As the manufacturing industry continues to develop towards higher precision and efficiency, the market is placing increasingly higher demands on the inspection speed, measurement accuracy, and equipment versatility of such inspection devices.

[0003] However, existing Gothic groove inspection devices for upper and lower plates of displacement stages still have some limitations in practical use. For example, their single inspection process is time-consuming, affecting the efficiency of batch inspection; the obtained inspection data has a certain degree of error, making it difficult to fully meet the strict control requirements of high-precision displacement stages for key dimensions; and most devices can only inspect workpieces of specific specifications or with a single orientation, lacking universal adaptability to different sizes and groove orientations, resulting in the need to equip various special inspection tools on actual production lines, increasing equipment costs and management complexity.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a general-purpose Goethe groove detection device for the upper and lower plates of the displacement stage is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a universal displacement stage upper and lower plate Goethe groove detection device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a general-purpose displacement table upper and lower plate Goethe groove detection device, comprising: a base, a dial indicator fixing seat disposed on the top of the base, a digital display dial indicator disposed in the dial indicator fixing seat, and a test component disposed on the top of the base;

[0007] The test assembly includes: a fixed block, a top plate, and two claws. The upper surface of the base is fixedly connected to the bottom of the fixed block. A movable lower plate is fixedly connected to the upper surface of the base. A movable upper plate is slidably connected to the top of the movable lower plate. A spring-loaded moving unit is provided between the movable lower plate and the movable upper plate. The bottom of the top plate is fixedly connected to the top of the movable upper plate. The bottom of one of the claws is bolted to the upper surface of the fixed block, and the bottom of the other claw is bolted to the upper surface of the top plate.

[0008] The bottom of the dial indicator mounting base is fixedly connected to the upper surface of the base, and one end of the digital dial indicator passes through the dial indicator mounting base and is fixedly connected.

[0009] In a preferred embodiment of this utility model, several slots are provided on opposite sides of the two claws, and high-precision steel balls are engaged in the slots.

[0010] In a preferred embodiment of this invention, the high-precision steel ball is made of a high-hardness, wear-resistant material.

[0011] In a preferred embodiment of this utility model, the rebound moving unit is a spring, which is disposed between the lower moving plate and the upper moving plate. The upper surface of the lower moving plate is provided with a guide rail, and the bottom of the upper moving plate is provided with a sliding groove that matches the guide rail.

[0012] In a preferred embodiment of this utility model, the guide rail is located in the slide groove and is slidably connected.

[0013] In a preferred embodiment of this utility model, the two claws are detachably connected to the fixing block and the top plate respectively by means of bolts.

[0014] In a preferred embodiment of this utility model, the digital dial indicator is fixed in the dial indicator mounting base by a locking screw.

[0015] In a preferred embodiment of this utility model, a plurality of foot pads are fixedly connected to the bottom of the base.

[0016] In a preferred embodiment of this utility model, an anti-slip pad is adhered to the bottom of each of the foot pads.

[0017] In a preferred embodiment of this utility model, the digital display dial indicator is an electronic digital display dial indicator with IP53 protection rating, measurement accuracy of not less than 0.001mm, and a reverse pressure function of the measuring rod.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a universal displacement stage upper and lower plate Gothic groove detection device. By adopting a bidirectional configurable jaw setting, the jaws are embedded with high-precision steel balls. By adjusting the orientation of the two jaws, the high-precision steel balls are set opposite or opposite to each other, thereby adapting to different detection scenarios where the Gothic groove opening is downward or upward. This allows the device to universally detect Gothic grooves with multiple orientations without changing tools or adjusting the device structure, directly improving the flexibility and efficiency of detection. Compared with existing detection devices that can often only detect in a single direction and require multiple special tools or complex adjustments, the device body avoids the problems of equipment redundancy and cumbersome operation.

