Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of oil return pipe, specifically to a detection device of engine supercharger oil return pipe. BACKGROUND

[0002] The oil return pipe usually has multiple bending points, and the overall structure is relatively irregular, so the detection process mainly relies on manual completion.

[0003] In the case of only using ordinary measuring tools for manual detection, the efficiency is low and the accuracy cannot be guaranteed. Therefore, a special gauge needs to be designed.

[0004] CN110455148A discloses a detection mold of engine inlet and return oil pipe for assisting in detecting whether the return oil pipe is qualified. The deficiency of the detection device is that the function is single, and only the relative position of the adjacent straight pipe sections at the corner can be detected, and multiple detection points need to be loaded during use, which is complicated to operate.

[0005] In addition, the existing return oil pipe detection device has a single function and is difficult to realize rapid detection, especially the overall qualified evaluation of the return oil pipe needs to be combined with multiple tools, which also brings inconvenience to the detection work. UTILITY MODEL CONTENTS

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 The present invention provides a technical solution comprising: a base plate 1, on which a rubber support 2 is fixed, and a groove 3 is provided on the rubber support 2. The groove 3 is used to place the return oil pipe. One end of the rubber support 2 is provided with a fixing plate 4 fixed on the base plate 1. The fixing plate 4 is provided with screw holes 5. The other end of the rubber support 2 is provided with a slide rail 6 fixed on the end face of the base plate 1. The slide rail 6 is provided with a slide groove 7. A lifting component is slidably connected inside the slide groove 7. A support plate 8 is fixed to the end of the lifting component away from the slide rail 6. A connecting pipe is fixed to one end of the support plate 8. The connecting pipe is inserted into the other end of the return oil pipe.

[0031] The rubber support 2 is used to clamp the return oil pipe for inspection. The rubber support 2 has a certain degree of elasticity, allowing it to clamp return oil pipes of different specifications. A pressure block 9 is screwed to the top of the rubber support 2, and the end of the pressure block 9 facing the rubber support 2 has a pressure groove 10. The pressure block 9 is used to fix the top of the return oil pipe, ensuring its complete and stable fixation. The fixing plate 4 has a through hole 11 inside, which coincides with the center of the clamping groove 3. The through hole 11 is used for water introduction.

[0032] A water flow meter 12 is inserted inside the connecting pipe. The connecting pipe, the return oil pipe, and the through hole 11 form a water circuit. In order to detect the blockage of the return oil pipe, water can be injected along the through hole 11. After passing through the return oil pipe, the water is led out through the connecting pipe. The water flow meter 12 is inserted inside the connecting pipe to detect the water flow rate. By comparing the flow rate with the standard return oil pipe flow rate, the blockage detection result can be obtained.

[0033] The connecting pipe is used to connect the return oil pipe to the fixed plate 4. Since the return oil pipe has different shapes and bends, the position of the connecting pipe needs to be adjusted when testing the connection stability of return oil pipes of different specifications. Then, a lead screw 13 is rotatably connected inside the slide groove 7. One end of the lead screw 13 extends along the end face of the slide rail 6, and the first rotating disk 14 is fixed to the extended end of the lead screw 13.

[0034] The lifting component includes a sliding block 15 outside the threaded connecting screw 13. A first vertical rod 16 is fixed to the top of the sliding block 15. A second vertical rod 17 is sleeved outside the first vertical rod 16. The end of the second vertical rod 17 away from the first vertical rod 16 is fixed to the bottom of the support plate 8. The first vertical rod 16 slides inside the second vertical rod 17. A first connecting rod 18 is hinged to the top of the first vertical rod 16. A second connecting rod 19 is hinged to the inside of the second vertical rod 17. A rotating seat is hinged to the end of the first connecting rod 18 away from the first vertical rod 16 and the end of the second connecting rod 19 away from the second vertical rod 17. An adjusting screw 20 is fixed to the side of the rotating seat. The adjusting screw 20 is threaded to the side of the second vertical rod 17. A second rotating disk 21 is fixed to the end of the adjusting screw 20 extending out of the side of the second vertical rod 17.

[0035] When the first rotating disk 14 rotates, it can drive the lead screw 13 to rotate. After the lead screw 13 rotates, the sliding block 15 threaded to it can be adjusted laterally, thereby changing the position of the support plate 8. After the adjusting screw 20 is screwed in, it can touch the rotating seat. When the rotating seat rotates, the two ends of the first connecting rod 18 and the second connecting rod 19 hinged to it begin to rotate, thereby touching the first vertical rod 16 and moving downward. Correspondingly, the second vertical rod 17 moves upward. When the adjusting screw 20 is screwed out, the second vertical rod 17 moves downward, thereby driving the support plate 8 to rise and fall for adjustment.

[0036] The working principle of this utility model is as follows: The straight section of the return oil pipe is clamped and fixed inside the rubber support 2. The two ends of the return oil pipe are respectively fixed to the fixing plate 4 with screws and to the connecting pipe. The position of the connecting pipe can be adjusted. When testing return oil pipes of different specifications, the position can be adjusted first, and then the return oil pipe can be installed to check whether the return oil pipe can be installed stably. At the same time, water can be injected along the through hole 11 on the fixing plate 4 to check the blockage inside the return oil pipe.
