[0002] In modern industrial production, tooling fixtures are key equipment for ensuring product processing accuracy and improving production efficiency. Their performance directly affects a company's production efficiency and product quality. Traditional fixed tooling often suffers from poor versatility. When faced with processing requirements for different specifications or types of products, it is often necessary to change the entire set of tooling. This not only consumes a lot of time and costs but also severely restricts the flexibility and efficiency of production. In industries such as electronic equipment manufacturing and automotive parts processing, products are frequently updated, and product dimensions and structures are constantly changing. Traditional fixed tooling cannot quickly adapt to these changes, leading companies to invest too many resources in the production preparation stage, making it difficult to improve production efficiency.

[0003] To overcome the limitations of traditional tooling, the development of a highly adaptable fixed tooling capable of quickly replacing key components to suit different products is particularly urgent. Against this backdrop, a replaceable internal pressure fixed tooling has emerged. It aims to achieve efficient application of tooling in the processing of various products through innovative structural design, reducing enterprise production costs, improving production efficiency, and providing strong support for efficient and flexible production in modern manufacturing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a replaceable internal pressure fixed tooling, which solves the problem of poor versatility often found in traditional fixed tooling. When faced with processing requirements for products of different specifications or types, it is often necessary to replace the entire set of tooling, which not only consumes a lot of time and costs, but also seriously restricts the flexibility and efficiency of production. In industries such as electronic equipment manufacturing and automotive parts processing, products are frequently updated and their sizes and structures are constantly changing. Traditional fixed tooling cannot quickly adapt to these changes, leading to enterprises investing too many resources in the production preparation stage and making it difficult to improve production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a replaceable internal pressure type fixing fixture, including a base, with lateral slides fixedly connected to the front and rear sections of the top of the base, a cylinder fixedly installed in the middle section of the top of the base, a push rod fixedly connected to the output end of the cylinder, a pneumatic push plate fixedly connected to one inner end of the push rod, an inner pressure block fixing plate fixedly installed on the top inner side of the pneumatic push plate, a replaceable inner pressure block slidably connected to the inner wall of the inner side of the inner pressure block fixing plate, a guide post slidably connected to the inner wall of the limiting hole opened on the inner side of the replaceable inner pressure block, and a pressure plate fixing plate fixedly connected to the top left end of the base, the inner pressure block fixing... A sliding rod is slidably connected to the inner wall of the rear section of the pressure plate. A pressing block is fixedly connected to the rear end of the sliding rod. A return spring is sleeved on the outer wall of a section inside the sliding rod. A wedge block is fixedly connected to one end of the inner side of the sliding rod. A limiting guide is fixedly connected to the bottom of the inner wall of the middle section of the pressure plate. A fixed round block is slidably connected to the top outer wall of the limiting guide. A limiting round block is fixedly connected to the outer end of the fixed round block. A semi-circular block is fixedly connected to the outer end of the limiting round block. An arc-shaped slip ring is slidably connected to the outer wall of the limiting round block. A pneumatic push plate of the product body is snapped onto the top of the base and slidably connected to the inner wall of the side slide.

[0006] A further improvement is that the inner pressure block fixing plate is fixedly connected to the inner wall of the top of the pressure plate fixing plate, and the two inner pressure block fixing plates are symmetrically arranged; as the pneumatic push plate moves, the inner pressure block fixing plate installed on its inner top also moves forward synchronously; a replaceable inner pressure block is slidably connected to the inner side of the inner pressure block fixing plate, and the replaceable inner pressure block can be replaced according to the different specifications and shapes of the product body to achieve adaptation to different products.

[0007] A further improvement is that the replaceable inner pressure block is symmetrically arranged inside the inner pressure block fixing plate to limit the connection of the top product body; the product body is placed on top of the replaceable inner pressure block and snapped into place, and a guide post is slidably connected to the inner wall of the limiting hole opened inside the replaceable inner pressure block. The guide post plays a positioning and guiding role, ensuring the stability of the replaceable inner pressure block during movement and preventing it from shifting, thereby ensuring that the product body can be accurately fixed in the working position.

[0008] A further improvement is that the pressing block is slidably connected to the inner wall of the inner pressure block fixing plate; the sliding rod slidably connected to the inner wall of the rear section of the inner pressure block fixing plate has a pressing block fixedly connected to its rear end. When it is necessary to replace or adjust the replaceable inner pressure block, the operator presses the pressing block, and the pressing block drives the sliding rod to slide towards the inner side of the inner pressure block fixing plate; the wedge block fixedly connected to one end of the inner side of the sliding rod moves accordingly, the wedge block is slidably connected to the inner wall of the inner pressure block fixing plate, and its inner end abuts against the outer wall of the limiting circle block.

