Specific embodiments

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0016] Embodiment: As Figures 1-3 shown, the present invention provides an adjustable tooling for card plate welding, including a fuselage 1. Symmetrically distributed jig tables 2 are provided directly above the fuselage 1. The bottom ends of the jig tables 2 are fixedly provided with moving tables 21. The lower surfaces of the moving tables 21 are fixedly provided with driving blocks 22. Ball screws 23 are threadedly inserted into the driving blocks 22. The upper surfaces of the moving tables 21 are fixedly provided with lower clamping plate seats 24. Upper clamping plate seats 31 are provided inside the jig tables 2. Lifting rods 3 are fixedly provided at the top ends of the upper clamping plate seats 31. The top ends of the lifting rods 3 slidably penetrate through the top ends of the jig tables 2.

[0017] On one side of the fuselage 1, there are mirror-distributed mounting grooves 4. Scale rulers 41 are fixedly arranged in the mounting grooves 4. At one end of the mounting groove 4 away from the scale ruler 41, a protective plate 42 is fixedly arranged. Pointer 43 is fixedly arranged on the outer wall of one side of the moving platform 21. By setting the protective plate 42 of the mounting groove 4, the effect of protecting the scale ruler 41 can be achieved, preventing the scale ruler 41 from being damaged.

[0018] Fixed seats 210 are rotatably arranged at both ends of the ball screw 23. The bottom end of the fixed seat 210 is fixedly installed on the outer upper surface of the fuselage 1. By setting the fixed seat 210, the effect of fixing the ball screw 23 can be achieved, enabling the ball screw 23 to rotate stably.

[0019] Drive rods 220 are fixedly arranged at one end of the ball screw 23. One end of the drive rod 220 penetrates through one side wall of the fixed seat 210 and is placed outside. A turning handle 230 is fixedly arranged at the end of the drive rod 220 away from the ball screw 23.

[0020] Hydraulic cylinders 310 are arranged at the top ends of the lifting rods 3. The driving ends of the hydraulic cylinders 310 are fixedly installed coaxially with the corresponding lifting rods 3.

[0021] Guide blocks 5 are fixedly arranged at the bottom ends of the moving platforms 21 in a mirror distribution. Linear rails 51 are slidably inserted at the bottoms of the guide blocks 5. The bottom ends of the linear rails 51 are fixedly installed on the outer upper surface of the fuselage 1. By setting the guide blocks 5 and the linear rails 51, the effect of limiting the moving platform 21 can be achieved, enabling the moving platform 21 to move stably.

[0022] Symmetrically distributed limiting rods 320 are fixedly arranged at the top ends of the upper clamping plate seats 31. The tops of the limiting rods 320 slide through the top ends of the fixture tables 2 and are placed outside. By setting the limiting rods 320, the effect of limiting the upper clamping plate seats 31 can be achieved, enabling the upper clamping plate seats 31 to move up and down stably.

[0023] The protective plate 42 is made of transparent glass material. By setting the protective plate 42 as transparent glass material, the staff can observe the scale ruler 41.

[0024] Working principle: First, according to the length of the leaf spring clamping plate, the driving handle 230 is driven to drive the driving rod 220 to rotate. The driving rod 220 drives the ball screw 23 to rotate. During the rotation of the ball screw 23, the driving block 22 is driven to move. The driving block 22 drives the moving table 21 to move. The moving table 21 drives the fixture table 2 to move. At the same time, the pointer 43 is driven to move during the movement of the moving table 21. The staff observes the moving distance of the fixture table 2 and the moving table 21 through the pointer 43 and the scale 41. When the fixture table 2 and the moving table 21 move to a position convenient for accurately positioning the leaf spring clamping plate, the driving force on the handle 230 is removed. The two ends of the leaf spring clamping plate are placed on the lower clamping plate seat 24. The hydraulic cylinder 310 is started. The hydraulic cylinder 310 drives the lifting rod 3 to move downward. The lifting rod 3 drives the upper clamping plate seat 31 to move downward. When the upper clamping plate seat 31 moves downward to a position where the leaf spring clamping plate can be fixed, the hydraulic cylinder 310 is closed. The two ends of the leaf spring clamping plate are fixed by the upper clamping plate seat 31 and the lower clamping plate seat 24. Subsequently, the staff can weld the leaf spring clamping plate.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
