AI Technical Summary
During the clamping process of existing sheet metal parts, due to excessive pressure on both sides, the mid-end of the workpiece is raised and deformed, making it difficult to cut.
A cutting fixture for sheet metal processing is designed, which combines a clamping mechanism and a pressing mechanism. The clamping mechanism achieves uniform clamping of the workpiece through the movable seat, locking bolts and elastic components. The pressing mechanism exerts downward pressure on the middle part of the workpiece by pressing the arc plate to prevent deformation.
It effectively prevents sheet metal parts from deforming due to excessive force during the clamping process, ensuring the stability and accuracy of the cutting process.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.
[0021] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.
[0022] See also Figures 1 to 4In this embodiment, a cutting fixture for sheet metal processing is provided, including a mounting seat 1, a slide groove 2 is provided above the mounting seat 1, a clamping mechanism 3 is symmetrically slidably connected inside the slide groove 2, the clamping mechanism 3 includes a moving seat 31, a locking bolt 32 is threadedly connected above the moving seat 31, a clamping mechanism 4 is connected to one side of the upper end of the locking bolt 32, the clamping mechanism 4 includes a connecting rod 41, one end of the connecting rod 41 is fixedly connected to the upper end of the locking bolt 32, and the other end of the connecting rod 41 is provided with a clamping arc plate 44, and the distance from the outer surface of the clamping arc plate 44 to the straight line where the center of the connecting rod 41 is located gradually increases.
[0023] When in use, the workpiece is placed on the mounting base 1, and the user moves the moving base 31 so that the moving base 31 is located on both sides of the workpiece. The moving base 31 is positioned by rotating the locking bolts 32, and the workpiece is limited on both sides by the moving base 31. At the same time, the locking bolts 32 are rotated by the connecting rod 41 to reduce the force required by the user when using it. When the workpiece needs to be tightened, the connecting rod 41 is rotated to the top of the workpiece when the locking bolts 32 are rotated, and the end with a larger distance from the outer surface of the tightening arc plate 44 to the straight line where the center of the connecting rod 41 is located gradually approaches the workpiece through the tightening arc plate 44, thereby tightening the middle part of the workpiece.
[0024] In further embodiments, see Figure 2 A pressing plate 34 is slidably connected to one side of the moving seat 31, and an elastic member 35 is fixedly connected to one side of the pressing plate 34. A cam 33 is fixedly connected to the outer side of the lower end of the locking bolt 32, and the cam 33 is located on one side of the elastic member 35. The locking bolt 32 is pressed on the mounting seat 1 when rotating, so as to keep the moving seat 31 positioned on the mounting seat 1. The locking bolt 32 drives the cam 33 to rotate during the rotation process, and the rotation of the cam 33 pushes the elastic member 35 to deform. The deformation force of the elastic member 35 pushes the pressing plate 34 to move outward, so that the pressing plate 34 clamps the workpiece.
[0025] In further embodiments, see Figure 3 The distance between the clamping arc plate 44 and the connecting rod 41 is adjustable. The outer side of the connecting rod 41 is threadedly connected with an internal thread sleeve 42. One side of the internal thread sleeve 42 is rotatably connected with a rotating block 43. One end of the rotating block 43 is fixedly connected to one end of the clamping arc plate 44. A long thread is provided on the outer side of the connecting rod 41. During the rotation of the internal thread sleeve 42, the position of one end of the internal thread sleeve 42 and the connecting rod 41 is changed, thereby changing the position of the clamping arc plate 44, so that the clamping position can be selected according to the style of different workpieces. Multiple short threads are provided on the outer side of the connecting rod 41, so that the thread sleeve 42 can be adjusted within multiple commonly used ranges, so that the internal thread sleeve 42 does not need to be rotated too many times during the adjustment process, so that it is convenient to use and adjust.
[0026] In a further embodiment, a plurality of parallel and staggered anti-slip strips are provided on the outer surface of the clamping arc plate 44. The square slip strips can increase the relative friction between the clamping arc plate 44 and the workpiece during the clamping process, thereby increasing the clamping force of the clamping arc plate 44.
[0027] In further embodiments, see Figure 4 An arc-shaped reinforcing rib is provided between the inner side of the pressing arc plate 44 and the rotating block 43. The reinforcing rib increases the supporting strength of the rotating block 43 on the arc plate 44, thereby providing a higher pressing force on the pressing arc plate 44.
[0028] In a further embodiment, the cross section of the slide groove 2 is "T"-shaped, and a "T"-shaped slider matching the slide groove 2 is fixedly connected below the moving seat 31. The moving seat 31 is kept from deflecting and swaying during the sliding process, and the stability during the movement is maintained.
[0029] In further embodiments, see Figure 1 A rubber pad 5 is fixedly connected between the slide grooves 2 inside the mounting seat 1, and the upper end surface of the rubber pad 5 is flush with the upper end surface of the mounting seat 1. The rubber pad 5 can increase the friction between the workpiece and the mounting seat 1, so that when the workpiece is placed, the clamping position can be better positioned. At the same time, when the locking bolt 32 rotates and moves downward, the lower end of the locking bolt 32 will also squeeze the rubber pad 5 to be concave and deformed, thereby increasing the friction between the locking bolt 32 and the rubber pad 5, making the positioning of the moving seat 31 more secure.
[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
