Description

Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a magnetically positioned wrench processing fixture. Background Technology

[0002] Hand tools play an indispensable role in every corner of modern industry and daily life. From the construction of skyscrapers to the repair of precision instruments; from the disassembly and assembly of cars to the repair of simple household items, hand tools, with their unique flexibility and convenience, have become powerful assistants for people to complete various tasks.

[0003] Among the many family of hand tools, the wrench is undoubtedly one of the most commonly used and versatile, widely applied in fields such as machinery manufacturing, automobile repair, and home repair. Its working principle is based on the lever principle; by applying external force to the handle, it tightens or loosens threaded fasteners such as bolts and nuts by rotating them in the direction of the thread rotation.

[0004] There are many types of wrenches, the most common being open-end wrenches, box wrenches, combination wrenches, adjustable wrenches, hook wrenches, socket wrenches, Allen wrenches, and torque wrenches. Each type of wrench has its unique design and applicable scenarios. Open-end wrenches have a fixed-size opening at one or both ends, specifically designed for tightening nuts or bolts of a specific size; they are essential tools in the machinery industry for processing, production, and maintenance. Box wrenches have working ends with hexagonal or dodecagonal holes, making them particularly suitable for situations where working spaces are limited and ordinary wrenches are difficult to use. Combination wrenches cleverly combine the features of open-end wrenches and box wrenches; one end is the same as an open-end wrench, and the other end is the same as a box wrench, allowing both ends to tighten bolts or nuts of the same size, playing an important role in equipment installation and maintenance. Adjustable wrenches have an adjustable opening width within a certain range, allowing for flexible tightening of bolts or nuts of different sizes; however, their operation is relatively complex, requiring the rotation of a worm gear to adjust the opening size.

[0005] A fixed-opening wrench, with one or both ends having a fixed-size opening, is specifically designed for tightening nuts or bolts of a particular size and is an important tool in the machinery industry for machining, production, and maintenance. A box wrench has working ends with hexagonal or dodecagonal holes, making it particularly suitable for situations where working spaces are limited and ordinary wrenches are difficult to use. A combination wrench cleverly combines the features of a single-opening wrench and a box wrench; one end is the same as a single-opening wrench, and the other end is the same as a box wrench, allowing both ends to tighten or loosen bolts or nuts of the same size, playing an important role in equipment installation and maintenance. An adjustable wrench has an adjustable opening width within a certain range, allowing for flexible tightening or loosening of bolts or nuts of different sizes, but its operation is relatively complex, requiring the rotation of a worm gear to adjust the opening size.

[0006] Traditional ink filling methods primarily involve manual filling using syringes. Workers must hold the syringe and carefully inject ink into the markings on the wrench. While this method is simple and low-cost, it also has many limitations. The precision of manual operation is difficult to guarantee, easily leading to uneven ink filling and overflow, affecting the product's appearance and quality. Furthermore, manual filling is extremely inefficient; a skilled worker can only complete a limited number of wrenches per day, which cannot meet the demands of large-scale production. With rising labor costs, the cost disadvantages of manual filling are becoming increasingly apparent.

[0007] With continuous technological advancements, visual ink filling machines have emerged, providing a new solution for ink filling in wrenches. Utilizing advanced machine vision technology, these machines can quickly and accurately identify the position of the wrench's specification markings and evenly fill them with ink through a precise spraying system. This equipment not only significantly improves the accuracy and quality of filling but also dramatically increases production efficiency.

[0008] Because coloring machines vibrate during ink spraying, wrenches require specialized clamps for positioning. In today's consumer market, personalized needs are increasingly becoming mainstream. Consumers are no longer satisfied with standardized, mass-produced products; they want wrenches customized to their specific requirements. This trend has led to a surge in small-batch, personalized wrench production orders. More and more customers are requesting unique logos, special specifications, or personalized designs on their wrenches. For businesses, meeting these personalized needs not only enhances customer satisfaction but also opens up new market opportunities and increases product added value. However, the small-batch, personalized production model has brought new challenges to wrench manufacturing, with the frequent change of fixtures being particularly prominent. In traditional production methods, each wrench of different specifications or designs requires a dedicated positioning fixture. When companies need to frequently switch between producing different types of wrenches, they have to change fixtures frequently. Each fixture change means a production line stoppage, resulting in idle and wasted equipment and manpower. Moreover, frequent fixture changes can also lead to accelerated damage and wear of the fixtures, further increasing the company's operating costs. Therefore, how to design a fixture that can meet the processing needs of different types of wrenches is a technical problem that urgently needs to be solved in this case. Utility Model Content

[0009] To address the above problems, this utility model provides a magnetically positioned wrench processing fixture that is compact in structure, easy and efficient to use, low in manufacturing and maintenance costs, and can accommodate different types of wrenches.

[0010] The technical solution of this utility model is: A magnetically positioned wrench processing fixture, comprising: Non-metallic base plate with a hollow section in the middle; A magnetic metal pad is disposed within the hollow portion, and its thickness is less than that of the non-metallic base plate. A non-metallic strip is detachably mounted on the top of the metal pad, and the top has a groove adapted to multiple wrench placement areas; a magnetic strip is fixedly mounted in the groove; A strong magnet is fixedly installed at the bottom of the non-metallic strip, and the non-metallic strip is fixed to the magnetic metal pad by the magnetic force of the strong magnet.

