[0036] Combination Figures 1 to 5 The utility model proposes an embodiment, wherein the fixture adjustment device comprises an upper die 1 and a pressure measuring assembly 2. The upper die 1 comprises a cover plate 11, a movable die 12 and an adjusting member 13, wherein the movable die 12 is connected to the cover plate 11 through the adjusting member 13, and the adjusting member 13 is used to adjust the pressure of the movable die 12. The pressure measuring assembly 2 is detachably connected to the upper die 1, and the pressure measuring assembly 2 is provided with a pressure detector 22, which abuts against the movable die 12 and is used to detect the pressure of the movable die 12.

[0037] Specifically, the pressure measuring assembly 2 is a base structure, on which a pressure detector 22 is arranged, and the pressure detector 22 has a detection end arranged in a vertical direction. The cover plate 11 of the upper mold 1 is connected to the pressure measuring module group, and the cover plate 11 is also provided with a laser channel 102. When the upper mold 1 is connected to the pressure measuring assembly 2, the pressure detector 22 is located in the laser channel 102. The upper mold 1 is also movably connected to the movable mold 12, and the movable mold 12 abuts against the detection end of the pressure detector 22. The pressure detector 22 can read the pressure of the movable mold 12 on the pressure detector 22. The adjusting member 13 is connected between the cover plate 11 and the movable mold 12 to adjust the pressure of the movable mold 12 on the pressure detector 22.

[0038] Through this embodiment, a detachable pressure measuring assembly 2 having a pressure detection function is used, and the pressure measuring assembly 2 and the upper mold 1 are first connected together, and the pressure of the movable mold 12 on it is detected by the pressure detector 22, and the adjusting member 13 is adjusted according to the degree to change the pressure of the movable mold 12. After knowing that the pressure of the movable mold 12 reaches the required requirement, the pressure measuring assembly 2 is disassembled, and the pressure measuring assembly 2 on which the workpiece is placed is replaced, and the pressure measuring assembly 2 is connected so that the pressure of the movable mold 12 is under its own control when it abuts against the workpiece.

[0039] Combination Figures 1 to 5 The utility model proposes an embodiment, the pressure measuring assembly 2 includes a base plate 21 and the pressure detector 22, the base plate 21 is detachably connected to the upper mold 1, the base plate 21 is provided with a mounting groove 211, and the pressure detector 22 is detachably connected to the mounting groove 211.

[0040] Specifically, the cover plate 11 is detachably connected to the bottom plate 21, and the cover plate 11 and the bottom plate 21 enclose a receiving cavity 101. The bottom plate 21 is provided with a mounting groove 211, and the pressure detector 22 is connected at the groove. The detection end of the pressure detector 22 extends into the receiving cavity 101. The movable mold 12 is connected to the receiving cavity 101 in a sliding manner up and down, and the movable mold 12 abuts and presses on the detection end under the influence of gravity. The adjusting member 13 also applies pressure to the movable mold 12 so that the movable mold 12 is pressed on the detection end.

[0041] According to this embodiment, the mounting groove 211 is designed on the bottom plate 21, so that the mounting groove 211 is arranged corresponding to the vertical direction of the bottom plate 21. When detecting the pressure of the movable mold 12, the pressure detector 22 is placed in the mounting groove 211 so that the output end is aligned with the movable mold 12 to detect the pressure of the movable mold 12 on it.

[0042] Combination Figures 1 to 5 The utility model proposes an embodiment, the installation groove 211 has a first end and a second end, the pressure detector 22 is movably connected to the installation groove 211 and abuts against the first end or the second end;

[0043] The pressure detector 22 detects the pressure at one end of the movable mold 12 when it abuts against the first end, and detects the pressure at the other end of the movable mold 12 when it abuts against the second end.

[0044] Specifically, the movable mold 12 is a long strip block structure, the mounting groove 211 is a waist-shaped hole, and the length direction of the mounting groove 211 is consistent with the length direction of the movable mold 12. The mounting groove 211 has a first end and a second end that are relatively arranged. It can be understood that the first end and the second end are arc walls that adapt to the cylindrical wall of the pressure detector 22, and the wall between the first end and the second end has a smooth transition, so that the pressure detector 22 can avoid moving from the first end to the second end.

[0045] According to this embodiment, when detecting the pressure, the pressure detector 22 first measures the pressure exerted on it by the movable mold 12 at the first end, and then moves the pressure detector 22 to the second end to detect the pressure exerted on it by the movable mold 12. Thus, the pressure distribution on both sides of the movable mold 12 can be known, and the pressure on both sides can be adjusted to balance the movable mold 12.

[0048] Through this embodiment, a plurality of pressure detectors 22 are arranged on the bottom plate 21, so that the pressure of the movable mold 12 on the pressure detector 22 can be measured at multiple positions at the same time. The pressure distribution of the movable mold 12 can be observed more intuitively. Further adjusting the pressure of the movable mold 12 on the pressure detector 22 is more comprehensive. It can be understood that the movable mold 12 is an integral structure, and adjusting the pressure on one side will also cause the pressure at other positions to change. By adjusting the movable mold 12 through multiple pressure detectors 22, it is possible not to adjust the pressure at one place so that the pressure on the other side of the movable mold 12 changes accordingly, resulting in pressure imbalance.

[0049] Combination Figures 1 to 5 The utility model proposes an embodiment, the bottom plate 21 is further provided with a mounting notch 212 connected to the mounting groove 211 , and the mounting notch 212 is used for the pressure detector 22 to enter or leave the mounting groove 211 .

In addition, the installation notch 212 also exposes the space in the installation slot 211, and then the pressure detector 22 can be manually controlled to change its position, that is, to move from the first end to the second end.

Furthermore, the diameters of the two positioning posts 16 are inconsistent, so that the direction in which the upper mold 1 connects to the bottom plate 21 is unique, which has a fool-proof effect. Magnets 18 are provided on both sides of the upper mold 1 and the bottom plate 21, and one of the upper mold 1 and the bottom plate 21 is set as a positive pole and the other is set as a negative pole, so that the upper mold 1 and the bottom plate 21 will fit tightly together due to the adsorption of the magnet 18 when they are installed. Two magnets 18 are provided on opposite sides of the mounting groove 211. Together with the positioning posts 16, they are respectively located at the four corners of the bottom plate 21. It can be understood that if the bottom plate 21 and / or the upper mold 1 are metal structures, only one magnet 18 can be provided so that the bottom plate 21 and the upper mold 1 can be magnetically attracted together.

[0054] According to this embodiment, there is no need for complicated connection methods such as screws and bolts, and the upper mold 1 and the bottom plate 21 can be connected together through the positioning pillars 16 and the magnets 18.
