[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 6This utility model provides a technical solution: an anti-tilt mounting base, including a table body 1 and a table leg leveling component 2. The table leg leveling component 2 is located at the bottom corner of the table body 1. Both ends of the outer wall of the table body 1 are rotatably connected to an extension component 3. A positioning plate 4 is slidably connected to the surface of the table body 1. A reverse screw 5 is located below the positioning plate 4 and is rotatably connected to the inside of the table body 1. A protective cover 6 is bolted to the surface of the table body 1. The positioning plate 4 is located inside the protective cover 6. A level 7 is embedded in the table body 1 through slots opened at both ends of its surface. The protective cover 6 is located between the level 7.
[0027] The table leg leveling assembly 2 consists of an outer table leg 201 and an inner table leg 202. The inner table leg 202 is slidably connected to the corresponding sliding grooves on both sides of the inner wall of the outer table leg 201 through sliders at both ends of its outer wall. The outer table leg 201 is rotatably connected to a lead screw 203 through a servo motor installed inside it. The inner table leg 202 is threadedly connected to the outer wall of the lead screw 203 through a threaded hole opened at its axis.
[0028] The expansion component 3 consists of an expansion panel 301 and a T-shaped steering plate 302, which are connected by a hinge.
[0029] The inner wall of the protective cover 6 has slide rails 601 on both sides, and a flap 602 is slidably connected between the slide rails 601.
[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the inner table legs 202 are distributed at the four corners of the bottom of the table body 1 and are integrally connected to the table body 1. Pressure sensors are fixedly connected to the top of the inner table legs 202 and the corresponding corner of the bottom of the table body 1. The distribution of the inner table legs 202 at the four corners of the bottom of the table body 1 allows the pressure sensors to comprehensively monitor the pressure changes at each support point of the table body 1. When the press is working, no matter which direction or part is unevenly stressed, the pressure sensors at the corresponding corners can capture the pressure changes in time, thereby accurately reflecting the stress state of the table body 1 and providing comprehensive data support for judging whether it is tilted. The control system can adjust the height of the inner table legs 202 that have abnormal pressure to restore the table body 1 to a horizontal position, ensuring that the press is always in an ideal working state. This precise adjustment method can effectively ensure the processing accuracy of the press and improve product quality.
[0031] In this embodiment, as Figure 5As shown, the inner table leg 202 and the lead screw 203 form a spiral transmission structure, and the inner table leg 202 forms a lifting structure on the inner wall of the outer table leg 201 through the lead screw 203; by issuing a command through the control system, the inner table leg 202 can be raised and lowered without complicated manual operation or additional tools. This convenient operation method improves the efficiency of leveling work.
[0032] In this embodiment, as Figure 2 and Figure 3 As shown, at both ends of the outer wall of the table body 1, corresponding to the positions of the expansion component 3, two upper and lower limiting pins are fixedly connected. The surface of the T-shaped turning plate 302 has slots for movably connecting these two limiting pins. The "C"-shaped groove on the surface of the T-shaped turning plate 302 corresponds to the limiting pin above the surface of the table body 1. The arc-shaped groove at both ends and the long strip in the middle of the surface of the T-shaped turning plate 302 corresponds to the limiting pin below the surface of the table body 1. The T-shaped turning plate 302 forms a flip structure with the "C"-shaped groove and the limiting pin above the surface of the table body 1. By setting two upper and lower limiting pins at both ends of the outer wall of the table body 1 and cooperating with the different slots on the surface of the T-shaped turning plate 302, the operator can easily unfold and retract the expansion component 3. When it is necessary to expand the working area, the expansion component 3 can be quickly unfolded to increase the usable space of the table body 1. When it is not needed, it can be easily retracted without occupying too much space, allowing the table body 1 to return to its original state, meeting the diverse needs for desktop space in different scenarios.
[0033] In this embodiment, as Figure 1 and Figure 6 As shown, the positioning plates 4 are symmetrically distributed about the vertical center line of the table body 1, and each positioning plate 4 has a strip rubber pad glued to its surface. The bottom of each positioning plate 4 extends into the corresponding sliding groove on the surface of the table body 1 and is threaded to the outer wall of the reverse screw 5. At the same time, the positioning plates 4 are in relative motion through the reverse screw 5. When the pressure mechanism processes or inspects the workpiece, the symmetrical positioning plates 4 can apply force evenly from both sides, keeping the workpiece in the center position and ensuring uniform pressure distribution, thereby improving the accuracy of processing or inspection. The rubber pads have good elasticity and can automatically adjust the contact area and pressure distribution according to the shape of the workpiece when clamping it. They can also further improve the coefficient of friction, thereby improving the clamping force. By integrating the positioning plates 4, the versatility of the base is increased, so that no additional fixtures need to be assembled during the use of the press.
