Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] In the existing technology, the gauge blocks customized by the production department are a single structure. A single gauge block can only be used to measure workpieces of a specific size. When producing products of multiple specifications, multiple gauge blocks of different sizes and types need to be customized, resulting in high quality inspection costs and inconvenience for measurement personnel to carry and use.

[0033] In view of the above-mentioned problems in the prior art, this utility model provides a multifunctional measuring block, such as... Figure 1 As shown, the multifunctional measuring block includes: a base 100, a first mounting base 110 fixedly mounted at one end of the base 100, and a second mounting base 120 slidably mounted at the other end of the base 100. A laser rangefinder sensor 200 is mounted on the bottom of the second mounting base 120 at a position corresponding to the position inside the base 100; a first measuring block 310, which is detachably mounted on the first mounting base 110, and several first measuring blocks 310 are provided, with different measurement parameters for the several first measuring blocks 310; and a second measuring block 320, which is detachably mounted on the second mounting base 120, and several second measuring blocks 320 are provided, with different measurement parameters for the several second measuring blocks 320.

[0034] This invention features a fixed first mounting base 110 and a sliding second mounting base 120 on a base 100, with a first gauge block 310 and a second gauge block 320 mounted on them respectively. During use, the distance can be adjusted by the laser range sensor 200 at the bottom of the second mounting base 120. This allows a single measuring block to be adjusted to detect various products according to usage requirements. Furthermore, the first gauge block 310 and the second gauge block 320 with different measurement parameters can be replaced, significantly reducing testing costs while making it convenient for testing personnel to carry and use.

[0035] In the above embodiments, such as Figure 1As shown, the main body of this utility model's multifunctional measuring block consists of a base 100, a first measuring block 310, and a second measuring block 320. A first mounting base 110 is provided at one end of the base 100, and is fixedly positioned at the end of the base 100. In actual manufacturing, it can be integrally formed with the base 100 to simplify the production and installation process. A second mounting base 120 is slidably disposed on the other end of the base 100, with the sliding direction along the length of the base 100. During the sliding process, the orthographic projection of the second mounting base 120 always corresponds to the orthographic projection of the first mounting base 110. The first measuring block 310 is mounted on the first mounting base 110, and the second measuring block 320 is mounted on the second mounting base 120. The structural state of the first measuring block 310 and the second measuring block 320 after installation is as follows. Figure 2 As shown, similar to the gauge block structure in the prior art, it can be used to quickly measure products during the production process to verify whether the dimensions meet the standards.

[0036] Unlike existing technologies, the multifunctional measuring block of this invention features a sliding second mounting base 120. This allows for adjustment of the distance between the first gauge block 310 and the second gauge block 320 according to actual usage needs, enabling proactive changes in the standard measurement spacing. This adapts to the measurement requirements of products of various sizes, eliminating the need for operators to carry numerous gauge blocks of different types. Furthermore, in this embodiment, multiple first gauge blocks 310 and second gauge blocks 320 are actually provided, each with different measurement parameters. This allows users to combine different first gauge blocks 310 and second gauge blocks 320 according to different testing requirements, achieving a multifunctional measurement effect.

[0037] Meanwhile, to ensure accurate adjustment of the distance between the first gauge block 310 and the second gauge block 320, in this embodiment, a laser range sensor 200 is also provided at the bottom of the second mounting base 120, corresponding to the position inside the base 100. The laser range sensor 200 detects the relative distance between itself and the position below the first mounting base 110 using laser detection, thereby achieving precise adjustment when the user actively adjusts the relative position between the second mounting base 120 and the first mounting base 110.

[0038] In another embodiment of this utility model, in order to provide users with real-time feedback from the laser rangefinder 200, a digital display screen 140 is also fitted into one side of the base 100. The digital display screen 140 provides feedback on the measurement data acquired by the laser rangefinder 200 through digital display, so that users can understand the relative distance between the first mounting base 110 and the second mounting base 120 in real time, so as to make precise adjustments before measurement.

