Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a deburring device for the surface of a scratch-resistant cylinder. Background Technology

[0002] Cylindrical workpieces are widely used in machinery manufacturing, chemical storage and transportation, and metallurgical equipment. During the processing and forming of cylindrical bodies, burrs are often generated on their surfaces or edges. If these burrs are not removed in time, they will affect the assembly accuracy and service life of the cylindrical body, and may even cause poor sealing or safety hazards.

[0003] In existing technologies, common methods for deburring cylinders mainly involve manual grinding or mechanical grinding using grinding blocks mounted on a rotating ring. For example, some devices employ a single rotating ring structure with grinding blocks distributed circumferentially. When the ring rotates, the grinding blocks contact the cylinder surface to achieve deburring. However, such structures have the following drawbacks: Uneven grinding: In existing devices, the grinding blocks are mostly fixed on a single rotating ring, and the grinding direction is relatively uniform, resulting in uneven distribution of force on the cylinder surface. This can easily lead to insufficient or excessive grinding in certain areas, resulting in unsatisfactory deburring effect.

[0004] It can easily cause surface scratches: The grinding blocks of some existing devices are rigidly fixed to the rotating ring or support, which lacks flexible adjustment during the grinding process. This causes the grinding blocks to make hard contact with the cylinder surface, which can easily produce scratches or indentations, thus affecting the smoothness of the cylinder surface and its performance.

[0005] Insufficient guiding stability: In existing technologies, the limiting and guiding of the cylinder usually relies on simple support rollers, which lack a fitting structure that matches the outer wall of the cylinder. This can easily cause the cylinder to deviate during the grinding process, thereby affecting the accuracy and stability of deburring.

[0006] In summary, existing cylinder deburring devices still have shortcomings in terms of grinding uniformity, scratch resistance, and guiding stability. There is an urgent need to propose a new structural design to solve the above problems and improve the overall deburring effect of cylinders. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a deburring device for a scratch-resistant cylinder surface, comprising a fixing frame, a rotary grinding assembly, a guide assembly, and a drive motor. The fixing frame includes opposing side plates, and the rotary grinding assembly is rotatably mounted on the side plates; the guide assembly is disposed on the outside of the rotary grinding assembly for guiding and limiting the cylinder; the drive motor meshes with the rotary grinding assembly through a worm shaft to drive the rotary grinding assembly to rotate, thereby achieving deburring of the cylinder surface.

[0009] In a preferred embodiment, the rotary grinding assembly includes a first rotating ring rotatably mounted on the surfaces of two side plates and a second rotating ring coaxially arranged therewith. Both the first and second rotating rings have several support bars on their inner sides, and grinding blocks are fixedly mounted on the support bars. Specifically, after the drive motor starts, the first and second rotating rings rotate synchronously, driving the grinding blocks on the support bars to perform circumferential grinding on the outer surface of the cylinder, effectively removing surface burrs and achieving efficient processing.

[0010] In a preferred example, the support bars are arranged in an oblique arc shape, and the oblique directions of the inner support bars of the first and second rotating rings are opposite. Specifically, this structure enables the cylinder to be subjected to cutting forces in different directions simultaneously during the grinding process, which compensate for grinding deviations, thereby improving the uniformity of deburring and avoiding insufficient or excessive grinding in certain areas.

[0011] In a preferred embodiment, the grinding blocks are arranged at intervals along the circumferential direction of the first and second rotating rings. Specifically, this arrangement ensures that the grinding blocks are evenly distributed in a circumferential direction, guaranteeing that the surface of the cylinder receives continuous and uniform friction during rotation, thereby improving deburring efficiency and processing consistency.

[0012] In a preferred embodiment, the guiding assembly includes a roller frame and an abutment roller mounted on the roller frame, the abutment roller abutting against the outer surface of the cylinder. Specifically, the abutment roller plays a limiting and guiding role during the rotation of the cylinder, preventing radial or axial displacement of the cylinder and ensuring that the cylinder remains in a stable position during grinding.

