Description

Technical Field

[0001] This utility model relates to the field of ferrography, and in particular to a multi-parameter adjustment rotation mechanism for ferrography. Background Technology

[0002] A ferrometer is an instrument used for mechanical wear testing and analysis. It separates metal particles from oil using magnetic force and arranges them on a substrate according to particle size, thereby enabling the reading of the relative concentration of particles of different sizes and further analysis of the physical properties of the particles. For example, a ferrometer disclosed in Chinese patent application number CN201620538449.8 has a raised part of its oil sample disk that corresponds to the substrate fabrication device on the ring, solving the problem of low efficiency in fabricating ferrogram slides in existing ferrometers. However, it cannot switch between individual rotation and synchronous rotation, and cannot flexibly switch between individual rotation and synchronous rotation modes according to experimental needs, which limits the diversity and adaptability of experimental design. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a multi-parameter adjustable rotation mechanism for a ferrography instrument, which can switch between individual rotation and synchronous rotation, so that the ferrography instrument can adapt to diverse experimental needs and improve operating efficiency. When performing synchronous movement, two oil samples can be processed at the same time, which makes it easy to ensure that the two glass substrates operate under the same magnetic field strength, rotation speed and oil sample flow conditions, and facilitates direct comparison of abrasive deposition characteristics.

[0004] This utility model also provides a multi-parameter adjustment rotation mechanism for a ferrometer, comprising: a base, a stepper motor fixedly connected inside the base, a first worm gear fixedly connected to the output end of the stepper motor, a first worm wheel meshing with the outside of the first worm gear, a first main shaft fixedly connected inside the first worm wheel, the bottom end of the first main shaft rotatably connected to the base, a synchronous shaft fixedly connected to one end of the first worm gear, a second worm gear slidably connected to the outside of the synchronous shaft, a second worm wheel meshing with the outside of the second worm gear, a second main shaft fixedly connected inside the second worm wheel, the bottom end of the second main shaft rotatably connected to the base, a sleeve rotatably connected to the side surface of the second worm gear, the inside of the sleeve slidably connected to the synchronous shaft via a keyway, the end of the synchronous shaft away from the first worm gear rotatably connected to the base, and magnetic heads fixedly connected to the top ends of both the first and second main shafts penetrating the upper surface of the base, the upper surface of the magnetic heads being provided with a glass substrate. It can switch between individual rotation and synchronous rotation, enabling the ferrography instrument to adapt to diverse experimental needs and improve operational efficiency. When performing synchronous motion, it can process two oil samples simultaneously, ensuring that the two glass substrates operate under the same magnetic field strength, rotation speed, and oil sample flow conditions, facilitating direct comparison of abrasive deposition characteristics.

[0005] According to the multi-parameter adjustment rotation mechanism for a ferrography instrument described in this utility model, two bearings are fixedly connected inside the base, and the exterior of both the first and second main shafts are rotatably connected to the bearings. The bearings can significantly reduce the frictional resistance during the rotation of the first and second main shafts, thereby reducing mechanical wear and extending the service life of the equipment.

[0006] According to the multi-parameter adjustment rotating mechanism for a ferrospectrometer described in this utility model, an oil collecting cylinder is fixedly connected to the upper surface of the base. The oil collecting cylinder is rotatably connected to the outside of the first main shaft and is located outside the magnetic head. The first and second main shafts have the same external structure. The oil collecting cylinder is used to collect abrasive particles and impurities in the lubricating oil, ensuring that the oil sample does not overflow during analysis and maintaining a clean experimental environment. The location of the oil collecting cylinder outside the magnetic head facilitates efficient adsorption and separation of ferromagnetic abrasive particles in the oil sample by the magnetic head.