[0009] A further improvement is that the wedge block is slidably connected to the inner wall of the inner pressure block fixing plate, and one end of the wedge block abuts against the outer wall of the limiting circle block; a semi-circular block is fixedly connected to the outer end of the limiting circle block, and an arc-shaped slip ring is slidably connected to the outer wall; when the limiting circle block moves outward, it causes the semi-circular block to disengage from the limiting effect on the replaceable inner pressure block, at which point the replaceable inner pressure block can be easily disassembled and replaced; after replacement, the pressing block is released, the reset spring is sleeved on a section of the outer wall inside the slide rod, and the elastic force generated by it pushes the slide rod to reset outward, the wedge block moves outward accordingly, releasing the pushing effect on the limiting circle block, and the limiting circle block moves inward under the action of the reset force, and the semi-circular block re-limits and fixes the replaceable inner pressure block, ensuring the stability of the replaceable inner pressure block in subsequent work.

[0010] A further improvement is that the limiting guide is slidably connected to the inner wall of the limiting groove opened at the bottom of the fixed circular block; after the replacement is completed, the pressing block is released, the return spring is sleeved on a section of the outer wall inside the slide rod, and the elastic force generated by it pushes the slide rod to return to its original position. The wedge block moves outward accordingly, releasing the push on the limiting circular block. Under the action of the return force, the limiting circular block moves inward, and the semi-circular block re-limits and fixes the replaceable inner pressure block, ensuring the stability of the replaceable inner pressure block in subsequent work.

[0011] By employing the above technical solution, this utility model provides a replaceable internal pressure fixing fixture, which has at least the following beneficial effects:

[0012] 1. This utility model, by setting a replaceable internal pressure block, allows for quick replacement according to the specifications and shape of different product bodies, which greatly improves the applicability of the tooling. In traditional tooling, the entire tooling set often needs to be replaced to meet the processing requirements of different products, which is not only time-consuming and labor-intensive but also increases production costs. However, this tooling only requires replacing the key component, the replaceable internal pressure block, to fix multiple products, greatly shortening production preparation time and improving production efficiency. It also reduces the number of tooling inventories, lowers the company's equipment procurement and maintenance costs, and enables the company to respond more flexibly to changes in market demand, thereby improving the company's market competitiveness.

[0013] 2. In the process of fixing the product body, this utility model uses a cylinder as a power source, pushing a pneumatic push plate smoothly along the lateral slide via a push rod, ensuring the stability of the movement. The replaceable inner pressure block, positioned and guided by the guide post, accurately limits and fixes the product body, preventing it from shifting during processing. Furthermore, the limiting and unlocking mechanism, composed of components such as a pressing block, slide rod, wedge block, and limiting circular block, reliably fixes and replaces the replaceable inner pressure block, further ensuring the stability of the tooling under different working conditions. This stable and accurate fixing method helps improve the processing precision and quality of the product, reduces the scrap rate, and brings better economic benefits to the enterprise.

[0023] 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.

[0024] Traditional fixed tooling often suffers from poor versatility. When faced with processing requirements for different specifications or types of products, it is often necessary to replace the entire set of tooling. This not only consumes a lot of time and costs but also severely restricts the flexibility and efficiency of production. In industries such as electronic equipment manufacturing and automotive parts processing, products are frequently updated, and product sizes and structures are constantly changing. Traditional fixed tooling cannot quickly adapt to these changes, leading to excessive resource investment in the production preparation stage and difficulty in improving production efficiency. This embodiment provides a replaceable internal pressure fixed tooling. Please refer to... Figures 1-6 The embodiment provides a replaceable internal pressure type fixing fixture, including a base 1. Lateral slides 2 are fixedly connected to the front and rear sections of the top of the base 1. A cylinder 3 is fixedly installed in the middle section of the top of the base 1. A push rod 4 is fixedly connected to the output end of the cylinder 3. A pneumatic push plate 5 is fixedly connected to one inner end of the push rod 4. An internal pressure block fixing plate 6 is fixedly installed on the top inner side of the pneumatic push plate 5. A replaceable internal pressure block 7 is slidably connected to the inner wall of the internal pressure block fixing plate 6. A guide post 8 is slidably connected to the inner wall of the limiting hole opened on the inner side of the replaceable internal pressure block 7. A pressure plate fixing plate 9 is fixedly connected to the top of the left end of the base 1. A slide rod 10 is slidably connected to the inner wall of the rear section of the internal pressure block fixing plate 6. A pressing block 11 is fixedly connected to the rear end of the slide rod 10. A return spring 12 is sleeved on the outer wall of one inner section of the slide rod 10. A wedge block 13 is fixedly connected to one inner end of the slide rod 10. A limiting guide 14 is fixedly connected to the bottom of the inner wall of the middle section of the internal pressure block fixing plate 6. The top of the limiting guide 14... A fixed circular block 15 is slidably connected to the outer wall. A limiting circular block 16 is fixedly connected to the outer end of the fixed circular block 15. A semi-circular block 17 is fixedly connected to the outer end of the limiting circular block 16. An arc-shaped slip ring 18 is slidably connected to the outer wall of the limiting circular block 16. The product body 19 is snapped onto the top outer wall of the replaceable inner pressure block 7. A pneumatic push plate 5 is slidably connected to the top of the base 1, and the pneumatic push plate 5 is slidably connected to the inner wall of the side slide 2. The inner pressure block fixing plate 6 is fixedly connected to the top inner wall of the pressure plate fixing plate 9. The inner pressure plate 6 is symmetrically arranged with two inner pressure blocks; replaceable inner pressure blocks 7 are symmetrically arranged inside the inner pressure block fixing plate 6 to limit the connection of the top product body 19; pressing block 11 is slidably connected to the inner wall of the inner pressure block fixing plate 6; wedge block 13 is slidably connected to the inner wall of the inner pressure block fixing plate 6, and one end of the inner side of the wedge block 13 abuts against the outer wall of the limiting circle block 16; limiting guide 14 is slidably connected to the inner wall of the limiting groove opened at the bottom of the fixing circle block 15.

