Description

Technical Field

[0001] This utility model relates to the field of machine tool processing fixture technology, and in particular to a chuck anti-vibration and reinforcement fixture. Background Technology

[0002] Machine tools (such as lathes and milling machines) primarily use cutting tools to perform turning operations on rotating workpieces. Lathes can also be used to perform corresponding machining operations using drills, reamers, taps, dies, and knurling tools. Chucks are commonly used on machine tools, such as lathes or milling machines, to clamp workpieces, facilitating machining by the machine tool.

[0003] Chuck clamps are prone to vibration during high-speed rotation or machining of complex workpieces, which may lead to decreased machining accuracy, tool wear, or workpiece damage. This is particularly true when clamping and machining pipes; excessive clamping can cause pipe deformation, while insufficient clamping can cause vibration during machining. Furthermore, the hollow nature of pipes means that existing external clamping methods can easily cause elastic deformation during machining, further increasing the likelihood of vibration and resulting in decreased machining accuracy. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a chuck fixture for stable clamping of tubular workpieces and reducing vibration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chuck-type shockproof and reinforcing clamp for fixing pipe fittings includes:

[0007] The chuck body has multiple grooves arranged radially outward from the center on one side.

[0008] A double-threaded rod is coaxially disposed inside the chuck body;

[0009] The first threaded sleeve and the second threaded sleeve are respectively disposed at the two ends of the double-ended threaded rod. The double-ended threaded rod rotates to make the first threaded sleeve and the second threaded sleeve move away from each other.

[0010] And multiple clamping assemblies, each clamping assembly is slidably connected inside a groove, each clamping assembly includes a first clamping block, a second clamping block, a first connecting rod and a second connecting rod, the first connecting rod is disposed between the first threaded sleeve and the first clamping block, and the second connecting rod is disposed between the second threaded sleeve and the second clamping block, so that when the first threaded sleeve and the second threaded sleeve move away from each other, the first clamping block and the second clamping block move closer to each other.

[0011] Furthermore, a first rubber strip is provided on the side of the first clamping block and the second clamping block that are close to each other. A cavity is provided inside the chuck body. Each sliding groove is provided on one side wall of the chuck body. Limiting grooves are provided on both sides of the first clamping block and the second clamping block. The side wall of the chuck body can be inserted into the limiting groove. A second rubber strip is provided on the inner walls of both sides of the limiting groove.

[0012] Furthermore, a fixing rod is coaxially fixedly connected inside the chuck body, and a through hole is provided in the middle of the double-threaded rod. The double-threaded rod is slidably connected to the outside of the fixing rod.

[0013] Furthermore, a gear post is fixedly connected to one end of the double-threaded rod, and a rack is slidably connected inside the chuck body, with the rack meshing with the gear post.

[0014] Furthermore, a screw is rotatably connected to the top of the chuck body, a threaded hole is opened at the upper end of the rack, and the lower end of the screw is threadedly connected to the rack through the threaded hole. Fixed cylinders are fixedly connected to the top and bottom of the chuck body. The upper and lower ends of the rack are slidably connected to the inside of the two fixed cylinders respectively, and a hexagonal groove is provided at the upper end of the screw.

[0015] Furthermore, both ends of the double-ended threaded rod are provided with threaded grooves, and the thread directions of the threaded grooves at the two ends are opposite.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the chuck anti-vibration and reinforcement clamp rotates via a double-ended threaded rod, causing the first and second clamping blocks inside the slide groove to move closer together, thereby clamping the pipe wall. The first and second clamping blocks clamp the outer and inner walls of the pipe in both directions, effectively preventing deformation of the pipe while firmly clamping and fixing it, improving the stability of the clamping and preventing vibration caused by elastic deformation of the pipe wall during processing. Furthermore, since the double-ended threaded rod can move freely outside the fixed rod, the device can adapt to pipes of different diameters, facilitating the fixing of pipes of varying diameters.

[0028] Reference Figure 1-5 A chuck anti-vibration reinforcement fixture is used in pipe processing to improve the stability of clamping tubular workpieces and prevent them from vibrating.

[0029] The chuck anti-vibration and reinforcement fixture includes a chuck body 1, a double-ended threaded rod 10, a first threaded sleeve 6, a second threaded sleeve 7, and multiple fixture components;

[0030] The chuck body 1 has an internal cavity, and multiple sliding grooves 101 are radially arranged along the center of one side wall. Each clamping assembly is slidably connected to the inside of a sliding groove 101. Each clamping assembly includes a first clamping block 3 and a second clamping block 5. Limiting grooves 302 are provided on both sides of the first clamping block 3 and the second clamping block 5, allowing the side wall of the chuck body 1 to engage with the limiting grooves 302. The first clamping block 3 and the second clamping block 5 can move within the sliding grooves 101 through the limiting grooves 302.

[0031] A fixing rod 8 is coaxially fixedly connected inside the chuck body 1. A double-threaded rod 10 has a through hole in its middle. The double-threaded rod 10 is slidably connected to the outside of the fixing rod 8 through the through hole, so that the double-threaded rod 10 is coaxially set inside the chuck body 1. Since the double-threaded rod 10 can slide outside the fixing rod 8, its position can be flexibly adjusted, thereby changing the position of the first clamping block 3 and the second clamping block 5 as a whole, which facilitates the device to clamp and fix pipe fittings 4 of different diameters.

