[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0030] As shown in Figure 1 - Figure 3 The present application provides a watch dial marking jig 1, which comprises:

[0031] A mounting base 10, which is used to be mounted to a plate body or a frame;

[0032] A guide rail assembly 30, which comprises a guide rail 31, two sliding blocks 33 and a driving member, one end of the guide rail 31 is connected to the mounting base 10, the two sliding blocks 33 are respectively slidingly connected to the guide rail 31, and the driving member is drivingly connected to the sliding blocks 33 to drive the sliding blocks 33 to move along the guide rail 31;

[0033] A measuring assembly, which comprises a first measuring member and a second measuring member, the first measuring member and the second measuring member are respectively mounted to the two sliding blocks 33, the first measuring member is used to measure the side surface of the target roller, and the second measuring member is used to measure the end surface of the target roller.

[0034] Firstly, the jig contains a mounting seat 10. The function of this mounting seat 10 is to fix it on the board or frame that needs to be measured. In this way, the jig can be firmly fixed on the workbench, providing a stable reference for subsequent measurement work.

[0035] Secondly, the jig also includes a guide rail assembly 30. The guide rail assembly 30 is composed of a guide rail 31, two sliders 33 and a driving part. One end of the guide rail 31 is connected with the mounting seat 10, and the two sliders 33 can slide on the guide rail 31 respectively. The function of the driving part is to drive the parts connected with the sliders 33, so that the sliders 33 can move smoothly along the guide rail 31. This design allows the sliders 33 to move freely forward and backward or left and right on the guide rail 31, providing flexible movement space for the measurement assembly.

[0036] Next, the jig also contains a measurement assembly. The measurement assembly is composed of a first measurement part and a second measurement part. The first measurement part and the second measurement part are respectively installed on the two sliders 33. The main function of the first measurement part is to measure the side surface of the target roller, that is, to measure the perpendicularity of the Z-direction plane. The second measurement part is used to measure the end surface of the target roller, that is, to measure the perpendicularity of the X, Y-direction plane. By installing the first measurement part and the second measurement part on the two sliders 33 respectively, comprehensive measurement of the target roller can be realized. The first measurement part and the second measurement part can be a micrometer, which is a high-precision measuring tool used to measure the size, thickness, diameter and other parameters of workpieces. The micrometer has the characteristics of high precision, easy operation and high reliability

[0037] In practical application, the accuracy and stability of the micrometer are crucial to the measurement results. In order to ensure the measurement accuracy, the micrometer needs to be calibrated regularly and preheated before use to eliminate mechanical and temperature errors. In addition, the installation position and angle of the micrometer also need to be accurately adjusted to ensure that its measuring head can accurately contact the measuring surface of the target roller.

[0038] In order to further improve the measurement efficiency and accuracy, the measurement assembly can also be equipped with an automatic reading device. This device can record the measurement data of the micrometer in real time and transmit it to the control console through the data line for analysis and processing. The introduction of the automatic reading device not only reduces the error of manual reading, but also greatly improves the measurement speed, making the whole measurement process more efficient and convenient.

[0039] During the use of the jig, the operator needs to follow certain operating procedures. First, place the target roller in the designated position of the jig and make sure it is fixed firmly. Then, start the driving part to make the sliders 33 drive the micrometer to move along the guide rail 31 to the measurement position of the target roller. During the measurement process, the operator should closely observe the reading change of the micrometer and make fine adjustments as needed to ensure the accuracy of the measurement data.

[0040] Finally, when the measurement is completed, the operator should move the dial gauge back to the initial position and turn off the drive. Then, the measurement data is sorted and analyzed to evaluate the processing quality of the target roller. If the measurement result is found to be unsatisfactory, the parameters of the processing equipment should be adjusted in time to ensure the quality of subsequent products. Through the use of such a jig, the quality control level in the production process can be effectively improved, ensuring that each product meets the predetermined standards.

[0041] The dial gauge jig proposed in this application achieves multi-directional measurement of the target roller by providing a guide rail 31 and two sliders 33 on the guide rail assembly 30, and a first measuring element and a second measuring element on the measuring assembly. The two sliders 33 can slide along the guide rail 31 by the drive of the drive element, so that the first measuring element can be used to measure the side surface of the target roller, i.e., the perpendicularity of the Z-direction plane, while the second measuring element can be used to measure the end surface of the target roller, i.e., the perpendicularity of the X, Y-direction plane. Through the combined measurement of the two measuring elements, the perpendicularity of the X, Y, Z three directions of the shaft can be measured at the same time, thereby significantly improving the measurement accuracy.

[0042] Further, the dial gauge jig also includes a connecting plate 40 and a bottom plate 50, the connecting plate 40 is connected to the mounting seat 10, and the bottom plate 50 is connected to the connecting plate 40 in the horizontal direction, and the guide rail assembly 30 is installed on the bottom plate 50.

[0043] In the design of the dial gauge jig, in addition to the core guide rail assembly 30, other important components are also included to ensure its stability and functionality. First, the connecting plate 40 is one of the key parts of the jig, which is responsible for connecting the jig with the mounting seat 10. The design of the connecting plate 40 needs to have enough strength and stability to ensure that it will not loosen or deform during use. The connecting plate 40 is usually made of metal material to ensure its durability and carrying capacity.

[0044] The bottom plate 50 is another important component of the jig, which is connected to the connecting plate 40 in the horizontal direction. The main function of the bottom plate 50 is to provide a solid platform to support the entire jig system. The design of the bottom plate 50 needs to consider the overall weight distribution and stability to ensure stability in various working environments. Usually, the bottom plate 50 is also made of metal material to ensure its strength and durability.