[0007] According to the multi-parameter adjustment rotation mechanism for a ferrograph described in this utility model, a positioning funnel is fixedly connected to the upper surface of the oil collecting cylinder. The oil collecting cylinder is located outside the glass substrate, and the injection port of the positioning funnel is located at the rotation center of the glass substrate. The design of the positioning funnel makes oil sample injection more convenient and precise. After the oil sample is injected from the rotation center, under the combined action of centrifugal force and magnetic field force, the ferromagnetic and paramagnetic abrasive particles can be arranged according to their size and magnetic field force distribution to form a clear ferrograph.

[0008] According to the multi-parameter adjustment rotation mechanism for a ferrography instrument described in this utility model, a positioning block is fixedly connected to the outside of the sleeve, a guide bar is slidably connected to the outside of the positioning block, the lower surface of the guide bar is fixedly connected to the base, a screw is rotatably connected inside the guide bar, and the outside of the screw is threadedly connected to the positioning block. The guide bar provides guidance for the movement of the positioning block, thereby allowing the screw to drive the positioning block, causing the sleeve and the second worm gear to move.

[0009] According to the present invention, a multi-parameter adjustment rotation mechanism for a ferrometer includes a screw whose end away from the guide bar passes through the interior of the base and is rotatably connected to the interior of the base. An adjustment section is provided at the end of the screw. The base provides rotational support for the screw, preventing lateral displacement.

[0010] According to the multi-parameter adjustment rotation mechanism for a ferrography instrument described in this utility model, an iron frame is fixedly installed on the outside of the base, and a clamping plate is provided inside the iron frame. The clamping plate is used to securely hold the test tubes, preventing them from shaking or slipping during the experiment, thus ensuring the stability and safety of the experimental operation.

[0011] According to the present invention, a multi-parameter adjustment rotation mechanism for a ferrography instrument includes a control panel externally mounted on the base, which is electrically connected to a stepper motor. The control panel can adjust the operating parameters of the stepper motor to adapt to different oil sample analysis needs, optimize the abrasive deposition process, and improve the quality of the ferrography.

[0012] Beneficial effects: Compared with the prior art, this new multi-parameter adjustable rotation mechanism for ferrography can switch between individual rotation and synchronous rotation, enabling the ferrography to adapt to diverse experimental needs and improve operating efficiency. When performing synchronous movement, it can process two oil samples simultaneously, which makes it easier to ensure that the two glass substrates operate under the same magnetic field strength, rotation speed and oil sample flow conditions, and facilitates direct comparison of abrasive deposition characteristics.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a multi-parameter adjustment rotation mechanism for a ferrography instrument, comprising: a base 1, a stepper motor 2 fixedly connected inside the base 1, a first worm 3 fixedly connected to the output end of the stepper motor 2, a first worm wheel 4 meshing with the outside of the first worm 3, a first main shaft 5 fixedly connected inside the first worm wheel 4, the bottom end of the first main shaft 5 rotatably connected to the base 1, a synchronous shaft 6 fixedly connected to one end of the first worm 3, a second worm 7 slidably connected to the outside of the synchronous shaft 6, a second worm wheel 8 meshing with the outside of the second worm 7, a second main shaft 9 fixedly connected inside the second worm wheel 8, the bottom end of the second main shaft 9 rotatably connected to the base 1, and a sleeve 10 rotatably connected to the side surface of the second worm 7. The sleeve 10 is slidably connected to the synchronous shaft 6 via a keyway 13. A positioning block 17 is fixedly connected to the outside of the sleeve 10. A guide bar 18 is slidably connected to the outside of the positioning block 17. The lower surface of the guide bar 18 is fixedly connected to the base 1. A screw 19 is rotatably connected inside the guide bar 18. The outside of the screw 19 is threadedly connected to the positioning block 17. The end of the screw 19 away from the guide bar 18 passes through the inside of the base 1 and is rotatably connected to the inside of the base 1. An adjustment part 20 is provided at the end of the screw 19. The end of the synchronous shaft 6 away from the first worm gear 3 is rotatably connected to the base 1. The top ends of the first spindle 5 and the second spindle 9 both pass through the upper surface of the base 1 and are fixedly connected to a magnetic head 11. A glass substrate 12 is provided on the upper surface of the magnetic head 11.

