Description

Technical Field

[0001] This utility model relates to the field of parts drilling technology, specifically a clamping fixture for an oil injection ring in a wind turbine gearbox. Background Technology

[0002] The oil injection ring of a wind turbine gearbox is a ring-shaped oil injection device installed inside the gearbox. It sprays lubricating oil onto the surfaces of high-speed meshing gears, bearings, and friction pairs through evenly distributed nozzles, forming an oil film to reduce friction and wear, while also carrying away frictional heat to prevent local overheating and tooth surface scuffing. The oil injection ring consists of a three-way connector and two arc-shaped spray rods. The arc-shaped spray rods are evenly distributed with spray holes. During the processing of the oil injection ring, it is necessary to perform electric spark drilling on the arc-shaped spray rods to form the spray holes.

[0003] According to a public notice (No.: CN219004853U) of an EDM drilling and clamping fixture for an oil injection ring, the above application includes a base with a positioning plane on one side; a first positioning component, which is fixed to the top surface of the base by a mounting component, for positioning and fixing the arc-shaped spray bar of the oil injection ring; and a second positioning component, which is fixedly set on the top surface of the first positioning component, for positioning the tee of the oil injection ring.

[0004] However, in actual use, the above-mentioned clamping fixture requires multiple sets of pressure plates to be installed with bolts to position and fix the spray bar. Each assembly and disassembly requires tightening and loosening multiple bolts one by one, which takes a long time and affects the batch processing cycle. It is also difficult to ensure that the clamping force of each pressure plate is consistent with multiple bolts, resulting in local clamping that is too tight or too loose, causing deformation or slippage. In view of this, we propose a clamping fixture for the oil injection ring of a wind turbine gearbox. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture for the oil injection ring of a wind turbine gearbox, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for an oil injection ring in a wind turbine gearbox, comprising an operating table, wherein a clamping assembly is provided on the top end face of the operating table, and the clamping assembly includes:

[0007] A servo motor, wherein a stud is fixedly connected to the output end of the servo motor, and a positioning ring is provided on the side wall of the stud;

[0008] A hexagonal prism, wherein an adjustment module is provided on the side wall of the hexagonal prism, the adjustment module includes an installation sleeve that fits onto the side wall of the hexagonal prism, a hinge rod one is hinged to the side wall of the installation sleeve, and a hinge rod two is hinged to the end face of the hinge rod one.

[0009] The lower support frame is hinged to the second hinge rod, and the second hinge rod is hinged to the upper limit frame;

[0010] A vertical rod is provided, with a horizontal frame fixedly connected to its top end, and an adjusting bolt threadedly connected to the top end of the horizontal frame.

[0011] Preferably, the servo motor is fixedly connected to the bottom end face of the operating table, and two sets of positioning rings and adjustment modules are provided. The positioning ring on the lower side is sleeved with a stud, and the positioning ring on the upper side is threadedly connected to the stud.

[0012] Preferably, the second hinge rod in the adjustment module on the lower side is hinged to the lower support frame, and the second hinge rod in the adjustment module on the upper side is hinged to the upper limit frame.

[0013] Preferably, the hexagonal prism is rotatably connected to the top end face of the operating table, and the second hinge rod is inserted into the positioning ring, with the positioning ring limiting the position of the second hinge rod.

[0014] Preferably, the vertical rod is fixedly connected to the top end face of the operating table, and the vertical rod is sleeved with the positioning ring. The vertical rod limits the positioning ring so that the positioning ring can only move longitudinally.

[0015] Preferably, a hexagonal connecting post is fixedly connected to the bottom end of the adjusting bolt. The connecting post is inserted into the hexagonal prism, and rotating the adjusting bolt causes the hexagonal prism to rotate.

[0016] Preferably, the inner wall of the lower support bracket is rotatably connected to a bidirectional screw, the inner wall of the lower support bracket is fixedly connected to a crossbar, the side wall of the bidirectional screw is threadedly connected to a clamping plate, and the clamping plate is slidably connected to the crossbar.

[0017] Compared with the prior art, this utility model provides a clamping fixture for the oil injection ring of a wind turbine gearbox, which has the following advantages:

[0018] 1. This wind turbine gearbox oil injection ring clamping fixture, through its designed clamping components, allows for the simultaneous opening or closing of the upper and lower clamping frames by simply rotating an adjusting bolt. This eliminates the need for multiple pressure plates at multiple points, making the clamping and disassembly of the oil injection ring faster and reducing manual adjustment errors. The number of rotations of the adjusting bolt directly determines the opening or closing range of the upper and lower support frames and the upper limit frame, thus adapting to oil injection rings of different diameters and thicknesses. Regardless of the size of the oil injection ring, the lower support frame will ultimately push the oil injection ring onto the positioning ring, avoiding the need to change multiple sets of fixtures. The upper limit frame presses down on the oil injection ring, preventing it from suddenly slipping or shifting due to improper force applied by the operator. The oil injection ring remains stable during clamping, preventing positioning deviations caused by slippage, ensuring accurate EDM drilling positions, and improving the consistency of the finished product.

[0019] 2. The oil injection ring clamping fixture of this wind turbine gearbox limits the three-way part of the oil injection ring through the set clamping plate, preventing the oil injection ring from shifting in the circumferential direction, so that the oil injection ring is reliably fixed in the circumferential direction and ensuring that the hole position and the reference position are accurate.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a wind turbine gearbox oil injection ring clamping fixture, including an operating table 1, and a clamping assembly 2 is provided on the top end face of the operating table 1. The clamping assembly 2 includes a servo motor 201, a stud 202, a positioning ring 203, a hexagonal prism 204, an adjustment module 205, a lower support bracket 206, an upper limit bracket 207, a vertical rod 208, a horizontal frame 209, and an adjusting bolt 210.

