DETAILED DESCRIPTION

[0023] The technical scheme of the utility model will be further described in detail below with specific examples and in conjunction with the drawings. The described examples are only some of the examples of the utility model, but not all of the examples.

[0024] Example 1: Refer to Figures 1 to 5 The steel seal scale line adjusting structure mainly comprises a protractor disc 13, a steel seal shaft 3, a transmission screw 12, a protractor tooth disc 11, a steel seal wheel bearing seat 6, a steel seal 2 and the like. The protractor disc 13 is arranged on the steel seal shaft 3 and connected with the steel seal shaft 3 in a spline fit mode. The spline fit design is one of the highlights of the whole structure. Compared with the traditional connection mode, the spline fit can greatly enhance the tightness and stability of the connection. In the long-term industrial production environment, the equipment will inevitably face various vibrations, impacts and the like. However, thanks to the characteristics of the spline fit, the protractor disc 13 and the steel seal shaft 3 will not produce worrying shaking phenomenon, thereby providing a solid foundation for the accurate adjustment of the steel seal scale line, ensuring the stability of the scale line in the production process and avoiding problems such as scale line deviation caused by unstable structure, effectively improving the qualified rate of products.

[0025] Around the periphery of the protractor disc 13, a plurality of transmission screws 12 are evenly arranged. These transmission screws 12 are not randomly arranged, but are accurately clamped into the tooth openings of the ring surface of the protractor tooth disc 11. The protractor tooth disc 11 is a key component of the transmission link, and the shape and distribution of the tooth openings thereof are matched with the transmission screws 12. When fine adjustment operation is needed, the staff only needs to gently rotate the protractor disc 13 to drive the transmission screw 12 to rotate, and then clamp it into the tooth opening of the protractor tooth disc 11 to move, so as to realize fine adjustment of the steel seal scale line. The fine adjustment process is accurate and smooth, which can meet the strict requirements of the fineness of the scale line in different production scenes, greatly improving the production efficiency and product quality.

[0026] The other end of the steel seal shaft 3 is connected with the steel seal wheel bearing seat 6. This connection design not only ensures the stable support of the steel seal shaft 3, but also provides a strong guarantee for the fixation of the steel seal 2. The upper end of the steel seal 2 is fixed on the steel seal shaft 3, and an axle end nut 1 is arranged at the upper end thereof. Before actual adjustment operation, the staff can first perform a coarse adjustment by adjusting the axle end nut 1 on the steel seal 2. The design of the axle end nut 1 is simple but practical. By rotating the nut, the position of the steel seal 2 can be preliminarily adjusted, so as to provide a general range for subsequent fine adjustment operation, so that the whole adjustment process is more orderly and efficient.

[0027] The lower end of the steel seal wheel bearing seat 6 is provided with a connecting nut 9, and the lower end of the connecting nut 9 is provided with a steel seal rotary gear 10. The steel seal rotary gear 10 is stably fixed on the bearing, which can keep the steel seal rotary gear 10 stable during rotation and reduce the transmission error caused by gear shaking. The steel seal rotary gear 10 accurately transmits external power to the steel seal shaft 3 and drives the steel seal 2 to rotate correspondingly.

[0028] The lower end of the protractor 13 is connected with a bracket 8, and the bracket 8 is provided with a spring 81. The presence of the spring 81 makes the protractor 13 have a certain elastic buffering effect during adjustment, which can effectively reduce the risk of damage caused by improper operation or external impact, and also improves the accuracy of adjustment to a certain extent. One end of the bracket 8 is also connected with a separation connecting rod 71, and the separation connecting rod 71 is connected with the foot pedal 7. The staff only needs to step on the foot pedal 7 slightly, and then the protractor 13 can be driven to move downward through the separation connecting rod 71, so that the transmission screw 12 on the protractor 13 is separated from the indexing tooth disc 11, and the unlocking effect is achieved. This foot pedal unlocking design makes the operator not need to manually pry open the transmission screw 12 and the indexing tooth disc 11 during adjustment, which greatly reduces the operation difficulty and labor intensity, and improves the adjustment efficiency.

