Description

Technical Field

[0001] This utility model relates to the field of workpiece clamps, and in particular to a self-centering multi-position vise. Background Technology

[0002] In the machining industry, workpiece fixtures are indispensable tools. Their main function is to stably fix the workpiece on the worktable of the machining equipment to ensure that the workpiece does not shake or shift during the machining process, thereby ensuring machining accuracy and product quality. The design and use of workpiece fixtures are directly related to machining efficiency, production costs, and worker safety.

[0003] With the rapid development of the manufacturing industry, the shapes and sizes of workpieces are becoming increasingly diverse, and the requirements for workpiece fixtures are also becoming higher and higher. In particular, for slender workpieces, due to their large length-to-diameter ratio, they are prone to bending deformation during clamping, which affects the machining accuracy. Therefore, it is particularly important to design a fixture that can adapt to slender workpieces of different diameters, lengths and shapes, and that is stable in clamping and easy to adjust.

[0004] Traditional workpiece fixtures have some obvious technical problems when clamping slender workpieces; for example, uneven clamping force may cause the workpiece to bend or deform; the number of clamping units is limited and cannot adapt to workpieces of different lengths; the clamping surface lacks anti-slip design, and the workpiece is easy to slide during processing; these problems not only affect processing efficiency and product quality, but also increase the difficulty of operation for workers and safety hazards. Utility Model Content

[0005] To address the problems of limited adaptability and inconvenient adjustment of existing workpiece clamps for slender workpieces, this utility model provides a self-centering multi-position vise.

[0006] The self-centering multi-clamping vise provided by this utility model adopts the following technical solution:

[0007] A self-centering multi-position vise includes: a base having one or more clamping areas for mounting elongated workpieces; and a vise assembly detachably mounted on the base for clamping the workpieces. The vise assembly includes at least two clamping units arranged along the length of the workpiece, each clamping unit having a self-centering function, capable of automatically adjusting and clamping elongated workpieces of different diameters. The base has locating pin holes, and the bottom of the vise assembly has locating pin seats that match the locating pin holes, enabling rapid positioning and disassembly of the vise assembly from the base via the locating pins.

[0008] Furthermore, each of the clamping units includes: a base for connecting to a base via a positioning pin; a fixed jaw fixed to the top of the base; a movable jaw movably disposed opposite the fixed jaw for cooperating with the fixed jaw to clamp the workpiece; and an adjustment mechanism for adjusting the position of the movable jaw to achieve a self-centering function.

[0009] Furthermore, the adjustment mechanism includes: an adjustment bolt; a groove is provided at the bottom of the base; a slider is welded to the bottom of the movable jaw and slidably connected in the groove; the adjustment bolt is threaded to the outer wall of the base, and one end extends into the groove to abut against the slider; a return spring is provided between the inner wall of the groove and the slider to provide a return force after the movable jaw is adjusted.

[0010] Furthermore, the base is provided with multiple positioning pin holes, and the bottom of the vise assembly is provided with positioning pin seats that match the number of positioning pin holes, so that the vise assembly and the base can be stably connected through multiple positioning pins.

[0011] Furthermore, both the fixed jaws and the movable jaws have staggered anti-slip teeth on their clamping surfaces;

[0012] Furthermore, a quick-change base is installed at the bottom of the base; the quick-change base includes a fixed body and a suction cup set on the top of the fixed body, and the base is fixed by positioning through the suction cup;

[0013] Furthermore, both the vise assembly and the base are made of alloy steel, and their surfaces are hardened and chrome-plated to improve their hardness, wear resistance, and corrosion resistance.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] This invention designs multiple clamping units arranged along the length of the workpiece, each with a self-centering function, capable of adjusting and clamping slender workpieces of different diameters. This solves the problems of uneven clamping force and easy workpiece deformation in traditional fixtures, improving processing accuracy and product quality. The number and position of the clamping units can be adjusted according to the workpiece length to accommodate workpieces of different lengths. This avoids the problem that traditional fixtures cannot adapt to workpieces of different lengths due to the limited number of clamping units, improving the versatility and flexibility of the fixture.

[0016] The clamping surfaces of both the fixed and movable jaws feature staggered anti-slip teeth, increasing friction between the jaws and the workpiece surface and effectively preventing workpiece slippage during machining. This solves the problem of traditional fixtures lacking anti-slip design and allowing workpieces to easily slip, thus improving machining stability and safety. The base has multiple locating pin holes, and the bottom of the vise assembly has locating pin seats that match these holes, achieving a stable connection between the vise assembly and the base. This solves the problem of unstable and wobbly connections between traditional fixtures and bases, improving the stability of the fixture during operation. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail below:

[0024] This utility model discloses a self-centering multi-clamping vise, such as... Figure 1 , 2As shown, a self-centering multi-position vise includes: a base 2 having one or more clamping areas for mounting elongated workpieces; and a vise assembly detachably mounted on the base 2 for clamping the workpieces. The vise assembly includes at least two clamping units arranged along the length of the workpiece, each clamping unit having a self-centering function, capable of automatically adjusting and clamping elongated workpieces of different diameters. The base 2 has locating pin holes, and the bottom of the vise assembly has locating pin seats that match the locating pin holes. The locating pins 4 enable quick positioning and disassembly of the vise assembly from the base 2. In this embodiment, the base 2 serves as the basic component, providing clamping areas for placing elongated workpieces; the vise assembly is responsible for clamping the workpieces. The base 2 and the vise assembly are detachably connected, a design that facilitates replacement or adjustment of the vise assembly according to different work requirements. The multiple clamping units in the vise assembly are arranged along the length of the workpiece, and each clamping unit has a self-centering function, meaning they can automatically adapt to elongated workpieces of different diameters, achieving stable clamping of the workpieces through automatic adjustment.

