Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a cutting device for mechanical parts. Background Technology

[0002] In the field of mechanical parts manufacturing, cutting is a common and crucial step. Traditional mechanical parts cutting devices often have several shortcomings. Firstly, when clamping mechanical parts, most devices can only provide simple fixation for parts of a single shape, such as using conventional arc-shaped clamps for round parts. However, for rectangular or other angular parts, they lack precise positioning and stable clamping structures. This leads to easy displacement or wobbling of the parts during cutting, severely affecting cutting accuracy and failing to meet the requirements of modern high-precision manufacturing. Secondly, controlling the cutting length largely relies on manual measurement and rough positioning, lacking a precise and automated length positioning system. Operators determine the cutting position by visual observation and manual operation, which is not only inefficient but also prone to errors, making it difficult to ensure the consistency of cutting lengths in mass production. These problems, to some extent, restrict the improvement of production efficiency and product quality in the machining industry. Utility Model Content

[0003] The purpose of this invention is to provide a mechanical parts cutting device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A mechanical parts cutting device includes a positioning frame, a cutting assembly, a fixed clamping assembly, and a movable clamping assembly. The fixed clamping assembly is used to maintain the mechanical parts in a fixed state during the cutting process, and the movable clamping assembly is used to move the mechanical parts to adjust their cutting length.

[0006] One side of the movable clamping assembly is provided with a length positioning frame that is slidably connected to the upper surface of the positioning frame. An infrared sensor is fixedly connected to one side of the length positioning frame. The movable clamping assembly includes a movable frame that is slidably connected to the upper surface of the positioning frame. An upper clamping arc plate and a lower clamping arc plate that are movably connected to each other are provided on the inner wall of the movable frame. A right-angle positioning groove is provided on the inner wall of both the upper clamping arc plate and the lower clamping arc plate.

[0007] A drive assembly for lateral movement is provided below the movable clamping assembly. A length scale bar is fixedly connected to one side of the positioning frame, and a positioning plate is fixedly connected to one end of the lower clamping arc plate.

[0008] A further improvement of the present invention is that the driving component includes a threaded rod, the outer wall of which is threadedly connected to a support base, the upper surface of which is fixedly connected to the moving frame, the outer wall of which is slidably connected to the inner wall of the positioning frame, and a reduction motor is fixedly connected to one end of the threaded rod.

[0009] A further improvement of this utility model is that: one end of the support base is provided with a threaded hole for adapting to the threaded rod, and the inner wall of the threaded hole is threadedly connected to the outer wall of the threaded rod.

[0010] A further improvement of this utility model is that: guide grooves are provided on both sides of the positioning frame, and the inner wall of the length positioning frame near the bottom is slidably connected to the inner wall of the guide groove through a slider.

[0011] A further improvement of this utility model is that the fixing clamping assembly is fixedly connected to the upper surface of the positioning frame.

[0012] A further improvement of this utility model is that a hydraulic rod is fixedly connected to the upper surface of the upper clamping arc plate, and a spring buffer rod is movably sleeved on one side of the upper clamping arc plate through a mounting frame plate.

[0013] A further improvement of this utility model is that the cutting component is located between the fixed clamping component and the movable clamping component.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a mechanical parts cutting device. The movable clamping component and the fixed clamping component cooperate through the upper clamping arc plate and the lower clamping arc plate. It can firmly clamp mechanical parts with different cross-sectional shapes (rectangular parts can be accurately positioned using right-angle positioning slots, and circular parts can be directly clamped), effectively ensuring the stability of the parts during the cutting process and improving the cutting accuracy.

[0016] This utility model provides a mechanical parts cutting device. By utilizing the coordinated work of a length positioning frame, a length scale bar, an infrared sensor, and a drive assembly (a geared motor and a threaded rod), the cutting length of the mechanical parts can be accurately set and controlled. The movement of the moving clamping assembly is stopped in a timely manner by the feedback signal of the infrared sensor to ensure that the cutting length meets the requirements.

[0017] This utility model provides a mechanical parts cutting device. The fixed clamping component and the movable clamping component have similar structures and can adapt to the clamping needs of mechanical parts of various lengths. The length positioning frame can be connected to an external telescopic rod to realize automatic drive lateral movement, which further improves the automation level and flexibility of the device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-4 As shown, this utility model provides a mechanical parts cutting device, including a positioning frame 1, a cutting component 2, a fixed clamping component 3 and a movable clamping component 4. The fixed clamping component 3 is used to maintain the fixed state of the mechanical parts during the cutting process, and the movable clamping component 4 is used to move the mechanical parts to adjust their cutting length.