[0013] In a preferred example, there are two or more abutment rollers, symmetrically distributed on both sides of the rotary grinding assembly. Specifically, the guiding stability of the cylinder is improved by multi-point limiting, preventing the cylinder from shaking during deburring; at the same time, the abutment roller surface has arc-shaped grooves arranged in a circular pattern along the circumference, which can fit against the cylinder surface, playing a clamping and guiding role, further improving processing stability.

[0014] In a preferred embodiment, the drive motor is fixed to one side of the mounting bracket by a sliding installation, which can be adjusted according to the position of the side plate. Specifically, this structure facilitates the adjustment of the relative position between the drive motor and the worm shaft, ensuring stable meshing between the worm shaft and the external gear ring, and enhancing the adaptability and reliability of the device.

[0015] In a preferred embodiment, the support bar, the first rotating ring, and the second rotating ring are integrally formed, and the support bar is in the form of an elastic sheet. Specifically, this design not only improves the overall structural strength but also allows the grinding block to undergo moderate elastic deformation when in contact with the cylinder, ensuring a flexible fit between the grinding block and the cylinder surface, thereby avoiding scratches on the cylinder surface caused by hard friction and ensuring a scratch-resistant effect.

[0016] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting a first rotating ring and a second rotating ring, and installing several support bars and grinding blocks on their inner sides, continuous circumferential grinding of the cylinder surface can be achieved after the drive motor drives the worm shaft to rotate, effectively removing burrs and improving deburring efficiency. The support bars are arranged in an oblique arc shape, and the support bars of the first rotating ring and the second rotating ring are in opposite directions, so that the grinding effects compensate for each other, further improving the uniformity of deburring.

[0017] 2. In this utility model, the support bar is integrally formed with the first rotating ring and the second rotating ring, and has an elastic sheet-like structure. During the grinding process, it can ensure that the grinding block and the surface of the cylinder remain in flexible contact, avoiding hard friction that could cause scratches on the surface of the cylinder, thereby achieving a scratch-resistant effect.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a deburring device for scratch-resistant cylinder surfaces.

[0023] Combination Figures 1-5 As shown, the present invention provides a deburring device for the surface of a scratch-resistant cylinder, including a fixing frame 100, a grinding assembly 200, a guiding assembly 300, and a drive motor 400 slidably mounted on one side of the fixing frame 100.

[0024] The fixed frame 100 has side plates 110 arranged opposite to each other on both sides, and the rotary grinding assembly 200 is rotatably mounted on the surface of the side plates 110.

[0025] The grinding assembly 200 includes a first rotating ring 210 rotatably mounted on the surfaces of two side plates 110 and a second rotating ring 220 coaxially arranged therewith. Both the first and second rotating rings 210 have several support strips 211 on their inner sides, and grinding blocks 212 for grinding the cylinder surface are mounted on the support strips 211. The support strips 211 are arranged in an oblique arc shape, and the oblique directions of the support strips 211 on the inner sides of the first and second rotating rings 210 are opposite, thereby achieving complementary grinding during operation and improving the uniformity and efficiency of deburring. Both the first and second rotating rings 210 and 220 have external toothed rings 230 fixed to their outer circumferences for meshing with the worm shaft 410.

[0026] In this embodiment, the guiding assembly 300 includes a roller frame 310 and an abutment roller 320 rotatably mounted on the roller frame 310 in a circumferential arrangement. The abutment roller 320 abuts against the outer surface of the cylinder to limit and guide the position of the cylinder, preventing the cylinder from shifting during the deburring process. Furthermore, the abutment roller 320 has an arc-shaped groove on its surface, arranged circumferentially, which allows it to adhere to the outer wall of the cylinder and guide the movement of the cylinder, thereby avoiding scratches on the cylinder surface due to shifting.

