Description

Technical Field

[0001] This utility model relates to the technical field of silicon wafer cutting equipment, specifically to a tooling for loading and unloading the movable end of a bearing housing. Background Technology

[0002] In the crystal ingot processing and manufacturing process, the ingot bonding process is a crucial preliminary step. After the ingot bonding operation is completed, it must be immediately transferred to the crystal ingot cutting equipment for subsequent cutting operations to meet the precise requirements of subsequent production for the shape and size of the ingot. As the core processing equipment, the operational stability of the crystal ingot cutting equipment directly determines the cutting accuracy and production efficiency of the crystal ingot. As a key transmission component of this equipment, the bearing housing must continuously withstand the enormous radial and axial pressure generated by the crystal ingot cutting operation during long-term continuous operation of the equipment, and is in a high-load working state for a long time.

[0003] To ensure the reliable operation of crystal rod cutting equipment and avoid downtime or reduced cutting accuracy due to bearing housing failure, the industry generally requires regular disassembly and maintenance of the bearing housing. This involves disassembly and inspection, component cleaning, and replacement of worn parts to restore the bearing housing's performance. However, in actual disassembly and maintenance, operators face significant operational challenges: on the one hand, the bearing housing and equipment support structure employ a tight-fitting connection design to ensure connection stability, resulting in minimal gaps between them; on the other hand, the bearing housing's structural design lacks easily accessible gripping and force application points, making it difficult for operators to precisely adjust and secure the bearing housing during installation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of difficulty in accurately adjusting and fixing the bearing housing in the crystal rod cutting equipment during disassembly and assembly in the prior art, and to provide a bearing housing movable end loading and unloading fixture.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a bearing housing movable end loading and unloading fixture, which has an auxiliary block and a connecting joint. Two symmetrically distributed connecting protrusions are fixed on the auxiliary block. The auxiliary block can be inserted into the central hole of the bearing housing body, so that a gap is formed between the connecting protrusion and the inner wall of the connecting groove communicating with the central hole. The connector can be inserted into the gap, so that the connector presses against the connecting protrusion, thereby causing the auxiliary block to press against the inner wall of the center hole, so as to complete the interference fit between the connector and the bearing housing body. The connector is fixedly connected to a gripping component so that the operator can grip and rotate the bearing housing body.

[0006] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: a docking groove is provided at the center of the connecting protrusion, and the docking groove is inserted into the docking protrusion provided on the docking head.

[0007] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: the cross-section of the docking groove and the docking protrusion are both set as semi-circular.

[0008] As a further optimization of the bearing housing movable end loading and unloading tool of this utility model: the gripping member includes a connecting column that is fixedly connected to the butt joint.

[0009] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: the connecting column is provided with a threaded hole, the threaded hole is threadedly connected to a threaded rod, and the threaded rod is fixedly connected to a lever arm so as to adjust the length of the torque formed by the connecting column and the lever arm.

[0010] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: the outer periphery of the lever arm is fixedly provided with an anti-slip sleeve, the anti-slip sleeve being made of rubber.

[0011] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: the connecting protrusion, auxiliary block, butt joint and gripping parts are all made of engineering plastics.

[0012] As a further optimization of the bearing housing movable end loading and unloading fixture of this utility model: the connecting protrusion, auxiliary block, butt joint and gripping member are all provided with weight reduction grooves, and the weight reduction grooves are provided with reinforcing ribs.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes an auxiliary block and its connecting protrusion to engage with the central hole and connected groove of the bearing housing body. Simultaneously, a connector is inserted between the connecting groove and the connecting protrusion, enabling a detachable and stable connection between the connector-fixed grip and the bearing housing body. Subsequently, the angle of the bearing housing body is adjusted using the grip, allowing it to rotate within the connecting seat. This ensures that the first mounting hole on the bearing housing body and the second mounting hole on the connecting seat are concentric, facilitating angle adjustment and fixation by the operator. Finally, the first and second mounting holes are locked together using mounting screws, completing the installation of the bearing housing body and the connecting seat. Attached Figure Description

[0015] 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.

[0016] like Figure 1 As shown, a bearing housing movable end loading and unloading fixture includes an auxiliary block 4 that can be inserted into the center of the bearing housing body 7 and a mating connector 2 that mates with it. Two connecting protrusions 5 are symmetrically arranged on the auxiliary block 4. These two connecting protrusions 5 form a clearance fit with the connecting groove 13 on the bearing housing, thereby achieving precise alignment of the auxiliary block 4 with the center hole 14 of the bearing housing body 7. The auxiliary block 4 and connecting protrusions 5 are plugged into the mating protrusion 3 and mating connector 2. After the mating connector 2 is inserted into the gap between the mating protrusion 3 and the connecting groove 13, an interference fit is formed. The positive pressure generated by the deformation between the materials ensures that all three are stably clamped to the bearing housing body 7. The mating connector 2 is fixed to the gripping member 1. Through the rigid connection between the auxiliary block 4 and the mating connector 2, the torque force applied by the operator to the gripping member 1 is converted into the rotational force of the bearing housing, thereby achieving stepless adjustment of the angle of the bearing housing body 7 within the connecting seat 8. By leveraging the lever principle, the gripper 1 allows the operator to adjust the angle of the bearing housing body 7 with minimal effort, making the second mounting hole 11 on the connecting seat 8 concentric with the first mounting hole 10 on the bearing housing body 7. Finally, the axial preload of the mounting screw 12 achieves a stable connection between the connecting seat 8 and the bearing housing body 7, thereby assembling the bearing housing body 7 onto the support 9.