[0025] like Figure 3 , 5 As shown, each clamping unit includes: a base 3 for connecting to the base 2 via a positioning pin 4; a fixed jaw 31 fixed to the top of the base 3; a movable jaw 32 movably disposed opposite the fixed jaw 31 for cooperating with the fixed jaw 31 to clamp the workpiece; and an adjustment mechanism for adjusting the position of the movable jaw 32 to achieve a self-centering function. In this embodiment, the base 3 is connected to the base 2 via the positioning pin 4, ensuring the stability of the clamping unit and preventing shaking or displacement when clamping the workpiece. The cooperation between the fixed jaw 31 and the movable jaw 32 provides a reliable clamping force, which can firmly clamp the workpiece. The adjustment mechanism allows for the adjustment of the movable jaw 32, enabling the clamping unit to adapt to workpieces of different diameters and improving the versatility of the vise.

[0026] like Figure 4As shown, the adjustment mechanism includes: an adjusting bolt 323; a groove 321 is provided at the bottom of the base 3; a slider 322 is slidably connected to the bottom of the movable jaw 32 within the groove 321; the adjusting bolt 323 is threaded to the outer wall of the base 3, with one end extending into the groove 321 to abut against the slider 322; and a return spring 324 is disposed between the inner wall of the groove 321 and the slider 322, used to provide a return force after the movable jaw 32 is adjusted. In this embodiment, when the position of the movable jaw 32 needs to be adjusted, the adjusting bolt 323 is rotated, causing the adjusting bolt 323 to move into the groove 321, pushing the slider 322 to slide within the groove 321, and the movable jaw 32 moves accordingly. When the workpiece diameter changes, the adjusting bolt 323 can be adjusted again to adapt the movable jaw 32 to the new diameter. When the adjusting bolt 323 is loosened and the workpiece is removed, the spring force of the return spring 324 will cause the slider 322 and the movable jaw 32 to return to their initial positions.

[0027] like Figure 1 , 2 As shown, the base 2 has multiple positioning pin holes, and the bottom of the vise assembly has positioning pin seats matching the number of positioning pin holes. Multiple positioning pins 4 achieve a stable connection between the vise assembly and the base 2. In this embodiment, when installing the vise assembly, the multiple positioning pin seats on the bottom of the vise assembly are aligned with the multiple positioning pin holes on the base 2, and then the positioning pins 4 are inserted to connect the vise assembly to the base 2. For disassembly, all positioning pins 4 are simply pulled out.

[0028] like Figure 5 As shown, both the fixed jaw 31 and the movable jaw 32 have staggered anti-slip teeth 5 on their clamping surfaces. In this embodiment, when the fixed jaw 31 and the movable jaw 32 clamp the workpiece, the anti-slip teeth 5 will contact the workpiece surface, increasing the contact area and friction, thereby firmly fixing the workpiece in the jaws. The anti-slip teeth 5 improve the clamping force of the jaws on the workpiece, effectively preventing the workpiece from sliding during processing, and ensuring the processing accuracy and quality of the workpiece.

[0029] like Figure 1 , 2 As shown, a quick-change base is installed at the bottom of the base 2. The quick-change base includes a fixed body 1 and a suction cup 11 set on the top of the fixed body 1. The base 2 is fixed by positioning through the suction cup 11. In this embodiment, when installing the base 2, the suction cup 11 of the quick-change base is brought into contact with the surface of the workbench, and the base 2 is fixed to the workbench by the suction of the suction cup 11. When it is necessary to replace or move the base 2, the suction force of the suction cup 11 is released, and the base 2 can be removed from the workbench. The design of the quick-change base realizes the quick installation and removal of the base 2, saves installation time, and improves work efficiency. The suction fixation method of the suction cup 11 provides a stable fixation effect and ensures the stability of the base 2 during operation.

[0030] Both the vise assembly and the base 2 are made of alloy steel, and their surfaces are hardened and chrome-plated to improve their hardness, wear resistance, and corrosion resistance. In this embodiment, the use of alloy steel ensures the strength and toughness of the vise assembly and the base 2, enabling them to withstand greater clamping and impact forces, thus extending the service life of the equipment. The hardening treatment improves the hardness and wear resistance of the material, reduces wear on the jaws and the surface of the base 2, and ensures the accuracy and stability of the equipment. The chrome plating treatment improves the corrosion resistance of the material, preventing the vise assembly and the base 2 from rusting in humid or corrosive environments, thereby extending the service life of the equipment.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
