Description

Technical Field

[0001] This application belongs to the field of eccentric wheel replacement technology, specifically relating to an eccentric side guide wheel installation method and an angle measuring tool. Background Technology

[0002] In continuous production lines, welding machines are key equipment connecting the beginning and end of strip steel. The precision of the welding carriage plays a decisive role in obtaining a good weld, and the precision of most welding carriages is controlled by eccentric side guide wheels. Due to the fast production pace of continuous production lines, when the side guide wheels malfunction or have large precision errors, the trajectory of the welding carriage will become abnormal, requiring timely replacement of the side guide wheels.

[0003] There are currently two adjustment methods for replacing and installing the side guide wheel: 1. Before removal, measure the gap between the side guide wheel and the track. After the new wheel is installed, adjust it according to the measured gap. However, the base is about 500mm away during measurement, making it impossible to see visually. The space is small, making the operation difficult and the operability poor.

[0004] 2. Measuring the positional accuracy of the welding carriage indirectly indicates the adjustment direction of the side guide wheels. This method requires moving the welding carriage multiple times to achieve a new balance with the side guide wheels before determining whether the side guide wheel position is appropriate. The process is complex, inefficient, and cannot meet the need for rapid recovery of welding carriage accuracy during production. Summary of the Invention

[0014] The technical solution adopted to achieve the purpose of this application is as follows: In the third aspect of this application, the present invention also discloses an eccentric side guide wheel installation method, comprising the following steps: Make a first marking line and a third marking line on the eccentric wheel to be replaced. The third marking line is set along the direction of the shortest or longest eccentric distance of the eccentric wheel to be replaced. Make a first second marking line on the fixing plate.

Remove the eccentric wheel to be replaced from the fixing plate and measure the included angle between the first marking line and the third marking line; Select a new eccentric wheel, and draw a fourth and a fifth marking line on the new eccentric wheel. The fourth marking line is set along the direction of the shortest or longest eccentric distance of the new eccentric wheel, and the included angle between the fifth marking line and the fourth marking line is equal to the included angle between the first marking line and the third marking line. Install the new eccentric wheel onto the fixed plate, making the fifth marking line collinear with the second marking line.

[0017] The eccentric side guide wheel installation method disclosed in this application, by creating marking lines on the eccentric wheel to be replaced and the new eccentric wheel, and measuring and copying the relevant included angles, can quickly lock the eccentricity of the welding carriage's eccentric side guide wheel. Unlike traditional methods, it eliminates the need for complex gap measurements or multiple movements of the welding carriage to adjust the side guide wheel position, greatly improving the efficiency of side guide wheel replacement.

Detailed Implementation

[0021] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0024] This invention discloses an eccentric side guide wheel installation method and an angle measuring tool, which can solve the technical problems of poor operability or low efficiency of existing replacement methods. This allows for faster locking of the eccentricity of the welding carriage's eccentric side guide wheel, quick restoration of the welding carriage's accuracy, avoidance of the cumbersome process of adjusting the eccentric side guide wheel and downtime when troubleshooting, and improved efficiency of replacing the side guide wheel of the welding carriage.

[0025] The technical solutions of this application will be described in detail below through specific embodiments and in conjunction with the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0026] See Figure 1 and Figure 2 In the first aspect of this application, a method for installing an eccentric side guide wheel is disclosed, which includes the following steps: A first marking line 210 is randomly made on the eccentric wheel 200 to be replaced, and a first second marking line 110 is made on the fixing plate 100. The second marking line 110 coincides with the extension line of the first marking line 210. Remove the eccentric wheel 200 to be replaced from the fixing plate 100, and draw a third marking line 220 along the direction of the shortest or longest eccentric distance of the eccentric wheel 200 to be replaced; measure the included angle between the first marking line 210 and the third marking line 220. Select a new eccentric wheel 300, and draw a fourth marking line 320 and a fifth marking line 310 on the new eccentric wheel 300. The fourth marking line 320 is set along the direction of the shortest or longest eccentric distance of the new eccentric wheel 300, and the included angle between the fifth marking line 310 and the fourth marking line 320 is equal to the included angle between the first marking line 210 and the third marking line 220. Install the new eccentric wheel 300 onto the fixed plate 100, so that the fifth marking line 310 is collinear with the second marking line 110.

