Description

Technical Field

[0001] This invention relates to a multifunctional irregular-shaped bench vise, which is particularly suitable for the processing and clamping of irregular-shaped workpieces, and belongs to the field of machining technology. Background Technology

[0002] Traditional bench vises typically feature a planar clamping structure, suitable for workpieces with regular shapes. However, in actual inspection processes, irregularly shaped workpieces are frequently encountered, and traditional bench vises struggle to clamp them effectively, leading to measurement errors or even preventing the completion of the inspection task. Furthermore, traditional bench vises have limited functionality and cannot meet diverse inspection needs. For example, when inspecting complex curved surfaces, irregular geometries, or precision parts, traditional bench vises often fail to provide sufficient clamping stability, causing workpiece displacement or deformation during inspection, thus affecting the accuracy of the results. Simultaneously, traditional bench vises lack flexible angle adjustment and quick-change functions, making them ill-suited for diverse inspection scenarios. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and solve the limitations of traditional bench vises when clamping irregularly shaped workpieces.

[0004] The objective of this invention is achieved through the following technical solutions:

[0005] A multifunctional irregular-shaped bench vise includes a fixed-end body and a moving-end body. The base body adopts a cuboid structure, and its bottom and sides are precision machined to have a high degree of flatness. It can be quickly fixed to the workbench using a universal clamp to ensure overall stability.

[0006] The fixed end body and the moving end body are respectively set on both sides of the base body. The moving end body is connected to the base body through an adjustment mechanism and can move flexibly along the length of the base to adapt to workpieces of different sizes.

[0007] The fixed and moving ends of the vise are equipped with circular adapters of different sizes. The design of these adapters gives the vise a high degree of two-dimensional freedom, enabling multi-angle adjustment. By cooperating with the irregularly shaped clamping surface of the four-stage base, the vise can effectively clamp workpieces of various shapes, meeting the clamping requirements of complex workpieces.

[0008] This structural design not only improves the flexibility and adaptability of clamping, but also ensures the stability and accuracy of the workpiece during the machining process.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] (1) The base body of the present invention is made of high-strength alloy material, which has excellent pressure resistance and wear resistance, and can adapt to high-intensity processing environment. The clamping surface (the clamping surface is composed of four circular adapter seats of the fixed end body and four circular adapter seats of the moving end body) is covered with anti-slip and wear-resistant coating, which further enhances durability.

[0011] (2) The moving end body and the fixed end body of the present invention adopt a multi-level circular adapter design, which has a high degree of two-dimensional freedom and can realize multi-angle adjustment to meet the mounting requirements of complex workpieces.

[0012] (3) The adapters of the present invention are tightly connected by sliding dovetail grooves, which effectively reduces the entry of foreign objects into the gaps and avoids damage to the rotating mechanism due to the intrusion of foreign objects.

[0013] (4) The bottom and sides of the main body base of the present invention are precision machined and have high flatness. They can be quickly fixed on the workbench by a universal clamp to ensure overall stability.

[0014] (5) This invention is applicable to many fields such as precision machining, mold manufacturing, assembly and maintenance, high-precision testing and education and training, and has a wide market application prospect.

[0015] (6) The present invention can effectively clamp workpieces of various shapes and can automatically adjust the clamping force and contact area according to the shape, size and material of the workpiece, so as to ensure that the workpiece is subjected to uniform force during processing, inspection or assembly, and avoid deformation or damage caused by excessive local stress.

[0016] (7) The present invention adopts a modular design, which can be quickly disassembled and replaced, greatly simplifying the maintenance and repair process and reducing the cost of use and time.

[0017] (8) This invention can not only improve detection efficiency and accuracy, but also expand the detection range to meet the needs of modern industry for high-precision and high-efficiency detection tools; through modular design, this invention can provide a more flexible and reliable solution for detection work.

