Description

Technical Field

[0001] This utility model relates to the field of motor and oil pump connection technology, specifically a connection tooling for a mining mill oil station motor and oil pump. Background Technology

[0002] Mining mills are crucial equipment in industries such as mining and building materials for fine grinding of ores. Their operational stability directly impacts the output, energy consumption, and maintenance costs of the entire production system. To ensure the continuous and reliable operation of mining mills under harsh environments such as long-term operation, high load, high temperature, and high dust, an efficient and stable lubrication system is essential.

[0003] The oil station in a lubrication system acts as the "power source" and "blood supply center" of the entire system, its task being to provide a stable flow of lubricating oil to key components (such as main bearings, reducers, and motors). The oil pump is the core component of the oil station system, typically driven by a motor to directly output power and circulate the lubricating oil. The performance of the oil pump and the transmission stability with the motor are key factors affecting the efficiency and reliability of the oil station system.

[0004] Currently, a rigid direct-drive structure is widely used for mounting motors and oil pumps. This structure typically consists of an integrated coupling or a fixed-length connecting assembly. While this method is simple in structure and quick to install, it presents the following prominent problems in practical engineering applications:

[0005] Poor installation compatibility: Due to the fixed length of the direct-drive structure, if the actual installation position of the motor and oil pump is offset or a different model of equipment is replaced, the entire connecting fixture needs to be replaced; Difficult manual alignment: This structure relies on manual adjustment of coaxiality and axial spacing, which limits assembly accuracy and easily leads to coaxial deviation and uneven torque. After long-term operation, it is prone to bearing wear, increased noise, and even equipment failure; Moreover, the rigid connection cannot absorb the mechanical impact and vibration during motor startup or operation, which can easily cause mechanical impact damage and abnormal axial load transmission, especially in high-power mining mills.

[0006] Therefore, the current connection method between the motor and oil pump of the mining mill oil station has obvious technical limitations in terms of adaptability, precision, stability, and impact resistance. There is an urgent need for a new type of connection tooling that is structurally adjustable, has self-positioning capabilities, and possesses an elastic buffering mechanism to improve assembly accuracy, reduce error accumulation, and enhance the overall operational reliability of the oil station system. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the existing defects and provide a connection tooling for the motor and oil pump of a mining mill oil station. By introducing a plug-in positioning structure, a sliding adjustment structure and an elastic buffer component, the structural adjustability, installation convenience and operation stability of the connection method between the motor and oil pump of the mining mill oil station are systematically improved, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A connecting fixture for a mining mill oil station motor and an oil pump, comprising a connecting ring one, a fixed plate, an abutment ring, and a connecting ring two. A plug-in sleeve is provided circumferentially on the connecting ring two, and a pin is provided circumferentially on the fixed plate. The pin is inserted into the plug-in sleeve. The connecting ring two and the fixed plate are connected by plugging. The pin actively guides the pin into the plug-in sleeve and limits misalignment, avoiding manual alignment, preventing the connecting ring from shifting, and improving assembly repeatability and stability. One end of the plug-in sleeve is provided with an abutment ring, and a spring is provided on the pin. The other end of the spring abuts against the abutment ring. On the contact ring, the plug-in sleeve not only increases the structural strength of the plug-in sleeve, but also acts as an elastic support point and spring to make the connection elastic, ensuring the stability of the connection structure. The second connecting ring is connected to the output flange of the motor. The plug-in structure between the second connecting ring and the first connecting ring can adapt to different connection lengths, meet the installation requirements of the motor and the slag vertical mill oil pump at different positions, and improve the practicality of the tooling. The first connecting ring is located on the other side of the fixed plate. The fixed plate and the first connecting ring are connected by a connecting plate, and the diameter of the first connecting ring is smaller than the diameter of the fixed plate. The first connecting ring is used to connect to the flange of the slag vertical mill oil pump.

[0009] Installation method:

[0010] The motor flange is placed flat on the surface of the gas station housing. The motor output flange is parallel to the second connecting ring. The object is positioned by the tooling and the motor hole.

[0011] The motor output flange contacts the bottom surface of the connecting ring and is tightened with fastening bolts.

[0012] Connecting ring one and oil pump end flange are positioned by tooling and oil pump hole. Oil pump end flange contacts bottom surface of connecting ring one and is tightened by fastening bolts.

[0013] Working principle: The flange fixed to the output shaft of the motor is tightened with fastening bolts; then the tooling is used to position the object at the input shaft of the oil pump, and the fastening bolts are tightened to precisely fix the position of the oil pump and the motor, ensuring reliable and stable power transmission and further reducing the vibration transmission of the motor; at the same time, driven by the motor, the oil pump can circulate the lubricating oil more stably due to the presence of the connecting tooling, improving the operational stability of the oil station.

[0014] Furthermore, at least three plug-in sleeves are provided, and the plug-in sleeves are evenly distributed along the circumference of the second connecting ring.

[0015] Furthermore, an inner connecting component is provided between the fixed plate and the second connecting ring. The inner connecting component includes a central sleeve and a central shaft. One end of the central sleeve is fixed to the fixed plate. A guide groove is provided in the circumferential direction of the inner wall of the central sleeve, and a guide rail is provided in the circumferential direction of the central shaft. The central shaft is connected to the central sleeve through the cooperation of the guide groove and the guide rail. This inner connecting component is slidably connected through the cooperation of the guide groove and the guide rail to realize the power transmission of different lengths. With the external connection of the plug-in sleeve, the stable power output of the motor is ensured.

[0016] Furthermore, a support plate is provided at the other end of the central shaft, and the support plate is connected to the second connecting ring via a support arm.

