Description

High frequency plastic spin welding jig Technical Field The invention relates to the technical field of ultrasonic welding of plastic products, in particular to a high-frequency plastic spin welding jig. Background In the field of plastic product manufacture, injection molded parts are often required to be mutually assembled and achieve a sealing effect so as to meet product performance and use requirements. For tubing plastic products, such as respiratory tubing assemblies in medical devices, it is often necessary to connect and secure a plurality of injection molded components. Currently, the assembly methods commonly used in the industry mainly include two structures, namely a snap connection and a screw fixation. However, these conventional means of assembly have significant limitations, on the one hand, in that the snap-fit or screw-fit arrangement is difficult to achieve in certain elongated pipe products due to the size and internal structure of the product, and on the other hand, conventional mechanical means of attachment tend to be difficult to achieve the desired sealing effect for products having sealing requirements, thereby affecting the overall performance and reliability of the product. In view of the above problems, ultrasonic welding technology is introduced into the field of plastic product assembly. Ultrasonic welding is to transfer high-frequency vibration waves to the surfaces of two objects to be welded, and under the condition of pressurization, the surfaces of the two objects are rubbed with each other to form fusion between molecular layers. Spin welding is a special form of ultrasonic welding, particularly suitable for welding operations on round or tubular plastic products. However, in actual production, it is found that for high-frequency spin welding operation of long-tube products, due to lack of a special positioning jig, the products are easy to displace or rotate in the welding process, so that problems of welding position deviation, poor sealing and the like are caused, and the product quality and the production efficiency are seriously affected. Therefore, development of a fixture specially suitable for spin welding of high-frequency plastic is needed to solve the problems of accurate positioning and reliable fixation of long-tube products in the spin welding process. Disclosure of Invention The invention aims to provide a high-frequency plastic spin welding jig for solving the problems of accurate positioning and reliable fixation of long tube products in the spin welding process. In order to achieve the above purpose, the following technical scheme is adopted: the high-frequency plastic spin welding jig comprises an upper die and a base, wherein two ends of the top of the base are respectively connected with a left cushion block and a right cushion block, the top of the left cushion block is also connected with a left clamping block, the top of the right cushion block is also connected with a clamping driving assembly, the clamping driving assembly is also in driving connection with a right clamping block, the left clamping block and the right clamping block are oppositely arranged, the top of the base is positioned at one side of the left cushion block and is also connected with a fixing block, the upper die is arranged above the left clamping block and the right clamping block, the bottom of the upper die is also connected with a placing block, and the bottom of the placing block is provided with a placing groove.
