Description

Technical Field

[0001] This utility model relates to the field of oil pump mounting bracket technology, and specifically to an oil pump mounting bracket structure that facilitates alignment. Background Technology

[0002] Currently, the hydraulic control system of the equipment is based on an electric motor, using an oil pump to convert mechanical energy into pressure to drive hydraulic oil. Typically, an oil pump mounting bracket is needed to fix the oil pump to the motor. As a crucial component of the hydraulic system, the alignment of the hydraulic pump with the motor shaft directly affects the overall system's operating efficiency and stability. However, the motor shaft center position can shift due to factors such as thermal expansion of the machine base and bearings, and motor rotation. Therefore, on-site installation by the user requires alignment based on the actual shaft center.

[0003] The most common oil pump mounting brackets on the market are often integrated, with the motor mounting surface and the oil pump mounting surface fixed. The oil pump is directly mounted on the oil pump mounting bracket. This structure is difficult to adjust and align, which will affect the operating efficiency and stability of the entire hydraulic system, and may even damage the equipment. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An oil pump mounting bracket structure for easy alignment includes a motor end cover and an oil pump. A motor output end is located in the middle of the motor end cover. A pad is provided on the motor end cover, and an alignment platform is mounted on the pad. The oil pump is mounted on the alignment platform. The pump shaft of the oil pump is fixedly connected to the motor output end by a coupling. Multiple equally spaced fixing holes are opened on the outer side of the alignment platform. Adjustment holes are opened on the pad corresponding to the fixing holes. The diameter of the adjustment holes is several times larger than the diameter of the fixing holes. Fixing bolts pass through the fixing holes and adjustment holes.

[0006] Furthermore, a fixing ring plate is fixedly installed on the motor end cover, and a pad is located directly above the fixing ring plate. The pad and the fixing ring plate are fixedly connected by multiple support frames. The support frames create a certain distance between the pad and the motor end cover to facilitate alignment and inspection of the motor output end and the pump shaft of the oil pump.

[0007] Furthermore, a large washer is installed on the fixing bolt at the position corresponding to the adjustment hole at the bottom of the pad. The radius of the large washer is larger than the diameter of the adjustment hole. At least two locating pins are also provided at the position between the middle platform and the pad, offset from the fixing bolt. Because the diameter of the adjustment hole is relatively large, the nut on the bolt may not be securely fixed when the fixing bolt is tightly against one side of the inner wall. Therefore, the large washer is provided to ensure the reliability of the fixation.

[0008] Furthermore, a protective cover is installed on the outside of the support frame between the motor end cover and the centering platform, and multiple ventilation pipes at equal intervals are fixedly installed on the protective cover. This protects the connection space between the motor and the oil pump, while also using the ventilation pipes to connect the inside and outside air for heat dissipation.

[0009] Furthermore, the protective cover has a conical cross-section, and each ventilation duct on the protective cover is fitted with a filter element via a fixing clip. The conical structure fits the relative position of the motor end cover and the pad, and the filter element is used to block dust and other foreign objects from entering the air.

[0010] Furthermore, the ventilation duct is inclined in a counter-clockwise direction. This inclination provides a guiding angle for the incoming and outgoing airflow, allowing it to easily circulate within the protective cover, thereby promoting airflow throughout the entire cover and ensuring effective ventilation and heat dissipation. The counter-clockwise inclination is just one option; a clockwise inclination also achieves the same effect.

[0011] Furthermore, the centering platform has a pre-set annular groove on its outer periphery, and an annular bar is set inside the annular groove. The annular bar rotates around the annular groove for a limited position. A threaded sleeve is fixedly installed on the outer side of the annular bar, and a threaded rod with a threaded connection passes through the threaded sleeve. Two limiting rods and two limiting rods are respectively set at both ends of the threaded rod, and the threaded rod is located between the two limiting rods. Rotating the threaded rod achieves a pushing effect on the centering platform. During centering adjustment, there is no need to push or tap the centering platform by hand, which facilitates operation.

[0012] Furthermore, the top of the pad has multiple equally spaced limiting holes corresponding to the positions of limiting rod one and limiting rod two. Limiting rod one and limiting rod two are inserted into the corresponding limiting holes to form a fixed connection. A connecting rod is fixedly connected between the tops of limiting rod one and limiting rod two. The limiting rods restrict the movement of the threaded rod, allowing it to rotate only around its own axis, thereby ensuring the pushing effect on the platform.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model is designed to install a central platform oil pump, and the central platform can be adjusted in any direction within the diameter range of the adjustment hole, thereby aligning the shaft of the oil pump with the shaft of the motor output end, achieving the desired alignment effect.

[0015] 2. In this utility model, a protective cover is provided at the connection position between the motor output end and the oil pump for protection, and a ventilation pipe is provided to allow airflow inside and outside the protective cover, so as to achieve the effect of dissipating internal heat to the outside.

[0016] 3. In this utility model, the ventilation pipe is placed at an angle, and the airflow enters and exits the protective cover at a certain angle. Combined with the initial flow velocity of the airflow, the overall air inside the protective cover can flow, thereby ensuring the exchange of overall air inside the protective cover with the outside, and ensuring the overall heat dissipation effect.

