Description

Technical Field

[0001] This utility model belongs to the field of engine oil cooling test technology, and in particular relates to an engine bench engine oil cooling test device. Background Technology

[0002] An oil cooling test apparatus is a device used to evaluate the cooling performance of engine oil under specific conditions. Existing oil cooling test apparatuses usually deliver the engine oil to a cooling tank and use air cooling for the cooling test. However, air cooling has low cooling efficiency, requires a long time to cool the engine oil, and not only does it consume a lot of cold air, but it also leads to uneven cooling of the engine oil, thus affecting the cooling test results. Summary of the Invention

[0003] The purpose of this invention is to provide an engine bench oil cooling test device. By setting up a cooling component, specifically, the engine oil is delivered into a serpentine tube, and the coolant is delivered into a distribution pipe and sprayed out from several nozzles, thereby cooling the engine oil in the serpentine tube. The water cooling method can improve the cooling efficiency. At the same time, the motor drives the turntable to rotate slowly, and the push shaft will push the fixed frame back and forth, adjusting the position of the distribution pipe, which can cool the serpentine tube from multiple directions, improve the cooling effect, and make the cooling more uniform. This solves the problem that the existing engine oil cooling test devices usually deliver the engine oil into a cooling tank and use air cooling for cooling tests, which has low cooling efficiency and requires a long time to cool the engine oil.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an engine bench oil cooling test device, comprising a bench, a bracket fixedly connected to the top right side of the bench, an oil reservoir fixedly connected to the bracket, an oil pump fixedly connected to the bottom of the oil reservoir, an oil delivery pipe fixedly connected to the oil outlet at the bottom of the oil pump, a cooling assembly arranged on the left side of the bracket, the cooling assembly including a cooling box fixedly connected to the top of the bench, a cover plate fixedly connected to the top of the cooling box by bolts, a motor fixedly connected to the top of the cover plate, a partition fixedly connected to the inner wall of the cooling box, a serpentine tube arranged at the top of the partition plate, a diverter tube arranged above the serpentine tube, several nozzles fixedly connected to the bottom of the diverter tube, fixing blocks fixedly connected to the left and right sides of the diverter tube, a fixing frame fixedly connected to the side of two fixing blocks that are close to each other, a turntable fixedly connected to the bottom output end of the motor, and a push shaft fixedly connected to the bottom of the turntable; a coolant storage tank is formed between the bottom of the partition plate and the cooling box for storing coolant, and the serpentine tube can increase the flow time of the oil in the cooling box, thereby improving the cooling effect.

[0006] Furthermore, the partition has drainage grooves on both the left and right sides. One end of the serpentine tube on the left and one end on the right both penetrate the cooling tank and extend to the outside. One end of the serpentine tube on the right is fixedly connected to the oil delivery pipe at the bottom of the oil pump. One end of the serpentine tube on the left is fixedly connected to an adjusting pipe. One end of the adjusting pipe on the left is fixedly connected to a connecting pipe. One end of the connecting pipe is fixedly connected to the top of the oil storage tank. The drainage grooves are used to return the sprayed coolant to the coolant storage tank at the bottom of the partition, thereby achieving the function of recycling.

[0007] Furthermore, the fixing frame has a sliding groove inside, the push shaft is slidably connected inside the sliding groove, and sliding rods are slidably connected inside both fixing blocks. The front and back of the sliding rods are fixedly connected to the inner wall of the cooling box. A hose is fixedly connected to the front of the distribution pipe, and a liquid pump is fixedly connected to the front of the cooling box. A delivery pipe is fixedly connected to the top outlet of the liquid pump. One end of the delivery pipe passes through the cooling box and is fixedly connected to the front of the hose. By setting the hose, the coolant can be delivered smoothly without affecting the movement of the distribution pipe. The sliding rods are used to support the distribution pipe.

[0008] Furthermore, a connecting frame is fixedly connected to the inner wall of the regulating tube, a limiting rod is slidably connected inside the connecting frame, a square strip is fixedly connected to the top of the limiting rod, a sealing plug is fixedly connected to the right side of the limiting rod, a spring is sleeved on the outside of the limiting rod, the left side of the spring is fixedly connected to the right side of the connecting frame, and the right side of the spring is fixedly connected to the left side of the sealing plug; the square strip on the limiting rod is used to limit the movement of the sealing plug in a linear manner.

