Description

Technical Field

[0001] This invention relates to the field of speed reducer processing equipment technology, specifically to a speed reducer and its housing processing equipment. Background Technology

[0002] As the core load-bearing component of the speed reducer, the gearbox housing typically has multiple mounting holes, connection holes, and oil passage holes, requiring high precision due to the large number of holes. Currently, the drilling and machining of gearbox housings mainly faces the following technical challenges:

[0003] First, traditional drilling equipment mostly adopts a single-axis, single-hole, sequential processing method. For processing multiple holes on the same housing, multiple clamping, multiple positioning, and multiple drilling are required, which is cumbersome and has a long processing cycle.

[0004] Secondly, if the large amount of heat and metal shavings generated during the drilling process cannot be discharged in time, they will scratch the machined surface. Continuous drilling will cause the drill bit temperature to rise, accelerate tool wear, and affect the dimensional accuracy and surface roughness of the hole. Therefore, a drilling equipment that can achieve efficient and synchronous multi-hole processing and ensure stable and reliable processing is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a speed reducer and its housing processing equipment, so as to at least partially solve the above-mentioned technical problems.

[0015] Preferably, a plurality of first bearings matching the rotating rod are fixedly installed on the inner side of the lifting plate, the inner ring of the first bearing is fixedly connected to the connecting rod, and a second bearing matching the connecting sleeve is fixedly installed at the bottom of the support base, the outer wall of the connecting sleeve is fixed to the inner ring of the second bearing.

[0016] Preferably, the top of the workbench has a water-gathering tank that surrounds the aforementioned tooling table, and both sides of the water-gathering tank have openings.

[0022] Thirdly, the present invention continuously sprays coolant into the cutting area during the drilling process through the cooling component, which effectively reduces the working temperature of the drill bit and the discharge of metal chips, reduces tool wear, and extends the service life of the drill bit by about 30%.

[0023] Fourth, the present invention filters and recycles the coolant through a filter assembly, thereby separating the coolant from the metal shavings of the drilled product. This facilitates the recycling of the coolant and metal shavings, reducing coolant waste and waste discharge. Attached Figure Description

[0054] A handle 621 is fixedly installed at the outer end of the filter plate 62. The filter plate 62 is a stainless steel sintered plate as a filter element or filter screen. A water collection tank 14 is opened on the top of the workbench 1, which surrounds the above-mentioned tooling table 4. Both sides of the water collection tank 14 are provided with a drain 141. The top of the filter box 61 is provided with a through-hole that connects to the multiple drains 141. The water collection tank 14 is trapezoidal.

[0055] The filter box 61 has a rectangular box structure. Its top is fixedly connected to the bottom of the workbench 1 and communicates with the space above the workbench 1 through a drain 141 on the workbench 1. The filter plate 62 is horizontally arranged inside the filter box 61, with one end of the filter plate 62 extending outward to the outside of the filter box 61. A handle 621 is fixedly provided on the outer end of the filter plate 62 for easy removal, replacement, or cleaning by the operator. The filter plate 62 uses a sintered stainless steel plate as the filter element, or a stainless steel filter screen can be used.

A drain pipe 63 is provided on the outer wall of the filter box 61 below the filter plate 62.

[0056] The top of the workbench 1 has a water collection tank 14 that surrounds the tooling table 4. The water collection tank 14 is located outside the area of ​​a large amount of splashing liquid. The trapezoidal lower part of the water collection tank 14 has outlets 141 on both sides, and the two sides of the water collection tank 14 are gradually sloping downwards. The outlets 141 penetrate the upper and lower surfaces of the workbench 1. The top of the filter box 61 has an opening that connects to the multiple outlets 141. During drilling, the coolant sprayed carries metal scraps across the surface of the workbench 1, collects in the water collection tank 14, and then flows into the filter box 61 below through the outlets 141.

[0057] More preferably, the inner wall of the filter box 61 is provided with a guide groove 711 that matches the edge of the filter plate 62, and the two sides and the tail end of the filter plate 62 are respectively inserted into the guide groove 711.

[0058] The guide groove 711 opened in the inner wall of the filter box 61 is used for the filter plate 62 to slide inside the filter box 61 and be detached, while limiting the installation of the filter plate 62 inside the filter box 61 to filter the coolant above.

[0059] A specific application of this embodiment is as follows: First step: The operator places the reducer housing 5 to be processed on the tooling table 4 on the top of the workbench 1. The reducer housing 5 is positioned by matching and fixing the boss on the tooling table 4 with the bottom of the reducer housing 5. Alternatively, the reducer housing 5 can be clamped and fixed on the tooling table 4 by adding an external clamping device or a vacuum adsorption device to ensure that the reducer housing 5 does not shift during the drilling process.

[0060] Step 2: Based on the material of the reducer housing 5 and the specifications of the hole to be processed, set the speed of the drive motor 31 and the feed speed of the cylinder 22, and start the equipment;

[0061] Step 3: The drive motor 31 starts, and its output shaft drives the rotating disk 33 to rotate via the connecting flange 32. The gear ring 36 on the inner ring of the rotating disk 33 rotates synchronously with the rotating disk 33. The gear ring 36 drives each gear 37 to rotate synchronously through meshing. Each gear 37 drives the corresponding rotating rod 38 to rotate, and the rotating rod 38 drives the drill bit 35 at the bottom to rotate synchronously through the connecting sleeve 34. Since each gear 37 meshes with the same gear ring 36, the rotation speed of each drill bit 35 is exactly the same, achieving synchronous rotation of multiple drill bits 35.

[0062] Step 4: The cylinder 22 of the lifting assembly 2 is activated, and the telescopic end of the cylinder 22 extends upward, pushing the lifting plate 13 to slide upward along the support rod 11 via the irregular connecting plate 23. During the upward movement of the lifting plate 13, the support base 131, the connecting sleeve 34, and the drill bit 35 are all raised as a whole. While maintaining high-speed rotation, each drill bit 35 feeds upward, synchronously contacting the part to be processed on the reducer housing 5, and performing multi-hole synchronous drilling on the connecting part of the reducer housing 5.

[0063] Step 5: During drilling, the water pump 75 of the cooling assembly 7 pumps the coolant from the water tank 71. After being distributed by the water distribution ring 72, the coolant is sprayed onto the cutting area of ​​each drill bit 35 by each nozzle 73. The coolant cools and lubricates the drill bit 35 and the workpiece, while simultaneously flushing away metal chips generated during drilling from the cutting area. The coolant carrying the chips flows across the surface of the worktable 1, collects in the water collection tank 14, and flows into the filter box 61 through the drain 141. The filter plate 62 in the filter box 61 intercepts the metal chips in the coolant, and the clean coolant is discharged through the drain pipe 63 after passing through the filter plate 62, and can be returned to the water tank 71 for recycling.

[0064] Step 6: After drilling reaches the preset depth, the telescopic end of cylinder 22 retracts downward, causing the lifting plate 13 to descend and reset, and the drill bit 35 disengages from the machined hole. The drive motor 31 stops rotating, the external clamping device releases the workpiece, and the operator removes the machined reducer housing 5 from the tooling table 4, completing one work cycle.
