Description

Technical Field

[0001] The invention relates to the field of automobile manufacturing, and in particular to a device and method for measuring the height of an automobile leaf spring. Background Art

[0002] The automobile leaf spring is the most traditional elastic element in the automobile suspension system. Generally, the automobile leaf spring is composed of several pieces of alloy spring steel of unequal lengths, forming a group of spring beams similar to equal strength. In the suspension system, in addition to playing a buffering role, when it is placed in the longitudinal direction of the car and one end is connected to the frame with a fixed hinge, it can be responsible for transmitting all forces and moments in all directions, and determining the trajectory of wheel movement, playing a guiding role, so there is no need to set up other guiding mechanisms. In addition, the automobile leaf spring is composed of multiple pieces stacked together. When deformed under load, each piece has relative sliding and generates friction, which generates a certain resistance and promotes the vibration attenuation of the car body. Therefore, this structure does not require a shock absorber.

[0003] During the production and processing of automobile leaf springs, the two ends of the heat-treated leaf spring plates need to be placed on a flat plate, and the highest height from the middle to the flat surface is measured with a ruler, which is the arc height of the spring plate. The detection process requires manual operation and is not convenient for batch arc height detection of leaf spring plates, which affects the efficiency of arc height detection of leaf spring plates.

[0031] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0032] See also Figures 1 to 5 The present invention provides a vehicle leaf spring height measuring device, comprising a base plate 100, a conveying mechanism 200, a positioning mechanism 300 and an arc height measuring mechanism 400.

[0033] Specifically, scale values ​​are set on the bottom plate 100 along its length direction. The conveying mechanism 200 is set close to the surface of the bottom plate 100, and the leaf spring plate 1 is placed on the conveying mechanism 200, and the opening of the leaf spring plate 1 faces the discharge end of the conveying mechanism 200, and the conveying mechanism 200 can convey the leaf spring plate 1 forward along the length of the bottom plate 100.

[0034] The positioning mechanism 300 is disposed at the discharge end of the conveying mechanism 200, and can abut against both ends of the leaf spring plate 1 on the conveying mechanism 200 to prevent the leaf spring plate 1 from moving forward. The arc height measuring mechanism 400 is located at the feeding end side of the conveying mechanism 200 relative to the positioning mechanism 300, and can abut against the highest point of the arc of the leaf spring plate 1 when the positioning mechanism 300 blocks the baffle 210 leaf spring plate.

[0035] When in use, the leaf spring plate 1 is first placed on the conveying mechanism 200 along the width direction of the bottom plate 100, and the opening of the leaf spring plate 1 faces the discharge end of the conveying mechanism 200. The conveying mechanism 200 conveys the conveying mechanism 200 forward. When conveyed to the positioning mechanism 300, the two ends of the leaf spring plate 1 sequentially abut against the positioning mechanism 300, and the leaf spring plate 1 stops moving forward. Then the arc height measuring mechanism 400 is started and abuts against the highest point of the arc of the leaf spring plate 1. At this time, the corresponding values ​​of the scales of the positioning mechanism 300 and the arc height measuring mechanism 400 on the bottom plate 100 are read, and the arc height value of the leaf spring plate 1 can be calculated.

[0036] By adopting the above-mentioned automobile leaf spring height measuring device, the height of the leaf spring plate 1 of the automobile leaf spring of the automobile leaf spring height measuring device can be measured efficiently and accurately, thereby greatly improving production efficiency and saving production costs.

[0037] It should be noted that in this embodiment, the conveying mechanism 200 can be an intermittent conveying mechanism 200, which pauses during the measurement of the arc height measuring mechanism 400. Of course, the conveying mechanism 200 can also be a method in which the interval time of the leaf spring plate 1 conveyed from front to back is adapted to the measurement time of the arc height measuring mechanism 400, and the next leaf spring plate 1 is conveyed after the previous leaf spring plate 1 is measured and taken away. The conveying mechanism 200 can also be a conveyor belt commonly used in the prior art.

[0038] In this embodiment, the positioning mechanism 300 includes a baffle 210 , which is disposed along the width direction of the bottom plate 100 and can resist the two ends of the leaf spring plate 1 on the conveying mechanism 200 .

[0039] As a preferred embodiment, the positioning mechanism 300 further includes a lifting drive member 220 , which is connected to the baffle plate 210 and is used to drive the baffle plate 210 to vertically lift and lower relative to the base plate 100 .

[0040] When in use, when the measurement of a leaf spring plate 1 is completed, the lifting drive 220 drives the baffle 210 to rise and separate from the conveying mechanism 200, and the conveying mechanism 200 continues to convey the leaf spring plate 1 forward, and then the lifting drive 220 drives the baffle 210 to descend to perform the blocking measurement of the next leaf spring plate 1. In this way, the unloading time of the leaf spring plate 1 can be reduced and the measurement effect can be improved.

[0041] In other embodiments, the baffle 210 may be provided in two and arranged symmetrically on the left and right, and the two baffles 210 may be arranged to open and close and rotate by the rotation drive mechanism 410, so as to achieve the same effect.

