[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0028] The following is combined with Figure 1-4 This application is described in further detail.
[0029] refer to Figure 1-3 The high-precision push block adjustment mechanism shown in the figure is easy to operate, including: a mounting seat 1, a pressure block 2, an adjustment component 3 and a locking component 4, the pressure block 2, the adjustment component 3 and the locking component 4 are all arranged on the mounting seat 1, one end of the pressure block 2 is a pressure head, and the pressure head extends to the outside of the mounting seat 1, the adjustment component 3 is used to make the pressure block 2 slide toward the outside of the mounting seat 1 or slide toward the inside of the mounting seat 1, and the locking component 4 is used to limit the sliding of the pressure block 2, so that when the pressure block 2 needs to be adjusted, the locking component 4 releases the restriction on the pressure block 2, and then the pressure block 2 is slid toward the outside of the mounting seat 1 or slides toward the inside of the mounting seat 1 (adjusting the distance between the pressure head and the mounting seat 1) through the adjustment component 3 until the pressure head and the ultrasonic welding head are at a suitable distance (such as the above-mentioned 0.03mm-0.05mm), and then the position of the pressure block 2 is locked again through the locking component 4 to limit the sliding of the pressure block 2, so as to complete the adjustment of the pressure block 2 to adapt to the welding work of different terminal welding heads.
[0030] refer to Figure 2-3The cam 31 is provided with a screw rod 31 and a movable seat 32. The screw rod 31 is rotatably arranged on the mounting seat 1. One end of the screw rod 31 extends to the outside of the mounting seat 1 and is provided with a hand wheel 9. The movable seat 32 is sleeved on the screw rod 31 and is threadedly connected to the screw rod 31. The mounting seat 1 is provided with a limiting groove 11, and the movable seat 32 is clamped in the limiting groove 11 (limiting the movement of the movable seat 32 so that the movable seat 32 can only move along the axial direction of the screw rod 31). In the actual production process, a pressure block slide groove is provided on one side of the limiting groove 11, and the pressure block 2 is slidably arranged in the pressure block slide groove. The axial direction of the screw rod 31 is consistent with the sliding direction of the pressure block 2. A connecting seat 33 is provided on one side of the movable seat 32, and a bayonet 21 is provided on the pressure block 2. The connecting seat 33 is arranged in the bayonet 21. In this way, the screw rod 31 is conveniently rotated by the hand wheel 9 to make the movable seat 32 move along the axial direction of the screw rod 31, so as to achieve the purpose of adjusting the sliding of the pressure block 2.
[0031] Further optimization is that Figure 4 As shown, in order to further improve the accuracy, a ball-end screw 5 is provided on the connecting seat 33, and the end of the ball-end screw 5 is in contact with the side of the bayonet 21 away from the pressure head. The tail of the ball-end screw 5 is flush with the connecting seat 33, and the ball of the ball-end screw 5 protrudes from the connecting seat 33. After the pressure block 2 is installed, the ball is in a compressed state, which can effectively avoid the assembly gap between the pressure block 2 and the connecting seat 33, and also provide a certain pre-tightening force for the pressure block 2 to prevent the pressure block 2 from being offset during the locking process of the locking assembly 4.
[0032] Further optimization is that Figure 2 and Figure 3 As shown, a spring 6 is sleeved on the screw rod 31, and the spring 6 is arranged on the side of the moving seat 32 close to the pressure head. The spring 6 is always in a compressed state within the effective stroke, which can effectively avoid the radial gap between the moving seat 32 and the screw rod 31, so that the moving seat 32 is always on one side of the gap.
[0033] like Figure 1-Figure 3As shown, the locking assembly 4 includes a U-shaped plate 41, a squeeze block 42 and an adjusting member 43. The U-shaped plate 41 is arranged at the bottom of the pressing block 2, and the squeeze block 42 is installed in the U-shaped plate 41 through the adjusting member 43. The adjusting member 43 is used to drive the squeeze block 42 to move, so that the opening of the U-shaped plate 41 becomes larger or smaller; the mounting seat 1 is provided with a cover plate 7 on the top surface of the pressing block 2, and the adjusting member 43 is a screw. The adjusting member 43 passes through the squeeze block 42 and is rotatably connected with the squeeze block 42 (the end surfaces of the squeeze block 42 close to both sides of the U-shaped plate 41 are inclined surfaces or curved surfaces), and the adjusting member 43 is threadedly connected with the U-shaped plate 41. The mounting seat 1 is provided with an adapter screw operation hole, and the screw is rotated through the mounting hole. In this way, when it is necessary to lock the pressure block 2, the adjusting piece 43 is rotated to make the squeezing block 42 move toward the inside of the U-shaped plate 41, so that the two sides of the U-shaped plate 41 are opened outward, so that one side of the U-shaped plate 41 located above the squeezing block 42 is upwardly abutted against the bottom of the pressure block 2, and forms a clamp with the cover plate 7, so that the position of the pressure block 2 is locked. When it is necessary to release the restriction on the pressure block 2, the adjusting piece 43 is rotated in the opposite direction, and the squeezing block 42 is away from the U-shaped plate 41, so that the two sides of the U-shaped plate 41 move inward, so as to release the restriction on the pressure block 2.
[0034] It is further optimized that, in order to facilitate the repair and maintenance of the present application, the cover plate 7 is connected to the mounting seat 1 by bolts, so that the cover plate 7 can be easily removed.
[0035] Further optimization is that Figure 1 and Figure 2 As shown, in order to facilitate adjustment by the staff, a scale 8 is provided on the top surface of the pressing block 2. When the pressing block 2 slides, the pressing block 2 can be adjusted by referring to the scale 8.
[0036] In summary, when the pressure block 2 needs to be adjusted, the locking assembly 4 releases the restriction on the pressure block 2, and then the pressure block 2 is slid toward the outside of the mounting seat 1 or toward the inside of the mounting seat 1 through the adjustment assembly 3 (adjusting the distance between the pressure head and the mounting seat 1) until the pressure head and the ultrasonic welding head are at an appropriate distance (such as the above-mentioned 0.03mm-0.05mm), and then the position of the pressure block 2 is locked again through the locking assembly 4 to limit the sliding of the pressure block 2, thereby completing the adjustment of the pressure block 2 to adapt to the welding work of different terminal welding heads.
[0037] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