[0045] The guide rail assembly 30 is the core part of the jig, which is installed on the base plate 50. The main function of the guide rail assembly 30 is to provide accurate positioning and guidance to ensure that the measuring equipment or other tools can move smoothly on the predetermined path. The guide rail assembly 30 usually includes guide rails 31, sliders 33 and related fixing devices. The guide rails 31 are usually manufactured by high-precision machining processes to ensure their smooth surface and high straightness, thereby ensuring the accuracy of the measurement.

[0046] Further, the base plate 50 is connected along the horizontal center line of the mounting seat 10.

[0047] The base plate 50 is connected and arranged along the horizontal center line of the mounting seat 10, ensuring its close combination with the mounting seat 10. By connecting the base plate 50 to the center line, the stress on the connecting plate 40 can be evenly distributed and concentrated at the center position. Such design helps to maintain the connection stability and balance of the base plate 50, thereby ensuring the stability and reliability of the entire structure.

[0048] Further, the mounting seat 10 is a magnetic seat.

[0049] The mounting seat 10 is designed in a magnetic structure. This magnetic seat uses the strong attraction of magnetic force to conveniently fix the equipment at a specific position. Through the use of the magnetic seat, the user can easily be adsorbed on the mounting plate body or the frame body, thereby realizing a stable fixing effect. The design of the magnetic seat not only has the advantages of simple and beautiful appearance, easy operation and quick installation, but also greatly improves the user's experience.

[0050] Further, the dialing jig further comprises a support plate 60, one side of the support plate 60 is connected to the mounting seat 10, and the other side is connected to the bottom of the guide rail 31.

[0051] The function of the support plate 60 is to provide a stable foundation and support for the entire jig. Specifically, one side surface of the support plate 60 is fixed on the mounting seat 10 by mechanical connection, and the other side surface is closely connected with the bottom of the guide rail 31. Such design not only ensures the stability of the jig, but also enables the guide rail 31 to smoothly slide on the support plate 60, thereby realizing accurate measurement and positioning. Through this structure, the dialing jig can effectively complete various precision measurement tasks and ensure the reliability of product quality.

[0052] Further, the support plate 60 is also provided with a through hole 61.

[0053] The support plate 60 is also specially designed with multiple through holes 61. These through holes 61 not only help to reduce stress concentration of the overall structure, but also further improve its stability and durability. Through these carefully arranged through holes 61, the load can be effectively dispersed and transmitted, thereby reducing the impact of stress on the support plate 60 and ensuring its good performance and reliability during long-term use.

[0054] Further, the support plate 60 is provided with multiple through holes 61.

[0055] In the design of the support plate 60, we pay special attention to the layout and number of through holes 61. The support plate 60 is provided with a large number of through holes 61, which are evenly distributed on the surface of the support plate 60. Each through hole 61 is spaced apart to ensure the stability and uniform stress of the structure. This design not only improves the strength and durability of the support plate 60, but also ensures its reliability and safety in actual application. By reasonably arranging the number and spacing of through holes 61, we can effectively disperse stress and reduce local stress concentration, thereby prolonging the service life of the support plate 60. In addition, the evenly distributed through holes 61 also help to dissipate heat, improving the performance of the support plate 60 in high temperature environments. In short, this carefully designed through hole 61 layout makes the support plate 60 perform well in various working conditions, meeting the needs of customers for high performance and high reliability.

[0056] Further, the material selection of the support plate 60 is also crucial. In order to ensure that the support plate 60 can withstand various stresses and loads during long-term use, high-strength metal materials such as aluminum alloy or carbon steel are usually selected. These materials not only have good mechanical properties, but also can provide sufficient rigidity and corrosion resistance, thereby prolonging the service life of the jig.

[0057] Further, the surface treatment of the support plate 60 is also very important. In order to improve its wear resistance and corrosion resistance, the surface of the support plate 60 is usually treated by anodic oxidation or coated with a protective film. Anodic oxidation treatment can form a dense oxide film on the metal surface, effectively preventing oxidation and corrosion, while also enhancing the hardness and wear resistance of the surface. Coating a protective film can further improve the chemical corrosion resistance of the support plate 60, ensuring that the jig maintains good performance in various working environments.

[0058] Further, the design of the support plate 60 also considers compatibility with other components of the jig. For example, the connection between the support plate 60, the mounting seat 10 and the guide rail 31 usually adopts a standardized mechanical interface for quick disassembly and replacement. This design not only facilitates the maintenance and maintenance of the jig, but also makes the jig adaptable to different sizes and shapes of workpieces, improving its application range and flexibility.

[0059] Further, the mounting seat 10, the connecting plate 40, the bottom plate 50, the guide rail assembly 30 and the support plate 60 are all made of aluminum.

[0060] The mounting seat 10, the connecting plate 40, the bottom plate 50, the guide rail assembly 30 and the support plate 60 are all made of aluminum. Aluminum, as a metal material, is widely used in various industrial fields due to its lightweight and high-strength characteristics. Lightweight means that aluminum material is lighter in weight under the same volume, which helps to reduce the overall weight of the equipment, thereby improving the convenience of transportation and installation. At the same time, the high-strength characteristics of aluminum material ensure good stability and durability of these components when subjected to pressure and load. The selection of this material not only improves the performance of the equipment, but also provides reliable protection for long-term use.

[0061] Further, the connecting plate 40, the bottom plate 50 and the support plate 60 are integrally formed.

[0062] This design not only improves the overall stability and durability, but also greatly simplifies the assembly process, allowing seamless integration of each part to ensure the integrity and reliability of the structure. Through this integrated design, the performance of the entire device is significantly improved, and users also have a more convenient user experience.