[0018] (9) The present invention uses an irregular clamping surface and a multi-stage circular adapter, which can automatically adjust the clamping angle according to the shape of the workpiece so that the workpiece is subjected to uniform force, thereby ensuring that the workpiece remains stable during processing and inspection.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0027] A multifunctional irregular-shaped bench vise includes: a fixed-end primary circular adapter 1, a moving-end primary circular adapter 2, a fixed-end primary adapter limit screw 3, a moving-end primary adapter limit screw 4, a fixed-end secondary circular adapter 5, a moving-end secondary circular adapter 6, a fixed-end secondary adapter limit screw 7, a moving-end secondary adapter limit screw 8, a fixed-end tertiary circular adapter 9, a moving-end tertiary circular adapter 10, a fixed-end tertiary adapter limit screw 11, and a moving-end tertiary adapter limit screw 12. The system comprises: a fixed-end four-stage base 13, a moving-end four-stage base 14, a fixed-end four-stage base limiting screw 15, a moving-end four-stage base limiting screw 16, a fixed-end adapter limiting groove 17, a moving-end adapter limiting groove 18, a limiting groove mounting screw 19, a screw 20, a screw locating pin 21, a moving-end threaded sleeve 22, a moving-end limiting screw 23, a main body slide 24, a main body threaded mounting sleeve 25, a main body mounting sleeve limiting screw 26, a base body 27, a slide mounting screw 28, and a moving-end base 29. The specific structure is as follows... Figure 1 , Figure 2 As shown.

[0028] The fixed-end primary circular adapter 1, fixed-end primary circular adapter limit screw 3, fixed-end secondary circular adapter 5, fixed-end secondary adapter limit screw 7, fixed-end tertiary circular adapter 9, fixed-end tertiary adapter limit screw 11, fixed-end quaternary base 13, fixed-end quaternary base limit screw 15, fixed-end adapter limit groove 17, main body threaded mounting sleeve 25, main body mounting sleeve limit screw 26, and base body 27 constitute the fixed-end body. The fixed-end adapter limit groove 17 is installed into the base body 27 and fixed using the limit groove mounting screw 19. To prevent the fixed-end primary circular adapter 1 from sliding out during rotation, the fixed-end primary circular adapter limit screw 3 is installed into the fixed-end primary circular adapter 1. After the fixed-end secondary circular adapter 5 slides into the fixed-end primary circular adapter 1 through the dovetail groove, the fixed-end secondary adapter limit screw 7 is used to prevent it from sliding out. After the fixed-end three-stage circular adapter 9 and the fixed-end two-stage circular adapter 5 are slid into each other through the dovetail groove, the fixed-end three-stage adapter limiting screw 11 is used to prevent them from sliding out. After the fixed-end four-stage base 13 and the fixed-end three-stage circular adapter 9 are slid into each other through the dovetail groove, the fixed-end four-stage base limiting screw 15 is used to prevent them from sliding out. The exploded view of its internal structure is shown below. Figure 3 As shown in the diagram. The circular adapters are tightly connected via precisely designed sliding dovetail grooves. The radius of each stage of the circular adapter gradually decreases, with the fixed-end stage 1 having the largest radius. (See schematic diagram). Figure 4 As shown. The main body threaded mounting sleeve 25 needs to be assembled onto the base body 27, located at the end closest to the moving end body. It is precisely positioned by the main body mounting sleeve limiting screw 26 to ensure accurate installation and effectively prevent relative displacement between components.

[0029] To ensure the connection stability and smooth sliding of the dovetail groove structure, and to reduce the entry of foreign objects into the gaps of the adapter seats, thus preventing damage to the rotating mechanism due to foreign object intrusion, the mating clearance of each level of the circular adapter seats of the fixed end body and the moving end body is set to 0.010-0.015mm. The surface finish of the dovetail groove is controlled below Ra1.6, and the cylindricity of each level of the circular adapter seats is less than 0.010mm and the coaxiality is less than 0.020mm, thereby effectively avoiding problems such as jamming during the sliding process of the adapter seats.

