[0023] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1 and Figure 2As shown, a pneumatic shearing device with adjustable shearing position includes a bracket 1, a first lifting rod 2, a ball joint 3, a mounting plate 35, a pneumatic shear 4, a control box 5, a slide assembly 6, and a second telescopic rod 7. The bracket 1 is an inverted U-shaped frame. The bracket 1 includes a crossbeam 11 and two support legs 12. The crossbeam 11 is arranged horizontally. The two support legs 12 are connected to the two ends of the crossbeam 11 and support the crossbeam 11. The slide assembly 6 is connected to the crossbeam 11 and is arranged along the length of the crossbeam 11. The slide assembly 6 includes a slide rail 61, a slider 62, and a first locking bolt 63. The slide rail 61 is provided with a C-shaped groove and is arranged along the length of the crossbeam 11. The upper end of the slider 62 is T-shaped corresponding to the C-shaped groove. The slider 62 slides left and right in the C-shaped groove of the slide rail 61 through the T-shaped block at the upper end. The top end of the first lifting rod 2 is connected to the slider 62, so that when the slider 62 moves left and right, it drives the first lifting rod 2 to move left and right. The upper end of the T-shaped block of the slider 62 is threaded It is connected with a first locking bolt 63, and a slot hole 611 corresponding to the first locking bolt 63 is provided on the side of the slide rail 61. The slot hole 611 extends along the length direction of the slide rail 61, and the first locking bolt 63 passes through the slot hole 611. The head diameter of the first locking bolt 63 is larger than the inner diameter of the slot hole 611. When the first locking bolt 63 is tightened, the slider 62 is connected and tightened to the slide rail 61. When the slider 62 needs to be slid, the first locking bolt 63 is loosened, so that the first lifting rod 2 can be moved to the predetermined position and fixed at the predetermined position by tightening the first locking bolt 63.

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the top end of the first lifting rod 2 is connected to the slider 62. The first lifting rod 2 is arranged perpendicular to the crossbeam 11. The first lifting rod 2 includes multiple first telescopic sections 21. By providing multiple first telescopic sections 21, the first lifting rod 2 can be extended or shortened. Subject to the static friction between the multiple first telescopic sections 21, the first lifting rod 2 can be fixed in a predetermined position, which is convenient for height adjustment. The lower end of the first lifting rod 2 is connected to the second telescopic rod 7. The second telescopic rod 7 is perpendicular to the first lifting rod 2. The second telescopic rod 7 includes multiple second telescopic sections 71. The multiple second telescopic sections 71 can be extended or shortened. Subject to the static friction between the multiple second telescopic sections 71, the second telescopic rod 7 can be fixed in a predetermined position, which is convenient for adjusting the front-to-back distance.

[0026] like Figure 2As shown, the ball hinge joint 3 is connected to the front end of the second telescopic rod 7. The ball hinge joint 3 includes a ball seat 31, a ball 32, a rod body 33 and a second locking bolt 34. The rear end of the ball seat 31 is connected to the second telescopic rod 7. The front end of the ball seat 31 is provided with a accommodating cavity. The accommodating cavity is spherical as a whole for accommodating the ball 32. The ball 32 is movably connected to the ball seat 31. The rod body 33 is located outside the ball seat 31 and the rear end of the rod body 33 is connected to the ball 32, so that the ball 32 can be driven to rotate for universal adjustment. The second locking bolt 34 is provided on the side wall of the ball seat 31. One end of the second locking bolt 34 passes through the side wall of the ball seat 31 and enters the accommodating cavity. When the second locking bolt 34 is tightened, one end of the second locking bolt 34 is pressed against the ball 32 to fix the ball 32, thereby fixing the position of the rod body 33.

[0027] like Figure 2 、 Figure 3 and Figure 4 As shown, the back of the mounting plate 35 is connected to the front end of the rod body 33. The mounting plate 35 is provided with multiple mounting holes. The pneumatic shears 4 are detachably connected to the mounting plate 35 via connecting bolts. The pneumatic shears 4 use existing pneumatic shears, such as the Lili MS-V pneumatic shears with an operating pressure of 0.4-0.5 MPa. The pneumatic shears 4 are detachably connected to a shear head 41. Since the shear head 41 is detachably connected to the pneumatic shear body 4, it is convenient to replace different shear heads 41 according to different usage scenarios. Since the pneumatic shears 4 is connected to the ball joint 3 through the mounting plate 35, the position of the pneumatic shears 4 can be universally adjusted within a certain range through the ball joint 3 so that the scissor head 41 is oriented toward the desired angle. Since the second telescopic rod 7 can adjust the front and rear lengths, the pneumatic shears 4 can adjust the front and rear positions through the second telescopic rod 7, the first lifting rod 2 can adjust the height, the pneumatic shears 4 can adjust the up and down positions through the first lifting rod 2, the slider 62 can slide left and right, and the pneumatic shears 4 can adjust the left and right positions through the slide assembly 6, so that the left and right, up and down, front and back positions of the pneumatic shears 4 can all be adjusted, and the direction of the scissor head 41 can be universally adjusted within a certain range.

[0028] like Figure 1 and Figure 5As shown, the control box 5 is connected to the crossbeam 11 (it can also be connected to other parts of the bracket 1 as needed), and a solenoid valve 51 connected to the pneumatic shears 4 is provided in the control box 5. The solenoid valve 51 is connected to the external air source through an air source pipe. The solenoid valve 51 is connected to the pneumatic shears 4 through the air pipe so as to control the shearing work of the pneumatic shears 4. The solenoid valve 51 is electrically connected to the first switch 52, and the control box 5 is connected to the external power supply through a power cord. The control box 5 is also provided with existing components such as fuses, relays, and emergency stop buttons. The first switch 52 is connected to the relay in the control box 5. After the first switch 52 is turned on, the relay receives a signal and controls the operation of the solenoid valve 51. In this embodiment, the first switch 52 adopts an existing foot switch, such as the Changde Electric CFS-302 aluminum-plastic shell self-resetting foot switch. The first switch 52 is connected to the control box 5 through a cable. The cable is long enough to facilitate the placement of the first switch 52 in a specified position, such as Figure 5 As shown, when the device is placed on a workbench, the supporting legs 12 of the bracket 1 are fixed to the workbench surface by connecting bolts, and the first switch 52 is placed on the bottom surface under the workbench, so that the staff can use their feet to step on it, thereby controlling the cutting work of the pneumatic shears 4, freeing the staff's hands. The staff can operate the workpiece to be cut with both hands, approach the scissors head 41, step on the first switch 52 to carry out the cutting work, and after cutting, the staff will place the cut workpiece to the designated position and then take the next workpiece to be cut, which is highly efficient.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