[0017] 4. In this utility model, a threaded sleeve and a threaded rod are provided, and the threaded rod is restricted by a limiting rod. At the same time, the threaded sleeve rotates around the centering platform through an annular strip. When adjusting the centering platform, the threaded sleeve can be freely rotated to a position parallel to the adjustment direction, and then the threaded rod can be rotated to move and adjust the entire centering platform.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides an oil pump mounting bracket structure that facilitates alignment, mainly solving the problem that the current integrated structure of oil pump mounting brackets is difficult to adjust for alignment. The following technical solution is provided, which will be discussed in conjunction with... Figure 1 - Figure 7 Please provide a detailed explanation:

[0028] An oil pump mounting bracket structure for easy alignment includes a motor end cover 1, a motor output end 23 located in the middle of the motor end cover 1, a fixing ring plate 2 fixedly mounted on the motor end cover 1, a pad 3 located directly above the fixing ring plate 2, the pad 3 and the fixing ring plate 2 being fixedly connected by multiple support frames 4, an alignment platform 5 located on the pad 3, an oil pump 24 fixedly mounted on the alignment platform 5, the pump shaft of the oil pump 24 being close to the motor output end 23, and the pump shaft of the oil pump 24 being fixedly connected to the motor output end 23 by a coupling 25;

[0029] Multiple equally spaced fixing holes 6 are provided on the outer side of the middle platform 5. An adjustment hole 7 is provided on the pad 3 corresponding to each fixing hole 6. The diameter of the adjustment hole 7 is several times larger than the diameter of the fixing hole 6, and the multiple is not less than three times. Fixing bolts 8 pass through the fixing holes 6 and the adjustment holes 7. A large washer 9 is installed on the fixing bolt 8 corresponding to the adjustment hole 7 at the bottom of the pad 3. The radius of the large washer 9 is larger than the diameter of the adjustment hole 7. At least two positioning pins 17 are also provided between the middle platform 5 and the pad 3 at positions offset from the fixing bolts 8.

[0030] First, adjust the centering platform 5. Use the positioning pin 17 to position the centering platform 5 and the pad 3. Then, install the fixing bolts 8 according to the diagram. Pass the fixing bolts 8 through the fixing hole 6 and the adjusting hole 7 to fix the centering platform 5 and the pad 3. Tighten the fixing bolts 8 to a semi-tight state. At this time, install the oil pump 24 on the centering platform 5. Then, remove the positioning pin 17. Based on the initial alignment of the oil pump 24 and the motor output end 23, use the semi-tight state of the fixing bolts 8 and the adjusting hole 7 with a diameter larger than the fixing bolts 8 to move the centering platform 5 and the oil pump 24 to adjust them to the center. After alignment, tighten each fixing bolt 8 that is in the semi-tight state. Then, use the coupling 25 to fix the pump shaft of the motor output end 23 and the oil pump 24 to complete the installation.

[0031] In some embodiments, a protective cover 19 is installed on the outside of the support frame 4 between the motor end cover 1 and the centering platform 5. The protective cover 19 has a cone-shaped cross-section and multiple ventilation pipes 20 with equal spacing are fixedly installed on the protective cover 19. Each ventilation pipe 20 has a filter 21 installed inside it through a fixing buckle 22.

[0032] The protective cover 19 isolates and protects the space between the motor end cover 1 and the centering platform 5, reducing the impact of the external environment on the connection position of the motor output end 23 and the oil pump 24. The ventilation pipe 20 is used for ventilation so that the internal heat can be dissipated to the outside for heat dissipation, avoiding the situation where the internal heat is continuously raised due to the heat transfer from the motor and the oil pump 24, which may ultimately affect the normal operation of the motor or the oil pump 24.

[0033] In some embodiments, the ventilation duct 20 is inclined in a counterclockwise direction.

[0034] The tilt direction can also be changed to a clockwise direction. Regardless of the direction, the effect is the same. Both are used to guide the air in and out of the protective cover 19, so that the air in and out is at a certain angle. Then, the air is rotated by sticking to the protective cover 19. The rotation of the air drives the air inside the protective cover 19, thereby reducing areas with poor air circulation and ensuring the circulation and heat dissipation of the air inside the protective cover 19.

[0035] In some embodiments, an annular groove 11 is pre-set on the outer periphery of the platform 5, and an annular bar 10 is provided in the annular groove 11. The annular bar 10 is limited to rotate around the annular groove 11. A threaded sleeve 12 is fixedly installed on the outer side of the annular bar 10. A threaded rod 13 with threaded connection is passed through the threaded sleeve 12. Two limit rods 14 and two limit rods 15 are respectively provided at both ends of the threaded rod 13. The threaded rod 13 is located between the two limit rods 14 and the two limit rods 15. A plurality of limit holes 18 with equal spacing are opened on the top of the pad 3 corresponding to the positions of the limit rods 14 and the limit rods 15. The limit rods 14 and 15 are inserted into the limit holes 18 at the corresponding positions to form a fixed insertion. A connecting rod 16 is fixedly connected between the top of the limit rods 14 and the limit rods 15.

[0036] When the fixing bolt 8 is half-tightened and the centering platform 5 is being adjusted, the annular bar 10 can be rotated first according to the adjustment direction to make the threaded sleeve 12 parallel to the adjustment direction. Then, the limiting rod 14 and the limiting rod 25 are inserted into the limiting holes 18 at both ends of the threaded sleeve 12, and the threaded rod 13 is screwed into the threaded sleeve 12. The threaded rod 13 is continuously rotated. Because the threaded rod 13 is blocked by the two limiting rods 14 and the two limiting rods 25, it cannot drive the annular bar 10 to rotate along the annular groove 11, and is thus limited to... It can move along the axial direction of the threaded sleeve 12, and the threaded sleeve 12 is parallel to the adjustment direction. Therefore, rotating the threaded rod 13 will force the centering platform 5 to move, thereby achieving the effect of moving and adjusting the centering platform 5, which facilitates the adjustment operation. As shown in the attached figure, the limiting rod 14 restricts the forward rotation of the threaded rod 13, but does not restrict the backward rotation. Therefore, only forward rotation can achieve the pushing effect on the centering platform 5. When pushing in the opposite direction, rotate the annular bar 10 to bring the threaded sleeve 12 to the opposite direction.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
