Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a boring device for a planetary carrier. Background Technology

[0002] The planetary carrier is one of the main components of planetary gear transmission. A reasonable structure for the planetary carrier should be lightweight, rigid, and easy to process and assemble. Common structural forms include integral double-side plate type, separate double-side plate type, and single-side plate type. Among them, the integral double-side plate type has a structure where the upper and lower side walls are circular, and three supports are equidistantly arranged in the middle. The space between the supports is used to install the planetary gears, and the upper and lower side walls need to be machined and bored to the planetary gear mounting positions. In the existing technology, the boring of the planetary carrier is carried out by a single left-right symmetrical clamping or three reverse synchronous motion clamping. The existing clamping devices are only suitable for boring the planetary carrier on one side, and it is necessary to flip and change the wall surface. Moreover, the above-mentioned single clamping method is not stable for the circular planetary carrier. Therefore, a boring device for the planetary carrier is designed. Summary of the Invention

[0013] This invention proposes a boring device for planetary carriers. A bracket in the supporting structure holds the planetary carrier, and an adjusting rod is staggered with the planetary gear mounting opening of the carrier. This allows for adjustment of the planetary carrier's height and rotation during the boring process. An expanding arm in the limiting structure is inserted into the planetary gear mounting opening of the carrier, and then flips in the opposite direction to fit against the inner wall of the mounting opening for limiting. Depending on the processing requirements, raising the planetary carrier and fitting the expanding arm against the lower wall of the planetary gear mounting opening achieves both limiting and fixing, as well as downward clamping and fixing with the bracket. This stable clamping prevents the planetary carrier from moving up and down or rotating left and right, while also suspending the lower part of the planetary carrier, allowing the boring cutter to directly machine the upper and lower sidewalls of the carrier without rotating the wall. The spacing between the three limiting structures is adjustable, making it suitable for machining planetary carriers of various sizes. During processing, coolant can be connected to a cooling component for pouring and cooling the machined area. The beneficial effects are:

[0014] 1. The present invention has height adjustment: the height and rotation of the planetary carrier can be adjusted by the bracket, so that the boring position can be adjusted as needed during the machining process, which improves the flexibility and adaptability of the machining.

[0015] 2. Multi-directional limiting: The expansion arm in the limiting structure can be inserted into the planetary gear mounting port and clamped and limited by pressing down against the lower wall of the mounting port. This ensures the stability of the planetary carrier during processing, prevents it from moving up and down or rotating left and right, and achieves stable fixation by fitting the planetary carrier structure.

[0016] 3. Adaptable to multiple sizes: The spacing between the three limiting structures is adjustable, which means that the clamping mechanism can be used to process planetary carriers of various sizes, improving the versatility and economy of the equipment.

[0017] 4. Improved processing efficiency: The planetary carrier is suspended and fixed, which allows the cutting tool to process the upper and lower side walls of the planetary carrier simultaneously without the need to rotate the wall, thus reducing processing steps and improving processing efficiency.

[0018] 5. Optimized cooling effect: During the machining process, coolant can be connected to the cooling components to achieve pouring and cooling of the machining area, which helps to maintain the cooling effect of the tool, extend the tool life, and also helps to improve the machining quality.

[0034] In a further embodiment, the cooling assembly 2 includes a bracket 21, a second hydraulic cylinder 22, an adjusting slide rail 23, an adjusting slide block 24, a first fixing bolt 25, a second fixing bolt 26, and a cooling water pipe 27.

One end of the cooling water pipe 27 is movably inserted through the other end of the adjusting slide 24, and the cooling water pipe 27 is fixed by the second fixing bolt 26. The cooling water pipe 27 is connected to the cooling water pipe 27 road. The height of the cooling water pipe 27 can be adjusted by the second hydraulic cylinder 22. The spray position of the cooling water pipe 27 can be adjusted by the movement of the adjusting slide 24 in the adjusting slide 23 and the movement of the cooling water pipe 27 in the adjusting slide 24.

