Description

Technical Field

[0001] This utility model relates to the field of diamond roller impact resistance technology, and in particular to an impact-resistant diamond roller. Background Technology

[0002] Diamond rollers, as a high-efficiency and high-precision dressing tool, are widely used in mass production in the automotive, bearing, and aerospace industries to precisely shape and dress grinding wheels to ensure the machining accuracy and surface quality of workpieces.

[0003] During operation, diamond rollers need to come into direct contact with high-speed rotating grinding wheels. This contact is accompanied by intense friction and continuous impact loads. To withstand this condition, existing diamond rollers rely on the rigidity and hardness of their matrix material to resist the impact. However, when encountering uneven grinding wheel surfaces and fluctuations in processing parameters, the instantaneous impact force generated can exceed the bearing limit of the matrix, causing the roller to undergo minor deformation or even structural damage, thereby affecting dressing accuracy and shortening the service life of the roller.

[0004] Meanwhile, the high-speed friction between the roller and the grinding wheel generates a lot of heat. If this heat cannot be removed in time and effectively, it will accumulate rapidly inside the roller, causing local overheating. High temperature will not only reduce the holding force between the diamond and the metal bond, which may cause the diamond to fall off prematurely, but it will also cause thermal expansion of the roller, damaging its existing dimensional accuracy. Existing external cooling methods are often unable to dissipate heat sufficiently in the core area of ​​the roller, and there is a bottleneck in heat dissipation efficiency.

[0005] Furthermore, as a high-value precision tool, the diamond layer on the working surface of diamond rollers is very fragile and extremely sensitive to collisions and drops. However, in actual production processes such as transportation, storage, and replacement, there is often a lack of specialized and highly protective packaging measures. This allows the rollers to be damaged by accidental impacts when not in use, resulting in huge economic losses.

[0006] Therefore, this utility model proposes an impact-resistant diamond roller to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of insufficient structural strength, weak impact resistance, difficulty in effectively dissipating heat generated during operation, and damage due to lack of special protection during transportation and storage in the existing technology of impact-resistant diamond rollers, this utility model aims to provide an impact-resistant diamond roller with an improved structure that can effectively solve the above problems.

[0008] This utility model provides an impact-resistant diamond roller, comprising: a main body, a base integrally formed with the main body, and a buffer mechanism.

[0009] The buffer mechanism includes a reinforcing rib disposed between the main body and the base, and the reinforcing rib has a hollow hole; the buffer mechanism also includes a conical hole disposed on the main body; the buffer mechanism also includes a buffer layer disposed on the outer periphery of the main body.

[0010] Furthermore, the buffer mechanism is disposed on the main body and the base, the reinforcing rib is disposed between the main body and the base, the tapered hole is opened on the main body near the reinforcing rib, and the buffer layer is disposed on the outer periphery of the main body, and the above structures are combined.

[0011] Preferably, the reinforcing ribs are distributed radially with the center of the main body as the center.

[0012] Preferably, the opening of the tapered hole has a tapered structure with an inner diameter that gradually decreases along the direction of coolant inflow.

[0013] Preferably, the buffer layer is made of a nickel-based alloy.

[0014] Preferably, the impact-resistant diamond roller further includes a packaging mechanism, which is detachably disposed outside the body and the substrate for accommodating and protecting the body and the substrate.

[0015] Preferably, the packaging mechanism includes a protective shell, on which a door panel is provided.

[0016] Preferably, the door panel is provided with clamps and latches, which are used to lock the door panel onto the protective shell.

[0017] Preferably, the protective shell has a retaining foam inside, which is used to clamp and fix the main body.

[0018] Preferably, the fixed foam is made of polyether polyurethane.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problems of insufficient structural strength, impact deformation, and difficulty in dissipating working heat in existing diamond rollers by setting a composite buffer and heat dissipation structure on the roller body and the base, which consists of reinforcing ribs, buffer layer, hollow holes, and conical holes working together. It achieves the technical effect of significantly improving the roller's impact resistance, structural stability, and heat dissipation efficiency, thereby extending its service life and ensuring processing accuracy.

[0021] 2. This utility model solves the problem in the prior art that diamond rollers, as precision tools, are damaged by collisions and drops during transportation and storage due to the lack of effective protective measures by adding a special packaging mechanism with a protective shell, locking components and internal fixing foam. It achieves the technical effect of providing all-round, multi-layer buffer protection for the rollers, ensuring their safety and integrity in non-working state, and facilitating safe storage and transportation.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figure 3 and Figure 4An impact-resistant diamond roller includes a main body 1 and a base 2 integrally formed with the main body 1. The main body 1 and the base 2 together constitute the body structure of the diamond roller. The main body 1 serves as a working component that carries diamond particles and performs dressing and grinding functions, while the base 2 serves as a connecting component for mounting and fixing the entire diamond roller on an external processing device. To improve the impact resistance and heat dissipation efficiency of the roller body during operation, a buffer mechanism 3 is integrally provided on the main body 1 and the base 2. The buffer mechanism 3 uses an internal composite structure design to synergistically enhance the structural strength of the roller body, absorb and disperse external impact forces, and simultaneously construct a flow path for the cooling medium to achieve efficient heat dissipation. In addition, this utility model also provides a packaging mechanism 4, which detachably wraps and accommodates the roller body composed of the main body 1 and the base 2. The packaging mechanism 4 provides comprehensive physical protection for the roller body during transportation and storage in non-working states, preventing damage to the roller body from accidental impacts, vibrations, and drops.

