[0033] Please refer to Figures 1-4 This utility model provides a multi-workpiece pneumatic fixing device, including a support mechanism, a clamping mechanism, a drive mechanism, and a feeding mechanism. Through the cooperation of these mechanisms, it achieves the function of simultaneously clamping, fixing, and feeding multiple workpieces; wherein,

[0034] Supporting institutions, including support platform 1;

[0035] The clamping mechanism is set on the top surface of the support platform 1, including two symmetrically sliding movable upright plates 2 that are slidably set on the top surface of the support platform 1. The inner side plate of the movable upright plate 2 is provided with a clamping plate 3 through a quick-release assembly. The clamping plate 3 and the corresponding movable upright plate 2 are limited and fixed by a locking assembly.

[0036] In a preferred embodiment, linear guide rails 4 are symmetrically fixed on the top surface of the support platform 1. The linear guide rails 4 are embedded inside the support platform 1. The length direction of the bottom surface of the movable upright plate 2 is perpendicular to the length direction of the linear guide rails 4. The linear guide rails 4 are provided with two parallel ones, and two sliders are slidably provided on each linear guide rail 4. The top surface of the sliders on the same side of the two linear guide rails 4 is fixedly connected to the bottom surface of one movable upright plate 2 to realize the movement of the movable upright plate 2 along the length direction of the linear guide rails 4.

[0037] In a preferred embodiment, the movable upright plate 2 is arranged parallel to the clamping plate 3, and the bottom surface of the clamping plate 3 is arranged higher than the top surface of the support platform 1, that is, the clamping plate 3 is suspended in the air, so as to avoid friction interference between the clamping plate 3 and the bottom surface of the support platform 1.

[0038] In a preferred embodiment, the quick-release assembly includes symmetrically fixed snap-fit ​​strips 5 on the inner side of the movable upright plate 2, the snap-fit ​​strips 5 being arranged in a vertical direction; on the side of the clamping plate 3 near the movable upright plate 2, there are inverted U-shaped slots 6 symmetrically fixedly arranged corresponding to the snap-fit ​​strips 5, the snap-fit ​​strips 5 being able to snap into the interior of the corresponding U-shaped slots 6.

[0039] In order to ensure the stability of the engagement between the snap-fit ​​strip 5 and the U-shaped slot 6, a through strip slot 7 is provided on both sides of the snap-fit ​​strip 5. On the two corresponding sides inside the U-shaped slot 6, a strip-shaped snap post 8 is fixedly provided corresponding to the strip slot 7. When the U-shaped slot 6 and the snap-fit ​​strip 5 are assembled, the strip-shaped snap post 8 can be snapped into the inside of the strip slot 7 to ensure the stability of the engagement between the U-shaped slot 6 and the snap-fit ​​strip 5.

[0040] The quick-release assembly facilitates the replacement of clamping plate 3, which means that workpieces of different models can be clamped and fixed, making it highly practical.

[0041] In a preferred embodiment, two sets of locking components are provided corresponding to the two sets of movable upright plates 2 and clamping plates 3. The locking components include a rotating rod 9, an upright plate 10, a pressing rod 11, and a pressing column 12; wherein,

[0042] The rotating rod 9 has one end rotatably mounted at the center of the top surface of the clamping plate 3;

[0043] There are two upright plates 10, which are symmetrically fixed on the top surface of the movable upright plate 2.

[0044] A clamping rod 11 is positioned above the corresponding movable upright plate 2. One end of the clamping rod 11 is rotatably mounted on the upper part of the two corresponding upright plates 10. An L-shaped pressure plate 14 is fixedly mounted on the bottom surface of the end of the clamping rod 11 away from the upright plate 10. A through hole 15 is provided on the horizontal plate surface of the L-shaped pressure plate 14. A threaded hole 16 is provided on the top surface of the movable upright plate 2 corresponding to the through hole 15. A bolt 17 is provided through the through hole 15 and the threaded hole 16.