[0039] In this embodiment, the digital display screen 140 is connected to the laser rangefinder 200 via a circuit. The circuit structure is arranged inside the cavity of the base 100. Because the laser rangefinder 200 is located inside the cavity of the base 100, the ranging process is not affected by external interference, achieving accurate measurement and replacing the function of existing gauge blocks. Furthermore, this embodiment also includes a communication device in the digital display screen 140. This communication device can specifically use Bluetooth, a local wireless network, or other methods to connect to the user's personal terminal. This arrangement allows the user to check the working status of the laser rangefinder 200 through their personal terminal and record data from the adjustment process, facilitating accurate reporting based on the data records and significantly reducing the user's workload.

[0040] In this embodiment, a storage battery is also installed inside the base 100. The storage battery is connected to the digital display screen 140 and the laser rangefinder 200 via circuitry, thereby providing power to the aforementioned functional components. In this embodiment, the base 100 should also be provided with a power supply interface connected to the storage battery to replenish its power, and a switch structure for controlling the storage battery should be provided to maintain its charge level. Furthermore, when the storage battery is actually installed, it should be fixedly installed inside one end of the base 100. This arrangement avoids interference with the movement path of the second mounting base 120 and also facilitates the arrangement of the charging structure.

[0041] In another possible embodiment of this utility model, such as Figure 1 and Figure 2As shown, the cross-sectional shape of the first mounting base 110 should be the same as the cross-sectional shape of the bottom of the first gauge block 310, and the cross-sectional shape of the second mounting base 120 should be the same as the cross-sectional shape of the bottom of the second gauge block 320. The advantage of this setting is that it can ensure that the distance between each part of the first gauge block 310 and the second gauge block 320 is uniform, thereby avoiding errors in the measurement process. Furthermore, to ensure the measurement accuracy of the laser rangefinder 200, the position inside the base 100 corresponding to the first mounting base 110 is enclosed, and the laser rangefinder 200 is positioned on the second mounting base 120 at the corresponding position facing the first mounting base 110. When the laser rangefinder 200 is turned on, the emitted laser shines on the enclosed position inside the base 100 corresponding to the first mounting base 110, which is equivalent to the laser shining from the side of the second mounting base 120 facing the first mounting base 110 to the side of the first mounting base 110 facing the second mounting base 120. Therefore, it can accurately feedback the distance between the first mounting base 110 and the second mounting base 120. At the same time, since the first gauge block 310 is installed on the first mounting base 110 with the same cross-section, and the second gauge block 320 is installed on the second mounting base 120 with the same cross-sectional shape, the detection distance of the laser rangefinder 200 is equivalent to the relative distance between the first gauge block 310 and the second gauge block 320, which can achieve accurate adjustment.

[0042] In another possible embodiment of this utility model, such as Figure 1 As shown, since both the first gauge block 310 and the second gauge block 320 are detachable, and both the first gauge block 310 and the second gauge block 320 are provided with multiple different measurement parameters, this application also restricts the installation method of the first gauge block 310 and the second gauge block 320 to ensure that the installation process of the first gauge block 310 and the second gauge block 320 will not produce errors that affect the measurement data.

[0043] Specifically, a plurality of slots 130 are respectively provided on the upper side of the first mounting base 110 and the second mounting base 120, and the plurality of slots 130 are arranged along the width direction of the base 100; correspondingly, a plurality of tenons 330 are respectively provided at the lower end of the first gauge block 310 and the second gauge block 320, and the plurality of tenons 330 correspond one-to-one with the plurality of slots 130 and slide to fit together; the aforementioned slots 130 and tenons 330 structures are manufactured by precision casting, CNC and other methods, so that the tenons 330 and slots 130 produce negligible error dimensions during installation. At the same time, since the mating structure of multiple tenons 330 and slots 130 further averages the error value, and the installation direction is along the width direction of the base 100, the installation error of the first gauge block 310 and the second gauge block 320 can be effectively reduced by controlling the above-mentioned factors, ensuring the accuracy of subsequent measurements.

