[0032] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a workpiece size adaptive pressure holding machine, including an operating table 1, the top inner wall of the operating table 1 is slidably connected to a moving seat 2, the moving seat 2 has a mobile technology, when the mobile workpiece is installed, the moving seat 2 moves to the left to process the mobile workpiece, and the moving seat 2 moves to the bottom of the mold 15. This is the prior art and will not be described in detail. The outer wall of the moving seat 2 is fixedly connected to a fixed tube 3, and the outer wall of the fixed tube 3 is slidably connected to a slider 4. Figure 4The top of the slider 4 is elastically connected to a wedge 6 through a return spring 5. The wedge 6 is an inclined surface. When the inclined surface is squeezed, the wedge 6 will slide along the inner wall of the slider 4. The side wall of the slider 4 is hinged with an L-plate 8 through a hinge rod 7. The vertical surface of the L-plate 8 will contact the surface of the mobile phone. At the same time, the contact surfaces of the L-plate 8 and the contact plate 9 with the mobile phone are both made of rubber material, which will not cause damage to the mobile phone during the processing process. A contact mechanism is provided on the inner wall of the L-plate 8.

[0033] Reference Figure 5-Figure 6 A hydraulic rod 11 is arranged on the inner wall of the bottom end of the operating table 1. The hydraulic rod 11 converts hydraulic energy into mechanical energy, realizing push-pull operation and force transmission in various engineering and mechanical applications. The movable end of the hydraulic rod 11 is fixedly connected with an insert block 12. The inner wall of the insert block 12 penetrates and is slidably connected with a limit plate 13. The lower end of the limit plate 13 is inclined and can be squeezed by the mold 15. The upper end of the limit plate 13 is convex and can move with the limit plate 13 by pressing the convex. The limit plate 13 is provided with two groups, and the two groups The limit plates 13 are elastically connected by a movable spring 14, one end of the movable spring 14 is fixed to the outer wall of the left limit plate 13, and the other end is fixed to the outer wall of the right limit plate 13. The outer wall of the plug block 12 is plugged with a mold 15, and the mold 15 is a prior art. The mobile phone workpiece is processed by extrusion, and no further details are given here. The outer wall of the limit plate 13 is plugged with the inner side wall of the mold 15, and a groove is provided on the inner side wall of the mold 15. The lower end of the limit plate 13 is plugged with the mold 15 to limit it in one direction.

[0034] Reference Figure 1-Figure 3The top of the slider 4 is fixedly connected to one end of the return spring 5. When the wedge block 6 moves upward, the return spring 5 will be stretched. When resetting, the elastic force of the return spring 5 is used to return the wedge block 6. The other end of the return spring 5 is fixedly connected to the inner side wall of the wedge block 6. The wedge block 6 penetrates and is slidably connected to the inner wall of the slider 4. The slider 4 is plugged into the outer wall of the fixed tube 3. The fixed tube 3 is provided with a plurality of notches corresponding to the wedge block 6, which can allow the wedge block 6 to be plugged into the fixed tube 3 to limit the slider 4 in one direction. The side wall of the slider 4 is hinged to one end of the hinged rod 7. Since the length of the hinged rod 7 is fixed, when the slider 4 moves to the left with one end of the hinged rod 7, the other end of the hinged rod 7 will move closer to each other with the L plate 8. On the contrary, the slider 4 moves to the right with one end of the hinged rod 7 When moving, the other end of the hinged rod 7 will separate from the L-plate 8, and the other end of the hinged rod 7 will be hinged to the bottom end of the L-plate 8. The L-plate 8 is slidably connected to the inner wall of the moving seat 2. The contact mechanism includes a contact plate 9, which is slidably connected to the inner wall of the L-plate 8. The left end of the contact plate 9 is an inclined surface, and its inclined surface will contact and be squeezed with the mobile phone workpiece. There are two groups of contact plates 9, and the two groups of contact plates 9 are elastically connected by positioning springs 10. The circular tubes of the two groups of contact plates 9 are hollow, so that one end of the positioning spring 10 is fixedly connected to the inner wall of the left contact plate 9, and the other end of the positioning spring 10 is fixedly connected to the inner wall of the right contact plate 9. The contact plate 9 contacts the top of the moving seat 2, and the top of the contact plate 9 contacts the bottom of the mold 15.

[0035] Working principle: First, when processing mobile phone workpieces of different sizes, just place the mobile phone workpiece on the top of the moving seat 2, and then move the slider 4 to the left to let the outer wall groove of the fixed tube 3 squeeze the inclined surface of the wedge block 6, so that the wedge block 6 moves upward and stretches the reset spring 5. When the wedge block 6 coincides with the groove of the next fixed tube 3, the reverse elastic force of the reset spring 5 is used to reset the wedge block 6, so that the wedge block 6 is plugged into the outer wall groove of the fixed tube 3, and the entire slider 4 is limited in one direction. When the slider 4 moves to the left, the slider 4 will move with the hinge rod 7 to let the hinge rod 7 pull the L plate 8 and the contact plate 9 close to each other, so that the inclined surface of the contact plate 9 contacts the mobile phone workpiece and is squeezed by the mobile phone workpiece, so that the two groups of contact plates 9 are separated from each other and the positioning spring 10 is stretched, and the reverse elastic force of the positioning spring 10 is used to fix the inner side surface of the contact plate 9 and the vertical surface of the L plate 8 to the mobile phone workpiece, so that the contact plate 9 can position both sides of the mobile phone to adapt to mobile phone workpieces of different sizes.

[0036] When the processing is completed, it is only necessary to move the wedge block 6 upwards and stretch the reset spring 5, and then the wedge block 6 moves the slider 4 and the hinge rod 7 to the right, so that the hinge rod 7 separates the L plate 8 and the contact plate 9 from each other. When the two groups of contact plates 9 are separated and no longer contact the mobile phone workpiece, the reverse elastic force of the positioning spring 10 is used to bring the contact plates 9 closer to each other and reset them. Finally, the L plate 8 returns to its initial position, and the wedge block 6 is released and the reverse elastic force of the reset spring 5 is used to reset the wedge block 6.

[0037] When the mold 15 needs to be disassembled and installed, it is only necessary to press the upper end protrusion of the limit plate 13, so that the limit plates 13 are close to each other and the movable spring 14 is compressed, so that the movable spring 14 is separated from the inner side wall groove of the mold 15, and the mold 15 is separated from the plug block 12 to release the installation. After the disassembly is completed, the upper end protrusion of the limit plate 13 is released, and the reverse elastic force of the movable spring 14 brings the limit plates 13 to separate and reset from each other. When installing, it is only necessary to plug the groove of the mold 15 with the plug block 12, so that the top of the mold 15 squeezes the lower end inclined surface of the limit plate 13, so that the limit plates 13 are close to each other and the movable spring 14 is compressed, and after the lower end of the limit plate 13 coincides with the inner side wall groove of the mold 15, the reverse elastic force of the movable spring 14 is used to reset the limit plate 13, and the lower end of the limit plate 13 is plugged with the inner side wall of the mold 15 to limit the entire mold 15 in one direction, and the installation process is completed.