[0020] (2) This utility model provides a general-purpose displacement stage upper and lower plate Goethe groove detection device. Through the setting of the spring movement unit, including the spring and guide rail slide structure, the upper plate and the moving plate are connected. The spring provides automatic rebound force, so that the claw can adaptively fit the Goethe groove wall during detection. The guide rail ensures smooth linear movement, which can realize automatic centering and stable contact during the detection process, reduce human intervention, and directly ensure the consistency and reliability of measurement. Compared with the existing technology, which relies on manual adjustment, is prone to human error and is time-consuming to operate, the device body improves the accuracy through automatic compensation. Furthermore, this not only enhances the repeatability of detection, but also reduces the skill burden of the operator, and is suitable for high-frequency or large-volume quality control links.

[0021] (3) This utility model provides a general-purpose displacement table upper and lower plate Goethe groove detection device. By using a high-precision digital display dial indicator, which has an IP53 protection level, a measurement accuracy of not less than 0.001mm, and a reverse pressure function of the measuring rod, it is securely installed by the dial indicator fixing base and directly measures the displacement change of the jaws. It can provide accurate digital readings, ensure that the detection results are intuitive and reliable, and directly avoid visual errors and data recording errors. Compared with the existing technology that often uses mechanical dial indicators or low-precision tools, the readings are not intuitive and are easily affected by environmental interference.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figure 1 As shown, a general-purpose displacement table upper and lower plate Goethe groove detection device includes: a base 1, a dial indicator fixing seat 3 set on the top of the base 1, a digital display dial indicator 10 set in the dial indicator fixing seat 3, and a test component set on the top of the base 1.

[0027] The test assembly includes: a fixed block 5, a top plate 4, and two claws 6. The upper surface of the base 1 is fixedly connected to the bottom of the fixed block 5. A movable lower plate 9 is fixedly connected to the upper surface of the base 1. A movable upper plate 8 is slidably connected to the top of the movable lower plate 9. A spring-loaded moving unit is provided between the movable lower plate 9 and the movable upper plate 8. The bottom of the top plate 4 is fixedly connected to the top of the movable upper plate 8. The bottom of one claw 6 is bolted to the upper surface of the fixed block 5, and the bottom of the other claw 6 is bolted to the upper surface of the top plate 4. The two claws 6 are detachably connected to the fixed block 5 and the top plate 4 respectively by bolt connection. Several slots are opened on opposite sides of the two claws 6, and high-precision steel balls 7 are engaged in the slots. The high-precision steel balls 7 are made of high-hardness wear-resistant material.

[0028] The spring-loaded moving unit is a spring, which is set between the lower moving plate 9 and the upper moving plate 8. The upper surface of the lower moving plate 9 is provided with a guide rail, and the bottom of the upper moving plate 8 is provided with a groove that matches the guide rail.

[0029] It should be noted that the jaws 6 have multiple slots, each containing a high-precision steel ball 7. The steel ball is made of high-hardness and wear-resistant material to ensure durability and accuracy during long-term use. By adjusting the orientation of the two jaws 6, the steel balls can be set opposite to each other or opposite each other, which can adapt to different detection scenarios where the Goethe groove opening is facing down or up, achieving universal detection. The detection mode can be quickly switched without changing tools, thereby improving the flexibility and efficiency of detection.

[0030] The spring-loaded moving unit consists of a spring and a guide rail slide structure. The spring is set between the moving lower plate 9 and the moving upper plate 8 to provide automatic spring-loaded force, so that the chuck 6 can adaptively fit the Goethe groove wall during detection. The matching of the guide rail and the slide ensures that the moving upper plate 8 moves smoothly along a straight line, reducing shaking and deviation. This enables automatic centering and stable contact during the detection process, reduces human intervention, and ensures the consistency and reliability of the measurement. It is especially suitable for high-frequency or large-volume quality control.

[0031] The testing component uses the fixed block 5 and the top plate 4 as a support base. Combined with the coordinated work of the claw 6 and the spring-loaded moving unit, the device can maintain high precision and stability in various Goethe slot testing scenarios. Furthermore, the combination of the high-precision steel ball 7 and the automatic spring-loaded mechanism not only reduces the skill burden on the operator but also enhances the repeatability of the test, directly improving the overall quality control effect.

