Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine processing, and more specifically, to a fully enclosed lifting four-side positioning mechanism. Background Art

[0002] With the increasing demand for intelligence, digitalization and flexibility in the mobile communications and electronic technology industries, digital devices such as mobile phones, tablets, and monitors have gradually become popular in all aspects of our daily lives. The popularity of these devices in the market has led to an increasingly strong demand for the production of their panels, back covers and other components. As the main material for these components, the production and processing of glass is particularly important. In particular, under the premise of ensuring the accuracy, aesthetics and service life of the products, the precision processing and CNC machine tool processing capabilities of these glass components have become increasingly important.

[0003] In order to prevent the tool from overheating during glass processing, we usually apply coolant to ensure the normal operation of the tool. This processing method, coupled with the necessary positioning of the product before processing, can ensure the accuracy and stability of the processing, thereby improving production efficiency and product quality. However, most of the glass processing positioning methods on the market today use four-sided fixtures and L-shaped reference rulers for positioning. These traditional positioning methods, especially in the context of the rapid development of the current intelligent manufacturing industry, their limitations and inefficiencies are gradually becoming apparent.

[0004] First of all, the traditional four-sided fixture and L-shaped reference ruler positioning method has specific requirements for the size, shape and specifications of the tool. In the actual production process, if a smaller diameter tool is used, although it can avoid collision with the positioning angle of the four-sided fixture or L-shaped reference ruler, this will form a bottleneck in improving production efficiency. In addition, even if we consider using a larger diameter tool to increase the processing speed, in the actual processing process, the positioning angle of the tool and the fixture frequently contacts, and even creates the risk of collision. The problems caused by this collision not only slow down the production progress and cause a decrease in production efficiency, but also are accompanied by a significant increase in the risk factor in production operations, making the risk of accidents in the production process a problem that cannot be ignored. Such consequences may even threaten the personal safety of equipment or employees, thereby significantly increasing the cost of production.

[0005] In addition, the sealing and protection of the jigs currently on the market are not ideal. For example, byproducts such as cutting fluid, glass powder and metal chips generated during the processing may penetrate into the jig, which not only affects the positioning accuracy of the jig, but also further affects the service life of the jig itself. If these byproducts accumulate in the jig for a long time without being effectively treated and cleaned, the jig may be damaged or even unusable over time. Utility Model Content

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0027] Reference Figures 1 to 5 As shown, the utility model discloses a fully enclosed lifting four-side positioning mechanism, specifically, the mechanism includes a fixture housing 10, an L-shaped ruler 20, a ruler driving assembly 30, a ruler fixing block 40 and a ruler base 40;

[0028] The jig housing 10 is provided with a accommodating space, the two ruler drive assemblies 30 are relatively arranged inside the jig housing 10, the output end of the ruler drive assembly 30 passes through the side wall of the jig housing 10 and is fixedly connected to one end of the ruler fixing block 40, the output end of the ruler drive assembly 30 passes through the side wall of the jig housing 10 for sealing, and the output direction of the ruler drive assembly 30 is at an acute angle with the side wall of the jig housing 10, and the setting of this output direction is conducive to improving the working efficiency of the mechanism. When the ruler drive assembly 30 works at a more effective angle, it can more directly and effectively transmit force to the target part, thereby improving the positioning efficiency and accuracy of the workpiece 80 of the mechanism. The other end of the ruler fixing block 40 is fixedly connected to the ruler base 40, and a plurality of L-shaped rulers 20 are relatively arranged on the top of the jig housing 10, and the L-shaped ruler 20 is detachably connected to the ruler base 40, and the ruler drive assembly 30 pushes the ruler fixing block 40, and the ruler fixing block 40 drives the L-shaped ruler 20 to realize the positioning of the workpiece 80. This arrangement provides a flexible operating space, and the position of the ruler can be adjusted according to the size or shape of the workpiece 80 to achieve more accurate positioning. The angle between the slide rail 302 and the side of the fixture housing 10 is set at 45°, which allows the ruler drive assembly to more effectively drive the L-shaped ruler and accurately locate the length and width of the glass workpiece; the angle between the slide rail 302 and the top surface of the fixture housing 10 is set at 20°, which can cooperate with the ruler drive assembly to adjust the height of the L-shaped ruler, so as to avoid the grinding wheel, reduce the conflict and friction between components, and effectively avoid damage to the equipment.