[0017] like Figure 2As shown, both connecting protrusions 5 are symmetrically provided with mating grooves 6, and the mating joint 2 is fixedly provided with a mating protrusion 3 that engages with the mating grooves 6, forming a double positioning structure. The addition of the mating grooves 6 and the mating protrusions 3 increases the contact area and the number of friction pairs between the mating joint 2 and the connecting protrusions 5, improves the connection rigidity, and effectively reduces the risk of the auxiliary block 4 and the mating joint 2 slipping off from the bearing housing when the holding part 1 drives the bearing housing to rotate in the connecting seat 8. This helps the operator to accurately adjust the angle of the bearing housing body 7 and ensures that the concentricity error of the first assembly hole 10 and the second assembly hole 11 is controlled within a reasonable range.

[0018] The gripper 1 includes a connecting post 105 fixedly connected to the connector 2. The connecting post 105 acts as a rotating arm, extending the torque required for the operator to rotate the bearing housing body 7 based on the lever principle, thus reducing the operating force. The connecting post 105 has a fine-pitch threaded hole 104, forming a helical transmission pair with the threaded rod 103. The distance between the opposing ends of the lever arm 102 and the connecting post 105 is infinitely adjustable through the thread helix angle. According to the formula for moment of inertia, extending the lever arm during initial rotation reduces the starting torque, allowing the first mounting hole 10 and the second mounting hole 11 to quickly become tangent. Figure 3 and Figure 4 As shown, after tangency, the lever arm is shortened, and high-precision fine adjustment is achieved based on the principle of angle error, ensuring that the first assembly hole 10 and the second assembly hole 11 quickly become concentric.

[0019] The lever arm 102 has an anti-slip sleeve 101 on its outer periphery away from the connecting column 105. The sleeve is made of elastic rubber and has a biomimetic anti-slip structure formed by evenly distributed grooves on its surface. According to the law of friction, the coefficient of friction between rubber and human skin is higher than that of steel. Combined with the sweat-wicking function of the grooves, it can improve grip friction and effectively prevent slippage caused by sweaty palms of the operator.

[0020] In practical use, such as Figure 3 and Figure 4 As shown, firstly, the bearing housing is installed into the connecting seat 8 and connected to the corresponding roller; then, the auxiliary block 4 is placed into the center hole 14, and the mating joint 2 is inserted between the connecting protrusion 5 and the connecting groove 13, so that the mating groove 6 and the mating protrusion 3 on the mating joint 2 form an interference fit. Through the clamping force generated by elastic deformation, a stable connection is achieved between the bearing housing body 7, the auxiliary block 4, and the mating joint 2. After the bearing housing body 7, the auxiliary block 4, and the mating joint 2 are stably connected, according to the lever principle, the power arm 102 is rotated by the anti-slip sleeve 101 on the grip 1, so that the threaded rod 103 is screwed out of the threaded hole 104, increasing the lever arm length. At this time, the rotation torque is reduced, which makes it easier to adjust the bearing housing angle so that the first mounting hole 10 and the second mounting hole 11 are tangent.

[0021] After the first mounting hole 10 and the second mounting hole 11 are tangent, the lever arm 102 can be rotated in the opposite direction to screw the threaded rod 103 into the threaded hole 104, reducing the lever arm length. At this time, the rotational torque increases, making it easier for the operator to fine-tune the rotation angle of the bearing housing body 7 to achieve concentricity of the first mounting hole 10 and the second mounting hole 11. Finally, the mounting screws 12 are inserted into the first mounting hole 10 and the second mounting hole 11 to complete the installation of the bearing housing body 7.

[0022] The connecting protrusion 5, auxiliary block 4, connector 2, and gripper 1 are all made of engineering plastic, and each component has weight-reducing grooves with reinforcing ribs inside. The reinforcing ribs maintain the structural strength of the connecting protrusion 5, auxiliary block 4, connector 2, and gripper 1, while also facilitating adjustments to the angle of the bearing housing body 7 for installation. Simultaneously, the number and shape of the weight-reducing grooves reduce the weight of the gripper 1, making it easier for operators to handle and move it, thus facilitating the disassembly and assembly of the bearing housing body 7 for different equipment.

[0023] The specific design of the weight-reducing groove, the specific parameters and models of the engineering plastics, and the setting of the reinforcing ribs should all be understood as existing technology. At the same time, the specific model, structure, and position of the first mounting hole 10, the second mounting hole 11, and the mounting screw 12, as well as the mating method between the bearing housing body 7 and the connecting seat 8, should also be understood as existing technology.

[0024] The specific embodiments of this utility model have been described above. 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 variations within the scope of the claims, which do not affect the substantive content of this utility model.
