DETAILED DESCRIPTION

[0024] The following embodiments of the technical solution of the utility model 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 utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0025] See also Figures 1 to 4 The utility model provides a frame shock absorption testing device, including a base 100, an intermittent pressing device 200 and a distance measuring device 300.

[0026] Specifically, the base 100 is used to support the frame 1. The intermittent pressing device 200 can intermittently press the frame 1 on the base 100, and the frame 1 rebounds and resets during the interval between two pressings. The distance measuring device 300 is provided with a scale, and the distance measuring device 300 is arranged on the base 100 and connected to the frame 1 on the base 100, and can move with the frame 1, and the moving distance can be reflected by the scale on it.

[0027] When in use, the frame 1 to be tested is placed on the base 100, and then the intermittent pressing device 200 is started to intermittently press the frame 1 downward. After each pressing and releasing, the frame 1 rebounds once. The moving distance of the reaction on the distance measuring device 300 can be measured, and the shock absorption of the frame 1 can be directly reflected according to each rebound distance. At the same time, each rebound distance can be accumulated and calculated, and the average single rebound distance can be obtained by dividing the total distance by the number of pressing times, so that the shock absorption of the frame 1 can be accurately measured.

[0028] In this embodiment, the intermittent pressing device 200 includes a support frame 210, a telescopic power source 220 and a pressing plate 230. The support frame 210 is vertically arranged on the base 100, the telescopic power source 220 is arranged on the support frame 210, and the pressing plate 230 is connected to the telescopic power source 220. The telescopic power source 220 can drive the pressing plate 230 to press on the frame 1 with regular gaps perpendicular to the base 100. In a specific embodiment, the telescopic power source 220 can be a hydraulic or pneumatic telescopic cylinder commonly used in the prior art.

[0029] During use, when the telescopic power source 220 is activated, the pressing plate 230 is driven to press down and impact the frame 1 and then retract upward, and the frame 1 can rebound naturally, thereby objectively reflecting the shock absorption performance of the frame 1.

[0030] In this embodiment, the distance measuring device 300 includes a connecting member 310, a toggle member 320 and a scale bar 330 provided with a scale. The connecting member 310 can be detachably fixed to the frame 1. The toggle member 320 is arranged on the connecting member 310. The scale bar 330 is arranged perpendicular to the base 100 and can move in a direction perpendicular to the base 100. The side wall of the scale bar 330 is provided with a plurality of teeth at intervals along its length direction. The toggle member 320 can be inserted between any two adjacent teeth and toggle the scale bar 330 to move through the teeth.

[0031] When in use, when the connecting member 310 is connected to the frame 1, when the frame 1 is pressed down or rebounds, the rack can be driven to move, and the rebound distance can be calculated intuitively and accurately through the scale on the ruler 330.

[0032] As a preferred embodiment, the ruler 330 can only move in a direction away from the base 100 through the teeth. That is, it can only move when the frame 1 rebounds, so the number of multiple rebounds can be accumulated. By accumulating data and the number of pressing impacts, the shock absorption performance can be accurately measured, further reducing measurement errors.

[0033] Specifically, the toggle member 320 includes a rod body 321 and a stopper 322. The rod body 321 is hinged on the connecting member 310 and can be inserted between any two adjacent teeth. The stopper 322 is fixed on the connecting member 310 and is disposed adjacent to the rod body 321 and is located close to the base 100.

[0034] When the telescopic power source 220 starts to drive the pressure plate 230 to press the frame 1, when the frame 1 moves toward the bottom plate, the rod body 321 slides along the teeth toward the base 100, but when the pressure plate 230 releases the frame 1, the frame 1 naturally rebounds, and the rod body 321, under the action of the stopper 322, pushes the rack to rise through the teeth until the frame 1 stops rising, and then the pressure plate 230 presses the frame 1 again, repeating the rising action, and through multiple accumulations, the cumulative displacement of the frame 1 during the vibration period is tested, and the displacement of a single vibration can be calculated, thereby accurately measuring the shock absorption performance of the frame 1.

[0035] In this embodiment, the distance measuring device 300 further includes a second mounting plate and a chain structure 340. The chain structure 340 is disposed on the mounting plate, and the extension direction of the chain structure 340 is perpendicular to the base 100. The ruler 330 is a flexible body, and the ruler 330 is disposed on the chain. In this way, it is convenient to calculate long-distance movement and reduce the volume of the rectification test device.

[0036] In this embodiment, the connecting member 310 includes a first mounting plate 311, a clamping plate 312 and a screw rod 313. There are two clamping plates 312, and the two clamping plates 312 are slidably arranged on the first mounting plate 311 in a relative manner. The screw rod 313 is a bidirectional screw rod 313, and the screw rod 313 is connected to the two clamping plates 312 through the bidirectional screw rod 313 thereon.

[0037] When in use, the two clamping plates 312 are driven to move away from each other by the screw rod 313 until the two clamping plates 312 are respectively located on both sides of the frame 1, and then the screw rod 313 is rotated to drive the two clamping plates 312 to move relative to each other until the clamping plates 312 are clamped and fixed on the frame 1. The installation of the connecting member 310 is completed.

[0038] When the above-mentioned vehicle frame shock absorption test equipment is used, the vehicle frame 1 is first placed on the base 100 and located directly below the pressure plate 230, and then the telescopic power source 220 is started. The gap driving pressure plate 230 is pressed on the vehicle frame 1 and then released, and the vehicle frame rebounds naturally. In this process, the accumulated rebound rising distance of the vehicle frame 1 is measured through the toggle member 320 and the ruler 330, and then the shock absorption performance of the vehicle frame 1 is measured. The use of this test device can improve the accuracy of the shock absorption test of the vehicle frame, and provide accurate guidance for subsequent work.