[0009] Furthermore, a wedge block is fixedly connected to the top left side of the sealing plug, a threaded rod is threadedly connected to the top of the adjusting tube, a throttle is fixedly connected to the top of the threaded rod, a circular push block is fixedly connected to the bottom of the threaded rod, the right side of the sealing plug is conical, the side of the wedge block facing the circular push block is inclined, and the outer surface of the circular push block contacts the inclined surface on the wedge block; since the wedge block has an inclined surface, when the circular push block moves downward, it will push the sealing plug through the inclined surface.

[0010] This utility model has the following beneficial effects:

[0011] This invention features a cooling assembly that delivers engine oil into a serpentine tube and coolant into a distribution pipe, which is then sprayed out from several nozzles to cool the engine oil inside the serpentine tube. This water-cooling method improves cooling efficiency. Simultaneously, starting a motor drives a turntable to rotate slowly, which in turn pushes the fixing bracket back and forth, adjusting the position of the distribution pipe. This allows for multi-directional cooling of the serpentine tube, improving the cooling effect and making the cooling more uniform.

[0012] This invention features an adjusting tube. Specifically, rotating the handle clockwise causes a circular pusher to move downwards via a threaded rod. As the circular pusher moves downwards, it pushes an inclined block, which in turn moves a sealing plug closer to the left side of the partition. This reduces the size of the opening on the left side of the serpentine tube, thereby lowering the oil flow rate. This method allows the oil to remain in the serpentine tube for a longer period, improving the cooling effect, and can be adjusted according to different cooling requirements.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Please see Figures 1-5 As shown, this utility model is an engine bench oil cooling test device, including a bench 1. A bracket 11 is fixedly connected to the top right side of the bench 1. An oil reservoir 111 is fixedly connected to the bracket 11. An oil pump 112 is fixedly connected to the bottom of the oil reservoir 111.

The cooling assembly 12 includes a cooling box 121 fixedly connected to the top of the bench 1. A cover plate 122 is fixedly connected to the top of the cooling box 121 by bolts. A motor 123 is fixedly connected to the top of the cover plate 122. A partition 124 is fixedly connected to the inner wall of the cooling box 121. A serpentine tube 125 is arranged at the top of the partition 124. A diverter pipe 13 is arranged above the serpentine tube 125. A plurality of diverter pipes are fixedly connected to the bottom of the diverter pipe 13. The nozzle 135 and the diversion pipe 13 are fixedly connected to the left and right sides of the diversion pipe 13, and the two fixed blocks 131 are fixedly connected to the side of the two fixed blocks 131 that are close to each other. The bottom output end of the motor 123 is fixedly connected to the turntable 231, and the bottom of the turntable 231 is fixedly connected to the push shaft 232. After the oil is delivered into the serpentine pipe 125, the coolant is delivered into the diversion pipe 13 and sprayed out from several nozzles 135, thereby cooling the oil in the serpentine pipe 125. The cooling efficiency can be improved by water cooling. At the same time, the motor 123 is started to drive the turntable 231 to rotate slowly, and the push shaft 232 will push the fixation frame 132 back and forth, so that the position of the diversion pipe 13 is adjusted, which can cool the serpentine pipe 125 from multiple directions, improve the cooling effect, and make the cooling more uniform.

[0024] The partition 124 has drainage grooves 241 on both the left and right sides. The left and right ends of the serpentine tube 125 pass through the cooling box 121 and extend to the outside. The right end of the serpentine tube 125 is fixedly connected to the oil delivery pipe at the bottom of the oil pump 112. The left end of the serpentine tube 125 is fixedly connected to the regulating pipe 14. The left side of the regulating pipe 14 is fixedly connected to the connecting pipe 15. One end of the connecting pipe 15 is fixedly connected to the top of the oil storage tank 111.

