platform 12, and a mounting seat 14 on the surface of the base 13. A dial indicator 15 is mounted on the inner side of the mounting seat 14. The base 13 and the mounting seat 14 are magnetically connected. A dial indicator rod 16 is fixedly connected to the bottom end of the dial indicator 15, and a measuring rod 17 is provided on the inner side of the dial indicator 15. A glass cover 18 is fixedly connected to the surface of the dial indicator 15. An assembly mechanism is provided on the surface of the mounting seat 14. The dial indicator 15... The dial indicator 15 is equipped with a protective mechanism. The assembly mechanism includes a movable rod 21, which is movable inside the mounting base 14. A clamping block 22 is fixedly connected to the surface of the movable rod 21. The dial indicator rod 16, the movable rod 21, and the clamping block 22 are all movable inside the mounting base 14. The protective mechanism includes a transparent protective cover 3, which is set on the surface of the dial indicator 15. The automotive product can be placed by setting the mold table 12. Through the cooperation of the base 13 and the mounting base 14, the dial indicator 15 can be quickly installed at the corresponding point, achieving the effect of positioning and installation, thus making the test more convenient.

[0031] Furthermore, the assembly mechanism also includes a first movable groove 2, which is located inside the mounting base 14. The movable rod 21 moves inside the first movable groove 2. A first spring 23 is fixedly connected to the surface of the clamping block 22. One end of the first spring 23 is fixedly connected to the first movable groove 2, and the other end of the first spring 23 is fixedly connected to the clamping block 22. Through the elastic properties of the first spring 23, the clamping block 22 can be reset, thereby enabling the clamping block 22 to clamp the dial indicator rod 16, which facilitates the installation and quick disassembly of the dial indicator 15 and makes testing convenient.

[0032] Furthermore, a fixing block 24 is fixedly connected to the surface of the mounting base 14, and a limiting rod 25 is movably connected to the inner side of the fixing block 24. A slot 26 is opened on the inner side of the movable rod 21, and a second spring 27 is fixedly connected to the surface of the limiting rod 25. By opening the slot 26, the limiting rod 25 and the slot 26 are inserted into each other, which can limit the movable rod 21 and prevent the movable rod 21 from moving, thus affecting the stability of the clamping block 22 clamping the dial indicator 16. As a result, the dial indicator 15 is installed more stably on the mounting base 14 and can be better tested.

[0033] Furthermore, one end of the second spring 27 is fixedly connected to the limiting rod 25, and the other end of the second spring 27 is fixedly connected to the fixing block 24. By setting the second spring 27, the limiting rod 25 can be reset, thereby enabling the limiting rod 25 to be inserted into the slot 26 and limiting the movable rod 21.

[0034] Furthermore, the protective mechanism also includes a positioning block 31, which is fixedly connected to the surface of the transparent protective cover 3. A connecting block 32 is fixedly connected to the surface of the dial indicator 15. The positioning block 31 and the connecting block 32 are in three groups and are respectively fixed to the transparent protective cover 3 and the dial indicator 15. Through the cooperation of the positioning block 31 and the connecting block 32, the transparent protective cover 3 can be positioned on the dial indicator 15, which facilitates the installation and use of the transparent protective cover 3.

[0035] Furthermore, the positioning block 31 is movable inside the connecting block 32, and the inner side of the connecting block 32 is provided with a second movable groove 33. The inner wall of the second movable groove 33 is fixedly connected with a third spring 34. Through the setting of the third spring 34, the elastic property of the third spring 34 can realize the reset of the locking block 35, thereby facilitating the engagement of the locking block 35 and the locking groove 36, and realizing the locking of the positioning block 31 and the connecting block 32. This facilitates the use of the transparent protective cover 3, thereby achieving the effect of protecting the glass cover 18 through the transparent protective cover 3.

[0036] Furthermore, a locking block 35 is fixedly connected to one end of the third spring 34 away from the second movable groove 33, and the locking block 35 moves inside the second movable groove 33. A slot 36 is provided on the inner side of the positioning block 31. Through the movable setting of the locking block 35, the locking block 35 can move and the slot 36 can engage and disengage, which facilitates the use and removal of the transparent protective cover 3, and thus facilitates the replacement of the transparent protective cover 3.

[0037] Working principle: In use, pull the limiting rod 25 to move inside the fixed block 24 and separate it from the slot 26, thereby releasing the limitation on the movable rod 21. At this time, the second spring 27 is in a contracted state. Then pull the movable rod 21 to move inside the first movable groove 2 and drive the clamping block 22 to move. At this time, the first spring 23 is in a contracted state. Then place the dial indicator 15 on the mounting base 14 so that the indicator rod 16 is inserted into the inside of the mounting base 14. Then release the movable rod 21 to reset the clamping block 22 under the rebound action of the first spring 23, thereby clamping the indicator rod 16 with the clamping block 22. This allows the dial indicator 15 to be installed and fixed on the mounting base 14. Finally, release the limiting rod 25 to reset the limiting rod 25 under the rebound action of the second spring 27, thereby allowing the limiting rod 25 to be inserted into the slot 26, thus limiting the movable rod 21 and ensuring that the clamping block 22 stably clamps the dial indicator 15.

[0038] The transparent protective cover 3 protects the glass cover 18, preventing it from directly contacting the outside. When using the transparent protective cover 3, place it on the surface of the dial indicator 15 and insert the positioning block 31 into the inside of the connecting block 32. When the positioning block 31 enters and contacts the locking block 35, the locking block 35 is squeezed and moves into the inside of the second movable groove 33. At this time, the third spring 34 is in a contracted state. When the positioning block 31 is inserted and the locking groove 36 and the locking block 35 are aligned, the locking block 35 is reset under the rebound action of the third spring 34, thus achieving the engagement of the locking block 35 and the locking groove 36, thereby fixing the transparent protective cover 3 on the dial indicator 15. When it is necessary to remove or replace the transparent protective cover 3, pull the transparent protective cover 3 to make the locking block 35 move under force and separate from the locking groove 36, thus separating the positioning block 31 and the connecting block 32.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
