Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and to a welding device that facilitates the replacement of welding head components. Background Technology

[0002] The welding head assembly of traditional welding equipment is directly mounted on a fixed frame. When replacing it, due to the lack of an effective limiting structure, it is impossible to quickly ensure that the rack on the welding head surface of the welding head assembly is kept in a horizontal position. As a result, when installing the left and right slider positioning mechanism, the left and right sliders and the welding head surface cannot be precisely matched. This requires repeated rotation of the entire welding head assembly for adjustment, which makes the adjustment difficult and inefficient. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a welding device that facilitates the replacement of welding head assemblies. The device includes a fixed frame, a welding base mechanism, and a welding head assembly. Both the welding head assembly and the welding base mechanism are fixedly mounted on the fixed frame. The welding base mechanism has a left slider positioning mechanism and a right slider positioning mechanism positioned opposite each other, located on opposite sides of the welding head surface of the welding head assembly. The device also includes a boom clamp base, a welding head node pad, and a clamping support. The boom clamp base is fixedly mounted on the fixed frame via a pad. The top of the boom clamp base has an arc-shaped groove that mates with the welding head assembly. An installation hole is formed within the arc-shaped groove. The welding head node pad is fixedly installed within the installation hole. The welding head assembly is placed horizontally on the welding head node pad and is fixedly connected to the boom clamp base via positioning pins and screws. The clamping support is sleeved on the welding head assembly and fixedly connected to the boom clamp base via screws.

[0004] Furthermore, the welding head node pad has two limiting holes, which are located on both sides of the welding head assembly. Limiting pins are inserted into the limiting holes and fit against the side wall of the welding head assembly.

[0005] Furthermore, the clamping support is provided with two first positioning pin holes, and the top of the amplitude rod clamp base is provided with two second positioning pin holes. The two second positioning pin holes are located on both sides of the arc groove and correspond to the two first positioning pin holes respectively. The first positioning pin holes and the second positioning pin holes are connected by positioning pins.

[0006] Furthermore, a node support mechanism is also installed on the fixed frame. The node support mechanism is located at the end of the welding base mechanism away from the base of the amplitude rod clamp. The top of the node support mechanism is provided with a slot that cooperates with the welding head assembly, and the welding head assembly is engaged in the slot.

[0007] Furthermore, the left slider positioning mechanism includes a connecting seat and a left slider. The connecting seat is slidably mounted on the welding base mechanism via a driving cylinder, and the sliding direction is towards or away from the welding head surface. The left slider is mounted on the end of the connecting seat near the right slider positioning mechanism via a fixing screw. The right slider positioning mechanism includes a mounting seat and a right slider. The mounting seat is slidably mounted on the welding base mechanism via a pressing cylinder, and the sliding direction is vertical. The right slider is slidably mounted on the mounting seat via a driving cylinder, and slides out of the mounting seat to contact the left slider or retracts into the mounting seat when driven by the driving cylinder. The side of the left slider and the mounting seat that are close to each other, and the bottom surface of the right slider and the mounting seat that are in sliding contact with each other, together with the welding head surface, form a clamping space for fixing the wire harness.

[0008] Furthermore, the left slider, the mounting base, the right slider, and the welding head surface are all provided with racks on one side of the clamping space. The racks on the left slider and the mounting base extend to their bottom and top surfaces, respectively. The rack on the bottom surface of the left slider slides into contact with the rack on the welding head surface, and the rack on the right slider slides into contact with the rack on the top surface of the mounting base.

[0009] Furthermore, the left slider is slidably connected to the connecting seat, and the sliding direction is vertical. The connecting seat is provided with a strip-shaped through hole, and the left slider is provided with a threaded hole. The size of the strip-shaped through hole is larger than that of the threaded hole, and the fixing screw passes through the strip-shaped through hole and is threadedly connected to the threaded hole.