[0027] The eccentric side guide wheel installation method disclosed in this embodiment, by creating marking lines on the eccentric wheel 200 to be replaced and the new eccentric wheel 300, and measuring and copying the relevant included angles, can quickly lock the eccentricity of the welding carriage's eccentric side guide wheel. Unlike traditional methods, it eliminates the need for complex gap measurements or multiple movements of the welding carriage to adjust the side guide wheel position, greatly improving the efficiency of side guide wheel replacement. Because the steps are clear and repeatable, different operators can achieve similar installation results by following this method, which is beneficial for standardized operations in the production process, improving production efficiency and product quality consistency.

[0028] See Figure 3 According to one embodiment of the present invention, a first limiting part 400 is provided at the second marking line 110 of the fixing plate 100. A second limiting part 500 is provided at the fifth marking line 310 of the new eccentric wheel 300, and the second limiting part 500 cooperates with the first limiting part 400 so that the fifth marking line 310 of the new eccentric wheel 300 is collinear with the second marking line 110. After the new eccentric wheel 300 is installed, the first limiting part 400 and the second limiting part 500 are removed.

[0029] The cooperation of the first limiting part 400 and the second limiting part 500 provides precise physical positioning for the installation of the new eccentric wheel 300. Compared with simply relying on manual alignment of the marking lines, the mechanical cooperation of the limiting parts can eliminate human visual errors and operational deviations, ensuring that the fifth marking line 310 of the new eccentric wheel 300 is strictly collinear with the second marking line 110 of the fixing plate 100, thereby ensuring that the eccentric direction of the new eccentric wheel 300 is consistent with that of the original eccentric wheel, greatly improving the accuracy of installation.

[0030] During installation, the limiting part serves to constrain and fix the new eccentric wheel 300, preventing accidental movement or rotation and avoiding misalignment. Even under external interference, the limiting part ensures the stability of the new eccentric wheel 300's position, guaranteeing installation quality.

[0031] Operators do not need to spend a lot of time and effort to accurately align the marking lines. They only need to mate the second limiting part 500 of the new eccentric wheel 300 with the first limiting part 400 of the fixed plate 100 to complete the positioning. This simplifies the installation process, reduces the number of installation steps, and thus improves installation efficiency.

[0032] According to one embodiment of the present invention, both the first limiting part 400 and the second limiting part 500 are magnets, and the first limiting part 400 and the second limiting part 500 tend to attract each other.

[0033] When installing the new eccentric wheel 300, when the second limiting part 500 (the magnet on the new eccentric wheel 300) approaches the first limiting part 400 (the magnet on the fixing plate 100) to a certain distance, the two will attract each other due to magnetic force. This automatic adsorption characteristic helps operators quickly and accurately position the new eccentric wheel 300 in the correct position on the fixing plate 100, reducing the time and effort of manually adjusting the alignment marks and greatly improving installation efficiency.

[0034] The mutual attraction between the magnets can provide additional restraint, effectively preventing the new eccentric wheel 300 from shifting or deflecting due to slight external disturbances (such as slight touches by the operator or vibrations of surrounding equipment) during installation, ensuring that the fifth marking line 310 and the second marking line 110 always remain collinear, thereby improving the precision and accuracy of installation.

[0035] See Figure 4 , Figure 5 , Figure 6 and Figure 7 According to one embodiment of the present invention, one of the first limiting part 400 and the second limiting part 500 is provided with a slot 700, and the other is provided with a block 600, which engages with the slot 700.

[0036] The slot 700 and the block 600 have specific shapes and sizes. When installing the new eccentric wheel 300, the block 600 is inserted along the trajectory of the slot 700, which can provide precise guidance for the new eccentric wheel 300, ensuring that the fifth marking line 310 and the second marking line 110 are accurately collinear, effectively avoiding deviations that may occur during manual installation, and greatly improving the accuracy of installation.

[0037] The snap-fit ​​connection is unique and definitive; installation is only complete when the snap-fit ​​block 600 is correctly inserted into the snap-fit ​​slot 700. This strict fit prevents lateral or longitudinal misalignment of the new eccentric wheel 300 during installation, ensuring the accuracy of the eccentric wheel's installation position and thus guaranteeing that the eccentric side guide wheel can properly perform its guiding and other functions.

[0038] According to one embodiment of the present invention, the first limiting part 400 is bonded or magnetically attracted to the fixing plate 100, and the second limiting part 500 is bonded or magnetically attracted to the new eccentric wheel 300.