[0022] Specifically, when two oil samples need to be processed synchronously, rotating the screw 19 causes the positioning block 17 to move along the guide bar 18 and drive the sleeve 10, causing the second worm 7 to move along the outside of the synchronous shaft 6. This allows the protrusion inside the second worm 7 to engage with the keyway 13 of the synchronous shaft 6, making it easier for the synchronous shaft 6 to drive the second worm 7 to rotate. In turn, the second worm 7 drives the second worm wheel 8 and the second main shaft 9 to rotate. At the same time, the magnetic head 11 drives the oil sample outside the glass substrate 12 to rotate centrifugally.

[0023] The base 1 has two bearings 14 fixedly connected inside. The outer surfaces of the first spindle 5 and the second spindle 9 are rotatably connected to the bearings 14. The upper surface of the base 1 is fixedly connected to an oil collecting cylinder 15, which is rotatably connected to the outer surface of the first spindle 5. The oil collecting cylinder 15 is located outside the magnetic head 11. The outer surfaces of the first spindle 5 and the second spindle 9 have the same structure. The upper surface of the oil collecting cylinder 15 is fixedly connected to a positioning funnel 16. The oil collecting cylinder 15 is located outside the glass substrate 12, and the injection port of the positioning funnel 16 is located at the rotation center of the glass substrate 12.

[0024] Specifically, the oil sample is transported by a quantitative pipette to a glass substrate 12 fixed on the upper end face of the magnetic head 11. The magnetic head 11 and the glass substrate 12 rotate under the drive of the transmission mechanism. The first main shaft 5 and the second main shaft 9 respectively cause the magnetic head 11 and the glass substrate 12 to rotate together. Due to centrifugal force, the oil sample flows along the plate to all sides.

[0025] An iron frame 21 is fixedly installed on the outside of the base 1. A clamping plate 22 is provided inside the iron frame 21. A control panel 23 is provided on the outside of the base 1. The control panel 23 is electrically connected to the stepper motor 2.

[0026] Specifically, the clamping plate 22 fixes the experimental equipment, thereby ensuring the stability and safety of the experimental operation. In addition, the control panel 23 realizes precise control of the stepper motor 2 through electrical connection, including functions such as start, stop, and speed adjustment, to ensure the stability and accuracy of the ferrography instrument during operation.

[0027] Working principle: During spectroscopy, the oil sample is transported by a quantitative pipette onto the glass substrate 12 fixed to the upper end face of the magnetic head 11. The stepper motor 2 is started, driving the first worm gear 3 to rotate the first worm wheel 4. The first worm wheel 4 drives the first spindle 5, causing the magnetic head 11 and the glass substrate 12 to rotate together. Due to centrifugal force, the oil sample flows outwards along the substrate. Ferromagnetic and paramagnetic abrasive particles in the oil sample, under the influence of magnetic force, centrifugal force, liquid viscous resistance, and gravity, are deposited on the glass substrate 12 according to the magnetic force distribution. Residual oil is ejected from the edge of the glass substrate 12, collected, and drained into the oil collection cylinder 15. When it is necessary to analyze two... During the synchronous processing of the oil sample, the screw 19 is rotated by the adjusting part 20, which causes the positioning block 17 to drive the sleeve 10 along the guide bar 18, causing the second worm 7 to move along the outside of the synchronous shaft 6. This allows the protrusion inside the second worm 7 to engage with the keyway 13 of the synchronous shaft 6, so that the synchronous shaft 6 can drive the second worm 7 to rotate. In turn, the second worm 7 drives the second worm wheel 8 and the second main shaft 9 to rotate. At the same time, the magnetic head 11 drives the oil sample outside the glass substrate 12 to rotate centrifugally. Finally, after the glass substrate 12 is cleaned, fixed and dried, a ferrography slide is made.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