[0044] More specifically, to prevent the first gauge block 310 and the second gauge block 320 from sliding or falling off due to factors such as the placement angle and movement of the multi-functional measuring block during use, this embodiment further restricts the mating structure of the aforementioned tenon 330 and slot 130. Specifically, one end of several slots 130 on the first mounting base 110 is provided to pass through one side of the first mounting base 110, and the other end of the slot 130 is closed to the other side of the first mounting base 110. At the same time, the length of the tenon 330 on the first gauge block 310 is correspondingly set, thereby sealing the slot 130. The closed end can limit the lateral position of the first gauge block 310, thereby preventing the first gauge block 310 from falling off during use. Correspondingly, one end of a plurality of slots 130 on the second mounting base 120 is provided through one side of the second mounting base 120, and the other end of the slot 130 is closed on the other side of the second mounting base 120. At the same time, the length of the tenon 330 on the second gauge block 320 is set accordingly, so that the closed end of the slot 130 can limit the lateral position of the second gauge block 320, thereby preventing the second gauge block 320 from falling off during use.

[0045] It should be noted that the through ends of the slots 130 on the first mounting base 110 and the second mounting base 120 should be respectively set on one side in order to achieve the effect of preventing detachment when used together.

[0046] On the other hand, such as Figure 2 As shown, the side of the base 100 and the corresponding sides of the first mounting base 110, the second mounting base 120, the first gauge block 310, and the second gauge block 320 should be located in the same plane. The advantage of this arrangement is that when the multi-functional measuring block is placed on the side of the workpiece to be inspected or on a structure such as a lathe, it can fit closely with the measuring part to avoid measurement errors caused by line of sight. At the same time, another advantage of this arrangement is that it makes it easier for users to judge whether the first gauge block 310 and the second gauge block 320 are installed in place, and it is convenient to judge the status of the multi-functional measuring block in real time during actual use.

[0047] In the above embodiments, this application provides a plurality of first gauge blocks 310 and second gauge blocks 320, and the measurement parameters of different first gauge blocks 310 and second gauge blocks 320 are different. In this embodiment, the measurement parameters mainly refer to the taper difference of the taper measurement surface 340. Specifically, such as... Figure 1 and Figure 2As shown, a taper measuring surface 340 is provided on the opposite side of the first gauge block 310 and the second gauge block 320. The taper measuring surface 340 is recessed into the first gauge block 310 and the second gauge block 320 along a predetermined arc. This allows the multi-functional gauge block to measure the product standard degree through the relative distance between the first gauge block 310 and the second gauge block 320, while also detecting the taper standard condition of the product through the taper measuring surface 340, thus achieving the effect of multi-functional use.

[0048] In specific settings, the taper of the taper measuring surface 340 includes different tapers such as 1:8, 1:10, and 1:16, for measuring different products. In actual use, users can use the first gauge block 310 and the second gauge block 320 with different taper measuring surfaces 340 together. For example, if the taper of the first gauge block 310 taper measuring surface 340 is 1:8 and the taper of the second gauge block 320 taper measuring surface 340 is 1:16, then in actual use, the distance between the first gauge block 310 and the second gauge block 320 can be compared with the standard length of the product, and the taper condition of different parts of the product can be measured by the taper measuring surfaces 340 on the first gauge block 310 and the second gauge block 320 respectively.

