Description

Technical Field

[0001] This utility model relates to a tooling, and more particularly to a tooling for detecting the straightness of a crossbeam guide rail, belonging to the field of tooling detection technology. Background Technology

[0002] In the manufacturing and debugging of screen printing equipment, the accuracy and effective adjustment of the straightness of the beam guide rail are crucial to ensuring the overall performance of the equipment and the printing quality. Currently, the debugging method typically involves placing the beam and gauges on shims, using a testing assembly consisting of an auxiliary extension plate and measuring tools to measure the straightness of the beam guide rail, and then adjusting the beam guide rail based on the measurement results.

[0003] However, with the rapid development of the screen printing industry, products are trending towards larger sizes, leading to increasingly larger crossbeams for the mounting rails of large printing presses. When using the aforementioned debugging methods, the straightness of the crossbeam guide rails on large printing presses fluctuates significantly. Analysis reveals three main reasons for this problem: First, the relative position between the crossbeam and the gauge block cannot be effectively fixed. Even slight touches or operations during debugging can cause slight changes in their relative position, resulting in variations in the straightness of the crossbeam guide rail and a significant decrease in measurement and debugging accuracy. Second, the large weight of the crossbeam inevitably causes slight vibrations when placed on shims, causing the crossbeam and gauge block to be out of alignment, affecting measurements and preventing the measured data from accurately reflecting the true straightness of the crossbeam guide rail. Third, existing debugging methods lack flexibility and are difficult to adapt to crossbeams of different sizes. Therefore, the low testing accuracy of the tooling and its inability to adapt to crossbeam guide rails of different sizes have become key technical challenges that urgently need to be addressed in this field. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling to solve the problems of low measurement and debugging accuracy, poor flexibility, and inability to accurately measure and effectively adjust the straightness of crossbeam guide rails of different sizes in existing tooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for detecting the straightness of a crossbeam guide rail, comprising:

[0006] A frame for placing a crossbeam, with a crossbeam guide rail above the crossbeam to be tested;

[0007] The square gauge is fixedly mounted on the frame along the length of the frame.

[0008] A magnetic base is provided, which is mounted on the guide rail slider of the crossbeam guide rail. A dial indicator is mounted on the magnetic base, and the probe of the dial indicator is always in contact with the side of the square gauge in order to read the directional deviation of the magnetic base as it slides along the crossbeam guide rail.

[0009] Furthermore, clamping members for fixing the crossbeam are respectively provided on the frame near both ends of the crossbeam, so that the crossbeam can be detachably mounted on the frame.

[0010] Furthermore, the frame is provided with beam support plates for supporting the beam at positions near both ends of the beam; the clamping member is fixedly mounted on the beam support plate.

[0011] Each of the crossbeam support plates is provided with two fasteners, which are respectively arranged opposite to each other along the width direction of the crossbeam to position the degree of freedom of the crossbeam in the width direction.

[0012] Furthermore, guide rails are respectively provided on the frame near both ends of the crossbeam, and the guide rails are laid parallel to the length direction of the frame; the crossbeam support plate is correspondingly arranged on the guide rails and moves along the guide rails to accommodate crossbeams of different lengths.

[0013] Furthermore, a guide groove is provided on the side of the guide rail along the length direction of the guide rail; a slider is sleeved on the guide groove, and the crossbeam support plate is provided on the slider.

[0014] Furthermore, a boss structure is provided on the frame along the length of the frame, forming a crossbeam placement platform area and a raised square placement platform area on the frame.

[0015] Furthermore, the height of the boss structure is adjustable so that the probe of the dial indicator is always in contact with the side of the square gauge.

[0016] Furthermore, the square gauge has a preset height to accommodate beams and beam guide rails of different heights.

[0017] Furthermore, the boss structure is located at the central axis of the frame, making the cross-section of the frame in the width direction convex. Three placement platforms are formed on the frame: a square placement platform area with a central protrusion and two crossbeam placement platform areas on both sides, so as to adjust the two crossbeam guide rails simultaneously.

[0018] The beneficial effects of this utility model are as follows: The tooling provided in this application, by detachably mounting the crossbeam on the frame, can accurately and stably determine the relative positional relationship between the crossbeam and the square gauge, which helps to improve the accuracy of the tooling in measuring and adjusting the straightness of the crossbeam guide rail; at the same time, it can also simplify the installation, fixing and disassembly of the crossbeam, effectively shorten the preparation time for debugging, and greatly improve the debugging efficiency; it solves the problems of low accuracy in measuring and adjusting the straightness of the crossbeam guide rail and low debugging efficiency caused by the vibration of the crossbeam and the square gauge during the debugging process of existing tooling.

[0019] The tooling provided in this application fixes and limits the crossbeam in multiple directions through clamping and fixing parts, which can further ensure the fixed relative positional relationship between the crossbeam and the square gauge, effectively avoid the impact of crossbeam position changes on measurement and debugging accuracy during debugging, and thus significantly improve the debugging accuracy, reliability and debugging efficiency.

