Description
Technical Field
[0001] The utility model relates to the field of automobile parts manufacturing, in particular to a displacement-proof press bottom plate fixing device. Background Art
[0002] The anti-displacement press bottom plate fixing device is a device used to ensure that the bottom plate of the press does not displace or deflect during operation. It is widely used in stamping workshops in the manufacturing industry. For example, in the stamping production lines of automobile manufacturers, large stamping machines used to produce automobile body parts need to frequently perform high-intensity stamping operations. If the bottom plates of these stamping machines are displaced, it will not only affect the accuracy of the stamped parts, but may also cause damage to the mold and increase production costs.
[0003] Existing base plate fixing devices usually use bolts to fix the base plate to the punching machine, and adjust the number, position and spacing of the bolts on the base plate according to the size, shape and type of pressure exerted by the press base plate, so that the bolts are evenly distributed on the edge of the base plate and key stress-bearing areas to ensure that the pressure is evenly distributed, thereby ensuring that the base plate will not be displaced during operation.
[0004] However, the existing anti-displacement press bottom plate fixing device still has the following shortcomings when it is actually used. For example, if the bottom plate does not meet the sufficient flatness and horizontality requirements during installation, it will cause a certain slope on the bottom plate surface. When the punching machine is working, the pressure distribution on the bottom plate will be uneven, which can easily cause the bottom plate to be displaced. Therefore, the utility model proposes an anti-displacement press bottom plate fixing device. Utility Model Content

[0013] As a preferred embodiment, both ends of the fixing column are fixedly connected to the limiting plate, and a rubber pad is sleeved on the fixing column between the slider and the limiting plate.
[0014] The technical effect of adopting the above technical solution is to increase the friction coefficient between the punching machine and the fixed column, and improve the stability of the fixed base plate during installation.

According to the rotation direction of the adjustment bracket, it is convenient to control whether the pressure sensor detects the horizontal state of the fixed base plate, which is conducive to improving work efficiency.
[0017] As a preferred embodiment, a fixing plate is fixedly connected to the second rotating shaft, a fixing bolt is slidably connected to the fixing plate, and the fixing bolt is threadedly connected to the punching machine.

As the driven wheel rotates, it will drive the screw to move along the thread line and push the fixing column to fine-tune the height of the fixed base plate to ensure that it remains horizontally installed on the punching machine. This method can effectively compensate for minor errors caused by the processing or assembly process, prevent the uneven pressure distribution caused by these deviations, and thus avoid displacement of the fixed base plate during operation.