[0017] Furthermore, the centers of connecting ring two, support plate, contact ring, fixing plate and connecting ring one are on the same straight line, and fixing holes are respectively provided in the circumferential direction of connecting ring two and connecting ring one.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model solves the problem of difficult manual alignment in traditional direct-connection by designing a quick-connection structure between the pin and the plug sleeve. This structure allows the pin to be accurately guided into the plug sleeve in a fixed direction, achieving automatic limit positioning and avoiding displacement of the connecting ring, thereby significantly improving the efficiency and consistency of the assembly process. Combined with the sliding guide structure between the central shaft and the central sleeve, an adjustable-length modular connection assembly is formed, which can adapt to the changes in axial installation position between different models of motors and oil pumps, significantly improving the versatility and installation flexibility of the tooling.

[0020] 2. A spring is provided on the pin, one end of which abuts against the contact ring at the end of the plug sleeve, forming an elastic pre-tightening device. This structure ensures the reliability of the plug positioning while giving the connection interface a certain axial buffering capacity, which can effectively absorb the micro-vibration and impact load generated during motor start-up or operation, avoid impact concentration and local stress fatigue caused by hard connection of shaft system, thereby improving the connection life of motor and oil pump and the overall operation stability of system.

[0021] 3. The positioning connection is formed by the plug sleeve and the pin. The internal sliding internal connection component is formed by the cooperation of the central shaft and the guide rail and guide groove of the central sleeve. The dual connection paths work together in the power transmission process. This double-layer structure not only improves the overall connection rigidity and anti-displacement ability, but also introduces springs and abutment rings inside to effectively absorb axial impact and vibration during operation.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a connecting fixture for a mining mill oil station motor and an oil pump, including a connecting ring 1 6, a fixing plate 7, a contact ring 8, a connecting ring 2 12, a plug sleeve 1, a pin 4, a spring 3, a connecting plate 5, a center sleeve 9, a center shaft 13, a support arm 10, a support plate 11, a guide groove 15, and a guide rail 2.

[0028] The connecting ring 12 has multiple plug sleeves 1 in the circumferential direction. Preferably, the plug sleeves 1 are evenly spaced along the circumferential direction, with at least three, to ensure multi-point guidance and force balance during the connection process. The fixed plate 7 has pins 4 in the circumferential direction corresponding to the plug sleeves 1. The pins 4 are inserted into the plug sleeves 1 to achieve plug-in positioning, avoid manual alignment, and limit the displacement of the connecting ring 12 during the assembly process.

[0029] The outer sleeve of the pin 4 is provided with a spring 3. One end of the spring 3 abuts against the abutting ring 8 provided at the end of the insertion sleeve 1, thereby providing elastic support and buffering function on the basis of insertion positioning, effectively absorbing assembly errors and working vibrations, and improving the reliability and smoothness of power transmission.

[0030] Connecting ring 2 12 is connected to the motor output flange by bolts; connecting ring 1 6 is connected to the oil pump input flange by bolts. Connecting ring 1 6 is located on the other side of the fixed plate 7 and is connected to the fixed plate 7 through the connecting plate 5 to form an integral support structure. The outer diameter of connecting ring 1 6 is smaller than that of the fixed plate 7, which facilitates nested connection.

[0031] To further achieve adjustable length and stable internal force transmission, an internal connecting assembly is provided between the fixed disk 7 and the connecting ring 12, including a central sleeve 9 and a central shaft 13. The central sleeve 9 is fixed on the fixed disk 7, and its inner wall is provided with a guide groove 15. The central shaft 13 is provided with a guide rail 2, which can be slidably embedded in the guide groove 15 to achieve axial length adjustment. This sliding fit structure ensures the assembly compatibility between different models of motors and oil pumps.

[0032] A support plate 11 is provided at the end of the central shaft 13 away from the insertion end. The support plate 11 is connected to the connecting ring 12 via the support arm 10 to enhance the rigidity and positioning capability of the internal connection assembly and prevent axial displacement during operation.

[0033] In the entire structure, the centers of connecting ring 1 6, fixing plate 7, contact ring 8, support plate 11 and connecting ring 2 12 are located on the same straight line to ensure the coaxiality of the power transmission path; both connecting ring 1 6 and connecting ring 2 12 are provided with fixing holes 14 in the circumferential direction for bolt fastening connection to ensure connection reliability.

[0034] The installation steps are as follows:

[0035] Place the motor output flange flat on the gas station housing mounting surface, keeping it parallel to the connecting ring 12.

[0036] Insert the pin 4 into the socket 1, and the spring 3 will guide, position and buffer the pin.

[0037] Secure the connecting ring 212 to the motor output flange using bolts;

[0038] Align the connecting ring 6 with the oil pump end flange, position it through the fixing hole 14, and tighten the bolts to complete the connection;

[0039] The plug-in structure and the inner sliding component work together to achieve a stable connection, precise positioning and length adaptation between the motor and the oil pump.

[0040] Technical effect description:

[0041] This embodiment achieves the adjustment function of the axial length of the motor and oil pump through the external quick-connect structure of the pin 4 and the plug sleeve 1, combined with the sliding connection of the guide groove 15 and the guide rail 2 between the center sleeve 9 and the center shaft 13, and has good adaptability and modularity; the elastic support structure formed between the pin 4 and the spring 3 enhances the assembly flexibility and absorbs the vibration and impact during operation.

[0042] Furthermore, the torsional resistance of the internal connection structure is further enhanced by the support arm 10 and the support plate 11, ensuring that power is transmitted along the coaxial path and significantly improving the operational stability and durability of the transmission system.

[0043] The entire set of connecting fixtures has a reasonable structure, strong versatility, and is easy to install. It is particularly suitable for rapid connection and stable power transmission between the motor and oil pump in the oil station of a mining mill, and has good prospects for industrial application.
