Description

Technical Field

[0001] The utility model belongs to the field of automobile front side panel detection devices, in particular to an automobile front side panel detection device. Background Art

[0002] The front side panel of a car is the structural frame that fixes the car headlights. It is installed inside the car shell and is usually an irregular part welded from several plates. After the front side panels of a car are processed and shipped out of the factory, the front side panels of the same batch need to be quality inspected. Sampling inspection is usually adopted to ensure the quality of this batch of products, thereby ensuring the overall quality of the subsequent front side panels installed on the vehicle.

[0003] The Chinese patent with the authorization announcement number CN211876894U discloses a detection device for the front side panel of an automobile, including a reference platform; a plurality of positioning components, which are installed on the reference platform and are used to position the front side panel of the automobile to be detected; a plurality of clamping components, which are installed on the reference platform and are used to clamp the front side panel of the automobile to be detected; and a plurality of hole position detection components, which are used to detect the hole position accuracy of the front side panel of the automobile after positioning and clamping. With this structure, the positioning component can position the front side panel of the automobile to determine the relative position of the front side panel of the automobile to be detected on the reference platform, and then the front side panel of the automobile can be clamped by a plurality of clamping components, so as to facilitate the detection of the hole position accuracy.

[0004] However, since the front side panel of the car is installed on the vehicle, once the car collides during driving, pressure will be exerted on the front side panel of the car, and the front side panel of the car is welded and processed by several different panels. If there are defects in the design and processing of the front side panel of the car, the structural strength and compressive strength of the front side panel of the car will be low, so that the front side panel of the car will be damaged when the car has a lighter collision, and the design indicators will not be met, and the maintenance cost of the car will be increased unnecessarily.

[0005] However, the above patent cannot test the structural strength and compressive strength of the front side panel of the car, and cannot ensure and test the quality of the same batch of products. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0028] A detection device for a front side panel of an automobile comprises a cabinet body 11 and a floating plate 13, wherein a panel 10 is fixedly connected to the cabinet body 11, the floating plate 13 is floatingly arranged above the panel 10, the upper side of the floating plate 13 is fixedly connected to two mounting seats 18, and the bottom side of the floating plate 13 is provided with two mutually perpendicular and intersecting slide grooves 14, each of which is symmetrically distributed and slidably connected with a group of sliders 15, each of which is fixedly connected with a ball head seat 16 at the bottom, and an electric drive cylinder 17 is fixedly connected at a corresponding position of each ball head seat 16 in the panel 10, the end of the extended end of the electric drive cylinder 17 is spherical, and the extended end of each electric drive cylinder 17 is movably connected to the ball head seat 16.

[0029] Two mounting seats 18 are fixedly connected to the floating plate 13 , and the front side panels 12 of the vehicle are fixedly mounted on the two mounting seats 18 . The front side panels 12 of the vehicle are respectively connected to the two mounting seats 18 through two groups of bolts.

[0030] Two groups of columns 19 are fixedly connected at both ends of the panel 10, and a first screw 20 is rotatably connected between the tops of each group of columns 19. Two first screws 20 are respectively threadedly connected to two mutually symmetrical first screw slides 21, and two second screws 22 are rotatably connected between the two first screw slides 21, and second screw slides 23 are threadedly connected to the two second screws 22.

[0031] A cylinder 24 is fixedly connected to the second screw slide 23 , and the extended end of the cylinder 24 faces the front side plate 12 of the automobile. A pressure head 25 is fixedly connected to the end of the extended end of the cylinder 24 .

[0032] One end of each first lead screw 20 extending out of the column 19 is fixedly connected to the first synchronous wheel 28, and a first synchronous belt 29 is transmission-connected between the two first synchronous wheels 28, and one end of one of the first lead screws 20 away from the first synchronous wheel 28 is transmission-connected to the first motor 26 fixedly connected to the column 19, and one end of each second lead screw 22 extending out of the first lead screw slide 21 is fixedly connected to the second synchronous wheel 30, and a second synchronous belt 31 is transmission-connected between the two second synchronous wheels 30, and one end of one of the second lead screws 22 away from the second synchronous wheel 30 is transmission-connected to the second motor 27 fixedly connected to the first lead screw slide 21.

