Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to a special tool replacement fixture for machining. Background Technology
[0002] In the field of machining technology, the processing of specialized tools typically relies on traditional tooling. Tooling fixtures are process devices used to quickly clamp workpieces during machining, ensuring the correct relative positions of the machine tool, cutting tool, and workpiece. In other words, tooling fixtures are indispensable components of machining. However, most existing tooling uses vises to clamp blanks. This method requires reserving special clamping positions on the blank, which forces an increase in the size and weight of the blank. This not only directly increases the cost of raw materials but also indirectly increases the number of machining steps because the excess clamping portion requires additional processing. Utility Model Content
[0003] In view of this, this application proposes a special tooling replacement fixture that fixes parts with bolts, thereby reducing material costs and solving the problems mentioned in the background art.
[0004] This utility model provides the following technical solution: a special tool processing and replacement fixture, characterized in that it includes: a replacement plate, a base plate, a positioning pin, and a guide post;

[0028] Specific references Figure 1As a special tooling replacement fixture of this utility model, the device includes: a replacement plate 110, a base plate 100, a positioning pin 111, and a guide post 113; the replacement plate 110 is a planar plate structure with multiple positioning holes and multiple threaded holes 112 on the top, the positioning pin 111 is fixedly inserted into the positioning hole, which is suitable for positioning the part to be processed, and the part 120 can be fastened to the replacement plate 110 by bolts; the base plate 100 is a plate structure with guide posts 113 fixedly arranged around its perimeter, and the replacement plate 110 is fixed to the base plate 100 by the guide posts 113.
[0029] In this example, part 120 has multiple pin holes, and the positions of the pin holes match the positioning pins 111 on the replacement plate 110. The part 120 to be processed is initially positioned by the cooperation of the pin holes and the positioning pins 111, ensuring that the part will not undergo lateral displacement during processing, thus providing a basic guarantee for processing accuracy.
[0030] In this example, bolt 112 is located on the opposite side of replacement plate 110 relative to part 120. This fixing method ensures that the bolt does not interfere with the machining area of the part, avoids collision between the bolt and the tool during machining, and the method of fastening from the other side of the replacement plate allows the part to fit more tightly with the replacement plate, improving the fixing stability.
[0031] In this example, the replacement plate 110 has two handles 114 along its width, and the handles 114 are fixedly connected to the replacement plate 110. The handles facilitate the handling and installation of the replacement plate by the operator, especially when switching replacement plates, allowing for quick operation, saving time, and improving work efficiency. At the same time, the inner side of the handles has anti-slip textures, which increase the friction between the hand and the handle, preventing slippage during handling and further enhancing the safety and convenience of operation.
[0032] In this example, there are two replacement plates 110, and both replacement plates have the same shape. One replacement plate is fixed to the base plate 100 for part processing, while the other replacement plate can be used simultaneously for assembling and disassembling parts to be processed on the worktable. This design enables parallel operation of processing and clamping. While parts are being processed on one replacement plate, the next batch of parts can be clamped on the other replacement plate, effectively reducing clamping waiting time and significantly improving overall processing efficiency.
[0033] In this example, the replacement plate 110 has guide sleeves at both ends, and the positions of the guide sleeves match the guide posts 113 around the base plate 100. The replacement plate 110 and the base plate 100 are detachably connected. The cooperation between the guide sleeves and the guide posts ensures the positional accuracy of the replacement plate when it is installed on the base plate, avoiding the impact of installation deviation on the machining accuracy of the parts. The detachable connection facilitates switching between the two replacement plates.
[0034] In this example, the positioning holes are arranged side by side along the length of the replacement plate 110, with multiple positioning holes in each row. The positioning holes and threaded holes are located on the same vertical and horizontal line. This layout design facilitates batch clamping of multiple parts, making the parts more neatly arranged on the replacement plate. This not only improves clamping efficiency but also ensures consistency during the processing of multiple parts, enhancing processing stability.
[0035] In this example, the replacement plate 110 has rounded edges. The rounded edges avoid sharp corners, preventing operators from being scratched when handling or installing the replacement plate, thus improving safety during operation.
[0036] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
