Description

Technical Field

[0001] This utility model belongs to the field of positioning structure technology, specifically relating to an ultrasonic welding fixture positioning structure. Background Technology

[0002] Ultrasonic welding fixtures (also known as ultrasonic molds or jigs) are specialized devices used to fix and position welded parts and transmit vibration energy, ensuring welding quality by providing a stable support structure. Ultrasonic welding fixtures generally consist of three parts: a welding head, a base mold, and a support frame. The welding head requires precise positioning, typically achieved through a positioning structure used on ultrasonic welding equipment.

[0003] The existing tooling welding head and bottom mold do not have a positioning structure to control the rotation of the welding head relative to the bottom mold. The bottom mold is positioned on the welding table through pin holes on the bracket. The angle of the welding head relative to the bottom mold can only be identified by the naked eye. If the angle is deviated, it will affect the welding quality. If a welding machine is compatible with multiple sets of welding positioning tooling and the tooling is frequently changed, the angle of the welding head must be manually rotated repeatedly for calibration. This results in multiple calibration operations, which are cumbersome and may not even achieve accurate calibration results. This affects the convenience and accuracy of the positioning structure for ultrasonic welding tooling positioning. Therefore, this utility model proposes an ultrasonic welding tooling positioning structure. Utility Model Content

If the angle is deviated, it will affect the welding quality. If a welding machine is compatible with multiple sets of welding positioning fixtures and the fixtures are frequently changed, the angle of the welding head needs to be manually rotated repeatedly for calibration, which results in cumbersome calibration operations and may even fail to achieve accurate calibration results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic welding fixture positioning structure, comprising a positioning structure body, the positioning structure body including a support frame and a welding head, the support frame having fixing holes at both ends and a threaded hole at the top end, and the positioning structure body further comprising:

[0006] A quick positioning mechanism, comprising a positioning component disposed at the connection between the support frame and the welding head, wherein both ends of the inner side of the positioning component are provided with fitting components, and the bottom end of the positioning component is provided with a fixing mounting component;

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: an ultrasonic welding fixture positioning structure, including a positioning structure body 100, the positioning structure body 100 including a support frame 101 and a welding head 102, the support frame 101 having fixing holes at both ends, and the support frame 101 having an internal threaded hole at its top end, and the positioning structure body 100 also having:

[0026] The quick positioning mechanism includes a positioning component located at the connection between the support frame 101 and the welding head 102. Both ends of the inner side of the positioning component are provided with fitting components, and the bottom end of the positioning component is provided with a fixing installation component. The welding head 102 can be pre-installed with the welding equipment, and the quick positioning mechanism can accurately position the welding head 102 to achieve quick replacement.

[0027] In order to facilitate the precise positioning and installation of the welding head 102 by means of the positioning component, in this embodiment, preferably, the positioning component includes a bottom mold 1021 fixedly installed on the upper surface of the support frame 101. A positioning block 1022 is provided on one side of the bottom mold 1021. After the bottom mold 1021 is fixedly installed, the positioning block 1022 is closed and fixed with the bottom mold 1021. The welding head 102 is positioned and installed by the positioning block 1022. The positioning block 1022 is only used during the equipment mold changing process and does not participate in the welding process.

[0028] To facilitate the bonding and installation of the positioning block 1022 and welding head 102 with the bottom mold 1021 using the bonding assembly, in this embodiment, preferably, the bonding assembly includes two positioning bonding surfaces 1026 integrally formed on one inner end of the positioning block 1022, and the surface of the positioning bonding surface 1026 is in close contact with the surface of the welding head 102. The positioning block 1022 and the welding head 102 are bonded, installed, and positioned using the positioning bonding surfaces 1026. Two fixing bonding surfaces 1027 are formed on the other inner end of the positioning block 1022, and the surface of the fixing bonding surface 1027 is in close contact with the surface of the bottom mold 1021. The side of the positioning block 1022 is bonded and fixedly installed with the surface of the bottom mold 1021 again using the fixing bonding surfaces 1027.

[0029] In order to facilitate the positioning of the positioning block 1022 on one side of the bottom mold 1021 by means of a fixed installation component, in this embodiment, preferably, the fixed installation component includes through holes 1024 at both ends of the bottom of the positioning block 1022, and fixing bolts 1023 are engaged inside the through holes 1024. The bottom mold 1021 has internal threaded holes 1025 at both ends of one side, so that the positioning block 1022 can be attached to the side of the bottom mold 1021 by means of a fixed contact surface 1027. The fixing bolts 1023 pass through the inside of the through holes 1024 and are screwed into the inside of the internal threaded holes 1025 for fixed installation.