[0032] For example, refer to Figure 4 The position of the double-threaded rod 10 is moved to the right, thereby causing the first clamping block 3 and the second clamping block 5 to move outward as a whole through the first connecting rod 601 and the second connecting rod 701, so that the first clamping block 3 and the second clamping block 5 can clamp and fix the pipe 4 with a larger diameter.

[0033] The double-ended threaded rod 10 has threaded grooves at both ends, and the thread directions of the threaded grooves at both ends are opposite. The first threaded sleeve 6 and the second threaded sleeve 7 are respectively disposed at the two ends of the double-ended threaded rod 10. When the double-ended threaded rod 10 rotates, the threaded grooves at both ends with opposite thread directions cause the first threaded sleeve 6 and the second threaded sleeve 7 to move away from each other.

[0034] Each clamp assembly also includes a first connecting rod 601 and a second connecting rod 701. The first connecting rod 601 is disposed between the first threaded sleeve 6 and the first clamping block 3, and the second connecting rod 701 is disposed between the second threaded sleeve 7 and the second clamping block 5. When the first threaded sleeve 6 and the second threaded sleeve 7 move away from each other, the first connecting rod 601 pulls the first clamping block 3, and the second connecting rod 701 pushes the second clamping block 5, thereby bringing the first clamping block 3 and the second clamping block 5 closer together to clamp the pipe fitting 4. The first clamping block 3 and the second clamping block 5 are located outside and inside the pipe fitting 4, respectively, which effectively prevents the pipe fitting 4 from being deformed while firmly clamping and fixing the pipe fitting 4.

[0035] In some embodiments, a first rubber strip 301 is provided on the side of the first clamping block 3 and the second clamping block 5 that are close to each other. When clamping and fixing the pipe 4, the first rubber strip 301 can deform in contact with the pipe 4, thereby providing a certain vibration reduction effect.

[0036] The inner walls on both sides of the limiting groove 302 are provided with second rubber strips 303. Since the first clamping block 3 and the second clamping block 5 slide inside the slide groove 101 through the limiting groove 302, the second rubber strips 303 on the inner wall of the limiting groove 302 can fill the sliding gap between the clamping block and the chuck body 1, thereby improving the stability of the first clamping block 3 and the second clamping block 5 and effectively reducing the vibration of the first clamping block 3 and the second clamping block 5.

[0037] In some embodiments, to facilitate adjustment of the first clamping block 3 and the second clamping block 5, a gear post 9 is fixedly connected to one end of the double-ended threaded rod 10. Fixed cylinders 12 are fixedly connected to the top and bottom ends of the chuck body 1. The upper and lower ends of the rack 11 are slidably connected to the interiors of the two fixed cylinders 12, respectively, and the rack 11 meshes with the gear post 9. A screw 2 is rotatably connected to the top of the chuck body 1. A threaded hole is provided at the upper end of the rack 11, and the lower end of the screw 2 is threadedly connected to the rack 11 through the threaded hole. Rotating the screw 2 causes the rack 11 to slide up and down inside the fixed cylinder 12, thereby rotating the gear post 9 and causing the double-ended threaded rod 10 to rotate, thus driving the first clamping block 3 and the second clamping block 5 to clamp and fix the pipe fitting 4.

[0038] In some embodiments, the upper end of the screw 2 is provided with a hexagonal groove. The hexagonal groove allows for easy rotation of the screw 2 using a hexagonal wrench, thereby adjusting the first clamping block 3 and the second clamping block 5.

[0039] In some embodiments, one end of the double-ended threaded rod 10 is provided with a linear drive structure, such as a linear motor, an electric push rod, or other drive components. The double-ended threaded rod 10 can be pushed to one side by the linear drive structure, causing the first clamping block 3 and the second clamping block 5 to move inward as a whole, thereby clamping and fixing workpieces of other shapes between the second clamping blocks 5.

[0040] The working principle of this chuck anti-vibration reinforcement clamp is as follows: the first clamping block 3 and the second clamping block 5 are located outside and inside the pipe fitting 4, respectively. Then, the screw 2 is rotated by a hex wrench. The screw 2 drives the rack 11 to slide upward inside the fixed cylinder 12, thereby driving the gear column 9 to rotate, causing the double-ended threaded rod 10 to rotate. The first threaded sleeve 6 and the second threaded sleeve 7 on the outside of the double-ended threaded rod 10 move away from each other. The first connecting rod 601 pulls the first clamping block 3, and the second connecting rod 701 pushes the second clamping block 5, thereby bringing the first clamping block 3 and the second clamping block 5 closer together to clamp the pipe fitting 4. Since the first clamping block 3 and the second clamping block 5 are located outside and inside the pipe fitting 4, respectively, it effectively avoids deformation of the pipe fitting 4 while firmly clamping and fixing the pipe fitting 4.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