[0031] Please refer to Figure 3 and Figure 4 The buffer mechanism 3 is integrally set on the main body 1 and the base 2. Specifically, the buffer mechanism 3 includes reinforcing ribs 31 integrally formed between the main body 1 and the base 2. The reinforcing ribs 31 are radially distributed with the center of the main body 1 as the center. This radial structural layout can effectively and evenly distribute the impact force from the outside to the entire roller body, thereby significantly enhancing the structural rigidity and deformation resistance of the main body 1. Each reinforcing rib 31 has a perforated hole 32. The design of the perforated hole 32, while ensuring the structural strength of the reinforcing rib 31, effectively reduces the overall weight of the roller body and avoids... The excessive weight causes imbalance during high-speed rotation. At the same time, the hollow holes 32 also form a channel for auxiliary heat dissipation. A conical hole 33 is also provided on the main body 1 near the reinforcing rib 31. The opening of the conical hole 33 has a special conical structure with the inner diameter gradually decreasing along the direction of coolant inflow. This structure can guide and accelerate the coolant flow into the interior of the main body 1, and provide forced and efficient flushing and cooling to the roller area. In order to directly absorb and disperse impact energy, a buffer layer 34 is also fixedly connected to the outer periphery of the main body 1. The buffer layer 34 is preferably made of a nickel-based alloy material with excellent toughness and energy absorption.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4The packaging mechanism 4 specifically includes a protective shell 41. The internal space of the protective shell 41 is adapted to the contour of the roller body composed of the main body 1 and the base 2, and can completely accommodate the roller body therein. A door panel 42 is provided on one side of the protective shell 41. The door panel 42 is rotatably connected to the protective shell 41 through a hinge structure, so as to facilitate opening and closing, thereby facilitating the loading and unloading of the roller body. To ensure that the door panel 42 will not be accidentally opened during transportation and handling, a clamp 43 and a latch 44 are also provided on the side of the door panel 42 away from the hinge. The clamp 43 and the latch 44 together form a double locking system, which can firmly lock the door panel 42 onto the protective shell 41, thereby... To prevent the roller body from slipping out of the protective shell 41 due to vibration and inversion, and further to prevent the roller body from shaking and colliding inside the protective shell 41, a fixing foam 45 is filled and fixed on the inner wall of the protective shell 41. The fixing foam 45 is a highly elastic cushioning material with a pre-formed shape that can tightly clamp the roller body placed inside it, playing a role in limiting and fixing. At the same time, the excellent cushioning performance of the fixing foam 45 itself can also absorb most of the impact energy when the protective shell 41 is subjected to external impact, such as when it is dropped, providing a second layer of cushioning protection for the roller body. The material of the fixing foam 45 is preferably polyether polyurethane.

[0033] Working principle: A buffer mechanism 3 is provided on the front side of the main body 1. The main body 1 is connected to the base 2. A packaging mechanism 4 is provided on the outside of the main body 1 and the base 2. The buffer mechanism 3 buffers the main body 1 and blocks the impact of the grinding wheel on the main body 1. The packaging mechanism 4 can facilitate the transportation and storage of the main body 1 and prevent the main body 1 from being discarded or placed at will.

[0034] A reinforcing rib 31 is provided between the main body 1 and the base 2. The reinforcing rib 31 is used to strengthen the structure of the main body 1, resist the deformation of the main body 1 and strengthen the overall thickness. The reinforcing rib 31 is distributed from the center to the periphery, which can better increase the strength of the main body 1. However, adding reinforcing rib 31 to the main body 1 and the base 2 will increase the weight of the main body 1 and cause the main body 1 to deviate from the target. Therefore, a hollow hole 32 is opened on the reinforcing rib 31. The design of the hollow hole 32 allows the reinforcing rib 31 to reduce its own weight while retaining its original function, and can also serve as a cooling channel for the main body 1. A tapered hole 33 is opened next to the reinforcing rib 31. The tapered hole 33 adopts a design with a wide inlet and a narrow outlet to guide the coolant to flow quickly into the interior of the main body 1 and flush it. With the main heat dissipation guidance of the tapered hole 33 and the assistance of the hollow hole 32, the main body 1 can dissipate heat more quickly. A buffer layer 34 is provided on the left and right sides of the main body 1. The buffer layer 34 is made of nickel-based alloy and can absorb and disperse the force when the main body 1 is subjected to the impact from the grinding wheel.

[0035] The protective shell 41 completely encloses the main body 1 for easy storage. A door panel 42 is provided on the front side of the protective shell 41. The main body 1 can be taken out by opening the door panel 42. A clamp 43 and a latch 44 are added to the door panel 42. The clamp 43 and the latch 44 can lock the door panel 42 to prevent the main body 1 from falling out due to the inversion of the protective shell 41. Because the interior of the protective shell 41 is very spacious, a fixing foam 45 is set inside the protective shell 41. The fixing foam 45 is made of polyether polyurethane. The main body 1 can be directly placed into the protective shell 41. Then the fixing foam 45 will clamp the main body 1 to prevent it from shifting inside the protective shell 41. The fixing foam 45 also has a cushioning effect. If the protective shell 41 falls to the ground, the fixing foam 45 will also protect the main body 1.
