Technical Field
[0001] The present application relates to the technical field of welding jigs, and in particular to a horn clamping structure. Background Art
[0002] Ultrasonic welding is a welding device whose working principle is as follows: the ultrasonic welding machine converts electric current into high-frequency electrical energy, which is converted into mechanical motion of the same frequency through a transducer. The mechanical motion is then transmitted to the mold through a set of amplitude-changing horn devices. The mold transfers the received vibration energy to the joint area of the workpiece to be welded. In this area, the vibration energy is converted into heat energy through friction, melting the plastic and realizing welding.

[0028] Reference Figure 1 as well as Figure 2 A horn clamping structure includes a mounting base 1, a transducer assembly 2 inserted through the mounting base 1, a horn assembly 3, and an upper mold 4 mounted on the horn assembly 3. A first positioning connector 5 is disposed between the mounting base 1 and the horn assembly 3, and a second positioning connector 6 for use with an ultrasonic welding machine is disposed on one side of the mounting base 1. The first positioning connector 5 allows the horn assembly 3 to be quickly mounted and positioned on the mounting base 1, while the second positioning connector 6 allows the mounting base 1 to be quickly mounted and positioned on the ultrasonic welding machine, thereby ensuring assembly accuracy and efficiency.
[0029] Specifically, the fixing base 1 is vertically arranged, and the fixing base 1 has an adapter hole 11 for cooperating with the installation of the amplitude transformer assembly 3. The axis of the adapter hole 11 is vertically arranged, and the amplitude transformer assembly 3 is passed through and installed in the adapter hole 11. The upper end of the amplitude transformer assembly 3 is connected to the transducer assembly 2, and the lower end of the amplitude transformer assembly 3 is connected to the upper mold 4.
[0030] The first positioning connection base 5 includes a first positioning member 51 that is sleeved within the adapting hole 11, and a positioning locking member 52. The horn assembly 3 passes through and abuts the inner ring of the first positioning member 51. The positioning locking member 52 abuts the outer ring of the first positioning member 51 and is connected to the fixed base 1. In this embodiment, the diameter of the first positioning member 51 gradually increases from top to bottom, with the upper end of the first positioning member 51 being the small end and the lower end being the large end. In other words, the first positioning member 51 is tapered, and the adapting hole 11 is also tapered to match the shape of the first positioning member 51. Accordingly, the horn assembly 3 includes a horn and a positioning ring 31 sleeved on the horn. The positioning ring 31 can be fixedly connected to the horn or detachably connected to the horn. The positioning ring 31 has positioning protrusions 311, which are respectively located above and below the positioning ring 31, so that the positioning protrusions 311 can abut or disengage with the large end and small end of the first positioning member 51. The positioning locking member 52 is used to lock and fix the horn and the positioning switch. The positioning locking member 52 abuts the large end and is threadedly connected to the fixing seat 1.
[0031] By configuring the first positioning connection base 5 in this manner, when the horn assembly 3 needs to be installed in the fixing base 1, the first positioning member 51 is first sleeved and installed in the adapting hole 11, and then the horn is installed so that the positioning protrusions 311 of the positioning ring 31 abut against the large and small ends of the first positioning member 51. Under the action of the positioning protrusions 311, the horn is now positioned, that is, the axis of the horn coincides with the axis of the adapting hole 11. Finally, the positioning locking member 52 is installed and mounted to the fixing base 1 via a threaded connection. Under the limit of the positioning locking member 52, the horn and the positioning ring 31 can be accurately installed and fixed in the fixing base 1.
[0032] Reference Figure 2 、 Figure 3 as well as Figure 4The second positioning connection seat 6 is located on one side of the fixed seat 1. The second positioning connection seat 6 includes a positioning chuck 61 and a positioning Latin disk 62 provided on the positioning chuck 61. One end of the positioning Latin disk 62 is connected to the fixed seat 1, and the other end of the positioning Latin disk 62 is connected to the positioning chuck 61. Specifically, in order to conveniently connect with the fixed seat 1, one side of the positioning Latin disk 62 is provided with a plurality of connecting columns 621 that cooperate with the positioning chuck 61. The fixed seat 1 is provided with holes for cooperating with the connecting columns 621. The connecting columns 621 are passed through these holes and are aligned and connected to the fixed seat 1. The positioning Latin disk 62 and the fixed seat 1 can be conveniently aligned and connected through the connecting columns 621. A positioning column 622 for cooperating with the positioning chuck 61 is provided on the other side of the positioning Latin disk 62. Accordingly, the positioning chuck 61 includes a chuck base 611 and a chuck positioning cover 612 provided on the chuck base 611. The chuck positioning cover 612 has a positioning hole 6122 cooperating with the positioning Latin disk 62, and the positioning column 622 is passed through and connected to the positioning hole 6122.
[0033] The chuck positioning cover 612 also includes several chuck protrusions 6123, and the positioning dial 62 includes positioning grooves 623 that engage with the chuck protrusions 6123. The chuck protrusions 6123 engage or disengage with the positioning grooves 623. By providing the chuck protrusions 6123, the positioning chuck 61 can be aligned and installed simply by engaging the chuck protrusions 6123 with the positioning grooves 623 of the positioning dial 62. To facilitate alignment with an ultrasonic welder, the chuck positioning cover 612 includes several connecting positioning blocks 6121 that cooperate with the ultrasonic welder. By connecting the connecting positioning blocks 6121, the chuck positioning cover 612 can be quickly installed and engaged in the ultrasonic welder.