[0035] In a further embodiment, the limiting structure 3 includes a limiting seat 31, several bearings 32, a pair of gears 33, a pair of expanding arms 34, a third hydraulic cylinder 35, and a rack 36. The limiting seat 31 has a convex structure with a through-hole in the middle. One end of the limiting seat 31 is higher than the other end. One end of the limiting seat 31 is fixedly mounted on the upper end of the bracket 21, above the support and below the cooling water pipe 27. Several bearings 32 are symmetrically embedded in the upper and lower side walls of the other end of the limiting seat 31. The middle of each pair of gears 33 is fixedly mounted on axle 37. The pair of gears 33 are movably mounted in the other end of the limiting seat 31, and the axles 37 on the gears 33 are fixedly passed through the bearings 32. A pair of expansion arms 34 are symmetrically mounted on the axle 37 of the gear 33 at one end, and are located above the other end of the limiting seat 31. One end of the third hydraulic cylinder 35 is fixedly inserted through the middle of the side wall of one end of the limiting seat 31, and the telescopic end of the third hydraulic cylinder 35 is located inside the limiting seat 31. The left and right sides of the rack 36 are provided with several teeth at equal intervals. One end of the rack 36 is fixedly connected to the telescopic end of the third hydraulic cylinder 35, and the other end of the rack 36 passes through the gears 33. The rack 36 meshes with the gears 33 respectively. The rack 36 moves back and forth through the third hydraulic cylinder 35. The meshing of the rack 36 with the gears 33 drives the gears 33 to rotate in the opposite direction, so as to realize the reverse flipping of the expansion arms 34 for expansion and limiting.

[0036] In a further embodiment, the expansion arm 34 can be reversed via gear 33 to achieve expansion and limiting of the inner wall of the planetary gear mounting port of the planetary carrier to meet design requirements.

[0037] In a further embodiment, the extended support arm 34 can be inserted into the planetary gear mounting port on the side wall of the planetary carrier to meet the design requirements for fixing and achieve stable limiting and fixing.

[0038] In a further embodiment, the cooling water pipe 27 can be cast in a manner corresponding to the planetary carrier.

[0039] Working principle: The base 11 in the bearing structure 1 is fixed on the corresponding processing table. When processing the planetary carrier, the planetary carrier is placed on the bracket 16. The support range can be adjusted by rotating the adjusting bolt 18 and sliding the adjusting rod 17 on the bracket 16 to adjust the diameter of the planetary carrier. The adjusting rod 17 is placed alternately with the planetary gear mounting port of the planetary carrier, and the planetary gear mounting port is aligned with the limiting structure 3.

[0040] Then, by controlling the electric slide rail 14, the three sets of limiting structures 3 on the bracket 21 move synchronously, inserting the expansion arm 34 into the planetary gear mounting port of the planetary carrier. Then, the third hydraulic cylinder 35 in the limiting seat 31 is driven to extend and drive, and the rack 36 moves forward to mesh with the two gears 33, driving the two gears 33 to rotate in the opposite direction through the wheel shaft 37 with the help of the bearing 32, so as to drive the expansion arm 34 to flip to both sides to fit against the left and right side walls of the planetary gear mounting port for limiting, so that the planetary carrier cannot rotate left or right.

[0041] Then, the first hydraulic cylinder 15 inside the rotary table 13 is extended and driven to raise the planetary carrier on the bracket 16, causing the expansion arm 34 to press down on the lower wall inside the planetary gear mounting port, forming a clamping and fixing with the bracket 16, making the overall fixing more stable; then, during the boring process, the rotary table 13 can be rotated by the motor 12 to adjust the machining position of the planetary carrier.

[0042] Since the planetary carrier is suspended by the bracket 16 at this time, and the adjusting rod 17 is interlocked with the planetary gear mounting port, a boring tool can be used to directly drill a hole in the upper wall of the planetary carrier first, and then pass through the hole in the upper wall to directly process the lower wall without turning the wall surface.

[0043] Before processing, adjust the adjusting rod 17 on the bracket 16 and the cooling component 2 according to the dimensions of the planetary carrier to be processed over a long period of time; adjust the height of the cooling water pipe 27 by the second hydraulic cylinder 22 to match the machining of the upper or lower wall boring holes of the planetary carrier; adjust the front and rear position of the cooling water pipe 27 by moving the adjusting slide 24 in the adjusting slide 23 so that it can be close enough to the drilling part and connected to the cooling water supply for spraying cooling. It can be equipped with a solenoid valve to control the corresponding cooling water pipe 27 to spray water when machining the corresponding part; the sliding of the adjusting slide 24 is fixed in the adjusting slide 23 by the first fixing bolt 25, and the spray position of the cooling water pipe 27 can also be adjusted by the extension and retraction of the adjusting slide 24 by the second fixing bolt 26.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
