Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling technology and relates to a modular ultrasonic welding tooling for electric vehicle tail boxes. Background Technology
[0002] The tail box of an electric vehicle, as an integral part of the vehicle, serves a storage function. Existing electric vehicle tail boxes are typically made of plastic or metal. Therefore, the components of the tail box require welding. Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, forming a fusion between molecular layers. Welding requires the assistance of welding fixtures. Existing welding fixtures have the following drawbacks:
[0003] The tooling consists of a base fixture, which can only limit the lower contour of the tail box. Due to the unevenness of the upper and lower contours and structure of the tail box, it cannot achieve effective clamping.
[0004] The tooling is in a fixed position and requires manual assembly work under the ultrasonic welding head, which is somewhat dangerous.
[0005] Based on the above, we designed a modular ultrasonic welding fixture for electric vehicle tail boxes. Summary of the Invention
[0006] The purpose of this invention is to provide a modular ultrasonic welding fixture for electric vehicle tail boxes to solve the problems mentioned in the background art.
[0007] The objective of this utility model can be achieved through the following technical solution: a modular ultrasonic welding fixture for electric vehicle tail boxes, comprising a fixture carrier plate and a tail box limiting block. The tail box limiting block is installed on one side of the top of the fixture carrier plate. A lower pressing tongue plate is provided on the inner side of the tail box limiting block. A tail box fixing seat is installed on the other side of the top of the fixture carrier plate. An electric cylinder mounting seat is installed on the top of the side wall of the tail box fixing seat. An electric cylinder is installed inside the electric cylinder mounting seat. The output end of the electric cylinder passes through the electric cylinder mounting seat and is connected to a pressure block connecting strip. A pressure block part is fixedly installed at the end of the pressure block connecting strip. A universal ball seat is installed at the top of the electric cylinder. A movable connecting rod is installed at the universal ball of the universal ball seat. A spring clamp is fixedly installed at one end of the movable connecting rod.
[0008] The aforementioned modular ultrasonic welding fixture for electric vehicle tail boxes also includes a linear track and a track slide. The sidewall of the linear track has a track groove, and the track slide slides linearly along the linear track via the track groove. The track slide is integrally formed with the fixture carrier plate. This design allows the fixture carrier plate to slide linearly along the linear track under the traction of the track slide plate, facilitating better transfer of the fixture carrier plate to the area below the ultrasonic welding head. This provides good operational safety and avoids the assembly work performed below the ultrasonic welding head as in existing solutions.
[0009] In the aforementioned modular ultrasonic welding fixture for electric vehicle tail boxes, a fixing screw is installed on the side of the universal ball joint. The fixing screw passes through the universal ball of the universal ball joint and limits its movement. This design aims to limit and lock the universal ball of the universal ball joint, ensuring that the movable connecting rod can be fixed in position after adjustment in any direction, thereby guaranteeing the firmness and stability of the spring clamp holding the electric vehicle tail box.
[0010] In the aforementioned modular electric vehicle tail box ultrasonic welding fixture, the top of the tail box limiting block has a circular hole, inside which a pin is installed. An elliptical through hole is formed on the side wall of the pin, and a positioning pin is fitted inside the elliptical through hole. A pin channel is formed on the side wall of the circular hole, and the pin is inserted into the pin channel with its end corresponding to the end of the pin channel. This design further presses and limits the tail box portion located between the tail box limiting block and the lower pressing tongue plate, ensuring the tail box portion is securely installed between them without detachment, while also providing good ease of disassembly.
[0011] In the aforementioned modular ultrasonic welding fixture for electric vehicle tail boxes, an adjustment slot is provided at the bottom of the side wall of the tail box fixing seat, and the pressure block connecting strip moves up and down inside the adjustment slot. This design allows for better adjustment of the vertical height of the pressure block connecting strip, thereby accommodating electric vehicle tail box components of different thicknesses and increasing the clamping range of the tail box fixing seat.
[0012] Compared with the prior art, the advantages of this modular ultrasonic welding fixture for electric vehicle tail boxes are as follows: a universal ball seat is installed at the top of the electric cylinder, and a movable connecting rod is installed at the universal ball of the universal ball seat. A spring clamp is fixed at one end of the movable connecting rod. This allows the movable connecting rod to be adjusted according to any position of the universal ball of the universal ball seat, thereby better responding to the contour of the tail box, maintaining the stability and firmness of the clamping, and ensuring multi-directional limiting, so that the electric vehicle tail box has good positional accuracy during the welding process.
[0013] By setting a linear track bar and a track sliding seat, the side wall of the linear track bar is provided with a track groove, and the track sliding seat slides linearly along the linear track bar through the track groove. The track sliding seat is integrally formed with the fixture carrier plate. This allows the fixture carrier plate to slide linearly along the linear track bar under the traction of the track sliding seat, which facilitates better transfer of the fixture carrier plate to the area below the ultrasonic welding head. This provides good operational safety and avoids the assembly operation below the ultrasonic welding head in existing solutions. Attached Figure Description

[0021] Among them, such as Figure 1 As shown, in order to prevent the pressure block connecting strip 9 and the pressure block part 6 from being interfered with by the structure of the tail box fixing seat 5 during the movement, an adjustment slot 8 is provided at the bottom of the side wall of the tail box fixing seat 5, and the pressure block connecting strip 9 moves up and down inside the adjustment slot 8.
[0022] By using the tail box limiting block 7, the tail box fixing seat 5, and the elastic clamp 14, the three parts of the electric vehicle tail box are clamped and limited, which can better cope with the contour parts of the tail box, maintain the stability and firmness of the clamping, and make the electric vehicle tail box have good positional accuracy during the welding process.
[0023] Example 2: The tooling includes a fixture carrier plate 4 and a tail box limiting block 7. The tail box limiting block 7 is installed on one side of the top of the fixture carrier plate 4. A lower pressing tongue plate 16 is provided on the inner side of the tail box limiting block 7. A tail box fixing seat 5 is installed on the other side of the top of the fixture carrier plate 4. An electric cylinder seat 10 is installed on the top of the side wall of the tail box fixing seat 5. An electric cylinder 11 is installed inside the electric cylinder seat 10.
