Description

Technical Field

[0001] The invention relates to the technical field of radiator gap detection and installation guidance, and in particular to a radiator auxiliary installation adjustment tool and a working method thereof. Background Art

[0002] The radiator is a crucial component of an excavator, primarily cooling the engine and hydraulic oil. The fan plays a crucial role in this heat dissipation process. Because the fan is a moving object and the radiator is a fixed object, the installation clearance between the two is particularly important, ensuring both safety and heat dissipation efficiency. Rapidly detecting and adjusting this clearance during assembly significantly impacts production line progress, making improving assembly efficiency a critical technology in excavator production.

[0003] At present, during the installation process of excavator radiators, in order to ensure safety and heat dissipation efficiency, the radial clearance between the radiator wind shield and the fan has standard specifications. Currently, the radial installation clearance between the radiator wind shield and the fan is detected by a feeler gauge.

[0004] Disadvantages of existing technology: The existing assembly inspection method is inefficient, which seriously affects the progress of the production line. At the same time, even if the initial gap inspection is qualified, there will be certain errors when tightening the bolts. Repeated inspections are required to ensure the radial clearance between the radiator windshield and the fan. Summary of the Invention

[0005] In response to the problems existing in the above-mentioned prior art, the present invention provides a radiator auxiliary installation and adjustment tool and a working method thereof. By using a sensor located at the fan axis to detect the distance from the radiator wind shield, accurate and rapid adjustment of the installation gap between the radiator and the fan can be achieved, and the tool can obtain the axis and guide the adjustment of the radiator.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a radiator auxiliary installation and adjustment tool, including: a detection tool, a sensor, a rotating motor, a wiring harness, a controller, a horn, and an LED light. One end of the detection tool is used to be installed on the engine fan shaft, and the sensor is installed on the other end of the detection tool through the rotating motor. Under the rotation of the rotating motor, the data of multiple evenly distributed points on the radiator windshield are read. The sensor is connected to the input end of the controller through the wiring harness, and the rotating motor, the horn, and the LED light are connected to the output end of the controller through the wires. The data collected by the sensor is transmitted to the controller for processing through the wiring harness. After processing, the controller outputs the control results through the horn and the LED light.

[0007] Furthermore, it also includes: a battery and a switch, the battery is connected to the controller via the switch, and the switch controls whether the battery supplies power to the controller.

[0008] Furthermore, the detection tooling is a U-shaped structure, and one end mounted on the engine fan shaft is a C-shaped card structure, which is carded on the engine fan shaft.

[0009] A working method of a radiator auxiliary installation and adjustment tool comprises the following steps: a detection tool with a C-shaped card structure is clamped on the shaft of an engine fan; one end of the detection tool with a rotating motor and a sensor is located at the fan axis; the sensor reads data of multiple evenly distributed points on the radiator windshield under the rotation of the rotating motor, wherein the distance data L includes: L1, L2, L3, L4, L5, L6, L7, ..., Ln; and the direction data α includes: α1, α2, α3, α4, α5, α6, α7, ..., αn; the sensor transmits the multiple data to a controller via a wiring harness; the controller performs calculation and analysis and compares the data with the fan radius data R originally set for the corresponding model; the original clearance is A, and the error is set to ±W.

[0010] Furthermore, if the clearance data |LR| in each direction is ≤W, the LED light will display green, indicating normal assembly; if the clearance data |LR| in one or more directions other than all directions is greater than W, the LED light will display yellow, indicating that the radiator needs to be adjusted, and the horn will prompt to adjust the distance l and the adjustment direction α (X or Y); if the clearance data |LR| in each direction is greater than W, the LED light will display red, and the horn will prompt that normal assembly cannot be achieved by adjusting the radiator.

[0011] Furthermore, the LED lights are green, yellow and red LED lights or LED lights that can emit three colors.

[0012] Furthermore, the data collected by the sensor forms a model. By comparing the distance data L in multiple directions: L1, L2, L3, L4, L5, L6, L7...Ln and the original set fan radius data R to see if the difference |LR| is within the error range W, the distance l and direction α (X or Y) that need to be adjusted in individual directions are compared and accumulated in the X and Y directions through trigonometric calculation.

[0013] Furthermore, the trigonometric function calculation is accumulated in the X and Y directions: lX = (((L1-RAW)*cosα1+(L2-RAW)*cosα2+(L3-RAW)*cosα3+(L4-RAW)*cosα4+(L5-RAW)*cosα5+(L6-RAW)*cosα6+(L7-RAW)*cosα7…+ (Ln-RAW)*cosαn)) / 2, lY = (((L1-RAW)*sinα1+(L2-RAW)*sinα2+(L3-RAW)*sinα3+(L4-RAW)*sinα4+(L5-RAW)*sinα5+(L6-RAW)*sinα6+(L7-RAW)*sinα7…+(Ln-RAW)*sinαn)) / 2.