[0025] The fixed frame 132 has a sliding groove 133 inside, and the push shaft 232 is slidably connected inside the sliding groove 133. The two fixed blocks 131 are slidably connected to the sliding rods 134. The front and back of the sliding rods 134 are fixedly connected to the inner wall of the cooling box 121. The front of the diversion pipe 13 is fixedly connected to the hose 136. The front of the cooling box 121 is fixedly connected to the liquid pump 211. The top outlet of the liquid pump 211 is fixedly connected to the delivery pipe 212. One end of the top of the delivery pipe 212 passes through the cooling box 121 and is fixedly connected to the front of the hose 136.

[0026] A connecting frame 141 is fixedly connected to the inner wall of the regulating pipe 14. A limit rod 142 is slidably connected inside the connecting frame 141. A square strip is fixedly connected to the top of the limit rod 142. A sealing plug 143 is fixedly connected to the right side of the limit rod 142. A spring 144 is sleeved on the outside of the limit rod 142. The left side of the spring 144 is fixedly connected to the right side of the connecting frame 141, and the right side of the spring 144 is fixedly connected to the left side of the sealing plug 143. A wedge block 145 is fixedly connected to the top left side of the sealing plug 143. A threaded rod 146 is threadedly connected to the top of the regulating pipe 14. A handle 147 is fixedly connected to the top of the threaded rod 146. A circular push block 148 is fixedly connected to the bottom of the threaded rod 146. The right side of the plug 143 is conical, and the side of the inclined block 145 facing the circular push block 148 is inclined. The outer surface of the circular push block 148 contacts the inclined surface on the inclined block 145. Turning the handle 147 clockwise drives the circular push block 148 downward through the threaded rod 146. When the circular push block 148 moves downward, it pushes the inclined block 145, which in turn drives the plug 143 closer to the left side of the partition 124. At this time, the opening size on the left side of the serpentine tube 125 is reduced, thereby reducing the oil flow rate. This method allows the oil to stay in the serpentine tube 125 for a longer time, improving the cooling effect, and can be adjusted according to different cooling needs.

[0027] One specific application of this embodiment is:

[0028] In use, engine oil is placed in the oil reservoir 111, and coolant is poured into the coolant tank 121 below the baffle 124. The cover plate 122 is then placed on top of the coolant tank 121 and secured with bolts. The push shaft 232 is inserted into the slide groove 133. The oil pump 112 is then started to deliver the engine oil from the oil reservoir 111 through the oil delivery pipe at the bottom of the pump 112 to the serpentine pipe 125. The engine oil flows through the serpentine pipe 125 to the regulating pipe 14, and then back to the oil reservoir 111 through the connecting pipe 15, achieving a circulating flow. The liquid pump 211 is then started to deliver coolant through the delivery pipe 212 and the hose 136 to the distribution pipe 13, and from several spray nozzles... The head 135 sprays out, thereby cooling the oil in the serpentine tube 125. At the same time, the motor 123 is started to drive the turntable 231 to rotate slowly, and the push shaft 232 will rotate along with it. Since the push shaft 232 slides in the slide groove 133, it will push the fixed frame 132. The fixed frame 132 will drive the diverter tube 13 to move forward and backward through the fixed block 131. At this time, the fixed block 131 slides on the slide rod 134. By adjusting the position of the diverter tube 13, the serpentine tube 125 can be cooled from multiple directions, improving the cooling effect and making the cooling more uniform. The sprayed coolant flows back to the bottom of the baffle 124 through the drain 241, playing a circulation role.

[0029] The operator rotates the handle 147 to drive the threaded rod 146 to rotate, causing the circular pusher 148 to move up or down. When the circular pusher 148 moves down, it pushes the inclined block 145, which in turn moves the sealing plug 143 closer to the left side of the partition 124, thereby reducing the oil flow rate. This method allows the oil to stay in the serpentine tube 125 for a longer time, improving the cooling effect. The sealing plug 143 also causes the limiting rod 142 to slide on the connecting bracket 141 and stretches the spring 144. Since the limiting rod 142 has a square bar at the top, it allows the sealing plug 143 to move in a straight line. When the circular pusher 148 moves up, the sealing plug 143 moves to the left under the elastic action of the spring 144, thereby increasing the oil flow rate in the serpentine tube 125. The sealing plug 143 can be adjusted according to different needs to control the oil flow rate.