[0049] In another possible embodiment of this utility model, such as Figure 1 As shown, to achieve the effect of stable sliding of the second mounting base 120 on the base 100, in this embodiment, the second mounting base 120 further includes a limiting plate 121. A sliding tenon 122 structure is provided on one side of the limiting plate 121 corresponding to the second mounting base 120. Correspondingly, an adjusting groove 150 is provided on the base 100 along the length direction of the base 100. The width of the adjusting groove 150 matches the width of the sliding tenon 122, and their thicknesses are the same. During actual installation, the sliding tenon 122 is fitted into the adjusting groove 150, the limiting plate 121 is located in the cavity of the base 100 and abuts against the lower side plate of the adjusting groove 150, and the upper end of the sliding tenon 122 is fixedly connected to the second mounting seat 120, forming a clamping structure in which the lower end of the second mounting seat 120 abuts against the upper side plate of the adjusting groove 150. This prevents the second mounting seat 120 from falling off while allowing the sliding tenon 122 to slide along the adjusting groove 150 to achieve the position adjustment effect of the second gauge block 320.

[0050] In this embodiment, the limiting plate 121, the sliding tenon 122, and the second mounting base 120 should be integrally formed. Figure 1The diagram is for ease of understanding only. In addition, the laser rangefinder 200 is set on the side of the limiting plate 121 away from the sliding tenon 122, that is, the laser rangefinder 200 is located inside the cavity of the base 100, so as to achieve the effect of measuring distance corresponding to the closed part of the first mounting seat 110 inside the base 100.

[0051] In this embodiment, to facilitate the fixing of the adjustable position between the first mounting base 110 and the second mounting base 120, it is preferable to use a damped connection between the sliding tenon 122 and the adjusting groove 150. Damping refers to the resistance force experienced by an object during movement due to friction or attraction with the surrounding medium or other objects. Damping is caused by inelastic forces such as friction, viscosity, fluid resistance, or air resistance. It can reduce the vibration, speed, and displacement of the object, thereby achieving the effect of stabilizing the adjustable position of the second mounting base 120 under non-stress conditions.

[0052] Specifically, in actual installation, the damping function can be achieved by setting a damping coating between the sliding tenon 122 and the adjusting groove 150, setting the surface roughness, and using material composites. This application does not limit this.

[0053] Based on the above embodiments, the actual usage process of this utility model's multifunctional measuring block is as follows:

[0054] First, the user selects a suitable first gauge block 310 and second gauge block 320 according to the actual measurement needs, and installs the first gauge block 310 on the first mounting base 110 and the second gauge block 320 on the second mounting base 120 respectively.

[0055] Then, according to the actual measurement needs, the second gauge block 320 is moved toward or away from the first gauge block 310, and adjusted to the accurate position by real-time data from the digital display screen 140, so as to compare the length of the product and thus quickly achieve the quality inspection effect. On the other hand, during the selection of the first gauge block 310 and the second gauge block 320, the taper measurement surface 340 of the first gauge block 310 and the second gauge block 320 can also be selected, so as to correspond the taper of a specific part of the product and achieve the effect of rapid quality inspection.

[0056] In some other applications, the multifunctional measuring block of this utility model can also perform the measurement effect of a vernier caliper. For example, by clamping the product with the first measuring block 310 and the second measuring block 320, the actual data of the product can be measured digitally through the display screen 140.

[0057] In summary, this utility model provides a multifunctional measuring block, comprising: a base, a first mounting base fixedly disposed at one end of the base, and a second mounting base slidably disposed at the other end of the base, with a laser rangefinder sensor disposed at the bottom of the second mounting base corresponding to a position within the base; a first gauge block, detachably disposed on the first mounting base, of which several first gauge blocks are provided, each with different measurement parameters; and a second gauge block, detachably disposed on the second mounting base, of which several second gauge blocks are provided, each with different measurement parameters. This utility model, by setting a fixed first mounting base and a sliding second mounting base on the base, and installing the first and second gauge blocks respectively, allows for distance adjustment via the laser rangefinder sensor at the bottom of the second mounting base. This enables a single measuring block to be adjusted to detect various products according to usage requirements. Furthermore, the first and second gauge blocks with different measurement parameters can be replaced, significantly reducing testing costs while facilitating portability and use by testing personnel.

[0058] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