[0030] The support engagement mechanism includes fixed support components at both ends of the inner surface of the positioning component. The top of the fixed support component is provided with a precision engagement component. When the positioning block 1022 is supported and positioned, the positioning block 1022 is stably supported and fixedly positioned by the support engagement mechanism, which is less prone to instability and provides more stable positioning.

[0031] To facilitate the stable support and repositioning of the positioning block 1022 after installation, the fixed support assembly preferably includes a fixed base plate 1011 at both ends of the upper surface of the bottom mold 1021. Fixing screws 1012 are provided at the edges of the fixed base plate 1011, and the fixed base plate 1011 is fixedly connected to the surface of the bottom mold 1021 by the fixing screws 1012. A support rod 1013 is integrally provided at the middle position of the upper surface of the fixed base plate 1011. The fixed base plate 1011 and the support rod 1013 can be fixedly installed on the top of the bottom mold 1021 by the fixing screws 1012, thereby facilitating the stable installation and support of the support rod 1013.

[0032] To facilitate precise support and positioning of the positioning block 1022 during fixed installation using a precision engaging assembly, in this embodiment, preferably, the precision engaging assembly includes a locking head 1014 integrally disposed at the top of the support rod 1013. The surface of the locking head 1014 is integrally provided with an anti-friction annular cover 1016. Two positioning locking holes 1015 are formed at the top of the inner surface of the positioning block 1022. The locking head 1014 and the interior of the positioning locking holes 1015 are tightly connected by the anti-friction annular cover 1016. The locking head 1014 can be engaged inside the positioning locking holes 1015 by the anti-friction annular cover 1016, thereby stably supporting and fixing the positioning block 1022 with precise positioning by supporting it with the support rod 1013.

[0033] In this invention, the positioning block 1022 is made of a metal material with high hardness or other non-metallic material with high rigidity, and the positioning block 1022 must not be deformed during use.

[0034] The working principle and usage process of this utility model: When using this ultrasonic welding fixture positioning structure, the lower surface of the support frame 101 can contact the fixed installation position on the surface of the workbench, and the mounting bolt can be inserted into the workbench through the internal hole of the fixing bolt to fix the positioning structure body 100. This can make the positioning structure body 100 more stable and accurate in positioning operation.

[0035] Then, when the welding head 102 is pre-assembled onto the welding equipment, directly attach the surface of the fixing mating surface 1027 to the side of the bottom mold 1021, loosen the mounting bolts controlling the rotation of the welding head 102, visually ensure that the welding head 102 is parallel to the bottom mold 1021, lower the welding head 102 to the height range marked on the positioning block 1022, screw the fixing bolt 1023 through the through hole 1024 into the internal thread hole 1025 to fix the positioning block 1022, manually rotate the welding head 102 to make it fit with the positioning mating surface 1026 on the positioning block 1022, and then lower the welding head 102 again. The top of 2 is fixed to the top of the equipment with mounting bolts, thus fixing the welding head 102 on the equipment. The fixing bolts 1023 and the positioning block 1022 used for fixing are removed, and the installation and positioning of the positioning fixture are completed in one go without repeated correction. After that, appropriate welding parameters can be selected to start the normal use of the welding equipment. This makes it more convenient to use one welding machine with multiple sets of welding positioning fixtures and to frequently change the positioning installation, thereby reducing equipment investment, reducing production debugging time, reducing production costs, and improving the convenience and accuracy of positioning the welding head 102 by the main body of the positioning structure 100.

[0036] Finally, when the positioning structure body 100 is used for positioning and installation, the support rod 1013 is first fixedly installed on the upper surface of the bottom mold 1021 by the fixed base 1011. When the positioning block 1022 is installed, the clamping head 1014 is engaged in the positioning clamping hole 1015 by the anti-friction annular cover 1016, so that the positioning block 1022 is supported and engaged. Therefore, when the side of the welding head 102 contacts the surface of the positioning block 1022 through the positioning contact surface 1026, the positioning block 1022 is stably supported before positioning and installation, and then the bottom end is fixed. When the positioning block 1022 is under fixed installation and the welding head 102 is positioned and installed on the side of the positioning block 1022, or when the thread structure of the fixing bolt 1023 is damaged due to frequent rotation and becomes slightly loose, the support rod 1013 and the clamp 1014 provide stable support for the positioning block 1022. The positioning contact surface 1026 on the inner surface of the positioning block 1022 provides stable contact and precise positioning for the welding head 102. This improves the stability and positioning accuracy of the positioning structure body 100 in supporting and reinforcing the positioning block 1022 when the welding head 102 is positioned.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
