Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a chuck device for a machine tool used for machining mechanical parts. Background Technology

[0002] Chucks play a crucial role in machining, primarily by fixing the workpiece and ensuring stability and precision during processing. As production demands evolve, chucks continue to develop, providing more efficient and precise solutions. Modern chucks not only improve production efficiency but also effectively guarantee machining accuracy, demonstrating significant advantages, especially in mass production. In the future, chucks will trend towards intelligence and automation, incorporating advanced technologies to achieve adaptive adjustments to meet increasingly complex machining requirements. Simultaneously, with the increasing demand for green manufacturing, chucks will develop towards greater environmental friendliness and energy efficiency. Overall, the development of chucks will propel the machining industry towards greater efficiency, precision, and intelligence.

[0003] A search revealed an existing patent (publication number: CN220698267U) disclosing a chuck device for a machine tool, belonging to the field of machine tool chuck technology. This utility model includes a chuck body and jaws. The chuck body has a cross groove inside, and the jaws are slidably connected to the cross groove. A sliding block is fixedly connected to the upper wall of the jaws, and an anti-slip block is fixedly connected to the side wall of the jaws. A lubrication device is fixedly connected to the upper end of the chuck body. Through the coordinated use of the handwheel, limit bolt, lubrication device, lead screw, and limit block, the workpiece can be clamped and released by rotating the handwheel, which is convenient and eliminates the need to switch tools back and forth. This avoids the inconvenience of adjustment when the chuck installation space is small. When the sliding block presses against the pressure block during movement, multiple guide pipes and nozzles simultaneously spray lubricating oil onto the jaws, reducing the frictional resistance between the jaws and the chuck body, reducing noise, facilitating jaw adjustment by operators, and increasing the service life of the chuck.

[0004] However, in actual use, the above-mentioned solution lacks automatic part correction functionality. This necessitates manual adjustment of part positions by the operator, increasing the need for manual intervention and raising the risk of human error, thereby extending processing time and reducing production efficiency. Due to the lack of automatic correction, chuck clamping is unstable, potentially causing minor displacement or vibration of parts during processing, thus affecting processing quality. Frequent manual adjustments also accelerate the wear of the chuck and clamping device, increasing the equipment maintenance burden. Furthermore, due to its lack of flexibility, the chuck cannot quickly adapt to the processing requirements of different parts, limiting production flexibility and efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the lack of automatic correction function for parts in the existing technology increases the risk of human error, and may also cause slight displacement or vibration of parts during processing, thereby affecting the processing quality. Therefore, a chuck device for machine tools for machining mechanical parts is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A chuck device for a machine tool used for machining mechanical parts includes a base plate and further includes:

[0008] Limiting components are symmetrically arranged on both sides of the top of the base plate;

[0009] The support components are located at the top middle section of the base plate;

[0010] The correction component is located on top of the support component;

[0011] A limiting sleeve is installed at the bottom of the lifting end of the support assembly;

[0016] As a preferred technical solution of this application, the clamping assembly includes a hinge frame uniformly fixed to the outer wall of the limiting sleeve, a second hydraulic rod rotatably connected to the outer side of the hinge frame, a clamping arm rotatably connected to the output end of the second hydraulic rod, and the middle section of the clamping arm rotatably connected to the lifting plate.

[0017] As a preferred technical solution of this application, a third hydraulic rod is fixedly connected to the middle section of the bottom of the lifting plate, and a limit ball is fixedly connected to the output end of the third hydraulic rod through the bottom plate. The limit ball is engaged with the bottom plate.

[0018] Compared with the prior art, the present invention provides a chuck device for a machine tool for machining mechanical parts, which has the following advantages:

[0019] 1. The chuck device of the machine tool for machining mechanical parts described in this utility model uses the weight of the workpiece itself to press down the lifting plate, while the limiting posts are limited by the second sliding grooves on both sides. The limiting posts on both sides move in opposite directions to squeeze and correct the workpiece. Then, the workpiece is clamped and fixed by the clamping components around the perimeter, realizing automatic correction, ensuring machining accuracy and reducing human error, avoiding manual intervention. Automated correction and clamping can reduce the adjustment time of parts, improve machining efficiency, and reduce machining time. At the same time, the uniform clamping force reduces chuck wear and extends the service life of the equipment. The stable fixation of the workpiece by clamping around the perimeter improves machining stability, prevents displacement or vibration, and ensures machining quality. This design is highly adaptable, can handle workpieces of different shapes and weights, and improves production safety and reduces operational hazards.

[0020] 2. The chuck device for a machine tool used for machining mechanical parts, as described in this utility model, moves a rubber ball via a first hydraulic rod, thereby adjusting the center point of the workpiece's correction position for precise correction, improving machining accuracy and stability. The automated design reduces manual intervention and errors, and the uniform force distribution prevents workpiece deformation, improving machining quality. It is highly adaptable, capable of handling workpieces of different shapes and weights, improving efficiency and extending equipment life. The overall design improves accuracy, efficiency, and equipment stability, making it a highly efficient and reliable solution. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, the chuck device of this machine tool for machining mechanical parts includes a base plate 1, and further includes: a limiting assembly, symmetrically arranged on both sides of the top of the base plate 1, which supports and limits the limiting assemblies on both sides through the base plate 1; a support assembly, arranged in the middle of the top of the base plate 1, which supports and limits the support assembly through the base plate 1; a correction assembly, arranged on top of the support assembly, which supports and limits the correction assembly through the support assembly; a limiting sleeve 21, arranged at the bottom of the lifting end of the support assembly, which supports the limiting sleeve 21 through the support assembly; and a clamping assembly, arranged outside the limiting sleeve 21, which supports and limits the clamping assembly through the limiting sleeve 21.