[0026] A length positioning frame 7 is slidably connected to the upper surface of the positioning frame 1 on one side of the movable clamping assembly 4. An infrared sensor 9 is fixedly connected to one side of the length positioning frame 7. The movable clamping assembly 4 includes a movable frame 19 slidably connected to the upper surface of the positioning frame 1. An upper clamping arc plate 11 and a lower clamping arc plate 12 are movably connected to each other on the inner wall of the movable frame 19. A right-angle positioning groove 17 is opened on the inner wall of both the upper clamping arc plate 11 and the lower clamping arc plate 12.

[0027] A drive assembly for lateral movement is provided below the movable clamping assembly 4. A length scale bar 10 is fixedly connected to one side of the positioning frame 1, and a positioning plate 13 is fixedly connected to one end of the lower clamping arc plate 12.

[0028] The drive assembly includes a threaded rod 5, with a support base 14 threadedly connected to the outer wall of the threaded rod 5. The upper surface of the support base 14 is fixedly connected to the moving frame 19, and the outer wall of the support base 14 is slidably connected to the inner wall of the positioning frame 1. A reduction motor 6 is fixedly connected to one end of the threaded rod 5.

[0029] One end of the support base 14 is provided with a threaded hole 16 for fitting the threaded rod 5, and the inner wall of the threaded hole 16 is threadedly connected to the outer wall of the threaded rod 5.

[0030] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, guide grooves 8 are provided on both sides of the positioning frame 1, and the inner wall of the length positioning frame 7 near the bottom is slidably connected to the inner wall of the guide groove 8 by a slider.

[0031] The fixed clamping assembly 3 is fixedly connected to the upper surface of the positioning frame 1.

[0032] A hydraulic rod 15 is fixedly connected to the upper surface of the upper clamping arc plate 11, and a spring buffer rod 18 is movably sleeved on one side of the upper clamping arc plate 11 through a mounting frame plate.

[0033] The cutting component 2 is located between the fixed clamping component 3 and the movable clamping component 4.

[0034] The working principle of this mechanical parts cutting device will be explained in detail below.

[0035] like Figures 1-4As shown, when cutting long rod-shaped mechanical parts, the part is first passed through the fixed clamping assembly 3 and one end is abutted against the positioning plate 13. At this time, the hydraulic rod 15 in the movable clamping assembly 4 is activated, which pushes the upper clamping arc plate 11 to clamp and fix the rod-shaped part. When the cross-section of the rod-shaped part is rectangular, its diagonal is aligned with the right-angle positioning groove 17, so that the upper clamping arc plate 11 and the lower clamping arc plate 12 can firmly clamp it. When the cross-section of the rod-shaped part is circular, it can be directly clamped and fixed using the upper clamping arc plate 11 and the lower clamping arc plate 12.

[0036] After the moving clamping assembly 4 has clamped the rod-shaped part, the length positioning frame 7 is pulled to move on the positioning frame 1. The distance that the length positioning frame 7 moves is matched with the value of the length to be cut of the rod-shaped part by means of the scale on the length scale bar 10.

[0037] Once the length positioning frame 7 is in place, the infrared sensor 9 is connected to an external controller, and the reduction motor 6 is started, causing the threaded rod 5 to rotate. During the rotation of the threaded rod 5, the support base 14 moves forward, which in turn moves the moving clamping assembly 4 forward. When the moving clamping assembly 4 moves to the position defined by the length positioning frame 7, the infrared light emitted by the infrared sensor 9 is blocked by the positioning plate 13, and the infrared sensor 9 feeds back the signal to the controller, which then controls the reduction motor 6 to stop. At this point, the distance that the moving clamping assembly 4 has moved along the rod-shaped component is exactly the distance defined by the length positioning frame 7.

[0038] Then, the hydraulic rod 15 in the clamping assembly 3 is activated to clamp and fix the rod-shaped parts, and then the cutting assembly 2 is activated to perform the cutting work.

[0039] The length positioning frame 7 can be driven to move laterally by an external telescopic rod, automatically completing the distance limiting work.

[0040] The fixed clamping assembly 3 has the same structure as the movable clamping assembly 4, except that the lengths of the upper clamping arc plate 11 and the lower clamping arc plate 12 are different from those in the fixed clamping assembly 3.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