[0027] In this embodiment, the output end of the drive motor 400 is connected to a worm shaft 410 rotatably mounted on the surface of the side plate 110. The worm shaft 410 meshes with the outer gear ring 230 on the outer periphery of the first rotating ring 210 and the second rotating ring 220, and is used to drive the grinding assembly 200 to rotate, thereby achieving deburring treatment on the surface of the cylinder. The drive motor 400 is fixed to one side of the fixing frame 100 by sliding installation and can be adjusted according to the position of the side plate 110 to ensure that the drive motor 400 and the worm shaft 410 are in a reasonable position.

[0028] During operation, after the drive motor 400 starts, it drives the worm shaft 410 to rotate. The worm shaft 410 meshes with the external gear ring 230, driving the first rotating ring 210 and the second rotating ring 220 to rotate. As they rotate, the grinding block 212 mounted on the support bar 211 rubs against the surface of the cylinder in a circumferential manner, thereby removing burrs from the surface of the cylinder. Since the support bar 211 is integrally formed with the first rotating ring 210 and the second rotating ring 220 and has an elastic sheet structure, the grinding block 212 can produce appropriate elastic deformation when it comes into contact with the surface of the cylinder, ensuring that the grinding block 212 flexibly adheres to the surface of the cylinder and avoiding scratches.

[0029] Meanwhile, the anti-roller 320 in the guide component 300 keeps in contact with the surface of the cylinder, playing a limiting and guiding role, so that the cylinder maintains a stable position and rotation trajectory during the grinding process, thereby further ensuring the uniformity and stability of the deburring effect.

[0030] In summary, this utility model achieves efficient, uniform, and scratch-free deburring of the cylinder surface through the coordinated operation of components such as the first rotating ring 210, the second rotating ring 220, the grinding block 212, the abutment roller 320, and the drive motor 400.

[0031] Working principle and usage process of this utility model: This invention achieves deburring of the cylinder surface through the coordinated operation of the grinding assembly 200, the guide assembly 300, and the drive motor 400, which are set in the fixed frame 100.

[0032] The drive motor 400 drives the worm shaft 410 to rotate through its output end. The worm shaft 410 meshes with the external toothed ring 230 provided on the outer periphery of the first rotating ring 210 and the second rotating ring 220, thereby driving the first rotating ring 210 and the second rotating ring 220 and their surface guiding components 300 to rotate, so as to realize the circumferential movement of the first rotating ring 210, the second rotating ring 220 and their surface guiding components 300 on the surface of the cylinder to be processed.

[0033] The inner sides of the first rotating ring 210 and the second rotating ring 220 are provided with a plurality of support strips 211, and grinding blocks 212 are mounted on the support strips 211. As the rotating rings rotate, the grinding blocks 212 continuously circumferentially rub the cylinder surface that is in close contact with their outer sides, which can effectively remove burrs. The support strips 211 are arranged in an oblique arc shape, and the support strips 211 of the first rotating ring 210 and the second rotating ring 220 are in opposite directions, so that the grinding effects compensate for each other and improve the uniformity of deburring.

[0034] The guide assembly 300 includes a roller frame 310 and a stop roller 320. The stop roller 320 contacts the surface of the cylinder to form a positioning limit, preventing the cylinder from shifting radially or axially during the deburring process. The surface of the stop roller 320 has an arc-shaped groove arranged in a circumferential direction, which can fit against the outer wall of the cylinder and guide the rotational movement of the cylinder, thereby avoiding scratches caused by shifting during the grinding process.

[0035] The support bar 211 is integrally formed with the first rotating ring 210 and the second rotating ring 220, and has certain elastic sheet-like characteristics. When the grinding block 212 comes into contact with the cylinder, it can produce a small amount of elastic deformation, thereby ensuring that the grinding block 212 and the cylinder surface remain in flexible contact and avoiding hard friction that causes scratches on the cylinder surface.
