Description

Technical Field

[0001] This utility model relates to the field of silicon wafer cutting technology, specifically to a bearing housing mounting and protection component for silicon wafer cutting equipment. Background Technology

[0002] With the rapid development of the semiconductor and photovoltaic industries, large-size silicon wafers are gradually becoming the mainstream development direction in the industry due to their higher production efficiency and lower manufacturing costs. As a key component of wire EDM equipment, the assembly quality of the spindle system plays a decisive role in the overall performance of the equipment. Among these, the precise installation of the bearing housing and the load-bearing housing is a crucial step in ensuring the stable operation of the spindle system.

[0003] In existing technologies, when installing the bearing housing into the holes of the carrier housing, it is usually necessary to use external force to hammer it to achieve a tight fit. However, directly hammering the bearing housing with a rigid tool inevitably causes damage such as dents and cracks on the surface of the bearing housing, which in turn affects the sealing performance and mechanical strength of the bearing housing, shortens its service life, and may even cause vibration and abnormal noise during spindle operation, seriously affecting the cutting quality of silicon wafers. To solve the problem of hammering damage, some technologies have attempted to use elastic hammers for installation. However, because the buffering effect of the elastic hammer weakens the impact force effectively transmitted to the bearing housing, the bearing housing is unable to overcome the assembly resistance between the holes and cannot be installed smoothly, resulting in a significant reduction in installation efficiency and failing to meet the needs of large-scale industrial production. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the difficulty in effectively and safely installing bearing housings in the prior art, and to provide a bearing housing installation and protection component for silicon wafer cutting equipment.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a bearing housing mounting and protection component for a silicon wafer cutting equipment, which has a threaded rod capable of connecting to a threaded hole opened on the bearing housing, and a protective cover is fitted on the threaded rod.

[0006] The protective cover can be installed on the end face of the bearing housing to distribute the impact force from the closed end face of the protective cover to the bearing housing, so that the bearing housing is evenly displaced within the hole of the bearing housing.

[0007] As a further optimization of the bearing housing installation and protection component for silicon wafer cutting equipment of this utility model: a grip is fixedly provided at the end of the threaded rod, and the threaded rod and the grip are arranged in a T-shape.

[0008] As a further optimization of the bearing housing installation and protection component for silicon wafer cutting equipment of this utility model: the surface of the grip handle is provided with an elastic anti-slip layer.

[0009] As a further optimization of the bearing housing mounting protection component for silicon wafer cutting equipment of this utility model: the end of the protective cover facing the bearing housing is provided with a thickened part to increase the contact area between the protective cover and the bearing housing.

[0010] As a further optimization of the bearing housing mounting protection component for silicon wafer cutting equipment of this utility model: the thickened part is a ring provided at the open end, and the thickness of the ring is greater than the thickness of the protective cover.

[0011] As a further optimization of the bearing housing installation protection component for silicon wafer cutting equipment of this utility model: the threaded rod is provided with a limiting plate that can restrict the protective cover. The limiting plate can make a certain distance between the end of the threaded rod and the protective cover, so as to facilitate the gripping of the threaded rod.

[0012] As a further optimization of the bearing housing installation protection component for silicon wafer cutting equipment of this utility model: an elastic ring is provided at the center of the protective cover, and a deformation groove is provided on the elastic ring, so that the protective cover can be easily disassembled from the threaded rod.

[0013] As a further optimization of the bearing housing installation protection component for silicon wafer cutting equipment of this utility model: the protective cover is made of aluminum alloy.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses a threaded rod to align the protective cover with the bearing housing axis, allowing the thickened portion of the protective cover to be aligned with the bearing housing. During bearing housing installation, workers can tap the protective cover to evenly distribute and transfer the concentrated force to the bearing housing, thus stably driving its displacement and smoothly positioning it into the mounting holes until installation is complete. The protective cover and threaded rod not only effectively assist workers in quickly installing the bearing housing but also significantly reduce damage to the bearing housing's end face and internal structure caused by tapping.