[0011] Specifically, the non-metallic base plate is a polyurethane base plate.

[0012] Specifically, the non-metallic strip is a polyurethane strip.

[0013] Specifically, the bottom of the non-metallic strip is provided with a receiving groove adapted to the strong magnet.

[0014] Specifically, the receiving groove and the strong magnet are each provided in a pair.

[0015] Specifically, the strong magnet is cylindrical.

[0016] Specifically, the top surface of the magnetic metal pad is provided with a positioning groove that is compatible with the strong magnet.

[0017] Specifically, at least one pair of the non-metallic strips are provided, and their length is equal to the width of the magnetic metal pad.

[0018] Specifically, the non-metallic base plate has arc-shaped grooves at the corners of its hollowed-out portion.

[0019] Specifically, the top surface of the non-metallic strip is located above the top surface of the non-metallic base plate.

[0020] This invention involves machining a groove identical to a metal pad into a polyurethane base plate. The metal pad is then embedded into the polyurethane base plate to form a single unit. Magnetic strips and strong magnets are embedded into the top and bottom surfaces of non-metallic strips to form a single unit. The distance between the two non-metallic strips is adjusted according to the product shape, and one side of the strong magnet is used to attach them to the magnetic metal pad. A wrench to be colored is laid flat on the magnetic strip of the polyurethane non-metallic strip.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is for reference. Figure 1-5 Describe this utility model; A magnetically positioned wrench processing fixture, comprising: The non-metallic base plate 100 has a hollowed-out section 110 in the middle; the non-metallic base plate 100 in this case is a polyurethane base plate. Polyurethane has the characteristics of being resistant to high and low temperatures (-40℃~80℃) and chemical corrosion (such as ink solvents and cleaning agents), which can be adapted to scenarios such as "ink spraying" and "post-cleaning" in wrench processing, avoiding base plate deformation, aging and cracking due to corrosion, and its lifespan can be extended by 30%~50% compared with traditional plastic base plates (such as PP).

[0026] A magnetic metal pad 200 is disposed inside the hollow portion 110 and is in contact with the inner sidewall of the hollow portion 110. Its thickness is less than that of the non-metallic base plate 100. A non-metallic strip block 300 is detachably mounted on the top of the metal pad 200, and the top has a groove adapted to multiple wrench placement areas; a magnetic strip 400 is fixedly mounted in the groove; in this case, the non-metallic strip block 300 is a polyurethane strip block. The top surface of the non-metallic strip block 300 is located above the top surface of the non-metallic base plate 100.

[0027] A strong magnet 500 is fixedly installed at the bottom of the non-metallic strip 300, and the non-metallic strip 300 is fixed to the magnetic metal pad 200 by the magnetic force of the strong magnet 500.

[0028] This design utilizes the magnetic attraction between a strong magnet 500 and a magnetic metal pad 200 to quickly fix or disassemble a non-metallic strip 300 without the need for traditional clamping operations such as bolt tightening or snap-fitting. For small-batch production of customized wrenches, the magnetic strip in the groove can directly attract the wrench, preventing it from shifting during processing (such as ink coloring) and meeting the fixing needs of wrenches of different specifications.

[0029] At least one pair of non-metallic strips 300 are provided, the length of which is equal to the width of the magnetic metal pad 200. The length is... Figure 3 The distance marked "L" on the non-metallic strip 300 is equal to the distance marked "W" on the magnetic metal pad 200. The bottom of the non-metallic strip 300 has a receiving groove adapted to the strong magnet 500. The strong magnet 500 is cylindrical.

[0030] The receiving groove and the strong magnet 500 are each provided in pairs. The pair of strong magnets 500 (usually symmetrically distributed at both ends of the long strip) can form a "two-point fixation", which uses the principle of "two points determine a straight line" to prevent the non-metallic long strip 300 from rotating or shifting on the magnetic metal pad.

[0031] The top surface of the magnetic metal pad 200 is provided with a positioning groove that is compatible with the strong magnet 500, so that the non-metallic strip 300 can be placed on the magnetic metal pad 200 quickly and accurately.

[0032] The non-metallic base plate 100 has an arc-shaped groove 111 at the corner of the hollow part 110.

[0033] If the corners of the perforated part of the polyurethane base plate are right angles, they are prone to cracking due to stress concentration after long-term use; the arc design can disperse stress, avoid structural damage to the base plate caused by vibration and disassembly stress, and extend the service life of the base plate; at the same time, it facilitates the later maintenance and replacement of the magnetic metal pad 200.

[0034] This invention involves machining a groove identical to a metal pad into a polyurethane base plate. The metal pad is then embedded into the polyurethane base plate to form a single unit. Magnetic strips and strong magnets are embedded into the top and bottom surfaces of non-metallic strips to form a single unit. The distance between the two non-metallic strips is adjusted according to the product shape, and one side of the strong magnet is used to attach them to the magnetic metal pad. A wrench to be colored is laid flat on the magnetic strip of the polyurethane non-metallic strip. The coloring machine uses visual recognition to locate the area to be colored, moves the inkjet head to fill it with ink, and the wrench is attracted to the magnetic strip due to its magnetism. The vibration force generated by the printhead during movement is less than the magnetic attraction force, allowing for precise ink spraying. To change products, simply adjust the distance between the non-metallic strips for quick fixture replacement.
