Description

Technical Field

[0001] The invention relates to the technical field of flow rate and direction detection, in particular to a universal nozzle flow rate and direction detection device. Background Art

[0002] For gearboxes that use nozzles to lubricate gears and bearings, in order to ensure that the gearbox can operate normally and smoothly, the lubricating oil sprayed from the nozzle must reach the lubrication part at a specified flow rate. Currently, there are two main ways to detect the flow direction of the nozzle.

[0003] One is to customize the tooling and manual visual inspection. For different types of nozzles involved in a certain product, a set of flow direction detection tooling is designed and produced. The nozzle and supporting tooling are pre-installed before the test, and the oil pressure is set. During the test, the lubricating oil is sprayed out through the nozzle and passes through the holes at specific positions on the tooling. The volume of the lubricating oil is measured with an oil receiving box and a measuring cup, and the time taken for the test is recorded to calculate the flow value and finally obtain the nozzle flow direction test results. This method of detecting the target position and the effective flow of the target by manual visual inspection can basically meet the product quality inspection requirements, but with the increase in product types and the diversity of nozzle structures, a set of special detection tooling needs to be designed and produced for each type of nozzle, which has a long cycle, high cost, low efficiency, and is not conducive to tooling and on-site 5S management.

[0004] The other is to use automated testing equipment for testing, which can arbitrarily set the operating range of the nozzle relative to the target and automatically determine the test results. It is simple to operate, has high detection accuracy and operating efficiency, but is expensive and difficult to adapt to new product development and small batch production production models. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a universal nozzle flow direction detection device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a universal nozzle flow direction detection device, comprising an oil collecting pan and a fixed bracket fixed above the oil collecting pan, the top of the fixed bracket is fixedly connected to a nozzle through a large nut, the nozzle is connected to an oil inlet pipe, the inner cavity of the oil collecting pan is fixedly connected to a position adjustment mechanism, the surface of the position adjustment mechanism is movably connected to a target block, the inner cavity of the target block is plugged with a pointer through an oil inlet hole, the inner cavity of the oil inlet hole is connected to the oil collecting pipe, one side of the target block is fixedly connected to an indicating cone, one side of the oil collecting pan is fixedly connected to a transparent fixing frame, the inner cavity of the transparent fixing frame is provided with a clamping groove, the inner cavity of the clamping groove is movably connected with a paperboard, the surface of the transparent fixing frame is slidably connected to a spring rod for limiting the paperboard, the inner cavity of the transparent fixing frame is slidably connected to a distance indicating plate through a sliding groove, and the surfaces of the transparent fixing frame and the distance indicating plate are both provided with scale patterns.

[0010] As a further solution of the present invention: the tip of the indicating cone abuts against the back side of the transparent fixing frame.

[0011] As a further solution of the present invention: the horizontal guide rail, the vertical guide rail and the crossbeam are all engraved with scales.

[0012] Use the large nut to fix the nozzle to the fixed bracket;

[0013] The horizontal rails, vertical rails and crossbeams are all engraved with scales accurate to millimeters to mark the offset of the target block relative to the nozzle in all directions in space;

[0014] The pointer and the target block are separate structures, and the two are clearance-matched. The pointer can be put into or pulled out of the oil inlet hole of the target block as needed;

[0015] When the pointer is placed into the oil inlet hole of the target block, the tip of the pointer can accurately indicate the position of the nozzle on the fixed bracket;

[0016] After the pointer is pulled out of the oil inlet hole of the target block, the drop point of the oil on the target block can be visually observed and the oil can be collected through the oil collecting pipe to measure the flow rate result;

[0017] Adjust the pointer to the nozzle oil outlet position as the injection starting position, determine the relative distance between the nozzle and the target block according to the design requirements, adjust the positions of the vertical guide rail, beam and target block respectively, and the adjustment distance is confirmed by the scales on the horizontal guide rail, vertical guide rail and beam.

[0018] After the vertical guide rail, crossbeam and target block are adjusted into place, they are tightened with the crossbeam fixing bolts, vertical guide rail fixing bolts and target block fixing bolts respectively.

[0019] When testing, the indicator cone is against the back of the transparent fixing frame, the cardboard is inserted into the transparent fixing frame, the cardboard is fixed by the spring rod, and then the position of the distance indicator plate is adjusted according to the position of the cardboard pointed by the indicator cone. The position indicated by the indicator cone is marked with a brush, and the three-dimensional coordinates of the target block can be clearly recorded and counted, making the test results more intuitive.

[0020] The oil collecting pan is made of transparent acrylic plates, which can not only collect scattered lubricating oil, but also visually observe the lubricating oil injection trajectory and landing point position, and confirm the flow direction test results.

[0021] The plug is used to release the lubricant after testing.

[0022] Compared with the prior art, the present invention has the following beneficial effects: by adjusting the position of the target block manually and fixing it quickly and accurately according to the actual working condition of the gearbox lubrication and cooling nozzle, the flow direction of nozzles of different models can be detected, which can especially meet the requirements of new product development and small batch production mode for strong versatility of tooling, greatly reduce the repeated design and procurement of similar tooling, and reduce production costs. The position of the distance indicator plate is adjusted according to the position of the cardboard pointed by the indicator cone, and the position indicated by the indicator cone is marked with a brush. The three-dimensional coordinates of the target block can be clearly recorded and counted, and the test results are more intuitive. During the test, when the target is tilted, the oil inlet forms an angle with the vertical direction. At this time, the coordinates are positioned according to the horizontal state of the indicator cone, and the complete angle information is noted on the whiteboard for illustration.