[0029] Overall, the steel seal scale adjustment structure described in the embodiment is in the shape of a long strip. This shape design not only meets the installation and layout requirements of industrial equipment, but also makes the whole structure more compact and beautiful. The components are arranged in order in the long strip structure, and the connection and cooperation between them are more closely, which further improves the stability and reliability of the whole adjustment structure.

[0030] Embodiment 2: Refer to Figures 1 to 5The steel stamp scale line adjusting structure mainly consists of a protractor disc 13, a steel stamp shaft 3, a transmission screw 12, a protractor tooth disc 11, a steel stamp wheel bearing seat 6, a steel stamp 2, and other components. These components have undergone strict precision control and quality inspection during design and manufacturing to ensure the high performance of the entire adjusting structure. The protractor disc 13 is ingeniously arranged on the steel stamp shaft 3 and connected between them through spline fitting. Spline fitting is a mechanical connection method that processes a certain number and shape of key teeth on the shaft and hub to tightly combine them together, which can transmit large torque and has good coaxiality and positioning accuracy. This spline fitting design is one of the highlights of the entire structure. Compared with traditional connection methods such as key connection or pin connection, spline fitting can greatly enhance the tightness and stability of the connection. In the long-term industrial production environment, the equipment will inevitably face various vibrations, impacts, and other situations. However, thanks to the characteristics of spline fitting, the protractor disc 13 and the steel stamp shaft 3 will not shake, thereby providing a solid foundation for the accurate adjustment of the steel stamp scale line, ensuring the stability of the scale line during production, avoiding scale line deviation caused by unstable structure, effectively improving the product qualification rate, and reducing economic losses caused by product quality problems.

[0031] Around the protractor disc 13, several transmission screws 12 are evenly arranged. The transmission screws 12 are inserted into the tooth openings of the protractor tooth disc 11. The protractor tooth disc 11, as a key component of the transmission link, has a tooth opening shape and distribution that matches the transmission screw 12. When fine adjustment is needed, the staff only needs to gently turn the protractor disc 13 to achieve fine adjustment of the steel stamp scale line. The fine adjustment process is accurate and smooth, which can meet the strict requirements of scale line precision in different production scenarios, greatly improving production efficiency and product quality. For example, in some high-precision mechanical part processing, the precision requirement of the steel stamp scale line is very high, and this adjusting structure can easily cope with it, ensuring that every product meets the high-quality requirements.

[0032] The other end of the steel stamp shaft 3 is connected to the steel stamp wheel bearing seat 6, which is usually made of high-strength material and has good rigidity and wear resistance, capable of bearing the centrifugal force and axial force generated by the steel stamp shaft 3 during rotation, ensuring the stable operation of the steel stamp shaft 3. The upper end of the steel stamp 2 is firmly fixed on the steel stamp shaft 3, and the upper end is also provided with an axle nut 1.

[0033] The design of the shaft end nut 1 is simple but practical. By rotating the shaft end nut 1, the position of the steel seal 2 can be preliminarily adjusted, providing a general range for subsequent fine adjustment, making the entire adjustment process more orderly and efficient. Before the actual adjustment operation, the staff can first adjust the shaft end nut 1 on the steel seal 2 for a rough adjustment, quickly adjusting the steel seal 2 to the target position, and then fine-tuning through the index plate 13 and transmission screw 12. This combination of rough and fine adjustment greatly improves the efficiency and accuracy of the adjustment, saving operation time and reducing operation difficulty. The lower end of the steel seal wheel bearing seat 6 is provided with a connecting nut 9, and the lower side of the connecting nut 9 is provided with a steel seal rotary gear 10. The steel seal rotary gear 10 is stably fixed on the bearing, which makes the steel seal rotary gear 10 stable during rotation, reducing transmission errors caused by gear shaking.

[0034] The quality of the steel seal rotary gear 10 directly affects the performance of the entire adjustment structure in actual production, so advanced processing technology and high-precision detection equipment are used in the manufacturing process to ensure the gear shape accuracy and meshing performance of the gear, so that it can still maintain good transmission effect during long-term use.