[0025] Working principle: When the product body 19 needs to be fixed for processing, the cylinder 3 is started first; the cylinder 3 serves as a power source, and its output end pushes the push rod 4 forward; the push rod 4 is fixedly connected to the pneumatic push plate 5, thus driving the pneumatic push plate 5 to slide forward along the top of the base 1 and the inner wall of the side slide 2; since the sliding of the pneumatic push plate 5 is guided by the side slide 2, its movement stability and accuracy can be ensured.

[0026] As the pneumatic push plate 5 moves, the inner pressure block fixing plate 6 installed on its inner top also moves forward synchronously; a replaceable inner pressure block 7 is slidably connected to the inner side of the inner pressure block fixing plate 6. The replaceable inner pressure block 7 can be replaced according to the different specifications and shapes of the product body 19 to achieve adaptation to different products; the product body 19 is placed on top of the replaceable inner pressure block 7 and snapped into place. A guide post 8 is slidably connected to the inner wall of the limiting hole opened on the inner side of the replaceable inner pressure block 7. The guide post 8 plays a positioning and guiding role, ensuring the stability of the replaceable inner pressure block 7 during movement and preventing it from shifting, thereby ensuring that the product body 19 can be accurately fixed in the working position;

[0027] A sliding rod 10 is slidably connected to the inner wall of the inner pressure block fixing plate 6. A pressing block 11 is fixedly connected to its rear end. When the replaceable inner pressure block 7 needs to be replaced or adjusted, the operator presses the pressing block 11. The pressing block 11 drives the sliding rod 10 to slide inward to the inner side of the inner pressure block fixing plate 6. The wedge block 13 fixedly connected to one end of the inner side of the sliding rod 10 moves accordingly. The wedge block 13 is slidably connected to the inner wall of the inner pressure block fixing plate 6, and its inner end abuts against the outer wall of the limiting round block 16. As the wedge block 13 moves inward, its inclined surface pushes the limiting round block 16 outward.

[0028] The limiting block 16 is connected to the limiting guide frame 14 via the fixing block 15. The limiting guide frame 14 is fixedly connected to the bottom of the inner wall of the middle section of the inner pressure block fixing plate 6. The top outer wall of the fixing block 15 is slidably connected to the limiting guide frame 14. A semi-circular block 17 is fixedly connected to the outer end of the limiting block 16, and an arc-shaped slip ring 18 is slidably connected to the outer wall. When the limiting block 16 moves outward, it causes the semi-circular block 17 to disengage from the limiting effect on the replaceable inner pressure block 7. At this time, the replaceable inner pressure block 7 can be easily disassembled and replaced. After replacement, the pressing block 11 is released and the block is reset. Spring 12 is sleeved on a section of the outer wall inside the slide rod 10. The elastic force generated by spring 12 pushes the slide rod 10 to reset outward. Wedge block 13 moves outward accordingly, releasing the push on limit block 16. Limit block 16 moves inward under the action of reset force. Semicircular block 17 re-limits and fixes the replaceable inner pressure block 7, ensuring the stability of the replaceable inner pressure block 7 in subsequent work. The entire tooling achieves stable fixation of the product body 19 and convenient replacement of the replaceable inner pressure block 7 through the coordinated cooperation between the components, meeting the processing needs of different products.
