In preferred implementation as depicted in figs. 1 and 2, first connecting portion 33 comprises the first pedestal 33b and relative and spaced first web joint 33c and the second web joint 33d, first web joint 33c and the second web joint 33d is arranged on the first pedestal 33b, first web joint 33c and the second web joint 33d all has the first chute 33a, formed between first web joint 33c and the second web joint 33d be used for moving for the first end of first connecting rod 32a first dodge space, the both sides of the first end of first connecting rod 32a all have the first slide block 32c, two the first slide block 32c and two the first chute 33a one_to_one corresponding are slidably connected.First connecting portion 33 of said structure ensure that the motion credibility of link assembly 32.
In preferred implementation as shown in Figure 1, switching mechanism 30 also comprises second connecting portion 34 with the second chute 34a, second connecting portion 34 is arranged on upper cover 10, and second end of second connecting rod 32b has the second slide block 32d, and the second slide block 32d is slidably arranged in the second chute 34a.Owing to being provided with the second connecting portion 34 on upper cover 10, thus effectively avoiding on upper cover 10, offer chute, avoid destroying the original structure of upper cover 10, and effectively ensure that upper cover 10 open reliability.Preferably, the second connecting portion 34 is for having the brace of the second chute 34a.
As shown in Figure 1, the second end of link assembly 32 swings to be formed and swings camber line, and the second chute 34a is arc or linear, and one end of the second side of the close upper cover 10 of the second chute 34a is higher than one end of the first side near upper cover 10.Because one end of the second side of the close upper cover 10 of the second chute 34a is higher than the one end of the first side near upper cover 10, thus under the action of drive division 31, first connecting rod 32a drives second connecting rod 32b by the second Slideslip of the first side direction upper cover 10 of upper cover 10, thus is opened by upper cover 10.
In preferred implementation as shown in figures 1 and 3, second connecting portion 34 comprises the second pedestal 34b and relative and spaced 3rd web joint 34c and the 4th web joint 34d, 3rd web joint 34c and the 4th web joint 34d is arranged on the second pedestal 34b, 3rd web joint 34c and the 4th web joint 34d all has the second chute 34a, formed between 3rd web joint 34c and the 4th web joint 34d be used for moving for the first end of second connecting rod 32b second dodge space, the both sides of the first end of second connecting rod 32b all have the second slide block 32d, two the second slide block 32d and two the second chute 34a one_to_one corresponding are slidably connected.Second connecting portion 34 of said structure ensure that the motion credibility of link assembly 32.
In a not shown embodiment, link assembly 32 comprises first connecting rod 32a and second connecting rod 32b, first end and the drive division 31 of first connecting rod 32a are hinged, the first end of second connecting rod 32b is fixedly connected with second end of first connecting rod 32a, second end of second connecting rod 32b is fixedly connected with upper cover 10, has the first angle between first connecting rod 32a and second connecting rod 32b.Because the first end of second connecting rod 32b to be fixedly connected with second end of first connecting rod 32a and second end of second connecting rod 32b is fixedly connected with upper cover 10, thus the driving force suffered by first connecting rod 32a can be directly passed to second connecting rod 32b and act on on upper cover 10, thus ensure that the opening and closing reliable of upper cover 10.
Preferably, the tie point of the first end of second connecting rod 32b and second end of first connecting rod 32a and base 20 hinged.Due to the tie point of the first end of second connecting rod 32b and second end of first connecting rod 32a and base 20 hinged, thus not only ensure that link assembly 32 and the connection reliability of base 20, also make second connecting rod 32b have swingable feature.
Testing apparatus in the utility model also comprise control circuit, for detect the primary importance of drive division 31 the first limit sensors 40, for detecting the second limit sensors 41 of the second place of drive division 31, first limit sensors 40 is electrically connected with control circuit, second limit sensors 41 is electrically connected with control circuit, and control circuit is electrically connected with drive division 31.Owing to being provided with the first limit sensors 40 and the second limit sensors 41, thus the working position of link assembly 32 or drive division 31 can be detected according to the first limit sensors 40 and the second limit sensors 41, and judge the folding condition of upper cover 10 according to working position, thus control circuit is made effectively to control the duty of drive division 31.Certainly, can also select controller, such as PLC substitutes control circuit.
Because the motion state of drive division 31 can be controlled by control circuit, thus the folding degree of upper cover 10 and base 20 can be affected when the operating position of drive division 31 changes, that is, testing apparatus in the utility model can according to the concrete condition of tested object, by regulating the operating position of drive division 31, regulate the clamping force between upper cover 10 and base 20, thus avoid the problem of the tested object of the excessive damage of clamping force.
Preferably, the first limit sensors 40 and the second limit sensors 41 are proximity sensor.
In preferred implementation as shown in Figure 1, drive division 31 is orthoscopic cylinder, testing apparatus also comprises source of the gas and the switch valve for the on off operating mode that controls source of the gas and orthoscopic cylinder, source of the gas is communicated with orthoscopic cylinder, switch valve is arranged between source of the gas and orthoscopic cylinder, and switch valve is electrically connected with control circuit.In this embodiment, the first limit sensors 40 and the second limit sensors 41 are all arranged on orthoscopic cylinder, for the extension elongation of the cylinder rod of detection of straight lines formula cylinder.First limit sensors 40, near the first side of base 20, for the primary importance of detection of straight lines formula cylinder, is also extended position simultaneously, and now upper cover 10 closes; Second limit sensors 41 is near the second side of base 20, and for the advanced position of detection of straight lines formula cylinder, be also the second place, now upper cover 10 is opened simultaneously.
The opening of testing apparatus in the utility model, closing process: control circuit controls source of the gas to the service life of orthoscopic cylinder, to enable the accomplish linear reciprocating action smoothly of orthoscopic cylinder, orthoscopic cylinder moves to the second lateral movement of base 20 to pull first connecting rod 32a simultaneously, now first connecting rod 32a by force transmission to second connecting rod 32b, to make second connecting rod 32b that rectilinear motion is converted to rotary motion, thus perform the course of action opening upper cover 10, when orthoscopic cylinder bounces back to the second limit sensors 41 check point, second limit sensors 41 is triggered, and now supplies and is cut off to the source of the gas of orthoscopic cylinder, and the retracting action of orthoscopic cylinder stops, and remain on this position, thus upper cover 10 is made to be in the position be opened, control circuit such as can arrange the time delay a period of times such as timing relay, now source of the gas is to orthoscopic cylinder air feed, extend action is done to make orthoscopic cylinder, now orthoscopic cylinder moves to the first side of base 20, and second connecting rod 32b is at the effect lower swing of first connecting rod 32a, to make upper cover 10 gradually to base 20 1 lateral movement, close with base 20 to make upper cover 10, when the external part of orthoscopic cylinder reaches the check point of the first limit sensors 40, first limit sensors 40 detects and is triggered, now supply and be cut off to the source of the gas of orthoscopic cylinder, the extend action of orthoscopic cylinder stops, and remain on this position, thus make upper cover 10 in the close position.
Testing apparatus in the utility model effectively can improve testing efficiency, improves the automaticity of switch upper cover 10, effectively reduces the labour intensity of staff, meets the requirement of lean production.