[0039] The adhesive or magnetic method makes the installation and removal of the first limiting part 400 and the second limiting part 500 very simple. Operators can quickly fix the limiting parts in the corresponding positions without complicated tools and cumbersome operating procedures. For example, when using magnetic attraction, simply bring the limiting part close to the fixing plate 100 or the new eccentric wheel 300, and it will quickly be attracted into place under the action of magnetic force, which greatly shortens the installation time, improves the overall installation efficiency, and is also very convenient and quick to disassemble.

[0040] According to one embodiment of the present invention, before making the first marking line 210 on the eccentric wheel 200 to be replaced, the eccentric wheel 200 and the fixing plate 100 are removed as a whole. After the new eccentric wheel 300 is installed onto the fixing plate 100, the new eccentric wheel 300 and the fixing plate 100 are reassembled as a whole and the accuracy is restored.

[0041] The eccentric wheel 200 to be replaced and the fixing plate 100 are removed as a whole, allowing for the marking of the first identification line 210 on the eccentric wheel 200 in a relatively independent and stable environment. At this point, the relative positional relationship between the eccentric wheel and the fixing plate 100 is fixed and unaffected by the operation or installation status of other parts of the equipment, ensuring that the first identification line 210 accurately reflects the original installation position and angle of the eccentric wheel on the fixing plate 100. Subsequently, the new eccentric wheel 300 is installed based on this identification line and in conjunction with other identification lines on the fixing plate 100, highly accurately replicating the installation state of the original eccentric wheel and ensuring that the eccentric direction and position of the new eccentric wheel 300 are consistent with the original eccentric wheel.

[0042] If the entire device is not disassembled and instead marked and replaced directly on the equipment, errors can easily occur during marking and installation due to the complex assembly relationships between the various components and the dynamic effects of operation. These errors may also accumulate, resulting in a significant deviation in the installation position of the new eccentric wheel 300. Disassembling the entire device before installation effectively avoids this situation and improves installation accuracy.

[0043] Through the above embodiments, this application has the following beneficial effects or advantages: The eccentric side guide wheel installation method disclosed in this application, by making marking lines on the eccentric wheel 200 to be replaced and the new eccentric wheel 300, and measuring and copying the relevant included angles, can quickly lock the eccentricity of the welding carriage's eccentric side guide wheel. Unlike traditional methods, it eliminates the need for complex gap measurements or multiple movements of the welding carriage to adjust the side guide wheel position, greatly improving the efficiency of replacing the side guide wheel. Setting limiting parts (such as mutual attraction of magnets, cooperation of the slot 700 and the block 600, adhesive bonding, or magnetic attraction) ensures that the fifth marking line 310 is accurately collinear with the second marking line 110 on the fixing plate 100 when the new eccentric wheel 300 is installed, effectively improving the installation accuracy of the eccentric side guide wheel and thus ensuring the running accuracy of the welding carriage. The eccentric side guide wheel installation method provided by this invention has relatively simple steps and is easy for operators to understand and execute.

[0044] Based on the same inventive concept, a second aspect of this application discloses an angle measuring tool, which includes: A curved dial with graduated markings; and The measuring arm is rotatably connected to the arc dial, and the axis of rotation of the measuring arm coincides with the axis of rotation of the arc dial.

[0045] The angle measuring tool disclosed in this embodiment features a clearly defined scale on its arc-shaped dial. When the measuring arm rotates around an axis that coincides with the centerline of the arc-shaped dial, the scale corresponding to the position indicated by the measuring arm directly and accurately reflects the angle of the eccentric guide wheel. This intuitive scale display method avoids errors caused by estimation or complex calculations, greatly improving the accuracy of angle measurement. Because the rotation axis of the measuring arm coincides with the centerline of the arc-shaped dial, it ensures that the movement trajectory of the measuring arm matches the scale distribution of the arc-shaped dial during the measurement process, reducing measurement deviations caused by unreasonable structural design of the measuring tool.

[0046] The measuring tool has a relatively simple structure. The operator only needs to contact the measuring arm with the eccentric wheel, so that the rotation axis of the measuring arm is located at the intersection of the first mark line 210 and the second mark line 110. Then, the measuring arm is rotated and the scale is recorded when the measuring wall coincides with the first mark line 210 and the second mark line 110 respectively. After that, the included angle between the first mark line 210 and the second mark line 110 can be obtained by calculation.

