Description
Technical field:
The utility model is a kind of equipment that is used for frame for baby cart/front fork assembly impulse test, can finish the detection to the impact project of all kinds of frame for baby cart/front fork assemblies automatically.The utility model belongs to the perambulator technical field of measurement and test.
Background technology:
The safety verification of child's bicycle is the emphasis in the bicycle detection range.Child's bicycle in the process of moving, vehicle frame/front fork assembly ruptures owing to being subjected to accidental shock, this situation can cause very serious injury to children, so the shock resistance of vehicle frame/front fork assembly check is the emphasis in the child's bicycle safety verification.GB147646-2006 " child's bicycle safety requirements " has detailed regulation to the impulse test of vehicle frame/front fork assembly.
At present, the impact test equipment of vehicle frame/front fork assembly mainly is after utilizing the weight movement of falling object, vehicle frame/front fork assembly to be impacted.But because the bounce-back of vehicle frame/front fork assembly, weight tends to produce the secondary subsequent impacts behind one-shot, and such secondary subsequent impacts has produced and adverse influence test findings.
The utility model content:
This purpose of this utility model is, overcome the secondary pulse that produces after the weight drop impact, a kind of frame for baby cart/front fork assembly impact testing machine that can prevent secondary pulse originally is provided, after weight falls one-shot, at once clamp weight, prevent that weight from falling once more, produce follow-up secondary pulse.
For achieving the above object, design of the present utility model is: the electromagnet that utilizes the cylinder top to install has attracted weight, cylinders retract drives the height that weight rises to requirement, electromagnet disconnects, weight falls, and frame for baby cart/front fork assembly is impacted, behind the one-shot, clamp system clamps weight rapidly, prevents that weight from falling the follow-up secondary pulse of generation once more.Cylinder stretches out, and the electromagnet action attracts weight, and clamp system unclamps weight.Cylinders retract promotes weight, prepares to impact once more.
According to above-mentioned utility model design, the technical solution used in the present invention is as follows:
A kind of frame for baby cart of anti-secondary pulse/front fork assembly impact testing machine, comprise device framework, weight, lifting cylinder and test specimen erecting device, it is characterized in that two trapezoidal adjusting leading screws of the inboard fixed installation of described device framework, an installation frame and described trapezoidal adjusting leading screw revolve joins; Described lifting cylinder is installed on described installation frame top, promotes the fixedly connected electromagnet in cylinder lower end; Described weight is installed in below the described installation frame, and the small end of weight is adsorbed by electromagnet, and the middle part is by two clamp clampings that are fixedly mounted on the clamping cylinder end of installation frame bottom; Described test specimen erecting device is installed in described device framework bottom, makes the impact site aligning weight of test specimen fall the place.
Above-mentioned impact testing machine is furnished with automatic control system, and its structure is: a Fibre Optical Sensor is installed on described installation frame, is promoted cylinder and be furnished with the cylinder of lifting control electromagnetic valve, clamp cylinder and be furnished with the cylinder of clamping control electromagnetic valve; Described Fibre Optical Sensor, lifting cylinder control electromagnetic valve and clamping cylinder control electromagnetic valve are connected with a counting assembly respectively, have a programmable logic controller (PLC) to connect described electromagnet, counting assembly, lifting cylinder control electromagnetic valve, clamp cylinder control electromagnetic valve and a touch screen operation interface.
The utility model prevents that the beneficial effect of the frame for baby cart/front fork assembly impact testing machine of secondary pulse from being: can prevent the secondary pulse that weight produces effectively, entire test equipment moves automatically simultaneously, and test operation is simple.
Description of drawings:
Fig. 1 is the frame for baby cart/front fork assembly impact testing machine general structure synoptic diagram of anti-secondary pulse.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the control system control block diagram of testing machine shown in Figure 1.
Embodiment
An example accompanying drawings of the present utility model is as follows:
Referring to Fig. 1 and Fig. 2, the structure of the frame for baby cart/front fork assembly impact testing machine of this anti-secondary pulse is: two trapezoidal adjusting leading screws 7 are installed in device framework 1 inboard, installation frame 9 is installed in above two trapezoidal adjusting leading screws 7, and installation frame 9 can move up and down along with trapezoidal adjusting leading screw 7.Promote cylinder 8 and be installed in installation frame 9 tops, promote cylinder 8 tops electromagnet 6 is housed, weight 2 is installed in installation frame 9 bottoms, can be free to slide.Two clamps 3 are installed in two respectively and clamp cylinder 4 tops, clamp cylinder 4 and are fixed on installation frame 9 bottoms, and clamping cylinder 4 stretches out and is used for clamping weight 2.Test specimen erecting device 11 is installed in device framework 1 bottom, is used for fixing vehicle frame/front fork assembly 10.