[0026] In one embodiment of this utility model, a servo motor 201 is fixedly connected to the bottom end face of the operating table 1. A stud 202 is fixedly connected to the output end of the servo motor 201. A positioning ring 203 is provided on the side wall of the stud 202. There are two sets of positioning rings 203 and adjustment modules 205. The positioning ring 203 on the lower side is sleeved with the stud 202, and the positioning ring 203 on the upper side is threadedly connected to the stud 202.

[0027] The hexagonal prism 204 is rotatably connected to the top end face of the operating table 1. An adjustment module 205 is provided on the side wall of the hexagonal prism 204. The adjustment module 205 includes a mounting sleeve 2051 that is sleeved on the side wall of the hexagonal prism 204. A hinge rod 2052 is hinged to the side wall of the mounting sleeve 2051. A hinge rod 2053 is hinged to the end face of the hinge rod 2052. The hinge rod 2053 in the lower adjustment module 205 is hinged to the lower support frame 206. The hinge rod 2053 in the upper adjustment module 205 is hinged to the upper limit frame 207. The hinge rod 2053 is inserted into the positioning ring 203. The positioning ring 203 limits the hinge rod 2053.

[0028] The vertical rod 208 is fixedly connected to the top end face of the operating table 1. The vertical rod 208 is sleeved with the positioning ring 203. The vertical rod 208 limits the positioning ring 203 so that the positioning ring 203 can only move longitudinally. The top of the vertical rod 208 is fixedly connected to the horizontal frame 209. The top of the horizontal frame 209 is threadedly connected to the adjusting bolt 210. The bottom of the adjusting bolt 210 is fixedly connected to the hexagonal connecting post. The connecting post is inserted into the hexagonal prism 204. Rotating the adjusting bolt 210 drives the hexagonal prism 204 to rotate.

[0029] Rotating the adjusting bolt 210 in the reverse direction causes the mounting sleeve 2051 to rotate, thereby pulling the first hinge rod 2052 and the second hinge rod 2053, causing the lower support bracket 206 and the upper limit bracket 207 to retract, placing the oil injection ring between the lower support bracket 206 and the upper limit bracket 207. Rotating the adjusting bolt 210 in the forward direction causes the hexagonal prism 204 and the mounting sleeve 2051 to rotate, pushing the first hinge rod 2052 and the second hinge rod 2053, thereby causing the lower support bracket 206 and the upper limit bracket 207 to move away from the positioning ring 203. Supported by the lower support bracket 206, the upper and lower clamping frames can be opened or closed simultaneously by simply turning one adjusting bolt 210. This eliminates the need for tightening multiple pressure plates at multiple points, making it faster to clamp and remove the oil injection ring and reducing manual adjustment errors. The number of turns of the adjusting bolt 210 directly determines the opening or closing range of the upper and lower support brackets 206 and the upper limit bracket 207. Therefore, it can accommodate oil injection rings of different diameters and thicknesses. Regardless of the size of the oil injection ring, the lower support bracket 206 will eventually push the oil injection ring onto the positioning ring 203, avoiding the need to change multiple sets of tooling.

[0030] When the threads of the adjusting bolt 210 are engaged, there is friction between the thread surfaces. When the thread helix angle is less than the friction angle of the thread pair, the bolt cannot automatically loosen under axial load and exhibits self-locking properties. The self-locking structure can prevent reverse loosening and ensure that the injection ring is always reliably clamped.

[0031] Servo motor 201 drives stud 202 to rotate, causing positioning ring 203 on the side of upper limit bracket 207 to descend, further driving adjustment module 205 and upper limit bracket 207 to descend, so that upper limit bracket 207 presses down on oil injection ring, preventing oil injection ring from suddenly slipping or shifting due to improper force applied by the operator. Oil injection ring remains stable during clamping process and will not cause positioning deviation due to slippage, ensuring accurate EDM drilling position and improving product consistency.

[0032] In addition, a bidirectional screw 3 is rotatably connected to the inner wall of the lower support bracket 206, and a crossbar 5 is fixedly connected to the inner wall of the lower support bracket 206. A clamping plate 4 is threadedly connected to the side wall of the bidirectional screw 3. The clamping plate 4 is slidably connected to the crossbar 5. Rotating the bidirectional screw 3 causes the clamping plates 4 to move towards each other. The clamping plates 4 limit the T-joint of the oil injection ring to prevent the oil injection ring from shifting in the circumferential direction. If the oil injection ring rotates circumferentially during EDM drilling, it will cause the hole position to shift. The clamping plates 4 limit the T-joint to reliably fix the oil injection ring in the circumferential direction, ensuring that the hole position is accurate with the reference position.

[0033] In this invention, during use, the oil injection ring is placed between the lower support bracket 206 and the upper limit bracket 207. The adjusting bolt 210 is rotated in the forward direction, and the positioning ring 203 is supported by the lower support bracket 206. This eliminates the need for multiple pressure plates to be tightened at multiple points, making the clamping and disassembly of the oil injection ring faster. The servo motor 201 drives the stud 202 to rotate, causing the positioning ring 203 on the side of the upper limit bracket 207 to descend. This further drives the adjusting module 205 and the upper limit bracket 207 to descend, so that the upper limit bracket 207 presses down on the oil injection ring. This prevents the oil injection ring from suddenly slipping or shifting due to improper force applied by the operator. The oil injection ring remains stable during the clamping process and will not cause positioning deviation due to slippage, ensuring accurate EDM drilling position.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
