Spacers 82 are fixed to both sides of the machine bracket 81. The inner surface of the pad 82 is curved to hold the welding device 5 tightly against the support structure 8.

The ultrasonic welding machine further comprises a first pushing device 3 for limiting the welding width of the welding head and a second pushing device 4 for providing a downward pressure at the welding head. The first pushing device 3 and the second pushing device 4 are both mounted on the main body mounting block 2.

Fig. 3 is a schematic view of a main body mounting block. As shown in fig. 3, a main body mounting block 2 is fixed to the front end of the machine base plate 1. The main body mounting block 2 includes a first mounting block 204 and a second mounting block 206 fixed to the left and right sides of the horn of the welding device 5. The horn is placed in a mounting area 208 between the first mounting block 204 and the second mounting block 206. The mounting plate 203 is fixed to the rear side of the first mounting block 204. A translational fixing seat 35 is fixed above the mounting plate 203. Below the mounting plate 203 is a translator slider base 33 fixed above the machine base plate 1. The translating pusher 32 moves back and forth under the mounting plate 203. The mounting plate 203 is provided with a through hole, and the shift lever 343 passes through the through hole of the mounting plate 203 to rotate left and right. A partition plate 207 is fixed beside the mounting plate 203 for separating the first pushing device 3 and the second pushing device 4. A third mounting block 202 is fixed to the partition plate 207 opposite to the second mounting block 206. The up-down slider 43 slides up and down between the second mounting block 206 and the third mounting block 202. A through groove is formed below the second mounting block 206. The up-down push rod 42 slides back and forth in the through groove.

Fig. 4 is a schematic view of the first pushing device. As shown in fig. 4, the first pushing means 3 comprise a translation slider base 33 fixed above the machine base plate 1. The pan pusher 32 is slidably mounted in a slide slot in a pan slide base 33. The translation pushing block 32 is driven by the first cylinder 31 and can move back and forth in a sliding groove in the translation sliding block base 33. An inclined limiting groove is formed on the upper surface of the translation pushing block 32. The limiting groove is not parallel to the moving direction of the translational push block 32, and the limiting groove can be formed along the diagonal line of the translational push block 32.

The first pushing device 3 further comprises a toggle mechanism 34 and a translational fixed seat 35. A through hole is formed on the translation fixing seat 35. Fig. 5 is a schematic view of a toggle mechanism. As shown in fig. 5, the toggle mechanism 34 includes a left and right moving block 341, a traverse block 344, and a toggle lever 343. The lower surface of the left and right moving blocks 341 is fixed with a positioning pin. The positioning pin slides in the slide groove, and the left and right moving blocks 341 move accordingly. The shift lever 343 passes through a through hole in the translational fixing base 35. One end of the shift lever 343 is rotatably fixed to the left and right moving blocks 341 via a first shaft 345. The other end of the shift lever 343 is rotatably fixed to the traverse block 344 via the second shaft 342. The lateral shift block 344 is slidably mounted in the translational fixed seat 35. The shaft of the shift lever 343 is rotatably fixed to the inner wall of the through hole in the translational fixing base 35 through the third shaft 346.

The first cylinder 31 drives the translation thrust block 32 to slide forward in a slide slot in the translation slider base 33. Because the limit groove is formed along the diagonal line of the translational push block 32, the positioning pin on the lower surface of the left and right moving blocks 341 slides to the first end of the limit groove, which is relatively located on the left side. The left moving block 341 slides leftward to drive one end of the shift lever 343 to slide leftward, and the shaft of the shift lever 343 rotates in the through hole of the translational fixing seat 35, so that the other end of the shift lever 343 moves rightward relatively, and pushes the transverse moving block 344 to slide rightward on the translational fixing seat 35, approaching the welding head. The first air cylinder 31 drives the translation push block 32 to slide backwards in the sliding groove in the translation sliding block base 33, and the process is reversed, and the transverse moving block 344 slides leftwards on the translation fixing seat 35 in the direction away from the welding head. The lateral shift 344 may be closer to or farther from the horn for limiting the weld width of the horn.

Fig. 6 is a schematic view of a second pushing device. As shown in fig. 6, the second pushing device 4 includes an up-down slider 43 and an up-down push rod 42 which is moved back and forth on the machine base plate 1 by a second cylinder 41. The vertical surfaces of the upper and lower push rods 42 are provided with inclined sliding through holes. The up-down slider 43 is provided with a rotation through hole. The roller is positioned in the sliding through hole to roll and two ends of the roller penetrate through the rotating through hole. The top end of the upper and lower sliding blocks 43 is fixed with a right push-pull block 45. The right push-pull block 45 is slidably provided with a parallel push-pull block 47. A right push-pull block spring seat 46 is fixed on one side of the right push-pull block 45. A spring 48 is mounted between the right push-pull block 45 and the right push-pull block spring seat 46. A strap 44 is also included. Fig. 7 is a schematic view of the mounting of the strap. Referring to fig. 7, one end of the strap 44 is fixed to the body mounting block 2. The other end of the strap 44 is secured to a parallel push-pull block 47.

When the second cylinder 41 retracts to drive the up-down push rod 42 to move to the first position on the horizontal plane, the roller rolls to the top end of the sliding through hole, the up-down slider 43 is pushed to the position located above, the right push-pull block 45 is pushed upwards, one end of the belt 44 is fixed to the main body mounting block 2 and is kept fixed, the other end of the belt 44 is fixed to the parallel push-pull block 47 and moves upwards along with the parallel push-pull block, the belt 44 is tensioned, the parallel push-pull block 47 is pulled towards the direction close to the right push-pull block spring seat 46, and the spring 48 is compressed. When the second cylinder 41 pushes outward, the process is reversed, the strap 44 is released, the spring 48 springs out, and the parallel push-pull block 47 is pushed out away from the right push-pull block spring seat 46. After the right push-pull block spring seat 46 is pushed out, the right push-pull block spring seat is positioned right above the welding head, so that the vertical space position of the welding head can be limited when welding is carried out, and downward pressure is applied to the welding position.

As shown in fig. 1, the device further comprises a first limiting device 6 and a second limiting device 7. The first stop 6 is mounted below the mounting plate 203. The first limiting device 6 limits the moving range of the translational push block 32. A through hole is formed below the third mounting block 202. The second limiting device 7 is arranged in the through hole. The second limiting device 7 limits the moving range of the upper and lower push rods 42. The first stop means 6 and the second stop means 7 are of the same construction. Fig. 8 is a schematic view of a spacing device. Fig. 9 is a cross-sectional view of the spacing device. Taking the first position-limiting device 6 as an example, as shown in fig. 8 and 9, the position-limiting device includes a housing 61 and a screw 62 penetrating into the housing 61. One end of the screw 62 is screwed into the stopper 63. The other end of the screw 62 is fitted with a knob 64. Rotation of the knob 64, and therefore the lead screw 62, rotates the stop block 63 into or out of the housing to limit the range of movement of the associated structure.