[0034] In this embodiment, as Figure 1 and Figure 5As shown, the level instruments 7 are symmetrically distributed about the vertical center line of the table body 1, and the center point between the inner table legs 202 coincides with the horizontal point of the level instrument 7. The symmetrical distribution of the level instruments 7 and their coincidence with the center point of the inner table legs 202 allow the operator to intuitively understand the tilt direction and approximate degree of the table body 1 by observing the level instruments 7. Combined with the pressure sensor, the operation can be further improved by using the table leg leveling component 2, shortening the time and increasing work efficiency.
[0035] In this embodiment, as Figure 4 As shown, both the protective cover 6 and the flip plate 602 are composed of a stainless steel metal frame and double-layered tempered glass embedded in the frame. The top and bottom of the protective cover 6 are openwork surfaces. The presence of the protective cover 6 further enhances the protective performance. Its openwork surfaces at the top and bottom will not interfere with the normal operation of the pressure mechanism, ensuring that the pressure mechanism can smoothly contact the workpiece and complete the work, thus guaranteeing the continuity and efficiency of the equipment operation. During the processing, when it is necessary to change the workpiece, the operator only needs to slide and flip the flip plate 602 to easily take out or put in the workpiece, saving operation time and improving work efficiency. Moreover, after flipping, it slides and flips to the openwork surface at the top of the protective cover 6, without occupying too much desktop space.
[0036] The usage and advantages of this utility model: The anti-tilt mounting base operates as follows during use:
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during subsequent installation, the pressure mechanism is first installed on the sufficient surface area reserved on the table 1, ensuring that the pressure end of the pressure mechanism is directly above the positioning plates 4. Based on the size of the workpiece to be processed or inspected, the workpiece is placed between the positioning plates 4. The spacing between the positioning plates 4 is adjusted by rotating the reverse screw 5. The strip rubber pads glued to the surface of the positioning plates 4 are elastic and can deform under pressure according to the shape of the workpiece, while increasing the coefficient of friction with the workpiece, improving the clamping force, and firmly fixing the workpiece. If it is necessary to increase the working area of the table 1, the expansion panel 301 is pulled, causing the T-shaped steering plate 302 to rotate along the axis of the lower limit pin on the side wall of the table 1. When the T-shaped turning plate 302 moves, the C-shaped groove on its surface slides and connects with the upper limit pin on the side wall of the table body 1. During the flipping process, the originally reversed C-shape gradually becomes a forward C-shape. After the flipping is complete, the other groove of the T-shaped turning plate 302, which is arc-shaped at both ends and elongated in the middle, engages and is positioned with the lower limit pin on the side wall of the table body 1. This allows the expanded panel 301 to complete a 90° flip via the hinge, thereby expanding the capacity of the table body 1. The pressure mechanism is activated to apply pressure to the workpiece for processing or inspection. During this process, the protective cover 6 provides certain protection, and its upper and lower hollow surfaces do not affect the normal operation of the pressure mechanism. If replacement is required... The workpiece is slidably flipped by the slide rail 601 and the flip plate 602, providing convenient operation. The inner table legs 202, distributed at the four corners of the bottom of the table body 1, have pressure sensors at their tops where they connect to the bottom of the table body 1, which monitor the pressure on each table leg in real time. When the press is working normally, the pressure at each support point is balanced; if tilting occurs, the pressure at different support points changes, and the pressure sensors collect these change signals in real time. The operator can also monitor the levelness of the table body 1 in real time using a level 7 (HA-58S). The control system, combined with the pressure change signals collected by the pressure sensors, determines whether the mounting base is tilted and the direction and degree of tilt. For example, if a pressure sensor at a certain corner... If the pressure value is significantly different from other angles and the level 7 shows a tilt in the corresponding direction, the specific location of the tilt can be determined. After the control system determines that the mounting base is tilted, it activates the table leg leveling component 2. The servo motor inside the outer table leg 201 drives the lead screw 203 to rotate. The rotation of the lead screw 203 causes the inner table leg 202 to rise or fall within the outer table leg 201. Based on the tilt direction and degree, the control system controls the servo motor of the corresponding outer table leg 201 to precisely adjust the rise and fall of the corresponding inner table leg 202, changing the height of the corresponding position of the table body 1, realizing automatic leveling of the mounting base, ensuring the horizontal stability of the pressure mechanism during operation, and ensuring the processing or testing accuracy.