[0020] The tooling provided in this application allows the crossbeam support plate to move along the guide rails on the frame, thereby enabling the tooling to adapt to crossbeam guide rails of different sizes. This greatly improves the flexibility, adaptability, and debugging efficiency of the tooling, meeting diverse debugging needs.

[0021] Compared to shims, the frame structure in this application is more stable, effectively reducing the vibration caused by the heavy weight of the large machine beam. This allows the measurement data to more accurately reflect the true straightness of the beam guide rail, making the fixture applicable to a wider range of beam guide rail sizes. Simultaneously, by setting a boss structure on the frame, the relative positions of the beam and the square gauge are effectively defined, preventing changes in their relative positions due to slight touches or operations during debugging, thereby improving the accuracy of beam guide rail straightness measurement and debugging. Positioning the boss structure at the frame's central axis allows the fixture to simultaneously adjust the beam guide rails on both beams, further improving debugging efficiency.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Please see Figure 1A preferred embodiment of this application discloses a tooling comprising a frame 1 serving as the main support for the entire tooling, a square gauge 2 fixedly mounted along its length, and a magnetic gauge holder 6. The frame 1 houses a crossbeam 3, which is detachably placed parallel to the square gauge 2 on the frame 1. A crossbeam guide rail 5, including a guide rail slider 51, is mounted on the crossbeam guide rail 3. The magnetic gauge holder 6 is mounted on the guide rail slider 51 of the crossbeam guide rail 5, and a dial indicator is mounted on the magnetic gauge holder 6. The probe of the dial indicator is always in contact with the side of the square gauge 2, so that when the magnetic gauge holder 6 and the dial indicator slide synchronously along the crossbeam guide rail 5, the directional deviation of the magnetic gauge holder 6 along the crossbeam guide rail 5 can be read, providing an accurate basis for measuring the straightness of the crossbeam guide rail 5. Detachably mounting the crossbeam 3 on the frame 1 not only facilitates the installation and removal of the crossbeam 3 but also ensures that the relative positional relationship between the crossbeam 3 and the square gauge 2 meets the debugging requirements, thus improving the efficiency and accuracy of debugging.

[0033] To further ensure the accuracy and stability of the debugging process, such as Figure 2 As shown, clamping members 41 for fixing the crossbeam 3 are respectively provided on the frame 1 near both ends of the crossbeam. The clamping members 41 allow the crossbeam 3 to be detachably and securely mounted on the frame 1, while simultaneously fixing the relative position of the crossbeam 3. This prevents changes in relative position during debugging from affecting measurement and debugging accuracy, resulting in more precise and reliable straightness adjustment of the crossbeam guide rail 5. In this embodiment, to facilitate quick disassembly and installation of the crossbeam, the clamping member 41 is preferably an elbow clamp that is easy to operate, has moderate and stable clamping force. In other embodiments, the clamping member 41 can also be other components that can achieve clamping and fixing effects to meet the usage requirements of different scenarios.

[0034] like Figure 3As shown, crossbeam support plates 7 are respectively installed on the frame 1 at the positions supporting both ends of the crossbeam 3. These crossbeam support plates 7 have sufficient strength and stability to provide stable and reliable support for the crossbeam 3. Clamping members 41 are fixedly installed on the crossbeam support plates 7 to clamp and fix the crossbeam 3 placed on the crossbeam support plates 7, ensuring that the crossbeam 3 maintains a stable position during the debugging process, effectively avoiding measurement and debugging errors caused by relative position changes, and ensuring accurate debugging of the straightness of the crossbeam guide rail 5. Since the clamping members 41 are installed at both ends of the crossbeam 3, they can limit the crossbeam 3 in the left and right directions, effectively preventing the relative position of the crossbeam 3 from changing in the left and right directions, that is, limiting the degree of freedom of the crossbeam 3 in its length direction. It should be noted that, in order to further improve the stability of the relative position of the crossbeam 3, each crossbeam support plate 7 is provided with two fixing members 42; and the two fixing members 42 are respectively set opposite to each other along the width direction of the crossbeam 3 to limit the degree of freedom of the crossbeam 3 in its width direction, preventing the position of the crossbeam 3 from changing in the front and back directions. In this embodiment, to facilitate the quick disassembly and installation of the crossbeam, the fastener 42 preferably uses an L-shaped fixing plate and matching bolts and nuts; in other embodiments, the fastener 42 can also be selected from other components that can achieve the fixing effect to meet the usage requirements in different scenarios.

[0035] Guide rails 8 are respectively provided on the frame 1 near both ends of the crossbeam 3, and the guide rails 8 are laid parallel to the length direction of the frame 1. The crossbeam support plate 7 is correspondingly set on the guide rail 8 and can slide along the guide rail 8. By adding the guide rail 8, the fixture can be adapted to crossbeams 3 of different lengths. That is, when adjusting the crossbeam guide rail 5 on crossbeams 3 of different lengths, the crossbeam support plate 7 can be easily moved to accurately place the crossbeam 3 in the appropriate position, thereby meeting diverse adjustment needs and greatly improving the efficiency and flexibility of the adjustment work. In this embodiment, a guide groove 9 is provided on the side of the guide rail 8 along the length direction of the guide rail 8, and a slider 10 is provided below the crossbeam support plate 7. The slider 10 is fitted outside the guide rail 8 and slides with the guide rail 8. Due to the presence of the slider 10, the crossbeam support plate 7 can slide along the guide rail 8. In other embodiments, other connection methods that allow the crossbeam support plate 7 to slide along the guide rail 8 can also be used.