[0033] In this embodiment, initially, the operator connects the power supply and control system of this patent, and connects the cylinder 24 to the air pump outside of this patent, and then the staff places the front side panels 12 of the automobiles extracted from the front side panels 12 of the automobiles produced in the same batch on the two mounting seats 18, and inserts two sets of bolts into the holes of the front side panels 12 of the automobiles and fixes them on the mounting seats 18, thereby stably fixing the front side panels 12 of the automobiles.

[0034] At this time, the cylinder 24 is above the front side panel 12 of the automobile. The operator can inject air into the cylinder 24 by controlling the air pump, so that the extended end of the cylinder 24 moves toward the front side panel 12 of the automobile with the pressure head 25, and the pressure head 25 presses on the front side panel 12 of the automobile to apply pressure to the pressure head 25, so as to stop after the front side panel 12 of the automobile is irreversibly deformed or directly damaged, so as to detect the maximum pressure that the front side panel 12 of the automobile can bear, so as to facilitate the understanding of the design defects of the front side panel or the processing defects during processing, so that the factory can make targeted adjustments.

[0035] In the actual use scenario of the automobile front side panel 12, since the automobile front side panel 12 is installed on the vehicle, when a collision occurs during driving of the vehicle, the position and angle of the pressure exerted on the automobile front side panel 12 are not unique. Therefore, when testing the structural strength and pressure resistance of the automobile front side panel 12, it is necessary to simulate the actual scenario and apply pressure at different angles and positions for testing.

[0036] When adjusting the angle of applied pressure, the operator controls each electric drive cylinder 17 to extend or retract through the control system. When one of the two electric drive cylinders 17 in the same group extends and the other retracts, the floating plate 13 and the front side plate 12 of the vehicle are tilted toward the retracted electric drive cylinder 17. By controlling the extension and retraction amount of the electric drive cylinder 17, different tilt angles can be accurately adjusted.

[0037] When the electric cylinder 17 extends or retracts, the distance between the two sliders 15 in the same group changes. During this process, the slider 15 slides in the corresponding slide groove 14 to avoid hindering the extension and retraction of the electric cylinder 17.

[0038] Since the ball head at the end of the electric drive cylinder 17 is movably connected to the ball head seat 16, when the slider 15 and the ball head seat 16 tilt with the floating plate 13, there is no obstruction or interference between the end of the electric drive cylinder 17 and the ball head seat 16, ensuring that the floating plate 13 and the front side plate 12 of the car can tilt smoothly.

[0039] Furthermore, since the two groups of electric cylinders 17 are perpendicular to each other, the floating plate 13 and the front side plate 12 of the vehicle can be tilted in two directions, and the two groups of electric cylinders 17 can be simultaneously controlled to extend and retract to different degrees, so that the tilting trends in the two directions are superimposed, so that the front side plate 12 of the vehicle and the floating plate 13 can be freely tilted in all directions, and the tilting angle is stable and controllable.

[0040] When adjusting the position of applied pressure, the operator can drive the first screw 20 and the second screw 22 to rotate respectively through the control system. When the first screw 20 rotates, it can drive the two first screw slides 21 to move synchronously along the axial direction of the first screw 20, and when the second screw 22 rotates, it can drive the second screw slide 23 to move along the axial direction of the second screw 22, so that the position of the cylinder 24 can be freely adjusted in the horizontal direction to simulate the pressure applied to different positions of the front side panel 12 of the car for detection.

[0041] When driving the first screw 20 to rotate, the first motor 26 only directly drives one first screw 20 to rotate, and the two first screws 20 are driven by the transmission between the first synchronous wheel 28 and the first synchronous belt 29, so that the two first screws 20 rotate synchronously and stably, so as to improve the stability and accuracy of driving the first screw slide 21 to move. Similarly, the second motor 27 only drives one second screw 22 to rotate, and the two second screws 22 are driven by the transmission between the second synchronous wheel 30 and the second synchronous belt 31, so that the two second screws 22 rotate synchronously and stably, thereby ensuring that the second screw slide 23 and the cylinder 24 move stably and accurately.

[0042] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0043] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