[0014] Furthermore, the X direction is the forward direction of the entire machine, the Y direction is the upward direction of the entire machine, and a negative value is the reverse direction.

[0015] Furthermore, another auxiliary mode of the controller is turned on at the same time for auxiliary purposes only, controlling the error W to a smaller value V. The same calculation method is used to remind the installer that when the main control mode can be installed normally, further adjusting the distance and direction of the radiator will result in a better installation gap effect.

[0016] The beneficial effects of the present invention are: (1) A sensor located at the fan axis is used to detect and calculate the radial gap between the radiator windshield and the fan, and prompts and guides the radiator installation adjustment distance and direction, so as to achieve accurate and rapid adjustment of the installation gap between the radiator and the fan to meet the requirements of standard specifications; (2) The method of use is simple, the applicability is wide, the assembly efficiency is high, it is suitable for industrial promotion, and the production line assembly efficiency is high.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] like Figure 1 As shown, a radiator auxiliary installation and adjustment tool includes: a detection tool, a sensor, a rotating motor, a wiring harness, a controller, a horn, and an LED light. One end of the detection tool is used to be installed on the engine fan shaft, and the sensor is installed on the other end of the detection tool through the rotating motor. Under the rotation of the rotating motor, the data of multiple evenly distributed points on the radiator windshield are read. The sensor is connected to the input end of the controller through the wiring harness, and the rotating motor, the horn, and the LED light are connected to the output end of the controller through wires. The data collected by the sensor is transmitted to the controller for processing through the wiring harness. After processing, the controller outputs the control results through the horn and the LED light.

[0021] A radiator auxiliary installation and adjustment tool also includes: a battery and a switch. The battery is connected to a controller via the switch. The switch controls whether the battery supplies power to the controller. The battery is provided to facilitate movement and use of the adjustment tool.

[0022] The detection fixture has a U-shaped structure, and one end installed on the engine fan shaft is a C-shaped card structure, which is clamped on the engine fan shaft to achieve quick installation. The C-shaped card structure is an elastic structure, which can make the installation more secure.

[0023] like Figure 1-2As shown, a working method of a radiator auxiliary installation and adjustment tool is shown, wherein a detection tool with a C-shaped card structure is clamped on the shaft of the engine fan, and one end of the detection tool with a rotating motor and a sensor is located at the fan axis. The sensor reads data of multiple evenly distributed points on the radiator windshield under the rotation of the rotating motor, wherein the distance data L is: L1, L2, L3, L4, L5, L6, L7...Ln; the direction data α is: α1, α2, α3, α4, α5, α6, α7...αn; the sensor transmits multiple data to the controller through the wiring harness, and the controller performs calculations Analyze and compare the fan radius data R with the original setting of the corresponding model. The original gap is A and the error is set to ±W. If the gap data |LR| in each direction is ≤W, the LED light will show green and the assembly is normal. If there is a gap data |LR| in one or more directions that are not all directions>W, the LED light will show yellow, indicating that the radiator needs to be adjusted, and the speaker will prompt to adjust the distance l and adjustment direction α (X or Y). If the gap data |LR| in each direction is>W, the LED light will show red, and the speaker will prompt that normal assembly cannot be achieved by adjusting the radiator.

[0024] The LED lights are green, yellow and red LED lights or LED lights that can emit three colors.

[0025] like Figure 3 As shown, the data collected by the sensor forms a model. By comparing the distance data L in multiple directions: L1, L2, L3, L4, L5, L6, L7...Ln and the original set fan radius data R to see if the difference |LR| is within the error range W, the distance l and direction α (X or Y) that need to be adjusted in individual directions are compared and accumulated in the X and Y directions through trigonometric calculation.

[0026] Calculate and accumulate in the X and Y directions through trigonometric functions: lX=(((L1-RAW)*cosα1+(L2-RAW)*cosα2+(L3-RAW)*cosα3+(L4-RAW)*cosα4+(L5-RAW)*cosα5+(L6-RAW)*cosα6+(L7-RAW)*cosα7……+ (Ln-RAW)*cosαn)) / 2, lY=(((L1-RAW)*sinα1+(L2-RAW)*sinα2+(L3-RAW)*sinα3+(L4-RA W)*sinα4+(L5-RAW)*sinα5+(L6-RAW)*sinα6+(L7-RAW)*sinα7……+(Ln-RAW)*sinαn)) / 2.

[0027] The X direction is the forward direction of the whole machine, and the Y direction is the upward direction of the whole machine. Negative values ​​are the reverse direction.

[0028] The controller's other auxiliary mode is simultaneously enabled for auxiliary purposes only, controlling the error W to a minimum value V. Using the same calculation method, the installer is reminded that when the main control mode allows normal installation, further adjustments to the radiator's distance and direction will result in a better installation clearance.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