[0029] Furthermore, the ruler drive assembly 30 includes a slide plate 301, a slider 302, a guide rod 303, a guide rod fixing block 304, a joint block 305, a joint shaft 306 and a cylinder 307; the slider 302 is fixedly connected to both ends of the slide plate 301, and both ends of the slide plate 301 are provided with slide rails 3021 adapted to the slider 302, so that the slide plate 301 is slidably connected with the slide rails 3021; ​​the angle of the slide rails 3021 can also be slightly adjusted to meet the requirements of precise positioning, thereby enhancing the versatility of the equipment. One end of the guide rod fixing block 304 is fixedly connected to the slider 302, and the other end is fixedly connected to the guide rod 303. The guide rod 303 passes through the jig housing 10 and is connected to the ruler fixing block 40. The cylinder 307 is fixedly installed inside the jig housing 10. The output end of the cylinder 307 is fixedly connected to the articulated shaft 306. One end of the articulated block 305 is fixedly connected to the movable plate, and the other end is hinged to the articulated shaft 306. The guide rod 303 and the slide rail 3021 are arranged in parallel. The guide rod fixing block 304 is wedge-shaped. One end of the inclined surface of the guide rod fixing block 304 is fixedly connected to the slide plate 301. Through the drive of the cylinder 307, the articulated shaft 306 drives the articulated block 305 to flip. The slide plate 301 moves along the slide rail 3021 and drives the L-shaped ruler 20 to rise and fall. When the cylinder 307 is opened, the guide rod 303 extends, the ruler base 40 opens, and the L-shaped ruler 20 opens and is lower than the workpiece 80; when the cylinder 307 is retracted, the guide rod 303 is retracted, the ruler base 40 retreats, and the L-shaped ruler 20 is clamped and positioned and is higher than the workpiece 80. In this way, through the drive of the cylinder 307, the articulated shaft 306 drives the articulated block 305 to make the slide plate 301 move up and down along the slide rail 3021, thereby achieving precise positioning. The working process of the entire equipment is highly automated, easy to operate, accurate and efficient in positioning, and well solves the problems of low efficiency, inaccurate positioning, and large equipment wear that occur during the use of traditional positioning equipment.

[0030] Furthermore, an oil seal 3031 is provided on the guide rod 303. This design can prevent moisture or cutting fluid from entering the interior of the fixture housing 10, and can effectively protect the internal mechanical components. The entry of moisture may cause the internal mechanical parts to rust or malfunction, affecting the operating accuracy and reliability of the equipment. The setting of the oil seal 3031 ensures the long-term stable operation of the equipment. The equipment does not need to frequently repair or replace damaged parts, and can maintain continuous operation for a longer time, thereby improving production efficiency. A guide seal block 3032 is provided at the connection between the guide rod 303 and the side of the fixture. The guide seal block 3032 is provided with a through hole. The guide rod 303 passes through the through hole of the guide seal block 3032 and is connected to the ruler fixing block 40. The through hole of the guide seal block 3032 is close to one side of the oil seal 3031, and the oil seal 3031 is just passed through, which can effectively prevent the oil seal 3031 from being impacted or squeezed, thereby avoiding damage and ensuring its protection performance. The other side of the through hole of the guide seal block 3032 just allows the guide rod 303 to pass through, preventing liquid or tiny particles from penetrating the through hole into the interior of the fixture, effectively avoiding equipment failures caused by contamination and reducing the accuracy of movement. The fixture housing 10 includes a fixture cover 101, a fixture bottom plate 102 and a fixture side plate 102; the fixture cover 101, the fixture bottom plate 102 and the fixture side plate 102 are fixedly connected by screws, and a sealing strip is provided at the connection. The use of screw fixed connection and sealing strips can ensure that the fixation between the various components is more secure and reduce loosening caused by vibration or long-term use. It also makes it easy to disassemble the corresponding parts when it is necessary to repair or clean the internal components. Such structural strength ensures the stability and long-term durability of the equipment during operation. When handling operations involving liquids or dusty environments, this sealing protects the internal mechanical components from dust, moisture and other possible contaminants.

[0031] Furthermore, the ruler base 40 is provided with a T-shaped slot 60, and the L-shaped ruler 20 is provided with a U-shaped slot 70. Through the cooperation of the T-shaped slot 60 and the U-shaped slot, the L-shaped ruler 20 can be moved left and right on the ruler base 40 by screwing a screw, so that the operator can easily and quickly adjust the position of the L-shaped ruler 20 without using complicated tools or procedures, thereby improving the convenience of operation of the device. The U-shaped slot 70 can adjust the position of the L-shaped ruler 20 within a certain range, so that the device can adapt to workpieces 80 of different sizes, thereby increasing the adaptability and flexibility of the device, so that the device can be applied to more types of workpieces 80.

[0032] The beneficial effects of the utility model are: it has good sealing performance, can effectively prevent pollution generated during the processing to increase the service life of the fixture, the size is easy to adjust, and can be applied to the simultaneous positioning and processing of a single product or multiple products, thereby improving positioning efficiency, increasing production efficiency, and ensuring product quality.

[0033] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