[0035] The lower side of the index plate 13 is connected with the bracket 8, and the bracket 8 is provided with a spring 81. The presence of the spring 81 makes the index plate 13 have a certain elastic buffering effect during adjustment, which can effectively reduce the risk of damage caused by improper operation or external impact, and also improves the accuracy of adjustment to a certain extent. One end of the bracket 8 is also connected with the separation connecting rod 71, and the separation connecting rod 71 is connected with the foot pedal 7.

[0036] The staff only needs to step on the foot pedal 7 gently, which can drive the index plate 13 to move down through the separation connecting rod 71, so that the transmission screw 12 on the index plate 13 is separated from the index gear plate 11, achieving the function of unlocking. This foot pedal unlocking design makes the operator not need to manually pry apart the transmission screw 12 and the index gear plate 11 during adjustment, greatly reducing the operation difficulty and labor intensity, and improving the adjustment efficiency. In actual operation, the operator can easily achieve quick unlocking and locking through the foot pedal 7, which is convenient and efficient, especially in the case of frequent adjustment, the advantages of this design are more obvious.

[0037] The steel seal scale line adjusting structure described in the embodiment is in a long strip shape, which not only meets the installation and layout requirements of industrial equipment, but also makes the whole structure more compact and beautiful. The components are arranged in order in the long strip structure, and the connection and cooperation between them are more compact, further improving the stability and reliability of the whole adjusting structure. In industrial production sites, space is often limited, and the long strip design makes the adjusting structure easy to install on various equipment without occupying too much space, which is also conducive to the overall layout and maintenance of the equipment.

[0038] The lower end of the protractor 13 is provided with a Z-shaped hook 14, one end of which is embedded in the groove below the protractor 13. This design makes the protractor 13 more convenient and fast during installation and removal, and also increases the stability of the connection between the protractor 13 and the transmission screw 12. The structure of the Z-shaped hook 14 is simple and the manufacturing cost is low. In actual use, the Z-shaped hook 14 can effectively prevent the protractor 13 from accidentally falling off during adjustment, ensuring the smooth progress of the adjustment process.

[0039] A bearing 5 is provided between the steel seal shaft 3 and the steel seal wheel bearing seat 6, and one end of the bearing 5 is sleeved with a bearing end cover 4. The setting of the bearing 5 makes the steel seal shaft 3 rotate more stably, reduces the energy loss caused by friction, and improves the transmission efficiency. The bearing end cover 4 plays a role in fixing and protecting the bearing 5, preventing the bearing 5 from loosening or damaging during high-speed operation. This design not only prolongs the service life of the steel seal shaft 3, but also reduces the maintenance cost of the equipment.

[0040] The diameter of the protractor tooth disc 11 is slightly smaller than that of the protractor 13. This design makes the protractor tooth disc 11 more closely fit under the protractor 13 during installation, reducing the transmission error caused by the gap. At the same time, the diameter of the protractor tooth disc 11 is slightly smaller than that of the protractor 13, which also makes the transmission screw 12 more stable when it is clamped into the tooth opening of the protractor tooth disc 11, and is not easy to loosen or fall off.

[0041] The size of the tooth opening of the transmission screw 12 corresponds to that of the protractor tooth disc 11. This design makes the transmission screw 12 more closely fit when it is clamped into the tooth opening of the protractor tooth disc 11, reducing the transmission error caused by the gap between the tooth openings. The size of the tooth opening of the transmission screw 12 corresponds to that of the protractor tooth disc 11, which also makes the transmission screw 12 move more smoothly in the tooth opening of the protractor tooth disc 11, improving the accuracy of the adjustment.

[0042] In summary, the steel seal scale line adjusting structure in the embodiment realizes precise and convenient adjustment of the steel seal scale line through ingenious component design and mutual cooperation, while having high stability and durability, which can effectively meet the strict requirements of steel seal scale line adjustment in industrial production, and has wide application prospect and promotion value.

[0043] The present application is not limited to the details of the foregoing illustrative examples, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