[0045] An abutment plate 18 is fixedly provided on the outer circumferential side of the bolt 17. A layer of anti-slip rubber is fixedly provided on the bottom surface of the abutment plate 18. The anti-slip rubber layer abuts against the top surface of the L-shaped pressure plate 14 after the bolt 17 passes through the through hole and bolt hole 16, so as to prevent the bolt 17 from loosening during the processing.

[0046] The clamping column 12 is set perpendicular to the bottom surface of the clamping rod 11 and is fixedly set on the bottom surface of the clamping rod 11 corresponding to the rotating rod 9, and is used to abut against the top surface of the rotating rod 9.

[0047] The driving mechanism includes two sets of driving components. Each set of driving components is disposed on the top surface of the support platform 1 and located on the outer side of the movable upright plate 2, and is used to drive the corresponding movable upright plate 2 to move on the top surface of the support platform 1.

[0048] The feeding mechanism is located on the top surface of the support platform 1, on one side of the clamping mechanism, and is used to push the workpiece located inside the clamping mechanism to the outside of the clamping mechanism.

[0049] The locking assembly ensures that after the workpiece is clamped and processed, the clamping plates 3 and the corresponding movable vertical plate 2 do not move vertically in the wall direction. This avoids instability when the workpiece is clamped by the clamping plates 3 and ensures the stability of the clamping mechanism.

[0050] In a preferred embodiment, the driving assembly includes a first driving cylinder 19 fixedly disposed on the top surface of the support platform 1. The piston rod of the first driving cylinder 19 is fixedly connected to the side of the corresponding movable upright plate 2 away from the clamping plate 3. Mounting rods 20 are symmetrically fixedly disposed on both sides of the first driving cylinder 19. A telescopic rod 21 is fixedly disposed on the side of the mounting rod 20 near the movable upright plate 2. The telescopic rod 21 is parallel to the length direction of the piston rod of the first driving cylinder 19, which is used to improve the stability when the corresponding movable upright plate 2 is moved by the first driving cylinder 19.

[0051] In a preferred embodiment, the feeding mechanism includes a mounting plate 22 fixedly disposed on the top surface of the support platform 1, located on one side of the clamping mechanism. A second driving cylinder 23 is fixedly disposed on the side of the mounting plate 22 near the clamping mechanism. The length direction of the piston rod of the second driving cylinder 23 is perpendicular to the direction of the linear guide rail 4. A U-shaped feeding plate 24 is fixedly disposed at the transmission end of the piston rod of the second driving cylinder 23. Rotating balls are embedded in the bottom surface of the U-shaped feeding plate 24 to improve the stability of the U-shaped feeding plate 24 during movement and reduce the friction between the U-shaped feeding plate 24 and the top surface of the support platform 1.

[0052] In a preferred embodiment, a plurality of limiting components are fixedly provided on the side of the clamping plate 3 away from the corresponding movable upright plate 2. The limiting components include strip-shaped inclined plates 25 symmetrically fixed on the plate surface of the clamping plate 3. The angle between the strip-shaped inclined plates 25 and the plate surface of the clamping plate 3 is set to 30-45°. The strip-shaped inclined plates 25 are arranged vertically on the plate surface of the clamping plate 3.

[0053] In addition, the placement position of the workpiece can be pre-drawn on the top surface of the support platform 1 between the two clamping plates 3 using a pen or adhesive tape, which can improve work efficiency.

[0054] The working principle of this utility model:

[0055] Multiple workpieces are placed on the top surface of the support platform 1 between two clamping plates 3. Then, the corresponding moving vertical plate 2 is driven by the first driving cylinder 19 to move towards each other along the direction of the linear guide rail 4, thereby realizing that the two clamping plates 3 move towards each other. Multiple sets of limiting components on the two clamping plates 3 limit and fix the workpieces, so as to achieve simultaneous clamping of multiple workpieces with consistent clamping force, thereby improving processing accuracy and processing efficiency.

[0056] After processing, the pneumatic second drive cylinder 23 drives the U-shaped feeding plate 24 to move multiple workpieces together to the outside of the clamping plate 3. This avoids manually removing the workpieces one by one if the temperature of the freshly processed workpieces is too high, thus preventing burns to the workers and improving work efficiency.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
