Description

Technical Field

[0001] This utility model relates to the field of rubber bushing cutting technology, and in particular to a rubber bushing cutting device. Background Technology

[0002] In the processing and production of rubber bushings, the cutting process is one of the key steps. Typically, a cutting machine is used to vertically cut the entire rubber bushing to the specified length, thus dividing the bushing into two semi-finished products that meet standard dimensions.

[0003] However, most rubber bushings are currently cut directly with blades. Because the rubber bushing has a hollow structure inside, it will deform under the pressure when it comes into contact with the blade. This deformation will cause the cut surface to be uneven, which will affect the flatness of the cut, produce a large dimensional error, and ultimately result in low cutting accuracy.

[0027] Reference Figures 1-4 As shown, this utility model embodiment provides a rubber bushing cutting device, including a base 1, a support seat 2 fixedly connected to the upper end of the base 1, and a rotating shaft 3 rotatably connected inside the support seat 2, the rotating shaft 3 being used to support the rubber bushing; it also includes:

[0028] Fixing mechanism 4 is located on the left side of support base 2 and serves to fix the support rubber bushing.

[0029] Limiting mechanism 5 is set between support base 2 and fixing mechanism 4. Limiting mechanism 5 is used to adjust the length of the support rubber bushing cut.

[0030] Drive mechanism 6 is located on the upper end of support base 2 and is used to drive the rotating shaft 3 to rotate.

[0031] The cutting mechanism 7 is located at the left end of the fixing mechanism 4 and is used to cut the rubber bushing. During operation, the fixing mechanism 4 firmly clamps the rubber bushing to prevent deformation or displacement due to its hollow internal structure during cutting. Before clamping, the limiting mechanism 5 can be precisely adjusted according to the required cutting length to ensure the accuracy of the cutting dimensions. The driving mechanism 6 drives the rotating shaft 3 to rotate smoothly, so that the rubber bushing rotates at a uniform speed during cutting, further improving the uniformity and stability of the cutting. Finally, driven by the electric push rod, the cutting mechanism 7 drives the cutting blade 74 to precisely cut into the rubber bushing, completing the cutting operation. The entire device has a reasonable structure and is easy to operate. It effectively solves the problems of poor flatness and low precision in existing cutting methods, and significantly improves the cutting quality and production efficiency of rubber bushings.

[0032] In a further embodiment, refer to Figure 2 The fixing mechanism 4 includes a slider 41 and a first electric push rod 43. Limiting grooves 31 are equidistantly provided on the side wall of the rotating shaft 3. The multiple limiting grooves 31 are interconnected. Multiple sliders 41 are provided and are slidably connected inside the limiting grooves 31. A fixing ring 47 is fixedly connected to the ends of the multiple sliders 41 away from the axis of the rotating shaft 3. A connecting ring 42 is rotatably connected to the side wall of the fixing ring 47. The first electric push rod 43 is fixedly connected inside the support base 2. The output shaft end of the first electric push rod 43 is fixedly connected to the right end of the connecting ring 42. The left ends of the multiple sliders 41 are rotatably connected to a first connecting rod 44. The right end of the first connecting rod 44 abuts against the left end of the slider 41. A second connecting rod 46 is rotatably connected inside the left side of the limiting groove 31. The left end of the second connecting rod 46 abuts against the inner wall of the limiting groove 31. The ends of the first connecting rod 44 and the second connecting rod 46 away from the axis of the rotating shaft 3 are rotatably connected by a support rod 45.

[0033] In this embodiment, the fixed mechanism 4 achieves stable clamping and precise positioning of the rubber bushing. Specifically, the output shaft of the first electric push rod 43 extends, driving the connecting ring 42 to move. The movement of the connecting ring 42 drives the fixed ring 47 to move, thereby causing multiple sliders 41 to slide within the limiting groove 31. This, in turn, causes the support rod rotatably connected between the first connecting rod 44 and the second connecting rod 46 to expand outward. The expanded support rod 45 then fixes the rubber bushing. The extension and retraction of the first electric push rod 43 provides power for the movement of the sliders 41, allowing the fixed mechanism 4 to be flexibly adjusted according to rubber bushings of different sizes.

