Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically to a cooling equipment for machining worm gears of speed reducers. Background Technology

[0002] During the precision machining of worm gears in speed reducers, the friction between the high-speed rotating tool and the workpiece generates a large amount of heat. If the heat is not cooled in time, it can easily lead to deformation or surface burns of the worm gear, affecting machining accuracy. Traditional cooling equipment often uses open spray systems or simple drip trays to collect coolant, which has the following problems: First, the coolant recycling rate is low, and a large amount of coolant is directly discharged with impurities, resulting in resource waste; second, impurities are easily mixed into the coolant, clogging the nozzles or pumps, requiring frequent manual cleaning, which affects production continuity. Therefore, a compact cooling device that can achieve coolant recycling and automatic impurity separation is needed. Utility Model Content

[0003] This utility model aims to solve the above-mentioned technical problems by providing a cooling device for the machining of worm gears in speed reducers.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a cooling device for worm gear processing of a reducer, including a processing table, a trapezoidal table surface fixedly connected to the top center of the processing table, a liquid accumulation tank being excavated on the top of the processing table outside the trapezoidal table surface, and four guide inclined plates being fixedly connected at equal intervals inside the liquid accumulation tank, the guide inclined plates having a structure that is low at both ends and high in the middle, and a drain hole being opened between two adjacent guide inclined plates.

[0005] As a preferred embodiment of this utility model, a drain pipe is fixedly connected to the bottom of the processing table and at a position relative to the drain hole. The top of the drain pipe is connected to the drain hole, and a debris collection bucket is detachably connected to the bottom of the drain pipe via a thread.

[0006] As a preferred embodiment of this utility model, the trapezoidal platform has a large upper and lower structure, and the angle of the inclined planes around the trapezoidal platform is greater than 15 degrees and less than 30 degrees.

[0007] As a preferred technical solution of this utility model, a coolant collection tank is provided below the processing table, and four L-shaped water inlet pipes are fixedly connected at equal intervals to the top of the coolant collection tank. The end of the L-shaped water inlet pipe away from the coolant collection tank is connected to the middle of the drain pipe.

[0008] As a preferred technical solution of this utility model, a delivery pump is fixedly connected to the outer wall of the coolant collection tank. The inlet end of the delivery pump is connected to the coolant collection tank, and a liquid collection pipe is fixedly connected to the outlet end of the delivery pump. The top of the liquid collection pipe passes through the processing table and extends to the top of the trapezoidal table surface. A nozzle is detachably connected to the end of the liquid collection pipe away from the coolant collection tank.

[0009] This invention has the following advantages: the trapezoidal platform guides the coolant into the collection tank, which then flows into the drain pipe through the guide plate and drain hole, and finally into the coolant collection tank through the L-shaped water inlet pipe. Finally, the coolant is pumped out by the delivery pump and sprayed through the nozzles. Compared with the traditional open spray system, coolant consumption is reduced, significantly reducing resource waste and waste liquid treatment costs. The impurity collection tank can be disassembled to collect metal fragments and other impurities in the liquid, preventing impurities from entering the coolant collection tank and delivery pump, extending the equipment maintenance cycle, ensuring the continuous and stable operation of the cooling system, and improving production efficiency.

[0018] A drain pipe 6 is fixedly connected to the bottom of the processing table 1 directly below the drain hole 5, and the top of the drain pipe 6 is connected to the drain hole 5. A debris collection bucket 7 is detachably connected to the bottom of the drain pipe 6 via threads to collect processing debris falling into the drain hole 5, preventing pipe blockage and extending equipment maintenance cycles. The trapezoidal table surface 2 has a top-smaller and bottom-larger structure, so that the angle between its surrounding slopes and the horizontal plane is 15° to 30°. This angle design ensures the stability of the worm gear when it is placed and effectively guides the coolant and debris generated during processing to flow towards the edge of the trapezoidal table surface 2, eventually flowing into the liquid collection tank 3. A coolant collection tank 9 is located directly below the processing table 1. Four L-shaped water inlet pipes 8 are fixedly connected to the top of the coolant collection tank 9 at equal intervals along the circumference. One end of the L-shaped water inlet pipe 8 is connected to the middle of the drain pipe 6, and the other end is connected to the inner cavity of the coolant collection tank 9. It is used to guide the coolant after impurities are separated in the drain pipe 6 to the coolant collection tank 9 for temporary storage, so as to achieve preliminary solid-liquid separation. A transfer pump 10 is fixedly connected to the outer wall of the coolant collection tank 9. The inlet end of the transfer pump 10 is connected to the bottom of the inner cavity of the coolant collection tank 9 through a pipe, and the outlet end is fixedly connected to the liquid extraction pipe 11. The top of the liquid extraction pipe 11 passes through the processing table 1 and extends to the top of the trapezoidal table surface 2. The end away from the coolant collection tank 9 is detachably connected to a nozzle, which is used to extract the coolant temporarily stored in the coolant collection tank 9 and spray it to the processing area to form a coolant recycling system and reduce resource consumption.

[0019] Specifically, in use, the liquid collection tank 3 has four stainless steel guide plates 4 inside, and the drain hole 5 guides the liquid to quickly flow into the drain pipe 6; the bottom of the drain pipe 6 is connected to the debris collection bucket 7 by a thread, which can be unscrewed periodically to clean the impurities; the coolant collection tank 9 is located directly below the processing table and is connected to the middle of the drain pipe 6 by four L-shaped water pipes 8; during processing, the heat generated by the grinding machine is carried away by the coolant sprayed by the nozzle, and the coolant flows into the liquid collection tank 3 along the inclined surface of the trapezoidal table 2, is collected by the guide plates 4 to the drain hole 5, falls into the drain pipe 6, and the impurities settle into the debris collection bucket 7, while the clear liquid enters the coolant collection tank 9; the delivery pump 10 draws the clear liquid and sprays it through the nozzle to achieve cooling and cleaning.