[0010] Beneficial effects: 1. In this utility model, the design of the luffing rod clamp base, welding head node pad, and clamping support allows for convenient and quick positioning and fixing of the welding head assembly during replacement. This ensures that the rack on the welding head surface is horizontally positioned, reducing the difficulty of debugging the left and right slider positioning mechanisms during installation and assembly, and improving the efficiency of welding head assembly replacement. Specifically, the welding head node pad is first fixedly installed in the mounting hole within the arc-shaped groove, ensuring that the top of the welding head node pad is horizontal. Then, the welding head assembly is installed into the arc-shaped groove, making the bottom support plane of the welding head assembly fit against the top of the welding head node pad. Next, the lateral positions of the welding head assembly and the luffing rod clamp base are fixed using positioning pins and ferrules. The vertical positions of the welding head assembly and the luffing rod clamp base are fixed using clamping supports and screws. Finally, the assembly of the luffing rod clamp base and the welding head assembly is fixedly installed in the corresponding position on the fixed frame.

[0011] 2. In this utility model, the setting of two limiting holes and two limiting pins can further limit the left and right position of the welding head assembly, ensuring that the welding head assembly is in the center of the arc groove; the setting of two first positioning pin holes, two second positioning pin holes and two positioning pins can facilitate the positioning of the clamping support and the base of the amplitude rod clamp, which is convenient for subsequent screw installation and fixing.

[0012] 3. In this utility model, the node support mechanism and the slot can further facilitate the limiting and fixing of the welding head assembly, and at the same time provide auxiliary support for the welding head assembly, thereby improving the stability of the connection between the welding head assembly and the fixed frame.

[0013] 4. In this utility model, the connection seat, left slider, mounting seat, right slider, and the rack sliding connection ensure the stability of the relative movement between the left slider and the welding head surface, and between the right slider and the mounting seat. The sliding connection between the left slider and the connection seat facilitates the disassembly and assembly of the left slider. Combined with the strip-shaped through hole and the threaded hole and the size limitation between them, the relative position of the left slider and the welding head surface along the axis of the welding assembly can be appropriately adjusted, thereby ensuring the precise fit between the rack on the left slider and the rack on the welding head surface.

[0024] In this embodiment, the configuration of the amplitude rod clamp base 4, the welding head node pad 5, and the clamping support 6 allows for convenient and quick positioning and fixing of the welding head assembly 3 during replacement. This ensures that the rack on the welding head surface is horizontally positioned, reducing the difficulty of debugging the positioning mechanisms of the left slider 15 and the right slider 18 during installation and improving the replacement efficiency of the welding head assembly 3. Specifically, the welding head node pad 5 is first fixedly installed in the mounting hole 8 within the arc-shaped groove, ensuring that the welding head node pad 5... The top is horizontal. Then, the welding head assembly 3 is installed into the arc-shaped groove so that the support plane at the bottom of the welding head assembly 3 is in contact with the top of the welding head node pad 5. Next, the left and right positions of the welding head assembly 3 and the luffing rod clamp base 4 are limited and fixed by the positioning pin 9 and the M6 ​​kimming screw. The up and down positions of the welding head assembly 3 and the luffing rod clamp base 4 are limited and fixed by the clamping support 6 and the M6 ​​screw. Finally, the assembly of the luffing rod clamp base 4 and the welding head assembly 3 is fixedly installed in the corresponding position of the fixed frame 1.

[0028] In this embodiment, the arrangement of two first positioning pin holes, two second positioning pin holes, and two positioning pins 12 facilitates the positioning of the clamping support 6 and the luffing rod clamp base 4, making it easier to install and fix the screws later.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2As shown, a node support mechanism 13 is also installed on the fixed frame 1.

[0032] In this embodiment, the sliding connection between the left slider 15 and the connecting seat 14 facilitates the assembly and disassembly of the left slider 15. Combined with the strip-shaped through hole and the threaded hole, as well as the size limitation between them, the relative position of the left slider 15 and the welding head surface along the axial direction of the welding assembly can be appropriately adjusted, thereby ensuring that the rack on the left slider 15 and the rack on the welding head surface are precisely matched.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