[0034] In a further embodiment, refer to Figure 3The limiting mechanism 5 includes a second electric push rod 51 and a limiting plate 53. Multiple limiting grooves 31 are slidably connected to limiting blocks 52. The limiting plate 53 is rotatably connected to the outer wall of the limiting block 52. The second electric push rod 51 is fixedly connected to the upper end of the base 1 through a fixed seat and is located on the right side of the support base 2. The rotating shaft 3 has a through hole 32 on its end face. The through hole 32 is connected to the limiting groove 31. The left end of the second electric push rod 51 passes through the through hole 32. The output shaft end of the second electric push rod 51 passes through the limiting block 52 and is rotatably connected to it. The first electric push rod 43 passes through the limiting plate 53 and is slidably connected to it.

[0035] In this embodiment, the precise adjustment of the cutting length of the rubber bushing is achieved through the cooperation of the second electric push rod 51 and the limiting plate 53. The extension and retraction of the second electric push rod 51 can push the limiting block 52 to slide within the limiting groove 31, thereby driving the limiting plate 53 to move, thus precisely controlling the cutting position of the rubber bushing. In addition, the design of the first electric push rod 43 passing through the limiting plate 53 and slidingly connecting with it makes the operation of the limiting mechanism 5 smoother. This design of the limiting mechanism 5 not only improves the accuracy of the cutting size, but also optimizes the operation process, reduces the error of manual adjustment, and improves production efficiency and product quality.

[0036] In a further embodiment, refer to Figure 3 The drive mechanism 6 includes a first motor 61 and a second gear 63. The first motor 61 is fixedly connected to the upper end of the support base 2. The first gear 62 is fixedly connected to the output shaft end of the first motor 61. The second gear 63 is fixedly connected to the side wall of the rotating shaft 3. The first gear 62 and the second gear 63 mesh with each other.

[0037] In this embodiment, the smooth and precise drive of the rotating shaft 3 is achieved through the meshing transmission of the first motor 61 with the first gear 62 and the second gear 63. This gear transmission method ensures that the rotating shaft 3 maintains a uniform rotation speed during the cutting process, thereby improving the uniformity and stability of the rubber bushing cutting. At the same time, the precise control capability of the first motor 61 allows the rotation speed of the rotating shaft 3 to be flexibly adjusted according to the cutting requirements, further optimizing the cutting effect. In addition, this transmission structure is simple, reliable, and easy to maintain, which can effectively reduce the operating cost of the equipment and improve production efficiency.

[0038] In a further embodiment, refer to Figure 4 The cutting mechanism 7 includes a mounting frame 71 and a third electric push rod 72. The mounting frame 71 is fixedly connected to the upper end of the base 1, and the third electric push rod 72 is fixedly connected to the upper end of the mounting frame 71. The output shaft below the third electric push rod 72 is fixedly connected to a second motor 73, and the output shaft end of the second motor 73 is fixedly connected to a cutting blade 74. The cutting blade 74 is located above the left side of the rotating shaft 3.

[0039] In this embodiment, the cutting mechanism 7 enables efficient and precise cutting of the rubber bushing. The extension and retraction of the third electric push rod 72 precisely controls the up-and-down movement of the cutting blade 74, ensuring that the cutting blade 74 accurately cuts into the predetermined position of the rubber bushing. The high-speed rotation of the second motor 73 provides strong power to the cutting blade 74, enabling it to complete the cutting operation quickly and smoothly. The mounting bracket 71 provides stable support for the entire cutting mechanism 7, ensuring that the movement trajectory of the blade remains accurate during the cutting process and avoiding cutting errors caused by vibration or shaking. In addition, the design of the cutting blade 74 located on the upper left side of the rotating shaft 3 makes the cutting process smoother and facilitates the operator to observe and control the cutting progress. This design of the cutting mechanism 7 not only improves cutting efficiency but also significantly enhances cutting quality, reduces the defect rate caused by uneven cutting, and further optimizes the production process of the rubber bushing.
