Description

Technical Field

[0001] This application relates to the field of ultrasonic welding technology, and in particular to an anti-loosening pressure block structure. Background Technology

[0002] Ultrasonic welding utilizes the mechanical vibration energy of ultrasonic frequencies to transfer the vibration energy to the surface of the metal or non-metal materials to be welded. Through the mutual friction of the material surfaces, the molecular layers fuse together.

[0003] In related technologies, the pressure block of ultrasonic welding is connected to the housing by sliding a slider. After the slider position is adjusted to the correct position, the pressure block is used to press down on the substrate and limit its position.

[0004] In ultrasonic welding, the aforementioned pressure block may loosen and retract during production, causing it to collide with the welding head or increasing the gap between them, resulting in poor welding, affecting the welding effect, and reducing welding quality. Summary of the Invention

[0005] To address the issue of pressure block loosening and retraction during ultrasonic welding, which can lead to collisions between the pressure block and the welding head or increased gaps between them, resulting in poor welding, reduced welding quality, and compromised welding performance, this application provides an anti-loosening pressure block structure. The structure comprises a housing with a groove. A slider matching the groove is slidably connected within the groove. The slider extends out of the housing, and the pressure block is mounted on the slider. The housing also includes a limiting unit for positioning the slider and a sliding unit for driving the slider to move.

[0006] In one specific implementation, the limiting unit includes a clamping block, a placement groove is provided on the groove wall of the slide, the clamping block slides in the placement groove, a first inclined surface is provided on the surface of the clamping block facing the slider, a second inclined surface matching the first inclined surface is provided on the surface of the slider facing the clamping block, a pushing assembly is provided on the housing to push the clamping block to make the first inclined surface and the second inclined surface contact, and a limiting assembly is provided on the housing for limiting the clamping block.

[0007] In one specific implementation, the push assembly includes a mounting hole in the housing, with a mating bolt threaded into the mounting hole, and the mating block abutting between the mating bolt and the slider.

[0008] In one specific implementation, the outer edge of the clamping bolt is threaded with a clamping nut that matches the clamping bolt, and the clamping nut has a flange ring on its surface facing the slider, and the end face of the flange ring facing the slider contacts the housing.

[0009] In one specific implementation, the limiting component includes two mounting slots formed at the bottom of the placement slot, and the two mounting slots are provided with limiting posts that match the mounting slots. The abutting block is located between the two limiting posts and is in contact with both limiting posts. Both limiting posts are located between the abutting bolt and the slider.

[0010] In one specific implementation, the sliding unit includes a lead screw that passes through and is rotatably connected to the housing, with one end of the lead screw passing through and threadedly connected to the slider.

[0011] In one specific implementation, a knob is fixedly fitted onto the end of the lead screw away from the slider.

[0012] In one specific implementation, a limiting groove is formed at the bottom of the slider, and a limiting block that matches the limiting groove is provided on the slider, with the limiting block slidably connected within the limiting groove.

[0013] In one specific implementation, the slider has two stops on its surface facing the pressure plate, and the pressure block is located between the two stops and in contact with each of the two stops.

[0014] In one specific implementation, a sealing plate is slidably connected to the surface of the housing facing the pressure block, and the slider passes through the sealing plate.

[0015] In summary, this application has at least the following beneficial technical effects: under ultrasonic welding conditions, the position of the slider in the groove is adjusted by the sliding unit, thereby realizing the adjustment of the slider and the pressure block position. The position of the slider is limited by the limiting unit, so the slider is not prone to significant movement, reducing the possibility of pressure block position deviation during high-frequency vibration, and improving the stability of the pressure block in the welding production process.

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses an anti-loosening pressure block structure.

[0021] Reference Figure 1 and Figure 2 The anti-loosening pressure block structure includes a housing 1, on which a groove 2 is formed. A slider 3, matching the size of the groove 2, is slidably connected within the groove 2. The top portion of the slider 3 extends out of the housing 1, and a pressure block 18 is bolted to the slider 3. The housing 1 is provided with a limiting unit for limiting the slider 3 and a sliding unit for driving the slider 3 to slide. Two stops 16 are fixedly connected to the surface of the slider 3 facing the pressure plate. The pressure block 18 is located between the two stops 16 and contacts both stops 16. The two stops 16 limit the position of the pressure block 18, reducing the possibility of the pressure block 18 shaking under ultrasonic welding conditions and improving the stability of the pressure block 18 installed on the slider 3.

[0022] Reference Figure 1 and Figure 2 A limiting groove 14 is provided at the bottom of the slider 3. A limiting block 15 matching the size of the limiting groove 14 is fixedly connected to the slider 3. The limiting block 15 is slidably connected within the limiting groove 14. The limiting groove 14 limits the position of the limiting block 15, reducing the possibility of the slider 3 moving horizontally during movement and improving the stability of the slider 3. A sealing plate 17 is slidably connected to the surface of the housing 1 facing the pressure block 18. The slider 3 passes through the sealing plate 17. The sealing plate 17 protects the slide groove 2 and reduces the possibility of external impurities falling into the slide groove 2.