[0032] like Figure 1 As shown, the bottom of the dial indicator mounting base 3 is fixedly connected to the upper surface of the base 1. One end of the digital dial indicator 10 passes through the dial indicator mounting base 3 and is fixedly connected. The digital dial indicator 10 is fixed in the dial indicator mounting base 3 by locking screws. The digital dial indicator 10 is an electronic digital dial indicator 10 with IP53 protection rating, measurement accuracy of not less than 0.001mm, and a reverse pressure function of the measuring rod.

[0033] It should be noted that the dial indicator mounting base 3 serves as the load-bearing structure of the digital dial indicator 10. The dial indicator mounting base 3 provides a stable reference for measurement. By fixing the dial indicator inside it, the dial indicator mounting base 3 can effectively isolate external vibration and interference caused by operation, ensuring the rigidity of the measurement system and guaranteeing the accuracy and repeatability of the measurement readings.

[0034] The digital micrometer 10 features high measurement accuracy, IP53 protection rating, and probe reverse pressure function. High accuracy ensures that minute deviations in the test data can be accurately captured, meeting the quality control requirements of precision components. The IP53 protection rating can prevent dust intrusion and vertically falling water droplets to a certain extent, enhancing its adaptability and durability in general industrial environments. Together, they can ensure the reliability and intuitiveness of the test results.

[0035] The probe's reverse pressure function is key to achieving automated measurement, enabling the probe to automatically reset after being pressed. It works in conjunction with the device's spring-loaded movement unit to achieve continuous and rapid detection of the Goethe groove.

[0036] Example 1:

[0037] This embodiment describes the detection configuration and operation process when the Goethe groove of the workpiece to be tested is facing downwards;

[0038] When the Goethe groove of the workpiece to be inspected is facing downward, first configure the device, fix the two jaws 6 to the bolts on the fixing block 5 and the top plate 4 respectively, adjust the direction of the jaws 6 on the fixing block 5 so that the side with the high-precision steel ball 7 is facing outward of the device, and then tighten the bolts to fix it.

[0039] Adjust the jaws 6 on the top plate 4 so that one side of the high-precision steel ball 7 faces outwards from the other side. Even if the high-precision steel ball 7 sides of the two jaws 6 are set in opposite directions, after configuration, align the Goethe groove of the workpiece and fit it onto the two adjusted jaws 6. At this time, place the workpiece downwards so that the inner wall of the Goethe groove contacts the high-precision steel ball 7 on the jaws 6. Under pressure, the upper moving plate 8 will slide downwards along the guide rail of the lower moving plate 9, compressing the spring between them. The rebound force provided by the spring ensures that the high-precision steel ball 7 contacts the inner wall of the Goethe groove. The measuring rod of the digital micrometer 10 moves along with it under the guidance of the micrometer fixing base 3, and directly displays the displacement reading on the screen, thereby completing the accurate detection of the downward-facing Goethe groove.

[0040] Example 2:

[0041] This embodiment describes the detection configuration and operation process when the Goethe groove opening of the workpiece to be tested is facing upwards;

[0042] When it is necessary to inspect a workpiece with the Goethe groove opening facing upwards, reconfigure the chuck 6, loosen the fixing bolts, and flip the chuck 6 on the fixing block 5 so that the high-precision steel ball 7 faces the inside of the device.

[0043] Adjust the claws 6 on the top plate 4 so that one side of their high-precision steel ball 7 faces inward, so that the high-precision steel ball 7 sides of the two claws 6 are set opposite each other, and retighten the bolts.

[0044] After configuration, the entire device is lifted so that it straddles the Goethe plate of the workpiece, with the two jaws 6 positioned on either side of the Goethe plate. The device is then lowered so that the high-precision steel balls 7 on the jaws 6 are aligned with the outer wall of the Goethe plate. Under the weight of the device and the action of the spring-loaded moving unit, the upper moving plate 8 drives the top plate 4 and the jaws 6 connected to it to move inwards, ensuring that the high-precision steel balls 7 are tightly fitted against the outer wall of the Goethe plate. The guide rail groove structure between the lower moving plate 9 and the upper moving plate 8 ensures the smoothness and straightness of the movement. The digital dial indicator 10 detects and displays the displacement of the jaws 6 in real time, thus achieving high-precision measurement of the upward-facing Goethe groove.

[0045] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