[0036] On the frame 1, a boss structure 11 is provided along its length direction to form a beam placement platform area 12 and a raised square gauge placement platform area 13 on the frame 1, which are respectively used to place the beam 3 and the square gauge 2. By setting the boss structure on the frame 1, a dedicated beam placement platform area 12 and a square gauge placement platform area 13 are formed, which can effectively define the relative positions of the beam 3 and the square gauge 2, and avoid the relative position change of the two caused by slight touch or operation during the debugging process, thereby improving the accuracy of the straightness measurement and debugging of the beam guide 5. In this embodiment, the boss structure 11 is integrally formed with the frame 1; this integrally formed structural design can not only enhance the overall strength and stability of the structure, but also reduce the connection error between components, which helps to improve the accuracy and reliability of the tooling. And, the height of the boss structure 11 does not exceed the height of the beam 3, so that the probe of the dial indicator placed on the guide rail slider 51 can always abut against the side surface of the square gauge 2, thereby ensuring the accuracy and reliability of the measurement data and providing solid data support for the debugging work. In other embodiments, the boss structure 11 may be integrally formed with the frame 1, or may not be integrally formed with the frame 1 and its height is adjustable. When the boss structure 11 is integrally formed with the frame 1, the height of the boss needs to be designed in combination with the heights of components such as the square gauge 2, the beam 3, and the beam guide 5 to ensure that the probe height of the dial indicator is within the side surface range of the square gauge 2. In addition, the square gauge 2 can also be designed as a marble square gauge with a preset height to adapt to the debugging of beams 3 and beam guides 5 with different heights, further improving the versatility and flexibility of the tooling.

[0037] In this embodiment, as Figure 4 shown, the boss structure 11 is arranged at the central axis position of the frame 1, making the cross-section of the frame 1 along the width direction in a "convex" shape, and forming three placement platforms on the frame 1, namely the middle raised square gauge placement platform area 13 and the beam placement platform areas 12 on both sides, so as to debug two beam guides 5 simultaneously and improve the debugging efficiency. In other embodiments, the setting position of the boss structure 11 is not fixed and can be reasonably set according to factors such as actual production requirements, the overall structure of the frame 1, and debugging process requirements, such as setting it at a position close to the side surface of the frame 1, etc., to achieve different functions and application scenarios.

[0038] The assembly and debugging of the above tooling are as follows: Place the frame 1 on a stable ground to ensure that the frame 1 is in a horizontal state; fix the square gauge 2 along the length of the frame 1 and parallel to the length of the frame on the square gauge placement platform area 13 of the frame 1; adjust the position of the crossbeam support plate 7 on the guide rail 8 according to the length of the crossbeam 3, that is, by sliding the slider 10 along the guide groove 9 to move the crossbeam support plate 7 to a suitable position, and then use the locking device to fix the slider 10 on the guide rail 8 to ensure that the position of the crossbeam support plate 7 is stable; place the crossbeam 3 parallel to the square gauge 2 on the crossbeam support plate 7, and use the clamping device 41 and the fixing device 42 to clamp and fix the crossbeam 3 to ensure that the crossbeam will not move during the debugging process; place the crossbeam guide rail 5 on the crossbeam 3, place the magnetic gauge base 6 on the guide rail slider 51 of the crossbeam guide rail 5, and make the probe of the dial indicator always abut against the side of the square gauge 2.

[0039] During the debugging process, first adjust the probe of the dial indicator to align with the side of the square gauge; then slowly move the guide slider 51 on the crossbeam guide rail 5 so that the magnetic base 6 and the dial indicator slide synchronously along the crossbeam guide rail 5. During the sliding process, observe and record the changes in the dial indicator readings, i.e., the directional deviation of the dial indicator probe relative to the crossbeam guide rail 5 at different positions of the guide slider 51. Based on the recorded directional deviation values, adjust the clamping parts 41 and the fixing parts 42 to first adjust the parallelism of the crossbeam 3 relative to the square gauge. Then, move the guide slider 51 again so that the magnetic base 6 and the dial indicator slide synchronously along the crossbeam guide rail 5. Observe and record the changes in the dial indicator readings, and based on the recorded directional deviation values, make reasonable fine adjustments to the corresponding parts of the crossbeam guide rail 5, such as adjusting the tightness of the mounting bolts of the crossbeam guide rail 5. Afterward, move the guide slider 51 on the crossbeam guide rail 5 multiple times so that the magnetic base 6 slides along the crossbeam guide rail 5 to measure the straightness of the crossbeam guide rail 5. If multiple crossbeam guide rails 5 are installed on the crossbeam 3, then each crossbeam guide rail 5 is measured and adjusted separately. The dial indicator installed on the magnetic base 6 can be a graduated dial or a digital display mechanism.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