[0023] Reference Figure 1 and Figure 2 The limiting unit includes a clamping block 5. A placement groove 4 is provided on the groove wall of the slide groove 2. The clamping block 5 slides in the placement groove 4. A first inclined surface is provided on the surface of the clamping block 5 facing the slider 3. A second inclined surface 6 matching the size of the first inclined surface is provided on the surface of the slider 3 facing the clamping block 5. A pushing component is provided on the housing 1 to push the clamping block 5 to make the first inclined surface and the second inclined surface 6 contact. A limiting component for limiting the clamping block 5 is provided on the housing 1.

[0024] Therefore, the push assembly is activated, pushing the clamping block 5 towards the slider 3, so that the first inclined surface and the second inclined surface 6 come into contact with each other and press against each other. The two small-angle inclined surfaces 6, the first and second inclined surfaces, cooperate to lock each other, thereby locking the slider 3 and preventing it from moving backward and loosening, thus achieving the anti-vibration locking function and further improving the stability of the slider 3 and the pressure block 18 during the ultrasonic welding process.

[0025] Reference Figure 1 and Figure 2The push assembly includes a mounting hole 7 on the housing 1. A locking bolt 8, matching the size of the mounting hole 7, is threaded into the mounting hole 7. A locking block 5 is pressed between the locking bolt 8 and the slider 3. A locking nut 9, matching the size of the locking bolt 8, is threaded onto the outer edge of the locking bolt 8. In this embodiment, the locking nut 9 is a non-metallic nut. A flange ring 10 is fixedly connected to the surface of the locking nut 9 facing the slider 3. The end face of the flange ring 10 facing the slider 3 contacts the housing 1. The flange ring 10 increases the contact area between the end face of the locking nut 9 and the housing 1, further improving the anti-loosening effect of the locking nut 9. Therefore, rotating the locking bolt 8 causes one end of the locking bolt 8 facing the locking block 5 to push the locking block 5 to move, causing the first inclined surface to fit against the second inclined surface 6. The locking nut 9 enhances the anti-loosening effect, reduces the possibility of the locking bolt 8 shaking, and improves the stability of the locking bolt 8.

[0026] Reference Figure 1 and Figure 2 The limiting component includes two mounting slots formed at the bottom of the placement slot 4. Each mounting slot contains a limiting post 11 matching the size of its mounting slot. The clamping block 5 is located between and in contact with both limiting posts 11. Both limiting posts 11 are located between the clamping bolt 8 and the slider 3. In this embodiment, the limiting posts 11 can specifically be high-density, high-hardness pins. The clamping block 5 and the limiting posts 11 are tightly fitted together, combining rolling friction and sliding friction, resulting in low resistance. The two limiting posts 11 limit the position of the clamping block 5, reducing the possibility of positional deviation and preventing the clamping block 5 from being moved by the slider 3, thus improving the stability of the clamping block 5's position.

[0027] Reference Figure 1 and Figure 2 The sliding unit includes a lead screw 12 that passes through and is rotatably connected to the housing 1. The end of the lead screw 12 facing the slider 3 passes through the slider 3 and is threadedly connected to it. In this embodiment, both the lead screw 12 and the slider 3 are fitted with fine threads, specifically M8*1.0 fine threads. This increases the effective thread length and makes their fit tighter, reducing play between the mating threads. A knob 13 is fixedly fitted onto the end of the lead screw 12 away from the slider 3. The knob 13 is easy for the operator to grip, thus improving the convenience of adjusting the position of the slider 3. Therefore, by rotating the lead screw 12, the operator moves the slider 3 along the length of the lead screw 12, thereby adjusting the position of the slider 3 inside the housing 1.

[0028] The implementation principle of this application embodiment is as follows: Under ultrasonic welding conditions, the operator rotates the lead screw 12, causing the slider 3 to move along the length of the lead screw 12, thereby adjusting the position of the slider 3 inside the housing 1. After adjusting to the required position, the operator rotates the clamping bolt 8, causing the clamping bolt 8 to push the clamping block 5 to move towards one end of the clamping block 5, so that the first inclined surface and the second inclined surface 6 come into contact with each other and abut against each other. The two small-angle inclined surfaces 6 of the first inclined surface and the second inclined surface 6 cooperate with each other to lock the slider 3, thereby locking the slider 3 and preventing the slider 3 from moving backward and loosening, achieving the anti-vibration locking function. Finally, the clamping nut 9 is tightened, so that the clamping nut 9 and the clamping bolt 8 are interlocked to prevent loosening, which further improves the stability of the slider 3 and the pressure block 18 in the ultrasonic welding process. The slider 3 is not prone to obvious movement, reducing the possibility of the pressure block 18 shifting position during high-frequency vibration, and improving the stability of the pressure block 18 in the welding production process.