[0047] According to one embodiment of the present invention, the measuring arm is provided with a threaded hole; The angle measuring tool also includes a fixing rod with an external thread for engaging with a threaded hole. The fixing rod is threadedly connected to the measuring arm, and rotating the fixing rod can fix or loosen the measuring arm from the arc dial.

[0048] When the position of the measuring arm needs to be adjusted to suit different measurement requirements, simply rotate the fixing rod to loosen the measuring arm and allow it to rotate freely; after adjusting to the appropriate position, rotate the fixing rod again to securely fix the measuring arm. This operation method is simple and direct, requiring no additional complex tools, greatly saving operation time and effort, and improving the efficiency of measurement work. For example, when measuring the angle of eccentric side guide wheels of different specifications, the position of the measuring arm can be quickly adjusted, and the measurement state can be quickly entered.

[0049] See Figure 8 Based on the same inventive concept, a third aspect of this application discloses a method for installing an eccentric side guide wheel, comprising the following steps: Make a first marking line 210 and a third marking line 220 on the eccentric wheel 200 to be replaced. The third marking line 220 is set along the direction of the shortest or longest eccentric distance of the eccentric wheel 200 to be replaced. Make a first second marking line 110 on the fixing plate 100. The second marking line 110 coincides with the extension line of the first marking line 210. Remove the eccentric wheel 200 to be replaced from the fixed plate 100 and measure the included angle between the first marking line 210 and the third marking line 220. Select a new eccentric wheel 300, and draw a fourth marking line 320 and a fifth marking line 310 on the new eccentric wheel 300. The fourth marking line 320 is set along the direction of the shortest or longest eccentric distance of the new eccentric wheel 300, and the included angle between the fifth marking line 310 and the fourth marking line 320 is equal to the included angle between the first marking line 210 and the third marking line 220. Install the new eccentric wheel 300 onto the fixed plate 100, so that the fifth marking line 310 is collinear with the second marking line 110.

[0050] Compared to the eccentric side guide wheel installation method disclosed in the first aspect, the eccentric side guide wheel installation method disclosed in the third aspect of this application involves first making a first marking line 210 and a third marking line 220 on the eccentric wheel 200 to be replaced, and then removing the eccentric wheel 200 from the fixing plate 100. Making the marking lines on the eccentric wheel 200 beforehand, while the eccentric wheel is still in the installed state, allows the operator to more easily and accurately determine the position and direction of the eccentric wheel, thus making the marking lines more precise. In contrast, if the eccentric wheel is removed first and then the marking lines are made, the eccentric wheel loses the support and positioning of the fixing plate 100, which may increase the difficulty and error in drawing the marking lines. Making the marking lines while the eccentric wheel 200 is in the installed state allows the operator to use the fixing plate 100 and other related components as references to more clearly observe the characteristics and positional relationships of the eccentric wheel, facilitating accurate measurement of the included angle between the first marking line 210 and the third marking line 220.

[0051] See Figure 9Based on the same inventive concept, the fourth aspect of this application discloses a method for installing an eccentric side guide wheel, comprising the following steps: A first marking line 210 is randomly made on the eccentric wheel 200 to be replaced. The first marking line 210 is set along the direction of the shortest or longest eccentric distance of the eccentric wheel 200 to be replaced. A first second marking line 110 is made on the fixing plate 100. The second marking line 110 coincides with the extension line of the first marking line 210. Select a new eccentric wheel 300 and make a fourth marking line 320 on the new eccentric wheel 300. The fourth marking line 320 is set along the direction of the shortest or longest eccentric distance of the new eccentric wheel 300. Install the new eccentric wheel 300 onto the fixing plate 100, so that the fourth marking line 320 is collinear with the second marking line 110.

[0052] Compared to the eccentric side guide wheel installation method disclosed in the first aspect, the eccentric side guide wheel installation method disclosed in the fourth aspect of this application only requires drawing a marking line on the eccentric wheel 200 to be replaced, the fixing plate 100, and the new eccentric wheel 300 to complete the rapid installation of the new eccentric wheel 300. This method only requires three marking line drawing operations, which greatly simplifies the installation process compared to the complex steps involved in the first aspect, such as drawing multiple marking lines and multiple angle measurements and adjustments. Operators do not need to spend a lot of time on complex marking and measurement work, and can quickly complete the installation preparation work of the new eccentric wheel 300, thereby shortening the overall installation time and improving work efficiency. For operators, drawing one marking line is much simpler than drawing multiple marking lines and measuring angles.