[0020] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0021] like Figure 1 and Figure 2 As shown, a bearing housing mounting protective assembly for a silicon wafer cutting equipment includes a threaded rod 6 that matches the threaded hole 2 at the end of the bearing housing 3. A protective cover 5 is fitted onto the threaded rod 6, and the protective cover 5 corresponds to the end face of the bearing housing 3 furthest from the bearing housing 3. In actual operation, the threaded hole 2 and the main bearing roller are coaxially arranged. When the threaded rod 6 is tightly connected to the threaded hole 2, the protective cover 5 and the bearing housing 3 can maintain a relatively concentric state. The relative concentricity between the protective cover 5 and the bearing housing 3 not only ensures the accuracy of installation but also lays a solid foundation for subsequent operations. Next, the operator will use a professional tool to tap the end face of the protective cover 5, avoiding the threaded rod 6, so that it accurately impacts the bearing housing 3 roughly along its axis. In this process, the protective cover 5 plays a crucial role, converting the unidirectional impact force into a more uniform and larger-area impact force, thereby ensuring that the bearing housing 3 is stably installed into the hole of the bearing housing 1 without damage. This ingenious transformation not only improves installation accuracy but also avoids equipment damage that may be caused by improper operation, thereby extending the equipment's service life and reducing the company's operating costs. After the bearing housing 3 is impacted into place, the bearing housing 3 can be rotated via the threaded rod 6 to align the countersunk hole on the bearing housing 3 with the fixing screw hole on the carrier housing 1. Then, the operator can use bolts to stably fix the bearing housing 3 to the carrier housing 1, thus completing the installation and fixing of the bearing housing 3.

[0022] A handle 4 is fixedly connected to one end of the threaded rod 6, forming a T-shape, which facilitates easy handling by the operator and ensures a tight connection between the threaded rod 6 and the threaded hole 2. The threaded rod 6 can be threaded into the threaded hole 2 at the end of the bearing housing 3, thereby assisting the operator in accurately aligning the bearing housing 3 with the hole position on the carrier housing 1. After the bearing housing 3 is aligned with the hole position on the carrier housing 1, the operator can push the protective cover 5 on the threaded rod 6 to press against the carrier housing 1, and then tap the protective cover 5 to impact the bearing housing 3, causing the bearing housing 3 to be installed into the hole position on the carrier housing 1. The surface of the handle 4 is provided with an elastic protective layer to facilitate the operator's grip and movement of the bearing housing 3. Specifically, the elastic anti-slip layer is composed of elastic rubber with raised protrusions on the surface.

[0023] The protective cover 5 is fitted onto the optical axis section of the threaded rod 6, with a thickened portion 8 at the end facing the bearing housing 3. The thickened portion 8 is trumpet-shaped, meaning it has a ring at the open end of the protective cover 5, and its wall thickness is greater than that of the protective cover 5. The thickened portion 8 not only increases the contact area but also stably guides and disperses the impact force onto the bearing housing 3, thus aiding in stable installation. In actual operation, when the protective cover 5 is struck as an impact surface, it can effectively absorb and disperse the impact force, protecting the bearing housing 3 from damage. This improves the safety during the installation of the bearing housing 3 and ensures the long-term stable operation of the equipment. Figure 3 As shown, a limiting disc 7 is fixedly installed on the optical axis section of the threaded rod 6. The limiting disc 7 maintains a certain distance between the grip 4 and the protective cover 5. This design makes it easier for workers to hold the grip 4 to move the bearing housing 3, thereby improving work efficiency. Meanwhile, an elastic ring 9 is provided at the center of the protective cover 5. This elastic ring 9 can flexibly separate from or connect with the optical axis section of the threaded rod 6, allowing workers to easily replace the protective cover 5 according to actual needs. It also facilitates the sliding of the protective cover 5 on the optical axis section of the threaded rod 6, making it easier for workers to insert bolts into the countersunk holes on the end face of the bearing housing 3. The elastic ring 9 not only facilitates daily maintenance and replacement work but also ensures the reliability and durability of the protective cover 5 during long-term use. The protective cover 5 is made of aluminum alloy to ensure the efficiency of impact force transmission, and its flexible material properties provide protection for the bearing housing 3.

It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or alterations within the scope of the claims without affecting its substance.