[0029] in,

[0030] like Figure 2 and Figure 3 As shown, the limiting component includes limiting frames 11 symmetrically fixed on both sides of the top of the base plate 1. The base plate 1 supports and fixes the limiting frames 11 on both sides simultaneously. A first sliding groove 12 is provided in the middle section of the limiting frame 11, which provides lifting space for the clamping component. A second sliding groove 13 is provided on both sides of the top of the base plate 1.

[0031] like Figure 1 and Figure 2 As shown, the support assembly includes a spring 2 fixed to the top middle section of the base plate 1. The base plate 1 supports and fixes the spring 2. A lifting plate 3 is fixedly connected to the top of the spring 2. The weight of the lifting plate 3 is slightly lower than the stress of the spring 2, so the spring 2 can support the lifting plate 3. However, if a workpiece is placed on the top of the lifting plate 3, the weight of the workpiece will press the lifting plate 3 down. The lifting plate 3 is slidably connected to the limiting frame 11, and the limiting frame 11 limits the lifting plate 3.

[0032] like Figure 1 and Figure 4As shown, the correction assembly includes symmetrically fixed slide rails 31 on both sides of the top of the lifting plate 3. The lifting plate 3 supports and fixes the slide rails 31 on both sides. Slider 32 is symmetrically slidably connected to the top of the slide rails 31, limiting the slider 32. Limiting post 33 is fixedly connected to the top of the slider 32, supporting and fixing the limiting post 33. A first hydraulic rod 34 is fixedly connected to the inner side of the limiting post 33, supporting and fixing the first hydraulic rod 34. The limiting post 33 is slidably connected to the second slide groove 13, adjusting the lifting angle of the limiting post 33 through the second slide groove 13. A rubber ball 35 is fixedly connected to the output end of the first hydraulic rod 34, supporting and fixing the rubber ball 35. At the same time, the first hydraulic rod 34 drives the rubber ball 35 to move laterally, thereby adjusting the position of the center point of the correction.

[0033] like Figure 2 As shown, the clamping assembly includes hinge frames 4 uniformly fixed to the outer wall of the limiting sleeve 21. The limiting sleeve 21 supports and fixes multiple hinge frames 4 on the outer wall, and provides stress points for the hinge frames 4. A second hydraulic rod 41 is rotatably connected to the outside of the hinge frame 4. The bottom of the second hydraulic rod 41 is supported and limited by the hinge frame 4. A clamping arm 42 is rotatably connected to the output end of the second hydraulic rod 41. The end of the clamping arm 42 is limited by the second hydraulic rod 41. The middle section of the clamping arm 42 is rotatably connected to the lifting plate 3. The middle section of the clamping arm 42 is limited by the lifting plate 3.

[0034] A third hydraulic rod 5 is fixedly connected to the middle section of the bottom of the lifting plate 3. The lifting plate 3 supports and fixes the third hydraulic rod 5. The output end of the third hydraulic rod 5 passes through the base plate 1 and is fixedly connected to a limit ball 51. The third hydraulic rod 5 supports and fixes the limit ball 51. The limit ball 51 is engaged with the base plate 1. The third hydraulic rod 5 drives the limit ball 51 to retract in length, thereby fixing the distance between the base plate 1 and the lifting plate 3.

[0035] Specifically, when using the chuck device of this machine tool for machining mechanical parts: First, the workpiece is placed on top of the lifting plate 3. Then, the lifting plate 3 is pressed down to the bottom by the weight of the workpiece itself. During the process, the limiting posts 33 at the top of the lifting plate 3 are limited by the second sliding grooves 13 on both sides, so that the limiting posts 33 on both sides move in opposite directions to the inward side at the same time. At the same time, the rubber ball 35 on the outside of the first hydraulic rod 34 corrects the workpiece. When it is necessary to correct the workpiece with a page shape, it is only necessary to drive the rubber ball 35 to move laterally by the first hydraulic rod 34. The center point of the correction can be adjusted by extending and retracting the first hydraulic rod 34 at different positions by different distances.

[0036] After the correction is completed, the third hydraulic rod 5 drives the limit ball 51 to move to the top, thereby locking the base plate 1 through the limit ball 51, thus fixing the distance between the base plate 1 and the lifting plate 3.

[0037] Then, the second hydraulic rod 41 pushes the clamping arm 42 upward with the hinge frame 4 as the stress point, so that the clamping arm 42 rotates around the connection point between the clamping arm 42 and the lifting plate 3, thereby clamping and fixing the workpiece through the clamping arm 42.

[0038] 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.
