Technical Field

[0001] This utility model relates to the field of ultrasonic welding fixture technology, specifically an ultrasonic welding jig. Background Technology

[0002] An ultrasonic plastic welding machine is a machine that uses ultrasonic waves for welding. It is commonly used for welding plastics, completely replacing the traditional industry practice of using glue. During ultrasonic welding, there are no bolts, nails, clips, welding materials, or adhesives used to bond the materials together. It is faster than traditional adhesives or glues, dries faster, and the welding process can be easily automated and customized. Ultrasonic plastic welding machines offer various welding methods, such as fusion welding, riveting, and spot welding.

[0003] A novel ultrasonic plastic spot welding machine, with application number 202120022798.5, includes a spot welding machine body. A connecting column is provided on one side of the spot welding machine body, and a supporting cylinder is provided on one side of the connecting column. A fixing threaded hole is provided through the outer surface of one side of the supporting cylinder, and a fixing threaded post is provided inside the fixing threaded hole. A fixing plate is provided inside the supporting cylinder on one side of the fixing threaded post. A connecting shaft is provided outside the fixing threaded post on one side of the fixing plate, and a rubber block is provided on the outer surface of the other side of the fixing plate. A first limiting plate is provided below the connecting column on one side of the spot welding machine body, and a through hole is provided through the upper outer surface of the first limiting plate. This novel ultrasonic plastic spot welding machine is more convenient to handle and reduces noise during use, offering better application prospects. However, it is not convenient for longitudinally clamping and fixing two annular parts, nor is it convenient for rotating and adjusting the welding head, thus affecting welding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for ultrasonic welding, which solves the problems in the prior art where it is inconvenient to clamp and fix two annular parts longitudinally and it is inconvenient to rotate and adjust the welding head, thus affecting the welding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic welding fixture, comprising a workpiece positioning seat, an arc-shaped workpiece clamping groove on the upper side of the workpiece positioning seat, a movable clamping plate on the inner wall of the arc-shaped workpiece clamping groove via a first cylinder, a welding adjustment seat on one side of the workpiece positioning seat, a first slider inside the welding adjustment seat via a first lead screw, a second slider on the upper side of the first slider via a vertical plate and a second lead screw, a transverse support arm on one side of the second slider, a limiting end seat rotatably provided at one end of the transverse support arm via a connecting shaft, and an ultrasonic welding machine and a welding head inside the limiting end seat via a lifting bracket and a cylinder.

[0006] Furthermore, the lower end of the movable clamping plate is an arc-shaped clamping plate, and the lower wall of the movable clamping plate is slidably disposed with the inner wall of the arc-shaped workpiece clamping groove.

[0007] Furthermore, the first lead screw is an X-axis lead screw, and the second lead screw is a Z-axis lead screw.

[0008] Furthermore, both the first lead screw and the second lead screw include a lead rod disposed in a slide groove, and one end of the lead rod is connected to a servo motor.

[0009] Furthermore, the second cylinder is fixedly mounted on the outer wall of the limiting end seat, and the lifting bracket is slidably mounted through the inner wall of the limiting end seat.

[0010] Furthermore, a motor is connected between the transverse support arm and the connecting shaft via a gear set, and the motor is fixedly installed outside one end of the transverse support arm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has an arc-shaped workpiece clamping groove on the workpiece positioning seat, and a movable clamping plate is provided on the inner wall of the arc-shaped workpiece clamping groove through a first cylinder. The lower end of the movable clamping plate is an arc-shaped clamping plate, and the lower wall of the movable clamping plate is slidably arranged with the inner wall of the arc-shaped workpiece clamping groove. This allows the movable clamping plate to be moved laterally by the first cylinder, so that the two annular parts to be welded can be clamped and fixed longitudinally. Moreover, the clamping and fixing stability is high, which is beneficial to improving the welding accuracy.

[0013] 2. In this utility model, the welding adjustment seat is equipped with a first slider through a first lead screw.

One end of the horizontal support arm is equipped with an ultrasonic welding machine and a welding head through a connecting shaft, a limiting end seat, a lifting bracket and a cylinder. This allows the welding head to be driven to move and adjust along the X-axis and Z-axis through the first lead screw and the second lead screw, thereby meeting the welding needs of different horizontal positions or heights and improving welding efficiency.

[0014] 3. In addition, the present invention has a limiting end seat at one end of the transverse support arm via a connecting shaft. The transverse support arm and the connecting shaft are connected by a motor through a gear set, and the motor is fixedly installed outside one end of the transverse support arm. This allows the longitudinal rotation adjustment of the welding head to be achieved by driving the connecting shaft to rotate forward and backward through the motor and gear set. This facilitates the rotational welding of the inner side of the annular or arc-shaped welding parts, further improving the welding efficiency. Attached Figure Description

The lower end of the movable clamping plate 3 is an arc-shaped clamping plate, and the lower wall of the movable clamping plate 3 is slidably disposed with the inner wall of the arc-shaped workpiece clamping groove 2. This allows the movable clamping plate 3 to be moved laterally by the first cylinder 4 for adjustment, which can longitudinally clamp and fix the two annular parts to be welded. Moreover, the clamping and fixing stability is high, which is beneficial to improving the welding accuracy.

[0022] like Figure 1 and Figure 3As shown, in order to adjust the movement of the welding head 16 along the X-axis and Z-axis, a welding adjustment seat 5 is also provided on one side of the workpiece positioning seat 1. Inside the welding adjustment seat 5, a first slider 7 is provided via a first lead screw 6. A second slider 10 is provided on the upper side of the first slider 7 via a vertical plate 8 and a second lead screw 9. The first lead screw 6 is an X-axis lead screw, and the second lead screw 9 is a Z-axis lead screw.

This allows the welding head 16 to be moved and adjusted along the X-axis and Z-axis by the first lead screw 6 and the second lead screw 9. Furthermore, the distance between the welding head 16 and the limiting end seat 12 can be adjusted by the second cylinder 14, thereby meeting the requirements for different radial rotation welding applications and welding applications at different lateral positions or heights, thus improving welding efficiency.

[0023] like Figure 1 and Figure 2 As shown, in order to adjust the longitudinal rotation of the welding head 16, a motor 18 is connected between the transverse support arm 11 and the connecting shaft 17 via a gear set 19. The motor 18 is fixedly installed outside one end of the transverse support arm 11, so that the connecting shaft 17 can be adjusted to rotate forward and backward by the motor 18 and the gear set 19, thereby facilitating the rotational welding of the inner side of the annular or arc-shaped weldment and further improving the welding efficiency.

[0024] The working principle and usage process of this utility model are as follows: When in use, the two arc-shaped or ring-shaped workpieces to be welded are placed in the arc-shaped workpiece clamping groove 2 on the upper part of the workpiece positioning seat. The movable clamping plate 3 is adjusted laterally by the first cylinder 4, which can clamp and fix the two ring-shaped parts to be welded longitudinally. Then, the welding head 16 is adjusted along the X-axis and Z-axis by the first lead screw 6 and the second lead screw 9, so as to meet the welding use of different lateral positions or heights and facilitate the improvement of welding efficiency.
