Description

Technical Field

[0001] This utility model relates to the field of clamping and positioning technology for thermoformed partition boards, specifically a thermoformed partition board hot riveting positioning fixture. Background Technology

[0002] In modern industrial production, thermoformed partition panels are widely used in electronics, medical devices, automobile manufacturing, and other fields due to their excellent physical properties and processing characteristics. Hot riveting, a key technology in the assembly of thermoformed partition panel components, melts the plastic at the connection points through heating and then applies pressure to solidify the parts, achieving a firm connection. To ensure the accuracy and strength of the hot riveting points, positioning fixtures are indispensable equipment in hot riveting operations; their performance directly affects the assembly quality and production efficiency.

[0003] However, with the increasing integration and structural complexity of industrial products, thermoformed partition panels are showing a trend towards larger sizes, smaller components, and greater quantity. Existing positioning fixtures exhibit numerous insurmountable technical bottlenecks when dealing with such products. On the one hand, due to the large size of thermoformed partition panels and the presence of many small parts, the single-point or single-area fixing methods used by traditional positioning fixtures are insufficient for achieving rapid and accurate positioning of each small part. Operators need to spend a significant amount of time adjusting the position of each small part and repeatedly calibrating the fixing state, resulting in a substantial increase in clamping time per setup and severely hindering production. According to industry statistics, when processing complex thermoformed partition panels, the clamping time of traditional fixtures can account for more than 40% of the total production time, greatly reducing overall processing efficiency.

[0004] On the other hand, the lack of versatility in existing tooling is particularly prominent. Most positioning tooling is designed only for specific models or size ranges of vacuum-formed partition panels, and its fixing structure and positioning parameters are relatively fixed. When companies need to produce products of different specifications, they often need to purchase or modify tooling equipment, which not only increases equipment procurement costs and maintenance expenses, but also causes production interruptions due to frequent equipment replacement and debugging, resulting in extended production cycles and increased labor costs.

[0052] Base plate 10: The base plate of the fixing component, which is fixedly connected to the sliding block 2 and is used to support the hinge cover 11 and form the bottom support of the fixing cavity 12;

[0054] Fixed cavity 12: A closed space enclosed by a base plate 10 and a hinged cover 11, with a form pad 13 installed inside for fixing the blister packing partition;

[0055] Form pad 13: An adaptable support component inside the fixing cavity, designed for isolation plates of different specifications, fixed by slots or adhesive, providing a precise support surface;

[0056] Base plate 14: The main structure of the mating locking component 5, made of hard metal material, used to install and fix the pin 15 and provide locking support;

[0059] Second unit docking hole 17: The hole on the second unit fixing component 4 corresponds to the other two sets of fixing pins 15 and is used for plugging and fixing when locked.

[0060] Working Principle: In the pre-positioning stage, the operator first assigns the thermoformed partition pieces to the first unit fixing assembly 3 and the second unit fixing assembly 4 according to their structural characteristics. Both sets of fixing assemblies adopt an openable structure design with a base plate 10 and a hinged cover 11. By folding the hinged cover 11 upwards, the internal fixing cavity 12 can be exposed. For partition pieces of different shapes, the operator can pre-install matching pads 13 in the fixing cavity 12. These pads are fixed by specially designed slots or adhesive methods, which can closely fit the contour of the partition piece and provide a stable support surface. Then, the partition piece is placed on the pads, and the hinged cover 11 is pressed down, using the closed space formed by it and the base plate 10 to initially fix the partition piece. This dual-station parallel pre-positioning mode can process multiple small pieces at the same time, greatly shortening the clamping time. After pre-positioning is completed, the movement mechanism of the sliding block 2 on the high-precision slide rail 1 begins to function. Two sets of parallel main limiting blocks 6 on the high-precision slide rail 1 form a snap-fit ​​guide structure with the main groove 7 at the bottom of the sliding block 2. The precise machining dimensions of the main limiting blocks 6 ensure that the sliding block 2 can only move in the straight line of the slide rail, effectively avoiding lateral deviation. At the same time, the cooperation design between the inner groove 8 of the slide rail and the anti-detachment block 9 on the sliding block 2 ensures the flexibility of sliding while preventing the sliding block 2 from accidentally detaching from the slide rail. The operator pushes the sliding block 2, causing the first and second unit fixing components 3 and 4 installed on it to slide towards each other along the slide rail until the two sets of components approach and complete docking. When the dual unit fixing components 3 and 4 slide to the predetermined position, the docking locking component 5 starts the locking procedure. The base plate 14 of the docking locking component 5 is made of high-strength hard metal material, which has good rigidity and wear resistance. The four sets of fixing pins 15 vertically arranged on it correspond precisely with the first unit docking holes 16 and the second unit docking holes 17 on the first and second unit fixing components 3 and 4. The operator places the base plate 14 close to the two sets of fixing components and, through manual pressing or mechanical drive, inserts the four sets of fixing pins 15 into the first unit's mating holes 16 and the second unit's mating holes 17, respectively. Utilizing the interference fit between the pins 15 and the holes, and the elastic deformation of the metal material, a firm connection is achieved between the two sets of fixing components, forming a complete and stable hot riveting positioning working surface. For different specifications of vacuum-formed isolation panels, the tooling can be adapted by replacing the type of spacer 13. The operator can quickly disassemble the original spacer and replace it with a suitable model according to the size and shape characteristics of the isolation panel. This modular design allows the tooling to cover a full range of products, from micro-precision isolation panels to large, complex structure isolation panels, without requiring modifications to the overall structure, significantly improving the equipment's versatility and production flexibility. Throughout the entire process, the precision guiding system of the high-precision slide rail 1 and the sliding block 2 ensures the precise docking of the dual-unit components, the high-strength connection of the docking locking part 5 ensures the stability during the hot riveting process, and the quick replacement mechanism of the form pad 13 gives the tooling a strong specification adaptability, ultimately achieving efficient, accurate and flexible hot riveting positioning operation.