[0042] In this embodiment, the arc height measuring mechanism 400 includes a driving mechanism 410 and a measuring plate 420. The measuring plate 420 is arranged along the width direction of the bottom plate 100. The driving mechanism 410 is connected to the measuring plate 420, and can drive the measuring plate 420 to abut against the highest point of the leaf spring plate 1 away from the baffle 210 when the leaf spring plate 1 stops on the conveying mechanism 200.

[0043] When the leaf spring plate 1 stops on the conveying mechanism 200, the driving mechanism 410 starts to drive the measuring plate 420 to abut against the highest point of the leaf spring plate 1 away from the baffle 210, and the arc height of the leaf spring plate 1 can be calculated by reading the scale value between the measuring plate 420 and the baffle 210.

[0044] In this embodiment, the driving mechanism 410 includes a guide plate 411, a rectangular slider 412, a rotation power source 413 and a push rod 414. There are two guide plates 411, which are arranged on the bottom plate 100 opposite to the guide plates 411 and located on the left and right sides of the conveying mechanism 200. The guide plate 411 is provided with an arc-shaped first guide groove 415 with an opening facing upward and simultaneously facing one side of the baffle plate 210. A second guide groove 416 is provided at one end of the first guide groove 415 close to the baffle plate 210, and the second guide groove 416 is arranged horizontally.

[0045] Rectangular sliders 412 are fixed at both ends of the measuring plate 420. The two rectangular sliders 412 are slidably arranged in the first guide groove 415, respectively. A connecting rod is fixed on the outer wall of each rectangular slider 412. The push rod 414 is rotatably arranged on the bottom plate 100. The rotary power source 413 is connected to the push rod 414 to drive the push rod 414 to rotate along the guide plate 411. The push rod 414 is provided with a slide groove, and the connecting rod is slidably inserted in the slide groove. When the push rod 414 rotates, the rectangular slider 412 can be pushed by the connecting rod to move along the first guide groove 415 and the second guide groove 416, thereby driving the measuring plate 420 to slide between the two first guide grooves 415 until it abuts against the highest point of the arc of the leaf spring plate 1.

[0046] During use, when the measuring plate 420 is located at the highest position, when the rotating power source 413 rotates clockwise, the measuring plate 420 can be driven to move through the guide plate 411 , the rectangular slider 412 , and the push rod 414 .

[0047] As a preferred embodiment, the measuring plate 420 is provided with scale values ​​along the width direction of the bottom plate 100. In the case of measuring the highest value of the arc, the position of the highest point of the arc in the horizontal direction can be determined most quickly through the scale values ​​set in the horizontal direction, thereby determining whether the highest point of the leaf spring plate 1 is located at the most middle and offset position.

[0048] As a more preferred embodiment, the arc height measurement mechanism 400 further includes a T-shaped shape mapping rod 430. The base plate 100 is arranged horizontally, and each shape mapping rod 430 is provided with a scale along its height direction. A plurality of T-shaped jacks that penetrate front and back are vertically provided on the measuring plate 420, and the large end of the jack is located on the side away from the baffle 210. A shape mapping rod 430 is slidably inserted in each jack, and the small end of the shape mapping rod 430 extends from the small end of the jack, and the end face of the large end of the shape mapping rod 430 is flush with the end face of the large end of the jack.

[0049] When in use, when the measuring plate 420 enters the second guide groove 416, the extended end of the shape mapping rod 430 contacts the leaf spring plate 1. As the measuring plate 420 continues to move forward, the leaf spring plate 1 can push all the shape mapping rods 430 in contact with it to move away from the baffle 210. When the rotary power source 413 stops rotating, the specific arc height value can be calculated by reading the scale between the baffle 210 and the measuring plate 420 and the scale on the shape mapping rod 430. At the same time, the shape and distance of all the pushed shape mapping rods 430 can reflect the shape of the highest position of the leaf spring spring. Through the shape, it can be accurately judged whether the leaf spring spring is flat at this time and the specific position of the unevenness.

[0050] Preferably, a third guide groove 417 extending vertically downward is formed on the guide plate 411 , and the third guide groove 417 is connected to the top end of the first guide groove 415 .

[0051] When the measuring plate 420 is driven to the highest position of the first guide groove 415, as the rotating power source 413 continues to drive the push rod 414 to rotate counterclockwise, the measuring plate 420 can be driven to be parallel to the ground, so that the shape mapping rod 430 can slide and reset by free fall of gravity, which is convenient for the next measurement.

[0052] As a more preferred embodiment, the arc height measurement mechanism 400 further includes an elastic reset member 440, and the elastic reset member 440 is disposed in the large end of the jack. The two ends of the elastic reset member 440 are respectively connected to the large end of the shape mapping rod 430 and the inner wall of the large end of the jack, and when the elastic reset member 440 is in a natural state, the end face of the large end of the shape mapping rod 430 is flush with the end face of the large end of the jack.

[0053] The elastic reset member 440 can further ensure that the shape mapping rod 430 is reset when the pushing force is eliminated. In addition, a ball bearing can be provided between the contact surface of the shape mapping rod 430 and the socket to reduce the friction force of the contact surface of the shape mapping rod 430 and the socket.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