[0030] To protect the base body 27 and reduce the impact of wear caused by long-term use of the adapter, a moving-end adapter limiting groove 18 and a fixed-end adapter limiting groove 17 are specially designed to connect the base body 27 and the moving-end base 29, respectively. Simultaneously, by installing the fixed-end first-stage adapter limiting screw 3 and the moving-end first-stage adapter limiting screw 4 (the limiting screws have no threads at the front end to prevent the screws from becoming irremovable due to wear between the limiting grooves and the adapter limiting screws), the fixed-end first-stage circular adapter 1 and the moving-end first-stage circular adapter 2 are further prevented from sliding out of the base body 27, as shown in the schematic diagram. Figure 5As shown. This design not only improves the reliability of the structure but also significantly enhances the overall durability, ensuring that the vise maintains high performance and stability during long-term use.

[0031] The moving end main body is composed of the following components: moving end primary circular adapter 2, moving end primary adapter limit screw 4, moving end secondary circular adapter 6, moving end secondary adapter limit screw 8, moving end tertiary circular adapter 10, moving end tertiary adapter limit screw 12, moving end quaternary base 14, moving end quaternary base limit screw 16, moving end adapter limit groove 18, limit groove mounting screw 19, screw 20, screw locating pin 21, moving end threaded sleeve 22, moving end limit screw 23, main body slide 24, slide mounting screw 28, and moving end base 29.

[0032] The screw 20 is installed into the moving end sleeve 22 and fixed by the screw positioning pin 21 to prevent relative displacement between components. The moving end sleeve 22 is installed into the moving end base 29 and fixed by the moving end limiting screw 23 to ensure reliable component positioning. The moving end adapter seat limiting groove 18 is installed at the front of the moving end base 29 and fixed by the limiting groove mounting screw 19. To prevent the moving end first-stage circular adapter seat 2 from sliding out during rotation, the moving end first-stage adapter seat limiting screw 4 is installed in the moving end first-stage adapter seat 2. The moving end second-stage circular adapter seat 6 slides into the moving end first-stage circular adapter seat 2 through the dovetail groove and is prevented from sliding out by the moving end second-stage adapter seat limiting screw 8. The moving end third-stage circular adapter seat 10 slides into the moving end second-stage circular adapter seat 6 through the dovetail groove and is prevented from sliding out by the moving end third-stage adapter seat limiting screw 12. The radius of each stage of the circular adapter seat gradually decreases, with the moving end first-stage circular adapter seat 2 having the largest radius. After the moving end four-stage base 14 and the moving end three-stage circular adapter 10 slide into each other through the dovetail groove, the moving end four-stage base limiting screw 16 is used to prevent them from sliding out. The main body slide 24 is installed onto the moving end base 29 and fastened by the slide mounting screw 28. The screw 20 is screwed into the main body threaded mounting sleeve 25, realizing the combination of the moving end main body and the fixed end main body; its exploded view is as follows. Figure 6 , Figure 7 As shown.

[0033] The base body 27 adopts a cuboid structure, with its bottom and sides machined with high precision to ensure that the flatness of the sides is less than 0.010 mm, the parallelism between the sides is less than 0.020 mm, and the perpendicularity between the sides and the base is less than 0.020 mm. This high-precision machining design not only provides convenient workpiece alignment conditions when using tooling later, but also significantly improves the overall stability and operating accuracy of the vise. In addition, the base body can be quickly fixed to the worktable using a universal fixture, further enhancing its stability and reliability during the machining process, ensuring the efficiency and accuracy of workpiece clamping and machining.

[0034] This invention provides a multifunctional irregular-shaped vise. Through innovative structural design and multifunctional integration, it solves the problems of uneven force distribution, limited functionality, and inconvenient maintenance associated with traditional vises when clamping irregularly shaped workpieces. The vise employs an adaptive clamping structure that effectively clamps workpieces of various shapes, ensuring uniform force distribution and preventing workpiece deformation or damage. Simultaneously, its multi-stage circular adapter, interchangeable clamping modules, and angle adjustment function significantly improve operational flexibility and applicability. Furthermore, the modular design and foreign object intrusion prevention structure further enhance the vise's durability and ease of maintenance.

[0035] This invention is applicable to multiple fields such as precision machining, mold manufacturing, assembly and maintenance, and high-precision testing. It has broad market application prospects and significant technical advantages, providing a high-efficiency, reliable and easy-to-maintain clamping solution for modern manufacturing.