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0032] As shown in Figure 1 - Figure 4 The embodiment provides a technical scheme: a displacement-preventing press machine bottom plate fixing device, which comprises a punch press 1, the punch press 1 is provided with a fixed assembly 2, the punch press 1 is provided with an adjusting assembly 3 on one side close to the fixed assembly 2, and the punch press 1 is provided with a detection assembly 4 on one side close to the fixed assembly 2.
[0033] As shown in Figure 1 - Figure 2 The fixed assembly 2 comprises a fixed bottom plate 21 and a fixed column 23, the fixed bottom plate 21 is arranged on the punch press 1, the fixed column 23 is fixedly connected to one side of the fixed bottom plate 21 close to the punch press 1, and the fixed column 23 is slidably connected with the punch press 1.
[0034] As shown in Figure 1 - Figure 2As shown, the adjusting component 3 includes a rotating shaft 31 and a sliding rod 32. The rotating shaft 31 is rotatably connected to both sides of the punching machine 1. One end of the rotating shaft 31 is fixedly connected to a driving wheel 33. The inside of the punching machine 1 is rotatably connected to a driven wheel 34 on the side close to the driving wheel 33. The driven wheel 34 is rotatably connected to the punching machine 1 with a screw 35. The sliding rod 32 is slidably connected to the side of the punching machine 1 close to the rotating shaft 31. One end of the sliding rod 32 close to the driven wheel 34 is fixedly connected to a fixed wheel 37. The fixed wheel 37 is clamped with the driven wheel 34. By opening an inner groove on the punching machine 1 that matches the fixed column 23, placing the fixed base plate 21 on the punching machine 1, and inserting the fixed column 23 inside the inner groove, the adjusting component 3 is used to check Measure whether the fixed base plate 21 is placed horizontally. If the surface of the fixed base plate 21 is tilted, turn the knob on the rotating shaft 31, the driven wheel 34 rotates following the driving wheel 33 and drives the screw 35 to rotate through the driven wheel 34. The screw 35 moves along the thread line on the punching machine 1 and the driven wheel 34 and pushes the fixed column 23 to fine-tune the height of the fixed base plate 21, so that the fixed base plate 21 remains horizontally installed on the punching machine 1, which can effectively compensate for the slight offset caused by processing errors or installation deviations, and prevent the pressure from being unevenly distributed on the fixed base plate 21 when the punching machine 1 is working, thereby avoiding displacement of the fixed base plate 21, and an annular hollow slider 26 is installed on the driven wheel 34 to make the driven wheel 34 rotate on the punching machine 1.
[0035] Furthermore, Figure 2 As shown, the end of the slide rod 32 away from the fixed wheel 37 is fixedly connected to a connecting plate 36, and a spring 38 is fixedly connected between the connecting plate 36 and the punching machine 1. By installing the slide rod 32, the slide rod 32 drives the fixed wheel 37 to separate from the driven wheel 34 and drives the spring 38 to extend through the connecting plate 36. When the adjustment of the fixed bottom plate 21 is completed, the slide rod 32 is released, the force on the spring 38 disappears, and the spring 38 drives the slide rod 32 to reset so that the fixed wheel 37 and the driven wheel 34 are re-engaged, and the driven wheel 34 is fixed, which is beneficial to improve the stability of the bottom fixing device.
[0036] Furthermore, Figure 3 As shown, the top of the fixed base plate 21 is fixedly connected to the mold 22, and a spring piece 25 is sleeved on the fixed column 23. Sliders 26 are provided at both ends of the spring piece 25. The sliders 26 are slidably connected to the fixed column 23. By installing the fixed column 23 inside the inner groove opened on the punching machine 1, when the punching machine 1 is working, a rubber pad 24 is installed on the fixed column 23 to fix it. After long-term use, the rubber pad 24 will wear out, causing a gap between the rubber pad 24 and the inner groove. At this time, the spring piece 25 automatically stretches and pushes the slide 26 to squeeze the rubber pad 24, causing the rubber pad 24 to expand and keep fixed to the fixed column 23, thereby improving the stability of the fixed column 23 installed on the punching machine 1.
[0037] Furthermore, Figure 3 As shown, both ends of the fixed column 23 are fixedly connected to the limiting plate 27, and a rubber pad 24 is sleeved on the fixed column 23 between the slider 26 and the limiting plate 27. By installing the rubber pad 24 between the punching machine 1 and the fixed column 23, the friction coefficient between the punching machine 1 and the fixed column 23 is increased, thereby improving the stability of the fixed base plate 21 during installation.
[0038] In order to more accurately reflect the horizontal state of the fixed base plate 21 during installation, as shown in FIG. Figure 4 As shown, the detection component 4 includes a bracket 41 and a pressure sensor 42. The bracket 41 is arranged on the punching machine 1. The punching machine 1 and the bracket 41 are provided with a second rotating shaft 43. The second rotating shaft 43 is rotatably connected to the punching machine 1, and the second rotating shaft 43 is fixedly connected to the bracket 41. The pressure sensor 42 is fixedly connected to the side of the bracket 41 close to the punching machine 1. By arranging the pressure sensors 42 at multiple positions of the bracket 41, the pressure data of multiple points on the fixed base plate 21 are obtained at the same time, so as to make a comprehensive and detailed assessment of the overall levelness of the fixed base plate 21, which can more accurately reflect whether the fixed base plate 21 is maintained in a horizontal state, and facilitate subsequent installation work. In addition, the multiple pressure sensors 42 are installed at the same height on the bracket 41. The bracket 41 is rotatably connected to the punching machine 1 through the second rotating shaft 43, so that the pressure sensor 42 moves with the bracket 41. According to the rotation direction of the adjustment bracket 41, it is convenient to control whether the pressure sensor 42 detects the horizontal state of the fixed base plate 21, which is conducive to improving work efficiency.
[0039] Furthermore, Figure 4 As shown, a fixing plate 44 is fixedly connected to the second rotating shaft 43, and a fixing bolt 45 is slidably connected to the fixing plate 44. The fixing bolt 45 is threadedly connected to the punch 1. By rotating the fixing bolt 45, the fixing bolt 45 fixes the bracket 41 through the thread groove opened in the upper punch 1 and cooperates with the second rotating shaft 43 and the fixing plate 44, thereby improving the stability of the pressure sensor 42 during detection and ensuring the accuracy of detection.
[0040] Working principle: Figure 1 - Figure 4 As shown:
[0041] During use: first place the fixed base plate 21 on the punching machine 1, insert the fixed column 23 into the inner groove, rotate the rotating shaft 2 43, the rotating shaft 2 43 drives the fixed plate 44 and the bracket 41 to rotate in the direction of the fixed base plate 21, and the input end of the pressure sensor 42 contacts the surface of the fixed base plate 21, and rotate the fixing bolt 45. The fixing bolt 45 fixes the bracket 41 by opening the thread groove of the upper punching machine 1 and cooperates with the rotating shaft 2 43 and the fixed plate 44 to keep the pressure sensor 42 stable. Then read the reading on the pressure sensor 42. If the fixed base plate 21 is in a tilted state, press the slide bar 32, the slide bar 32 drives the fixed wheel 37 to separate from the driven wheel 34, and drives the spring 38 to stretch, and then rotates, the knob on the rotating shaft 1 31 The driven wheel 34 rotates with the driving wheel 33 and drives the screw 35 to rotate through the driven wheel 34. The screw 35 moves along the thread line and pushes the fixed column 23 to fine-tune the height of the fixed base plate 21, so that the fixed base plate 21 remains horizontally placed on the punching machine 1. The slide bar 32 is released, and the spring 38 drives the fixed wheel 37 and the driven wheel 34 to re-engage through the slide bar 32, fixing the driven wheel 34 and the screw 35. Finally, the fixed base plate 21 is fixed to the punching machine 1 using conventional bolts, nuts and gaskets. The bracket 41 is rotated, and the pressure sensor 42 is separated from the fixed base plate 21, so that the fixed base plate 21 is installed horizontally on the punching machine 1, which can effectively compensate for the slight offset caused by processing errors or installation deviations and avoid displacement of the fixed base plate 21.
